Abstract: Disclosed are a shock absorber performance testing device and method for vehicle engineering. The device includes a box body and a box door, where a U-shaped frame is fixedly connected to a bottom of the box body, a motor is fixedly connected to a bottom of the U-shaped frame, a rotating disk is fixedly connected to an output end of the motor, a moving block is connected to the rotating disk by a guide mechanism, two first connecting blocks symmetrically arranged are fixedly connected to a bottom of the moving block, two second connecting blocks symmetrically arranged are fixedly connected to a top of the rotating disk, and insertion holes are formed on side walls of the first and second connecting block. The present invention facilitates continuous multiple impact tests and adjusts the frequency and amplitude of the impact, thereby making the test more convenient and achieving better test results.

Abstract: A signal feedback device used for an automotive locking apparatus is provided, comprising a car power supply, a motor, a transmission, an actuating lever, a signal feedback module, and a body control module. The signal feedback module is provided with a first feedback circuit, a second feedback circuit, and a third feedback circuit. The first feedback circuit is connected in series to a first resistor and a first on-off switch. The second feedback circuit is connected in series to a second resistor and a second on-off switch. The third feedback circuit is connected in series to a third resistor. The actuating lever is provided with a touch spot, and the corresponding circuits are turned on under driving of linear movement of the actuating lever, to provide different signal feedbacks.

Abstract: An electric grill, more particularly, a grill convenient for storage is provided in the present invention. The present invention comprises: a main body, a pan for holding and cooking food disposed on said main body, two hand grips disposed on the left and right side of said pan, two moveable lock units respectively disposed on the left and right side of said body corresponding to said hand grips, and said lock units can lock up said pan or said hand grips. The pan and hand grips won't fall from the body when it is laid vertically. Furthermore, said main body comprises a first supporting bar and a lid provided with a second supporting bar; said first and second supporting bar define and form a supporting-plane on the center of gravity of the frontal side or rear side of said body and said body lid. In this way, the grill won't fall when it is vertically laid.
