Abstract: A battery securing component configured to be mounted on a vehicle body is provided. A battery is vertically disposed on the vehicle body. The battery securing component includes: a lifting column vertically arranged on a side of the battery, and a lower end of the lifting column being threadedly connected to the vehicle body to cause the lifting column to be capable of moving up and down by rotating; a pressing sleeve rotatably sleeved on the lifting column and configured to be moved up and down in synchronization with the lifting column; a pressing arm being formed on the pressing sleeve by protruding toward the battery, higher than the battery) and an elastic engaging structure configured to drive the pressing sleeve to rotate in synchronization with the lifting column, and arranged between the pressing sleeve and the lifting column.

Abstract: Disclosed is a preparation method of a renewable epoxy asphalt material and a regeneration process. The preparation method comprises: I Vanillin and 4-aminophenol are reacted in water with stirring to obtain VAN-AP; II. VAN-AP is mixed with epichlorohydrin, to which tetrabutylammonium bromide is added and heated at 80 to 90° C. for reaction; sodium hydroxide solution is then added dropwise for reaction; the mixture is concentrated to obtain GE-VAN-AP; III. Preheated asphalt is mixed with a polyetheramine curing agent and a polyetheramine accelerator to form component A; GE-VAN-AP is melted as component B; the component A is evenly mixed with the component B to obtain a renewable epoxy asphalt material. During the regeneration, the resin phase structure in the epoxy asphalt is gradually depolymerized, whereby asphalt regenerant is used to restore the properties of the aged asphalt phase and reshape the resin phase structure to complete the regeneration.
