[0005] The technical scheme adopted by the present application to solve its technical problems is: a base plate of an electric vehicle, comprising a horizontally arranged base plate body, a plurality of mounting holes are arranged on the upper end surface of the base plate body and are spaced apart along the length direction thereof, a first mounting block is protrudingly arranged on the front end of the lower end surface of the base plate body, a second mounting block is protrudingly arranged on the rear end of the lower end surface of the base plate body, and elastically deformable clamping blocks are symmetrically protrudingly arranged on the two side edges of the lower end surface of the base plate body, the base plate body is clamped and matched with the two side edges of the vehicle frame through the clamping blocks, the clamping blocks are elastically deformed and buckled on the surface of the vehicle frame when clamped, a hinge is hingedly connected to the first mounting block, a lock catch is connected to the second mounting block, a flat plate is placed on the upper end surface of the base plate body, a plurality of through holes are arranged on the flat plate and correspond to the mounting holes one by one, and a positioning assembly is arranged on the two side edges of the upper end surface of the base plate body close to the flat plate, the positioning assembly is used for positioning the placement position of the flat plate on the base plate body so that the through holes of the flat plate are quickly aligned with the mounting holes of the base plate body.

[0006] The effects of the above components are: when implemented, the base plate body is preliminarily fixed with the vehicle frame through the front end first mounting block hingedly connected with the hinge, the rear end second mounting block connected with the lock catch, and the two side elastically deformable clamping blocks clamped with the vehicle frame, the flat plate is placed on the upper end of the base plate body, the position of the flat plate is limited by the positioning assembly, and the through holes are quickly aligned with the mounting holes. The effect is to solve the problem of aligning the holes of the flat plate and the base plate body, reduce the adjustment operation during screw installation, improve the overall installation efficiency, and enhance the stability of the connection with the vehicle frame through the elastic clamping of the clamping blocks.

[0007] Preferably, a plurality of placement grooves extending along the width direction of the lower end surface of the base plate body are further arranged on the lower end surface of the base plate body, rubber blocks are embedded in the placement grooves, the lower end surface of the rubber blocks protrudes from the lower end surface of the base plate body, and the rubber blocks are used to fill the gap between the base plate body and the vehicle frame when they are in contact, and to achieve buffering through the elastic deformation of the rubber blocks themselves when the electric vehicle bounces.

[0008] The effects of the above components are: the placement grooves are arranged on the lower end surface of the base plate body and the rubber blocks are embedded therein, and the lower end of the rubber blocks protrudes from the lower end surface of the base plate body. When the base plate body is connected with the vehicle frame, the rubber blocks fill the gap therebetween to avoid hard contact, and when the electric vehicle travels on a bumpy road section, the rubber blocks are elastically deformed under extrusion to absorb vibration energy. The effect is to reduce the collision noise between the base plate body and the vehicle frame, buffer the vibration, protect the connection part of the base plate body and the vehicle frame, and prolong the service life.

[0009] Preferably, the clamping blocks are made of elastic material, and the clamping blocks are elastically deformed in the direction close to the base plate body under lateral extrusion of the vehicle frame during contact with the vehicle frame, and are restored to be tightly buckled on the surface of the vehicle frame after being clamped into the edge of the vehicle frame.

[0010] The effect achieved by the above-mentioned component is that the clamping block is made of elastic material such as rubber, and is in contact with the vehicle frame during installation and is pressed by lateral force to bend and deform towards the base plate body. After being clamped into the edge of the vehicle frame, the elastic potential energy is released to restore the clamping block to its original state, tightly clamping the surface of the vehicle frame. The effect is to achieve firm clamping of the clamping block and the vehicle frame through elastic deformation, prevent the base plate body from loosening during vehicle driving, and enhance the connection stability. At the same time, the installation process is simplified, and no additional fixing parts are needed to achieve preliminary positioning.

[0011] Preferably, the positioning assembly comprises a positioning block and a first baffle. The positioning block is symmetrically protruded on the two corner regions of the upper end face of the base plate body in a circular arc shape, and the inner side arc surface of the positioning block is adaptively fitted with the outer side wall of the corner of the flat plate. The first baffle is vertically protruded on the upper end face of the positioning block, and the inner side wall of the first baffle is in abutment with the edge of the upper end face of the flat plate. The first baffle is used to limit the upper end of the flat plate to prevent the flat plate from being warped.

[0012] The effect achieved by the above-mentioned component is that the positioning block is protruded on the two corners of the upper end of the base plate body, and the circular arc-shaped inner side wall is fitted with the corner outer side wall of the flat plate to limit the horizontal displacement of the flat plate. The first baffle is vertically protruded on the upper end face of the positioning block, and the inner side wall is in abutment with the upper end edge of the flat plate to limit the upward warping of the flat plate. The effect is to quickly achieve the position alignment of the flat plate and the base plate body through the fitting positioning of the positioning block and the vertical limiting of the first baffle, to ensure the accurate correspondence of the through hole and the mounting hole, and to prevent the hole position from being deviated due to the warping of the flat plate under stress, thereby improving the installation efficiency and stability.

[0013] Preferably, a slanted groove is formed in the side wall of the first baffle away from the positioning block, and the slanted groove extends obliquely from the upper end face to the lower end face, so that the gap between the first baffle and the base plate body has an entrance size larger than the internal size to facilitate the edge of the flat plate to slide into the gap.

[0014] The effect achieved by the above-mentioned component is that the slanted groove is formed in the side wall of the first baffle away from the positioning block, and the slanted groove extends obliquely from the upper end face to the lower end face, so that the gap between the first baffle and the base plate body has an entrance size larger than the internal size. When installing the flat plate, the edge of the flat plate can smoothly slide into the gap along the slanted groove, reducing the jam caused by the narrow entrance. The effect is to reduce the difficulty of alignment when placing the flat plate, improve the installation convenience, and avoid damage caused by hard contact between the edge of the flat plate and the first baffle.

[0015] Preferably, the two side walls of the positioning block are symmetrically connected with a reinforcing plate. One end of the reinforcing plate is fixedly connected with the outer side wall of the positioning block, and the other end of the reinforcing plate is fixedly connected with the upper end face of the base plate body to enhance the connection strength of the positioning block and the base plate body.

[0016] The effect achieved by the above-mentioned components is that the two side walls of the positioning block are fixedly connected with the reinforcing plate, one end of the reinforcing plate is welded or integrally formed with the outer side wall of the positioning block, and the other end is fixed with the upper end face of the base plate body. The reinforcing plate forms a triangular support structure to disperse the force received by the positioning block. The effect is to enhance the connection strength of the positioning block and the base plate body, prevent the positioning block from deforming or falling off due to long-term stress (such as flat plate extrusion), and ensure the long-term stable use of the positioning assembly.

[0017] Preferably, the positioning assembly further comprises a second baffle and a spring, and the upper end face of the positioning block is provided with a slot, and the second baffle is inserted into the slot and can slide up and down in the slot.

[0018] The effect achieved by the above-mentioned components is that the upper end face of the positioning block is provided with a slot, the second baffle is inserted into the slot and can slide up and down, and the spring is vertically connected between the lower end of the second baffle and the bottom wall of the slot. When installing the flat plate, the second baffle is pulled upward to compress the spring, and then released after the flat plate is placed, and the spring returns to push the second baffle to slide downward, and the inner side wall thereof abuts against the upper end face of the flat plate. The effect is to realize flexible vertical limiting of the flat plate by the second baffle and the spring, adapt to the installation requirements of flat plates of different thicknesses, and at the same time, enhance the tightness of the limiting to prevent the flat plate from shaking.

[0019] Preferably, the spring is vertically arranged in the slot, one end of the spring is connected with the lower end face of the second baffle, and the other end of the spring is connected with the bottom wall of the slot. The spring is used to drive the second baffle to return to position after the second baffle is pulled upward, so that the inner side wall of the second baffle abuts against the upper end face of the flat plate.

[0020] The effect achieved by the above-mentioned components is that the positioning block is designed in a U shape, the opening of the U-shaped positioning block faces the corner of the flat plate, and the inner side wall of the U-shaped positioning block is adapted to the outer side wall of the corner of the flat plate. When installing, the corner of the flat plate is embedded in the U-shaped positioning block, and the horizontal displacement of the flat plate is limited by the three-directional fitting. The effect is that compared with the arc-shaped positioning block, the U-shaped positioning block can more comprehensively wrap the corner of the flat plate, further improving the positioning accuracy and ensuring the stability of the alignment of the through hole and the mounting hole.

[0021] Preferably, the positioning block is in a U shape, the opening of the positioning block faces the corner of the flat plate, and the inner side wall of the U-shaped positioning block is adapted to the outer side wall of the corner of the flat plate. The outer side wall of the second baffle is provided with a plurality of anti-slip blocks distributed along the height direction of the second baffle, and the surface of the anti-slip block is provided with anti-slip lines. The anti-slip lines are used to increase the friction between the hand and the second baffle.

[0022] The effect achieved by the above-mentioned component is that a plurality of anti-skid blocks with anti-skid lines are arranged on the outer wall of the second baffle and are distributed at intervals in the height direction. When the operator pulls the second baffle, the hands contact the anti-skid blocks, and the anti-skid lines increase the friction. The effect is to facilitate the operator to quickly and labor-savingly pull the second baffle, avoid slipping, and improve the operation convenience.

[0023] The effect achieved by the above-mentioned component is that: In summary, the beneficial effects of the present application are: In use, the hinges and the lock are placed on the upper end of the frame, and the first mounting block and the second mounting block at the lower end of the base plate body are in contact with the hinges and the lock, respectively. Then, the flat plate is placed on the upper end of the base plate body. At this time, the positioning assembly is used to quickly align the through hole on the flat plate with the mounting hole on the base plate body. Then, the screws are used to threadedly fix the screws through the through hole on the surface of the flat plate and the mounting hole on the surface of the base plate body, and part of the screws are threadedly fixed through the first mounting block and the second mounting block and the hinges and the lock. Then, the installation and fixation of the base plate body, the flat plate, the hinges and the lock on the frame are completed. Then, the cushion is fixed to the upper end of the base plate body for use of the electric vehicle.

[0024] The gap between the base plate body and the frame is filled when the base plate body is connected with the frame, and the rubber block is used to buffer when the electric vehicle encounters a bumpy road section, so as to avoid collision and sound at the connection between the base plate body and the frame.

[0025] When the flat plate is in contact with the base plate body, the two corners of the flat plate are in contact with the positioning blocks at the two corner regions of the base plate body to quickly position the position of the through hole on the surface of the flat plate and the mounting hole on the surface of the base plate body. The first baffle fixed on the upper end of the positioning block is used to limit the upper end of the flat plate to avoid the flat plate being lifted on one side under stress, which affects the positioning effect. The use of the positioning assembly can quickly and accurately align the through hole on the flat plate with the mounting hole on the surface of the base plate body, avoid the screws being unable to smoothly pass through the hole position for fixation during the installation process, cause the screws to be difficult to be clamped or need additional adjustment and operation, increase the complexity of installation, and significantly reduce the installation efficiency and prolong the installation time, thereby improving the use effect of the base plate body.
