[0008] The present invention provides a rear cargo rack at the rear of an electric vehicle, which has the following beneficial effects: 1. The rear rack at the rear of the electric vehicle, through the blocking effect of the convex strips, cooperates with the inclined surface on the top of the waterproof cover and the evenly opened inclined grooves on the top, so that after rainwater falls on the top of the waterproof cover, the rainwater is discharged to the side away from the rear of the vehicle.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0016] The first embodiment, as Figure 1 to Figure 2 and Figures 7 and 8 As shown, the present invention provides a technical solution: a rear shelf at the rear of an electric vehicle, comprising: A mounting bracket 1 is connected to the rear of the electric vehicle to fix the shelf to the rear of the electric vehicle; A buffer assembly 2, the buffer assembly 2 is mounted on a side of the mounting bracket 1 away from the rear of the electric vehicle; A cargo box 3, wherein the cargo box 3 has cargo storage space therein and the cargo box 3 is fixedly mounted on the top of the buffer assembly 2; The storage box 3 includes a box body 31 and a waterproof cover 32. The waterproof cover 32 is rotatably mounted on the top of the box body 31. The inner wall of the box body 31 is away from the rear of the vehicle and is an inclined surface inclined inward from top to bottom. The bottom surface of the inner wall of the box body 31 is an inclined surface inclined downward at one end away from the rear of the vehicle. A convex strip 33 is fixedly mounted on the top of the waterproof cover 32 near the rear of the vehicle. The top of the waterproof cover 32 is an inclined surface inclined downward at one end away from the convex strip 33. An inclined groove is provided on the top of the waterproof cover 32. The goods are placed in the box body 31, and then the box is opened through the waterproof cover 32. The top of the body 31 is sealed. At the same time, in heavy rain weather, rainwater falling on the top of the waterproof cover 32 cooperates with the inclined surface and the inclined groove at the top. After the rainwater falls into the top of the waterproof cover 32, the rainwater is diverted to the side away from the rear of the vehicle, so that the rainwater falls from the side away from the rear of the vehicle. At the same time, the convex strip 33 cooperates with the guidance of the rainwater to block the side of the waterproof cover 32 close to the rear of the vehicle, so as to avoid rainwater dripping along the waterproof cover 32 to the position of the electric vehicle seat near the rear of the vehicle in heavy rain weather, causing the seat to be wet, and the inclined groove is evenly installed on the top of the waterproof cover 32 along the axial direction.

[0017] The inner wall of the waterproof cover 32 is snapped into the top of the outer side of the box body 31, and a water guide groove 35 is provided on the side of the bottom of the box body 31 away from the rear of the vehicle. A partition plate 34 is fixedly installed on the bottom of the inner wall of the box body 31, and a through groove is provided on the top of the partition plate 34, and the through groove is evenly installed on the top of the partition plate 34 along the axial direction. The bottom of the goods is isolated from the bottom of the box body 31 by the partition plate 34. When the goods are food, after the overflowed soup drips on the bottom of the box body 31, the soup can be discharged along the water guide groove 35 along the inclined surface of the bottom of the inner wall of the box body 31, and there is a gap between the bottom of the partition plate 34 and the bottom of the inner wall of the box body 31.

[0018] The second embodiment is based on the first embodiment. Figure 3 to Figure 4As shown, the mounting bracket 1 includes a connecting side plate 11, the number of the connecting side plates 11 is two, and a circular groove is opened at one end of the connecting side plate 11, and a rubber gasket 16 is fixedly installed at the bottom of the connecting side plate 11. The rubber gasket 16 is located at the bottom of the circular groove of the connecting side plate 11, and a connecting bolt 15 is installed at the circular groove of the connecting side plate 11. Through the circular groove of the connecting side plate 11, the connecting bolts 15 are used to fix it to both sides of the rear end of the electric vehicle. When fixed, the rubber gasket 16 contacts the rear end of the electric vehicle, and the rubber plate 12 and the rubber sleeve plate 14 cooperate with the rubber gasket 16 to connect with the electric vehicle. The connecting side plate 11 is fixedly connected to the rear end of the electric vehicle through the connecting bolts 15, and a rubber plate 12 is fixedly installed on the opposite side of the connecting side plate 11 close to the rear end, and a clamping cross bar 13 is fixedly installed between the connecting side plates 11, and a rubber sleeve 14 is fixedly installed on the outer side of the clamping cross bar 13. During the installation and bumpy riding process, the deformation characteristics of the rubber can buffer the force when it is subjected to the force, so as to protect the electric vehicle when the load is heavy. The outer side of the rubber sleeve 14 fits tightly with the rear end of the vehicle, and the opposite side of the rubber plate 12 fits with the rear end of the vehicle.

[0019] The third embodiment is based on the first and second embodiments. Figure 5 to Figure 6 As shown, the buffer assembly 2 includes a slot frame 21, and both sides of the slot frame 21 are fixedly installed with fixed clamps 22. The slot frame 21 is fixedly installed on the side of the opposite surface of the connecting side plate 11 away from the rear of the vehicle through the fixed clamps 22. The inner wall of the slot frame 21 is slidably installed with a sliding frame plate 23. The sliding frame plate 23 is composed of a cross plate at the bottom and sliders on both sides of the top of the cross plate, and the opposite surfaces of the sliders are inclined surfaces inclined outward from top to bottom. During the vibration process, the weight of the goods in the storage box 3 is transmitted to the sliding frame plate 23 through the connecting frame 25, so that when the sliding frame plate 23 impacts downward, the force is transmitted to the inclined surface of the inclined surface block 26 through the inclined surface of the slider, so that When the sliding frame plate 23 impacts downward, the inclined plane block 26 compresses the elastic gasket 27 through the slide plate 28, so that the elastic gasket 27 is compressed and deformed during the impact. During the deformation process, the rebound force gradually increases, so that the acting force between the inclined plane block 26 and the sliding frame plate 23 gradually increases, increasing the friction force. At the same time, after the downward impact, the rebound force resets the sliding frame plate 23 through the contact between the inclined surface of the inclined plane block 26 and the sliding frame plate 23. At the beginning of the reset, the contact pressure is the largest, and the friction force is the largest, reducing the reset speed. The inner wall of the groove frame 21 is slidably installed with a slide plate 28, and the center position of the non-opposite surface of the slide plate 28 is fixedly installed with an inclined plane block 26.

[0020] The side of the inclined plane block 26 away from the slide plate 28 is an inclined plane, and the inclined plane of the inclined plane block 26 is adapted to the opposite side of the slide block, and an elastic gasket 27 is fixedly installed between the slide plates 28, and the elastic gasket 27 is located inside the groove frame 21. Circular holes are provided at the tops of both sides of the slide frame plate 23. According to different load weights, the fixing bolts 24 are made to slide in the slide grooves of the connecting frame 25, so that the connection position of the connecting frame 25 and the slide frame plate 23 is changed. When the load weight is large, the connecting frame 25 drives the storage box 3 so that the center position of the load is close to the rear of the vehicle, so as to avoid a large distance between the load center and the rear of the vehicle, which causes greater vibration to the goods in the storage box 3 during bumps, and a connecting frame 25 is installed at the top of the inner wall of the slide frame plate 23, and slide grooves are provided on both sides of the connecting frame 25. Fixing bolts 24 are installed at the circular holes of the slide frame plate 23, and the slide frame plate 23 is fixedly connected to the connecting frame 25 through the fixing bolts 24 through the slide grooves.

[0021] When in use, the rear rack is installed at the rear of the electric vehicle through the mounting bracket 1. When goods need to be placed, the goods are placed in the storage box 3 for storage. At the same time, during riding, the weight of the goods is transferred to the buffer component 2 through the storage box 3. When riding is bumpy, the buffer component 2 is fixed by the mounting bracket 1, and the storage box 3 and the goods inside are buffered by the buffer component 2 during bumps.

[0022] When the rear rack is installed at the rear of the vehicle through the mounting bracket 1, it is fixed to both sides of the rear of the electric vehicle by connecting the circular grooves of the side panels 11 with the connecting bolts 15. When fixed, it contacts the rear of the electric vehicle through the rubber gasket 16, and contacts the electric vehicle through the rubber plate 12 and the rubber sleeve 14 in conjunction with the rubber gasket 16. During the installation and bumpy riding process, the deformation characteristics of the rubber can buffer the force when it is subjected to the force, so the electric vehicle is protected when the load is heavy.

[0023] In the buffer assembly 2, according to the different load weights, the fixing bolts 24 slide in the sliding grooves of the connecting frame 25, so that the connection position between the connecting frame 25 and the sliding frame plate 23 changes. When the load weight is large, the connecting frame 25 drives the storage box 3 so that the center of the load is close to the rear of the vehicle, so as to avoid a large distance between the load center and the rear of the vehicle, which causes greater vibration to the goods in the storage box 3 during bumps. At the same time, during the vibration process, the weight of the goods in the storage box 3 is transmitted to the sliding frame plate 23 through the connecting frame 25, so that when the sliding frame plate 23 impacts downward, the sliding block The inclined surface transmits the force to the inclined surface of the inclined surface block 26, so that the inclined surface block 26 compresses the elastic gasket 27 through the slide plate 28 when the sliding frame plate 23 impacts downward, so that the elastic gasket 27 is compressed and deformed during the impact. During the deformation process, the rebound force gradually increases, so that the force between the inclined surface block 26 and the sliding frame plate 23 gradually increases, increasing the friction force. At the same time, after the downward impact, the rebound force is through the contact between the inclined surface of the inclined surface block 26 and the sliding frame plate 23, so that it is reset. At the beginning of the reset, the contact pressure is the largest, and the friction force is the largest, which reduces the reset speed.

[0024] In the storage box 3, the goods are placed in the box body 31, and then the top of the box body 31 is sealed by the waterproof cover 32. At the same time, in heavy rain weather, rainwater falling on the top of the waterproof cover 32 cooperates with the inclined groove through the inclined surface on the top. After the rainwater falls into the top of the waterproof cover 32, the rainwater is diverted to the side away from the rear of the vehicle, so that the rainwater falls from the side away from the rear of the vehicle. At the same time, the convex strip 33 cooperates with the guidance of rainwater to block the side of the waterproof cover 32 close to the rear of the vehicle to prevent rainwater from dripping along the waterproof cover 32 to the position of the electric vehicle seat near the rear of the vehicle during heavy rain weather, causing the seat to be wet. At the same time, the bottom of the goods is isolated from the bottom of the box body 31 by the partition board 34. When the goods are catering food, after the overflowing soup drips to the bottom of the box body 31, the soup can be discharged along the inclined surface at the bottom of the inner wall of the box body 31 along the water guide groove 35.

[0025] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
