[0032] Example 1

[0033] The rear racks of existing electric vehicles are supports for placing goods. When the vehicle starts, the rear passengers will lean backward due to inertia, and the rear racks cannot protect the rear passengers, so driving safety needs to be improved.

[0034] In view of this, the present utility model provides a rear rack, including: a rear rack body 100, a horizontal connecting part 200, and an intermediate support assembly. The rear rack body 100 is provided with an installation mechanism for connecting to an electric vehicle frame. The horizontal connecting part 200 is connected to the rear rack body 100, and the intermediate support assembly is rotatably connected to the horizontal connecting part 200. The intermediate support assembly is provided with a limiting mechanism 300, which has an adjustment state that enables the intermediate support assembly to rotate and a limiting state that limits and fixes the intermediate support assembly.

[0035] The rear rack can be fixed to the electric vehicle frame via the mounting mechanism on the rear rack body 100, ensuring a stable connection between the rear rack and the vehicle body. The rear rack body 100 can bear the load on the rear rack, and the intermediate support assembly can transfer the inertial force of the rear passengers to the rear rack body 100. The intermediate support assembly can rotate relative to the transverse connecting part 200. In the adjustment state, the limiting mechanism 300 can cause the intermediate support assembly to rotate, thereby adjusting the angle of the intermediate support assembly relative to the rear rack body 100. After the angle of the intermediate support assembly relative to the rear rack body 100 is adjusted, the limiting mechanism 300 can limit and fix the intermediate support assembly, making it stable in a certain position. After the intermediate support assembly rotates upward by 90°, it can not only fit snugly against the waist of the rear passengers to improve comfort, but also effectively protect the rear passengers. When the intermediate support assembly is parallel to the rear rack body 100, it can provide a larger load-bearing area for goods and can also act as a support for securing goods with ropes, preventing swaying and damage to goods when riding on bumpy roads.

[0036] In an optional embodiment, the intermediate support assembly includes an intermediate support 400 and a mounting part 500, which are fixedly connected. A horizontal connecting part 200 is connected to a mounting bracket 600, and the mounting part 500 is rotatably connected to the mounting bracket 600. A limiting mechanism 300 is disposed on the mounting bracket 600 and the intermediate support 400.

[0037] Please see Figure 1The bottom of the intermediate support 400 is fixedly connected to the mounting part 500, specifically by welding, to ensure that the intermediate support 400 can move synchronously with the mounting part 500. The mounting part 500 can be a mounting rod or a mounting tube. A sponge backrest can be provided on one side of the intermediate support 400. When the intermediate support 400 is upright, the sponge backrest rests against the lumbar region of the rear passengers, further improving the comfort of the rear passengers. The transverse connecting part 200 can be a tubular structure or a rod-like structure. Mounting brackets 600 are fixedly installed at both ends of the mounting part 500 on the transverse connecting part 200. The mounting part 500 can rotate relative to the mounting bracket 600, but it can only rotate and cannot move.

[0038] In an optional embodiment, the limiting mechanism 300 includes a ratchet assembly and a push rod assembly. The ratchet assembly includes a ratchet 310 and a pawl 320 that can engage and cooperate. The ratchet 310 is disposed on the mounting bracket 600, and the pawl 320 is disposed on the intermediate bracket 400. The push rod assembly is connected to the pawl 320 for driving the pawl 320 to engage or disengage from the ratchet 310.

[0039] Please see Figure 2 In the ratchet assembly, the ratchet 310 and pawl 320 engage in a one-way meshing mechanism to limit and fix the position of the intermediate support 400. The ratchet 310 is riveted to the mounting bracket 600, and the pawl 320 is rotatably mounted on the intermediate support 400. The push rod assembly can drive the pawl 320 to engage with the ratchet 310, thereby limiting and fixing the intermediate support 400. Furthermore, the push rod assembly can also drive the pawl 320 to disengage from the ratchet 310, thereby adjusting the angle of the intermediate support 400.

[0040] In an optional embodiment, the ratchet assembly further includes a pin 330, which is mounted on the intermediate support 400, and the pawl 320 is rotatably connected to the pin 330.

[0041] The pin 330 is fixedly mounted on the intermediate bracket 400. The push rod assembly can act on the pawl 320 to make the pawl 320 rotate relative to the pin 330, that is, rotate to the position of engaging or disengaging with the ratchet 310.

[0042] In an optional embodiment, the push rod assembly includes a push rod 340, an elastic element 350, and a fixed bracket 360. The push rod 340 is slidably connected to the fixed bracket 360. The elastic element 350 is sleeved on the push rod 340 and connected to the fixed bracket 360. When the pawl 320 is separated from the ratchet 310, the elastic element 350 causes the pawl 320 to have a tendency to engage with the ratchet 310.

[0043] Please see Figure 2The fixed bracket 360 is fixedly installed on the intermediate bracket 400. The push rod 340 can slide up and down relative to the fixed bracket 360. When the push rod 340 is pressed down and moves downward relative to the fixed bracket, the push rod 340 acts on the pawl 320, causing the pawl 320 to rotate around the pin 330 to the position where it is separated from the ratchet 310. At this time, the angle of the intermediate bracket 400 can be adjusted. At this time, the elastic element 350 is compressed, causing the push rod 340 to tend to return to its original position upward. After the push rod 340 is released, the push rod 340 moves upward, and at the same time, the pawl 320 rotates around the pin 330 to the position where it engages with the ratchet 310, thereby achieving the limiting and fixing of the intermediate bracket 400 after the angle adjustment is completed.

[0044] In an optional embodiment, the push rod 340 includes a pressing part 341 and an abutting part 342, which are disposed opposite to each other at both ends of the push rod 340. An elastic member 350 is disposed between the pressing part 341 and the fixed bracket 360. The abutting part 342 is connected to the pawl 320 for driving the pawl 320 to rotate around the pin 330 to a position where it engages or disengages from the ratchet 310.

[0045] Please see Figure 2 The pressing part 341 is located at the top of the push rod 340, and the abutting part 342 is located at the bottom of the push rod 340. When the pressing part 341 is pressed down, the elastic element 350 is compressed, so that the pressing part 341 is subjected to an upward elastic force. The abutting part 342 is connected to the pawl 320 in a manner including but not limited to the abutting part 342 being fixed to one end of the pawl 320, as long as the movement of the abutting part 342 can drive the pawl 320 to rotate around the pin 330.

[0046] In an optional embodiment, the rear shelf body 100 includes a first rear shelf sub-tube 110, a connecting tube 120, and a second rear shelf sub-tube 130. The first rear shelf sub-tube 110 and the second rear shelf sub-tube 130 are arranged at intervals relative to each other. The two ends of the connecting tube 120 are respectively connected to the corresponding ends of the first rear shelf sub-tube 110 and the second rear shelf sub-tube 130. The two ends of the horizontal connecting part 200 are respectively connected to the middle parts of the first rear shelf sub-tube 110 and the second rear shelf sub-tube 130. The mounting mechanism is disposed on the first rear shelf sub-tube 110, the second rear shelf sub-tube 130, and the horizontal connecting part 200.

[0047] Please see Figure 1 The first rear rack sub-tube 110, the connecting tube 120, and the second rear rack sub-tube 130 can bear the load on the rear rack. The intermediate support 400 and the mounting part 500 can transfer the inertial force of the rear passengers to the first rear rack sub-tube 110, the connecting tube 120, and the second rear rack sub-tube 130 through the horizontal connecting part 200.

[0048] In an optional embodiment, the installation mechanism includes a first mounting plate 710, a second mounting plate 720, and a third mounting plate 730. The first mounting plate 710 is connected to the first rear shelf sub-tube 110, the second mounting plate 720 is connected to the second rear shelf sub-tube 130, and the third mounting plate 730 is connected to the horizontal connecting part 200. The first mounting plate 710, the second mounting plate 720, and the third mounting plate 730 are all provided with an adjustment structure.

[0049] Please continue reading Figure 1 The rear rack is fixed to the electric vehicle frame via the first mounting plate 710, the second mounting plate 720, and the third mounting plate 730, ensuring a stable and reasonable connection between the rear rack and the vehicle body. The adjustable structure allows the rear rack to be installed on a wider variety of electric vehicle frames, improving its practicality.

[0050] Specifically, the adjustment structure includes a strip hole 800 for inserting fasteners. Installation can be achieved by inserting fasteners into the corresponding holes in the strip hole 800 and the electric vehicle frame, making installation simple.
