[0012] A further technical solution is: the fixing member is a bolt.
[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
[0014] 1. Due to the use of the connection plate, the installation base plate, the load-bearing mechanism, the shock-absorbing assembly and the buffer assembly, the load-bearing device can be installed on the rear beam of the load-bearing electric vehicle frame through the installation base plate. When the goods need to be fixed, the staff only needs to place the goods on the load-bearing mechanism to fix them. Since the load-bearing mechanism is detachably installed on the top of the connection plate, it is convenient for the staff to disassemble and repair the load-bearing mechanism. When the load-bearing electric vehicle equipped with the load-bearing device is traveling on a bumpy road section, the load-bearing mechanism with the goods placed on it will produce continuous vibration. During the vibration process, the load-bearing mechanism will cause the connection plate to exert a certain force on the shock-absorbing assembly and the buffer assembly at the same time, and compress the shock-absorbing assembly and the buffer assembly. At this time, the shock-absorbing assembly and the buffer assembly in a compressed state will produce a certain buffering effect on the docking plate 1, so that the goods placed on the load-bearing mechanism can remain stable when encountering a bumpy road section, and thus can play a certain protective role for the goods. Due to the use of the swing member, the first spring, the damper, the slider, the slide rail, the swing rod, the first pin seat and the second pin seat, when the connecting plate compresses the shock absorbing component and the buffer component at the same time, the two sets of swing rods will swing at a certain angle at the same time, and the two sets of swing rods will push the corresponding two sets of sliders to slide closer on the slide rail during the swinging process. When the two sets of sliders slide closer on the slide rail, they will compress the first spring and the damper at the same time. At this time, the first spring and the damper in the compressed state can produce a certain buffering effect on the connecting plate, and then can play a certain protective role on the goods placed in the load-bearing mechanism.
[0015] 2. Due to the use of the load frame, installation slot, fixings and positioning mechanism, and because the fixings pass through the installation slot and are threadedly connected to the connecting plate, it is convenient for the staff to disassemble and repair the load frame. When the goods need to be fixed, the staff only needs to place the goods in the load frame, and the two sets of positioning mechanisms on the load frame will firmly rest on both sides of the goods, and the goods placed in the load frame can be fixed at this time. The whole operation is simple and reliable, which is convenient for the staff to operate.
[0016] 3. Due to the use of the baffle, the second spring and the first telescopic rod, when the cargo is placed on the load rack, the two sides of the cargo will respectively lean against the corresponding baffles, and will simultaneously exert a certain extrusion force on the two groups of baffles, so that the two groups of baffles compress the corresponding second springs and the first telescopic rod respectively. At this time, the second spring in a compressed state will exert a certain reaction force on the baffle, so that the two groups of baffles can be firmly against the two sides of the cargo, and the cargo can be fixed at this time. When the second spring is in a compressed state, the first telescopic rod can prevent the second spring from deforming, so it can play a certain protective role on the second spring.
[0017] 4. Due to the setting of rubber pads, when the baffle is against the goods, the rubber pads on the baffle will contact the goods, thus providing a certain degree of protection for the goods.
[0018] 5. Due to the use of the third spring and the second telescopic rod, one end of the third spring is fixedly connected to the connecting plate, and the other end of the third spring is fixedly connected to the mounting base plate. Therefore, the load-carrying mechanism with goods placed thereon will exert a certain pressure on the third spring due to its own gravity, and compress the third spring to a certain extent. At this time, the third spring in a compressed state can play a certain supporting role on the connecting plate. When the third spring is in a compressed state, the second telescopic rod can prevent the third spring from deforming, and thus can play a certain protective role on the third spring.

DETAILED DESCRIPTION

When the electric vehicle is traveling on a bumpy road, the cargo placed on the load-bearing device will be subjected to a great shock, which will cause unnecessary bumps to the cargo itself and lead to damage to the cargo.
[0025] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:
[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The load-bearing mechanism 3 is mounted on the connecting plate 1. The shock-absorbing component 4 is arranged between the connecting plate 1 and the mounting base plate 2. A plurality of groups of buffer components 5 arranged in a rectangular array are arranged on the mounting base plate 2. Each group of buffer components 5 is connected to the connecting plate 1.
[0028] The shock absorbing assembly 4 includes a swinging member 41, a first spring 42 for buffering the connecting plate 1, a damper 43 arranged in the first spring 42, a slider 44 for compressing the first spring 42, and a slide rail 45 arranged on the mounting base plate 2. Two groups of sliders 44 are slidably connected to the slide rail 45. The two groups of sliders 44 are both provided with a swinging member 41. The two groups of swinging members 41 are both connected to the connecting plate 1. Both ends of the first spring 42 and the damper 43 are respectively connected to the two groups of sliders 44. The swinging member 41 includes a swinging rod 411, a first pin shaft seat 412 arranged on the slider 44, and a second pin shaft seat 413 arranged on the connecting plate 1. Both ends of the swinging rod 411 are swingably connected to the first pin shaft seat 412 and the second pin shaft seat 413 respectively.
[0029] Mounting holes are provided at both ends of the mounting base plate 2. The mounting base plate 2 is fixedly mounted on the rear beam of the electric vehicle frame through the mounting holes provided at both ends and the matching bolts and nuts. The load-bearing mechanism 3 is detachably fixedly mounted on the top of the connecting plate 1. The shock-absorbing assembly 4 is fixedly connected between the connecting plate 1 and the mounting base plate 2. Four groups of buffer assemblies 5 arranged in a rectangular array are fixedly connected to the top of the mounting base plate 2. Each group of buffer assemblies 5 is fixedly connected to the bottom of the connecting plate 1. The slide rail 45 is fixedly connected to the top of the mounting base plate 2. The tops of the two groups of sliders 44 are fixedly connected with swinging members 41. The two groups of swinging members 41 are fixedly connected to the bottom of the connecting plate 1. The first spring 42 and the damper 43 are fixedly connected to the two groups of sliders 44 at both ends. The first pin shaft seat 412 is fixedly connected to the top of the slider 44. The second pin shaft seat 413 is fixedly connected to the bottom of the connecting plate 1.
[0030] Due to the arrangement of the connecting plate 1, the mounting base plate 2, the load-bearing mechanism 3, the shock-absorbing component 4 and the buffer component 5, the load-bearing device can be installed on the rear beam of the load-bearing electric vehicle frame through the mounting base plate 2. When the cargo needs to be fixed, the staff only needs to place the cargo on the load-bearing mechanism 3 to achieve fixation. Since the load-bearing mechanism 3 is detachably mounted on the top of the connecting plate 1, it is convenient for the staff to disassemble and repair the load-bearing mechanism 3. When the load-bearing electric vehicle equipped with the load-bearing device travels on a bumpy road section, the load-bearing mechanism 3 with the cargo placed thereon will produce continuous vibration. During the vibration process, the load-bearing mechanism 3 will cause the connecting plate 1 to simultaneously produce a certain force on the shock-absorbing component 4 and the buffer component 5, and compress the shock-absorbing component 4 and the buffer component 5. At this time, the shock-absorbing component 4 and the buffer component 5 in a compressed state will produce a certain buffering effect on the docking plate 1, so that the cargo placed on the load-bearing mechanism 3 can remain stable when encountering a bumpy road section, and thus can play a certain protective role for the cargo. Due to the arrangement of the swing member 41, the first spring 42, the damper 43, the slider 44, the slide rail 45, the swing rod 411, the first pin seat 412 and the second pin seat 413, when the connecting plate 1 compresses the shock absorbing assembly 4 and the buffer assembly 5 at the same time, the two sets of swing rods 411 will swing at a certain angle at the same time, and the two sets of swing rods 411 will push the corresponding two sets of sliders 44 to slide close to each other on the slide rail 45 during the swinging process. When the two sets of sliders 44 slide close to each other on the slide rail 45, they will compress the first spring 42 and the damper 43 at the same time. At this time, the first spring 42 and the damper 43 in the compressed state can produce a certain buffering effect on the connecting plate 1, and thus can play a certain protective role on the goods placed in the load-carrying mechanism 3.
[0031] like Figure 2 As shown, the load-carrying mechanism 3 includes a load-carrying frame 31 for placing goods, a mounting groove 32 arranged on the load-carrying frame 31, a fixing member 33 for fixing the mounting groove 32, and a positioning mechanism 34 for clamping goods. Two sets of positioning mechanisms 34 are symmetrically arranged on the load-carrying frame 31. The fixing member 33 is connected to the mounting groove 32 and the connecting plate 1.
[0032] The mounting groove 32 is fixedly connected to the bottom of the load frame 31. The fixing member 33 is preferably a bolt. Both ends of the mounting groove 32 are provided with a plurality of groups of fixing members 33 arranged in a linear array. Each group of fixing members 33 passes through the mounting groove 32 and is threadedly connected to the connecting plate 1. The load frame 31 is fixedly connected with two groups of positioning mechanisms 34 arranged symmetrically.
[0033] Due to the arrangement of the load rack 31, the mounting slot 32, the fixing member 33 and the positioning mechanism 34, and because the fixing member 33 passes through the mounting slot 32 and is threadedly connected to the connecting plate 1, it is convenient for the staff to disassemble and repair the load rack 31. When the goods need to be fixed, the staff only needs to place the goods in the load rack 31, and the two sets of positioning mechanisms 34 on the load rack 31 will firmly abut against the two sides of the goods, and the goods placed in the load rack 31 can be fixed at this time. The whole operation is simple and reliable, and it is convenient for the staff to operate.
[0034] like Figure 4 As shown, the positioning mechanism 34 includes a baffle 341 for abutting against the cargo, a second spring 342 for buffering the baffle 341, and a first telescopic rod 343 for limiting the second spring 342. The second spring 342 is arranged around the first telescopic rod 343. The telescopic end of the first telescopic rod 343 is connected to the baffle 341. The other end of the first telescopic rod 343 is connected to the load carrier 31.
[0035] The baffle plate 341 is provided with a plurality of groups of first telescopic rods 343 arranged in a linear array. A corresponding second spring 342 is arranged around the outer side of each group of first telescopic rods 343. The telescopic end of each group of first telescopic rods 343 is fixedly connected to the baffle plate 341. The other end of each group of first telescopic rods 343 is fixedly connected to the load frame 31. One end of each group of second springs 342 is fixedly connected to the baffle plate 341. The other end of each group of second springs 342 is fixedly connected to the load frame 31.
[0036] Due to the arrangement of the baffle plate 341, the second spring 342 and the first telescopic rod 343, when the cargo is placed on the load rack 31, the two sides of the cargo will respectively abut against the corresponding baffle plates 341, and a certain extrusion force will be generated on the two groups of baffle plates 341 at the same time, so that the two groups of baffle plates 341 compress the corresponding second springs 342 and the first telescopic rod 343 respectively, and the second spring 342 in a compressed state will generate a certain reaction force on the baffle plate 341, so that the two groups of baffle plates 341 can be firmly abutted against the two sides of the cargo, and the cargo can be fixed at this time. When the second spring 342 is in a compressed state, the first telescopic rod 343 can prevent the second spring 342 from being deformed, so it can play a certain protective role on the second spring 342.
[0037] like Figure 4 As shown, the positioning mechanism 34 further includes a rubber pad 344. The rubber pad 344 is arranged on the baffle 341.
[0038] A plurality of groups of rubber pads 344 arranged in a linear array are fixedly connected to the baffle 341 .
[0039] Due to the provision of the rubber pad 344, when the baffle 341 is against the goods, the rubber pad 344 on the baffle 341 will come into contact with the goods, thereby being able to provide a certain degree of protection for the goods.
[0040] like Figure 3 As shown, the buffer assembly 5 includes a third spring 51 for supporting the connecting plate 1 and a second telescopic rod 52 for limiting the third spring 51. The third spring 51 is arranged around the second telescopic rod 52. The telescopic end of the second telescopic rod 52 is connected to the connecting plate 1. The other end of the second telescopic rod 52 is connected to the mounting base plate 2.
[0041] The telescopic end of the second telescopic rod 52 is fixedly connected to the bottom of the connecting plate 1. The other end of the second telescopic rod 52 is fixedly connected to the top of the mounting base plate 2. One end of the third spring 51 is fixedly connected to the bottom of the connecting plate 1. The other end of the third spring 51 is fixedly connected to the top of the mounting base plate 2.
[0042] Due to the arrangement of the third spring 51 and the second telescopic rod 52, one end of the third spring 51 is fixedly connected to the connecting plate 1, and the other end of the third spring 51 is fixedly connected to the mounting base plate 2, so the load-carrying mechanism 3 with goods placed thereon will exert a certain pressure on the third spring 51 due to its own gravity, and compress the third spring 51 to a certain extent, and the third spring 51 in the compressed state can play a certain supporting role on the connecting plate 1. When the third spring 51 is in the compressed state, the second telescopic rod 52 can prevent the third spring 51 from being deformed, and thus can play a certain protective role on the third spring 51.
