Description

Technical Field

[0001] This utility model belongs to the technical field of battery protection devices, and in particular relates to a battery protection device for a tractor's AC power module. Background Technology

[0002] A tractor unit is a large truck or semi-trailer whose cab and trailer are towed by a tool. In other words, the cab can detach from the trailer to tow other trailers, and the trailer can also detach from the cab to be towed by other cabs. The cab with driving capability in front is called the tractor unit, and the trailer without driving capability behind is called the trailer. The trailer is towed by the tractor unit.

[0003] Existing battery swapping modules have several drawbacks when used for battery swapping. For example, if the battery is not securely fixed, it may fall and be damaged when the user handles it. Additionally, inserting the battery into the swapping cabinet requires force, which may cause the battery to impact the cabinet's inner wall and damage it. Therefore, we propose a battery protection device for tractor-mounted battery swapping modules. Utility Model Content

[0004] The purpose of this invention is to provide a battery protection device for a tractor's power exchange module, in order to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a battery protection device for a tractor's power exchange module, including a battery exchange cabinet and several battery bodies, and further comprising:

[0006] A plurality of placement slots are provided, all of which are located inside the battery swapping cabinet. A protective shell is fixedly installed in each of the plurality of placement slots. A battery body is inserted into each of the plurality of protective shells. A limit slot is provided in each of the plurality of protective shells. A limit strip is slidably installed in each of the plurality of limit slots. A plurality of fixing posts are fixedly installed on one side of each of the plurality of limit strips.

[0007] A plurality of driving components are located within a plurality of protective housings and are used to drive a plurality of fixed columns to slide.

[0008] A plurality of sliding grooves are provided, each of which is opened in a plurality of protective shells. Each of the plurality of sliding grooves is slidably installed with a sliding strip. Each of the plurality of sliding grooves is provided with a connecting post. Each of the plurality of connecting posts is rotatably installed with two connecting rods. The two ends of the plurality of connecting rods are slidably connected to the inner wall of the plurality of sliding grooves and the plurality of sliding strips, respectively.

[0009] A plurality of buffer components are located within a plurality of protective housings and are used to buffer the sliding of a plurality of sliding bars.

[0010] In this technical solution, when the battery body needs to be removed for use, the set drive component can drive several fixed posts to slide downwards, and the several fixed posts can drive the limit strip to slide downwards. When the limit strip is fully inserted into the limit groove, the battery body can be pulled out. Through the set buffer component, both sliding strips slide and slide away from the spring, and all four connecting rods are pulled and rotated.

[0011] After the fully charged battery is removed, the user needs to place the battery that needs charging into the protective case for charging. When the battery is inserted into the protective case, it will press against the arc surface of the limiting strip. The limiting strip will slide downwards under pressure, and then the tail of the battery will contact the two sliding strips. The battery will then press against the two sliding strips and slide. The buffer component reduces the impact stress caused by the battery and ensures that the two sliding strips slide stably, ensuring that the battery can be smoothly inserted into the protective case without being damaged by impact. When the battery is fully inside the protective case, the limiting strip slides upwards and resets through the driving component. The limiting strip can fix the position of the battery and ensure that the battery will not move after it is fixed.

[0012] In the above technical solution, the driving component further includes:

[0013] A rectangular plate is slidably installed in a limiting groove. A plurality of guide grooves are provided in the rectangular plate. One end of a plurality of fixed posts extends into the plurality of guide grooves, and the plurality of fixed posts are slidably connected to the plurality of guide grooves.

[0014] Two guide rods are fixedly mounted on a rectangular plate, and each guide rod is fitted with a tension spring.

[0015] In this technical solution, when the battery body needs to be removed for use, the rectangular plate is first pulled to slide. The rectangular plate drives the two guide rods to slide, and at the same time, the two tension springs are stretched. The rectangular plate drives the fixed posts to slide downward through the several guide grooves. The fixed posts drive the limiting strip to slide downward. When the limiting strip is completely inserted into the limiting groove, the battery body can be pulled out.

[0016] In the above technical solution, the buffer component further includes:

[0017] Two damping rods are fixedly installed in the sliding groove, one end of each damping rod is fixedly connected to the sliding bar, and a spring is sleeved on each damping rod.

[0018] In this technical solution, the tail of the battery body contacts two sliding strips. Then, the battery body squeezes the two sliding strips to slide. At the same time, the four springs and four damping rods are squeezed and contracted, and the four connecting rods are also squeezed and rotated. The four connecting rods slide on the two sliding grooves and the two sliding strips respectively. The four connecting rods and the two springs can reduce the impact stress caused by the battery body and ensure that the two sliding strips slide stably, ensuring that the battery body can be smoothly inserted into the protective shell without being damaged by impact.

[0019] In the above technical solution, further, the two ends of the plurality of tension springs are respectively welded to the inner walls of the plurality of limiting grooves and the rectangular plate, and the two ends of the plurality of springs are respectively welded to the inner walls of the plurality of sliding grooves and the plurality of sliding strips.

[0020] In this technical solution, it is ensured that several tension springs and several springs can be used stably.

[0021] In the above technical solution, furthermore, the fixed columns and guide rods are slidably connected to the limiting grooves respectively.

[0022] In this technical solution, it is ensured that several fixed columns and several guide rods can slide within several limiting grooves respectively.

[0023] In the above technical solution, furthermore, shock-absorbing rubber pads are fixedly installed on each of the sliding bars, and the shock-absorbing rubber pads are in close contact with the battery body.

[0024] In this technical solution, the shock-absorbing rubber pads can protect the tail of the battery body, ensuring that the tail of the battery body will not be damaged by impact.

[0025] Furthermore, in the above technical solution, the tops of several of the limiting strips are all arc-shaped.

[0026] In this technical solution, it is ensured that the battery body will squeeze the arc surface on the limiting strip, and the limiting strip will slide downward under the pressure.

[0027] The beneficial effects of this utility model are:

[0028] 1. The battery protection device for the tractor's power exchange module requires that after the fully charged battery is removed, the user needs to place the battery that needs to be charged into the protective housing for charging. When the battery is inserted into the protective housing, it will press against the arc surface of the limiting strip. The limiting strip will slide downward under pressure. After the battery is fully inside the protective housing, the limiting strip will slide upward and reset through the set drive component. The limiting strip can fix the position of the battery and ensure that the battery will not be displaced after it is fixed.

[0029] 2. The battery protection device for the tractor's power exchange module involves the rear of the battery body contacting two sliding strips. The battery body then presses against the two sliding strips to slide. The buffer component reduces the impact stress caused by the battery body and ensures that the two sliding strips slide stably, ensuring that the battery body can be smoothly inserted into the protective shell without being damaged by impact.

A limit strip 6 is slidably installed in each of the several limit strips 6. Several fixing posts 7 are fixedly installed on one side of each of the several limit strips 6.

[0045] Several driving components are located inside several protective shells 3, and are used to drive several fixed columns 7 to slide.

[0046] A plurality of sliding grooves 8 are respectively opened in a plurality of protective shells 3. Sliding strips 9 are slidably installed in each of the plurality of sliding grooves 8. Connecting posts 14 are provided in each of the plurality of sliding grooves 8. Two connecting rods 15 are rotatably installed on each of the plurality of connecting posts 14. The two ends of the plurality of connecting rods 15 are slidably connected to the inner wall of the plurality of sliding grooves 8 and the plurality of sliding strips 9 respectively.

[0047] Several buffer components are located inside several protective shells 3, and are used to buffer the sliding of several sliding bars 9.

[0048] When the battery body 4 needs to be removed for use, the driving component can drive several fixed posts 7 to slide downwards, and the fixed posts 7 can drive the limiting strip 6 to slide downwards. When the limiting strip 6 is fully inserted into the limiting groove 5, the battery body 4 can be pulled out. Through the buffer component, both sliding strips 9 slide and slide away from the spring 17, and all four connecting rods 15 are pulled and rotated.

[0049] After the fully charged battery body 4 is removed, the user needs to place the battery body 4 that needs to be charged into the protective shell 3 for charging. When the battery body 4 that needs to be charged is inserted into the protective shell 3, the battery body 4 will press against the arc surface of the limiting strip 6. The limiting strip 6 will slide downward under pressure. Then, the tail of the battery body 4 will contact the two sliding strips 9.

[0052] Two guide rods 12 are fixedly installed on the rectangular plate 10, and each guide rod 12 is fitted with a tension spring 13.

[0053] When the battery body 4 needs to be removed for use, first pull the rectangular plate 10 to slide. The rectangular plate 10 drives the two guide rods 12 to slide, and at the same time the two tension springs 13 are stretched. The rectangular plate 10 drives the fixed posts 7 to slide downward through the several guide grooves 11. The fixed posts 7 drive the limiting strip 6 to slide downward. When the limiting strip 6 is completely inserted into the limiting groove 5, the battery body 4 can be pulled out.

[0054] In this embodiment, the buffer component includes:

[0055] Two damping rods 16 are fixedly installed in the sliding groove 8. One end of each damping rod 16 is fixedly connected to the sliding strip 9. A spring 17 is sleeved on each damping rod 16.

[0056] In this process, the tail of the battery body 4 contacts the two sliding strips 9. Then, the battery body 4 presses the two sliding strips 9 to slide. At the same time, the four springs 17 and the four damping rods 16 are compressed and contracted. The four connecting rods 15 are also compressed and rotate. The four connecting rods 15 slide on the two sliding grooves 8 and the two sliding strips 9 respectively. The four connecting rods 15 and the two springs 17 can reduce the impact stress caused by the battery body 4 and ensure that the two sliding strips 9 slide stably, ensuring that the battery body 4 can be smoothly inserted into the protective shell 3 without being damaged by impact.

[0065] Example 4:

[0066] This embodiment provides a battery protection device for a tractor's power exchange module, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] In this embodiment, shock-absorbing rubber pads 18 are fixedly installed on several sliding bars 9, and the several shock-absorbing rubber pads 18 are in close contact with the battery body 4.

[0068] The shock-absorbing rubber pad 18 can protect the tail of the battery body 4, ensuring that the tail of the battery body 4 will not be damaged by impact.

[0069] Example 5:

[0070] This embodiment provides a battery protection device for a tractor's power exchange module, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] In this embodiment, the tops of several limiting strips 6 are all arc-shaped.

[0072] Specifically, the battery body 4 is ensured to press against the arc surface of the limiting strip 6, causing the limiting strip 6 to slide downwards under pressure.

[0073] Working principle: When the battery body 4 needs to be removed for use, first pull the rectangular plate 10 to slide. The rectangular plate 10 drives the two guide rods 12 to slide, and at the same time the two tension springs 13 are stretched. The rectangular plate 10 drives the fixed posts 7 to slide downward through the several guide grooves 11. The fixed posts 7 drive the limiting strip 6 to slide downward. When the limiting strip 6 is completely inserted into the limiting groove 5, the battery body 4 can be pulled out. At the same time, under the action of the rebound force of the four springs 17, the two sliding strips 9 slide and slide away from the springs 17. The four damping rods 16 are stretched and return to their original positions. At the same time, the four connecting rods 15 are rotated.

[0074] After the fully charged battery body 4 is removed, the user needs to place the battery body 4 that needs to be charged into the protective shell 3 for charging. When the battery body 4 that needs to be charged is inserted into the protective shell 3, the battery body 4 will press against the arc surface on the limiting strip 6. The limiting strip 6 will slide downward under pressure. Through the above operation, the rectangular plate 10 can be moved away from the tension spring 13. At the same time, the two tension springs 13 are stretched. Then, the tail of the battery body 4 contacts the two shock-absorbing rubber pads 18. Then, the battery body 4 presses against the two sliding strips 9 to slide. At the same time, the four springs 17 and the four damping rods 16 are compressed and contracted. The four connecting rods 15 are also compressed. The pressure causes rotation, and the four connecting rods 15 slide on the two sliding grooves 8 and the two sliding bars 9 respectively. The four connecting rods 15 and the two springs 17 can reduce the impact stress caused by the battery body 4 and ensure that the two sliding bars 9 slide stably, ensuring that the battery body 4 can be smoothly inserted into the protective shell 3 without being damaged by impact. When the battery body 4 is completely inserted into the protective shell 3, under the action of the tension of the two tension springs 13, the rectangular plate 10 slides towards the tension springs 13, and then the limiting strip 6 slides upward and resets. The limiting strip 6 can fix the position of the battery body 4, ensuring that the battery body 4 will not be displaced after it is fixed.

[0075] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
