[0042] This utility model proposes a battery mounting mechanism.

[0043] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the battery mounting mechanism includes:

[0044] The battery compartment 100 has a receiving cavity with an opening on one side, which is used to hold the battery module 200.

[0045] A door cover 300 is located at the opening and is movably connected to the battery compartment 100 to open or close the opening; and

[0046] A snap-fit ​​assembly 400 is provided on the side of the battery compartment 100 where the opening is provided. The snap-fit ​​assembly 400 is movably connected to the battery compartment 100 so as to lock or release the door cover 300 when the door cover 300 is fastened at the opening.

[0047] In the technical solution of this utility model, the battery installation mechanism includes a battery compartment 100, which houses a battery module 200. The battery compartment 100 has an opening, through which the battery module 200 is inserted or removed. A door cover 300 is movably disposed at the opening, and the door cover 300 is movably connected to the battery compartment 100 at the opening to open or close the opening. A snap-fit ​​assembly 400 is disposed on the battery compartment 100 and is used to engage with the door cover 300. The snap-fit ​​assembly 400 is movably connected to the battery compartment 100 to have a first position and a second position on the battery compartment 100. In the first position, the snap-fit ​​assembly 400 is close to the door cover 300 and locks the door cover 300 when it is fastened to the opening. In the second position, the snap-fit ​​assembly... The component 400 is moved away from the door cover 300 to release the door cover 300, allowing the door cover 300 to move freely at the opening to open or close the opening. When it is necessary to remove the battery module 200 from the battery compartment 100, the snap fastener assembly 400 is moved to release the door cover 300. At this time, the door cover 300 is moved, and the opening is opened to remove the battery module 200 from the accommodating cavity. Compared with the existing technical solution that uses screws for connection, which is inconvenient to install and remove, this solution can release the door cover 300 simply by moving the snap fastener assembly 400. This simplifies the operation steps and allows for quick and easy removal and placement of the battery module 200. The structure of this solution is easy to disassemble, which can avoid damage to the battery module 200 and the opening of the battery compartment 100 during disassembly.

[0048] Specifically, the battery installation mechanism includes a battery compartment 100. The external shape of the battery compartment 100 is not limited. The internal accommodating cavity is preferably fitted with the outer wall of the battery module 200. In one embodiment, the battery compartment 100 includes a compartment body 110 and a cover plate 120. The compartment body 110 includes a bottom plate, two side plates 111, a rear baffle, and a front baffle 112. The bottom plate, the two side plates 111, the front baffle 112, and the rear baffle form an upper open accommodating cavity. The cover plate 120 is disposed on the top and opposite to the bottom plate. The cover plate 120 is mounted on the side plates 111. The length of the front baffle 112 is greater than the length distance between the two side plates 111, that is, the two sides of the front baffle 112 protrude from the side plates 111. The opening is disposed at the front baffle 112 and communicates with the accommodating cavity.

[0049] A door cover 300 is movably disposed at the opening of the battery compartment 100. A snap fastener assembly 400 is disposed on the side of the battery compartment 100 with the opening and is used to lock the door cover 300. In one embodiment, the door cover 300 can slide with the battery compartment 100, such as sliding horizontally or vertically on the side of the battery compartment 100 with the opening, to open or close the opening. The snap fastener assembly 400 can be hinged with the battery compartment 100 and has a hook portion at the end away from the battery compartment 100. The hook portion is used to engage the door cover 300. When it is necessary to close the opening, push the door cover 300 to move until the door cover 300 closes the opening. At this time, rotate the snap fastener assembly 400 so that the hook portion engages with the door cover 300. At this time, the door cover 300 cannot move and the opening remains closed. When it is necessary to open the opening, rotate the snap fastener assembly 400 so that the hook portion disengages from the door cover 300, move the door cover 300 to expose the opening, and take out the battery module 200 from the opening, simplifying the operation steps.

[0050] In one embodiment, the battery module 200 includes a housing and multiple batteries. The multiple batteries are disposed inside the housing. The housing can be made of a high-strength, flame-retardant material, such as aluminum alloy or engineering plastic, which has good mechanical strength. This is not limited here. It can effectively protect the internal batteries from external vibration during use. The multiple internal batteries can be connected in series, in parallel, or in a series-parallel combination, depending on the voltage and capacity requirements required by the actual application. This is not limited here.

[0051] In an embodiment of this utility model, the door cover 300 is rotatably connected to the battery compartment 100 via at least one hinge. The door cover 300 is provided with at least one limiting hole 310 on the side away from the hinge. The snap fastener assembly 400 is slidably connected to the battery compartment 100. The snap fastener assembly 400 slides along a first direction to insert into the limiting hole 310 to lock the door cover 300 or to release the door cover 300 away from the limiting hole 310.

[0052] Please refer to Figure 4 , Figure 5 and Figure 6The door cover 300 has at least one hinge on one side, which is screwed onto the battery compartment 100. A pivot 320 is provided, with its two ends installed on both ends of one side of the door cover 300, passing through the hinge and rotatably connected to it, allowing the door cover 300 to rotate relative to the battery compartment 100. A limit hole 310 is provided at the end of the door cover 300 away from the hinge. A snap-fit ​​assembly 400 is inserted into the limit hole 310 to prevent the door cover 300 from rotating outward to open the door cover 300. Specifically, the snap-fit ​​assembly 400 is configured to slide with the battery compartment 100, and the snap-fit ​​assembly 400 slides in a first direction, which is the direction between the side of the door cover 300 with the hinge and the side away from the hinge. When the door cover 300 is rotated to the closed opening, the sliding snap fastener assembly 400 is inserted into the limiting hole 310, thereby locking the door cover 300 and preventing it from being rotated open. This ensures the stability of the battery module 200 within the accommodating cavity and prevents the battery module 200 from shifting or detaching due to vibration. If you want to open the door cover 300, slide the snap fastener assembly 400 in the opposite direction along the first direction, moving the snap fastener assembly 400 away from the limiting hole 310, thereby releasing the door cover 300. At this point, the door cover 300 can be rotated and opened. Locking and releasing the door cover 300 can be achieved by sliding the snap fastener assembly 400. The operation steps are simple and easy to implement.

[0053] In an embodiment of this utility model, the battery compartment 100 is provided with an installation groove 101 on the side with the opening, and a limiting part 130 is provided on the side of the installation groove 101 away from the door cover 300.

[0054] The battery mounting mechanism also includes an elastic element 500, which is disposed in the mounting groove 101. One end of the elastic element 500 abuts against the limiting part 130, and the other end is connected to the snap fastener assembly 400. The elastic element 500 is in a compressed state so that the snap fastener assembly 400 tends to move toward the limiting hole 310.

[0055] Please refer to Figure 4On the front baffle of the battery compartment 100, a mounting groove 101 is provided on one side of the front baffle 112. The mounting groove 101 is lower than the surface of the front baffle 112. The snap-fit ​​assembly 400 slides within the mounting groove 101. An elastic element 500 and a limiting part 130 are provided along the inner edge of the mounting groove 101. The limiting part 130 is located on the side of the mounting groove 101 away from the door cover 300. The elastic element 500 extends in a first direction. The snap-fit ​​assembly 400 is connected to the limiting part 130 through the elastic element 500. When it is necessary to release the door cover 300, the snap-fit ​​assembly 400 is pushed in the first direction, that is, in the direction away from the door cover 300. At this time, the elastic element 500 is compressed, the snap-fit ​​assembly 400 moves away from the limiting hole 310, and the door cover 300 is released. Then the door cover 300 can be opened. If it is not needed, it can be closed immediately. When closing the door cover 300, the snap fastener assembly 400 can be loosened to allow it to spring back, avoiding continuous force. When it is necessary to rotate the door cover 300 to close and lock it to prevent it from opening, push the snap fastener assembly 400 towards the limiting part 130 in the first direction, so that the snap fastener assembly 400 moves away from the door cover 300 to avoid blocking the closing of the door cover 300. After the door cover 300 is closed, release the snap fastener assembly 400. Under the springback of the elastic element 500, the elastic element 500 drives the snap fastener assembly 400 to slide in the mounting groove 101 in the first direction towards the door cover 300. The snap fastener assembly 400 is inserted into the limiting hole 310 to prevent the door cover 300 from rotating and opening. The setting of the elastic element 500 allows the snap fastener assembly 400 to automatically spring back to the limiting hole 310 to lock the door cover 300. The operation is simple and easy to implement.

[0056] In one embodiment, two limiting parts 130 and elastic members 500 are provided. The two elastic members 500 are respectively provided at both ends of the snap fastener assembly 400 on the side away from the door cover 300. The limiting parts 130 are correspondingly provided, which can make the snap fastener assembly 400 move more stably and prevent the snap fastener assembly 400 from deflecting when the elastic members 500 rebound.

[0057] In an embodiment of this utility model, the limiting part 130 has a sliding groove 131 extending along a first direction, the sliding groove 131 communicating with the mounting groove 101, and the snap-fit ​​assembly 400 includes:

[0058] The snap-fit ​​body 410 is slidably disposed within the mounting groove 101;

[0059] The snap fastener 420 is located at one end of the snap fastener body 410 near the door cover 300, and is used to be inserted into the limiting hole 310.

[0060] The guide post 430 is located at the end of the snap fastener body 410 away from the door cover 300. The elastic element 500 is sleeved on the guide post 430, and the guide post 430 is inserted into the slide groove 131 and slides within the slide groove 131.

[0061] Please refer to Figure 4 and Figure 5 Within the mounting groove 101, a movable space is formed between the two limiting parts 130. A sliding groove 131 extending in a first direction is provided on the limiting part 130, and the sliding groove 131 communicates with the mounting groove 101. The snap fastener assembly 400 includes a snap fastener body 410, a snap fastener 420, and a guide post 430. The snap fastener body 410 includes a first locking part 411 and a first locking part 412. The first locking part 411 is located near the door cover 300, and the first locking part 412 is located away from the door cover 300. The first locking part 411 and the first locking part 412 are integrally formed. The length of the first locking part 411 is greater than the length of the first locking part 412, and the length of the first locking part 412 is less than or equal to the distance between the two limiting parts 130, so that the first locking part 412 can slide within the movable space. Two elastic members 500 are provided on the side of the first locking part 411 where the first locking part 412 is installed, and the two elastic members 500 are respectively located on the first locking part 411. On both sides of part 412, guide posts 430 are also provided on the side of the first latch part 411 facing the limiting part 130. Elastic members 500 are sleeved outside the guide posts 430. The guide posts 430 are inserted into the slide groove 131. When the snap fastening assembly 400 moves in the first direction, the guide posts 430 slide in the slide groove 131, and the first latch part 412 slides in the movable space. The guide posts 430 provide guidance for the movement of the snap fastening assembly 400, and prevent it from shifting during the movement and failing to lock the door cover 300. At least one buckle 420 is provided on the side of the first latch part 411 facing the door cover 300. The position of each buckle 420 corresponds to the position of the limiting hole 310. When the door cover 300 is fastened at the opening, the elastic members 500 rebound and drive the snap fastening body 410 to move toward the door cover 300, so that the buckle 420 is inserted into the limiting hole 310, which can prevent the door cover 300 from being rotated outward to open.

[0062] In one embodiment, the snap fastener assembly 400 further includes a force-applying portion 440, which protrudes from the snap fastener body 410 on the side away from the mounting groove 101.

[0063] Please refer to Figure 4 and Figure 5 A force-applying part 440 is provided on the side of the first card part 412 away from the mounting groove 101. The force-applying part 440 is protruding so that when the door cover 300 needs to be released, the force-applying part 440 can be pushed directly to the right (in the direction shown in the figure) so that the buckle body 410 moves to the right and releases the door cover 300. The force-applying part 440 is designed to facilitate the operation with leverage, making it easier to release the door cover 300.

[0064] In one embodiment, the force-applying part 440 is configured as a ring structure, and the side away from the door cover 300 is higher than other positions. In another embodiment, the force-applying part 440 can be configured as a straight structure, and there is no limitation here.

[0065] In an embodiment of this utility model, the battery mounting mechanism further includes a pressure plate 600, which is located on the side of the battery compartment 100 where the cover 300 is located. The pressure plate 600 has a mounting hole 610, and the force-applying part 440 protrudes from the mounting hole 610 and slides in the mounting hole 610 along a first direction.

[0066] Please refer to Figure 1 and Figure 3 A slot is provided on the outer periphery of the position where the mounting slot 101 is located on the front baffle 112. The slot is lower than the surface of the front baffle 112 but higher than the mounting slot 101. The pressure plate 600 is installed in the slot by screws. The slot is designed so that the pressure plate 600 does not protrude from the battery compartment 100. Specifically, four screws are provided, which are respectively set at the four corners of the pressure plate 600 to fix the pressure plate 600 to the battery compartment 100. The pressure plate 600 has a mounting hole 610 in the middle. The force-applying part 440 passes through the mounting hole 610 and slides in the mounting hole 610. That is, the setting of the pressure plate 600 provides sliding space for the force-applying part 440. This not only prevents the buckle assembly 400 from falling out of the mounting slot 101, but also improves the overall aesthetics by covering the inside of the mounting slot 101 without affecting operation.

[0067] In an embodiment of this utility model, a sealing ring 330 is provided on the side of the door cover 300 facing the opening. The sealing ring 330 is used to seal the connection between the opening and the door cover 300. The sealing ring 330 is usually made of a material with good elasticity, such as rubber. The sealing ring 330 is adapted to the periphery of the opening. When the door cover 300 is closed, the sealing ring 330 can form a barrier for the opening, enhance the sealing effect, and play a role in waterproofing and dustproofing, protecting the internal battery module 200 from water corrosion. In addition, it can also reduce or avoid the entry of dust, which may affect the operation of the internal battery module 200 and ensure long-term stability.

[0068] In one embodiment, at least one silicone pad 340 is provided on the side of the door cover 300 facing the opening. When the door cover 300 is closed, the silicone pad 340 will squeeze the battery module 200, so that the battery module 200 is kept in a tight state in the accommodating cavity, so as to prevent the battery module 200 from becoming loose in the event of movement or vibration.

[0069] In embodiments of this utility model, such as Figure 7 As shown, a pull part 210 is provided at one end of the battery module 200 near the opening, so that when the door cover 300 is opened, the battery module 200 can be taken out of the accommodating cavity by applying force to the pull part 210 without the need for additional tools, saving time, simplifying the operation steps, reducing the difficulty of operation, and avoiding damage to the battery module 200 due to improper force.

[0070] Please refer to Figure 2 and Figure 3 In an embodiment of this utility model, a through hole is provided at the end of the battery compartment 100 away from the door cover 300. The battery mounting mechanism also includes a blade connector 700, which passes through the through hole and connects to the battery module 200. That is, the through hole is provided on the rear panel. The through hole facilitates the connection between the blade connector 700 and the battery module 200. It does not occupy the internal space of the battery compartment 100 and can ensure a stable connection between the battery module 200 and the blade connector 700.

[0071] In an embodiment of this utility model, the battery mounting mechanism further includes a slide rail 140, which is disposed inside the battery compartment 100 and slidably connected to the bottom of the battery module 200. The slide rail 140 is made of a smooth and wear-resistant material, such as POM (polyoxymethylene), which can effectively reduce the resistance of the battery module 200 during the sliding process, making the battery module 200 easier to put in and take out. In addition, POM material has good wear resistance, which can ensure that the slide rail 140 can still maintain stable performance under long-term use, avoid wear and tear that may cause jamming or loosening, extend service life, and reduce maintenance costs.

[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
