[0025] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a stable battery fixing structure, which includes a battery box 1, a bottom cover 2, a tailgate 3, and a box body 4 equipped with a vehicle system. In this embodiment, the battery fixing structure is described in the orientation shown in the accompanying drawings.
[0026] Specifically, the bottom cover 2 and tailgate 3 are fixedly connected to adjacent sides of the case 4. The edge of the tailgate 3 near the bottom cover 2 is provided with a first flange 31 and a second flange 32 that curve toward the bottom cover 2. The height difference between the first flange 31 and the second flange 32 forms a gap 33. The edge of the bottom cover 2 is locked within the gap 33, so that the side of the bottom cover 2 facing away from the case 4 abuts the bottom of the first flange 31, and the side of the bottom cover 2 facing the case 4 abuts the top of the second flange 32. The battery compartment 1, which contains batteries, is fixed to the side of the bottom cover 2 facing away from the case 4 via screws 5. The batteries added to the vehicle system are then assembled on the case 4.
[0027] When assembling the battery fixing structure, first install the bottom cover 2 and the tailgate 3 on adjacent sides of the box body 4 to seal the box body 4. An edge of the bottom cover 2 is inserted into the gap 33 formed by the first flange 31 and the second flange 32, so that the edge of the bottom cover 2 is locked and confined in the gap 33. The first flange 31 and the second flange 32 respectively abut the two opposing sides of the bottom cover 2, providing vertical support for the bottom cover 2. The bottom cover 2 is then secured with screws 5, which improves the stability of its installation. Since the battery box 1 containing the batteries is fixedly connected to the bottom cover 2, optimizing the tailgate 3 of the vehicle structure not only improves the assembly stability of the bottom cover 2, but also improves the installation stability of the battery box 1.
[0028] Furthermore, the first and second flanges 31, 32 are bent at right angles, and the bends are arc-shaped. The edge of the bottom cover 2 facing away from the box body 4 has a chamfer 21. The first and second flanges 31, 32 are bent at right angles to better clamp and support the edge of the bottom cover 2. Simultaneously, the chamfer 21 is designed on the edge of the bottom cover 2 near the rear baffle 3 to facilitate insertion into the gap 33 between the first and second flanges 31, 32. This allows for more precise positioning during installation and a close fit between the edge of the bottom cover 2 and the first and second flanges 31, 32, enhancing the ease of assembly of the battery fixing structure.
[0029] In one embodiment, the edge of the rear baffle 3 facing away from the bottom cover 2 is provided with a third flange 34 that curves toward the case 4 at a right angle. During assembly, the third flange 34 engages the side of the case 4 facing away from the bottom cover 2, further enhancing the stability of the rear baffle 3. Furthermore, the third flange 34, in conjunction with the first and second flanges 31 and 32, enhances support for the bottom cover 2, thereby improving the stability of the battery compartment 1.
[0030] In one specific embodiment, first limiting portions 41 extend from both sides of the housing 4 toward the rear baffle 3. The rear baffle 3 is provided with first limiting grooves 35 whose shape and position correspond to those of the first limiting portions 41. When the rear baffle 3 is installed, the first limiting grooves 35 engage with the first limiting portions 41 to vertically limit the rear baffle 3. Providing two sets of first limiting portions 41 and first limiting grooves 35 further enhances the stability of the installation of the rear baffle 3. Furthermore, after the rear baffle 3 is secured, the ends of the rear baffle 3 near the first limiting portions 41 abut against the sidewalls of the housing 4 to horizontally limit the rear baffle 3. Furthermore, the side of the rear baffle 3 facing away from the housing 4 is aligned vertically with the edge of the sidewall of the housing 4.
[0031] In one embodiment, the rear baffle 3 is provided with several mounting holes 36 along its edge. Screws 5 penetrate through these holes and threadably engage the housing 4, thereby securing the rear baffle 3 to the housing 4. Because the first flange 31 and the second flange 32 cooperate to position the edge of the bottom cover 2, screws 5 are no longer required to secure the rear baffle 3 to the bottom cover 2. This reduces the number of screws 5 and saves assembly costs and steps. Furthermore, the rear baffle 3 is provided with several through-holes 37 for accessing the internal structure of the housing 4, thereby preventing interference with the installation of the internal structure.
[0032] In one embodiment, the battery compartment 1 has an opening 11 on one side for inserting or removing batteries, and a sealing plate 22 extends from the side of the bottom cover 2 away from the housing 4 to seal the battery compartment 1. When the battery compartment 1 is secured to the bottom cover 2, the opening 11 of the battery compartment 1 abuts against the sealing plate 22, thereby sealing the battery compartment 1.
[0033] Furthermore, a support portion 23 is provided on the side of the closing plate 22 away from the battery compartment 1. The support portion 23 connects the closing plate 22 and the bottom cover 2, thereby supporting and stabilizing the closing plate 22 and improving the stability of the closing plate 22. At the same time, second limiting grooves 221 are respectively provided on both sides of the closing plate 22 in the horizontal direction, and corresponding second limiting portions 12 are respectively provided on the side of the battery compartment 1 close to the closing plate 22. When the battery compartment 1 is fixed to the bottom cover 2, the two second limiting portions 12 are respectively inserted and limited in the two second limiting grooves 221, thereby limiting the battery compartment 1 in the horizontal and vertical directions, further improving the stability of the battery compartment 1 installation.
[0034] In a specific embodiment, the bottom cover 2 is further provided with a plurality of heat dissipation holes 24, which connect the interior of the box body 4 with the external environment, thereby dissipating heat for the operation of the vehicle system and other structures inside the box body 4, and dissipating heat for the operation of the battery.
[0035] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
