[0002] In traditional technologies, most new energy vehicles directly install and fix the power battery on the vehicle body during the new vehicle production and manufacturing process, and the battery basically does not need to be disassembled during the subsequent vehicle use process.

[0003] Currently, some new energy vehicle models on the market adopt a battery swapping solution that can quickly disassemble and install the power battery and achieve rapid energy replenishment by replacing the power battery.

[0004] In the prior art, most power batteries are fixedly connected to the vehicle body bracket through a mounting bracket, and the mounting bracket and the vehicle body bracket are mostly fixedly connected by connection methods such as bolts or buckles. However, the disassembly process is relatively cumbersome and it is difficult to achieve the effect of rapid disassembly. Summary of the Utility Model

[0005] One of the purposes of the utility model is to provide a battery installation structure capable of swapping batteries to solve the problem that in the prior art, the mounting bracket and the vehicle body bracket are mostly fixedly connected by connection methods such as bolts or buckles, but the disassembly process is relatively cumbersome.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

The battery bracket is used to fix the battery, the mounting bracket is fixedly connected to the vehicle body, a locking member is provided on the battery bracket, a locking component is provided on the mounting bracket. When the locking member is locked with the locking component, the battery bracket and the mounting bracket are relatively fixed. When the locking member is unlocked from the locking component, the battery bracket and the mounting bracket can move relative to each other.

[0008] By setting the above structure, when installing the power battery, only need to lock the locking member and the locking component, then the battery bracket of the power battery can be fixedly connected to the mounting bracket. When removing the power battery, only need to unlock the locking member and the locking component, then the battery bracket of the power battery can be removed from under the mounting bracket, effectively improving the quick disassembly and assembly efficiency.

Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0041] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. The diagrams only show the components related to the present invention, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0042] As Figures 1 - 9 shown, this embodiment proposes a battery mounting structure that can be battery-swapped, including a battery bracket 1 and a mounting bracket 2. The battery bracket 1 is used to fix the battery, the mounting bracket 2 is fixedly connected to the vehicle body, a locking member is provided on the battery bracket 1, and a locking member is provided on the mounting bracket 2. When the locking member and the locking member are locked, the battery bracket 1 and the mounting bracket 2 are relatively fixed. When the locking member and the locking member are unlocked, the battery bracket 1 and the mounting bracket 2 can move relatively.

[0043] In this embodiment, the locking member includes a T-shaped lock 3, and the locking component includes a locking panel 4. The locking panel 4 is fixedly connected to the mounting bracket 2. A lock hole 41 is formed in the locking panel 4. The T-shaped lock 3 includes a lock core 31 and a lock base 32. The lock core 31 of the T-shaped lock 3 passes through the lock hole 41 and is locked to the bottom surface of the locking panel 4. Rotate the T-shaped lock 3 so that the lock core 31 of the T-shaped lock 3 rotates to be parallel to the lock hole 41. In this state, the T-shaped lock 3 and the locking panel 4 are in an unlocked state. Rotate the T-shaped lock 3 by 90° so that the lock core 31 of the T-shaped lock 3 rotates to intersect with the lock hole 41. In this state, the T-shaped lock 3 and the locking panel 4 are in a locked state. In some other embodiments, locking members and locking components such as latches and buckles can also be provided. Compared with conventional locks, the T-shaped lock 3 in this embodiment can not only ensure the locking strength between the battery bracket 1 and the mounting bracket 2, but also quickly and conveniently change the locking state. It should be noted that the lock hole 41 is a rectangular hole with dimensions of 67mm × 37mm and is provided at the center of the locking panel 4. The radii of the four corners of the lock hole 41 are 7mm.

[0044] In this embodiment, the length of the lock core 31 of the T-shaped lock 3 is 53mm, and the width is 25mm. The unilateral clearance between the lock core 31 of the T-shaped lock 3 and the lock hole 41 in the X direction is 4mm, and the unilateral clearance in the Y direction is 5mm, so as to ensure that the lock core 31 of the T-shaped lock 3 can smoothly pass through the lock hole 41 on the locking panel 4 within the tolerance range of the tooling positioning when replacing the battery.

[0045] In this embodiment, a connecting member 11 is provided on one side of the battery bracket 1 close to the locking panel 4. The connecting member 11 is integrally formed with the battery bracket 1. The lock base 32 of the T-shaped lock 3 is fixedly installed on the connecting member 11, and the bottom surface of the connecting member 11 abuts against the locking panel 4. The connecting member 11 can reduce the axial length of the lock core 31 of the T-shaped lock 3 and set the installation position on one side of the battery bracket 1, which is convenient for operating and rotating the T-shaped lock 3.

[0046] In this embodiment, a fastener 5 is provided between the locking panel 4 and the connecting member 11. The upper end of the fastener 5 is fixedly connected to the bottom surface of the connecting member 11 through a fixing bolt, and the lower end is attached to the top surface of the locking panel 4. When the bottom surface of the connecting member 11 is uneven, when the T-shaped lock 3 fixes the connecting member 11 and the mounting bracket 2, it will cause the battery bracket 1 to tilt, affecting the installation of the power battery. And setting the fastener 5 between the connecting member 11 and the locking panel 4 can adapt to the bottom surface of the connecting member 11 by the deformation of the fastener 5 itself or changing the shape of the fastener 5 itself, so as to ensure the smoothness of the connection between the connecting member 11 and the installation.

[0047] In this embodiment, the locking panel 4 is fixedly connected to the top surface of the mounting bracket 2. A reinforcing member 6 is fixedly connected inside the mounting bracket 2, and the reinforcing member 6 is attached to the bottom of the locking panel 4. The strength of the locking panel 4 is increased through the reinforcing member 6, thereby improving the locking stability between the T-shaped lock 3 and the locking panel 4.

[0048] In this embodiment, the reinforcing member 6 includes a reinforcing panel 61 and a reinforcing side panel 62. The reinforcing side panel 62 is fixedly connected to the reinforcing panel 61. The reinforcing panel 61 is attached to the locking panel 4, and the reinforcing side panel 62 is attached to the inner wall of the mounting bracket 2. In some other embodiments, the reinforcing member 6 can also be directly provided as a reinforcing rib. In this embodiment, by providing the reinforcing panel 61 and the reinforcing side panel 62, it is convenient to fix the reinforcing member 6 to the locking panel 4 and the mounting bracket 2. In this embodiment, a through hole 611 corresponding to the lock hole 41 is formed in the reinforcing panel 61. The lock core 31 of the T-shaped lock 3 passes through the lock hole 41 and the through hole 611 and is locked to the bottom surface of the reinforcing panel 61. The size of the through hole 611 is slightly larger than the size of the lock hole 41 to avoid the misalignment of the lock hole 41 of the locking panel 4 and the through hole 611 of the reinforcing panel 61 caused by the tolerance of the welding tooling, and to prevent the problem that the through hole size of the lock core 31 of the T-shaped lock 3 is insufficient. Specifically, the through hole 611 is a rectangular hole of 63 mm × 33 mm, and the radius of the four corners of the rectangular hole is 5 mm. Similarly, the through hole 611 is located in the central area of the reinforcing panel 61.

[0049] In this embodiment, the reinforcing panel 61 and the reinforcing side panel 62 are integrally formed. There are two reinforcing side panels 62, and the two reinforcing side panels 62 are symmetrically arranged on both sides of the reinforcing panel 61. The reinforcing panel 61 is fixedly connected to the locking panel 4 through six solder joints, and each of the two reinforcing side panels 62 is fixedly connected to the mounting bracket 2 through four solder joints. There is no fixation between the front and rear sides of the reinforcing panel 61 and the mounting bracket 2, leaving a redundant space to ensure that the position of the reinforcing member 6 can be adjusted when the reinforcing member 6 is welded to the mounting bracket 2 and the locking panel 4.

[0050] In this embodiment, the locking panel 4 and the mounting bracket 2 are integrally formed. A anti-rebound rib 21 is provided at the connection between the locking panel 4 and the mounting bracket 2, and a plurality of redundant slots 22 are formed between the locking panel 4 and the mounting bracket 2. The local stiffness of the locking panel 4 and the mounting bracket 2 is improved to prevent deformation.

[0051] In this embodiment, the mounting bracket 2 includes a plurality of side plates 23. The plurality of side plates 23 are integrally formed. A fixing ear 231 is provided at the bottom of the side plate 23. The fixing ear 231 is used for welding to the vehicle body to realize the fixed connection between the mounting bracket 2 and the vehicle body. The side plate 23 is inclined away from the T-shaped lock 3 from the end close to the locking panel 4 to the end of the fixing ear 231. By arranging the side plate 23 in an inclined manner, the lateral shear force of the mounting bracket 2 is enhanced, and the strength of the mounting bracket 2 is improved.

[0052] Working principle:

[0053] When removing the power battery, rotate the lock core 31 of the T-shaped lock 3 on the battery bracket 1 by 90°, so that the lock core 31 of the T-shaped lock 3 rotates to be parallel to the lock hole 41 and the through hole 611, and then remove the battery bracket 1 from the mounting bracket 2.

[0054] When installing the power battery, insert the lock core 31 of the T-shaped lock 3 into the lock hole 41 and the through hole 611, and then rotate the lock core 31 of the T-shaped lock 3 by 90°, so that the lock core 31 of the T-shaped lock 3 rotates to be staggered with the lock hole 41 and the through hole 611. The lock core 31 of the T-shaped lock 3 is in close contact with the bottom surface of the reinforcing panel 61, so that the battery bracket 1 is fixed to the mounting bracket 2, realizing the installation of the power battery.

[0055] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
