DETAILED DESCRIPTION
[0036] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways 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 illustrating the present invention, not for limiting the scope of protection of the present invention.
[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
[0038] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. Example
[0039] like Figures 1 to 4 As shown, a battery mounting bracket includes a tray fixing bracket 1, a battery mounting tray 2 and a limiting bracket 3. The tray fixing bracket 1 is used to be assembled and fixed with the rear section side plate 4 of the rear floor. The battery mounting tray 2 is detachably assembled on the tray fixing bracket 1 to match the battery mounting tray 2 of corresponding size according to the size of the battery 5. The limiting bracket 3 is assembled on the battery mounting tray 2 to limit the battery 5.
[0040] By setting a tray fixing bracket to be assembled and fixed with the rear section side plate of the rear floor, and providing a detachable battery mounting tray on the tray fixing bracket, the battery mounting tray of corresponding size can be matched according to the size of the battery, thereby improving the versatility of the battery mounting bracket and solving the problem that the existing battery mounting bracket is difficult to adapt to batteries of different specifications.
[0041] Among them, for the battery mounting bracket in the prior art, some battery mounting brackets adapt to batteries of different sizes by setting oblong holes or strip holes, but it is found in actual use that, on the one hand, the adaptation to batteries of different sizes by setting oblong holes or strip holes is limited, and on the other hand, the batteries assembled and fixed by oblong holes or strip holes are more or less loose after vehicle driving and vibration. Therefore, the present application solves the above problems by setting a detachable battery mounting tray on the tray fixing bracket, thereby matching the battery mounting tray according to the battery size.
[0042] In some embodiments, in order to achieve precise fine-tuning of the battery assembly limit, thereby effectively solving the tolerance problem generated in the battery manufacturing process and ensuring the accuracy and stability of battery assembly, the position of the limit bracket 3 relative to the battery mounting tray 2 is set to be adjustable.
[0043] In some embodiments, the relative position of the limiting bracket 3 and the battery mounting tray 2 is adjusted by setting the assembly hole 31 on the limiting bracket 3 to be a bar hole or an oblong hole.
[0044] In some embodiments, in order to ensure the stability of the assembly of the battery Y, a first limiting flange 21 is formed on the side of the battery mounting tray 2 opposite to the limiting bracket 3, so that the Y-direction limitation of the battery 5 is achieved through the mutual cooperation between the first limiting flange 21 and the limiting bracket 3.
[0045] Exemplarily, the limiting bracket 3 has a horizontal mounting portion and a vertical limiting portion, wherein the mounting portion is provided with an assembly hole 31 to achieve assembly and fixation with the battery mounting tray 2, and the limiting portion cooperates with the first limiting flange 21 to jointly achieve Y-direction limiting of the battery 5.
[0046] Exemplarily, a reinforcing rib 32 is further formed on the mounting portion of the limiting bracket 3 to enhance the rigidity of the limiting bracket 3 .
[0047] In some embodiments, in order to ensure the stability of the battery assembly in the Z direction, the first limiting flange 21 is designed to be a C-shaped structure, so as to be engaged and fixed with the protrusion 51 on the outer wall of the battery 5, thereby achieving the Z-direction limiting of the battery 5. The first limiting flange 21 is cleverly and simply designed to be a C-shaped structure, and is directly engaged with the protrusion 51 on the outer wall of the battery 5, which not only achieves the stable fixation of the battery 5 in the Z direction, but also breaks through the limitation of the height size of the battery 5 in the Z direction by the traditional fixing method. This design is both simple and efficient, and can flexibly adapt to batteries of different Z-direction sizes, greatly improving the adaptability and adjustability of battery fixation.
[0048] In some embodiments, in order to ensure the stability of the X-direction assembly of the battery, second limiting flanges 22 are formed on both sides adjacent to the battery mounting tray 2 and the limiting bracket 3, so that the X-direction limitation of the battery 5 is achieved through the mutual cooperation of the two second limiting flanges 22.
[0049] In some embodiments, in order to ensure the heat dissipation efficiency of the battery, the tray fixing bracket 1 is designed to be in a "X" shape, so that a heat dissipation space is formed between the tray fixing bracket 1 and the rear section side plate 4 of the rear floor. The top of the tray fixing bracket 1 is assembled and fixed to the battery mounting tray 2, and the two bottoms are used to be assembled and fixed to the rear section side plates 4 of the rear floor.
[0050] Exemplarily, in order to achieve lightweighting of the battery mounting bracket, a weight-reducing hole 11 is formed on the top of the tray fixing bracket 1. The weight-reducing hole 11 can also achieve a heat dissipation function, further improving the heat dissipation efficiency of the battery.
[0051] In some embodiments, in order to ensure the stability of the assembly of the battery mounting bracket itself, a connector 6 is used to assemble and fix the battery mounting tray 2 and the tray fixing bracket 1 together, and a connector 6 is used to assemble and fix the limiting bracket 3 and the battery mounting tray 2 together.
[0052] In some embodiments, in order to make the battery mounting tray 2 fit with the tray fixing bracket 1 during assembly to ensure the stability of the assembly of the battery mounting tray 2 and the tray fixing bracket 1, and at the same time to avoid the interference of the connecting member 6 with the assembly of the battery 5, a downwardly recessed installation plane 23 is formed on the battery mounting tray 2, so that the installation plane 23 fits with the tray fixing bracket 1, and the recessed space of the installation plane 23 can accommodate the upper end portion of the connecting member 6, thereby effectively avoiding the interference of the connecting member 6 with the assembly of the battery 5, and the non-recessed portion of the battery mounting tray 2 can form a space with the tray fixing bracket 1 for heat dissipation, thereby effectively improving the heat dissipation efficiency of the battery.
[0053] Exemplarily, the connecting member 6 is a mounting bolt, and a projection welding nut 7 is provided at the bolt mounting hole of the pallet fixing bracket 1 to facilitate the assembly of the mounting bolt and improve the assembly efficiency.
[0054] Exemplarily, the battery mounting tray 2 is similar to a rectangular structure, and the end of the battery mounting tray 2 close to the limiting bracket 3 is not provided with a flange structure to ensure the stability of the assembly of the battery mounting tray 2 and the limiting bracket 3. The end of the battery mounting tray 2 away from the limiting bracket 3 is formed with a first limiting flange 21, so that the Y-direction limitation of the battery 5 is achieved through the mutual cooperation of the first limiting flange 21 and the limiting bracket 3. The battery mounting tray 2 is formed with a second limiting flange 22 at the ends close to both sides of the limiting bracket 3, so that the X-direction limitation of the battery 5 is achieved through the mutual cooperation of the two second limiting flanges 22. The battery mounting tray 2 is also provided with an arrow to prevent mis-installation, and the direction of the arrow points to the front of the vehicle, which means that when the battery mounting bracket is installed on the vehicle, the arrow should point to the front of the vehicle.
[0055] In some embodiments, a mounting structure of a battery mounting bracket is also provided, including the battery mounting bracket in any of the above embodiments. In order to ensure the stability of the assembly of the battery mounting bracket and the rear floor, the tray fixing bracket 1 is fixedly installed on the rear side plate 4 of the rear floor.
[0056] Exemplarily, the tray fixing bracket 1 is fixed to the rear section side plate 4 of the rear floor by spot welding, riveting, screwing or the like.
[0057] In some embodiments, a vehicle is further provided, comprising the mounting structure of the battery mounting bracket in the above embodiments.
[0058] In actual use, the battery mounting bracket is first assembled on the vehicle body, that is, the tray fixing bracket 1 is first welded to the rear section side plate 4 of the rear floor of the vehicle body, and then the battery mounting tray 2 is fixedly assembled on the tray fixing bracket 1 by installing bolts. Then the battery is assembled on the battery mounting bracket, that is, the battery 5 is pushed into the battery mounting tray 2 from the inside of the vehicle to the outside of the vehicle (that is, it is pushed from the end of the battery mounting tray 2 close to the limiting bracket 3 to the direction of the first limiting flange 21), and the second limiting flanges 22 on both sides of the battery mounting tray 2 play an X-direction installation limiting role, and continue to push, so that the C-shaped first limiting flange 21 on the battery mounting tray 2 is engaged and fixed with the protrusion 51 on the outer wall of the battery 5, so as to achieve the Z-direction installation limiting role of the battery 5, and then according to the Y-direction size of the battery 5, the installation position of the limiting bracket 3 is adjusted, and the limiting bracket 3 is assembled and fixed on the battery mounting tray 2 by installing bolts, so as to achieve the Y-direction limiting role of the battery 5.
[0059] To sum up, the battery mounting bracket of the utility model is assembled and fixed with the rear side plate of the rear floor by setting a tray fixing bracket, and a detachable battery mounting tray is set on the tray fixing bracket, so that the battery mounting tray of corresponding size can be matched according to the size of the battery, thereby improving the versatility of the battery mounting bracket, reducing the production cost, and having the advantages of convenient assembly and high stability, meeting the development needs of the modern automobile industry, and having the advantages of simple structure, convenient assembly and low cost, and having promotion and application value in the field of automobile parts assembly technology.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
