Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides a new energy battery installation structure for commercial vehicles, which optimizes the spatial layout, improves space utilization, expands the capacity of high-voltage batteries, and enhances the overall vehicle range.

[0031] Please refer to this as well. Figures 1 to 5 The commercial vehicle new energy battery installation structure provided by this utility model includes a frame body 10, a left connecting bracket 20, a right connecting bracket 30, a battery mounting bracket 40, and a controller bracket 60.

[0032] The left connecting bracket 20 and the right connecting bracket 30 are fixed on the left and right sides of the frame body 10, respectively. The left connecting bracket 20 and the right connecting bracket 30 are used to connect with the frame 70. The frame 70 is a frame structure that spans the front and rear axles of the car. It is the core support base of the car and can withstand the weight of the vehicle itself, the load and the impact of the road, so as to ensure the structural stability.

[0033] A battery mounting bracket 40 is fixedly mounted on the frame body 10 for mounting a battery 80. The battery mounting bracket 40 includes a base plate 41 and several connecting posts 42 fixedly mounted on the base plate 41. Limiting members 43 are sleeved and fixedly mounted on the connecting posts 42. The bottom surface of the limiting member 43 is used to abut against the top of the battery 80 to limit the position of the battery 80. Specifically, the limiting member 43 is a limiting plate, and nuts can be threadedly connected to the connecting posts 42. The nuts are located on the upper and lower sides of the limiting member 43, and the position of the limiting member 43 is fixed by the abutment of the limiting member 43 by the nuts.

[0034] The controller bracket 60 is fixedly mounted on the top of the frame body 10, near the right connecting bracket 30. The controller bracket 60 is used to install the vehicle controller.

[0035] The frame body 10 is fixedly installed on the top of the vehicle frame 70 via the left connecting bracket 20 and the right connecting bracket 30. The battery mounting bracket 40 is fixedly installed on the frame body 10. The battery 80 can be installed on the base plate 41 of the battery mounting bracket 40. The battery 80 is limited and fixed by the bottom surface of the limiting member 43 and the top of the battery 80, ensuring a secure installation. The vehicle controller is integrated into the controller bracket 60.

[0036] With this configuration, the battery mounting structure is located on the top of the frame 70, rather than on one side of the frame 70, thereby optimizing the structural layout. Different types and structures of batteries 80 can be installed on the battery mounting bracket 40. The frame body 10 can not only install the batteries 80, but also integrate the vehicle controller, resulting in high space utilization, expansion of high-voltage battery capacity, and ensuring range.

[0037] Please refer to this as well. Figures 1 to 2A shock absorber 50 is provided between the frame body 10 and the left connecting bracket 20 and the right connecting bracket 30. The shock absorber 50 enables a flexible connection between the frame body 10 and the left connecting bracket 20 and the right connecting bracket 30. This flexible connection reduces the negative impact of vibration and impact on the battery 80 and the vehicle controller, and reduces the damage caused by mechanical impact to the precision components of the battery 80 and the vehicle controller. This effectively reduces equipment fatigue damage and extends their service life.

[0038] Please refer to this as well. Figures 1 to 2 In this embodiment, the shock absorber 50 includes a shock absorber pad 51 and a fixing post 52.

[0039] The shock-absorbing pad 51 is located between the frame body 10 and the left connecting bracket 20 and the right connecting bracket 30. The shock-absorbing pad 51 is a shock-absorbing soft pad, such as a highly elastic material like rubber. The shock-absorbing soft pad absorbs and disperses the mechanical vibration energy, reduces the vibration amplitude transmitted to the battery 80 and the vehicle controller, and avoids equipment structure loosening, internal component damage or electrical connection failure caused by long-term vibration.

[0040] The fixed column 52 is fixedly connected to the shock-absorbing pad 51. The upper end of the fixed column 52 passes through the frame body 10 and is threaded with a limit nut 53. The lower end of the fixed column 52 passes through the left connecting bracket 20 or the right connecting bracket 30 and is threaded with a limit nut 53. The frame body 10 is connected to the left connecting bracket 20 and the right connecting bracket 30 through the limit nuts 53 at the upper and lower ends of the fixed column 52. The connection is reliable.

[0041] Please refer to this as well. Figures 1 to 2 The frame body 10 includes two connectors 11 and a support frame 12 disposed between the two connectors 11. The two ends of the support frame 12 are fixedly connected to the two connectors 11 respectively. The left connecting bracket 20 and the right connecting bracket 30 are fixedly disposed on the two connectors 11 respectively.

[0042] Please refer to this as well. Figures 1 to 2 The top of the frame body 10 is provided with multiple support members 13. The cross-section of the support members 13 is an inverted U-shaped structure. The multiple support members 13 are distributed at intervals on the frame body 10. The battery mounting bracket 40 is fixedly installed on the top of the support members 13. The base plate 41 in the battery mounting bracket 40 can be connected to the support members 13 by bolts or the like to ensure connection strength and structural stability.

[0043] Please refer to this as well. Figures 1 to 2 In this embodiment, the bottom of the support member 13 is provided with a limiting groove 131, and the support member 13 is engaged with the support frame 12 through the limiting groove 131.

[0044] Please refer to this as well. Figures 1 to 2The left connecting bracket 20 and the right connecting bracket 30 are connected to the frame 70 by fasteners. Multiple fasteners are evenly distributed. This arrangement optimizes the stress distribution through uniform load distribution design, avoids local stress concentration, and significantly improves connection stability.

[0045] Preferably, in this embodiment, the fastener is a bolt. Bolts ensure a reliable connection between the left connecting bracket 20 and the right connecting bracket 30 and the frame 70, providing stable load-bearing capacity and facilitating quick disassembly and installation.

[0046] Optionally, the base plate 41 of the battery mounting bracket 40 is provided with a heat-conducting layer. This design can accelerate heat dissipation and ensure the stability and lifespan of the battery 80 in high-temperature environments. The heat-conducting layer can be graphene or an aluminum alloy heat sink, etc.

[0047] Optionally, the frame body 10 is equipped with standardized expansion slots to support plug-and-play use of external devices (such as range-extended charging modules and auxiliary power supplies). Through modular design, users can flexibly expand the energy configuration according to their needs to meet the range requirements in different scenarios.

[0048] The commercial vehicle new energy battery installation structure provided by this utility model has a frame body 10 fixedly installed on the top of the vehicle frame 70 via a left connecting bracket 20 and a right connecting bracket 30. The battery mounting bracket 40 and the controller bracket 60 are fixedly installed on the frame body 10, optimizing the structural layout. The battery 80 is installed on the base plate 41 of the battery mounting bracket 40. The battery 80 is fixed and secured by the bottom surface of the limiting member 43 abutting against the top of the battery 80, ensuring a secure installation. Figures 3 to 5 As shown, it can not only be adapted to different types and structures of batteries 80, but also has high space utilization, can expand the capacity of high-voltage batteries, and ensure range.
