Description

Technical Field

[0001] This utility model relates to the field of battery accessory technology, and more specifically, to a mounting bracket for an automotive power battery box. Background Technology

[0002] Compared to conventional fuel-powered buses, new energy buses offer advantages such as being green, energy-saving, and environmentally friendly. The power battery box, as a core component of new energy buses, plays a decisive role in their development. Currently, the rear compartments of large and medium-sized new energy buses are rectangular, with only one opening for installing the power battery box. However, due to the limited space in the rear compartment, the narrow passageway and small operating space for installing the power battery box make it difficult for workers to tighten the bolts on the inner side of the battery box and secure the high- and low-voltage wiring harnesses, severely impacting the production and assembly efficiency of new energy buses. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an automotive power battery box mounting bracket, including an inner bracket and an outer bracket sleeved on the outside of the inner bracket. One end of the outer bracket in the long axis direction is provided with an opening. The inner bracket slides inside the outer bracket along the long axis direction. Inner limiting members are provided on both sides of the outer bracket and the inner bracket in the long axis direction to limit the sliding of the inner bracket. Outer limiting members that intersect with the inner limiting members are provided on the outside of the inner limiting members. The two ends of the outer limiting members are respectively connected to the inner bracket and the outer bracket. The intersection of the outer limiting members and the inner limiting members fixes the inner bracket inside the outer bracket.

[0004] In a preferred embodiment, recessed grooves are provided at the bottom of both sides of the inner cavity of the outer bracket, and a plurality of pulleys are embedded in the grooves. The bottom of the inner bracket is attached to the pulleys and slides inside the outer bracket.

[0005] In a preferred embodiment, the inner limiting member includes a limiting strip fixed to the outer side wall of the inner bracket and a limiting groove recessed outward on the outer side wall of the outer bracket. The limiting strip is inserted into the inside of the limiting groove, and the limiting strip and the limiting groove extend along the long axis of the outer bracket.

[0006] In a preferred embodiment, a baffle is provided at the end of the outer bracket away from the opening. Both ends of the baffle extend a certain distance to both sides of the outer bracket and are embedded with bearings. The outer limiting member includes a rotating shaft located on the outside of the outer bracket. The end of the rotating shaft away from the opening is inserted into the inside of the bearing. A collar is sleeved on the outside of the end of the rotating shaft near the opening. A connecting plate fixed at the edge of the outer bracket is connected to the edge of the collar.

[0007] In a preferred embodiment, a connecting rod perpendicular to the axis of the rotating shaft is installed on the outer wall of the rotating shaft, and an arc-shaped rod with the axis of the rotating shaft as the center and surrounding the rotating shaft is installed at the other end of the connecting rod. The number of arc-shaped rods and connecting rods are both several.

[0008] A connecting rod perpendicular to the axis of the shaft is installed on the outer wall of the shaft. An arc-shaped rod with the axis of the shaft as the center and surrounding the shaft is installed at the other end of the connecting rod. There are several arc-shaped rods and connecting rods.

[0009] In a preferred embodiment, a limiting plate extending along the long axis of the outer support is provided at the bottom of the limiting groove. After the arc-shaped rod is inserted into the arc-shaped through hole, the end of the arc-shaped rod fits against the limiting plate to limit the rotation of the rotating shaft.

[0010] In a preferred embodiment, the outer bracket is provided with external connecting ears on both sides of the opening, and the inner bracket is provided with internal connecting ears that match the external connecting ears on both sides of the opening. The end of the connecting rod facing the opening is fixed with a limiting piece that is inserted between the external connecting ear and the internal connecting ear.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-5 The illustrated automotive power battery box mounting bracket includes an inner bracket 1 and an outer bracket 2 sleeved outside the inner bracket 1. One end of the outer bracket 2 along its long axis is provided with an opening 3. The inner bracket 1 slides inside the outer bracket 2 along its long axis. Inner limiting members 4 are provided on both sides of the outer bracket 2 and the inner bracket 1 along their long axes to limit the sliding of the inner bracket 1. Outer limiting members 5, which intersect with the inner limiting members 4, are provided on the outer side of the inner limiting members 4. The two ends of the outer limiting members 5 are connected to the inner bracket 1 and the outer bracket 2 respectively. The outer limiting members 5 and the inner limiting members 4 intersect to fix the inner bracket 1 inside the outer bracket 2. A handle 15 is also installed on the end of the inner bracket 1 near the opening 3.

[0021] Based on the above, the outer bracket 2 is fixed to the rear cabin of the bus, and the inner bracket 1 carries the power battery box. During installation, the inner bracket 1 is pulled by the handle 15 so that it slides along the long axis of the outer bracket 2 (the opening 3 is the sliding entrance and exit). The inner limit piece 4 restricts the lateral displacement during sliding. The outer limit piece 5 and the inner limit piece 4 cooperate to fix the inner bracket 1 inside the outer bracket 2, thereby realizing the position adjustment and fixation of the battery box.

[0022] Furthermore, by using the sliding cooperation of inner and outer brackets, the operational challenges of the narrow space in the rear cabin of the bus are solved, allowing the battery box position to be adjusted without having to go deep inside, thus simplifying the installation process.

[0023] The bottom of both sides of the inner cavity of the outer bracket 2 is provided with recessed grooves 6, and a number of pulleys 7 are embedded in the grooves 6. The bottom of the inner bracket 1 is attached to the pulleys 7 and slides inside the outer bracket 2.

[0024] Based on the above, when the inner support 1 slides, its bottom contacts the pulley 7, and the pulley 7 rolls in the groove 6, which converts the sliding friction between the inner support 1 and the outer support 2 into rolling friction, reduces frictional resistance, and makes the inner support 1 slide more smoothly along the long axis of the outer support 2.

[0025] The pulley 7 reduces sliding resistance, making it easier to pull the inner support 1, adapting to the operating force of workers in narrow spaces, and improving adjustment efficiency.

[0026] The inner limiting member 4 includes a limiting strip 41 fixed on the outer side wall of the inner bracket 1 and a limiting groove 42 recessed outward on the outer side wall of the outer bracket 2. The limiting strip 41 is inserted into the inside of the limiting groove 42, and the limiting strip 41 and the limiting groove 42 extend along the long axis of the outer bracket 2.

[0027] Based on the above, when the inner support 1 slides, the limiting strip 41 slides synchronously along the limiting groove 42 with the inner support 1. The insertion and cooperation between the limiting strip 41 and the limiting groove 42 restricts the lateral displacement of the inner support 1 (perpendicular to the long axis direction), preventing the inner support 1 from tilting or deviating when sliding, and ensuring that the sliding direction is always along the long axis of the outer support 2.

[0028] The long axis extension design of the limiting strip 41 and the limiting groove 42 forms a basic guiding constraint, ensuring the stability of the battery box's posture during the sliding process and avoiding installation deviations caused by offset.

[0029] The outer support 2 is provided with a baffle 8 at the end away from the opening 3. The two ends of the baffle 8 extend a certain distance to both sides of the outer support 2 and are embedded with bearings 9. The outer limiting member 5 includes a rotating shaft 51 located on the outside of the outer support 2. The end of the rotating shaft 51 away from the opening 3 is inserted into the inside of the bearing 9. A collar 52 is sleeved on the outside of the end of the rotating shaft 51 near the opening 3. A connecting plate 53 fixed at the edge of the collar 52 is connected to the edge of the outer support 2.

[0030] Based on the above, the baffle 8 limits the extreme position of the sliding of the inner support 1, the bearing 9 provides a rotation fulcrum for the rotating shaft 51, and the collar 52 and the connecting plate 53 fix the axial position of the rotating shaft 51 (to prevent axial movement), so that the rotating shaft 51 can only rotate stably around its own axis, in preparation for the subsequent driving of the arc rod locking.

[0031] The rotating shaft 51 achieves stable rotation through the bearing 9 and the collar 52. The structure is compact and durable, ensuring the reliable mechanical action of the outer limit member 5.

[0032] A connecting rod 54 perpendicular to the axis of the rotating shaft 51 is installed on the outer wall of the rotating shaft 51. An arc-shaped rod 55 with the axis of the rotating shaft 51 as the center and surrounding the rotating shaft 51 is installed at the other end of the connecting rod 54. There are several arc-shaped rods 55 and connecting rods 54. An arc-shaped through hole 56 with the axis of the rotating shaft 51 as the center and surrounding the rotating shaft 51 is opened on the limiting strip 41 and the limiting groove 42. After the rotating shaft 51 rotates and drives the connecting rod 54 and the arc-shaped rod 55 to move, the arc-shaped rod 55 is inserted into the inside of the arc-shaped through hole 56.

[0033] Based on the above, when the rotating shaft 51 is rotated, the connecting rod 54 drives the arc-shaped rod 55 to make a circular motion around the axis of the rotating shaft 51, so that the arc-shaped rod 55 is inserted into the arc-shaped through hole 56 of the limiting strip 41 and the limiting groove 42. By using the cooperation between the arc-shaped rod 55 and the arc-shaped through hole 56, the relative sliding between the inner support 1 and the outer support 2 is restricted (the arc-shaped structure can withstand the force along the long axis direction).

[0034] The insertion of the arc-shaped rod 55 into the arc-shaped through hole 56 forms a mechanical lock, while the distribution of multiple sets of connecting rods 54 and arc-shaped rods 55 evenly distributes the force, improving the stability of the fixation.

[0035] The bottom of the limiting groove 42 is provided with a limiting plate 10 extending along the long axis of the outer bracket 2. After the arc rod 55 is inserted into the arc through hole 56, the end of the arc rod 55 is attached to the limiting plate 10 to limit the rotation of the rotating shaft 51.

[0036] Based on the above, after the arc-shaped rod 55 is inserted into the arc-shaped through hole 56, its end is in contact with the limiting plate 10. The limiting plate 10 blocks the arc-shaped rod 55 from continuing to rotate, preventing the rotating shaft 51 from rotating in the opposite direction and causing the arc-shaped rod 55 to come out, thus ensuring a stable locking state.

[0037] The limiting plate 10 forms a reverse constraint to avoid locking failure caused by factors such as vibration, thereby enhancing structural reliability.

[0038] The outer bracket 2 has external connecting ears 11 on both sides of the opening 3. The inner bracket 1 has internal connecting ears 12 on both sides of the opening 3 that match the external connecting ears 11. The end of the connecting rod 54 facing the opening 3 is fixed with a limiting piece 13 that is inserted between the external connecting ear 11 and the internal connecting ear 12. The limiting piece 13, the internal connecting ear 12 and the external connecting ear 11 are all provided with screw holes. Bolts 14 that limit the limiting piece 13, the internal connecting ear 12 and the external connecting ear 11 are inserted into the screw holes.

[0039] Based on the above, when the rotating shaft 51 rotates, the limiting piece 13 moves with the connecting rod 54 to between the outer connecting ear 11 and the inner connecting ear 12. The three screw holes are aligned. After the bolt 14 is tightened through the screw hole, the inner bracket 1 and the outer bracket 2 are rigidly fixed to the limiting piece 13 through the connecting ear, forming a secondary locking to prevent relative sliding.

[0040] Bolt 14 and connecting lug cooperate to achieve double fixation, and combined with the mechanical locking of arc rod 55, the overall structure is further stabilized and adapted to the vibration environment during vehicle operation.
