Description

Technical Field

[0001] The present invention relates to the technical field of motor brackets, and in particular to a motor bracket for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use non-traditional fuels or new on-board power devices, which mainly include pure electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV) and fuel cell electric vehicles (FCEV). New energy vehicles mainly rely on power batteries to store electrical energy and obtain energy from the power grid through charging ports. The electronic control system then receives driver instructions and adjusts the current output. Finally, the motor converts electrical energy into mechanical energy to drive the wheels to rotate. The general motor with legs is installed at the bottom of the vehicle through the motor bracket to provide better power transmission efficiency.

[0003] The automobile motor bracket is installed on the bottom of the car with bolts, and then the motor support foot is fixed to the motor bracket with bolts to achieve the purpose of stable installation. Due to the large weight of the motor body, it must rely on additional structural parts for lifting and positioning during installation. These auxiliary tools need to be adjusted in advance for height and angle to ensure that the motor support foot is aligned with the bracket bolt hole. The process often requires multiple people to cooperate in repeated calibration. However, the motor itself has a certain quality. When the motor needs to be repaired or replaced, it is also necessary to support the motor and then remove the bolts one by one. The steps are cumbersome and prone to errors, and special tools are required for assistance. If the tools are used improperly, it may cause bolt thread slippage or structural deformation. In addition, due to the narrow space at the bottom of the vehicle, maintenance personnel need to operate in a limited space, which further increases the difficulty of operation. If the supporting equipment fails, the motor may fall suddenly, causing the risk of injury to the maintenance personnel. If they keep bending over and looking up at the bottom of the car for a long time, it is easy to cause fatigue, further increasing the probability of misoperation. Summary of the invention

[0021] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0022] Please refer to Figures 1 to 8 , a motor bracket for a new energy vehicle, comprising: a support 1, the support 1 is integrally in a rectangular plate structure, made of high-strength aluminum alloy material, precision die-cast, with good strength and lightweight characteristics. A plurality of mounting holes 2 are symmetrically opened on the support 1, and bolts 3 are threadedly connected in the mounting holes 2. The mounting holes 2 symmetrically opened on the support 1 can be threadedly connected with corresponding-sized bolts 3 to stably mount the motor bracket on the vehicle body of the new energy vehicle. One side of the support 1 is provided with a motor body 4, which is a key component of the drive system of the new energy vehicle. A motor support leg 5 is fixedly arranged on the motor body 4. The motor support leg 5 is L-shaped and is closely combined with the motor body 4 to ensure that the motor can be mounted on the support 1.

[0023] Specifically, please refer to Figures 1 to 7 , a motor bracket for a new energy vehicle further comprises: a positioning mechanism 6. The positioning mechanism 6 is arranged on the support 1. The positioning mechanism 6 includes a fixed strip 7 fixedly arranged on the support 1. First limiting strip 8 and second limiting strip 9 are fixedly and symmetrically mounted on the fixed strip 7. The motor support leg 5 is located between the first limiting strip 8, the second limiting strip 9 and the support 1. The positioning mechanism 6 is used to quickly position and install the motor body 4 through the motor support leg 5.

[0024] By inserting the motor support feet 5 on the motor body 4 into the gaps between the first limiting strip 8, the second limiting strip 9 and the support 1, the first limiting strip 8 and the second limiting strip 9 position and install the motor support feet 5 while performing preliminary limiting. At this time, both sides of the motor support feet 5 are in close contact with the first limiting strip 8 and the second limiting strip 9 respectively, and the bottom is in contact with the support 1, realizing the precise positioning of the motor body 4 in the horizontal and vertical directions. It avoids the need to spend a lot of time on position adjustment and calibration in traditional motor installation. With the positioning space formed by the first limiting strip 8, the second limiting strip 9 and the fixing strip 7, the motor support feet 5 can be quickly and accurately positioned, ensuring the accuracy of motor installation, greatly shortening the installation time, and eliminating the need to use external structural parts to lift or clamp the motor body 4. In large-scale production scenarios, it can significantly improve production efficiency and speed up the overall production rhythm.

[0025] For details, please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 8 . A motor bracket for a new energy vehicle further includes: a load-bearing mechanism 27, the load-bearing mechanism 27 is arranged on the support 1, the load-bearing mechanism 27 includes connecting plates 32 symmetrically arranged on both sides of the motor body 4, and arc-shaped rods 33 are fixedly arranged at both ends of the connecting plates 32. The load-bearing mechanism 27 is used to disperse the weight of the motor body 4 on the positioning mechanism 6.

[0026] By the load-bearing mechanism 27 effectively dispersing the weight of the motor body 4 borne by the positioning mechanism 6, the burden on the positioning mechanism 6 is reduced, and the reliability and durability of the entire motor bracket are improved. The arc-shaped rods 33 in the load-bearing mechanism 27 are arranged in a manner that fits the motor body 4. They not only have good mechanical properties, can effectively disperse and transfer forces, and transfer the received weight to the support 1 in a more dispersed manner, increasing the stress-bearing area on the support 1 and making the stress distribution more uniform, but also can play a role in buffering and shock absorption to a certain extent.

[0027] Among them, the first limiting strip 8 and the second limiting strip 9 are arranged in an L shape. A flexible gasket 36 is fixedly arranged on the side of the arc-shaped rod 33 close to the motor body 4, and the flexible gasket 36 is in contact with the motor body 4. After the motor support feet 5 are inserted into the first limiting strip 8, the second limiting strip 9 and are in contact with the fixing strip 7, their bottom surfaces are in contact with the support 1, the sides are constrained by the vertical limiting section, and the top is covered by the horizontal limiting section, forming a three-dimensional limiting constraint, thus meeting the installation requirements of quick installation and precise positioning. The flexible gasket 36 inside the arc-shaped rod 33 forms a double buffering effect, which can dissipate vibration energy and avoid damage to the load-bearing mechanism 27 caused by resonance effects.

[0028] For details, please refer to Figures 1 to 3 and Figures 5 to 7, Further, the positioning mechanism 6 further includes insertion holes 10 provided at one end of the first limiting strip 8 and the second limiting strip 9 away from the fixed strip 7. A notch 11 is also provided on the second limiting strip 9. A resisting rod 12 is movably inserted into the insertion hole 10, and a clamping hole 13 is provided through the resisting rod 12. The insertion hole 10 is provided to be able to movably insert the resisting rod 12, and the resisting rod 12 can move flexibly within the insertion hole 10.

[0029] By inserting the motor feet 5 at the bottom of the motor body 4 between the first limiting strip 8 and the second limiting strip 9, the motor can be quickly positioned. The two sides of the motor feet 5 are respectively in close contact with the first limiting strip 8 and the second limiting strip 9. One side at the bottom of the motor feet contacts the support 1, achieving precise positioning of the motor body 4 in the horizontal and vertical directions, avoiding the need to spend a lot of time on position adjustment and calibration in traditional motor installation, without the need to use additional tools to lift or clamp the motor body 4, reducing equipment dependence, and simplifying the installation and disassembly processes. Through the three-dimensional geometric constraints of the first limiting strip 8 and the second limiting strip 9, it is convenient for operators to quickly complete installation or disassembly in a narrow space.

[0030] Among them, a fixed block 14 is fixedly provided on one side of the second limiting strip 9. An installation cavity 15 is opened on the fixed block 14. A first spring 16 is fixedly installed in the installation cavity 15. A first resisting block 17 is fixedly provided on one side of the first spring 16. The outer surface of the first resisting block 17 slides on the inner wall of the installation cavity 15, and the end of the first resisting block 17 fits against the end of the resisting rod 12. A groove 18 is opened on the fixed block 14. A rotating shaft 19 is fixedly connected in the groove 18. A rotating block 20 is rotatably connected to the outer surface of the rotating shaft 19. One end of the rotating block 20 is stuck in the clamping hole 13. A moving cavity 21 is also opened on the side wall of the groove 18. A second spring 22 is provided on one side of the moving cavity 21. A second resisting block 23 is slidably provided on the inner wall of the moving cavity 21. The second spring 22 is sleeved on the outer surface of the second resisting block 23, and the end of the second resisting block 23 fits against the end of the rotating block 20. Opposite surfaces of the groove 18 are provided with sliding grooves 24. A moving piece 25 is slidably connected in the sliding grooves 24. A fixed rod 26 is fixedly provided on one side of the moving piece 25. The fixed rod 26 abuts against the surface of the rotating block 20 away from the second resisting block 23.

[0031] After the push rod 12 is inserted into the plug hole 10, the rotating block 20 is clamped into the clamping hole 13 of the push rod 12, and the motor support foot 5 is limited in multiple dimensions, avoiding the vertical jump caused by the loosening of the bolt 3 in the traditional installation. The limit strip 1 8 and the limit strip 2 9 fit the two sides of the motor support foot 5 to limit the displacement in the X-axis and Z-axis directions. After the push rod 12 is locked by the rotating block 20, its end is against the front end or rear end of the motor support foot 5 to limit the displacement in the Y-axis direction, forming a three-dimensional rigid limit to prevent the motor from sliding forward, backward, left, right, and up and down. The spring 16 and the push block 17 provide elastic pressure to ensure that the push rod 12 is continuously pressed. The clamping setting of the rotating block 20 and the clamping hole 13 prevents the push rod 12 from falling out through mechanical interlocking, ensuring the continuous stability of the limiting force.

[0032] Please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 8 Furthermore, the load-bearing mechanism 27 further includes a through hole 28 penetrating the support 1, and a bidirectional lead screw 29 is penetrating the through hole 28. A movable block 30 is symmetrically and threadedly connected to the bidirectional lead screw 29, and a connecting rod 31 is fixedly arranged on the movable block 30, and the end of the connecting rod 31 is fixedly connected to the connecting plate 32. A limit block 34 is fixedly arranged at one end of the bidirectional lead screw 29, and a rotating block 35 is fixedly arranged at the other end of the bidirectional lead screw 29.

[0033] When the rotary block 35 rotates, the movable blocks 30 on both sides move synchronously toward the center, and the arc rod 33 drives the flexible gasket 36 to fit the motor body 4 and limit it. The arc rod 33 can effectively disperse and transmit force, and transmit the received weight to the support 1 in a more dispersed manner, so that the force-bearing area on the support 1 is increased, the stress distribution is more uniform, and the weight of the motor body 4 borne by the positioning mechanism 6 is effectively dispersed, thereby reducing the burden on the positioning mechanism 6.

[0034] Through all the above embodiments, the working principle of the present invention is: The support 1 is firmly installed on the vehicle body of the new energy vehicle by means of threaded connection with bolts 3 of corresponding sizes through the mounting holes 2. Then, the motor body 4 is turned over so that the motor feet 5 at the bottom of the motor body 4 are aligned with and inserted into the gaps between the first limiting strip 8 and the second limiting strip 9 and the support 1. The first limiting strip 8 and the second limiting strip 9 position and install the motor bracket while performing preliminary limiting. At this time, both sides of the motor feet 5 are in close contact with the first limiting strip 8 and the second limiting strip 9 respectively, and the bottom is in contact with the support 1, realizing the precise positioning of the motor body 4 in the horizontal and vertical directions. It avoids the need to spend a lot of time on position adjustment and calibration in traditional motor installation. With the positioning space formed by the first limiting strip 8, the second limiting strip 9 and the fixing strip 7, the motor feet 5 can be quickly and accurately positioned, ensuring the accuracy of motor installation. The installation time is greatly shortened, and there is no need to use external structural parts to lift or clamp the motor body 4; Subsequently, the abutting rod 12 is inserted into the insertion holes 10 of the first limiting strip and the second limiting strip 9. At this time, the clamping hole 13 of the abutting rod 12 will gradually approach the rotating block 20. The operator needs to squeeze the movable piece 25 towards the second spring 22 to prompt the rotating block 20 to rotate until the clamping hole 13 on the abutting rod 12 is aligned with the sharp end of the rotating block 20. Then release the movable piece 25, and the second spring 22 prompts the rotating block 20 to reset. At this time, the first abutting rod 12 and the second abutting rod 12, under the action of the first spring 16 and the second spring 22, snap the rotating block 20 into the clamping hole 13 and press against the abutting rod 12 to ensure that the abutting rod 12 continues to press tightly. The engagement setting of the rotating block 20 and the clamping hole 13 prevents the abutting rod 12 from coming out through mechanical interlocking, ensuring the continuous stability of the limiting force. The first limiting strip 8 and the second limiting strip 9 position and install the motor feet 5 while performing preliminary limiting, and then the abutting rod 12 further limits the motor feet 5 again. The three-dimensional geometric constraints facilitate the operator to quickly complete the installation in a narrow space. When the motor body 4 needs to be disassembled, only need to press the movable piece 25 and move it along the chute 24 towards the second spring 22 again to prompt the rotating block 20 to rotate. The first spring 16 ejects the abutting rod 12 through the first abutting block 17. At this time, the operator can pull out the abutting rod 12 from the insertion hole 10 and then remove the motor to complete the rapid disassembly of the motor. There is no need to use additional tools to lift or clamp the motor body 4, reducing equipment dependence and simplifying the installation and disassembly processes; After the motor body 4 is positioned and installed by the positioning mechanism 6, by rotating the rotating block 35 on the bidirectional lead screw 29, the two side movable blocks 30 move synchronously towards the center or away, prompting the arc-shaped rod 33 to drive the flexible gasket 36 to fit against the motor body 4 and limit it. The arc-shaped rod 33 can effectively disperse and transmit forces, and transmit the received weight to the support 1 in a more dispersed manner, increasing the stress-bearing area on the support 1 and making the stress distribution more uniform, effectively dispersing the weight of the motor body 4 borne by the positioning mechanism 6 and reducing the burden on the positioning mechanism 6.

[0035] Those of ordinary skill in the art should understand that the discussion of any of the above embodiments is merely exemplary. Under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail.
