Description

Technical Field

[0001] The utility model relates to the technical field of motor installation for heavy trucks, and more specifically, to a motor mounting structure for heavy trucks. Background Art

[0002] In the field of heavy trucks, with the continuous development of technology, electric motor drive has gradually become an important power option. As a key component connecting the motor and the heavy truck body, at present, the motor mounting bracket structure adopted by domestic pure electric heavy trucks is mainly composed of parts welded together by manual welding. This structure has certain errors due to manual welding, which in turn leads to a decrease in part accuracy, and the bracket is relatively heavy and costly, which is not conducive to lightweight design. To solve the above technical problems, technicians in this field have proposed using sheet metal stamping parts welded or bolted and fixed. This structural form has disadvantages such as complex structure, large number of parts, low structural strength, poor reliability, and poor vibration damping effect.

[0003] Regarding the above problems, for the technical problems of the structural form of domestic pure electric heavy trucks having disadvantages such as complex structure, large number of parts, low structural strength, poor reliability, and poor vibration damping effect, after a large number of searches, a motor mounting bracket structure for heavy trucks with the patent publication number CN220483071U was found, which includes: a casting bracket, a soft pad assembly, and an active side bracket; the soft pad assembly includes: an upper soft pad, a sleeve, and a lower soft pad; the casting bracket includes: a vehicle frame mounting base plate and a bracket loading plate. A soft pad mounting hole is provided on the bracket loading plate, a boss structure is formed at the outer edge corner of the vehicle frame mounting base plate, and a bracket mounting through hole is provided on the boss structure. An installation hole reinforcing rib is provided on the side of the bracket mounting through hole, and a boss reinforcing rib is provided between the boss structures. The casting structure has good consistency and realizes four-point arrangement, further improving the versatility; the structural form and the distribution of the reinforcing ribs are designed to make the overall structural arrangement more reasonable, reduce the parts prone to stress concentration, thereby improving the reliability. At the same time, lightweight improvement is carried out, which not only meets the function of supporting the motor but also can play a role in vibration damping and buffering; however, the technical solution provided by this patent has the following problems:

[0004] (1) According to the description of the patent publication number CN220483071U, during the suspension process of the motor, the motor is fastened to the casting bracket by bolts to ensure the structural stability and normal operation of the motor. However, bolt fixing requires tightening operations of multiple bolts, which increases the installation time and complexity and reduces the work efficiency.

[0005] (2) And the motor will continuously generate vibrations during operation. This continuous vibration causes the materials inside the cushion assembly to continuously bear repeated stress. Under the influence of long-term stress changes, the cushion material will accelerate into a fatigue aging state, and its elastic performance will gradually decline. Due to the reduction of the elastic performance of the cushion assembly, the ability to buffer and absorb the motor vibration weakens, resulting in the more intense transmission of the motor vibration to parts such as the frame of the heavy truck, thereby reducing the driving stability of the heavy truck.

[0006] The utility model does not need to be tightened and fixed by multiple bolts, thus reducing the installation time and operation complexity required, improving work efficiency; and can reduce the influence of motor vibration on the cushion assembly, extend the service life of the cushion assembly, and ultimately improve the driving stability of the heavy truck. Summary of the Invention

[0007] The purpose of the utility model is to solve the technical problems proposed in the above background technology and provide a motor mounting structure for a heavy truck.

[0008] To achieve the above object, the utility model provides the following technical solution: A motor mounting structure for a heavy truck, comprising: a U-shaped plate, a placement plate is arranged inside the U-shaped plate, a motor is placed on the upper surface of the placement plate, clamping assemblies are arranged at the left and right ends of the motor, and damping assemblies are arranged at the left and right ends of the motor; The clamping assembly includes guide grooves opened on the left and right end surfaces of the U-shaped plate, guide rods sliding inside the guide grooves, electric push rods embedded and connected to the left and right ends of the U-shaped plate, and clamping plates clamping the outer surface of the motor; The damping assembly includes a damping seat fixed to the telescopic end of the electric push rod, a connecting rod telescopically connected inside the damping seat, a first damper arranged between the connecting rod and the damping seat, and a limiting block fixedly connected to the outer surface of the connecting rod.

[0009] Further preferred solution: Clamping plates are clamped on the left and right end surfaces of the motor. The clamping plates are arc-shaped and symmetrically arranged at both ends of the motor. A rubber pad is arranged between the clamping plates and the motor.

[0010] Further preferred solution: Guide rods are fixedly connected to the outer side surfaces of the clamping plates. The guide rods are respectively distributed at both ends of the clamping plates. Guide grooves are respectively opened on the left and right end surfaces of the U-shaped plate. The guide rods are respectively slidably connected inside the guide grooves.

[0011] Further preferred solution: Electric push rods are arranged in the middle of the guide rods. One ends of the electric push rods are respectively embedded and connected inside the two ends of the U-shaped plate.

[0012] Further preferred solution: A shock-absorbing seat is fixedly connected to the telescopic end of the electric push rod. An adjusting rod is telescopically connected to the inside of the shock-absorbing seat. The other end of the adjusting rod is fixedly connected to the outer surface of the clamping plate. A second damper is provided at the lower end of the placement plate, and a plurality of the second dampers are provided.

[0013] Further preferred solution: A first damper is arranged inside the shock-absorbing seat. One end of the first damper is fixedly connected to the inner wall of the shock-absorbing seat, and the other end of the first damper is fixedly connected to the adjusting rod. A limiting block is fixedly connected to the outer surface of the adjusting rod, and the limiting block is slidably connected to the inner wall of the shock-absorbing seat.

[0014] Further preferred solution: Vertical rods are respectively fixedly connected to the upper end surface of the U-shaped plate, and a plurality of the vertical rods are provided. An installation plate is fixedly connected to the upper ends of the vertical rods. A plurality of threaded holes are formed in the surface of the installation plate, and a protective pad is arranged on the upper end surface of the installation plate.

[0015] Beneficial effects:

[0016] 1. By providing a clamping assembly, first place the motor on the placement plate, and then start the electric push rods located at both ends of the motor respectively. When the telescopic ends of the electric push rods move, they will drive the shock-absorbing seat to move, and the shock-absorbing seat will further drive the adjusting rod to move, so that the adjusting rod pushes the clamping plate towards the motor. During this process, the guiding rod will slide in the guiding groove to play a guiding role until the clamping plates at both ends respectively contact the motor and clamp and fix it. In this way, it is not necessary to tighten and fix with multiple bolts, thereby reducing the installation time and operation complexity and improving work efficiency.

[0017] 2. By providing a shock-absorbing assembly, since the adjusting rod is pushed to compress the first damper after the clamping plate clamps and fixes the motor, at this time, the first damper will exert a reaction force on the adjusting rod. When the motor generates vibrations in the left and right directions, the vibration force is first transmitted to the clamping plate and then from the clamping plate to the adjusting rod. If the motor vibrates to the left, the left adjusting rod will further compress the first damper, while the first damper in the compressed state on the right will have a tendency to stretch, thereby generating a rightward thrust on the right adjusting rod. This thrust acts on the motor through the adjusting rod and the clamping plate to play a certain buffering role and prevent the motor from continuing to move to the left; similarly, if the motor vibrates to the right, the right adjusting rod will further compress the first damper, and the first damper on the left will stretch and generate a leftward thrust on the left adjusting rod to prevent the motor from continuing to move to the right. At the same time, the second dampers under the placement plate can reduce the transmission of the motor's vertical vibrations, which can reduce the impact of the motor's vibrations on the cushion assembly, extend the service life of the cushion assembly, and ultimately improve the driving stability of the heavy truck.

[0018] 3. In summary, the clamping assembly of the motor mount structure for heavy trucks does not need to be tightened and fixed by multiple bolts, thus reducing the installation time and operational complexity, improving work efficiency; the shock absorption assembly can reduce the impact of motor vibration on the cushion assembly, extend the service life of the cushion assembly, and ultimately improve the driving stability of heavy trucks.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-5 drawings in the embodiments of the present utility model.

[0026] Please refer to Figures 1-5, in the embodiment of the present utility model, a motor mounting structure for a heavy truck includes: a U-shaped plate 1, which is a frame structure providing installation and support for a placement plate 5, a motor 4 and other components to ensure the stability of the entire device. The placement plate 5 is arranged inside the U-shaped plate 1. The placement plate 5 is used to carry the motor 4 and provide an installation position for the motor 4, so that it can be stably supported inside the U-shaped plate 1. The motor 4 is placed on the upper surface of the placement plate 5. Clamping components are arranged at the left and right ends of the motor 4, and damping components are arranged at the left and right ends of the motor 4; the clamping components include guide grooves 9 opened on the left and right end surfaces of the U-shaped plate 1, and guide rods 10 sliding inside the guide grooves 9. During the process of clamping the motor 4, the guide rods 10 slide in the guide grooves 9 to play a guiding role, ensuring that the clamping plates 6 can accurately move towards the motor 4 direction, and guaranteeing the accuracy and stability of clamping. Electric push rods 11 embedded and connected at the left and right ends of the U-shaped plate 1. The electric push rods 11 serve as power sources, and the movement of their telescopic ends drives the shock-absorbing seats 12, connecting rods 7 and clamping plates 6 to move, realizing the clamping and loosening operations of the motor 4. Clamping plates 6 clamped on the outer surface of the motor 4; the clamping plates 6 are in direct contact with the motor 4 and move towards the motor 4 direction to clamp and fix the motor 4, preventing the motor 4 from shifting during operation. The damping components include shock-absorbing seats 12 fixed at the telescopic ends of the electric push rods 11. The shock-absorbing seats 12 provide installation positions for the connecting rods 7 and dampers 13. At the same time, when the motor 4 generates vibrations during operation, it can absorb part of the vibration energy and reduce the impact of vibrations on the electric push rods 11. Connecting rods 7 telescopically connected inside the shock-absorbing seats 12. The connecting rods 7 can telescopically move inside the shock-absorbing seats 12 when the motor 4 vibrates, transmit the vibration force to the dampers 13, and at the same time, through connection with the clamping plates 6, transmit the reaction force of the dampers 13 to the clamping plates 6, thereby playing a buffering role for the motor 4. Dampers 13 arranged between the connecting rods 7 and the shock-absorbing seats 12. When the motor 4 generates vibrations in the left and right directions, the dampers 13 will compress or extend according to the vibration direction of the motor 4, exert a reaction force on the connecting rods 7, and act on the motor 4 through the connecting rods 7 and the clamping plates 6 to play a buffering role and prevent the motor 4 from continuing to move in the vibration direction. Limit blocks 15 fixedly connected to the outer surface of the connecting rods 7. When the motor 4 vibrates, the limit blocks 15 move as the connecting rods 7 telescopically move inside the shock-absorbing seats 12. Their function is to prevent the connecting rods 7 from slipping out of the shock-absorbing seats 12 and ensure the normal operation of the damping components.

[0027] In the embodiment of the present utility model, the clamping plates 6 are clamped on the left and right end surfaces of the motor 4. The main function of the clamping plates 6 is to fix the motor 4, prevent the motor 4 from shifting or shaking during operation, and ensure the stability of the motor 4. The clamping plates 6 are arc-shaped. The arc-shaped clamping plates 6 can better fit the outer surface of the motor 4, increase the contact area with the motor 4, and improve the stability and firmness of clamping. They are symmetrically arranged at both ends of the motor 4. The symmetrical arrangement can make the motor 4 receive uniform clamping force in the left and right directions, further enhance the stability of the motor 4, and prevent the motor 4 from tilting or shifting due to uneven force. A rubber pad 8 is arranged between the clamping plates 6 and the motor 4. The rubber pad 8 has elasticity and anti-slip performance, which can play a buffering role when the clamping plates 6 clamp the motor 4, reduce the rigid contact between the motor 4 and the clamping plates 6, and reduce the risk of damage to the motor 4 housing caused by vibration and clamping force. At the same time, the rubber pad 8 can also increase the friction force to make the clamping more firm.

[0028] In the embodiment of the present utility model, the guide rods 10 are fixedly connected to the outer surface of the clamping plates 6. The guide rods 10 provide guidance and support for the movement of the clamping plates 6, ensuring that the clamping plates 6 can move along the correct direction during the process of clamping the motor 4, and improving the accuracy and stability of clamping. The guide rods 10 are respectively distributed at both ends of the clamping plates 6. The guide rods 10 distributed at both ends can make the clamping plates 6 move more smoothly during the movement, prevent the clamping plates 6 from tilting or twisting, and ensure that the clamping force is evenly distributed on the motor 4. Guide grooves 9 are respectively opened on the left and right end surfaces of the U-shaped plate 1. The guide rods 10 are respectively slidably connected inside the guide grooves 9. The guide grooves 9 provide a moving track for the guide rods 10, limit the moving direction of the guide rods 10, so as to ensure that the clamping plates 6 can accurately move towards the motor 4 for clamping or move away from the motor 4 to loosen, and at the same time prevent the clamping plates 6 from having unnecessary displacement in other directions, ensuring the reliability and stability of the entire clamping process.

[0029] In the embodiment of the present utility model, the electric push rod 11 is arranged in the middle of the guide rods 10. Such a layout can make the thrust of the electric push rod 11 act on the clamping plates 6 more evenly. Since the guide rods 10 are distributed at both ends of the clamping plates 6, the electric push rod 11 located in the middle position can push the clamping plates 6 to move balancedly, avoiding tilting or shifting of the clamping plates 6 during the movement, and ensuring the stability of the clamping process. One end of the electric push rod 11 is respectively embedded and connected inside the two ends of the U-shaped plate 1. Embedding and connecting the electric push rod 11 inside the two ends of the U-shaped plate 1 can make the electric push rod 11 obtain stable support and fixation. The U-shaped plate 1 provides an installation base for the electric push rod 11, ensuring that the electric push rod 11 will not shake or shift during operation, so as to be able to reliably push the clamping plates 6 for clamping operation.

[0030] In the embodiment of the present utility model, the shock absorber seat 12 is fixedly connected to the telescopic end of the electric push rod 11. The shock absorber seat 12 can absorb part of the vibration generated during the pushing process of the electric push rod 11. At the same time, after the motor 4 operates to generate vibration and transmits it to the clamping plate 6 and the connecting rod 7, the shock absorber seat 12 can also play a certain shock absorption role, reducing the impact of vibration on the electric push rod 11, protecting the electric push rod 11 and increasing its service life. The connecting rod 7 is telescopically connected to the inside of the shock absorber seat 12. The connecting rod 7 telescopes within the shock absorber seat 12, so that when the motor 4 generates vibration in the left-right direction, the connecting rod 7 can transmit the vibration force to shock absorption structures such as a damper one (usually not explicitly mentioned but can be inferred) within the shock absorber seat 12. At the same time, the shock absorption structures within the shock absorber seat 12 can also transmit the reaction force to the clamping plate 6 through the connecting rod 7, thereby playing a buffering role for the motor 4 and preventing the motor 4 from continuing to move in the vibration direction. The other end of the connecting rod 7 is fixedly connected to the outer surface of the clamping plate 6. The connecting rod 7 connects the clamping plate 6 and the shock absorber seat 12, enabling the clamping plate 6 to clamp and fix the motor 4 under the action of the shock absorber seat 12 and the connecting rod 7, and transmitting the vibration force to the shock absorption structure for buffering when the motor 4 vibrates. A damper two 14 is provided at the lower end of the placement plate 5. There are several damper twos 14. The damper twos 14 at the lower end of the placement plate 5 are mainly used to reduce the vibration transmission of the motor 4 in the vertical direction. Multiple damper twos 14 can more evenly share the weight and vibration of the motor 4, improve the shock absorption effect, reduce the impact of the motor 4 vibration on the soft pad assembly and the overall heavy truck, and improve the driving stability and comfort of the heavy truck.

[0031] In the embodiment of the present utility model, the damper one 13 is arranged inside the shock absorber seat 12. One end of the damper one 13 is fixedly connected to the inner wall of the shock absorber seat 12, and the other end of the damper one 13 is fixedly connected to the connecting rod 7. When the motor 4 generates vibration in the left-right direction, the vibration force is transmitted to the connecting rod 7 through the clamping plate 6. The connecting rod 7 moves within the shock absorber seat 12, causing the damper one 13 to compress or stretch. The damper one 13 generates a reaction force through its elastic deformation, acts on the connecting rod 7, and then acts on the motor 4 through the connecting rod 7 and the clamping plate 6, playing a buffering role and preventing the motor 4 from continuing to move in the vibration direction, thereby reducing the vibration of the motor 4 in the left-right direction. A limiting block 15 is fixedly connected to the outer surface of the connecting rod 7. The limiting block 15 is slidably connected to the inner wall of the shock absorber seat 12. The function of the limiting block 15 is to limit the movement range of the connecting rod 7 within the shock absorber seat 12, prevent the connecting rod 7 from extending or retracting excessively from the shock absorber seat 12, and ensure the normal operation of the shock absorption assembly. At the same time, the limiting block 15 is slidably connected to the inner wall of the shock absorber seat 12, making the connecting rod 7 more stable during movement and ensuring that the damper one 13 can accurately play the buffering role.

[0032] In the embodiment of the present utility model, vertical rods 2 are fixedly connected to the upper end surface of the U-shaped plate 1 respectively. There are several vertical rods 2, and the vertical rods 2 play a role in connecting the U-shaped plate 1 and the mounting plate 3, providing a support structure for the whole device. Multiple vertical rods 2 can more evenly share the weight of the mounting plate 3 and the upper structure, improving the stability of the whole device. The upper end of the vertical rod 2 is fixedly connected to the mounting plate 3, and the mounting plate 3 is used to fix the whole motor mounting structure on the heavy truck. Through the threaded holes on the mounting plate 3, fasteners such as bolts can be used to firmly mount the mounting plate 3 on the bottom of the heavy truck, ensuring that the motor remains stable during vehicle driving. There are several threaded holes on the surface of the mounting plate 3, and the threaded holes provide fixed points for the mounting plate 3 to connect with the heavy truck. Through the cooperation of the bolts and the threaded holes, the mounting plate 3 can be conveniently fixed at different positions and angles to meet different installation requirements. A protective pad is provided on the upper end surface of the mounting plate 3. The protective pad can reduce the rigid contact between the mounting plate 3 and the bottom of the heavy truck, playing a role in shock absorption and buffering. During vehicle driving, the protective pad can absorb part of the vibration and impact force, reducing the vibration transmitted from the motor mounting structure to the heavy truck, and improving the driving stability and comfort of the vehicle. At the same time, the protective pad can also prevent friction and wear between the mounting plate 3 and the bottom of the heavy truck, extending the service life of the mounting components.

[0033] Working principle: First, place the motor 4 on the placement plate 5. Then, start the electric push rods 11 located at both ends of the motor 4 respectively. When the telescopic ends of the electric push rods 11 move, they will drive the shock-absorbing seat 12 to move, and the shock-absorbing seat 12 will further drive the connecting rod 7 to move, causing the connecting rod 7 to push the clamping plate 6 towards the direction of the motor 4. During this process, the guide rod 10 will slide in the guide groove 9 to play a guiding role until the clamping plates 6 at both ends contact the motor 4 respectively and clamp and fix it. By using this method, there is no need to tighten and fix with multiple bolts, thus reducing the installation time and the complexity of the operation, improving the work efficiency. Then, fix the mounting plate 3 to the bottom of the heavy truck through bolts respectively. The protective pad between the mounting plate 3 and the truck bottom can reduce the rigid contact between the mounting plate 3 and the truck bottom, reducing the risk of wear and damage of the installation components caused by vibration and impact, and completing the suspension of the motor 4. Since the connecting rod 7 is pushed and the damper 13 is in a compressed state after the clamping plate 6 clamps and fixes the motor 4, at this time, the damper 13 will exert a reaction force on the connecting rod 7. When the motor 4 generates vibrations in the left and right directions, the vibration force is first transmitted to the clamping plate 6 and then from the clamping plate 6 to the connecting rod 7. If the motor 4 vibrates to the left, the left connecting rod 7 will further compress the damper 13 on the left side, while the damper 13 on the right side in the compressed state will tend to extend, thus generating a rightward thrust on the right connecting rod 7. This thrust acts on the motor 4 through the connecting rod 7 and the clamping plate 6 to play a certain buffering role and prevent the motor 4 from continuing to move to the left; during this process, the limit block 15 slides along the inner wall of the damper 14. Similarly, if the motor 4 vibrates to the right, the right connecting rod 7 will further compress the damper 13, and the damper 13 on the left side will extend and generate a leftward thrust on the left connecting rod 7 to prevent the motor 4 from continuing to move to the right. At the same time, the damper 14 under the placement plate 5 can reduce the vibration transmission of the motor 4 in the vertical direction, which can reduce the impact of the motor 4 vibration on the soft pad assembly, extend the service life of the soft pad assembly, and ultimately improve the driving stability of the heavy truck.
