Description

Technical Field

[0001] This utility model relates to the field of motor drive technology, and in particular to a dual-motor drive device. Background Technology

[0002] Dual-motor drive is an advanced drive system that utilizes two motors working in tandem to significantly improve the performance, efficiency, and operational stability of vehicles or equipment. This technology has been widely applied in electric vehicles, power tools, and industrial equipment.

[0003] In existing motor drive technologies, dual-motor designs are often used to improve the power output and operational stability of equipment. In dual-motor drive systems, bolts are typically used to secure the motor to the industrial equipment to transmit power and enhance operational stability. However, the motors themselves are heavy, and this rigid connection method is insufficient to effectively absorb the vibration energy generated during operation. After prolonged operation, continuous vibration can easily cause the bolts to loosen. Once the bolts loosen, the drive unit may shift or even fall off unexpectedly, directly damaging the device and potentially causing a safety accident. Simultaneously, continuous vibration can also damage critical internal structures of the motor, significantly increasing the risk of fatigue fracture.

[0004] In view of the above-mentioned related technologies, this application provides a dual-motor drive device with high support stability. Utility Model Content

[0005] In order to effectively improve the support stability of a dual-motor drive device, this application provides a dual-motor drive device.

[0006] This application provides a dual-motor drive device, which adopts the following technical solution:

[0007] A dual-motor drive device includes a mounting frame and a motor assembly mounted on the mounting frame. The motor assembly includes two drive motors arranged opposite each other and mounted on the mounting frame. It also includes a support rod assembly mounted on the mounting frame for supporting the motor assembly. The support rod assembly includes at least two support rods mounted on the mounting frame and a support base mounted between the drive motors and the support rods for supporting the drive motors.

[0008] By adopting the above technical solution, a support rod assembly is set on the mounting frame to support the motor assembly. The drive motor is supported by at least two support rods and a support seat installed between the support rods and the drive motor. This can enhance the support force on the drive motor, reduce the adverse effects caused by the inability of rigid connections to absorb vibration energy, and also prevent bolts from loosening and the device from falling off, thus effectively improving the support stability of the dual-motor drive device.

[0009] Optionally, one end of the support rod is provided with a first limiting post, and the mounting frame is provided with a limiting hole corresponding to the first limiting post; the other end of the support rod is provided with a first supporting threaded hole, and the mounting frame is provided with a second supporting threaded hole corresponding to the first supporting threaded hole; a support bolt for locking the support rod and the mounting frame is installed between the first supporting threaded hole and the second supporting threaded hole.

[0010] By adopting the above technical solution, the support rod and the mounting frame can be initially positioned by using the first limiting post and the limiting hole. Then, the support bolts are used to lock the two by passing through the first support threaded hole and the second support threaded hole, which ensures the stability of the connection between the support rod and the mounting frame, thereby effectively improving the support stability of the dual motor drive device.

[0011] Optionally, the support base has a first mounting threaded hole, and the housing of the drive motor has a second mounting threaded hole corresponding to the first mounting threaded hole. A fastening bolt for locking the support base and the drive motor is installed between the first mounting threaded hole and the second mounting threaded hole.

[0012] By adopting the above technical solution, the support base and the mounting threaded hole of the drive motor housing are connected by fastening bolts, so that the support base can stably support the drive motor, thereby further improving the support stability of the dual-motor drive device.

[0013] Optionally, the bottom of the support base is provided with a first limiting groove that cooperates with the support rod.

[0014] By adopting the above technical solution, a first limiting groove that matches the support rod is provided at the bottom of the support base, which can ensure that the support base and the support rod are accurately installed and positioned.

[0015] Optionally, the top of the support base is provided with a second limiting slot that cooperates with the drive motor.

[0016] By adopting the above technical solution, the top of the support base is provided with a second limiting slot that cooperates with the drive motor, which can better position and support the drive motor, and further improve the support stability of the drive motor.

[0017] Optionally, a dust cover assembly is also included; the dust cover assembly includes a dust cover bracket installed on the outside of the drive motor, an L-shaped dust cover housing installed on the dust cover bracket, a dust cover installed on one end of the drive motor, and a dust cover mounting base installed between the top of the drive motor and the dust cover bracket.

[0018] The specific structure of the dust cover assembly is disclosed by adopting the above technical solution. By setting up the dust cover assembly, dust can be prevented from entering the drive motor, protecting the internal structure of the motor from dust damage and extending the service life of the motor.

[0019] Optionally, the dustproof mounting base has a dustproof groove that mates with the drive motor; the dustproof mounting base has a plurality of first dustproof threaded holes, the dustproof bracket has a second dustproof threaded hole corresponding to the first dustproof threaded hole, and the housing of the drive motor has a third dustproof threaded hole corresponding to the first dustproof threaded hole; a first locking bolt and a first locking nut are installed between the first dustproof threaded hole, the second dustproof threaded hole and the third dustproof threaded hole.

[0020] By adopting the above technical solution, a dustproof mounting base with a dustproof groove that mates with the drive motor is installed, and corresponding first, second, and third dustproof threaded holes are opened. The first locking bolt and the first locking nut are used for installation and fixation, which can make the dustproof mounting base firmly installed on the drive motor. This ensures that the L-shaped dustproof housing can be stably installed on the outside of the drive motor, achieving a good dustproof effect.

[0021] Optionally, the dustproof bracket has multiple fourth dustproof threaded holes, the L-shaped dustproof housing has a fifth dustproof notch corresponding to the fourth dustproof threaded holes, and the dustproof end cap has a sixth dustproof threaded hole corresponding to the fourth dustproof threaded holes; a second locking bolt is installed between the fourth dustproof threaded holes, the fifth dustproof notch, and the sixth dustproof threaded holes.

[0022] By adopting the above technical solution, using the fourth dustproof threaded hole, the fifth dustproof notch and the sixth dustproof threaded hole, and using the second locking bolt to connect the dustproof bracket, the L-shaped dustproof housing and the dustproof end cover together, the dustproof cover assembly can be effectively installed, preventing dust from entering the drive motor, protecting the key internal structure of the motor, reducing the probability of failure and damage caused by dust, and improving the reliability and service life of the drive motor.

[0023] Optionally, it also includes a rope guide installed on the mounting frame, wherein the rope guide has a rope guide hole in the middle; the inner surface of the rope guide hole is provided with a guide arc surface.

[0024] By adopting the above technical solution, a rope guide is installed on the mounting frame, and a rope guide hole is opened in the middle of the rope guide, and the inner surface of the rope guide hole has a guide arc surface, which can guide the rope to pass through, reduce the friction and wear between the rope and the rope guide, and improve the smoothness of the rope movement, thereby improving the stability of the dual motor drive device.

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0040] This application discloses a dual-motor drive device. (Refer to...) Figure 1 A dual-motor drive device includes a mounting frame 1, a motor assembly 2 mounted on the mounting frame 1, a support rod assembly 3 mounted on the mounting frame 1 for supporting the motor assembly 2, a dust cover assembly 4 mounted on the outside of the motor assembly 2, and a rope guide assembly 5 mounted on the mounting frame 1. The motor assembly 2 includes two drive motors 21 arranged opposite each other and mounted on the mounting frame 1.

[0041] Reference Figure 1 The support rod assembly 3 includes at least two support rods 31 mounted on the mounting frame 1 and a support base 32 mounted between the drive motor 21 and the support rods 31 for supporting the drive motor 21.

[0042] Reference Figure 1 and Figure 2 The support rod 31 has a first limiting post 311 at one end, and the mounting frame 1 has a limiting hole 11 corresponding to the first limiting post 311. Both the support rod 31 and the first limiting post 311 are made of steel, which has high hardness to ensure accurate support and positioning. The shape of the limiting hole 11 matches the first limiting post 311, and the two fit tightly together to prevent the support rod 31 from swaying in the horizontal direction.

[0043] Reference Figure 1 and Figure 2The other end of the support rod 31 is provided with a first support threaded hole 312, and the mounting frame 1 is provided with a second support threaded hole 12 corresponding to the first support threaded hole 312. A support bolt 313 for locking the support rod 31 and the mounting frame 1 is installed between the first support threaded hole 312 and the second support threaded hole 12. After the support bolt 313 is tightened, the support rod 31 can be firmly fixed on the mounting frame 1.

[0044] Reference Figure 3 and Figure 4 The support base 32 has a first mounting threaded hole 321, and the housing of the drive motor 21 has a second mounting threaded hole 211 corresponding to the first mounting threaded hole 321. A fastening bolt 322 for locking the support base 32 and the drive motor 21 is installed between the first mounting threaded hole 321 and the second mounting threaded hole 211. After the fastening bolt 322 is tightened, the support base 32 and the drive motor 21 are connected together. The bottom of the support base 32 has a first limiting groove 323 that cooperates with the support rod 31. The first limiting groove 323 is generally a semi-circular groove that can just hold the support rod 31 to prevent the support base 32 from sliding on the support rod 31. The top of the support base 32 has a second limiting groove 324 that cooperates with the drive motor 21. The shape of the second limiting groove 324 is adapted to the housing of the drive motor 21, which can better fix the drive motor 21 and also play a certain buffering role to reduce the vibration transmission of the drive motor 21. In this embodiment, there are two of each of the first mounting threaded hole 321, the second mounting threaded hole 211, and the fastening bolt 322.

[0045] Reference Figure 5 The dust cover assembly 4 includes a dust cover bracket 41 installed on the outside of the drive motor 21, an L-shaped dust cover 42 installed on the dust cover bracket 41, a dust cover 43 installed on one end of the drive motor 21, and a dust cover mounting seat 44 installed between the top of the drive motor 21 and the dust cover bracket 41.

[0046] Reference Figure 5 and Figure 6The dustproof mounting base 44 has a dustproof groove 441 that mates with the drive motor 21. The shape of the dustproof groove 441 is adapted to the top of the drive motor 21 for better fit. The dustproof mounting base 44 has multiple first dustproof threaded holes 442, the dustproof bracket 41 has second dustproof threaded holes 411 corresponding to the first dustproof threaded holes 442, and the housing of the drive motor 21 has third dustproof threaded holes 212 corresponding to the first dustproof threaded holes 442. A first locking bolt 443 and a first locking nut 444 are installed between the first dustproof threaded holes 442, the second dustproof threaded holes 411, and the third dustproof threaded holes 212. By tightening the first locking bolt 443 and the first locking nut 444, the dustproof mounting base 44, the dustproof bracket 41, and the drive motor 21 are connected together.

[0047] Reference Figure 5 and Figure 7 The dustproof bracket 41 has multiple fourth dustproof threaded holes 412, the L-shaped dustproof housing 42 has a fifth dustproof notch 421 corresponding to the fourth dustproof threaded holes 412, and the dustproof end cap 43 has a sixth dustproof threaded hole 431 corresponding to the fourth dustproof threaded holes 412. A second locking bolt 413 is installed between the fourth dustproof threaded holes 412, the fifth dustproof notch 421, and the sixth dustproof threaded hole 431. Similarly, tightening the second locking bolt 413 connects the dustproof bracket 41, the L-shaped dustproof housing 42, and the dustproof end cap 43 together. This forms a relatively enclosed space, effectively preventing dust from entering the drive motor 21, protecting the motor's internal critical structures, reducing the probability of malfunctions and damage caused by dust, and improving the reliability and service life of the drive motor 21.

[0048] Reference Figure 5 and Figure 8 In addition, the dustproof bracket 41 is provided with multiple seventh dustproof threaded holes 414, and the L-shaped dustproof housing 42 is provided with an eighth dustproof threaded hole 423 corresponding to the seventh dustproof threaded holes 414. A third locking bolt 422 for locking the L-shaped dustproof housing 42 and the dustproof bracket 41 is installed between the seventh dustproof threaded holes 414 and the eighth dustproof threaded holes 423. Similarly, tightening the third locking bolt 422 locks the dustproof bracket 41 and the L-shaped dustproof housing 42 into a whole and installs them on the outside of the two drive motors 21, which improves the structural compactness of the entire device.

[0049] Reference Figure 1 and Figure 9 The rope guide assembly 5 includes a rope guide 51 mounted on the mounting frame 1 and a winch 52 mounted on the mounting frame 1.

[0050] Reference Figure 1 and Figure 9The rope guide 51 is mounted on the mounting frame 1, and the rope guide 51 has a rope guide hole 511. The rope guide 51 is mounted on the mounting frame 1 by screws. Furthermore, the inner surface of the rope guide hole 511 has a guide arc surface 5111. The guide arc surface 5111 allows the rope to pass through the rope guide hole 511 more smoothly, reducing friction and wear. The rope guide 51 is made of wear-resistant material, such as engineering plastics.

[0051] The implementation principle of a dual-motor drive device according to an embodiment of this application is as follows: A dual-motor drive device includes a mounting frame 1, two opposing drive motors 21 mounted on the mounting frame 1, at least two support rods 31 mounted on the mounting frame 1, and a support seat 32 installed between the drive motors 21 and the support rods 31; by using at least two support rods 31 and the support seat 32 installed between the support rods 31 and the drive motors 21 to support the drive motors 21, the support force on the drive motors 21 can be enhanced, the adverse effects caused by the inability of rigid connections to absorb vibration energy can be reduced, and the loosening of bolts and displacement of the device can be avoided, thereby effectively improving the support stability of the dual-motor drive device.
