[0002] As a core driving component of modern industrial and automated equipment, the reliability, maintainability, and adaptability of electric motors are increasingly valued. Traditional motors typically employ an integral or non-modular design, with the drive motor, housing, and transmission mechanism often fixedly connected. When maintenance, repair, or replacement is required, the entire motor often needs to be disassembled, a cumbersome, time-consuming, and labor-intensive process that can easily cause wear to critical structures such as the main housing threads and positioning references, affecting equipment accuracy and lifespan. The disadvantages of traditional structures are particularly pronounced in applications requiring frequent maintenance or rapid motor replacement to adapt to different operating conditions. Therefore, the industry urgently needs a new type of motor housing structure that enables rapid disassembly and modular replacement of the drive motor, significantly improving maintenance efficiency and system adaptability while ensuring connection rigidity and sealing, and reducing total lifecycle costs. Utility Model Content

The housing includes a main housing, a fixing element, and an end cover. The end cover is disposed at one end of the main housing and forms an installation cavity. The fixing element is used to fix the end cover to one end of the main housing. The first base is disposed at the port of the installation cavity. The second base is used to fix the drive motor to the first base. The transmission component is disposed on the first base, and the drive motor is drivenly connected to the transmission component.

[0005] A further improvement to the above scheme is that the inner circumference of the main housing is provided with a quick-release connection part, a transmission connection part and a sealing connection part in sequence along the axial direction; the end cover is provided with an insertion part, which is located in the quick-release connection part; the transmission connection part is used to connect the transmission assembly; and the sealing connection part is provided with a sealing element for sealing between the first base and the main housing.

[0006] A further improvement to the above scheme is that the mounting cavity is provided with a first step and a second step. The first step is located on the inner circumference of the insertion part, and the second step is located between the sealing connection part and the transmission connection part. The first step is provided with a first bearing, and the second step is provided with a second bearing. Both the first bearing and the second bearing are connected to the first base.

[0007] A further improvement to the above scheme is that the outer periphery of the main housing is provided with an assembly hole, the insertion part is provided with an alignment hole, the assembly hole and the alignment hole are opposite to each other, and the fixing element is used to connect the insertion hole and the assembly hole.

[0008] A further improvement to the above solution is that the fixing element is a pin or a screw.

[0009] A further improvement to the above scheme is that the end of the insertion part is provided with an insertion slope, and the outer periphery of the insertion part is provided with a clearance groove.

[0010] A further improvement to the above solution is that the end cap is a metal end cap used for heat dissipation of the drive motor.

[0011] A further improvement to the above solution is that the first base extends toward the drive motor with heat dissipation ribs, and thermal grease is provided between the heat dissipation ribs and the stator winding of the drive motor to conduct and dissipate heat from the stator winding.

[0014] The beneficial effects of this utility model are: Compared to existing motor housings, this invention improves the efficiency and convenience of motor assembly and maintenance. By fixing the drive motor to an independently set second base and mounting the second base entirely on the first base, modularization of the drive motor and its transmission mechanism is achieved. During maintenance or replacement, there is no need to disassemble the main housing or complex transmission system; simply disconnecting the second base from the first base allows for quick removal of the entire drive motor, greatly simplifying the operation process and saving time and labor costs. The first base is fixedly set at the port of the mounting cavity formed by the end cover and the main housing, providing a stable mounting reference for the transmission components and drive motor, effectively resisting vibration and impact during operation, and ensuring accurate and smooth power transmission. The end cover is reliably connected to the main housing through fixing elements, ensuring the overall sealing and protection level of the housing. The quick-release structure modularizes the drive motor unit, allowing the same model of main housing and transmission mechanism to be easily adapted to drive motors of different power or model; only the corresponding second base module needs to be replaced, improving the flexibility and scalability of the product series and reducing R&D and inventory costs.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-4As shown, in one embodiment of this utility model, a quick-release structure for a motor housing is provided, including a housing 1, a first base 2, a transmission assembly 3, a second base 4, and a drive motor 5. The housing 1 includes a main housing 11, a fixing element 12, and an end cap 13. The end cap 13 is disposed at one end of the main housing 11 and forms an installation cavity 14. The fixing element 12 is used to fix the end cap 13 to one end of the main housing 11. The first base 2 is disposed at the port of the installation cavity 14. The second base 4 is used to fix the drive motor 5 to the first base 2. The transmission assembly 3 is disposed on the first base 2, and the drive motor 5 is drivenly connected to the transmission assembly 3. This embodiment improves the efficiency and convenience of motor assembly and maintenance. By fixing the drive motor 5 to the independently disposed second base 4 and installing the second base 4 as a whole on the first base 2, the modularity of the drive motor 5 and its transmission mechanism is realized. During maintenance or replacement, there is no need to disassemble the main housing 11 or the complex transmission system. Simply disconnecting the second base 4 from the first base 2 allows the drive motor 5 to be quickly removed as a whole, greatly simplifying the operation process and saving time and labor costs. The first base 2 is fixedly installed at the port of the mounting cavity 14 formed by the end cover 13 and the main housing 11, providing a stable mounting reference for the transmission assembly 3 and the drive motor 5, effectively resisting vibration and impact during operation, and ensuring accurate and smooth power transmission. The end cover 13 is reliably connected to the main housing 11 through the fixing element 12, ensuring the overall sealing and protection level of the housing 1. The quick-release structure modularizes the drive motor 5 unit, allowing the same model of main housing 11 and transmission mechanism to be easily adapted to drive motors 5 of different power or model. Only the corresponding second base 4 module needs to be replaced, improving the flexibility and scalability of the product series and reducing R&D and inventory costs. The modular design avoids frequent disassembly and assembly of the main structure, reduces wear on key parts such as the threads and positioning surfaces of the main housing 11, and extends the service life of the main structure. At the same time, partial maintenance and replacement become more economical. This embodiment optimizes the product's maintainability, improves structural stability and configuration flexibility, and has excellent overall performance, making it highly practical and competitive in the market.

[0020] The inner circumference of the main housing 11 is axially arranged with a quick-release connecting part 111, a transmission connecting part 112, and a sealing connecting part 113. The end cap 13 is provided with an insertion part 131, which is located within the quick-release connecting part 111. The transmission connecting part 112 is used to connect the transmission assembly 3. The sealing connecting part 113 is provided with a seal for sealing between the first base 2 and the main housing 11. In this embodiment, through axial modular partitioning design, the physical isolation and sequential implementation of the three core functions of installation guidance, power transmission, and environmental sealing are achieved. The end cap 13, through the cooperation of the insertion part 131 and the quick-release connecting part 111, can achieve rapid preliminary positioning and installation, greatly simplifying the assembly steps and improving production efficiency. The transmission connecting part 112 provides a proprietary, high-rigidity installation and support interface for the transmission assembly 3, ensuring the accuracy and stability of the power transmission path, effectively reducing vibration and noise during operation, and improving the reliability of the transmission.

[0021] The mounting cavity 14 is provided with a first step 141 and a second step 142. The first step 141 is located on the inner circumference of the insertion part 131, and the second step 142 is located between the sealing connection part 113 and the transmission connection part 112. The first step 141 is provided with a first bearing 143, and the second step 142 is provided with a second bearing 144. Both the first bearing 143 and the second bearing 144 are connected to the first base 2. In this embodiment, the first step 141 is located on the inner circumference of the insertion part 131, and the second step 142 is located between the sealing connection part 113 and the transmission connection part 112. The two are distributed axially at intervals, forming two-point support for the first base 2. This enhances the overall rigidity of the first base 2 and its transmission assembly 3, effectively suppressing the radial runout and flexural deformation of the shaft during high-speed operation, and ensuring transmission accuracy and stability. The two-step structure provides accurate axial mounting positioning surfaces for the first bearing 143 and the second bearing 144, ensuring precise control of bearing preload and consistent installation. The first base 2, by engaging with the inner rings of the two bearings, also achieves precise axial positioning, simplifying the overall assembly and debugging process.

[0022] The main housing 11 has an assembly hole 114 on its outer periphery, and the insertion part 131 has an alignment hole 132. The assembly hole 114 and the alignment hole 132 are opposite each other, and the fixing element 12 is used to connect the insertion hole and the assembly hole 114. Specifically, the fixing element 12 is a pin or a screw. In this embodiment, the assembly hole 114 and the alignment hole 132 cooperate with each other to provide precise radial and circumferential positioning for the connection between the end cover 13 and the main housing 11. The hole-shaft cooperation method ensures the uniqueness and accuracy of the installation position of the end cover 13, prevents the end cover 13 from shifting or rotating during operation, and ensures the sealing of the installation cavity 14 and the alignment of the internal components. Using a pin or screw as the fixing element 12, fastening or disassembly can be easily completed using conventional tools without special tooling. This simplifies the installation and subsequent maintenance process of the end cover 13, perfectly matching the design intention of this quick-release structure to pursue convenient maintenance.

[0023] The insertion part 131 has an insertion ramp 133 at its end, and an anti-cavity groove is provided on the outer periphery of the insertion part 131. In this embodiment, the insertion ramp 133 forms a guide cone surface. In the initial stage of inserting the end cap 13 into the main housing 11, the ramp can automatically correct the slight coaxiality deviation between the end cap 13 and the opening of the main housing 11. Even if there is a certain centering error, the wedge effect of the ramp can be used to smoothly insert the end cap 13, effectively avoiding damage or jamming of parts caused by hard collisions during assembly, greatly reducing assembly difficulty and improving assembly efficiency.

[0024] End cap 13 is a metal end cap 13 used for heat dissipation of the drive motor 5. In this embodiment, the metal material (such as aluminum alloy, copper alloy or other metals with good thermal conductivity) has excellent thermal conductivity. As an important component of the motor housing 1, the metal end cap 13 can efficiently and quickly conduct the heat generated by the internal windings, iron core, etc. of the motor during operation to the end cap 13 body, and exchange heat with the outside air through convection on its outer surface (especially when heat dissipation fins are added or it is in a cooling air duct), which greatly enhances the heat dissipation capacity of the entire motor system, effectively reduces the internal operating temperature, ensures the continuous and stable operation of the motor under high load, and extends the service life of insulation materials and bearings and other components.

[0025] The first base 2 extends towards the drive motor 5 with heat dissipation ribs 21. Thermally conductive silicone grease is applied between the heat dissipation ribs 21 and the stator windings of the drive motor 5 to conduct and dissipate heat from the stator windings. In this embodiment, the heat dissipation ribs 21 extend directly inward from the first base 2, which is part of the motor's main housing 11, physically approaching or even contacting the stator windings, the largest heat source inside the motor. By filling with high-performance thermally conductive silicone grease, the air gap between the heat dissipation ribs 21 and the windings (or their thermally conductive components) is effectively eliminated, significantly reducing contact thermal resistance and creating a low-thermal-resistance, high-efficiency heat conduction channel from the core of the heat source to the external heat dissipation base. This greatly improves the heat dissipation conditions of the stator windings. It can quickly conduct the Joule heat generated by the windings to the second base 4 or the first base 2, which has a larger heat dissipation surface area, thereby effectively suppressing the internal temperature rise of the motor.

[0026] The first base 2 is provided with a fixed connecting end 22, and the second base 4 is provided with a connecting boss 41. The connecting boss 41 is disposed on the fixed connecting end 22, which is composed of multiple connecting ribs 221. An assembly groove is formed between the multiple connecting ribs 221, and the connecting boss 41 is disposed on the assembly groove. Connecting holes are provided on the connecting ribs 221 for inserting screws to fix the connecting boss 41. In this embodiment, the multiple connecting ribs 221 are spaced apart, forming a stable support frame. The connecting boss 41 is embedded in the assembly groove formed by these ribs, achieving multi-directional positioning and constraint, effectively resisting torque and shear force in various directions. The connecting boss 41 is pressed and fixed by screws passing through the connecting holes on the connecting ribs 221, forming a strong mechanical connection. This greatly improves the connection rigidity and overall structural stability between the first base 2 and the second base 4, ensuring the reliability of the connection part under motor vibration during operation. The design of the connection boss 41 and the assembly groove itself has a guiding and preliminary positioning function. During assembly, the boss easily slides into the groove, naturally correcting the relative position between the two bases and achieving rapid initial alignment. This simplifies the assembly process, reduces the demanding skill requirements on operators, and improves assembly efficiency, making it ideal for scenarios requiring repeated assembly and disassembly in quick-release structures. The design of multiple connecting stiffeners 221 and multiple screw fastening points ensures that the locking force and working load are evenly distributed across a large contact area and multiple connection points. This avoids stress concentration, reduces the risk of overloading at individual connection points, and thus improves long-term fatigue strength and connection reliability.

[0027] The drive motor 5 is equipped with an output shaft 51, one end of which passes through the second base 4 and extends to the first base 2 to connect with the transmission assembly 3. In this embodiment, the output shaft 51 directly passes through the second base 4 and extends to the first base 2 to connect with the transmission assembly 3, forming a nearly straight power transmission path. This shortens the transmission chain from the motor rotor to the external actuator, reduces intermediate links and potential power losses, improves the efficiency of power transmission, and also helps to reduce system inertia and improve the dynamic response speed of the motor.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
