Description

Technical Field

[0001] The utility model relates to the field of gear box motor structures, in particular to an axially limited gear box motor structure. Background Art

[0002] In the process of assembling the seat motor, a combination of bolts and screws is usually used to achieve a stable connection between the motor and the box base. Specifically, the box base is first fixed to the seat or other supporting structure by bolts, and then the motor is placed on the box base. In order to ensure the stability of the motor, it is also necessary to use screws to install the baffle at the corresponding position of the box base to achieve the purpose of fixing the motor.

[0003] However, this traditional limiting structure has the following significant disadvantages:

[0004] 1. The traditional limit structure requires additional fasteners such as bolts and screws, which not only increases the number of parts and costs, but also has the risk of loosening due to insufficient tightening, as the tightness of the bolts and screws may be affected by human operation. Once the fasteners are loose, the stability of the motor will be seriously affected, and may even cause the motor to fall.

[0005] 2. If the baffle is not installed or installed loosely, the motor is at risk of falling, which may not only damage the motor itself, but also cause safety hazards to the surrounding environment and personnel.

[0006] 3. As multiple parts and steps are required to complete the assembly of the motor, the traditional limit structure increases the manufacturing process. This not only increases the complexity of production, but may also lead to longer production cycles and reduced production capacity. In addition, multiple assembly steps also increase the possibility of errors, further affecting the quality and reliability of the product. Summary of the invention

[0007] In order to solve the above problems, the utility model provides an axially limited gearbox motor structure. After the motor body is installed at the specified position, it only needs to be rotated a certain angle to achieve a tight connection between the motor box and the box base. This design ensures that the motor will not fall, and at the same time, no additional fasteners or tools are required, which simplifies the assembly process and reduces the assembly cost. The overall solution improves the overall structural reliability between the motor box and the box base through precise matching and stable connection.

[0008] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an axially limited gearbox motor structure, including a motor case and a case base, wherein the motor case includes a mounting portion, the case base is provided with a mounting notch for the mounting portion to enter, the outer side of the mounting portion is convexly provided with a mounting protrusion, the inner wall of the mounting notch is provided with a first mounting groove adapted to the mounting protrusion, and the inner wall of the mounting notch is also provided with a second mounting groove located on one side of the first mounting groove and connected to the first mounting groove, the mounting portion of the motor case is inserted into the mounting notch, and the mounting protrusion is aligned with the first mounting groove, and at the same time the mounting protrusion moves along the direction of the first mounting groove to the position of the second mounting groove, and the motor case is rotated so that the mounting protrusion is stuck in the position of the second mounting groove.

[0009] Furthermore, the box base is provided with a plurality of fixing holes which penetrate the box base from top to bottom.

[0010] Furthermore, a plurality of positioning columns are protruding from the top of the box base.

[0011] Furthermore, first axial clearance holes aligned with each other are provided on both sides of the box base.

[0012] Furthermore, the motor housing also includes a fixing portion which is integrally formed with the mounting portion and is located at the bottom of the mounting portion, wherein a plurality of screw holes for connecting with the motor are provided at the bottom of the fixing portion.

[0013] Furthermore, a transmission cavity and a transmission shaft cavity for mounting the output shaft of the power supply machine are arranged in the mounting portion, wherein the transmission shaft cavity is communicated with the fixing portion.

[0014] Furthermore, second axial clearance holes communicating with the transmission cavity are arranged on both sides of the outer surface of the fitting part. When the fitting part and the box base are fitted in place, the first axial clearance hole is aligned with the second axial clearance hole.

[0015] Furthermore, when the fitting protrusion slides to the end of the second sliding slot, the contact area between the fitting protrusion and the second sliding slot is at least 1 / 2 of the surface area of ​​the fitting protrusion.

[0016] The beneficial effect of the utility model is that the matching between the box base and the matching protrusion is used to limit the position, thereby ensuring a stable connection between the motor box and the box base.

DETAILED DESCRIPTION

[0025] See also Figure 1-7As shown, the utility model relates to an axially limited gearbox motor structure, including a motor case 1 and a case base 2, wherein a mounting portion 11 is arranged on the top of the motor case 1, wherein the case base 2 is provided with a mounting notch 26 for the mounting portion 11 to enter, wherein a mounting protrusion 111 is convexly provided on the outer side of the mounting portion 11, wherein the inner wall of the mounting notch 26 is provided with a first mounting slot 24 adapted to the mounting protrusion 111, and the inner wall of the mounting notch 26 is further provided with a second mounting slot 25 located on one side of the first mounting slot 24 and connected to the first mounting slot 24, the mounting portion 11 of the motor case 1 is inserted into the mounting notch 26, and the mounting protrusion 111 is aligned with the first mounting slot 24, and at the same time, the mounting protrusion 111 moves along the direction of the first mounting slot 24 to the position of the second mounting slot 25, and the motor case 1 is rotated so that the mounting protrusion 111 is stuck in the position of the second mounting slot 25.

[0026] Compared with the traditional bolt fastening method, this structure greatly simplifies the installation steps and improves the installation efficiency by matching the mounting protrusion 111 with the mounting slot. Improved stability: The mounting protrusion 111 moves in the first mounting slot 24 and is finally stuck in the position of the second mounting slot 25. This design effectively prevents the motor 3 from shaking back and forth and improves the stability of the entire structure. In addition, through the integrated design, the use of additional fasteners (such as bolts, screws, etc.) is reduced, which reduces costs and reduces the risks caused by loose fasteners. Since the mounting protrusion 111 will eventually be stuck in the position of the second mounting slot 25, even before it is completely fixed, the motor housing 1 will not fall easily, reducing the operational risk.

[0027] Furthermore, a plurality of fixing holes 22 are provided at the edge of the box base 2, which penetrate the box base 2 from top to bottom. (For use in mounting with bolts and corresponding mounting surfaces)

[0028] By opening a fixing hole 22 that runs through the box base 2 from top to bottom and fixing the box base 2 to the seat mounting surface with fasteners such as bolts, the stability and reliability of the installation can be greatly enhanced. A stable installation can reduce the vibration and noise generated by the motor 3 during operation, and improve the performance of the motor 3 and the user's experience.

[0029] Furthermore, a plurality of positioning columns 21 are convexly provided on the top of the box base 2. The function of the positioning columns 21 is to facilitate quick positioning with the mounting surface, and omit the alignment of the holes between the fixed mounting holes 22 and the mounting surface. The positioning columns 21 can be quickly aligned with the corresponding holes on the mounting surface, which greatly simplifies the installation process and saves time. The precise alignment of the positioning columns 21 with the holes can ensure the installation accuracy between the box base 2 and the mounting surface, and reduce performance problems caused by installation errors. The design of the positioning columns 21 can significantly reduce rework caused by installation errors and improve work efficiency.

[0030] Furthermore, first axial clearance holes 23 aligned with each other are provided on both sides of the box base 2. First axial clearance holes 23 aligned with each other are specially designed on both sides of the box base 2. The purpose of these clearance holes is to meet the needs of another longitudinally arranged screw rod in the overall device. The screw rod needs to pass through these clearance holes to connect with the motor 3. With such a design, the screw rod can drive the corresponding seat to move forward and backward through the control of the motor 3. Such a design brings several significant advantages: first, it improves the compatibility and versatility of the equipment, because screw rods of different sizes and layouts can pass through these clearance holes smoothly; second, the installation process becomes more convenient, and the screw rod can directly pass through the clearance hole to connect with the motor 3 without complicated steps; third, the connection between the screw rod and the motor 3 ensures the stability and reliable movement of the seat; finally, when the motor 3, screw rod and other components need to be repaired or replaced, they can be easily removed from the clearance hole, simplifying the maintenance process.

[0031] Furthermore, the motor housing 1 further comprises a fixing portion 12 which is integrally formed with the fitting portion 11 and is located at the bottom of the fitting portion 11 , wherein a plurality of screw holes 121 for connecting with the motor 3 are provided at the bottom of the fixing portion 12 .

[0032] In the design of the motor housing 1, we have specially added a fixing portion 12 that is integrally formed with the mounting portion 11. This fixing portion 12 is located at the bottom of the mounting portion 11, and is provided with a number of screw holes 121, which are specifically used to connect the motor 3. This design makes the installation of the motor 3 extremely simple and stable. In the actual installation process, the staff only needs to tightly connect the motor 3 with the screw holes 121 of the fixing portion 12 through fasteners such as screws to easily complete the installation of the motor 3. This installation method not only improves work efficiency, but also ensures a stable connection between the motor 3 and the housing, and reduces the shaking or displacement that may occur in the motor 3 during operation.

[0033] Furthermore, a transmission cavity 114 is provided in the fitting portion 11; a transmission cavity 114 is provided on the inner wall of the fitting portion 11. The transmission cavity 114 is an important component inside the motor housing 1, and plays a key role in transmitting the power of the motor 3 to the external device. The design of the transmission cavity 114 needs to ensure sufficient strength to withstand the force and vibration generated when the motor 3 is running.

[0034] Furthermore, a transmission shaft cavity 113 connected to the transmission cavity 114 is also provided in the fitting portion 11. The transmission shaft cavity 113 is used to assemble the output shaft of the motor 3. The output shaft of the motor 3 is a bridge between the motor 3 and the transmission system, and is responsible for converting the rotational motion of the motor 3 into linear motion or torque output. The design of the transmission shaft cavity 113 needs to ensure accurate matching with the output shaft of the motor 3 to reduce energy loss and friction resistance during the transmission process and improve transmission efficiency.

[0035] Furthermore, second axial clearance holes 112 communicating with the transmission cavity 114 are provided on both sides of the outer surface of the fitting portion 11. When the fitting portion 11 and the box base 2 are fitted in place, the first axial clearance hole 23 is aligned with the second axial clearance hole.

[0036] In addition, second axial clearance holes 112 connected to the transmission cavity 114 are also provided on both sides of the outer surface of the mounting portion 11. These clearance holes are designed to facilitate the connection or interaction between external equipment or transmission mechanisms and the transmission components inside the transmission cavity 114. When the mounting portion 11 and the box base 2 are mounted in place, the first axial clearance hole 23 (the hole mentioned above for the screw rod to pass through) and the second axial clearance hole 112 will be aligned to form a connected channel. In this way, the external equipment or transmission mechanism can be connected to the transmission components inside the transmission cavity 114 through this channel to achieve power transmission.

[0037] Specific working principle:

[0038] When the motor housing 1 and the housing base 2 are assembled, the working principle is as follows:

[0039] The top of the motor housing 1 is designed with a fitting portion 11, and a fitting protrusion 111 is convexly provided on the outer side of the fitting portion 11. The housing base 2 is provided with a fitting notch 26, and the inner wall of the notch is provided with a first fitting slot 24 adapted to the fitting protrusion 111, and a second fitting slot 25 connected to the first fitting slot 24 and located on one side thereof.

[0040] First, the fitting portion 11 of the motor housing 1 is inserted into the fitting notch 26 of the housing base 2, while ensuring that the fitting protrusion 111 is aligned with the first fitting slot 24. Then, the fitting portion 11 moves along the direction of the first fitting slot 24 until the fitting protrusion 111 reaches the end of the slot, at which time the fitting protrusion 111 enters the position of the second fitting slot 25 connected to the first fitting slot 24. (In this process, the outer contour of the fitting protrusion 111 matches the inner wall contour of the first fitting slot 24, ensuring that the fitting protrusion 111 can slide smoothly along the direction of the first fitting slot 24. This matching design not only ensures the smoothness of sliding, but also improves the accuracy and stability of fitting.)

[0041] Next comes the critical rotation step. The user needs to rotate the motor housing 1 so that the fitting protrusion 111 transitions from the first fitting slot 24 to the second fitting slot 25, and finally gets stuck in the position of the second fitting slot 25. (The inner wall profile of the second fitting slot 25 matches the motion trajectory of the fitting protrusion 111 during rotation, ensuring that the fitting protrusion 111 can smoothly rotate along the predetermined path and finally get stuck in the predetermined position of the second fitting slot 25.) This rotation action not only ensures a stable connection between the motor housing 1 and the housing base 2, but also aligns the second axial clearance holes 112 provided on both sides of the outer surface of the fitting portion 11 with the first axial clearance holes 23 on the housing base 2. Moreover, when the motor 3 is installed in the housing base 2 and rotated to the extreme angle (i.e., the fitting protrusion 111 reaches the end of the second sliding slot), the design ensures that at least 1 / 2 of the contact area of ​​the fitting protrusion 111 is located in the second sliding slot. This design ensures a stable connection between the motor housing 1 and the housing base 2, and effectively prevents the motor 3 from accidentally falling off or shaking during operation. At the same time, it also enhances the stability of the overall structure and improves the operational reliability of the equipment. This design not only simplifies the assembly process, but also reduces the assembly cost, bringing users a more convenient and efficient use experience.

[0042] The two aligned clearance holes "the first axial clearance hole 23 and the second axial clearance hole 112" form a connected channel. This channel provides a connection interface for external equipment or transmission mechanism to the transmission cavity 114 inside the motor housing 1. For example, a screw rod or other transmission components can pass through the two aligned clearance holes into the transmission cavity 114 and connect with the output shaft of the motor 3 to achieve power transmission. At the same time, the transmission cavity 114 on the inner wall of the mounting portion 11 and the transmission shaft cavity 113 in the fixing portion 12 provide precise mounting space for the output shaft of the motor 3. The output shaft of the motor 3 is mounted in the transmission shaft cavity 113 and is connected to other transmission components through the transmission cavity 114, thereby achieving power transmission.

[0043] The advantages of the overall solution are mainly reflected in the following aspects:

[0044] It cleverly utilizes the fitting between the box base 2 and the fitting protrusion 111 to limit the position, thereby ensuring a stable connection between the motor box 1 and the box base 2. This limiting method not only simplifies the assembly process, but also improves the stability of the overall structure.

[0045] After the motor 3 body is installed at the designated position, the motor housing 1 and the housing base 2 can be tightly connected by rotating them at a certain angle. This design ensures that the motor 3 will not fall off, and no additional fasteners or tools are required, which simplifies the assembly process and reduces the assembly cost.

[0046] The overall solution improves the overall structural reliability between the motor housing 1 and the housing base 2 through precise matching and stable connection. This design makes the equipment more stable and reliable during operation, reduces failures caused by structural looseness or deformation, and brings users a more convenient and efficient use experience.

[0047] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
