Description

Technical Field

[0001] This utility model relates to the field of DC motor technology, and in particular to a DC motor locking mechanism. Background Technology

[0002] In typical worm gear reducer motors of similar products, the front and rear covers of the motor can only be locked with screws. This greatly limits the specifications of the brushless stator, requiring the motor to have a stator structure that can pass through the screws in order to be used. Furthermore, the passing screws may affect the use of the motor and may lead to loosening and falling off in the long run, resulting in poor fastening effect. Therefore, there is an urgent need for a DC motor locking mechanism to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a DC motor locking mechanism to solve the technical problems of limited locking methods for the front and rear covers of existing DC motors, limited stator inner diameter specifications, and poor fastening effect.

[0004] This utility model discloses a DC motor locking mechanism, which is used to fix the motor housing and the gearbox housing. The gearbox housing is located above the motor housing. The motor housing has multiple mounting slots on its side wall. A baffle is inserted horizontally into each mounting slot. The baffle has a first screw hole. The motor housing has a front cover and a tail cover at its front and rear ends. The front cover is integrated with the gearbox housing. The front cover and tail cover have second screw holes corresponding to the positions of the first screw holes. Screws pass through the second screw holes and the first screw holes. The inner walls of the front cover and tail cover have grooves for placing the baffles.

[0005] Preferably, the baffle has a square, circular, or polygonal structure.

[0006] Preferably, at least four mounting slots are provided, with two mounting slots on the upper part of the motor housing and two mounting slots on the lower part.

[0007] Preferably, the outer side of the groove is provided with a notch.

[0008] Preferably, the baffle is fixedly connected to the screw to form a T-shaped structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This DC motor locking mechanism is used to fix the motor housing and the gearbox housing. The motor housing has a front cover and a tail cover at its front and rear ends, respectively. The front cover and the gearbox housing are integrally molded and fixed with screws. The side wall of the motor housing has multiple mounting slots, and baffles are installed in the mounting slots. The baffles have a first screw hole in the middle, and the front cover and tail cover have a second screw hole. During installation, screws are inserted from the second screw hole into the first screw hole to fix them together, ensuring that the various housing structures are locked together and the structure is more robust. By setting grooves on the inner walls of the front cover and tail cover that are adapted to the baffles, the position of the baffles is limited, ensuring that the baffles will not shift during installation. The locking structure of the baffles and screws creates tension at both ends of the motor housing, ensuring a better fastening effect. At the same time, it does not require limiting the inner diameter of the motor stator, making it more practical. Attached Figure Description

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] like Figure 1-3As shown, this utility model discloses a DC motor locking mechanism. The locking mechanism is used to fix the motor housing 1 and the gearbox housing 2. The gearbox housing 2 is located above the motor housing 1. The side wall of the motor housing 1 is provided with a plurality of mounting slots 11. A baffle 3 is inserted horizontally into the mounting slots 11. The baffle 3 is provided with a first screw hole 31. The front and rear ends of the motor housing 1 are provided with a front cover 4 and a tail cover 5. The front cover 4 is connected to the gearbox housing 2 as a whole. The front cover 4 and the tail cover 5 are provided with a second screw hole 41 corresponding to the position of the first screw hole 31. Screws 6 pass through the second screw hole 41 and the first screw hole 31. The inner wall of the front cover 4 and the tail cover 5 is provided with a groove 42 for placing the baffle 3.

[0018] This utility model discloses a DC motor locking mechanism for fixing a motor housing 1 and a gearbox housing 2. The motor housing 1 has a front cover 4 and a rear cover 5 at its front and rear ends, respectively. The front cover 4 and the gearbox housing 2 are integrally molded and fixed by screws 6. Multiple mounting slots 11 are provided on the side wall of the motor housing 1, and baffles 3 are disposed within these slots. A first screw hole 31 is provided in the middle of the baffle 3, and second screw holes 41 are provided on the front cover 4 and the rear cover 5. During installation, the screws 6 are inserted through the second screw holes. The hole 41 is inserted into the first screw hole 31 for fixing, which can fix the gearbox housing 2, front cover 4, motor housing 1 and tail cover 5 together, ensuring that the various housing structures are locked together and the structure is more robust; by setting the groove 42 on the inner wall of the front cover 4 and the tail cover 5 to match the baffle 3, the position of the baffle 3 is limited, ensuring that the baffle 3 will not shift when it is installed and inserted; the locking structure of the baffle and screw creates tension at both ends of the motor housing 1, ensuring a better fastening effect. At the same time, it is not necessary to limit the inner diameter of the motor stator, making it more practical.

[0019] When it is necessary to fix the various housing structures, first assemble the gearbox housing 2, front cover 4, motor housing 1 and tail cover 5 together in sequence, then insert the baffle 3 into the side wall of the motor housing 1, and finally fix it with screws 6. The operation is simple and convenient.

[0020] In a preferred embodiment, refer to Figure 1-3 The baffle 3 of the DC motor locking mechanism has a square, circular, or polygonal structure. At least four mounting slots 11 are provided; two mounting slots are located on the upper part of the motor housing 1, and two on the lower part. A notch 421 is provided on the outer side of the groove 42. The baffle 3 is fixedly connected to the screw 6, forming a T-shaped structure.

[0021] The shape of the baffle 3 is preferably square, but it can also be round, triangular, or polygonal, and is not limited here. The number of mounting slots 11 is set according to the number of baffles 3, usually four, with two at the top and two at the bottom, so that both sides of the housing can be fastened. By setting a notch 421 on the outside of the groove 42, the width of the notch 421 is greater than the width or outer diameter of the baffle 3, ensuring that the baffle 3 can be inserted into the groove 42. The shape of the groove 42 is the same as or similar to the shape of the baffle 3, ensuring that the baffle 3 can be placed inside it without displacement. A T-shaped structure is formed between the baffle 3 and the screw 6. The two ends of the T-shaped structure are hooked on the mounting slots 11 of the housing. When the screw 6 is tightened, a tension is formed between the motor housing 1 and the tail cover 5 and the front cover 4, so that the motor housing 1 and the tail cover 5 and the front cover 4 are fastened, achieving the effect of fastening.

[0022] The locking mechanism also has the following characteristics:

[0023] 1. Unlike traditional locking mechanisms where the screw passes through the entire machine, this design offers more flexible and convenient installation;

[0024] 2. This locking mechanism is compatible with both existing brushless and brushed motors, and has a wide range of applications;

[0025] 3. This locking mechanism no longer limits the specifications of the stator inner diameter of the brushless motor, making it more practical.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
