Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a motor housing structure. Background Art

[0002] The traditional motor housing mounting structure is to have fixing holes corresponding to the upper and lower ends of the housing, and to pass fixing screws through the fixing holes for fixing, mounting and locking. This type of mounting structure is easy to maintain, but the use of fixing screws is complicated. The screws need to be inserted into the fixing holes one by one, and then tightened one by one with an electric wrench. The material and production costs are high, and the bolts are easy to loosen due to long-term vibration, causing the motor to get stuck, which brings great trouble to the use of the motor.

[0003] In order to overcome the above defects, a motor housing installation structure that is installed and fixed by riveting has been produced. At present, the motor housing installed by riveting in the market has the following defects: the protruding clamping fixing parts at both ends of the shell body will affect the installation and use of the product due to their protruding structure. In addition, the existing motor housing installation structure will have a certain offset during the use of the drive rod, thereby affecting the work and service life of the product.

[0004] Therefore, it is urgent to provide a motor housing structure to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of the utility model is to provide a motor housing structure, which has the characteristics of reasonable structural arrangement and effectively improved service life and use accuracy.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A motor housing structure, comprising: a housing body, an upper cover and a lower cover respectively mounted at openings at both ends of the housing body, a plurality of slot positioning structures A capable of determining the same center of a circle are formed at the openings at both ends of the housing body, and a snap-fit ​​positioning structure B / C for snap-fitting and positioning with the slot positioning structure A is formed concavely on the upper cover / lower cover;

[0008] Both ends of the clamping and positioning structure B / C are formed with oblique buckles;

[0009] Each of the slot positioning structures A is formed with a clearance groove from the upper end surface downward to form riveted columns located on both sides of the slot positioning structure A;

[0010] After riveting, each of the slot positioning structures A is flush with the upper surface of the outer ring of the upper cover / lower cover, and the riveted column is in full contact with the inclined surface of the oblique buckle.

[0011] Preferably, during riveting, each of the riveting posts is riveted toward the corresponding oblique buckle to form an oblique groove for use with the oblique buckle.

[0012] Preferably, each of the snap-fit ​​positioning structures B / C is recessed in the upper cover / lower cover in a U-shaped manner, and the two riveted columns of each of the slot positioning structures A respectively abut against two inner arms of the opening of the snap-fit ​​positioning structure B / C.

[0013] Preferably, a groove one is formed on the inner side wall of each of the slot positioning structures A, and a protruding positioning portion one which is matched with the groove one for positioning is convexly provided on each of the snap-fit ​​positioning structures B / C.

[0014] Preferably, each of the oblique buckles is a trapezoidal structure formed by tilting the upper corner of the protruding portion on the side of the snap-fit ​​positioning structure B / C downward and partially avoiding the air.

[0015] Preferably, when not riveted, the two riveted columns are parallel and partially protrude from the outer annular surface of the upper cover / lower cover.

[0016] Preferably, after riveting, the two riveted posts corresponding to each of the slot positioning structures A are designed to be in an inverted "eight" shape.

[0017] Preferably, there are four card slot positioning structures A.

[0018] Compared with the prior art, the utility model has a motor housing structure in which the oblique buckle is formed on each of the upper cover / lower cover, and the air avoidance grooves are formed at both ends of the shell body to form riveted columns located on both sides of the slot fixing structure A. After riveting, each of the riveted columns is in full contact with the inclined surface of each of the oblique buckles, so that after the product is riveted, when the upper cover of the product is subjected to force, the pressure is vertically toward the lower cover, thereby overcoming the problem in the prior art that the upper cover under force is displaced, affecting the rotation and displacement of the drive shaft and thus affecting the use effect. In addition, the structural setting of the oblique buckle and the riveted column is such that when riveting, each riveted column is pressed like the corresponding inclined surface of each oblique buckle, thereby avoiding the problem in the prior art that the pressure of the upper cover or the lower cover during riveting causes the riveted part of the shell body to punch out a recessed portion, thereby overcoming the problem of product precision defects caused by the product structure design in the prior art. The present design has the characteristics of reasonable structural setting and effectively improving service life and use precision. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figure 1 and Figure 2 , a motor housing structure of this embodiment includes: a housing main body 1, an upper cover 2 and a lower cover 3 respectively riveted to both ends of the housing main body 1 where it is open.

[0031] Specifically, a plurality of slot positioning structures A11 capable of determining the same center of a circle are formed at both ports of the housing main body 1. This design effectively reduces production costs and improves product accuracy. Each slot positioning structure A11 is formed with a clearance groove from the upper end surface downward to form riveting posts 12 located on both sides of the slot positioning structure A11. On the upper cover 2 / lower cover 3, a clamping and positioning structure B21 / C that is clamped and positioned with the slot positioning structure A11 is recessed. Each clamping and positioning structure B21 / C is recessed in the shape of a U on the upper cover 2 / lower cover 3. The two riveting posts 12 of each slot positioning structure A11 respectively abut against the two inner side arms at the opening of the clamping and positioning structure B21 / C. More specifically, inclined buckles a are formed at both ends of the clamping and positioning structure B21 / C. During riveting, each riveting post 12 is riveted towards the corresponding inclined buckle a to form an inclined groove b that cooperates with the inclined buckle a. Specifically, the two unriveted riveting posts 12 are parallel and partially protrude from the outer ring surface of the upper cover 2 / lower cover 3. During riveting, each riveting post 12 is correspondingly riveted towards the inclined surface of the corresponding inclined buckle a so that one surface of the riveting post 12 is in full contact with the inclined surface of the inclined buckle a. This structural setting improves the simplicity of riveting while overcoming the defect in the prior art that a recessed part is punched out of the riveting part during the riveting process, thereby affecting the product quality. In addition, the riveting post 12 is riveted to form the inclined groove b to match the inclined buckle a, avoiding the influence of the riveting force on the product quality defects and improving the stability of the product.

[0032] In a preferred embodiment, a groove one is formed on the inner side wall of each slot positioning structure A11, and a protruding positioning part c that is paired and positioned with the groove one is protruded on each clamping and positioning structure B21 / C. The structural setting of the groove one and the protruding positioning part c facilitates the alignment of the upper cover 2 / lower cover 3 with the housing main body 1 and improves the convenience of product assembly and production. Specifically, designing the groove one and the protruding positioning part c helps with the center positioning of the product, helps reduce production costs while providing the accuracy of the product.

[0033] In a preferred embodiment, the slot positioning structure A11 is designed to be 4, and this structural design effectively improves the accuracy of the product and effectively reduces production costs.

[0034] In summary, the structural design of the riveted column 12 and the bevel buckle a of this product makes it easier to rivet. In addition, after riveting, the two ends of the shell body 1 are flush with the outer annular surfaces of the upper cover 2 and the lower cover 3, respectively, which overcomes the influence of the protrusion on the assembly and use of the product in the prior art, and the surface contact structure increases the force-bearing area of ​​the product and improves the force-bearing capacity of the product. Furthermore, in this structural design, the force direction of the upper cover 2 is vertically toward the lower cover 3, which overcomes the force offset in the prior art, affects the rotation direction of the drive shaft, and further affects the use accuracy of the product. The utility model has the characteristics of reasonable structural setting and effectively improves the service life and use accuracy.
