Description

Technical Field

[0001] This utility model relates to the field of motor protection technology, specifically to a vibration-resistant and shock-resistant motor structure. Background Technology

[0002] Generally, an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction is called an electric motor. In circuits, an electric motor is represented by the letter M (D in the old standard). Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. A generator is represented by the letter G in circuits. Its main function is to convert mechanical energy into electrical energy. Electric motors can be classified according to the type of power source they use: DC motors and AC motors.

[0003] Motors often suffer from fatigue cracks in their end caps and mounting bases during transportation or use due to the lack of vibration and impact resistance. This significantly shortens the motor's lifespan and, in extreme cases, may lead to complete failure, causing equipment downtime or safety accidents, thus affecting normal use.

[0004] Chinese Utility Model Patent Publication No. CN218472897U discloses a protective structure for an electric motor. The specification of this protective structure states that the motor body is protected by a protective mechanism, preventing short circuits caused by rainwater entering the motor through the output end during use. This significantly improves the motor's safety. However, while the protective structure provides protection, the use of a wraparound mounting sleeve increases costs and affects the overall normal operation of the motor. Furthermore, the lack of a quick-installation mechanism for the protective structure makes installation cumbersome, resulting in poor practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a vibration-resistant and shock-resistant motor structure. It can effectively solve the problems in the prior art, which not only leads to high cost due to the wrap-around installation sleeve, but also affects the normal use of the overall motor. Furthermore, the lack of a protective structure in the quick installation structure makes the installation process cumbersome and results in poor practicality.

[0006] The technical solution adopted by this utility model is: a vibration-resistant and shock-resistant motor structure, including a motor body and a mounting base. An anti-slip pad is snapped onto the end of the mounting base away from the motor body. A positioning groove one is opened at the end of the mounting base away from the motor body. A positioning groove two is opened at the end of the anti-slip pad away from the motor body. A positioning screw is threadedly connected to the inner edge of the positioning groove one and the positioning groove two. A protective sleeve is sleeved on the end of the motor body away from the mounting base. An end cover assembly is fixedly installed on the end of the motor body away from the protective sleeve.

[0007] The end cap assembly includes an end cap body, a through groove is provided at the center of the end cap body, a reinforcing ring is fixedly installed along the inner edge of the end cap body, and an alignment groove is provided at the end of the end cap body near the motor body.

[0008] Preferably, a reinforcing post is fixedly installed at the end of the reinforcing ring away from the motor body and at the end of the reinforcing ring close to the motor body. Multiple reinforcing posts are provided, and the multiple reinforcing posts are distributed in a ring about the center line of the motor body.

[0009] Through the above technical solution, the design of the reinforcing ring can disperse the stress along the inner edge of the end cover body, prevent the end cover body from deforming under external force, and the ring-shaped reinforcing columns further transmit the force to the connection surface between the end cover body and the motor body, thereby improving the deformation resistance of the end cover assembly.

[0010] Preferably, one cross-section of the positioning groove is a long, narrow circular hole, and a locking nut is threaded onto one end of the positioning screw near the mounting base.

[0011] With the above technical solution, when the positioning screw passes through positioning groove one and positioning groove two, its elongated hole allows the mounting base to be finely adjusted along the groove direction to adapt to different installation scenarios. In addition, the locking nut, through pre-tightening force, eliminates the gap between the screw and the groove body, prevents loosening, and improves its stability.

[0012] Preferably, the mounting base has a limiting groove 1 and a limiting groove 2 at the end away from the motor body, and the limiting groove 1 and the limiting groove 2 are nested with the anti-slip pad.

[0013] Through the above technical solution, the design of limiting groove one and limiting groove two, whose contours are adapted to the edge of the anti-slip mat, can limit the anti-slip mat and prevent it from moving in the horizontal direction, thereby further improving the anti-slip performance.

[0014] Preferably, the anti-slip pad is a rubber pad, and the mounting base has a slot at one end near the motor body, the slot being in contact with the outer wall of the motor body.

[0015] Through the above technical solution, the anti-slip pad made of rubber material has a large friction and elastic deformation performance, which can buffer motor vibration and prevent the mounting base from slipping. It is also fixed to the motor body through the slot to prevent it from shaking in the mounting base.

[0016] Preferably, a protective sleeve is fixedly installed at one end of the anti-slip pad near the second positioning groove. The protective sleeve has a "C" shaped cross-section, and at least two protective sleeves are fixedly installed on the outer edge of one second positioning groove.

[0017] Through the above technical solution, the design of the protective sleeve ensures that the positioning screw contacts the protective sleeve when connected, thus preventing the anti-slip pad from aging due to long-term use and affecting the fixing effect.

[0018] Preferably, the motor body has a mounting groove at one end near the end cover assembly, and a second positioning bolt is threaded through the end of the end cover assembly away from the motor body. The second positioning bolt passes through the end cover body and is threadedly connected to the mounting groove. A first positioning bolt is threadedly connected to the outer edge of the end cover body.

[0019] Through the above technical solution, by designing the mounting groove and positioning bolt two, the end cover can be first fitted to the motor body through the alignment groove, and then the end cover can be connected to the motor body through the positioning bolt two, thus realizing the rapid installation of the end cover assembly.

[0020] Compared with the prior art, this utility model provides a vibration-resistant and shock-resistant motor structure, which has the following beneficial effects:

[0021] 1. This vibration-resistant and shock-resistant motor structure, through the design of the reinforcing ring, can disperse the stress along the edge of the end cover body, prevent the end cover body from being deformed by external forces, and the ring-shaped reinforcing columns further transmit the force to the connection surface between the end cover body and the motor body, improving the deformation resistance of the end cover assembly. With the protective sleeve, it can protect the motor body, avoid wrapping the entire motor and affecting normal use, and at the same time reduce the overall cost.

[0022] 2. This vibration-resistant and shock-resistant motor structure, through the design of the mounting groove and the second positioning bolt, can first fit with the motor body through the alignment groove, and then connect the end cover body and the motor body together through the second positioning bolt, thus realizing the quick installation of the end cover assembly. The anti-slip pad made of rubber material, due to its large friction and elastic deformation performance, can buffer the motor vibration and prevent the mounting seat from slipping, and is fixed to the motor body through the slot to prevent it from shaking in the mounting seat.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-8 As shown, the anti-vibration and anti-impact motor structure provided by this utility model includes a motor body 1 and a mounting base 2. An anti-slip pad 9 is snapped onto the end of the mounting base 2 away from the motor body 1. A positioning groove 3 is opened at the end of the mounting base 2 away from the motor body 1. A positioning groove 10 is opened at the end of the anti-slip pad 9 away from the motor body 1. A positioning screw 4 is threadedly connected to the inner edge of the positioning groove 3 and the positioning groove 10. A protective sleeve 12 is sleeved on the end of the motor body 1 away from the mounting base 2. An end cover assembly 13 is fixedly installed on the end of the motor body 1 away from the protective sleeve 12.

[0034] The end cap assembly 13 includes an end cap body 1301, a through groove 1302 is provided at the center of the end cap body 1301, a reinforcing ring 1303 is fixedly installed at the inner edge of the end cap body 1301, and an alignment groove 1305 is provided at the end of the end cap body 1301 near the motor body 1.

[0035] Specifically, a reinforcing ring 1303 is fixedly installed at the end away from the motor body 1, and a reinforcing post 1304 is fixedly installed at the end of the reinforcing ring 1303 close to the motor body 1. Multiple reinforcing posts 1304 are provided, and the multiple reinforcing posts 1304 are distributed in a ring about the center line of the motor body 1. The advantage is that, through the design of the reinforcing ring 1303, the stress on the inner edge of the end cover 1301 can be dispersed, preventing the end cover 1301 from deforming under external force. Furthermore, the ring-shaped reinforcing posts 1304 further transmit the force to the connection surface between the end cover 1301 and the motor body 1, improving the deformation resistance of the end cover assembly 13.

[0036] Specifically, the positioning groove 3 has a long, circular hole in its cross-section. The positioning screw 4 is threaded with a locking nut 5 at one end near the mounting base 2. The advantage is that when the positioning screw 4 passes through the positioning groove 3 and the positioning groove 10, its long hole allows the mounting base 2 to be finely adjusted along the groove direction to adapt to different installation scenarios. In addition, the locking nut 5, with its pre-tightening force, eliminates the gap between the screw and the groove, prevents loosening, and improves its stability.

[0037] Specifically, the mounting base 2 has a limiting groove 6 and a limiting groove 7 at the end away from the motor body 1. The limiting groove 6 and the limiting groove 7 are nested with the anti-slip pad 9. The advantage is that the design of the limiting groove 6 and the limiting groove 7 allows the outline of the limiting groove 6 and the limiting groove 7 to match the edge of the anti-slip pad 9, which can limit the movement of the anti-slip pad 9 and prevent it from moving in the horizontal direction, thus further improving its anti-slip performance.

[0038] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, the anti-slip pad 9 is a rubber pad, and the mounting base 2 has a slot 8 at one end near the motor body 1. The slot 8 fits against the outer wall of the motor body 1. The advantage is that the anti-slip pad 9, made of rubber, has a large friction and elastic deformation performance, which can buffer the motor vibration and prevent the mounting base 2 from slipping. In addition, it is fixed to the motor body 1 through the slot 8 to prevent it from shaking in the mounting base 2.

[0040] Specifically, a protective sleeve 11 is fixedly installed at one end of the anti-slip pad 9 near the second positioning groove 10. The protective sleeve 11 has a "C" shaped cross-section. At least two protective sleeves 11 are fixedly installed on the outer edge of one second positioning groove 10. The advantage is that, through the design of the protective sleeve 11, when connecting the positioning screw 4, the positioning screw 4 can be made to contact the protective sleeve 11, thereby avoiding the anti-slip pad 9 from aging easily after long-term use, which would affect normal fixation.

[0041] Specifically, the motor body 1 has a mounting groove 16 at one end near the end cover assembly 13, and a second positioning bolt 15 is threaded through the end of the end cover assembly 13 away from the motor body 1. The second positioning bolt 15 passes through the end cover body 1301 and is threadedly connected to the mounting groove 16. A first positioning bolt 14 is threadedly connected to the outer edge of the end cover body 1301. The advantage is that, through the design of the mounting groove 16 and the second positioning bolt 15, the end cover body 1301 can be first fitted with the motor body 1 through the alignment groove 1305, and then the end cover body 1301 and the motor body 1 can be connected together through the second positioning bolt 15, thus enabling the quick installation of the end cover assembly 13.

[0042] Working Principle: During use, the design of the reinforcing ring 1303 disperses the stress along the inner edge of the end cover 1301, preventing deformation of the end cover 1301 under external force. Furthermore, the annularly distributed reinforcing columns 1304 further transmit the force to the connection surface between the end cover 1301 and the motor body 1, enhancing the deformation resistance of the end cover assembly 13. When the positioning screw 4 passes through the positioning groove 10 and the positioning slot 2, its elongated hole allows for fine-tuning of the mounting base 2 along the groove direction, adapting to different installation scenarios. The locking nut 5, with its pre-tightening force, eliminates the gap between the screw and the groove, preventing loosening and improving stability. The design of the limiting grooves 16 and 27 allows their contours to match the edge of the anti-slip pad 9, thus limiting the anti-slip pad 9. The anti-slip pad 9, made of rubber, prevents horizontal movement and further improves its anti-slip properties. Due to its large friction and elastic deformation performance, it can buffer motor vibration and prevent the mounting base 2 from slipping. It is fixed to the motor body 1 through the slot 8 to prevent it from shaking in the mounting base 2. The design of the protective sleeve 11 allows the positioning screw 4 to contact the protective sleeve 11 when connected, thus preventing the anti-slip pad 9 from aging easily after long-term use, which would affect normal fixation. Through the design of the mounting groove 16 and the positioning bolt 15, the end cover 1301 can be attached to the motor body 1 through the alignment groove 1305, and then the end cover 1301 and the motor body 1 can be connected together through the positioning bolt 15, which can then realize the quick installation of the end cover assembly 13.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
