Description

Technical Field

[0001] This utility model relates to the field of micro motors, and in particular to a micro motor fixing clip. Background Technology

[0002] A micro motor is a small electric motor that is typically used in applications requiring low power and a compact design, such as electric toothbrushes, shavers, and medical devices. During the installation of a micro motor, certain structures are needed to help secure it.

[0003] A search revealed Chinese Patent Publication No. CN219999146U, which discloses a micro motor clamping clip, relating to the field of clamping frame technology. The clip includes a main body with two fixing mechanisms positioned between it, facing each other. Multiple lifting mechanisms are located on both sides of the main body, with the two fixing mechanisms positioned between them. Each fixing mechanism includes two rubber parts, multiple connecting plates, and multiple return springs. One end of each return spring is fixedly connected to the bottom of the connecting plates, and the opposite side of each rubber part is fixedly connected to the other end of each return spring. The user places the micro motor on the bottom rubber part and controls the lifting cylinder to retract downwards, causing the top rubber part to contact the micro motor until it is clamped. The rubber parts are flexible and have low hardness, avoiding the risk of damage to the micro motor during clamping.

[0004] Although the above-mentioned device can protect the motor and prevent damage to the micro motor during clamping by setting rubber parts and springs, the springs are prone to vibration when subjected to external forces. This makes the clamping and fixing of the micro motor by the structure not stable enough and not practical. Therefore, a micro motor fixing clip is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a micro motor fixing clip, which aims to improve the problem that in the prior art, the spring is prone to vibration when subjected to external force, which leads to the structure being unstable and impractical in clamping and fixing the micro motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a micro motor fixing clamp, comprising two clamping plates, with multiple bolts provided between the two clamping plates, fixing pads provided on the inner walls of both clamping plates, two upright plates fixedly connected to the bottom surface of the lower clamping plate, and a mounting plate fixedly connected to the bottom of the two upright plates; multiple buffer strips fixedly connected to the middle of the fixing pads, and a buffer cavity opened in the middle of the buffer strips.

[0007] As a further description of the above technical solution:

[0008] Limiting strips are fixedly connected to both the front and rear parts of the fixing pad near the clamping plate.

[0009] As a further description of the above technical solution:

[0010] The fixing pad has multiple auxiliary openings in the middle, and the auxiliary openings are located between two adjacent buffer strips.

[0011] As a further description of the above technical solution:

[0012] The buffer strip has a retaining strip on the side near the clamping plate.

[0013] As a further description of the above technical solution:

[0014] The card strip includes a rectangular strip, which is fixedly connected to a buffer strip and a fixed pad. A hollow strip is fixedly connected to one end of the rectangular strip near the clamping plate.

[0015] As a further description of the above technical solution:

[0016] The clamping plate has multiple heat dissipation vents in the middle.

[0017] As a further description of the above technical solution:

[0018] The clamping plate has limit grooves on both the front and rear sides of its inner wall, and the limit strip is movably connected to the limit groove. The clamping plate has multiple slots in the middle of its inner wall, and the slot strip is movably connected to the slot.

[0019] As a further description of the above technical solution:

[0020] The two clamping plates are fixedly connected to the left and right sides of each other on the side that are close to each other, and the bolts are threadedly connected to the fixed plates.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up the cooperation between components such as fixing pads, buffer strips, and buffer cavities, the fixing clamp can protect the motor when clamping and fixing the micro motor. Compared with the protective structure of springs and rubber parts, this structure is less prone to vibration due to external forces, and is more stable and more practical.

[0023] 2. In this utility model, by setting heat dissipation vents on the clamping plate and auxiliary vents on the fixing pad, the heat dissipation of the motor can be better coordinated. At the same time, by setting limit grooves, slots and limit strips, and other components to cooperate with each other, the disassembly and replacement of the fixing pad is more convenient, quick and practical.

[0030] 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.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a micro motor fixing clamp, including two clamping plates 1 for fixing a micro motor. The two clamping plates 1 can form a fixing clamp. A plurality of bolts 5 are provided between the two clamping plates 1 for fixing the two clamping plates 1 together to fix the micro motor. The inner walls of the two clamping plates 1 are provided with fixing pads 2, which can be made of rubber. The bottom surface of the lower clamping plate 1 is fixedly connected to two upright plates 3 for fixing the clamping plate 1 to the mounting plate 4. The bottom of the two upright plates 3 is fixedly connected to the mounting plate 4 for mounting the fixing clamp.

[0032] like Figure 2 - Figure 4 As shown, the fixing pad 2 has limit strips 22 fixedly connected to both the front and rear sides of its side near the clamping plate 1. These limit strips are used to connect the fixing pad 2 to the clamping plate 1. Multiple buffer strips 23 are fixedly connected to the middle of the fixing pad 2 for cushioning. A buffer cavity 231 is formed in the middle of the buffer strip 23, allowing for slight deformation of the buffer strip 23 to protect the micro motor. Multiple auxiliary ports 21 are formed in the middle of the fixing pad 2, corresponding to the positions of the heat dissipation ports 11 on the clamping plate 1. The auxiliary ports 21 are located on two adjacent... Between adjacent buffer strips 23, a retaining strip 24 is provided on the side of the buffer strip 23 near the clamping plate 1. It is used to cooperate with the installation of the fixing pad 2. The retaining strip 24 includes a rectangular strip 241, which is used to connect various components. The rectangular strip 241 is fixedly connected to the buffer strip 23 and the fixing pad 2. The rectangular strip 241 passes through and is fixedly connected to the fixing pad 2. A hollow strip 242 is fixedly connected to the end of the rectangular strip 241 near the clamping plate 1. It can produce a certain degree of deformation, so that the retaining strip 24 and the slot 14 can be better disassembled and assembled. The limiting strip 22, the retaining strip 24, and the buffer strip 23 are all made of rubber.

[0033] Furthermore, the clamping plate 1 has multiple heat dissipation vents 11 in the middle, which are used to facilitate the heat dissipation of the micro motor. The clamping plate 1 has limit grooves 12 on both the front and rear sides of its inner wall, which are used to connect with the limit strip 22. The shape of the limit grooves 12 is adapted to the limit strip 22. The limit strip 22 is movably connected to the limit grooves 12. The clamping plate 1 has multiple slots 14 in the middle of its inner wall, which are used to connect with the slot strip 24. The slot strip 24 is movably connected to the slots 14. Fixing plates 13 are fixedly connected to the left and right sides of the two clamping plates 1 that are close to each other, which are used to facilitate the installation between the two clamping plates 1. Bolts 5 are threadedly connected to the fixing plates 13.

[0034] Working principle: When in use, first align the two clamps 1 and put them on the outside of the micro motor, so that the fixing pads 2 inside the micro motor are pressed against and fixed. When the fixing pads 2 are pressed against the micro motor, the buffer strip 23 has a buffer cavity 231, which will deform to a certain extent, thereby protecting the motor. Then, fix the fixing plates 13 on the two clamps 1 together with multiple bolts 5, so that the two clamps 1 can fix the micro motor. During use, the fixing clamps can be used to help the motor dissipate heat through the auxiliary port 21 and the heat dissipation port 11.

[0035] When the fixing pad 2 needs to be replaced, pull the fixing pad 2 to disengage the limiting strip 22 from the limiting groove 12 and the locking strip 24 from the locking groove 14. When the locking strip 24 disengages from the locking groove 14, the hollow strip 242 will deform to a certain extent, thus allowing the hollow strip 242 to detach from the clamping plate 1. Then, align the limiting strip 22 on the new fixing pad 2 with the limiting groove 12 and the locking strip 24 with the locking groove 14. Then press the fixing pad 2 to insert the limiting strip 22 into the limiting groove 12 and the locking strip 24 into the locking groove 14. During the process of the locking strip 24 being inserted into the locking groove 14, the hollow strip 242 will deform to a certain extent due to compression. When the locking strip 24 is fully inserted into the locking groove 14, the hollow strip 242 will return to its original shape and be locked in the locking groove 14, thus completing the fixing between the fixing pad 2 and the clamping plate 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
