Description

Technical Field

[0001] The utility model belongs to the technical field of motor heat dissipation, and relates to a heat dissipation motor shell, in particular to a wear-resistant motor shell with heat dissipation effect. Background Art

[0002] The main function of the motor is to convert electrical energy into mechanical energy. During use, the motor will generate a large amount of heat, so a large amount of heat needs to be transferred out; the motor housing in the prior art is mostly a closed structure, which is not conducive to heat dissipation. If the motor works under overload for a long time, the reliability is often very poor, which will affect the working efficiency and service life of the motor.

[0003] After searching, it is found that a Chinese patent document discloses a motor housing with high efficiency heat dissipation [Application number: 202221204505.6; Publication number: CN 218162032 U]. A motor housing with high efficiency heat dissipation includes: a motor housing body to accommodate the motor; a front end cover, which is detachably connected to the front end of the motor housing body to close one end of the motor housing body; a docking piece, which is detachably connected to the front end cover, one end of the docking piece is connected to the motor output shaft contained in the motor housing body, and the other end of the docking piece is assembled and connected to the driven part; a rear end cover, which is detachably connected to the rear end of the motor housing body to close the other end of the motor housing body; a plurality of heat dissipation through holes are arranged on the rear end cover, and a dust filter is connected in each heat dissipation through hole. A plurality of heat dissipation through holes are arranged on the rear end cover, which is convenient for installing the internal motor of the utility model for rapid heat dissipation. A dust filter is connected in each heat dissipation through hole, which is conducive to reducing dust entering the motor housing body during the heat dissipation process.

[0004] This patent simply opens heat dissipation holes to increase the airflow and exchange efficiency within the motor housing, which is beneficial for removing the heat generated by the motor itself and ensuring the normal operation of the motor. However, it lacks the ability to actively exchange airflow, resulting in a low heat dissipation effect. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a wear-resistant motor housing with heat dissipation effect. The technical problem to be solved by the utility model is: how to actively realize air circulation in the motor housing to improve the heat dissipation effect.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A wear-resistant motor housing with heat dissipation effect comprises a housing and a motor body arranged in the housing, the housing comprises an upper housing and a lower housing, the upper housing and the lower housing are connected by a quick fixing assembly, an air inlet is provided on the housing, a placement cavity for accommodating the motor body is provided in the housing, the air inlet is connected to the placement cavity, a ventilation and heat dissipation assembly is arranged in the housing, and the ventilation and heat dissipation assembly is connected to the placement cavity.

[0008] The working principle of the utility model is: the shell can be quickly assembled through a quick fixing component, and a ventilation and heat dissipation component is set in the shell to absorb external air through the air inlet hole, and the ventilation and heat dissipation component is used to allow the external air to contact and carry the temperature of the motor body to flow to the outside, so as to cool the motor body and extend the service life of the motor body.

[0009] The inner wall of the placement cavity is fixedly connected with a heat dissipation copper plate.

[0010] By adopting the above structure, the heat dissipation copper plate fixed in the placement cavity can better absorb the temperature generated by the motor body, and cooperate with the ventilation and heat dissipation components to accelerate the heat dissipation and improve the heat dissipation efficiency.

[0011] The ventilation and heat dissipation component includes a heat dissipation cavity opened in the shell, a heat dissipation fan fixedly connected in the heat dissipation cavity, an air outlet passing through the shell is opened on the heat dissipation cavity, dustproof nets are fixed in the air outlet and the air inlet, a heat dissipation hole is opened between the heat dissipation cavity and the placement cavity, a plurality of heat dissipation fins are fixed on the heat dissipation copper plate, and the other end of the heat dissipation fin extends into the heat dissipation hole.

[0012] With the above structure, the heat dissipation fan can be started to draw air from the placement cavity, and further draw air from the air inlet into the placement cavity. Finally, the air is discharged through the heat dissipation fan to complete the air circulation, and the motor body is cooled by air cooling. The heat dissipation copper plate and the heat dissipation holes are connected by heat dissipation fins, so that the heat can be directly transferred to the heat dissipation holes. In this way, the heat dissipation can be performed faster during normal heat dissipation work.

[0013] The quick fixing assembly includes a bidirectional lead screw rotatably connected in the upper shell, and a pair of bent plates slidably connected in the upper shell. The two bent plates are respectively threadedly connected to the corresponding ends of the bidirectional lead screw, and both ends of the bent plates are fixedly connected with snap blocks. The lower shell is provided with a snap groove that snaps with the snap block.

[0014] By adopting the above structure, the two-way screw can be rotated to drive the bending plate to move in relative or opposite directions, and further drive the snap block to complete the snap connection with the snap groove, thereby quickly completing the assembly of the shell and improving the overall use efficiency.

[0015] A micro motor is fixed in the upper shell, and a transmission gear 1 is coaxially fixedly connected to the output end of the micro motor. A transmission gear 2 is coaxially fixed on the bidirectional lead screw, and the transmission gear 1 is meshed with the transmission gear 2.

[0016] With the above structure, the micro motor can drive the transmission gear 1 to rotate, and the transmission gear 1 repeatedly drives the transmission gear 2 to rotate by meshing with the transmission gear 2. After the transmission gear 2 rotates, it will drive the bidirectional lead screw to operate, and cooperate with the subsequent structure to complete the shell assembly work.

[0017] Compared with the prior art, the wear-resistant motor housing with heat dissipation effect has the following advantages:

[0018] 1. The micro motor drives the transmission gear 1 to rotate, and the transmission gear 1 repeatedly meshes with the transmission gear 2 to drive the transmission gear 2 to rotate. After the transmission gear 2 rotates, it will drive the bidirectional lead screw to operate. Through the rotation of the bidirectional lead screw, the bending plate is driven to move in relative or opposite directions, and further drives the buckle block to complete the buckle connection with the buckle groove, thereby quickly completing the assembly of the shell and improving the overall use efficiency.

[0019] 2. By starting the cooling fan, the cooling fan draws air from the placement cavity, and further draws air from the air inlet into the placement cavity, and finally discharges the air through the cooling fan to complete the air circulation, and cools the motor body through air cooling, thereby extending the service life of the motor body.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1-Figure 4 As shown, a wear-resistant motor housing with heat dissipation effect includes a housing 1 and a motor body 2 arranged in the housing 1, the housing 1 includes an upper housing 3 and a lower housing 4, the upper housing 3 and the lower housing 4 are connected by a quick fixing component 5, an air inlet 6 is opened on the housing 1, a placement cavity 7 for accommodating the motor body 2 is opened in the housing 1, the air inlet 6 is connected to the placement cavity 7, a ventilation and heat dissipation component 9 is arranged in the housing 1, and the ventilation and heat dissipation component 9 is connected to the placement cavity 7.

[0027] The shell 1 can be quickly assembled through the quick fixing component 5, and a ventilation and heat dissipation component 9 is set in the shell 1 to absorb outside air through the air inlet 6. The ventilation and heat dissipation component 9 allows the outside air to contact and carry the temperature of the motor body 2 to the outside, thereby cooling the motor body 2 and extending the service life of the motor body 2.

[0028] A heat dissipation copper plate 10 is fixedly connected to the inner wall of the placement cavity 7 .

[0029] With the above structure, the heat dissipation copper plate 10 fixed in the placement cavity 7 can better absorb the temperature generated by the motor body 2, and cooperate with the ventilation and heat dissipation component 9 to accelerate the heat dissipation and improve the heat dissipation efficiency.

[0030] The ventilation and heat dissipation component 9 includes a heat dissipation cavity 11 opened in the shell 1, a heat dissipation fan 12 fixedly connected in the heat dissipation cavity 11, an air outlet 13 passing through the shell 1 is opened on the heat dissipation cavity 11, and dustproof nets 14 are fixed in the air outlet 13 and the air inlet 6. A heat dissipation hole 15 is opened between the heat dissipation cavity 11 and the placement cavity 7. A plurality of heat dissipation fins 22 are fixed on the heat dissipation copper plate 10, and the other end of the heat dissipation fin 22 extends into the heat dissipation hole 15.

[0031] By adopting the above structure, the heat dissipation fan 12 can be started to draw air from the placement cavity 7, and further draw air from the air inlet 6 into the placement cavity 7. Finally, the air is discharged through the heat dissipation fan 12 to complete the air circulation, and the motor body 2 is cooled by air cooling. The heat dissipation copper plate 10 and the heat dissipation hole 15 are connected by the heat dissipation fins 22, so that the heat is directly transferred to the heat dissipation hole 15. In this way, the heat dissipation can be performed faster during normal heat dissipation work.

[0032] The quick fixing assembly 5 includes a bidirectional lead screw 16 rotatably connected in the upper shell 3 and a pair of bent plates 17 slidably connected in the upper shell 3. The two bent plates 17 are respectively threadedly connected to the corresponding ends of the bidirectional lead screw 16. Both ends of the bent plates 17 are fixedly connected with snap blocks 18. The lower shell 4 is provided with a snap groove 21 that snaps with the snap block 18.

[0033] With the above structure, the rotation of the bidirectional lead screw 16 can drive the bending plate 17 to move in relative or opposite directions, and further drive the snap block 18 to complete the snap connection with the snap groove, thereby quickly completing the assembly of the shell 1 and improving the overall use efficiency.

[0034] A micro motor 20 is fixed in the upper housing 3 , and a transmission gear 1 8 is coaxially fixedly connected to the output end of the micro motor 20 . A transmission gear 2 19 is coaxially fixed on the bidirectional lead screw 16 , and the transmission gear 1 8 is meshed with the transmission gear 2 19 .

[0035] With the above structure, the micro motor 20 can drive the transmission gear 1 8 to rotate, and the transmission gear 1 8 can then drive the transmission gear 2 19 to rotate by meshing with the transmission gear 2 19. After the transmission gear 2 19 rotates, it will drive the bidirectional lead screw 16 to operate, and cooperate with the subsequent structure to complete the assembly of the shell 1.

[0036] The working principle of the utility model is as follows: first, the motor body 2 is placed between the upper shell 3 and the lower shell 4, and then the micro motor 20 is started to drive the transmission gear 1 8 to rotate. The transmission gear 1 8 is then meshed with the transmission gear 2 19 to drive the transmission gear 2 19 to rotate. After the transmission gear 2 19 rotates, it will drive the bidirectional lead screw 16 to operate. Through the rotation of the bidirectional lead screw 16, the bent plate 17 is driven to move relative or oppositely, and the buckle block 18 is further driven to complete the buckle connection with the buckle groove 21, so as to quickly complete the assembly of the shell 1. The motor body 2 after the shell is assembled can be used normally. The motor body 2 is prone to generate heat during use. When it reaches a certain level, the heat dissipation fan 12 is started. The heat dissipation fan 12 extracts air in the placement cavity 7, and further completes the extraction of air from the air inlet 6 into the placement cavity 7 to allow the outside air to contact and envelop the temperature of the motor body 2. Finally, the air is discharged through the heat dissipation fan 12 to complete the air circulation, and the motor body 2 is cooled by air cooling.

[0037] In summary, the shell 1 is quickly assembled through the quick fixing component 5, and a ventilation and heat dissipation component 9 is set in the shell 1 to absorb external air through the air inlet 6. The ventilation and heat dissipation component 9 allows the external air to contact and carry the temperature of the motor body 2 to the outside, thereby cooling the motor body 2 and extending the service life of the motor body 2.
