Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servo driver, and particularly relates to a servo driver shell. BACKGROUND

[0002] The servo driver is a kind of controller for controlling servo motor, and is widely applied to the industrial manufacturing field.

[0003] When the servo driver controls the rotation of the servo motor, the heat-emitting element will emit heat, so in the structural design of the servo driver, in addition to the aluminum radiator, the plastic shell is also provided with a heat dissipation vent. However, in some special application occasions, such as occasions with small load, the servo driver does not need to run for a long time at high power, and the heat emission is small, but these occasions often have high requirements for dustproof and waterproof. The existing servo driver structure has obvious deficiencies in dustproof and waterproof because the plastic shell is provided with a heat dissipation vent, although it is beneficial to heat dissipation. Dust and water vapor can easily enter the inside of the driver through the vent, causing damage to the internal components and affecting the normal operation and service life of the driver, especially in some extremely harsh industrial environments, such as textile, food processing, chemical industry and the like. For this, the existing solution is usually to replace the fully enclosed shell, but this solution requires the production manufacturer to additionally increase the shell mold, which increases the mold cost, and at the same time, the production, inventory and the like increase the product type by one time, which reduces the production efficiency; for the customers, different shell driver products need to be prepared for different protection requirements, which increases the use cost and the complexity of inventory management, and the operation of replacing the shell is relatively cumbersome and not convenient.

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] As shown in Figure 1 and Figure 2 As an implementation manner, the present application provides a servo driver shell, which comprises a shell body 1, a protective plate 2, a circuit board, a heat dissipation fan, etc. The shell body 1 is internally formed with a containing cavity. The circuit board, the heat dissipation fan, etc. are installed in the containing cavity. The shell body 1 wraps and protects the circuit board and the heat dissipation fan. Meanwhile, the servo driver is installed on a required installation device through the shell body 1. The protective plate 2 is used to block the opening part of the shell body 1, so as to reduce the risk of dust and water vapor entering the shell body 1.

[0023] It should be noted that the present application only improves the shell of the servo driver, and does not improve the structure of the circuit board, the structure of the heat dissipation fan, and the installation manner.

[0024] Specifically, the side wall of the shell body 1 is formed with a heat dissipation area 101. The heat dissipation area 101 is uniformly formed with heat dissipation grooves 102. The heat dissipation grooves 102 are communicated with the containing cavity, so as to exchange the air outside the shell body 1 with the air in the containing cavity, thereby reducing the temperature in the containing cavity and achieving heat dissipation of the components in the shell body 1.

[0025] The protective plate 2 is located outside the shell body 1, so as to facilitate the user to disassemble and assemble the protective plate 2. The protective plate 2 is installed on the heat dissipation area 101 and closes the heat dissipation grooves 102 through the protective plate 2.

[0026] When the servo driver is applied to a scene with small heat generation (small working power), the protective plate 2 is installed on the shell body 1, so as to reduce the risk of dust and water vapor entering the shell body 1 and improve the service life of the servo driver.

[0027] When the servo driver is applied to a scenario with large heat generation (large working power), the protective plate 2 is separated from the shell body 1, so as to improve the heat dissipation efficiency of the servo driver, and also improve the service life of the servo driver.

[0028] To more clearly illustrate the technical solutions of the present application, the up-down direction is defined as shown in Figure 1 The thickness direction of the shell body 1 is the up-down direction shown in Figure 1 The connecting line direction of the first wall 201 and the second wall 202 is the left-right direction shown in Figure 1

[0029] As an implementation manner, the shell body 1 is formed with two heat dissipation areas 101. By arranging the two heat dissipation areas 101, the external air can flow through the two heat dissipation areas 101 in sequence, so as to improve the air exchange efficiency in the containing cavity and improve the heat dissipation efficiency of the servo driver.

[0030] Specifically, the two heat dissipation areas 101 are located on two opposite side walls of the shell body 1, so as to improve the efficiency of the external air flowing through the shell body 1.

[0031] The protective plate 2 is installed on each of the two heat dissipation areas 101, so as to close the heat dissipation grooves 102 in the two heat dissipation areas 101 by the protective plate 2, reduce the risk of dust and water vapor entering the shell body 1, and improve the service life of the servo driver.

[0032] In the present implementation manner, the heat dissipation area 101 is located on the upper and lower side walls of the shell body 1.

[0033] It should be noted that the heat dissipation area 101 can be located on any side wall of the shell body 1, and the present application describes the heat dissipation area 101 located on the upper and lower side walls of the shell body 1.

[0034] As an implementation manner, the heat dissipation area 101 is also formed with a groove 103, the heat dissipation groove 102 is located in the groove 103, and the protective plate 2 is installed in the groove 103.

[0035] After the protective plate 2 is installed, the distance of the dust and water vapor moving from the outside of the protective plate 2 to the heat dissipation groove 102 is increased, so as to reduce the risk of dust and water vapor entering the shell body 1 and improve the service life of the servo driver.

[0036] It should be noted that the side wall of the protective plate 2 and the groove side wall of the groove 103 are in transition fit, which can improve the disassembly convenience of the protective plate 2 on the one hand, and improve the sealing performance of the protective plate 2 in closing the heat dissipation groove 102 on the other hand.

[0037] ​As an implementation, the thickness of the protection plate 2 is less than or equal to the depth of the groove 103 along the thickness direction of the shell body 1, that is, the outer side end surface of the protection plate 2 is located on the same plane as the outer side end surface of the shell body 1, or the outer side end surface of the protection plate 2 is located on the inner side of the outer side end surface of the shell body 1.

[0038] Through the above arrangement, the protection plate 2 is prevented from protruding from the shell body 1, and the increase in packaging and installation space caused by the installation of the protection plate 2 is eliminated, so as to improve the structural compactness of the servo driver.

[0039] As shown in Figure 2 As an implementation, the protection plate 2 includes a first wall 201 and a second wall 202 arranged opposite to each other, that is, the first wall 201 and the second wall 202 are respectively located on opposite sides of the protection plate 2.

[0040] The first wall 201 is formed with a first connecting portion 203, and the second wall 202 is formed with a second connecting portion 204. The first connecting portion 203 and the second connecting portion 204 are respectively connected with the shell body 1 to install the protection plate 2 in the heat dissipation area 101.

[0041] By arranging the first connecting portion 203 and the second connecting portion 204 on opposite sides of the protection plate 2, the connection stability of the protection plate 2 and the shell body 1 can be improved.

[0042] As shown in Figure 2 As an implementation, the first connecting portion 203 at least partially protrudes out of the first wall 201 along the connecting direction of the first wall 201 and the second wall 202. By inserting the first connecting portion 203 into the shell body 1 along the left-right direction, the first wall 201 is connected with the shell body 1.

[0043] As shown in Figure 1 The heat dissipation area 101 is formed with an insertion slot 105 extending along the connecting direction of the first wall 201 and the second wall 202, and the first connecting portion 203 is inserted into the insertion slot 105.

[0044] As an implementation, the second connecting portion 204 at least partially extends into the shell body 1 along the thickness direction of the shell body 1. By inserting the second connecting portion 204 into the shell body 1 along the up-down direction, the second wall 202 is connected with the shell body 1.

[0045] Further, the second connecting portion 204 has a certain deformation capability along the connecting direction of the first wall 201 and the second wall 202, so as to facilitate the abutment of the second connecting portion 204 with the inner wall of the accommodating cavity, thereby clamping at least part of the second connecting portion 204 in the shell body 1.

[0046] As shown in Figure 2As shown, as an implementation manner, the second connecting part 204 comprises a connecting segment 2042 and a lapping part 2041, the connecting segment 2042 extends along the thickness direction of the shell body 1 so as to facilitate the insertion of at least part of the second connecting part 204 into the shell body 1, and the lapping part 2041 is connected to the end of the connecting segment 2042 away from the second wall 202.

[0047] As shown, a clamping groove 104 is formed in the heat dissipation area 101, and the clamping groove 104 penetrates the shell body 1 along the thickness direction of the shell body 1, and the lapping part 2041 is inserted into the shell body 1 through the lapping part 2041, and the lapping part 2041 at least partially abuts against the inner wall of the shell body 1, so as to clamp the second connecting part 204 in the clamping groove 104. Figure 1 As an implementation manner, the protective plate 2 is provided with a deformation groove 205, which is located on both sides of the second connecting part 204. Through the arrangement of the deformation groove 205, the deformation of the second connecting part 204 is facilitated, and the service life of the protective plate 2 is improved.

[0048] As an implementation manner, a tool space 4 is formed between the second connecting part 204 and the inner wall of the clamping groove 104, that is, the end face of the connecting segment 2042 towards the inner wall of the clamping groove 104 and the inner wall of the clamping groove 104 have the tool space 4 therebetween, so as to facilitate the deformation of the second connecting part 204 by a tool such as a screwdriver, thereby facilitating the separation of the lapping part 2041 from the inner wall of the shell body 1, achieving the unlocking of the second connecting part 204 and the clamping groove 104, and thereby facilitating the dismounting of the protective plate 2 from the shell body 1.

[0049] As an implementation manner, the servo driver shell further comprises a sealing member 3, which is located between the heat dissipation area 101 and the protective plate 2.

[0050] As shown, as an implementation manner, the sealing member 3 is fixed on the end face of the protective plate 2 towards the shell body 1, thereby improving the installation convenience of the sealing member 3.
