[0060] Reference Figure 1 and Figure 5 The control box mounting structure 100 provided in this application embodiment includes: a box body 10, a base 20, a connecting unit 30, and a mounting base 60.

[0061] The base 20 is fixed to the inside of the box body 10. The connecting unit 30 comprises at least one set of clamping assembly 50, the clamping assembly 50 comprises a support part 51, an operating arm 52 and a clamping arm 53 connected to the support part 51, the support part 51 is clamped between the wall part inside the box body 10 and the base 20, and the end of the clamping arm 53 is provided with a first clamping part 531. The mounting seat 60 is used for connecting with the box frame 40, and the mounting seat 60 comprises a second clamping part 62 for clamping with the first clamping part 531.

[0062] The box body 10 is provided with an operating hole 11 corresponding to the position of the operating arm 52, and the clamping assembly 50 is configured to move the clamping arm 53 when the operating arm 52 moves, so that the first clamping part 531 and the second clamping part 62 are disengaged.

[0063] The base 20 is connected to the wall part inside the box body 10, the support part 51 of the clamping assembly 50 is clamped between the wall part inside the box body 10 and the base 20, and the mounting seat 60 is connected with the box frame 40, so that when the first clamping part 531 connected to the support part 51 and the second clamping part 62 of the mounting seat 60 are clamped with each other, the box body 10 and the box frame 40 can be relatively fixed. When installing the control box, only the first clamping part 531 and the second clamping part 62 are clamped by operating the box body 10 to approach the box frame 40, and the quick connection of the two can be completed.

[0064] On the other hand, the box body 10 is provided with an operating hole 11 corresponding to the position of the operating arm 52, and the clamping assembly 50 is configured to move the clamping arm 53 when the operating arm 52 moves, so that the first clamping part 531 and the second clamping part 62 are disengaged. When disassembling the box body 10, only the first clamping part 531 and the second clamping part 62 are disengaged by operating the operating arm 52 through the operating hole 11 provided on the box body 10, so that the disassembly process is relatively simple. Since the installation and disassembly processes of the box body 10 and the box frame 40 are relatively simple, the work efficiency can be improved, and the quick installation and disassembly of the control box can be realized.

[0065] The box body 10 is the box body 10 of the control box (not shown), and the box body 10 can generally accommodate control circuit boards, cables and other components. In addition, the connection between the mounting seat 60 and the box frame 40 can be achieved by fasteners such as screws 41.

[0066] In some embodiments, in combination with Figure 5 and Figure 8The first snap-fit ​​portion 531 includes a first mating inclined surface 5311, and the second snap-fit ​​portion 62 includes a second mating inclined surface 621, so as to facilitate the inclined surface mating when the first snap-fit ​​portion 531 and the second snap-fit ​​portion 62 come into contact, which facilitates the first snap-fit ​​portion 531 being opened. As the first snap-fit ​​portion 531 moves toward the mounting base 60, the first mating inclined surface 5311 and the second mating inclined surface 621 are offset from each other, and the first snap-fit ​​portion 531 and the second snap-fit ​​portion 62 engage with each other.

[0067] In this embodiment of the application, the following combination is continued... Figure 3 and Figure 8 Both the operating arm 52 and the snap-fit ​​arm 53 are configured as elastic components. An annular pressing member 13 is constructed on the bottom wall 12 of the housing. At least one protruding support portion 21 is provided on the surface of the base 20 facing the bottom wall 12 of the housing. The projection of the support portion 21 on the bottom wall 12 of the housing is at least partially offset from the projection of the pressing member 13 on the bottom wall 12 of the housing. The support portion 21 and the support portion 51 are provided in a one-to-one correspondence, and the support portion 21 is used to movably support the corresponding support portion 51 on the pressing member 13.

[0068] Since the bearing portion 21 is used to movably support the corresponding support portion 51 on the pressing member 13, and the projection of the bearing portion 21 on the bottom wall is at least partially offset from the projection of the pressing member 13 on the bottom wall, when the operating arm 52 rotates around the bearing portion 21, the locking arm 53 can rotate accordingly with the rotation of the operating arm 52, so as to realize the release of the first locking portion 531 and the second locking portion 62.

[0069] The width dimension of the support part 21 (perpendicular to) Figure 8 The orientation of the drawing can be approximately the same as the corresponding support portion 51, and the number of bearing portions 21 is the same as that of the support portion 51.

[0070] The components included in the connecting unit 30 have elastic deformation capabilities. For example, at least the operating arm 52 and the locking arm 53 are elastic components capable of elastic deformation. Thus, when the support portion 51 is clamped between the inner wall of the housing 10 and the base 20, and the operating arm 52 rotates around the bearing portion 21, the locking arm 53 can better elastically deform accordingly with the rotation of the operating arm 52, thereby releasing the locking of the first locking portion 531 and the second locking portion 62.

[0071] In this embodiment, the surfaces of the support portion 51 and the bearing portion 21 facing each other are arc-shaped.

[0072] This configuration makes the relative rotation between the support portion 51 and the bearing portion 21 more stable, and makes the disengagement process between the first locking portion 531 and the second locking portion 62 of the locking arm 53 easier and more stable.

[0073] For example, combinedFigure 3 and Figure 8 The area of the first arc surface 511 of the support portion 51 facing the carrier portion 21 is greater than the area of the second arc surface 211 of the carrier portion 21 facing the support portion 51, so that the relative rotation of the support portion 51 relative to the carrier portion 21 is facilitated when the operating arm 52 is pressed. In addition, the third surface 212 of the carrier portion 21 adjacent to the second arc surface 211 is gradually concave in the direction of the radial inner side to provide a clearance for the rotation of the operating arm 52 caused by being pressed.

[0074] In the embodiment of the present application, the bottom wall 12 of the box body is provided with a cylindrical cover 121.

[0075] The base 20 is connected to the cover 121 and located inside the cover 121. The base 20 is spaced apart from the bottom wall 12 of the box body to define a first mounting cavity, and is spaced apart from the cover 121 to define a second mounting cavity. The operating arm 52 is located in the first mounting cavity, and the clamping arm 53 is located in the second mounting cavity.

[0076] In this way, the operating arm 52 is arranged adjacent to the bottom wall 12 of the box body, facilitating the operation of the operating arm 52 through the operation hole 11 in the bottom wall 12 of the box body. Exemplarily, when the box body 10 is installed on the frame, the cover 121 is arranged on the outer peripheral side of the mounting seat 60.

[0077] In addition, a ring-shaped pressing plate 122 can be connected to the end of the cover 121 away from the bottom wall 12 of the box body. In this way, the bottom of the base 20 can be supported on the pressing plate 122, and the top can be pressed against the crimping piece 13 through the support portion 51 of the connecting unit 30, so as to fix the base 20 inside the box body 10.

[0078] In the embodiment of the present application, in combination with Figure 3 , Figure 7 and Figure 8 The base 20 includes a base top wall 22 and a ring-shaped base side wall 23 connected to the base top wall 22. The base top wall 22 is arranged opposite to the bottom wall 12 of the box body, and the base side wall 23 is located between the cover 121 and the mounting seat 60. The carrier portion 21 is arranged on the base top wall 22.

[0079] The base side wall 23 is provided with a clearance notch 231 corresponding to the clamping arm 53, and the clamping arm 53 is partially arranged through the corresponding clearance notch 231, so that the first clamping portion 531 of the clamping arm 53 is clamped with the second clamping portion 62 on the mounting seat 60 inside the base side wall 23.

[0080] In the embodiment of the present application, in combination with Figure 3 and Figure 7 The base top wall 22 is partially protruded to the mounting seat 60 to form a protruding portion 220, and the base top wall 22 includes a first wall portion 221 surrounding the protruding portion 220.

[0081] The control box mounting structure 100 further comprises an auxiliary crimping piece 70. The auxiliary crimping piece 70 comprises a cover-shaped main body 71 with one end open, and a turned-up portion 72 connected to the open edge of the cover-shaped main body 71.

[0082] The cover-shaped main body 71 covers the outer circumferential side of the protruding portion 220, and defines a ring-shaped space 73 with the protruding portion 220, and the turned-up portion 72 is arranged opposite to the first wall portion 221. A first elastic piece 74 is arranged in the ring-shaped space 73, and the first elastic piece 74 is used to always apply an elastic force to the cover-shaped main body 71 away from the base top wall 22.

[0083] Since the first elastic piece 74 is used to always apply an elastic force to the cover-shaped main body 71 away from the base top wall 22, in the uninstalled state shown in Figure 7 , the turned-up portion 72 and the first wall portion 221 are actually arranged with a certain spacing, and after installation is completed (as shown in Figure 8 ), the turned-up portion 72 will be pressed against the top of the mounting seat 60 under the elastic force of the first elastic piece 74, so that the clamping connection of the first clamping portion 531 and the second clamping portion 62 is more stable. The two ends of the first elastic piece 74 respectively abut against the first wall portion 221 and the end of the cover-shaped main body 71.

[0084] Referring to Figure 3 , it can be understood that, in order to avoid the auxiliary crimping piece 70 from being separated from the base 20, the turned-up portion 72 is further provided with a plurality of anti-separation portions 721, the anti-separation portions 721 penetrate the base top wall 22 and can be clamped with the base top wall 22. The base top wall 22 can be provided with a plurality of matching holes 225, and the anti-separation portions 721 and the matching holes 225 one-to-one penetrate.

[0085] In some embodiments, continuing to refer to Figure 8 , after installation is completed, the turned-up portion 72 is arranged opposite to the top of the mounting seat 60, and a gasket 75, such as a rubber ring, can be further arranged between the turned-up portion 72 and the top of the mounting seat 60, so as to form a buffer between the turned-up portion 72 and the top of the mounting seat 60.

[0086] In the embodiments of the present application, referring to Figure 3 and Figure 8 , the second clamping portion 62 is configured as a ring-shaped protrusion arranged at the top end of the mounting seat 60. The number of the clamping assemblies 50 is multiple, the operation arms 52 of the multiple clamping assemblies 50 are connected through the connecting ribs 54, and the multiple clamping assemblies 50 are arranged at intervals along the circumference of the base 20. Exemplarily, the number of the clamping assemblies 50 is four.

[0087] In practice, multiple snap-fit ​​components 50 can be evenly distributed along the circumference of the base 20. The mounting base 60 can be formed as a cylindrical member with one end open, and the second snap-fit ​​portion 62 is formed at the edge of the opening of the cylindrical member. At this time, the cylindrical sidewall of the mounting base 60 can be located between the cover-shaped body 71 and the base sidewall 23.

[0088] In this embodiment of the application, the control box mounting structure 100 further includes a button 80, which presses against the end of the operating arm 52 away from the support portion 51. The operating arm 52 is used to disengage the first locking portion 531 and the second locking portion 62 of the locking arm 53 when it is pressed by the button 80 toward the mounting base 60.

[0089] Part of the button 80 is located in the operating hole 11 of the housing 10, making it convenient for the operator to operate the button 80 from the outside. The button 80 is also provided with a limiting part 81 in the middle, which is used to abut against the inner surface of the housing 10 to prevent the button 80 from coming out of the operating hole 11.

[0090] In the embodiments of this application, reference is made to Figure 9 The top wall 22 of the base is provided with a guide hole 222 corresponding to the position of the button 80. The end of the button 80 facing the mounting base 60 is guided and engaged with the guide hole 222. A second elastic member 24 is also provided between the top wall 22 of the base and the end of the operating arm 52 away from the support portion 51. The second elastic member 24 is used to always apply an elastic force away from the top wall 22 to the end of the operating arm 52 away from the support portion 51.

[0091] In a specific implementation, the protrusion 220 can be formed as a hollow structure. An annular guide seat 224 is provided on the surface of the protrusion 220 facing away from the mounting base 60, and a guide hole 222 is provided on the guide seat 224. The second elastic member 24 can be sleeved on the outer periphery of the guide seat 224. The two ends of the second elastic member 24 abut against the surface of the protrusion 220 facing away from the mounting base 60 and the end of the operating arm 52 away from the support portion 51, respectively.
