Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a controller installation structure and a circuit breaker. Background Art

[0002] Circuit breakers are important switchgear in power organizations, which can close, carry and disconnect current in the circuit. With the use of circuit breakers, more and more occasions require circuit breakers to have functions such as monitoring current and voltage, as well as pre-alarm, self-diagnosis, testing and regional interlocking, so it is necessary to set up a controller inside the circuit breaker.

[0003] The controllers currently used in circuit breakers have different sizes due to their different functions. However, the shell size of the same series of circuit breakers is fixed, or in other words, the distance between the base and the upper cover of the same series of circuit breakers is fixed, which brings inconvenience to the installation of controllers of different sizes in the shell. Utility Model Content

[0004] In view of the above problems, the present application provides a controller installation structure and a circuit breaker, which can reduce the difficulty of installing controllers of different sizes in a housing of fixed size.

[0005] In a first aspect, the present application provides a controller mounting structure for mounting a controller in a base of a circuit breaker, the controller mounting structure comprising a controller base, a bracket, a first adjusting member, and a second adjusting member. The controller base is fixedly mounted on the base. The bracket is fixedly mounted on a side of the controller base away from the base. The first adjusting member is connected to a first end of the controller, and a side of the first adjusting member facing the controller base abuts against the controller base to raise the first end of the controller. The second adjusting member is connected to the bracket, and a side of the second adjusting member facing the controller abuts against the second end of the controller to raise the second end of the controller.

[0006] Through the above scheme, the first adjustment member is connected to the first end of the controller, and the side of the first adjustment member facing the controller base is in contact with the controller base, so that in the covering direction of the base and the upper cover, the first adjustment member is at least partially located between the controller and the controller base, so that the first end of the controller can be raised by the first adjustment member. The second adjustment member is connected to the bracket, the bracket is fixedly installed on the controller base, and the side of the second adjustment member facing the controller is in contact with the second end of the controller, so that in the covering direction of the base and the upper cover, the second adjustment member is at least partially located between the bracket and the controller, so that the second end of the controller can be raised by the second adjustment member.

[0007] When the first end of the controller and the second end of the controller are both raised, the controller as a whole can be in the same and higher position. In this way, even if the size of the controller is small, it can be correctly installed in the housing while meeting the installation requirements through the adjustment of the first adjustment member and the second adjustment member, thereby reducing the difficulty of installing controllers of different sizes in a housing of fixed size.

[0008] In a possible design, a connecting ear is provided at the first end of the controller, a mounting opening is provided at the first adjusting member, and the first adjusting member is sleeved on the connecting ear through the mounting opening and connected to the connecting ear.

[0009] Through the above solution, the first adjusting member is easily and simply arranged on the connecting ear through the mounting opening, so that the arrangement of the first adjusting member does not increase the manufacturing difficulty and assembly difficulty of the controller mounting structure.

[0010] In a possible design, the first adjusting member includes a first plate, a second plate, and a third plate connected in sequence, the first plate and the third plate are bent relative to the second plate, and a mounting opening is formed between the first plate and the third plate.

[0011] The first plate, the second plate and the third plate are connected in sequence, so that the first adjusting member is in a U-shaped structure. The first adjusting member of the U-shaped structure can be sleeved on the connecting ear through the mounting opening formed between the first plate and the third plate, and connected to the connecting ear to achieve the connection between the first adjusting member and the first end of the controller.

[0012] In a possible design, the first plate is located on the side of the connecting ear facing away from the controller base, the third plate is located on the side of the connecting ear facing the controller base and abuts against the controller base, and the thickness of the third plate is greater than that of the first plate.

[0013] Through the above solution, the third plate is located between the connecting ear and the controller base, so that the thickness of the third plate determines the distance between the connecting ear and the controller base, thereby determining the degree to which the first end of the controller can be raised. Therefore, a third plate of appropriate thickness can be selected and replaced according to the size of the controller, so as to facilitate raising the first end of the controller to a suitable position.

[0014] In addition, the thickness of the third plate is set to be greater than that of the first plate, which, on the one hand, facilitates raising the connecting ear by the third plate having a larger thickness, thereby playing the role of raising the first end of the controller. On the other hand, the thickness of the first plate is smaller, and the first adjusting member and the connecting ear can be connected by connecting the first plate to the connecting ear, which can reduce the difficulty of connecting the first adjusting member and the connecting ear, and facilitate improving the reliability of the connection between the first adjusting member and the connecting ear.

[0015] In a possible design, the connecting ear is provided with a first limiting groove, the first adjusting member is partially located in the first limiting groove, and the first adjusting member located in the first limiting groove abuts against the groove wall of the first limiting groove in a first direction, wherein the first direction is perpendicular to the direction in which the first adjusting member is sleeved on the connecting ear.

[0016] Through the above scheme, the two groove walls of the first limiting groove in the first direction can limit the two sides of the first plate in the first direction, thereby limiting the movement of the first adjusting member in the first direction, thereby facilitating improving the connection reliability between the first adjusting member and the connecting ear, and then improving the connection reliability between the first adjusting member and the first end of the controller.

[0017] In a possible design, a first recess is provided on the groove wall of the first limiting groove, and a first boss is provided at a position opposite to the first recess of the first adjusting member, and the first boss is at least partially embedded in the first recess to limit the movement of the first adjusting member in the direction in which the first adjusting member is sleeved on the connecting ear.

[0018] Through the above scheme, the first boss on the first adjusting member is at least partially embedded in the first recess on the first limiting groove, so that the first recess can limit the first boss, reducing the possibility of the first adjusting member moving relative to the connecting ear in the direction in which the first adjusting member is sleeved on the connecting ear, thereby reducing the possibility of the first adjusting member slipping off the connecting ear.

[0019] In a possible design, the first adjustment member is made of elastic material, and a notch is provided at one end of the first plate away from the second plate. When the first adjustment member is mounted on the connecting ear, the parts on both sides of the notch are deformed toward the notch. When the first adjustment member is mounted on the connecting ear, the parts on both sides of the notch are deformed away from the notch, so that the first adjustment member abuts against the groove wall of the first limiting groove in the first direction.

[0020] According to the above scheme, when the first adjusting member is connected to the connecting ear, the parts of the first adjusting member located on both sides of the notch will be squeezed by the groove wall of the first limiting groove and move closer to each other, that is, the parts on both sides of the notch will deform toward the notch. When the first adjusting member is sleeved on the connecting ear and the first boss contacts the first notch, the parts on both sides of the notch recover and deform toward the first notch until the first boss is embedded in the first notch. In this way, the first adjusting member abuts against the groove wall of the first limiting groove in the first direction, which is convenient for improving the connection reliability of the first adjusting member on the connecting ear.

[0021] In a possible design, the bracket is provided with a mounting slot, a stopper is provided on one side of the mounting slot close to the controller base, and the second adjustment member is at least partially located in the mounting slot. One side of the second adjustment member is supported by the stopper, and the other side of the second adjustment member abuts against the second end of the controller.

[0022] Through the above solution, the second adjusting member is at least partially located in the mounting groove provided on the bracket, so that the second adjusting member can be installed on the bracket. One side of the second adjusting member is supported by a limit block provided on one side of the mounting groove close to the controller base, so that the position of the second adjusting member relative to the bracket can be fixed. Based on this, when the other side of the second adjusting member abuts against the second end of the controller, the second adjusting member can stably support and raise the second end of the controller.

[0023] In a possible design, the second adjustment member includes an adjustment column and a cushion block, one end of the adjustment column abuts against the cushion block, and the other end of the adjustment column abuts against the limit block, and the adjustment column is used to adjust the distance between the cushion block and the limit block.

[0024] Through the above scheme, one end of the adjustment column abuts against the cushion block, and the other end abuts against the limit block, so that the adjustment column can support the cushion block to adjust the height of the cushion block, thereby adjusting the height of the second end of the controller.

[0025] In a second aspect, the present application provides a circuit breaker, which includes a base, a controller, and the controller mounting structure in the first aspect, wherein the controller mounting structure is mounted on the base, and the controller is mounted on the controller mounting structure.

[0026] The beneficial effects of the circuit breaker provided in the second aspect and each possible design of the second aspect can refer to the beneficial effects brought about by the first aspect and each possible implementation method of the first aspect, which will not be repeated here.

[0047] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a barrier, such as a fixed connection through screws, bolts or other barrier; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0048] The present application provides a circuit breaker, which may be a frame circuit breaker, or other circuit breakers with controller requirements. The following is only an example of the frame circuit breaker shown in the accompanying drawings, but does not constitute a limitation on the technical solution of the present application.

[0049] Figure 1 A schematic diagram of a partial structure of a circuit breaker provided in an embodiment of the present application at a first viewing angle, Figure 2 A schematic diagram of a partial structure of a circuit breaker provided in an embodiment of the present application at a second viewing angle is shown in FIG. Figure 1 and Figure 2 As shown, the circuit breaker includes a base 100 , a controller 200 and a controller mounting structure 300 . The controller mounting structure 300 is mounted on the base 100 , and the controller 200 is mounted on the controller mounting structure 300 .

[0050] The housing of the circuit breaker includes not only the base 100 mentioned above, but also an upper cover (not shown in the figure). The base 100 and the upper cover cover each other, and after covering, an installation space is formed between the base 100 and the upper cover. The controller 200, the controller installation structure 300, and structures such as the contact system and the arc extinguishing system are all installed in the installation space.

[0051] For circuit breakers of the same series, the size of their housing is fixed. In the case where the housing includes a base 100 and an upper cover, the size of the housing is fixed, which means that the distance between the base 100 and the upper cover is fixed. The base 100 includes a bottom plate away from the upper cover, and the upper cover includes a top plate away from the base 100. The bottom plate and the top plate are substantially parallel and arranged along the covering direction of the base 100 and the upper cover. Based on this, the distance between the base 100 and the upper cover specifically refers to the distance between the bottom plate and the top plate.

[0052] The controller 200 may be a controller for monitoring current or voltage, or a controller for early warning, self-diagnosis, testing, and regional interlocking. Controllers 200 with different functions usually have different sizes. In addition, the controller 200 often has a built-in circuit board. The different sizes of the built-in circuit board will also make the sizes of the controllers 200 different.

[0053] When the distance between the base 100 and the upper cover is fixed, if a controller 200 of suitable size is installed in the housing, the installation requirements can be met. However, if a controller 200 of smaller size is installed in the housing, the controller 200 installed in the housing may shake during use, which cannot meet the installation requirements.

[0054] In view of this, the embodiment of the present application sets a controller installation structure 300 in the circuit breaker, and the controller 200 is installed in the housing through the controller installation structure 300, so that the controllers 200 of different sizes can maintain the same height after being installed on the base 100. In this way, the controllers 200 of different sizes can meet the installation requirements when installed in the housing, reducing the difficulty of installing the controllers 200 of different sizes into the housing of fixed size.

[0055] The specific structure of the controller installation structure 300 will be described in detail below in conjunction with the accompanying drawings. In addition, the specific implementation of the controller installation structure 300 being installed on the base 100 and the controller 200 being installed on the controller installation structure 300 will be described in detail.

[0056] Figure 3 for Figure 1 An exploded view of the structure shown, Figure 4 for Figure 2 The present application provides a controller installation structure 300, which is used to install the controller 200 in the base 100 of the circuit breaker. Figure 3 and Figure 4 As shown, the controller installation structure 300 includes a controller base 310 , a bracket 320 , a first adjustment member 330 and a second adjustment member 340 .

[0057] The controller base 310 is fixedly mounted on the base 100. The bracket 320 is fixedly mounted on a side of the controller base 310 away from the base 100. The first adjustment member 330 is connected to the first end of the controller 200, and the side of the first adjustment member 330 facing the controller base 310 abuts against the controller base 310 to raise the first end of the controller 200. The second adjustment member 340 is connected to the bracket 320, and the side of the second adjustment member 340 facing the controller 200 abuts against the second end of the controller 200 to raise the second end of the controller 200.

[0058] The controller base 310 can be fixedly mounted on the base 100 by fasteners. For example, the controller base 310 can be provided with a first through hole, and the base 100 can be provided with a second through hole at a position opposite to the first through hole. The fasteners are passed through the first through hole and the second through hole and connected with the first through hole and the second through hole, so that the connection between the controller base 310 and the base 100 can be achieved.

[0059] Of course, the controller base 310 can also be connected to the base 100 by plugging or snapping, etc., which is not limited in the embodiment of the present application.

[0060] like Figure 2As shown, the bracket 320 may include a support plate 321 and a connecting plate 322 , and the support plate 321 is substantially perpendicular to the connecting plate 322 .

[0061] The connecting plate 322 is substantially parallel to the controller base 310 and in contact with the controller base 310. The connecting plate 322 can be connected to the controller base 310 to achieve the installation of the bracket 320 on the side of the controller base 310 away from the base 100. Similar to the connection between the controller base 310 and the base 100, the connecting plate 322 can be connected to the controller base 310 by fastener connection, plug-in or snap-in. The specific implementation of the above connection method can refer to the above description and related technologies, which will not be expanded here.

[0062] The support plate 321 extends toward the controller 200 relative to the connecting plate 322, and the support plate 321 can be connected to the second adjusting member 340 to achieve the connection between the bracket 320 and the second adjusting member 340. The connection method between the bracket 320 and the second adjusting member 340 will be introduced later and will not be expanded here.

[0063] The connection method between the first adjusting member 330 and the first end of the controller 200 will also be introduced later and will not be expanded here.

[0064] The first adjusting member 330 and the second adjusting member 340 may be in any shape such as a block or a plate.

[0065] The first adjusting member 330 is connected to the first end of the controller 200, that is, the first adjusting member 330 is installed at the first end of the controller 200. Assuming that the portion of the first end of the controller 200 connected to the first adjusting member 330 is called the first connection, the first adjusting member 330 connected to the first end of the controller 200 in the present application at least partially protrudes from the first connection toward the controller base 310. That is to say, in the covering direction of the base 100 and the upper cover, the first adjusting member 330 is at least partially located between the first connection and the controller base 310.

[0066] In this configuration, when the first adjustment member 330 is connected to the first end of the controller 200 and the controller 200 is mounted on the controller base 310, the side of the first adjustment member 330 facing the controller base 310 will abut against the controller base 310, rather than the controller 200 directly abutting against the controller base 310. In this way, the first end of the controller 200 can be raised by the first adjustment member 330.

[0067] The second adjusting member 340 is connected to the bracket 320, and the bracket 320 is fixedly mounted on the controller base 310, so the second adjusting member 340 can be mounted on the controller base 310 through the bracket 320. Assuming that the part of the bracket 320 connected to the second adjusting member 340 is called the second connection, the second adjusting member 340 connected to the bracket 320 in the present application at least partially protrudes from the second connection toward the second end of the controller 200. That is to say, in the covering direction of the base 100 and the upper cover, the second adjusting member 340 is at least partially located between the second connection and the second end of the controller 200.

[0068] In this configuration, when the second adjusting member 340 is mounted on the controller base 310 via the bracket 320 and the controller 200 is mounted on the bracket 320, the side of the second adjusting member 340 facing the controller 200 will abut against the second end of the controller 200, rather than the controller 200 directly abutting against the bracket 320. In this way, the second end of the controller 200 can be raised by the second adjusting member 340.

[0069] The first end of the controller 200 is relative to the second end of the controller 200, the first adjusting member 330 is arranged close to the first end of the controller 200, and the second adjusting member 340 is arranged close to the second end of the controller 200. When the first adjusting member 330 raises the first end of the controller 200 and the second adjusting member 340 raises the second end of the controller 200, the first end and the second end of the controller 200 can be in the same and higher position, so that a smaller controller 200 can be installed in the housing and meet the installation requirements.

[0070] In summary, the first adjustment member 330 is connected to the first end of the controller 200, and the side of the first adjustment member 330 facing the controller base 310 abuts against the controller base 310, so that in the covering direction of the base 100 and the upper cover, the first adjustment member 330 is at least partially located between the controller 200 and the controller base 310, so that the first end of the controller 200 can be raised by the first adjustment member 330. The second adjustment member 340 is connected to the bracket 320, and the bracket 320 is fixedly installed on the controller base 310, and the side of the second adjustment member 340 facing the controller 200 abuts against the second end of the controller 200, so that in the covering direction of the base 100 and the upper cover, the second adjustment member 340 is at least partially located between the bracket 320 and the controller 200, so that the second end of the controller 200 can be raised by the second adjustment member 340.

[0071] When the first end of the controller 200 and the second end of the controller 200 are both raised, the controller 200 as a whole can be in the same and higher position. In this way, even if the size of the controller 200 is small, it can be properly installed in the housing under the condition of meeting the installation requirements through the adjustment of the first adjustment member 330 and the second adjustment member 340, reducing the difficulty of installing controllers 200 of different sizes in a housing of fixed size.

[0072] It should be noted that the sizes of the first adjusting member 330 and the second adjusting member 340 can be adjusted according to the size of the controller 200. Through the adjustment of the first adjusting member 330 and the second adjusting member 340, the controllers 200 of different sizes can be at the same height after being installed on the base 100. In this way, the controllers 200 of different sizes can be installed in the housing of the same size.

[0073] In addition, since the size of the second adjusting member 340 can be adjusted according to the size of the controller 200, and the structure of the second adjusting member 340 is relatively simple compared to the structure of the bracket 320, when adjusting the height of the second end of the controller 200, the present application can be achieved by only adjusting the size of the second adjusting member 340 without adjusting the structure of the bracket 320. In this way, the mold opening cost of the bracket 320 will not be increased, and thus the manufacturing cost of the controller mounting structure 300 will not be increased.

[0074] Combine the following Figures 1 to 6 The structure of the first adjusting member 330 in the embodiment of the present application is introduced in detail.

[0075] Figure 5 for Figure 4 The enlarged view of part A in the figure. Figure 6 A schematic diagram of the structure of a first adjusting member provided in an embodiment of the present application, combined with Figures 4 to 6 The first end of the controller 200 may be provided with a connecting ear 210 , and the first adjusting member 330 may be provided with a mounting opening 331 . The first adjusting member 330 is sleeved on the connecting ear 210 through the mounting opening 331 and connected to the connecting ear 210 .

[0076] The connecting ear 210 may be a protruding structure provided at the first end of the controller 200 facing away from the second end of the controller 200 . The connecting ear 210 may be in any shape such as a cylinder or a cube.

[0077] The first adjusting member 330 may be cylindrical with a blind groove at one end. In this case, the blind groove is the above-mentioned installation opening 331. Figure 6 The U-shaped block structure shown in the figure, in this case, the U-shaped opening is the above-mentioned installation opening 331.

[0078] The first adjusting member 330 is sleeved on the connecting ear 210 through the mounting opening 331, and the first adjusting member 330 can be interference fit with the connecting ear 210 to achieve the connection between the first adjusting member 330 and the connecting ear 210. After the first adjusting member 330 is sleeved on the connecting ear 210, the first adjusting member 330 and the connecting ear 210 can also be fastened by screws to achieve the connection between the first adjusting member 330 and the connecting ear 210. Of course, there are other ways such as plug-in or snap-in to achieve the connection between the first adjusting member 330 and the connecting ear 210, which are not listed one by one in this application.

[0079] The first adjusting member 330 is simply and easily sleeved on the connecting ear 210 through the mounting opening 331 , so that the arrangement of the first adjusting member 330 does not increase the manufacturing difficulty and the assembly difficulty of the controller mounting structure 300 .

[0080] Based on the above description, the adjusting member may be a U-shaped block structure, for example, Figure 6 As shown, the first adjusting member 330 includes a first plate 332 , a second plate 333 and a third plate 334 connected in sequence. The first plate 332 and the third plate 334 are bent relative to the second plate 333 , and a mounting opening 331 is formed between the first plate 332 and the third plate 334 .

[0081] The first plate 332 is connected to one side of the second plate 333 in the covering direction of the base 100 and the upper cover, and the third plate 334 is connected to the other side of the second plate 333 in the covering direction of the base 100 and the upper cover. The first plate 332 and the third plate 334 have a non-zero gap in the covering direction of the base 100 and the upper cover, so that a mounting opening 331 can be formed between the first plate 332 and the third plate 334.

[0082] The first plate 332 , the second plate 333 , and the third plate 334 may be integrally formed to save assembly steps.

[0083] The first plate 332, the second plate 333 and the third plate 334 may also be formed separately, in which case it is convenient to replace any one of the three as needed.

[0084] The first plate 332, the second plate 333 and the third plate 334 are connected in sequence, so that the first adjusting member 330 is in a U-shaped structure. The first adjusting member 330 in the U-shaped structure can be sleeved on the connecting ear 210 through the mounting opening 331 formed between the first plate 332 and the third plate 334, and connected to the connecting ear 210, so as to realize the connection between the first adjusting member 330 and the first end of the controller 200.

[0085] Among them, when the first adjustment member 330 of the U-shaped structure is sleeved on the connecting ear 210, the first plate 332 and the third plate 334 can contact the opposite sides of the connecting ear 210 in the covering direction of the base 100 and the upper cover, and can also contact the other two opposite side walls of the connecting ear 210. The embodiment of the present application is not limited to this, as long as the first adjustment member 330 is sleeved on the connecting ear 210, it can be at least partially located between the connecting ear 210 and the controller base 310.

[0086] In the case where the first plate 332 and the third plate 334 are in contact with the connecting ears 210 on opposite sides in the covering direction of the base 100 and the upper cover, for example, please continue to refer to Figure 4 and Figure 6 The first plate 332 can be located on the side of the connecting ear 210 facing away from the controller base 310, and the third plate 334 can be located on the side of the connecting ear 210 facing the controller base 310 and abut against the controller base 310, and the thickness of the third plate 334 is greater than the thickness of the first plate 332.

[0087] The third plate 334 is arranged so that it is located between the connecting ear 210 and the controller base 310. Thus, the thickness of the third plate 334 determines the distance between the connecting ear 210 and the controller base 310, thereby determining the degree to which the first end of the controller 200 can be raised. Therefore, the third plate 334 of appropriate thickness can be selected and replaced according to the size of the controller 200, so as to facilitate raising the first end of the controller 200 to a suitable position.

[0088] In addition, the thickness of the third plate 334 is set to be greater than the thickness of the first plate 332. On the one hand, it is convenient to raise the connecting ear 210 through the third plate 334 with a larger thickness, thereby playing a role of raising the first end of the controller 200. On the other hand, the thickness of the first plate 332 is relatively small, and the first adjusting member 330 can be connected to the connecting ear 210 by connecting the first plate 332 to the connecting ear 210, so that the difficulty of connecting the first adjusting member 330 to the connecting ear 210 can be reduced, and the reliability of the connection between the first adjusting member 330 and the connecting ear 210 can be improved.

[0089] In some embodiments, Figure 5 As shown, the connecting ear 210 may be provided with a first limiting groove 211. Figures 4 to 6 The first adjusting member 330 is partially located in the first limiting groove 211 , and the first adjusting member 330 located in the first limiting groove 211 abuts against the groove wall of the first limiting groove 211 in the first direction.

[0090] The first direction is perpendicular to the direction in which the first adjusting member 330 is sleeved on the connecting ear 210 , and is also perpendicular to the covering direction of the base 100 and the upper cover.

[0091] Combination Figure 4 and Figure 5 The first limiting groove 211 can be arranged on the side of the connecting ear 210 facing away from the controller base 310. Of course, the first limiting groove 211 can also be arranged on the side of the connecting ear 210 facing the controller base 310.

[0092] by Figures 4 to 6 Taking the structure shown as an example, the first adjusting member 330 is partially located in the first limiting groove 211, which means that the first plate 332 in the first adjusting member 330 is located in the first limiting groove 211. The first limiting groove 211 has two groove walls that are opposite to each other in the first direction. When the first plate 332 is located in the first limiting groove 211, one side of the first plate 332 in the first direction abuts against one groove wall of the first limiting groove 211 in the first direction, and the other side of the first plate 332 in the first direction abuts against the other groove wall of the first limiting groove 211 in the first direction.

[0093] In this way, the two groove walls of the first limiting groove 211 in the first direction can limit the two sides of the first plate 332 in the first direction, thereby limiting the movement of the first adjusting member 330 in the first direction, thereby facilitating the improvement of the connection reliability between the first adjusting member 330 and the connecting ear 210, and further improving the connection reliability between the first adjusting member 330 and the first end of the controller 200.

[0094] Based on the previous description, please continue to refer to Figures 4 to 6 In some embodiments, the groove wall of the first limiting groove 211 may be provided with a first recess 2111, and the first boss 335 is provided at a position opposite to the first recess 2111 of the first adjusting member 330, and the first boss 335 is at least partially embedded in the first recess 2111 to limit the movement of the first adjusting member 330 in the direction in which the first adjusting member 330 is sleeved on the connecting ear 210.

[0095] The first notch 2111 may be provided only on one groove wall of the first limiting groove 211 in the first direction, and accordingly, the first boss 335 may be provided only on one side of the first adjusting member 330 in the first direction. The first notch 2111 may also be provided on two groove walls of the first limiting groove 211 in the first direction, and accordingly, the first boss 335 may also be provided on both sides of the first adjusting member 330 in the first direction.

[0096] The number of the first recesses 2111 may be the same as the number of the first bosses 335, and may be one or more. For example, when the number of the first recesses 2111 is one, the number of the corresponding first bosses 335 is also one. When the number of the first recesses 2111 is multiple, the number of the first bosses 335 may also be multiple, and the multiple first bosses 335 correspond to the multiple first recesses 2111 one by one.

[0097] Figures 4 to 6 The first notch 2111 shown in the figure is provided at the first limiting groove 211 provided at the side of the connecting ear 210 facing away from the controller base 310, and the first boss 335 is provided at the first plate 332. In practice, the first notch 2111 may also be provided at the first limiting groove 211 provided at the side of the connecting ear 210 facing the controller base 310, and correspondingly, the first boss 335 may be provided at the third plate 334, which is not limited in the embodiment of the present application.

[0098] Through the above scheme, the first boss 335 on the first adjusting member 330 is at least partially embedded in the first recess 2111 on the first limiting groove 211, so that the first recess 2111 can limit the first boss 335, thereby reducing the possibility of the first adjusting member 330 moving relative to the connecting ear 210 in the direction in which the first adjusting member 330 is sleeved on the connecting ear 210, thereby reducing the possibility of the first adjusting member 330 slipping off the connecting ear 210.

[0099] In some embodiments, the first adjusting member 330 may be made of an elastic material. Figure 6 As shown, a notch 3321 may be provided at one end of the first plate 332 away from the second plate 333. Figures 4 to 6 When the first adjusting member 330 is sleeved on the connecting ear 210, the parts on both sides of the notch 3321 are deformed toward the notch 3321. When the first adjusting member 330 is sleeved on the connecting ear 210, the parts on both sides of the notch 3321 are deformed back to the notch 3321, so that the first adjusting member 330 abuts against the groove wall of the first limiting groove 211 in the first direction.

[0100] The first adjusting member 330 may be made of any elastic material such as rubber, plastic, silicone or a composite material.

[0101] The notch 3321 may be in any shape such as circular, square or diamond. The notch 3321 may penetrate the end surface of the first plate 332 away from the second plate 333, or may not penetrate the end surface of the first plate 332 away from the second plate 333, which is not limited in the embodiment of the present application.

[0102] Since the first adjusting member 330 is made of elastic material, a first boss 335 is provided on the first adjusting member 330, and a notch 3321 is provided on the end of the first plate 332 away from the second plate 333. When the first adjusting member 330 is sleeved onto the connecting ear 210, the parts of the first adjusting member 330 on both sides of the notch 3321 will be squeezed by the groove wall of the first limiting groove 211 and approach each other, that is, the parts on both sides of the notch 3321 will be deformed toward the notch 3321.

[0103] Generally, elastic materials have a tendency to recover after deformation, so when the first adjusting member 330 is sleeved on the connecting ear 210 and the first boss 335 contacts the first notch 2111, the parts on both sides of the notch 3321 recover and deform toward the first notch 2111 until the first boss 335 is embedded in the first notch 2111. In this way, the first adjusting member 330 abuts against the groove wall of the first limiting groove 211 in the first direction, which facilitates improving the connection reliability of the first adjusting member 330 on the connecting ear 210.

[0104] After introducing the structure of the first adjusting member 330, Figure 3 , Figures 7 to 9 The structure of the second adjusting member 340 in the embodiment of the present application is introduced in detail.

[0105] Figure 7 for Figure 3 The enlarged view of part B in the middle, combined with Figure 1 , Figure 3 and Figure 7 The bracket 320 is provided with a mounting groove 323, and a stopper 324 is provided on one side of the mounting groove 323 close to the controller base 310, and the second adjustment member 340 is at least partially located in the mounting groove 323. One side of the second adjustment member 340 is supported by the stopper 324, and the other side of the second adjustment member 340 is in contact with the second end of the controller 200.

[0106] The mounting groove 323 can be arranged along the covering direction of the base 100 and the upper cover. Figure 3 and Figure 7 The limiting block 324 is located on one side of the mounting slot 323 close to the controller base 310 .

[0107] The shape of the limiting block 324 can be regular or irregular, as long as the limiting block 324 can play a role in supporting the second adjusting member 340 .

[0108] The second adjusting member 340 is at least partially located in the mounting groove 323 provided on the bracket 320, so that the second adjusting member 340 can be installed on the bracket 320. One side of the second adjusting member 340 is supported by a stopper 324 provided on one side of the mounting groove 323 close to the controller base 310, so that the position of the second adjusting member 340 relative to the bracket 320 can be fixed. Based on this, when the other side of the second adjusting member 340 abuts against the second end of the controller 200, the second adjusting member 340 can stably support and raise the second end of the controller 200.

[0109] Regarding the structural form of the second adjusting member 340, in some possible cases, the second adjusting member 340 may only include a block structure of any shape. In other possible cases, the second adjusting member 340 may include a plurality of structural members used in cooperation with each other.

[0110] Figure 8 A schematic diagram of the structure of a cushion block provided in an embodiment of the present application at a first viewing angle, Fig. 9 A schematic diagram of the structure of a cushion block provided in an embodiment of the present application at a second viewing angle, in which the second adjusting member 340 includes a plurality of structural members used in conjunction with each other, such as Figure 8 and Fig. 9 As shown, the plurality of structural members may be adjustment columns (not shown in the figure) and spacers 342 .

[0111] Exemplarily, the second adjusting member 340 includes an adjusting column and a cushion block 342 , one end of the adjusting column abuts against the cushion block 342 , and the other end of the adjusting column abuts against the limit block 324 , and the adjusting column is used to adjust the distance between the cushion block 342 and the limit block 324 .

[0112] The adjusting column can be cylindrical or prismatic. The pad 342 can be any regular or irregular shape.

[0113] The pad 342 is installed in the installation groove 323 along the covering direction of the base 100 and the upper cover. The adjustment column is located between the pad 342 and the limit block 324 in the covering direction of the base 100 and the upper cover, and one end of the adjustment column abuts against the pad 342, and the other end abuts against the limit block 324, so that the position of the adjustment column between the pad 342 and the limit block 324 can be fixed.

[0114] Furthermore, one end of the adjustment column may also be bonded to the pad 342. Fig. 9 As shown, a second limiting groove 3421 may be provided on one side of the cushion block 342 facing the limiting block 324, and one end of the adjustment column may be located in the second limiting groove 3421 and abut against the bottom of the second limiting groove 3421. In this way, the groove wall of the second limiting groove 3421 may limit the adjustment column, reducing the possibility of the adjustment column tilting.

[0115] One end of the adjustment column abuts against the cushion block 342 , and the other end abuts against the limit block 324 , so that the adjustment column can support the cushion block 342 to adjust the height of the cushion block 342 , thereby adjusting the height of the second end of the controller 200 .

[0116] Similar to the structure of the first adjusting member 330, in some embodiments, the groove wall of the installation groove 323 may be provided with a second recess 3231, and a second boss 3422 may be provided at a position opposite to the second recess 3231. The second boss 3422 is at least partially embedded in the second recess 3231, so as to limit the cushion block 342 through the cooperation between the second protrusion and the second recess 3231, thereby reducing the possibility of the cushion block 342 moving in a direction perpendicular to its installation direction.
