[0076] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0077] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0078] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0079] In the present application, unless otherwise clearly defined and limited, if there are terms such as "mounted", "connected", "connected to", "fixed", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. 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.

[0080] In the present application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0081] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can be an intermediate element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0082] In the related art, a switch module may include a housing, a circuit board, and a relay. The relay is electrically connected to the circuit board, and both the circuit board and the relay can be disposed in the housing.

[0083] However, the relay and other devices of the switch module are all disposed on the same circuit board, making the area of the circuit board large, thereby making the volume of the housing large and the volume of the switch module large.

[0084] To solve the above problems, the embodiments of the present application provide a switch module and an electronic device, which can reduce the volume of the switch module.

[0085] The following will be combined with Figures 1 - 12 to describe the switch module 100 and the electronic device 10 provided by the embodiments of the present application.

[0086] Referring to Figure 1 , the embodiments of the present application provide a switch module 100. The switch module 100 includes a housing 101, a first circuit board 131, and a second circuit board 132. The housing 101 can be provided with a receiving cavity 102. The first circuit board 131 and the second circuit board 132 can both be disposed in the receiving cavity 102. The first circuit board 131 and the second circuit board 132 are spaced apart along a first direction A, and the first circuit board 131 is connected to the second circuit board 132, thereby realizing signal transmission between the first circuit board 131 and the second circuit board 132. Among them, the first circuit board 131 and the second circuit board 132 being spaced apart along the first direction A can mean that there is a distance between the first circuit board 131 and the second circuit board 132 along the first direction A.

[0087] The switch module 100 includes a relay 133. The relay 133 is disposed between the first circuit board 131 and the second circuit board 132, and the relay 133 is connected to at least one of the first circuit board 131 and the second circuit board 132. The relay 133 can control a circuit with a larger current with a smaller current. The relay 133 can be connected to the first circuit board 131, or the first circuit board 131 can be connected to the second circuit board 132, or the relay 133 can be connected to both the first circuit board 131 and the second circuit board 132 at the same time.

[0088] Thus, by providing two circuit boards (the first circuit board 131 and the second circuit board 132), different devices within the accommodation cavity 102 can be distributed on the first circuit board 131 and the second circuit board 132, and the first circuit board 131 and the second circuit board 132 can be stacked along the first direction A, which can reduce the total area of the first circuit board 131 and the second circuit board 132, facilitating the reduction of the volume of the housing 101, and further reducing the volume of the switch module 100.

[0089] Refer to Figure 4 , the housing 101 includes a connected first sub-housing 110 and a second sub-housing 120, and the first sub-housing 110 and the second sub-housing 120 can be arranged along the first direction A. The dimension L2 of the second sub-housing 120 along the second direction B is smaller than the dimension L1 of the first sub-housing 110 along the second direction B, that is, the dimension L2 of the second sub-housing 120 along the second direction B is set to be smaller, and the dimension L1 of the first sub-housing 110 along the second direction B is set to be larger.

[0090] Thus, by setting the dimension of the second sub-housing 120 along the second direction B to be smaller, when the housing 101 is installed with the box body 210, it is beneficial to avoid interference between the second sub-housing 120 and other structures within the box body 210. In addition, by setting the dimension of the first sub-housing 110 along the second direction B to be larger, the volume within the first sub-housing 110 is larger, and more devices can be accommodated within the first sub-housing 110, making the devices within the housing 101 more concentrated. The larger-sized first sub-housing 110 can provide better support for each device, and the first sub-housing 110 can effectively bear the weight of the devices, avoiding excessive local pressure on the first sub-housing 110.

[0091] Exemplarily, refer to Figure 2a , the switch module 100 can have a first direction A, a second direction B, and a third direction C, and the first direction A, the second direction B, and the third direction C are all different. For example, the first direction A, the second direction B, and the third direction C can be perpendicular to each other pairwise. Exemplarily, the first direction A can be the height direction of the switch module 100, the second direction B can be the width direction of the switch module 100, and the third direction C can be the length direction of the switch module 100. The length, width, height, etc. in the embodiments of the present application are only for convenience of description and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length.

[0092] In some embodiments, refer to Figure 4The first sub-housing 110 and the second sub-housing 120 are arranged along the direction from the first circuit board 131 to the second circuit board 132, that is, the arrangement direction of the first sub-housing 110 and the second sub-housing 120 is the same as the arrangement direction of the first circuit board 131 and the second circuit board 132. The first circuit board 131 and the relay 133 are both arranged in the accommodating cavity 102 of the first sub-housing 110. Since the volume of the relay 133 and the first circuit board is generally large, they are concentrated in a larger accommodating cavity 102 of the first sub-housing 110, which is conducive to reducing the volume of the housing 101.

[0093] The orthographic projection of the second circuit board 132 on the plane where the first circuit board 131 is located is located within the orthographic projection of the first circuit board 131 on the plane where the first circuit board 131 is located. The area of ​​the second circuit board 132 is set to be smaller, and the area of ​​the first circuit board 131 is set to be larger. The second circuit board 132 and the first circuit board 131 are arranged relative to each other along the thickness direction, which is beneficial to reducing the total area occupied by the first circuit board 131 and the second circuit board 132, and is beneficial to reducing the volume of the shell 101.

[0094] In some embodiments, see Figure 5 The orthographic projection of the relay 133 on the plane where the first circuit board 131 is located is located within the orthographic projection of the second circuit board 132 on the plane where the first circuit board 131 is located. The second circuit board 132 completely covers the relay 133. The sizes of the two are matched with each other, which is beneficial to reducing the total area occupied by the second circuit board 132 and the relay 133, and is beneficial to reducing the volume of the housing 101.

[0095] In some other embodiments, the orthographic projection of the relay 133 on the plane where the first circuit board 131 is located does not at least partially overlap with the orthographic projection of the second circuit board 132 on the plane where the first circuit board 131 is located, and the second circuit board 132 partially covers the relay 133, or the surface of the relay 133 facing away from the first circuit board 131 is completely exposed outside the second circuit board 132, and the second circuit board 132 does not cover the relay 133, so that at least a portion of the second circuit board 132 is far away from the relay 133, which can reduce the adverse effects of the heat of the relay 133 on the devices on the second circuit board 132.

[0096] In some embodiments, one of the first circuit board 131 and the second circuit board 132 is connected to the relay 133, that is, the relay 133 is installed on one of the first circuit board 131 and the second circuit board 132, and a control circuit is provided on the other of the first circuit board 131 and the second circuit board 132, and the control circuit is electrically connected to the relay 133, and the control circuit can control the relay 133. That is, the relay 133 is provided on the first circuit board 131, and the control circuit is provided on the second circuit board 132. Alternatively, the relay 133 is provided on the second circuit board 132, and the control circuit is provided on the first circuit board 131. In this way, the relay 133 and the control circuit are respectively provided on different circuit boards. When a problem occurs in the control circuit or the relay 133, the circuit board with the problem can be replaced alone without replacing both circuit boards, which is conducive to reducing maintenance costs.

[0097] In an embodiment in which a control circuit is provided on the second circuit board 132, the area of ​​the second circuit board 132 is smaller than the area of ​​the first circuit board 131, and the volume of the control circuit can be smaller than the volume of the relay 133. The smaller control circuit is arranged on the second circuit board 132, which is beneficial to reducing the total volume of the second circuit board 132 and the control circuit, and is beneficial to reducing the volume of the shell 101.

[0098] In some embodiments, see Figure 4 , a first type device 134 is provided on the second circuit board 132. For example, the first type device 134 is provided on a side of the second circuit board 132 facing the first circuit board 131, and the first type device 134 is provided on a side of the second circuit board 132 away from the first shell wall 121, and there is no need to reserve space for the first type device 134 between the second circuit board 132 and the first shell wall 121, so that the distance between the second circuit board 132 and the first shell wall 121 along the first direction A is small, and the button 135 ( Figure 6 ) is closer to the first shell wall 121, the length of the operating member is shorter, and it is easier to press the button 135.

[0099] In other embodiments, the first type device 134 can be arranged on the side of the second circuit board 132 away from the first circuit board 131. The first type device 134 is arranged on the side of the second circuit board 132 away from the relay 133, and the relay 133 and the first type device 134 are respectively arranged on both sides of the second circuit board 132. This can make the first type device 134 farther away from the relay 133, and can reduce the adverse effect of the heat of the relay 133 on the first type device 134.

[0100] In some embodiments, a second type of device may be provided on the second circuit board 132. The volumes of the first type of device 134 and the second type of device may be different. For example, the volume of the first type of device 134 may be greater than or less than that of the second type of device. And / or, the first type of device and the second type of device may have different degrees of thermal sensitivity. For example, the first type of device 134 is more sensitive to heat.

[0101] Exemplarily, the first type of device 134 includes a thermal sensor device. When the first type of device 134 is disposed on the side of the second circuit board 132 away from the first circuit board 131, the adverse effect of the heat of the relay 133 on the thermal sensor device can be reduced.

[0102] In some embodiments, referring to Figure 6 , a key 135 is provided on the second circuit board 132. The key 135 is disposed on the side of the second circuit board 132 away from the first circuit board 131. The switch module 100 includes an operating member, and the operating member is connected to the key 135. By pressing the operating member, the key 135 can be pressed, and thus the devices in the housing 101 can be controlled to work. The second sub-housing 120 includes a first housing wall 121 ( Figure 4 ), the first housing wall 121 is disposed at one end of the second sub-housing 120 away from the first sub-housing 110. An operating portion is provided on the first housing wall 121, and the operating portion is connected to the operating member. The operating portion and the operating member can be disposed opposite to each other in the first direction A. One end of the operating member away from the operating portion is connected to the key 135. By pressing the operating portion, it is convenient for the operator to press the operating member. For example, the operating portion may have a certain elasticity. When the operating portion is pressed, the operating portion can be deformed to drive the operating member to press the key 135.

[0103] It should be noted that the operating portion may be indirectly connected to the key 135. For example, the operating portion may be connected to the key 135 through the operating member. In this way, the setting positions of the operating portion and the key 135 are more flexible. Or, the operating portion may be directly connected to the key 135, and no other structure is required to connect the operating portion and the key 135, which can simplify the structure of the switch module 100 and reduce the manufacturing cost.

[0104] Exemplarily, the operating portion may extend in a direction parallel to the first circuit board 131, and the operating portion has a certain length in the direction parallel to the first circuit board 131, which is convenient for the operating portion to have elasticity.

[0105] In some embodiments, referring to Figure 6, a light-emitting component 140 is provided on the second circuit board 132, and the light-emitting component 140 is disposed on a side of the second circuit board 132 facing away from the first circuit board 131. For example, the light-emitting component 140 can be an LED lamp. A light guide column 136 is disposed on a side of the light-emitting component 140 facing away from the second circuit board 132. Since the light-emitting component 140 is relatively far from the surface of the housing 101, the light emitted by the light-emitting component 140 can be conducted to the surface of the housing 101 through the light guide column 136.

[0106] In some embodiments, referring to Figure 7 , the switch module 100 includes a first support member 141. The first end of the first circuit board 131 and the first end of the second circuit board 132 are connected by the first support member 141. The first support member 141 can be used to support the second circuit and can also maintain the distance between the first circuit board 131 and the second circuit board 132. The mechanical strength of the first support member 141 can be relatively high, which is beneficial to improving the connection stability between the first circuit board 131 and the second circuit board 132.

[0107] Among them, the first end and the second end of the first circuit board 131 can be opposite ends along the second direction B, or the first end and the second end of the first circuit board 131 can be opposite ends along the third direction Y, or the first end and the second end of the first circuit board 131 can be opposite ends along other directions, and the other direction can be parallel to the first circuit board 131. The direction from the first end to the second end of the first circuit board 131 is the same as the direction from the first end to the second end of the second circuit board 132.

[0108] Exemplarily, the number of the first support members 141 is at least one. When there are multiple first support members 141, the multiple first support members 141 can be arranged at intervals. The multiple first support members 141 being arranged at intervals can mean that there is a spacing between adjacent two first support members 141.

[0109] In some embodiments, referring to Figure 6 , the switch module 100 includes a pin 137. The second end of the first circuit board 131 and the second end of the second circuit board 132 are connected by the pin 137. The connection between the first circuit board 131 and the second circuit board 132 is realized through the pin 137, making the communication between the first circuit board 131 and the second circuit board 132 more reliable. In addition, the pin 137 has a certain mechanical strength and can play a certain supporting role for the second circuit board 132, which can improve the connection reliability between the first circuit board 131 and the second circuit board 132.

[0110] In an embodiment where both the pin 137 and the first support member 141 are provided, the pin 137 and the first support member 141 can be arranged at intervals. The pin 137 and the first support member 141 being arranged at intervals can mean that there is a spacing between the pin 137 and the first support member 141.

[0111] In some embodiments, referring to Figure 13 , the switch module 100 includes a flexible circuit board 144. The first circuit board 131 and the second circuit board 132 are connected by the flexible circuit board 144. The connection between the first circuit board 131 and the second circuit board 132 is realized through the flexible circuit board 144, making the connection between the first circuit board 131 and the second circuit board 132 relatively simple. In addition, the flexible circuit board 144 has a high degree of deformability, making the installation position of the flexible circuit board 144 more flexible.

[0112] It should be noted that the switch module 100 may be provided with at least one of a flexible circuit board 144, a pin 137, and a first support member 141.

[0113] In some embodiments, referring to Figure 8 , the switch module 100 includes a fan 138. The fan 138 can dissipate heat from the components in the housing 101. An air inlet 115 and an air outlet 116 are provided on the first sub-housing 110 ( Figure 4 ). The fan 138 is disposed at the air inlet 115 of the first sub-housing 110. The fan 138 is disposed close to the air inlet 115. The fan 138 is configured to blow air into the accommodation cavity 102. The fan 138 can drive the air in the external environment to enter the accommodation cavity 102 through the air inlet 115. The temperature of the air brought into the accommodation cavity 102 is relatively low. The air exchanges heat with the components in the accommodation cavity 102, and then the air is discharged from the accommodation cavity 102 through the air outlet 116, thereby realizing heat dissipation of the components.

[0114] Exemplarily, referring to Figure 4 , the air inlet 115 and the air outlet 116 are provided on the opposite side walls of the first sub-housing 110. The air can enter from the air inlet 115 on one side, flow in the housing 101, and then be discharged from the air outlet 116 on the other side. Such a design is conducive to forming a good ventilation path, helping the air to pass through the air inlet 115 and the air outlet 116 faster, improving the air fluidity, and helping to improve the heat dissipation performance.

[0115] Exemplarily, the air inlet 115 can be multiple, and the multiple air inlets 115 can be arranged at intervals.

[0116] Exemplarily, the air outlet 116 can be multiple, and the multiple air outlets 116 can be arranged at intervals.

[0117] In some embodiments, referring to Figure 6, the first circuit board 131 includes a connected first region and a second region. The orthographic projection of the second circuit board 132 on the plane where the first circuit board 131 is located overlaps with the orthographic projection of the first region on the plane where the first circuit board 131 is located. The second circuit board 132 is disposed opposite to the first region along the first direction A. The orthographic projection of the second circuit board 132 on the plane where the first circuit board 131 is located does not overlap with the orthographic projection of the second region on the plane where the first circuit board 131 is located. The second circuit board 132 is offset from the second region along the first direction A. The relay 133 can be disposed on the first region, and the relay 133 is disposed between the first circuit board 131 and the second circuit board 132. The fan 138 can be disposed on the second region. The fan 138 is disposed on the side of the second region facing the second circuit board 132, and the second circuit board 132 does not cover the fan 138, so that the area of the second circuit board 132 is small, which is beneficial to reducing the volume of the housing 101.

[0118] In some embodiments, referring to Figure 6 , the switch module 100 includes a second support member 142. The second support member 142 is configured to support the fan 138. First, the fan 138 is installed on the second support member 142, and then the second support member 142 is installed on the first circuit board 131. In this way, it is beneficial to reduce the installation difficulty of the fan 138 and the first circuit board 131.

[0119] Exemplarily, referring to Figure 9 , on one side of the second support member 142 facing the first circuit board 131 ( Figure 8 ), there is a first insertion member 1421. The first insertion member 1421 penetrates through the first circuit board 131, and the second support member 142 and the first circuit board 131 are connected by an insertion method, which is beneficial to reducing the connection difficulty between the second support member 142 and the first circuit board 131. In addition, the first insertion member 1421 can limit the position of the second support member 142 relative to the first circuit board 131.

[0120] In some embodiments, referring to Figure 9 , on one side of the second support member 142 facing the first circuit board 131 ( Figure 8 ), a second insertion member 1422 and a third insertion member 1423 are spaced apart. There are insertion holes provided on the first circuit board 131, and both the second insertion member 1422 and the third insertion member 1423 are inserted into the insertion holes. The second support member 142 and the first circuit board 131 are connected by an insertion method, which is beneficial to reducing the connection difficulty between the second support member 142 and the first circuit board 131. The second insertion member 1422 and the third insertion member 1423 can limit the position of the second support member 142 relative to the first circuit board 131.

[0121] Exemplarily, referring to Figure 9, both the second insertion member 1422 and the third insertion member 1423 include a connected insertion portion 1423a and a stop portion 1423b. The insertion portion 1423a extends along the first direction A. One end of the insertion portion 1423a along the first direction A is connected to the second support member 142, and a stop portion 1423b is provided at the other end of the insertion portion 1423a along the first direction A. The insertion portion 1423a is inserted into the insertion hole, and the stop portion 1423b is clamped on the side of the first circuit board 131 facing away from the second circuit board 132. The orthographic projection of the stop portion 1423b on the plane where the first circuit board 131 is located is located outside the orthographic projection of the insertion hole on the plane where the first circuit board 131 is located. After the second insertion member 1422 and the third insertion member 1423 are inserted into the insertion hole, the stop portion 1423b can prevent the second insertion member 1422 and the third insertion member 1423 from accidentally coming out of the insertion hole. For example, during the process of inserting the second insertion member 1422 and the third insertion member 1423 into the insertion hole, the insertion portion 1423a can be deformed so that the stop portions 1423b of the second insertion member 1422 and the third insertion member 1423 approach each other to facilitate passing through the insertion hole. When the stop portion 1423b completely passes through the insertion hole, the insertion portion 1423a can return to its initial state, and the stop portions 1423b of the second insertion member 1422 and the third insertion member 1423 move away from each other and are not easily accidentally taken out of the insertion hole.

[0122] In some embodiments, referring to Figure 10 , the switch module 100 includes a mounting member 150. The mounting member 150 is provided on the side of the first sub-housing 110 facing away from the second sub-housing 120, and the mounting member 150 is movably connected to the first sub-housing 110 along the second direction B. The mounting member 150 can move relative to the housing 101 along the second direction B. A first mounting groove 161 is formed between the mounting member 150 and the first sub-housing 110, and the first mounting groove 161 can be used for inserting a member to be mounted. For example, the member to be mounted can be a guide rail 191 ( Figure 3 ).

[0123] Exemplarily, when disassembling the guide rail 191, pushing the mounting member 150 in a direction away from the center of the first sub-housing 110 can cause the mounting member 150 to move away from the guide rail 191, so as to separate the guide rail 191 from the first sub-housing 110 and disassemble the guide rail 191. When installing the guide rail 191, the mounting member 150 can move in a direction approaching the center of the first sub-housing 110 until a part of the mounting member 150 is located on the side of the guide rail 191 facing away from the first sub-housing 110.

[0124] In some embodiments, referring to Figure 11 , the switch module 100 may include a first limiting member 171, and the first limiting member 171 can prevent the mounting member 150 and the first sub-housing 110 from accidentally separating along the second direction B. Continuing to refer to Figure 12, the first limiting member 171 may include a connected first limiting portion 181 and a second limiting portion 182. The first limiting portion 181 is provided on a side of the first sub-shell 110 facing away from the second sub-shell 120, and the first limiting portion 181 is connected to the mounting member 150. The first limiting portion 181 may be elastic. When the mounting member 150 moves along the second direction B under an external force, the first limiting portion 181 may deform along the second direction B. When the external force is removed, the first limiting portion 181 returns to the undeformed state (i.e., the initial state), thereby enabling the mounting member 150 to return to the initial position. The second limiting portion 182 is inserted into the first sub-shell 110. The second limiting portion 182 can prevent the mounting member 150 from accidentally separating from the first sub-shell 110 along the second direction B.

[0125] In some embodiments, referring to Figure 12 , the first limiting portion 181 extends along the third direction C. The first limiting portion 181 has a certain length along the third direction C, which facilitates the first limiting portion 181 to be elastic. One end of the first limiting portion 181 along the third direction C is connected to the mounting member 150, and the other end of the first limiting portion 181 along the third direction C faces the side of the first sub-shell 110 ( Figure 11 ), and the second limiting portion 182 is provided on the first sub-shell 110. There is a limiting hole on the first sub-shell 110, and the second limiting portion 182 is arranged in the limiting hole. Through the cooperation of the second limiting portion 182 and the limiting hole.

[0126] In some embodiments, referring to Figure 11 , the mounting member 150 includes a connected first mounting portion 151 and a second mounting portion 152. The first mounting portion 151 and the second mounting portion 152 may be arranged along the second direction B. A first mounting groove 161 is formed between the first mounting portion 151 and the first sub-shell 110. The second mounting portion 152 includes two first side walls 1521. The two first side walls 1521 are spaced apart along the third direction C. The first side wall 1521 can be used to connect the first limiting member 171. Both of the two first side walls 1521 can be located on the same side of the first mounting portion 151 along the second direction B. The first limiting member 171 can be arranged between the two first side walls 1521, and the first limiting member 171 can be connected to one of the first side walls 1521. For example, the first side wall 1521 can extend along the second direction B, and the structure of the first side wall 1521 is relatively simple, which is beneficial to reducing the manufacturing cost of the mounting member 150.

[0127] In some embodiments, referring to Figure 11The second mounting portion 152 includes a second side wall 1522. The ends of the two first side walls 1521 facing away from the first mounting portion 151 are connected to the second side wall 1522. The second side wall 1522 can extend along the third direction C. The operator can apply external force to the mounting member 150 through the second side wall 1522. In addition, the structure of the second side wall 1522 is relatively simple, which is beneficial to reducing the preparation cost of the mounting member 150.

[0128] In some embodiments, see Figure 11 The second mounting portion 152 may include a third side wall 1523, and one end of the two first side walls 1521 close to the first mounting portion 151 is connected to the first mounting portion 151 through the third side wall 1523. The surface of the third side wall 1523 away from the second side wall 1522 may form the bottom wall of the first mounting groove 161. The third side wall 1523 may prevent the guide rail 191 from shaking along the second direction B. In addition, the structure of the third side wall 1523 is relatively simple, which is conducive to reducing the preparation cost of the mounting member 150.

[0129] In some embodiments, see Figure 11 The first sub-housing 110 may be provided with a second stopper 172, which may prevent the mounting member 150 from moving outward too much under the action of an external force, causing the first stopper 181 to be deformed too much and damaged, and may also prevent the mounting member 150 from accidentally separating from the first sub-housing 110 along the second direction B. The second stopper 172 may include a third stopper 183 and a fourth stopper 184 connected to each other, the third stopper 183 extending along the second direction B, and the third stopper 183 having a certain length along the second direction B, which is conducive to making the third stopper 183 have a certain elasticity, and the third stopper 183 may be deformed, which is conducive to reducing the difficulty of installing the mounting member 150. One end of the third limiting portion 183 along the second direction B is connected to the first sub-shell 110, and the other end of the third limiting portion 183 along the second direction B is provided with a fourth limiting portion 184 on the side away from the second sub-shell 120, and the fourth limiting portion 184 is arranged between the two first side walls 1521, and the fourth limiting portion 184 is arranged on the side of the third side wall 1523 away from the first mounting groove 161. The fourth limiting portion 184 can prevent the mounting member 150 from moving outward too much under the action of external force, causing the first limiting portion 181 to be deformed too much and damaged.

[0130] For example, see Figure 11The distance between the fourth limiting portion 184 and the third side wall 1523 is greater than the dimension of the first mounting groove 161 along the second direction B. The distance between the fourth limiting portion 184 and the third side wall 1523 is the distance that the mounting member 150 can be pushed outward. The distance that the mounting member 150 can be pushed outward is greater than the groove depth of the first mounting groove 161. The distance that the mounting member 150 can be pushed outward is large. When the guide rail 191 is removed, the guide rail 191 can be completely exposed outside the mounting member 150.

[0131] In some embodiments, the number of the first stopper 171 may be at least one. For example, the number of the first stopper 171 may be 1, 2, 3, or any number greater than 3. Figure 11 When there are multiple first position-limiting members 171, the multiple first position-limiting members 171 are arranged at intervals along the second direction B. By providing multiple first position-limiting members 171, the position-limiting reliability of the first position-limiting members 171 can be improved. In addition, even if some of the first position-limiting members 171 are damaged, the other first position-limiting members 171 can still play a position-limiting role.

[0132] In some embodiments, see Figure 12 The surface of the second limiting portion 182 facing away from the first limiting portion 181 is a guide surface 1821. The distance between the guide surface 1821 and the first limiting portion 181 along the first direction A gradually increases from the first mounting portion 151 to the second mounting portion 152, so that the thickness of the second limiting portion 182 close to the first mounting portion 151 is relatively small. During the installation process of the mounting member 150 and the first sub-shell 110, the resistance of the second limiting portion 182 is relatively small, which can reduce the difficulty of assembling the mounting member 150 and the first sub-shell 110. In addition, the thickness of the second limiting portion 182 facing away from the first mounting portion 151 is relatively large, so that the second limiting portion 182 is not easy to escape from the limiting hole, which is beneficial to improving the limiting reliability of the first limiting member 171.

[0133] In some embodiments, see Figure 11 A slide groove 163 is provided on the side of the first sub-housing 110 away from the second sub-housing 120, and the second mounting portion 152 is movably arranged in the slide groove 163 along the second direction B. For example, the first side wall 1521 can be arranged in the slide groove 163, and the first side wall 1521 can move along the second direction B in the slide groove 163, and part of the groove wall of the slide groove 163 is arranged on the side of the first side wall 1521 away from the second sub-housing 120. Two slide grooves 163 can be provided, and the slide grooves 163 are arranged corresponding to the first side wall 1521, and the first side wall 1521 can be arranged in the corresponding slide groove 163.

[0134] In some embodiments, see Figure 4, on a side of the first sub - housing 110 facing away from the second sub - housing 120, a second installation groove 162 is provided. The first installation groove 161 and the second installation groove 162 are opposite and spaced along the second direction B. The first installation groove 161 and the second installation groove 162 are for inserting a component to be installed (for example, the guide rail 191). The first installation groove 161 and the second installation groove 162 can limit both ends of the guide rail 191, so as to facilitate the assembly of the guide rail 191 with the first sub - housing 110.

[0135] Exemplarily, referring to Figure 4 , one end of the guide rail 191 can be first inserted into the second installation groove 162, and then the other end of the guide rail 191 is pressed in the direction close to the first sub - housing 110. The other end of the guide rail 191 pushes the installation part 150 to move outward, and the first limiting part 181 deforms. Until the other end of the guide rail 191 completely passes over the installation part 150, the external force applied to the guide rail 191 is removed, and the first limiting part 181 automatically returns to its initial state and drives the installation part 150 to move inward, so that the first installation part 151 ( Figure 11 ) is located on a side of the guide rail 191 facing away from the first sub - housing 110, and the other end of the guide rail 191 is installed in the first installation groove 161.

[0136] Exemplarily, referring to Figure 11 , the surface of the first installation part 151 on the side facing away from the second installation part 152 can be an inclined surface. The end of the inclined surface close to the first sub - housing 110 is inclined in a direction away from the second installation part 152 relative to the end far from the first sub - housing 110. When installing the guide rail 191, one end of the guide rail 191 can be first inserted into the second installation groove 162, and then the other end of the guide rail 191 is pressed in the direction close to the first sub - housing 110. The other end of the guide rail 191 pushes the installation part 150 to move outward through this inclined surface, making it easier for the guide rail 191 to push the installation part 150.

[0137] In some embodiments, referring to Figure 8 , the first sub - housing 110 includes a first sub - part 111 and a second sub - part 112. The first sub - part 111 and the second sub - part 112 are detachably connected, making the assembly between the first sub - part 111 and the second sub - part 112 convenient and reliable. The second sub - part 112 is provided on a side of the first sub - part 111 facing away from the second sub - housing 120. By disassembling the second sub - part 112, the devices in the accommodation cavity 102 can be maintained. In addition, the second sub - part 112 can support the devices in the accommodation cavity 102.

[0138] Exemplarily, referring to Figure 8, on one side of the second sub - part 112 facing the second sub - housing 120, there is a bearing part 113. The bearing part 113 is used to support the first circuit board 131. The bearing part 113 is arranged at the edge of the second sub - part 112, and the first circuit board 131 is in contact with the surface of the bearing part 113 facing the second sub - housing 120.

[0139] In some embodiments, referring to Figure 8 , a heat - conducting pad 139 can be arranged between the second sub - part 112 and the first circuit board 131, and the bearing part 113 can be arranged on the outer periphery of the heat - conducting pad 139.

[0140] In some embodiments, referring to Figure 8 , on one side of the second sub - part 112 facing the second sub - housing 120, there are a fifth limiting part 185 and a sixth limiting part 186. The fifth limiting part 185 and the sixth limiting part 186 are arranged on opposite sides of the first circuit board 131, and the fifth limiting part 185 and the sixth limiting part 186 can play a role in limiting the first circuit board 131.

[0141] Exemplarily, the fifth limiting part 185 and the sixth limiting part 186 can be arranged on both sides of the first circuit board 131 along the second direction B. The fifth limiting part 185 can be at least one. When there are multiple fifth limiting parts 185, the multiple fifth limiting parts 185 can be arranged at intervals along the third direction C, and the multiple fifth limiting parts 185 are arranged on the same side of the first circuit board 131 along the second direction B. The sixth limiting part 186 can be at least one. When there are multiple sixth limiting parts 186, the multiple sixth limiting parts 186 can be arranged at intervals along the third direction C, and the multiple sixth limiting parts 186 are arranged on the other side of the first circuit board 131 along the second direction B.

[0142] In some embodiments, referring to Figure 8 , on one side of the second sub - part 112 facing the second sub - housing 120, there is a positioning part 174. The positioning part 174 penetrates through the first circuit board 131, and the positioning part 174 can play a role in positioning the first circuit board 131, improving the connection reliability between the first circuit board 131 and the first sub - housing 110.

[0143] In some embodiments, referring to Figure 8, a third limiting member 173 is provided on one side of the first sub - part 111 facing away from the second sub - housing 120. The outer side of the second sub - part 112 is arranged in a limiting groove 114. The limiting groove 114 is arranged on the circumferential side wall of the second sub - part 112. The third limiting member 173 includes a connected seventh limiting part 187 and an eighth limiting part 188. The seventh limiting part 187 extends along the first direction A. The seventh limiting part 187 has a certain length along the first direction A, which is beneficial for the seventh limiting part 187 to have elasticity. The seventh limiting part 187 is arranged in the limiting groove 114. The limiting groove 114 can prevent the seventh limiting part 187 from moving circumferentially along the first sub - housing 110. One end of the seventh limiting part 187 along the first direction A is connected to the first sub - part 111, and an eighth limiting part 188 is provided at the other end of the seventh limiting part 187 along the first direction A. The eighth limiting part 188 abuts against the side of the second sub - part 112 facing away from the second sub - housing 120. The eighth limiting part 188 can prevent the separation between the second sub - part 112 and the first sub - part 111 along the first direction A. By providing the third limiting member 173, the detachable connection between the first sub - part 111 and the second sub - part 112 can be realized.

[0144] Exemplarily, there can be multiple third limiting members 173, and the multiple third limiting members 173 can be arranged at intervals along the circumference of the first sub - housing 110.

[0145] In some embodiments, referring to Figure 4 , the switch module 100 can include a first terminal 1921. The first terminal 1921 is arranged in the accommodation cavity 102. The first terminal 1921 can be connected to at least one of the first circuit board 131 and the second circuit board 132. In addition, the first terminal 1921 is used to connect to an external circuit.

[0146] In some embodiments, referring to Figure 2a , a first wiring hole 1221 and a second wiring hole 1222 are provided on the housing 101. The first wiring hole 1221 can be used for a cable to pass through. The cable is connected to the first terminal 1921 through the first wiring hole 1221. A fastener for fixing the cable is provided on the first terminal 1921. The fastener can be operated through the second wiring hole 1222 to fix the cable to the first terminal 1921. The first wiring hole 1221 is arranged on the side wall of the first sub - housing, and the second wiring hole 1222 is arranged on the wall of the first sub - housing facing the second sub - housing. The first wiring hole 1221 can be at least one, and the second wiring hole 1222 can be at least one. Among them, the cable is used to connect the external circuit and the first terminal 1921.

[0147] In some examples, referring to Figure 2a, There is one first wiring hole 1221, and the number of the first wiring holes 1221 is small. There is one second wiring hole 1222, and the number of the second wiring holes 1222 is small, which can reduce the setting difficulty.

[0148] In some other examples, refer to Figure 2b , the first wiring hole 1221 includes a plurality of first sub-wiring holes 1221a arranged at intervals, and there is an interval between two adjacent first sub-wiring holes 1221a. The second wiring hole 1222 includes a plurality of second sub-wiring holes 1222a arranged at intervals, and there is an interval between two adjacent second sub-wiring holes 1222a. The number of both the first sub-wiring holes 1221a and the second sub-wiring holes 1222a is plural, and the first sub-wiring holes 1221a and the second sub-wiring holes 1222a are arranged in one-to-one correspondence. A cable is threaded through one first sub-wiring hole 1221a and operates the fastener through the corresponding second sub-wiring hole 1222a. In this way, by arranging both the first sub-wiring holes 1221a and the second sub-wiring holes 1222a at intervals, the sizes of the first sub-wiring holes 1221a and the second sub-wiring holes 1222a can be reduced, which is beneficial to preventing foreign objects from falling into the electronic device 10 through the first sub-wiring holes 1221a and the second sub-wiring holes 1222a.

[0149] In some embodiments, the circuit breaker 220 may include a second terminal and the circuit breaker 220 body. The second terminal is connected to the circuit breaker 220 body, and the second terminal is used to connect to an external circuit.

[0150] The following describes the electronic device 10 provided by the embodiments of the present application.

[0151] Refer to Figure 15 , the embodiments of the present application provide an electronic device 10. The electronic device 10 may include a box body 210 and the switch module 100 in the above embodiments. At least part of the switch module 100 is arranged in the box body 210. The box body 210 can protect the switch module 100. The electronic device 10 includes a circuit breaker 220. When the current in the circuit exceeds the rated current of the circuit breaker 220, the circuit breaker 220 can automatically cut off the circuit. Both the circuit breaker 220 and the switch module 100 are arranged in the box body 210, and the circuit breaker 220 is arranged outside the housing 101. The circuit breaker 220 and the switch module 100 can be arranged along the third direction C.

[0152] Exemplarily, the number of the switch modules 100 can be at least one. When the number of the switch modules 100 is plural, the plural switch modules 100 can be arranged along the third direction C.

[0153] Exemplarily, the number of the circuit breakers 220 can be at least one. When the number of the circuit breakers 220 is plural, the plural circuit breakers 220 can be arranged along the third direction C.

[0154] In some embodiments, referring to Figure 15 , the electronic device 10 includes a guide rail 191 disposed in the box body 210, and the guide rail 191 can extend along the third direction C. At this time, the circuit breaker 220 and the switch module 100 are arranged along the extending direction of the guide rail 191, and both the circuit breaker 220 and the switch module 100 can be connected to the guide rail 191.

[0155] In some embodiments, referring to Figure 16 , the circuit breaker 220 may include a first circuit breaker part 221 and a second circuit breaker part 222 connected to each other, and the first circuit breaker part 221 and the second circuit breaker part 222 may be arranged along the direction from the first sub-shell 110 to the second sub-shell 120. The dimension L3 of the second circuit breaker part 222 along the second direction B is smaller than the dimension L4 of the first circuit breaker part 221 along the second direction B, that is, the dimension L3 of the second circuit breaker part 222 along the second direction B is set to be smaller, and the dimension L4 of the first circuit breaker part 221 along the second direction B is set to be larger.

[0156] In this way, by setting the dimension of the second circuit breaker part 222 along the second direction B to be smaller, when the circuit breaker 220 and the switch module 100 are installed in the box body 210, it is beneficial to avoid interference between the second circuit breaker part 222 and the second sub-shell 120. In addition, by setting the dimension of the first circuit breaker part 221 along the second direction B to be larger, the components of the circuit breaker 220 are more concentrated in the first circuit breaker part 221. The larger-sized first circuit breaker part 221 can provide better support for the components, can share the weight of the components better, and can avoid excessive local pressure on the first circuit breaker part 221.

[0157] In some embodiments, referring to Figure 14 , an opening 2111 is formed on the box wall of the box body 210, and both the second circuit breaker part 222 and the second sub-shell 120 can be exposed outside the opening 2111 to facilitate the operation of the switch module 100. The dimension of the second circuit breaker part 222 along the second direction B is equal to the dimension of the second sub-shell 120 along the second direction B. The overall structure formed by the second circuit breaker part 222 and the second sub-shell 120 has substantially the same dimension along the second direction B. The shape of this overall structure is relatively simple, and the volume of this overall structure is small, which is beneficial to saving the space inside the box body 210. In addition, it enables the opening 2111 to be compatible with the second circuit breaker parts 222 of all circuit breakers 220 and the second sub-shells 120 of all switch modules 100.

[0158] Among them, the same dimension in the embodiments of the present application may mean substantially the same dimension.

[0159] Exemplarily, the opening 2111 may be a strip-shaped opening 2111, and the opening 2111 may extend along the third direction C, so that the shape of the opening 2111 is relatively simple.

[0160] In some embodiments, referring to Figure 14 , the box body 210 may include a first box wall 211. The first box wall 211 may be the box wall on one side of the box body 210 along the first direction. The first box wall 211 covers the circuit breaker 220 and the switch module 100, and the opening 2111 may be provided on the first box wall 211. The box body 210 may be provided with a receiving space 212 ( Figure 15 ), at least part of the circuit breaker 220 and at least part of the switch module are arranged in the receiving space 212. The opening 2111 communicates with the receiving space 212.

[0161] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0162] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
