Detailed Implementation

[0077] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0078] In the description of this application, it should be understood that if 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" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0079] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0080] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0081] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0082] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening 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 intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0083] In related technologies, a switch module may include a housing, a circuit board, and a relay, with the relay electrically connected to the circuit board, and both the circuit board and the relay may be housed within the housing.

[0084] However, since the relays and other components of the switching module are all located on the same circuit board, the circuit board area is large, which in turn makes the housing volume large, and thus the switching module volume large.

[0085] To address the aforementioned issues, embodiments of this application provide a switch module and an electronic device that can reduce the size of the switch module.

[0086] The following description, in conjunction with Figures 1-16, will illustrate the switch module 100 and electronic device 10 provided in the embodiments of this application.

[0087] Referring to Figure 1, this embodiment of the application provides a switch module 100, which includes a housing 101, a first circuit board 131, and a second circuit board 132. The housing 101 may have a receiving cavity 102. Both the first circuit board 131 and the second circuit board 132 may 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 to realize signal transmission between the first circuit board 131 and the second circuit board 132. The spaced-apart arrangement of the first circuit board 131 and the second circuit board 132 along the first direction A means that there is a gap between the first circuit board 131 and the second circuit board 132 along the first direction A.

[0088] The switch module 100 includes a relay 133, which is disposed between a first circuit board 131 and a second circuit board 132, and 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 using 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 simultaneously.

[0089] Thus, by setting two circuit boards (first circuit board 131 and second circuit board 132), different devices in the accommodating cavity 102 can be distributed on the first circuit board 131 and the second circuit board 132. By stacking the first circuit board 131 and the second circuit board 132 along the first direction A, the total area of ​​the first circuit board 131 and the second circuit board 132 can be reduced, which is beneficial to reducing the volume of the housing 101 and thus reducing the volume of the switch module 100.

[0090] Referring to Figure 4, the housing 101 includes a first sub-housing 110 and a second sub-housing 120 connected together, and the first sub-housing 110 and the second sub-housing 120 can be arranged along a 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.

[0091] Thus, by setting the dimension of the second sub-shell 120 along the second direction B to be smaller, it is beneficial to avoid interference between the second sub-shell 120 and other structures within the housing 210 when the housing 101 is installed with the enclosure 210. Conversely, by setting the dimension of the first sub-shell 110 along the second direction B to be larger, the first sub-shell 110 has a larger volume, allowing it to accommodate more components. This results in a more concentrated arrangement of components within the housing 101. The larger volume of the first sub-shell 110 provides better support for each component, effectively distributing the weight of the components and preventing excessive local pressure on the first sub-shell 110.

[0092] For example, referring to Figure 2a, the switch module 100 may have a first direction A, a second direction B, and a third direction C, where 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 may be perpendicular to each other. For example, the first direction A may be the height direction of the switch module 100, the second direction B may be the width direction of the switch module 100, and the third direction C may be the length direction of the switch module 100. The length, width, and height, etc., in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width may be greater than, equal to, or less than the length.

[0093] In some embodiments, referring to FIG4, the 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 disposed in the receiving cavity 102 of the first sub-housing 110. This is because the relay 133 and the first circuit board are generally relatively large, and they are concentrated in a larger receiving cavity 102 of the first sub-housing 110, which helps to reduce the volume of the housing 101.

[0094] The second circuit board 132 is projected onto the plane of the first circuit board 131. The first circuit board 131 is located within the projection of the first circuit board 131 onto the plane of the first circuit board 131. 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 opposite each other along the thickness direction, which helps to reduce the total area occupied by the first circuit board 131 and the second circuit board 132, and helps to reduce the volume of the housing 101.

[0095] In some embodiments, referring to Figure 5, the orthographic projection of the relay 133 on the plane where the first circuit board 131 is located is 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 to each other, which helps to reduce the total area occupied by the second circuit board 132 and the relay 133, and helps to reduce the volume of the housing 101.

[0096] In other embodiments, the orthographic projection of the relay 133 on the plane of the first circuit board 131 does not overlap with the orthographic projection of the second circuit board 132 on the plane of the first circuit board 131 at least partially. The second circuit board 132 partially covers the relay 133. Alternatively, the side 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. This arrangement ensures that at least a portion of the second circuit board 132 is far from the relay 133, which can reduce the adverse effects of the heat from the relay 133 on the devices on the second circuit board 132.

[0097] 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 mounted on one of the first circuit board 131 and the second circuit board 132. The other circuit board 131 and the second circuit board 132 are provided with a control circuit, which is electrically connected to the relay 133 and 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 the control circuit or the relay 133 malfunctions, the faulty circuit board can be replaced individually without replacing both circuit boards, which helps to reduce maintenance costs.

[0098] In the embodiment where the 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. Setting the smaller control circuit on the second circuit board 132 is beneficial to reducing the overall volume of the second circuit board 132 and the control circuit, and also beneficial to reducing the volume of the housing 101.

[0099] In some embodiments, referring to FIG4, a first type device 134 is provided on the second circuit board 132. For example, the first type device 134 is provided on the side of the second circuit board 132 facing the first circuit board 131, and the first type device 134 is provided on the side of the second circuit board 132 away from the first housing wall 121. There is no need to reserve space for the first type device 134 between the second circuit board 132 and the first housing wall 121, so that the distance between the second circuit board 132 and the first housing wall 121 along the first direction A is smaller, the button 135 (FIG. 6) on the second circuit board 132 is closer to the first housing wall 121, the length of the operating component is shorter, and it is easier to press the button 135.

[0100] In other embodiments, the first type device 134 can be disposed on the side of the second circuit board 132 away from the first circuit board 131. The first type device 134 is disposed on the side of the second circuit board 132 away from the relay 133. The relay 133 and the first type device 134 are respectively disposed on the two sides of the second circuit board 132. This can make the first type device 134 farther away from the relay 133, which can reduce the adverse effects of the heat of the relay 133 on the first type device 134.

[0101] In some embodiments, a second type of device may be provided on the second circuit board 132, and 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 larger or smaller than that of the second type of device. And / or, the thermal sensitivity of the first type of device and the second type of device may be different. For example, the first type of device 134 may be more sensitive to heat.

[0102] For example, the first type device 134 includes a heat-sensitive device. When the first type device 134 is disposed on the side of the second circuit board 132 away from the first circuit board 131, the adverse effects of the heat from the relay 133 on the heat-sensitive device can be reduced.

[0103] In some embodiments, referring to Figure 6, a button 135 is provided on the second circuit board 132. The button 135 is located on the side of the second circuit board 132 opposite to the first circuit board 131. The switch module 100 includes an operating member connected to the button 135. By pressing the operating member, the button 135 can be pressed, thereby controlling the operation of the devices inside the housing 101. The second sub-housing 120 includes a first housing wall 121 (Figure 4). The first housing wall 121 is located at the end of the second sub-housing 120 opposite to the first sub-housing 110. An operating part is provided on the first housing wall 121, which is connected to the operating member. The operating part can be arranged opposite to the operating member along a first direction A. The end of the operating member away from the operating part is connected to the button 135. By pressing the operating part, it is convenient for the operator to press the operating member. For example, the operating part can have a certain elasticity. When the operating part is pressed, the operating part can deform and drive the operating member to press the button 135.

[0104] It should be noted that the operating unit can be indirectly connected to the button 135. For example, the operating unit can be connected to the button 135 through an operating component, thus allowing for more flexible placement of the operating unit and the button 135. Alternatively, the operating unit can be directly connected to the button 135 without the need for other structures to connect the operating unit and the button 135, which simplifies the structure of the switch module 100 and reduces manufacturing costs.

[0105] For example, the operating part can extend in a direction parallel to the first circuit board 131, and the operating part has a certain length in the direction parallel to the first circuit board 131, so as to make the operating part flexible.

[0106] In some embodiments, referring to FIG6, a light-emitting element 140 is provided on the second circuit board 132, and the light-emitting element 140 is located on the side of the second circuit board 132 opposite to the first circuit board 131. For example, the light-emitting element 140 can be an LED lamp. A light guide post 136 is provided on the side of the light-emitting element 140 opposite to the second circuit board 132. Since the light-emitting element 140 is far from the surface of the housing 101, the light emitted by the light-emitting element 140 can be conducted to the surface of the housing 101 through the light guide post 136.

[0107] In some embodiments, referring to FIG7, 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 through 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 high, which is beneficial to improving the connection stability between the first circuit board 131 and the second circuit board 132.

[0108] Wherein, 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, which may 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.

[0109] For example, the number of 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 gap between two adjacent first support members 141.

[0110] In some embodiments, referring to FIG6, 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 through 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 provide a certain support for the second circuit board 132, which can improve the connection reliability between the first circuit board 131 and the second circuit board 132.

[0111] In embodiments where both the pin 137 and the first support member 141 are provided, the pin 137 and the first support member 141 may be provided at intervals. The interval between the pin 137 and the first support member 141 means that there is a gap between the pin 137 and the first support member 141.

[0112] In some embodiments, referring to FIG13, the switch module 100 includes a flexible strip 144, and the first circuit board 131 and the second circuit board 132 are connected through the flexible strip 144. The connection between the first circuit board 131 and the second circuit board 132 is realized through the flexible strip 144, making the connection between the first circuit board 131 and the second circuit board 132 relatively simple. In addition, the flexible strip 144 has a high degree of deformability, making the setting position of the flexible strip 144 more flexible.

[0113] It should be noted that the switch module 100 may be provided with at least one of a flexible strip 144, a pin 137, and a first support member 141.

[0114] In some embodiments, referring to FIG8, the switch module 100 includes a fan 138, which can dissipate heat from the devices inside the housing 101. The first sub-housing 110 is provided with an air inlet 115 and an air outlet 116 (FIG. 4). The fan 138 is located at the air inlet 115 of the first sub-housing 110. The fan 138 is positioned close to the air inlet 115 and is configured to blow air into the accommodating cavity 102. The fan 138 can drive air from the outside environment into the accommodating cavity 102 through the air inlet 115. The air brought into the accommodating cavity 102 has a lower temperature and exchanges heat with the devices inside the accommodating cavity 102. The air is then discharged from the accommodating cavity 102 through the air outlet 116, thereby achieving heat dissipation for the devices.

[0115] For example, referring to Figure 4, the air inlet 115 and the air outlet 116 are disposed on opposite sidewalls of the first sub-housing 110. Air can enter from the air inlet 115 on one side, flow inside the housing 101, and then be discharged from the air outlet 116 on the other side. This design is conducive to forming a good ventilation path, which helps the air to pass through the air inlet 115 and the air outlet 116 more quickly, improves the air flow, and helps to improve the heat dissipation performance.

[0116] For example, there can be multiple air inlets 115, and the multiple air inlets 115 can be set at intervals.

[0117] For example, there can be multiple air outlets 116, and the multiple air outlets 116 can be set at intervals.

[0118] In some embodiments, referring to FIG6, the first circuit board 131 includes a first region and a second region connected together. The orthographic projection of the second circuit board 132 on the plane of the first circuit board 131 overlaps with the orthographic projection of the first region on the plane of the first circuit board 131. The second circuit board 132 and the first region are disposed opposite to each other along a first direction A. The orthographic projection of the second circuit board 132 on the plane of the first circuit board 131 does not overlap with the orthographic projection of the second region on the plane of the first circuit board 131. The second circuit board 132 and the second region are offset along the first direction A. A relay 133 may be disposed on the first region, between the first circuit board 131 and the second circuit board 132. A fan 138 may be disposed on the second region, on the side of the second region facing the second circuit board 132. The second circuit board 132 does not cover the fan 138, making the area of ​​the second circuit board 132 smaller, which is beneficial to reducing the volume of the housing 101.

[0119] In some embodiments, referring to FIG6, the switch module 100 includes a second support member 142, which is configured to support a fan 138. The fan 138 is first installed on the second support member 142, and then the second support member 142 is installed on the first circuit board 131. This helps to reduce the installation difficulty of the fan 138 and the first circuit board 131.

[0120] For example, referring to Figure 9, the second support member 142 is provided with a first insertion member 1421 on the side facing the first circuit board 131 (Figure 8). The first insertion member 1421 passes through the first circuit board 131 and connects the second support member 142 and the first circuit board 131 by insertion, which helps to reduce 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.

[0121] In some embodiments, referring to FIG9, the second support member 142 is provided with a second insertion member 1422 and a third insertion member 1423 spaced apart on the side facing the first circuit board 131 (FIG8). The first circuit board 131 is provided with a socket, and the second insertion member 1422 and the third insertion member 1423 are both inserted into the socket. The second support member 142 and the first circuit board 131 are connected by insertion, which helps to reduce 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.

[0122] For example, referring to FIG9, 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 a first direction A, and one end of the insertion portion 1423a along the first direction A is connected to the second support member 142. The other end of the insertion portion 1423a along the first direction A is provided with the stop portion 1423b. The insertion portion 1423a passes through the socket, and the stop portion 1423b is engaged on the side of the first circuit board 131 opposite to the second circuit board 132. The orthographic projection of the stop portion 1423b on the plane of the first circuit board 131 is located outside the orthographic projection of the socket on the plane of the first circuit board 131. After the second insertion member 1422 and the third insertion member 1423 are inserted into the socket, the stop portion 1423b can prevent the second insertion member 1422 and the third insertion member 1423 from accidentally dislodging from the socket. For example, during the insertion of the second insert 1422 and the third insert 1423 into the socket, the insert portion 1423a can deform, causing the stop portions 1423b of the second insert 1422 and the third insert 1423 to move closer to each other and pass through the socket. After the stop portions 1423b have completely passed through the socket, the insert portion 1423a can return to its initial state, and the stop portions 1423b of the second insert 1422 and the third insert 1423 will move further apart and will not easily come out of the socket accidentally.

[0123] In some embodiments, referring to FIG10, the switch module 100 includes a mounting member 150, which is disposed on the side of the first sub-housing 110 opposite to the second sub-housing 120, and is movably connected to the first sub-housing 110 along a 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, which can be used for inserting a component to be mounted. For example, the component to be mounted can be a guide rail 191 (FIG. 3).

[0124] For example, when disassembling the guide rail 191, pushing the mounting member 150 away from the center of the first sub-housing 110 can move the mounting member 150 away from the guide rail 191, thereby facilitating the separation of the guide rail 191 from the first sub-housing 110 and the removal of the guide rail 191. When installing the guide rail 191, the mounting member 150 can move towards the center of the first sub-housing 110 until a portion of the mounting member 150 is located on the side of the guide rail 191 facing away from the first sub-housing 110.

[0125] In some embodiments, referring to FIG11, the switch module 100 may include a first limiting member 171, which prevents the mounting member 150 from accidentally separating from the first sub-housing 110 along the second direction B. Referring further to FIG12, the first limiting member 171 may include a first limiting portion 181 and a second limiting portion 182 connected together. The first limiting portion 181 is located on the side of the first sub-housing 110 opposite to the second sub-housing 120 and 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 the action of 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 its undeformed state (i.e., the initial state), thereby allowing the mounting member 150 to return to its initial position. The second limiting portion 182 is inserted into the first sub-housing 110. The second limiting part 182 can prevent the mounting part 150 from accidentally separating from the first sub-housing 110 along the second direction B.

[0126] In some embodiments, referring to FIG12, the first limiting portion 181 extends along a third direction C and has a certain length along the third direction C to facilitate the elasticity of the first limiting portion 181. 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 is provided with a second limiting portion 182 on the side facing the first sub-housing 110 (FIG. 11). The first sub-housing 110 is provided with a limiting hole, and the second limiting portion 182 is disposed in the limiting hole. The second limiting portion 182 and the limiting hole are engaged.

[0127] In some embodiments, referring to FIG11, the mounting member 150 includes a first mounting portion 151 and a second mounting portion 152 connected together. The first mounting portion 151 and the second mounting portion 152 can be arranged along a second direction B. A first mounting groove 161 is formed between the first mounting portion 151 and the first sub-housing 110. The second mounting portion 152 includes two first sidewalls 1521, which are spaced apart along a third direction C. The first sidewalls 1521 can be used to connect to a first limiting member 171. Both first sidewalls 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 disposed between the two first sidewalls 1521 and can be connected to one of the first sidewalls 1521. For example, the first sidewall 1521 can extend along the second direction B. The structure of the first sidewall 1521 is relatively simple, which helps to reduce the manufacturing cost of the mounting member 150.

[0128] In some embodiments, referring to FIG11, the second mounting portion 152 includes a second sidewall 1522. The ends of the two first sidewalls 1521 that are away from the first mounting portion 151 are connected to the second sidewall 1522. The second sidewall 1522 can extend along a third direction C. The operator can apply external force to the mounting component 150 through the second sidewall 1522. In addition, the structure of the second sidewall 1522 is relatively simple, which helps to reduce the manufacturing cost of the mounting component 150.

[0129] In some embodiments, referring to FIG11, the second mounting portion 152 may include a third sidewall 1523. The ends of the two first sidewalls 1521 near the first mounting portion 151 are connected to the first mounting portion 151 through the third sidewall 1523. The surface of the third sidewall 1523 facing away from the second sidewall 1522 can form the bottom wall of the first mounting groove 161. By providing the third sidewall 1523, the guide rail 191 can be prevented from shaking along the second direction B. In addition, the structure of the third sidewall 1523 is relatively simple, which helps to reduce the manufacturing cost of the mounting component 150.

[0130] In some embodiments, referring to FIG11, a second limiting member 172 may be provided on the first sub-housing 110. The second limiting member 172 can prevent the mounting member 150 from moving outward too much under the action of external force, causing excessive deformation of the first limiting part 181 and damage. It can also prevent the mounting member 150 from accidentally separating from the first sub-housing 110 along the second direction B. The second limiting member 172 may include a connected third limiting part 183 and a fourth limiting part 184. The third limiting part 183 extends along the second direction B and has a certain length along the second direction B, which is beneficial to give the third limiting part 183 a certain elasticity. The third limiting part 183 can deform, which helps to reduce the installation difficulty of the mounting member 150. One end of the third limiting part 183 along the second direction B is connected to the first sub-shell 110. The other end of the third limiting part 183 along the second direction B is provided with a fourth limiting part 184 on the side away from the second sub-shell 120. The fourth limiting part 184 is located between the two first side walls 1521. The fourth limiting part 184 is located on the side of the third side wall 1523 away from the first mounting groove 161. The fourth limiting part 184 can prevent the mounting part 150 from moving outward too much under the action of external force, which would cause the first limiting part 181 to deform too much and be damaged.

[0131] For example, referring to FIG11, the distance between the fourth limiting part 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 part 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 mounting member 150 can be pushed outward a large distance, so that when the guide rail 191 is disassembled, the guide rail 191 can be completely exposed outside the mounting member 150.

[0132] In some embodiments, the number of first limiting members 171 can be at least one. For example, the number of first limiting members 171 can be any number of one, two, three, or more than three. Referring to Figure 11, when there are multiple first limiting members 171, the multiple first limiting members 171 are spaced apart along the second direction B. By setting multiple first limiting members 171, the limiting reliability of the first limiting members 171 can be improved. In addition, even if some of the first limiting members 171 are damaged, the other part of the first limiting members 171 can still play a limiting role.

[0133] In some embodiments, referring to FIG12, the side of the second limiting part 182 facing away from the first limiting part 181 is a guide surface 1821. The distance between the guide surface 1821 and the first limiting part 181 along the first direction A gradually increases from the first mounting part 151 to the second mounting part 152, making the thickness of the second limiting part 182 near the first mounting part 151 smaller. During the installation of the mounting part 150 and the first sub-housing 110, the resistance of the second limiting part 182 is smaller, which can reduce the assembly difficulty of the mounting part 150 and the first sub-housing 110. In addition, it also makes the thickness of the second limiting part 182 facing away from the first mounting part 151 larger, making the second limiting part 182 less likely to come out of the limiting hole, which is beneficial to improving the limiting reliability of the first limiting part 171.

[0134] In some embodiments, referring to FIG11, a groove 163 is provided on the side of the first sub-housing 110 opposite to the second sub-housing 120. The second mounting part 152 is movably disposed in the groove 163 along the second direction B. For example, a first sidewall 1521 can be disposed in the groove 163 and can move along the second direction B in the groove 163. A portion of the groove wall of the groove 163 is disposed on the side of the first sidewall 1521 opposite to the second sub-housing 120. Two grooves 163 can be provided, with each groove 163 corresponding to a first sidewall 1521, and the first sidewall 1521 can be disposed in the corresponding groove 163.

[0135] In some embodiments, referring to FIG4, the first sub-housing 110 has a second mounting groove 162 on the side opposite to the second sub-housing 120. The first mounting groove 161 and the second mounting groove 162 are arranged opposite to each other and spaced apart along the second direction B. The first mounting groove 161 and the second mounting groove 162 are used for inserting the component to be installed (e.g., guide rail 191). The first mounting groove 161 and the second mounting groove 162 can limit the two ends of the guide rail 191 to facilitate the assembly of the guide rail 191 with the first sub-housing 110.

[0136] For example, referring to Figure 4, one end of the guide rail 191 can be inserted into the second mounting groove 162 first, and then the other end of the guide rail 191 can be pressed towards the first sub-housing 110. The other end of the guide rail 191 pushes the mounting member 150 outward, and the first limiting part 181 deforms until the other end of the guide rail 191 completely passes the mounting member 150. After that, 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 mounting member 150 to move inward, so that the first mounting part 151 (Figure 11) is located on the side of the guide rail 191 away from the first sub-housing 110, and the other end of the guide rail 191 is installed in the first mounting groove 161.

[0137] For example, referring to Figure 11, the side of the first mounting part 151 facing away from the second mounting part 152 can be inclined. The end of the inclined surface near the first sub-housing 110 is inclined in the direction away from the second mounting part 152 relative to the end away from the first sub-housing 110. When installing the guide rail 191, one end of the guide rail 191 can be inserted into the second mounting groove 162 first, and then the other end of the guide rail 191 can be pressed in the direction close to the first sub-housing 110. The other end of the guide rail 191 pushes the mounting member 150 outward through the inclined surface, making it easier for the guide rail 191 to push the mounting member 150.

[0138] In some embodiments, referring to FIG8, the first sub-housing 110 includes a first sub-part 111 and a second sub-part 112, which are detachably connected, making assembly between the first sub-part 111 and the second sub-part 112 convenient and reliable. The second sub-part 112 is located on the side of the first sub-part 111 opposite to the second sub-housing 120. The device inside the receiving cavity 102 can be maintained by disassembling the second sub-part 112. In addition, the second sub-part 112 can provide support for the device inside the receiving cavity 102.

[0139] For example, referring to FIG8, the second sub-part 112 is provided with a support part 113 on the side facing the second sub-housing 120. The support part 113 is used to support the first circuit board 131. The support part 113 is disposed at the edge of the second sub-part 112, and the first circuit board 131 is in contact with the surface of the support part 113 facing the second sub-housing 120.

[0140] In some embodiments, referring to FIG8, a thermal pad 139 may be provided between the second sub-part 112 and the first circuit board 131, and the carrier part 113 may be provided on the outer periphery of the thermal pad 139.

[0141] In some embodiments, referring to FIG8, the second sub-part 112 is provided with a fifth limiting part 185 and a sixth limiting part 186 on the side facing the second sub-housing 120. The fifth limiting part 185 and the sixth limiting part 186 are provided on opposite sides of the first circuit board 131, and the fifth limiting part 185 and the sixth limiting part 186 can limit the first circuit board 131.

[0142] For example, the fifth limiting portion 185 and the sixth limiting portion 186 can be disposed on both sides of the first circuit board 131 along the second direction B. There can be at least one fifth limiting portion 185. When there are multiple fifth limiting portions 185, they can be spaced apart along the third direction C, and the multiple fifth limiting portions 185 are disposed on the same side of the first circuit board 131 along the second direction B. There can be at least one sixth limiting portion 186. When there are multiple sixth limiting portions 186, they can be spaced apart along the third direction C, and the multiple sixth limiting portions 186 are disposed on the other side of the first circuit board 131 along the second direction B.

[0143] In some embodiments, referring to FIG8, the second sub-part 112 is provided with a positioning member 174 on the side facing the second sub-housing 120. The positioning member 174 passes through the first circuit board 131 and can position the first circuit board 131, thereby improving the connection reliability between the first circuit board 131 and the first sub-housing 110.

[0144] In some embodiments, referring to FIG8, a third limiting member 173 is provided on the side of the first sub-part 111 away from the second sub-shell 120. A limiting groove 114 is provided on the outer side of the second sub-part 112, and the limiting groove 114 is provided on the circumferential sidewall 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 and 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 disposed in the limiting groove 114, which prevents 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 the other end of the seventh limiting part 187 along the first direction A is provided with an eighth limiting part 188. The eighth limiting part 188 abuts against the side of the second sub-part 112 away from the second sub-housing 120, and prevents the second sub-part 112 and the first sub-part 111 from separating along the first direction A. By providing the third limiting member 173, a detachable connection between the first sub-part 111 and the second sub-part 112 can be achieved.

[0145] For example, there may be multiple third limiting members 173, and the multiple third limiting members 173 may be arranged at intervals along the circumference of the first sub-housing 110.

[0146] In some embodiments, referring to FIG4, the switch module 100 may include a first terminal 1921 disposed in the receiving cavity 102. The first terminal 1921 may 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 for connection to external circuitry.

[0147] In some embodiments, referring to FIG2a, the housing 101 is provided with a first wiring hole 1221 and a second wiring hole 1222. The first wiring hole 1221 is used for cable passage, and the cable is connected to the first terminal 1921 through the first wiring hole 1221. The first terminal 1921 is provided with a fastener for fixing the cable, and 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 provided on the side wall of the first sub-housing, and the second wiring hole 1222 is provided on the shell wall of the first sub-housing facing the second sub-housing. There can be at least one first wiring hole 1221 and at least one second wiring hole 1222. The cable is used to connect an external circuit and the first terminal 1921.

[0148] In some examples, see Figure 2a, there is only one first wiring hole 1221, and the number of first wiring holes 1221 is relatively small. There is also only one second wiring hole 1222, and the number of second wiring holes 1222 is relatively small, which can reduce the difficulty of setting up.

[0149] In other examples, referring to Figure 2b, the first wiring hole 1221 includes a plurality of first sub-wiring holes 1221a spaced apart, with indirect connections between adjacent first sub-wiring holes 1221a. Similarly, the second wiring hole 1222 includes a plurality of second sub-wiring holes 1222a spaced apart, with indirect connections between adjacent second sub-wiring holes 1222a. Both the first and second sub-wiring holes 1221a and 1222a are multiple in number and are arranged in a one-to-one correspondence. A cable passes through one first sub-wiring hole 1221a and operates the fastener through the corresponding second sub-wiring hole 1222a. Thus, by spaced out the first and second sub-wiring holes 1221a and 1222a, their size can be reduced, which helps prevent foreign objects from falling into the electronic device 10 through the first and second sub-wiring holes 1221a and 1222a.

[0150] In some embodiments, the circuit breaker 220 may include a second terminal and a circuit breaker 220 body, the second terminal being connected to the circuit breaker 220 body and used for connection to an external circuit.

[0151] The following describes the electronic device 10 provided in the embodiments of this application.

[0152] Referring to Figure 15, this embodiment of the application provides an electronic device 10. The electronic device 10 may include a housing 210 and a switch module 100 as described in the above embodiment. The switch module 100 is at least partially disposed within the housing 210. The housing 210 can protect the switch module 100. The electronic device 10 includes a circuit breaker 220, which can automatically disconnect the circuit when the current in the circuit exceeds the rated current of the circuit breaker 220. Both the circuit breaker 220 and the switch module 100 are disposed within the housing 210, with the circuit breaker 220 disposed outside the housing 101. The circuit breaker 220 and the switch module 100 can be arranged along a third direction C.

[0153] For example, the number of switch modules 100 can be at least one. When the number of switch modules 100 is multiple, the multiple switch modules 100 can be arranged along a third direction C.

[0154] For example, the number of circuit breakers 220 can be at least one. When the number of circuit breakers 220 is multiple, the multiple circuit breakers 220 can be arranged along a third direction C.

[0155] In some embodiments, referring to FIG15, the electronic device 10 includes a guide rail 191 disposed in the housing 210, and the guide rail 191 can extend in a third direction C. In this case, the circuit breaker 220 and the switch module 100 are arranged along the extension 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.

[0156] In some embodiments, referring to FIG16, the circuit breaker 220 may include a first circuit breaker section 221 and a second circuit breaker section 222 connected together, the first circuit breaker section 221 and the second circuit breaker section 222 being arranged along the direction from the first sub-housing 110 to the second sub-housing 120. The dimension L3 of the second circuit breaker section 222 along the second direction B is smaller than the dimension L4 of the first circuit breaker section 221 along the second direction B, that is, the dimension L3 of the second circuit breaker section 222 along the second direction B is set to be smaller, and the dimension L4 of the first circuit breaker section 221 along the second direction B is set to be larger.

[0157] Thus, by setting the size of the second circuit breaker section 222 along the second direction B to be smaller, it is beneficial to avoid mutual interference between the second circuit breaker section 222 and the second sub-housing 120 when the circuit breaker 220 and the switch module 100 are installed in the housing 210. In addition, by setting the size of the first circuit breaker section 221 along the second direction B to be larger, the components of the circuit breaker 220 are more concentrated in the first circuit breaker section 221. The larger volume of the first circuit breaker section 221 can provide better support for the components, better distribute the weight of the components, and avoid excessive local pressure on the first circuit breaker section 221.

[0158] In some embodiments, referring to FIG14, an opening 2111 is provided on the wall of the housing 210, through which the second circuit breaker section 222 and the second sub-housing 120 can be exposed to facilitate operation of the switch module 100. The dimension of the second circuit breaker section 222 along the second direction B is equal to the dimension of the second sub-housing 120 along the second direction B. The integral structure formed by the second circuit breaker section 222 and the second sub-housing 120 has approximately the same dimension along the second direction B. The shape of this integral structure is relatively simple, and its volume is small, which helps to save space inside the housing 210. In addition, the opening 2111 allows access to the second circuit breaker sections 222 of all circuit breakers 220 and the second sub-housing 120 of all switch modules 100.

[0159] In this application, "same size" can mean "approximately the same size".

[0160] For example, the opening 2111 can be a strip opening 2111, and the opening 2111 can extend along a third direction C, thereby making the shape of the opening 2111 relatively simple.

[0161] In some embodiments, referring to FIG14, the enclosure 210 may include a first enclosure wall 211, which may be a wall on one side of the enclosure 210 along a first direction. The first enclosure wall 211 covers the circuit breaker 220 and the switch module 100, and an opening 2111 may be provided on the first enclosure wall 211. The enclosure 210 may be provided with an accommodating space 212 (FIG. 15), in which at least a portion of the circuit breaker 220 and at least a portion of the switch module are disposed. The opening 2111 communicates with the accommodating space 212.

[0162] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0163] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
