DETAILED DESCRIPTION

[0076] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described and claimed herein and by one of ordinary skill in the art without departing from the spirit and scope of the present application, and it is therefore intended that all such variations be considered as falling within the scope of the present application. Accordingly, the present application should not be limited by the following description and examples.

[0077] In the description of the application, it should be understood that, if there are these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0078] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0079] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0080] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0081] It should be noted that if an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intervening element. If an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used herein are for purposes of illustration only and are not meant to be limiting.

[0082] In the related art, the switch module can include a housing, a circuit board and a relay, the relay is electrically connected with the circuit board, and the circuit board and the relay can be arranged in the housing.

[0083] However, the relay and other devices of the switch module are arranged on the same circuit board, so that the area of the circuit board is large, thereby making the volume of the housing large, and making 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 described in combination with Figures 1-12 The switch module 100 and the electronic device 10 provided by the embodiments of the present application will be described.

[0086] Referring to Figure 1 The embodiments of the present application provide a switch module 100, which 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 be arranged in the receiving cavity 102. The first circuit board 131 and the second circuit board 132 are arranged at intervals along a first direction A, and the first circuit board 131 is connected with the second circuit board 132, thereby realizing signal transmission between the first circuit board 131 and the second circuit board 132. Wherein, the first circuit board 131 and the second circuit board 132 arranged at intervals along the first direction A can mean that there is a spacing 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, which is arranged 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 be used to control a circuit with a large current by a small current. The relay 133 can be connected with the first circuit board 131, or the first circuit board 131 can be connected with the second circuit board 132, or the relay 133 can be connected with the first circuit board 131 and the second circuit board 132 at the same time.

[0088] 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.

[0089] See Figure 4 The housing 101 includes a first sub-housing 110 and a second sub-housing 120 connected to each other, 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.

[0090] 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.

[0091] For example, see Figure 2a The switch module 100 may have a first direction A, a second direction B, and a third direction C, all of which are different. For example, the first direction A, the second direction B, and the third direction C may be perpendicular to each other. Exemplarily, 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.

[0092] In some embodiments, see 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, i.e. 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 arranged in the accommodating cavity 102 of the first sub-housing 110, because the relay 133 and the first circuit board are generally large in size, and are arranged in the accommodating cavity 102 of the large first sub-housing 110, thereby facilitating reduction of the volume of the housing 101.

[0093] The second circuit board 132 is arranged in the projection of the first circuit board 131 on the plane of the first circuit board 131, the area of the second circuit board 132 is arranged to be small, the area of the first circuit board 131 is arranged to be large, and the second circuit board 132 and the first circuit board 131 are arranged opposite along the thickness direction, thereby facilitating reduction of the total area occupied by the first circuit board 131 and the second circuit board 132, and reduction of the volume of the housing 101.

[0094] In some embodiments, referring to Figure 5 The projection of the relay 133 on the plane of the first circuit board 131 is arranged in the projection of the second circuit board 132 on the plane of the first circuit board 131, the second circuit board 132 completely covers the relay 133, and the sizes of the second circuit board 132 and the relay 133 are matched with each other, thereby facilitating reduction of the total area occupied by the second circuit board 132 and the relay 133, and reduction of the volume of the housing 101.

[0095] In other embodiments, the projection of the relay 133 on the plane of the first circuit board 131 at least partially does not overlap with the projection of the second circuit board 132 on the plane of the first circuit board 131, the second circuit board 132 partially covers the relay 133, or the side of the relay 133 away from the first circuit board 131 is completely exposed to the outside of the second circuit board 132, the second circuit board 132 does not cover the relay 133, so that at least part of the second circuit board 132 is far away from the relay 133, thereby reducing 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 with the relay 133, i.e., the relay 133 is mounted on one of the first circuit board 131 and the second circuit board 132, and the other one of the first circuit board 131 and the second circuit board 132 is provided with a control circuit, the control circuit is electrically connected with the relay 133, and the control circuit can control the relay 133. That is, the relay 133 is arranged on the first circuit board 131, and the control circuit is arranged on the second circuit board 132. Alternatively, the relay 133 is arranged on the second circuit board 132, and the control circuit is arranged on the first circuit board 131. In this way, the relay 133 and the control circuit are arranged on different circuit boards respectively, when the control circuit or the relay 133 has a problem, the circuit board with the problem can be replaced alone, without the need to replace both circuit boards, which is conducive to reducing maintenance costs.

[0097] In the embodiment in which the control circuit is arranged 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 control circuit with smaller volume is arranged on the second circuit board 132, which is conducive to reducing the overall volume of the second circuit board 132 and the control circuit, and is conducive to reducing the volume of the shell 101.

[0098] In some embodiments, referring to Figure 4 , the second circuit board 132 is provided with the first type device 134. For example, the first type device 134 is arranged on the side of the second circuit board 132 facing the first circuit board 131, or the first type device 134 is arranged on the side of the second circuit board 132 away from the first shell wall 121, without the 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 smaller, the key 135 on the second circuit board 132 is closer to the first shell wall 121, and the length of the operating member is shorter, and the key 135 is easier to press.

[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, the relay 133 and the first type device 134 are arranged on two sides of the second circuit board 132 respectively, which can make the first type device 134 farther away from the relay 133, and can reduce the adverse effects of heat of the relay 133 on the first type device 134.

[0100] In some embodiments, the second circuit board 132 can be provided with second type devices, the first type devices 134 and the second type devices can be different in volume, for example, the volume of the first type devices 134 is greater than or less than the second type devices. And / or, the first type devices and the second type devices are different in heat sensitivity, for example, the first type devices 134 are more sensitive to heat.

[0101] For example, the first type devices 134 include heat sensitive devices, when the first type devices 134 are arranged on the side of the second circuit board 132 away from the first circuit board 131, the adverse effects of the heat of the relay 133 on the heat sensitive devices can be reduced.

The second sub-shell 120 includes a first shell wall 121 Figure 4 The first shell wall 121 is arranged at the end of the second sub-shell 120 away from the first sub-shell 110, the first shell wall 121 is provided with an operating portion, the operating portion is connected with the operating member, the operating portion can be arranged opposite to the operating member along the first direction A, the end of the operating member away from the operating portion is connected with the button 135, by pressing the operating portion, the operating member can be pressed by the operating personnel. For example, the operating portion can have a certain elasticity, when the operating portion is pressed, the operating portion can be deformed to drive the operating member to press the button 135.

[0103] It should be noted that the operating portion can be indirectly connected with the button 135, for example, the operating portion can be connected with the button 135 through the operating member, in this way, the setting positions of the operating portion and the button 135 are more flexible. Alternatively, the operating portion can be directly connected with the button 135, without the need to set other structures to connect the operating portion and the button 135, the structure of the switch module 100 can be simplified, and the manufacturing cost can be reduced.

[0104] For example, the operating portion can extend along the direction parallel to the first circuit board 131, the operating portion has a certain length along the direction parallel to the first circuit board 131, so as to facilitate the operating portion to have elasticity.

[0105] In some embodiments, referring to Figure 6The second circuit board 132 is provided with a light emitting piece 140, which is arranged on the side of the second circuit board 132 away from the first circuit board 131. For example, the light emitting piece 140 can be an LED lamp. The side of the light emitting piece 140 away from the second circuit board 132 is provided with a light guide column 136. Since the light emitting piece 140 is far away from the surface of the shell 101, the light emitted by the light emitting piece 140 can be transmitted to the surface of the shell 101 through the light guide column 136.

[0106] In some embodiments, referring to Figure 7 The switch module 100 comprises a first support piece 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 piece 141. The first support piece 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 piece 141 can be high, which is conducive to improving the connection stability between the first circuit board 131 and the second circuit board 132.

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] For example, the number of the first support piece 141 is at least one. When the first support piece 141 is multiple, the multiple first support pieces 141 can be arranged at intervals. The multiple first support pieces 141 arranged at intervals can mean that there is a spacing between adjacent two first support pieces 141.

[0109] In some embodiments, referring to Figure 6 The switch module 100 comprises 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.

In addition, the pin 137 has a certain mechanical strength, which can support the second circuit board 132 to a certain extent, and can improve the connection reliability between the first circuit board 131 and the second circuit board 132.

[0110] In the embodiment provided with the pin 137 and the first support piece 141 at the same time, the pin 137 and the first support piece 141 can be arranged at intervals. The pin 137 and the first support piece 141 arranged at intervals can mean that there is a spacing between the pin 137 and the first support piece 141.

[0111] In some embodiments, referring to Figure 13 , the switch module 100 comprises a flexible cable 144, the first circuit board 131 and the second circuit board 132 are connected through the flexible cable 144, the connection between the first circuit board 131 and the second circuit board 132 is realized through the flexible cable 144, so that the connection between the first circuit board 131 and the second circuit board 132 is relatively simple, in addition, the flexible cable 144 has a high degree of deformation, so that the setting position of the flexible cable 144 is more flexible.

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

[0113] In some embodiments, referring to Figure 8 , the switch module 100 comprises a fan 138, the fan 138 can dissipate heat for devices in the housing 101, the first sub-housing 110 is provided with an air inlet 115 and an air outlet 116 (for example, the air inlet 115 and the air outlet 116 are arranged on the opposite side walls of the first sub-housing 110), Figure 4 The fan 138 is arranged on the air inlet 115 of the first sub-housing 110, the fan 138 is arranged close to the air inlet 115, the fan 138 is configured to blow air into the accommodation cavity 102, the fan 138 can drive air in the external environment to enter the accommodation cavity 102, the air brought into the accommodation cavity 102 has a relatively low temperature, the air exchanges heat with the devices 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 for the devices.

[0114] For example, referring to Figure 4 , the air inlet 115 and the air outlet 116 are arranged on the opposite side walls of the first sub-housing 110, 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, which helps air to pass through the air inlet 115 and the air outlet 116 more quickly, improves the flow of air, and helps to improve the heat dissipation performance.

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

[0116] For example, 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 6The first circuit board 131 comprises a first region and a second region connected with each other. The second circuit board 132 is arranged opposite to the first region along the first direction A. The second circuit board 132 is not overlapped with the second region in the projection of the first circuit board 131 on the plane, and the second circuit board 132 is arranged in dislocation with the second region along the first direction A. The relay 133 can be arranged on the first region. The relay 133 is arranged between the first circuit board 131 and the second circuit board 132. The fan 138 can be arranged on the second region. The fan 138 is arranged on the side of the second region facing the second circuit board 132. The second circuit board 132 does not cover the fan 138, so that the area of the second circuit board 132 is smaller, which is conducive to reducing the volume of the shell 101.

[0118] In some embodiments, referring to Figure 6 The switch module 100 comprises a second support 142 configured to support the fan 138. The fan 138 is first mounted on the second support 142, and then the second support 142 is mounted on the first circuit board 131. In this way, it is conducive to reducing the installation difficulty of the fan 138 and the first circuit board 131.

[0119] Exemplarily, referring to Figure 9 The second support 142 is provided with a first inserting member 1421 on the side facing the first circuit board 131. Figure 8 The first inserting member 1421 is arranged through the first circuit board 131, and the second support 142 and the first circuit board 131 are connected by inserting. This is conducive to reducing the connection difficulty of the second support 142 and the first circuit board 131. In addition, the first inserting member 1421 can limit the position of the second support 142 relative to the first circuit board 131.

[0120] In some embodiments, referring to Figure 9 The second support 142 is provided with a second inserting member 1422 and a third inserting member 1423 on the side facing the first circuit board 131. Figure 8 The first circuit board 131 is provided with a plug hole. The second inserting member 1422 and the third inserting member 1423 are both inserted into the plug hole, and the second support 142 and the first circuit board 131 are connected by inserting. This is conducive to reducing the connection difficulty of the second support 142 and the first circuit board 131. The second inserting member 1422 and the third inserting member 1423 can limit the position of the second support 142 relative to the first circuit board 131.

[0121] Exemplarily, referring to Figure 9The second inserting piece 1422 and the third inserting piece 1423 each include an inserting portion 1423a and a stop portion 1423b. The inserting portion 1423a extends along the first direction A. The inserting portion 1423a is connected to the second support 142 at one end along the first direction A. The stop portion 1423b is arranged at the other end of the inserting portion 1423a along the first direction A. The inserting portion 1423a is arranged in the insertion hole. The stop portion 1423b is arranged on the side of the first circuit board 131 away from the second circuit board 132. The orthogonal projection of the stop portion 1423b on the plane of the first circuit board 131 is located outside the orthogonal projection of the insertion hole on the plane of the first circuit board 131. After the second inserting piece 1422 and the third inserting piece 1423 are arranged in the insertion hole, the stop portion 1423b can prevent the second inserting piece 1422 and the third inserting piece 1423 from being accidentally removed from the insertion hole. For example, during the process of inserting the second inserting piece 1422 and the third inserting piece 1423 into the insertion hole, the inserting portion 1423a can be deformed, so that the stop portions 1423b of the second inserting piece 1422 and the third inserting piece 1423 are close to each other and are convenient to pass through the insertion hole. After the stop portions 1423b completely pass through the insertion hole, the inserting portion 1423a can return to the initial state, and the stop portions 1423b of the second inserting piece 1422 and the third inserting piece 1423 are far away from each other and are not easy to be accidentally removed from 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 arranged on the side of the first sub-housing 110 away from the second sub-housing 120. 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. The first mounting groove 161 can be used for arranging a to-be-mounted member. For example, the to-be-mounted member can be a guide rail 191. Figure 3 ).

[0123] For example, when the guide rail 191 is removed, the mounting member 150 can be pushed away from the center of the first sub-housing 110, so that the mounting member 150 is away from the guide rail 191, and the guide rail 191 and the first sub-housing 110 are separated, and the guide rail 191 is removed. When the guide rail 191 is installed, the mounting member 150 can move towards the center of the first sub-housing 110 until part of the mounting member 150 is located on the side of the guide rail 191 away from the first sub-housing 110.

[0124] In some embodiments, referring to Figure 11 The switch module 100 can include a first limiting member 171. The first limiting member 171 can prevent the mounting member 150 and the first sub-housing 110 from being accidentally separated along the second direction B. Continuing to refer to Figure 12The first limiting member 171 can include a first limiting portion 181 and a second limiting portion 182 connected to each other. The first limiting portion 181 is arranged on a side of the first sub-housing 110 away from the second sub-housing 120, and the first limiting portion 181 is connected to the mounting member 150. The first limiting portion 181 can have elasticity. When the mounting member 150 moves in the second direction B under the action of an external force, the first limiting portion 181 can be deformed in 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-housing 110. The second limiting portion 182 can prevent the mounting member 150 from being accidentally separated from the first sub-housing 110 in the second direction B.

[0125] In some embodiments, referring to Figure 12 The first limiting portion 181 extends in the third direction C, and the first limiting portion 181 has a certain length in the third direction C, which facilitates the first limiting portion 181 to have elasticity. One end of the first limiting portion 181 in the third direction C is connected to the mounting member 150, and the other end of the first limiting portion 181 in the third direction C is provided with the second limiting portion 182 toward a side of the first sub-housing 110. Figure 11 The first sub-housing 110 is provided with a limiting hole, and the second limiting portion 182 is arranged in the limiting hole through 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 first mounting portion 151 and a second mounting portion 152 connected to each other. The first mounting portion 151 and the second mounting portion 152 can be arranged in the second direction B, and 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 side walls 1521 spaced apart in the third direction C. The first side wall 1521 can be used to connect the first limiting member 171. Both of the first side walls 1521 can be located on the same side of the first mounting portion 151 in 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 in the second direction B, and the structure of the first side wall 1521 is relatively simple, which is conducive to reducing the manufacturing cost of the mounting member 150.

[0127] In some embodiments, referring to Figure 11The second mounting portion 152 comprises a second side wall 1522, and one end of each of the two first side walls 1521 is connected with the second side wall 1522, the second side wall 1522 can extend along the third direction C, and the operator can apply an external force to the mounting piece 150 through the second side wall 1522. In addition, the structure of the second side wall 1522 is relatively simple, and the manufacturing cost of the mounting piece 150 can be reduced.

[0128] In some embodiments, referring to Figure 11 The second mounting portion 152 can comprise a third side wall 1523, and one end of each of the two first side walls 1521 is connected with 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 can form the bottom wall of the first mounting groove 161. By arranging the third side wall 1523, the guide rail 191 can be prevented from shaking along the second direction B. In addition, the structure of the third side wall 1523 is relatively simple, and the manufacturing cost of the mounting piece 150 can be reduced.

[0129] In some embodiments, referring to Figure 11 The second limiting piece 172 can be arranged on the first sub-housing 110, and can prevent the mounting piece 150 from moving outward too much under the action of an external force, so that the first limiting portion 181 is deformed too much and damaged. In addition, the second limiting piece 172 can prevent the mounting piece 150 and the first sub-housing 110 from being accidentally separated along the second direction B. The second limiting piece 172 can comprise a third limiting portion 183 and a fourth limiting portion 184 connected with each other. The third limiting portion 183 extends along the second direction B, and has a certain length along the second direction B, so as to have a certain elasticity, and can be deformed, thereby reducing the installation difficulty of the mounting piece 150. One end of the third limiting portion 183 along the second direction B is connected with the first sub-housing 110, and the other end of the third limiting portion 183 along the second direction B is provided with the fourth limiting portion 184 away from one side of the second sub-housing 120. The fourth limiting portion 184 is arranged between the two first side walls 1521, and 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 piece 150 from moving outward too much under the action of an external force, so that the first limiting portion 181 is deformed too much and damaged.

[0130] For example, referring to Figure 11The distance between the fourth limiting part 184 and the third side wall 1523 is greater than the size 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 part 150 can be pushed outward, the distance that the mounting part 150 can be pushed outward is greater than the groove depth of the first mounting groove 161, the distance that the mounting part 150 can be pushed outward is greater, and when the guide rail 191 is disassembled, the guide rail 191 can be completely exposed outside the mounting part 150.

[0131] In some embodiments, the number of first limiting parts 171 can be at least one. For example, the number of first limiting parts 171 can be 1, 2, 3, or any number greater than 3. See Figure 11 When the number of first limiting parts 171 is multiple, the multiple first limiting parts 171 are arranged at intervals along the second direction B. By arranging multiple first limiting parts 171, the limiting reliability of the first limiting part 171 can be improved, and even if a part of the number of first limiting parts 171 is damaged, another part of the number of first limiting parts 171 can still play a limiting role.

[0132] In some embodiments, see Figure 12 The face of the second limiting part 182 away from the first limiting part 181 is a guide face 1821, the distance between the guide face 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, so that the thickness of the end of the second limiting part 182 close to the first mounting part 151 is smaller, and the resistance of the second limiting part 182 is smaller during the installation of the mounting part 150 and the first sub-housing 110, which can reduce the assembly difficulty of the mounting part 150 and the first sub-housing 110, and also makes the thickness of the end of the second limiting part 182 away from the first mounting part 151 larger, so that the second limiting part 182 is not easy to come out of the limiting hole, which is beneficial to improve the limiting reliability of the first limiting part 171.

[0133] In some embodiments, see Figure 11 The first sub-housing 110 is provided with a sliding groove 163 on the side away from the second sub-housing 120, and the second mounting part 152 is movably arranged in the sliding groove 163 along the second direction B, for example, the first side wall 1521 can be arranged in the sliding groove 163, and the first side wall 1521 can move in the sliding groove 163 along the second direction B, and part of the groove wall of the sliding groove 163 is arranged on the side of the first side wall 1521 away from the second sub-housing 120. The sliding groove 163 can be provided with two, and the sliding groove 163 is arranged corresponding to the first side wall 1521, and the first side wall 1521 can be arranged in the corresponding sliding groove 163.

[0134] In some embodiments, see Figure 4The first sub-housing 110 is provided with a second mounting groove 162 on the side away from the second sub-housing 120. The first mounting groove 161 and the second mounting groove 162 are oppositely and spacedly arranged along the second direction B, and are used for inserting the to-be-mounted member (for example, the guide rail 191). The first mounting groove 161 and the second mounting groove 162 can limit the two ends of the guide rail 191, so as to facilitate the assembly of the guide rail 191 and the first sub-housing 110.

[0135] For example, referring to Figure 4 First, one end of the guide rail 191 is inserted into the second mounting groove 162, and then the other end of the guide rail 191 is pressed towards the first sub-housing 110. The other end of the guide rail 191 pushes the mounting member 150 to move outward, and the first limiting portion 181 is deformed. After the other end of the guide rail 191 completely passes the mounting member 150, the external force applied to the guide rail 191 is removed, the first limiting portion 181 automatically restores the initial state and drives the mounting member 150 to move inward, so that the first mounting portion 151 (which is located on the side of the guide rail 191 away from the first sub-housing 110) is located in the first mounting groove 161, and the other end of the guide rail 191 is mounted in the first mounting groove 161. Figure 11

[0136] For example, referring to Figure 11 The surface of the first mounting portion 151 away from the second mounting portion 152 can be an inclined surface. The end of the inclined surface close to the first sub-housing 110 is arranged to be inclined away from the second mounting portion 152 relative to the end away from the first sub-housing 110. When the guide rail 191 is mounted, first, one end of the guide rail 191 is inserted into the second mounting groove 162, and then the other end of the guide rail 191 is pressed towards the first sub-housing 110. The other end of the guide rail 191 pushes the mounting member 150 to move outward through the inclined surface, so that the guide rail 191 pushes the mounting member 150 more easily.

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

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

[0141] For example, the fifth limiting portion 185 and the sixth limiting portion 186 can be arranged on the two sides of the first circuit board 131 along the second direction B. The fifth limiting portion 185 can be at least one, when the fifth limiting portion 185 is multiple, the multiple fifth limiting portions 185 can be arranged at intervals along the third direction C, and the multiple fifth limiting portions 185 are arranged on the same side of the first circuit board 131 along the second direction B. The sixth limiting portion 186 can be at least one, when the sixth limiting portion 186 is multiple, the multiple sixth limiting portions 186 can be arranged at intervals along the third direction C, and the multiple sixth limiting portions 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 The second sub-portion 112 is provided with a positioning member 174 on the side facing the second sub-housing 120, the positioning member 174 is arranged through the first circuit board 131, the positioning member 174 can position the first circuit board 131, and improve the connection reliability of the first circuit board 131 and the first sub-housing 110.

[0143] In some embodiments, referring to Figure 8The third limiting piece 173 is arranged on the side of the first sub-housing 110 away from the second sub-housing 120. The outer side of the second sub-housing 112 is arranged in the limiting groove 114 arranged on the side wall of the second sub-housing 112 in the circumferential direction. The third limiting piece 173 includes a seventh limiting part 187 and an eighth limiting part 188 connected with each other. 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 to the elasticity of the seventh limiting part 187. The seventh limiting part 187 is arranged in the limiting groove 114, and the limiting groove 114 can prevent the seventh limiting part 187 from moving along the circumferential direction of the first sub-housing 110. One end of the seventh limiting part 187 along the first direction A is connected with the first sub-housing 111.
