Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0002] With technological advancements, electronic devices (such as mobile phones and tablets) have made significant progress. As powerful tools, electronic devices have greatly facilitated users' lives and work. Electronic devices often have buttons that can be pressed to control the device. For example, buttons can control functions such as volume and power on / off.

[0003] In the related art, a mounting slot is defined on the middle frame of an electronic device, and a key is movably mounted within the mounting slot. However, when the key is subjected to a significant impact, it exerts a significant force toward the middle frame of the electronic device, which can easily damage the corresponding portion of the mounting slot's bottom. The damaged portion of the mounting slot's bottom presses inward, causing the key to move toward the middle frame. This shortens the key's pressing travel and results in poor key reliability. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the technical problem of poor reliability of key installation slots.

[0005] In order to solve the above technical problems, this application is implemented as follows: The present application discloses an electronic device, comprising: A middle frame, wherein the middle frame has an adjacent appearance surface and a mounting surface, the middle frame is provided with a mounting groove and a receiving groove, the notch of the mounting groove passes through the appearance surface, the notch of the receiving groove passes through the mounting surface, the bottom of the mounting groove is provided with at least two first through holes, the first through holes connect the mounting groove and the receiving groove, the bottom of the mounting groove has a first area, the first area is located between two adjacent first through holes; a supporting protrusion is provided in the receiving groove, and the supporting protrusion abuts against the first area.

[0006] In the embodiment of the present application, a supporting protrusion is provided in the receiving groove, and the supporting protrusion abuts against the first area of ​​the bottom of the mounting groove. In this case, the supporting protrusion can increase the strength of the bottom of the mounting groove, thereby avoiding the risk of the bottom of the mounting groove being broken, thereby preventing the key pressing travel from being affected, and thus ensuring higher reliability of the key of the electronic device.

DETAILED DESCRIPTION

[0009] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0010] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of this application can be implemented in an order other than that illustrated or described herein. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0011] In the related art, the housing of an electronic device typically includes a middle frame 100 and a battery cover 500. The display screen of the electronic device is mounted on the side of the middle frame 100 facing away from the battery cover 500. The middle frame 100 provides mounting space for the functional components of the electronic device. For example, components such as the motherboard, battery, and camera module of the electronic device can be mounted on the middle frame 100. The middle frame 100 has an adjacent appearance surface 111 and a mounting surface 112. The appearance surface 111 here refers to the exposed side of the middle frame 100, typically the side of the middle frame 100. The mounting surface 112 can be the top or bottom surface of the middle frame 100. The mounting surface 112 can be the side of the middle frame 100 facing the display screen or the side of the middle frame 100 facing the battery cover 500. The middle frame 100 is defined by a mounting slot 101 and a receiving slot 102. The notch of the mounting slot 101 extends through the appearance surface 111. The mounting slot 101 is used to mount the key module 200 of the electronic device. Specifically, the button module 200 includes a button 210, which is movably mounted within the mounting slot 101. By pressing the button 210, a user can control the functions of the electronic device. For example, the button 210 can be a volume button, thereby controlling the volume of the electronic device. Alternatively, the button 210 can be a power button, in which case the button 210 is used to turn the electronic device on and off.

[0012] The notch of the receiving slot 102 passes through the mounting surface 112. The receiving slot 102 is used to accommodate some components of the electronic device. For example, the receiving slot 102 can be used to accommodate the limit bracket 220 in the key module 200. The limit bracket 220 is used to limit the key 210, thereby preventing the key 210 from detaching from the housing. Alternatively, the receiving slot 102 can be used to accommodate the circuit board 230 in the key module 200. The key 210 triggers the corresponding control signal by pressing the circuit board 230. At least two first through holes 103 are formed at the bottom of the mounting slot 101. The first through holes 103 connect the mounting slot 101 and the receiving slot 102. The first through holes 103 are used to connect the mounting slot 101 and the receiving slot 102 so that part of the structure of the key 210 can pass through the first through holes 103 into the receiving slot 102, thereby facilitating the connection or cooperation between the key 210 and the structure in the receiving slot 102.

[0013] In the related art, at least two first through holes 103 need to be opened at the bottom of the mounting groove 101, which causes the area between the two adjacent first through holes 103 on the bottom of the mounting groove 101 to have poor strength. Therefore, when the key 210 is subjected to a large impact force, the area between the two adjacent first through holes 103 on the bottom of the mounting groove 101 is easily damaged. The damaged position will squeeze the part of the key 210 passing through the first through hole 103 inward, causing the key 210 to move toward the accommodating groove 102, thereby shortening the pressing stroke of the key 210, and thus resulting in poor reliability of the key 210.

[0014] The electronic device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0015] Please refer to Figures 1 to 15 The embodiment of the present application discloses an electronic device, which includes a middle frame 100. The middle frame 100 has an adjacent appearance surface 111 and a mounting surface 112. The appearance surface 111 of the middle frame 100 is provided with a mounting groove 101, and the mounting surface 112 of the middle frame 100 is provided with a receiving groove 102. The bottom of the mounting groove 101 has a first area 105, and the first area 105 is located between two adjacent first through holes 103 opened at the bottom of the mounting groove 101. The first area 105 here is the weak area of ​​the bottom of the mounting groove 101, and can also be understood as the easily damaged area of ​​the bottom of the mounting groove 101. A supporting protrusion 104 is provided in the receiving groove 102, and the supporting protrusion 104 abuts against the first area 105.

[0016] In the embodiment disclosed herein, a supporting protrusion 104 is provided within the receiving groove 102. The supporting protrusion 104 abuts against a first region 105 of the bottom of the mounting groove 101. Because the provision of the supporting protrusion 104 effectively increases the thickness of the first region 105, it helps reinforce the vulnerable area of ​​the bottom of the mounting groove 101. Consequently, the supporting protrusion 104 can enhance the strength of the bottom of the mounting groove 101, thereby preventing the risk of fracture at the bottom of the mounting groove 101 and, in turn, preventing an impact on the pressing stroke of the key 210. This ensures that the key 210 of the electronic device has a higher reliability.

[0017] The middle frame 100 disclosed in the present application may include side frames and a frame body, where the frame body can be understood as the upper cover of the main board. The side frames are arranged around the frame body. Through holes may be provided on the side frames, and the through holes and a part of the outer peripheral surface of the frame body may form the above-mentioned mounting grooves 101. The above-mentioned accommodating grooves 102 may be provided on the top or bottom surface of the frame body. The frame body and the side frames here may be an integrated structure, that is, the middle frame 100 is an integrated middle frame. Alternatively, the frame body and the side frames may be provided separately, in which case the middle frame 100 is an assembled structural member.

[0018] In one alternative, Figure 5 、 Figure 8 as well as Figure 11 As shown, the key module 200 further includes a limit bracket 220 and a circuit board 230. Both the limit bracket 220 and the circuit board 230 can be installed in the receiving groove 102. Specifically, the receiving groove 102 has a first side wall 1021 and a second side wall 1022. At least a portion of the first side wall 1021 forms the bottom of the mounting groove 101. It can be understood here that the first side wall 1021 and the mounting groove 101 have an overlapping structure, that is, a portion of the first side wall 1021 also forms the bottom of the mounting groove 101. In other words, the first area 105 mentioned above is also a portion of the first side wall 1021, so the support protrusion 104 abuts against a portion of the first side wall 1021. The first side wall 1021 and the second side wall 1022 can be arranged opposite each other, and the circuit board 230 can be sandwiched between the limit bracket 220 and the second side wall 1022. The side of the limit bracket 220 facing away from the circuit board 230 can abut against the first side wall 1021.

[0019] In this solution, the circuit board 230 presses the limiting bracket 220 against the first side wall 1021, while the limiting bracket 220 presses the circuit board 230 against the second side wall 1022. At this point, the structure formed by the circuit board 230 and the limiting bracket 220 forms an interference fit with the receiving slot 102, thereby ensuring that the limiting bracket 220 and the circuit board 230 can be securely installed within the receiving slot 102. Furthermore, the positioning of the limiting bracket 220 and the circuit board 230 within the same receiving slot 102 reduces the number of slots in the middle frame 100, thereby improving the strength of the middle frame 100 and simplifying the processing of the middle frame 100.

[0020] In the above embodiment, Figure 15 As shown, the button 210 may include a button body 211, a corner portion 212, and a plunger 213. Both the corner portion 212 and the plunger 213 may be disposed on the button body 211. A portion of the button body 211 is movably mounted within the mounting slot 101, and one of the corner portion 212 and the plunger 213 may extend into the receiving slot 102 through the first through-hole 103. The corner portion 212 is configured to engage with the retaining bracket 220 to limit the depth of the mounting slot 101, thereby preventing the button 210 from falling out of the middle frame 100. When a user presses the button body 211, the button body 211 moves relative to the middle frame 100. This movement of the button body 211 drives the plunger 213, which can press the circuit board 230 housed in the receiving slot 102, thereby triggering a corresponding signal and implementing the corresponding operating function. The process by which the plunger 213 presses the circuit board 230 to trigger the corresponding signal is well known in the art and will not be described in detail herein.

[0021] The first through hole 103 in the present application can be used to pass through the plunger 213. Alternatively, the first through hole 103 in the present application can be used to pass through the corner portion 212. Alternatively, one of the first through holes 103 in the present application can be used to pass through the corner portion 212, and the other first through hole 103 can be used to pass through the plunger 213.

[0022] In the above solution, the support protrusion 104 can be located between the limiting bracket 220 and the first side wall 1021. In this case, the support protrusion 104 will occupy part of the installation space of the limiting bracket 220, thereby increasing the distance between the first side wall 1021 and the second side wall 1022. While the overall outer dimensions of the middle frame 100 remain unchanged, the second side wall 1022 will be retracted a distance into the middle frame 100 to reserve a location for the installation of the support protrusion 104. However, the retraction of the second side wall 1022 into the middle frame 100 will occupy the installation space of other components in the middle frame 100, which is not conducive to the layout of the electronic device. For example, the provision of the support protrusion 104 will reduce the installation area of ​​the battery, thereby affecting the battery capacity and, in turn, the overall battery life performance of the electronic device.

[0023] Based on this, in another optional embodiment, as Figure 12 As shown, a first avoidance notch 2201 can be provided on one side of the limiting bracket 220 facing the bottom of the receiving groove 102, and at least a portion of the supporting protrusion 104 can be located within the first avoidance notch 2201. In this solution, the supporting protrusion 104 can pass through the limiting bracket 220 through the first avoidance notch 2201. At this time, the first avoidance notch 2201 on the limiting bracket 220 can avoid the supporting protrusion 104, so that the supporting protrusion 104 does not occupy the installation position of the limiting bracket 220, and is not likely to occupy the installation space of other components in the middle frame 100, thereby facilitating the layout of the electronic device. For example, in this solution, the supporting protrusion 104 can pass through the limiting bracket 220, so the installation position of the supporting protrusion 104 partially overlaps with the installation position of the limiting bracket 220, which is conducive to reducing the support protrusion 104's occupation of the installation position, thereby not easily affecting the battery installation area, and thus not easily affecting the battery capacity, thereby facilitating the battery life performance of the electronic device.

[0024] In one solution, the supporting protrusion 104 may be provided on the bottom of the receiving groove 102 , and a side of the supporting protrusion 104 facing the first sidewall 1021 may abut against the first region 105 .

[0025] In an alternative approach, Figure 3 As shown, the two ends of the support protrusion 104 can respectively abut the first side wall 1021 and the second side wall 1022. In this case, one end of the support protrusion 104 abuts the first side wall 1021, and the other end of the support protrusion 104 abuts the second side wall 1022. In this solution, the support protrusion 104 can provide stronger support for the first area 105, thereby further improving the bottom strength of the installation groove 101, thereby further reducing the risk of damage to the bottom of the installation groove 101.

[0026] In the above solution, the side of the supporting protrusion 104 facing the bottom of the receiving groove 102 can be connected to the bottom of the receiving groove 102. Alternatively, a gap can be formed between the side of the supporting protrusion 104 facing the bottom of the receiving groove 102 and the bottom of the receiving groove 102. In this case, the supporting protrusion 104 is suspended above the bottom of the receiving groove 102.

[0027] In an optional solution, the button 210 may include at least two hanging corner portions 212. In this case, the at least two hanging portions 222 may be spaced apart along the length of the button body 211. The at least two hanging corner portions 212 may correspond to the at least two first through holes 103. In this case, each first through hole 103 is configured to pass through a corresponding hanging corner portion 212. In this solution, the at least two hanging corner portions 212 connected to the button body 211 further improve the reliability of the button 210 connection.

[0028] In another optional solution, the limiting bracket 220 may include a matching portion 221 and a hanging portion 222, and the hanging portion 222 may be provided on the side of the matching portion 221 facing the bottom of the accommodating groove 102. The hanging portion 222 here can cooperate with the above-mentioned hanging corner portion 212 along the direction of the groove depth of the installation groove 101. At this time, the hanging portion 222 can limit the hanging corner portion 212, thereby avoiding the risk of the button 210 falling out of the middle frame 100. It can be understood here that the hanging portion 222 can be located between the two hanging corner portions 212, and each hanging portion 222 can be hung and matched with the two hanging corner portions 212 located on both sides thereof, that is, the two hanging corner portions 212 are respectively limited and matched with the two ends of the hanging portion 222 along the direction of the groove depth of the installation groove 101. The circuit board 230 can be sandwiched between the mating portion 221 and the second side wall 1022. The side of the mating portion 221 facing away from the circuit board 230 can abut against the first side wall 1021. The side of the hanging portion 222 facing the bottom of the receiving groove 102 can be provided with the above-mentioned first avoidance notch 2201.

[0029] In this solution, since the hanging portion 222 is located between two adjacent hanging corner portions 212 , a first avoiding notch 2201 is provided on the hanging portion 222 , so that the supporting protrusion 104 can be avoided.

[0030] Optionally, the hanging portion 222 may include a connecting protrusion 2221, a first limiting protrusion 2222, and a second limiting protrusion 2223. The first limiting protrusion 2222 and the second limiting protrusion 2223 are located on opposite sides of the connecting protrusion 2221 along the length direction of the receiving groove 102. The first limiting protrusion 2222 is engaged with one of the hanging corner portions 212 in a direction of the groove depth of the installation groove 101, and the second limiting protrusion 2223 is engaged with the other hanging corner portion 212 in a direction of the groove depth of the installation groove 101. The first avoiding notch 2201 may be provided on the connecting protrusion 2221.

[0031] In another optional solution, the first avoidance notch 2201 is not limited to being provided on the hooking portion 222, but can also be provided on the mating portion 221. When a hooking portion 222 is mated with a corner portion 212, the first avoidance notch 2201 can be provided on a portion of the mating portion 221 between two adjacent hooking portions 222.

[0032] Alternatively, when the first through hole 103 is used to pass through the plunger 213 , since the area corresponding to the plunger 213 does not have the hanging portion 222 , the first avoiding notch 2201 can be provided on the matching portion 221 .

[0033] In an optional embodiment, the button 210 may be a volume button, and the volume member may have two plungers 213 and two hanging corners 212, and the two hanging corners 212 may be located in the middle of the volume button. In this case, due to the longer length of the volume button, the two hanging corners 212 of the volume button may be located between the two plungers 213 on either side thereof, that is, the two plungers 213 are located at both ends of the volume button, and the two hanging corners are located in the middle of the volume button. Due to the longer length of the volume button, an anti-sway protrusion 214 is further provided on the side of the button body 211 of the volume button facing the mounting slot 101, and the anti-sway protrusion 214 is located between the two hanging corners 212. The two ends of the anti-sway protrusion 214 protrude from the button body 211 along the thickness direction of the button body 211, so that the anti-sway protrusion 214 can abut and cooperate with the two opposite side walls of the mounting slot 101, thereby preventing the button body 211 from shaking along its thickness direction within the mounting slot 101. When the key 210 is pressed, the presence of the anti-sway protrusion 214 aggravates the impact of the key 210 on the first area 105. In the present application, the anti-sway protrusion 214 faces the first area 105, and the first area 105 is provided with the supporting protrusion 104. The supporting protrusion 104 can effectively increase the strength of the first area 105, thereby effectively reducing the risk of the first area 105 being damaged by the anti-sway protrusion 214.

[0034] When the button 210 is a volume button, the at least two first through holes 103 are used to pass through the corresponding corner portions 212. To allow the plunger 213 to pass into the receiving groove 102, a second through hole 106 may be further defined at the bottom of the mounting groove 101, through which the plunger 213 may extend into the receiving groove 102.

[0035] Because the power button is relatively short, the plunger 213 is typically located in the middle of the button 210. This location is less prone to breakage, and the switch component is less likely to damage the middle frame 100. Of course, the solution in this application can also be applied to the power button to reinforce the weak area of ​​the middle frame 100 corresponding to the power button.

[0036] The present application does not limit the specific position of the first avoidance notch 2201 on the limiting bracket 220 , and the first avoidance notch 2201 can be flexibly opened according to the specific structure of the button 210 .

[0037] In the above solution, when the thickness of the electronic device is relatively thin, the circuit board 230 and the supporting protrusion 104 may easily interfere with each other.

[0038] Based on this, in an optional solution, a second clearance notch 2301 can be provided on the side of the circuit board 230 facing the bottom of the receiving groove 102, and the supporting protrusion 104 can be positioned opposite the second clearance notch 2301. In this solution, the circuit board 230 is positioned away from the supporting protrusion 104 to meet the strength requirements of the supporting protrusion 104 and the thickness requirements of the entire device.

[0039] However, the second avoidance notch 2301 formed on the circuit board 230 will inevitably occupy the wiring width of the circuit board 230 , thus affecting the wiring performance of the circuit board 230 .

[0040] In another optional embodiment, as Figures 5 to 7 As shown, the circuit board 230 may include a main body 231 and an extension 232, which is bent relative to the main body 231. At least a portion of the main body 231 may be located within the receiving slot 102. The main body 231 may be sandwiched between the limiting bracket 220 and the second sidewall 1022. A second avoidance notch 2301 may be defined on the side of the main body 231 facing the bottom of the receiving slot 102. The extension 232 is located on the side of the main body 231 facing away from the bottom of the receiving slot 102. The extension 232 may extend outside the receiving slot 102 through the notch of the receiving slot 102 and be attached to the mounting surface 112. The main body 231 may be connected to the motherboard of the electronic device, thereby achieving electrical conduction between the circuit board 230 and the motherboard of the electronic device.

[0041] In this solution, to avoid the support protrusion 104, a second avoidance notch 2301 is provided on the side of the plate body 231 facing the bottom of the accommodating groove 102. At the same time, to meet the routing requirements of the circuit board 230, an extended routing portion extends upward from a local position on the side of the plate body 231 facing away from the notch of the accommodating groove 102 to meet the routing requirements of the circuit board 230. Therefore, this solution can not only meet the requirements of the circuit board 230 avoiding the support protrusion 104, but also meet the routing width of the circuit board 230, thereby further improving the assembly performance of the electronic device. In particular, the first avoidance notch 2201 and the second avoidance notch 2301 are arranged correspondingly, and the support protrusion 104 is simultaneously inserted into the first avoidance notch 2201 and the second avoidance notch 2301.

[0042] Further, if Figure 6As shown, the electronic device may further include a first adhesive layer 400, which may be applied to the mounting surface 112. Here, the first adhesive layer 400 is used to bond structures on the electronic device that mate with the middle frame 100. For example, the first adhesive layer 400 may bond the display screen to the middle frame 100. Alternatively, the first adhesive layer 400 may be used to bond the middle frame 100 to the battery cover 500. The first adhesive layer 400 may define a clearance space 401, and the extension portion 232 may be disposed opposite the clearance space 401 to expose the extension portion 232.

[0043] In this solution, the first adhesive layer 400 can avoid the extension portion 232, thereby avoiding the problem of uneven thickness of the installation area of ​​the electronic device caused by the overlap of the first adhesive layer 400 and the extension portion 232.

[0044] Optionally, the avoidance space 401 may be a notch, a gap, a through hole, a groove or the like. Of course, the avoidance space 401 may also be other structures, which is not limited in this document.

[0045] In an optional solution, the mounting surface 112 may be a surface of the middle frame 100 facing the battery cover 500. The first adhesive layer 400 may be used to bond the middle frame 100 and the battery cover 500.

[0046] In another optional embodiment, as Figure 8 As shown, the limiting bracket 220 may have a second area 2203 arranged opposite to the first area 105, and a gap 300 may be formed between the first area 105 and the second area 2203. Specifically, the gap 300 is formed on the side of the limiting bracket 220 close to the bottom of the groove and facing the first area 105. In this solution, when the first area 105 breaks, the position where the first area 105 breaks is squeezed inward. Since there is a certain gap 300 between the first area 105 and the second area 2203 of the limiting bracket 220, the position where the first area 105 breaks has a certain deformation space, so it is not easy to directly abut against the limiting bracket 220, thereby further avoiding the risk of shortening the pressing stroke of the key 210, thereby further improving the reliability of the key 210. In particular, the gap 300 is formed in the hanging portion 222, located between the hanging portion 222 and the first side wall 1021.

[0047] Optionally, a gap 300 is formed between the aforementioned hook portion 222 and the first region 105. In other words, the aforementioned second region 2203 is provided on the hook portion 222. The surface of the hook portion 222 facing the first region 105 may be an inclined surface, which is referred to as the second region 2203. The inclined surface is inclined toward the side facing away from the first region 105, and the aforementioned gap 300 is formed between the inclined surface and the first region 105.

[0048] In the above embodiment, due to the limitation of the limiting bracket 220, the supporting protrusion 104 is relatively small along the depth direction of the receiving groove 102, which can be understood here as a relatively small height dimension of the supporting protrusion 104. The relatively small height dimension of the supporting protrusion 104 reduces the support range for the first area 105, thus still posing a greater risk of damage to the first area 105.

[0049] Based on this, in an optional embodiment, as Figures 9 to 11 As shown, the supporting protrusion 104 may include a first supporting protrusion 1041 and a second supporting protrusion 1042. The first supporting protrusion 1041 may be disposed at the bottom of the receiving groove 102. The first supporting protrusion 1041 may abut against the first region 105 and pass through the first avoiding notch 2201. The second supporting protrusion 1042 may be disposed on a side of the limiting bracket 220 facing away from the mounting groove 101. The second supporting protrusion 1042 may abut against the circumference of the first avoiding notch 2201 of the limiting bracket 220.

[0050] In this solution, the first support protrusion 1041 abuts the first region 105, while the position-limiting bracket 220 simultaneously avoids the first support protrusion 1041 through the first position-limiting notch 2201. The second support protrusion 1042 abuts the first position-limiting notch 2201 of the position-limiting bracket 220 on the circumferential direction of the side facing the second sidewall 1022. Therefore, the second support protrusion 1042 supports the position-limiting bracket 220, and then supports the first region 105 through the position-limiting bracket 220. This not only reduces the internal space occupied, but also further increases the support range for the first region 105, thereby improving the support strength for the first region 105. In particular, the first support protrusion 1041 and the second support protrusion 1042 can be shaped like a cylinder, a square column, an elliptical cylinder, or any other shape, which is not specifically limited in this application. Meanwhile, in some embodiments, the radius of the first support protrusion 1041 is smaller than the radius of the second support protrusion 1042. The first support protrusion 1041 and the second support protrusion 1042 are connected to each other, with the first support protrusion 1041 abutting against the first sidewall 1021, and the second support protrusion 1042 abutting against the second sidewall 1022. In some embodiments, the second support protrusion 1042 abuts against the circumference of the connecting protrusion 2221 facing the second sidewall 1022.

[0051] Optionally, a portion of the second support protrusion 1042 can be located directly above the first support protrusion 1041. In this case, the second support protrusion 1042 can be located on the side of the notch of the first support protrusion 1041 facing the accommodating groove 102. In this case, the second support protrusion 1042 can abut against the position directly above the first avoidance notch 2201 opened in the limiting bracket 220.

[0052] In another embodiment, the second support protrusion 1042 can be connected to the second side wall 1022, and there can be a certain gap between the second support protrusion 1042 and the first support protrusion 1041. The end of the second support protrusion 1042 away from the second side wall 1022 can abut against the limit space.

[0053] In the above embodiment, the side of the support protrusion facing the receiving groove 102 can abut against the bottom wall of the first avoidance notch 2201. In this case, the support protrusion can provide a certain support for the limiting bracket 220. Specifically, the side of the first support protrusion 1041 facing the notch of the receiving groove 102 can abut against the bottom wall of the first avoidance notch 2201.

[0054] In another optional solution, a recessed portion 2202 may be formed on the side of the limiting bracket 220 away from the mounting slot 101 , and the recessed portion 2202 may be provided around the first avoiding notch 2201 . At least a portion of the second supporting protrusion 1042 may abut against the recessed portion 2202 .

[0055] In this solution, at least a portion of the second supporting protrusion 1042 is located in the recessed portion 2202 , thereby facilitating further reduction in the size of the electronic device.

[0056] In the above solution, the side of the second supporting protrusion 1042 facing the notch of the accommodating groove 102 can abut against the top wall of the recessed portion 2202 , thereby facilitating further enhancing the supporting effect on the limiting bracket 220 .

[0057] When the circuit board 230 is provided with the second avoiding notch 2301 , the second avoiding notch 2301 can be used to avoid the second supporting protrusion 1042 .

[0058] In one alternative, the first support protrusion 1041 is smaller than the second support protrusion 1042 along the length of the receiving groove 102. In this approach, the smaller dimension of the first support protrusion 1041 along the length of the receiving groove 102 facilitates the provision of the first avoidance notch 2201 on the limiting bracket 220, thereby facilitating the avoidance of the first support protrusion 1041. The larger dimension of the second support protrusion 1042 along the length of the receiving groove 102 facilitates increased support strength for the first region 105. Therefore, this approach can further enhance the support strength for the first region 105.

[0059] Alternatively, as Figure 13 As shown, the first avoiding notch 2201 and the recessed portion 2202 can both be provided on the aforementioned connecting protrusion 2221 .
