Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to a connection structure and an electronic device. Background Art

[0002] As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of them is the emergence of foldable mobile phones, computers and other electronic devices. The flexible screens of foldable electronic devices can flexibly change modes according to different usage scenarios. At the same time, they also have a high screen-to-body ratio and clarity. For example, when the phone is folded, it can be only the size of a traditional phone, which is convenient to carry, and when unfolded, it can have the display size of a tablet. These features make foldable devices one of the most popular products.

[0003] At present, foldable electronic devices usually include a first shell and a second shell that can rotate relative to each other. The first shell and the second shell can move toward each other to a folded state, or the first shell and the second shell can also move away from each other to an unfolded state. In order to enable the first shell and the second shell to maintain the folded state for a long time, a locking member with a locking position is provided on the first shell, and a retractable locking tongue is usually provided on the second shell. One end of the locking tongue is located in the second shell, and the other end of the locking tongue can be retracted into the second shell or extended out of the second shell. When the first shell and the second shell are in the folded state, the other end of the locking tongue extends out of the second shell and extends into the locking position of the locking member, so that the first shell and the second shell are locked, so that the electronic device remains in the folded state. When the first shell and the second shell are in the unfolded state, the other end of the locking tongue retracts into the second shell, and the locking tongue is separated from the locking position of the locking member, so that the first shell and the second shell are unfolded.

[0004] However, when a user uses an electronic device, due to scenarios such as falling, the connection between the locking component and the first shell may become loose or even the locking component may detach from the first shell, which may affect the reliability and performance of the electronic device. Summary of the invention

[0005] The present application provides a connection structure and an electronic device, which can prevent the electronic device from having a loose connection with a locking member and a first shell or even detaching the locking member from the first shell in scenarios such as falling, thereby avoiding affecting the reliability and performance of the electronic device.

[0006] In a first aspect, an embodiment of the present application provides a connection structure, which is applied to an electronic device, and the connection structure comprises at least: a first shell, a locking part and a snap-in part; the first shell has a first surface and a second surface adjacent to each other; a first groove is provided on the first surface, and the locking part is located in the first groove; a second groove connected to the first groove is provided on the second surface, and the snap-in part is located in the second groove, and the snap-in part is detachably connected to the locking part to fix the locking part in the first groove.

[0007] The connection structure provided in the embodiment of the present application is characterized in that a first groove is opened on the first surface of the first shell, and a second groove is opened on the second surface of the first shell, the second groove is communicated with the first groove, a locking component is arranged in the first groove, a snap-in component is located in the second groove, the snap-in component and the locking component are detachably connected, and the locking component can be fixed in the first groove of the first shell by the snap-in component. In this way, it is possible to avoid a loose connection between the locking component and the first shell or even a detachment of the locking component from the first shell in scenarios such as the electronic device falling, thereby avoiding affecting the reliability and performance of the electronic device, and further ensuring the user experience.

[0008] In a possible implementation, the locking member includes: a locking portion and a connecting portion connected to the locking portion; the clamping member is detachably connected to the connecting portion to fix the locking member in the first groove.

[0009] By designing the locking component to include a connected locking portion and a connecting portion, the locking portion is used to lock with a structure other than the connecting structure on the electronic device, and the connecting portion is used to connect with the first shell. Specifically, the snap-fit ​​component and the connecting portion of the locking component are detachably connected to fix the locking component in the first groove of the first shell, thereby ensuring that the locking component is fixed in the first groove of the first shell through the snap-fit ​​component.

[0010] In a possible implementation, the first groove includes: a first recess and a second recess connected to the first recess; the second recess is also connected to the second groove; the locking portion is located in the first recess, the connecting portion is located in the second recess, and the clip is detachably connected to the connecting portion.

[0011] By designing the first groove to include a first recessed portion and a second recessed portion that are connected, the locking portion of the locking member is located in the first recessed portion, the connecting portion of the locking member is located in the second recessed portion, and the second recessed portion is also connected to the second groove. The snap-fit ​​member located in the second recess is detachably connected to the connecting portion located in the second recess, so that the snap-fit ​​member can be fixed in the first recess of the first shell.

[0012] In a possible implementation manner, an extension direction of the second recessed portion and an extension direction of the second groove are perpendicular to each other.

[0013] By designing the extension direction of the second recess of the first groove and the extension direction of the second recess to be perpendicular to each other, the connecting portion of the locking member is located in the second recess of the first recess, and the snap-in member is located in the second recess. Since the second recess is communicated with the second recess, when the snap-in member located in the second recess cooperates with the connecting portion located in the second recess, the vertical cooperation connection reliability is high and the structural design is easy to implement.

[0014] In a possible implementation, the clamping member is provided with the following mutually spaced apart grooves on one side of the bottom of the second groove: a first notch, a second notch and a third notch, wherein the second notch is located between the first notch and the third notch; a first elastic arm is formed between the first notch and the second notch, and a second elastic arm is formed between the second notch and the third notch; the first elastic arm and the second elastic arm are clamped at both ends of the connecting portion.

[0015] By sequentially arranging a first notch, a second notch and a third notch spaced apart from each other on the snap-fitting component, a first elastic arm is formed between the first notch and the second notch, and a second elastic arm is formed between the second notch and the third notch. In this way, the first elastic arm and the second elastic arm are snapped at both ends of the connecting part, thereby realizing a detachable connection between the snap-fitting component and the connecting part, and further realizing a detachable connection between the snap-fitting component and the locking component.

[0016] In a possible implementation, a first opening and a second opening are provided at both ends of the connection portion. The first elastic arm is located in the first opening, and the second elastic arm is located in the second opening, so as to clamp the connecting member onto the connection portion.

[0017] By providing a first opening and a second opening at both ends of the connecting part, when the first elastic arm and the second elastic arm are clamped at the two ends of the connecting part, the first elastic arm is located in the first opening and the second elastic arm is located in the second opening. In this way, the first opening can assist in limiting and fixing the first elastic arm, and the second opening can assist in limiting and fixing the second elastic arm, so that the structural stability of the clamping part when it is clamped on the connecting part is better.

[0018] In a possible implementation, the first elastic arm includes a first end and a second end relative to each other, the first end of the first elastic arm being an end of the first elastic arm close to the bottom of the second groove, and the second end of the first elastic arm being an end of the first elastic arm away from the bottom of the second groove; the second elastic arm includes a first end and a second end relative to each other, the first end of the second elastic arm being an end of the second elastic arm close to the bottom of the second groove, and the second end of the second elastic arm being an end of the second elastic arm away from the bottom of the second groove; the distance between the first end of the first elastic arm and the first end of the second elastic arm is smaller than the distance between the second end of the first elastic arm and the second end of the second elastic arm.

[0019] The distance between one end of the first elastic arm close to the bottom of the second groove and one end of the second elastic arm close to the bottom of the second groove is smaller than the distance between one end of the first elastic arm away from the bottom of the second groove and one end of the second elastic arm away from the bottom of the second groove. In this way, the first elastic arm and the second elastic arm of the clamping member form an inverted structure facing the bottom of the second groove. When the first elastic arm and the second elastic arm of the clamping member are clamped at the two ends of the connecting part of the locking member, the first end of the first elastic arm and the first end of the second elastic arm grasp the two ends of the connecting part. Therefore, the inverted structure design can make the connection between the first elastic arm and the second elastic arm and the two ends of the connecting part better, avoid separation between the connecting part of the clamping member and the locking member, thereby avoiding the phenomenon of the locking member detaching from the first groove of the first shell.

[0020] In a possible implementation manner, the first end of the first elastic arm is inclined toward the second elastic arm; and the first end of the second elastic arm is inclined toward the first elastic arm.

[0021] The first end of the first elastic arm is inclined toward the second elastic arm, and the first end of the second elastic arm is inclined toward the first elastic arm, so as to ensure that the distance between the end of the first elastic arm close to the bottom of the second groove and the end of the second elastic arm close to the bottom of the second groove is smaller than the distance between the end of the first elastic arm away from the bottom of the second groove and the end of the second elastic arm away from the bottom of the second groove, so that the first elastic arm and the second elastic arm of the clamping member form an inverted structure facing the bottom of the second groove.

[0022] In a possible implementation manner, a dimension of the first end of the first elastic arm in the length direction of the clamping member is greater than a dimension of the first end of the second elastic arm in the length direction of the clamping member.

[0023] The dimension of the first end of the first elastic arm in the length direction of the clip is larger than the dimension of the first end of the second elastic arm in the length direction of the clip, so as to ensure that the distance between the end of the first elastic arm close to the bottom of the second groove and the end of the second elastic arm close to the bottom of the second groove is smaller than the distance between the end of the first elastic arm away from the bottom of the second groove and the end of the second elastic arm away from the bottom of the second groove, so that the first elastic arm and the second elastic arm of the clip form an inverted structure facing the bottom of the second groove.

[0024] In a possible implementation, a third opening is provided in the middle of the connecting portion, and the opening has a first inner wall and a second inner wall opposite to each other;

[0025] The first elastic arm and the second elastic arm are both located in the third opening, the first elastic arm abuts against the first inner wall, and the second elastic arm abuts against the second inner wall, so as to clamp the connecting member on the connecting portion.

[0026] In a possible implementation, the first elastic arm includes a first end and a second end opposite to each other, the first end of the first elastic arm is an end of the first elastic arm close to the bottom of the second groove, and the second end of the first elastic arm is an end of the first elastic arm away from the bottom of the second groove;

[0027] The second elastic arm comprises a first end and a second end opposite to each other, the first end of the second elastic arm is an end of the second elastic arm close to the bottom of the second groove, and the second end of the second elastic arm is an end of the second elastic arm away from the bottom of the second groove;

[0028] The first end of the first elastic arm forms a first buckling portion, and the first buckling portion extends toward the first notch; the first end of the second elastic arm forms a second buckling portion, and the second buckling portion extends toward the third notch.

[0029] In a possible implementation manner, a plurality of protrusions are provided on a side of the connecting portion facing away from the locking portion, and the protrusions abut against an inner wall of the second recess.

[0030] By providing a plurality of protrusions on the side of the connecting portion facing away from the locking portion, since the connecting portion of the locking piece is located in the second recessed portion of the first groove, the plurality of protrusions can abut against the inner wall of the second recessed portion. In this way, the plurality of protrusions of the connecting portion and the inner wall of the second recessed portion have an interference fit, which can make the connection between the connecting portion and the inner wall of the second recessed portion tighter, thereby further preventing the connecting portion of the locking piece from detaching from the second recessed portion of the first groove.

[0031] In a possible implementation manner, a locking position is provided on a side of the locking portion facing away from the connecting portion.

[0032] A locking position is provided on the side of the locking portion of the locking element away from the connecting portion, and the locking position is used to lock with a structure other than the connecting structure on the electronic device.

[0033] In a second aspect, an embodiment of the present application provides an electronic device, which includes at least: any one of the connection structures described above.

[0034] An electronic device provided in an embodiment of the present application includes a connection structure, wherein a first groove is provided on a first surface of a first shell, and a second groove is provided on a second surface of the first shell, the second groove is communicated with the first groove, a locking member is arranged in the first groove, a snap-connector is located in the second groove, the snap-connector and the locking member are detachably connected, and the locking member can be fixed in the first groove of the first shell by the snap-connector, so that a loose connection between the locking member and the first shell or even detachment of the locking member from the first shell can be avoided in scenarios such as the electronic device falling, thereby avoiding affecting the reliability and performance of the electronic device, and further ensuring the user experience when using the electronic device.

[0035] In a possible implementation, the electronic device is a foldable electronic device; the foldable electronic device further comprises: a second housing and a shaft assembly; the second housing is rotatably connected to the first housing of the connection structure via the shaft assembly; a retractable lock tongue is provided on the second housing, and one end of the lock tongue is located in the second housing;

[0036] When the foldable electronic device is in a folded state, the other end of the locking tongue is engaged in the locking member of the connecting structure to lock the first shell and the second shell; when the foldable electronic device is in an unfolded state, the other end of the locking tongue is located outside the second shell.

[0037] In this way, when the foldable electronic device is in a folded state, that is, the first shell and the second shell are in a folded state, the lock tongue on the second shell extends out of the second shell and extends into the locking member on the first shell. Specifically, the lock tongue extends into the locking position on the locking member and cooperates with the locking position, so that the first shell and the second shell are locked, so that the foldable electronic device remains in a folded state. When the foldable electronic device switches from a folded state to an unfolded state, the lock tongue on the second shell shrinks into the second shell, and the lock tongue is separated from the locking member. Specifically, the lock tongue is separated from the locking position of the locking member, so that the first shell and the second shell are unfolded. When the foldable electronic device is in an unfolded state, that is, when the first shell and the second shell are in an unfolded state, the other end of the lock tongue is located outside the second shell.

[0071] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] An embodiment of the present application provides an electronic device, which may include but is not limited to a foldable fixed terminal or mobile terminal such as a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen TV, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, etc.

[0073] The electronic device can be folded into two layers or three layers, or can also be folded into more layers.

[0074] In the embodiment of the present application, the electronic device is a mobile phone, and a foldable electronic device that can be folded into two layers is taken as an example for description.

[0075] Figure 1 A schematic diagram of the structure of an electronic device in a flattened state provided in an embodiment of the present application, Figure 2 A schematic diagram of the structure of an electronic device in a folding process provided by an embodiment of the present application, Figure 3 A schematic diagram of the structure of an electronic device in a folded state provided in an embodiment of the present application.

[0076] See also Figure 1 and Figure 2 As shown, the electronic device 200 includes a first housing 110 and a second housing 210, and the first housing 110 and the second housing 210 are rotatably connected, wherein the first housing 110 and the second housing 210 may be middle frames. The first end of the first housing 110 and the first end of the second housing 210 are rotatably connected, and specifically, the first housing 110 and the second housing 210 may be rotatably connected through a hinge assembly, a shaft assembly 220 or a flexible board.

[0077] The first housing 110 and the second housing 210 can move toward each other, that is, fold relative to each other, and finally the first housing 110 and the second housing 210 abut against each other and fold relative to each other, so that the electronic device 200 is in a folded state. Figure 3Alternatively, the first housing 110 and the second housing 210 may also move in opposite directions, that is, unfold relatively, and finally the first housing 110 and the second housing 210 are flattened and located in the same plane, so that the electronic device 200 is in an unfolded state, as shown in FIG. Figure 1 as shown in .

[0078] Continue to see Figure 1 and Figure 2 As shown, a retractable lock tongue 2111 is provided on the second housing 210, that is, the lock tongue 2111 can be extended out of the second housing 210, or the lock tongue 2111 can be retracted into the second housing 210. In the embodiment of the present application, the width direction of the electronic device 200 is the x direction, and the thickness direction of the electronic device 200 is the z direction, that is, the lock tongue 2111 can move along the x direction, so that it can be retracted and arranged on the second housing 210, wherein the movement direction of the lock tongue 2111 extending out of the second housing 210 is the +x direction, and the movement direction of the lock tongue 2111 retracting into the second housing 210 is the -x direction.

[0079] The second housing 210 is provided with a locking member 120, and a locking tongue 2111 can be matched and arranged in the locking member 120. When the first housing 110 and the second housing 210 move toward each other until the electronic device 200 is in a folded state, the locking tongue 2111 extends out of the second housing 210 and is located in the locking member 120 of the first housing 110. The relative movement between the first housing 110 and the second housing 210 is limited by the locking tongue 2111 and the locking member 120, so that the first housing 110 and the second housing 210 are locked, so that the electronic device 200 can be kept in the folded state for a long time, and the occurrence of the electronic device 200 being unfolded due to a slight touch or misoperation is reduced, which helps to improve the user experience.

[0080] The second housing 210 is also provided with a button 2113, and when the button 2113 is pressed, the direction in which the button 2113 moves is the +z direction, and the opposite direction is the -z direction. When the electronic device 200 needs to be unfolded, the button 2113 can be pressed to retract the lock tongue 2111 into the second housing 210, so that the lock tongue 2111 is separated from the locking member 120, and the first housing 110 and the second housing 210 are rotated to move the two oppositely until the electronic device 200 is in the unfolded state.

[0081] A side end cover 211 may be provided on the end of the second shell 210 facing away from the first shell 110 , the first end 110a of the first shell is opposite to the first end 210a of the second shell, the second end 110b of the first shell is opposite to the second end 210b of the second shell, and the button 2113 and the lock tongue 2111 may be arranged on the side end cover 211 .

[0082] Among them, the end of the second shell 210 facing away from the first shell 110 may have a first side 2101 and a second side 2102, the first side 2101 may be the side of the side end cover 211 of the second shell 210 facing the first shell 110, the second side 2102 may be adjacent to the first side 2101, and the second side 2102 may be the end face of the side end cover 211.

[0083] Specifically, the button 2113 can be set on the second side surface 2102, the lock tongue 2111 can be located below the button 2113 (in the +z direction), one end of the lock tongue 2111 is located inside the second shell 210, and the other end of the lock tongue 2111 can extend from the first side surface 2101 of the second shell 210 to the outside of the second shell 210, or retract into the second shell 210.

[0084] Specifically, a retractable lock tongue 2111 is provided on the second shell 210, and a button 2113 is also provided on the second shell 210. A transmission torsion spring (not shown in the figure) can also be provided in the second shell 210. Pressing the button 2113 can move the transmission torsion spring, and the transmission torsion spring can drive the lock tongue 2111 to contract, thereby separating the lock tongue 2111 from the locking component 120.

[0085] In addition, the second shell 210 may have a receiving groove 2112 , the notch of the receiving groove 2112 is located on the second side surface 2102 of the second shell 210 , and at least one end of the locking tongue 2111 is located in the receiving groove 2112 .

[0086] When the pressing force on the button 2113 is removed, the rebound of the button 2113 can be realized in various ways, such as an elastic member (not shown in the figure) can be further provided in the second housing 210, and one end of the lock tongue 2111 can be in contact with the inner wall of the second housing 210 through the elastic member. When the button 2113 is pressed, the output end of the button 2113 drives the lock tongue 2111 to shrink into the second housing 210, and the lock tongue 2111 compresses the elastic member. When the lock tongue 2111 is separated from the locking member 120, the button 2113 is released, and the rebound force of the compressed elastic member can push the lock tongue 2111 to move in the opposite direction, so that the other end of the lock tongue 2111 extends out of the second housing 210, and at the same time drives the transmission torsion spring to move, thereby pushing the button 2113 to return to its original position.

[0087] It should be understood that the electronic device 200 may also include other structural components to ensure that the functions of the electronic device 200 can be realized. Specifically, the electronic device 200 may also include: a camera, a flash, a processor, a memory, a sensor, a display screen, an antenna, etc.

[0088] It is understandable that currently when users use electronic devices, due to scenarios such as falling, it is easy for the connection between the locking component and the first shell to become loose or even for the locking component to detach from the first shell, which will affect the reliability and performance of the electronic device.

[0089] At present, when the locking part is fixed on the first housing, a groove is provided at one end of the first housing away from the second housing, and the locking part is fixed in the groove. For example, in the related art, the locking part is usually fixed in the groove of the first housing by screws. In order to prevent the locking part from moving in a direction perpendicular to the screws, limited steel sheets are generally provided at both ends of the locking part to ensure that the locking part does not move relative to the groove on the first housing. However, in this fixing scheme, more parts are used, which will increase the space occupied by the parts inside the electronic device and affect the reasonable layout of other devices.

[0090] Based on this, an embodiment of the present application provides a connection structure and an electronic device having the connection structure to solve the above technical problems.

[0091] The following takes a specific embodiment as an example and describes the specific structure of the connection structure and the electronic device having the connection structure in conjunction with the accompanying drawings.

[0092] Reference Figure 4 As shown, the embodiment of the present application provides a connection structure 100, which can be applied to an electronic device 200. Specifically, referring to Figure 5 and Figure 6 As shown, the connection structure 100 may include at least: a first housing 110, a locking member 120 and a clamping member 130, the first housing 110 having a first surface 1101 and a second surface 1102 adjacent to each other (see Figure 7 and Figure 8 As shown in the figure, a first groove 111 is formed on the first surface 1101, and the locking member 120 is located in the first groove 111. A second groove 112 connected to the first groove 111 is formed on the second surface 1102, and the clamping member 130 is located in the second groove 112. Moreover, the clamping member 130 is detachably connected to the locking member 120 to fix the locking member 120 in the first groove 111.

[0093] In the connection structure 100, a first groove 111 is opened on the first surface 1101 of the first shell 110, and a second groove 112 is opened on the second surface 1102 of the first shell 110. The second groove 112 is communicated with the first groove 111, and the locking member 120 is arranged in the first groove 111. The snap-connecting member 130 is located in the second groove 112. The snap-connecting member 130 and the locking member 120 are detachably connected. The locking member 120 can be fixed in the first groove 111 of the first shell 110 by the snap-connecting member 130. In this way, it is possible to avoid the phenomenon that the locking member 120 and the first shell 110 are loosely connected or even the locking member 120 is detached from the first shell 110 in scenarios such as the electronic device 200 falling, thereby avoiding affecting the reliability and performance of the electronic device 200, and thus ensuring the user experience.

[0094] In addition, it can be understood that the locking member 120 is assembled and fixed in the first groove 111 of the first shell 110 by the snap-fit ​​member 130, which occupies a small space in the electronic device 200, thereby ensuring the overall appearance of the electronic device 200. Moreover, the three parts (i.e., the first shell 110, the locking member 120 and the snap-fit ​​member 130) can be locked with each other, which is reliable and has a simple structure, thereby greatly reducing the number of parts and the space occupied inside the whole machine.

[0095] Moreover, compared with the connection method of the prior art of fixing the locking component 120 on the first shell 110 by spot welding or gluing, the embodiment of the present application adopts a mechanical fixation method. The connection will not fail if the parts are not damaged, which effectively avoids the risk of failure caused by corrosion in the environment of conventional spot welding or gluing solutions.

[0096] like Fig. 9 and Fig.10 As shown, in the embodiment of the present application, the locking member 120 may include: a locking portion 121 and a connecting portion 122 connected to the locking portion 121 , and the clamping member 130 is detachably connected to the connecting portion 122 to fix the locking member 120 in the first groove 111 .

[0097] By designing the locking component 120 to include a connected locking portion 121 and a connecting portion 122, the locking portion 121 is used to lock with a structure other than the connecting structure 100 on the electronic device 200, and the connecting portion 122 is used to connect with the first shell 110. Specifically, the snap-fit ​​component 130 is detachably connected to the connecting portion 122 of the locking component 120, so that the locking component 120 is fixed in the first groove 111 of the first shell 110. In this way, it can be ensured that the locking component 120 is fixed in the first groove 111 of the first shell 110 through the snap-fit ​​component 130.

[0098] like Fig.11As shown, in the embodiment of the present application, the clamping member 130 is provided with the following mutually spaced apart sides on one side of the bottom of the second groove 112: a first notch 1301, a second notch 1302 and a third notch 1303, the second notch 1302 is located between the first notch 1301 and the third notch 1303, a first elastic arm 131 is formed between the first notch 1301 and the second notch 1302, a second elastic arm 132 is formed between the second notch 1302 and the third notch 1303, and the first elastic arm 131 and the second elastic arm 132 are clamped at both ends of the connecting portion 122.

[0099] By sequentially arranging a first notch 1301, a second notch 1302 and a third notch 1303 spaced apart from each other on the snap-in component 130, a first elastic arm 131 is formed between the first notch 1301 and the second notch 1302, and a second elastic arm 132 is formed between the second notch 1302 and the third notch 1303. In this way, the first elastic arm 131 and the second elastic arm 132 are snapped at both ends of the connecting portion 122, thereby realizing a detachable connection between the snap-in component 130 and the connecting portion 122, and further realizing a detachable connection between the snap-in component 130 and the locking component 120.

[0100] In the embodiment of the present application, a first opening 1221 and a second opening 1222 are provided at both ends of the connecting portion 122 , the first elastic arm 131 is located in the first opening 1221 , and the second elastic arm 132 is located in the second opening 1222 , so as to clamp the connecting member 130 on the connecting portion 122 .

[0101] By providing the first opening 1221 and the second opening 1222 at both ends of the connecting portion 122, when the first elastic arm 131 and the second elastic arm 132 are clamped at the two ends of the connecting portion 122, the first elastic arm 131 is located in the first opening 1221, and the second elastic arm 132 is located in the second opening 1222. In this way, the first opening 1221 can assist in limiting and fixing the first elastic arm 131, and the second opening 1222 can assist in limiting and fixing the second elastic arm 132, so that the structural stability of the clamping member 130 when it is clamped on the connecting portion 122 is better.

[0102] In the embodiment of the present application, the first elastic arm 131 may include a first end and a second end relative to each other, wherein the first end 1311 of the first elastic arm is an end of the first elastic arm 131 close to the bottom of the second groove 112, and the second end 1312 of the first elastic arm is an end of the first elastic arm 131 away from the bottom of the second groove 112, and the second elastic arm 132 may include a first end and a second end relative to each other, the first end 1321 of the second elastic arm is an end of the second elastic arm 132 close to the bottom of the second groove 112, and the second end 1322 of the second elastic arm is an end of the second elastic arm 132 away from the bottom of the second groove 112, and the distance between the first end 1311 of the first elastic arm and the first end 1321 of the second elastic arm is smaller than the distance between the second end 1312 of the first elastic arm and the second end 1322 of the second elastic arm.

[0103] The distance between one end of the first elastic arm 131 close to the bottom of the second groove 112 and one end of the second elastic arm 132 close to the bottom of the second groove 112 is smaller than the distance between one end of the first elastic arm 131 away from the bottom of the second groove 112 and one end of the second elastic arm 132 away from the bottom of the second groove 112. In this way, the first elastic arm 131 and the second elastic arm 132 of the clamping member 130 form an inverted structure facing the bottom of the second groove 112. The first elastic arm 131 and the second elastic arm 132 of the clamping member 130 are in an inverted structure facing the bottom of the second groove 112. When 32 is clamped on the two ends of the connecting portion 122 of the locking component 120, the first end 1311 of the first elastic arm and the first end 1321 of the second elastic arm grab the two ends of the connecting portion 122. Therefore, the inverted structure design can make the connection between the first elastic arm 131 and the second elastic arm 132 and the two ends of the connecting portion 122 more tightly, avoiding separation between the clamping component 130 and the connecting portion 122 of the locking component 120, thereby avoiding the locking component 120 from being detached from the first groove 111 of the first shell 110.

[0104] It should be noted that, in the embodiment of the present application, the specific configuration of the first elastic arm 131 and the second elastic arm 132 may include but is not limited to the following two possible implementations:

[0105] A possible implementation manner is: the first end 1311 of the first elastic arm may be inclined toward the second elastic arm 132 , and the first end 1321 of the second elastic arm may be inclined toward the first elastic arm 131 .

[0106] The first end 1311 of the first elastic arm is inclined toward the second elastic arm 132, and the first end 1321 of the second elastic arm is inclined toward the first elastic arm 131, so as to ensure that the distance between the end of the first elastic arm 131 close to the bottom of the second groove 112 and the end of the second elastic arm 132 close to the bottom of the second groove 112 is smaller than the distance between the end of the first elastic arm 131 away from the bottom of the second groove 112 and the end of the second elastic arm 132 away from the bottom of the second groove 112, so that the first elastic arm 131 and the second elastic arm 132 of the clamping member 130 form an inverted structure facing the bottom of the second groove 112.

[0107] Another possible implementation is that a dimension of the first end 1311 of the first elastic arm in the length direction of the clamping member 130 may be greater than a dimension of the first end 1321 of the second elastic arm in the length direction of the clamping member 130 .

[0108] The dimension of the first end 1311 of the first elastic arm in the length direction of the clamp 130 is greater than the dimension of the first end 1321 of the second elastic arm in the length direction of the clamp 130, which can ensure that the distance between the end of the first elastic arm 131 close to the bottom of the second groove 112 and the end of the second elastic arm 132 close to the bottom of the second groove 112 is smaller than the distance between the end of the first elastic arm 131 away from the bottom of the second groove 112 and the end of the second elastic arm 132 away from the bottom of the second groove 112, so that the first elastic arm 131 and the second elastic arm 132 of the clamp 130 form an inverted structure facing the bottom of the second groove 112.

[0109] In addition, it should be noted that in the embodiment of the present application, the locking member 120 can also be as follows: Fig.12 The structure of the locking portion 121 in the locking member 120 is similar to Figure 8 and Fig. 9 As for the connection portion 122, refer to Fig.13 As shown, a third opening 1224 is provided in the middle of the connecting portion 122 , and the opening 1224 has a first inner wall 1224 a and a second inner wall 1224 b opposite to each other.

[0110] At this time, correspondingly, the first elastic arm 131 and the second elastic arm 132 are both located in the third opening 1224 , the first elastic arm 131 abuts against the first inner wall 1224 a , and the second elastic arm 132 abuts against the second inner wall 1224 b , so as to clamp the connector 130 on the connecting portion 122 .

[0111] Specifically, refer to Fig.13As shown, the first end 1311 of the first elastic arm forms a first buckling portion 1311a, which extends toward the first notch 1301 , and the first end 1321 of the second elastic arm forms a second buckling portion 1321a, which extends toward the third notch 1303 .

[0112] In addition, it can be understood that in the embodiment of the present application, a plurality of protrusions 1223 may be provided on a side of the connecting portion 122 facing away from the locking portion 121 , and the protrusions 1223 abut against the inner wall of the second recess 1112 .

[0113] By providing a plurality of protrusions 1223 on the side of the connecting portion 122 facing away from the locking portion 121, since the connecting portion 122 of the locking component 120 is located in the second recess 1112 of the first groove 111, the plurality of protrusions 1223 can abut against the inner wall of the second recess 1112. In this way, the plurality of protrusions 1223 of the connecting portion 122 and the inner wall of the second recess 1112 have an interference fit, which can make the connection tightness between the connecting portion 122 and the inner wall of the second recess 1112 better, thereby further preventing the connecting portion 122 of the locking component 120 from detaching from the second recess 1112 of the first groove 111.

[0114] Specifically, in the embodiments of the present application, refer to Fig.14 and Fig.15 As shown, the first groove 111 may include: a first recess 1111 and a second recess 1112 connected to the first recess 1111, and the second recess 1112 is also connected to the second groove 112, wherein, with reference to Fig.16 and Fig.17 As shown, the locking portion 121 is located in the first recess 1111 , and the connecting portion 122 is located in the second recess 1112 , so that the clamping member 130 and the connecting portion 122 are detachably connected.

[0115] By designing the first groove 111 to include a first recess 1111 and a second recess 1112 that are connected, the locking portion 121 of the locking component 120 is located in the first recess 1111, the connecting portion 122 of the locking component 120 is located in the second recess 1112, and the second recess 1112 is also connected to the second groove 112. The snap-fit ​​component 130 located in the second groove 112 is detachably connected to the connecting portion 122 located in the second recess 1112, so that the snap-fit ​​component 130 can fix the locking component 120 in the first groove 111 of the first shell 110.

[0116] In the embodiment of the present application, the extension direction of the second recess 1112 may be perpendicular to the extension direction of the second groove 112 .

[0117] By designing the extension direction of the second recess 1112 of the first groove 111 and the extension direction of the second groove 112 to be perpendicular to each other, the connecting portion 122 of the locking member 120 is located in the second recess 1112 of the first groove 111, and the snap-fit ​​member 130 is located in the second recess 112. Since the second recess 1112 is communicated with the second groove 112, when the snap-fit ​​member 130 located in the second groove 112 cooperates with the connecting portion 122 located in the second recess 1112, the vertically matched connection reliability is high and it is easy to implement the structural design.

[0118] It should be noted that in some embodiments, the second groove 112 may extend along the thickness direction of the electronic device 200 to the second recess 1112 of the first groove 111, and be flush with the lower side wall of the second recess 1112. Alternatively, in some other embodiments, the second groove 112 may extend along the thickness direction of the electronic device 200 to the second recess 1112 lower than the first groove 111, and be Fig.15 and Fig.17 Specifically, Fig.17 In the embodiment, the clamping member 130 is located in the second groove 112 , and one end of the clamping member 130 close to the bottom wall of the second groove 112 is lower than the lower side wall of the second recess 1112 .

[0119] It is easy to understand that in the actual assembly process, the locking component 120 is first placed in the first groove 111 of the first shell 110. The first shell 110 will constrain the locking component 120's freedom in the x+ direction, z direction and y direction. At the same time, the inner wall of the first groove 111 also constrains the locking component 120's rotational freedom in the x direction, z direction and y direction. Then, the snap-in component 130 is snapped into the buckling position of the locking component 120 through the second groove 112 of the first shell 110, and the first elastic arm 131 and the second elastic arm 132 of the snap-in component 130 limit the locking component 120 in the x+ direction. At this time, all the degrees of freedom of the locking component 120 have been constrained and will not fall out. The snap-in component 130 constrains its rotational degrees of freedom in the x, z and y directions through the first shell 110, and the second groove 112 of the first shell 110 constrains the rotational degrees of freedom of the snap-in component 130 in the x, z and y directions, thereby fixing the snap-in component 130, so that the three parts of the first shell 110, the locking component 120 and the snap-in component 130 form a tightly fitting whole that is not easy to fall out.

[0120] In the embodiment of the present application, the y direction is a direction perpendicular to both the x direction and the z direction. That is, the width direction of the electronic device 200 is the x direction, the thickness direction of the electronic device 200 is the z direction, and the y direction is the length direction of the electronic device 200.

[0121] In addition, in the embodiment of the present application, a locking position 1211 may be provided on a side of the locking portion 121 facing away from the connecting portion 122 .

[0122] A locking position 1211 is provided on a side of the locking portion 121 of the locking element 120 that is away from the connecting portion 122 . The locking position 1211 is used to be locked with a structure other than the connecting structure 100 on the electronic device 200 .

[0123] For example, in an embodiment of the present application, the electronic device 200 is a foldable electronic device 200, and the foldable electronic device 200 may include: a second shell 210, a hinge assembly 220 and a connecting structure 100. The second shell 210 is rotatably connected to the first shell 110 of the connecting structure 100 via the hinge assembly 220. A retractable lock tongue 2111 is provided on the second shell 210. Specifically, one end of the lock tongue 2111 is located in the second shell 210, and the other end of the lock tongue 2111 can be retracted into the second shell 210 or extended out of the second shell 210.

[0124] When the foldable electronic device is in the folded state, the other end of the locking tongue 2111 extends out of the second housing 210 and is engaged in the locking member 120 of the connection structure 100 to lock the first housing 110 and the second housing 210. When the first housing 110 and the second housing 210 are in the unfolded state, the other end of the locking tongue 2111 is located outside the second housing 210.

[0125] In this way, when the foldable electronic device 200 is in the folded state, that is, the first housing 110 and the second housing 210 are in the folded state, the locking tongue 2111 on the second housing 210 extends out of the second housing 210 and extends into the locking member 120 on the first housing 110. Specifically, the locking tongue 2111 extends into the locking position 1211 on the locking member 120 and cooperates with the locking position 1211, so that the first housing 110 and the second housing 210 are locked, so that the foldable electronic device 200 remains in the folded state. When the foldable electronic device 200 switches from the folded state to the unfolded state, the locking tongue 2111 on the second housing 210 shrinks into the second housing 210, and the locking tongue 2111 is separated from the locking member 120. Specifically, the locking tongue 2111 is separated from the locking position 1211 of the locking member 120, so that the first housing 110 and the second housing 210 are relatively unfolded. When the foldable electronic device is in the unfolded state, that is, when the first shell 110 and the second shell 210 are in the unfolded state, the other end of the locking tongue 2111 is located outside the second shell 210 .

[0126] In the embodiment of the present application, the locking member 120 may be a wear-resistant member with high hardness. When the locking member 120 is matched with the lock tongue 2111, the locking member 120 as a wear-resistant member can increase the service life of the locking member 120. Exemplarily, the material used for the locking member 120 may be Mylar. Mylar has the advantages of high insulation strength, high voltage resistance, resistance to moisture, gas, high heat and chemical substances, low shrinkage, not easy to be brittle and wear-resistant.

[0127] It should be noted that, in the embodiment of the present application, the material used for the locking member 120 may include but is not limited to the following two possible implementations:

[0128] One possible implementation is that the material used for the locking member 120 may be polycarbonate (PC). Polycarbonate has excellent properties such as high strength and elastic modulus, high impact strength, wide operating temperature range, high transparency and free dyeing, low molding shrinkage, good dimensional stability, good fatigue resistance, good weather resistance and excellent electrical properties.

[0129] Another possible implementation is that the material used for the locking member 120 may be polyethylene terephthalate (PET). Polyethylene terephthalate has excellent properties such as high tensile strength, low creep, excellent fatigue resistance, good wear resistance, good friction resistance, mechanical properties are less affected by temperature, good heat aging resistance and excellent electrical insulation.

[0130] In addition, it should be noted that the connection structure 100 provided in the embodiment of the present application can be applied to the electronic device 200 to achieve mechanical fixing and assembly between any spare parts and the first housing 110 or the second housing 210 of the electronic device 200. When the space of the electronic device 200 is limited or screws are not used, a connection method similar to that of the clamping member 130 located in the second groove 112 and the locking member 120 located in the first groove 111 can be used.

[0131] Specifically, when the clamping member 130 is matched with the locking member 120, the first elastic arm 131 and the second elastic arm 132 of the clamping member 130 are clamped at both ends of the connecting portion 122 of the locking member 120, forming a connection method similar to a mortise and tenon structure. This connection method has a small number of parts, saves space, is simple to assemble, has lower cost, and has good reliability. Therefore, the connection structure 100 provided in the embodiment of the present application can be used in any scenario where space limit of any size is required and reliable fixation is required.
