[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] In the following description, the X-axis direction represents the length direction of the spring piece 100 , the Y-axis direction represents the height direction of the spring piece 100 , and the Z-axis direction represents the width direction of the spring piece 100 .

[0029] The following describes a spring clip 100 according to an embodiment of the present invention, in conjunction with Figures 1-5 , comprising: a base 101, an elastic arm 102, and an electrical connection contact 103. The base 101 is used to securely connect to other components in an electronic device through welding, bonding, or the like, and serves as a patch receiving surface for the spring clip 100 during transport. As shown in Figure 2 , the fixed end 1021 of the elastic arm 102 is connected to the base 101, and the free end 1022 of the elastic arm 102 is bent toward the plane of the base 101, i.e., toward the negative Y-axis in Figure 2 , so that the elastic arm 102 has a curved portion 1023. The electrical connection contact 103 is protruding from the curved portion 1023 and bends with the curved portion 1023. The bending angle β of the curved portion 1023 is greater than 90 degrees. The advantage of this structure is that when the spring piece 100 is hit or scratched in a direction parallel to the elastic force arm 102, due to the existence of the bent portion 1023 and the obtuse angle design of the angle β, the impact and scratching force will be dispersed in the direction close to the base, and the elastic deformation ability of the elastic force arm 102 itself will be used to absorb the impact and scratching force, thereby avoiding the elastic force arm 102 from being bent and producing plastic deformation, and reducing the impact of scratches and impacts.

[0030] As shown in Figures 1, 2, and 3, according to some embodiments of the present invention, the base 101 includes a first support portion 1011 and a second support portion 1012. The second support portion 1012 and the elastic force arm 102 are disposed on the same side of the first support portion 1011. That is, as shown in Figure 2, the second support portion 1012 and the elastic force arm 102 both extend along the X-direction away from the first support portion 1011. One end 10121 of the second support portion is connected to the first support portion 1011, and the other end 10122 of the second support portion extends along the X-direction away from the first support portion 1011. A fixed end 1021 of the elastic force arm 102 is connected to the first support portion 1011, and the orthographic projection of the free end 1022 of the elastic force arm 102 on the plane of the base 101 is away from the first support portion 1011 along the X-direction. The advantage of this structure is that the arrangement of the first support portion 1011 and the second support portion 1012 stabilizes and supports the center of gravity of the spring clip 100. The second support portion 1012 can act as a reverse support arm when the elastic arm 102 is under pressure, preventing the welding surface from being subjected to leverage and causing the welding position to fail and fall off. Furthermore, the first support portion 1011 and the second support portion 1012 can also serve as patch suction surfaces, facilitating automated production. This structure is particularly suitable for reducing the Y-dimensional dimension of the spring clip 100. When layout space is limited, the entire spring clip 100 can rely on the structural design in the X-direction to reduce the Y-dimensional requirement.

[0031] As shown in Figures 1 and 3, according to some embodiments of the present invention, the elastic force arm 102 includes a first connecting arm 1024 and a second connecting arm 1025. The base 101 includes a first supporting portion 1011, the first supporting portion 1011 having a first connecting portion 10111, a spacer 10113, and a second connecting portion 10112. The first end 10211 of the first connecting arm is connected to the first connecting portion 10111, the first end 10212 of the second connecting arm is connected to the second connecting portion 10112, and the second end 10241 of the first connecting arm is connected to the second end 10251 of the second connecting arm and is bent toward the plane of the base 101 to form the bent portion 1023. The spacer 10113 is located between the first connecting portion 10111 and the second connecting portion 10112. As shown in Figure 3, the orthographic projection of the electrical connection contact 103 on the plane of the base 101 is opposite the spacer 10113. The advantage of this structure is that the first connecting arm 1024, the second connecting arm 1025 and the first supporting portion 1011 form a spatial triangle. The first connecting arm 1024 and the second connecting arm 1025 can support each other. The electrical connection contact 103, the first connecting portion 10111 and the second connecting portion 10112 constitute the three vertices of the triangle, and the structure of the entire shrapnel 100 is more stable.

[0032] As shown in Figures 1, 2, and 3, according to some embodiments of the present invention, the base 101 includes a first support portion 1011 and a second support portion 1012. The first connecting arm 1024, the second connecting arm 1025, and the second support portion 1012 are all located on the same side of the first support portion 1011. That is, as shown in Figure 3, the second support portion 1012 and the first and second connecting arms 1024, 1025 all extend along the X-direction away from the first support portion 1011. One end 10121 of the second support portion is connected to the spacer 10113, and the other end 10122 of the second support portion extends away from the first support portion 1011. As shown in Figures 1 and 3, the orthographic projections of the first and second connecting arms 1024, 1025 on the plane of the base 101 and the first support portion 1011 enclose a closed annular structure 104, and the second support portion 1012 is at least partially located within the closed annular structure 104. The advantage of this structure is that the arrangement of the first support portion 1011 and the second support portion 1012 stabilizes and supports the center of gravity of the shrapnel 100. The second support portion 1012 and the first connecting arm 1024 and the second connecting arm 1025 are located on the same side of the first support portion 1011. Therefore, when the first connecting arm 1024 and the second connecting arm 1025 are under pressure, they can serve as a reverse support arm to prevent the welding surface from being subjected to the lever force and causing the welding position to fail and fall off. In addition, the first support portion 1011 and the second support portion 1012 can also serve as patch suction surfaces, facilitating automated production. This structure is particularly suitable for reducing the Y-direction dimension of the shrapnel 100. When the layout space is limited, the entire shrapnel 100 can rely on the structural design in the X direction to reduce the Y-direction dimension requirement. The first connecting arm 1024, the second connecting arm 1025 and the first support portion 1011 form a closed ring structure 104, making the structure of the entire shrapnel 100 more stable. The second support portion 1012 is at least partially located within the closed annular structure 104. This ensures that no matter whether the spring piece 100 is subjected to X-direction collision force, Y-direction pressure or Z-direction collision force, after the force is transmitted toward the first connecting arm 1024 and the second connecting arm 1025, the second support portion 1012 can play a role in improving stability within the annular structure 104.

[0033] As shown in Figures 2 and 3, according to some embodiments of the present invention, the second support portion 1012 is located between the first support portion 1011 and the bent portion 1023. As shown more clearly in Figure 3, the other end 10122 of the second support portion is opposite to the orthographic projection of the electrical connection contact 103 on the plane where the base 101 is located. In other words, the other end 10122 of the second support portion and the orthographic projection of the electrical connection contact 103 on the plane where the base 101 is located are on the same straight line in the X direction. The advantage of this structure is that in the X direction, the external force exerted on the electrical connection contact 103 can be symmetrically transmitted to the second support portion 1012 via the first connecting arm 1024 and the second connecting arm 1025, so that the second support portion 1012 can achieve a better stabilization effect. The second support portion 1012 acts as a reverse force arm and can reduce the size and space requirements of the spring.

[0034] As shown in Figures 1 and 3, according to some embodiments of the present invention, the first connecting arm 1024 includes a first connecting segment 10242 extending toward the electrical connection contact 103, and the second connecting arm 1025 includes a second connecting segment 10252 extending toward the electrical connection contact 103. The first connecting segment 10242 and the second connecting segment 10252 are connected and bent toward the plane of the base 101 to form the curved portion 1023. As shown in Figure 3, the angle δ between the first connecting segment 10242 and the second connecting segment 10252 is less than 135° and greater than 60°. In other words, a triangular structure is formed at the curved portion 1023. The advantage of this structure is that the electrical connection contact 103, which is the point most susceptible to collision and stress, is more stable due to the triangular structure of the curved portion 1023, thereby providing better stress resistance.

[0035] As shown in Figures 1 and 3, according to some embodiments of the present invention, the first connecting arm 1024 further includes a first parallel section 10243, one end of which is connected to the first connecting portion 10111, and the other end of which is connected to the first connecting section 10242. The second connecting arm 1025 further includes a second parallel section 10253, one end of which is connected to the second connecting portion 10112, and the other end of which is connected to the second connecting section 10252. The first parallel section 10243 is parallel to the second parallel section 10253. This structure has the advantage of evenly distributing force on both sides of the spring clip 100, preventing the spring clip 100 from tipping over during force application or transportation. According to other embodiments of the present invention, the first connecting arm 1024 and the second connecting arm 1025 are symmetrically arranged in structure, for example, the two are arranged in an "eight" shape, or the two are arranged in a symmetrical "S" shape, both of which can balance the force on both sides of the shrapnel 100 and prevent the shrapnel 100 from tipping over during the force or transportation process.

[0036] As shown in Figures 3 and 4, according to some embodiments of the present invention, the side of the first connecting segment 10242 facing away from the second connecting segment 10252 serves as a first anti-collision side 10244. The first anti-collision side 10244 has a first recess 10245 that is recessed toward the electrical connection contact 103. This structure has the advantage that when the first connecting arm 1024 is impacted by a lateral external force F2, F2 can be dispersed toward the first recess 10245 and then borne by the electrical connection contact 103. The electrical connection contact 103, as the strongest point in the curved portion 1023, has a greater force-bearing capacity. Optionally, the side of the second connecting segment 10252 facing away from the first connecting segment 10242 serves as a second anti-collision side 10254. The second anti-collision side 10254 has a second recess 10255 that is recessed toward the electrical connection contact 103. The advantages of this structure are similar to those of the first recess 10245 and will not be further described. The first recess 10245 and the second recess 10255 can exist independently or simultaneously. When independently, they can improve the single-sided force-bearing capacity of the elastic force arm 102. When they exist simultaneously, they can improve the double-sided force-bearing capacity of the elastic force arm 102.

[0037] According to other embodiments of the present invention, the elastic arm 102 has a first anti-collision side surface 10244 connected between the fixed end 1021 and the free end 1022 of the elastic arm 102. The first anti-collision side surface 10244 has a first recess 10245 that is recessed toward the electrical connection contact 103. In this embodiment, the first anti-collision side surface 10244 extends from the fixed end 1021 to the free end 1022, thereby dispersing the side collision force F2 over a wider range and dispersing F2 toward the electrical connection contact 103 via the first recess 10245.

[0038] As shown in Figures 2, 3, 4, and 5, the electrical connection contact 103 is protruding from the side of the curved portion 1023 facing away from the base 101, that is, the electrical connection contact 103 extends upward in the Y direction as shown in Figure 5. The line connecting the orthographic projection of the vertex 1031 of the electrical connection contact 103 on the side facing away from the base 101 and the orthographic projection of the bottom of the first recess 10245 on the same plane forms the first bend line 1032. The portion of the elastic arm 102 between the first bend line 1032 and the base 101 extends away from the plane of the base 101, that is, has an upward component in the Y direction, thereby forming an angle α between the elastic arm 102 and the base 101. The portion of the elastic arm 102 between the first bend line 1032 and the free end 1022 extends toward the plane of the base 101, that is, has a downward component in the Y direction. This structure can reduce the impact of side impact on the electrical connection stability of the electrical connection contact 103. That is, during a side impact, even if the elastic force arm 102 undergoes elastic deformation, it can still ensure that the electrical connection contact 103 is in contact with the surrounding electronic components.

[0039] As shown in Figures 1, 2, 3, and 4, according to some embodiments of the present invention, the electrical connection contact 103 is positioned across the curved portion 1023 and extends toward the end surface of the free end 1022 of the elastic arm 102. This provides the electrical connection contact 103 with a wider electrical contact area. The portion of the electrical connection contact 103 of the elastic arm 102, between the vertex 1031 on the side facing away from the base 101 and the end surface of the free end 1022, forms a guide connecting segment 1027. At least one of the two opposing side surfaces of the guide connecting segment 1027 is provided with a curved protrusion 1026. One end of the curved protrusion 1026 extends to the first bend line 1032, and the other end of the curved protrusion 1026 extends to the end surface of the free end 1022 of the elastic arm 102. The curved protrusion 1026 protrudes from the side surface of the guide connecting segment 1027, away from the electrical connection contact. The curved convex portion 1026 further helps to disperse the lateral pressure exerted on the free end of the elastic arm 102, reducing the impact of the lateral pressure exerted on the free end of the elastic arm 102 on the electrical connection contact 103 due to the larger arm. The function of the curved convex portion 1026 is to disperse the lateral external force exerted on the free end of the elastic arm 102 toward the curved portion 1023 to minimize the impact. The design of the curved convex portion also further prevents the force point from falling within the first recess, effectively reducing the impact of lateral pressure on the electrical connection contact.

[0040] As shown in Figures 2, 4 and 5, according to some embodiments of the present invention, a first guide slope 10246 is provided between the first anti-collision side 10244 and the surface of the elastic force arm 102 facing away from the plane where the base 101 is located; and / or a second guide slope 10247 is provided between the first anti-collision side 10244 and the surface of the elastic force arm 102 facing and toward the plane where the base 101 is located; and / or a third guide slope 10221 is provided between the end surface of the free end 1022 of the elastic force arm 102 and the surface of the elastic force arm 102 facing away from the plane where the base 101 is located; and / or a fourth guide slope 10222 is provided between the end surface of the free end 1022 of the elastic force arm 102 and the surface of the elastic force arm 102 facing the plane where the base 101 is located. The spring piece 100 has at least one of the first guiding bevel 10246, the second guiding bevel 10247, the third guiding bevel 10221, and the fourth guiding bevel 10222. The first guiding bevel 10246 and the second guiding bevel 10247 can not only remove burrs and prevent scratching of surrounding components, but also disperse the Z-direction collision force F2 as shown in Figure 4 further in the upper and lower directions of the Y direction. The first guiding bevel 10246 and the second guiding bevel 10247 can intersect, or there can be a distance H between the two bevels. The function of the third guiding bevel 10221 is to disperse the X-direction collision force F1 obliquely upward along the Y direction, and the function of the fourth guiding bevel 10222 is to disperse the X-direction collision force F1 obliquely downward along the Y direction. The third guiding bevel 10221 and the fourth guiding bevel 10222 also have the function of removing burrs and preventing scratching. As shown in Figure 2, the third guide slope 10221 forms an obtuse angle γ with the bending direction of the free end 1022 (i.e., the dotted line in Figure 2). Similarly, the fourth guide slope 10222 also forms an obtuse angle (not shown) with the bending direction of the free end 1022, thereby forming a guide slope.

[0041] As shown in FIG4 , the portion between the vertex 1031 of the electrical connection contact 103 of the elastic arm 102, facing away from the base 101, and the end surface of the free end 1022, constitutes the guide connecting segment 1027. In the direction approaching the end surface of the free end 1022 of the elastic arm 102, the distance between the two opposing sides of the guide connecting segment 1027 is equal. However, in other embodiments of the present invention, the distance between the two opposing sides of the guide connecting segment 1027 gradually decreases, forming a triangular structure, thereby making the guide connecting segment 1027 more stable. As shown in FIG4 , the two opposing sides of the guide connecting segment 1027 (i.e., the sides where the two curved protrusions 1026 are located) are connected between the surface of the guide connecting segment 1027 facing the base 101 and the surface of the guide connecting segment 1027 facing away from the base 101. In other words, the guide connecting section 1027 also forms a triangular structure near the free end 1022, thereby further strengthening the local structure. Furthermore, the distance between the two opposing sides of the guide connecting section 1027 gradually decreases, and the resulting triangular structure of the guide connecting section 1027 can effectively disperse the lateral pressure F2 applied to the side surfaces of the guide connecting section 1027. For details, please refer to the schematic diagram of the guide connecting section 1027 dispersing the lateral pressure F2 indicated by the dotted arrows in Figures 3 and 4.

[0042] As shown in Figures 6, 7, 8 and 9, according to some other embodiments of the present invention, the elastic force arm 102 includes a first force arm portion 1028 and a second force arm portion 1029, the fixed end 1021 of the elastic force arm 102 is the first end of the first force arm portion 1028, the free end 1022 of the elastic force arm 102 is the second end of the second force arm portion 1029, the second end of the first force arm portion 1028 and the first end of the second force arm portion 1029 are connected to form the bending portion 1023; the angle between the first force arm portion 1028 and the second force arm portion 1029 is the bending angle β of the bending portion 1023. Similar to the embodiment shown in Figure 2, the bending angle β is also an obtuse angle greater than 90 degrees. When the spring piece 100 is hit or scratched in a direction parallel to the elastic force arm 102, due to the existence of the bent portion 1023 and the obtuse angle design of the angle β, the impact or scratching force will be dispersed in the direction close to the base, and the elastic deformation ability of the elastic force arm 102 itself will be used to absorb the impact or scratching force, thereby avoiding the elastic force arm 102 from being bent and producing plastic deformation, and reducing the impact of scratches and impacts.

[0043] As shown in Figures 6, 7, 8, and 9, the spring clip 100 further includes a stopper 105 for limiting the movement of the second end (i.e., the free end 1022) of the second lever portion 1029. The stopper 105 prevents the electrical connection contact 103 from bouncing up and down excessively, thereby causing a loose connection between the base 101 and other components. The weight of the stopper 105 can also be used to stabilize the center of gravity of the spring clip 100.

[0044] The base 101 includes a first support portion 1011 and a second support portion 1012. The second support portion 1012 and the elastic force arm 102 are disposed on the same side of the first support portion 1011. That is, as shown in FIG7 , the second support portion 1012 and the elastic force arm 102 both extend along the X-direction toward a side away from the first support portion 1011. A first spacing space 106 exists between the second support portion 1012 and the elastic force arm 102. The first force arm portion 1028 is connected to the first support portion 1011. One end of the second support portion 1012 is connected to the first support portion 1011, and the other end of the second support portion 1012 extends toward a direction away from the first support portion 1011. A stopper 105 is provided at the other end of the second support portion 1012 to limit the movement of the second end (i.e., the free end 1022) of the second force arm portion 1029. The first support portion 1011 and the second support portion 1012 are coplanar, so the second support portion 1012 can be fixedly connected to other components together with the first support portion 1011, and the patch suction area can be increased during transportation. The limit portion 105 is located at an end away from the first support portion 1011. The weight of the elastic force arm 102 between the first support portion 1011 and the limit portion 105 can be well supported by the limit portion 105 and the first support portion 1011, and the external force applied to the elastic force arm 102 can also be decomposed by the limit portion 105 and the first support portion 1011.

[0045] The limiting portion 105 includes a connecting structure 1051 and a limiting structure 1052. The connecting structure 1051 is connected to the base 101, and the limiting structure 1052 is connected to the connecting structure 1051. The limiting structure 1052 extends to face at least one side of the second lever portion 1029 to limit the movement of the second end (i.e., the free end 1022) of the second lever portion 1029. More specifically, as shown in FIG8 , the limiting structure 1052 faces the first connecting side surface 10291 and / or the second connecting side surface 10292 of the second lever portion 1029, thereby limiting the movement of the elastic lever 102 in the Z direction, thereby preventing excessive movement of the elastic lever in the Z direction from causing plastic deformation and affecting the connection reliability of the electrical connection contact 103.

[0046] As shown in Figures 8 and 9, the limiting structure 1052 includes a first limiting section 10521, a second limiting section 10522, a third limiting section 10523 and a fourth limiting section 10524; one end of the first limiting section 10521 is connected to the connecting structure 1051, and the other end of the first limiting section 10521 is connected to the second limiting section 10522, and the first limiting section 10521 is opposite to the first connecting side surface 10291 of the second force arm portion 1029; the end of the second limiting section 10522 away from the first limiting section 10521 is connected to the The third limiting section 10523 is connected, and the second limiting section 10522 is opposite to the surface of the second force arm part 1029 facing away from the base 101 (i.e., the upper surface in the Y direction in Figure 8); the end of the third limiting section 10523 away from the second limiting section 10522 is connected to the fourth limiting section 10524, and the third limiting section 10523 is opposite to the second connecting side surface 10292 of the second force arm part 1029; the end of the fourth limiting section 10524 away from the third limiting section 10523 is opposite to the connecting structure 1051. A second spacing space 10526 exists between the fourth limiting section 10524 and the connecting structure 1051. The presence of the second spacing space 10526 ensures that if the elastic arm 102 strikes the limiting portion, causing the fourth limiting section 10524 to form a virtual connection with the mounting surface of the electronic device, this virtual connection will not spread to the connecting structure 1051, thereby still ensuring the reliability of the connection between the spring 100 and other components. The fourth limiting section 10524 is opposite to the surface of the second arm portion 1029 that is close to the base 101 (i.e., the lower surface of the second arm portion 1029 in the Y direction as shown in FIG8 ); the first connecting side surface 10291 and the second connecting side surface 10292 are two opposing side surfaces of the second arm portion 1029, and are respectively connected between the surface of the second arm portion 1029 that is away from the base 101 and the surface of the second arm portion 1029 that is close to the base 101. In this way, as shown in Figure 8, the first connecting side 10291, the second connecting side 10292, and the upper surface and lower surface of the second force arm part 1029 can all be restricted by the limiting structure 1052. After the up and down jumping of the elastic force arm 102 in the Y direction and the left and right movement in the Z direction are restricted, the elastic force arm 102 is not easy to deform.

[0047] As shown in FIG7 , when the spring is in a free state, the orthographic projection of the end surface of the second end of the second lever portion 1029 (i.e., the free end 1022) on the plane of the base 101 does not exceed the orthographic projection of the fourth limiting segment 10524 on the plane of the base 101, and / or the orthographic projection of the end surface of the second end of the second lever portion 1029 on the plane of the base 101 does not exceed the orthographic projection of the second limiting segment 10522 on the plane of the base 101. In other words, in the X direction, the free end 1022 of the second lever portion 1029 does not extend beyond the limiting structure 1052, thereby preventing the free end 1022 from being subjected to external collisions.

[0048] As shown in FIG8 , when the limiting structure 1052 extends to face the surface of the second lever portion 1029 proximal to the base 101, the limiting section of the limiting structure 1052 that faces the surface of the second lever portion 1029 proximal to the base 101 (i.e., the lower surface of the free end 1022 in the Y direction in FIG8 ) (i.e., the fourth limiting section 10524) is coplanar with the connecting structure 1051. Thus, the base 101, the connecting structure 1051, and the fourth limiting section 10524 are coplanar, and the fourth limiting section 10524 not only serves as a limiter but also, together with the base 101 and the connecting structure 1051, can be fixedly connected to other components, thereby improving the connection stability between the spring piece 100 and other components.

[0049] As shown in FIG9 , a first guide angle 10525 is provided on the edge of the end surface of the limiting structure 1052 facing the first lever portion 1028. When the spring piece 100 is under pressure, the second lever portion 1029 is pressed and moves relative to the limiting structure 1052. The first guide angle 10525 guides the movement of the second lever portion 1029. And / or, as shown in FIG8 , a second guide angle 10293 is provided on the edge of the end surface of the second end (i.e., the free end 1022) of the second lever portion 1029. The second guide angle 10293 prevents the free end 1022 from scratching the limiting structure 1052 during movement. And / or, as shown in Figure 8, when the spring piece 100 is in a free state, the second end of the second force arm portion 1029 (i.e., the free end 1022) and the various limiting segments of the limiting structure 1052, including the first limiting segment 10521, the second limiting segment 10522, the third limiting segment 10523 and the fourth limiting segment 10524 are all spaced apart, thereby providing space for the movement of the free end 1022. After the spring piece 100 is connected to other components, it can have a certain amount of room for movement during the force-bearing process.

[0050] According to some embodiments of the present invention, an electronic device is further provided, comprising the spring clip 100 as described in any of the preceding items. Optionally, the electronic device further comprises a mounting portion and an electrical connector, wherein the mounting portion comprises a mounting surface, and the base 101 of the spring clip 100 is fixed to the mounting surface by welding, bonding, or the like; the electrical connector is opposite to the mounting surface, and the electrical connector presses the electrical connection contact 103 toward the base 101 to achieve electrical connection with the spring clip 100.

[0051] The electronic device of the embodiment of the present invention adapts to the design of the smaller Y-height of the spring 100 , and the spatial layout can be more compact. In addition, the spring 100 can obtain good anti-collision and anti-scratch performance.

[0052] The spring piece 100 is preferably made of an elastic conductive material as a whole. Different parts may also be made of different materials as needed, as long as the elastic force arm 102 is elastic.
