Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a metal spring and an electronic equipment. Background Art

[0002] For electronic devices such as mobile phones, metal shrapnel is often used to connect the circuit board with the RF antenna. The commonly used metal shrapnel structure currently has an elastic arm in only one direction. With the continuous development of electronic technology, various electronic devices have emerged. When a certain RF antenna is composed of two shells that are perpendicular to each other, the metal shrapnel with an elastic arm in a single direction cannot meet the connection requirements. The current solution is to use a metal shrapnel crimped in the horizontal direction and a metal shrapnel crimped in the vertical direction to be set on the circuit board, and respectively connected to the two shells that are perpendicular to each other of the RF antenna. However, this solution leads to an increase in the number of metal shrapnel on the circuit board, and the spatial layout of electronic equipment becomes increasingly compact. The increase in the number of metal shrapnel can easily lead to longer paths, greater antenna signal loss, and poor consistency in contact stability. Utility Model Content

[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0028] Example 1

[0029] The present application embodiment provides a metal spring, such as Figures 1 to 5 As shown, it includes: a main body 1, the main body 1 has a first connecting end and a second connecting end; a first elastic arm 2, connected to the first connecting end; a second elastic arm 3, connected to the second connecting end; the first elastic arm 2 and the second elastic arm 3 meet a first angle condition.

[0030] The metal spring provided in the embodiment of the present application can be used to provide reliable electrical contact or mechanical support functions, and is particularly suitable for application scenarios that require stable elastic force in a limited space, such as connectors, antennas, battery contact sheets, etc. in electronic devices.

[0031] The body 1 of the metal shrapnel can be made of metal materials (such as stainless steel, copper alloy, etc.) to ensure good conductivity and durability. The shape of the body 1 can be a strip, U-shaped or other geometric shapes suitable for a specific application, which is used to provide a stable base. The body 1 has a first connection end and a second connection end, the first connection end is connected to the second elastic arm 3, the second connection end is connected to the second elastic arm 3, and the first elastic arm 2 and the second elastic arm 3 can have a moderate curvature or a preformed elastic curve, so that the expected elastic deformation can be generated when the force is applied, and the original state can be restored after the external force is removed. By having a first angle between the first elastic arm 2 and the second elastic arm 3, it is possible to achieve accurate docking and stable connection of two components with angles in the target structure. For example, when a certain radio frequency antenna is composed of two vertical metal bodies, the metal shrapnel provided in the embodiment of the present application can be respectively abutted with the two metal bodies, thereby not only ensuring that the signal conduction path between the two metal bodies is the shortest, but also effectively reducing the use of additional metal shrapnel, thereby reducing the signal loss of the antenna system and improving the transmission efficiency.

[0032] The metal spring provided in the embodiment of the present application integrates a first elastic arm 2 and a second elastic arm 3 with an angle on a main body 1. While achieving precise abutment of two components with an angle in the target structure, it optimizes space utilization and can provide necessary elastic functions in a small space, which is suitable for application environments with limited space.

[0033] In some embodiments, the main body 1 includes a first part 101 and a second part 102, and the first part 101 and the second part 102 satisfy a second angle condition to form adjacent first installation space and second installation space; the first elastic arm 2 is placed in the first installation space, and the second elastic arm 3 is placed in the second installation space.

[0034] The body 1 includes a first part 101 and a second part 102, and a specific second angle condition is formed between the two parts, dividing the first installation space and the second installation space. The first elastic arm 2 is placed in the first installation space to ensure that it can effectively contact a component in the target structure and provide the necessary elastic force; similarly, the second elastic arm 3 is configured in the second installation space and can be connected to another component in the target structure. By embedding the first elastic arm 2 and the second elastic arm 3 in two spaces respectively, not only the overall stability of the metal shrapnel is guaranteed, but also each elastic arm can work independently without interfering with each other, thereby improving the flexibility and reliability of the connection.

[0035] In some embodiments, Figure 5 As shown, the first elastic arm 2 is vertically arranged with respect to the first part 101, and the first elastic arm 2 includes a first end 201 and a second end 202 opposite to each other, and the first end 201 is arranged toward the first part 101 and can abut against the first part 101; the second elastic arm 3 is vertically arranged with respect to the second part 102, and the second elastic arm 3 includes a third end 301 and a fourth end 302 opposite to each other, and the third end 301 is arranged toward the second part 102 and can abut against the second part 102.

[0036] Since the first part 101 and the second part 102 have a second angle, the first elastic arm 2 extending vertically from the first part 101 and the second elastic arm 3 extending vertically from the second part 102 can naturally form a corresponding angle layout, that is, the first angle, so that the two structural components with corresponding angles can be adapted to achieve precise docking. The first end 201 of the first elastic arm 2 is close to and can directly abut on the surface of the first part 101, so that when its second end 202 abuts against a component of the target structure and is subjected to force, the first elastic arm 2 deforms so that its first end 201 abuts against the first part 101. Similarly, when the second elastic arm 3 abuts against the fourth end 302 at another component of the target structure, its third end 301 can also be closely attached to and abut on the second part 102. Thereby, the metal spring piece stably connects the two structural components with corresponding angles.

[0037] In some embodiments, the first end 201 , the second end 202 , the third end 301 , and the fourth end 302 are respectively provided with contacts 4 .

[0038] The contact 4 can be formed at a designated position of the elastic arm by stamping, electroplating or other surface treatment processes, and the contact 4 can improve the electrical contact performance with the target structure or circuit. The design of the contact 4 can be a flat metal sheet, a bump, a gold-plated layer, etc., depending on the application requirements.

[0039] The contact 4 in the metal spring provided in the embodiment of the present application is arranged on the surface of the protruding elastic arm. By arranging a special contact 4 at the end of the elastic arm, the reliability and conductivity of the electrical contact are significantly enhanced, the contact resistance is reduced, the signal attenuation can be reduced, and the accuracy of data transmission is improved.

[0040] In some embodiments, two ends of the first portion 101 are respectively connected to the third portions 103 , and a pair of the third portions 103 are used to connect to the target module.

[0041] like Figure 3 As shown, the first part 101 may be a rectangular plate structure, and a pair of third parts 103 may be connected to the two ends along the length direction. The third part 103 may be designed as a flat plate structure to directly fit the target module, or may be formed into a specific angle with the first part 101 through a bending process to meet different types of connection requirements. For example, Figure 6 As shown, when the third part 103 adopts a bending design, a pair of third parts 103 and the first part 101 can be integrated to form a U-shaped structure, and a pair of through-hole structures can be preset on the target module (such as a circuit board), so that the third part 103 can pass through the through-hole structure, so that the metal spring can be stably connected to the target module. The third part 103 and the target module can be connected by welding, screw fixing, snap-on installation or other connection methods, and the pair of third parts 103 can establish a stable physical and / or electrical connection between the metal spring and the target module (such as a circuit board, a housing component or other electronic components).

[0042] In some embodiments, Figures 4 to 5 As shown, the body 1 further includes a fourth portion 104 , which is connected to the first portion 101 and is located in the same plane as the first portion 101 , and is used for communication connection with the target module.

[0043] The fourth portion 104 may be a straight extension extending from the first portion 101, or may be firmly connected to the first portion 101 by welding, bending, or other methods. The fourth portion 104 may include a specific communication interface, such as a precise conductive contact 4 formed by directly welding with a target module (such as a circuit board). Figure 6 As shown, seamless connection with the communication port of the target module is achieved to realize data transmission function. Through the fourth part 104 and the communication connection with the target module, the metal spring can not only provide elastic contact function, but also integrate the communication interface, realize the dual functions of mechanical connection and data / signal transmission, and improve the integration of the target module. The fourth part 104 and the first part 101 are located in the same plane, ensuring the precise alignment between the metal spring and the target module, and ensuring the consistency and stability of signal transmission.

[0044] In some embodiments, Figures 2 to 3 As shown, the main body 1 also includes: a fifth part 105, which is located in the first installation space and is opposite to the first part 101; a sixth part 106, which is located in the second installation space and is opposite to the second part 102; the first elastic arm 2 also includes a fifth end 203 located between the first end 201 and the second end 202, and the fifth end 203 is connected to the fifth part 105 through a first bending structure; the second elastic arm 3 also includes a sixth end 303 located between the third end 301 and the fourth end 302, and the sixth end 303 is connected to the sixth part 106 through a second bending structure; wherein the first part 101 is connected to the second part 102 at a right angle.

[0045] The first part 101 and the second part 102 are connected at a right angle, forming two opposite installation spaces, that is, the side of the first part 101 facing away from the second part 102 is the first installation space, and the side of the first part 101 facing the second part 102 is the second installation space. The fifth part 105 and the sixth part 106 are respectively arranged at the positions where the first installation space is opposite to the first part 101 and the second installation space is opposite to the second part 102, and together form a three-dimensional support frame similar to an S-shape. This design not only saves space, but also increases the overall stability. The first part 101, the second part 102, the fifth part 105 and the sixth part 106 can all be plate structures. The first part 101 is connected to the fifth part 105 through at least one bending structure, and the second part 102 is connected to the sixth part 106 through at least one bending structure.

[0046] The first elastic arm 2 and the second elastic arm 3 of the metal spring can be made of a plate structure through a bending process. Specifically, starting from the fifth end 203 (or the sixth end 303), it extends in one direction to the second end 202 (or the fourth end 302), then turns back and extends to the first end 201 (or the third end 301), and then turns back again to form a special shape of the elastic arm, and the contact 4 can be set at the bend of each elastic arm. By repeatedly bending, the elastic arm has sufficient elasticity, and it can also ensure that the force can be effectively transmitted and the shape memory can be maintained when subjected to force.

[0047] The fifth part 105 of the body 1 is connected to the fifth end 203 through a first bending structure, so that the first end 201 of the first elastic arm 2 can maintain a predetermined distance with the first part 101 and generate elastic force, and when the second end 202 is subjected to force, the first elastic arm 2 can be deformed so that the first end 201 abuts against the first part 101. Similarly, the sixth part 106 is connected to the sixth end 303 through a second bending structure, so that the third end 301 of the second elastic arm 3 maintains a predetermined distance with the second part 102 and generates elastic force, and when the fourth end 302 is subjected to force, the second elastic arm 3 can be deformed so that the third end 301 abuts against the second part 102.

[0048] In some embodiments, Figure 5 As shown, on both sides of the first elastic arm 2, the first part 101 is connected with a pair of first protective walls 107 arranged opposite to each other. Physical protection can be provided for the first elastic arm 2 to prevent the first elastic arm 2 from being damaged due to accidental collision or extrusion during installation, use or transportation. At the same time, the first protective wall 107 can also assist in positioning to ensure that the first elastic arm 2 moves on a predetermined path or position to avoid interference with other components. Similarly, the second part 102 can also be provided with a pair of second protective walls 108 arranged opposite to each other on both sides of the second elastic arm 3, which can protect the second elastic arm 3 from external physical damage, and by limiting its movement trajectory, ensure that the second elastic arm 3 is correctly in contact with the target structure, thereby improving the accuracy and reliability of assembly. The first part 101 can be used as one of the second protective walls 108, thereby improving the compactness of the overall structure of the metal shrapnel.

[0049] In some embodiments, Figure 2 and Figure 3 As shown, the side of the second protective wall 108 away from the second part 102 is bent and extended to form a third protective wall 109 parallel to the sixth part 106. The third protective wall 109 can cover the sixth part 106, providing an additional protective barrier for this area. The third protective wall 109 can enhance the protection of the more fragile or key protection area (such as the sixth part 106) in the metal shrapnel, and can effectively prevent damage to this part due to external physical impact, friction or foreign matter intrusion.

[0050] The metal spring provided in the embodiment of the present application can effectively dock with the target structure with an angle through the first angle between the first elastic arm 2 and the second elastic arm 3, forming the shortest connection path, reducing signal loss, and providing stable elastic support. Compared with the situation in which multiple single elastic arm springs are required to meet the angle docking in the traditional technology, the metal spring provided in the embodiment of the present application greatly reduces the number of springs required through the integrated double-arm design, which not only reduces the cost, but also makes more effective use of the limited internal space.

[0051] Example 2

[0052] The present application embodiment provides an electronic device, such as Figure 7As shown, it includes: a circuit board 100; an antenna, including a first metal body 200 and a second metal body 300, and the first metal body 200 and the second metal body 300 meet the third angle condition; a metal spring 400, including: a main body 1, the main body is connected to the circuit board 100, and has a first connecting end and a second connecting end; a first elastic arm 2, connected to the first connecting end, abutting against the first metal body 200; a second elastic arm 3, connected to the second connecting end, abutting against the second metal body 300; the first elastic arm 2 and the second elastic arm 3 meet the first angle condition.

[0053] As the core of the electronic device, the circuit board 100 carries various electronic components, including functional modules such as control, signal processing and power management. The antenna is composed of a first metal body 200 and a second metal body 300, which are arranged according to a third angle condition to adapt to specific frequency ranges or direction requirements, such as in multi-band operation, space-constrained or directional transmission / reception devices.

[0054] The body 1 of the metal shrapnel 400 is directly connected to the circuit board 100. The body 1, as the base of the metal shrapnel 400, can provide a stable installation point to ensure the reliability of electrical and mechanical connections. The first elastic arm 2 extends from the first connection end, and one end thereof can be tightly abutted against the first metal body 200, and maintains continuous contact pressure through elastic deformation to ensure good electrical conduction. Similarly, the second elastic arm 3 extends from the second connection end and abuts against the second metal body 300, forming an electrical connection that matches the second metal body 300, and together completes the signal transmission path between the antenna and the circuit board 100. The angle design between the first elastic arm 2 and the second elastic arm 3 can match the third angle condition of the antenna, ensuring efficient docking in a limited space, reducing the loss and impedance variation caused by the line on the circuit board 100, with less loss and more continuous impedance, which is conducive to improving antenna performance.

[0055] In some embodiments, Figure 6 As shown, a relief space is provided on the circuit board 100 , and the metal spring 400 is disposed in the relief space.

[0056] The avoidance space refers to an area reserved in the design layout of the circuit board 100 where no electronic components or circuits are arranged, and its size and shape can match the metal dome 400. A avoidance space is set on the circuit board 100 according to the size, shape and connection requirements of the metal dome 400 with the circuit board 100. For example, an opening can be cut on the circuit board 100, and the metal dome 400 is placed in this opening, so that the first elastic arm 2 and the second elastic arm 3 of the metal dome 400 are respectively located on both sides of the circuit board 100. This opening needs to ensure that the metal dome 400 will not conflict with the surrounding electronic components or wiring after installation, and will not affect other functional areas of the circuit board 100. The metal dome 400 is fixed by welding, screw fixing or specific plug-in interface to ensure that the metal dome 400 is both stable and easy to assemble.

[0057] Through the pre-planned avoidance space, the metal dome 400 with two elastic arms can be integrated into a position in the circuit board 100 without affecting other functional layouts of the circuit board 100, which helps to achieve miniaturization and high-density design of electronic equipment.

[0058] In some embodiments, the electronic device also includes: a shell, the shell including a frame and a back shell, the frame and the back shell are interconnected to form a cavity, and the circuit board 100 is arranged in the cavity; the first metal body 200 is arranged on the first surface of the frame facing the circuit board 100, and the second metal body 300 is arranged on the second surface of the back shell facing the circuit board 100.

[0059] The housing consists of a frame and a back shell. The frame is formed around the edge of the device, and the back shell covers the back of the frame. The two can be connected in an integrated manner to form a cavity for accommodating the circuit board 100. The circuit board 100 is arranged in the cavity formed by the frame and the back shell to protect the circuit board 100 from the external environment.

[0060] The first metal body 200 is arranged on the first surface of the frame body facing the circuit board 100, and the second metal body 300 is arranged on the second surface of the back shell facing the circuit board 100. The frame and the back shell can provide support for the first metal body 200 and the second metal body 300, so that the first metal body 200 and the second metal body 300 can abut against the metal spring 400. The first metal body 200 and the second metal body 300 are arranged on the frame body and the back shell.

[0061] In some embodiments, the metal spring 400 provided in Embodiment 1 of the present application can not only serve as a basic connection structure to achieve a stable electrical connection between the first metal body 200 and the second metal body 300, but can also be directly connected to the circuit board 100 for communication, and connected to the circuit board 100 as a feeding point 500. On this basis, a conventional single elastic arm antenna spring can be further added to the antenna, and the antenna spring is used to connect one of the first metal body 200 or the second metal body 300 to the ground point 600 on the circuit board 100. This configuration forms an inverted F antenna (PIFA) structure, such as Figure 8 As shown, through this structure, not only the efficient signal transmission of the antenna is achieved, but also the limited internal space is maximized. The cooperation between the first metal body 200 and the second metal body 300 and the metal spring 400, and the ground connection between the single elastic arm antenna spring and the circuit board 100, together constitute a complete signal receiving and transmitting path, supporting efficient wireless communication.

[0062] The electronic device provided in the embodiment of the present application ensures a solid and stable electrical connection channel between the antenna metal body and the circuit board 100 by adopting the metal spring 400 provided in the embodiment 1 of the present application, which significantly reduces the attenuation problem of the signal during transmission. The number of independent antenna springs required in the traditional antenna structure is reduced, which not only effectively reduces the manufacturing cost, but also reduces the space occupied by the circuit board 100 through the integrated design, which is conducive to the miniaturization design of the circuit board 100. By reducing the signal loss and impedance change caused by direct wiring on the circuit board 100, it ensures lower loss and better impedance continuity during signal transmission, thereby directly promoting the improvement of antenna performance.

[0063] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
