Description

Technical Field

[0001] This utility model relates to the field of mobile phone antenna technology, specifically a spring-loaded mobile phone antenna. Background Technology

[0002] The mobile phone antenna is a device on a mobile phone used to receive and transmit signals, and its design and layout have a significant impact on the communication quality of the mobile phone.

[0003] The primary function of a mobile phone antenna is to receive and transmit radio wave signals, enabling the phone to communicate with base stations, Wi-Fi hotspots, and other communication devices. The antenna's layout and design directly affect the phone's signal strength and communication quality.

[0004] There are various types of mobile phone antennas, including monopole antennas and dipole antennas. Early mobile phone antennas were usually external, such as whip antennas, while modern mobile phones, for aesthetic and portability reasons, mostly hide their antennas inside the body, and the antenna layout varies from phone to phone;

[0005] In most existing mobile phone antennas, the antenna is directly installed inside the phone casing and in direct contact with the motherboard. When the phone is subjected to external impact, the force may be transmitted and indirectly act on the antenna. Since the antenna itself has no protective structure, it is easy to damage the antenna and reduce its service life. Therefore, this utility model proposes a spring-loaded mobile phone antenna. Utility Model Content

[0006] The purpose of this invention is to provide a spring-loaded mobile phone antenna to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spring-loaded mobile phone antenna, comprising a mobile phone antenna body, three spring plates disposed on the back of the mobile phone antenna body, the three spring plates being respectively disposed at the front, middle and rear ends of the mobile phone antenna body, two conductive contacts being fixedly installed above the middle part of the mobile phone antenna body, and conductive contacts disposed at the tail end of the conductive contacts on the back of the mobile phone antenna body.

[0008] Preferably, a primary positioning hole is provided on one side of the mobile phone antenna body, and a secondary positioning hole is provided on the other side of the mobile phone antenna body.

[0009] Preferably, the primary positioning hole and the secondary positioning hole have the same diameter.

[0010] Preferably, the spring sheet includes a metal spring sheet with an arched structure design, and a helical spring is fixedly installed on the lower surface of the protruding part in the middle of the metal spring sheet.

[0011] Preferably, the bottom end of the helical spring is fixedly connected to the mobile phone antenna body via a washer.

[0012] Preferably, the metal spring is made of a flexible metal material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model incorporates a spring sheet. When the mobile phone is subjected to an external impact and undergoes a certain deformation, the deformation area will produce an inward indentation. The indented deformation structure will abut against the metal spring sheet. In this way, the arched structure of the metal spring sheet can better resist external forces and prevent external forces from acting directly on the mobile phone antenna.

[0015] When the impact causes the metal spring to deform, its arched protrusion will indent inward after resisting part of the external force. The indented metal spring will then push against the coil spring, thereby compressing the coil spring. The compressed coil spring has a certain elastic rebound force, which partially offsets the external force. This provides better buffering and protection for the mobile phone antenna, reduces the impact of external forces, prevents external forces from acting directly on the mobile phone antenna, and improves the service life of the mobile phone antenna.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 The present invention provides an embodiment of a spring-loaded mobile phone antenna, comprising a mobile phone antenna body 1, with three spring plates 6 disposed on the back of the mobile phone antenna body 1, the three spring plates 6 being disposed at the front, middle and rear ends of the mobile phone antenna body 1 respectively;

[0025] In order to ensure the normal electrical conduction between the mobile phone antenna body 1 and the mobile phone motherboard, two conductive contact pieces 4 are fixedly installed on the upper middle part of the mobile phone antenna body 1, and conductive contact points 5 are set at the tail end of the conductive contact pieces 4 and on the back of the mobile phone antenna body 1.

[0026] The conductive contact 5 can make electrical contact with the motherboard of a mobile phone model compatible with this utility model, thereby ensuring normal electrical transmission between this utility model and the mobile phone motherboard.

[0027] In this embodiment, in order to facilitate the positioning and connection of the mobile phone antenna body 1, a primary positioning hole 2 is provided on one side of the mobile phone antenna body 1, and a secondary positioning hole 3 is provided on the other side of the mobile phone antenna body 1.

[0028] This structural design, through the primary positioning hole 2 and the secondary positioning hole 3, can be adapted to be installed on the mobile phone motherboard, thereby engaging with the positioning protrusion of the mobile phone motherboard. This completes the positioning connection between this utility model and the externally adapted mobile phone motherboard, achieving the practical effect of positioning assembly, avoiding deviations in installation position, improving assembly accuracy and product assembly yield, and demonstrating good practical performance.

[0029] In this embodiment, in order to illustrate the structure of the spring sheet 6, the spring sheet 6 includes a metal spring sheet 601. The metal spring sheet 601 adopts an arched structure design and is made of flexible metal material. A helical spring 602 is fixedly installed on the lower surface of the protruding part in the middle of the metal spring sheet 601.

[0030] The bottom end of the helical spring 602 is fixedly connected to the mobile phone antenna body 1 through a washer;

[0031] During assembly, the mobile phone motherboard is equipped with a clearance groove that matches the position of the spring plate 6. The spring plate 6 can be inserted into the clearance groove of the mobile phone motherboard, thereby clearing the clearance of the spring plate 6 through the clearance groove adapted to the mobile phone motherboard and avoiding structural obstruction and interference.

[0032] With this structural design, when the mobile phone is subjected to an external impact and undergoes a certain deformation, its deformation area will produce an inward indentation. The indented deformation structure will resist the metal spring 601. In this way, the arched structure of the metal spring 601 can better resist external forces and prevent external forces from acting directly on the mobile phone antenna.

[0033] When the impact force causes the metal spring 601 to deform, its arched protrusion will indent inward after resisting part of the external force. The indented metal spring will push against the helical spring 602, thereby compressing the helical spring 602. The compressed helical spring 602 has a certain elastic rebound force, which partially offsets the external force through the compression and rebound of the helical spring 602. This can better buffer and protect the mobile phone antenna, reduce the impact effect of external force, avoid external force acting directly on the mobile phone antenna, and improve the service life of the mobile phone antenna.

[0034] Working principle: When in use, this utility model can be installed on the mobile phone motherboard through the set primary positioning hole 2 and secondary positioning hole 3, so as to engage with the positioning protrusion of the mobile phone motherboard. This completes the positioning connection between this utility model and the externally adapted mobile phone motherboard, which has the practical effect of positioning assembly, avoids the deviation of the installation position, improves the assembly accuracy and the product assembly yield, and has a good practical effect.

[0035] The conductive contact 5 can make electrical contact with the motherboard of the mobile phone that is compatible with this utility model, thereby ensuring normal electrical transmission between this utility model and the mobile phone motherboard.

[0036] This utility model has a spring sheet 6 structure. When the mobile phone is subjected to an external impact and undergoes a certain deformation, the deformation area will produce an inward indentation. The indented deformation structure will abut against the metal spring sheet 601. In this way, the arched structure of the metal spring sheet 601 can better resist external forces and prevent external forces from acting directly on the mobile phone antenna.

[0037] When the impact force causes the metal spring 601 to deform, its arched protrusion will indent inward after resisting part of the external force. The indented metal spring will push against the helical spring 602, thereby compressing the helical spring 602. The compressed helical spring 602 has a certain elastic rebound force, which partially offsets the external force through the compression and rebound of the helical spring 602. This can better buffer and protect the mobile phone antenna, reduce the impact effect of external force, avoid external force acting directly on the mobile phone antenna, and improve the service life of the mobile phone antenna.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
