Description

Technical Field

[0001] This utility model relates to dash cams, specifically a dash cam with a conveniently retractable antenna. Background Technology

[0002] A dashcam is a device that records images, sounds, location, speed, and other information while a vehicle is in motion. It can provide evidence in traffic accidents and is an important auxiliary device for vehicle travel. With the widespread application of 4G communication technology in the dashcam field, users have placed higher demands on the antenna performance, structural compactness, and aesthetic appearance of the devices.

[0003] Currently, dashcam antennas on the market mainly fall into two design categories, both with significant drawbacks: The first is the built-in antenna design. This design is susceptible to electromagnetic interference from within the device, leading to communication lag, shortened transmission distance, and severely impacting the user experience. Furthermore, built-in antennas occupy considerable space within the device casing, hindering the proper layout of the heat dissipation structure, resulting in excessive heat generation and reduced overall reliability. The second is the coaxial external antenna design. While it can improve signal reception quality to some extent, it suffers from complex wiring and poor overall aesthetics, failing to meet market demands for convenience and visual appeal.

[0004] Therefore, there is an urgent need for an antenna structure that combines signal stability, high space utilization, and convenient installation to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of current dash cams, such as signal instability, low space utilization, and inconvenient installation, and to provide a dash cam with a conveniently stored antenna that offers high signal stability, high space utilization, and easy installation.

[0006] The purpose of this utility model is achieved through the following technical solution: a conveniently retractable antenna-type dash cam, comprising a dash cam body and a retractable antenna assembly, wherein the retractable antenna assembly consists of an antenna body, a storage mechanism and a connecting component; the storage mechanism is used to drive the antenna body to unfold or retract, and one end of the connecting component is connected to the antenna body, and the other end is connected to the main board inside the dash cam body.

[0007] Furthermore, the storage mechanism includes an antenna front shell, an antenna rear shell, a bracket front shell, and a bracket rear shell; after the antenna front shell and the antenna rear shell are closed, an antenna receiving cavity is formed inside. A hollow shaft structure that can rotate relative to the antenna rear shell is also provided on the antenna rear shell. The antenna body is located inside the antenna rear shell and is connected to the hollow shaft structure.

[0008] Furthermore, a damping rubber ring is provided inside the storage mechanism on the outside of the hollow shaft structure, and a fastening ring is also provided inside the storage mechanism. The fastening ring is located at the end of the hollow shaft structure and is fixedly connected to the rear shell of the bracket by screws.

[0009] The connecting component is a shielded coaxial cable, one end of which is connected to the antenna body and the other end is connected to the motherboard inside the recorder body.

[0010] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) This utility model adopts an external retractable antenna body in conjunction with a shielded coaxial cable, which effectively avoids the problem of traditional built-in antennas being susceptible to electromagnetic interference inside the device, reduces communication lag, and extends signal transmission distance; at the same time, compared with ordinary external antennas, this structure does not require complicated wiring, improves the ease of installation, and can stably meet the needs of 4G communication, WIFI connection and other scenarios.

[0011] (2) The antenna body of this utility model is externally stored through a storage mechanism, which does not require occupying a large amount of space inside the recorder body shell, and provides sufficient layout space for the heat dissipation structure. This effectively solves the problem of excessive heat generation caused by insufficient space in traditional built-in antennas, reduces the risk of overall machine failure, and extends the service life of the equipment.

[0012] (3) In the storage mechanism of this utility model, the hollow shaft structure of the antenna rear shell, combined with the damping rubber ring, can realize the antenna body rotation at any angle during the rotation process, which makes it convenient for users to adjust the antenna position according to the signal environment; the combination of fastening ring and screw can limit the maximum rotation angle of the antenna and ensure the structural stability in the storage state. The overall volume is small after storage and does not affect the appearance coordination of the equipment.

[0013] (4) The entire retractable antenna assembly of this utility model has a simple structure and is easy to manufacture. At the same time, the external design facilitates the inspection and replacement of the antenna. It can be maintained without disassembling the main body of the recorder, reducing the difficulty and cost of later maintenance. It is more economical than complex external antenna solutions.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0020] Example

[0021] like Figure 1 , 2 As shown in the figure, the retractable antenna-type dashcam described in this embodiment mainly includes two parts: the dashcam body 1 and the retractable antenna assembly. The retractable antenna assembly consists of three parts: the antenna body 4, the storage mechanism 2, and the connecting component 12.

[0022] Inside the main body 1 of the recorder is a motherboard 13, which serves as the "control center" of the dashcam. It integrates various circuits and chips required for the operation of the device, and can coordinate and control the basic functions of the recorder such as recording, storage, and display. At the same time, it is responsible for processing the signals transmitted by the antenna body 4. That is, after receiving external signals such as 4G / WIFI from the antenna body 4, it analyzes and converts them through relevant modules on the motherboard 13 to ensure that the signal is stable for network connection, data transmission (such as video upload), etc. Conversely, it can also transmit signals that the device needs to send out (such as network requests) to the antenna body 4 to achieve two-way signal interaction.

[0023] The storage mechanism 2 is used to drive the antenna body 4 to unfold or retract. One end of the connecting component 12 is connected to the antenna body 4, and the other end is connected to the motherboard 13 inside the recorder body 1.

[0024] The specific structure of the storage mechanism 2 is as follows: Figure 3 As shown, it includes an antenna front shell 3, an antenna rear shell 5, a bracket front shell 10, and a bracket rear shell 7. When the antenna front shell 3 and the antenna rear shell 5 are closed together, an antenna receiving cavity is formed inside, and the antenna body 4 is disposed inside this antenna receiving cavity.

[0025] A hollow shaft structure 11, which can rotate relative to the antenna rear shell 5, is also provided on the antenna rear shell 5. The interior of the hollow shaft structure 11 is hollow, allowing the connecting component 12 to pass through. That is, the hollow shaft structure 11 is the transmission component for the unfolding and retraction of the antenna body 4. It cooperates with the through hole on the bracket rear shell 7 to provide rotational support for the antenna rear shell 5 and the antenna body 4 inside, so that the antenna body 4 can rotate around the axis of the hollow shaft structure 11, thereby realizing the switching between the two states of "extending to enhance the signal" and "retracting to save space", meeting the user's needs for antenna use and storage in different scenarios.

[0026] To better achieve the unfolded or retracted state, as one of the preferred methods, this embodiment can also provide a damping rubber ring 6 on the outside of the hollow shaft structure 11. This allows the hollow shaft structure 11 and the damping rubber ring 6 to work together to enable the antenna body 4 to stop rotating at any angle during the rotation process, making it convenient for users to adjust the antenna position according to the signal environment.

[0027] Meanwhile, to limit the maximum rotation angle of the antenna body 4 and ensure structural stability in the retracted state, a fastening ring 8 can also be provided inside the retracting mechanism in this embodiment. During connection, the fastening ring 8 is located at the end of the hollow shaft structure 11 and is fixedly connected to the rear shell 7 of the bracket by screws 9.

[0028] The connecting component 12 is the core component for achieving stable signal transmission between the antenna body 4 and the main board 13. It preferably uses a shielded coaxial cable, and its connection structure is as follows: Figure 4 As shown.

[0029] During connection, one end of the connecting component 12 is directly connected to the antenna body 4, and the other end extends through the hollow part of the hollow shaft structure 11 into the interior of the recorder body 1, and precisely docks with the RF antenna connector set on the motherboard 13, thereby forming a complete signal transmission link of "antenna body-coaxial cable-motherboard", ensuring that the 4G / WIFI signal received by the antenna can be effectively transmitted to the motherboard 13, and at the same time, the signals that the motherboard 13 needs to send out (such as network request, data upload command) can also be transmitted to the antenna body 4 through this link.

[0030] In this embodiment, the connecting component 12 is implemented using a coaxial cable. This not only isolates external electromagnetic interference, preventing interference signals from entering the transmission link and affecting antenna signal quality, but also solves the problems of communication lag and shortened transmission distance caused by the lack of shielding protection and susceptibility to electromagnetic interference in traditional built-in antennas, ensuring the stability and integrity of 4G / WIFI signals during transmission. Furthermore, because the coaxial cable is a flexible structure, it can flexibly deform with the unfolding or retracting of the antenna body 4. This prevents the cable from breaking or being damaged due to antenna rotation, and also does not hinder the retracting mechanism from achieving functions such as "stopping at any angle" and "limiting the maximum rotation angle," ensuring that the antenna assembly is compact in the retracted state and stable in the unfolded state.

[0031] As described above, this utility model can be well realized.
