Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted antenna technology, and more specifically to a vehicle-mounted antenna mounting structure. Background Technology

[0002] With the development of communication technology, antennas are commonly installed on automobiles to provide communication signals such as FM, AM, and GPS. Vehicle antennas are generally installed on the outside of the vehicle's roof to receive and radiate wireless signals. Given their size and weight, vehicle antennas need to be stably fixed to the roof to prevent them from falling off. Currently, common antenna mounting devices can be divided into detachable and non-detachable types. Detachable mounting devices require the mounting components to be removed during vehicle assembly. After the antenna body positioning structure is passed through the opening in the roof, the mounting components are reassembled. This type of antenna mounting device requires disassembly and reinstallation, which is cumbersome and inefficient. Summary of the Invention

[0003] The technical problem solved by this invention is the low assembly efficiency caused by the need to disassemble and reinstall fixed components during existing antenna assembly. This invention provides a vehicle-mounted antenna installation structure that can solve this problem.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a vehicle-mounted antenna mounting structure, including an antenna body, a fixing mechanism and a pre-fixing mechanism, wherein both the fixing mechanism and the pre-fixing mechanism are mounted on the antenna body; the fixing mechanism is screwed onto the antenna body, and the pre-fixing mechanism is snapped onto the fixing mechanism; the fixing mechanism fixes the antenna body to the vehicle body, and the pre-fixing mechanism pre-fixes the antenna body to the vehicle body before the fixing mechanism is fixedly installed on the vehicle body.

[0005] Furthermore, the pre-fixing mechanism is provided with at least two first hooks on its periphery, each of the first hooks facing outwards.

[0006] Furthermore, the fixing mechanism is provided with a locking platform, and the pre-fixing mechanism is provided with a second locking hook, which can lock the locking platform.

[0007] Furthermore, the fixing mechanism includes a screw and a fixing claw. The fixing claw is screwed onto the antenna body by the screw, and the fixing claw undergoes outward deformation when squeezed by the screw.

[0008] Furthermore, the fixing claw is provided with a recessed deformation position, and the fixing claw bends and deforms at the recessed deformation position when it is squeezed by the screw.

[0009] Furthermore, the fixing mechanism also includes an abutment portion, which is disposed on the outside of the fixing claw. When the fixing claw is deformed by the screw, the abutment portion opens outward and can abut against the side wall of the vehicle body.

[0010] Furthermore, the end of the abutment portion has a spike-like structure.

[0011] Furthermore, the abutment portion is provided with reinforcing ribs.

[0012] Furthermore, the antenna body is also provided with a plurality of positioning posts, which are located on the outside of the antenna body and can position the antenna body to be installed in the mounting holes of the vehicle body.

[0013] Furthermore, a sealing ring is also provided on the antenna body, and the sealing ring is located on the side of the antenna body close to the vehicle body.

[0014] The main advantages of this invention are as follows: The vehicle-mounted antenna mounting structure incorporates a pre-fixing mechanism. Before the fixing mechanism is fully installed on the vehicle body, the antenna body is pre-fixed to the vehicle body via this mechanism. During installation, the pre-fixing device's hooks engage with the roof, limiting the antenna body's Z-axis offset and facilitating more accurate assembly and positioning. Furthermore, the fixing mechanism can pass entirely through the roof opening before installing the deformed antenna body, eliminating the need for disassembly during assembly and further improving the installation efficiency of the vehicle-mounted antenna.

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] See Figures 1-8 A vehicle-mounted antenna mounting structure is disclosed for mounting an antenna on a vehicle body, such as the roof. The structure includes an antenna body 1, a fixing mechanism 2, and a pre-fixing mechanism 3. The antenna body 1 is the main structure of the vehicle-mounted antenna, including a housing, a PCB board mounted inside the housing, and multiple antenna radiating arms mounted on the PCB board. Both the fixing mechanism 2 and the pre-fixing mechanism 3 are mounted on the antenna body 1. The fixing mechanism 2 fixes the antenna body 1 to the vehicle body, and the pre-fixing mechanism 3 pre-fixes the antenna body 1 to the vehicle body before the fixing mechanism 2 is fixedly installed. During installation, the pre-fixing device 3's hook 31 abuts against the roof, limiting the Z-axis offset of the antenna body and facilitating more accurate assembly and positioning of the vehicle-mounted antenna. Simultaneously, the fixing mechanism can completely pass through the roof opening before installing the deformed fixed antenna body, eliminating the need for disassembly during assembly and further improving the installation efficiency of the vehicle-mounted antenna.

[0027] See Figure 1 , 2 5 and 6, the pre-fixing mechanism 3 can adopt the following specific structure: at least two first hooks 31 are provided on the periphery, each first hook 31 is set outward, so that when the vehicle antenna is installed with the vehicle body, the first hooks 31 can extend from the mounting holes 41 on the roof 4 and lock around the side walls of the mounting holes 41 to fix the antenna body to the vehicle body. Two or more first hooks 31 can be provided. In this embodiment, four are provided, which are respectively locked onto the left and right side walls of the mounting holes 41.

[0028] See Figure 2 , 56. The pre-fixing mechanism 3 and the fixing mechanism 2 can be connected by the following specific structure: the fixing mechanism 2 is provided with a locking platform 24, and the pre-fixing mechanism 3 is provided with a second locking hook 32. The second locking hook 32 can lock the locking platform 24, thereby connecting the pre-fixing mechanism 3 and the fixing mechanism 2 together. The fixing mechanism 2 is screwed together with the antenna body 1, thus fixing both the pre-fixing mechanism 3 and the fixing mechanism 2 to the antenna body 1, forming an integral structure. It is preferable to provide two or more sets of the second locking hook 32 and the locking platform 24, located on various sides of the pre-fixing mechanism 3 and the fixing mechanism 2, to better connect the two together.

[0029] See Figures 1-4 In accordance with points 6-8, the fixing mechanism 2 can adopt the following specific structure: it includes a screw 21 and a fixing claw 22. The fixing claw 22 is screwed onto the screw hole 13 of the antenna body 1 by the screw 21. The fixing claw 22 is a flexible structure. When the fixing claw 22 is squeezed by the screw 21, it undergoes outward deformation. During installation, the fixing claw 22 passes from the outside of the vehicle body to the inside of the vehicle body, thereby fixing the antenna body 1 to the vehicle body 4 through the outward deformation structure. The fixing claw 22 can be a metal structure that can be deformed under pressure, preferably a structure that can be elastically deformed. The elastic deformation can return to its original shape when the external force is removed, which facilitates the repeated disassembly and installation of the vehicle-mounted antenna structure on the vehicle body. It is preferable to have two or more fixing claws 22. In this embodiment, three are provided.

[0030] See Figure 4 , 7 As a further preferred embodiment, the fixing claw 22 is preferably provided with a recessed deformation position 221. The recessed deformation position 221 is relatively thinner than other nearby positions and is easier to bend under force. Therefore, when the fixing claw 22 is squeezed by the screw 21, it bends and deforms at the recessed deformation position 221, fixing the antenna body 1 to the vehicle body 4. It is preferable to provide one recessed deformation position 221 on each opposite side of each fixing claw 22, so that the fixing claw 22 can easily produce a "zigzag" deformation, which better fixes the antenna body 1 to the vehicle body 4.

[0031] See Figure 1 , 2 In addition to the above, the fixing mechanism 2 is preferably further provided with an abutment portion 23. The abutment portion 23 is located on the outer side of the fixing claw 22, away from the end of the fixing claw 22 that is subjected to force deformation. When the fixing claw 22 is deformed by the screw 21, the abutment portion 23 opens outward and can abut against the side wall of the vehicle body 4, further fixing the antenna body 1 more stably to the vehicle body. It is preferable to provide a reinforcing rib 231 on the abutment portion 23 to enhance its strength and better fix the vehicle-mounted antenna. The fixing mechanism 2 can be a stamped metal structure.

[0032] See Figure 1 , 2 4, 7 and 8, the end of the contact part 23 is preferably set as a spike-like structure, so that the spike-like structure can pierce the paint protective layer on the roof wall and directly contact the metal part of the roof to form an electrical connection, grounding the vehicle antenna and making it more convenient to ground the vehicle antenna.

[0033] See Figures 1-3 In addition to point 6, it is preferable to provide multiple positioning posts 11 on the antenna body 1. The positioning posts 11 are located on the outer side of the antenna body 1, and their positions match the size of the mounting holes 41 on the vehicle body 4. Each positioning post 11 can be engaged with the inner wall of the mounting hole 41, thereby positioning and installing the antenna body 1 within the mounting hole 41 of the vehicle body 4, further facilitating the installation of the vehicle-mounted antenna structure on the vehicle body. In this embodiment, three positioning posts 11 are provided, which are precisely engaged at the three corners of the mounting hole 41, positioning the antenna body 1 within the mounting hole 41.

[0034] See Figure 2 and Figure 3 As a further preferred embodiment, the antenna body 1 is also provided with a sealing ring 12. The sealing ring 12 is located on the side of the antenna body 1 closest to the vehicle body. When the vehicle-mounted antenna structure is installed on the vehicle body, the sealing ring 12 can be secured between the antenna body and the vehicle body, forming a sealed structure to prevent moisture and other contaminants from entering the vehicle. The sealing ring 12 can be made of silicone, and a mounting groove 14 is provided on the antenna body 1 to position and install the sealing ring 12 within the mounting groove 14.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
