DETAILED DESCRIPTION

[0029] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0030] Combination Figures 1 to 10 As shown, a vehicle-mounted antenna assembly disclosed in the present invention includes a vehicle-mounted antenna and a fixing device, and the fixing device fixes the vehicle-mounted antenna to the vehicle sheet metal. In this embodiment, the vehicle-mounted antenna and the fixing device are described in detail by taking the vehicle-mounted antenna being fixed to the roof sheet metal a by the fixing device as an example. Of course, in other embodiments, the fixing position of the vehicle-mounted antenna can be set according to actual needs.

[0031] The vehicle-mounted antenna includes a base 10, an antenna body (not shown) mounted on the base 10, and a shell d covering the outside of the antenna body. The fixing device includes two fixing members 20, an elastic member 30, and a fastener 40. The base 10 includes a base 10a and a mounting seat 50 connected to the base 10a, and the mounting seat 50 is used to mount the two fixing members 20, the elastic member 30, and the fastener 40. The mounting seat 50 has an extended end face 50a and a circumferential outer side face 50b, wherein the mounting seat 50 is provided with a receiving cavity formed by being recessed from the extended end face 50a toward the base 10a. The mounting seat 50 includes a limiting column 52 arranged in the receiving cavity, the limiting column 52 extends along the axial direction of the mounting seat 50, and a receiving groove 51 is formed between the inner wall surface of the receiving cavity and the outer wall surface of the limiting column 52, and the elastic member 30 is sleeved on the limiting column 52 and located in the receiving groove 51. The receiving cavity has two side walls arranged opposite to each other, and each side wall is provided with two guide holes 53 opening upwards, and the guide holes 53 are for inserting the fixing member 20, and the two fixing members 20 are respectively installed on the two side walls. The outer wall surface of each side wall is provided with two openings 54, and the two openings 54 are respectively connected with the two guide holes 53, and the fixing member 20 can pass through the openings 54 after being inserted into the guide holes 53. The limiting column 52 is provided with a matching portion 521, and the fastener 40 is locked and fixed with the matching portion 521 to fix the fixing member 20 between the mounting seat 50 and the fastener 40. In this embodiment, the fixing device is provided with two fixing members 20 in total. Of course, in other embodiments, the number of fixing members 20 can be set according to actual needs. In this embodiment, the mounting seat 50 and the base 10a adopt an integrally formed structure. Of course, in other embodiments, the mounting seat 50 can also be fixed to the base 10a in an integral manner by a movable connection, such as bolt fixing. In this embodiment, the fastener 40 is a fastening bolt, the matching portion 521 is a threaded hole, and the fastener 40 is locked and fixed to the matching portion 521 by rotation.

[0032] The fixing member 20 is a stamping part, which includes a main body 21 and two abutting portions 22 extending from one side of the main body 21. The two abutting portions 22 extend in the same direction and are arranged in parallel. The two fixing members 20 are respectively installed on the two side walls of the receiving cavity, and the two abutting portions 22 of each fixing member 20 are correspondingly inserted into the two guide holes 53 of the side wall. The main body 21 includes a base 23 and a hook portion 24 extending from the base 23. The hook portion 24 is rotatably connected to the elastic member 30. The elastic member 30 has a supporting effect on the fixing member 20 to prevent the fixing member 20 from automatically moving toward the base 10a without external force. The elastic member 30 is preferably a spring. An obtuse angle is formed between the plane where the base 23 is located and the plane where the two abutting portions 22 are located. The fastener 40 presses the base 23 toward the base 10a during the process of locking and fixing with the matching portion 521, and the hook portion 24 rotates around the elastic member 30, and the abutting portion 22 passes through the opening 54. The base body 23 includes two crimping portions 231 extending in the same direction and arranged in parallel, and the hook portion 24 is formed by bending at the middle position of the two crimping portions 231 .

[0033] When the two fixing members 20, the elastic member 30 and the fastener 40 are preassembled on the mounting seat 50, the elastic member 30 is received in the receiving groove 51 of the mounting seat 50, the two fixing members 20 are respectively installed on the two side walls of the receiving cavity, and the two abutting portions 22 of each fixing member 20 are respectively received in the two guide holes 53 of the side walls of the receiving cavity, the hook portion 24 of the fixing member 20 is rotatably connected to the elastic member 30, the fastener 40 is preinstalled on the matching portion 521, and the fastener 40 abuts against the base 23 of the fixing member 20 to prevent the fixing member 20 and the elastic member 30 from falling off the mounting seat 50. At this time, the abutting portion 22 of the fixing member 20 does not pass through the opening portion 54 of the side wall of the receiving cavity, so that the abutting portion 22 of the fixing member 20 is located in the contour area formed by the mounting seat 50, which is convenient for the fixing member 20, the elastic member 30, the fastener 40 and the mounting seat 50 preassembled in one to pass through the through hole b of the roof sheet metal a.

[0034] In the process of the fastener 40 being locked and fixed to the matching portion 521 in the direction of the base 10a, the fastener 40 presses the base 23 of the fixing member 20 in the direction of the base 10a. Since there is an obtuse angle between the plane where the base 23 is located and the plane where the two abutting portions 22 are located, the hook portion 24 is rotatably connected to the elastic member 30. Therefore, in the process of the base 23 being pressed and moving in the direction of the base 10a, the hook portion 24 rotates around the elastic member 30. The base 23 and the hook portion 24 jointly press the elastic member 30 in the direction of the base 10a. The abutting portion 22 passes through the opening 54 under the guidance of the guide hole 53. The fastener 40 is moved out and toward both sides of the mounting seat 50. As the fastener 40 is continuously locked on the matching portion 521 toward the base 10a, the end of the abutting portion 22 is continuously expanded toward both sides of the mounting seat 50. The distance between the end of the abutting portion 22 and the roof sheet metal a is gradually reduced during the expansion of the abutting portion 22. Finally, the fastener 40 is locked and fixed on the matching portion 521, the fixing member 20 is fixed between the mounting seat 50 and the fastener 40, the abutting portion 22 of the fixing member 20 is crimped onto the roof sheet metal a, and the roof sheet metal a is fixed between the base 10a of the base 10 and the abutting portion 22 of the fixing member 20.

[0035] Combination Figure 2 and Figure 3 As shown, the mounting seat 50 is provided with two threading grooves 55, and the threading grooves 55 are arranged through the mounting seat 50, and the base 10a is provided with a first through groove 11 corresponding to the threading groove 55. During implementation, the wire harness c of the vehicle-mounted antenna passes through the first through groove 11 of the base 10a and enters the threading groove 55, and further passes out of the threading groove 55 to be electrically connected to the corresponding equipment in the vehicle. In this embodiment, the mounting seat 50 is provided with two relatively arranged threading grooves 55, so that different wire harnesses can pass through the mounting seat 50 and be electrically connected to the corresponding equipment in the vehicle. Of course, in other embodiments, the number and arrangement position of the threading grooves 55 can be set according to actual needs.

[0036] Combination Figure 1 and Figure 6 As shown, the vehicle-mounted antenna assembly also includes a buckle 60 for pre-fixing the roof sheet metal a and the base 10 of the vehicle-mounted antenna. The buckle 60 includes a buckle body 61 and two oppositely arranged hook parts 62 extending from the buckle body 61, and the hook parts 62 are arranged perpendicular to the buckle body 61. The base 10a is provided with a second through slot 12 for the hook part 62 to pass through, and the mounting seat 50 is provided with a receiving groove 56 that intersects with the second through slot 12. After the buckle 60 is assembled in place, the hook part 62 passes through the second through slot 12 of the base 10a and is received in the receiving grooves 56 on both sides of the mounting seat 50. During implementation, after the fixing member 20, the elastic member 30, the fastener 40 and the mounting seat 50 pre-assembled in one body pass through the through hole b of the roof sheet metal a, the hook part 62 is clamped to the roof sheet metal a to achieve pre-fixation of the roof sheet metal a and the base 10.

[0037] Combination Figure 2 and Figure 3 As shown, the base 10a is provided with two oppositely arranged abutting protrusions 13. After the roof sheet metal a and the base 10 of the vehicle-mounted antenna are pre-fixed, the abutting protrusions 13 abut against the roof sheet metal a. After the abutting portion 22 of the fixing member 20 is expanded outward to the position, the abutting portion 22 of the fixing member 20 is crimped to the roof sheet metal a. At this time, each abutting protrusion 13 and the two abutting portions 22 of each fixing member 20 are correspondingly arranged on both sides of the roof sheet metal a. The arrangement of the abutting protrusions 13 makes the roof sheet metal a more firmly fixed between the base 10a and the abutting portion 22.

[0038] The vehicle-mounted antenna assembly also includes a waterproof member 70, which is a circular ring-shaped structure. The waterproof member 70 is sleeved on the mounting seat 50. When implemented, after the mounting seat 50 sleeved with the waterproof member 70 passes through the through hole b of the roof sheet metal a, the waterproof member 70 is located between the base 10a and the roof sheet metal a. After the fixing member 20 is fixed between the mounting seat 50 and the fastener 40, the abutment portion 22 of the fixing member 20 is pressed against the roof sheet metal a. At this time, the two sides of the waterproof member 70 are respectively tightly attached to the base 10a and the roof sheet metal a. This design can prevent liquid from entering the vehicle through the through hole b of the roof sheet metal a. In this embodiment, the waterproof member 70 is a waterproof foam. Of course, in other embodiments, the waterproof member 70 can also be a waterproof rubber, etc., which can be selected according to actual needs.

[0039] When the vehicle-mounted antenna is installed and fixed to the roof sheet metal a by the fixing device described in the present invention, the antenna body and the shell d are first installed on the base 10, the wire harness c is passed through the first through slot 11 of the base 10a, and passed through the threading slot 55 of the mounting seat 50, and the two fixing members 20, the elastic member 30, the fastener 40 and the mounting seat 50 are further pre-assembled into one body, that is, the elastic member 30 is sleeved on the limiting column 52 and is located in the receiving groove 51, and the abutting portions 22 of the two fixing members 20 are inserted into the corresponding guide holes 53 of the two side walls of the receiving cavity, and the hook portion 24 of each fixing member 20 is rotatably connected to the elastic member 30, so that the fixing member 20 will not move toward the base 10a under the action of gravity, and the fastener 40 is further pre-installed in the matching portion 521. At this time, the fastener 40 is not in a locked state, and the fixing member 20 is not in a fixed state. In this state, the abutting portions 22 of the two fixing members 20 are always located in the guide hole 53. At the same time, the waterproof member 70 is sleeved on the mounting seat 50 .

[0040] The two fixing members 20, the elastic member 30, the fastener 40 and the mounting seat 50 preassembled into one are passed through the through hole b of the roof sheet metal a. After passing through the through hole b, the roof sheet metal a and the base 10 of the vehicle-mounted antenna are pre-fixed by the buckle 60. The fixing member 20 is further fixed by the fastener 40, so that the fixing member 20 is fixed between the mounting seat 50 and the fastener 40, and the abutting portion 22 of the fixing member 20 is crimped to the roof sheet metal a, so that the roof sheet metal a is fixed between the base 10a of the base 10 and the abutting portion 22 of the fixing member 20, thereby realizing the installation and fixation between the vehicle-mounted antenna and the roof sheet metal a.

[0041] When removing the vehicle-mounted antenna, the fastener 40 is loosened. Due to the reaction force of the elastic member 30, the fixing member 20 moves in a direction away from the base 10a under the joint action of the elastic member 30 and the guide hole 53. As the fastener 40 is continuously loosened, the abutting portion 22 of the fixing member 20 eventually enters the guide hole 53 from the opening 54. At this time, the vehicle-mounted antenna can be separated from the roof sheet metal a, thereby realizing the removal of the vehicle-mounted antenna.

[0042] The fixing device for the vehicle-mounted antenna described in the present invention adopts a fixing member 20 and an elastic member 30 to replace the mounting spring sheet in the prior art. The fixing member 20 hardly deforms when fixing the vehicle-mounted antenna. After the vehicle-mounted antenna is removed, the fixing member 20 can be reused, which saves costs and reduces waste. During assembly, the fixing member 20, the elastic member 30, the fastener 40 and the mounting seat 50 are first pre-assembled into one body, and then passed through the through hole b of the roof sheet metal a together. The fixing member 20 further fixes the roof sheet metal a between the abutment portion 22 and the base 10a under the action of the fastener 40, thereby reducing assembly complexity and improving assembly efficiency.

[0043] The technical contents and technical features of the present invention have been disclosed as above. However, those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should not be limited to the contents disclosed in the embodiments, but should include various substitutions and modifications that do not depart from the present invention and are covered by the claims of this patent application.
