Description

Technical Field

[0001] The utility model belongs to the technical field of automobile intelligent antennas, in particular to a highly wind-resistant automobile intelligent antenna. Background Art

[0002] A car antenna is a device that intercepts high-frequency radio waves emitted by a transmitter and transmits them to the receiver of a car radio, car phone or radio navigation equipment to demodulate the carrier.

[0003] At present, the installation method of automobile antennas generally adopts the combination of bolts and nuts for fixing. During installation, the bolts reserved on the automobile antenna need to be passed through the through holes on the automobile first, and then the nuts are put on the bolts as anti-dropping parts to achieve fixing. Due to the small internal space of the automobile, it is inconvenient for operators to operate. In addition, only the combination of bolts and nuts is used for fixing. After long-term use, the sealing of the contact part between the antenna and the automobile is difficult to ensure, and the overall wind resistance effect is also poor.

[0004] In view of this, a highly wind-resistant automotive smart antenna is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a highly wind-resistant automotive intelligent antenna in order to solve the above-mentioned problems.

[0006] The technical solution adopted by the utility model is as follows: a highly wind-resistant automobile intelligent antenna, comprising an antenna shell with an antenna, the bottom wall of the antenna shell is recessed inward to form a accommodating cavity, the bottom edge of the antenna shell is provided with a rubber strip, the bottom of the antenna shell is provided with a connector connected to a car receiving device, the bottom of the antenna shell is protruding to form a sealing ring for covering the connector, and a negative pressure area is formed between the antenna shell, the rubber strip and the sealing ring, which is used to adsorb the antenna shell as a whole on the car.

[0007] In a preferred embodiment, a waterproof sealing ring is embedded in the bottom circumferential surface of the sealing ring and is at the same height as the rubber strip.

[0008] In a preferred embodiment, one side of the connector is electrically connected to a transmission line connected to a receiving device of the vehicle, and the bottom of the connector has a locking assembly that is locked to the bottom of a through hole reserved in the vehicle.

[0009] In a preferred embodiment, the locking assembly includes a fastening bolt and a mounting ring, the mounting ring is movably sleeved on the lower side of the connector, and the diameter of the mounting ring is the same as the diameter of the reserved through hole of the automobile.

[0010] In a preferred embodiment, a plurality of elastic metal sheets are circumferentially disposed on the upper end surface of the mounting ring, and the plurality of elastic metal sheets are all inclined upward and are integrally combined to form a "petal" shape.

[0011] In a preferred embodiment, a hole is opened in the center of the mounting ring to allow the fastening bolt to pass through, and the fastening bolt passes through the mounting ring and is threaded into a threaded hole reserved at the bottom of the connector.

[0012] In a preferred embodiment, the antenna housing is in the shape of a "shark fin" as a whole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present invention, a sealing ring is designed inside the antenna housing. When the antenna housing is installed on a car, a rubber strip can be used to discharge part of the gas inside the accommodating cavity. The negative pressure area formed at this time can adsorb the antenna housing on the car, thereby ensuring the subsequent fixing effect of the antenna. In addition, the sealing parts arranged inside and outside can also ensure the overall waterproof effect;

[0015] 2. In the utility model, after the antenna shell is initially positioned, the fastening bolts that are inserted into the car are rotated inward. When the fastening bolts are rotated, the elastic metal sheets are driven to move upward until a plurality of elastic metal sheets are bent and pressed against the inner wall of the car, thereby completing the overall fixing operation. Compared with the traditional fixing method, it is simpler, and the dual fixing of negative pressure adsorption and metal sheets can improve the overall fixing effect of the antenna, thereby ensuring the overall wind resistance effect.

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] Reference Figure 1-4 A highly wind-resistant automotive intelligent antenna comprises an antenna shell 1 having an antenna, characterized in that: the bottom wall of the antenna shell 1 is recessed inward to form a receiving cavity, a rubber strip 3 is provided at the bottom edge of the antenna shell 1, a connector 8 connected to a car receiving device is provided at the bottom of the antenna shell 1, a sealing ring 2 for covering the connector 8 is formed on the bottom of the antenna shell 1, a negative pressure area 4 is formed between the antenna shell 1, the rubber strip 3 and the sealing ring, and is used to adsorb the antenna shell 1 as a whole on the car, a sealing ring 2 is designed inside the antenna shell 1, and when the antenna shell 1 is installed on the car, part of the gas inside the receiving cavity can be discharged by using the rubber strip 3, and the negative pressure area formed at this time can adsorb the antenna shell 1 on the car, thereby ensuring the subsequent fixing effect of the antenna.

[0023] Furthermore, a waterproof sealing ring is embedded in the bottom circumference of the sealing ring 2 at the same height as the rubber strip 3. Through the cooperation of the waterproof sealing ring and the rubber strip 3, a double sealing effect can be achieved, thereby ensuring the overall waterproof effect.

[0024] Furthermore, one side of the connector 8 is electrically connected to a transmission line 6 connected to a car receiving device (not shown in the figure, and the details are not repeated here for the prior art). The bottom of the connector 8 has a locking assembly that is locked to the bottom of a reserved through hole in the car. The data received by the antenna can be transmitted to the car receiving device through the transmission line 6.

[0025] Furthermore, the locking assembly includes a fastening bolt 5 and a mounting ring 7. The mounting ring 7 is movably sleeved on the lower side of the connector 8. The diameter of the mounting ring 7 is the same as the diameter of the through hole reserved in the car. A plurality of elastic metal sheets 701 are circumferentially arranged on the upper end surface of the mounting ring 7. The plurality of elastic metal sheets 701 are all inclined upward and are combined as a whole to form a "petal" shape. A hole is provided in the center of the mounting ring 7 to allow the fastening bolt 5 to pass through. The fastening bolt 5 passes through the mounting ring 7 and is threaded into the threaded hole reserved at the bottom of the connector 8. When installing the antenna, the locking assembly is extended into the car, and then the fastening bolt 5 is rotated from the car. When the fastening bolt 5 is rotated, the mounting ring 7 and the elastic metal sheet 701 are driven to move upward until the plurality of elastic metal sheets 701 are bent and pressed tightly against the inner wall of the car, thereby completing the overall fixing operation. Compared with the traditional fixing method, it is simpler, and there are a plurality of elastic metal sheets 701, so that there can be a plurality of fixing points and the overall fixing effect can be guaranteed.

[0026] An elastic gasket is arranged between the mounting ring 7 and the fastening bolt 5 .

[0027] Furthermore, the antenna housing 1 is in the shape of a “shark fin” as a whole, and the above shape can reduce the wind resistance of the car, thereby improving the additional wind resistance effect.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
