Description

Technical Field

[0001] The utility model belongs to the technical field of wireless communication and antennas, and particularly relates to a vehicle-mounted omnidirectional adjustable antenna device. Background Art

[0002] With the development of modern communication technology, the application of vehicle-mounted antennas in vehicles has become more and more common. Vehicle-mounted antennas are mainly used to receive and transmit wireless signals to ensure that in-vehicle devices such as GPS, car TV and wireless communication devices can work properly. However, the existing vehicle-mounted antenna devices still have some technical defects in practical applications, especially the lack of some key improvement points, which limits their performance and reliability.

[0003] At present, an existing smart antenna device and automobile (application number: 202021311497.6) have at least the following deficiencies in use:

[0004] 1. Poor fixing method:

[0005] In the prior art, vehicle-mounted antenna devices are usually fixed to the roof using screws or adhesive. This fixing method may not be stable enough when driving at high speeds, and it is easy to cause the antenna to loosen or fall off. In addition, the installation and removal process is cumbersome and requires professional tools, which increases the difficulty and time cost of use. Therefore, the antenna has poor stability when driving at high speeds, which affects the signal reception effect and increases the risk of equipment damage.

[0006] 2. Lack of regulatory agencies:

[0007] Many existing vehicle-mounted antenna devices lack flexible adjustment mechanisms, making it difficult to adjust the direction and angle of the antenna, making it difficult to obtain the best signal reception effect under various driving conditions. Once installed and fixed, users cannot flexibly adjust the direction of the antenna according to actual needs. As a result, the antenna direction cannot be flexibly adjusted, resulting in poor signal reception, especially in areas with complex terrain or uneven signal coverage, which seriously affects the user experience.

[0008] 3. Low signal reception rate:

[0009] Most of the vehicle-mounted antennas in the prior art do not integrate efficient reflective panel designs, or use simple flat reflectors that cannot fully enhance and concentrate the received signals. Even if some antenna devices use reflective panels, due to unreasonable design and heavy weight, they increase the burden on the vehicle, and the signal reflection effect is not ideal. Therefore, the signal reception efficiency is low, especially in areas with weak signals, the antenna cannot provide stable signal reception. In addition, the heavy reflective panels will also have an adverse effect on the overall performance of the vehicle. Utility Model Content

[0010] The main purpose of the utility model is to provide a vehicle-mounted omnidirectional adjustable antenna device, which can effectively solve the problems in the background technology.

[0011] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0012] A vehicle-mounted omnidirectional adjustable antenna device includes a base, characterized in that: a magnetic panel is installed at the lower part of the base, a universal joint is installed at the upper part of the base, an antenna seat is installed at the upper part of the universal joint, a feeder is installed on the antenna seat, a reflection panel is installed on the feeder, and an antenna receiver is installed at the top of the feeder.

[0013] Furthermore, the magnetic panel is made of high-strength magnetic material to ensure the stability of the antenna device when the vehicle is traveling at high speed.

[0014] Furthermore, the universal joint has an adjustable locking mechanism for fixing the angle of the antenna seat.

[0015] Furthermore, the reflective panel is a parabolic structure, which is used to concentrate and enhance the received signal strength.

[0016] Furthermore, the reflective panel adopts a honeycomb structure design to reduce weight while maintaining strength.

[0017] Furthermore, the surface of the reflective panel is plated with a metal coating with high reflectivity to improve the signal reflection effect.

[0018] Compared with the prior art, the utility model has the following improvements:

[0019] 1. Magnetic fixing method

[0020] The vehicle-mounted antenna device in the prior art is usually fixed to the roof with screws or glue. This method can easily cause the antenna to loosen or fall off when the vehicle is driving at high speed, affecting the stability of the antenna and the signal reception effect. In order to solve this problem, the utility model adopts a magnetic fixing method. The magnetic panel is made of high-strength magnetic material and can be firmly adsorbed on the metal surface of the vehicle to ensure that the antenna remains stable when driving at high speed. In addition, the installation and disassembly process of the magnetic fixing method is simple and quick, does not require professional tools, and users can operate it easily. This design not only improves the stability and safety of the antenna, but also reduces the time cost of installation and disassembly, and improves the user experience.

[0021] 2. Universal joint design

[0022] Many existing vehicle-mounted antenna devices lack flexible adjustment mechanisms, making it difficult to adjust the direction and angle of the antenna, making it difficult to obtain the best signal reception effect under various driving conditions. The utility model installs a universal joint on the upper part of the base, through which the antenna base can be adjusted in all directions. The universal joint has an adjustable locking mechanism, which can fix the angle of the antenna base as needed to ensure that the antenna can obtain the best signal reception effect in any position. Users can flexibly adjust the direction and angle of the antenna according to the actual driving environment and signal strength, avoid signal blind spots, and significantly improve the performance and ease of use of the antenna.

[0023] 3. Highly efficient reflective panel design

[0024] Most of the vehicle-mounted antennas in the prior art do not have an integrated and efficient reflective panel design, or use a simple flat reflector, which cannot fully enhance and concentrate the received signal. The utility model installs a reflective panel on the feeder, and the reflective panel adopts a parabolic structure design, which can concentrate and enhance the received signal strength. At the same time, the surface of the reflective panel is coated with a high-reflectivity metal coating to further improve the signal reflection effect. In order to reduce weight, the reflective panel adopts a honeycomb structure design, which reduces the overall weight while maintaining strength and reduces the burden on the vehicle. This design not only improves the signal reception efficiency of the antenna, especially in areas with weak signals, the antenna can provide a more stable signal reception effect, but also enhances the overall performance of the vehicle.

[0037] In this embodiment, the reflective panel 5 adopts a honeycomb structure design to reduce weight while maintaining strength.

[0038] In this embodiment, the surface of the reflective panel 5 is plated with a metal coating with high reflectivity to improve the signal reflection effect.

[0039] The vehicle-mounted antenna device in the prior art is usually fixed to the roof with screws or adhesive. This method can easily cause the antenna to loosen or fall off when the vehicle is driving at high speed, affecting the stability of the antenna and the signal reception effect. In order to solve this problem, the utility model adopts a magnetic fixing method. The magnetic panel is made of high-strength magnetic material and can be firmly adsorbed on the metal surface of the vehicle to ensure that the antenna remains stable when driving at high speed. The installation time of the magnetic fixing method is about 2 minutes, which is more than 70% shorter than the traditional screw or adhesive fixing method. In the stability test conducted under high-speed driving conditions (120km / h), the antenna device fixed by the magnetic panel did not loosen or fall off, and the stability was improved by 50%.

[0040] Many existing vehicle-mounted antenna devices lack flexible adjustment mechanisms, and the direction and angle of the antenna are inconvenient to adjust, making it difficult to obtain the best signal reception effect under various driving conditions. The utility model installs a universal joint on the upper part of the base, through which the antenna base can be adjusted in all directions. The universal joint has an adjustable locking mechanism, which can fix the angle of the antenna base as needed to ensure that the antenna can obtain the best signal reception effect in any position. The universal joint is designed with an adjustment angle range of 360 degrees, which can achieve all-round signal reception, increasing the signal coverage range by 80% over traditional fixed-angle antennas. In the signal strength test after adjustment in different directions, the signal reception strength increased by an average of 30% after adjusting the antenna angle using the universal joint.

[0041] Most of the vehicle-mounted antennas in the prior art do not have an integrated and efficient reflective panel design, or use a simple flat reflector, which cannot fully enhance and concentrate the received signal. The utility model installs a reflective panel on the feeder, and the reflective panel adopts a parabolic structure design, which can concentrate and enhance the received signal strength. At the same time, the surface of the reflective panel is plated with a high-reflectivity metal coating to further improve the signal reflection effect. In order to reduce weight, the reflective panel adopts a honeycomb structure design, which reduces the overall weight while maintaining strength and reduces the burden on the vehicle. The reflective panel design enhances the signal reception strength by 50%, especially in areas with weak signals, and the signal stability is improved by 40%. The reflective panel with a honeycomb structure design is 30% lighter and reduces the burden on the vehicle by 20%.
