Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted antennas, and in particular to a new energy vehicle antenna. Background Art

[0002] With the development of satellite communication technology, vehicle-mounted satellite antennas are increasingly used in vehicle mobile communications, navigation and entertainment systems. Especially in the context of the rapid development of new energy vehicles, vehicle-mounted satellite antennas, as an important component for improving intelligent driving and vehicle networking performance, have a broader application prospect. However, in the existing technology, most vehicle-mounted satellite antennas still use dish-shaped parabolic antennas, which are composed of a reflective surface, a feed source and a supporting structure. They are usually installed on the top of the vehicle to ensure the stability and coverage of signal reception. However, this type of antenna has some significant disadvantages in actual use.

[0003] First, due to the large size of the dish antenna and its installation method, which is usually exposed on the outside of the roof, this design will significantly increase air resistance during vehicle driving, which will have an adverse effect on the endurance of new energy vehicles. New energy vehicles use electricity as a driving energy source, and their range is highly sensitive to air resistance. The wind resistance effect of the dish antenna will reduce the energy efficiency of the vehicle, especially when driving at high speeds, which is contrary to the original design intention of new energy vehicles to be efficient and energy-saving. Secondly, the dish antenna is exposed to the external environment for a long time and is easily affected by weather factors. For example, rain may cause the antenna to get damp, thereby affecting the normal operation of its electronic components; the accumulation of dust and impurities will also affect the performance of the reflective surface and reduce the efficiency of signal reception. In addition, the exposed installation method increases the risk of damage to the antenna, such as mechanical damage such as collision and scratching. These problems are particularly prominent in new energy vehicles.

[0004] To this end, we propose a new energy vehicle antenna. Summary of the invention

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In order to better understand the new energy vehicle antenna provided by the embodiment of the present application, the existing vehicle antenna is briefly introduced below. The existing dish antenna has high directivity and gain due to its parabolic shape, and can receive long-distance signals or transmit high-intensity signals. However, when it is installed on the top of the vehicle, its large size is easily affected by wind resistance;

[0046] The following is a brief overview of the present application scheme. The antenna reflector 10 and the feed device 13 are folded onto the surface of the antenna base 11 through the folding mechanism 20, and cooperate with the integrated seat 21 to form a streamlined structure as a whole. When the vehicle needs to travel at high speed, the wind resistance can be reduced. When the vehicle speed drops or stops, the signal can be regained through the folding mechanism 20. At the same time, the protective cover mechanism 30 can be deployed to protect the antenna reflector 10 and other electronic components.

[0047] Example 1: Please refer to Figure 1-12 The present invention provides a technical solution: a new energy vehicle antenna, comprising:

[0048] The antenna reflector 10 is used to focus the electromagnetic waves emitted by the satellite or other sources to the feed position;

[0049] An antenna base 11, wherein the antenna base 11 is used to be connected to the top of the vehicle;

[0050] The feed device 13 is responsible for converting the received electromagnetic waves into signals and transmitting them to the receiving device, and is also used to guide the transmission signals to the reflection surface and transmit them to the satellite;

[0051] A driving mechanism 12, wherein the driving mechanism 12 is used to control the direction and angle of the antenna reflector 10 to ensure accurate alignment with the satellite. The above are all prior arts and will not be described in detail here;

[0052] The antenna further comprises: a folding mechanism 20, wherein the folding mechanism 20 comprises:

[0053] An integrated seat 21, the integrated seat 21 is rotatably connected to the antenna base 11, a joint portion 22 is provided in the middle of the top of the integrated seat 21, and rotating rods 23 are rotatably connected to both sides of the joint portion 22, and the rotating rods 23 are fixedly connected to the inner wall of the antenna reflective surface 10;

[0054] A motor 24, wherein the motor 24 is disposed in the coupling portion 22, and a gear 25 is fixedly connected to the end of the internal rotating shaft of the motor 24, and a gear 26 is meshed on the gear 25, and the gear 26 is fixedly connected to the rotating rod 23;

[0055] It should be noted that when alignment with the satellite is required, the driving mechanism 12 drives the integrated seat 21 to rotate so that the antenna reflector 10 on the top of the integrated seat 21 can be rotated to a suitable position, thereby facilitating signal reception. When the vehicle needs to travel at high speed, the gear 1 25 at the end of the internal shaft of the motor 1 24 drives the gear 2 26 to rotate, and the gear 2 26 is fixedly connected to the rotating rod 23, thereby driving the antenna reflector 10 to fold to overlap with the surface of the integrated seat 21. At the same time, the feed device 13 will be stored in the concave surface of the antenna reflector 10. Through this folding method, the windward surface of the vehicle can be reduced, thereby reducing the wind resistance of the vehicle. When the vehicle needs to receive satellite signals, the motor 1 24 drives the antenna reflector 10 to open and resume normal working state.

[0056] The antenna further comprises: a protective cover mechanism 30, wherein the protective cover mechanism 30 comprises:

[0057] A support ring assembly 31, wherein a sealing cloth 32 is provided on the support ring assembly 31;

[0058] A driving device 33, the driving device 33 is used to cooperate with the support ring assembly 31 to unfold or retract the sealing cloth 32;

[0059] It should be noted that when the antenna reflector 10 is opened, the drive device 33 will synchronously drive the support ring assembly 31 to unfold the sealing cloth 32. At this time, the sealing cloth 32 will effectively cover the antenna reflector 10 and its electronic components to prevent external factors such as rain and dust from directly affecting the function and life of the antenna reflector 10 and its electronic components. Through this protective measure, the damage caused by moisture or water intrusion can be significantly reduced, ensuring the reliability of the device under severe weather conditions. In addition, the cooperation between the sealing cloth 32 and the support ring assembly 31 not only plays an effective protective role, but also forms a buffer during driving, preventing high-altitude falling objects such as leaves and gravel from directly impacting the antenna reflector 10 and its electronic components, thereby reducing potential damage caused by impact with external objects and extending the service life of the equipment.

[0060] Further as Figure 4 and Figure 5 As shown, it is worth to explain in detail that a protrusion 211 for wrapping the antenna reflector 10 is provided at the edge of the integrated seat 21, and the edge of the antenna reflector 10 and the protrusion 211 are streamlined as a whole to reduce the wind resistance of the vehicle when it is traveling at high speed;

[0061] It should be noted that by fixing the protrusion 211 at the edge of the integrated seat 21, the protection of the edge of the antenna reflector 10 can be effectively improved. Since the edge of the antenna reflector 10 is usually thin and easily damaged by bumps or accidental collisions, the protrusion 211 provides additional protection for it to prevent the edge of the reflector from being damaged due to collisions with external objects during daily use or driving. This design effectively extends the service life of the antenna reflector 10 and reduces the cost of repair or replacement caused by damage.

[0062] It is worth noting that the entire design adopts a streamlined structure, which makes the transition between the protrusion 211 and the edge of the antenna reflector 10 smoother. The streamlined appearance not only has better aesthetics, but also significantly reduces wind resistance when driving at high speeds. Through this structural optimization, the vehicle can reduce air resistance and improve driving efficiency when driving at high speeds, while effectively reducing energy consumption and improving the overall performance of the vehicle.

[0063] According to the above embodiment, this solution also has embodiment 2:

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it is worth to explain in detail that the support ring assembly 31 includes:

[0065] A support ring 1 311, a support ring 2 312 is arranged inside the support ring 1 311, a driving ring 313 is arranged outside the antenna reflecting surface 10, a driving rod 314 is arranged on the inner wall of the antenna reflecting surface 10, one end of the driving rod 314 is rotatably connected to the rotating rod 23, and the other end is fixedly connected to the driving ring 313, the bottom layer of the sealing cloth 32 is fixedly adhered to the outer wall of the integrated seat 21, and the top layer of the sealing cloth 32 is fixedly adhered to the driving ring 313, the support ring 1 311 and the support ring 2 312 are rotatably connected to the driving ring 313, the driving device 33 includes a motor 2, the housing of the motor 2 is fixedly connected to the bottom of the antenna reflecting surface 10, the end of the internal rotating shaft of the motor 2 is fixedly connected to a gear 3, the outer wall of the driving rod 314 is fixedly connected to a gear 4, and the gear 3 is meshed with the gear 4;

[0066] It should be noted that when the antenna reflector 10 is unfolded, the gear 3 at the end of the internal shaft of the motor 2 will drive the gear 4 on the driving rod 314 to rotate synchronously, and the driving rod 314 further drives the driving ring 313 fixedly connected thereto to realize synchronous rotation with the antenna reflector 10. In this process, the sealing cloth 32 is gradually unfolded through the movement of the driving ring 313 to cover the entire antenna reflector 10. At the same time, the supporting ring 1 311 and the supporting ring 2 312 support the sealing cloth 32, so that it forms a stable and stable structure after unfolding.

[0067] The entire system has been carefully designed so that the sealing cloth 32 presents a streamlined appearance structure after being unfolded. This design can not only effectively protect the antenna reflector 10 from erosion by the external environment, such as direct contact with rain, dust or other debris, but also significantly reduce the energy consumption and performance loss caused by wind resistance during the movement of the vehicle. When the sealing cloth 32 is in the unfolded state, it forms a streamlined overall structure together with the antenna reflector 10 and related components, fully optimizing the aerodynamic performance. This design strikes a balance between protection and performance, and improves the durability of the equipment.

[0068] Further as Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the two sides of the bottom of the driving ring 313 are fixedly connected with connecting ears 315, and each of the connecting ears 315 is respectively provided with an arc groove 1 316 and an arc groove 2 317;

[0069] The inner walls of the bottoms of the support ring 1 311 and the support ring 2 312 are respectively fixedly connected with a limiting rod 318, and the arc groove 1 316 and the arc groove 2 317 cooperate with the limiting rod 318 to limit the angle between the support ring 1 311 and the support ring 2 312 relative to the driving ring 313;

[0070] It should be noted that, as the driving device 33 unfolds the driving circle 313, when the arc groove 1 316 and the arc groove 2 317 on the connecting ear 315 on the driving rod 314 abut against the limiting rod 318, the angle between the support circle 1 311 and the support circle 2 312 and the driving circle 313 will no longer increase. At this time, the support circle 1 311, the support circle 2 312, the driving circle 313 and the integrated seat 21 open the sealing cloth 32 to protect the antenna reflecting surface 10 and its internal electronic components.

[0071] Further as Figure 8 and Fig.10 As shown, it is worth to explain in detail that the included angle of the arc groove 1 316 is between 70 degrees and 85 degrees, and the included angle of the arc groove 2 317 is between 40 degrees and 50 degrees;

[0072] It should be noted that the angle of the arc groove 1 316 is set between 70 and 85 degrees. The selection of this angle range is intended to optimize the relative movement between the support ring 1 311 and the driving ring 313, so that when the antenna reflector 10 is unfolded or retracted, the cooperation between the two can be ensured to be more accurate and stable. Through this design, the arc groove 1 316 can effectively limit the angle between the support ring 1 311 and the driving ring 313, thereby avoiding excessive friction or unnecessary displacement during the movement, and improving the overall stability and operation efficiency of the system.

[0073] The angle of the arc groove 317 is set between 40 and 50 degrees. This angle range takes into account the space requirements and angle control when the antenna reflector 10 is unfolded or folded. The design of the arc groove 317 ensures a good fit between the support ring 312 and the drive ring 313, which helps to provide higher flexibility and operability during high-precision adjustment. Through this precise angle setting, mechanical jamming or malfunction caused by an angle that is too small or too large can be effectively avoided, thereby improving the reliability and service life of the equipment.

[0074] Further as Fig.11 As shown, it is worth to explain in detail that two groups of support components 40 are symmetrically arranged on both sides of the support ring 1 311 and the support ring 2 312, and the support components 40 include:

[0075] A straight rod 41, one side of which is rotatably connected to a straight rod 42, a circular groove is provided on the straight rod 41, a limit button 43 is slidably connected in the circular groove, a spring 44 is connected to the bottom of the limit button 43, one end of the spring 44 is fixedly connected to the limit button 43, and the other end is fixedly connected to the straight rod 41, and a limit groove 45 is provided on the straight rod 42;

[0076] It should be particularly noted that when the driving device 33 drives the support ring 1 311, the support ring 2 312 and the driving ring 313 to expand, the angle between the support ring 1 311 and the support ring 2 312 gradually increases. As the angles between the support ring 1 311 and the integrated seat 21, and between the support ring 2 312 and the support ring 1 311 gradually expand, the straight rod 1 41 and the straight rod 2 42 also gradually tend to a straight line state, forming a more stable support structure. When the support ring is expanded to a certain angle, the limit button 43 enters the circular groove under the action of the spring 1 44, further locking the straight rod 1 41 and the straight rod 2 42 into a straight line arrangement. At this time, the support assembly 40, the support ring 1 311 and the support ring 2 312 together form a stable triangular structure.

[0077] This design can effectively improve the stability of the entire structure and prevent instability or mechanical jamming caused by angle changes during the unfolding or folding process. Through the supporting force provided by the support assembly 40, the angle change between the support circle 1 311 and the support circle 2 312 is precisely controlled, ensuring the stability and reliability of the antenna reflector 10 when unfolded. In addition, the triangular support structure can effectively disperse and balance the force, further improving the overall rigidity and durability of the system. This optimized design not only improves performance, but also enhances the long-term stability and external force resistance of the equipment.

[0078] Further as Figure 2 As shown, it is worth specifically explaining that the straight rod 22 is fixedly connected with a connecting piece 51 on the side close to the rotating rod 23, the outer wall of the driving rod 314 is fixedly connected with a pulling plate 52, and a connecting rope 53 is fixedly connected between the connecting piece 51 and the pulling plate 52, and the connecting rope 53 is made of a flexible, non-stretchable material;

[0079] It should be noted that when the protective cover mechanism 30 needs to be stored, the driving rod 314 is driven to rotate by motor 2, and the pulling plate 52 fixedly connected to the driving rod 314 drives the connecting rope 53 to rotate outward, so that the connecting rope 53 pulls the connection between the straight rod 1 41 and the straight rod 2 42, and causes the straight rod 1 41 and the straight rod 2 42 to bend, thereby achieving the purpose of storing the protective cover mechanism 30 after the support assembly 40 is folded.

[0080] Further as Fig.12 As shown, it is worth to explain in detail that the driving circle 313 and the antenna reflecting surface 10 are connected by a flexible cloth 61, and the flexible cloth 61 is folded together;

[0081] It should be noted that when the protective cover mechanism 30 is fully unfolded, the driving circle 313 will be stationary. At this time, if the elevation angle of the antenna reflector 10 needs to be changed, the motor 1 24 drives the rotating rod 23 to rotate, so that the rotating rod 23 drives the antenna reflector 10 to rotate, and at the same time, the motor 2 at the bottom of the antenna reflector 10 drives the driving rod 314 to rotate, thereby ensuring that the driving rod 314 is stationary during the rotation of the antenna reflector 10, keeping the sealing cloth 32 in an open state at all times. At the same time, the flexible cloth 61 is folded together in a pleated form, so that the antenna reflector 10 is in a closed state during the movement relative to the driving circle 313, thereby preventing rainwater from entering the interior.

[0082] Further as Figure 1 As shown, it is worth explaining in detail that a heat dissipation fin 71 is fixedly connected to the outer side of the feed device 13, and the heat dissipation fin 71 is fixedly connected to the inner wall of the support ring 311 at one end away from the feed device 13; when the feed device 13 generates heat, the heat can reach the support ring 311 through the heat dissipation fin 71, and when the vehicle is driving, this heat will be quickly exchanged with the air, thereby achieving the purpose of cooling.

[0083] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0084] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
