Description

Technical Field

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

[0002] Today's cars are becoming more and more intelligent, especially new energy vehicles, which need to maintain a stable network status after starting. Therefore, in order to enhance signal reception, current new energy vehicles are often equipped with on-board antennas.

[0003] There are two common types of antennas for ordinary family cars. One is a shark fin-shaped antenna, attached to the roof of the car. This type of antenna has the advantage of being low, less likely to collide with obstacles, and has low wind resistance. The other is a tree branch-shaped antenna. This type of antenna extends higher and has a wider reception area, thus providing better signal reception than the shark fin-shaped antenna. However, this tree branch-shaped antenna is more likely to contact obstacles such as branches and door frames, and has greater wind resistance.

[0004] Especially in off-road conditions, the signal is generally poor in the wild, and an enhanced antenna is needed. The situation in the wild is complicated, and sometimes it is necessary to pass through woods, bushes and other areas. Therefore, shark fin-shaped antennas and tree branch-shaped antennas are not very suitable. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a networked car antenna to solve the technical problem that the two commonly used car antennas in the prior art are difficult to achieve both enhanced signal reception capability and collision avoidance and reduced wind resistance.

[0006] A networked car antenna includes a base and an external antenna portion movably mounted within the base. The base is shark fin-shaped and fixedly mounted on the top of the car.

[0009] Furthermore, a winding motor is provided in the base, and the winding roller is fixedly connected to the output shaft of the winding motor. The lower end of the main antenna passes through the bottom of the lowest main antenna and is wound on the winding roller after adjusting the direction through a steering pulley.

[0010] Furthermore, a movable groove running through the top and bottom is provided on the top of the base, and the main antenna passes through the movable groove and is slidably connected thereto.

DETAILED DESCRIPTION

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0027] The first aspect of the present invention is as follows Figure 1 and Figure 2 As shown, the present invention primarily consists of a base 101 and an external antenna portion that is retractably connected to the base 101. The base 101 is shark fin-shaped and fixedly mounted on the roof of the vehicle. Both the base 101 and the external antenna portion are also connected to the vehicle's central control system. Extending and retracting the main antenna 102 causes the present invention to switch between two antenna states. When the main antenna 102 is fully retracted into the base 101, the antenna state resembles a conventional shark fin antenna. When the main antenna 102 is extended, especially when fully extended, the base 101, main antenna 102, and branch antenna 105 work together to receive and transmit signals, significantly improving signal transmission and reception capabilities.

[0028] Specifically, such as Figure 3 As shown, the external antenna section comprises a retractable multi-stage main antenna 102 and four equiangularly arranged branch antennas 105. Each stage of the main antenna 102 is telescopically and slidably connected to the main antenna 102 of the next stage. The lowest main antenna 102 is located within the base 101, and its bottom is rotatably connected to the base 101 via an antenna shaft 112. The branch antennas 105 are rotatably connected to a connecting tube 122, which is fixedly connected to the upper end of a connecting rod 103, which is fixedly connected to the top of the highest main antenna 102.

[0029] The mechanism for retracting the main antenna 102 and the branch antenna 105 consists of a single-strand cable 106, a multi-strand cable 107, a winding roller 109, and a winding motor 110. One end of the single-strand cable 106 is fixedly connected to the bottom of the branch antenna 105, while the other end of the single-strand cable 106 extends into the interior of the uppermost main antenna 102 and is fixedly connected to the top of the multi-strand cable 107. The multi-strand cable 107 is located inside the main antenna 102. The lower end of the main antenna 102 passes through the bottom of the lowermost main antenna 102 and is oriented by a deflection pulley 111 before being wound around the winding roller 109. The deflection pulley 111 is rotatably connected to the base 101. The winding roller 109 is fixedly connected to the output shaft of the winding motor 110, which is fixedly mounted within the base 101.

[0030] When the main antenna 102 and the branch antenna 105 need to be retracted into the base 101, it is only necessary to start the winding motor 110. The winding motor 110 rotates forward to drive the winding roller 109 to rewind the multi-strand rope 107. The multi-strand rope 107 will first pull the single-strand rope 106 into the uppermost main antenna 102. During this process, the single-strand rope 106 will pull the branch antenna 105 to shrink, so that the branch antenna 105 is attached to the outer surface of the connecting rod 103. Finally, the branch antenna 105 is pulled into the uppermost main antenna 102 together with the connecting rod 103. The winding roller 109 then rewinds the multi-strand rope 107, and the uppermost main antenna 102 will be pulled into the second-highest main antenna 102. And so on, finally all the main antennas 102 and the branch antennas 105 enter the lowermost main antenna 102. Since the lowest main antenna 102 is located in the base 101 and its bottom is rotatably connected to the base 101 via the antenna shaft 112 , the main antenna 102 and the branch antenna 105 are completely retracted into the base 101 .

[0031] Preferably, a cover plate 104 is fixedly connected to the top of the connecting tube 122 , and after the main antenna 102 and the branch antenna 105 are completely retracted into the base 101 , the cover plate 104 can completely cover the movable groove 113 on the top of the base 101 .

[0032] The mechanism for extending the main antenna 102 and the branch antenna 105 is that an extension spring 108 is provided in the main antenna 102 of each level. The extension spring 108 is arranged outside the multi-strand rope 107, and the lower end of the extension spring 108 is connected to the bottom of the main antenna 102 where it is located, and the upper end of the extension spring 108 is connected to the bottom end of the main antenna 102 of the upper level.

[0033] In addition, if Figure 4As shown, the support antenna 105 is rotatably connected to the connecting tube 122 via a connecting shaft 125. The top of the connecting tube 122 is fixedly connected to the cover 104, and an opening spring 124 is provided in the connecting tube 122. The upper end of the opening spring 124 is connected to the bottom of the cover 104, and the lower end of the opening spring 124 is connected to the pressure plate 123. The pressure plate 123 is slidably connected in the connecting tube 122, and the lower end of the pressure plate 123 abuts against the hemispherical top of the support antenna 105, so as to force the support antenna 105 to open with the connecting shaft 125 as the center.

[0034] When the main antenna 102 and the branch antenna 105 need to be extended, the reel motor 110 is activated, which rotates in the opposite direction, driving the winding roller 109 to release the multi-strand cable 107. At this point, the extension spring 108 automatically extends each stage of the main antenna 102. Furthermore, the connecting rod 103 and the connecting tube 122 are also automatically extended by the extension spring 108 in the uppermost main antenna 102. The branch antenna 105 is then released, and the pressure plate 123 descends under the action of the expansion spring 124. Since the lower end of the pressure plate 123 abuts the hemispherical top of the branch antenna 105, the pressure plate 123 presses the branch antenna 105 to expand around the connecting shaft 125.

[0035] On the other hand, Figure 3 and Figure 5 As shown, a movable slot 113 is provided on the top of the base 101, extending vertically. The main antenna 102 passes through the movable slot 113 and is slidably connected thereto. The front-to-back length of the movable slot 113 is greater than the diameter of the lowest main antenna 102, and the width of the movable slot 113 is the same as the diameter of the lowest main antenna 102. The movable slot 113 provides the main antenna 102 with sufficient room to move. When encountering strong wind resistance or encountering obstacles, the main antenna 102 can rotate and tilt for smooth passage.

[0036] Preferably, a damping mechanism is also provided, comprising a fixed cylinder 118, a telescopic rod 119, and a damping spring 120. The fixed cylinder 118 is fixedly connected to the base 101. The inner end of the telescopic rod 119 is slidably connected to the fixed cylinder 118, and its outer end abuts the outer wall of the lowest main antenna 102. The damping spring 120 is disposed within the fixed cylinder 118, with its ends respectively connected to the fixed cylinder 118 and the telescopic rod 119. The outer end of the telescopic rod 119 is also rotatably connected to a roller 121, and the telescopic rod 119 is connected to the outer wall of the lowest main antenna 102 via the roller 121.

[0037] When encountering large wind resistance or hitting an obstacle, the main antenna 102 rotates and tilts to squeeze the roller 121. The roller 121 is compressed and shrinks together with the telescopic rod 119 into the fixed tube 118. The damping spring 120 plays a damping role, which can keep the main antenna in the best vertical state as much as possible after passing the obstacle.

[0038] On the other hand, Figure 3 As shown, an air inlet 114 is provided at the front end of the base 101, and a drainage hole 115 is provided at the rear end of the base 101. A blocking member 116 is also provided at the air inlet 114 in the base 101. The blocking member 116 is slidably connected in the base 101 and fixedly connected to the output shaft of the telescopic motor 117. The telescopic motor 117 is fixedly connected in the base 101.

[0039] Because movable groove 113 may cause water to enter base 101, when rapid drainage is required, telescopic motor 117 is activated to retract blocking member 116, exposing air inlet 114. Airflow from high-speed vehicle travel enters through air inlet 114 and exits through drain hole 115, rapidly removing moisture, dust, and other debris. If rapid drainage is not required, telescopic motor 117 is used to drive blocking member 116 to block air inlet 114, allowing drain hole 115 to drain naturally. Blocking air inlet 114 prevents moisture or other debris from entering when the vehicle is parked. Specific embodiments

[0040] First, the base 101 is fixedly installed on the top of the car, and the base 101, the main antenna 102 and the branch antenna 105 are also connected to the central control system of the car.

[0041] When used in a city with good signal, the main antenna 102 and the branch antenna 105 can be retracted into the base 101 to reduce wind resistance. Or when encountering special road conditions, such as when passing through the woods, the main antenna 102 and the branch antenna 105 need to be retracted into the base 101. First, start the winding motor 110, and the winding motor 110 rotates forward to drive the winding roller 109 to wind up the multi-strand rope 107. The multi-strand rope 107 will first pull the single-strand rope 106 into the uppermost main antenna 102. During this process, the single-strand rope 106 will pull the branch antenna 105 to shrink, so that the branch antenna 105 is attached to the outer surface of the connecting rod 103. Finally, the branch antenna 105 is pulled into the uppermost main antenna 102 together with the connecting rod 103. The winding roller 109 then winds up the multi-strand rope 107, and the uppermost main antenna 102 will be pulled into the second-upper main antenna 102. And so on, finally all the main antennas 102 and the branch antennas 105 enter the lowermost main antenna 102. Since the lowest main antenna 102 is located in the base 101 and its bottom is rotatably connected to the base 101 via the antenna shaft 112 , the main antenna 102 and the branch antenna 105 are completely retracted into the base 101 .

[0042] When driving outdoors and the signal is poor, the main antenna 102 and the branch antenna 105 can be extended, and the winding motor 110 is activated. The winding motor 110 rotates in the opposite direction, driving the winding roller 109 to release the multi-strand cable 107. At this time, the extension spring 108 automatically extends each stage of the main antenna 102. In addition, the connecting rod 103 and the connecting tube 122 are also automatically extended by the extension spring 108 in the uppermost main antenna 102. Then, the branch antenna 105 is also released. Under the action of the expansion spring 124, the pressure plate 123 is lowered. Because the lower end of the pressure plate 123 abuts the hemispherical top of the branch antenna 105, the pressure plate 123 presses the branch antenna 105 to expand around the connecting shaft 125.

[0043] Based on the above, the present invention is able to switch between two antenna states by providing a shark fin-shaped base 101 and a main antenna 102 telescopically connected to the base, thereby being able to take into account both the need to enhance signal reception and the need to avoid collisions and reduce wind resistance. The main antenna 102 is extended by a spring and can be retracted by clicking on the reel cable, making it easy to operate. In addition, a damping mechanism is provided to enable the main antenna 102 to maintain an optimal vertical state as much as possible after extension, and to allow the main antenna 102 to rotate and tilt for smooth passage when encountering greater wind resistance or encountering obstacles. An air inlet 114 and a drainage hole 115 are also provided, which can utilize the airflow generated by the high-speed driving of the car to quickly drain the moisture in the base 101.

Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
