[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0053] In the description of this embodiment, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this embodiment. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this embodiment, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.

[0055] Vehicle-mounted antennas in related technologies have the following drawbacks: ① Vehicle-mounted antennas lack illumination, making it difficult for installers to quickly identify the antenna's location in dark environments where visibility is limited. Furthermore, they cannot produce dynamic lighting effects to attract fashion-conscious young consumers and meet the personalized modification needs of passenger vehicles. ② The antenna mast and base are typically connected by threads, with internal and external threads pre-embedded in the base and mast via injection molding. This results in high material and injection molding costs, reducing the product's market competitiveness. Additionally, due to the threaded connection, the threads may loosen under long-term vibration, leading to signal loss. ③ Vehicle-mounted antennas are generally passive due to insufficient waterproofing, resulting in low signal strength and a risk of malfunction in harsh environments. To address these technical deficiencies, this utility model provides a vehicle-mounted antenna.

[0056] The embodiments of this utility model are described below with reference to Figures 1 to 8.

[0057] A vehicle-mounted antenna according to an embodiment of the present invention includes a base 100, a light-emitting unit, a transparent antenna rod sleeve 200, and a light guide 300. The base 100 is used for mounting on a vehicle body, and a mounting cavity 110 is provided inside the base 100. The light-emitting unit is disposed in the mounting cavity 110, and the transparent antenna rod sleeve 200 is disposed at the upper end of the base 100 along the axial direction. The interior of the transparent antenna rod sleeve 200 communicates with the mounting cavity 110. The light guide 300 is disposed inside the transparent antenna rod sleeve 200, and the light guide 300 receives the light emitted by the light-emitting unit and diffuses the received light from the surface of the light guide 300.

[0058] The vehicle-mounted antenna of this embodiment is made of transparent material through the transparent antenna rod sleeve 200, and a light guide part 300 is provided inside the transparent antenna rod sleeve 200. When it is necessary to disassemble or install the vehicle-mounted antenna of this embodiment from the vehicle body in a dark environment, the light-emitting unit can be turned on to transmit light into the light guide part 300. The light guide part 300 can emit light throughout, and the light diffused from the surface of the light guide part 300 can diffuse to the outside through the transparent antenna rod sleeve 200, so that the vehicle-mounted antenna of this embodiment forms a fully luminous effect, thereby facilitating the location indication for installation personnel and reducing the difficulty of disassembling or installing the vehicle-mounted antenna of this embodiment from the vehicle body in a dark environment.

[0059] It should be noted that the dark environment mentioned in the article refers to a special environment in which the installation workers cannot clearly observe the location of the antenna even when the vehicle's lights are turned on.

[0060] It should be noted that the vehicle-mounted antenna in this embodiment can be applied to modified passenger vehicles, as well as to special operation vehicles such as agricultural and hoisting vehicles.

[0061] It is understood that the axis mentioned in the text refers to the axis of the transparent antenna mast 200. The arrangement directions of the center line of the light guide 300, the center line of the LED bead 420 and the center line of the transparent antenna mast 200 are all parallel to the axis. For ease of description, the axis in Figure 1 is used as the axis for description, but it should not be understood as a specific limitation on the axis of the transparent antenna mast 200.

[0062] As shown in Figures 2 and 3, in some embodiments, the light-emitting unit includes a PCBA board 410 and LED beads 420. The PCBA board 410 is disposed within the mounting cavity 110; the LED beads 420 are disposed at one end of the PCBA board 410 facing the light guide portion 300; the axial projection of the LED beads 420 falls within the range of the light guide portion 300. Because the axial projection of the LED beads 420 falls within the range of the light guide portion 300, the light emitted by the LED beads 420 through circuit control is basically received by the light guide portion 300, reducing light loss and improving the overall light-emitting effect of the vehicle antenna in this embodiment, thus providing better position indication for installation personnel.

[0063] It should be noted that PCBA mentioned in the text is short for Printed Circuit Board Assembly. PCBA board 410 refers to the mounting of electronic components on a printed circuit board (PCB) and connecting the components through processes such as soldering to form a complete circuit system.

[0064] As shown in Figures 3, 4, 6, and 7, specifically, the outer peripheral surface of the PCBA board 410 is provided with at least one limiting groove 411, preferably six limiting grooves 411. The six limiting grooves 411 are arranged at intervals along the circumference of the PCBA board 410, and the limiting grooves 411 penetrate the PCBA board 410 axially. The inner wall of the mounting cavity 110 is provided with limiting portions 140 corresponding to the limiting grooves 411. During the process of installing the PCBA board 410 into the mounting cavity 110, assembly can be achieved by aligning the limiting grooves 411 with the limiting portions 140 and interlocking them, which is simple to operate.

[0065] To improve the accuracy and ease of installing the PCBA board 410 into the mounting cavity 110, as shown in Figures 4, 6 and 7, more specifically, the PCBA board 410 is provided with a positioning through hole 412, and a positioning post 150 is provided in the mounting cavity 110 at the position corresponding to the positioning through hole 412.

[0066] Specifically, one end of the light guide 300 extends into the mounting cavity 110 and is located directly above the LED bead 420; shortening the axial distance between the light-inlet end of the light guide 300 and the light-emitting end of the LED bead 420 helps to reduce the loss of light emitted by the LED bead 420 during the process of being received by the light guide 300, and helps to improve the overall light emission effect of the vehicle antenna in this embodiment.

[0067] It is understandable that the light-emitting end of the LED bead 420 refers to the end of the LED bead 420 facing the light guide section 300.

[0068] More specifically, the axial spacing between the light-inlet end of the light guide 300 and the light-emitting end of the LED bead 420 is set to 0.5 mm to 1 mm.

[0069] Specifically, the center line of the light guide 300 overlaps with the center line of the LED bead 420, which helps to evenly distribute the light emitted by the LED bead 420 on the surface of the light guide 300, thereby improving the overall light emission effect of the vehicle antenna in this embodiment.

[0070] As shown in Figures 2 and 3, specifically, the light guide 300 is configured as an optical fiber light guide strip. The optical fiber light guide strip can evenly distribute the light emitted by the LED beads 420 along the length of the optical fiber light guide strip, providing a soft and uniform lighting effect, and achieving the goal of providing position indication lighting for installation workers without producing glare.

[0071] When the vehicle antenna of this embodiment is applied to modified passenger vehicles, the LED light beads 420 are controlled by the circuit to emit light and work in conjunction with the optical fiber light guide strip to form a dynamic lighting effect, attracting young audiences who pursue fashion and meeting their personalized modification needs.

[0072] As shown in Figures 2 and 3, in some embodiments, the vehicle-mounted antenna further includes a spring antenna 500, which is disposed within the transparent antenna sleeve 200 and fitted over the light guide portion 300. One end of the spring antenna 500 extends out of the mounting cavity 110 and connects to the PCBA board 410. By adjusting the helical pitch of the spring antenna 500, single or multi-functional combinations such as AM / FM, DAB, LTE, WIFI, and BLE can be achieved, adapting to various communication frequency bands. Furthermore, by fitting the spring antenna 500 onto the light guide portion 300, the structure becomes more compact and smaller, making it particularly suitable for applications with high space requirements.

[0073] As shown in Figures 2, 3, 6, and 7, in some embodiments, the side wall of the base 100 has a cable outlet hole 120 for the signal output line 600 to pass through. A waterproof sealant 610 is provided between the wall of the cable outlet hole 120 and the outer surface of the signal output line 600. One end of the signal output line 600 extending into the mounting cavity 110 is connected to the PCBA board 410. By filling the space between the wall of the cable outlet hole 120 and the outer surface of the signal output line 600 with waterproof sealant 610 through potting, water (such as rainwater) is effectively prevented from entering the mounting cavity 110 through the gap between the cable outlet hole 120 and the signal output line 600, improving the overall waterproof performance of the vehicle-mounted antenna in this embodiment. This allows for the addition of active circuitry within the mounting cavity 110 to enhance the signal, enabling the vehicle-mounted antenna of this embodiment to operate stably even in environments with poor signal strength.

[0074] Specifically, the signal output line 600 is also used to provide power to the PCBA board 410.

[0075] As shown in Figures 2 and 3, in some embodiments, one end of the transparent antenna sleeve 200 is embedded in the mounting cavity 110 for connection. A first sealing ring 710 is provided between the outer wall of the portion of the transparent antenna sleeve 200 embedded in the mounting cavity 110 and the inner wall of the mounting cavity 110. The first sealing ring 710 can effectively prevent water (such as rainwater) from entering the mounting cavity 110 through the gap at the connection between the transparent antenna sleeve 200 and the base 100, thereby improving the overall waterproof performance of the vehicle antenna of this embodiment. This allows for the addition of active circuitry within the mounting cavity 110 to achieve signal enhancement, enabling the vehicle antenna of this embodiment to operate stably even in environments with poor signal strength.

[0076] Specifically, two first sealing rings 710 are provided, and the two first sealing rings 710 are spaced apart along the axial direction to form two waterproof lines, which is more conducive to improving the overall waterproof performance of the vehicle antenna in this embodiment.

[0077] As shown in Figures 3 and 5, specifically, the outer wall of the transparent antenna mast 200 is recessed with a first annular groove 212, and the first sealing ring 710 is embedded in the first annular groove 212; so that during the assembly of the transparent antenna mast 200 and the base 100, the first sealing ring 710 is not easy to fall out of the first annular groove 212, thus achieving a better waterproof sealing effect.

[0078] As shown in Figures 1 and 2, in some embodiments, an antenna cap 720 is provided at the end of the transparent antenna mast 200 facing away from the base 100, and a second sealing ring 730 is provided at the connection between the antenna cap 720 and the transparent antenna mast 200. The antenna cap 720 serves both an aesthetic and protective function; at the same time, the second sealing ring 730 forms a waterproof line at the connection between the antenna cap 720 and the transparent antenna mast 200, effectively preventing water (such as rainwater) from entering the interior of the transparent antenna mast 200 through the gap at the connection between the antenna cap 720 and the transparent antenna mast 200 and ultimately entering the mounting cavity 110, thereby improving the overall waterproof performance of the vehicle-mounted antenna in this embodiment. This allows for the addition of active circuitry within the mounting cavity 110 to achieve signal enhancement.

[0079] It is understandable that the transparent antenna mast 200 has an inner cavity formed through the center along the axial direction.

[0080] As shown in Figures 2 and 5, specifically, the end of the transparent antenna mast 200 facing the antenna cap 720 is configured as a mounting portion 220. The outer diameter of the mounting portion 220 is smaller than the outer diameter of the transparent antenna mast 200, and the mounting portion 220 is interference-fitted into the antenna cap 720. The smaller-diameter mounting portion 220 is connected to the antenna cap 720, and the step formed by the mounting portion 220 and the transparent antenna mast 200 serves as a reference for precise positioning, ensuring accurate assembly of the antenna cap 720. This also allows the outer diameter of the transparent antenna mast 200 to be the same as the outer diameter of the antenna cap 720, improving the appearance of the vehicle-mounted antenna in this embodiment. More specifically, a second sealing ring 730 is disposed between the antenna cap 720 and the mounting portion 220.

[0081] As shown in Figures 2, 3, and 8, in some embodiments, the base 100 has a recessed mounting groove at the end opposite to the transparent antenna mast 200, and a magnet 810 is embedded in the mounting groove. A waterproof sticker 820 is provided on the end face of the base 100 opposite to the transparent antenna mast 200, covering the mounting groove. The magnet 810 is located in the mounting groove at the bottom of the base 100, allowing the vehicle antenna of this embodiment to be magnetically attached to the vehicle body sheet metal, facilitating installation and making it particularly suitable for aftermarket applications. Simultaneously, by attaching the waterproof sticker 820 between the magnet 810 and the vehicle body sheet metal, and by covering the mounting groove with the waterproof sticker 820, water (specifically rainwater) is effectively prevented from entering the mounting cavity 110 from the bottom of the base 100, improving the overall waterproof performance of the vehicle antenna of this embodiment.

[0082] Understandably, the magnet 810 can pass through the waterproof sticker 820 and generate a magnetic attraction with the vehicle sheet metal to fix the vehicle antenna of this embodiment to the vehicle body.

[0083] It should be noted that the mounting groove and the mounting cavity 110 are connected, that is, the mounting groove and the mounting cavity 110 are set as one piece, and the magnet 810 is interference-fitted in the mounting groove to fix the magnet 810 and waterproof it.

[0084] In some embodiments, the transparent antenna sleeve 200 is connected to the base 100 via a snap-fit ​​structure. Compared to connecting the transparent antenna sleeve 200 and the base 100 via threads, there are drawbacks such as the high cost of materials and injection molding due to the internal and external threads being pre-embedded in the base 100 and the transparent antenna sleeve 200 respectively through injection molding, and the possibility of the threads loosening under long-term vibration, leading to antenna signal loss. In this embodiment, the transparent antenna sleeve 200 is fixedly connected to the base 100 via a snap-fit ​​structure, reducing the risk of loosening between the transparent antenna sleeve 200 and the base 100 under long-term vibration, and also preventing malicious theft.

[0085] The specific structure of the snap-fit ​​structure in this embodiment will be described in detail below.

[0086] As shown in Figures 3, 4, 5 and 7, in some embodiments, the snap-fit ​​structure includes an elastic buckle 910 and a slot 920. The elastic buckle 910 is disposed on the inner wall of the mounting cavity 110; the slot 920 is disposed on the outer wall of the transparent antenna mast sleeve 200 at the position corresponding to the elastic buckle 910, and the slot 920 is adapted to snap-fit ​​with the elastic buckle 910. When assembling the transparent antenna mast sleeve 200 with the base 100, the elastic buckle 910 and the slot 920 are first aligned axially. Then, the end of the transparent antenna mast sleeve 200 facing the base 100 (i.e., the end with the slot 920) is inserted into the mounting cavity 110. During insertion, the elastic buckle 910 deforms under the pressure applied by the transparent antenna mast sleeve 200. After insertion until the elastic buckle 910 is aligned with the slot 920, the pressure applied to the elastic buckle 910 disappears, and the elastic buckle 910 elastically returns to its original position and embeds itself into the slot 920 to achieve a fastening. The entire assembly process is convenient. It also reduces the number of tools required during assembly, which is beneficial for automated mass production, improves production efficiency, reduces labor costs, and enhances market competitiveness.

[0087] To improve the connection and tightness between the transparent antenna mast sleeve 200 and the base 100, as shown in Figure 5, specifically, three slots 920 are provided, and the three slots 920 are equally spaced along the circumference of the transparent antenna mast sleeve 200. Correspondingly, three elastic buckles 910 are also provided.

[0088] In specific applications, the number of slots 920 and elastic buckles 910 can be reasonably increased or decreased according to actual needs. For example, in other embodiments, slots 920 and elastic buckles 910 can be provided in one, two, or three or other quantities.

[0089] As shown in Figures 1 to 4, specifically, the end of the base 100 facing the transparent antenna sleeve 200 is configured as a tapered portion 130, and the outer diameter of the tapered portion 130 gradually decreases axially towards the transparent antenna sleeve 200; the tapered portion 130 has a straight hole 131 extending axially, and the straight hole 131 communicates with the mounting cavity 110; the elastic buckle 910 is disposed on the inner wall of the straight hole 131. The tapered portion 130 provides a transitional connection between the transparent antenna sleeve 200 and the base 100, thereby increasing the mounting connection area between the base 100 and the vehicle body to ensure the stability of the vehicle-mounted antenna installed on the vehicle body, while reducing the overall volume of the vehicle-mounted antenna in this embodiment.

[0090] As shown in Figures 2, 3, and 5, specifically, the end of the transparent antenna mast 200 facing the base 100 is configured as a connecting portion 210. The outer diameter of the connecting portion 210 is smaller than the outer diameter of the transparent antenna mast 200, and the slot 920 is provided on the outer side wall of the connecting portion 210. The stepped surface formed by the connecting portion 210 and the transparent antenna mast 200 serves a positioning function, so that when the connecting portion 210 is inserted to the position where the bottom end of the transparent antenna mast 200 abuts against the top end of the conical portion 130, the elastic buckle 910 elastically resets and embeds into the slot 920 to achieve a fastening; and it can make the outer diameter of the transparent antenna mast 200 the same as the outer diameter of the top surface of the conical portion 130, improving the appearance of the vehicle antenna in this embodiment.

[0091] It should be noted that the bottom end of the transparent antenna mast 200 mentioned in the text refers to the end of the transparent antenna mast 200 facing the base 100; the top end of the conical part 130 refers to the end of the conical part 130 facing the transparent antenna mast 200.

[0092] As shown in Figure 5, specifically, the first annular groove 212 is provided on the outer wall of the connecting part 210.

[0093] As shown in Figures 3 and 4, specifically, the elastic buckle 910 is configured with a first guide slope 911 along the radial direction of the transparent antenna mast sleeve 200 towards the side wall of the connecting portion 210. The first guide slope 911 extends axially from the top end of the elastic buckle 910 to the bottom end of the elastic buckle 910, and the first guide slope 911 is gradually inclined towards the center line of the transparent antenna mast sleeve 200. This allows the installation operator to apply only a small amount of downward pressure so that the connecting portion 210 can cross the elastic buckle 910 along the first guide slope 911, achieving elastic reset and embedding of the elastic buckle 910 into the slot 920 to complete the fastening. It can be understood that the top end of the elastic buckle 910 refers to the end facing the transparent antenna mast sleeve 200 axially, and the bottom end of the elastic buckle 910 refers to the end facing away from the transparent antenna mast sleeve 200 axially.

[0094] As shown in Figures 3 and 5, specifically, the outer wall of the end of the connecting portion 210 facing the base 100 is configured as a second guide slope 211. The second guide slope 211 extends axially from the bottom end to the top end of the connecting portion 210, and is inclined away from the center line of the transparent antenna mast sleeve 200. This allows the installation operator to apply only a small amount of downward pressure so that the elastic buckle 910 can cross the connecting portion 210 along the second guide slope 211, achieving elastic reset and embedding into the slot 920 to complete the fastening.
