Description

Technical Field

[0001] The utility model relates to the technical field of antennas, and in particular to a novel antenna structure with a waterproof function. Background Art

[0002] With the development of automobile intelligence, the number of vehicle-mounted antennas inside cars has increased, and the installation locations have become more diverse. Some car antennas need to be placed in wet areas. In these locations, vehicle-mounted antennas are easily affected by various external environmental factors, such as rain, dust, vibration, etc., resulting in unstable antenna signal quality, increased interference or signal loss.

[0003] Currently, waterproof antennas on the market usually use a whole waterproof pad to surround the edge of the box, and the waterproof pad is tightened by screws to obtain waterproof capability. Although this method can solve the waterproof problem, the waterproof capability is limited and the consistency is poor due to the low rigidity of the plastic parts. On this basis, the internal space of the antenna needs to be occupied for waterproofing, and the available space of the antenna is greatly compressed. In addition, the method of surrounding the waterproof pad requires a lot of time in the antenna assembly process. The waterproof pad needs to be aligned with the shell on each side and inserted into the groove, and the screws need to be tightened at the end, making the assembly process cumbersome. Utility Model Content

[0004] The purpose of the utility model is to provide a new antenna structure with a waterproof function. By arranging a waterproof ring inside the wire outlet, a large amount of space occupied by waterproofing in the prior art is reduced, the utilization rate of the internal space of the antenna is improved, and at the same time high waterproof performance is achieved, ensuring the stability and reliability of the antenna.

[0005] The utility model is implemented as follows: a novel antenna structure with waterproof function, comprising:

[0006] A housing having a cavity therein;

[0007] A wire outlet portion, provided on the housing, the wire outlet portion having a wire outlet hole communicating with the cavity, the wire outlet hole being used for allowing the wire harness to pass through;

[0008] A waterproof ring is arranged in the wire outlet hole, and the waterproof ring has a first through hole coaxial with the wire outlet hole; and

[0009] The plug cap is sleeved on the outer periphery of the outlet portion, and the plug cap includes a baffle, the baffle abuts against the surface of the outlet hole away from the cavity, and the baffle is provided with a second through hole opposite to the outlet hole.

[0010] In the above technical solution, by setting the outlet portion on the housing and setting the outlet hole for the wire harness to pass through, the utility model only needs to waterproof the outlet portion when in use, thereby improving the utilization rate of the internal space of the housing. At the same time, a waterproof ring is set in the outlet hole to improve the waterproof effect of the outlet position, and a plug cap is set on the outer periphery of the outlet portion. The plug cap can prevent the waterproof ring from falling out due to vibration, thereby avoiding waterproof failure. The matching use of the waterproof ring and the plug cap further improves the overall waterproof ability of the utility model.

[0011] Furthermore, the outer circumference of the waterproof ring is provided with a plurality of outer convex rings arranged at intervals, and the inner wall of the first through hole is provided with a plurality of inner convex rings arranged at intervals.

[0012] In the above technical solution, the outer convex rings arranged at intervals on the outer circumference of the waterproof ring can hug the inner wall of the wire outlet hole, making the connection between the waterproof ring and the wire outlet part tighter and more reliable. Similarly, a plurality of inner convex rings arranged at intervals on the inner wall of the first through hole can make the inner convex ring hug the wire harness tightly, making the connection between the waterproof ring and the wire harness tighter and more reliable.

[0013] Furthermore, the diameter of the wire outlet hole is smaller than the diameter of the outer convex ring, and the waterproof ring is interference-fitted with the inner wall of the wire outlet hole through the outer convex ring.

[0014] In the above technical solution, the diameter of the outlet hole is smaller than the diameter of the outer convex ring so that the waterproof ring can achieve interference fit with the outer convex ring through the inner wall of the outlet hole. Interference fit plays a vital role in mechanical installation. It uses the elasticity of the material to expand and deform the hole so that it can be sleeved on the shaft. When the hole returns to its original state, it will generate a clamping force on the shaft to ensure a tight connection between the two parts. The outlet part and the outer convex ring are interference fit, which makes the outlet part and the waterproof ring more compact and improves the overall waterproof effect.

[0015] Furthermore, the diameter of the inner convex ring is smaller than the diameter of the wiring harness, and the waterproof ring is interference-fitted with the wiring harness through the inner convex ring.

[0016] In the above technical solution, the diameter of the inner convex ring is smaller than the diameter of the wiring harness so that the waterproof ring can achieve an interference fit with the wiring harness through the inner convex ring. The interference fit between the wiring harness and the inner convex ring can make the connection between the wiring harness and the waterproof ring more compact, further improving the overall waterproof effect.

[0017] Furthermore, the diameter of the second through hole is smaller than the diameter of the wire outlet hole.

[0018] In the above technical solution, the baffle is used to limit the waterproof ring to prevent the waterproof ring from slipping out of the wire outlet hole due to vibration and affecting the waterproof effect. The purpose of the second through hole is only to allow the wire harness to pass through. The diameter of the second through hole is made smaller than the diameter of the wire outlet hole in order to better limit the waterproof ring and prevent the waterproof ring from slipping out of the wire outlet hole through the second through hole.

[0019] Furthermore, a surface of one side of the waterproof ring facing the plug cap is flush with a surface of the wire outlet hole.

[0020] In the above technical solution, in order to prevent water from entering the outlet hole and better improve the waterproof effect, the surface of the waterproof ring facing the plug cap is flush with the surface of the outlet hole, so that water cannot enter the outlet hole.

[0021] Furthermore, a plurality of limiting plates are provided on the periphery of the baffle, and the limiting plates are connected to the periphery of the outlet portion.

[0022] In the above technical solution, a plurality of limit plates are arranged on the periphery of the baffle, and the limit plates are arranged on the periphery of the outlet portion, so that the baffle can be stably connected to the outlet portion, ensuring that the plug cap can effectively prevent the waterproof ring from falling out during vibration.

[0023] Furthermore, a plurality of snap-fit ​​bosses are provided on the outer periphery of the wire outlet portion, and the limiting plate is provided with a plurality of snap-fit ​​sockets that cooperate with the snap-fit ​​bosses.

[0024] In the above technical solution, the snap-on boss and the snap-on socket are used to enable the limit plate to be stably connected to the wire outlet part. When the limit plate is connected to the wire outlet part, the snap-on boss and the snap-on socket are engaged to prevent the limit plate from loosening from the wire outlet part during vibration, thereby causing the plug cap to detach from the wire outlet part and affecting the waterproof effect.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] By arranging a waterproof ring at the wire outlet hole, the waterproof effect of the utility model is improved, while the space occupied by arranging the waterproof structure is reduced, and the utilization rate of the internal space of the shell is improved.

[0027] A plug cap is sleeved on the outer periphery of the outlet part. On the one hand, it can limit the waterproof ring through the plug cap to prevent the waterproof ring from falling out due to vibration, thereby ensuring the waterproof effect. On the other hand, it can prevent water erosion and improve the waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will further describe the novel antenna structure with waterproof function of the utility model in detail with reference to specific embodiments and drawings. The drawings show a preferred embodiment of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0036] Please refer to Figures 1 to 4 In a preferred embodiment, the novel antenna structure with waterproof function of the utility model includes:

[0037] A housing 1 having a cavity 101 therein;

[0038] The wire outlet portion 2 is provided on the housing 1, and the wire outlet portion 2 has a wire outlet hole 201 communicating with the cavity 101, and the wire outlet hole 201 is used for the wire harness 3 to pass through;

[0039] The waterproof ring 4 is disposed in the wire outlet hole 201, and the waterproof ring 4 has a first through hole 401 coaxial with the wire outlet hole 201; and

[0040] The plug cap 5 is sleeved on the outer periphery of the outlet portion 2 and includes a baffle 501 which abuts against a surface of the outlet hole 201 away from the cavity 101 and is provided with a second through hole 5011 opposite to the outlet hole 201 .

[0041] It can be seen from the above technical scheme that the utility model is provided with a shell 1, and a cavity 101 is provided in the shell 1. The cavity 101 is used to accommodate the internal components of the antenna, such as a PCB board, etc., to protect it from the influence of the external environment; by providing an outlet portion 2 on the shell 1, and providing an outlet hole 201 on the outlet portion 2 for the wire harness 3 for realizing the signal transmission of the antenna to pass through, the utility model only needs to waterproof the position of the outlet portion 2 when in use, which reduces the space occupied by the antenna in the prior art due to waterproofing, and improves the utilization rate of the internal space of the shell 1; at the same time, a waterproof ring 4 is provided in the outlet hole 201. The waterproof ring 4 can be used to fix and protect the wire harness on the one hand, and can also play a waterproof role on the other hand, thereby improving the waterproof effect of the outlet position; and a plug cap 5 is sleeved on the outer periphery of the outlet portion 201. The plug cap 5 can prevent the waterproof ring 4 from falling out due to vibration, thereby avoiding waterproof failure. The matching use of the waterproof ring 4 and the plug cap 5 further improves the overall waterproof ability of the utility model.

[0042] It should be noted that, in this embodiment, the shell 1 includes an upper shell and a lower shell, and the upper shell and the lower shell are ultrasonically welded by a closed loop ultrasonic line. Of course, other types of connection methods can also be used, as long as it is ensured that the upper shell and the lower shell can be tightly connected.

[0043] Please refer to Figure 5 The outer circumference of the waterproof ring 4 is provided with a plurality of spaced outer convex rings 402, and the inner wall of the first through hole 401 is provided with a plurality of spaced inner convex rings 403. The outer convex rings 402 spaced on the outer circumference of the waterproof ring 4 can increase the contact area between the waterproof ring 4 and the outlet hole 201, so that the connection between the waterproof ring 4 and the outlet part 2 is tighter and more reliable, and the waterproof effect is improved. The inner wall of the first through hole 401 is provided with a plurality of spaced inner convex rings 403, which can increase the friction between the waterproof ring 4 and the wire harness 3, and prevent the wire harness from loosening.

[0044] Specifically, the diameter of the outlet hole 201 is smaller than the diameter of the outer convex ring 402, and the waterproof ring 4 is interference fit with the inner wall of the outlet hole 403 through the outer convex ring 402. The diameter of the outlet hole 201 is smaller than the diameter of the outer convex ring 402, so that the waterproof ring 4 can achieve interference fit with the inner wall of the outlet part 2 and the outer convex ring 402. Interference fit plays a vital role in mechanical installation. It uses the elasticity of the material to expand and deform the hole so that it can be sleeved on the shaft. When the hole returns to its original state, it will generate a clamping force on the shaft to ensure a tight connection between the two parts. The inner wall of the outlet hole 201 and the outer convex ring 402 are interference fit, so that the outlet part 2 and the waterproof ring 4 are connected more compactly, which improves the overall waterproof effect of the utility model.

[0045] At the same time, the diameter of the inner convex ring 403 is smaller than the diameter of the wire harness 3, and the waterproof ring 4 is interference-fitted with the wire harness 3 through the inner convex ring 403. The diameter of the inner convex ring 403 is smaller than the diameter of the wire harness 3, so that the waterproof ring 4 can achieve interference fit with the wire harness 3 through the inner convex ring 403. The interference fit between the wire harness 3 and the inner convex ring 403 can make the connection between the wire harness 3 and the waterproof ring 4 more compact, further improving the overall waterproof effect.

[0046] Please refer to Figure 3 , the diameter of the second through hole 5011 is smaller than the diameter of the outlet hole 201. The baffle 501 is used to limit the waterproof ring 4 to prevent the waterproof ring 4 from slipping out of the outlet hole 201 due to vibration during vibration, affecting the waterproof effect. The purpose of the second through hole 5011 is only to allow the wire harness 3 to pass through. The diameter of the second through hole 5011 is smaller than the diameter of the outlet hole 201 in order to better limit the waterproof ring 4 and prevent the waterproof ring 4 from slipping out of the outlet hole through the second through hole 5011. At the same time, the outlet hole 201 and the second through hole 5011 form a stepped structure, which can effectively prevent moisture from intruding.

[0047] Please refer to Figure 4 , the surface of the waterproof ring 4 facing the plug cap 5 is flush with the surface of the outlet hole 201. In order to prevent moisture from entering the outlet hole 201 and better improve the waterproof effect, by making the surface of the waterproof ring 4 facing the plug cap 5 flush with the surface of the outlet hole 201, it can ensure that the waterproof ring 4 is closely attached to the outlet port 201, preventing moisture from penetrating from the gap between the waterproof ring 4 and the outlet hole 201.

[0048] Please refer to Figure 3 and Figure 4 A plurality of limit plates 502 are arranged on the periphery of the baffle 501, and the limit plates 502 are connected to the periphery of the outlet portion 2. A plurality of limit plates 502 are arranged on the periphery of the baffle 501, and the limit plates 502 are arranged on the periphery of the outlet portion 2, so that the baffle 501 can be stably connected to the outlet portion 2, ensuring that the plug cap 5 can effectively prevent the waterproof ring 4 from falling out during vibration.

[0049] Exemplarily, three limiting plates 502 are provided, which are respectively tightly fitted with the outer peripheral surface of the outlet portion 2 to ensure that the connection between the limiting plates 502 and the outlet portion 2 is tighter.

[0050] Specifically, a plurality of buckle bosses 202 are provided on the outer periphery of the outlet portion 2, and a plurality of bayonet holes 5021 are provided on the limiting plate 502 to match the buckle bosses 202. The buckle bosses 202 and the bayonet holes 5021 enable the limiting plate 502 to be stably connected to the outlet portion 2. When the limiting plate 502 is connected to the outlet portion 2, the buckle bosses 202 and the bayonet holes 5021 are engaged to prevent the limiting plate 502 from being loosened from the outlet portion 2 during vibration, thereby causing the plug cap 5 to be separated from the outlet portion, affecting the waterproof effect.

[0051] During the assembly process, the waterproof ring 4 is first inserted into the outlet hole 201, and then the wire harness 3 is passed through the first through hole 401 of the waterproof ring 4 and the second through hole 5011 of the plug cap 5. Finally, the plug cap 5 is sleeved on the outer periphery of the outlet portion 2 and fixed by the cooperation of the buckle boss 202 and the bayonet 5021. This structure enables the antenna to maintain good waterproof performance even in harsh environments, ensuring the stability and reliability of communication.

[0052] The utility model provides a novel antenna structure with waterproof function, which realizes high waterproof performance of the antenna through special waterproof design, ensures the stability and reliability of the antenna, and provides strong support for the development of wireless communication technology.
