Description

Technical Field

[0001] This utility model relates to the field of antennas, and in particular to an antenna with side-exit wires. Background Technology

[0002] The applicant filed a utility model patent application on April 7, 2024, with application number CN202420693221.0, entitled "A Vehicle-Mounted Waterproof High-Precision Satellite Positioning Antenna." In this technical solution, the sides of the housing and cover are respectively provided with an upper and lower cable exit section through which the power supply line passes. A stepped section is provided on the inner wall of the housing, and an annular plate is also provided on the housing located inside the stepped section. The upper cable exit section passes through the stepped section and the annular plate. The cover is provided with an annular groove plate that abuts against the aforementioned annular plate and has an annular groove at its top. The lower cable exit section passes through the annular groove plate. When the housing and cover are fastened together, the stepped section of the housing and the edge of the cover, the annular plate and the annular groove plate, and the upper and lower cable exit sections respectively form a first, second, and third ultrasonic welding zone, thereby improving the antenna's waterproof performance. However, this technology has the following technical problems during use: First, the area of ​​the third ultrasonic welding zone between the upper and lower cable exit sections is small and isolated from other ultrasonic welding areas, resulting in poor structural strength around the cable exit hole. Furthermore, the antenna cable is frequently subjected to tensile stress during use, making this area prone to cracking over time. This allows moisture to easily seep into the antenna body, corroding it and shortening its lifespan.

[0003] Secondly, the presence of the annular water-retaining groove results in a lack of support on the inner side of the first ultrasonic welding area and on both sides of the second ultrasonic welding area, leading to poor impact resistance in these two areas. During use, antenna products inevitably experience accidents such as drops from heights or impacts. Due to the lack of support, these two ultrasonic welding areas are prone to vibration, causing cracks and resulting in poor reliability and durability of the antenna product, leading to higher user costs.

[0004] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide an antenna product with better sealing performance and more stable performance. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and deficiencies, and to provide an IP67 waterproof external antenna with side-exit wiring. This is achieved by setting a double-layer ultrasonic welding line at the upper wire exit notch, where the double-layer ultrasonic welding line merges with the ultrasonic welding line on the inner annular step, and by forming a stepped, folded ultrasonic welding line with varying heights between the double-layer ultrasonic welding lines. This significantly enhances the structural strength around the wire exit hole. Furthermore, by setting a tightly fitted outer edge and an inner annular step on the housing, and a tightly fitted outer protruding edge and inner annular edge on the bottom cover, both the inner and outer sides of the ultrasonic welding area are supported, thereby improving the antenna's impact resistance, durability, and reliability.

[0006] The technical solution of this utility model is implemented as follows: an IP67 waterproof external antenna with side-mounted wiring, characterized in that it includes: a housing with an upper wiring notch on one side; the housing is surrounded by an outer interlocking edge and an inner annular step that is close to the inner side of the outer interlocking edge and has a vertical height lower than the outer interlocking edge; the upper wiring notch is also provided with a double-layer ultrasonic welding line, the two sides of the double-layer ultrasonic welding line extending towards the inner annular step and converging with the ultrasonic welding line provided on the inner annular step; a layer of ultrasonic welding line is also formed between the double-layer ultrasonic welding line and the ultrasonic welding line. The device includes a stepped, pleated ultrasonic welding line with varying heights; a bottom cover with a thickened lower lead-out section on one side; the bottom cover is surrounded by an outer raised edge and an inner annular edge with a vertical height higher than the outer raised edge; the thickened lower lead-out section connects to the outer raised edge on both sides, and a stepped, pleated section with varying heights is formed between the thickened lower lead-out section and the outer raised edge; and an antenna body with a wire on one side, which is housed in the inner cavity formed by the housing and the bottom cover, with the wire extending from between the upper lead-out notch and the lower lead-out thickened section.

[0007] Furthermore, the thickened lower lead-out section and the notched upper lead-out section are each provided with a large sealing ring fitting cavity that can be connected to each other.

[0008] Furthermore, the thickened lower wire outlet portion and the notched upper wire outlet portion are respectively provided with small sealing ring fitting grooves that can be mated together on the side of the large sealing ring fitting cavity.

[0009] Furthermore, the thickness H of the lower lead-out thickened portion is greater than the sum of the thickness L of the outer convex edge and the inner annular edge.

[0010] Furthermore, the housing and the bottom cover are respectively provided with cavities for accommodating the antenna body.

[0011] Furthermore, the cavity of the shell is provided with an annular vertical plate and an annular step, the inner diameter of the annular step being smaller than the inner diameter of the annular vertical plate.

[0012] Furthermore, the annular step is also provided with multiple convex protrusions arranged at equal intervals.

[0013] Furthermore, the antenna body consists of a base plate, a stepped cover mounted on the base plate and fitted into the recessed cavity with an annular vertical plate and an annular step, and a patch antenna mounted between the base plate and the stepped cover.

[0014] Furthermore, the top surface of the stepped cover is also provided with a buffer rubber particle section.

[0015] Furthermore, the bottom cover cavity is provided with a support boss, and the top surface of the support boss is provided with a buffer rubber particle part.

[0016] The beneficial effects of this utility model are: First, the double-layer ultrasonic welding line at the upper wire outlet notch of the housing significantly increases the ultrasonic welding area around the wire outlet hole of the antenna product. Furthermore, the double-layer ultrasonic welding line extends inwards to form annular steps on both sides, converging with the ultrasonic welding line on the inner annular step. This connects the ultrasonic welding area around the wire outlet hole with the ultrasonic welding area on the inner annular step, forming a closed-loop ultrasonic welding area with the wire outlet hole inside the antenna product. Additionally, stepped, pleated ultrasonic welding lines with varying heights are formed between the double-layer ultrasonic welding lines, further increasing the area of ​​the ultrasonic welding region and allowing for a more secure connection between the housing and the bottom cover. These technical means ensure a very strong ultrasonic weld around the wire outlet hole, preventing cracks even when the wire is frequently stretched, greatly improving the product's reliability and stability.

[0017] Secondly, by setting an outer interlocking edge and an inner annular step that fit closely together on the housing, and setting an outer protruding edge and an inner annular edge that fit closely together on the bottom cover, when the housing and bottom cover are assembled together, the outer protruding edge and stepped fold on the bottom cover fit closely against the outer interlocking edge on the housing and are embedded in the housing. At the same time, the outer protruding edge and the inner annular step abut together to form an ultrasonic welding zone, and the stepped fold and the stepped fold ultrasonic welding line abut together to form an ultrasonic welding zone. The outer side of the two ultrasonic welding zones is supported by the outer protruding edge, and the inner side is supported by the inner annular edge, thereby greatly improving the impact resistance of the antenna product. Even if the antenna product is bumped or dropped, these two ultrasonic welding zones are not prone to cracking, thus maintaining excellent waterproof performance for a long time, making the antenna product more durable and reliable.

[0018] Through the above-mentioned technical means, the antenna product of this utility model can achieve a waterproof rating of IP67, and can be used safely and reliably in outdoor scenarios such as vehicle roofs and cabinet tops. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1 to 6As shown, this utility model provides an IP67 waterproof external antenna with side-mounted wiring. To achieve the purpose proposed by this utility model, a housing 1 with a side-mounted wiring notch 11 is provided. The housing 1 is composed of an outer interlocking edge 12 and an inner annular step 13 that is close to the inner side of the outer interlocking edge 12 and is shorter in height than the outer interlocking edge 12. The upper wiring notch 11 is also provided with a double-layer ultrasonic welding line 4. The two sides of the double-layer ultrasonic welding line 4 extend towards the inner annular step 13 and converge with the ultrasonic welding line 5 provided on the inner annular step 13. Stepped sections with varying heights are provided on both sides of the upper wiring notch 11, and ultrasonic lines are arranged on these stepped sections, thus forming a height difference between the double-layer ultrasonic welding line 4 and the ultrasonic welding line 5. The system includes a stepped, pleated ultrasonic welding line 6, which connects the double-layer ultrasonic welding line 4 and the ultrasonic welding line 5; a bottom cover 2 with a lower lead-out thickened portion 21 on one side; the bottom cover 2 is composed of an outer raised edge 22 and an inner annular edge 23 with a vertical height higher than the outer raised edge 22; the lower lead-out thickened portion 21 is connected to the outer raised edge 22 on both sides, and a stepped, pleated portion 20 with a height difference is formed between the lower lead-out thickened portion 21 and the outer raised edge 22; and an antenna body 3 with a wire 31 on one side, which is placed in the inner cavity formed by the housing 1 and the bottom cover 2, with the wire 31 extending from between the upper lead-out notch 11 and the lower lead-out thickened portion 21.

[0028] During assembly, the outer raised edge 22 and stepped folded portion 20 on the bottom cover 2 are tightly fitted against the inner side of the outer embedded edge 12 on the housing 1, respectively abutting against the ultrasonic welding line 5 and the stepped folded ultrasonic welding line 6 on the inner annular step 13 to form an ultrasonic welding area. Simultaneously, the lower wire extension thickened portion 21 abuts against the double-layer ultrasonic welding line 4 on the upper wire extension notch 11 to form a double-structured ultrasonic welding area. Through these designs, a closed-loop ultrasonic welding area with a wire extension hole is formed inside the antenna product. The entire ultrasonic welding area is not only larger but also interconnected, resulting in a very strong ultrasonic welding structure, especially around the wire extension hole, where the ultrasonic welding strength is high, and even with frequent wire pulling, cracks are not easily formed. Furthermore, as... Figure 6 As shown, the outer interlocking edge 12 and the inner annular edge 23 provide support to the ultrasonic welding area from the outside and inside, respectively. This prevents the ultrasonic welding area from cracking due to impact when it encounters a collision, further enhancing the overall impact resistance of the antenna product. At the same time, the inner annular edge 23 can also support the side wall of the housing 1, further improving the mechanical strength of the housing 1, thereby improving the compressive strength and impact resistance of the antenna product.

[0029] Through the above-mentioned technical means, the antenna product of this utility model can achieve a waterproof rating of IP67, which can effectively prevent dust and moisture from corroding the internal antenna body 3, making the product suitable for relatively harsh environments.

[0030] like Figure 3 , 5 As shown, the lower wire extension thickened portion 21 and the upper wire extension notch portion 11 are also respectively provided with large sealing ring fitting cavities 7 that can be mated together. In this way, by installing a sealing ring in the large sealing ring fitting cavity 7, not only can the wire extension hole of the antenna product be sealed to prevent moisture from seeping into the antenna product, but the tensile strength of the wire extension hole can also be further enhanced to prevent cracks from forming at that point.

[0031] Furthermore, such as Figure 3 , 5 As shown, the lower lead-out thickened portion 21 and the upper lead-out notch portion 11 are respectively provided with small sealing ring fitting grooves 8 that can be mated together on the side of the large sealing ring fitting cavity 7. In this way, the double-layer sealing ring configuration can further enhance the sealing performance and tensile strength of the wire protrusion hole.

[0032] like Figure 3 As shown, the thickness H of the lower lead-out thickened portion 21 is greater than the sum L of the thicknesses of the outer convex edge 22 and the inner annular edge 23. This makes the material at the wire protrusion hole thicker, and the ultrasonic welding area formed between the lower lead-out thickened portion 21 and the upper lead-out notch 11 is also larger, thereby helping to further improve the structural strength at this point, and thus ensuring that this point has very good impact resistance and sealing performance.

[0033] like Figure 2 , 4 As shown in Figure 6, the housing 1 and the bottom cover 2 are each provided with a recess 9 for accommodating the antenna body 3. When the housing 1 and the bottom cover 2 are fastened together, the two recesses 9 are connected to form an inner cavity for accommodating the antenna body 3. At the same time, the upper wire exit notch 11 and the lower wire exit thickened part 21 are respectively provided with half wire exit holes, and the two half wire exit holes form wire exit holes for the power supply wire to extend out.

[0034] like Figure 4 , 5 As shown in Figure 6, the cavity 9 of the housing 1 is further provided with an annular vertical plate 91 and an annular step 92, respectively. The inner diameter of the annular step 92 is smaller than the inner diameter of the annular vertical plate 91. This forms an annular isolation groove 910 between the annular vertical plate 91 and the shell wall of the housing 1, which can block the transmission of vibrations from the shell wall to the antenna body 3, further improving the impact resistance and shock resistance of this invention, and providing better protection for the antenna body. Even in the event of a severe impact, the antenna body 3 can still operate stably.

[0035] like Figure 5 , 6 As shown, the annular step 92 is also provided with a plurality of equally spaced locking protrusions 93. These locking protrusions 93 can provide support, thereby enhancing the mechanical strength of the annular vertical plate 91 and further enhancing the structural stability of this utility model.

[0036] like Figure 2 , 6 As shown, the antenna body 3 consists of a base plate 32, a stepped cover 33 mounted on the base plate 32 and fitted into the recess 9 with an annular vertical plate 91 and an annular step 92, and a patch antenna disposed between the base plate 32 and the stepped cover 33. This allows the antenna body 3 to be securely fitted into the recess 9, resulting in a more compact and robust structure.

[0037] like Figure 2 As shown, the top surface of the stepped housing 33 is also provided with buffer rubber particles 10. These buffer rubber particles 10 can absorb vibrations on the housing 1, thereby further protecting the antenna body 3.

[0038] like Figure 2 , 7 As shown, the recessed cavity 9 of the bottom cover 2 is also provided with a support boss 94, and the top surface of the support boss 94 is also provided with a buffer rubber part 10. These buffer rubber parts 10 can further absorb the vibration on the bottom cover 2, and further protect the antenna body 3. At the same time, a groove 24 for accommodating a magnetic component is also integrally formed on the outer bottom of the bottom cover 2, so as to facilitate the direct installation of the antenna product on the roof of the car by magnetic attraction.

[0039] To facilitate fixing the antenna to the surface of an object, such as Figure 1 As shown, lugs 14 are provided on both sides of the housing 1.
