Description

Technical Field

[0001] This utility model relates to the field of antenna technology, specifically a waterproof single Beidou GMOUSE antenna. Background Technology

[0002] As is generally known, a GMOUSE antenna is an integrated GNSS receiver terminal, which typically includes a high-sensitivity antenna, a signal amplification module, and a standardized interface. It is mainly used in vehicle-mounted, industrial, and other scenarios that require high-precision positioning.

[0003] For example, the utility model patent with application announcement number CN218569211U, application publication date of March 3, 2023, and title "An Anti-interference GPS Antenna Structure" has an antenna structure that includes a shell, magnet, PCB circuit board, antenna vibrator, guide hole, GMOUSE extension cable, connector, wire hole, clearance groove, blocking plate, foam, shielding cover, plastic shell, connecting cover, handle and hinge.

[0004] The shortcoming of the existing technology is that the GMOUSE extension cable is electrically connected to the connector inside the housing through the wire hole on the housing, and glue is often applied at the wire hole to seal the wire hole between the extension cable and the housing. However, when the sealant is directly exposed to the outside, the glue is easily affected by factors such as temperature, ultraviolet rays, ozone and humidity, which can cause the molecular chain to break, resulting in cracking or powdering of the glue, thus causing the seal at the wire hole to fail. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figure 1 and Figure 2 As shown, this embodiment provides an additional sealing structure, namely a flexible cover 4, on the basis of the original antenna. After the extension line 2 passes through the through post 22 and connects to the housing 1, adhesive is applied to the through post 22. Then, the flexible cover 4 can be fitted from the end of the extension line 2, and the flexible cover 4 is deformed and passes over the fixing seat 3. At this time, the flexible cover 4 is coaxially fitted on the fixing seat 3 and the through post 22, thereby wrapping and protecting the through post 22 and the tail end of the extension line 2 that is close to the housing 1, thereby reducing the speed at which the adhesive at the through post 22 cracks or powders due to external environmental factors, and improving the sealing stability at the through post 22.

[0028] Specifically, a connection end 21 is fixedly connected to the end of the extension line 2. Inside the housing 1, there is a high-performance BD receiver integrated module, a ceramic body, and a low-noise amplifier. When the extension line 2 passes through the post 22 and connects to the housing 1, the inside of the post 22 still needs to be sealed with adhesive. The high-performance BD receiver integrated module, ceramic body, and low-noise amplifier are common technical knowledge to those skilled in the art and will not be described in detail here.

[0029] In the above technical solution, the flexible cover 4 is coaxially sleeved on the fixed base 3 and the through column 22, thereby wrapping and protecting the tail end of the through column 22 and the extension line 2 that is close to the housing 1, thereby reducing the speed at which the colloid at the through column 22 cracks or pulverizes due to external environmental factors, and improving the sealing stability at the through column 22.

[0030] Example 2

[0031] Combination Figure 1 and Figure 2As shown, this embodiment provides an additional fixing structure for the flexible cover 4, namely a deformation ring 5 and a fixing ring 6, based on embodiment one. When the flexible cover 4 is fitted onto the fixing base 3 and the through post 22, the outer ring side of the deformation ring 5 can deform to press the flexible cover 4 onto the fixing base 3, while the fixing ring 6 presses the deformation ring 5 onto the through post 22, thereby improving the installation stability of the flexible cover 4 on the fixing base 3 and the through post 22, and also further improving the shielding and sealing protection effect of the flexible cover 4 on the extension line 2 and the through post 22.

[0032] Specifically, such as Figure 2 As shown, the right end of the flexible cover 4 is the first end, and the left end of the flexible cover 4 is the second end. The inner ring side of the deformation ring 5 is glued to the fixing base 3.

[0033] Example 3

[0034] Combination Figure 2 and Figure 4 As shown, this embodiment further improves upon embodiment two by creating a limiting groove 23 on the through post 22 and a ring groove 4 on the flexible cover 4. When the deformation ring 5 and the fixing ring 6 press and fix the end of the flexible cover 4, both the deformation ring 5 and the fixing ring 6 abut against the ring groove 41 to improve the stability of the flexible cover 4 on the fixing seat 3 and the through post 22.

[0035] Example 4

[0036] Combination Figure 2 As shown, this embodiment further improves the flexible cover 4 based on embodiment one. Specifically, several abutment rings 42 are provided inside the flexible cover 4, which are perpendicular to the axis of the flexible cover 4 in the default state. When the flexible cover 4 is sleeved from the end of the extension line 2, the abutment rings 42 are squeezed by the fixing seat 3 and deformed on the inner ring side towards the fixing seat 3, and then abut against the outside of the extension line 2. At this time, the flexible cover 4 is coaxially sleeved on the fixing seat 3 and the through post 22, and the abutment rings 42 abut against the outer surface of the extension line 2 in an inclined position. The abutment rings 42 have elastic potential energy for reset and apply axial pressure to the extension line 2 towards the through post 22, thereby reducing the tension on the extension line 2 towards the outside of the through post 22 during installation and improving the protection of the extension line 2.

[0037] Specifically, the contact ring 42 and the flexible cover 4 are integrally formed.

[0038] Example 5

[0039] Combination Figure 2 and Figure 3As shown, this embodiment further improves upon embodiment four by pre-embedding multiple sets of deformation plates 7 within the flexible cover 4. These deformation plates 7 enhance the support of the flexible cover 4, thereby improving its protective function against the extension line 2 and the through column 22. Secondly, as... Figure 3 As shown, a single deformable piece 7 can be pressed to cause the center of the deformable piece 7 to arch towards the axis of the flexible cover 4. At this time, the deformed piece 7 applies a bending force to the flexible cover 4, thereby allowing the flexible cover 4 to maintain its bent state. Therefore, by pressing multiple deformable pieces 7 at different positions, the axis of the flexible cover 4 can be bent, allowing the extension line 2 inside the flexible cover 4 to be bent and laid out according to the installation requirements, further improving the protection of the extension line 2.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
