Description

Technical Field

[0001] This utility model relates to the field of conformal antenna integration structure, and in particular to a conformal antenna integration structure for vehicle-mounted GPS and 4G modules. Background Technology

[0002] Conformal antenna integrated structure is a technical solution that integrates the antenna radiating element with the carrier structure. Its core feature is that the antenna no longer exists as an independent additional component, but is deeply integrated with the geometric shape, structural function of the carrier. While meeting the basic requirements of carrier aerodynamic performance, mechanical strength, and spatial constraints, it achieves efficient electromagnetic signal radiation and reception.

[0003] For the positioning and installation of conformal antennas, the pre-set installation reference point on the vehicle body is usually used as a reference to achieve initial centering through plastic positioning clips or metal positioning pins to avoid antenna offset affecting the GPS signal reception angle. For scenarios requiring a stable connection, a low dielectric constant insulating gasket is used, and a threaded rod is used for positioning and tightening. During installation, the threaded rod is first passed through the positioning hole of the antenna base, aligned with the pre-set internal thread hole on the vehicle body, and manually pre-tightened to achieve coarse positioning. Then, a torque wrench is used to tighten in stages, while applying an insulating thread-locking agent to the threads.

[0004] During the installation of conformal antenna integrated structures, the spacing of the pre-set threaded holes often deviates due to the processing precision of the pre-set threaded holes on the body sheet metal of different vehicle models and the differences in vehicle platform. The positioning holes of existing conformal antenna integrators are mostly designed with fixed diameter and fixed spacing, which is not convenient to flexibly adjust according to the actual spacing of the threaded holes. This leads to the problem of misalignment between the positioning holes and the threaded holes during installation, requiring additional processing of adapter holes, which significantly reduces the installation compatibility range and increases the vehicle model compatibility cost and installation time. To address this issue, a conformal antenna integrated structure for vehicle GPS and 4G modules is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a conformal antenna integration structure for vehicle GPS and 4G modules, aiming to solve the problem in the prior art where the positioning hole of the vehicle conformal antenna integrator is fixed and cannot adapt to the deviation of the pre-set threaded hole spacing of different vehicle body sheet metal, which easily leads to misalignment of the positioning hole and the threaded hole during installation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a conformal antenna integration structure for vehicle-mounted GPS and G modules, comprising a conformal antenna integrator, wherein the bottom of the conformal antenna integrator is provided with an adjustment self-locking mechanism and an adjustment moving mechanism, the adjustment self-locking mechanism comprising a support frame, the top of the support frame being fixedly connected to the bottom of the conformal antenna integrator, a bidirectional screw being rotatably connected to the inner wall of the support frame, a translation block being threadedly connected to the outer wall of the bidirectional screw through a threaded sleeve, a support plate being fixedly connected to the bottom of the translation block, a fixed cylinder being fixedly connected to the left side of the support frame, a limit tooth being fixedly connected to the inner wall of the fixed cylinder, a cross rotating rod being fixedly connected to the left end of the bidirectional screw, a cross rotating cylinder being elastically connected to the outer wall of the cross rotating rod through a spring, the inner wall of the cross rotating cylinder being slidably connected to the outer wall of the cross rotating rod, and a gear being fixedly connected to the left end of the cross rotating cylinder.

[0007] As a further description of the above technical solution:

[0008] The self-locking adjustment mechanism also includes a knob, the right end of which is fixedly connected to the left end of the cross-shaped rotating cylinder.

[0009] As a further description of the above technical solution:

[0010] The self-locking adjustment mechanism also includes a limiting slide groove, which is formed on the outer wall of the support plate.

[0011] As a further description of the above technical solution:

[0012] The self-locking adjustment mechanism also includes a slider, the outer wall of which is slidably connected to the inner wall of the limiting groove.

[0013] As a further description of the above technical solution:

[0014] The self-locking adjustment mechanism also includes an L-shaped positioning block, which is detachably connected to the side wall of the slider via a threaded rod.

[0015] As a further description of the above technical solution:

[0016] The self-locking adjustment mechanism also includes a positioning hole, which is formed on the outer wall of the L-shaped positioning block.

[0017] As a further description of the above technical solution:

[0018] One end of the spring is fixedly connected to the outer wall of the cross-shaped rotating rod, and the other end of the spring is fixedly connected to the outer wall of the cross-shaped rotating cylinder.

[0019] As a further description of the above technical solution:

[0020] The adjusting and moving mechanism includes a second bidirectional screw, the outer wall of which is rotatably connected to the inner wall of the limiting slide groove.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the bidirectional screw is threadedly connected to the inner wall of the slider via a threaded sleeve.

[0023] As a further description of the above technical solution:

[0024] The adjustment and movement mechanism also includes a second knob, the outer wall of which is fixedly connected to one end of the bidirectional screw.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, by setting an adjustment self-locking mechanism, the position of the positioning hole can be flexibly adjusted according to the different lateral spacing of the preset threaded holes, which improves the installation and adaptation range of the conformal antenna integrator. After adjustment, it can effectively prevent the bidirectional screw from rotating due to vibration, external force and other factors during subsequent installation and tightening or long-term use, and avoid the conformal antenna integrator from affecting signal reception due to loose positioning.

[0027] 2. In this utility model, by setting an adjustment and moving mechanism, the L-shaped positioning block moves within the inner wall of the limiting slide groove. The limiting slide groove can strictly guide and constrain the movement trajectory of the L-shaped positioning block, preventing it from shifting left or right or wobbling up or down during longitudinal adjustment. This ensures that the positioning hole always moves in a straight line along the longitudinal direction, further guaranteeing the alignment accuracy with the preset threaded hole and reducing installation errors.

[0037] Reference Figures 1-3The present invention provides an embodiment of a conformal antenna integration structure for a vehicle-mounted GPS and 4G module, comprising a conformal antenna integrator 1. The conformal antenna integrator 1 is the core component of the entire integrated structure, used to integrate the antenna functions of the vehicle-mounted GPS and 4G modules. The bottom of the conformal antenna integrator 1 is provided with an adjustment self-locking mechanism 2 and an adjustment moving mechanism 3. The adjustment self-locking mechanism 2 is used to adjust and lock the lateral horizontal position of the L-shaped positioning block 224, and the adjustment moving mechanism 3 is used to adjust the longitudinal horizontal position of the L-shaped positioning block 224. The adjustment self-locking mechanism 2 includes a support frame 211, which provides a mounting support base for the bidirectional screw 212. The top of the support frame 211 is fixedly connected to the bottom of the conformal antenna integrator 1. The bidirectional screw 212 is rotatably connected to the inner wall of the support frame 211. When the bidirectional screw 212 rotates, it can drive two translation blocks 213 to move closer or further apart through threaded transmission. The translation blocks 213 are threadedly connected to the outer wall of the bidirectional screw 212 through threaded sleeves. The movement of the translation blocks 213 can drive the support plate 214 to move synchronously. A support plate 214 is fixedly connected to the bottom of the translation block 213. The support plate 214 provides an installation carrier for the limiting slide groove 222 and the slider 223. A fixed cylinder 215 is fixedly connected to the left side of the support frame 211. The fixed cylinder 215 provides a fixed installation space for the limiting tooth 216. The limiting tooth 216 is fixedly connected to the inner wall of the fixed cylinder 215. The limiting tooth 216 can mesh with the gear 220 to achieve rotation locking of the bidirectional screw 212. A cross rod 217 is fixedly connected to the left end of the bidirectional screw 212. The cross rod 217 can... The bidirectional screw 212 rotates synchronously and can slide on the inner wall of the cross cylinder 218. The outer wall of the cross rod 217 is elastically connected to the cross cylinder 218 via a spring 219. The cross cylinder 218 can drive the gear 220 to move and achieve engagement or disengagement with the limiting teeth 216. The inner wall of the cross cylinder 218 is slidably connected to the outer wall of the cross rod 217. The gear 220 is fixedly connected to the left end of the cross cylinder 218. The gear 220 cooperates with the limiting teeth 216 to achieve rotational limitation of the cross cylinder 218 and the cross rod 217.

[0038] Reference Figures 4-6The self-locking mechanism 2 also includes a knob 221, which allows the operator to apply force to rotate and move the cross cylinder 218. The right end of the knob 221 is fixedly connected to the left end of the cross cylinder 218. The self-locking mechanism 2 also includes a limiting groove 222, which provides guidance and limiting for the movement of the slider 223. The limiting groove 222 is located on the outer wall of the support plate 214. The self-locking mechanism 2 also includes a slider 223, which can drive the L-shaped positioning block 224 to move within the limiting groove 222. The outer wall of the slider 223 is slidably connected to the inner wall of the limiting groove 222. The self-locking mechanism 2 also includes an L-shaped positioning block. 224, the L-shaped positioning block 224 achieves the positioning and installation of the conformal antenna integrator 1 through the positioning hole 225 and the bolt. The L-shaped positioning block 224 is detachably connected to the side wall of the slider 223 through the threaded rod. The self-locking adjustment mechanism 2 also includes a positioning hole 225. The positioning hole 225 is used to insert the bolt and cooperate with the preset threaded hole to achieve positioning. The positioning hole 225 is opened on the outer wall of the L-shaped positioning block 224. One end of the spring 219 is fixedly connected to the outer wall of the cross rotating rod 217, and the other end of the spring 219 is fixedly connected to the outer wall of the cross rotating cylinder 218. The spring 219 can drive the cross rotating cylinder 218 to reset through its own rebound force so that the gear 220 re-engages with the limiting tooth 216.

[0039] Reference Figure 6 The adjusting and moving mechanism 3 includes a bidirectional screw 311. When the bidirectional screw 311 rotates, it can drive the slider 223 to move within the limiting groove 222 through threaded transmission. The outer wall of the bidirectional screw 311 is rotatably connected to the inner wall of the limiting groove 222. The outer wall of the bidirectional screw 311 is threadedly connected to the inner wall of the slider 223 through a threaded sleeve. The adjusting and moving mechanism 3 also includes a knob 312. The knob 312 is convenient for the operator to apply force to rotate and drive the bidirectional screw 311 to rotate. The outer wall of the knob 312 is fixedly connected to one end of the bidirectional screw 311.

[0040] Working principle: When the conformal antenna integrator 1 needs to be positioned and installed, first observe the position of the preset threaded hole, then press knob 221. Knob 221 drives gear 220 and cross cylinder 218 to move, compressing spring 219. This causes gear 220 to no longer mesh with the limiting teeth 216 on the inner wall of the fixed cylinder 215. Then, by rotating knob 221, knob 221 drives cross cylinder 218 to move via gear 220. This then drives cross rod 217, which is slidably connected to the inner wall of cross cylinder 218, to rotate. 217 drives the bidirectional screw 212 to move, causing the two translation blocks 213 connected by the threaded sleeve on the outer wall of the bidirectional screw 212 to move closer to each other. The translation blocks 213 drive the L-shaped positioning block 224 to move through the support plate 214, thereby adjusting the horizontal position of the positioning hole 225 according to the position of the preset threaded hole. After the adjustment is completed, the knob 221 can be released, and the rebound force of the spring 219 can reset the cross cylinder 218, so that the gear 220 re-meshes with the limiting teeth 216, thereby locking the bidirectional screw 212 to rotate.

[0041] When it is necessary to adjust the longitudinal horizontal position of the L-shaped positioning block 224, the knob 312 can be rotated to drive the bidirectional screw 311 to rotate, so that the L-shaped positioning block 224, which is connected to the outer wall of the bidirectional screw 311 by the threaded sleeve, moves in the inner wall of the limiting slide groove 222, thereby adjusting the longitudinal horizontal position of the positioning hole 225 according to the position of the preset threaded hole.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
