Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, specifically a self-adjusting sliding cover mounting structure. Background Technology

[0002] In the field of vehicle equipment, sliding covers are typically installed on the top of vehicles to support and retract antennas, meeting the height and protection requirements of communication antennas during driving, parking, and various operating conditions. When vehicles are traveling at high speeds, passing through height-restricted areas, or entering storage or transportation environments, the antennas need to be retracted and covered and protected by the sliding cover; while in communication, command, or operational states, the antennas need to be easily deployed by opening the sliding cover.

[0003] Due to factors such as vehicle body styling, welding assembly, and reinforcement arrangement, the mounting surfaces of the left and right guide rails on the vehicle's roof structure are often difficult to ensure are on the same plane, easily leading to height differences, twisting, or reference offsets. Therefore, the sliding cover mounting structure is required to adapt to non-coplanar mounting conditions and ensure reliable antenna deployment and retrieval. However, in existing sliding cover structures, the cover is usually rigidly mounted on the guide rails on both sides, requiring high parallelism, straightness, and surface flatness of the guide rails. When there is a parallelism deviation in the installation of the left and right guide rails, or when the guide rail surface develops local protrusions or depressions due to processing, welding deformation, or long-term use, the cover is prone to uneven force, increased resistance, or even jamming during sliding, seriously affecting the normal deployment and retrieval of the antenna. At the same time, traditional structures lack effective adaptive adjustment and buffering capabilities. Once the guide rail conditions change, recalibration or complete disassembly and reassembly is often required, which is not only inconvenient to maintain but also has poor reliability, making it difficult to meet the requirements of smooth and stable operation of the cover under complex environments and long-term use conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a self-adjusting sliding cover mounting structure to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A self-adjusting sliding cover mounting structure is provided, including a vehicle body. Guide rail adjustment components are provided on both sides of the vehicle body. A sliding guide rail is provided on the guide rail adjustment components. A slider body is provided on the sliding guide rail. A floating mounting seat is provided above the slider body. Radial limiting components are provided on both sides of the floating mounting seat and the slider body. Vertical limiting components are also provided around the floating mounting seat and the slider body. The floating mounting seat is connected to the sliding cover body through a fixing component.

[0006] Furthermore, the radial limiting component includes a mounting plate, which is disposed on a floating mounting base. A limiting groove is provided in the mounting plate, and a limiting shaft is provided in the limiting groove. The limiting shaft is disposed between the floating mounting base and the mounting plate, and an elastic buffer is sleeved on the outside of the limiting shaft.

[0007] Furthermore, a pre-tightening screw is provided on one side of the mounting plate, and the pre-tightening screw abuts against the limiting shaft.

[0008] Furthermore, the radial limiting component includes a support component, which is disposed on the floating mounting base, and an elastic support member is sleeved below the support component, which is disposed between the floating mounting base and the slider body.

[0009] Furthermore, the support assembly includes a support rod body, which is mounted on a floating mounting base. A limiting step is provided on one side of the upper part of the support rod body, and an elastic support member is sleeved on the limiting step.

[0010] Furthermore, the elastic support includes a cylindrical spring, the upper side of which is sleeved on the limiting step, and a guide pin is provided at the lower part of the cylindrical spring, the guide pin being detachably connected to the slider body.

[0011] Furthermore, the fixing component includes a mounting plate with several adjustment slots and fastening bolts in the adjustment slots. The mounting plate is detachably connected to the floating mounting base by the fastening bolts.

[0012] Furthermore, the guide rail adjustment assembly includes a guide rail adjustment plate, which is slidably connected above the vehicle body. An adjustment screw is fixedly connected to one side of the upper part of the guide rail adjustment plate, and the adjustment screw is rotatably connected to the vehicle body.

[0013] Furthermore, several reset springs are also provided between the guide rail adjusting plates.

[0014] Furthermore, an inspection port is provided on the top of the sliding cover body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This structure reduces the impact of left and right guide rail installation errors on the sliding cover's operation by incorporating guide rail adjustment components on both sides of the vehicle body. This allows the sliding guide rails to be initially positioned relative to the vehicle body, thus mitigating the impact of left and right guide rail installation errors on the sliding cover's operation. The slider body is mounted on the sliding guide rail, with a floating mounting seat above it. This eliminates the rigid connection between the sliding cover body and the slider, giving it a degree of self-adaptive floating capability. Radial limiting components on both sides of the floating mounting seat and the slider body allow for slight horizontal displacement of the floating mounting seat, compensating for guide rail parallelism errors and lateral deviations. Simultaneously, elastic preload maintains centered force, reducing the impact of uneven axial force. The floating mounting base and the vertical limiting components around the slider body provide elastic support and limiting guidance in the vertical direction, allowing the floating mounting base to absorb the effects of local protrusions or height changes on the sliding guide surface. This prevents the slider body from jamming due to vertical jamming during operation. The fixing components stably mount the slider body on the floating mounting base, ensuring the overall rigidity and load-bearing capacity of the slider body while keeping it in a state of force balance during sliding. This enables the slider body to self-adjust and run smoothly under non-ideal guide conditions, effectively reducing jamming and improving the reliability and service life of the slider body and antenna retraction mechanism.

It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] Please see Figure 1-4As shown in the embodiment of the present invention, a self-adjusting sliding cover mounting structure includes a vehicle body 1, guide rail adjustment components 2 are provided on both sides of the vehicle body 1, a sliding guide rail 3 is provided on the guide rail adjustment components 2, a slider body 4 is provided on the sliding guide rail 3, a floating mounting seat 5 is provided above the slider body 4, radial limiting components 6 are provided on both sides of the floating mounting seat 5 and the slider body 4, and vertical limiting components 7 are also provided around the floating mounting seat 5 and the slider body 4. The floating mounting seat 5 is connected to the sliding cover body 9 through a fixing component 8.

[0026] according to Figure 1 It should be noted that the sliding direction of the sliding cover body 9 is longitudinal, i.e., the Y direction, and no constraints are imposed here to facilitate the sliding of the sliding cover body 9 on the sliding guide rail 3; The radial limiting component 6 limits the lateral displacement of the slider body 4 by means of the lateral direction, i.e., the X direction. The vertical limiting component 7 is in the vertical direction, i.e., the Z direction, and is used to limit the vertical displacement of the slider body 4. The guide rail adjustment assembly 2 and the sliding guide rail 3 allow for initial fine-tuning of the guide rail on the vehicle body 1. The floating mounting seat 5 on the slider body 4 adaptively compensates for the guide rail position through the radial limiting assembly 6 and the vertical limiting assembly 7, ensuring that the movement of the slider body 4 on the sliding guide rail 3 is always smooth and automatically eliminating installation deviations. The radial limiting assembly 6 is used to allow the floating mounting seat 5 to float slightly in the lateral direction, thereby compensating for the lateral error of the guide rail. The vertical limiting assembly 7, which is set around the floating mounting seat 5 and the slider body 4, provides elastic support and limiting guidance in the vertical direction, allowing the floating mounting seat 5 to absorb the influence of local protrusions or height changes on the surface of the sliding guide rail 3, preventing the slider body 4 from jamming due to vertical jamming during operation. The sliding cover body 9 is stably installed on the floating mounting seat 5 through the fixing assembly 8, ensuring the overall rigidity and load-bearing capacity of the sliding cover body 9 while keeping the sliding cover body 9 in a state of force balance during sliding. This enables the sliding cover to adaptively adjust and operate smoothly under non-ideal guide rail conditions, effectively reducing jamming and improving the reliability and service life of the sliding cover and antenna retraction mechanism.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the radial limiting component 6 includes a mounting plate 61, which is mounted on the floating mounting seat 5. A limiting groove 62 is provided in the mounting plate 61, and a limiting shaft 63 is provided in the limiting groove 62. The limiting shaft 63 is located between the floating mounting seat 5 and the mounting plate 61. An elastic buffer 64 is sleeved on the outside of the limiting shaft 63. When the slider body 4 moves along the sliding guide rail 3 or is subjected to external force, the floating mounting seat 5 can float slightly in the lateral direction under the action of the radial limiting component 6. The elastic buffer 64 provides preload force, so that the floating mounting seat 5 always maintains a centered force state, while absorbing lateral impact and vibration, compensating for the lateral deviation of the guide rail and the vehicle body 1, and ensuring the smooth and stable operation of the sliding cover body 9.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, a preload screw 65 is also provided on one side of the mounting plate 61. The preload screw 65 abuts against the limiting shaft 63. When it is necessary to adjust the radial position of the floating mounting seat 5 or the force state of the limiting shaft 63, the compression amount of the elastic buffer 64 can be changed by rotating the preload screw 65, thereby adjusting the preload force of the floating mounting seat 5 in the horizontal direction so that it is always in the centered force state.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the vertical limiting component 7 includes a support component 71, which is disposed on the floating mounting base 5. An elastic support member 72 is sleeved below the support component 71 and is disposed between the floating mounting base 5 and the slider body 4. During operation, the support component 71 provides vertical guidance and load-bearing for the floating mounting base 5, controlling its vertical displacement. The elastic support component 72 is in a pre-compression state during installation, providing continuous upward elastic support for the floating mounting base 5. This allows it to float slightly up and down when there is unevenness in the sliding guide rail 3, thus automatically compensating for vertical installation errors. At the same time, when the sliding cover body 9 is subjected to vertical loads or running vibrations, the elastic support component 72 can absorb the impact and distribute the force evenly, preventing the floating mounting base 5 from rigidly jamming with the slider body 4 or from experiencing localized concentrated force. This ensures that the slider body 4 runs smoothly along the sliding guide rail 3. In specific implementation, the support component 71 can be fixed to the floating mounting base 5 using a support rod 711 structure. The elastic support component 72 is preferably a cylindrical spring 721, the lower end of which can cooperate with the slider body 4 through a guide structure to achieve a combination of elastic support and stable guidance, thereby improving the stability and reliability of the entire sliding cover installation structure in the vertical direction.

[0030] In one embodiment, see Figure 1 , Figure 2and Figure 3 As shown, the support assembly 71 includes a support rod 711, which is mounted on the floating mounting base 5. A limiting step 712 is provided on one side of the upper part of the support rod 711, and an elastic support member 72 is sleeved on the limiting step 712. During operation, the support rod 711 provides vertical guidance and positioning for the floating mounting base 5, while the limiting step 712 axially limits the elastic support member 72 to prevent it from shifting or dislodging under pressure. The elastic support member 72 is pre-compressed during installation, ensuring that the floating mounting base 5 receives continuous and uniform elastic support force in the vertical direction. When the slider body 4 moves along the sliding guide rail 3 or when there are local unevenness in the guide rail, the floating mounting base 5 can move slightly up and down under the action of the elastic support member 72, thereby automatically compensating for installation errors in the vertical direction.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the elastic support 72 includes a cylindrical spring 721. The upper side of the cylindrical spring 721 is fitted onto a limiting step 712, and a guide pin 722 is provided at the lower part of the cylindrical spring 721. The guide pin 722 is detachably connected to the slider body 4. During operation, the limiting step 712 provides upper positioning and axial limiting for the cylindrical spring 721, preventing the spring from shifting during compression or rebound. The guide pin 722 guides the lower end of the cylindrical spring 721, ensuring stable vertical movement during compression and extension, preventing tilting, bending, or jamming. The cylindrical spring 721 is in a pre-compressed state during installation, providing continuous upward elastic support to the floating mounting base 5. This allows it to float slightly up and down when there are local unevenness in the guide rail or errors in the mounting surface of the vehicle body 1, thus automatically compensating for vertical installation deviations.

[0032] In one embodiment, see Figure 1 , Figure 2 and Figure 4 As shown, the fixing component 8 includes a mounting plate 81 with several adjustment slots 82 and fastening bolts 83 installed in the adjustment slots 82. The mounting plate 81 is detachably connected to the floating mounting base 5 by the fastening bolts 83. During installation and debugging, the adjustment slots 82 provide movable space for the fastening bolts 83, allowing the mounting plate 81 to be finely adjusted relative to the floating mounting base 5 within a certain range, thereby achieving precise alignment between the sliding cover body 9 and the floating mounting base 5. After adjustment, the mounting plate 81 is reliably locked onto the floating mounting base 5 by tightening the fastening bolts 83, forming a stable rigid connection.

[0033] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the guide rail adjustment assembly 2 includes a guide rail adjustment plate 21, which is slidably connected to the top of the vehicle body 1. An adjustment screw 22 is fixedly connected to one side of the upper part of the guide rail adjustment plate 21. The adjustment screw 22 is rotatably connected to the vehicle body 1. By rotating the adjustment screw 22, the adjustment screw 22 only rotates on the vehicle body 1 without axial movement. Its fixed connection with the guide rail adjustment plate 21 causes the guide rail adjustment plate 21 to generate linear displacement on the vehicle body 1 along a preset sliding direction, thereby driving the sliding guide rail 3 installed on the guide rail adjustment plate 21 to move as a whole, realizing precise adjustment of the position of the sliding guide rail 3, and correcting the straightness and parallelism errors generated during the installation of the sliding guide rail 3.

[0034] In one embodiment, see Figure 1 and Figure 2 As shown, several reset springs 10 are also provided between the guide rail adjustment plate 21 and the vehicle body 1. The reset springs 10 can be symmetrically arranged on both sides or multiple positions of the guide rail adjustment plate 21 to ensure that the guide rail adjustment plate 21 is subjected to uniform force. The elastic coefficient of the reset springs 10 can be selected according to the weight of the guide rail and the adjustment stroke, so as to effectively improve the vibration resistance and position holding ability of the guide rail adjustment assembly 2 in long-term operation while ensuring the adjustment sensitivity.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, an inspection port 11 is provided on the top of the sliding cover body 9. The inspection port 11 is used for inspecting, maintaining, and replacing key components inside the sliding cover, such as the guide rail, slider body 4, floating mounting base 5, radial limiting assembly 6, and vertical limiting assembly 7. Structurally, the inspection port 11 is directly connected to the internal space of the sliding cover body 9, allowing maintenance personnel to operate on internal components without completely disassembling the sliding cover body 9, thereby reducing the impact of disassembly and assembly processes on the parallelism of the guide rail and installation accuracy.

[0036] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
