Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an integrated, thin, dual-section automotive sunshade structure. Background Technology

[0002] Car sunshades are common interior components in modern cars. They are installed in the sunroof or rear window to block sunlight and heat from the driver and passengers when exposed to strong sunlight, thereby improving the comfort of the ride.

[0003] With the development of automotive technology, especially the widespread adoption of electric sunroofs and intelligent interiors, the application of electric sunshades is becoming increasingly common. These sunshades typically integrate a motor, transmission mechanism, and curtain fabric, installed as a "one-piece" assembly on the roof lining or fixed panel to achieve automated and convenient sunshade control.

[0004] However, this highly integrated one-piece design also brings a significant drawback. Because the sunshade assembly is usually designed to be permanently or semi-permanently fixed to the vehicle body structure, its installation and fixing methods are complex, often requiring multiple bolts or hidden clips to connect it to the roof mounting plate.

[0005] If the motor, transmission components, or curtain fabric of the sunshade malfunctions or is damaged, requiring repair or replacement, repair personnel must extensively disassemble the headliner and surrounding interior panels to access the fixing points of the sunshade assembly. This process is not only time-consuming and labor-intensive, but also highly susceptible to secondary damage to the interior panels during disassembly and reassembly, leading to high repair costs and significant inconvenience for car owners.

[0006] Therefore, this utility model proposes an integrated, thin, dual-section automotive sunshade structure to address the shortcomings of existing technologies. Summary of the Invention

[0007] In view of the problems of complex assembly fixing methods, difficulty in disassembly after damage, and cumbersome and time-consuming maintenance and replacement processes in the existing integrated thin dual-section automotive sunshade structure, this utility model aims to provide an integrated thin dual-section automotive sunshade structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides an integrated, thin, two-section automotive sunshade structure, comprising: a vehicle body, a support assembly, the support assembly being fixedly connected to the top of the vehicle body, the support assembly including a fixing plate fixedly connected to the top of the vehicle body, and a housing installed on the fixing plate, an unfolding mechanism disposed within the housing, the unfolding mechanism including a motor and a sunshade cloth, the motor being used to drive the sunshade cloth to unfold, and a disassembly mechanism being used to realize a detachable connection between the housing and the fixing plate.

[0009] The disassembly mechanism includes a connecting post fixedly connected to the bottom of the outer casing and a fixing post fixedly connected to the top of the fixing plate, wherein the connecting post has a groove.

[0010] Furthermore, the disassembly mechanism also includes a hollow column fixedly connected to the top of the fixed column, and a locking ball disposed in a hole opened in the hollow column.

[0011] The disassembly mechanism further includes a spring fixedly connected to the top of the fixed post, and a pressing post, the pressing post having a locking block fixedly connected inside.

[0012] The locking block presses against the spring and the locking ball, causing the locking ball to engage with the groove of the connecting post under the action of the spring to achieve locking; the pressing post is used to push the locking block to compress the spring when it is pressed, thereby releasing the engagement between the locking ball and the groove.

[0013] Preferably, the unfolding mechanism further includes a gear installed inside the housing and a rack disposed inside the housing and engaged with the gear. The gear is connected to the motor for transmission, and the rotational motion of the motor is converted into the linear motion of the rack through the meshing of the gear and the rack.

[0014] Preferably, based on the above-mentioned unfolding mechanism, the unfolding mechanism further includes a rotating column fixedly connected to one side of the gear, the main body of the sunshade cloth is wrapped around the outside of the rotating column, and the rotating column rotates synchronously with the gear to wind or release the sunshade cloth.

[0015] Preferably, a groove is provided on one side of the rack, and the unfolding mechanism further includes a slider that is slidably connected in the groove of the rack. The slider is fixedly connected to one side of the sunshade cloth, and the slider moves linearly synchronously with the rack, thereby causing the sunshade cloth to unfold or retract.

[0016] Preferably, in order to achieve a compact layout, the motor is fixedly connected to one side of the housing to provide a power source for the unfolding mechanism.

[0017] Preferably, the support component, the unfolding mechanism, and the disassembly mechanism together constitute a sunshade assembly that can be disassembled as a whole. The assembly is connected to the vehicle body as a complete module, which facilitates overall installation or disassembly.

[0018] Preferably, the fixed post and the hollow post together define a chamber for accommodating the spring and the locking block, the chamber providing the necessary internal space and guidance for the compression and reset of the spring and the up-and-down movement of the locking block.

[0019] Preferably, the locking block has a tapered surface or an inclined surface, which is used to convert the axial pressing force of the pressing column into a radial thrust on the locking ball when the pressing column is pressed down, thereby pushing the locking ball to overcome the elastic force of the spring and retract radially, thereby achieving unlocking.

[0020] This utility model has the following beneficial effects: 1. This utility model, by setting up a disassembly mechanism consisting of a connecting post, a fixing post, a locking ball, a spring, and a pressing post, allows the locking ball to be engaged and disengaged from the groove of the connecting post by pressing the pressing post. This solves the problems of difficulty in disassembling, complex repair and replacement, and high cost of automotive sunshade assemblies after damage in the prior art. It achieves the effects of simple structure, quick tool-free disassembly and assembly, and great convenience for later maintenance and replacement.

[0021] 2. This utility model, by setting up an unfolding mechanism composed of a motor, gears, racks and sliders, uses the motor to drive the gears, which in turn drive the racks and sliders to achieve linear motion, solves the problems of inconvenient manual operation or unstable transmission of some sunshade curtains, achieves automated sunshade, improves ease of use, and has a stable and reliable transmission process and smooth unfolding of the sunshade cloth.

[0022] 3. This utility model integrates the unfolding mechanism and the disassembly mechanism into the outer shell and the fixed plate of the support component, and uses a spring to drive the locking ball to achieve a stable lock. This solves the problems of complicated installation of the split structure and easy loosening or abnormal noise of the detachable structure under vehicle vibration. It achieves the effect of compact overall structure, high integration, simple installation, and stable and reliable connection with strong vibration resistance. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Reference Figures 1 to 5 The integrated, thin, dual-section automotive sunshade structure includes a support assembly 3 fixed to the vehicle body 1, and an unfolding mechanism 2 disposed inside the support assembly 3. The support assembly 3 includes a fixing plate 31 fixedly connected to the top of the vehicle body 1, and a housing 32 mounted on the fixing plate 31. The housing 32 is used to house the unfolding mechanism 2, which includes a motor 21 and a sunshade cloth 26 for achieving the sunshade function. A disassembly mechanism 4 is used to achieve a detachable connection between the housing 32 and the fixing plate 31. Reference Figures 2 to 5 The disassembly mechanism 4 includes a connecting post 41 fixedly connected to the bottom of the outer casing 32 and a fixing post 42 fixedly connected to the top of the fixing plate 31. The connecting post 41 has a groove. The disassembly mechanism 4 also includes a hollow post 46 fixedly connected to the top of the fixing post 42 and a locking ball 47 disposed in a hole in the hollow post 46. The disassembly mechanism 4 further includes a spring 43 fixedly connected to the top of the fixing post 42 and a pressing post 44. A locking block 45 is fixedly connected inside the pressing post 44. In the installed state, the locking block 45 presses the spring 43 and the locking ball 47, so that the locking ball 47 is engaged in the groove of the connecting post 41 under the action of the spring 43, thereby achieving locking. When disassembly is required, the pressing post 44 is pressed, and the pressing post 44 pushes the locking block 45 to compress the spring 43. At this time, the locking ball 47 disengages from the groove and the locking state is released. The fixed post 42 and the hollow post 46 together define a chamber for accommodating the spring 43 and the locking block 45. The locking block 45 has a tapered or inclined surface for pushing the locking ball 47 to overcome the elastic force of the spring 43 and retract radially when the pressing post 44 is pressed down. The support assembly 3, the unfolding mechanism 2 and the disassembly mechanism 4 together constitute a sunshade assembly that can be disassembled as a whole. The unfolding mechanism 2 also includes a rack 24 disposed inside the housing 32, and a specific sliding connection relationship is formed between the slider 25 and the rack 24.

[0027] Reference Figures 2 to 4 The rack 24 is located inside the outer casing 32, and a groove is provided on one side of the rack 24. The slider 25 is slidably connected to the groove of the rack 24. The slider 25 is fixedly connected to one side of the sunshade cloth 26. To drive the rack 24, the unfolding mechanism 2 also includes a motor 21 and a gear 22. The motor 21 is fixedly connected to one side of the outer casing 32, and the gear 22 is installed inside the outer casing 32 and is connected to the motor 21 for transmission. The rack 24 is engaged with the gear 22. The unfolding mechanism 2 includes a rotating column 23 fixedly connected to one side of the gear 22. The main body of the sunshade cloth 26 is wrapped around the rotating column 23. The structure of the gear 22 and rack 24 transmission and slider 25, driven by the motor 21 to rotate the gear 22, drives the rack 24 to move laterally. The rack 24 then drives the slider 25 and the sunshade cloth 26 to move laterally synchronously, ensuring the smoothness and accuracy of unfolding and retracting the sunshade cloth 26.

[0028] In a preferred embodiment, the motor 21 is fixedly connected to one side of the housing 32. The support component 3, the unfolding mechanism 2 and the disassembly mechanism 4 together constitute a sunshade assembly that can be disassembled as a whole. This integrated design facilitates quick installation and subsequent maintenance and replacement. The fixing column 42 and the hollow column 46 together define a chamber for accommodating the spring 43 and the locking block 45, providing a stable internal space for the pressing and resetting of the disassembly mechanism 4.

[0029] As another preferred embodiment, the locking block 45 has a tapered or inclined surface, which is used to push the locking ball 47 against the elastic force of the spring 43 when the pressing post 44 is pressed down, so that the locking ball 47 retracts radially and disengages from the groove of the connecting post 41.

[0030] The implementation principle of this application embodiment is as follows: When the vehicle needs sunshade, the unfolding mechanism 2 can extend the sunshade cloth 26 for sunshade. The motor 21 is fixedly connected to one side of the housing 32 to provide power. The gear 22 is installed inside the housing 32 to convert the force of the motor 21 into rotational motion. The rotating column 23 is fixedly connected to one side of the gear 22. The rack 24 is set inside the housing 32 and is engaged with the gear 22. When the gear 22 rotates, the rack 24 moves laterally. A groove is opened on one side of the rack 24. The slider 25 is slidably connected in the groove. The sunshade cloth 26 is wrapped around the outside of the rotating column 23. The slider 25 is fixedly connected to one side of the sunshade cloth 26. When the slider 25 moves outward, it will drive the sunshade cloth 26 to move, thereby blocking the sunlight. The support component 3 connects the unfolding mechanism 2 to the vehicle body 1 to ensure the stability of the structure.

[0031] When the unfolding mechanism 2 is damaged or not in use, a disassembly mechanism 4 can be provided for disassembly. The connecting column 41 is fixedly connected to the bottom of the outer shell 32, the fixing plate 31 is fixedly connected to the top of the vehicle body 1, the fixing column 42 is fixedly connected to the top of the fixing plate 31, the spring 43 is fixedly connected to the top of the fixing column 42, the locking block 45 is fixedly connected to the inside of the pressing column 44, and presses the spring 43 and the locking ball 47. The hollow column 46 is fixedly connected to the top of the fixing column 42, and the locking ball 47 is set in the hole opened in the hollow column 46, which cooperates with the groove opened in the connecting column 41 to lock the entire structure. When the unfolding mechanism 2 needs to be repaired or replaced, the pressing column 44 is pressed, the locking block 45 is pushed to compress the spring 43, the locking ball 47 is disengaged from the groove of the connecting column 41, and the locking state is released. The entire unfolding mechanism 2 can be easily removed from the fixing column 42. During installation, the connecting column 41 and the fixing column 42 are aligned, and the locking ball 47 automatically locks into the groove under the action of the spring 43 to complete the fixation.

[0032] 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.
