Description

Technical Field

[0001] The present invention relates to the technical field of sunshade curtains, and in particular to a sunshade curtain device, a vehicle and an operating method. Background Art

[0002] At present, there are two ways to open and close the sunshades in the cabs of cars and trucks: manual opening and closing and automatic opening and closing. Automatic opening and closing requires the addition of motors and electronic control systems, which are costly and difficult to repair and maintain. In order to reduce production and use costs, sunshades are mostly opened and closed manually.

[0003] Traditional manually opened and closed sunshades use the friction between the sunshade slider and the guide rail running groove to achieve a hovering function. Traditional manually opened and closed sunshades are difficult to fix in position after opening, and are prone to movement in driving scenarios such as sudden braking. In order to improve the position fixing ability of manually opened and closed sunshades when in use, manual opened and closed sunshades with locking structures are now available to improve the convenience of using manually opened and closed sunshades.

[0004] Existing manual opening and closing sunshades with locking structures require the operator to manually lock or unlock the locking structure when manually opening or closing the sunshade, which adds too many hand operation movements and is not in line with the traditional push-pull operation habits of manual sunshades. Especially when the sunshade operator is the driver, when manually operating the locking structure, the locking or unlocking action of the hand will distract the driver's attention too much, seriously affecting driving safety, and the sunshade requires manual assistance throughout the retraction process, which will also distract the driver's attention. Summary of the invention

[0005] In order to solve the technical problem that the existing manual opening and closing sunshade with a locking structure in the above-mentioned background technology adds too many hand operation movements, easily distracts the driver's attention, and seriously affects driving safety, the present invention provides a sunshade device, a vehicle and an operation method.

[0006] The technical solution of the present invention is as follows: The present invention provides a sunshade curtain device, including a curtain cloth, one side of the curtain cloth is fixedly connected to a rotating shaft assembly, and the other side of the curtain cloth is fixedly connected to a locking assembly, guide rails are arranged at both ends of the curtain cloth, and a limiting groove is arranged on the lower surface of one end of the guide rail away from the rotating shaft assembly, and the locking assembly includes a connecting bracket, both ends of the connecting bracket are fixedly connected to the limiting buckles and are slidably arranged in the corresponding guide rails, the limiting buckles are elastic parts, and a handle is connected to the lower surface of the connecting bracket at the center position, and a clamping part is fixedly arranged on the lower surface of the limiting buckle, and the clamping part is located on a side of the connecting bracket close to the rotating shaft assembly. When the curtain cloth needs to be rolled up, the operator only needs to pull the handle obliquely downward, and the handle drives the limiting buckles at both ends of the handle to be provided with the clamping part The rear side is tilted up through the connecting bracket, thereby realizing the separation of the clamping part and the corresponding limiting groove, and then releasing the lock of the curtain cloth, which is the same as the hand movement of the traditional manual sunshade curtain, without adding other redundant movements, not only can it achieve quick unlocking, but also will not distract too much attention, thereby ensuring driving safety.

[0007] Preferably, the upper surface and the lower surface of the limit buckle are always in contact with the upper and lower inner walls of the corresponding guide rail to avoid gaps, so that the two limit buckles can move synchronously without deviation, ensuring smooth winding of the curtain.

[0008] Preferably, a support block is provided inside the limiting buckle, and the support block is an elastic member, which is used to support the upper and lower parts of the limiting buckle to ensure that the upper and lower surfaces of the limiting buckle can always contact the upper and lower inner walls of the corresponding guide rail.

[0009] Preferably, the deformation capacity of the support block is stronger than that of the limiting buckle, which promotes the rebound of the limiting buckle and prevents the clamping part from automatically escaping from the limiting groove, and at the same time, avoids fatigue failure of the limiting buckle.

[0010] Preferably, a plug is fixedly provided on each guide rail, and the shaft assembly is rotatably arranged between the two plugs, so as to facilitate the installation of the shaft assembly and prevent the connecting bracket from falling out of the guide rail when the curtain is rolled back.

[0011] Preferably, the rotating shaft assembly includes a rotating shaft, which is a hollow tubular structure. Both ends of the rotating shaft are rotatably arranged on the plug through connecting pieces. A torsional energy storage unit is provided inside the rotating shaft. One end of the torsional energy storage unit is fixedly connected to a connecting piece, and the other end of the torsional energy storage unit is fixedly connected to the rotating shaft through a damper. The torsional energy storage unit can drive the rotating shaft to automatically rotate around the axis, thereby realizing automatic recovery of the curtain. The damper is used to ensure smooth recovery of the curtain.

[0012] Preferably, the torsional energy storage unit is a torsion spring, so as to store energy when the curtain is unfolded.

[0013] The invention provides a vehicle, which adopts a sunshade curtain device.

[0014] The present invention provides an operating method, which is specifically as follows: when the sunshade needs to be opened, the handle is manually pulled toward the front of the vehicle, and the limit buckles at both ends are driven to move along the corresponding guide rails through the connecting bracket. When the curtain is unfolded into place, the clamping parts at the bottom of the rear side of the two limit buckles are clamped into the corresponding limit grooves to achieve self-locking. The unfolding method of the curtain is the same as the manual unfolding method of the traditional sunshade, without increasing hand movements. While facilitating operation, the curtain is self-locking in place and movement of the curtain is avoided.

[0015] Preferably, when the sunshade needs to be closed, the operator pulls the handle diagonally downward, the handle generates torque and drives the limit buckles at both ends of it to tilt up with the rear side of the clamping part through the connecting bracket, the clamping part is separated from the corresponding limit groove, and the shaft rotates under the action of the torsional energy storage unit, and the curtain is automatically retracted. The operator only needs to pull the handle diagonally downward, which is the same as the hand movement of the traditional manual sunshade without adding other unnecessary movements. It can not only achieve quick unlocking, but also will not distract too much attention, thus ensuring driving safety. At the same time, the curtain has the ability to automatically rewind, without the need for manual assistance, which further reduces distraction.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are: 1. Guide rails are provided at both ends of the curtain, and a limiting groove is provided on the lower surface of one end of the guide rail away from the rotating shaft assembly. Both ends of the connecting bracket are fixedly connected to the limiting buckles and slidably arranged in the corresponding guide rails. A clamping part is fixedly provided on the lower surface of the limiting buckle, and the clamping part is located on the side of the connecting bracket close to the rotating shaft assembly. When the curtain needs to be rolled up, the operator only needs to pull the handle obliquely downward, and the handle drives the limiting buckles at both ends of the handle to tilt up with the rear side of the clamping part through the connecting bracket, thereby realizing the separation of the clamping part and the corresponding limiting groove, and then releasing the lock of the curtain. It is the same as the hand movement of the traditional manual sunshade, without adding other redundant movements. It can not only realize quick unlocking, but also will not distract too much attention, thereby ensuring driving safety.

[0017] 2. A support block is provided inside the limit buckle to ensure that the upper and lower surfaces of the limit buckle can always contact the upper and lower inner walls of the corresponding guide rail, so that the two limit buckles can move synchronously without deviation, ensuring smooth curtain winding, while promoting the rebound of the limit buckle and preventing the clamping part from automatically escaping from the limit groove, and avoiding fatigue failure of the limit buckle.

[0018] 3. The rotating shaft assembly stores energy through the torsion energy storage unit, so that the curtain cloth has the ability to automatically rewind without manual assistance. Combined with the use of the locking assembly, it effectively reduces distraction and ensures driving safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0022] Example 1 In a typical embodiment of the present invention, a sunshade device is provided, such as Figure 1 , Figure 2 As shown, the sunshade curtain device includes: a curtain 1, two guide rails, a rotating shaft assembly and a locking assembly. One side of the curtain 1 is fixedly connected to the rotating shaft assembly by bonding. The curtain 1 can be rolled up onto the rotating shaft assembly following the rotation of the rotating shaft assembly to play a role in sunshade or insect prevention when the sunroof is opened. The other side of the curtain 1 is fixedly connected to the locking assembly by bonding and can move with the locking assembly. Two guide rails are set at both ends of the curtain 1, and the two ends of the curtain 1 are placed in adjacent guide rails. The two ends of the locking assembly are slidably set in the adjacent guide rails. Through the cooperation of the locking assembly and the guide rails, the position of the curtain 1 after opening is locked to prevent the curtain 1 from moving.

[0023] In this embodiment, the guide rail is divided into a first guide rail 2 and a second guide rail 3. The first guide rail 2 and the second guide rail 3 are relatively arranged at two ends of the curtain 1 to play a guiding and limiting role.

[0024] like Figure 3 As shown, the rotating shaft assembly includes a first plug 6, a second plug 7, a rotating shaft 8, a damper 9, a connecting piece 10 and a torsional energy storage unit. The torsional energy storage unit is a torsion spring 11. The rotating shaft 8 is a hollow tubular structure. The two ends of the rotating shaft 8 are rotatably connected with the first plug 6 and the second plug 7 respectively. Specifically, the first plug 6 is fixedly arranged on the first guide rail 2 by bolt installation, and the second plug 7 is fixedly arranged on the second guide rail 3 by bolt installation. The two ends of the rotating shaft 8 are rotatably connected with a connecting piece 10 respectively, and are rotatably connected with the adjacent first plug 6 and second plug 7 through the connecting piece 10. The connecting piece 10 is used to limit the axial position of the rotating shaft 8.

[0025] Among them, the two connecting parts 10 are rotationally connected to the rotating shaft 8, and the connecting part 10 is fixedly connected to the corresponding first plug 6 and second plug 7. The torsion spring 11 is arranged inside the rotating shaft 8, and one end of the torsion spring 11 is fixedly connected to the connecting part 10 on the adjacent first plug 6, and the other end of the torsion spring 11 is fixedly connected to the damper 9. The damper 9 is placed in the rotating shaft 8, and the damper is fixedly connected to the inner wall of one end of the rotating shaft 8 close to the second plug 7 by interference fit or the like, so that the torsion spring 11 can be twisted when the rotating shaft 8 rotates. After the curtain 1 is released, the torsion spring 11 drives the damper 9 to rotate, and then drives the rotating shaft 8 to rotate through the damper 9, so as to realize the automatic winding of the curtain 1 of the rotating shaft 8. During this period, the damper 9 provides resistance for the torsion spring 11 to release mechanical energy, so as to ensure smooth winding of the curtain 1 and reduce vibration.

[0026] like Figure 4 As shown, the locking assembly includes a first limit buckle 4, a second limit buckle 5, a handle 12 and a connecting bracket 14. The first limit buckle 4 is fixedly arranged at one end of the connecting bracket 14, and the second limit buckle 5 is fixedly arranged at the other end of the connecting bracket 14. Both ends of the connecting bracket 14 are slidably arranged in the first guide rail 2 and the second guide rail 3 located at both ends thereof. The first limit buckle 4 and the second limit buckle 5 are both elastic parts. Specifically, the first limit buckle 4 is slidably arranged in the first guide rail 2, and the second limit buckle 5 is slidably arranged in the second guide rail 3. The lower surface of the center position of the connecting bracket 14 is fixedly connected with the handle 12 by a bolt 13, so as to drive the connecting bracket 14 to slide along the length direction of the first guide rail 2 and the second guide rail 3 through the handle 12.

[0027] like Figure 5 As shown, the lower surface of one end of the first guide rail 2 and the second guide rail 3 away from the rotating shaft assembly is provided with a limiting groove 16, and the limiting groove 16 penetrates the lower surface of the corresponding guide rail, and the lower surface of the first limiting buckle 4 and the second limiting opening 5 are fixedly provided with a clamping portion 17, so that the clamping portion 17 cooperates with the corresponding limiting groove 16 (as shown in FIG. Figure 6 and Figure 7 As shown), the position of the curtain 1 after opening is locked and fixed, so as to limit the position of the curtain 1 and prevent it from moving due to sudden braking or other reasons.

[0028] The clamping portion 17 is located at the rear of the connecting bracket 14, that is, the clamping portion 17 is located at the side of the connecting bracket 14 close to the rotating shaft assembly (which can also be understood as the rear of the opening and moving path of the curtain 1), so that when the curtain 1 needs to be rolled up, the operator only needs to pull the handle 12 located in front of his head obliquely downward, and the handle 12 drives the first limit buckle 4 and the second limit buckle 5 at both ends thereof through the connecting bracket 14. The rear side of the clamping portion 17 is tilted (such as Figure 8 , Fig. 9 , Fig.10As shown), the clamping portion 17 is separated from the corresponding limiting groove 16, thereby releasing the lock on the curtain 1.

[0029] The traditional manual sunshade retraction action is that the operator pulls the sunshade diagonally downward and backward. In this embodiment, the operation of the handle 12 is also to pull it diagonally downward, which is the same as the hand movement of the traditional manual sunshade without adding other unnecessary movements. It can not only achieve quick unlocking, but also will not distract too much attention, thereby ensuring driving safety.

[0030] In order to ensure that the first limit buckle 4 and the second limit buckle 5 can move synchronously and avoid jamming when the curtain 1 is recovered, the present embodiment further provides a support block 15 inside the first limit buckle 4 and the second limit buckle 5. The support block 15 is an elastic member, and the support block 15 is used to support the upper and lower parts of the corresponding limit buckles to ensure that the first limit buckle 4 and the second limit buckle 5 can always fill the guide rail, that is, the upper and lower surfaces of the first limit buckle 4 and the second limit buckle 5 are always in contact with the upper and lower inner walls of the corresponding guide rail to avoid gaps, so that the first limit buckle 4 and the second limit buckle 5 can move synchronously without deviation, thereby ensuring smooth winding of the curtain 1.

[0031] The support block 15 is also an elastomer, and the deformation ability of the support block 15 is stronger than that of the first limit buckle 4 and the second limit buckle 5. In this embodiment, the support block 15 is made of Epdm material, and the first limit buckle 4 and the second limit buckle 5 are made of pom material, so that the first limit buckle 4 and the second limit buckle 5 are supported by the support block 15, which promotes the rebound of the limit buckle and prevents the clamping part 17 from automatically escaping from the limit groove 16, and at the same time, avoids fatigue failure of the first limit buckle 4 and the second limit buckle 5.

[0032] The specific working principle is: When the sunshade needs to be opened, the handle 12 is manually pulled toward the front of the vehicle, and the first limit buckle 4 and the second limit buckle 5 at both ends are driven to move along the corresponding first guide rail 2 and the second guide rail 3 toward the front of the vehicle through the connecting bracket 14. When the curtain 1 is fully opened, the clamping parts 17 at the bottom of the rear side of the first limit buckle 4 and the second limit buckle 5 are clamped into the corresponding limit groove 16, so that the sunshade is opened and self-locked. While the curtain 1 is pulled to unfold, the rotating shaft 8 rotates around the axis and stores potential energy through the torsion spring 11. When the sunshade needs to be closed, the operator pulls the handle 12 located in front of his head diagonally downward, and the handle 12 generates a torque and drives the first limit buckle 4 and the second limit buckle 5 at both ends thereof to tilt up the rear side of the clamping portion 17 through the connecting bracket 14, thereby realizing the separation of the clamping portion 17 and the corresponding limit groove 16, thereby releasing the lock on the curtain 1, and the shaft 8 rotates under the action of the torsion spring 11, thereby realizing the automatic retraction of the curtain 1.

[0033] Example 2 In another typical embodiment of the present invention, Fig.11 As shown, a vehicle is proposed, which adopts the sunshade device in Example 1, and the sunshade device is installed at the skylight of the vehicle cab. Example 3 In another typical embodiment of the present invention, a method for operating a sunshade device is provided, which is specifically as follows: When the sunshade needs to be opened, the handle 12 is manually pulled toward the front of the vehicle, and the first limit buckle 4 and the second limit buckle 5 at both ends are driven to move along the corresponding first guide rail 2 and the second guide rail 3 toward the front of the vehicle through the connecting bracket 14. When the curtain 1 is fully opened, the clamping parts 17 at the bottom of the rear side of the first limit buckle 4 and the second limit buckle 5 are clamped into the corresponding limit groove 16, so that the sunshade is opened and self-locked. While the curtain 1 is pulled to unfold, the rotating shaft 8 rotates around the axis and stores potential energy through the torsion spring 11. When the sunshade needs to be closed, the operator pulls the handle 12 located in front of his head diagonally downward, and the handle 12 generates a torque and drives the first limit buckle 4 and the second limit buckle 5 at both ends thereof to tilt up the rear side of the clamping portion 17 through the connecting bracket 14, thereby realizing the separation of the clamping portion 17 and the corresponding limit groove 16, thereby releasing the lock on the curtain 1, and the shaft 8 rotates under the action of the torsion spring 11, thereby realizing the automatic retraction of the curtain 1, and ensuring the smooth winding of the curtain 1 under the action of the damper 9.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
