Description

Technical Field

[0001] The present application relates to the technical field of vehicle blinds, and in particular to a locking block, a locking mechanism, a blind assembly and a vehicle. Background Art

[0002] The blinds are generally used in the trunk of a car to effectively protect the privacy and safety of personal belongings. The blinds currently used are usually made by winding the retracted end of the blind around a retractable reel, and then leading out a telescopic end to connect with a pull rod, and by pulling the pull rod, the locking block body on the pull rod is driven to slide in the guide rail, and finally when the blind is unfolded, the locking block body is moved to the locking hook on the guide rail to lock the locking block body. When unlocking, it is necessary to first pull the locking block body to disengage it from the locking hook, and then slide the locking block up or down so that the locking block can be retracted along the guide rail using the recovery force of the blind. This locking method is complicated to operate when unlocking, and it is necessary to continue to move the locking block to a position staggered with the locking hook after the locking block body is unhooked in order to successfully retract the blind, which will bring inconvenience to the operator and affect the user experience.

DETAILED DESCRIPTION

[0052] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0054] The present embodiment provides a locking block, a locking mechanism, a curtain assembly and a vehicle. The locking surface on the locking block body can be engaged with the lock hook after the curtain is unfolded into place, wherein the first direction refers to the direction of the pulling force applied by the curtain to the locking block body. When the locking surface is engaged with the lock hook, the pulling force applied by the curtain to the locking block body can ensure the stability of the engagement between the locking surface and the lock hook. When unlocking and unhooking is required, only pressure needs to be applied to the pressure-bearing portion. At this time, the pressure-bearing portion can drive the locking block body to rotate around the support portion as the center, and the locking surface and the lock hook slide relative to each other until the locking surface is completely separated from the lock hook. At this time, the curtain can pull the locking block body back in the direction away from the lock hook through the connecting portion, and the locking block body slides from the lock hook through the sliding surface until the sliding surface is separated from the lock hook, and the unlocking is completely completed at this time. The entire unlocking action only needs to apply pressure to the pressure-bearing portion to make the locking surface tilt up, and the locking block body rotates with the support portion as the fulcrum to complete the unlocking and unhooking. The unlocking operation is simpler and more convenient, which can significantly improve the operator's experience. The following is a detailed description of it through specific embodiments:

[0055] Reference Figures 1 to 14As shown, a locking block provided in this embodiment includes a locking block body 1. Along the first direction, one end of the locking block body 1 is provided with a locking surface 15 for clamping with the side of the locking hook 2, and a side of the locking block body 1 adjacent to the locking surface 15 is formed with a sliding surface 18 for slidingly cooperating with the top of the locking hook 2. A pressure-bearing portion 16 is provided on the side of the locking block body 1 opposite to the locking surface 15, and a supporting portion 14 for supporting on the vehicle body is provided on the sliding surface 18. Along the first direction, the locking surface 15, the supporting portion 14 and the pressure-bearing portion 16 are arranged in sequence at intervals; a connecting portion 17 for connecting the covering curtain 51 is also provided on the locking block body 1; it should be noted that the first direction refers to the direction of the pulling force provided by the covering curtain 51 to the connecting portion 17.

[0056] The locking block provided in this embodiment has a locking surface 15 on the locking block body 1 that can be engaged with the locking hook 2 after the covering curtain 51 is unfolded in place. When the locking surface 15 is engaged with the locking hook 2, the tension applied to the locking block body 1 by the covering curtain 51 can ensure the stability of the engagement between the locking surface 15 and the locking hook 2. When unlocking and unhooking is required, it is only necessary to apply pressure to the pressure-bearing portion 16. At this time, the pressure-bearing portion 16 can drive the locking block body 1 to rotate around the supporting portion 14, and the locking surface 15 and the locking hook 2 slide relative to each other until the lock is engaged. The stop surface 15 is completely separated from the lock hook 2. At this time, the covering curtain 51 can pull the lock block body 1 back in the direction away from the lock hook 2 through the connecting portion 17. The lock block body 1 slides from the lock hook 2 through the sliding surface 18 until the sliding surface 18 is separated from the lock hook 2. At this time, the unlocking is completely completed; the entire unlocking action only needs to apply pressure to the pressure-bearing portion 16 to make the locking surface 15 tilt up. The lock block body 1 rotates with the support portion 14 as the fulcrum and completes the unlocking and unhooking. The unlocking operation is simpler and more convenient, which can significantly improve the operator's experience.

[0057] In some embodiments, the support portion 14 is located at the end of the sliding surface 18 away from the locking surface 15 in the first direction; when the pressure-bearing portion 16 is subjected to pressure, it will use the support portion 14 as the rotation center and the sliding surface 18 as the rotation axis to pry the locking surface 15 and the lock hook 2 to slide relative to each other until the locking surface 15 is separated from the lock hook 2.

[0058] In some embodiments, the pressure-receiving portion 16 extends a first set distance along the first direction toward a side away from the locking surface 15; such a setting can increase the length of the power arm, making it easier to apply pressure to the pressure-receiving portion 16, so that the operator can pry the locking surface 15 out of the lock hook 2 while applying less pressure to the pressure-receiving portion 16.

[0059] In a further embodiment, a trigger plate 54 is provided on the pressure-receiving portion 16, a first end of the trigger plate 54 is connected to the pressure-receiving portion 16, and the other end extends a second set distance along the first direction toward a side away from the locking surface 15; by setting the trigger plate 54, the length of the power arm can be further increased, and it will be more labor-saving when applying pressure to the pressure-receiving portion 16, so that the operator can pry the locking surface 15 out of the lock hook 2 when applying less pressure to the pressure-receiving portion 16.

[0060] Continue to refer to Fig.10 and Fig.13 As shown, the locking block also includes a buffer pad 11, which is staggered with the locking surface 15 in the second direction, and the second direction is perpendicular to the first direction to avoid the lock hook 2, and the buffer pad 11 is protruded from the locking surface 15 toward the side away from the pressure-bearing portion 16; it should be understood that when the covering curtain 51 is retracted toward the roller 52, the buffer pad 11 can be used to form a buffer between the locking block body 1 and the roller shell 55, and no hard collision will occur, thereby significantly improving the service life of the locking block body 1, the roller shell 55 and other structures hard-connected to the two.

[0061] Continue to refer to Fig.10 , Fig.11 , Fig.13 and Fig.14 As shown, the locking block also includes a plug-in assembly, and the locking block body 1 is plugged and matched with the reel shell 55 in a first direction through the plug-in assembly; through the setting of the plug-in assembly, when the covering curtain 51 pulls the locking block body 1 back to the position of the reel shell 55, the locking block body 1 and the reel shell 55 can be plugged and matched, thereby ensuring the stability of the locking block body 1 when the covering curtain 51 is retracted, and avoiding the vibration generated during the driving of the vehicle from causing the locking block body 1 and the reel shell 55 to collide with each other.

[0062] In some embodiments, the plug-in assembly includes an insertion section 12 disposed on one of the lock block body 1 and the reel shell 55, and a housing snap-in groove 551 disposed on the other, and the insertion section 12 is plugged and matched with the housing snap-in groove 551 along the first direction. Fig.10 and Fig.11 As shown, the insertion section 12 can be set on the lock block body 1, and the shell snap-in groove 551 can be set on the reel shell 55; wherein, the insertion section 12 and the shell snap-in groove 551 both extend a third set distance along the first direction, thereby ensuring that the insertion section 12 and the shell snap-in groove 551 can form a stable support perpendicular to the first direction after being plugged in and matched.

[0063] In a further embodiment, a plurality of support ribs 13 extending along a first direction are provided on the insertion section 12 or the shell snap-in groove 551, and the plurality of support ribs 13 are arranged between the insertion section 12 and the shell snap-in groove 551; it should be understood that the plurality of support ribs 13 are evenly arranged on the outer surface of the insertion section 12 along the circumference of the insertion section 12, or the plurality of support ribs 13 are evenly arranged on the inner surface of the shell snap-in groove 551 along the circumference of the shell snap-in groove 551, so that when the insertion section 12 and the shell snap-in groove 551 are inserted, the support ribs 13 can be utilized to make the two slide together and support them at the same time. The provision of the support ribs 13 can reduce the contact area between the two, thereby reducing the friction when the two are slidably plugged in.

[0064] On the second aspect, a locking mechanism provided in this embodiment includes a locking block as above, and also includes a locking hook 2 and a locking assembly 4. The locking hook 2 is snap-fitted with the locking surface 15 on the locking block. The locking assembly 4 includes a mounting shell 41 and a first elastic member 421. The mounting shell 41 is mounted on the vehicle body. The locking hook 2 is connected to the mounting shell 41 through the first elastic member 421. The first elastic member 421 provides an elastic force perpendicular to the first direction. It should be understood that the mounting shell 41 can be a part of the vehicle body or a base structure integrated on the guide rail 3, as long as it can provide an installation position for the locking hook 2 and the first elastic member 421 so that the locking hook 2 can move in a direction perpendicular to the first direction.

[0065] The locking mechanism provided in this embodiment, through the arrangement of the first elastic member 421, allows the lock hook 2 to move in a direction perpendicular to the first direction, and can use the sliding surface 18 to press the lock hook 2 down in a direction perpendicular to the first direction when the lock block body 1 contacts the lock hook 2, so as to achieve buffering. When the lock block body 1 moves into place, the elastic force of the first elastic member 421 can be used to restore the lock hook 2 to its original position, and then engage with the locking surface 15 of the lock block body 1, so as to achieve stable engagement and significantly reduce the collision force between the lock block body 1 and the lock hook 2; similarly, when unlocking, when the locking surface 15 of the lock block body 1 is tilted, as long as the lock block body 1 uses the cover curtain The recovery force of 51 forms a downward pressing trend on the lock hook 2, and the sliding surface 18 can be used to press the lock hook 2 downward until the locking surface 15 of the lock block body 1 is separated from the lock hook 2. The sliding surface 18 of the lock block body 1 can still continue to press the lock hook 2 downward, and the sliding surface 18 will slide on the top of the lock hook 2 until the two are completely separated. The setting of the first elastic member 421 can also make it easier to unlock the lock block body 1 and the lock hook 2. At the same time, the elastic collision between the lock block body 1 and the lock hook 2 can be achieved during unlocking, thereby reducing the damage to the lock block body 1 and the lock hook 2, increasing the service life of the entire locking mechanism, and reducing the difficulty of unlocking the lock block body 1 and the lock hook 2.

[0066] Continue to refer to Figures 1 to 5As shown, the lock hook 2 is provided with a supporting portion 21 extending along the first direction and a locking portion 25 perpendicular to the first direction. When the locking portion 25 is engaged with the locking surface 15, the supporting portion 21 is slidably engaged with the sliding surface 18; it should be understood that the supporting portion 21 can sink together with the lock hook 2 in the direction away from the avoidance groove 31, further reducing the difficulty of the lock block body 1 being separated from the lock hook 2, and when the locking surface 15 is engaged with the locking portion 25, the supporting portion 21 can be used to support the sliding surface 18 to improve the stability of the lock block body 1; wherein, the lock hook 2 can be integrally formed with the supporting portion 21, and can also be fixedly connected to the supporting portion 21 by bonding, welding, etc.

[0067] Continue to refer to Figures 2 to 5 As shown, the first end of the supporting portion 21 along the first direction is connected to the locking portion 25, and the second end is rotatably connected to the mounting shell 41 through the rotating shaft 22, and the axis of the rotating shaft 22 is perpendicularly arranged to the elastic force direction of the first elastic member 421, so as to realize the swinging of the lock hook 2 along a direction perpendicular to the first direction; it should be understood that the elastic force direction of the first elastic member 421 and the first direction are both located in the same plane, and the axis of the rotating shaft 22 is perpendicular to the plane, so that when the lock block body 1 squeezes the lock hook 2, the lock hook 2 can utilize the supporting portion 21 to swing around the rotating shaft 22; wherein, through the setting of the rotating shaft 22, the activity stability of the entire supporting portion 21 and the lock hook 2 can be improved, so that the two can swing along the set route when pressed down by the lock block body 1, thereby reducing the failure rate of the locking mechanism and avoiding the situation where the lock block body 1 and the lock hook 2 are stuck.

[0068] In some embodiments, a sliding groove 411 extending in an axial direction perpendicular to the rotating shaft 22 is provided on the mounting shell 41, and the rotating shaft 22 is slidably arranged in the sliding groove 411; through the setting of the sliding groove 411, the entire lock hook 2 and the supporting part 21 can move more flexibly when pressed down by the locking block body 1, thereby increasing the descending range of the entire lock hook 2 and the supporting part 21, while avoiding the occurrence of dead points, and preventing the lock hook 2 and the supporting part 21 from being stuck by the mounting shell 41 when moving; it should be understood that the rotating shaft 22 can rotate along its own axis in the sliding groove 411.

[0069] Continue to refer to Figures 5 to 7As shown, the rotating shaft 22 is slidably arranged between the first end and the second end of the sliding groove 411, and the first end and the second end of the sliding groove 411 have a height difference in the direction of the elastic force of the first elastic member 421; it should be understood that the sliding groove 411 can be a straight groove, an oblique groove or an arc groove; as long as it can be ensured that the rotating shaft 22 can slide smoothly between the two ends of the sliding groove 411; the first end and the second end of the sliding groove 411 are arranged to have a height difference in the direction of the elastic force of the first elastic member 421, so that when the lock hook 2 is pressed down by the lock block body 1, the lock hook 2 and the second end of the supporting portion 21 can be synchronously moved in the direction away from the avoidance groove 31, that is, the overall downward movement is achieved, and then it is easier to achieve unlocking and decoupling between the lock hook 2 and the lock block body 1; Figure 5 The middle dotted area represents the positions and postures of the locking block body 1 , the locking hook 2 , the supporting portion 21 , the first elastic member 421 and the second elastic member 422 when the locking block body 1 is squeezing the locking hook 2 .

[0070] Continue to refer to Figure 4 As shown, one end of the rotating shaft 22 along its axial direction is connected to the supporting portion 21, and the other end is plugged into the sliding groove 411; that is, the supporting portion 21 is only connected to one axial end of the rotating shaft 22, so that the other axial end of the rotating shaft 22 is conveniently plugged into the sliding groove 411. This arrangement can make it easier to load and unload the locking hook 2 in the mounting shell 41.

[0071] In some embodiments, the supporting portion 21 is connected to the mounting shell 41 through the second elastic member 422, and the second elastic member 422 provides an elastic force in the direction of the supporting portion 21 approaching or moving away from the locking block body 1; through the arrangement of the second elastic member 422, the movement stability of the overall structure formed by the lock hook 2 and the supporting portion 21 when being impacted and squeezed by the locking block body 1 can be further improved. It should be understood that the first elastic member 421 and the second elastic member 422 are arranged in the mounting shell 41 along the movement direction of the locking block body 1. When the main body 1 squeezes the lock hook 2, the overall structure formed by the lock hook 2 and the supporting part 21 can be supported by multiple elastic forces, thereby improving the movement stability.
