Description

Technical Field

[0001] The present invention relates to the technical field of unlocking, and in particular provides an unlocking mechanism, a vehicle seat and a vehicle. Background Art

[0002] With the continuous development of various mechanical equipment, the application scenarios of unlocking mechanisms are also increasing. Taking the field of vehicle technology as an example, with the continuous development of vehicle technology, users are paying more and more attention to the comfort of vehicles, especially the comfort of vehicle seats. Therefore, vehicle seats have begun to be equipped with a variety of adjustment mechanisms, which not only include the traditional adjustment of the seat cushion and backrest, but also require the shoulders and head of the seat to have more adjustment functions. At the same time, it must have higher safety so that it can provide users with timely and effective protection measures in the event of an accident. Based on this, existing vehicles will also undergo various safety tests before leaving the factory. Among them, the most mainstream evaluation system is the low-speed rear impact test (i.e., C-NCAP whiplash test). In order to improve the safety performance of the vehicle and improve its score in the low-speed rear impact test, more and more vehicles will adopt the method of accelerating the head contact time, that is, designing an active contact mechanism on the seat frame to minimize the damage to the user caused by the collision.

[0003] Specifically, during a low-speed collision, the user's back will collide with the backrest along the vehicle's X-axis. At this point, the active contact mechanism needs to be triggered to implement the protective function. However, during normal vehicle use, the active contact mechanism needs to be locked. That is, the unlocking mechanism of the active contact mechanism needs to provide a locking effect during normal vehicle use to provide sufficient support strength, while unlocking is required during a low-speed rear-end collision, thereby triggering the active contact mechanism. Based on this requirement, many existing vehicles' active contact mechanisms use electronic devices to achieve the above effect. However, the response of electronic devices is delayed and prone to failure, threatening user safety.

[0004] Accordingly, the art requires a new unlocking mechanism, vehicle seat, and vehicle to solve or alleviate the above technical problems to a certain extent. Summary of the Invention

[0005] The present invention aims to solve or alleviate to a certain extent the above technical problem, namely, the problem that the existing unlocking mechanism is not effective when applied to the active contact mechanism of a vehicle.

[0006] In a first aspect, the present invention provides an unlocking mechanism, comprising a trigger member, a limiting member, a locking pin, a first connecting rod and a second connecting rod.

[0007] The first connecting rod, the second connecting rod and the triggering member are rotatably connected.

[0008] The trigger member is provided with a guide slot, the limiting member is connected to the second connecting rod and the limiting member is provided with a limiting slot, the first connecting rod is provided with a locking hole, and the locking pin can be passed through the guide slot, the limiting slot and the locking hole to achieve locking.

[0009] The guide slot is configured so that when the trigger member moves along a first direction, the guide slot can move relative to the locking pin along the first direction and thereby drive the locking pin to move along a second direction so that the locking pin escapes from the locking hole to achieve unlocking.

[0010] In a preferred technical solution of the above unlocking mechanism, the locking pin is provided with a first engaging structure, and the guide slot can be connected to the first engaging structure; and / or

[0011] The locking pin is further provided with a second engaging structure, and the limiting slot can be connected to the second engaging structure.

[0012] In the preferred technical solution of the unlocking mechanism, the guide slot includes a connected limiting section and a guide section.

[0013] The limiting section is arranged along the first direction, and the guiding section is arranged obliquely relative to the limiting section so as to be able to drive the locking pin to move along the second direction during the movement process.

[0014] In the preferred technical solution of the above unlocking mechanism, the triggering member includes a connected force-bearing section and a connecting section.

[0015] The force-bearing section and the connecting section are arranged vertically, and the guide slot is arranged on the connecting section.

[0016] In the preferred technical solution of the unlocking mechanism, a limiting slot is further provided on the second connecting rod.

[0017] The locking pin can also be inserted into the limiting sliding groove to limit its movement range in the unlocked state.

[0018] In the preferred technical solution of the above unlocking mechanism, the limiting sliding groove is arc-shaped.

[0019] In the preferred technical solution of the above unlocking mechanism, the unlocking mechanism further includes a reset member,

[0020] The reset component is configured to restore the trigger component to an initial state after the trigger component moves along the first direction.

[0021] In a preferred technical solution of the above unlocking mechanism, the reset member is a torsion spring.

[0022] In a second aspect, the present invention further provides a vehicle seat, comprising a fixing bracket, an adjustment module and an unlocking mechanism.

[0023] The unlocking mechanism is the unlocking mechanism described in any one of the above preferred technical solutions, the fixing bracket is rotatably connected to the first connecting rod of the unlocking mechanism, and the adjusting module is connected to the second connecting rod of the unlocking mechanism.

[0024] In a third aspect, the present invention further provides a vehicle, comprising the vehicle seat described in the above preferred technical solution.

[0025] In the case of adopting the above technical solution, the unlocking mechanism of the present invention includes a trigger member, a limiting member, a locking pin, a first connecting rod and a second connecting rod, wherein the first connecting rod, the second connecting rod and the trigger member are rotatably connected, the trigger member is provided with a guide slot, the limiting member is connected to the second connecting rod and the limiting member is provided with a limiting slot, the first connecting rod is provided with a locking hole, the locking pin can be inserted between the guide slot, the limiting slot and the locking hole to achieve locking, the guide slot is configured so that when the trigger member moves in a first direction, the guide slot can move relative to the locking pin in the first direction and thereby drive the locking pin to move in a second direction so that the locking pin is disengaged from the locking hole to achieve unlocking. Based on the above structural arrangement, the unlocking mechanism of the present invention achieves a movement in which the unlocking force is perpendicular to the unlocking direction. Different from the existing unlocking mechanism in which the unlocking force is parallel to the unlocking direction, its structure is more compact, and its unlocking process is non-destructive, which can achieve the effect of repeated use.

Furthermore, the unlocking mechanism is structurally designed for non-destructive unlocking, allowing for reuse after a low-speed rear-end collision. Furthermore, due to the provision of the reset member, the unlocking mechanism of the present invention not only automatically unlocks in the event of a low-speed rear-end collision, but also automatically resets after the collision, further enhancing ease of use.

[0046] The following describes optional embodiments of the present invention with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific applications. For example, the present invention does not impose any restrictions on the specific application objects of the unlocking mechanism. Although this preferred embodiment is described in conjunction with the unlocking of the UBA structure (i.e., the head and shoulder adjustment mechanism of the vehicle seat) of the vehicle, this is obviously not restrictive, and it can also be applied to other scenarios where the force direction is perpendicular to the unlocking direction; for example, the vehicle described in the present invention can be a car, a commercial vehicle, a bus, a truck, a fuel vehicle, an electric vehicle, or a hybrid vehicle, which is not restrictive. Such changes in specific application objects or specific types do not deviate from the basic principles of the present invention and therefore fall within the scope of protection of the present invention.

[0047] It should be noted that, in the description of the present invention, the terms "upper", "lower", "left", "right" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of description, and do not indicate or imply that the structure must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0048] In addition, it should be noted that the directional terms used in this article, such as "X direction" and "Y direction", are based on the direction of the vehicle after the component is installed on the vehicle; among them, the X direction refers to the length direction of the vehicle, and the Y direction refers to the width direction of the vehicle.

[0049] See first Figure 1 ,like Figure 1 As shown, the vehicle seat provided by the present invention includes an unlocking mechanism 1, a fixing bracket 2, a UBA adjustment module 3 and a UBA adjustment rotating shaft 4. The unlocking mechanism 1 is connected to both ends of the UBA adjustment module 3 through two symmetrical structures ( Figure 1(Only the right side is shown in the figure), and the unlocking mechanism 1 is connected to the fixed bracket 2 via the UBA adjustment shaft 4, and the fixed bracket 2 is connected to the main body of the vehicle seat. It should be noted that the present invention does not impose any restrictions on the specific configuration of the unlocking mechanism 1 when applied to a vehicle seat, and those skilled in the art can customize it according to actual use requirements; for example, the specific structure of the fixed bracket 2, UBA adjustment module 3, and UBA adjustment shaft 4 can be adjusted according to actual use requirements.

[0050] Next see Figures 1 to 6 The specific structure of the unlocking mechanism 1 of the present invention is described in detail. Figures 1 to 6 As shown, the unlocking mechanism 1 of the present invention includes a trigger member 11, a limiting member 12, a locking pin 13, a rotating shaft 14, a first connecting rod 15 and a second connecting rod 16, wherein the rotating shaft 14 is rotatably connected to the first connecting rod 15, the second connecting rod 16 and the trigger member 11, and a guide slot 1122 is provided on the trigger member 11, the limiting member 12 is connected to the second connecting rod 16 and a limiting slot 121 is provided on the limiting member 12, and the length direction of the guide slot 1122 and the length direction of the limiting slot 121 are perpendicularly arranged in the locked state. Of course, the vertical arrangement is only an optimal arrangement, as long as the angle formed by the length directions of the two can enable the limiting slot 121 to generate a pressing force on the locking pin 13 when the locking pin 13 is in the locked state. The first connecting rod 15 is provided with a locking hole 151, and the locking pin 13 can be inserted between the guide slot 1122, the limit slot 121 and the locking hole 151 to achieve locking. The guide slot 1122 is configured so that when the trigger member 11 moves along the first direction, the guide slot 1122 can move relative to the locking pin 13 along the first direction and thereby drive the locking pin 13 to move along the second direction so that the locking pin 13 is disengaged from the locking hole 151 to achieve unlocking. The first direction and the second direction are perpendicular. In this embodiment, refer to Figure 1The first direction is inward, and the second direction is horizontally to the left. Of course, the perpendicular arrangement of the first and second directions is merely a preferred configuration, as long as the torque between the trigger member 11 and the locking pin 13 is greater than zero, allowing the trigger member 11 to move the locking pin 13 through the guidance of the guide slot 1122 to unlock the trigger member 11. Furthermore, it should be understood that the present invention does not impose any restrictions on the driving method for the movement of the trigger member 11 in the first direction. Preferably, the method is driven by the user's backward force generated by an impact, although electric driving is also possible. Furthermore, it should be noted that the present invention does not impose any restrictions on the specific structure of the trigger member 11, the limiting member 12, the locking pin 13, the rotating shaft 14, the first connecting rod 15, and the second connecting rod 16. Furthermore, the first connecting rod 15, the second connecting rod 16, and the trigger member 11 may be rotatably connected not via the rotating shaft 14, but rather through the coordination of their own structures. Persons skilled in the art can customize the configuration based on actual usage requirements, as long as the above functions are met.

[0051] Furthermore, if Figure 1 and 3 As shown, the trigger member 11 is connected to a force-bearing section 111 and a connecting section 112, and the two connecting sections 112 are connected to the force-bearing section 111 from both ends respectively, and the force-bearing section 111 and the connecting section 112 are vertically arranged. In this preferred embodiment, the force-bearing section 111 and the connecting section 112 are both long strip structures, a part of the connecting section 112 extends outward and bends to form a bent section 1121, and a guide slot 1122 is provided on the bent section 1121, and the guide slot 1122 is a through slot structure with one end open, the locking pin 13 can move in the guide slot 1122, and a first connecting hole 1123 is also provided on the connecting section 112 for passing the rotating shaft 14.

[0052] It should be noted that the present invention does not impose any restrictions on the specific structure of the trigger component 11 and the guide slot 1122. Those skilled in the art can set it according to actual usage requirements, as long as the trigger component 11 is provided with a guide slot 1122 and when the trigger component 11 moves along the first direction, the guide slot 1122 can move relative to the locking pin 13 along the first direction and thereby drive the locking pin 13 to move along the second direction so that the locking pin 13 disengages from the locking hole 151 to achieve unlocking; for example, the guide slot 1122 can also be directly provided on the main body of the connecting section 112, or even directly provided on the force-bearing section 111; for another example, the guide slot 1122 can also be a slot with closed ends, or a sinking groove structure.

[0053] As a preferred setting mode, the guide slide 1122 includes a connected limiting section 11221 and a guiding section 11222, the limiting section 11221 is an end close to the opening, and the guiding section 11222 is an end away from the opening, and the limiting section 11221 is set along the first direction, and the guiding section 11222 is inclined relative to the limiting section 11221 so as to be able to drive the locking pin 13 to move along the second direction during the movement; wherein, the limiting section 11221 is set straight to ensure that the trigger member 11 will not drive the locking pin 13 when it moves slightly along the first direction. The pin 13 moves in the second direction, thereby effectively ensuring the locking effect of the unlocking mechanism 1 during daily use. This arrangement can also effectively prevent the locking pin 13 from dislodging from the guide slot 1122, thereby effectively ensuring the reliability of unlocking. The guide section 11222 is arranged at an angle relative to the limiting section 11221. After the trigger member 11 has a large displacement in the first direction and enters the guide section 11222, the inclined guide section 11222 can guide the locking pin 13 to move in the second direction, so that the locking pin 13 disengages from the locking hole 151 to achieve unlocking. In addition, it should be noted that the present invention does not impose any restrictions on the specific shapes and sizes of the limiting section 11221 and the guide section 11222. Those skilled in the art can set them according to actual usage requirements.

[0054] Continue reading Figure 2 and Figure 6 In this embodiment, the limiting member 12 is a plate-like structure, and the limiting slot 121 is a through-slot structure formed at one end of the limiting member 12. One end of the limiting slot 121 is open. The limiting member 12 is pressed onto the locking pin 13 through the limiting slot 121 to achieve the limiting effect. It should be noted that the present invention does not impose any restrictions on the specific structure of the limiting member 12. Those skilled in the art can customize it according to actual use requirements, as long as the limiting slot 121 can be provided on it. As a preferred configuration, three circular ring structures are spaced apart on the locking pin 13. These three circular ring structures form a first insertion slot 131 and a second insertion slot 132. Of course, the specific formation method of the first insertion slot 131 and the second insertion slot 132 is not limited, and they can also be formed by slotting. The guide groove 1122 can be inserted into the first insertion slot 131, and the limiting slot 121 can be inserted into the second insertion slot 132 to better achieve the locking effect. It can be understood that although the engagement structure described in this preferred embodiment adopts the setting mode of the plug-in slot, this is only a preferred setting mode. Those skilled in the art can obviously also improve the reliability of locking through other engagement structures, such as with the help of a slide rail structure, or directly achieve locking through friction and extrusion. This is not restrictive.

[0055] Continue reading Figure 2 、 4In the preferred embodiment, the first connecting rod 15 is a strip-shaped structure, and the strip-shaped structure is also provided with multiple bending structures to achieve avoidance. The two ends of the first connecting rod 15 are respectively provided with a second connecting hole 152 and a mounting hole 153. The second connecting hole 152 is used to pass the rotating shaft 14, and the mounting hole 153 is used to pass the UBA adjustment rotating shaft. The locking hole 151 is provided between the second connecting hole 152 and the mounting hole 153 to better achieve locking. The locking hole 151, the second connecting hole 152 and the mounting hole 153 are all through-hole structures. It should be noted that the present invention does not impose any restrictions on the specific structure of the first connecting rod 15 and the specific setting positions of the locking hole 151, the second connecting hole 152 and the mounting hole 153, and the present invention does not limit the specific connection method between the first connecting rod 15 and the fixed bracket 2. Those skilled in the art can set it according to actual use requirements.

[0056] Further, in this preferred embodiment, see Figure 2 In the middle position, a limiting slot 161 is provided at the bottom end of the second connecting rod 16, and the locking pin 13 can also be inserted into the limiting slot 161 to limit its range of movement in the unlocked state. That is, the locking pin 13 is inserted into the guide slot 1122, the limiting slot 121, the limiting slot 161, and the locking hole 151 from left to right, and the locking end 133 of the locking pin 13 can be released from the locking hole 151. It should be noted that the vertical guide length of the guide section 11222 needs to be greater than the length of the locking end 133 to effectively ensure that the locking end 133 of the locking pin 13 can be released from the locking hole 151 smoothly. In addition, one end of the limiting member 12 is connected to the middle portion of the second connecting rod 16. The second connecting rod 16 is also provided with a third connecting hole 162 for passing the rotating shaft 14. The rotating shaft 14 is sequentially passed through the first connecting hole 1123, the third connecting hole 162, and the second connecting hole 152 from left to right. The top of the second connecting rod 16 is provided with a connecting slot 163. The connecting slot 163 has openings at one end and one side. The unlocking mechanism 1 is connected to the UBA adjustment module 3 through the connecting slot 163. Of course, it is understood that the present invention does not impose any restrictions on the specific connection method between the unlocking mechanism 1 and the UBA adjustment module 3. Those skilled in the art can customize it according to actual usage requirements.

[0057] Specifically, the limiting slide 161 includes two interconnected parts: a through hole 1611 and a recessed groove 1612. The through hole 1611 is used to ensure that the locking pin 13 can pass through the second connecting rod 16 and enter the locking hole 151, while the recessed groove 1612 is used to limit its range of movement in the unlocked state. When the locking pin 13 moves leftward and disengages from the locking hole 151, the trigger member 11 continues to swing relative to the second connecting rod 16, causing the locking end 133 of the locking pin 13 to enter the recessed groove 1612. The through hole 1611 and the recessed groove 1612 preferably form an arc-shaped structure to ensure smooth guidance. It should be noted that the present invention does not impose any restrictions on the specific structure and shape of the limiting slide 161. Those skilled in the art can customize it according to actual usage requirements, as long as the limiting slide 161 can limit the range of movement of the locking pin 13 in the unlocked state.

[0058] Continue reading Figure 1 and 2 The unlocking mechanism 1 of the present invention further includes a reset member 141. This reset member 141 is configured to restore the trigger member 11 to its initial state after movement in the first direction, i.e., to a state where the locking pin 13 can be inserted into the locking hole 151. It should be noted that the present invention does not impose any restrictions on the specific type of reset member 141, as long as it can achieve the reset effect; for example, the reset member 141 can be a reset motor. As a preferred configuration, the reset member 141 is a torsion spring mounted on the rotating shaft 14, achieving both reset and energy-saving effects.

[0059] Based on the situation that the unlocking mechanism 1 in the above preferred embodiment is applied to a vehicle seat, refer to Figure 2 In the orientation of the middle, when the unlocking mechanism 1 is in the locked state, the left end of the locking pin 13 is stuck in the guide slot 1122, and its locking end 133 locks the first connecting rod 15 and the second connecting rod 16 through the hole-axis cooperation. The limiting member 12 presses the locking pin 13 through the limiting slot 121 to achieve Y-direction limitation, thereby realizing the locking function; during the unlocking process, when the vehicle encounters a low-speed rear collision, the back of the human body contacts and hits the trigger member 11 to generate a clockwise torque around the rotating shaft 14, which drives the reset member 141 to deform, and the trigger member 11 is located at the bottom of the vehicle. The guide slot 1122 on the component 11 drives the locking pin 13 to rotate, and at the same time, the locking pin 13 can be pulled out in the Y direction, thereby realizing the unlocking function. The moving range after unlocking is limited by the limiting slot 161; during resetting, when the back of the human body has no large force on the trigger component 11, under the action of the counterclockwise torque generated by the resetting component 141, the trigger component 11 drives the locking pin 13 to return along the guide slot 1122, and in the whole process, the Y direction of the locking pin 13 is always pressed by the limiting component 12 to achieve limitation.

[0060] It should be noted that the above preferred embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art may adjust the above settings so that the present invention can be applied to more specific application scenarios.

[0061] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0062] Furthermore, those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of the present invention and form different embodiments, such as the flexible selection between different implementations of the switching portion and the first movable portion. In the claims of the present invention, any of the claimed embodiments may be used in any combination.

[0063] Thus far, the technical solutions of the present invention have been described in conjunction with the optional embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
