Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a quick-release mechanism with adjustable travel, a seat, and a vehicle. Background Technology

[0002] Currently, automobiles are becoming increasingly intelligent, and seat configurations are also becoming more sophisticated. Within a seat, there is a need for two components requiring electrical or pneumatic connections to be quickly plugged in and out, reliably locked, and able to move relative to each other within a certain range. For example, the adjustable headrest (especially those with speakers or electric adjustment functions) needs a stable electrical connection to the seat back. Furthermore, the wiring should be able to adapt to changes in travel when adjusting the headrest height, and in the event of a collision or other emergency, the headrest should be able to quickly detach to avoid injury to the occupants.

[0003] Existing quick-connect solutions typically have the following drawbacks: 1) The locking mechanism is complex and has many parts, resulting in cumbersome assembly, high costs, and slow production cycle; 2) The locking reliability is insufficient, and it is easy to loosen in a vibration environment; 3) The connector usually needs to be fully inserted (extreme position) to conduct electricity, and cannot provide a stable electrical connection in the middle stroke, which limits the adjustment range; 4) In the non-connected state, the connector lacks effective limit, and is prone to abnormal noise due to vehicle bumps.

[0004] Therefore, a new type of quick-release mechanism is needed that is simpler in structure, has reliable locking, stable connection capability within the stroke, and can be quickly disengaged. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a quick-connect and unplug mechanism that is simple in structure, reliable in locking, allows for adjustment within the stroke, and enables rapid connection and unlocking.

[0006] This utility model further proposes a seat.

[0007] This utility model further proposes a vehicle.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An adjustable-stroke quick-connect mechanism includes a housing assembly and a connecting rod. The connecting rod has a first connector. The housing assembly contains a locking slider and a moving slider connected to the locking slider. The moving slider has a second connector that engages with the first connector. The lower part of the moving slider has a reset element. The locking slider can engage with the connecting rod. The connecting rod is used to drive the first connector to engage or disengage with the second connector. After the connecting rod carries the first connector into the housing assembly and engages with the locking slider, it can continue to drive the moving slider to move downward within the housing assembly, while maintaining the engagement of the first connector and the second connector.

[0010] Preferably, the connecting rod is provided with a locking groove, and the locking slider is provided with a locking protrusion that matches the locking groove.

[0011] Preferably, the housing assembly has a first guide ramp inside for guiding the locking slider to move laterally to engage with the connecting rod, and the lower part of the locking slider has a second guide ramp that matches the first guide ramp.

[0012] Preferably, the lower part of the locking slider is provided with two mutually parallel third guide slopes for connecting the moving slider.

[0013] Preferably, the motion slider is provided with two parallel fourth guide slopes connected to the third guide slope.

[0014] Preferably, the housing assembly includes a top cover and a housing body, wherein the top cover is fixed to the housing body by a snap-fit ​​method.

[0015] Preferably, the reset element is a compression spring, which is sleeved between the lower part of the moving slider and the bottom wall of the housing assembly.

[0016] Preferably, the first connector and the second connector are electrically connected or pneumatically connected.

[0035] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0036] Reference Figures 1 to 5 , Figure 1 This is a perspective view of the present invention. Figure 2 This is an exploded view of this utility model. Figure 3 This is a schematic diagram showing the connecting rod inserted into the housing but not locked, specifically when the connecting rod is in its highest position. Figure 4 This is a schematic diagram showing the connecting rod just after it has been inserted into the housing and locked in place. Figure 5 This is a schematic diagram of the connecting rod adjusting in the movement section of the housing, specifically a diagram showing the connecting rod moving downwards to its lowest position. This utility model provides a quick-release mechanism with adjustable stroke, including a housing assembly 1, a connecting rod 2, a first connector 3, a locking slider 4, a moving slider 5, a second connector 6, and a reset element 7. The housing assembly 1 has a hollow structure and internally houses the locking slider 4 and the moving slider 5 connected to it. The locking slider 4 and the moving slider 5 are connected and can move up and down within the housing assembly 1. The connecting rod 2 has the first connector 3, and the moving slider 5 has the second connector 6 that engages with the first connector 3. The first connector 3 and the second connector 6 can be electrically or pneumatically connected. The moving slider 5 has a reset element 7 at its lower part. The locking slider 4 can engage with the connecting rod 2. The connecting rod 2 is used to drive the first connector 3 and the second connector 6 to plug in or separate. After the connecting rod 2 carries the first connector 3 into the housing assembly 1 and engages with the locking slider 4, it can continue to drive the moving slider 5 to move downward within the housing assembly 1, while maintaining the first connector 3 and the second connector 6 in contact. This achieves an adjustable function within the stroke. In the locked state, the connecting parts (the first connector 3 and the second connector 6) can still move relative to each other within a certain range without disconnecting, expanding the application scenarios, such as the height adjustment of an adjustable headrest. As the connecting rod 2 moves downward, it compresses the reset element 7. When the connecting rod 2 is moved to the locked position by a reverse force and continues to move upward, the moving slider 5 is reset under the action of the reset element 7, and the locking slider 4 disengages from the connecting rod 2, thus unlocking.

[0037] In one embodiment, the connecting rod 2 is provided with a locking groove 21, the locking slider 4 is provided with a locking protrusion 41 that matches the locking groove 21, the housing assembly 1 is provided with a first guide slope 11 for guiding the locking slider 4 to move laterally to engage with the connecting rod 2, the lower part of the locking slider 4 is provided with a second guide slope 42 that matches the first guide slope 11, the lower part of the locking slider 4 is provided with two parallel third guide slopes 43 for connecting the moving slider 5, and the moving slider 5 is provided with two parallel fourth guide slopes 51 that connect to the third guide slopes 43.

[0038] When the connecting rod 2, carrying the first connector 3, is inserted into the locking slider 4, the connecting rod 2 drives the locking slider 4 to move downwards. Simultaneously, the second guide slope 42 of the locking slider 4, guided by the first guide slope 11, causes the locking slider 4 to move laterally inwards. The locking protrusion 41 engages with the locking groove 21 to form a lock. As the connecting rod 2 continues to move downwards, the locking slider 4 pushes the connected moving slider 5 downwards, i.e., the third guide slope 43 drives the fourth guide slope 51. The movement causes the moving slider 5 and the locking slider 4 to move downwards along the inner wall of the housing assembly 1 simultaneously. At the same time, since the locking slider 4 and the connecting rod 2 with the first plug 3 are locked, the first plug 3 and the second plug 6 are electrically or pneumatically connected. Thus, the first plug 3 and the second plug 6 can still move relative to each other within a certain range (the length range of the plugging channel formed inside the housing assembly 1) without disconnecting the connection even when locked, thus realizing the adjustable function within the stroke.

[0039] When the connecting rod 2 is subjected to a reverse force, i.e. when the connecting rod 2 is pulled out, the moving slider 5 is reset under the action of the reset element 7. The fourth guide slope 51 drives the third guide slope 43 to move. When the connecting rod 2 continues to move upward after moving to the locking position, the second guide slope 42 of the locking slider 4 is guided by the first guide slope 11 to make the locking slider 4 move laterally outward. The locking protrusion 41 disengages from the locking groove 21, and the locking slider 4 separates from the connecting rod 2, thus unlocking. The connecting rod 2 can be pulled out by continuing to pull the connecting rod up and down. The first plug 3 and the second plug 6 are disconnected from the electrical or pneumatic connection.

[0040] In one embodiment, the housing assembly 1 is made of engineering plastic and includes a top cover 12 and a housing body 13. The top cover 12 is fixed to the housing body 13 by a snap-fit ​​mechanism. In another embodiment, the reset element 7 is a compression spring, sleeved between the lower part of the motion slider 5 and the bottom wall of the housing assembly 1.

[0041] The seat according to this utility model includes the quick-connect mechanism in the above embodiments. For example, when the quick-connect mechanism is applied to the headrest, it can enable the headrest and backrest to be quickly connected and disconnected, thereby improving the user experience of the driver and passengers. More specifically, it can be the quick-connect and disconnection of electrical connections, air connections, and audio connections of electrically adjustable headrests, massage headrests, and music headrests.

[0042] According to the present invention, a vehicle including the seat in the above embodiments can improve the user experience of drivers and passengers.

[0043] The following will refer to Figures 1 to 5The working principle of this utility model will be explained.

[0044] Insertion and locking process: Insert the end of the connecting rod 2 with the first connector 3 downwards along the insertion channel. The top of the connecting rod 2 first contacts the moving slider 5 and pushes it downwards against the elastic force of the reset element 7. As the moving slider 5 moves downwards, its fourth guide slope 51 interacts with the third guide slope 43 of the locking slider 4, and the second guide slope 42 of the locking slider 4 interacts with the first guide slope 11, driving the locking slider 4 to move laterally towards the center synchronously. When the connecting rod 2 is inserted to the set depth, and its locking groove 21 moves to the position aligned with the locking protrusion 41 of the moving locking slider 4, the locking protrusion 41 quickly snaps into the locking groove 21 with a "click", achieving mechanical locking. At this time, the first connector 3 and the second connector 6 are electrically or pneumatically connected.

[0045] Stroke adjustment process: In the locked state, since the locking slider 4 is engaged in the locking groove 21, the connecting rod 2 can move up and down relative to the housing assembly 1 within the height range of the insertion channel inside the housing assembly 1. This movement will not cause the locking slider 4 to disengage, nor will it cause the first insertion member 3 to separate from the second insertion member 6 (insertion depth is sufficient). Therefore, it can be freely adjusted within a certain height range while maintaining electrical or circuit connection, and the function is normal.

[0046] Quick unlocking process: When disconnection is required (e.g., for maintenance or emergency), pull the connecting rod 2 upwards forcefully. Initially, the reset element 7 simultaneously moves the moving slider 5 upwards, and the locking slider 4 moves due to the upward force exerted by the moving slider 5. The connecting rod 2 moves upwards within the height range of the insertion channel inside the housing assembly 1. When the upward-moving locking slider 4 is about to reach the top of the housing assembly 1, the moving slider 5 pushes the locking slider 4 along the first guide slope 11. The locking slider 4 moves laterally outwards, the locking protrusion 41 disengages from the locking groove 21, and the locking slider 4 separates from the connecting rod 2, achieving quick unlocking. Continuing to pull the connecting rod 2 up and down allows for easy removal of the connecting rod 2, and the first insertion member 3 and the second insertion member 6 disconnect from their electrical or pneumatic connections.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
