Technical Field

[0001] The invention relates to the field of automobile accessories, and in particular to an automobile seat unlocking switch. Background Art

[0002] There are currently many handle mechanisms for unlocking car seats, but in actual use, they require both a quick response and safety during use, while also requiring the least possible force to unlock.

[0003] In the prior art, for example, a handle mechanism for unlocking the second row seat backrest of a car disclosed in Chinese patent publication CN 210941461 U hinges the corner of the unlocking handle with the handle base through a rotating shaft through an L-shaped unlocking handle, and sets a cable head mounting hole for mounting the cable inner core head on the short side of the unlocking handle, so that the unlocking handle can rotate smoothly relative to the handle base, reducing the pulling force required for unlocking. However, it is necessary to continuously pull the handle when unlocking, and there is no restriction or force feedback after unlocking, which is inconvenient to use. Summary of the invention

[0004] The purpose of the present invention is to provide a car seat unlocking switch to solve the problem in the prior art that the handle needs to be pulled continuously when unlocking, there is no restriction and force feedback after unlocking, and it is inconvenient to use.

[0005] A car seat unlocking switch comprises: a body, an unlocking handle, and a warning stop point, wherein the unlocking handle is rotatably connected to the body, and the warning stop point is rotatably connected to the body.

[0006] Preferably, the unlocking handle is connected to the body via a handle rotating shaft pin, and the warning stop point is connected to the body via a structural rotating shaft pin. The unlocking handle and the warning stop point can be smoothly rotated by the handle rotating shaft pin and the structural rotating shaft pin.

[0007] Preferably, thrust caps are provided at the connection places between both ends of the handle rotating shaft pin and the structure rotating shaft pin and the body.

[0008] Preferably, a handle torsion spring is provided on the handle rotating shaft pin, and a structural torsion spring is provided on the structural rotating shaft pin. The handle torsion spring is used to limit the rotation of the unlocking handle, and the structural torsion spring is used to limit the rotation of the warning stop point.

[0009] Preferably, the unlocking handle includes a buckle part, a connecting part, and a rotating part. The connecting part is an arc-shaped structure, one end of which is connected to the buckle part, and the other end is connected to the rotating part. A hidden space is formed at the junction of the buckle part and the connecting part.

[0010] Preferably, the connecting portion is provided with a plurality of transverse reinforcing ribs and longitudinal reinforcing ribs, which can reduce the weight of the part while ensuring the strength of the part.

[0011] Preferably, a limiting portion is provided on the longitudinal reinforcing rib, and the limiting portion is used to limit the warning stop point to keep the switch in an unlocked state.

[0012] Preferably, a placement slot is provided on the connecting portion, the placement slot is L-shaped, and a torsion arm of the structural torsion spring is in the placement slot. The placement slot is used to place a torsion arm of the structural torsion spring, and can control the rotation of the warning stop point.

[0013] Preferably, the outer side of the L-shaped corner of the placement groove is an arc shape, and the inner side of the corner is a right angle.

[0014] Preferably, the inner side edge of the corner of the placement groove constitutes a return portion. The return portion can pull the torsion arm of the structural torsion spring to make the warning stop point leave the limit portion and switch the switch to a locked state.

[0015] Beneficial effects:

[0016] 1. The present invention provides an unlocking switch for a car seat, which has a locked state and an unlocked state. The unlocking handle in the unlocked state is stably limited, and there is no need to continuously pull the handle, which saves the force used in unlocking and is safer in use.

[0017] 2. The prior art requires continuous pulling of the handle to keep the unlocked state when unlocking the car seat unlocking switch. At the same time, there is no restriction and force feedback after unlocking, and it is not possible to feel whether it has been unlocked, which is inconvenient to use. In the present invention, when unlocking the switch, you only need to pull the unlocking handle to the maximum position. The unlocking handle releases the restriction on the warning stop point, and the warning stop point is close to the connection part of the unlocking handle; when the unlocking handle is released, the handle torsion spring makes the unlocking handle rebound, and the warning stop point is just stuck on the limit part, and the switch is in the unlocked state. During the unlocking process, you only need to pull the unlocking handle once, and there is no need to continuously pull the handle. At the same time, it is restricted to a fixed position after unlocking, which ensures the stability of unlocking.

[0018] 3. Conventional car seat unlocking switches can be locked by releasing the hand, but in the present invention, because the support of the warning stop point will not be automatically locked but will remain unlocked, a return part is provided. Only when the unlocking handle is pulled again and released in the unlocked state, the return block below will interact with the torsion arm of the structural torsion spring when the unlocking handle rebounds again, thereby forming a linkage with the warning stop point. The return part will press the torsion arm of the structural torsion spring, press the warning stop point into the hidden groove, and the switch will return to the locked state. This locking method can effectively prevent accidental touches and reset the entire switch safely.

[0019] 4. The placement groove is an L-shaped structure. The outer side of the L-shaped corner is an arc-shaped structure, and the inner side of the corner is a right-angled structure. The arc-shaped structure mainly plays a guiding role. When the switch needs to be unlocked, the torsion arm of the structural torsion spring can slide through the arc; the right-angled structure mainly plays a limiting role. When the switch needs to be locked, the torsion arm of the structural torsion spring is subjected to the force transmitted by the right-angled side, which will not cause the torsion arm of the structural torsion spring to slide.

[0020] 5. There are multiple transverse and longitudinal reinforcement ribs on the connection part, which can reduce the weight of the parts as much as possible without reducing the overall strength, which is beneficial to the stability of the product structure. At the same time, the limit part is formed by the height difference of the longitudinal reinforcement ribs, and cooperates with the unlocking handle and the warning stop point to keep the switch unlocked.

[0030] Embodiment 1:

[0031] like Figure 1-5 The illustrated embodiment of a car seat unlocking switch comprises: a body 1, an unlocking handle 2, and a warning stop point 3. The unlocking handle 2 is rotatably connected to the body 1 through a handle rotating shaft pin 4, and the warning stop point 3 is rotatably connected to the body 1 through a structural rotating shaft pin 5. Thrust caps 6 are provided at the connection points between the two ends of the handle rotating shaft pin 4 and the structural rotating shaft pin 5 and the body 1. The unlocking handle 2 and the warning stop point 3 can be smoothly rotated by the handle rotating shaft pin 4 and the structural rotating shaft pin 5. A handle torsion spring 7 is provided on the handle rotating shaft pin 4, and a structural torsion spring 8 is provided on the structural rotating shaft pin 5. The handle torsion spring 7 is used to limit the rotation of the unlocking handle 2, and the structural torsion spring 8 is used to limit the rotation of the warning stop point 3.

[0032] The unlocking handle 2 includes a handle portion 21, a connecting portion 22, and a rotating portion 23. The connecting portion 22 is an arc-shaped structure, one end of which is connected to the handle portion 21, and the other end is connected to the rotating portion 23. A hidden space is formed at the junction of the handle portion 21 and the connecting portion 22. When the switch is in a locked state, the warning stop point 3 will be in the hidden space.

[0033] The connecting portion 22 is provided with a plurality of transverse reinforcing ribs 24 and longitudinal reinforcing ribs 25, and a limiting portion 26 is provided on the longitudinal reinforcing ribs 25. The reinforcing ribs can reduce the weight of the part while ensuring the strength of the part. The limiting portion 26 is used to limit the warning stop point 3 and keep the switch in an unlocked state.

[0034] A placement slot 27 is provided on the connection portion 22. The placement slot 27 is L-shaped, and a torsion arm of the structural torsion spring 8 is in the placement slot 27. The outer side of the L-shaped corner of the placement slot 27 is an arc shape, and the inner side of the corner is a right angle. The inner side of the corner of the placement slot 27 constitutes a return portion 28. The placement slot 27 is used to place a torsion arm of the structural torsion spring 8, which can control the rotation of the warning stop point 3. The return portion 28 can pull the torsion arm of the structural torsion spring 8 to make the warning stop point 3 leave the limit portion 26 and switch the switch to the locked state.

[0035] Working principle: when unlocking is required, pull the unlocking handle 2 to the maximum position, the unlocking handle 2 releases the restriction on the warning stop point 3, the structural torsion spring 8 bounces the warning stop point 3 to a free state, and after releasing the unlocking handle 2, the handle torsion spring 7 pulls the unlocking handle 2 to rotate, and the torsion arm of the structural torsion spring 8 slides on the arc-shaped corner of the placement groove 27, driving the warning stop point 3 to be close to the unlocking handle 2, so that the warning stop point 3 is just stuck on the limit part 26, and the unlocking handle 2 is lifted to keep it unlocked. The unlocking state of the unlocking switch is the same each time it is unlocked, and the unlocking process is stable. The operator can accurately complete the correct operation without paying attention, and it has high stability.

[0036] When the switch needs to be locked in the unlocked state, the unlocking handle 2 is pulled to the maximum again and released. When the unlocking handle 2 rebounds again, the return portion 28 below presses the torsion arm of the structural torsion spring 8, thereby forming a linkage with the warning stop point 3, pressing the warning stop point 3 into the hidden groove, and the switch returns to the locked state. This locking method can effectively prevent accidental touches and reset the entire switch safely.
