Description

Technical Field

[0001] The invention relates to a single-side locking and unlocking type automobile seat slide rail. Background Art

[0002] With the improvement of living standards, people have more demands on the functions of car seats. It is no longer just for sitting, but also requires the ability to adjust forward and backward. The forward and backward adjustment function of the seat provides people with a better experience of riding comfort.

[0003] The forward and backward adjustment function of car seats has gradually become a basic function of most cars. It can be divided into electric adjustment and manual adjustment. The electric adjustment slide rail locking and unlocking mechanism mainly includes a motor, a reduction gearbox, and a screw, while the manual adjustment locking and unlocking mechanism mainly includes some non-electric components. Compared with manual adjustment, electric adjustment requires the use of a motor, a reduction gearbox, and a screw. Although the structure is simple, the cost is higher.

[0004] At present, most of the manually adjustable slide rails on the market are of the vertical latch type. Under bumpy working conditions, the vertical spline structure is prone to move up and down, resulting in locking failure. On the other hand, the vertical latch type requires sufficient space in the longitudinal direction, which requires increasing the height of the slide rail and machining grooves in the lower slide rail, making the slide rail difficult to machine and increasing the manufacturing cost.

[0005] In addition, the manual slide rail also has a horizontal plug-in lock type. The horizontal plug-in lock type requires slots to be processed on the longitudinal sides of the upper and lower slide rails for plug-in locking, and the splines are arranged in coordination with the corresponding slots. The splines on both sides are not synchronized when unlocking and locking, which can easily cause jamming and abnormal noise during operation. Summary of the invention

[0049] The present invention is described in detail below in conjunction with the embodiments and the accompanying drawings to help those skilled in the art better understand the inventive concept of the present invention. However, the protection scope of the claims of the present invention is not limited to the following embodiments. For those skilled in the art, all other embodiments obtained without creative work without departing from the inventive concept of the present invention belong to the protection scope of the present invention.

[0050] In the description of the present invention, it should be clarified that the directional terms "up, down, left, right, front, back, top, bottom" are only relative concepts in terms of direction. They are for the convenience of describing the present invention or simplifying the description, rather than indicating or implying a specific direction that the present invention must have. Therefore, they cannot be understood as limitations on the present invention.

[0051] Embodiment 1

[0052] like Figures 1 to 3 , Figure 6-3 and Figure 7-3 As shown, the present invention discloses a single-side locking and unlocking type automobile seat slide rail, comprising a lower slide rail 1 and an upper slide rail 2 that slide with each other, and a locking and unlocking mechanism disposed in the inner cavity of the upper slide rail 2, characterized in that: the locking and unlocking mechanism is composed of an operating component and an execution component;

[0053] The lower slide rail 1 and the upper slide rail 2 both have their left side or their right side as opening sides, the opening side of the lower slide rail 1 is provided with a plurality of lower slide rail clamping holes 1a arranged at intervals in the front-to-back direction, and the opening side of the upper slide rail 2 is provided with an upper slide rail clamping hole 2a;

[0054] The actuator assembly is provided with a lock card 6, and the lock card 6 is provided with a latching tooth 6-1 facing the opening side, and the latching tooth 6-1 of the lock card 6 is kept inserted in the upper slide rail latching hole 2a of the upper slide rail 2;

[0055] The operating component can drive the lock card 6 of the actuator component to move between the locked position and the unlocked position in the left and right direction, so that: when the lock card 6 moves to the locked position, the latch tooth 6-1 of the lock card 6 passes through the upper slide rail latch hole 2a and is inserted into the lower slide rail latch hole 1a of the lower slide rail 1. At this time, the single-sided locking and unlocking type automobile seat slide of the present invention is in a locked state, that is, the lower slide rail 1 and the upper slide rail 2 are locked by the lock card 6 and cannot slide relative to each other. When the lock card 6 moves to the unlocked position, the latch tooth 6-1 of the lock card 6 is only inserted into the upper slide rail latch hole 2a and is separated from the lower slide rail latch hole 1a. At this time, the single-sided locking and unlocking type automobile seat slide of the present invention is in an unlocked state, that is, the lower slide rail 1 and the upper slide rail 2 are not locked by the lock card 6 and can slide relative to each other.

[0056] The working principle of the one-side locking and unlocking type automobile seat slide rail of the present invention is as follows:

[0057] Slide rail unlocking operation:

[0058] When the single-sided locking and unlocking type automobile seat slide of the present invention is in a locked state, the locking card 6 is driven by the operating component to move to the unlocked position toward the side of the opening, so that the locking tooth 6-1 of the locking card 6 is only inserted into the upper slide rail clamping hole 2a of the upper slide rail 2 and separated from the lower slide rail clamping hole 1a of the lower slide rail 1, so as to release the locking of the lower slide rail 1 and the upper slide rail 2 by the locking card 6, and complete the unlocking of the slide rail. At this time, the single-sided locking and unlocking type automobile seat slide of the present invention is in an unlocked state, and the upper slide rail 2 can be slid to adjust the relative position between the upper slide rail 2 and the lower slide rail 1.

[0059] Slide rail locking operation:

[0060] After completing the adjustment of the relative position between the upper slide rail 2 and the lower slide rail 1, the locking card 6 is driven by the operating component to move toward the opening side to the locking position, so that the locking tooth 6-1 of the locking card 6 is simultaneously inserted into the upper slide rail clamping hole 2a of the upper slide rail 2 and the lower slide rail clamping hole 1a of the lower slide rail 1, so that the locking card 6 can lock the lower slide rail 1 and the upper slide rail 2, completing the locking of the slide rails, so that the single-sided locking and unlocking type automobile seat slide rail of the present invention re-enters the locked state.

[0061] Among them, when the single-sided locking and unlocking car seat slide rail of the present invention is used, in principle, the lower slide rail 1 can be fixed on the car floor and the car seat can be fixed to the upper slide rail 2, or the upper slide rail 2 can be fixed to the car floor and the car seat can be fixed to the lower slide rail 1. However, it is undoubtedly preferred to fix the lower slide rail 1 to the car floor and the car seat to the upper slide rail 2, so that the locking and unlocking mechanism can move with the upper slide rail 2 and the car seat, which is more convenient for passengers to operate the locking and unlocking mechanism.

[0062] Embodiment 2

[0063] On the basis of the above-mentioned embodiment 1, this embodiment 2 also adopts the following preferred implementation manner:

[0064] like Figure 1 to Figure 7-3 As shown, the operating component drives the lock card 6 of the actuator component to move between the locked position and the unlocked position along the left-right direction as follows:

[0065] The actuator assembly is also provided with a control handle 4, a support plate 5 and a roller 7;

[0066] The support plate 5 is fixed to the upper slide rail 2, the lock card 6 is located on the top surface of the support plate 5, the roller 7 is located above the lock card 6, and the lower end of the roller 7 is rotatably mounted on the lock card 6;

[0067] A control slide 4a is provided on the bottom surface of the rear end of the control handle 4. The extension mode of the control slide 4a can be arbitrary, as long as it meets the following conditions: the control slide 4a has a locking section 4a1 and an unlocking section 4a2 located at different positions in the front-to-back direction, and the locking section 4a1 is closer to the opening side of the upper slide rail 2 than the unlocking section 4a2, that is, if the opening side is the left side, the locking section 4a1 is closer to the left side than the unlocking section 4a2, which is also Figure 1 to Figure 7-3In the case shown, on the contrary, if the opening side is the right side, the locking segment 4a1 is closer to the right side relative to the unlocking segment 4a2, and the relevant drawings of this case are not provided in the present invention;

[0068] The rear end of the control handle 4 cooperates with the roller 7 so that the upper end of the roller 7 is located in the control slide 4a, and the roller 7 can roll between the locking section 4a1 and the unlocking section 4a2 along the extending direction of the control slide 4a, so that: the latch tooth 6-1 of the lock card 6 is kept inserted in the latch hole 2a of the upper slide rail, and under the limiting effect on the lock card 6, the movement of the control handle 4 in the front-to-back direction can drive the lock card 6 to move in the left-to-right direction on the support plate 5 through the roller 7, and when the roller 7 is located in the locking section 4a1, the lock card 6 moves to the locking position, and when the roller 7 is located in the unlocking section 4a2, the lock card 6 moves to the unlocking position;

[0069] The operating assembly can drive the control handle 4 to move in the front-rear direction, so that the roller 7 can roll between the locking section 4a1 and the unlocking section 4a2 relative to the control handle 4 to drive the lock card 6 to move between the locking position and the unlocking position in the left-right direction.

[0070] When the actuator described in the second embodiment of the present invention is used, the working principle of the single-side locking and unlocking automobile seat slide rail of the present invention is as follows:

[0071] Slide rail unlocking operation:

[0072] When the single-sided locking and unlocking type automobile seat slide of the present invention is in a locked state, the control handle 4 is driven to move by the operating component, so that the roller 7 rolls from the locking section 4a1 to the unlocking section 4a2 relative to the control handle 4, and drives the lock card 6 to move to the unlocking position away from the opening side, so that the locking tooth 6-1 of the lock card 6 is only inserted into the upper slide rail clamping hole 2a of the upper slide rail 2 and separated from the lower slide rail clamping hole 1a of the lower slide rail 1, so as to release the locking of the lower slide rail 1 and the upper slide rail 2 by the lock card 6, and complete the unlocking of the slide rail. At this time, the single-sided locking and unlocking type automobile seat slide of the present invention is in an unlocked state, and the upper slide rail 2 can be slid to adjust the relative position between the upper slide rail 2 and the lower slide rail 1.

[0073] Slide rail locking operation:

[0074] After completing the adjustment of the relative position between the upper slide rail 2 and the lower slide rail 1, the control handle 4 is driven to move by the operating component, so that the roller 7 rolls from the unlocking section 4a2 to the locking section 4a1 relative to the control handle 4, driving the lock card 6 to move toward the opening side to the locking position, so that the locking tooth 6-1 of the lock card 6 is simultaneously inserted into the upper slide rail card hole 2a of the upper slide rail 2 and the lower slide rail card hole 1a of the lower slide rail 1, so that the lock card 6 can lock the lower slide rail 1 and the upper slide rail 2, completing the locking of the slide rails, so that the single-sided locking and unlocking type automobile seat slide rail of the present invention re-enters the locked state.

[0075] The locking segment 4a1 and the unlocking segment 4a2 are located at different positions in the front-to-back direction, which means that any one of the locking segment 4a1 and the unlocking segment 4a2 can be located at the front, and it is only necessary to adjust the direction in which the operating component drives the control handle 4 to move when unlocking, that is:

[0076] In the case where the unlocking section 4a2 is located in front of the locking section 4a1 (i.e., the case shown in the drawings of the present invention), the operating assembly drives the control handle 4 to move backward to unlock the single-side locking and unlocking type automobile seat slide rail of the present invention;

[0077] When the locking section 4a1 is located in front of the unlocking section 4a2 (the present invention does not provide relevant drawings for this situation), the operating component drives the control handle 4 to move forward to unlock the single-sided locking and unlocking type automobile seat slide rail of the present invention.

[0078] Among them, preferably: Figure 4 As shown, the control slide 4a extends along an arc direction between the locking section 4a1 and the unlocking section 4a2, so that the locking and unlocking operations of the slide rail are smoother.

[0079] Embodiment 3

[0080] On the basis of the above-mentioned embodiment 2, this embodiment 3 also adopts the following preferred implementation manner:

[0081] like Figure 2 As shown, at least one of the left and right sides of the upper slide rail 2 is provided with a limiting slide groove 2b extending in the front-to-back direction;

[0082] The actuator assembly is also provided with a limit pin 3, which is fixed to the front end of the control handle 4, and the limit pin 3 is slidably installed in the limit slot 2b of the upper slide rail 2 (for the case where the limit slot 2b is only provided on the left or right side of the upper slide rail 2, one end of the limit pin 3 is slidably installed in the limit slot 2b, and for the case where the limit slots 2b are provided on both sides of the upper slide rail 2, the two ends of the limit pin 3 are respectively slidably installed in the two limit slots 2b).

[0083] Thus, by utilizing the guiding and limiting effect of the limiting slide groove 2b on the limiting pin shaft 3, the parallelism of the control handle 4 moving in the front-to-back direction can be ensured, and the front-to-back movement of the control handle 4 can be prevented from exceeding the limit, so as to ensure that the roller 7 only rolls between the locking section 4a1 and the unlocking section 4a2.

[0084] Embodiment 4

[0085] On the basis of the above-mentioned embodiment 2, this embodiment 4 also adopts the following preferred implementation manner:

[0086] like Figure 2 As shown, the control handle 4 is provided with bosses 4-1 on the left and right sides of its rear end, so that: the two bosses 4-1 of the control handle 4 are in contact with the upper slide rail 2, and a gap is left between the rest of the control handle 4 except the bosses 4-1 and the upper slide rail 2.

[0087] Therefore, on the one hand, the boss 4 - 1 can play a limiting role to ensure that the control handle 4 moves in the front-to-back direction without shaking left and right. On the other hand, there is a contact surface between the control handle 4 and the upper slide rail 2 to avoid being too large.

[0088] Embodiment 5

[0089] Based on any one of the above-mentioned embodiments 2 to 4, this embodiment 5 also adopts the following preferred implementation modes:

[0090] like Figure 2 and Figure 5 As shown, the operating assembly is provided with an operating handle 9, an operating handle rotating pin 10, a gear rotating pin 12 and a gear 13. The operating handle rotating pin 10 and the gear rotating pin 12 are parallel to each other and are both fixed to the upper slide rail 2. The gear 13 is rotatably mounted on the gear rotating pin 12. The middle part of the operating handle 9 is rotatably mounted on the operating handle rotating pin 10. The front end of the operating handle 9 extends to the outside of the upper slide rail 2 for easy operation. The rear end of the operating handle 9 is an arc-shaped toothed end meshing with the gear 13.

[0091] The bottom surface of the front end of the control handle 4 is a linear toothed end 4b meshing with the gear 13;

[0092] Therefore, the rotation of the operating handle 9 can drive the control handle 4 to move in the front-rear direction through the gear 13 .

[0093] Thus, when the front end of the operating handle 9 is lifted, the control handle 4 is driven to move backwards by the roller 7, and when the front end of the operating handle 9 is pressed down, the control handle 4 is driven to move forwards by the roller 7, so that the operating component drives the control handle 4 to move forward and backward. In addition, in the unlocked state, the relative position of the lower slide rail 1 and the upper slide rail 2 can be adjusted by pushing and pulling the operating handle 9.

[0094] Embodiment 6

[0095] On the basis of the above-mentioned embodiment 5, this embodiment 6 also adopts the following preferred implementation manner:

[0096] like Figure 2 , Figure 6-1 and Figure 7-1 As shown, the operating assembly is also provided with an operating handle reset spring 11, which is connected between the operating handle 9 and the upper slide rail 2, and when the roller 7 is located in the locking section 4a1, the operating handle reset spring 11 is in an undeformed state, and when the roller 7 is located in the unlocking section 4a2, the operating handle reset spring 11 is in a deformed state.

[0097] Therefore, when the roller 7 is located in the unlocking section 4a2, that is, when the one-sided locking and unlocking type automobile seat slide rail of the present invention is in the unlocking state, the spring force of the operating handle reset spring 11 can be used to reset the operating handle 9, so that the operating handle 9 drives the control handle 4 to move through the gear 13, so that the roller 7 returns to the locking section 4a1 relative to the control handle 4, thereby realizing the automatic locking of the one-sided locking and unlocking type automobile seat slide rail, and making the locking process of the slide rail more flexible and smooth.

[0098] Preferably, the operating handle reset spring 11 is a torsion spring, which is sleeved on the operating handle rotation pin 10 , and the two ends of the torsion spring are fixedly connected to the operating handle 9 and the upper slide rail 2 , respectively.

[0099] In addition, the operating handle return spring 11 may also be a common compression spring, which is connected between the front end of the operating handle 9 and the upper slide rail 2 .

[0100] Embodiment 7

[0101] On the basis of the above-mentioned embodiment 5, this embodiment 7 also adopts the following preferred implementation manner:

[0102] like Figure 2 , Figure 6-1 and Figure 7-1 As shown, the actuator is also provided with a control handle reset spring 8; the control handle reset spring 8 is connected between the control handle 4 and the upper slide rail 2, and when the roller 7 is located in the locking section 4a1, the control handle reset spring 8 is in the original length state, and when the roller 7 is located in the unlocking section 4a2, the control handle reset spring 8 is in a stretched state.

[0103] Thus, when the roller 7 is located in the unlocking section 4a2, that is, the one-sided locking and unlocking type automobile seat slide rail of the present invention is in the unlocking state, the spring force of the control handle reset spring 8 can be used to reset the control handle 4, so that the roller 7 returns to the locking section 4a1 relative to the control handle 4, thereby realizing the automatic locking of the one-sided locking and unlocking type automobile seat slide rail and making the locking process of the slide rail more flexible and smooth.

[0104] in addition:

[0105] The lower slide rail 1 of the present invention may also be a common equal-height slide rail, or the lower slide rail 1 may also be a high-low rail structure (such as Figure 3 As shown), that is, one of the left and right sides of the lower sliding rail 1 is higher than the other side, and the lower sliding rail 1 uses the higher side as the opening side.

[0106] The lower slide rail 1 and the upper slide rail 2 that slide with each other in the present invention can be any structure in the prior art, and it is generally preferred that: a ball 15 is installed between the upper part of the lower slide rail 1 and the upper part of the upper slide rail 2 through an upper retaining frame 14, and a ball 15 is installed between the lower part of the lower slide rail 1 and the lower part of the upper slide rail 2 through a lower retaining frame 16, so that the mutual sliding fit between the lower slide rail 1 and the upper slide rail 2 is achieved by the rolling action of the ball 15.

[0107] The number of lower rail clamping holes 1a provided on the lower slide rail 1 and the number of upper rail clamping holes 2a provided on the upper slide rail 2 can be freely set according to actual needs, as long as their numbers are greater than the number of clamping teeth 6-1 of the locking card 6.
