[0046] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0047] In the embodiments of the present application, the terms "first" and "second" are mainly used to distinguish the same or similar features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0048] The X direction, Y direction and Z direction in the embodiments are shown in the drawings as follows: Figure 1 The X direction is the front-rear direction of the manual slide rail system, the Y direction is the left-right direction of the manual slide rail system, and the Z direction is the up-down direction of the manual slide rail system. When the manual slide rail system is applied to a vehicle, the X direction is also the front-rear direction of the vehicle, the Y direction is also the left-right direction of the vehicle, and the Z direction is the up-down direction of the vehicle. The first direction mentioned in the embodiments is the X direction shown in the drawings.

[0049] Please refer to Figures 1 to 4 , Figure 1 for the structural schematic diagram of a manual slide rail system in the embodiments of the present application; Figure 2 for Figure 1 the assembly front view of a manual slide rail system in the embodiments of the present application; Figure 3 for Figure 1 the exploded view of a manual slide rail system in the embodiments of the present application;Figure 4 For Figure 2 The exploded view of the lock catch assembly 32.

[0050] By Figure 2 As can be seen, the manual slide rail system used in the embodiments of the present application comprises a lower slide rail assembly 1, an upper slide rail assembly 2 and a locking system 3, wherein the upper slide rail assembly 2 and the lower slide rail assembly 1 are slidably connected in a first direction, specifically, they move in the X direction perpendicular to the Y direction and the Z direction, and when applied to a car, the upper slide rail assembly 2 can slide relative to the front-to-back direction of the car.

[0051] The locking system 3 comprises a locking tooth component 31 and a lock catch assembly 32. The locking tooth component 31 is specifically a reverse U-shaped groove structure in this embodiment, and a plurality of first teeth 311 distributed in the first direction are arranged on both sides thereof, i.e., two rows of first teeth 311 are arranged. Figure 4 The lock catch assembly 32 comprises a lock catch 321 (shown in

[0052] The lock catch 321 has a plurality of second teeth 3211 distributed in the first direction. In this embodiment, the lock catch 321 is in the form of a frame structure, comprising two side edges arranged opposite to each other in the Y direction, and the plurality of second teeth 3211 are located between the two side edges. Therefore, the lock catch 321 in this embodiment is in the form of a window structure. Obviously, the lock catch 321 can also be provided with only one side edge, in which case the lock catch 321 is in the form of a comb structure. The lock catch 321 is arranged in the form of a window structure like a frame structure, which is more reliable in structural strength, can be easily inserted into the tooth gaps of the plurality of first teeth 311 of the locking tooth component 31, and can ensure the movement of the lock catch 321 in the Z direction.

[0053] Please continue to refer to Figures 5 to 7 , Figure 5 For Figure 2 The assembly sectional view of the damping system 4 and the locking system 3; Figure 6 For Figure 5 The matching side view of the locking system 3; Figure 7 For Figure 5 The structural schematic view of the lock window 33.

[0054] The lock catch assembly 32 can move in the Z direction to a first position and a second position. When the lock catch assembly 32 is located at the first position, i.e., the lock catch assembly 32 is located at the uppermost side (shown in Figure 6The second tooth 3211 of the locking assembly 32 engages with the first tooth 311 of the locking tooth component 31 to lock, that is, the second tooth 3211 is located in the gap between the adjacent first teeth 311. When the locking assembly 32 moves downward along Z to the second position, since the first tooth 311 of the locking tooth component 31 is shorter in the Z direction, the locking assembly 32 disengages from the locking tooth component 31 in the Z direction. Then the locking assembly 32 is no longer restricted by the locking tooth component 31, and the locking assembly 32 and the upper slide rail assembly 2 can move freely along the X direction, thus unlocking. At this time, manually pulling the upper slide rail assembly 2 can achieve the sliding of the upper slide rail assembly 2 relative to the lower slide rail assembly 1. That is, the manual slide rail system can be a manual slide rail system, which can be manually unlocked and manually pushed or pulled to slide the upper slide rail assembly 2.

[0055] Please refer to Figures 8 to 9 , Figure 8 for Figure 1 Exploded view of the upper and middle slide rail assembly 2; Figure 9 for Figure 1 The front view of the upper slide rail assembly 2 is also a sectional view along the Y direction.

[0056] Combination Figure 2 It can be seen that the locking system 3 may also include a locking window 33, which is also fixedly connected to the upper slide rail assembly 2. The locking window 33 has multiple locking window openings 331 distributed along the first direction, and the locking window openings 331 are equidistantly distributed. Each second tooth 3211 of the locking clip 321 can be inserted into a corresponding locking window opening 331. The gap between the locking window opening 331 and the tooth of two adjacent first teeth 311 corresponds in the Y direction. The solid portion between two adjacent locking window openings 331 is defined as the locking window ridge 334. The width of the first tooth 311 in the X direction is equal to the width of the locking window ridge 334. Moreover, when projected along the Y direction, the projection of the first tooth 311 coincides with the projection of the locking window ridge 334, and is completely offset from the projection of the locking window opening 331. Figure 6 As shown, in the locked state, the second tooth 3211 is inserted into the gap between two adjacent second teeth 311, and is also located between two adjacent lock window edges 334. In this embodiment, the lock window 33 is provided, which can strengthen the first tooth 311 without interfering with the movement of the locking assembly 32 in the Z direction to lock or unlock with the locking tooth component 31. This limits the locking assembly 32 to be within the lock window 331, and it can only move up and down in the Z direction. That is, the second tooth 3211 of the locking 321 is always located within the lock window 331.

[0057] like Figure 7As shown, the lock window 33 in the embodiment is specifically a U-shaped groove structure, including two lock window side plates 332 extending along the first direction and a lock window bottom plate 333 connecting the two lock window side plates 332, and the lock window window 331 extends from one lock window side plate 332 to the lock window bottom plate 333 and the other lock window side plate 332. As known from the foregoing, the lock window 33 functions to position and strengthen the lock catch 321, and therefore the lock window 33 is not limited to be a U-shaped groove structure, for example, the lock window 33 is not provided with the lock window bottom plate 333 but only provided with a comb-shaped structure with a single lock window side plate 332, which can also achieve the purpose, but the U-shaped groove structure with the double lock window side plates 332 and the lock window bottom plate 333 as the lock window 33 can further strengthen the structural strength and improve the adjustment accuracy.

[0058] As shown in Figure 5 , part of the lock tooth component 31 is located between the two lock window side plates 332 of the lock window 33, and the first tooth part 311 of the lock tooth component 31 does not directly contact the lock window 33, which can ensure that the operation is not disturbed. The lock catch assembly 32 can move up and down along the lock window window 331, and cannot have relative movement along the X direction relative to the lock window window 331, that is, the lock window 33 and the lock catch assembly 32 are an assembly as a whole, and move together with the upper slide rail assembly 2.

[0059] As shown in Figure 4 and Figure 5 , the lock catch assembly 32 further includes a push rod 322, a reset spring 323 and a lock catch fixing seat 324, the push rod 322 and the lock catch 321 are fixedly connected, and the reset spring 323 is located between the lock catch 321 and the lock catch fixing seat 324. The reset spring 323 can be positionally limited by a riveting column 325, that is, the riveting column 325 is fixed to the lock catch 321, and the reset spring 323 is sleeved on the outer circumferential side of the riveting column 325. The reset spring 323 has elasticity and an axis extending along the Z direction, so that the reset spring 323 can have vertical elastic deformation and should always be within the elastic limit, and the reset spring 323 can provide a reset elastic force to push the push rod 322 upward to drive the lock catch assembly 32 upward to lock with the lock tooth component 31. That is, the unlocking and locking of the lock catch assembly 32 can be realized by the cooperation of the push rod 322 and the reset spring 323. The reset spring 323 in the embodiment can be a compression spring or a linear spring.

[0060] In combination with Figure 5 and Figure 6 , specifically, when the push rod 322 is not pressed, the reset spring 323 provides an upward force to the lock catch 321 and the push rod 322, which will force the lock catch 321 to be in Figure 6The first position shown, the second tooth part 3211 and the first tooth part 311 are locked together, so that the upper slide rail assembly 2 and the lower slide rail assembly 1 can be locked; when the push rod 322 is pressed and moved downward along the Z direction, the reset spring 323 will be compressed until the second tooth part 3211 of the locking catch 321 is out of the tooth gap of the first tooth part 311 of the locking tooth part 31, reaching the second position, Figure 6 The second position shown in the middle is the critical position where the second tooth part 3211 and the first tooth part 311 are disengaged. It can be seen that at this critical position and any position below the critical position, it is the second position, and at the second position, the locking catch assembly 32 is unlocked, and the upper slide rail assembly 2 and the lower slide rail assembly 1 can slide relative to each other. In the second position, the second tooth part 3211 of the locking catch 321 is still located in the corresponding one of the locking window windows 331, that is, the locking catch assembly 32 can produce relative movement in the X direction relative to the locking tooth part 31 at this time, but cannot produce relative movement in the X direction relative to the locking window 33. That is, the locking window 33, the locking catch assembly 32, and the upper slide rail assembly 2 move as a whole. After the push rod 322 is pressed to unlock the locking catch assembly 32, the upper slide rail assembly 2 can be pulled relative to the lower slide rail assembly 1 to the desired position as needed, and the push rod 322 is released. The locking catch 321 of the locking catch assembly 32 moves upward under the action of the reset spring 323, the second tooth part 3211 moves upward to the first position again, and is clamped into the tooth gap between the two adjacent first tooth parts 311 to re-lock.

[0061] In addition, as Figure 6 shown, when re-locking is needed, if the first tooth part 311 is not completely misaligned with the locking window window 331 in the X direction, the second tooth part 3211 will contact the bottom surface of the first tooth part 311. At this time, continue to push the upper slide rail assembly 1, the second tooth part 3211 moves with the upper slide rail assembly 1, and under the action of the reset spring 323, the locking catch 321 can interfere with each other to adjust the position along the Y direction, so that the second tooth part 3211 can automatically slide into the tooth gap between the two adjacent first tooth parts 311 to achieve locking, without the need for manual adjustment.

[0062] Looking at Figure 8 and Figure 9 , it can be observed that the upper slide rail assembly 2 includes an upper slide rail upper part 21 and an upper slide rail lower part 22, and the upper slide rail upper part 21 is located above the lower slide rail assembly 1. The upper slide rail lower part 22 includes a first plug-in part 221 and a second plug-in part 222, the first plug-in part 221 can be inserted into the first cavity 1a (shown in Figure 2 ), and the second plug-in part 222 can be inserted into the second cavity 1b (shown in Figure 2), the first plug-in part 221 and the second plug-in part 222 are supported by the first roller assembly 231 and the second roller assembly 232 on the lower slide rail assembly 1, and the first roller assembly 231 and the second roller assembly 232 enable the first plug-in part 221 and the second plug-in part 222 to move more smoothly relative to the lower slide rail assembly 1. In detail, the upper slide rail assembly 21 is divided into an upper slide rail upper part 21 and an upper slide rail lower part 22, the upper slide rail upper part 21 can be provided with a U-shaped groove structure in the upper slide rail assembly 2 Figure 4 , so that small-sized parts such as armrest boxes can be fixed on the upper slide rail upper part 21, the upper slide rail lower part 22 is inserted into the lower slide rail assembly 1 to realize the connection, fixation and limiting of the upper slide rail assembly 2 and the lower slide rail assembly 1, and to ensure that the upper slide rail assembly 2 can reciprocate along the lower slide rail assembly 1, and the lower slide rail assembly 1 includes plug-in parts inserted into two different cavities respectively to support the sliding to be more stable and reliable.

[0063] In addition, the first roller assembly 231 and the second roller assembly 232 have the same structure and can be collectively referred to as a roller assembly 23, each roller assembly 23 includes a roller bearing, a roller bearing shaft and a collar. The first roller assembly 231 and the second roller assembly 232 can be connected to the first plug-in part 221 and the second plug-in part 222 respectively and clamped by the collar. The lowest point of the roller surface of the roller bearing is attached to the inner surface of the lower side of the lower slide rail assembly 1, i.e. attached to the bottom wall corresponding to the first cavity 1a or the second cavity 1b, that is, the roller assembly 23 is supported on the lower slide rail assembly 1, and the arrangement of the roller assembly 23 can reduce friction and ensure that the upper slide rail assembly 2 slides more smoothly relative to the lower slide rail assembly 1.

[0064] In this embodiment, the second plug-in part 222 (shown in Figure 8 , 9 ) includes a top plug-in plate 2221 and two opposite side plug-in plates 2222, and an empty groove 222a is formed between the top plug-in plate 2221 and the side plug-in plate 2222, and the second plug-in part 222 is in an inverted U shape. Similarly, the first plug-in part 221 can also be provided with such a structure or other similar structures that meet the requirements. Here, the second plug-in part 222 is provided with the empty groove 222a to facilitate the arrangement of the locking assembly 32 in the second cavity 1b to maximize the use of the space of the second cavity 1b; correspondingly, for the first plug-in part 221, the arrangement of the empty groove 222a facilitates the arrangement of the damping system 4 and the power harness assembly 5. As described above, the locking assembly 32 and the locking window 33 are both fixed on the upper slide rail assembly 2, specifically by arranging a locking fixing seat 324 and a return spring 323 in the empty groove 222a of the second plug-in part 222.

[0065] The second inserting part 222 is provided with a fixing plate 2223 extending along the first direction at one side of the second inserting part 222, and the lock window bottom plate 333 of the lock window 33 is fixedly connected with the fixing plate 2223. In this way, not only the space is saved, but also the lock catch 321 is always located between the top of the lock window 33 and the fixing plate 2223, so that the lock catch 321 is guaranteed to move as a whole and cannot be separated from the lock window 33.

[0066] The second inserting part 222 and the upper slide rail upper part 21 are further provided with a third opening 222b (shown in Figure 8 ) corresponding to the push rod 322, and the push rod 322 can extend out of the upper surface of the upper slide rail upper part 21 through the third opening 222b. Obviously, in this way, the push rod 322 is more convenient to press manually, and the lock catch assembly 32 is located in the interior of the lower slide rail assembly 1, so that the lock catch assembly 32 is protected.

[0067] Please continue to refer to Figures 10 to 11 , Figure 10 for Figure 1 the front view of the lower slide rail assembly 1, which is also a sectional view along the Y direction; Figure 11 for Figure 1 the exploded view of the lower slide rail assembly 1.

[0068] The lower slide rail assembly 1 comprises a lower slide rail body 11, and the lower slide rail body 11 is provided with a first cavity 1a and a second cavity 1b, and further comprises a partition wall 14 separating the first cavity 1a and the second cavity 1b. In order to guarantee that the first inserting part 221 and the second inserting part 222 can be respectively inserted into the first cavity 1a and the second cavity 1b, the lower slide rail body 11 should be provided with openings for insertion. That is, the top of the lower slide rail body 11 is provided with a first opening 11a corresponding to the first cavity 1a and a second opening 11b corresponding to the second cavity 1b, the first inserting part 221 passes through the first opening 11a, and the second inserting part 222 passes through the second opening 11b. It can be known that the first opening 11a and the second opening 11b are both elongated openings extending along the X direction, Figure 4 The upper slide rail upper part 21 is connected with the first inserting part 221 through a first long strip 26 extending along the X direction and is connected with the second inserting part 222 through another second long strip 27 extending along the X direction. The width of the first opening 11a or the second opening 11b in the Y direction is greater than the thickness of the long strip in the Y direction, so that the long strip is located in the first opening 11a or the second opening 11b and does not interfere with the sliding. The long strip is arranged to connect the corresponding inserting part, so that the width of the first opening 11a or the second opening 11b can be reduced as much as possible, the first cavity 1a and the second cavity 1b are substantially closed, and the falling of impurities into the cavities is reduced.

[0069] Although the width of the first opening 11a and the second opening 11b is controlled, the first opening 11a and the second opening 11b are exposed after the plug-in is completed. The embodiment can further cover the gap caused by the opening. As shown in Figure 2 , 7 The lower slide rail assembly 1 further includes a first decorative strip 131 and a second decorative strip 132.
