[0046] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying 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] In this embodiment, the X direction, Y direction and Z direction are as follows Figure 1 As shown, the X direction is the front-to-back 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 car, the X direction is also the front-to-back direction of the car, the Y direction is also the left-right direction of the car, and the Z direction is the up-down direction of the car. The first direction mentioned in this embodiment is the X direction shown in the figure.

[0049] Please refer to Figures 1 to 4 , Figure 1 This is a structural schematic diagram of a manual slide rail system in an embodiment of the present application; Figure 2 for Figure 1 A front view of the assembly of a manual slide rail system; Figure 3 for Figure 1 Exploded view of the manual slide system; Figure 4 for Figure 2 An exploded view of the middle lock card assembly 32.

[0050] Depend on Figure 2 It can be seen that the manual slide rail system used in the embodiment of the present application includes 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 along a first direction, specifically, the two move along an X direction perpendicular to the Y direction and the Z direction. When applied to a car, the upper slide rail assembly 2 can slide in the front and rear directions relative to the car.

[0051] The locking system 3 includes a locking tooth component 31 and a locking card assembly 32. The locking tooth component 31 in this embodiment is specifically an inverted U-shaped groove structure, and a plurality of first tooth portions 311 distributed along the first direction are arranged on both sides thereof, that is, two rows of first tooth portions 311 are arranged. The locking card assembly 32 includes a locking card 321 (shown in FIG. Figure 4 ), the lock card 321 has a plurality of second teeth 3211 distributed along the first direction. In this embodiment, the lock card 321 is a frame structure, including two side edges arranged opposite to each other along the Y direction, and the plurality of second teeth 3211 are located between the two side edges. Then the lock card 321 in this embodiment is a window structure. Obviously, the lock card 321 can also be provided with only one side edge, in which case the lock card 321 is a comb-type structure. The lock card 321 is provided as a window structure such as a frame-type structure, and the structural strength is more reliable. It can also be easily inserted into the tooth gaps of the plurality of first teeth 311 of the locking tooth component 31, and can ensure that the lock card 321 moves along the Z direction.

[0052] The locking tooth component 31 is fixed to the upper side of the lower slide rail assembly 1 and can be fitted with the surface of the lower slide rail assembly 1; the locking card component 32 is connected to the upper slide rail assembly 2, and the second tooth portion 3211 of the locking card component 32 can be inserted into the tooth gap of the adjacent first tooth portion 311 of the locking tooth component 31. That is, the upper slide rail assembly 2 can achieve relative sliding or locking with the lower slide rail assembly 1 through the movement of the locking card component 32 relative to the locking tooth component 31.

[0053] Please continue to refer to Figures 5 to 7 , Figure 5 for Figure 2 An assembly cross-sectional view of the middle damping system 4 and the locking system 3; Figure 6 for Figure 5 A side view of the middle locking system 3; Figure 7 for Figure 5 A schematic structural diagram of the middle lock window 33.

[0054] The locking assembly 32 can move to a first position and a second position in the Z direction. When the locking assembly 32 is in the first position, that is, the locking assembly 32 is located at the uppermost side (shown in FIG. Figure 6), the second tooth portion 3211 of the locking card assembly 32 and the first tooth portion 311 of the locking tooth component 31 are locked together, that is, the second tooth portion 3211 is located in the tooth gap of the adjacent first tooth portion 311; when the locking card assembly 32 moves downward along the Z direction to be located at the second position, since the length of the first tooth portion 311 of the locking tooth component 31 in the Z direction is shorter, the locking card assembly 32 is separated from the locking tooth component 31 in the Z direction, and the locking card assembly 32 is no longer restricted by the locking tooth component 31, and the locking card assembly 32 and the upper slide rail assembly 2 can move freely along the X direction, then unlocking is achieved, and at this time, manually pulling the upper slide rail assembly 2 can realize 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 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 middle and upper slide rail assembly 2; Fig. 9 for Figure 1 The front view of the middle and upper slide rail assembly 2 is also a cross-sectional view along the Y direction.

[0056] Combination Figure 2 It can be known that the locking system 3 can also include a lock window 33, which is also fixedly connected to the upper slide rail assembly 2. The lock window 33 has a plurality of lock window windows 331 distributed along the first direction, and the lock window windows 331 are equidistantly distributed. Each second tooth portion 3211 of the lock card 321 can be inserted into a corresponding lock window window 331. Among them, the lock window window 331 corresponds to the tooth gap between the two adjacent first tooth portions 311 in the Y direction, and the entity part between the two adjacent lock window windows 331 is defined as the lock window edge 334. The width of the first tooth portion 311 in the X direction is equal to the width of the lock window edge 334, and along the Y direction projection, the projection of the first tooth portion 311 coincides with the projection of the lock window edge 334, and is completely staggered with the projection of the lock window window 331. As shown in FIG. Figure 6 As shown, in the locked state, the second tooth portion 3211 is inserted into the tooth gap between two adjacent second tooth portions 311 and is also located between two adjacent lock window edges 334. In this embodiment, the lock window 33 is provided to strengthen the first tooth portion 311 without interfering with the movement of the lock card assembly 32 in the Z direction to lock or unlock with the locking tooth component 31, and limit the lock card assembly 32 in the lock window window 331, so that it can only move up and down in the Z direction, that is, the second tooth portion 3211 of the lock card 321 is always located in the lock window window 331.

[0057] like Figure 7As shown, the lock window 33 in this embodiment is specifically a U-shaped groove structure, including two lock window side panels 332 extending along the first direction and a lock window bottom panel 333 connecting the two lock window side panels 332, and the lock window window 331 extends from one lock window side panel 332 to the lock window bottom panel 333 and the other lock window side panel 332. As can be seen from the above, the function of the lock window 33 is to limit and strengthen the lock card 321, so the lock window 33 is not limited to the U-shaped groove structure. For example, the lock window 33 is not provided with a lock window bottom panel 333 but is only provided with a comb-shaped structure with a single-sided lock window side panel 332. However, the use of a U-shaped groove structure with a double-sided lock window side panel 332 and a lock window bottom panel 333 as the lock window 33 can further strengthen the structural strength and improve the adjustment accuracy.

[0058] like Figure 5 As shown, part of the locking tooth component 31 is located between the two lock window side plates 332 of the lock window 33, and the first tooth portion 311 of the locking tooth component 31 is not in direct contact with the lock window 33, which can ensure interference-free operation. The lock card assembly 32 can move up and down along the lock window 331, but cannot move relative to the lock window 331 along the X direction, that is, the lock window 33 and the lock card assembly 32 are an assembled whole, and move together with the upper slide rail assembly 2.

[0059] like Figure 4 and Figure 5 As shown, the lock card assembly 32 also includes a push rod 322, a return spring 323 and a lock card fixing seat 324. The push rod 322 is fixedly connected to the lock card 321. The return spring 323 is located between the lock card 321 and the lock card fixing seat 324. The return spring 323 can be specifically limited in position by a riveted column 325, that is, the riveted column 325 is fixed to the lock card 321, and the return spring 323 is sleeved on the outer peripheral side of the riveted column 325. The return spring 323 is elastic and the axis extends along the Z direction, so the return spring 323 can undergo vertical elastic deformation and should always be within the elastic limit. The return spring 323 can provide a return elastic force to push the push rod 322 upward to drive the lock card assembly 32 to lock upward with the locking tooth component 31. That is, the unlocking and locking of the lock card assembly 32 can be achieved by the cooperation of the push rod 322 and the return spring 323. The return spring 323 in this embodiment can be a compression spring or a linear spring.

[0060] Combination Figure 5 and Figure 6 Specifically, when the push rod 322 is not pressed, the return spring 323 provides an upward force to the lock card 321 and the push rod 322, forcing the lock card 321 to be in Figure 6When the push rod 322 is pressed and moved downwardly along the Z direction, the return spring 323 will be compressed until the second tooth portion 3211 of the lock card 321 escapes from the tooth gap of the first tooth portion 311 of the locking tooth component 31 and reaches the second position. Figure 6 The second position shown in the figure is the critical position where the second tooth portion 3211 and the first tooth portion 311 are disengaged. It can be seen that any position at the critical position and below the critical position is the second position. The lock card assembly 32 is unlocked at the second position, 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 portion 3211 of the lock card 321 is still located in a corresponding lock window 331, that is, the lock card assembly 32 can generate relative movement in the X direction relative to the locking tooth component 31, but cannot generate relative movement in the X direction relative to the lock window 33. That is, the lock window 33, the lock card assembly 32 and the upper slide rail assembly 2 move together as a whole. After pressing the push rod 322 to unlock the lock card assembly 32, the upper slide rail assembly 2 can be pulled to slide to the desired position relative to the upper slide rail assembly 1 as needed, and the push rod 322 is released. The lock card 321 of the lock card assembly 32 moves upward under the action of the return spring 323, and the second tooth portion 3211 moves upward to the first position again, and is stuck in the tooth gap between the two adjacent first tooth portions 311, thereby re-locking.

[0061] In addition, if Figure 6 As shown, when re-locking is required, if the first tooth portion 311 is not completely offset from the lock window 331 in the X direction, the second tooth portion 3211 will contact the bottom surface of the first tooth portion 311. At this time, the upper slide rail assembly 1 continues to be pushed, and the second tooth portion 3211 moves with the upper slide rail assembly 1. Under the action of the return spring 323, they can interfere with each other and force the lock card 321 to fine-tune the position along the Y direction, so that the second tooth portion 3211 can automatically slide into the tooth gap between the two adjacent first tooth portions 311 to achieve locking, without the need for manual fine-tuning of the locking.

[0062] Look again Figure 8 and Fig. 9 It can be observed that the upper rail assembly 2 includes an upper rail upper portion 21 and an upper rail lower portion 22. The upper rail upper portion 21 is located above the lower rail assembly 1. The upper rail lower portion 22 includes a first plug-in portion 221 and a second plug-in portion 222. The first plug-in portion 221 can be inserted into the first cavity 1a (shown in FIG. Figure 2 ), the second plug-in portion 222 can be inserted into the second cavity 1b (shown in Figure 2), the first plug-in portion 221 and the second plug-in portion 222 are supported on the lower slide rail assembly 1 by the first roller assembly 231 and the second roller assembly 232. The first roller assembly 231 and the second roller assembly 232 enable the first plug-in portion 221 and the second plug-in portion 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 portion 21 and an upper slide rail lower portion 22. The upper slide rail upper portion 21 can be set to Figure 4 The U-shaped groove structure in the upper slide rail can facilitate fixing small-sized parts such as the armrest box on the upper portion 21 of the upper slide rail, and the lower portion 22 of the upper slide rail is inserted into the lower slide rail assembly 1 to achieve the connection, fixation and limit of the upper slide rail assembly 2 and the lower slide rail assembly 1, ensuring 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 respectively inserted into two different cavities, so that the support sliding is more stable and reliable.

[0063] In addition, the first roller assembly 231 and the second roller assembly 232 have the same structural composition and can be collectively referred to as roller assemblies 23. Each roller assembly 23 includes a roller bearing, a roller bearing shaft and a clamping ring. The first roller assembly 231 and the second roller assembly 232 can be connected to the first plug-in portion 221 and the second plug-in portion 222 respectively and clamped by the clamping ring. The lowest point of the roller surface of the roller bearing fits the inner surface of the lower side of the lower rail assembly 1, that is, fits 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 rail assembly 1. The provision of the roller assembly 23 can reduce friction and ensure that the upper rail assembly 2 slides more smoothly relative to the lower rail assembly 1.

[0064] In this embodiment, the second plug-in portion 222 (shown in Figure 8 , 9 ) includes a top plug-in board 2221 and two opposite side plug-in boards 2222, with an empty slot 222a formed between the top plug-in board 2221 and the side plug-in board 2222. The second plug-in part 222 is in an inverted U shape. Similarly, the first plug-in part 221 can also be set to such a structure or other similar structures that meet the requirements. Here, the second plug-in part 222 is provided with an empty slot 222a, which can conveniently arrange the lock card 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 empty slot 222a is provided to conveniently arrange the damping system 4 and the power supply harness assembly 5. As mentioned above, the lock card assembly 32 and the lock window 33 are both fixed to the upper slide rail assembly 2, specifically, by arranging a lock card fixing seat 324 and a return spring 323 in the empty slot 222a of the second plug-in part 222.

[0065] A side plug-in plate 2222 of the second plug-in portion 222 near the first plug-in portion 221 is further provided with a fixing plate 2223 extending along the first direction, and a lock window bottom plate 333 of the lock window 33 is fixedly connected to the fixing plate 2223. Such a configuration can not only save space, but also ensure that the lock card 321 is always located between the top of the lock window 33 and the fixing plate 2223, ensuring that it moves together as a whole and will not fall out of the lock window 33.

[0066] The second plug-in portion 222 and the upper slide rail upper portion 21 are further provided with a third opening 222b (shown in FIG. 2 ) corresponding to the push rod 322. Figure 8 ), the push rod 322 can pass through the third opening 222b and extend out of the upper surface of the upper slide rail upper portion 21. Obviously, such a structure is more convenient for manually pressing the push rod 322, and the lock card assembly 32 is located inside the lower slide rail assembly 1, which can also play a protective role.

[0067] Please continue to refer to Figure 10 to Figure 11 , Fig.10 for Figure 1 A front view of the middle and lower slide rail assembly 1, which is also a cross-sectional view along the Y direction; Fig.11 for Figure 1 Exploded view of the middle and lower slide rail assembly 1.

[0068] The lower lower rail assembly 1 includes a lower lower rail body 11, and the lower lower rail body 11 has a first cavity 1a and a second cavity 1b. In addition, it also includes a partition wall 14 that separates the first cavity 1a from the second cavity 1b. In order to ensure that the first plug-in portion 221 and the second plug-in portion 222 can be inserted into the first cavity 1a and the second cavity 1b respectively, an opening should be provided on the lower lower rail body 11 for plugging. That is, the top of the lower lower rail body 11 has a first opening 11a corresponding to the first cavity 1a and a second opening 11b corresponding to the second cavity 1b. The first plug-in portion 221 passes through the first opening 11a, and the second plug-in portion 222 passes through the second opening 11b. It can be seen that the first opening 11a and the second opening 11b are both slender openings extending along the X direction. Figure 4 The upper part 21 of the middle upper slide rail is connected to the first plug-in portion 221 through the first strip 26 extending in the X direction, and is connected to the second plug-in portion 222 through another second strip 27 extending in 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 strip in the Y direction, so that the strip is located in the first opening 11a or the second opening 11b and does not interfere with sliding. The strip is provided to connect the corresponding plug-in portion, so that the width of the first opening 11a or the second opening 11b can be minimized, so that the first cavity 1a and the second cavity 1b are roughly closed, and impurities and the like are reduced from falling into the cavity.

[0069] Although the widths of the first opening 11a and the second opening 11b are controlled, after the plugging is completed, the first opening 11a and the second opening 11b will be exposed to the outside. This embodiment can further cover the gaps caused by the openings. Figure 2 , 7 As shown, the lower slide rail assembly 1 also includes a first decorative strip 131 and a second decorative strip 132. The first decorative strip 131 is used to cover the first opening 11a, and the second decorative strip 132 covers the second opening 11b. The first decorative strip 131 and the second decorative strip 132 also have openings extending along the X direction, but the width in the Y direction and the thickness of the first strip 26 and the second strip 27 in the Y direction are roughly equal. The first decorative strip 131 and the second decorative strip 132 can be made of soft materials, such as rubber materials, etc., so that they can have zero contact or small interference fit with the first strip 26 or the second strip 27, thereby ensuring the sealing effect without hindering the sliding of the plug-in part.

[0070] Specifically, a groove can be provided on the lower rail body 11 and a protrusion corresponding to the groove can be provided on the first decorative strip 131 and the second decorative strip 132 to achieve plug-in matching, so as to ensure a tighter fixed cover. Obviously, in addition to plug-in, other connection methods can also be used, such as screw fixing. Figure 7 It can also be seen that a recessed groove is provided on the upper surface of the lower slide rail body 11, and the first decorative strip 131 and the second decorative strip 132 can be embedded in the recessed groove. In this way, after the first decorative strip 131 and the second decorative strip 132 are embedded in the recessed groove, the upper surface of the lower slide rail assembly is flush.

[0071] The upper slide rail assembly 2 in this embodiment also includes a Y-direction clearance eliminating component 24 and a Z-direction clearance eliminating component 25 (wherein the Y and Z directions are already Figure 7 A Y-direction clearance eliminating component 24 and a Z-direction clearance eliminating component 25 are provided between the first plug-in portion 221 and the second plug-in portion 222 and the lower guide rail assembly 1. Figure 4 As shown, the Y-direction clearance elimination component 24 includes a clearance elimination bearing 241, a clearance elimination bearing shaft 242, and a clearance elimination bracket 243. The clearance elimination bearing shaft 241 is inserted into the clearance elimination bearing shaft 242. The clearance elimination bearing shaft 242 is fixedly connected to the clearance elimination bracket 243, and the connection method includes but is not limited to riveting. The clearance elimination bracket 243 is a bent bracket, and its upper surface is fitted with the lower surface of the top plug-in plate 2221. The clearance elimination bracket 243 and the top plug-in plate 2221 can be fixedly connected. The side of the clearance elimination bearing 242 is fitted with the inner surface of the side of the lower slide rail assembly 1, thereby achieving the limit in the Y direction, ensuring that the upper slide rail assembly 2 will not deviate in the Y direction, and the Y-direction clearance can be eliminated after the upper slide rail assembly 2 is installed. The clearance elimination bearing 241 can be assembled with the plug-in part of the upper slide rail assembly 2 and then installed into the lower slide rail assembly 1 together.

[0072] The Z-direction gap elimination component 25 is snap-fitted to the top plug-in plate 2221, and a slot can be set on the top plug-in plate 2221. The Z-direction gap elimination component 2 has a certain deformation ability so as to be snap-fitted into the slot. After the Z-direction gap elimination component 25 is installed on the top plug-in plate 2221, its top is raised, and the upper surface of the Z-direction gap elimination component 25 is fitted with the inner surface of the top of the lower slide rail assembly 1, thereby realizing the limit in the Z direction and ensuring that the upper slide rail assembly 2 will not deviate in the Z direction. After the upper slide rail assembly 2 is installed, the Z-direction gap can be eliminated.

[0073] Please continue to refer to Figure 12 to Figure 13 , Fig.12 for Figure 5 A side view of the middle damping system 4; Fig.13 for Figure 1 Exploded view of the power supply harness assembly 5.

[0074] Combination Figure 2 For illustration, the manual slide rail system in this embodiment further includes a damping system 4, which is located in the first cavity 1a, and a locking system 3 is located in the second cavity 1b. The integrated two-cavity structure can save space while ensuring that the damping system 4 located in the first cavity 1a and the locking system 3 located in the second cavity 1b do not interfere with each other, thereby ensuring the adjustment accuracy.

[0075] like Fig.12 As shown, the damping system 4 includes a rack 41 and a damping unit 42 distributed along a first direction, the rack 41 is fixedly connected to the upper part of the lower slide rail assembly 1, and the damping unit 42 is fixedly connected to the upper slide rail assembly 2. The damping unit 42 is an existing rotary damper. The damping unit 42 includes a circle of damping teeth 421 that can mesh with the rack 41, that is, the damping unit 42 can rotate relative to the rack 41 along with the sliding of the upper slide rail assembly 2. The damping unit 42 can provide damping force when moving in the front-back direction, realize the damping texture of the operation, ensure that the operating speed is relatively stable, and thus enhance the high-level sense and comfort of sliding.

[0076] The manual rail system in this embodiment also includes a power supply harness assembly 5, which is also located in the first cavity 1a to ensure that it does not interfere with the locking system 3. The power supply harness assembly 5 may specifically include a harness 51 and a drag chain 52. The drag chain 52 has a drag chain cavity and a guide groove 52a extending along its length. The harness 51 can be inserted into the drag chain cavity, which can restrain and guide the harness 51. Accordingly, a boss 12 (shown in FIG. 1 ) is provided in the first cavity 1a. Fig. 9), the boss 12 can be inserted into the guide groove 52a to guide and limit the drag chain 52. A hook 521 is also provided at one end of the power supply harness assembly 5, specifically, a hook 521 is provided at one end of the drag chain 52, which can hook the partition wall 14, and the partition wall 14 and the hook 521 are provided with corresponding connection holes, so that one end of the power supply harness assembly 5 can be connected and fixed to the lower slide rail assembly 1, and the other end of the power supply harness assembly 5 is connected to the upper slide rail assembly 2, and the power supply harness assembly 5 is also connected to the harness of the vehicle body at the same time, so as to realize the power supply to the manual slide rail system.

[0077] The manual slide rail system in this embodiment can be applied to automobiles, and the automobiles include an armrest box, and the armrest box needs to be movable, so the manual slide rail system in this embodiment can be used, and the lower rail assembly 1 is installed on the floor of the automobile, and the armrest box is connected to the upper rail assembly 2. The automobile including the manual slide rail system in the above embodiment also has the same technical effect as the above embodiment, and no further description is given.

[0078] It can be understood that the locking tooth component 31 of the locking system 3 and the tooth portion of the locking card assembly 32 of the present embodiment both extend along the first direction (i.e., the X direction), and the locking card 321 of the locking card assembly 32 moves in the vertical direction to achieve locking or unlocking. It can be seen that the locking system 3 is mainly extended along the first direction and moves in the vertical direction, which is convenient for space arrangement, especially for the manual slide rail system of small crotch size components, which often have limited Y-direction space. For example, the Y-direction (left and right direction of the car) space where the armrest box is located is limited, but the Y-direction space and the Z-direction space are relatively larger. The arrangement method in the present embodiment makes the arrangement of the manual slide rail system more convenient.

[0079] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
