[0054] The following further detailed description of the present utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the specification.

[0055] Such as Figures 1-11As shown in the figure, the present utility model provides a manual slide rail for an automobile, which mainly includes: a lower slide rail 110, a lower slide rail 120, a locking structure 130, a lower roller 140, an upper roller 150, a slider 160 and a tensioning mechanism 170.

[0056] The lower slide rail 110 has a long strip-shaped housing and is fixedly connected to the automobile body. The upper slide rail 120 is arranged parallel to the upper side of the lower slide rail 110 and can move along the length direction of the lower slide rail 110 or be fixed on the lower slide rail 110 through the locking structure 130.

[0057] The locking structure 130 mainly includes: a locking structure bracket 131, an unlocking slide 132, a locking pin 133, a locking pin return spring 134, an unlocking cable 135 and a slide return spring 136.

[0058] The locking structure bracket 131 is fixedly installed on the lower side of the upper slide rail 120 and is arranged inside the lower slide rail 110 (housing); a plurality of first through holes 131a are formed on the locking structure bracket 131; the first through holes 131a are arranged along the width direction of the lower slide rail 110, and a plurality of first through holes 131a are arranged at intervals along the length direction of the lower slide rail 110. Among them, a plurality of locking holes 111 are formed on the side wall of the lower slide rail 110 (housing), and the locking holes 111 are arranged at intervals along the length direction of the lower slide rail 110; and one side of the locking structure bracket 131 is closely attached to the inner wall of the lower slide rail 110 (housing), and during the process of the locking structure bracket 131 moving along the length direction of the lower slide rail 110, a plurality of first through holes 131a can be in one-to-one correspondence and communication with different locking holes 111.

[0059] The unlocking slide 132 is arranged closely attached to the side of the locking structure bracket 131 facing away from the locking hole. A plurality of second through holes 132a are formed on the unlocking slide 132, and the second through holes 132a are arranged in one-to-one correspondence with the first through holes 131a.

[0060] One ends of a plurality of locking pins 133 pass through the second through holes 132a and are inserted into the first through holes 131a one by one, and the locking pins 133 can move axially along the first through holes 131a. Among them, the second through holes 132a are waist-shaped holes, the length direction of the second through holes 132a is arranged along the length direction of the lower slide rail 110, and the length of the second through holes 132a is greater than the aperture of the first through holes 131a, so that the unlocking slide 132 can move along the length direction of the lower slide rail 110.

[0061] One end of each of a plurality of lock pin return springs 134 is connected to the other end of the lock pin 133 in a one-to-one correspondence and abuts against the unlocking slide 132. The outer diameter of the lock pin return spring 134 is larger than that of the second through hole 132a and cannot pass through the second through hole 132a. Wherein, an extension part 137 is connected to the side of the locking structure close to the unlocking slide 132. The extension part 137 bypasses the unlocking slide 132 from the bottom of the unlocking slide 132 without affecting the sliding of the unlocking slide 132. The other end of the lock pin return spring 134 is fixed in the extension part 137 of the locking structure bracket.

[0062] One end of the unlocking wire 135 is connected to one end of the unlocking slide 132, and the other end extends above the upper slide rail 120 for the user to pull.

[0063] One end of the slide return spring 136 is connected to the end of the unlocking slide 132 where the unlocking wire 135 is connected, and the other end is connected to the extension part 137 of the locking structure bracket near the end of the unlocking wire 135. Wherein, the unlocking slide 132 is provided with a recess 132b at each position near its two ends, and the locking structure bracket 131 is provided with two protruding parts 131b, and the protruding parts 131b correspond to the recesses 132b one by one; the recess 132b is a slope on the side facing away from the unlocking wire 135.

[0064] In the locked state, the protruding part 131b is located in the recess 132b, and the lock pin 133 is inserted into the lock hole 111. By pulling the unlocking wire 135, the unlocking slide 132 can be pulled to move along the length direction of the lower slide rail 110, so that the protruding part 131b moves along the slope to the top of the unlocking slide 132 (the side close to the locking structure bracket 131), so that the unlocking slide 132 moves towards the lock pin return spring 134, compresses the unlocking return spring 134, and drives the lock pin 133 to move out of the lock hole 111 to achieve unlocking.

[0065] As a preference, the size of the lock hole 111 in the length direction of the lower slide rail 110 is larger than the aperture of the first through hole 131a, so that the lock pin 133 can smoothly enter or exit the lock hole 111.

[0066] When the unlocking wire 135 is pulled, the unlocking slide 135 is stressed towards the wire side. Under the action of the two protruding parts 131b, a downward component force is generated, so as to overcome the force of the lock pin return spring 134, pull the lock pin 133, and generate a contraction movement.

[0067] The unlocking force is related to the inclined plane angle of the unlocking sliding piece 132. By varying the angle at the contact points with the two protruding parts 131b of the lower bracket of the lock structure, a gradient unlocking operating force can be designed. The unlocking process needs to overcome the forces of multiple lock pin return springs 134 and the sliding piece return tension spring 136, resulting in a relatively large operating force. After complete unlocking, only the force of the sliding piece return spring 136 needs to be overcome to maintain the unlocked state, and the required operating force is smaller. The gradient operating force during unlocking can provide a clearer perception of the unlocking operation.

[0068] The lock structure bracket 131 and the unlocking sliding piece 132 are thin-walled structures with uniform wall thickness. The thickness of the lock structure bracket 131 is 2.0 - 4.0, and the thickness of the unlocking sliding piece 132 is 1.0 - 2.0. The lock pin 133 is mainly cylindrical as a whole, and a ring structure is provided at one end for installing the lock pin return spring 134. The lock structure bracket 131 and the unlocking sliding piece 131 of the lock structure 130 are preferably made of steel plate materials and manufactured by stamping process. It can also be manufactured by die casting combined with machining to improve the local dimensional accuracy and reduce the product weight. The lock pin 133 can be turned after cold heading to obtain better dimensional accuracy while maintaining a low manufacturing cost. When the dimensional accuracy requirements are low, it can also be directly formed by cold heading process.

[0069] The lock pin 133 of the lock structure 130 can be inserted into the lock hole 111 of the lower slide rail 110 to play a locking role. By pulling the unlocking cable 135, the lock pin 133 can be contracted into the interior of the lock structure bracket 131 and pulled out from the lock hole 111 of the lower slide rail 110. After unlocking, the upper slide rail 120 can slide.

[0070] In this embodiment, the lower slide rail 110 (housing) is divided into two chambers in the width direction; two strip-shaped openings 112 penetrating the length direction of the housing are spaced apart on the top plate of the housing, and the strip-shaped openings 112 communicate with the two chambers one by one. Two mounting brackets 121 are provided on the lower side of the upper slide rail 120, and the mounting brackets 121 extend into the two chambers through the two strip-shaped openings 112 one by one. Among them, the lock structure 130 is installed on one mounting bracket 121.

[0071] A lower roller 140 is installed at each end of the mounting bracket 121. The lower roller 140 contacts the upper surface of the bottom plate of the lower slide rail 110 (housing) and can roll along the length direction of the lower slide rail 110. Among them, the lower rollers 140 on the two mounting brackets 121 are respectively arranged close to the two side plates on the width direction side of the lower slide rail 110 (housing).

[0072] In one embodiment, upper rollers 150 are respectively installed at both ends of the mounting bracket 121. The upper rollers 150 are installed on the mounting bracket 121 through a tensioning device 170, so that the upper rollers 140 press against the lower surface of the top plate of the lower slide rail 110 (housing). By providing the upper rollers 140, a damping force can be provided for the sliding of the upper guide rail 120.

[0073] In one embodiment, the upper rollers 150 are replaced with sliders 160. That is, sliders 160 are respectively installed at both ends of the mounting bracket 121. The sliders 160 are installed on the mounting bracket 121 through a tensioning device 170, so that the sliders 160 press against the lower surface of the top plate of the lower slide rail 110 (housing). The friction between the sliders 160 and the top plate of the lower slide rail 110 provides a damping force for the sliding of the upper guide rail 120.

[0074] The slider 160 can be a plastic slider. By replacing the upper roller 150 with a plastic slider and making friction contact with the lower surface of the top plate of the lower slide rail 110 (housing), a certain frictional resistance can be generated. The pressing force between the slider and the slide rail can be adjusted through the tensioning device 170, so as to adjust the sliding resistance and realize the operation force allocation of the manual slide rail. After the slider 160 is worn during long-term operation, it can also continuously maintain the pressing effect under the action of the tensioning device 170, and the sliding resistance is stable and reliable. The 160 slider can be directly integrally injection-molded from plastic material, or can be injection-molded in combination with metal inserts to improve the strength of the part. Using plastic sliders instead of metal rollers can also reduce the manufacturing cost of the product.

[0075] In this embodiment, an upper roller 150 is installed at one end of the mounting bracket 121, and a slider 160 is installed at the other end; sliding guidance and rolling guidance can be achieved simultaneously.

[0076] In this embodiment, the tensioning device 170 includes: a tensioning torsion spring 171, one end of which abuts against the bottom of the mounting bracket 121; a tensioning bracket 172, which is arranged at the bottom of the mounting bracket 121, and the other end of the tensioning torsion spring 171 abuts against the tensioning bracket 172, and the abutting position of the tensioning torsion spring 171 is close to one end of the tensioning bracket 172. Among them, the tensioning torsion spring 171 and the tensioning bracket 172 are connected to the mounting bracket 121 through the same pin shaft 173, and the tensioning bracket 172 can rotate around the pin shaft 173; the upper roller 150 (or slider 160) is rotatably connected to the other end of the tensioning bracket 172 through an upper roller shaft 151 (or shaft 161). One end of the tensioning torsion spring 171 presses against the mounting bracket 121 of the upper slide rail 110, and the other end presses against the roller bracket 172. Through the lever action, an upward tensioning force is exerted on the upper roller 150 (or slider 160) to keep the upper roller 150 (or slider 160) pressing against the top of the lower slide rail 110 (housing).

[0077] As a preference, roller scrapers 141 are respectively installed on the front and rear sides of the lower pulley 140 to sweep the sundries in the lower track 110 and prevent the influence on the rolling of the lower pulley 140.

[0078] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
