Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and in particular to a manual slide rail assembly of an automobile armrest box. Background Art

[0002] The armrest is a car accessory located in the back between the driver and front passenger seats. It primarily provides elbow support for the driver and passenger, allowing them to rest their arms effectively. It also serves as a storage space for small items like drinks and cups.

[0003] With the development of technology and the continuous upgrading of automobiles, especially new energy vehicles, people's pursuit of comfort is becoming increasingly higher. In addition to cup holders and storage functions, armrests are gradually integrating high-tech features such as wireless charging, onboard refrigerators, and human-computer interactive touch screens. Since the driver and passenger seats can move forward and backward, the armrests also need to be able to move forward and backward to align with the driver's seat.

[0004] Traditional armrests primarily rely on the rotation of a handle to translate into horizontal movement of the armrest along a slide rail assembly. To maximize interior space, current vehicles, especially new energy vehicles, often feature longer slide rails for the driver and front passenger seats, increasing travel. This, in turn, places higher demands on armrest travel. However, due to the constraints of the coordination and spatial relationships between the various moving components, the lubrication of the slide rail grooves, and the stability of the armrest during movement, the manual slide rail assemblies of traditional automotive armrests no longer meet these requirements. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the prior art, the utility model provides a manually operated slide rail assembly which can realize the sliding locking of a vehicle armrest box over a long travel.

[0006] The locking mechanism is configured to lock the vehicle body by a locking mechanism, wherein the locking mechanism comprises a locking groove seat connected to the inner slide rail and an unlocking lever pivotally connected to the lock groove seat through a pull rod support block and a pivot. The unlocking lever has a wire hole at one end thereof for connecting the wire, and a pressure rod is provided at the lower side of the other end thereof. A return spring is provided on the pressure rod outer sleeve, and the pressure rod is located above the inner slide rail, and a supporting plate is provided at the bottom of the pressure rod to limit the return spring. A locking plate is provided in the lock groove seat, and a locking claw is provided at the edge of the locking plate for locking with the locking groove.

[0007] Furthermore, the unlocking rod is parallel to the lock slot seat and the inner slide rail, the multiple locking openings are arranged on the left and right sides of the outer slide rail, and locking claws are arranged at both ends of the locking plate, thereby forming a bilateral locking structure.

[0008] Furthermore, the unlocking pull rod is perpendicular to the lock slot seat and the inner slide rail, the multiple locking openings are arranged on one side of the outer slide rail, and the corresponding ends of the locking plates are each provided with a locking claw, thereby forming a unilateral locking structure.

[0009] The manual slide rail assembly of the automobile armrest box has guide cavities with top slots symmetrically arranged on the left and right sides of the outer slide rail, and a rolling track extending along the length direction and supporting the roller is arranged on the outer side of the bottom of the guide cavity.

[0010] The manual slide rail assembly of the automobile armrest box, the outer slide rail also includes a mounting cavity arranged between the two guide cavities, and the locking opening is arranged at the top end of the left and right side walls of one or both mounting cavities.

[0011] The manual slide rail assembly of the automobile armrest box has a lock slot seat with a U-shaped cross section, formed by bending a single metal plate, and one or two side walls of the lock slot seat are provided with a notch for the lock claw to pass through.

[0012] The manual slide rail assembly of the automobile armrest box is formed by connecting the top plate and the left and right side plates. The top plate is provided with a card interface for accommodating the locking mechanism. For the bilateral locking structure, the card interface is set in the center of the top plate. For the unilateral locking structure, the card interface is set at the edge of the top plate. A card interface is also set on the side plate. The two card interfaces are connected, and the roller is installed on the side plate through the wheel axle.

[0013] The manual slide rail assembly of the automobile armrest box has a roller that is a ball bearing. Auxiliary rollers are arranged side by side on the side panels, located in front of or behind the rollers and used to adjust the upper and lower gaps between the inner and outer slide rails.

[0014] The beneficial effects of the utility model are:

[0015] The inner rail cannot move forward and backward along the outer rail, thus realizing precise locking of the inner rail on the outer rail, and is not limited by the length of the rail.

[0016] The utility model can push the armrest box forward / backward on the slide rail assembly by manually pulling the pull wire. The minimum movement distance is the minimum spacing between the two locking openings on the outer slide rail. The texture effect and accuracy of the entire control process are better. The manual switch can be set anywhere on the armrest box, which greatly improves the human-machine space experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1 、 Figure 2 As shown, the utility model discloses a manual sliding locking mechanism for a car armrest box, comprising an outer slide rail 1 fixedly connected to the vehicle body and an inner slide rail 2 that carries the armrest box and is fastened to the armrest box, the outer slide rail 1 being provided with a locking opening 14, the outer slide rail 1 being provided with a roller 25 connected to the inner slide rail 2, the inner slide rail 2 being provided with a locking mechanism 3 and a wiring harness connector 4, the wiring harness connector 4 being used to lead out the relevant wiring harness 5.

[0027] Reference Figure 3 、 Figure 4 As shown, the inner slide rail 2 is formed by connecting a top plate 21 and two left and right side plates 22. The top plate 21 is provided with a card interface 26 for accommodating the locking mechanism 3. For the bilateral locking structure, the card interface 26 is set at the center of the top plate 21. For the unilateral locking structure, the card interface 26 is set at the edge of the top plate 21, and a card interface 26 is also set on the side plate 22. The two card interfaces 26 are connected. The roller 25 is installed on the side plate 22 through the wheel axle 23. The roller 25 is a ball bearing. The side plate 22 is also provided with auxiliary rollers 24 located in front of or behind the roller 25 for adjusting the upper and lower gaps between the inner slide rail 2 and the outer slide rail 1. The outer slide rail 1 is symmetrically provided with guide cavities 11 with top grooves on the left and right sides. The outer side of the bottom of the guide cavity 11 is provided with a raceway 13 extending along the length direction and supporting the roller 25. The outer slide rail 1 also includes an installation cavity 12 arranged between the two guide cavities 11, and the locking port 14 is arranged at the top of the left and right side walls of one or two installation cavities 12.

[0028] Reference Figure 5 、 Figure 6 and Figure 7 As shown, the locking mechanism 3 includes a lock slot seat 31 connected to the inner slide rail 2 and an unlocking pull rod 32 pivotally connected to the lock slot seat 31 through a pull rod support block and a pivot. A pull wire hole 33 is provided at one end of the unlocking pull rod 32 for connecting the pull wire, and a pressure rod 34 is provided on the lower side of the other end. A reset spring 35 is provided on the outer sleeve of the pressure rod 34. The pressure rod 34 is located above the inner slide rail 2, and a support plate 36 is provided at the bottom end of the pressure rod 34 for limiting the reset spring 35. A locking plate 37 is provided in the lock slot seat 31, and a locking claw 38 is provided on the edge of the locking plate 37, which is staggered with the locking mouth 14 for locking.

[0029] In the initial state, the outer slide rail 1 limits the locking claw 38 on the locking mechanism 3 through the locking hole 14, and the inner slide rail 2 cannot move forward and backward along the outer slide rail 1. Once the pull wire connected to the pull wire hole 33 is pulled, the unlocking pull rod 32 rotates around the lock groove seat 31, and the end of the unlocking pull rod 32 presses the pressure rod 34 downward, and the pressure rod 34 drives the locking plate 37 downward. At the same time, the return spring 35 is compressed and stored between the top pressure piece and the bottom support plate 36. After the locking plate 37 moves downward, it drives the locking claw 38 to move downward along the notch 39 and disengage from the lock groove seat 31. At the same time, it is separated from the staggered locking openings 14, and the inner slide rail 2 is released from the outer slide rail 1. It moves back and forth along the outer slide rail 1 through the roller 25, realizing a long-stroke movement of the armrest box in the vehicle body. Once the pull wire stops pulling, the unlocking rod 32 drives the locking plate 37 upward under the action of the return spring 35, and the locking claw 38 is driven to move upward to the locking opening 14 and is staggered again. The inner slide rail 2 cannot move back and forth along the outer slide rail 1, realizing the precise locking of the inner slide rail 2 on the outer slide rail 1, and is not limited by the length of the slide rail.

[0030] The unlocking pull rod 32 of the present invention is parallel to the lock slot seat 31 and the inner slide rail 2, the multiple locking openings 14 are arranged on the left and right sides of the outer slide rail 1, and the locking claws 38 are provided at both ends of the locking plate 37, thereby forming a bilateral locking structure.

[0031] The unlocking pull rod 32 of the present invention is perpendicular to the lock slot seat 31 and the inner slide rail 2, the multiple locking openings 14 are arranged on one side of the outer slide rail 1, and the locking plate 37 is provided with a locking claw 38 at one corresponding end, thereby forming a unilateral locking structure.

[0032] This embodiment selects a unilateral locking structure, which makes the assembly simpler in structure and has a lower failure rate while ensuring complete functionality.

[0033] Furthermore, the lock slot seat 31 has a U-shaped cross-section and is formed by bending a single metal plate. One or both side walls of the lock slot seat 31 are provided with a notch 39 for the lock claw 38 to pass through.

[0034] The utility model can push the armrest box forward / backward on the slide rail assembly by manually pulling the pull wire. The minimum movement distance is the minimum spacing between the two locking openings 14 on the outer slide rail 1. The texture effect and accuracy of the entire operation process are better. The manual switch can be set anywhere on the driver and co-pilot seats, which greatly improves the human-machine space experience.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some embodiments of its application. A person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
