Description

Technical Field

[0001] The invention relates to the technical field of automobile interior accessories, and in particular to a pop-up armrest composite flip mechanism. Background Art

[0002] The car armrest box is a car accessory installed between two seats, belonging to the car interior system. Its humanized design was originally intended to allow car drivers to place their arms when driving for a long time, so that their arms can get an effective rest without numbness or stiffness. With the continuous development of manufacturing technology and the continuous improvement of production processes, the armrest box has an additional storage function, such as storing small items such as drinks and cups, so that the driver can easily get these small items when needed.

[0003] At present, the armrest covers of most cars are hinged to the box body by a hinge. There are two main hinge structures used in the armrest box: one is to use only a spring. After opening, the armrest cover automatically pops up to the end position (for example, 90 degrees) and stops, and then the armrest cover can only be closed by hand. With this structure of hinge, the rebound phenomenon during the opening of the armrest cover may injure the rear seat occupants of the car; the other is to hold the armrest cover by hand after opening, without any supporting force, and the armrest cover will automatically fall down when released. With this structure, it cannot be operated with one hand, lacks convenience and safety.

[0004] The publication number is CN222025618U, and the patent name is a Chinese utility model patent for a self-opening suspension hinge structure. It discloses a self-opening suspension hinge structure, including a fixed bracket and a rotating bracket; the shaft pin passes through the mounting surfaces of the fixed bracket and the rotating bracket, and is symmetrically arranged on both sides, one side of the auxiliary spring is fixed on the shaft pin, and the other side passes through the self-starting limit hole on the mounting surface of the rotating bracket; the damping component is sleeved on the shaft pin to limit the mounting surfaces of the fixed bracket and the rotating bracket, and the damping component includes a metal gasket, a first friction plate, a second friction plate, and a metal spring arranged from the outside to the inside; the auxiliary spring has an initial torque, which limits the rotation angle of the rotating bracket to 10-18°. It not only realizes the self-opening of the rotating bracket, but also realizes the real-time suspension of the rotating bracket. The overall structure is simple, practical, and easy to produce and install.

[0005] In the prior art, self-opening and hovering are achieved through the cooperation of springs and transition pieces. When the spring fails, the entire mechanism cannot work, which increases maintenance costs, limits the opening angle, and affects the use of the driver and passengers. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a pop-up handrail composite flipping mechanism which omits a transition piece and does not affect the use even after the elastic piece fails.

[0010] In the above technical solution, the pull rod assembly installation position includes a notch structure symmetrically arranged on the rotating connection portion, with an open front end and a blocking protrusion, and a tension spring fixing position located on the horizontal working surface of the lower sheet metal body.

[0011] In the above technical solution, the pull rod includes a long pull rod, and the elastic member includes a first tension spring and a second tension spring. The two working ends of the long pull rod can be movably passed through the slot structure and cooperate with the linkage matching position to keep the long pull rod parallel to the horizontal working surface of the lower sheet metal body. The working ends of the first tension spring and the second tension spring are both mounted on the long pull rod, and the connecting ends of the first torsion spring and the second torsion spring are connected to the tension spring fixing position, so that the first tension spring and the second tension spring are located in the space formed by the horizontal working surface of the lower sheet metal body and the long pull rod.

[0012] In the above technical solution, the installation position of the pull rod assembly is formed by symmetrically folding the two extended ends of the rotating connection part, and movable holes are provided on the folded surfaces and are arranged opposite to the working surface of the linkage matching position.

[0013] In the above technical solution, the pull rod includes two short pull rods arranged parallel to each other and respectively inserted into the movable holes. The elastic member is a compression spring sleeved on the short pull rod. The front end of the short pull rod extends out from the movable hole and is limited by the stop member, so that there is a travel gap between the inner end surface of the stop member and the working surface of the pull rod assembly installation position. The compression spring is located between the pull rod assembly installation position and the linkage matching position, so that the rear working end of the short pull rod is against the working surface of the linkage matching position.

The friction member includes a plurality of shaft sleeves which are sleeved on the shaft pin and are located between the upper sheet metal member and the lower sheet metal member and at the outer working surface of the upper sheet metal member.

[0016] In the above technical solution, one of the shaft sleeves is located at the partition member installation position to maintain a spatial partition between the upper sheet metal member and the lower sheet metal member.

[0017] Compared with the prior art, the present invention has the following beneficial effects: by cooperating the pull rod with the spring to directly act on the upper sheet metal, the upper sheet metal can realize the opening action, and can simultaneously control its opening angle and the consistency of the opening action, eliminating the auxiliary restriction of the opening angle by the transition piece, and has a simple structure, which is beneficial to reducing processing costs. At the same time, by adopting this direct action method, when the spring fails, it will not cause the disadvantage that the armrest box cover cannot be opened, which not only reduces the maintenance cost, but also expands the application field.

Therefore, the above terms should not be understood as limitations on the present invention.

[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0030] Example 1, see Figures 1 to 4 A pop-up armrest composite flip mechanism comprises an upper sheet metal part 1 and a lower sheet metal part 2 which are rotatably connected along a rotation center, wherein the upper sheet metal part 1 comprises an upper sheet metal part body, and two connecting arms 11 are symmetrically extended in a vertical direction along one end of the upper sheet metal part body, and a mating installation position 111 and a linkage mating position 112 are arranged at the protruding end of the connecting arm 11.

[0031] The lower sheet metal part 2 includes a lower sheet metal part body, and the two working ends of the lower sheet metal part body are symmetrically folded to set a rotating connection part 21, and a pull rod assembly installation position and a flip assembly installation position 213 are set on the rotating connection part. A rotation limiting part 22 is folded corresponding to the position of the rotating connection part 21, and a buffer cap 221 is sleeved on the rotation limiting part 22.

[0032] The installation positions of the pull rod assembly are symmetrically arranged on the two rotating connecting parts 21, which are notch structures 211 with an open front end. The inner working surface of the notch structure 211 is arranged from high to low along the opening direction. In order to prevent the internal structure from falling out, the opening at the open end is provided with a blocking protrusion 211a, and a tension spring fixing position 212 located on the horizontal working surface 20 of the lower sheet metal body. The tension spring fixing position 212 is a connecting hole that can enable the connecting end of the tension spring to be hooked to achieve connection. Of course, the number of tension spring fixing positions 212 is consistent with the number of notch structures 211.

[0033] The tie rod assembly 4 matched with the upper sheet metal part 1 and the lower sheet metal part 2 interacts with the upper sheet metal part 1 after being connected to the lower sheet metal part 2 through the tie rod assembly mounting position. The specific structure is as follows.

[0034] The pull rod assembly includes a long pull rod 41, a first tension spring 42 and a second tension spring 43. The two ends of the long pull rod 41 are transversely inserted into the symmetrically arranged slot structure 211, and the two ends of the long pull rod 41 extend laterally from the slot to keep the long pull rod parallel to the horizontal working surface of the lower sheet metal body. The blocking protrusion 211a prevents the long pull rod 41 from longitudinally escaping from the slot structure 211 and is located at the linkage matching position 112. The two extended ends of the long pull rod 41 can move along the slot structure 211 in a direction away from the opening in the working state, directly applying a thrust to the linkage matching position 112 of the upper sheet metal part 1.

[0035] Of course, in order to prevent the friction between the long pull rod 41 and the inner working surface of the notch structure 211 from affecting the use effect and service life of the workpiece, protective sleeves are provided at both ends of the long pull rod 41. Tension spring limiting grooves 411 are provided at two positions near the ends of the long pull rod 41 for connecting and limiting the first tension spring 42 and the second tension spring 43.

[0036] The first tension spring 42 and the second tension spring 43 are arranged vertically to the long pull rod 41. The working ends of the first tension spring 42 and the second tension spring 43 are both mounted on the long pull rod 41 and are located in the tension spring limiting groove 411. The connecting ends of the first torsion spring and the second torsion spring are connected to the tension spring fixing position 212, so that the first tension spring 42 and the second tension spring 43 are located in the space formed by the horizontal working surface 20 of the lower sheet metal body and the long pull rod 41.

[0037] The flip assembly 3 includes an axle pin 31 and a friction member 32 which is sleeved on the axle pin 31 and locked with the upper sheet metal part 1 and the lower sheet metal part 2. A blocking cap 311 is integrally provided at the end of the axle pin 31. The protruding end of the axle pin 31 is integrally provided with a partition member mounting position 313, a friction member mounting position 314 and an anti-slip member mounting position 315 in sequence. The anti-slip member 312 is installed through the anti-slip member mounting position 315 and is located at the end of the protruding end.

[0038] The friction member 32 is installed between the blocking cap 311 and the anti-dropping member 312 through the friction member installation position 314. The friction member 32 includes a plurality of sleeves sleeved on the shaft pin 31 and located between the upper sheet metal member 1 and the lower sheet metal member 2 and at the outer working surface of the upper sheet metal member.

[0039] One of the shaft sleeves is located at the partition member installation position 313 to maintain a space partition between the upper sheet metal member 1 and the lower sheet metal member 2. In this way, when the upper sheet metal member 1 is in motion, it will not cause interference to the lower sheet metal member 2, thereby ensuring the stability of opening.

[0040] The working principle of the above technical solution is as follows: when the upper sheet metal part 1 is unlocked, under the tension of the first tension spring 42 and the second tension spring 43, the long pull rod 41 can be pulled in the slot structure 211 to move in the direction of the horizontal working surface 20 of the lower sheet metal body, so that the two ends of the long pull rod 41 extending laterally from the slot apply a thrust to the linkage matching position 112 of the upper sheet metal part 1. Since the inner working surface of the slot structure 211 is arranged from high to low along the opening direction, when the upper sheet metal part 1 is applied with a thrust, it can complete a rotation of no more than 10 degrees to realize the opening action. Subsequently, through the friction of the flip component 3, The upper sheet metal part 1 realizes a flipping action with an extreme position of 75° and hovers at any position. Of course, in order to prevent excessive opening, the connecting arm 11 will interfere with the rotation limit part 22 after rotating to the set position, thereby preventing further opening action. In order to prevent the connecting arm 11 from interfering with the rotation limit part 22 and affecting the use effect and service life of the workpiece, a buffer cap 221 is sleeved on the rotation limit part 22. In this way, the opening action of the upper sheet metal part can be realized, eliminating the auxiliary restriction of the opening angle by the transition part, and even if the tension spring fails, it will not cause the disadvantage that the armrest box cover cannot be opened.

[0041] Example 2, see Figures 5 to 7 A pop-up armrest composite flip mechanism comprises an upper sheet metal part 1 and a lower sheet metal part 2 which are rotatably connected along a rotation center, wherein the upper sheet metal part 1 comprises an upper sheet metal part body, and two connecting arms 11 are symmetrically extended in a vertical direction along one end of the upper sheet metal part body, and a mating installation position 111 and a linkage mating position 112 are arranged at the protruding end of the connecting arm 11.

[0042] The lower sheet metal part 2 includes a lower sheet metal part body, and the two working ends of the lower sheet metal part body are symmetrically folded to set a rotating connection part 21, and a pull rod assembly installation position and a flip assembly installation position 213 are set on the rotating connection part. A rotation limiting part 22 is folded corresponding to the position of the rotating connection part 21, and a buffer cap 221 is sleeved on the rotation limiting part 22.

[0043] The installation position of the pull rod assembly is formed by symmetrically folding the two extended ends of the rotating connection part 21, and movable holes 214 are provided on the folded surfaces, which are arranged opposite to the working surface of the linkage matching position 112.

[0044] The pull rod includes two short pull rods 44 and a compression spring 46. The two short pull rods 44 are respectively inserted into the movable holes 214 on the folding surface and are kept parallel to each other. The front end of the short pull rod 44 extends out from the movable hole 214 and is limited by the stop member 45, so that there is a travel gap between the inner end surface of the stop member 45 and the working surface of the pull rod assembly installation position. The compression springs 46 are respectively sleeved on the short pull rods 44 and are located between the pull rod assembly installation position and the linkage matching position 112, so that the front end of the compression spring 46 abuts against the inner working surface of the linkage matching position 112, and the front end of the compression spring 46 abuts against the blocking surface 441 at the rear end of the short pull rod 44, and the rear working end of the short pull rod 44 abuts against the working surface of the linkage matching position 112.

[0045] In order to prevent wear of the working contact surface, a rubber ring 48 is sleeved on one side of the working surface of the stop member 45 close to the installation position of the pull rod assembly, and a rubber pad 47 is arranged between the rear working end of the short pull rod 44 and the outer working surface of the linkage matching position 112, which is beneficial to prevent wear and reduce noise.

[0046] The flip assembly 3 is consistent with Example 1, and also includes an axle pin 31 and a friction member 32 that is sleeved on the axle pin 31 and cooperates with the upper sheet metal part 1 and the lower sheet metal part 2 to lock. The end of the axle pin 31 is integrally provided with a blocking cap 311, and the protruding end of the axle pin 31 is integrally provided with a partition member mounting position, a friction member mounting position and an anti-slip member mounting position in sequence. The anti-slip member 312 is installed through the anti-slip member mounting position and is located at the end of the protruding end.

[0047] The friction member 32 is installed between the blocking cap 311 and the anti-dropping member 312 through the friction member installation position. The friction member 32 includes a plurality of sleeves sleeved on the shaft pin 31 and located between the upper sheet metal member 1 and the lower sheet metal member 2 and at the outer working surface of the upper sheet metal member.

[0048] One of the shaft sleeves is located at the partition installation position to maintain a space partition between the upper sheet metal part 1 and the lower sheet metal part 2. In this way, when the upper sheet metal part 1 is in motion, it will not cause interference to the lower sheet metal part 2, thereby ensuring the stability of opening.

[0049] The working principle of the above technical solution is as follows: when the upper sheet metal part 1 is unlocked, the two short pull rods 44 are pushed to move under the action of the two compression springs 46, and the rear working end of the short pull rod 44 is against the working surface of the linkage matching position 112. At this time, under the spring force of the compression spring 46, it rotates along the rotation center of the matching installation position 111 until the inner end surface of the stop member 45 is in contact with the working surface of the pull rod assembly installation position. When a thrust is applied to the upper sheet metal part 1, it can complete a rotation of no more than 10 degrees to realize the opening action. Subsequently, by turning over the assembly 3 Under the action of friction, the upper sheet metal part 1 realizes a flipping action with an extreme position of 75° and hovers at any position. Of course, in order to prevent transitional opening, the connecting arm 11 will interfere with the rotation limit part 22 after rotating to the set position, thereby preventing further opening action. In order to prevent the connecting arm 11 from interfering with the rotation limit part 22 and affecting the use effect and service life of the workpiece, a buffer cap 221 is sleeved on the rotation limit part 22. In this way, the opening action of the upper sheet metal part can be realized, and the auxiliary restriction of the opening angle by the transition part is omitted.

[0050] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
