Description

Technical Field

[0001] The utility model relates to the technical field of armrest boxes, in particular to a left-right flip-over armrest box. Background Art

[0002] The armrest and armrest box are more important components of the car's co-instrument panel. The car armrest box is set between the driver's seat and the co-pilot seat. The armrest box can be used for the car driver or co-pilot to place their arms, providing a support for the driver's elbows so that the arms can be supported on the armrest box for rest. At the same time, the armrest box has a storage function, which can provide a storage space that is convenient for the driver and co-pilot to use and store some small items. The practicality of the armrest box has made the large storage space on the car co-instrument panel gradually become the mainstream of car design.

[0003] With the improvement of living standards, the requirements for driving comfort are also getting higher and higher. In traditional technology, the armrest boxes in cars are mostly rear-flip armrest boxes. When using them, the driver can only open the cover from the front to the back, which requires raising the arm too high, making it inconvenient to open the cover and affecting the driver's normal driving. It is even more inconvenient for the co-pilot to open the cover.

[0004] To improve this defect, improvements have been made to this type of rear-flip armrest box in the prior art. For example, the Chinese invention patent with publication number CN103465832B, titled "Two-way opening automobile armrest box," discloses a two-way opening automobile armrest box comprising a hollow interior and an open top box body, a cover plate disposed on the top of the box body, a switch button disposed on the cover plate, and a flip mechanism disposed between the box body and the cover plate, comprising a locking group and a flip connection group disposed along the length of the armrest box, and a locking mechanism disposed on the cover plate corresponding to the locking group. This armrest box can be opened in both directions, making it convenient for drivers and passengers to use and having excellent practicality.

[0005] In the prior art, the armrest box that changes from a rear-flip type to a left and right side-flip structure improves the inconvenience during use. However, there is still a defect that when the flip structures on both sides are opened simultaneously by mistake, the armrest box cover will lose its connection with the armrest box seat and detach from the armrest box seat due to the opening of both sides.

[0029] See also Figures 1 to 6 A left and right rollover armrest box includes a mounting base 1, and rollover bracket mounting positions 11 are symmetrically arranged on the working surfaces on both sides along the length direction of the mounting base 1. The rollover bracket is installed through the rollover bracket mounting positions 11. Obviously, the number of rollover brackets corresponds to the number of rollover bracket mounting positions 11, including a first rollover bracket 31 and a second rollover bracket 32, and an auxiliary working surface 12 is protruded from the working surface near the first rollover bracket 31.

[0030] A reserved installation opening 20 is provided on the side of the armrest cover 2. The armrest cover 2 is connected to the cover plate seat 21 so that a cavity is formed between the two. The flip assembly 4 is installed on the cover plate seat 21 and cooperates with the first side flip bracket 31 and the second side flip bracket 32. The cover plate seat 21 is correspondingly provided with a side flip bracket connection position 212, a transverse locking mechanism installation position, a functional matching hole position and a rib 211. The functional matching hole position allows the flip assembly 4 to pass through the armrest cover 2 to achieve a specific purpose. The rib 211 not only serves the function of cooperating with the limit, but also serves the function of strengthening the strength.

[0031] The flip assembly 4 includes a first unlocking mechanism 41, a second unlocking mechanism 52, a first transverse locking mechanism 41 and a second transverse locking mechanism 42, wherein the first unlocking mechanism 41 and the second unlocking mechanism 52 are respectively inserted into the reserved installation openings 20 on both sides of the armrest cover 2 and cooperate with the first transverse locking mechanism 41 and the second transverse locking mechanism 42 located on the cover plate seat 21. The specific scheme is as follows.

[0032] The first unlocking mechanism 41 includes a first unlocking button 511 and a first linkage rod 512, wherein the first unlocking button 511 includes a button and a button seat that can keep the button at the reserved installation port 20 and can be pressed along the direction of the cavity when subjected to external force, and a first linkage rod 512 is connected to the side of the button close to the cavity, which extends into the cavity in parallel with the working surface of the cover seat 21, and a first linkage portion 512a is hollowed out on the working surface of the first linkage rod 512, and a first locking arm 513 that can cooperate with the auxiliary working surface 12 of the mounting seat 1 is provided on the side of the first linkage rod 512, and the first locking arm 513 is an elastic arm structure, and two first linkage portions 512a are provided for completing linkage with the first unlocking mechanism 41, and the first linkage portion 512a is a waist-hole-shaped structure, of course, it can also be other The structure meets the linkage requirements. The first locking arm 513 includes an integrally connected first horizontal limit portion 513a and a first vertical linkage portion 513b. The first horizontal limit portion 513a achieves locking and limiting by cooperating with the rib 211 on the cover plate seat 21. The first vertical linkage portion 513b passes through the cover plate seat 21 from the functional matching hole position on the cover plate and cooperates with the auxiliary working surface 12 to achieve locking and limiting or releasing. To ensure stability, a first auxiliary elastic rod 514 is additionally provided on the working surface of the first linkage rod. The working end of the first auxiliary elastic rod 514 extends toward the upper working surface of the first horizontal limit portion 513a and is connected to the first locking arm 513. In this way, the first auxiliary elastic rod 514 can assist the first locking arm 513 in achieving locking and releasing while enhancing the mechanical properties of the first locking arm 513 and extending its service life.

[0033] The second unlocking mechanism 52 includes a second unlocking button 521 and a second linkage rod 522. Similarly, consistent with the first unlocking mechanism 41, the second unlocking button 521 includes a second button and a second button seat that can keep the second button at the reserved installation port 20 position and can be pressed along the direction of the cavity when subjected to external force. A second linkage rod 522 is connected to the side of the second button close to the cavity. The extending end of the second linkage rod 522 has a stepped locking surface 522c. When the second linkage rod 522 is at the maximum stroke, the stepped locking surface 522c is against the extending end position of the first linkage rod 512 in the initial state. In this way, it is ensured that when the second unlocking mechanism 52 is unlocked, the first unlocking mechanism 41 is prevented from being accidentally touched and opened.

[0034] The working surface of the second linkage rod 522 is hollowed out with a second linkage portion 522a, which is consistent with the number and shape of the first linkage portion 512a. The second linkage rod 522 is laterally provided with a second locking arm 523 that can cooperate with the auxiliary working surface 12 of the mounting seat. The second locking arm 523 is an elastic arm structure. The second locking arm 523 includes an integrally connected second horizontal limit portion 523a and a second vertical linkage portion 523b. The second horizontal limit portion 523a realizes a locking limit by cooperating with the rib 211 on the cover seat 21. The second vertical linkage portion 523b passes through the cover seat 21 and cooperates with the auxiliary working surface 12 to realize the release of the locking limit. To ensure stability, a second auxiliary elastic rod 524 is provided on the working surface of the second linkage rod 522. The working end of the second auxiliary elastic rod 524 extends toward the upper working surface of the second horizontal limit portion 523a and is connected to the second locking arm 523. In this way, the second auxiliary elastic rod 524 can assist the second locking arm 523 to achieve locking and release while enhancing the mechanical properties of the second locking arm 523 and extending its service life.

[0035] The first transverse locking mechanism 41 includes a first long link 411 and a first short link 412, and the first long link 411 and the first short link 412 are both arranged on the cover plate seat 21 and are limited by the installation position of the transverse locking mechanism, so that the first long link 411 and the first short link 412 can only move along the layout direction of their length, but cannot move along the width direction. A first long link linkage head 411a is provided on the working surface of the first long link 411, and a first short link linkage head 412a is provided on the working surface of the first short link 412. The first long link linkage head 411a and the first short link linkage head 412a have the same structure and are both protruding from the working surface of the first long link 411. The surface and the bosses protruding from the working surface of the first short link 412 are respectively inserted into the two waist-shaped structures of the first linkage part 512a, the working end of the first long link 411 is provided with a first long link locking part 411b, and the working end of the first short link 412 is provided with a first short link locking part 412b. The first long link locking part 411b and the first short link locking part 412b have the same structure and adopt a lock hook structure, which passes through the cover seat 21 and cooperates with the first rollover bracket 31 and the second rollover bracket 32 ​​located below the cover seat 21. In the initial state, the lock hook structure is respectively hooked on the lower working surfaces of the first rollover bracket 31 and the second rollover bracket 32.

[0036] The second transverse locking mechanism 42 includes a second long link 421 and a second short link 422, which are also arranged on the cover seat 21. Similarly, the second long link 421 and the second short link 422 are limited by the installation position of the transverse locking mechanism, so that the second long link 421 and the second short link 422 can only move along the layout direction of their length, and cannot move along the width direction.

[0037] In order to achieve linkage with the second unlocking mechanism 52, similarly, a second long link linkage head 421a is provided on the working surface of the second long link 421, and a second short link linkage head 422a is provided on the working surface of the second short link 422. Both are convex columns protruding from the working surface of the second long link 421 and the working surface of the second short link 422. The two convex columns are respectively inserted into the two waist-shaped structures in the second linkage part 522a, and the working ends of the second long link 421 and the second short link 422 are respectively inserted into the rotating shafts of the first rollover bracket 31 and the second rollover bracket 32, and can withdraw from the rotating shafts when linked.

[0038] When the above technical solution is in use, the principle is as follows: manually press any unlocking button. Here, taking pressing the first unlocking button 511 as an example, the button pressing stroke is designed to be 6.0 mm. Of course, the stroke that suits the driving and riding conditions can also be designed according to actual conditions. When the first unlocking button 511 is pressed, the first linkage rod 512 is driven to move into the cavity, and the first long linkage rod linkage head 411a and the first short linkage rod linkage head 412a located in the first linkage part 512a will be driven, thereby causing the first long linkage rod 411 and the first short linkage rod 412 to move. The first long linkage rod locking part 411b located at the working end of the first long linkage rod 411 and the first short linkage rod locking part 412b located at the working end of the first short linkage rod 412 are respectively disengaged from the lower working surfaces of the first rollover bracket 31 and the second rollover bracket 32, so that the armrest cover 2 can be flipped and opened. At this time, the extending end of the first linkage rod 512 and the second linkage rod 522 are in contact with each other. The stepped locking surface 522c of the extended end abuts against the stepped locking surface 522c, ensuring that the second unlocking mechanism 52 cannot be unlocked in this state. To further prevent the first linkage rod 512 from resetting, in the initial state, the first horizontal limit portion 513a and the first vertical linkage portion 513b are supported by the auxiliary working surface 12 and are separated from the rib 211. At this time, due to the flipping of the armrest cover 2, the first vertical linkage portion 513b of the first locking arm 513 loses the support of the auxiliary working surface 12, causing the first horizontal limit portion 513a to be buckled on the working surface of the rib 211, avoiding the problem that the first linkage rod 512 automatically resets after unlocking, causing the second unlocking mechanism 52 to be pressed to unlock again. After the armrest cover 2 is closed, the first long link locking portion 411b and the first short link locking portion 412b are re-hooked on the lower working surfaces of the first rollover bracket 31 and the second rollover bracket 32, and there is a movable gap between the extended end of the first linkage rod 512 and the stepped locking surface 522c of the extended end of the second linkage rod 522. The first vertical linkage portion 513b rests on the auxiliary working surface 12, and the first horizontal limit portion 513a is located above the working surface of the rib 211.

[0039] The unlocking and locking of the second unlocking mechanism 52 are roughly the same as those of the first unlocking mechanism 41. When the second unlocking button 521 is pressed, the second linkage rod 522 drives the second long link 421 and the second short link 422 to move, so that the working ends of the second long link 421 and the working ends of the second short link 422 withdraw from the rotating shafts of the first rollover bracket 31 and the second rollover bracket 32, thereby realizing the flipping and opening of the armrest cover 2. Similarly, the stepped locking surface 522c of the extending end of the second linkage rod 522 abuts against the extending end of the first linkage rod 512, ensuring that the first unlocking mechanism 41 is in this state. In this state, it cannot be unlocked. In order to further prevent the second linkage rod 522 from resetting, the second horizontal limit portion 523a of the second locking arm 523 cooperates with the rib 211 to achieve locking and limiting. After the armrest cover 2 is closed, the working end of the second long link 421 and the working end of the second short link 422 are reinserted into the rotating shaft of the first rollover bracket 31 and the second rollover bracket 32, and the stepped locking surface 522c of the extending end of the second linkage rod 522 is separated from the extending end of the first linkage rod 512 and maintains a movable gap. The second horizontal limit portion 523a is separated from the rib 211 and contact-locked.

[0040] Through the mutual coordination and linkage of the first transverse locking mechanism 41, the second transverse locking mechanism 42, the first unlocking mechanism 51 and the second unlocking mechanism 52, the mutual abutment restriction designed between the first unlocking mechanism 51 and the second unlocking mechanism 52 avoids the problem of simultaneous unlocking of the unlocking buttons on both sides; at the same time, an elastic arm with a locking function buckle extends from the linkage rod, and a metal auxiliary elastic rod is attached to ensure stability. In order to avoid the problem of automatic resetting after unlocking and pressing the opposite side again to unlock, a simple structure is adopted to achieve the function of flipping either side while keeping the other side locked at the lowest cost, which has good market prospects and customer experience.

[0041] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
