Description

Technical Field

[0001] This application relates to the field of automotive double-opening armrest technology, specifically to an automotive double-opening armrest unlocking mechanism. Background Technology

[0002] A car armrest, also known as a center console, is a car accessory installed between two seats and belongs to the automotive interior system. Its ergonomic design aims to provide a place for the driver's arm to rest during long drives, preventing soreness, numbness, and stiffness. To enhance functionality, storage compartments are often included within the armrest for storing small items. However, most existing armrests can only open from one direction. In practice, if the passenger wants to retrieve items from the storage compartment, they need to reach the driver's seat to open the armrest, potentially affecting driving safety. Rear-opening armrests require a significant angle to fully open, also making accessing items inconvenient. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of this, this application provides a double-opening armrest unlocking mechanism for automobiles, which allows either the driver's or passenger's seat to open the armrest box from their own side, thus not affecting the driver's driving safety. Moreover, the opening angle can be adjusted by the user and will not flip back too far, making it very convenient to store and retrieve items.

[0005] (II) Technical Solution

[0006] To solve the aforementioned technical problem, this utility model provides a double-opening armrest unlocking mechanism for automobiles, including a lower housing, a cover plate assembly, a left button, a right button, a left locking tongue assembly, a right locking tongue assembly, and a push plate assembly. The cover plate assembly includes at least three states: a closed state, a left open state, and a right open state. The left button and the right button are respectively provided on both sides of the cover plate assembly. The left locking tongue assembly and the right locking tongue assembly are respectively provided on the side of the left button and the right button that are close to each other. The push plate assembly is provided between the left locking tongue assembly and the right locking tongue assembly. The lower housing is provided with a left hinge connection area and a right hinge connection area that correspond to and match the left locking tongue assembly and the right locking tongue assembly, respectively.

[0007] When the cover plate assembly is in the closed state, the left latch assembly is matched and connected with the left hinge connection area, and the right latch assembly is matched and connected with the right hinge connection area, so that the cover plate assembly remains in the closed state;

[0008] When the left button is pressed, the left button causes the left locking tongue assembly to disengage from the left hinge connection area, thereby releasing the connection between one side of the cover assembly and the lower housing. The left locking tongue assembly pushes the push plate assembly to the right to maintain the matching connection between the right locking tongue assembly and the right hinge connection area, so that the cover assembly is in the left open state, making the pressing of the right button ineffective.

[0009] When the right button is pressed, the right button causes the right latch assembly to disengage from the right hinge connection area, releasing the connection between one side of the cover assembly and the lower housing. The right latch assembly pushes the push plate assembly to the left to maintain the matching connection between the left latch assembly and the left hinge connection area, so that the cover assembly is in the right open state, making the pressing of the left button ineffective.

[0010] In this design, a left and a right button are provided. Pressing one of the buttons causes the left or right locking tongue assembly to retract, thus disengaging one of the left or right locking tongue assemblies from the lower housing. At this time, the push plate assembly moves to fix the button on the other side, preventing it from being pressed. This allows the locking tongue assembly to drive the cover assembly to open from the side of the left or right where the button was pressed. This allows both the driver and passenger to open the armrest box from their own side without affecting the driver's safety. The opening angle can be adjusted to prevent it from flipping back too far, making it very convenient to store and retrieve items.

[0011] Preferably, the lower housing is provided with limiting components on both the left and right sides of the push plate assembly near the left hinge connection area; when the left button is pressed, the limiting component on the left side limits the push plate assembly to prevent it from moving to the left, thus disabling the pressing of the right button; when the right button is pressed, the limiting component on the right side limits the push plate assembly to prevent it from moving to the right, thus disabling the pressing of the left button.

[0012] In this solution, by setting a limit component, the movement of the push plate component can be restricted, so that only one of the left or right buttons can be pressed to open from one side, preventing it from opening from both sides, making it more convenient to use.

[0013] As a further preferred embodiment, a first bracket is connected to the lower housing, and a rotating arm is provided on the side of the first bracket near the left locking tongue assembly. The first bracket and the rotating arm are connected by a fixed rotating shaft.

[0014] The left side of the rotating arm is provided with a through hole, and the first bracket is provided with a bracket connection area. The left locking tongue assembly can pass through the through hole and cooperate with the bracket connection area. The left locking tongue assembly is provided with a first elastic element for driving the cover plate assembly to open. The two ends of the first elastic element are respectively connected to the cover plate assembly and the rotating arm, and always have the tendency to drive the cover plate assembly to open when the cover plate assembly is in the closed state.

[0015] The right side of the rotating arm is provided with a connection and installation area, the right locking tongue assembly is connected to the connection and installation area, and a second elastic element is sleeved on the fixed rotating shaft. The second elastic element is located in the first bracket and its two ends are respectively connected to the rotating arm and the first bracket. The second elastic element always has the tendency to drive the rotating arm to open when the cover plate assembly is closed.

[0016] Pressing the left button causes the left locking tongue assembly to retract and disconnect from the bracket connection area, so that the rotating arm opens under the rebound force of the second elastic element, thereby driving the cover plate assembly to open from the right side to achieve the left open state of the cover plate assembly.

[0017] Pressing the right button causes the right locking tongue assembly to retract, thereby disengaging it from the connection mounting area. This allows the cover assembly to open from the left side under the restoring force of the first elastic element, achieving the right-open state of the cover assembly.

[0018] In this solution, the cover plate assembly can be popped up by setting the first elastic element. After the connection between the left locking tongue assembly and the lower housing is canceled, the second elastic element pops up the cover plate assembly to open. After the connection between the right locking tongue assembly and the lower housing is canceled, the first elastic element opens the rotating arm, and the rotating arm drives the cover plate assembly to pop up and open.

[0019] As a further preferred embodiment, the limiting component includes an unlocking block, which is provided on the side of the push plate assembly away from the rotating arm. A limiting block is provided on the lower side of the unlocking block, and a third elastic element is provided on the unlocking block. The unlocking block can abut against the lower housing. The unlocking block is provided with a first tooth, and the limiting block is provided with a second tooth. The first tooth and the second tooth mesh to drive the limiting block to move back and forth. The limiting block can abut against the push plate assembly to restrict the reset movement of the push plate assembly.

[0020] In this solution, a third elastic element is used to lift the unlocking block, which in turn causes the limiting block to move backward, thereby limiting the push plate assembly and preventing it from returning to its original position, thus keeping the cover plate assembly in the open state.

[0021] As a further preferred embodiment, the left locking tongue assembly includes a first pivot pin, a first connecting rod turntable, and a left locking tongue. The left locking tongue is located on the side of the left button near the right button. The side of the left locking tongue away from the unlocking block is connected to the first connecting rod turntable. The side of the first connecting rod turntable near the rotating arm is connected to the first pivot pin. The first pivot pin passes through the through hole of the rotating arm and engages with the bracket connection area of ​​the first bracket. The first elastic element is sleeved on the first pivot pin. A fastening rotating shaft is sleeved on the first pivot pin, and a first damping assembly is sleeved on the fastening rotating shaft.

[0022] In this solution, by setting a first linkage turntable, the left button drives the left locking tongue to move downward, and the left locking tongue drives the first linkage turntable to move downward, causing the other end of the first linkage turntable to move upward, thereby driving the first pin shaft to move upward and disengage from the first bracket. Thus, under the action of the second elastic element, the rotating arm is opened, thereby driving the cover plate assembly to open. Furthermore, by setting a first damping component, the reset rotation speed of the first elastic element can be reduced.

[0023] As a further preferred embodiment, the right locking tongue assembly includes a right locking tongue, a second connecting rod turntable, and a second pin. The right locking tongue is located on the side of the right button near the left button. The side of the right locking tongue away from the unlocking block is connected to the second connecting rod turntable. The side of the second connecting rod turntable near the rotating arm is connected to the second pin. The second pin is engaged with the connection mounting area of ​​the rotating arm. A second damping assembly is sleeved on the fixed rotating shaft.

[0024] In this solution, by setting a second linkage turntable, the right button drives the right locking tongue to move downward, and the right locking tongue drives the second linkage turntable to move downward, causing the other end of the second linkage turntable to move upward, thereby driving the second pin shaft to move upward and disengage from the rotating arm, thus opening the cover plate assembly under the action of the first elastic element; by setting a second damping component, the reset rotation speed of the second elastic element can be slowed down.

[0025] Preferably, the cover plate assembly includes an inner cover plate and an outer cover plate, with the outer cover plate disposed on the outer side of the inner cover plate and the outer cover plate being snapped onto the inner cover plate. The inner cover plate is provided with the left locking tongue assembly, the right locking tongue assembly, the left button, the right button, and the push plate assembly.

[0026] As a further preferred embodiment, the push plate assembly includes a left push plate and a right push plate. Both the left and right latches are provided with inclined sliding grooves. Both the left and right push plates are provided with sliding blocks. The sliding blocks can slide along the sliding grooves. The movement of the left or right latches drives the sliding blocks to slide along the sliding grooves, thereby driving the left or right push plate to move closer to the other side. The movement of the left or right push plate restricts the other from moving.

[0027] In this solution, by setting a left push plate and a right push plate, when the left push plate moves to the right, the right push plate is restricted from moving to the left, so that the cover plate assembly can only be opened from one side and cannot be opened from the other side.

[0028] As a further preferred embodiment, both the left push plate and the right push plate are provided with limiting protrusions on their upper sides, and the limiting protrusions cooperate with the limiting block to limit the left push plate or the right push plate.

[0029] In this design, by setting a limiting protrusion and a limiting block, the left or right push plate cannot return to its original position to the left or right.

[0030] As a further preferred embodiment, a transmission tooth is provided on one side of the left push plate, a third tooth is provided on one side of the left push plate, a fourth tooth is provided on the transmission tooth to mesh with the third tooth, a limit stop is provided on the transmission tooth, and a limit groove is provided on the right push plate. The limit block cooperates with the limit groove to limit the right push plate and prevent it from moving.

[0031] In this design, by setting transmission teeth, when the left push plate moves to the right, the third and fourth teeth mesh to drive the transmission teeth to rotate, thereby limiting the right push plate to a position where it cannot move. When the right push plate moves, the transmission teeth limit the left push plate to a position where it cannot move to the left.

[0032] (III) Beneficial Effects

[0033] Compared with the prior art, the beneficial effects that this specification can achieve include at least the following:

[0034] (1) By setting a left button and a right button, pressing one of the buttons will cause the left or right locking tongue assembly to retract and release the connection between the left or right locking tongue assembly and the lower housing. At this time, the push plate assembly moves to fix the button on the other side so that it cannot be pressed. This allows the locking tongue assembly to drive the cover assembly to open from the side of the left or right side where the button is pressed. This allows the driver or passenger to open the armrest box from their own side, thus not affecting the driver's driving safety. The opening angle can be adjusted by the driver and will not flip up too much. It is very convenient to store and retrieve items.

[0035] The cover assembly can be popped up by setting the first elastic element. After the connection between the left locking tongue assembly and the lower housing is canceled, the second elastic element pops up the cover assembly to open. After the connection between the right locking tongue assembly and the lower housing is canceled, the first elastic element opens the rotating arm, and the rotating arm drives the cover assembly to pop up and open.

In the closed state of the cover plate assembly 2, the front end of the left locking tongue 54 can be inserted into the left hinge connection area 11, and the front end of the right locking tongue 61 can be inserted into the right hinge connection area 12. A first connecting rod turntable 53 is provided on the lower side of the left locking tongue 54, and a first pin is provided on the lower side of the first connecting rod turntable 53. The first pin is connected to the first connecting rod. One end of the turntable 53 is connected to the left locking tongue 54 and the other end of the first connecting rod turntable 53. A fixed rotating shaft 15 is sleeved on the first pin shaft. A first elastic element 51, which is a torsion spring, is sleeved on the fixed rotating shaft 15. A first damping assembly 56 is also sleeved on the fixed pin shaft. The first damping assembly 56 includes a damper composed of a gear shaft and a damping transmission gear 76. The damper is connected to the first elastic element 51 and can reduce the rebound speed of the first elastic element 51. The two ends of the first elastic element 51 are respectively connected to the rotating arm 14 and the inner cover plate 21. The fixed end of the first elastic element 51 is fixed to the rotating arm 14 and the rotating end of the first elastic element 51 is connected to the inner cover plate 21. The fixed end of the second elastic element 16 is fixed to the first bracket 13 and the rotating end of the second elastic element 16 is connected to the rotating arm 14.

[0073] Specifically, in this embodiment, when in the closed state, the first elastic element 51 always has the tendency to drive the cover plate assembly 2 to open, and when the connection is released, it can spring back to open the inner cover plate 21; the two ends of the first connecting rod turntable 53 are provided with insertion holes, and the first pin and the left locking tongue 54 are provided with insertion blocks inserted into the insertion holes to drive the first connecting rod turntable 53 to rotate; when the left button 3 is pressed, the left button 3 drives the left locking tongue 54 to move downward, causing one end of the first connecting rod turntable 53 to move downward, the first connecting rod turntable 53 to rotate, and the other end of the first connecting rod turntable 53 to move upward; thereby causing the first pin to move upward, and when the cover plate assembly 2 is in the closed state, the first pin can pass through the through hole 141 and connect with the bracket connection area 131.

[0074] Specifically, in this embodiment, a second connecting rod turntable 62 is provided on the lower side of the right locking tongue 61, and a second pin 63 is provided on the lower side of the second connecting rod turntable 62. The second pin 63 is connected to one end of the second connecting rod turntable 62, and the right locking tongue 61 is connected to the other end of the second connecting rod turntable 62. Insertion holes are provided at both ends of the second connecting rod turntable 62, and insertion blocks are provided on both the second pin 63 and the right locking tongue 61, which are inserted into the insertion holes to drive the second connecting rod turntable 62 to rotate. Pressing the right button 4... The right locking tongue 61 moves downward, causing one end of the second linkage turntable 62 to move downward, and the second linkage turntable 62 rotates, causing the other end of the second linkage turntable 62 to move upward; thereby causing the second pin 63 to move upward. When the cover plate assembly 2 is in the closed state, the second pin 63 can be connected to the connection mounting area 142. When the button is pressed, the second pin 63 moves upward to disengage it from the connection mounting area 142, so that the first elastic element 51 rebounds and drives the cover plate assembly 2 to open.

[0075] Specifically, in this embodiment, when the left button 3 is pressed, the first pin is disconnected from the bracket connection area 131 of the first bracket 13, and the left locking tongue 54 is disconnected from the left hinge connection area 11 of the lower housing 1. The force pressing the second elastic member 16 and the rotating arm 14 is released, and the second elastic member 16 can drive the rotating arm 14 to rotate. As a result, the rotating arm 14 drives the inner cover plate 21 to open relative to the lower housing 1, thereby allowing the cover plate assembly 2 to open from the right side to achieve the left opening state of the cover plate assembly 2. When the right button 4 is pressed, the second pin 63 is disconnected from the connection mounting area 142 of the rotating arm 14, and the right locking tongue 61 is disconnected from the right hinge connection area 12 of the lower housing 1. The force pressing the first elastic member 51 is released, and the first elastic member 51 can drive the inner cover plate 21 to open relative to the lower housing 1, thereby allowing the cover plate assembly 2 to open from the left side to achieve the right opening state of the cover plate assembly 2. By setting a limit component, the movement of the push plate assembly 7 can be restricted, so that only one of the left button 3 or the right button 4 can be pressed to open from one side, preventing it from opening from both sides, making it more convenient to use.

[0076] Specifically, in this embodiment, both the left locking tongue 54 and the right locking tongue 61 are provided with inclined sliding grooves 73, and both the left push plate 71 and the right push plate 72 are provided with sliding blocks 74. The sliding blocks 74 can slide along the sliding grooves 73. One side of the left push plate 71 is provided with a transmission tooth 76 and a third tooth 711. The transmission tooth 76 is provided with a fourth tooth 761 that meshes with the third tooth 711. The transmission tooth 76 is provided with a limit stop 77. The right push plate 72 is provided with a limit groove 78. The limit block 81 cooperates with the limit groove 78 to limit the right push plate 72 and prevent it from moving. When it is necessary to open the cover assembly 2 from the left, pressing the left button 3 causes the left locking tongue 54 to move downwards. The left locking tongue 54 then causes the left push plate 71 to move to the right. At this time, the third tooth 711 and the fourth tooth 761 mesh and drive the transmission gear 76. The limiting block 77 of the transmission gear 76 cooperates with the limiting groove 78 of the right push plate 72, preventing the right push plate 72 from moving to the left and thus preventing the right button 4 from being pressed, thus preventing the cover assembly 2 from being opened from the right. When it is necessary to open the cover assembly 2 from the right... When the right button 4 is pressed, the right locking tongue 61 moves downward, and the right locking tongue 61 moves the right push plate 72 to the left. At this time, the fourth tooth 761 of the transmission gear 76 engages with the third tooth 711, making it impossible for the left push plate 71 to move to the right, thus preventing the left button 3 from being pressed and the cover plate assembly 2 from being opened from the left. The left push plate 71, the right push plate 72, the left locking tongue 54, the right locking tongue 61 and the transmission gear 76 are all equipped with torsion springs, and these torsion springs are all connected to the inner cover plate 21 to facilitate its reset.

[0077] Specifically, in this embodiment, both the left push plate 71 and the right push plate 72 are provided with unlocking blocks 8 on the side away from the rotating arm 14. A limit block 81 is provided on the lower side of the unlocking block 8, and a third elastic element 82 is provided on the unlocking block 8. The unlocking block 8 can abut against the lower housing 1. When the cover plate assembly 2 is opened, since the unlocking block 8 is no longer abutting against the lower housing 1, the unlocking block 8 rotates counterclockwise under the action of the rebound force of the third elastic element 82, thereby pushing the limit block 81 closer to the rotating arm 14. When one side of the rotating arm 14 moves, the unlocking block 8 is provided with a first tooth 83, and the limiting block 81 is provided with a second tooth 84. The first tooth 83 and the second tooth 84 mesh with each other to drive the limiting block 81 to move back and forth. The limiting block 81 can abut against the push plate assembly 7 to limit the reset movement of the push plate assembly 7. The upper side of the left push plate 71 and the right push plate 72 are provided with a limiting protrusion 75. The limiting protrusion 75 cooperates with the limiting block 81 to limit the left push plate 71 or the right push plate 72.

[0078] Specifically, in this embodiment, the opening process is as follows: Pressing the left button 3 causes the left locking tongue 54 to slide and unlock with the left hinge connection area 11 of the lower housing 1. At the same time, it drives the first connecting rod turntable 53 to rotate and causes the first pin to slide away from the bracket connection area 131 to unlock. At this time, the front and rear sides of the left locking tongue assembly 5 have been unlocked. The rotating arm 14 rotates under the drive of the second elastic element 16, and the cover plate assembly 2 rotates and opens under the drive of the rotating arm 14. At the same time, the left push plate 71 drives the transmission tooth 76 to rotate. After rotation, it restricts the sliding of the right push plate 72. At this time, the unlocking block 8 rotates under the drive of the third elastic element 82, and then the engagement of the first tooth 83 and the second tooth 84 drives the limiting block 81 to slide, restricting the left push plate 71 to return to its original position and preventing the transmission tooth 76 from rotating and causing the limiting block to fail.

[0079] Pressing the right button 4 causes the right locking tongue 61 to slide and unlock with the right hinge connection area 12 of the lower housing 1. At the same time, it causes the second connecting rod turntable 62 to rotate, causing the second pin 63 to slide away from the connection mounting area 142 and unlock. At this time, the front and rear sides of the right locking tongue assembly 6 are unlocked. The first elastic element 51 rebounds and causes the cover plate assembly 2 to rotate and open. At the same time, it restricts the sliding of the left push plate 71. At this time, the unlocking block 8 rotates under the action of the third elastic element 82, and then the engagement of the first tooth 83 and the second tooth 84 causes the limiting block 81 to slide, restricting the right push plate 72 to return to its original position and preventing the transmission tooth 76 from rotating and causing the limiting to fail.

[0080] Closing process: Manually push the cover plate to rotate and close. When the unlocking block 8 touches the lower housing 1, the unlocking block 8 rotates, causing the limiting block 81 to slide, thereby disengaging the limiting block 81 from the left push plate 71. The left push plate 71 returns to its original position under the action of the torsion spring, causing the left button 3, transmission gear 76, left locking tongue 54, and first pin to return to their original positions. After the cover plate assembly 2 is pressed to the bottom, the left locking tongue 54 enters the left hinge connection area 11, and the first pin 52 enters the bracket connection area 131, thereby achieving the closing and locking of the handrail.

[0081] The cover plate is manually rotated to close. When the unlocking block 8 touches the lower housing 1, the unlocking block 8 rotates, causing the limiting block 81 to slide, thus disengaging the limiting block 81 from the right push plate 72. The right push plate 72 returns to its original position under the action of the torsion spring, causing the right button 4, transmission gear 76, right locking tongue 61, and second pin 63 to return to their original positions. After the cover plate assembly 2 is pressed to the bottom, the right locking tongue 61 enters the right hinge connection area 12, and the second pin enters the connection installation area 142, thereby achieving the closing and locking of the handrail.

[0082] Specifically, in this embodiment, by setting a left button 3 and a right button 4, pressing one of the buttons will cause the left locking tongue assembly 5 or the right locking tongue assembly 6 to retract, thereby disengaging one of the left locking tongue assembly 5 or the right locking tongue assembly 6 from the lower housing 1. At this time, the push plate assembly 7 moves to fix the button on the other side so that it cannot be pressed, thereby allowing the locking tongue assembly to drive the cover assembly 2 to open from the side of the left or right where the button was pressed. This allows both the driver's seat and the passenger seat to open the armrest box from their own side, thus not affecting the driver's driving safety. Moreover, the opening angle can be adjusted by the driver and will not flip up too much, making it very convenient to store and retrieve items.

[0083] Specifically, in this embodiment, the cover plate assembly 2 can be popped up by setting the first elastic element 51. After the connection between the left locking tongue assembly 5 and the lower housing 1 is canceled, the second elastic element 16 pops up the cover plate assembly 2 to open. After the connection between the right locking tongue assembly 6 and the lower housing 1 is canceled, the first elastic element 51 opens the rotating arm 14, and the rotating arm 14 drives the cover plate assembly 2 to pop up and open.

[0084] Specifically, in this embodiment, by setting the third elastic element 82 to drive the unlocking block 8 to lift, the unlocking block 8 drives the limiting block 81 to move backward, thereby limiting the push plate assembly 7, preventing the push plate assembly 7 from returning to the original position, and keeping the cover plate assembly 2 in the open state.

[0085] Specifically, in this embodiment, by setting the first connecting rod turntable 53, the left button 3 drives the left locking tongue 54 to move downward, the left locking tongue 54 drives the first connecting rod turntable 53 to move downward, causing the other end of the first connecting rod turntable 53 to move upward, thereby driving the first pin shaft to move upward and disengage from the connection with the first bracket 13, thereby opening the rotating arm 14 under the drive of the second elastic member 16, thereby driving the cover plate assembly 2 to open. Furthermore, by setting the first damping component 56, the reset rotation speed of the first elastic member 51 can be slowed down.

[0086] Specifically, in this embodiment, by setting a second connecting rod turntable 62, the right button 4 drives the right locking tongue 61 to move downwards, and the right locking tongue 61 drives the second connecting rod turntable 62 to move downwards, causing the other end of the second connecting rod turntable 62 to move upwards, thereby driving the second pin 63 to move upwards and disengage from the rotating arm 14, thus opening the cover plate assembly 2 under the action of the first elastic member 51. By setting a second damping component 64, the reset rotation speed of the second elastic member 16 can be reduced.

[0087] Specifically, in this embodiment, by setting a left push plate 71 and a right push plate 72, when the left push plate 71 moves to the right, the right push plate 72 is restricted from moving to the left, thus making the cover assembly 2 only openable from one side and unable to open from the other. By setting a limiting protrusion 75 to cooperate with a limiting block 81, the left push plate 71 or the right push plate 72 cannot return to its original position to the left or right. By setting a transmission tooth 76, when the left push plate 71 moves to the right, the third tooth 711 and the fourth tooth 761 mesh to drive the transmission tooth 76, thereby limiting the right push plate 72 and preventing it from moving. When the right push plate 72 moves, the transmission tooth 76 limits the left push plate 71 and prevents it from moving to the left.
