Description

Technical Field

[0001] The present invention relates to an armrest box on a vehicle, in particular to an armrest box cover split-type unlocking mechanism, an armrest box using the unlocking mechanism and an unlocking method. Background Art

[0002] A vehicle armrest is typically installed between the driver and front passenger seats and consists of a body and a lid. The lid is equipped with a locking mechanism to open and lock the body. One type of armrest lid is designed to open in two directions, allowing it to be opened from both the driver's side (left) and the front passenger side (right), with both sides unable to be opened simultaneously.

[0003] Most existing unlocking actuators use a linkage mechanism to drive the locking rod. Specifically, the unlocking actuator includes a left-side control mechanism, a right-side control mechanism, and an interlocking mechanism. The left-side control mechanism includes a left button, a left linkage mechanism, and a left locking rod assembly. The left button controls the retraction of the left locking rod assembly via the left linkage mechanism. The right-side control mechanism includes a right button, a right linkage mechanism, and a right locking rod assembly. The right button controls the retraction of the right locking rod assembly via the right linkage mechanism. The interlocking mechanism functions so that when the control mechanism on one side performs the unlocking action, the control mechanism on the other side is locked, preventing both buttons from being opened simultaneously.

[0004] The above-mentioned model using a connecting rod mechanism has the following problems: the length of the connecting rod needs to be set according to the size of the armrest box cover. Armrest box covers of different lengths and widths need to be equipped with connecting rods of different models and lengths to meet the demand for reliable driving of the button → locking rod, which increases the cost of mold opening, assembly, etc. during the production process.

[0005] In addition, the invention patent publication text with application publication number CN119283743A discloses a side-flip armrest structure, which is equipped with a mis-opening limit assembly between two groups of starting assemblies. The mis-opening limit assembly is configured so that when the two moving blocks located on the left or right side of the lower cover move along the left and right directions until they abut against the mis-opening limit assembly, the two moving blocks on the other side are restricted from moving along the left and right directions, thereby playing the role of interlocking the opening of the opposite side.

[0006] This interlocking mechanism also has the following problems: the length and size of the moving block and the limit block need to be set according to the size of the armrest box cover, especially limited by the width of the left and right sides of the cover body. Therefore, armrest box covers of different widths need to be equipped with moving blocks and limit blocks of different models and lengths to meet the requirements of reliable drive of the button → interlocking mechanism (limiting component), which also increases the cost of mold opening, assembly, etc. during the production process.

[0051] Second, the modules are connected by ropes, breaking the size limitations of armrest boxes and armrest covers. The main drive module and the interlocking module are connected entirely by flexible ropes, replacing rigid connecting rods.

DETAILED DESCRIPTION

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0070] The armrest box of a vehicle is usually arranged between the driver's seat and the co-driver's seat, and includes a box body and an armrest box cover. The armrest box cover is arranged on the top of the box body. Opening the armrest box cover can expose the internal space of the box body for storing items.

[0071] like Figures 1 to 4 ,as well as Figure 11 and Figure 12 The figure shows the internal structure of the armrest box cover 200 of the armrest box provided in this embodiment, so as to demonstrate the armrest box cover double-leaf unlocking mechanism 100 provided in this embodiment. The armrest box cover 200 is hinged to the top of the box body via a rotating shaft. A base can be provided on the top of the box body, and the rotating shaft of the armrest box cover 200 is hinged to the base.

[0072] In this embodiment, the left side of the armrest box cover 200 is hinged to the left side of the box body (the side close to the driver's seat) through the left front shaft 201 and the left rear shaft 202, and the right side of the armrest box cover 200 is hinged to the right side of the box body (the side close to the passenger seat) through the right front shaft 203 and the right rear shaft 204. When the left front shaft 201 and the left rear shaft 202 are unlocked, and the right front shaft 203 and the right rear shaft 204 are locked, the armrest box cover 200 can be opened from the left side and the right side is locked; when the right front shaft 203 and the right rear shaft 204 are unlocked, and the left front shaft 201 and the left rear shaft 202 are locked, the armrest box cover 200 can be opened from the right side and the left side is locked. The shafts on both sides cannot be unlocked at the same time to prevent the armrest box cover 200 from being separated from the box body as a whole.

[0073] like Figures 1 to 4 、 Figure 11 and Figure 12 As shown, the armrest cover split unlocking mechanism 100 includes a pair of main drive modules 101, a pair of slave drive modules 102, and an interlocking module 103. The main drive module 101 includes a left front drive module 101L disposed on the left front side and a right front drive module 101R disposed on the right front side; the slave drive module 102 includes a left rear drive module 102L disposed on the left rear side and a right rear drive module 102R disposed on the right rear side.

[0074] The interlocking module 103 includes a left locking assembly 103L and a right locking assembly 103R. The left front drive module 101L, the left locking assembly 103L, and the left rear drive module 102L are connected by a left rope r1; the right front drive module 101R, the right locking assembly 103R, and the right rear drive module 102R are connected by a right rope r2.

[0075] like Figure 3 、 Figure 4 、 Figure 12 As shown, the right front driving module 101R is unlocked, and the right rear driving module 102R is driven to unlock through the connection transmission of the right rope r2, that is, the right front rotating shaft 203 and the right rear rotating shaft 204 are driven to leave the box body, and the right locking assembly 103R is synchronously driven to lock the left locking assembly 103L, so that the armrest box cover 200 can be opened from the right side and the left side is locked. Similarly, the left front driving module 101L is unlocked, and the left rear driving module 102L is driven to unlock through the connection transmission of the left rope r1, that is, the left front rotating shaft 201 and the left rear rotating shaft 202 are driven to leave the box body, and the left locking assembly 103L is synchronously driven to lock the right locking assembly 103R, so that the armrest box cover 200 can be opened from the left side and the right side is locked.

[0076] It can be seen that the armrest box cover double-opening unlocking mechanism provided by the present invention achieves at least the following two technical effects, thereby reducing mold opening costs, lowering assembly difficulty, and improving production efficiency:

[0077] First, modular production and assembly. The entire mechanism consists of three modules: the master drive module, the slave drive module, and the interlocking module. During manufacturing, each module can be standardized and mass-produced. During assembly, each module simply needs to be installed in its corresponding position on the console cover.

[0078] Second, the modules are connected by ropes, breaking the size limitations of armrest boxes and armrest covers. Flexible ropes replace rigid connecting rods in the transmission link between the master drive module, interlocking module, and slave drive module. Once the modules are assembled, production and assembly can be completed simply by adjusting the rope length to accommodate different armrest cover sizes, allowing for adaptability to various armrest cover shapes and sizes.

[0079] First, let's look at the interlocking module 103. Figure 5 、 Figure 6 、 Figure 13 As shown, the left locking assembly 103L includes a rotatable left rope winder 10L and a left locker 20L, and the right locking assembly 103R includes a rotatable right rope winder 10R and a right locker 20R. The left rope winder 10L, the left locker 20L, the right rope winder 10R, and the right locker 20R are arranged in a centrally symmetrical manner.

[0080] The left rope r1 is wound around the left rope winder 10L, and the right rope r2 is wound around the right rope winder 10R. When driven by the left front drive module 101L, the left rope r1 drives the left rope winder 10L to rotate forward, causing the left locking device 20L to rotate backward and lock the right rope winder 10R, restricting rotation of the right rope winder 10R and thereby locking the right side mechanism (right front drive module 101R, right rear drive module 102R, and right locking assembly 103R). Similarly, when driven by the right front drive module 101R, the right rope r2 drives the right rope winder 10R to rotate forward, causing the right locking device 20R to rotate backward and lock the left rope winder 10L, restricting rotation of the left rope winder 10L and thereby locking the left side mechanism (left front drive module 101L, left rear drive module 102L, and left locking assembly 103L).

[0081] Specifically in this embodiment, Figure 5 and Figure 6As shown, the left cord winder 10L includes a left cord winding portion 11L and a left locking portion 12L. The left locking portion 12L includes a left first protrusion 13L and a left first recess 14L. The left locker 20L includes a left second protrusion 21L, a left third protrusion 22L, and a left second recess 23L located between the left second protrusion 21L and the left third protrusion 22L. Similarly, the right cord winder 10R includes a right cord winding portion 11R and a right locking portion 12R. The right locking portion 12R includes a right first protrusion 13R and a right first recess 14R. The right locker 20R includes a right second protrusion 21R, a right third protrusion 22R, and a right second recess 23R located between the right second protrusion 21R and the right third protrusion 22R.

[0082] like Figure 5 As shown, when unlocked, the left first protrusion 13L is located within the left second recess 23L, the left third protrusion 22L is away from the right first recess 14R, the right first protrusion 13R is located within the right second recess 23R, and the right third protrusion 22R is away from the left first recess 14L. Thus, neither the left locking assembly 103L nor the right locking assembly 103R locks the other, and the armrest box cover 200 can be opened from either side.

[0083] like Figure 6 As shown, when driven by the left front drive module 101L, the left rope r1 drives the left rope winder 10L to rotate forward, causing the left first protrusion 13L to leave the left second recess 23L. Subsequently, the left locker 20L rotates backward, and the left third protrusion 22L enters the right first recess 14R, locking the right rope winder 10R. Conversely, when the left rope winder 10L rotates backward, the left first protrusion 13L pushes the left second protrusion 21L, driving the left locker 20L to rotate forward and return to its original position. The left third protrusion 22L leaves the right first recess 14R, releasing the right rope winder 10R.

[0084] Similarly, when driven by the right front drive module 101R, the right rope r2 drives the right rope winder 10R to rotate forward, causing the right first protrusion 13R to leave the right second recess 23R. Subsequently, the right locker 20R rotates in the reverse direction, and the right third protrusion 22R enters the left first recess 14L, locking the left rope winder 10L. Conversely, when the right rope winder 10R rotates in the reverse direction, the right first protrusion 13R pushes the right second protrusion 21R, driving the right locker 20R to rotate forward and return to its original position. The right third protrusion 22R leaves the left first recess 14L, releasing the left rope winder 10L.

[0085] Furthermore, the interlocking module 103 has a third bottom housing k3. The left and right rope winders 10L and 10R are respectively connected to the third bottom housing k3 via first springs s1. When the left and right rope winders 10L and 10R rotate forward, the first springs s1 are stretched, and the retraction force of the first springs s1 drives the left and right rope winders 10L and 10R to rotate backward and reset.

[0086] The left and right lockers 20L and 20R are each connected to the third bottom case k3 via the second spring s2. When the left first protrusion 13L leaves the left second recess 23L, or the right first protrusion 13R leaves the right second recess 23R, the left and right lockers 20L and 20R are driven in the opposite directions by the retraction force of the second spring s2. When the left first protrusion 13L pushes the left locker 20L to rotate forward and return, or when the right first protrusion 13R pushes the right locker 20R to rotate forward and return, the second spring s2 is stretched.

[0087] Preferably, if Figure 13 As shown, the left and right rope winding sections 11L and 11R are disc-shaped, with the left and right ropes r1 and r2 wound around the circumferential sidewalls of the left and right rope winding sections 11L and 11R, respectively. The left and right locking sections 12L and 12R are arranged in a bird's beak shape on the circumferential sidewalls of the left and right rope winding sections 11L and 11R, respectively. The left and right first protrusions 13L and 13R are located at the front ends of the bird's beaks, and the left and right first recesses 14L and 14R are located at the tops of the bird's beaks. A first spring s1 is positioned near the front end of the bird's beaks and between the third bottom case k3, with its length aligned with the tangential direction of the movement of the left and right locking sections 12L and 12R.

[0088] Both the left and right locking devices 20L and 20R include a positioning portion 24, an extension portion 25, and a locking portion 26. The positioning portion 24 is semicircular, with its rotation axis connected to the third housing k3. The extension portion 25 is located between the positioning portion 24 and the locking portion 26 and is rectangular. The left second protrusion 21L, the left third protrusion 22L, the left second recess 23L, and the right second protrusion 21R, the right third protrusion 22R, and the right second recess 23R are located on the front end of the locking portion 26. The left second protrusion 21L, the left third protrusion 22L, and the right second protrusion 21R, the right third protrusion 22R, and the right third protrusion 22R form an acute angle. The left second recess 23L and the right second recess 23R match the left first protrusion 13L and the right first protrusion 13R, respectively. The second spring s2 is provided between the third bottom case k3 and a position close to the left third protrusion 22L and the right third protrusion 22R, and its length direction is consistent with the tangential direction of the movement of the left locker 20L and the right locker 20R.

[0089] Under this structural design, the locking and releasing actions between the components of the interlocking module 103 are most flexible and smooth, the movement is more efficient, and the component shapes and structures are simple, achieving efficient interlocking function at a lower production cost.

[0090] Next, let’s look at the main driver module 101. Figure 7 and Figure 8 As shown, the main drive module 101 includes a button assembly 30 and a shaft drive assembly 40. The button assembly 30 has a first inclined surface x1. In this embodiment, the button assembly 30 includes a button 31 and a spring lock 32, and the first inclined surface x1 is provided on the housing of the spring lock 32.

[0091] The shaft drive assembly 40 includes a slide rail 41 and front shafts 201 and 203. The slide rail 41 has a second inclined surface x2 that mates with the first inclined surface x1. The button assembly 30 drives the slide rail 41 through the first and second inclined surfaces x1 and x2, which in turn drives the front shafts 201 and 203 to move, thereby controlling the opening and closing of the main drive module 101.

[0092] The slide rail 41 connects and drives the left rope r1 or the right rope r2. Specifically, the first ends of the left rope r1 and the right rope r2 are connected to the slide rail 41, respectively passing through the left rope winder 10L and the right rope winder 10R, and the second ends are connected to the rear shafts 202 and 204 of the slave drive module 102.

[0093] The main drive module 101 also includes a first base housing k1. A third spring s3 is interposed between the end of the slide rail 41 and the first base housing k1. When the button 31 is pressed, the first inclined surface x1 and the second inclined surface x2 drive the slide rail 41 forward, thereby pulling the left rope r1 or the right rope r2, and extending the third spring s3. The retracting force of the third spring s3 resets the slide rail 41.

[0094] The shaft drive assembly 40 also includes a rotating connecting rod 42, the ends of which are rotatably connected to the slide rail 41 and the front shafts 201 and 203, respectively. The slide rail 41 moves forward and backward, driving the front shafts 201 and 203 to move via the rotating connecting rod 42. The advantage of using a connecting rod drive rather than a rope drive here is that since the slide rail 41 and the front shafts 201 and 203 are in the same main drive module 101, it is an intra-module drive. The use of a rigid connecting rod drive not only has high drive efficiency and stable operation, but also facilitates modular manufacturing of the production line, eliminating the need to consider the adaptability of the armrest box cover size as required for inter-module drive.

[0095] Finally, let’s look at the slave driver module 101. Figure 9 and Figure 10As shown, the slave drive module 101 includes rear shafts 202, 204 and a second bottom shell k2. The rear shafts 202, 204 are connected to the second end of the left rope r1 or the right rope r2. A torsion spring s4 is provided between the rear shafts 202, 204 and the second bottom shell k2. When the button 31 is pressed, the slide rail 41 moves forward, pulling the left rope r1 or the right rope r2, which in turn drives the rear shafts 202, 204 to move, unlocking the slave drive module 102 and accumulating force in the torsion spring s4. The restoring force of the torsion spring s4 drives the rear shafts 202, 204 back to the locked state. Using a torsion spring s4 instead of an ordinary spring, while using materials of the same quality, provides greater force, more stable application, and less likely to deflect.

[0096] The following, in conjunction with the unlocking method of the armrest box cover split-type unlocking mechanism provided in this embodiment, dynamically and intuitively demonstrates the unexpected effects achieved by the armrest box cover split-type unlocking mechanism in terms of usage while realizing modular production and assembly, including:

[0097] -How to unlock the left side of the armrest box cover:

[0098] When the left button 31L is pressed, the left front driving module 101L is unlocked, driving the left rope r1 to move in the first direction. The left rope r1 drives the left rear driving module 102L to unlock, and the armrest box cover 200 can be opened from the left side.

[0099] When the left rope r1 moves in the first direction, the left rope winder 10L is driven to rotate forward at the same time, the left first protrusion 13L leaves the left second recess 23L, the left locker 20L rotates reversely, the left third protrusion 22L enters the right first recess 14R, locking the right rope winder 20R, and the right side of the armrest box cover 200 is locked.

[0100] -How to lock the left side of the armrest box cover:

[0101] The left button 31L is released, the left front driving module 101L is locked, and the left rope r1 is driven to move in the opposite direction of the first direction. The left rope r1 drives the left rear driving module 102L to lock, and the left side of the console box cover 200 is locked.

[0102] When the left rope r1 moves in the opposite direction of the first direction, the left rope winder 10L is driven to rotate in the opposite direction at the same time. The left first protrusion 13L pushes the left second protrusion 21L to drive the left locker 20L to rotate forward and reset. The left third protrusion 22L leaves the right first recess 14R, releasing the right rope winder 20R, and the right side of the armrest box cover 200 is unlocked.

[0103] -How to unlock the right side of the armrest box cover:

[0104] When the right button 31R is pressed, the right front driving module 101R is unlocked, driving the right rope r2 to move in the first direction. The right rope r2 drives the right rear driving module 102R to unlock, and the armrest box cover 200 can be opened from the right side.

[0105] When the right rope r2 moves in the first direction, the right rope winder 10R is driven to rotate forward at the same time, the right first protrusion 13R leaves the right second recess 23R, the right locker 20R rotates reversely, and the right third protrusion 22R enters the left first recess 14L, locking the left rope winder 20L, and the left side of the armrest box cover 200 is locked.

[0106] -How to lock the right side of the armrest box cover:

[0107] The right button 31R is released, the right front driving module 101R is locked, and the right rope r2 is driven to move in the opposite direction of the first direction. The right rope r2 drives the left rear driving module 102R to lock, and the right side of the console box cover 200 is locked.

[0108] When the right rope r2 moves in the opposite direction of the first direction, it drives the right rope winder 10R to rotate in the opposite direction at the same time. The right first protrusion 13R pushes the right second protrusion 21R to drive the right locker 20R to rotate forward and reset. The right third protrusion 22R leaves the left first recess 14L, releasing the left rope winder 20L, and the left side of the armrest box cover 200 is unlocked.

[0109] As can be seen, the armrest cover split-type unlocking mechanism provided by the present invention operates almost entirely within the module itself, with inter-module movement limited to the movement of the rope. Therefore, not only is the mechanism unrestricted by the shape and size of the armrest cover during production and assembly, but during use, component movement virtually has no impact on other components, structures, or devices within the armrest cover.
