A bidirectional opening handrail box cover body transmission mechanism and handrail box

Abstract

The application provides a bidirectional opening handrail box cover transmission mechanism and a handrail box. The transmission mechanism comprises a bottom plate and a transmission assembly. The transmission assembly has a first part and a second part, which are slidingly connected and rotatably connected to the bottom plate respectively. The first part is drivingly connected with two first locking assemblies, and the second part is drivingly connected with two second locking assemblies. The first locking assemblies and the second locking assemblies located on the same side of the transmission assembly are coaxially arranged. The first locking assemblies and the second locking assemblies are movably connected to the box body. The first part rotates under the action of external force, driving the second part to rotate in the opposite direction, so that the first locking assemblies and the second locking assemblies on one side of the transmission assembly move towards each other to release the locking. By arranging the first part and the second part, the driving force is transmitted by the reverse rotation of the two parts to flip and open the bottom plate. Compared with the traditional transmission mode, the friction in the transmission process is reduced, the stick-slip and jamming phenomena can be avoided, and the smooth opening of the bottom plate is realized.

Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a bidirectional opening armrest box cover transmission mechanism and armrest box. Background Technology

[0002] With the continuous development of automotive technology, most car models on the market today are equipped with armrest boxes or car refrigerators. In order to make it convenient for both the driver and the front passenger to access items, the top cover of the armrest box or car refrigerator adopts a two-way opening structure. This type of cover has two rotating axes, one on the left and one on the right. Each rotating axis has two rotating shafts distributed front and back. The two rotating shafts are respectively inserted into the cover so that both sides of the cover are locked to the cover. Pressing the switch on one side causes the mechanism inside the cover to use a slanted elongated hole or a slanted slider to convert the external force applied in the left and right direction into a force in the front and back direction, causing the two rotating shafts on the same side to disengage from the cover, thereby unlocking the cover. However, the slanted sliding method has a large friction, which can easily cause sticking or jamming, making it difficult to control the operating force of the opening button to a comfortable pressing range.

[0021] Example 1 As mentioned in the background section, to address the problems in the prior art, this embodiment provides a bidirectional opening armrest box cover transmission mechanism, comprising: Base plate 6; The transmission assembly has a first part 1 and a second part 2, which are slidably connected. The first part 1 is connected to two first locking assemblies 3 along a first direction, and the second part 2 is connected to two second locking assemblies 4 along the first direction. The first part 1 and the second part 2 are rotatably connected to the base plate 6 along a second direction. The first locking assemblies 3 and the second locking assemblies 4, located on the same side of the transmission assembly, are coaxially arranged along the second direction. The second direction is perpendicular to the first direction. The first locking assemblies 3 and the second locking assemblies 4 are movably connected to the housing. The first part 1 of the transmission assembly rotates under the action of external force, and the second part 2 of the transmission assembly rotates in the opposite direction under the drive of the first part 1, so that the first locking component 3 and the second locking component 4 on one side of the transmission assembly move towards each other to release the lock.

[0022] like Figure 1-12 As shown, the first direction is Figure 1 The top and bottom directions, the second direction is Figure 1 For ease of explanation, the left and right directions in the text will be... Figure 1The upper and lower sides of the base plate 6 are respectively referred to as the first side and the second side. Two rotating shafts are distributed along the second direction at the center line of the base plate 6. The first part 1 is fitted onto one of the rotating shafts and rotatably connected to the base plate 6. The second part 2 is fitted onto the other rotating shaft and is also rotatably connected to the base plate 6. The ends of the first part 1 and the second part 2 that are close to each other are rotatably and slidably connected. Two first locking components 3 are respectively disposed at both ends of the base plate 6 along the first direction. The first locking component 3 includes a first connecting plate 31 and a first shaft pin. The first connecting plate 31 is slidably connected to the base plate 6 along the second direction and is drively connected to the first part 1. The first shaft pin is fixed to one end of the first connecting plate 31 and along the second direction... The bottom plate 6 is penetrated; two second locking components 4 are respectively disposed at both ends of the bottom plate 6 along the first direction. The second locking component 4 includes a second connecting plate 41 and a second shaft pin 42. The second connecting plate 41 is slidably connected to the bottom plate 6 along the second direction and is connected to the second part for transmission. The second shaft pin 42 is fixed to one end of the second connecting plate 41 and penetrates the bottom plate 6 along the second direction. When the bottom plate 6 is fastened to the box body, the first shaft pin and the second shaft pin 42 are respectively inserted into the box body to fix the bottom plate 6 to the box body. The bottom plate 6 is hinged to the box body through the first shaft pin and the second shaft pin arranged on the same side and coaxially. A torsion spring is provided at each of the four hinge points between the bottom plate and the box body. The two ends of the torsion spring abut against the bottom plate 6 and the box body.

[0023] Initially, both the first and second axle pins 42 are inserted into the housing to fasten the base plate 6 to the housing, and an external force is applied to the first part 1 to make it move along... Figure 1 The first part 1 rotates counterclockwise, causing the second part 2 to move along... Figure 1 Rotating clockwise, under the rotation of the first part 1 and the second part 2, the first connecting plate 31 and the second connecting plate 41 on the second side slide towards each other along the second direction, and the first axle pin and the second axle pin 42 on the second side disengage from the housing. At this time, the end of the bottom plate 6 near the second side is disconnected from the housing, and under the elastic force of the torsion spring, it flips open with the first axle pin and the second axle pin 42 on the first side as the axis; an external force is applied to the first part 1 to make it rotate along... Figure 1 The first part 1 rotates clockwise, causing the second part 2 to rotate along the same direction. Figure 1 Rotating counterclockwise, under the rotation of the first part 1 and the second part 2, the first connecting plate 31 and the second connecting plate 41 on the first side slide towards each other in the second direction, and the first shaft pin and the second shaft pin 42 on the first side are dislodged from the box. At this time, the end of the bottom plate 6 near the first side is disconnected from the box, and under the elastic force of the torsion spring, it flips open with the first shaft pin and the second shaft pin 42 on the second side as the axis.

[0024] By setting up a first part 1 and a second part 2, when the first part 1 rotates, it drives the second part 2 to rotate in the opposite direction, thereby causing the first locking component 3 and the second locking component 4 on the same side to move towards each other and disengage from the box. The bottom plate 6 flips around the first locking component 3 and the second locking component 4 on the other side to open. Compared with the traditional inclined plane sliding transmission method, the friction during the transmission process is reduced, which can effectively avoid sticking and jamming. The rotation of the first part 1 and the second part 2 helps to better control the force required to unlock the bottom plate 6, so as to achieve smooth opening of the bottom plate 6.

[0025] Furthermore, the first part 1 has first connecting holes 11 at both ends along the first direction, and the first locking assembly 3 has a second pin 311 corresponding to the first connecting hole 11. The second pin 311 abuts against the inner wall of the first connecting hole 11 away from the second locking assembly 4, and there is a gap between the second pin 311 and the inner wall of the first connecting hole 11 away from the second locking assembly 4.

[0026] The second part 2 is provided with third pins 21 at both ends along the first direction. The second locking assembly 4 is provided with a second connecting hole 411 corresponding to the third pin 21. The third pin 21 abuts against the inner wall of the second connecting hole 411 on the side close to the first locking assembly 3, and there is a gap between the third pin 21 and the inner wall of the second connecting hole 411 on the side away from the first locking assembly 3.

[0027] For details, please refer to Figure 10-12 The two first connecting plates 31 are positioned higher than the first part 1 in the vertical direction. The shape of the first connecting hole 11 is approximately a rounded rectangular hole. The second pin 311 is disposed on the first connecting plate 31. The second pin 311 extends downward in the vertical direction and passes through the first connecting hole 11. There is also a gap between the second pin 311 and the inner walls of the first connecting hole 11 on both sides in the second direction. When the first part 1 moves along... Figure 1 When the first part 1 rotates counterclockwise, it interacts with the second pin 311 on the second side, causing the first connecting plate 31 on the second side to move along the second direction towards the side closer to the second connecting plate 41. During this process, the second pin 311 on the first side does not contact the first part 1, therefore the first connecting plate 31 on the first side does not move. When the first part 1 rotates counterclockwise... Figure 1 When the first part 1 rotates clockwise, it drives the first connecting plate 31 on the first side to move along the second direction towards the side closer to the second connecting plate 41 by acting with the second pin 311 on the first side. The second pin 311 on the second side does not come into contact with the first part 1 during the above process, so the first connecting plate 31 on the second side does not move. The two second connecting plates 41 are positioned higher than the second part 2 in the vertical direction. The shape of the second connecting hole 411 is also approximately a rounded rectangular hole. The third pin 21 is disposed on the second part 2, extending upward in the vertical direction and passing through the second connecting hole 411. There is also a gap between the third pin 21 and the inner walls of the second connecting hole 411 on both sides along the second direction. When the second part 2 moves along... Figure 1 When the second part 2 rotates clockwise, it interacts with the third pin 21 on the second side, causing the second connecting plate 41 on the second side to move towards the side closer to the first connecting plate 31 along the second direction. During this process, the second connecting plate 41 on the first side does not come into contact with the third pin 21, therefore the second connecting plate 41 on the first side does not displace. When the second part 2 rotates clockwise... Figure 1 When the second part 2 rotates counterclockwise, it drives the second connecting plate 41 on the first side to move along the second direction toward the side closer to the first connecting plate 31 by acting with the third pin 21 on the first side. The second connecting plate 41 on the second side does not come into contact with the third pin 21 during the above process, so the second connecting plate 41 on the second side does not displace.

[0028] In addition, it should be noted that the positions of the second pin 311 and the first connecting hole 11, and the third pin 21 and the second connecting hole 411 can be interchanged, as long as the first part 1 and the first connecting plate 31 and the second part 2 and the second connecting plate 41 achieve clearance fit.

[0029] Furthermore, Two first slide rails 76 are symmetrically provided on the base plate 6 along the first direction, and the first locking component 3 slides within the first slide rails 76. Two second slide rails 77 are symmetrically provided on the base plate 6 along the first direction, and the second locking assembly 4 slides within the second slide rails 77.

[0030] For details, please refer to Figure 5 The first slide 76 extends along the second direction, and the first connecting plate 31 is provided with a first slider. The first slider is embedded in the first slide 76 so that the first connecting plate 31 is slidably connected to the base plate 6. The second slide 77 also extends along the second direction, and the second connecting plate 41 is provided with a second slider. The second slider is embedded in the second slide 77 so that the second connecting plate 41 is slidably connected to the base plate 6.

[0031] In a preferred embodiment, The first part 1 is provided with a connecting shaft 12; The second part 2 has a strip hole 22 corresponding to the connecting shaft 12, and the strip hole 22 extends along the second direction; The connecting shaft 12 is located inside the strip hole 22. When the first part 1 rotates, the connecting shaft 12 rotates and slides relative to the strip hole 22, thereby driving the second part 2 to rotate.

[0032] like Figure 7 and Figure 9 As shown, the first part 1 is positioned lower than the second part 2 in the vertical direction. The connecting shaft 12 is located at one end of the first part 1 near the second part 2 and extends vertically upward through the slot 22. When the connecting shaft 12 rotates with the first part 1, it rotates and slides relative to the second part 2, thereby causing the second part 2 to rotate in the opposite direction.

[0033] In a preferred embodiment, A first elastic element 71 is provided between the first locking assembly 3 and the base plate 6, and a second elastic element 72 is provided between the second locking assembly 4 and the base plate 6. When the external force is removed, the first locking assembly 3 and the first part 1 are reset under the elastic force of the first elastic member 71; the second locking assembly 4 and the second part 2 are reset under the elastic force of the second elastic member 72.

[0034] like Figure 2 As shown, both the first elastic element 71 and the second elastic element 72 are springs in the prior art. A first through hole is provided on the first connecting plate 31, and a first protrusion is provided inside the first through hole. A first fixing part 701 is provided on the base plate 6 corresponding to the first through hole, and the first fixing part 701 is located inside the first through hole. The first elastic element 71 is disposed in the first through hole along a second direction, and its two ends abut against the first protrusion and the first fixing part 701 respectively. The first connecting plate 31 abuts against the first fixing part 701 under the elastic force of the first elastic element 71. A second through hole is provided on the second connecting plate 41, and a second protrusion is provided inside the second through hole. A second fixing part is provided on the base plate 6 corresponding to the second through hole. Part 702, the second fixing part 702 is located in the second through hole, the second elastic member 72 is disposed in the second through hole along the second direction and its two ends abut against the second protrusion and the second fixing part 702 respectively, and the second connecting plate 41 abuts against the second fixing part 702 under the elastic force of the second elastic member 72; when the first part 1 and the second part 2 rotate under the action of external force, driving the first connecting plate 31 and the second connecting plate 41 on one side to move towards each other, the first elastic member 71 and the second elastic member 72 on one side are compressed; when the external force is removed, the first connecting plate 31 and the second connecting plate 41 are reset under the action of the first elastic member 71 and the second elastic member 72 respectively.

[0035] In a preferred embodiment, it further includes: two switch components 5; the two switch components 5 are distributed on the base plate 6 along a first direction.

[0036] Under the action of external force, the switch assembly 5 slides along the first direction and abuts against the first part 1, so that the first part 1 and the second part 2 rotate in opposite directions, thereby causing the first locking assembly 3 and the second locking assembly 4 on the same side as the switch assembly 5 to move towards each other.

[0037] like Figure 1 As shown, two switch assemblies 5 are respectively disposed on the first side and the second side of the base plate 6, and are slidably connected to the base plate 6; when an external force is applied to the switch assembly 5 on the first side, the switch assembly 5 on the first side slides towards the second side, and pushes the first part 1 along... Figure 1 Rotate clockwise in the middle, the second part 2 along Figure 1 When rotated counterclockwise, the first locking assembly 3 and the second locking assembly 4 on the first side move towards each other; when an external force is applied to the switch assembly 5 on the second side, the switch assembly 5 on the second side slides towards the first side and pushes the first part 1 along... Figure 1 Rotate counterclockwise in the middle, the second part 2 along Figure 1 When rotated clockwise, the first locking component 3 and the second locking component 4 on the second side move toward each other.

[0038] Furthermore, the switch assembly 5 includes: Push plate 51 is slidably connected to base plate 6; The third elastic element 73 is disposed between the push plate 51 and the bottom plate 6; Button 52, one end of button 52 abuts against push plate 51; In this process, the button 52 drives the push plate 51 to slide on the base plate 6 under the action of external force, so that the first part 1 and the second part 2 rotate in opposite directions; when the external force is removed, the push plate 51 and the button 52 are reset under the action of the elastic force of the third elastic member 73.

[0039] For details, please refer to Figure 2Two third slides are symmetrically arranged on the base plate 6 along the first direction. The third slides extend along the first direction. A third slider is provided on the push plate 51 and is embedded in the third slide, so that the push plate 51 is slidably connected to the base plate 6. The two push plates 51 are respectively provided with third protrusions at their close ends. A third fixing part 703 is provided on the base plate 6 corresponding to the third protrusions. The two ends of the third elastic member 73 abut against the third protrusions and the base plate 6 respectively, so that the push plate 51 is elastically connected to the base plate 6. Two buttons 52 are symmetrically arranged along the first direction. One end of button 52 abuts against push plate 51. Button 52 is also provided with limiting claw 521. Limiting claw 521 is used to engage with base plate 6 under the elastic force of third elastic element 73 to prevent button 52 from coming off base plate 6. With the above settings, the first elastic element 71, the second elastic element 72 and the third elastic element 73 do not interfere with each other during compression and release. In the design, there is no need to consider the relationship between the superposition or cancellation of the elastic forces of each elastic element, which makes it easy to control the operating force when opening to a comfortable pressing range.

[0040] Furthermore, The first part 1 is provided with two grooves symmetrically along the first direction; A first pin 511 is provided on the corresponding groove of the switch assembly 5; When the switch assembly 5 slides along the first direction, it drives the first part 1 to rotate through the first pin 511.

[0041] For details, please refer to Figure 7 The push plate 51 is positioned lower than the first part 1 in the vertical direction. The two first pins 511 are respectively set in the two grooves and extend in the vertical direction. The two first pins 511 are located on the same side of the rotation axis of the first part 1 along the second direction. When the button 52 is pushed in the first direction, the first pins 511 abut against the first part 1 and drive the first part 1 and the second part 2 to rotate in opposite directions.

[0042] In a preferred embodiment, the base plate 6 is provided with a first arc-shaped slide rail and a second arc-shaped slide rail, the first part 1 is slidably engaged with the first arc-shaped slide rail, and the second part 2 is slidably engaged with the second arc-shaped slide rail.

[0043] like Figure 5As shown, the base plate 6 is provided with multiple first claws 74, which are divided into two groups. One group of first claws 74 is distributed along the circumference in a first arc-shaped trajectory, and the other group of first claws 74 is distributed along the circumference in a second arc-shaped trajectory. The center of the second arc-shaped trajectory and the center of the first arc-shaped trajectory are located on the rotation axis of the first part 1, and the radius of the second arc-shaped trajectory is larger than that of the first arc-shaped trajectory. Thus, the two groups of first claws 74 together form a first arc-shaped slide. The first part 1 is provided with a first fan-shaped hole 13. The multiple first claws 74 pass through the first fan-shaped hole 13 in the vertical direction and abut against the first part 1. When the first part 1 rotates in the circumference direction, it slides in contact with the first claws 74. The first claws 74 are used to limit the rotation trajectory of the first part 1. The base plate 6 is also provided with multiple second claws 75, which are divided into two groups. One group of second claws 75 is distributed along the circumference in a third arc-shaped trajectory, and the other group of second claws 75 is distributed along the circumference in a fourth arc-shaped trajectory. The center of the fourth arc-shaped trajectory and the third arc-shaped trajectory are located on the rotation axis of the second part 2, and the radius of the fourth arc-shaped trajectory is larger than that of the third arc-shaped trajectory. Thus, the two groups of second claws 75 together form a second arc-shaped slide. The second part 2 is provided with a second fan-shaped hole 23. Multiple second claws 75 pass through the second fan-shaped hole 23 in the vertical direction and abut against the second part 2. When the second part 2 rotates in the circumference direction, it slides in contact with the second claws 75. The second claws 75 are used to limit the rotation trajectory of the second part 2.

[0044] In a preferred embodiment, magnets 101 are respectively provided on the first locking component 3, the second locking component 4 and the base plate 6; When the external force is removed, the end of the first locking component 3 near the bottom plate 6 and the end of the second locking component 4 near the bottom plate 6 are locked to the box under the action of magnetic force.

[0045] like Figure 12 As shown, when the base plate 6 is fastened to the housing, the first connecting plate 31 and the second connecting plate 41 are relatively fixed to the base plate 6 in the second direction only by the elastic force of the first elastic member 71. In order to avoid collision noise between the first connecting plate 31 and the second connecting plate 41 and the base plate 6 due to vibration during vehicle operation, magnets 101 are respectively provided on the first connecting plate 31, the second connecting plate 41 and the base plate 6 at the positions corresponding to the first connecting plate 31 and the second connecting plate 41. The end of the first connecting plate 31 near the base plate 6 is attached to the base plate 6 under the action of magnetic force, and the end of the second connecting plate 41 near the base plate 6 is attached to the base plate 6 under the action of magnetic force, thereby avoiding the generation of abnormal noise.

[0046] In a preferred embodiment, both the second pin 311 and the third pin 21 are covered with a buffer layer 102.

[0047] like Figure 10 and Figure 11 As shown, the buffer layer 102 can be made of flexible materials such as rubber or silicone, and is used to cover the outer periphery of the second pin 311 and the third pin 21 to prevent collision noises between the second pin 311 and the first part 1, the third pin 21 and the second connecting plate 41.

[0048] Working principle: Initially, the base plate 6 is fastened to the box body. When it is necessary to open from the first side, press the button 52 on the first side. The button 52 drives the push plate 51 to move along the first direction. The push plate 51 pushes the first part 1 along the first pin 511. Figure 1 When the first part 1 rotates clockwise, it simultaneously drives the second part 2 to rotate in the opposite direction. The end of the first part 1 near the first side acts on the first connecting plate 31 through the second pin 311, causing the first connecting plate 31 to move towards the second connecting plate 41 in the second direction. The third pin 21 of the second part 2 near the first side acts on the second connecting plate 41, causing the second connecting plate 41 to move towards the first connecting plate 31 in the second direction. The first axle pin and the second axle pin 42 on the first side are disengaged from the housing. At this time, the end of the bottom plate 6 near the first side is disconnected from the housing and flips open with the first axle pin and the second axle pin 42 on the second side as the axis under the elastic force of the torsion spring. When it needs to be opened from the second side, press the button 52 on the second side. The button 52 drives the push plate 51 to move along the first direction. The push plate 51 pushes the first part 1 along the first pin 511. Figure 1 The first part 1 rotates counterclockwise, simultaneously causing the second part 2 to rotate in the opposite direction. The end of the first part 1 near the second side acts on the first connecting plate 31 through the second pin 311, causing the first connecting plate 31 to move towards the second connecting plate 41 in the second direction. The third pin 21 of the second part 2 near the second side acts on the second connecting plate 41, causing the second connecting plate 41 to move towards the first connecting plate 31 in the second direction. The first axle pin and the second axle pin 42 on the second side are disengaged from the housing. At this time, the end of the bottom plate 6 near the second side is disconnected from the housing and flips open under the elastic force of the torsion spring, using the first axle pin and the second axle pin 42 on the first side as the axis.
