With the progress of society and the development of technology, the demand of automobile passengers is becoming more and more diversified along with the diversification of work and life. Due to the increasing popularization of the automobile, the automobile is gradually inseparable with the life of people. More and more people not only pursue the function realization of the automobile as a vehicle, but also put higher demands on the riding environment. For the limited space inside the vehicle, how to build a comfortable, tidy and unobtrusive riding environment becomes the goal pursued by the vehicle enterprises at present.

For the existing storage device in the vehicle space, the defect that the function is single and fixed is generally overcome. For example: although some vehicles are provided with fixed cup holders on armrest boxes to accommodate beverage cups or water cups, the fixed cup holders inevitably occupy more space in the vehicle, and the fixed cup holders are fixed in structure, can only accommodate beverage cups or water cups with fixed sizes, and cannot flexibly adapt to beverage cups or water cups with different sizes. In addition, the fixed cup stand additionally occupies the space in the armrest box, and the space utilization rate is not improved.

Another example is: along with the increase of the use frequency of the mobile phone, more and more people set the mobile phone supports in the car, however, the set mobile phone supports also need to additionally occupy the space in the car, and the space utilization rate is not favorable to be improved. Meanwhile, the arranged mobile phone support cannot be accommodated in a closed space, and potential safety hazards such as head touch or mobile phone separation can be caused once emergency braking occurs.

Based on this, in order to satisfy various requirements for the interior space of the vehicle, especially to the space utilization and the higher demand of taking comfort, meanwhile, in view of the consideration of the ease of use of the vehicle product by the vehicle passengers, it is desirable to obtain a bracket which can realize the switching under different working states, can clamp different articles, and can be accommodated in the accommodating space when not in use.

In addition, in some embodiments, a rack 112 may be further disposed on the housing 11, the rack 112 is disposed to be matched with the gear 111 disposed on the clamping mechanism assembly 12, wherein a length direction of the rack 112 is consistent with a linear moving direction of the clamping mechanism assembly 12 into and out of the housing 11, so as to ensure that the clamping mechanism assembly 12 can move linearly, and meanwhile, friction force when the housing 11 and the clamping mechanism assembly 12 move relatively is also reduced, so that the relative movement is smoother, and the clamping mechanism assembly 12 is not easily damaged.

Of course, in some other embodiments, the gear 111 may be disposed on the housing 11, and the rack 112 may be disposed on the clamping mechanism assembly 12; alternatively, the gear and rack structure may not be provided.

As can be seen in conjunction with fig. 1 and 5, labyrinth lock rotary 15 is hinged to housing 11 at hinge point 154. As further shown in fig. 5, the labyrinth lock rotating member 15 is provided with a plurality of protrusions 152 to form a traveling passage 153 for the labyrinth lock 123 (the labyrinth lock 123 may refer to fig. 6) to pass through, a slot 151 for the labyrinth lock 123 to be engaged, and an intermediate stopper 155 on the labyrinth lock rotating member 15.

As shown in fig. 6, the clamping mechanism assembly 12 includes a first clamping structure 121, a second clamping structure 122, and a labyrinth lock 123. The labyrinth lock 123 may be provided in a trapezoidal shape. Of course, in some other embodiments, the labyrinth lock may be shaped in other shapes, such as a parallelogram.

As can be seen from fig. 1 and 6, Y-rails 171 and Z-rails 172 are disposed between the clamping mechanism assembly 12 and the housing 11. The length directions of the Y-direction slide rails 171 and the Z-direction slide rails 172 are the same as the linear moving direction of the clamping mechanism assembly 12 entering and exiting the housing 11, the Y-direction slide rails 171 are arranged in pairs along the width direction of the clamping mechanism assembly 12 or the housing 11 to prevent the clamping mechanism assembly 12 from shaking along the width direction in the moving process, and the Z-direction slide rails 172 are arranged in pairs along the height direction of the clamping mechanism assembly 12 or the housing 11 to prevent the clamping mechanism assembly 12 from shaking along the height direction in the moving process.

Fig. 7 is a schematic view of the retractable stand of the present invention with the resilient members of some embodiments disposed on the clamping mechanism assembly. FIG. 8 is a schematic diagram of the structure of the elastic component of the stowable support of the invention in some embodiments.

Referring to fig. 1 and 6, in conjunction with fig. 7 and 8, and as necessary, in certain embodiments, a resilient member 16 is provided between the clamping mechanism assembly 12 and the housing 11, the resilient member 16 being for continuously applying a return spring force to the clamping mechanism assembly 12 that is intended to push the clamping mechanism assembly 12 out of the housing 11. The elastic component 16 may include a furling spring 161, wherein one end of the furling spring 161 is provided with a spring slot 163, so as to clamp one end of the furling spring 161 on the housing 11, while the other end of the furling spring 161 is connected to a spring push rod 162, and the spring push rod 162 is erected on the clamping mechanism assembly 12, so that the furling spring 161 always tends to roll back toward the spring slot 163, and further, there is a pushing force of the spring push rod 162 moving toward the spring slot 163.

As can be seen in connection with fig. 6 and 9, the second clamping structure 122 may be configured as a cup holder clamping structure. The second clamping structure 122 may include arc-shaped cantilevers 1221 arranged in pairs, a fixed bracket 1222, and a control spring 1223 disposed between the fixed bracket 1222 and each of the arc-shaped cantilevers 1221. Wherein, the arc cantilever 1221 that sets up in pairs can be opened relatively under the exogenic action, and when removing exogenic action, the arc cantilever 1221 that sets up in pairs closes relatively under control spring 1223's elasticity effect. Bolts may be used to pass through the mounting holes 1224 of the mounting bracket 1222 to mount the second clamp structure 122 to the clamp mechanism assembly 12.

Through the structure, the second clamping structure 122 in the present application can easily clamp beverage bottles or water cups with different sizes. When clamping is needed, the arc-shaped cantilever 1221 is firstly opened, the opening degree of the opening is determined according to the size, and then a beverage bottle or a water cup is placed in the accommodating space formed by the arc-shaped cantilever 1221. The arc-shaped cantilever 1221 is loosened, and the arc-shaped cantilever 1221 clamps the beverage bottle or the water cup under the elastic force of the control spring 1223, so that the beverage bottle or the water cup is clamped and cannot be toppled.

Reference may be made to fig. 10-12 for a preferred structural arrangement of the first clamp structure under certain embodiments.

Fig. 10 schematically illustrates the structure of a first clamping structure of a stowable stand according to the invention in some embodiments. Fig. 11 schematically illustrates the configuration of a clamping assembly of the stowable stand of the invention in one station, in some embodiments. Fig. 12 schematically illustrates the configuration of a clamping assembly of the stowable stand according to the invention in another position, in some embodiments.

As shown in fig. 10, the first clamping structure 121 disposed on the clamping mechanism assembly 12 may be configured as a handset clamping structure, the first clamping structure 121 includes a fixing frame 1211 and a clamping component 124, and the fixing frame 1211 and the clamping component 124 together form an accommodating space. In addition, considering that the holder is a mobile phone, a preformed hole 1212 may be formed on a bottom surface of the accommodating space formed by the fixing frame 1211 and the clamping assembly 124, so that a data line or a charging line of the mobile phone may pass through the preformed hole 1212 to be connected to the mobile phone.

As can be seen in conjunction with fig. 11 and 12, the clamping assembly 124 may include: a fixed block 1241, an intermediate movable block 1242 and a clamping jaw 1243. Here, the fixing block 1241 is fixed to the end cover 13 by passing a screw through a screw fixing hole 1246 of the fixing block 1241. The intermediate movable block 1242 is slidably connected with the fixed block 1241 to linearly move in a width direction of the first clamp structure 121, so that the intermediate movable block 1242 can be opened or closed with respect to the fixed block 1241. And the clamping jaw 1243 has a hook-shaped jaw portion, and the clamping jaw 1243 is slidably coupled with the intermediate movable block 1242 to linearly move in the width direction of the first clamping structure 121, thereby enabling the clamping jaw 1243 to be opened or closed with respect to the intermediate movable block 1242.

A first elastic member 1244 is connected between the fixed block 1241 and the intermediate movable block 1242, and the first elastic member 1244 is configured to apply an elastic force to the intermediate movable block 1242 to close it with respect to the fixed block 1241. A second elastic member 1245 is connected between the intermediate movable block 1242 and the clamping jaw 1243, and the second elastic member 1245 is configured to apply an elastic force to the clamping jaw 1243 to close it with respect to the intermediate movable block 1242.

In some embodiments, each of the first elastic component 1244 and the second elastic component 1245 may include: a spring and a spring rod connected with the spring.

When the width of the mobile phone is small, the mobile phone can be directly placed in the accommodating space formed by the first clamping structure 121 as shown in fig. 10, and at this time, the first clamping structure is at the working position shown in fig. 11, that is, the middle movable block 1242 is closed relative to the fixed block 1241, and the clamping jaws 1243 are also closed relative to the middle movable block 1242. When the mobile phone has a large width, as shown in fig. 12, the clamping assembly 124 is opened by an external force, and at this time, the first elastic assembly 1244 and/or the second elastic assembly 1245 is extended out of the hole by the external force, so that the middle movable block 1242 is opened with respect to the fixed block 1241, or/and the clamping claw 1243 is opened with respect to the middle movable block 1242, and at this time, the accommodating space formed by the clamping assembly 124 and the fixed block 1211 is enlarged, so that the mobile phone with a large size can be placed in the accommodating space, and after the external force is removed, the middle movable block 1242 and/or the clamping claw 1243 is moved in the elastic force returning direction by the elastic force of the first elastic assembly 1244 and/or the second elastic assembly 1245, so as to firmly clamp and fix the mobile phone.

Fig. 13 to 15 illustrate the configuration of the stowable support in different stations.

Fig. 13 schematically illustrates a stowable stand configuration of the invention in a fully open position in some embodiments. As shown in fig. 13, when the stowable stand 1 is in the fully open position, both the first and

second clamp structures

121 and 122 protrude from the housing 11 as described above.

Fig. 14 schematically illustrates a stowable stand configuration of the invention in an intermediate open position in some embodiments. As shown in fig. 14, when the stowable stand 1 is in the intermediate open position, the first clamping mechanism 121 protrudes from the housing 11 described above, while the second clamping mechanism 122 remains housed within the housing 11.

FIG. 15 schematically illustrates a stowable stand configuration of the invention in a fully closed position in some embodiments. As shown in fig. 15, when the stowable stand 1 is in the fully closed position, the first and

second clamping structures

121 and 122 described above are fully accommodated within the housing 11 described above.

Reference may be further made to fig. 16 to 24 as to the working principle and procedure of how the present stowable stand 1 enables switching between different work stations.

As shown in fig. 16, the stowable stand 1 at the fully closed position is pressed with an external pushing force F1, so that the press lock module body 142 releases the press lock module push rod 141. When the external pushing force F1 is removed, the restoring elastic force F2 generated by the elastic member 16 makes the labyrinth lock piece 123 move in the first moving path 1531 toward the first direction V1 from the initial position shown in fig. 16 until being stopped by the intermediate stopper 155.

Subsequently, as shown in fig. 17, the labyrinth lock 123 continues to travel in the first direction V1, and generates an interaction force with the first guide slope I provided on the outer wall of the intermediate stopper 155, which causes the labyrinth lock rotary member 15 to also rotate about the hinge point 154 in the first rotation direction W1 until the labyrinth lock 123 moves to be stopped by the second guide slope II of the protrusion 152.

Since the return spring force F2 generated by the elastic member 16 still exists, under the action of the return spring force F2, the labyrinth lock piece 123 continues to travel along the first direction V1 and generates an interaction force between the labyrinth lock piece and the second guide slope II of the protrusion 152, and the interaction force generated by the movement process causes the labyrinth lock rotary piece 15 to rotate around the hinge point 154 in the second rotation direction W2 as shown in fig. 18. As such, travel of the labyrinth lock 123 in the first direction causes the clamping mechanism assembly 12 to reach the fully open station.

The starting position of labyrinth rotator 15 and labyrinth lock 123 when stowable rack 1 is in the fully open position can be seen in fig. 18. When the station is switched, the end cover 13 is pressed to apply the external pushing force F1 to the stowable bracket 1 again. At this time, the labyrinth lock 123 moves in the second direction retracted into the housing 11 as shown in fig. 19, and during the movement, the labyrinth lock 123 moves in the second moving passage 1532 in the second direction V2 first by the external pushing force F1 until the labyrinth lock 123 moves to the intermediate stopper 155 and is stopped by the intermediate stopper.

Subsequently, due to the action of the external thrust F1, the labyrinth lock 123 continues to move in the second direction V2, as shown in fig. 20: the labyrinth lock 123 moves along the third guiding slope III of the intermediate block 155, and at the same time, the labyrinth lock rotary member 15 rotates around the hinge point 154 in the second rotation direction W2 due to the interaction force between the labyrinth lock 123 and the intermediate block 155 during the movement until the labyrinth lock 123 completely falls into the groove of the intermediate block 155.

At this time, the external pushing force F1 is removed, and as shown in fig. 21, the restoring elastic force F2 generated by the elastic member 16 moves the labyrinth lock piece 123 toward the first direction V1 until the labyrinth lock piece 123 is caught by the inner wall of the catching groove 151.

Then, as shown in fig. 22, the restoring elastic force F2 generated by the elastic member 16 makes the labyrinth lock piece 123 continue to move along the fourth guiding inclined surface IV on the inner wall of the slot 151 toward the first direction V1 until the labyrinth lock piece 123 is locked in the slot 151. In the process, the interaction force between the labyrinth lock piece 123 and the fourth guide slope IV of the card slot 151 causes the labyrinth lock rotary piece 15 to continue to rotate in the second rotation direction W2 about the hinge point 154. As such, the stowable stand 1 is switched to the intermediate open position.

The starting position of the labyrinth rotating member 15 and the labyrinth lock 123 when the stowable stand 1 is in the intermediate open position can be seen in fig. 22. As shown in fig. 23, when switching from the intermediate opening station to the fully closing station, the labyrinth lock piece 123 travels in the third travel passage 1533 in the second direction V2 by the action of the applied external pushing force F1 until the labyrinth lock piece 123 moves to the fifth guide slope V on the boss portion 152.

As shown in fig. 24, at this time, under the action of the external pushing force F1, the labyrinth lock piece 123 continues to move along the fifth guide slope V on the boss 152 in the second direction V2, and in the process, the interaction force between the labyrinth lock piece 123 and the fifth guide slope V causes the labyrinth lock rotary piece 15 to rotate around the hinge point 154 in the first rotating direction W1. Then, as the external pushing force F1 is continuously applied, the labyrinth lock piece 123 continues to move in the second direction V2 until the push-down-lock-module push rod contacts and applies a pressure to the push-down-lock-module main body, and the push-down-lock-module main body 142 is pressed by the push-down-lock-module push rod 141 to lock the push-down-lock-module push rod 141 again, so that the stowable stand 1 is at the fully closed position again.

In conclusion, the foldable support is convenient to operate, can realize free and convenient multi-station switching, and can clamp different articles at different stations. In addition, the foldable support can be also folded when not in use and is folded in the accommodating space, so that the potential safety hazard of personnel collision is avoided, and meanwhile, parts can be prevented from being damaged.
