Description

Technical Field

[0001] The invention belongs to the field of automobile intelligent cockpit, and specifically, is a design for fully automatic deployment and retraction of automobile airbag beds. Background Art

[0002] In today's world of rapid technological development, cars are playing an increasingly important role in people's production and life. With the rapid development of automobile electrification and communication technology, remote one-click control of cars through mobile phone software has become a standard configuration for more and more cars, and automobile automation capabilities have enabled more and more car functions to be realized.

[0003] With the acceleration of people's pace of life and the increase of various lifestyles such as outdoor parades, people's demand for sleeping in the car is gradually increasing. Due to the low width and poor comfort of the car's internal seats, airbag mattresses that match the space in the car are gradually becoming the choice of more and more people. However, in previous designs, car owners often need to place and inflate the airbag mattress in the car, and after sleeping, they need to deflate the airbag mattress and roll it up manually. The whole process wastes a lot of time and energy, greatly limiting the application scenarios of sleeping on the airbag bed in the car.

[0004] The existing technology can often only realize the automatic deployment of the air bed, but cannot realize automatic retraction, and its degree of automation is low, and generally only the rear seats can be folded down, resulting in the air bed being often short in length, making it unsuitable for tall people and having low comfort. Summary of the invention

[0005] Purpose of the invention: In view of the above shortcomings, the present invention provides a design for fully automatic deployment and retraction of automobile airbag beds.

[0006] Technical solution: In this design, the front headrest of the car is automatically rotated to the bottom of the seat through the automatic rotation mechanism, and the automatically retractable airbag module is placed on the back of the rear seat of the car, which can realize the fully automatic deployment and storage of the airbag bed in the car with one click, and no human intervention is required throughout the process. In the process of seat-to-bed transformation, that is, airbag bed deployment, the front seat headrest is first rotated to the seat back through the automatic rotation mechanism, and the whole is laid flat backward and connected to the rear seat, and the backrest of the rear seat is rotated forward and laid flat, and then the air mattress protective cover is opened, and the telescopic rod inside the airbag bed is extended forward and backward. When it is fully extended, the air pump is turned on and the mattress is opened as a whole. In the process of bed-to-seat transformation, that is, airbag bed contraction, the airbag bed deflation port is opened, the mattress is deflated, and then the telescopic rod inside the airbag is shortened, and the airbag mattress is controlled to contract backward, and then the airbag dust cover is closed, and the seat is restored to its original position. This design does not require manual intervention throughout the process, and can realize one-click fully automatic seat folding and airbag bed deployment and one-click airbag bed retraction and seat reset through remote control.

[0007] Beneficial effects: This design does not require manual intervention throughout the process. It can realize one-button fully automatic seat folding and air cushion bed deployment and one-button air cushion bed retraction and seat reset through remote control. Therefore, it can effectively reduce the time and energy spent by the owner in the whole process. With only one-button remote design, the car's electrical components can fully automatically realize the deployment and retraction of the car airbag bed, greatly increasing people's willingness to use airbag mattresses and expanding their usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1-6 Shown is a schematic diagram of the process of unfolding the automobile airbag bed of the present invention. Figure 7-11 Shown is a schematic diagram of the process of retracting the automobile airbag bed of the present invention. Fig.12 Shown is a schematic diagram of the telescopic rod of the automobile airbag bed of the present invention in the retracted state. Fig.13 Shown is a schematic diagram of the telescopic rod of the automobile airbag bed of the present invention in the unfolded state. DETAILED DESCRIPTION

[0009] The design steps are as follows. The airbag bed deployment process is divided into five steps. In the first step, the fully automatic seat headrest is automatically moved to the back of the seat back through the joint control of the internal automatic motor and the connecting rod, and the maximum height of the headrest is lower than the seat back. Figure 1-2 Step 2: Fold the front seat back to the same height as the rear seat cushion, and fold the rear seat back completely forward. Figure 3 Step 3: Rotate the air mattress cover backwards to open it. Figure 4 As shown, during the opening process, it is also possible to effectively check whether there are any debris in the trunk space where the protective cover rotates that prevents the protective cover from fully opening. If there are any debris, the fully automatic air bed opening process can be stopped in time and the owner can be notified through a mobile phone message that the opening failed due to insufficient trunk space, and the original state of the car will be automatically restored. Step 4: The telescopic rods connected at both ends of the air bed are extended to allow the airbag to be deployed as a whole, as shown in the figure. Figure 6 The schematic diagram of the telescopic rod of the car airbag bed in the retracted and opened state is as shown in Figure 12-13 During the opening process, you can also effectively check whether there are any debris on the seat cushion that prevents the telescopic rod from fully extending. If there is, you can stop the opening process of the fully automatic air bed in time and notify the owner through a mobile phone message that the opening failed due to the object on the seat cushion, and automatically restore the original state of the car. Step 5: When the air bed is fully extended, the air pump is powered on, and the airbag is fully propped up. Figure 7 At this point, the airbag bed deployment process is completely completed. The airbag bed retraction process is divided into five steps. The first step is to reverse the air pump motor to discharge the air in the airbag. Figure 7 As shown. In the second step, the telescopic rods at both ends of the airbag are contracted to shrink the airbag, as shown in FIG. Figure 8 The third step is to reset the airbag protection cover and wrap the airbag on the back of the seat cushion. Fig. 9Step 4: The front seat backrest rotates forward to reset, and the rear seat backrest rotates backward to automatically reset. Fig.10 As shown. Step 5, the fully automatic seat headrest is automatically reset through the joint control of the internal automatic motor and the connecting rod. At this time, the airbag bed retraction process is completely completed.
