[0039] Generally speaking, storage boxes are provided on vehicles. There is a storage space inside the storage box, and the storage space can be used to place items, thus facilitating the vehicle to store items. The items in the storage space include large luggage and some small sundries. During the driving process of the vehicle, these luggage or sundries may collide with the storage box, causing damage to the storage box. At the same time, when the luggage or sundries collide with the storage box, vibrations and noises may be generated, resulting in poor NVH performance of the vehicle and a bad riding experience.

[0040] The utility model provides a vehicle article fixing device, which is arranged in the storage box. Through the vehicle article fixing device, large luggage and small sundries can be fixed to prevent them from shaking and moving in the storage box. Specifically, the vehicle article fixing device includes an abutting part, and the abutting part is located in the storage box. The abutting part is attached to the outer surface of the article to press the article tightly against the inner wall surface of the storage box. The abutting part can be applicable to articles of various sizes and shapes, preventing the articles from shaking in the storage box when the vehicle starts or brakes, which is beneficial to protecting the storage box and reducing vibrations and noises during driving.

[0041] The following takes a feasible implementation scheme as an example to illustrate the vehicle article fixing device in the utility model.

[0042] As Figures 1 - 3 shown, this embodiment provides a solution for fixing an article 20 in a storage box 10 by using an airbag 100 and a gas supply mechanism. Specifically, the airbag 100 is made of a flexible material. The airbag 100 is located in the storage space 13 of the storage box 10. A cavity 101 is formed inside the airbag 100. The gas supply mechanism is arranged outside the storage box 10 and is communicated with the cavity 101. The gas supply mechanism can fill gas into the cavity 101 of the airbag 100. After the gas is filled, the airbag 100 is attached to the outer surface of the article 20 to fix the article 20 in the storage box 10. Since the airbag 100 is made of a flexible material, regardless of the shape of the article 20, the airbag 100 can be attached to the outer surface of the article 20, so that the article is fixed in the storage box 10 by the pressure of the gas in the cavity 101 of the airbag 100.

[0043] Exemplarily, the airbag 100 in this embodiment can be disposed on one of the inner wall surfaces of the storage box 10. For example, the storage box 10 includes a placement groove 11 and a lid 12, and the placement groove 11 and the lid 12 enclose a storage space 13. The airbag 100 is received inside the lid 12 of the storage box 10, and the article is placed at the bottom of the placement groove 11. After the cavity 101 of the airbag 100 is filled with gas, the airbag 100 extends towards the bottom of the placement groove 11 until the airbag 100 fills the storage space 13. The surface of the airbag 100 facing the article 20 closely adheres to the outer surface of the article 20 and presses the article 20 against the groove body of the placement groove 11. Since the airbag 100 will fill the space in the storage space 13 except for the article 20, the surface of the airbag 100 facing the article 20 generates pressure on the article 20 from all angles, thereby achieving a good fixing effect and ensuring that the position of the article 20 remains unchanged during vehicle driving.

[0044] Certainly, in other embodiments, the airbag 100 can also be disposed on one of the groove walls of the placement groove 11. After the cavity 101 of the airbag 100 is filled with gas, the airbag 100 presses the article 20 against the opposite groove wall of the placement groove 11 where the airbag 100 is installed, and can also play a role in fixing the article 20.

[0045] Alternatively, in other embodiments, airbags 100 can also be disposed on the bottom of the placement groove 11 and the inner side of the lid 12. Both of the two airbags 100 have cavities 101 inside, and the two airbags 100 are filled with gas simultaneously. The article 20 is placed in the placement groove 11, and the article 20 is fixed by the two inflated airbags 100.

[0046] Alternatively, in other embodiments, one airbag 100 can be respectively disposed on two opposite groove walls of the placement groove 11. Or, airbags 100 can also be provided on the inner side of the lid 12, the bottom of the placement groove 11, and all groove walls. After the airbags 100 are inflated, the article is completely wrapped. The surface of the airbag 100 facing the article 20 generates pressure on the article 20 from all angles, and the buffering and fixing effects are better, which is beneficial to protecting the storage box 10 and reducing vibration and noise during driving, and the riding experience is good.

[0047] As an optional solution, the air supply mechanism in this embodiment can be the air suspension inflation and deflation system 30 of the vehicle. The cavity 101 is connected to the air suspension inflation and deflation system 30 of the vehicle, and gas can be filled into the cavity 101 through the air suspension inflation and deflation system 30. The abutting portion is the surface of the airbag 100 facing the object 20. After the air suspension inflation and deflation system 30 fills the cavity 101 with gas, the airbag 100 can be elastically deformed and can stretch in the direction of the object 20 until the airbag 100 fills the storage space 13 and the surface of the airbag 100 facing the object 20 is tightly attached to the outer surface of the object 20 and presses the object 20 against the inner wall of the storage box 10.

[0048] Exemplarily, the vehicle article fixing device includes an inflation pipeline 31, and the two ends of the inflation pipeline 31 are respectively connected to the air suspension inflation and deflation system 30 and the cavity 101 of the airbag 100, and the air suspension inflation and deflation system 30 can fill gas into the cavity 101 through the inflation pipeline 31. By using the vehicle's own air suspension inflation and deflation system 30 to inflate the airbag 100, there is no need to set up other inflation components, which helps to save costs and reduce weight, and has a high degree of integration. Of course, in other embodiments, the air supply mechanism can also be other mechanisms on the vehicle with inflation function, which are not listed here one by one.

[0049] Continue to see Figure 1 and Figure 2 The airbag 100 in this embodiment includes a flexible layer, which encloses a cavity 101 , and a surface of the flexible layer close to the storage space 13 can fit with the outer surface of the object 20 .

[0050] As an alternative solution, the flexible layer includes a first flexible layer 110 and a second flexible layer 120. The circumferential edges of the first flexible layer 110 and the second flexible layer 120 are sealingly connected. A cavity 101 is formed between the first flexible layer 110 and the second flexible layer 120. The first flexible layer 110 is located on the side close to the inner wall surface of the storage box 10, and the second flexible layer 120 is located on the side away from the inner wall surface of the storage box 10. The surface of the second flexible layer 120 facing away from the first flexible layer 110 is the abutting portion of the vehicle article fixing device described above. Exemplarily, the circumferential edges between the first flexible layer 110 and the second flexible layer 120 can be connected by hot pressing. After hot pressing the first flexible layer 110 and the second flexible layer 120, an annular hot pressing connection portion is formed between them. The cavity 101 is located inside the hot pressing connection portion, thereby forming a sealed cavity 101 at the center of the airbag 100. Wherein, the first flexible layer 110 and the second flexible layer 120 can be made of the same material and are of an integral structure. Or, the first flexible layer 110 and the second flexible layer 120 can also be made of different materials and are of a split structure. Of course, when the first flexible layer 110 and the second flexible layer 120 are made of the same material, they can also be of a split structure.

[0051] In addition, in some embodiments, the second flexible layer 120 can be made of a flexible material with elastic deformation ability. Thus, before the cavity 101 of the airbag 100 is filled with gas, the airbag 100 can be attached to the inner wall surface of the storage box 10 (i.e., the inner surface of the box cover 12 close to the storage space 13, or the wall or bottom of the placement groove 11). The first flexible layer 110 is in close contact with the inner wall surface of the storage box 10, and the second flexible layer 120 is in close contact with the inner wall surface of the storage box 10 or is arranged with a small gap, without occupying a large space, with high space utilization rate. At the same time, as a whole, the airbag 100 has no protruding structure, and the inner wall surface of the storage box 10 is more beautiful. When in use, the air suspension air charging and discharging system 30 fills the cavity 101 with gas. After the airbag 100 is inflated, the second flexible layer 120 undergoes elastic deformation, expands in the direction of the article 20 and can be attached to the outer surface of the article 20. The second flexible layer 120 fixes the article 20 in the storage box 10 through elastic force, so that the airbag 100 plays a good role in fixing the article 20. When the article 20 needs to be taken out from the storage space 13, the gas in the cavity 101 is released, and the second flexible layer 120 returns to the state before the deformation and continues to be attached to the inner wall surface of the storage box 10.

[0052] Further, an installation part is provided in the circumferential direction of the airbag 100, and the installation part is detachably connected to the inner wall surface of the storage box 10. The airbag 100 can be fixed to the inner wall surface of the storage box 10 through the installation part. Optionally, the installation part is arranged at the circumferential edge of the first flexible layer 110 and the second flexible layer 120, and the installation part is a flange 130 extending outward from the circumferential edge of the first flexible layer 110 and / or the second flexible layer 120. The flange 130 is located outside the hot-pressing connection part, and the flange 130 only needs to be connected to at least one of the first flexible layer 110 and the second flexible layer 120. In some embodiments, the flange 130 can also be a part of the first flexible layer 110 or the second flexible layer 120, that is, the flange 130 and the first flexible layer 110 are of an integral structure. Alternatively, in other embodiments, the flange 130 can also be of an integral structure with the second flexible layer 120.

[0053] Subsequently, taking the detachable connection between the installation part and the lid 12 of the storage box 10 as an example for illustration.

[0054] Continue to refer to Figure 1 and Figure 2 The vehicle article fixing device includes a connecting piece 200. There are fixing holes on the lid 12, and installation holes on the flange 130. The connecting piece 200 passes through the installation holes and is connected to the fixing holes. Exemplarily, the fixing holes can be threaded holes, the installation holes are through holes, the connecting piece 200 is a screw or a bolt, and the screw or the bolt passes through the through hole and is threadedly connected to the threaded hole, thereby fixing the airbag 100 on the lid 12. In order to improve the fixing effect of the airbag 100, multiple fixing holes can be provided on the lid 12, and multiple installation holes are arranged at intervals on the flange 130, and multiple corresponding connecting pieces 200 are also provided, so as to fix the circumferential edge of the airbag 100 on the lid 12 to prevent the airbag 100 from detaching from the lid 12.

[0055] Or, in some other alternative embodiments, a buckle (not shown in the figure) can also be provided on one of the lid 12 and the flange 130, and a clamping groove (not shown in the figure) is provided on the other of the lid 12 and the flange 130. The buckle is snap-connected to the clamping groove, and the connection and fixation between the airbag 100 and the lid 12 can also be realized, and the disassembly and assembly are relatively fast and convenient. Exemplarily, in this embodiment, it is described by taking the flange 130 being provided with a buckle and the lid 12 being provided with a clamping groove as an example.

[0056] Of course, in other embodiments, the installation part can also be arranged on the groove wall or the groove bottom of the placement groove 11, which will not be described in detail here, and the principle is the same as that of arranging the installation part on the lid 12 of the storage box 10.

[0057] Further, in order to avoid injecting excessive gas into the airbag 100, a pressure sensor (not shown in the figure) is provided in the cavity 101 in this embodiment. The pressure sensor is used to detect the air pressure in the cavity 101. When it is necessary to use the airbag 100 to fix the article 20 in the storage box 10, it is necessary to fill the cavity 101 with gas through the air suspension air charging and discharging system 30. When the air pressure in the cavity 101 reaches the maximum pressure threshold of the cavity 101, the air suspension air charging and discharging system 30 stops filling the cavity 101 with gas, thereby avoiding excessive inflation in the cavity 101 and wasting energy.

[0058] The vehicle article fixing device includes an exhaust mechanism (not shown in the figure). The exhaust mechanism is connected to the cavity 101. When the storage box 10 is opened, the exhaust mechanism is triggered, and the gas in the cavity 101 is discharged through the exhaust mechanism. Exemplarily, the exhaust mechanism includes a one-way valve. The one-way valve is provided on the airbag 100 and is in communication with the cavity 101. By providing the one-way valve, when it is necessary to take out the article 20 from the storage space 13, the lid 12 and the one-way valve can be opened, and the airbag 100 will quickly deflate and return to its state before elastic deformation and retract to the inner surface of the lid 12.

[0059] Optionally, the vehicle article fixing device in this embodiment includes a visual detection system. Both the visual detection system and the air supply mechanism are communicatively connected to the control unit. Through the visual detection system, the storage information of the article 20 in the storage space 13 can be detected and transmitted to the control unit. The storage information of the specific article 20 includes the size and shape of the article 20. The control unit determines whether it is necessary to activate the air supply mechanism to inflate the cavity 101 of the airbag 100 accordingly, thereby improving the automation and intelligence level of the vehicle article fixing device. Exemplarily, the visual detection system can be arranged on the inner surface of the lid 12 to facilitate the visual detection system to obtain the storage information of the article 20. The visual detection system can be a band scanner or an infrared detector, etc. Of course, in other embodiments, the visual detection system can also be provided on the wall or bottom of the placement groove 11.

[0060] Furthermore, the vehicle article fixing device further includes a pressure detection system, which is also communicatively connected to the control unit. The pressure detection system is arranged at the bottom of the storage box 10, that is, at the bottom of the placement groove 11. Through the pressure detection system, the pressure information exerted on the storage box 10 by the article 20 in the storage space 13 can be detected and transmitted to the control unit. The control unit can calculate and obtain the weight of the article 20 based on this pressure information. By integrating the storage information of the article 20 transmitted by the above visual detection system, the control unit can comprehensively determine whether to activate the air supply mechanism to inflate the cavity 101 of the airbag 100, and the judgment result is more accurate and the degree of intelligence is higher. It should be noted that when the size of the article 20 is small, similar to a cylindrical or spherical shape, and the weight is lighter, it is more necessary to use the vehicle article fixing device to fix the article 20.

[0061] This embodiment also provides a vehicle. Refer to Figure 3 , the vehicle includes a storage box 10 and the above-mentioned vehicle article fixing device. By adopting the above vehicle article fixing device, the article 20 can be fixed in the storage box 10, ensuring that the position of the article 20 will not move due to inertia in the storage box 10 when the vehicle starts or brakes, avoiding the abnormal noise problem caused by the collision between the article 20 and the inner wall of the storage box 10, and the NVH performance of the whole vehicle is good. At the same time, there is no need to add additional inflation components, and the air suspension inflation and deflation system 30 of the vehicle itself can be used to supply air to the cavity 101 of the airbag 100, making full use of the vehicle configuration and having a high integration degree.

[0062] As an alternative solution, in this embodiment, the vehicle is a new energy vehicle, and the power source of the new energy vehicle is a battery. Since the new energy vehicle does not contain an engine structure, a large amount of space is saved in the front cabin of the vehicle. Therefore, the above storage box 10 can be arranged in the front cabin of the vehicle, the placement groove 11 is arranged at the original engine installation position, the front cabin cover of the vehicle is the above box cover 12, and the airbag 100 is installed on the front cabin cover, thereby providing a larger storage space 13 for customers.

[0063] Of course, the vehicle is also provided with a trunk, and the trunk is also a storage box 10. The trunk lid of the vehicle is the above box cover 12, and the airbag 100 is installed on the trunk lid, thereby providing a larger storage space 13 for customers. By adopting the above vehicle article fixing device, the article 20 placed in the trunk can be prevented from shaking and moving, ensuring good fixation of the article 20 in the trunk when the vehicle starts or brakes.
