Description

Technical Field

[0001] The invention relates to the technical field of automobiles, in particular to a height-variable auxiliary instrument panel structure and a vehicle. Background Art

[0002] Automobile collision safety performance has always been a performance that consumers pay close attention to. In order to meet customer needs and increase sales, most new models launched by automobile companies meet the C-NCAP 5-star requirements. Currently, the requirements for remote occupant protection have been added to the collision conditions, accounting for 4 points. In many cases, this score directly affects the achievement of the 5-star goal, so remote occupant protection has risen to a very important position from the regulatory level.

[0003] Under the new regulations and new working conditions, automakers have actively taken a variety of measures to improve the performance of remote protection. First, add a center airbag. In a side column collision, the airbag is detonated by the collision signal to effectively prevent the heads of the two front passengers from directly contacting each other and reduce the displacement of the head of the remote passenger. However, if only this airbag can completely avoid deductions, the airbag needs to be larger and may need to be multi-stage and multi-cavity, which has a high development cost. Another measure is to ensure sufficient distance between passengers. However, this not only affects the main dimensions of the vehicle model, but also affects the human-machine layout, so its implementation is greatly restricted. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a variable height auxiliary instrument panel structure and vehicle, which is equipped with an auxiliary instrument panel that can be raised in height as a whole during a collision. It can provide strong support for the center airbag in a side collision without increasing the volume of the airbag, and it itself also has the function of preventing direct contact between occupants.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, a variable height auxiliary instrument panel structure includes:

[0007] A plurality of layers of auxiliary instrument panel component assemblies, each layer of auxiliary instrument panel component assemblies and the first layer of auxiliary instrument panel component assembly and the vehicle body are connected by a connecting piece; the connecting piece includes a pair of sleeve pieces arranged opposite to each other, the two sleeve pieces are sleeved and matched, and have a filling space inside;

[0008] The filling component is connected to the filling space through a pipeline. The filling component fills gas or liquid into the filling space to extend the connecting piece and lift the auxiliary instrument panel as a whole.

[0009] As a further implementation, each group of the connecting members includes an upper sleeve member and a lower sleeve member, the opposite ends of the upper sleeve member and the lower sleeve member are open, and the upper sleeve member is slidably sleeved on the lower sleeve member.

[0010] As a further implementation, the opposite ends of the upper sleeve member and the lower sleeve member are connected to the vehicle body or the auxiliary instrument panel component assembly via a connecting plate.

[0011] As a further implementation, the connecting plate is rectangular and is provided with mounting holes.

[0012] As a further implementation, a sealing ring is provided between the upper sleeve member and the lower sleeve member.

[0013] As a further implementation, the upper sleeve member and the lower sleeve member are internally connected via a spring.

[0014] As a further implementation, the spring connection is connected between connecting plates of the upper sleeve member and the lower sleeve member.

[0015] As a further implementation, the filling assembly includes a high-pressure gas cylinder, which is connected to a sleeve member via a pipeline with a solenoid valve, and the solenoid valve is connected to an execution control unit.

[0016] As a further implementation, the filling assembly includes a water tank, a water pump is provided in the water tank, the water pump is connected to the sleeve member through a pipeline, and the water pump is connected to the execution control unit.

[0017] In a second aspect, a vehicle is provided with a variable height sub-instrument panel structure as described above. In case of a collision, the vehicle control unit sends a collision signal to the execution control unit of the charging component, and the execution control unit issues a command to start the charging component, thereby raising the sub-instrument panel as a whole.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The invention is provided with a sub-dashboard that can be raised in height as a whole in the event of a collision, which can provide strong support for the center airbag in a side collision without increasing the volume of the airbag, and it can also prevent direct contact between passengers. This structure also reduces the requirement for the lateral distance between passengers, greatly improving safety performance.

[0020] 2. The connecting piece of the present invention is composed of an upper sleeve piece and a lower sleeve piece, which can not only serve as a connecting piece for assembling different sub-instrument panels through a connecting plate, but is also connected to a filling assembly. In the event of a collision, it can serve as a lifting piece for the sub-instrument panel, so that the height of the sub-instrument panel can be quickly raised in the event of a collision, thereby ensuring safety.

DETAILED DESCRIPTION

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1

[0031] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 5 As shown, a variable height auxiliary instrument panel structure includes several layers of auxiliary instrument panel component assemblies, and each layer of auxiliary instrument panel component assemblies and the first layer of auxiliary instrument panel component assemblies and the vehicle body 4 are connected by connecting members 5.

[0032] like Figure 1-Figure 3 As shown, the auxiliary instrument panel of this embodiment includes three layers, namely, the auxiliary instrument panel first component assembly 1 of the first layer, the auxiliary instrument panel second component assembly 2 of the second layer, and the auxiliary instrument panel third component assembly 3 of the third layer.

[0033] The first-layer auxiliary instrument panel first component assembly 1 is connected to the vehicle body 4 through a plurality of connectors 5, the second-layer auxiliary instrument panel second component assembly 2 is located above the auxiliary instrument panel first component assembly 1 and is connected to each other through connectors 5, and the auxiliary instrument panel second component assembly 2 and the auxiliary instrument panel third component assembly 3 above it are connected to each other through connectors 5. In other examples, the auxiliary instrument panel component assembly has only two layers.

[0034] like Figure 4 As shown, the connecting member 5 includes a pair of sleeve members arranged opposite to each other, the two sleeve members are sleeved and matched, and there is a filling space inside, each set of connecting members 5 includes an upper sleeve member 51 and a lower sleeve member 52, the opposite ends of the upper sleeve member 51 and the lower sleeve member 52 are open, and the other end is provided with a connecting plate for sealing. The upper sleeve member 51 is slidably sleeved on the lower sleeve member 52.

[0035] Specifically, the opening of the upper sleeve member 51 is downward, the opening of the lower sleeve member 52 is upward, the top end of the upper sleeve member 51 is an upper connecting plate 53, and the bottom end of the lower sleeve member is a lower connecting plate 54. The upper connecting plate 53 is connected to the upper assembly, and the lower connecting plate 54 is connected to the lower assembly or the vehicle body 4.

[0036] The upper connecting plate 53 and the lower connecting plate 54 are rectangular, and are respectively provided with an upper mounting hole 55 and a lower mounting hole 56 , and are connected to the assembly through the mounting holes and bolt assemblies.

[0037] In other examples, the connection form between the connecting plate and the assembly may also be welding points, riveting, welding, etc.

[0038] The upper sleeve member 51 and the lower sleeve member 52 are sleeved with each other, and the enclosed internal space is the filling space, and a sealing ring 57 is provided between the upper sleeve member 51 and the lower sleeve member 52 to achieve sealing fit.

[0039] The upper sleeve member 51 and the lower sleeve member 52 are connected internally by a spring 58, and the spring 58 is connected between the connecting plates of the upper sleeve member 51 and the lower sleeve member 52. Specifically, one end of the spring 58 is connected to the upper connecting plate 53, and the other end is connected to the lower connecting plate 54. In a natural state, the spring 58 has a tendency to pull the upper sleeve member 51 and the lower sleeve member 52 closer to each other.

[0040] like Figure 4 and Figure 5 As shown, the filling assembly 6 is connected to the filling space through a pipeline. The filling assembly 6 fills gas or liquid into the filling space to extend the connector and lift the auxiliary instrument panel as a whole.

[0041] In an optional example, the filling assembly 6 can be a high-pressure gas cylinder, which is connected to the sleeve member through a pipeline with a solenoid valve, the solenoid valve is connected to the execution control unit, and the end of the pipeline is connected to the lower position of the lower sleeve member, or it is connected to the internal filling space through the lower connecting plate, but it cannot affect the installation between the lower connecting plate and other structures.

[0042] In an optional example, the filling component includes a water tank, a water pump is provided in the water tank, the water pump is connected to the sleeve member through a pipeline, and the water pump is connected to the execution control unit.

[0043] The execution control unit on the vehicle body can issue a filling component start instruction according to the collision signal sent by the vehicle control unit of the vehicle, so as to realize the filling of the filling space inside the sleeve.

[0044] Specifically, after the vehicle is hit from the side, the vehicle control unit will instantly send a collision signal to the execution control unit, and the hydraulic execution control unit will execute the corresponding command to open the solenoid valve of the water pump or the high-pressure gas cylinder to fill the gas or water into the filling space between the upper sleeve member 51 and the lower sleeve member 52. Under the action of pressure, the upper sleeve member 51 and the lower sleeve member 52 move away from each other, so that the connecting member 5 is stretched as a whole. In this way, the entire auxiliary instrument panel structure is lifted as a whole.

[0045] When the filling component 6 selects a high-pressure gas cylinder, after the solenoid valve is opened, gas enters the connector, the connector is extended, the multi-layer auxiliary instrument panel component assembly is lifted, and the spring is stretched to the maximum limit. Similarly, the water pump pumps water into the connector, which can also extend the connector.

[0046] It is understandable that when the connector 5 is damaged after a collision, it is necessary to replace the parts when repairing the vehicle. The water pressure in the water tank or the air pressure in the gas cylinder can be determined according to actual needs. If the spring 58 is not broken, or the connection between the spring and the connecting plate is not disconnected, it can be determined that the connector can continue to be used. A sealing cover can be set on the connecting plate, and the sealing cover can be opened to release pressure, and the connector can return to its original height.

[0047] It can be understood that the filling degree of the filling assembly 6, that is, the rising height of the auxiliary instrument panel, is determined by the strength of the acceleration signal in the side collision sent by the vehicle control unit.

[0048] This embodiment is provided with a sub-dashboard that can be lifted up as a whole in the event of a collision, which can provide strong support for the center airbag in a side collision without increasing the volume of the airbag, and it can also prevent direct contact between passengers. This structure also reduces the requirement for the lateral distance between passengers, greatly improving safety performance while not affecting the man-machine interface.

It can provide strong support for the center airbag in a side collision without increasing the volume of the airbag.
