Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle component technology, specifically relating to a vehicle door armrest structure, a vehicle door, and a vehicle. Background Technology
[0002] In existing vehicle designs, door handles typically protrude beyond the door body. During a collision, especially a side impact, the side airbag deploys and positions itself between the door and the occupants. At this moment, the force applied to the door encroaches on the door space, compressing the airbag. Due to the structural design of the door handle, the contact area between the handle and the side airbag is relatively small. Under significant external force, the handle can excessively compress the airbag, potentially causing it to rupture and resulting in the occupants colliding with it and sustaining injury. Therefore, how to further improve vehicle safety while ensuring the design requirements of the door handles are met has become a pressing technical problem in this field. Utility Model Content
[0003] This utility model provides a handrail structure for a vehicle door, a vehicle door, and a vehicle, in order to solve the problem that when a vehicle collision occurs, the handrail of the vehicle door excessively intrudes into the interior space, causing injury to the driver and passengers.
[0004] In order to solve or improve the above-mentioned technical problems to a certain extent, this utility model provides a handrail structure for a vehicle door, including: a handrail body and a push-out device;
[0005] The handrail body includes a connector, an upper cover plate, a lower cover plate, and a side cover plate. The connector is used to connect to the vehicle door, and the upper cover plate, the lower cover plate, and the side cover plate are all connected to the connector.
[0006] The armrest body includes a connected state and an extended state. In the connected state, both the upper cover plate and the lower cover plate are connected to the side cover plate. In the extended state, the upper cover plate and / or the lower cover plate are moved away from the side cover plate along the height direction of the vehicle.
[0007] The ejection device is connected to the connector and can drive the upper cover and / or the lower cover to move along the height of the vehicle and toward a direction away from the side cover, so that the armrest body switches from the connected state to the ejection state.
[0008] In some embodiments, the ejection device may drive the upper cover and / or the lower cover to move along the height of the vehicle and toward the side cover, so that the armrest body switches from the ejection state to the connected state.
[0009] In some embodiments, the ejection device includes a drive mechanism and an ejection mechanism;
[0010] The ejection mechanism is connected to the connector, and the upper cover plate and / or the lower cover plate are connected to the ejection mechanism;
[0011] The drive mechanism can drive the ejection mechanism to move the upper cover and / or the lower cover along the height of the vehicle and toward a direction away from the side cover.
[0012] In some embodiments, the driving mechanism includes a drive motor, the ejection mechanism is a telescopic rod, and the drive motor can drive the telescopic rod to be in an extended state and a retracted state.
[0013] In some embodiments, a protective plate is attached to the side of the upper cover and / or the lower cover away from the vehicle door, and the protective plate extends toward the connector along the height direction of the vehicle.
[0014] In some embodiments, when the handrail body is in the ejected state, the height of the protective plate is not less than the distance by which the upper cover plate or the lower cover plate is ejected.
[0015] In some embodiments, when the armrest body is in the extended state, the projections of the upper cover, the lower cover, and the side cover in the direction away from the vehicle door are all on the deployed side airbag.

[0017] According to another aspect of the present invention, a vehicle is provided, including the vehicle door described in any of the above embodiments.
[0018] In some embodiments, the vehicle includes at least one sensor and a side airbag. When the sensor detects a collision, it generates a collision signal. Upon receiving the collision signal, the ejector device drives the armrest body to switch from the connected state to the ejector state, thereby increasing the projected area of the armrest body on the deployed side airbag.
[0019] The upper and / or lower cover plates of the vehicle door armrest structure in this invention are designed to be ejectable. In the event of a vehicle collision and the deployment of the side airbags, the upper and / or lower cover plates are ejected along the vehicle height and in a direction away from the side cover plates of the armrest body, thereby enlarging the projected area of the armrest body on the deployed side airbag. This armrest structure, by increasing the support surface of the armrest on the side airbag during a collision, allows it to absorb more energy from the impact, effectively preventing the armrest from excessively intruding into the vehicle's interior space and causing injury to occupants, thus significantly improving the protection of occupants.

[0037] A: Projected area Detailed Implementation
[0038] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation methods and effects of a vehicle door handrail structure, a vehicle door, and a vehicle based on this utility model.
[0039] Currently, due to the usage and design requirements of vehicle doors, there is a significant gap between the door handle and the map pocket located below the door, resulting in a narrower portion of the handle facing into the vehicle's interior. In the event of a collision, especially a side collision, the vehicle door intrudes into this space under the force of the impact, causing the handle to exert a greater impact force on the deployed side airbag. The narrow handle structure, under such a strong impact, increases the displacement of the handle towards the interior, potentially causing excessive compression of the side airbag or even airbag rupture, leading to a collision between the occupants and the handle, resulting in injury.
[0040] Based on this situation, an embodiment of the present invention provides a handrail structure for a vehicle door 30, such as... Figures 1-4 As shown, the armrest includes a body 10 and a push-out device 20. The armrest body 10 includes a connector 100, an upper cover plate 102, a lower cover plate 104, and a side cover plate 106. The upper cover plate 102, lower cover plate 104, and side cover plate 106 are all directly or indirectly connected to the connector 100. The connector 100 is connected to the vehicle door 30 to achieve the connection between the armrest body 10 and the vehicle door 30.
[0041] The armrest body 10 includes a connected state (such as...) Figure 1 (as shown) and ejection state (as shown) Figure 2 As shown, when the armrest body 10 is in the connected state, its upper cover 102 and lower cover 104 are both connected to the side cover 106. When a vehicle collision occurs, the armrest body 10 switches from the connected state to the ejected state. In the ejected state, the upper cover 102 and / or the lower cover 104 move away from the side cover 106 along the height direction of the vehicle, effectively increasing the projected area A of the armrest body 10 on the deployed side airbag 40, increasing the contact area between the armrest body 10 and the side airbag 40, thereby enabling the side airbag 40 to absorb more of the impact force from the collision.
[0042] In one embodiment, such as Figure 4 and Figure 5 As shown, when the armrest body 10 is in the extended state, the projections of the upper cover 102, lower cover 104 and side cover 106 in the direction away from the vehicle door 30 are all on the side airbag 40 in the deployed state, so as to further ensure the contact area between the armrest body 10 and the side airbag 40.
[0043] In some embodiments, when the handrail body 10 is in the extended state, the upper cover plate 102 may be extended in a direction away from the side cover plate 106, while the lower cover plate 104 remains connected to the side cover plate 106; the lower cover plate 104 may be extended in a direction away from the side cover plate 106, while the upper cover plate 102 remains connected to the side cover plate 106; or both the upper cover plate 102 and the lower cover plate 104 may be extended in a direction away from the side cover plate 106.
[0044] Preferably, such as Figures 3-5 As shown, when the armrest body 10 is in the extended state, the upper cover 102 and the lower cover 104 are simultaneously extended in a direction away from the side cover 106. Specifically, the upper cover 102 is extended in a direction toward the top of the vehicle, while the lower cover 104 is extended in a direction toward the chassis of the vehicle.
[0045] like Figure 2 As shown, the ejection device 20 is connected to the connector 100 of the armrest body 10. When a vehicle collision occurs, the ejection device 20 drives the upper cover 102 and / or the lower cover 104 to move along the height of the vehicle and toward the direction away from the side cover 106, so that the armrest body 10 switches from the connected state to the ejection state.
[0046] Optionally, such as Figure 4 As shown, the ejection device 20 includes a drive mechanism (not shown) and an ejection mechanism 200, wherein the ejection mechanism 200 is connected to the connector 100, and the upper cover plate 102 and / or lower cover plate 104 of the armrest body 10 are connected to the ejection device 20. In the event of a vehicle collision, the drive mechanism drives the ejection mechanism 200 to move, causing the ejection mechanism 200 to eject the upper cover plate 102 and / or lower cover plate 104 connected to it, enabling it to move along the height of the vehicle and in a direction away from the side cover plate 106, thus switching the armrest body 10 from a connected state to an ejected state.
[0047] In one embodiment, the driving mechanism is a hydraulic cylinder, and the ejection mechanism 200 is a hydraulic rod. When a vehicle collision occurs, the pressure inside the hydraulic cylinder increases, driving the hydraulic cylinder to eject the upper cover plate 102 and / or lower cover plate 104 of the handrail body 10.
[0048] In one embodiment, the driving mechanism is a drive motor, and the ejection mechanism 200 is a telescopic rod. When a vehicle collision occurs, the drive motor drives the telescopic rod to extend, so as to eject the upper cover plate 102 and / or lower cover plate 104 of the handrail body 10.
[0049] In one embodiment, the driving mechanism is a gas generating device, and the ejection mechanism 200 is an airbag. When a vehicle collision occurs, the gas generating device generates gas to drive the airbag to inflate, thereby ejecting the upper cover plate 102 and / or lower cover plate 104 of the armrest body 10.
[0050] In one embodiment, the ejection device 20 can also drive the upper cover plate 102 and / or lower cover plate 104 of the armrest body 10 to move along the height of the vehicle and toward the direction of the side cover plate 106, so that the armrest body 10 switches from the ejection state to the connection state, thereby enabling the armrest body 10 to automatically return to the normal state (i.e. the connection state), so as to avoid the need for repair or replacement of the armrest structure in the event of a minor collision or a non-side collision.
[0051] In this embodiment, the driving mechanism of the ejector device 20 is a drive motor, and the ejector mechanism 200 is a telescopic rod. After a vehicle collision, the drive motor drives the telescopic rod to a retracted state, so that the upper cover plate 102 and / or the lower cover plate 104 are connected to the side cover plate 106, thereby switching the handrail body 10 to a connected state.
[0052] In one embodiment, in order to improve the support strength of the armrest body 10 in the extended state, such as Figures 3-5 As shown, a protective plate 108 is connected to the side of the upper cover plate 102 and / or the lower cover plate 104 away from the vehicle door 30, that is, a protective plate 108 is connected to the side of the upper cover plate 102 and / or the lower cover plate 104 facing the side cover plate 106, and the protective plate 108 extends toward the connector 100 of the armrest body 10 along the height direction of the vehicle.
[0053] When the upper cover 102 and / or the lower cover 104 are pushed out by the push-out device 20, the protective plate 108 will move synchronously. Thus, when the armrest body 10 is in the pushed-out state, the upper cover 102, the lower cover 104, the protective plate 108 and the side cover 106 together form a surface facing the interior space of the vehicle.
[0054] Optionally, the height of the protective plate 108 is not less than the distance by which the upper cover plate 102 and / or the lower cover plate 104 are pushed out when the armrest body 10 is in the pushed-out state. The height of the protective plate 108 is the height of the protective plate 108 along the vehicle height direction; that is, when the armrest body 10 is in the pushed-out state, the end of the protective plate 108 not connected to the upper cover plate 102 and / or the lower cover plate 104 is flush with one end of the side cover plate 106, or the end of the protective plate 108 not connected to the upper cover plate 102 and / or the lower cover plate 104 is within the coverage area of the side cover plate 106 projected onto the vehicle door 30.
[0055] In this embodiment, by limiting the height of the protective plate 108, it is possible to avoid the formation of a gap between the protective plate 108 and the side cover plate 106 in the event of a collision, and the side airbag 40 being cut by the protective plate 108 or the side cover plate 106 when it extends into the gap.
[0056] Another embodiment of this utility model provides a vehicle door, including a door body and a handrail structure as described in any of the above embodiments. The handrail body 10 is connected to the door body via a connector 100.
[0057] Another embodiment of the present invention provides a vehicle that includes at least one sensor (not shown in the figure), a side airbag 40, and a vehicle door 30 as described in the above embodiment.
[0058] Sensors are used to detect whether a collision has occurred. When a collision is detected, a collision signal is generated. After receiving the collision signal, the airbag control unit controls the side airbag 40 to deploy. Simultaneously, after receiving the collision signal, the push-out device 20 drives the armrest body 10 to switch from the connected state to the push-out state, thereby increasing the projected area A of the armrest body 10 on the deployed side airbag 40. This allows the side airbag 40 to absorb more of the impact force from the collision.
[0059] The upper and / or lower cover plates of the vehicle door armrest structure in this invention are designed to be ejectable. In the event of a vehicle collision and the deployment of the side airbags, the upper and / or lower cover plates are ejected along the vehicle height and in a direction away from the side cover plates of the armrest body, thereby enlarging the projected area of the armrest body on the deployed side airbag. This armrest structure, by increasing the support surface of the armrest on the side airbag during a collision, allows it to absorb more energy from the impact, effectively preventing the armrest from excessively intruding into the vehicle's interior space and causing injury to occupants, thus significantly improving the protection of occupants.
[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
