Vehicle door and vehicle

Abstract

The vehicle door and vehicle of this application include a door body, a lock body and handle mounted on the door body, a pull cable and an unlocking mechanism. The handle and lock body are connected by a connecting rope. The pull cable is fitted onto the connecting rope and slidably connected to it. A latch is mounted on the door body and abuts against the pull cable to limit its position. The unlocking mechanism is mounted on the pull cable and is connected to the latch. The unlocking mechanism, driven by the pull cable, can release the latch from its position on the door body, allowing the pull cable to disengage from the latch. Thus, when the vehicle door is subjected to a side impact and collapses inward, the pull cable can activate the unlocking mechanism, causing the latch to release the pull cable. This increases the movable length of the connecting rope, compensating for the displacement of the pull cable as the door collapses inward. This prevents the connecting rope from detaching from the handle or the lock body from unlocking, thereby improving the safety of the vehicle door.

Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle door unlocking, and in particular relates to a vehicle door and a vehicle. Background Technology

[0002] In vehicle door structures, the outward-opening handle and the lock body are typically connected by a steel cable, enabling the outward-opening handle to control the lock's unlocking. To improve the stability of the steel cable and reduce noise, a pull wire is usually fitted around the outside of the steel cable and secured to the door with clips. However, when the door suffers a side impact and collapses inward, the pull wire, restrained by the clips, has insufficient deformation margin. This allows the pull wire to exert an additional tension on the internal steel cable during the collapse. This tension may be transmitted to the lock body or the connection point of the outward-opening handle, causing the steel cable to detach or the lock body to unlock abnormally. Consequently, the outward-opening handle may be unable to control the lock's unlocking after the impact, or the door may accidentally open during the collision, posing a serious safety hazard. Utility Model Content

[0003] In view of this, it is necessary to provide a vehicle door and a vehicle for solving the above-mentioned technical problems.

[0004] A vehicle door, the vehicle door comprising:

[0005] Door body;

[0006] A lock body is installed on the door.

[0007] A handle is installed on the door body, and the handle is connected to the lock body by a connecting rope.

[0008] A pull line is fitted onto the connecting rope and slidably connected to the connecting rope;

[0009] A buckle is installed on the door body and abuts against and limits the pull line, used to limit the pull line to the door body;

[0010] An unlocking device is installed on the pull line and is connected to the buckle for transmission. The unlocking device can drive the buckle to release the pull line from the door body under the action of the pull line, so that the pull line can disengage from the buckle.

[0011] Understandably, by adding an unlocking mechanism to the cable, when the vehicle door is subjected to a side impact and collapses inward, the cable can activate the unlocking mechanism, causing the latch to release the cable. This increases the movable length of the connecting rope to compensate for the displacement of the cable as the door collapses inward, thereby preventing the connecting rope from detaching from the handle or the lock from unlocking, thus improving the safety of the vehicle door.

[0012] In one embodiment, the buckle includes a base and a latching arm, the latching arm being snapped into the base; and a limiting cavity is formed between the latching arm and the base.

[0013] The pull wire passes through the limiting cavity, and the opening component abuts against the hook portion on the card arm.

[0014] In one embodiment, the card release member has a wedge-shaped surface, and the card release member can push the card hook portion through the wedge-shaped surface to release the engagement between the card arm and the base.

[0015] Understandably, the opening mechanism releases the latch between the latch arm and the base by pushing the wedge-shaped surface against the latch hook, thus simplifying the engagement structure between the opening mechanism and the latch.

[0016] In one embodiment, the wedge-shaped surface includes a first wedge-shaped surface and a second wedge-shaped surface;

[0017] Along the direction in which the pull line passes through the limiting cavity, the first wedge-shaped surface and the second wedge-shaped surface are disposed on both sides of the hook portion; and the opening member can push the hook portion through the first wedge-shaped surface or the second wedge-shaped surface.

[0018] Understandably, the release mechanism uses the first and second wedge-shaped surfaces located on both sides of the hook portion to release the engagement between the latch arm and the base, so that the release mechanism can control the release cable of the latch when it moves in two opposite directions. This ensures that when the vehicle door is subjected to a side impact and collapses inward, the release mechanism can control the release cable of the latch.

[0019] In one embodiment, the card opening component further has a guide surface, which is disposed between the first wedge surface and the second wedge surface, and is transitionally connected to the first wedge surface and the second wedge surface respectively, and the guide surface is disposed against the card hook portion.

[0020] Understandably, the card release mechanism is guided to the first or second wedge surface by a guide surface. This improves the smoothness of the card release mechanism when it performs a relative snapping action, ensuring that the card release mechanism can drive the snapping release cable when it is in action.

[0021] In one embodiment, the card release mechanism includes an unlocking lever that extends along the direction in which the pull line passes through the limiting cavity;

[0022] Furthermore, both the first wedge-shaped surface and the second wedge-shaped surface are disposed on the unlocking rod.

[0023] In one embodiment, the card opening component further includes a connector that is tightly fitted to the pull wire.

[0024] Understandably, the card opener is fitted onto the pull line in a tight fit manner, which facilitates its assembly on the pull line.

[0025] In one embodiment, the connector includes a first half and a second half, which together form a sleeve hole through which the pull wire can pass;

[0026] One end of the first half is rotatably connected to one end of the second half, and the other end of the first half is snapped into place with the other end of the second half.

[0027] It is understandable that a snap-fit ​​method is used to assemble the connecting body on the pull wire, which facilitates the assembly of the connecting body on the pull wire.

[0028] In one embodiment, the card opening component is configured as an injection molded part.

[0029] It is understandable that configuring the card opening component as an injection molded part allows it to be manufactured using injection molding, which facilitates its production and reduces costs.

[0030] This application also provides a vehicle including the vehicle door described above.

[0031] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0032] The vehicle door and vehicle for which this application seeks protection, by adding an unlocking mechanism to the pull cable, enable the pull cable to activate the unlocking mechanism when the vehicle door is subjected to a side impact and collapses inward, thereby causing the latch to release the pull cable. This increases the movable length of the connecting rope to compensate for the displacement of the pull cable as the door collapses inward, thus preventing the connecting rope from pulling off the handle or the lock from unlocking, and improving the safety of the vehicle door.

Detailed Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figures 1 to 5As shown, the vehicle door 100 provided in this application includes a door body 10, a lock body 20, a handle 30, a pull cable 40, a buckle 50, and an unlocking device 60. The lock body 20 and handle 30 are both mounted on the door body 10. The handle 30 and lock body 20 are connected via a connecting rope (not shown). The pull cable 40 is fitted onto the connecting rope and slidably connected to it. The buckle 50 is mounted on the door body 10 and abuts against the pull cable 40, limiting the pull cable 40 to the door body 10. The unlocking device 60 is mounted on the pull cable 40 and is connected to the buckle 50. The unlocking device 60, driven by the pull cable 40, can cause the buckle 50 to release the pull cable 40 from its position on the door body 10, allowing the pull cable 40 to disengage from the buckle 50. Here, the connecting rope is configured as a steel wire rope or other high-strength nylon rope, etc. It should be noted that the pull cable 40 in this application is configured as a rigid tubular sleeve.

[0044] As can be seen from the above, the vehicle door 100 of this application can use the buckle 50 to limit the assembly of the pull cable 40 and the connecting rope on the door body 10, preventing the connecting rope from colliding with the door body 10 and generating noise; when the vehicle door 100 is subjected to a side collision and collapses inward, the pull cable 40 can drive the opening piece 60 to move, causing the buckle 50 to release the pull cable 40. This increases the movable length of the connecting rope to compensate for the displacement of the pull cable 40 as the door body 10 collapses inward, thereby avoiding the situation where the connecting rope is pulled out from the handle 30 or the lock body 20 is unlocked, thus improving the safety of the vehicle door 100.

[0045] It should be noted that when the connecting rope of this application is fixed to the door body 10 by the buckle 50 through the pull line 40, the connecting rope is in a taut state. Once the pull line 40 drives the connecting rope to disengage from the buckle 50, the connecting rope will switch from a taut state to a loose state, thus increasing the movable length of the connecting rope.

[0046] like Figure 2 , Figure 4 As shown, in one embodiment, the buckle 50 includes a base 51 and a latching arm 52, with the latching arm 52 engaging with the base 51. Furthermore, a limiting cavity 501 is formed between the latching arm 52 and the base 51, through which a pull wire 40 can pass, thereby achieving assembly limiting between the buckle 50 and the pull wire 40. Here, an undercut 511 is formed on the base 51, and the base 51 can drive the undercut 511 to insert into the corresponding mounting point on the door 10. The positional interference between the undercut 511 and the door 10 is used to achieve the assembly connection of the buckle 50 on the door 10.

[0047] like Figure 4As shown, in this embodiment, the opening member 60 abuts against the hook portion 521 on the locking arm 52. That is to say, when the opening member 60 in this embodiment is activated, it can release the locking between the locking arm 52 and the base 51 by pushing the hook portion 521, and release the locking arm 52 from limiting the pull line 40 on the base 51.

[0048] like Figures 2 to 4 As shown, in one embodiment, the unlocking member 60 has a wedge-shaped surface 61, and the unlocking member 60 can push the hook portion 521 through the wedge-shaped surface 61 to release the engagement between the locking arm 52 and the base 51. That is to say, when the unlocking member 60 of this embodiment is activated, it can release the engagement between the locking arm 52 and the base 51 by pushing the hook portion 521 through the wedge-shaped surface 61, which simplifies the cooperation structure between the unlocking member 60 and the buckle 50.

[0049] like Figures 2 to 4 As shown, in this embodiment, the wedge-shaped surface 61 includes a first wedge-shaped surface 611 and a second wedge-shaped surface 612; along the direction in which the pull line 40 passes through the limiting cavity 501, the first wedge-shaped surface 611 and the second wedge-shaped surface 612 are disposed on both sides of the hook portion 521; and the unlocking member 60 can push the hook portion 521 through the first wedge-shaped surface 611 or the second wedge-shaped surface 612. That is to say, in this embodiment, the unlocking member 60 can control the latch 50 to release the pull line 40 when it moves in two opposite directions, thus ensuring that when the vehicle door 100 suffers a side collision and collapses inward, the unlocking member 60 can control the latch 50 to release the pull line 40.

[0050] like Figures 2 to 4 As shown, in this embodiment, the unlocking component 60 also has a guide surface 62, which is disposed between the first wedge-shaped surface 611 and the second wedge-shaped surface 612, and is transitionally connected to both the first wedge-shaped surface 611 and the second wedge-shaped surface 612, respectively. The guide surface 62 is also disposed against the hook portion 521. In other words, the unlocking component 60 can be guided to either the first wedge-shaped surface 611 or the second wedge-shaped surface 612 by the guide surface 62. This improves the smoothness of the unlocking component 60's movement relative to the latch 50, ensuring that the unlocking component 60 can drive the latch 50 to release the pull wire 40 when it moves. Here, the guide surface 62 is connected to the first wedge-shaped surface 611 and the second wedge-shaped surface 612 by arc surfaces.

[0051] like Figures 2 to 4As shown, in this embodiment, the unlocking component 60 includes an unlocking rod 610, which extends along the direction in which the pull wire 40 passes through the limiting cavity 501; and both the first wedge-shaped surface 611 and the second wedge-shaped surface 612 are disposed on the unlocking rod 610. Here, the guide surface 62 is also disposed on the unlocking rod 610, which simplifies the structural configuration of the unlocking component 60. It is understood that in other embodiments, the unlocking component 60 may also have the first wedge-shaped surface 611, the second wedge-shaped surface 612, and the guide surface 62 disposed on three separate components, which will not be elaborated here.

[0052] like Figures 2 to 4 As shown, in one embodiment, the unlocking component 60 further includes a connecting body 620, which is tightly connected to the pull wire 40. This allows for assembly limiting of the unlocking component 60 on the pull wire 40, facilitating its assembly. Here, two connecting bodies 620 are configured, located at both ends of the unlocking lever 610, providing two fixed points between the unlocking component 60 and the pull wire 40. This improves the stability of the unlocking component 60's assembly on the pull wire 40.

[0053] like Figure 3 As shown, in this embodiment, the connector 620 includes a first half and a second half, which together form a sleeve hole 621 through which the pull wire 40 can pass. One end of the first half is rotatably connected to one end of the second half, and the other end of the first half is snapped into place with the other end of the second half. In other words, the connector 620 in this embodiment can be assembled onto the pull wire 40 using a snap-fit ​​method, thus facilitating its assembly.

[0054] In one embodiment, the card opening component 60 is configured as an injection molded part, so that the card opening component 60 can be manufactured by injection molding, which facilitates the manufacturing of the card opening component 60 and reduces costs.

[0055] As can be seen from the above, when the vehicle door 100 of this application is in normal use, when the handle 30 is pulled by the user, the handle 30 drives the connecting rope to slide within the pull cable 40, thereby driving the lock body 20. This allows the lock body 20 to release the lock on the door 10, thus unlocking the vehicle door 100 on the vehicle. It should be noted that the assembly of the handle 30 and lock body 20 on the door 10, and how the lock body 20 controls the unlocking of the door 10 under the pull of the connecting rope, can all adopt the conventional method of the outward-opening pull cable structure on existing vehicle doors, and will not be elaborated here.

[0056] In addition, this application also provides a vehicle including the vehicle door 100 described above.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
