Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an armrest locking device, a door armrest, and a vehicle. Background Technology

[0002] With the development of vehicle products, some vehicles have storage boxes in the door interior trim. The door armrest can cover the opening of the storage box. The door armrest is an important vehicle interior trim. It can not only support the elbows of the driver and passengers and relieve their fatigue, but also prevent the items stored in the storage box from flying out to a certain extent.

[0003] Traditional handrail locking devices have many parts, which increases the complexity of production, the workload and time on the production line, which undoubtedly increases production costs. In addition, the probability of failure after the parts are assembled is relatively high, affecting the stability of use.

[0004] Therefore, it is urgent to solve the problems of complex production and unsatisfactory working stability caused by the large number of parts in the handrail locking device. Utility Model Content

[0005] In view of this, embodiments of this application provide a handrail locking device, a door handrail, and a vehicle to solve the technical problems of complex production and unsatisfactory working stability caused by the large number of parts in the handrail locking device.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] In a first aspect, embodiments of this application provide a handrail locking device, comprising:

[0008] An armrest assembly is rotatably connected to a storage box located on a vehicle door to open and close the retrieval opening of the storage box, and the armrest assembly has a receiving cavity.

[0009] A locking assembly is movably disposed within the receiving cavity, and the locking assembly is configured to lock the armrest assembly to the retrieval opening so that the armrest assembly blocks the retrieval opening;

[0010] An unlocking component is movably disposed on the armrest assembly and elastically abuts against the locking assembly. The unlocking component is used to drive the locking assembly to move in a first direction to unlock the armrest assembly from the access opening.

[0011] This application provides a handrail locking device in which an unlocking component elastically abuts against a locking component. The unlocking component can directly drive the locking component to unlock, eliminating the need for an additional transmission component between the unlocking component and the locking component. This simplifies the structure of the handrail locking device, reduces the number of parts, lowers production complexity, helps save production costs, improves operational stability, and also helps reduce problems such as aging, wear, and noise of parts, thereby improving vehicle quality and enhancing the user experience.

[0012] In one possible implementation of this application, the storage box has a lock hole, and the locking assembly includes a locking bar and a latch connected to at least one end of the locking bar, the latch extending into the lock hole.

[0013] In one possible implementation of this application, the armrest assembly includes a lower armrest shell and an upper armrest shell connected to each other, the receiving cavity is formed between the lower armrest shell and the upper armrest shell, the locking assembly is slidably disposed in the receiving cavity, the locking tongue extends out of the receiving cavity and extends into the lock hole along the first direction.

[0014] In one possible implementation of this application, the handrail locking device further includes a reset member disposed between the unlocking member and the locking rod, with both ends of the reset member elastically abutting against the unlocking member and the locking rod, respectively.

[0015] In one possible implementation of this application, the unlocking member includes an operating part and a connecting post connected to each other, the operating part extending out of the armrest assembly, the connecting post extending into the receiving cavity, and the reset member sleeved on the connecting post.

[0016] In one possible implementation of this application, the locking assembly further includes an elastic element disposed on the side of the locking rod opposite to the unlocking element, and the elastic element elastically abuts against the locking rod and the inner wall of the receiving cavity.

[0017] In one possible implementation of this application, the locking rod has a positioning post on the side opposite to the unlocking member, and the elastic member is sleeved on the positioning post.

[0018] In one possible implementation of this application, both ends of the locking rod are provided with locking tongues, and the extension direction of the locking tongues forms an angle with the extension direction of the locking rod.

[0019] Secondly, embodiments of this application provide a car door armrest, including:

[0020] Storage box; and the aforementioned handrail locking device.

[0021] Thirdly, embodiments of this application provide a vehicle, including:

[0022] The vehicle body; and the aforementioned door handles.

[0023] The present application provides a handrail locking device, a door handrail, and a vehicle. The locking component and unlocking component have a simple structure. By operating the unlocking component, such as by pressing the unlocking component, the connecting column of the unlocking component pushes the locking rod to move in a first direction, thereby achieving unlocking. The unlocking action is simple and efficient, without the need for complex transmission components, which helps to reduce the failure rate and improve the stability of use.

[0024] This application provides a handrail locking device, a door handrail, and a vehicle.

[0060] Armrest locking devices are usually installed on the door trim panels. Storage boxes are used to store various small items, such as mobile phones, wallets, water bottles, umbrellas, etc., which can improve the utilization efficiency of the interior space and make it convenient for drivers and passengers to store and access daily items. The armrest components on the storage boxes can support the arms, allowing the arms to rest effectively and preventing soreness, numbness, and stiffness.

[0061] During vehicle operation, to prevent items stored in the glove compartment from flying out and causing injury during emergency braking or accidents, the armrest assembly needs to cover the retrieval opening when items are not being retrieved, keeping it closed. It's also crucial to ensure the stability of the closure to prevent accidental opening. Therefore, a locking mechanism is used to lock the armrest assembly to the glove compartment's retrieval opening. However, traditional structures for locking the armrest assembly to the retrieval opening and unlocking the locking mechanism typically involve gear transmission components. This is complex, requires numerous parts, is costly, and has a high failure rate due to issues such as gear wear and noise, ultimately affecting vehicle quality.

[0062] In view of this, this application provides a handrail locking device, a door handrail, and a vehicle. The unlocking component elastically abuts against the locking component, and the unlocking component directly drives the locking component to unlock. There is no need to add a transmission component between the unlocking component and the locking component, which helps to simplify the structure of the handrail locking device, reduce the number of parts, reduce the complexity of production, help save production costs, improve the stability of operation, and can also effectively reduce the aging, wear and noise of parts, improve the quality of the vehicle, and enhance the user experience.

[0063] The following description, with reference to the accompanying drawings, illustrates a handrail locking device, a door handrail, and a vehicle provided in this application.

[0064] Firstly, reference Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a handrail locking device, including: a handrail assembly 20, a locking assembly 30, and an unlocking member 40. The handrail assembly 20 is rotatably connected to a storage box 10 disposed on a vehicle door to open and close the retrieval opening 12 of the storage box 10. The handrail assembly 20 has a receiving cavity 23. The locking assembly 30 is movably disposed in the receiving cavity 23 and is configured to lock the handrail assembly 20 to the retrieval opening 12 so that the handrail assembly 20 blocks the retrieval opening 12. The unlocking member 40 is movably disposed on the handrail assembly 20 and elastically abuts against the locking assembly 30. The unlocking member 40 is used to drive the locking assembly 30 to move in a first direction to unlock the handrail assembly 20 from the retrieval opening 12.

[0065] This application provides a handrail locking device in which an unlocking member 40 elastically abuts against a locking component 30. The unlocking member 40 can directly drive the locking component 30 to unlock, eliminating the need for an additional transmission component between the unlocking member 40 and the locking component 30. This simplifies the structure of the handrail locking device, reduces the number of parts, lowers production complexity, helps save production costs, improves operational stability, and also helps reduce problems such as aging, wear, and noise of parts, thereby improving vehicle quality and enhancing the user experience.

[0066] In this example, the first direction reference Figure 3 The arrow X in the diagram indicates the direction.

[0067] refer to Figure 3 and Figure 4 As shown, the storage box 10 is disposed on the door interior panel 50, and a storage cavity 11 is formed inside the storage box 10. The storage box 10 has an access opening 12 that communicates with the storage cavity 11. The armrest assembly 20 is rotatably connected to the storage box 10, and the armrest assembly 20 moves between a first position that covers the access opening 12 and a second position that exposes the access opening 12.

[0068] In some embodiments of this application, the storage box 10 and the door interior panel 50 can be an integrally connected structure, or they can be detachably connected to the door interior panel 50 by screws, clips, or other connectors to prevent the storage box 10 from shaking relative to the door interior panel 50. The storage box 10 forms a storage cavity 11 inside, which is used to store items. Passengers can retrieve or place items through a retrieval opening 12, which may be located at the top of the storage cavity 11.

[0069] Figure 1 The image shows the first position of the armrest assembly 20 obstructing the access opening 12. Figure 2 The image shows the armrest assembly 20 in its second position, exposing the retrieval opening 12. The armrest assembly 20 can be rotatably connected to the top of the storage box 10. When the armrest assembly 20 is in its first position, obscuring the retrieval opening 12, it closes the opening, improving the privacy of stored items and supporting the driver's or passenger's arm, providing a comfortable armrest. When the armrest assembly 20 is in its second position, exposing the retrieval opening 12, it facilitates the driver's or passenger's access to items through the opening 12.

[0070] refer to Figure 1 and Figure 3As shown, the locking component 30 is configured to lock the armrest assembly 20 in the retrieval opening 12. Specifically, the locking component 30 locks the armrest assembly 20 in a first position, causing the armrest assembly 20 to block the retrieval opening 12. This prevents accidental movement of the armrest assembly 20 that could open the retrieval opening 12, improving the stability of the armrest assembly 20 in the first position. Furthermore, when encountering bumps during driving, it facilitates the gripping of the armrest assembly 20 by passengers, preventing it from tipping over and providing stable support.

[0071] This application provides an armrest locking device, in which the locking component 30 is movably disposed inside the armrest component 20, which saves interior space, improves the convenience and safety of use, and enables switching between armrest function and storage function to meet different usage needs.

[0072] In some embodiments of this application, reference is made to Figure 3 and Figure 5 As shown, the storage box 10 has a lock hole 13, and the locking assembly 30 includes a locking bar 31 and a locking tongue 32 connected to at least one end of the locking bar 31. The locking tongue 32 extends into the lock hole 13, thereby locking the armrest assembly 20 into the access opening 12. The opening of the lock hole 13 faces the locking tongue 32.

[0073] In some embodiments of this application, the locking bar 31 may be made of metal, providing sufficient strength and durability. It may be a strip-shaped structure extending in a straight line or a curve. The locking tongue 32 and the locking bar 31 may be an integral structure connected as one piece, or they may be separate structures connected by screws or bolts. The locking bar 31 has a simple structure, achieving low cost.

[0074] refer to Figure 5 As shown, in order to facilitate the insertion of the latch 32 into the lock hole 13, the latch 32 has a guide slope 321 to facilitate the insertion of the latch 32 into the lock hole 13.

[0075] In some embodiments of this application, reference is made to Figure 3 , Figure 5 and Figure 6 As shown, the handrail assembly 20 includes a lower handrail shell 21 and an upper handrail shell 22 connected to each other. A receiving cavity 23 is formed between the lower handrail shell 21 and the upper handrail shell 22. A locking assembly 30 is slidably disposed in the receiving cavity 23. A locking tongue 32 extends out of the receiving cavity 23 and extends into the lock hole 13 along a first direction. The locking tongue 32 is inserted into the lock hole 13. The blocking effect of the side wall of the lock hole 13 on the locking tongue 32 achieves the effect of locking the handrail assembly 20 in the access opening 12, thereby preventing the handrail assembly 20 from moving accidentally.

[0076] In some embodiments of this application, the locking component 30 moves within the receiving cavity 23 along a first direction and in the opposite direction. To guide the sliding of the locking component 30 within the receiving cavity 23, a groove extending along the first direction is provided within the receiving cavity 23, and a slider is provided on the locking rod 31. By sliding the slider along the groove, the sliding direction of the locking component 30 within the receiving cavity 23 is guided, which can effectively prevent the locking component 30 from becoming misaligned and stuck, and ensure the smoothness of the sliding of the locking component 30 along the first direction.

[0077] In some embodiments of this application, reference is made to Figure 3 As shown, the lower armrest shell 21 and the upper armrest shell 22 can be connected by screws or bolts, or by snap-fit ​​connections, so that a receiving cavity 23 is formed between the lower armrest shell 21 and the upper armrest shell 22.

[0078] In some embodiments of this application, reference is made to Figure 3 As shown in the embodiment of this application, a handrail locking device further includes a reset member 60, which is disposed between the unlocking member 40 and the locking component 30. The two ends of the reset member 60 elastically abut against the unlocking member 40 and the locking component 30, respectively.

[0079] When the driver or passenger stops operating the unlocking member 40, for example by pressing the unlocking member 40, the reset member 60 is elastically compressed to store force. Under the action of its own elastic force, the reset member 60 pushes the unlocking member 40 to move towards the outside of the armrest assembly 20 in a direction opposite to the first direction, that is, pushes the unlocking member 40 to move in the -X direction, thereby resetting the unlocking member 40.

[0080] In some embodiments of this application, the reset member 60 may be a compression spring, an elastic sleeve, or a spring sheet, etc.

[0081] In some embodiments of this application, reference is made to Figure 3 and Figure 4 As shown, the unlocking member 40 is slidably disposed on the handrail assembly 20 along the first direction. The unlocking member 40 includes an operating part 41 and a connecting post 42 connected to each other. The operating part 41 extends out of the handrail assembly 20, and the connecting post 42 extends into the receiving cavity 23. The reset member 60 is sleeved on the connecting post 42.

[0082] In some embodiments of this application, the operating part 41 and the connecting column 42 can be an integrally connected structure, for example by injection molding. The driver or passenger can operate the unlocking part 40, for example by pressing the operating part 41, so that the operating part 41 drives the connecting column 42 to move, thereby pushing the locking rod 31 to unlock.

[0083] In some embodiments of this application, one of the lower armrest shell 21 and the upper armrest shell 22 is provided with a guide hole 212, and the operating part 41 is movably disposed in the guide hole 212. Alternatively, both the lower armrest shell 21 and the upper armrest shell 22 are provided with half holes, and the half holes in the lower armrest shell 21 and the upper armrest shell 22 together form the guide hole 212. The guide hole 212 guides the movement of the operating part 41 along the first direction.

[0084] refer to Figure 3 and Figure 5 As shown, in order to prevent the operating part 41 from completely disengaging from the guide hole 212, a limiting part is provided at the end of the guide hole 212 away from the receiving cavity 23, and a boss is provided on the edge of the operating part 41. By having the boss provided on the edge of the operating part 41 abut against the limiting part, the operating part 41 can be prevented from completely disengaging from the guide hole 212, thus ensuring the stability of the unlocking member 40.

[0085] In some embodiments of this application, the locking assembly 30 further includes an elastic element 33, which is disposed on the side of the locking rod 31 facing away from the unlocking member 40, and elastically abuts against the inner wall of the locking rod 31 and the receiving cavity 23. The elastic element 33 is used to keep the locking rod 31 in a first position when the driver or passenger stops operating the unlocking member 40, that is, to keep the locking tongue 32 extended into the lock hole 13, thereby stably locking the armrest assembly 20 to the access opening 12.

[0086] In some embodiments of this application, the elastic element 33 may be a compression spring, an elastic sleeve, or a spring sheet, etc.

[0087] When the driver or passenger operates the unlocking component 40, for example by pressing it, the connecting post 42 of the unlocking component 40 pushes the locking rod 31 to move in the first direction, and the locking tongue 32 retracts from the lock hole 13, thus unlocking the armrest assembly 20. At this time, the armrest assembly 20 rotates relative to the storage box 10, moving from the first position to the second position where the retrieval opening 12 is exposed. The elastic element 33 is compressed by the locking rod 31 to store elastic force. When the driver or passenger stops pressing the unlocking component 40, the reset component 60, under its own elastic force, pushes the unlocking component 40 to move outward in the opposite direction to the first direction towards the armrest assembly 20, so that the unlocking component 40 no longer pushes the locking rod 31. At this time, the elastic element 33, under its own elastic force, pushes the locking rod 31 to move in the opposite direction to the first direction towards the side closer to the unlocking component 40, so that the locking tongue 32 is inserted into the lock hole 13, thus achieving the effect of stably locking the armrest assembly 20 in the first position, preventing the armrest assembly 20 from rotating relative to the storage box 10, and improving the stability of the armrest assembly 20 in supporting the driver's or passenger's arm.

[0088] The handrail locking device provided in this application embodiment has a simple structure of locking component 30 and unlocking component 40. By operating the unlocking component 40, for example by pressing the unlocking component 40, the connecting post 42 of the unlocking component 40 pushes the locking rod 31 to move in the first direction toward the side away from the unlocking component 40, thereby unlocking. The unlocking action is simple and efficient, without the need for complex transmission components, which helps to reduce the failure rate and improve the stability of use.

[0089] In some embodiments of this application, the locking rod 31 has a positioning post 311 on the side opposite to the unlocking member 40, and the elastic member 33 is sleeved on the positioning post 311. This structure can prevent the elastic member 33 from falling off and improve the stability of the installation of the elastic member 33. The number of positioning posts 311 can be one, or two or three distributed at intervals along the length direction of the locking rod 31.

[0090] In this example, the length direction of the locking lever 31 is also the extension direction of the locking lever 31. The extension direction of the locking lever 31 is along the second direction, as shown in the reference. Figure 3 The arrow Y in the diagram indicates the direction.

[0091] In some embodiments of this application, reference is made to Figure 3 As shown, both ends of the locking rod 31 are provided with locking tongues 32, and the extension direction of the locking tongues 32 forms an angle with the extension direction of the locking rod 31. Both ends of the storage box 10 are provided with lock holes 13. The positions of the locking tongues 32 correspond one-to-one with the positions of the lock holes 13. Providing two locking tongues 32 can improve the stability of the armrest assembly 20 locked in the storage box 10 and improve the uniformity of force on the armrest assembly 20 when gripping it.

[0092] In some embodiments of this application, the angle between the extension direction of the latch 32 and the extension direction of the locking bar 31 can be 89°, 90°, 92°, etc.

[0093] In some embodiments of this application, the axis of rotation of the armrest assembly 20 relative to the storage box 10 is parallel to the extension direction of the locking lever 31, and the unlocking member 40 is disposed on the side of the armrest assembly 20 facing the door interior panel 50. This structure can effectively prevent the driver and passengers from accidentally touching the unlocking member 40, causing the armrest assembly 20 to unlock from the first position.

[0094] In some embodiments of this application, the extension direction of the locking rod 31 is consistent with the length direction of the armrest assembly 20, and the axis of rotation of the armrest assembly 20 relative to the storage box 10 is parallel to the length direction of the armrest assembly 20, enabling the armrest assembly 20 to rotate around its own length direction, thus allowing the armrest assembly 20 to move between a first position that obstructs the retrieval opening 12 and a second position that exposes the retrieval opening 12. This structure results in a smaller space occupied by the rotational movement of the armrest assembly 20, facilitating operation.

[0095] In some embodiments of this application, reference is made to Figure 4 and Figure 7 As shown, a hinge seat 211 is provided on one side of the lower armrest shell 21 in the width direction. There can be two hinge seats 211, which are located near the two ends of the lower armrest shell 21. The storage box 10 is provided with hinge members at both ends. The hinge members are adapted to the hinge seat 211. Through the connection between the hinge members and the hinge seat 211, the armrest assembly 20 can rotate around its own length direction.

[0096] Of course, in other possible embodiments, the armrest assembly 20 can also rotate around its own width direction, and the extension direction of the locking rod 31 is consistent with the length direction of the armrest assembly 20, so as to realize the movement of the armrest assembly 20 between the first position of blocking the retrieval opening 12 and the second position of exposing the retrieval opening 12, and the locking effect of the armrest assembly 20.

[0097] In some other possible embodiments of this application, the unlocking member 40 may also be threadedly connected to the armrest assembly 20. The unlocking member 40 may be rotatably configured relative to the armrest assembly 20. While the unlocking member 40 rotates relative to the armrest assembly 20, it also pushes the locking assembly 30 along the first direction to unlock the locking assembly 30. When the direction of the unlocking member 40's rotation relative to the armrest assembly 20 is changed, the unlocking member 40 stops pushing the locking assembly 30. Under the elastic force of the elastic member 33, the locking rod 31 moves toward the unlocking member 40, so that the locking tongue 32 remains extended into the lock hole 13, achieving a stable locking effect.

[0098] The handrail locking device provided in this application embodiment has a simple structure for the locking component 30 and the unlocking component 40, and does not require complex transmission components. While reducing costs, it also reduces the number of parts. Due to the reduction in the number of parts, the failure rate is reduced, and problems such as wear and aging are significantly reduced compared to traditional structures, thus ensuring service life.

[0099] Secondly, this application embodiment also provides a car door armrest, including: a storage box 10 and the above-mentioned armrest locking device.

[0100] In some other possible embodiments of this application, the storage box 10 forms a storage cavity 11 inside, and the storage box 10 has an opening 12 that communicates with the storage cavity 11. The storage cavity 11 can be used to place various small items. The armrest locking device is set on the storage box, and the armrest assembly 20 can be used to place the arm, so that the arm can be effectively rested and not become sore, numb, or stiff.

[0101] When no items are being placed or removed, the locking component 30 locks the armrest component 20 to the retrieval opening 12, so that the armrest component 20 stably blocks the retrieval opening 12, thereby closing the retrieval opening 12 and preventing items stored in the storage cavity 11 from flying out and causing injury.

[0102] Thirdly, embodiments of this application also provide a vehicle, including: a vehicle body and the aforementioned door armrest. The vehicle body includes a door, the door includes a door interior panel 50, and the aforementioned door armrest is disposed on the door interior panel 50. The vehicle body refers to existing structures and will not be described in detail here.

[0103] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.
