Description

Technical Field

[0001] This invention relates to the field of armrest boxes, and more specifically to a double-opening armrest box for automobiles. Background Technology

[0002] A car armrest, also known as a center console, is an automotive accessory installed between two seats and belongs to the car's interior system. Its ergonomic design aims to provide a place for the driver's arm to rest during long drives, preventing soreness, numbness, and stiffness. To enhance functionality, storage compartments are incorporated within the armrest for storing small items. Existing armrests typically feature two hinged covers, both rotating and mounted on the body of the armrest. However, in actual use, vehicle vibrations can cause the covers to wobble and accidentally unlock. Furthermore, existing double-opening armrests suffer from a delay in unlocking the covers, meaning they cannot open simultaneously when the driver or passenger unlocks the armrest. To address these issues, this invention proposes a double-opening automotive armrest. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: a car double-opening armrest box with simple structure, convenient operation, and capable of unlocking both covers at the same time and locking reliably.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a double-opening armrest box for automobiles, comprising a box base fixed to a box body, with armrest covers hinged to both sides of the box base for opening or closing the armrest box. A locking mechanism is provided within the armrest covers, comprising a first locking tongue and a second locking tongue laterally slidably disposed within the armrest covers. The first locking tongue is movably protruding from one end of the armrest covers, and the second locking tongue comprises a sliding rod and a locking rod, the locking rod being coaxially disposed with the first locking tongue and movably protruding from the other end of the armrest covers. At one end, a linkage shaft is provided between the sliding rod and the first locking tongue. The linkage shaft is hinged to the first locking tongue and the sliding rod respectively through linkage members on both sides. A compression torsion spring is also provided inside the armrest cover to make the first locking tongue and the second locking tongue have a tendency to move outward from the armrest cover. The two ends of the housing base are respectively provided with lock holes corresponding to the first locking tongue and the locking rod. The front end of the housing base is also provided with an unlocking component. The unlocking component includes an unlocking member, which can drive the two first locking tongues on both sides of the housing base to retract into the corresponding armrest cover at the same time.

[0005] Furthermore, the unlocking component also includes a pressing member that slides in conjunction with the housing base. The lower end of the pressing member is provided with a first wedge-shaped portion. The unlocking member is laterally slidably disposed at the front end of the housing base. The unlocking member is provided with a second wedge-shaped portion corresponding to the first wedge-shaped portion. The unlocking member is also provided with two unlocking protrusions, and the unlocking member can extend into the corresponding lock holes. The advantage is that the cooperation of the first and second wedge-shaped portions enables the unlocking member to move when the user presses the pressing member, thereby achieving unlocking. The structure is simple and easy to use. At the same time, the two unlocking protrusions extending into the corresponding lock holes ensure reliable unlocking and synchronous unlocking of the two first locking tongues.

[0006] Preferably, the front end of the housing is provided with a fixed seat, the unlocking component is laterally slidably disposed within the fixed seat, the fixed seat has a pressing hole, the pressing component is vertically movably inserted into the pressing hole, the fixed seat is also provided with an auxiliary plate, the unlocking component is provided with a baffle corresponding to the auxiliary plate, a compression spring is provided between the auxiliary plate and the baffle, and the upper part of the unlocking component is also provided with an anti-detachment plate that cooperates with the fixed seat; the advantage is that the fixed seat ensures the reliability of the lateral movement of the unlocking component, while the cooperation of the auxiliary plate, baffle and compression spring ensures the reliability of the unlocking component's reset, and the anti-detachment plate effectively prevents the assembled unlocking component from being driven away from the fixed seat by the compression spring, ensuring the reliability of the reset.

[0007] Preferably, the unlocking assembly further includes a pressing plate and a pressing member vertically movably disposed at the front of the housing base. A connecting plate is provided at the front end of the housing base, and the unlocking member is hinged to the connecting plate. The connecting plate is also provided with an auxiliary torsion spring, which is used to drive the unlocking member to move away from the first latch. The connecting plate is also hinged with a pressing plate, which presses down on the unlocking member to drive the unlocking member to move towards the first latch. The lower end of the pressing member presses down on the pressing plate. The advantage is that, through the cooperation of the connecting plate, pressing plate, auxiliary torsion spring and unlocking member, when the user presses the pressing member, the pressing plate is driven to press down on the unlocking member, thereby driving the unlocking member to simultaneously unlock the two corresponding first latches, ensuring the reliability of unlocking.

[0008] Furthermore, the unlocking component includes two identical unlocking plates. Each unlocking plate has an unlocking protrusion that can be movably inserted into the lock hole at its upper end. The unlocking plates are hinged to the front of the connecting plate. One end of the pressing plate is hinged to the rear of the connecting plate, and the other end extends to the front end of the connecting plate and is located between the two unlocking plates. The pressing plate has pressing parts corresponding to the two unlocking plates. The advantage is that by setting the unlocking component in the form of two unlocking plates, and by synchronously pressing through the pressing parts on the pressing plate, and with the pressing plate located between the two unlocking plates, the synchronicity of unlocking the two handrail covers is ensured while improving the ease of assembly.

[0009] Preferably, the handrail cover includes a lower base, and the locking mechanism is disposed within the lower base. Positioning holes are provided at both ends of the lower base, through which the first locking tongue and locking rod can movably pass. Two sets of sliding support groups are also provided within the lower base, with the first and second locking tongues slidingly engaging with their respective sliding support groups. The advantage is that the sliding support groups can support the first and second locking tongues and ensure the stability of their sliding movement.

[0010] Furthermore, a fixing post is also provided inside the lower base, and the linkage shaft is rotatably sleeved on the outside of the fixing post. The fixing post is also sleeved with a reset torsion spring for driving the linkage shaft to reset. The advantage is that the cooperation between the fixing post and the linkage shaft can ensure the stability of the linkage shaft rotation. At the same time, the reset torsion spring can further improve the reset reliability of the linkage shaft, that is, improve the reset locking ability of the first locking tongue and the second locking tongue, and prevent the armrest cover from being opened accidentally.

[0011] Preferably, a limiting rod is provided at the end of the locking rod away from the lock hole, and the first locking tongue is provided with a limiting part corresponding to the limiting rod; when the locking mechanism is in the unlocked state, the limiting part is close to or abuts against the limiting rod; the advantage is that the cooperation between the limiting plate and the limiting part can prevent the first locking tongue and the second locking tongue from excessively retracting, thereby avoiding the phenomenon that the first locking tongue and the second locking tongue cannot pop out after being fully retracted into the handrail cover plate.

[0012] Preferably, the armrest cover is hinged to the housing seat via a hinge shaft. The housing seat is provided with a hinge portion, and the hinge shaft passes through the hinge portion. The armrest cover is provided with support plates at both ends of the hinge shaft. A buffer sleeve is fitted at one end of the hinge shaft, and the buffer sleeve abuts against the corresponding support plate and hinge portion. A flipping torsion spring for driving the armrest cover to rotate is fitted on the outer side of the buffer sleeve. An auxiliary sleeve is fitted at the other end of the hinge shaft, and the auxiliary sleeve abuts against the corresponding support plate and hinge portion. The advantage is that the buffer sleeve and auxiliary sleeve can effectively ensure the gap between the support plate and the hinge portion to prevent the armrest cover from lateral swaying, reducing abnormal noise from the armrest cover during vehicle operation. At the same time, the buffer sleeve can effectively reduce the direct contact between the flipping torsion spring and the hinge shaft, thereby reducing frictional noise between the flipping torsion spring and the hinge shaft during the rotation of the armrest cover.

[0013] Furthermore, one of the two support plates is provided with an insertion hole, one end of which is sealed, and the other support plate is provided with a through hole. The hinge shaft passes through the through hole and is inserted into the insertion hole. The handrail cover is detachably provided with a bottom cover, and the bottom cover is provided with a fixing plate corresponding to the through hole. The fixing plate is used to restrict the axial movement of the hinge shaft. The advantage is that the support plate can support the hinge shaft to ensure its stability and strength; the one-end sealed insertion hole can prevent one end of the hinge shaft from protruding, and the fixing plate can block and limit the other end of the hinge shaft. Thus, the cooperation between the support plate and the fixing plate ensures the stability of the hinge shaft, reduces its axial position, avoids shaking, and further improves the flipping stability of the handrail cover.

[0014] Compared with existing technologies, this invention has the following advantages: the armrest box can be opened and closed by hinged armrest covers on both sides of the box base. The locking mechanism within the armrest cover locks the cover; the cooperation of the first locking tongue, second locking tongue, and linkage shaft locks both ends of the armrest cover, ensuring stability and preventing tilting or wobbling at one end, and effectively preventing accidental opening. Simultaneously, the unlocking component allows for the synchronous unlocking of both first locking tongues, ensuring the synchronous opening of both armrest covers and improving the user-friendliness and convenience of the armrest box.

The locking mechanism 3 includes a first locking tongue 3.1 and a second locking tongue 3.2 laterally slidable within the armrest cover 2. The first locking tongue 3.1 can movably extend through one end of the armrest cover 2. The second locking tongue 3.2 includes a sliding rod 3.21 and a locking rod 3.22. The locking rod 3.22 is coaxially arranged with the first locking tongue 3.1 and can movably extend through the other end of the armrest cover 2. A connection is established between the sliding rod 3.21 and the first locking tongue 3.1. A linkage shaft 3.3 is provided, which is hinged to the first locking tongue 3.1 and the sliding rod 3.21 on both sides through linkage components. A compression torsion spring 3.4 is also provided inside the armrest cover plate 2 to make the first locking tongue 3.1 and the second locking tongue 3.2 tend to move outward from the armrest cover plate 2. The two ends of the housing base 1 are respectively provided with lock holes 1.2 corresponding to the first locking tongue 3.1 and the locking rod 3.22. The front end of the housing base 1 is also provided with an unlocking component 4, which includes an unlocking component 4.1. The unlocking component 4.1 can drive the two first locking tongues 3.1 on both sides of the housing base 1 to retract into the corresponding armrest cover plate 2 simultaneously.

[0021] This design allows for the opening and closing of the armrest box via armrest covers 2 hinged to both sides of the box base 1. A locking mechanism 3 within the armrest covers 2 locks them in place. The cooperation of the first locking tongue 3.1, the second locking tongue 3.2, and the linkage shaft 3.3 locks both ends of the armrest covers 2, ensuring stability and preventing tilting or wobbling at one end, and effectively preventing accidental opening. Simultaneously, the unlocking component 4.1 within the unlocking assembly 4 allows for the simultaneous unlocking of both first locking tongues 3.1, ensuring the synchronous opening of both armrest covers 2 and improving the user-friendliness and convenience of the armrest box.

[0022] Example 2, as shown in the appendix Figure 2-10As shown, based on Embodiment 1, the unlocking component 4 further includes a pressing member 4.2, which slides with the housing base 1.

The unlocking member 4.1 is provided with a second wedge-shaped part 4.11 corresponding to the first wedge-shaped part 4.21. The unlocking member 4.1 is also provided with two unlocking protrusions 4.12, and the unlocking member can extend into the corresponding lock hole 1.2. More preferably, the front end of the housing base 1 is provided with a fixed base 4.3, the unlocking member 4.1 is slidably disposed in the fixed base 4.3, the fixed base 4.3 is provided with a pressing hole 4.31, the pressing member 4.2 is vertically movably inserted into the pressing hole 4.31, the fixed base 4.3 is also provided with an auxiliary plate 4.32, the unlocking member 4.1 is provided with a baffle 4.13 corresponding to the auxiliary plate 4.32, a compression spring 4.33 is provided between the auxiliary plate 4.32 and the baffle 4.13, and the upper part of the unlocking member 4.1 is also provided with an anti-detachment plate 4.14 that cooperates with the fixed base 4.3. The cooperation of the first wedge-shaped part 4.21 and the second wedge-shaped part 4.11 enables the unlocking part 4.1 to move when the user presses the pressing part 4.2, thereby achieving unlocking. The structure is simple and easy to use. At the same time, the two unlocking protrusions 4.12, after extending into the corresponding lock holes 1.2, ensure reliable unlocking and synchronous unlocking of the two first locking tongues 3.1. The fixed base 4.3 ensures the reliability of the lateral movement of the unlocking part 4.1. The cooperation of the auxiliary plate 4.32, the baffle 4.13, and the compression spring 4.33 ensures the reliability of the reset of the unlocking part 4.1. The anti-detachment plate 4.14 effectively prevents the assembled unlocking part 4.1 from being driven away from the fixed base 4.3 by the compression spring 4.33, ensuring the reliability of the reset.

[0023] Example 3, as attached Figure 11-16As shown, based on Embodiment 1, the unlocking assembly 4 further includes a pressing plate 4.7 and a pressing member 4.2 vertically movably disposed at the front of the housing base 1. A connecting plate 4.4 is provided at the front end of the housing base 1. The unlocking member 4.1 is hinged to the connecting plate 4.4. The connecting plate 4.4 is also provided with an auxiliary torsion spring 4.6, which is used to drive the unlocking member 4.1 to move away from the first locking tongue 3.1. The connecting plate 4.4 is also hinged to the pressing plate 4.7, which is pressed on top of the unlocking member 4.1 to drive the unlocking member 4.1 to move towards the first locking tongue 3.1. The lower end of the pressing member 4.2 is pressed on top of the pressing plate 4.7. More specifically, the unlocking component 4.1 includes two identical unlocking plates 4.5. Each unlocking plate 4.5 has an unlocking protrusion 4.12 that can be movably inserted into the lock hole 1.2 at its upper end. The unlocking plates 4.5 are hinged to the front of the connecting plate 4.4. One end of the pressing plate 4.7 is hinged to the rear of the connecting plate 4.4, and the other end extends to the front end of the connecting plate 4.4 and is located between the two unlocking plates 4.5. The pressing plate 4.7 has pressing parts 4.71 corresponding to the two unlocking plates 4.5. Through the cooperation of the connecting plate 4.4, the pressing plate 4.7, the auxiliary torsion spring 4.6, and the unlocking component 4.1, when the user presses the pressing element 4.2, the pressing plate 4.7 is driven to press down on the unlocking component 4.1, thereby driving the unlocking component 4.1 to simultaneously unlock the two corresponding first locking tongues 3.1, ensuring the reliability of unlocking. The present invention sets the unlocking component 4.1 in the form of two unlocking plates 4.5, and simultaneously presses the two first locking tongues 3.1 through the pressing part 4.71 on the pressing plate 4.7, and the pressing plate 4.7 is located between the two unlocking plates 4.5, which improves the ease of assembly while ensuring the synchronicity of unlocking the two handrail covers 2.

[0024] Based on Embodiment 1, the handrail cover 2 of the present invention includes a lower base 2.1 and an upper cover 2.2. The handrail cover 2 is formed by detachable lower base 2.1 and upper cover 2.2. The locking mechanism 3 is disposed in the lower base 2.1. Positioning holes 2.3 are provided at both ends of the lower base 2.1. The first locking tongue 3.1 and the locking rod 3.22 can move out of the corresponding positioning holes 2.3. Two sets of sliding brackets 2.4 are also provided in the lower base 2.1. The first locking tongue 3.1 and the second locking tongue 3.2 are respectively slidably engaged with the corresponding sliding brackets 2.4. The above-mentioned sliding brackets 2.4 can support the first locking tongue 3.1 and the second locking tongue 3.2 and ensure the stability of sliding translation. It is worth mentioning that a fixed post 2.5 is also provided in the lower base 2.1. The linkage shaft 3.3 is rotatably sleeved on the outside of the fixed post 2.5. The fixed post 2.5 is also sleeved with a return torsion spring 2.6 for driving the linkage shaft 3.3 to reset. The fixed post 2.5 and the linkage shaft 3.3 work together to ensure the stability of the rotation of the linkage shaft 3.3. At the same time, the reset torsion spring 2.6 can further improve the reset reliability of the linkage shaft 3.3, that is, improve the reset locking ability of the first locking tongue 3.1 and the second locking tongue 3.2, and prevent the armrest cover 2 from being opened accidentally.

[0025] Based on Embodiment 1, to ensure the reliability of the retraction of the first locking tongue 3.1 and the second locking tongue 3.2, a limiting rod 3.23 is provided at the end of the locking rod 3.22 away from the lock hole 1.2, and the first locking tongue 3.1 is provided with a limiting part 3.11 corresponding to the limiting rod 3.23. When the locking mechanism 3 is in the unlocked state, the limiting part 3.11 is close to or abuts against the limiting rod 3.23, thereby avoiding excessive retraction of the first locking tongue 3.1 and the second locking tongue 3.2, and avoiding the phenomenon that the first locking tongue 3.1 and the second locking tongue 3.2 cannot pop out after being fully retracted into the handrail cover plate 2.

[0026] Based on Embodiment 1, one side of the handrail cover 2 of the present invention is hinged to the housing base 1 via a hinge shaft 5. The housing base 1 is provided with a hinge part 1.1, and the hinge shaft 5 passes through the hinge part 1.1. The upper cover 2.2 of the handrail cover 2 is provided with support plates 2.7 located at both ends of the hinge shaft 5. A buffer sleeve 6 is sleeved on one end of the hinge shaft 5. The buffer sleeve 6 abuts against the corresponding support plate 2.7 and the hinge part 1.1. A flipping torsion spring 7 for driving the handrail cover 2 to flip is sleeved on the outside of the buffer sleeve 6. An auxiliary sleeve 8 is sleeved on the other end of the hinge shaft 5. The auxiliary sleeve 8 abuts against the corresponding support plate 2.7 and the hinge part 1.1. It is worth mentioning that one of the two support plates 2.7 is provided with an insertion hole, one end of which is sealed, while the other support plate 2.7 is provided with a through hole. The hinge shaft 5 passes through the through hole and is inserted into the insertion hole. The armrest cover 2 is detachably provided with a bottom cover 2.8, and the bottom cover 2.8 is provided with a fixing plate 2.81 corresponding to the through hole. The fixing plate 2.81 is used to restrict the axial movement of the hinge shaft 5. The buffer sleeve 6 and auxiliary sleeve 8 provided on the hinge shaft 5 can effectively ensure that the gap between the support plate 2.7 and the hinge part 1.1 prevents the armrest cover 2 from swaying laterally, reducing the abnormal noise of the armrest cover 2 during vehicle operation. At the same time, the buffer sleeve 6 can effectively reduce the direct contact between the flipping torsion spring 7 and the hinge shaft 5, thereby reducing the frictional abnormal noise between the flipping torsion spring 7 and the hinge shaft 5 during the flipping of the armrest cover 2. The support plate 2.7 can support the hinge shaft 5, effectively providing stability and strength to the hinge shaft 5; the sealed insertion hole at one end can prevent one end of the hinge shaft 5 from protruding, while the fixed plate 2.81 can block and limit the other end of the hinge shaft 5. Thus, the cooperation between the support plate 2.7 and the fixed plate 2.81 ensures the stability of the hinge shaft 5, reduces its axial position, avoids shaking, and further improves the flipping stability of the handrail cover 2.
