Description

Technical Field

[0001] This invention relates to the field of automotive armrest technology, and in particular to a double-sided flip-over interlocking structure and an automotive armrest having the same. Background Technology

[0002] Currently, there are many models of car control panel armrests on the market. Due to the convenience of accessing double-sided armrests, more and more car manufacturers are adopting the double-sided flip armrest structure. However, the double-sided flip armrest structure has the problem that both sides of the armrest can be opened simultaneously. That is, during the operation of the customer, if the buttons on one side are not reset, the other side of the armrest can be opened, and the entire armrest is in a detached state, which affects driving safety.

[0003] For example, Chinese patent CN115158167A discloses a left and right side-flipping armrest system assembly, including an armrest covering assembly, an armrest inner cover plate assembly, an armrest bracket assembly, and a frame assembly. The armrest covering assembly covers the armrest inner cover plate assembly, and the armrest inner cover plate assembly is screwed to the armrest bracket assembly via a cantilever linkage screw. The lower end of the armrest bracket assembly is snapped or screwed to the frame assembly. The armrest system can be flipped open by pressing the unlocking buttons on the left and right sides, which can facilitate the opening and use of both the driver and passenger. However, the armrest is detached from its main body, which affects the overall experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a double-sided flip-over interlocking structure and a car handrail incorporating it, wherein the two sides of the handrail can be interlocked to prevent simultaneous unlocking and opening.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A double-sided flip-up interlocking structure includes a base plate. The base plate has a pair of press-to-unlock structures that are interlocked and arranged opposite each other. Each press-to-unlock structure includes a button, a linkage rod, a locking pin, and a trigger for limiting the linkage rod. The button is set at the outer end of the linkage rod. The inner ends of the two linkage rods of the pair of press-to-unlock structures are arranged opposite each other. The locking pin and the linkage rod are linked together. The trigger is set on the base plate through a pin and a trigger spring. A linkage rod slot is provided at one end of the linkage rod corresponding to the trigger. A linkage rod reset spring is provided on the base plate corresponding to the linkage rod for resetting the linkage rod.

[0007] The substrate has a hollow button base, and the button is located inside the button base.

[0008] The locking pin is movably mounted on the base plate via a guide rail structure. The linkage rod is provided with an inclined groove, and the inner end of the locking pin is provided with a movable pin located in the inclined groove.

[0009] The trigger spring is a torsion spring, and the other end of the trigger is provided with a trigger pin for disengaging one end of the trigger from the connecting rod slot.

[0010] The linkage is movably mounted on the base plate via a guide structure.

[0011] The linkage is a plate structure, and the inner end of the plate structure is provided with a protrusion for limiting interference between a pair of linkages. The inner ends of the protrusions of the two linkages are arranged opposite to each other.

[0012] The trigger is a strip structure, and one end of the strip structure has a protruding locking block corresponding to the connecting rod slot.

[0013] A slot is provided between the linkage rod and the locking pin's linkage side and the protrusion, and the linkage rod return spring is located in the slot.

[0014] The linkage slot is located on the protruding part of the linkage.

[0015] A car handrail includes a base and a double-sided flip handrail disposed on the base. The double-sided flip handrail is provided with a double-sided flip interlocking structure, and the base is provided with a lock hole corresponding to the lock pin.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The dual-sided flip-over interlocking structure and the car armrest structure with it are reasonably designed. The dual-sided flip-over armrest buttons are designed as an interlocking structure, allowing only one side of the armrest to be in the unlocked state, avoiding the simultaneous unlocking and opening of both sides of the armrest, and improving driving safety.

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0030] like Figures 1 to 8 As shown, the dual-sided flip armrest button interlocking structure includes a base plate 1 and a pair of press-to-unlock structures disposed on the base plate that are interlocked and opposite to each other. The base plate and the pair of press-to-unlock structures form an interlocking assembly. The base plate is provided with mounting holes for mounting and fixing the assembly.

[0031] A pair of press-to-unlock structures are symmetrically arranged on the substrate 1. The substrate 1 is an integral plate structure. Both ends of the substrate are provided with side mounting holes. A middle mounting hole is provided on the substrate between the pair of press-to-unlock structures. The substrate is fixed by a set of mounting holes, which is stable and reliable. Furthermore, a protruding structure is provided corresponding to the middle mounting hole. The middle mounting hole is located on the top of the protruding structure. The protruding structure can improve the structural strength of the substrate.

[0032] The two push-to-unlock mechanisms are identical in structure, with interchangeable parts, which reduces production costs and simplifies assembly. The push-to-unlock mechanism on one side is described in detail below:

[0033] The one-sided press-to-unlock structure includes a button 3, a button base 2, a linkage rod 5, a locking pin 6, and a trigger 8 for limiting the linkage rod. The button base 2 is fixed to the side of the base plate, and the edge of the button base 2 is provided with a fixing ear. The button base is fixed to the base plate by screws passing through the fixing ear. The button base has a hollow structure, and the inner and outer ends of the button base are interconnected. The button 3 is movably disposed in the button base. The button is provided with a snap-lock to prevent it from falling out of the button base. A set of springs is provided on the button base corresponding to the button. The button can automatically reset after being pressed to unlock.

[0034] Button 3 is positioned at the outer end of the linkage rod, meaning the button is located at the inner end of the button base corresponding to the outer end of the linkage rod 5. Pressing the button moves the linkage rod 5. The inner ends of the two linkage rods of the pair of press-to-unlock structures are positioned opposite each other. The locking pin 6 and the linkage rod 5 are linked. The locking pin moves by moving the linkage rod to unlock the mechanism. The inner ends of the pair of linkage rods interfere with each other. One side of the press-to-unlock structure is in the unlocked state, while the other side cannot be unlocked due to the interference of the linkage rods. This prevents both sides of the armrest from unlocking simultaneously, improving driving safety.

[0035] The trigger is mounted on the base plate via a pin and trigger spring 9. A linkage rod slot is provided at one end of the trigger on the linkage rod, and a linkage rod reset spring for resetting the linkage rod is provided on the base plate corresponding to the linkage rod. When the one-sided press-to-unlock structure is in the unlocked state, the linkage rod of the one-sided press-to-unlock structure moves inward, and one end of its trigger will be locked into the linkage rod slot of the linkage rod, limiting the linkage rod. The linkage rod of the other side of the press-to-unlock structure cannot move to unlock.

[0036] Furthermore, the trigger spring is a torsion spring, which is located on the pin of the trigger. When the torsion spring passes through, the trigger always has a squeezing force on the linkage rod, which facilitates the smooth insertion of one end of the trigger into the linkage rod slot. Correspondingly, the other end of the trigger is provided with a trigger pin 10 for the trigger end to disengage from the slot. When the other end of the trigger contacts the trigger pin, the trigger will rotate around the pin, and one end of the trigger will disengage from the linkage rod slot, releasing the restriction on the linkage rod, and the linkage rod can be reset.

[0037] The linkage 5 is movably mounted on the base plate 1 via a guide structure. A pair of linkages with a press-to-unlock structure are arranged adjacent to each other, and the button on each side corresponds to the outer end of the linkage on that side. The locking pin is movably mounted on the base plate via a guide rail structure. The linkage has a groove, and the inner end of the locking pin has a movable pin located in the groove. The guide structure of the linkage and the guide rail structure of the locking pin are arranged perpendicularly. The movement of the linkage will cause the locking pin to extend and retract, thereby realizing unlocking and locking.

[0038] The guide rail structure of the locking pin 6 and the guide structure of the linkage rod are both located on the base plate. The guide rail structure of the locking pin 6 is located on one side of the linkage rod, and the guide structure of the linkage rod 5 is set on the other side of the linkage rod. The arrangement is reasonable and has little impact on the structural strength of the base plate. Furthermore, the pin and trigger are located on the same side of the linkage rod, resulting in a compact structure.

[0039] The linkage is a plate structure, with an extension at the inner end of the plate structure for limiting interference between a pair of linkages. The inner ends of the extensions of the two linkages are arranged opposite each other. The linkage slot is provided on the extension of the linkage. That is, one side of the linkage is the inclined groove side, and the other side of the linkage is the extension side. The linkage is an integral injection molded structure, which is compact and easy to mold.

[0040] A slot is provided between the linkage rod and the locking pin on the linkage side and the protrusion, and the linkage rod return spring 7 is located in the slot. After the end of the trigger disengages from the slot of the linkage rod, the linkage rod restriction is released. Through the action of the linkage rod return spring, the linkage rod will automatically return to its original position, releasing the linkage rod interference restriction on the other side of the press-to-unlock structure, that is, the button on the other side can be pressed to perform the unlocking operation.

[0041] The connecting rod has an outer positioning post in the slot for positioning the outer end of the connecting rod spring. The outer end of the connecting rod spring is sleeved on the outer positioning post. The base plate has a protrusion corresponding to the inner end of the connecting rod spring. The protrusion has an inner positioning post. The inner end of the connecting rod spring is sleeved on the inner positioning post. The structure is stable and reliable, and the structure is compact.

[0042] The trigger is a strip structure. One end of the strip structure has a protruding locking block corresponding to the connecting rod slot, and the other end of the strip structure is set with a trigger pin. The edges of the locking block are chamfered to facilitate locking into the connecting rod slot.

[0043] This invention relates to a car armrest, comprising a base and a double-sided flip-up armrest mounted on the base. The aforementioned double-sided flip-up interlocking structure assembly is disposed within the double-sided flip-up armrest, and the base has locking holes corresponding to the locking pins. Only one side of the double-sided flip-up armrest is allowed to be unlocked, preventing both sides of the armrest from unlocking simultaneously and improving driving safety.

[0044] like Figure 5 As shown, when the double-sided tilting handrails are in the closed state, the trigger disengages from the linkage rod slot, and the locking pin extends and is in the locked state.

[0045] like Figure 6 As shown, when one side of the double-sided handrail is in the open state, pressing the button pushes the linkage rod to move, causing the locking pin to retract and unlocking the handrail. When the linkage rod slot is in the trigger position, under the action of the trigger spring, one end of the trigger will enter the linkage rod slot, and the linkage rod will be locked and cannot be reset, that is, the locking pin remains in the retracted and unlocked state. When closing the handrail, when the trigger contacts the trigger pin, the trigger pin pushes the trigger away from the linkage rod slot, and the linkage rod resets under the action of the linkage rod spring. The linkage rod drives the pin to extend and lock the handrail, that is, the handrail closes.

[0046] like Figure 7 The following explains the principles of handrail unlocking and interlocking:

[0047] When the left button is pressed, the left linkage retracts, pushing the locking pin back and unlocking the armrest. When the linkage is in the unlocked position, the trigger springs upward, locking into the linkage's slot and preventing it from resetting. When the right button is pressed, the left linkage limits the right linkage, preventing it from unlocking properly. This interlocking structure solves the problem of simultaneous opening of both armrests. By designing the buttons on both armrests as an interlocking structure, only one side of the armrest is allowed to be unlocked, preventing both sides from opening simultaneously and improving driving safety.

[0048] like Figure 8 As shown, the principle of armrest closure is explained below:

[0049] When the handrail is closed, the trigger contacts the trigger pin on the base plate, and one end of the trigger disengages from the linkage rod slot. The linkage rod retracts under the action of the reset spring, pushing the locking pin back and closing the handrail; thus realizing the handrail closing action.

[0050] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.
