Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a flip-top mechanism for automotive armrest box covers. Background Technology

[0002] A car armrest is a car accessory installed between two seats. Modern car armrests also include storage functions, such as storing small items like drinks and water cups, allowing the driver or passengers to easily access these items when needed. Structurally, a car armrest basically consists of a storage box and a conveniently opened lid that closes onto the opening of the box.

[0003] Regarding the opening and closing operation of the trunk lid relative to the trunk body, existing technologies, such as CN218661593U, disclose an automobile, an automobile armrest box, and its lid assembly. The lid of this armrest box uses a lid assembly to achieve the opening and closing operation relative to the trunk body. This lid assembly includes a power supply, a first electromagnet, and a second electromagnet. Based on this structure, the opening and closing operation of the lid is achieved through electronic control. Although the operation is convenient, it relies on a power source. Furthermore, for structures using power control, in the event of a power outage, such as when the vehicle is stopped and power is no longer supplied, the armrest box lid may fail to open or close properly. In addition, the overall cost of lid assemblies using electronic control is relatively higher than that of mechanically operated lid assemblies. Moreover, the production costs vary depending on the vehicle's class; therefore, for some lower-class vehicles, armrest boxes with relatively high production costs may not meet their usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for flipping up the armrest box cover of an automobile, thereby solving the technical problem of reducing the overall cost of the mechanism.

[0005] The flip-top mechanism for the armrest box cover of this utility model is implemented as follows:

[0006] A flip-top mechanism for a car armrest box cover includes: a pair of locking holes formed in the body of the car armrest box for mating with one end of one of a pair of opposing side edges perpendicular to the direction of travel of the car, a pair of pins provided on the cover for insertion into the pair of locking holes one by one, and a drive structure connected to the pair of pins for driving the pins to adjust their state of entering and exiting the locking holes.

[0007] In optional embodiments of this utility model, the driving structure includes a pair of pull plates that are connected one-to-one with a pair of pins, a movable rod that is connected to the pair of pull plates, a push block at one end of the movable rod, and an elastic element at the end of the movable rod away from the push rod.

[0008] In an optional embodiment of this utility model, each pull plate includes an arc-shaped body, a connector integrally formed on the arc-shaped body for connecting the pin shaft, and an L-shaped connector integrally formed on the arc-shaped body for connecting the movable rod.

[0009] In an optional embodiment of this utility model, the driving structure further includes a limiting seat disposed on the box cover and movably connected one-to-one with a pair of pull plates in an arc-shaped body; and

[0010] The arc-shaped main body is provided with a connecting ear for movably connecting with the limiting seat, and the limiting seat is provided with a connecting shaft for connecting with the connecting ear, and the connecting ear and the connecting shaft are rotatably engaged.

[0011] In an optional embodiment of this utility model, the box cover is further provided with at least a pair of limiting plates located on both sides of the movable rod along its direction of movement to limit the linear movement trajectory of the movable rod on the box cover.

[0012] In an optional embodiment of this invention, the elastic element is a spring.

[0013] In an optional embodiment of this utility model, the driving structure further includes at least a pair of limiting blocks disposed on the lid and located on both sides of the pusher's direction of movement, for defining the linear motion trajectory of the pusher on the lid; and

[0014] The pair of limiting blocks and push blocks slide together.

[0015] In an optional embodiment of this utility model, the drive structure further includes a locking component disposed between the movable rod and the housing;

[0016] The locking assembly includes a support plate disposed on the end face of the housing facing the lid, a stop seat disposed on the end face of the support plate facing the lid, and a stop strip with one end disposed on the movable rod and the other end adapted to abut against the stop seat; wherein

[0017] The stop bars are arranged in a structure that is inclined toward one side of the box relative to the movable rod;

[0018] The movable rod is provided with a hollow movable groove suitable for accommodating the stop bar, and the box cover is provided with a clearance groove suitable for the stop bar to pass through;

[0019] The end face of the stop bar facing the stop seat has a protrusion for abutting against the stop seat.

[0020] In an optional embodiment of this utility model, the connector has a connecting hole for a connecting pin, and the connecting hole is an oblong hole; and

[0021] The long inner diameter of the waist-shaped hole extends perpendicular to the direction of vehicle travel. The pin is connected to the waist-shaped hole via an L-shaped adapter and can move along the long inner diameter of the waist-shaped hole.

[0022] In an optional embodiment of this utility model, the arc-shaped body is further provided with an L-shaped hook to support the pin from the end of the pin toward the housing.

[0023] By adopting the above technical solution, this utility model has the following beneficial effects: The flip-top mechanism for automotive armrest box covers utilizes a lock hole and pin to switch between locking and unlocking states of the cover and body. This structure does not rely on a power source, resulting in relatively low production and installation costs. Furthermore, for cases where the pin and lock hole are connected via a simple plug-in joint, only a linear movement of the pin is needed to adjust its position in and out of the lock hole, making the overall operation simple and labor-saving.

[0032] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] Please see Figures 1 to 7 As shown, this embodiment provides a hinged mechanism for a car armrest box cover, including a pair of locking holes 4 formed in the body of the car armrest box for engaging with one end of one of the two opposing side edges of the opening 21 of the cover, which is perpendicular to the direction of car travel; a pair of pins 3 provided on the cover 1, adapted to be inserted one-to-one into the pair of locking holes 4; and a drive structure that connects the pair of pins 3 one-to-one to drive the pins 3 to adjust their position in and out of the locking holes 4. It should be noted that the direction of car travel referred to in this embodiment refers to the direction in which the car is traveling forward or backward along the road in its normal state. Regarding the opening 21 of the cover 1 relative to the body of the car armrest box, the opening and closing of the cover 1 and the body can be formed by one of the two side edges of the opening 21 perpendicular to the direction of the car's travel, or the opening and closing of the cover 1 and the body can be formed by the two side edges of the opening 21 perpendicular to the direction of the car's travel. This embodiment does not make an absolute limitation on this. The flip-top mechanism for the car armrest box cover in this embodiment is used to switch the opening 21 of the cover 1 and the body to be in an open or closed state along the side edge perpendicular to the direction of the car's travel.

[0034] More specifically, each drive structure includes a pair of pull plates connected to a pair of pins 3 one-to-one, a movable rod 52 connecting the pair of pull plates, a push block 53 at one end of the movable rod 52, and an elastic element 55 at the end of the movable rod 52 opposite to the push rod. In other words, one drive structure simultaneously drives a pair of pins 3, causing them to move synchronously. Furthermore, during the operation of the drive structure, the movement directions of the pair of pins 3 are opposite. This design is because the two locking holes 4 into which the pair of pins 3 are respectively inserted are located on a pair of opposite side edges of the open opening 21, perpendicular to the direction of vehicle travel. Therefore, the opposite movement directions of the pair of pins 3 are necessary to maintain the same engagement state between the pair of pins 3 and their corresponding locking holes 4.

[0035] Specifically, a person's finger can push the push block 53, causing it to push the movable rod 52. During the linear translational movement of the movable rod 52, a pair of pull plates will simultaneously deform, causing the pins 3 connected to the pair of pull plates to move parallel to the direction of the car's travel. This allows the pair of pins 3 on the same side of the push block 53 to simultaneously disengage from their respective lock holes 4, thus allowing the lid 1 to flip towards the side away from the push block 53, achieving the opening effect of the lid 1 relative to the opening 21. During this process, the elastic element 55 will be compressed and deformed. When the pushing force of the finger on the push block 53 disappears, the movable rod 52, pull plates, and pins 3 will all return to their original positions. It should be noted that the above operation can be used to open the lid 1 relative to the opening 21 of the box body 2, and also to close the lid 1 relative to the opening 21 of the box body 2. When closing the lid 1 relative to the opening 21, the push block 53 needs to be pushed first, and then the elastic force of the elastic element 55 is used to allow the pins 3 to enter the lock holes 4.

[0036] More specifically, each pull plate includes an arc-shaped body 511, a connector 512 integrally formed on the arc-shaped body 511 for connecting the pin 3, and an L-shaped connector 513 integrally formed on the arc-shaped body 511 for connecting the movable rod 52.

[0037] It is also necessary to explain that the drive structure in this embodiment includes a limiting seat 57 located on the cover 1 and movably connected to a pair of pull plates in a one-to-one manner; and a connecting ear 59 on the arc-shaped body 511 for movably connecting with the limiting seat 57, and a connecting shaft on the limiting seat 57 for connecting with the connecting ear 59, wherein the connecting ear 59 and the connecting shaft are rotatably engaged. The design of the limiting seat 57 here allows the pull plate to rotate slightly around the limiting seat 57 under the action of the movable rod 52, thereby converting the motion of the movable rod 52 into the rotation of the pull plate around the limiting seat 57, and ultimately realizing the linear motion of the pin 3 along the direction of vehicle travel. Based on this purpose, it should be noted that the connecting head 512 and the pin 3 in this embodiment have the following structural design:

[0038] Firstly, the connector 512 has a connecting hole 61 for connecting the pin 3. This connecting hole 61 is an oblong hole, with its long inner diameter extending perpendicular to the vehicle's travel direction. The pin 3 is connected to the oblong hole via an L-shaped adapter 62 and can move along the long inner diameter of the oblong hole. This structure allows the pin 3 to move parallel to the vehicle's travel direction when the movable rod 52 moves perpendicular to the vehicle's travel direction. Furthermore, the arc-shaped body 511 is also equipped with an L-shaped hook 63 to support the pin 3 from the end facing the housing 2, thereby preventing the L-shaped adapter 62 connected to the pin 3 from detaching from the oblong hole.

[0039] In addition, for the purpose of limiting the movement trajectory of the movable rod 52, so that the movement trajectory of the movable rod 52 on the box cover 1 is accurate and reliable, in this embodiment, the box cover 1 is also provided with at least a pair of limiting plates 71 on both sides of the movable rod 52 along its movement direction to limit the linear movement trajectory of the movable rod 52 on the box cover 1.

[0040] In one optional case, the elastic element 55 used in this embodiment is a spring. In order to make the spring accurately stretch and deform along the moving direction of the moving rod 52 under the pushing force of the moving rod 52, the end of the moving rod 52 facing the spring in this embodiment is also provided with a protrusion suitable for insertion into the spring. Here, a stop 99 is also provided on the cover 1 to abut the end of the spring away from the moving rod 52, so that the spring can be compressed and deformed synchronously with the linear movement of the moving rod 52.

[0041] In one optional embodiment, the drive structure further includes at least a pair of limiting blocks disposed on the lid 1 and located on both sides of the push block 53's direction of movement, for defining the linear movement trajectory of the push block 53 on the lid 1; and a pair of limiting seats 57 that slide in engagement with the push block 53. This structure ensures that the overall push block 53 moves precisely and reliably during the process of being pushed by a finger, without any deviation. Based on this structure, this embodiment can also be improved as follows: the pair of limiting blocks enclose a limiting member 72, which has a hollow cavity for accommodating the push block 53. A groove is formed on the inner wall of this cavity that slides in engagement with the push block 53, allowing the push block 53 to slide along the groove when pushed by a finger.

[0042] To prevent the push block 53 on the lid 1 from being accidentally triggered and causing the lid 1 to open relative to the opening 21 of the box body 2, the drive structure used in this embodiment also includes a locking component located between the movable rod 52 and the box body 2. The push block 53 works in conjunction with the locking component to prevent the push block 53 from accidentally opening the lid 1.

[0043] Regarding the locking assembly used in this embodiment, for example, in one optional case, it includes a support plate 91 disposed on the end face of the box 2 facing the box cover 1, a stop seat 92 disposed on the end face of the support plate 91 facing the box cover 1, and a stop strip 93 with one end disposed on the movable rod 52 and the other end adapted to abut against the stop seat 92; although the support plate 91 is located in the space of the opening 21, it will not affect the normal loading and unloading of items in the opening 21.

[0044] Based on the above structure, it is also necessary to explain that the stop bar 93 is distributed in an inclined manner towards the box body 2 relative to the movable rod 52; the movable rod 52 is provided with a hollow movable groove 94 suitable for accommodating the stop bar 93, and the box cover 1 is provided with a clearance groove 98 suitable for the stop bar 93 to pass through; the end face of the stop bar 93 facing the stop seat 92 is provided with a protrusion 95 for abutting against the stop seat 92. The clearance groove 98 here allows the protrusion 95 on the stop bar 93 to pass through the box cover 1 and achieve abutting engagement with the stop seat 92, while the design of the movable groove 94 allows the end of the stop bar 93 with the protrusion 95 to be slightly tilted towards the side away from the box body 2, thereby releasing the abutting state between the protrusion 95 and the stop seat 92. Furthermore, in order to better achieve the effect of preventing the box cover 1 from opening when the push block 53 is accidentally touched, the protrusion 95 abuts against the stop seat 92 when the push block 53 is not pushed.

[0045] In this embodiment, the locking assembly is designed so that when the pin 3 is inserted into the lock hole 4, the protrusion 95 presses against the stop seat 92. Since the stop strip 93 is located within the movable rod 52, if a finger needs to push the push block 53 to move the movable rod 52, the stop seat 92's contact with the protrusion 95 prevents the push block 53 from moving even with slight accidental contact. This avoids accidentally opening the lid 1. Only when the pushing force on the push block 53 is sufficient to slightly lift the end of the stop strip 93 with the protrusion 95 away from the box body 2, thus releasing the pushing contact between the protrusion 95 and the stop seat 92, can the movable rod 52 smoothly move linearly on the lid 1 under the action of the push block 53, thereby driving the pin 3 to move synchronously.
