Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an armrest assembly with a cup holder. Background Technology

[0002] Due to limitations in the usage environment, the width (Y direction) of the small armrests on the side of car seats generally cannot be very large, resulting in relatively small internal space. Conventional cup holders cannot be installed, failing to meet customers' needs for cup holders on the small armrests.

[0003] This patent, published in CN217320160U, discloses a side armrest cup holder mechanism, including a cup holder with a placement groove. The cup holder has two rotating shafts and two pins, each connected to a clamping arm. An extension rod is located at the end of each clamping arm away from the placement groove, and the extension rod is connected to the pin via an elastic reset structure. By providing an elastic reset structure between the extension rod and the pin, when a cup is placed in the placement groove, the two clamping arms are pushed outwards by downward pressure, causing the elastic reset structure to deform and compress. After the cup is in place, the elastic reset structure opens and resets, simultaneously pushing the extension rod outwards, allowing the two clamping arms to clamp the cup tightly, thus accommodating cups of different sizes. However, this patent suffers from a complex structure, inconvenient use, and the two clamping arms cannot be brought together for storage.

[0004] The patent publication number CN108819814A discloses a cup holder, a cup holder assembly and an automobile. Each clamp (claw) in this patent is clamped by a reset member (i.e., a reset spring), and the claw cannot be pre-deployed.

[0005] The patent publication number CN104309511A discloses a new type of car cup holder. Each extrusion plate (i.e., the claw) is clamped by a spring, and the claw cannot be pre-deployed.

[0006] Currently, there are cup holder armrests on the market that can achieve pre-deployment of the claws, but their installation structure is complicated, and the pre-deployment of the claws requires a separate power mechanism, resulting in high overall production costs. Utility Model Content

[0007] In view of the problems existing in the prior art, the present invention aims to provide an armrest assembly with a cup holder, so as to solve the problems of complex installation structure of existing cup holder armrests and the need for a separate power mechanism to pre-deploy the cup holder claws.

[0008] To achieve the above objectives, this utility model proposes an armrest assembly with a cup holder, comprising an armrest shell, an armrest frame, and a cup holder assembly. The armrest shell includes an upper armrest cover and a lower armrest cover. The cup holder assembly includes a cup holder body, a cup holder gripper, and a cup holder storage shell. The cup holder storage shell and the armrest frame are both fixed inside the armrest shell. The cup holder body is slidably disposed within the cup holder storage shell. Both the front end of the cup holder storage shell and the front end of the lower armrest cover have openings for the cup holder body to slide out. A locking mechanism and a pop-out mechanism are also provided between the cup holder body and the cup holder storage shell. The locking mechanism is used to lock the cup holder body within the cup holder storage shell to achieve storage of the cup holder body. When the locking mechanism is unlocked, the pop-out mechanism can drive the cup holder body to slide forward. The cup holder gripper is fixed to the cup holder body. When the cup holder body slides forward, it can cause the cup holder gripper to open from a retracted state to a pre-expanded state.

[0009] In the above solution: the locking mechanism includes a button cover, a button, a linkage bracket, and a locking bracket. The locking bracket slides up and down and is confined within the cup holder body. A return spring is provided between the top of the locking bracket and the cup holder storage shell. A locking tongue is provided at the bottom of the locking bracket. A locking hole is provided on the cup holder storage shell at the position corresponding to the locking tongue. The locking tongue is inserted downward into the locking hole. The front end of the cup holder body protrudes from the cup holder storage shell. The button cover is fixed to the front end face of the cup holder body and covers the opening of the armrest cover. The button is embedded in the button... On the cover plate, the linkage bracket is in the shape of an "A", with its upper end hinged to the button cover plate and its oblique front end in contact with the rear end of the button. Its oblique rear end has a U-shaped opening along its length. The upper part of the locking bracket has a hollow part for the oblique rear end of the linkage bracket to extend into and rotate. A horizontally extending pin is connected between the two side walls of the hollow part. The pin is movably inserted into the U-shaped opening. Pressing the button can drive the linkage bracket to rotate clockwise, thereby driving the pin and the locking bracket to move upward, so that the lock tongue disengages from the lock hole, realizing the unlocking of the locking mechanism.

[0010] The rear end of the button is fitted with a spring steel wire, and the two ends of the spring steel wire are fixed to the button cover plate. After the button is pressed, the spring steel wire has the elastic force to drive the button to reset.

[0011] In the above solution: the pop-out mechanism includes a coil spring, which is in a forward and backward stretched state. The front end of the coil spring is fixed to the cup holder storage shell, and the rear end of the coil spring is fixed to the cup holder body. The coil spring stores the elastic force that drives the cup holder body to slide forward.

[0012] In the above solution: two uprights are arranged side by side on the top surface of the cup holder body; the cup holder grippers include two grippers arranged opposite each other, with the rear ends of the two grippers respectively hinged to the corresponding uprights; and each of the rear ends of the two grippers has an inwardly arranged arc-shaped rack, which meshes together, with the corresponding uprights as the center of the two arc-shaped racks. The front ends of the two grippers together form a cup holder groove; the cup holder body below the groove is designed to accommodate a water cup; and the two grippers also have... Equipped with a return spring, the cup holder gripper also includes two symmetrically arranged transmission brackets. The middle of each transmission bracket is hinged to the corresponding side column. The front end of each transmission bracket abuts against the rear end of the corresponding side gripper. The ends of each transmission bracket are provided with upward guide posts. The cup holder storage shell is provided with two symmetrical guide grooves corresponding to the two guide posts. The two guide grooves extend back and forth, and the front ends of the two guide grooves are inwardly close in a figure-eight shape. The two guide posts are movably inserted into the rear end of the corresponding side guide groove.

[0013] When the cup holder body slides forward relative to the cup holder storage shell, it can drive the two guide posts to slide along the corresponding side guide grooves. When the two guide posts slide to the front end of the corresponding side guide grooves, the two guide posts can drive the ends of the two transmission brackets to move closer to each other, thereby driving the front ends of the two transmission brackets to move away from each other, and then driving the two grippers to open outward. When the cup holder body slides forward to the use position, the two grippers are just open outward to the pre-expanded state.

[0014] The cup holder grippers move in tandem with the main body of the cup holder, enabling automatic pre-expansion or automatic retraction at the designed position. No additional power mechanism is required. The overall structure is simple and ingeniously designed, effectively reducing the manufacturing cost of the cup holder assembly.

[0015] The design incorporates a linkage function between the two claws, which engage via an arc-shaped rack. When a cup is placed, the cup compresses one claw, causing it to unfold, while the other claw unfolds simultaneously. This eliminates the need to place the cup upright and compress both claws at the same time, resulting in improved human-computer interaction.

[0016] In the above scheme: the rear end of the top surface of the gripper is recessed to form a sinking groove, and an abutment wall is provided on the sinking groove. The front end and middle part of the transmission bracket are arranged in the sinking groove, and the front end of the transmission bracket abuts against the corresponding side abutment wall. The cup holder gripper also includes a cover plate, which is placed on top of the two transmission brackets and fixed to the cup holder body. The structure is compact and the arrangement is reasonable. The cover plate can protect the transmission bracket and the arc gear and cover dust.

[0017] In the above solution: the cup holder housing has sliding grooves extending forward and backward on both sides, and the cup holder body has protrusions on both sides that extend into the corresponding sliding grooves. When the protrusions slide to the front end of the sliding groove, the cup holder body is in the use position, and the protrusions cooperate with the sliding grooves to limit the forward travel of the cup holder body. When the locking tongue of the locking bracket is inserted into the lock hole, the cup holder body is in the storage position.

[0018] In the above solution: a felt is fixed on the front end surface of the slide groove. The felt serves as an isolation layer to prevent the protrusion from sliding to the front end of the slide groove and causing collision noise.

[0019] In the above solution: the cup holder storage shell is fixed to the lower armrest cover by screws and a snap-fit ​​structure, and is located inside the front end of the lower armrest cover. The front end of the armrest frame is fixed to the upper part of the cup holder storage shell by screws. The rear end of the armrest frame extends downward and is fixed to the lower armrest cover by screws. An auxiliary connecting bracket is fixed to the upper part of the rear end of the armrest frame by screws. Both the auxiliary connecting bracket and the front end of the armrest frame are provided with locking holes. The upper armrest cover is provided with buckles corresponding to each locking hole inside. The buckles are engaged in the corresponding locking holes, thereby realizing the snap-fit ​​connection between the upper armrest cover and the lower armrest cover.

[0020] Due to considerations of product molding and demolding, the interior rear end of the armrest cover is designed to be relatively open, making it impossible to install the snap-fit ​​points of the armrest cover. Therefore, an auxiliary connecting bracket is required as an intermediate connecting part to hide all the snap-fit ​​structures and screws inside the armrest shell, thus avoiding affecting the appearance consistency and aesthetics of the armrest assembly.

[0021] In the above scheme: a damping gear is fixed at the bottom of the cup holder body, and a rack extending forward and backward is arranged at the bottom of the inner cavity of the cup holder storage shell. The damping gear meshes with the rack, that is, the damping gear cooperates with the rack, and plays a buffering role when the cup holder body pops out.

[0022] In the above solution: the cup holder assembly further includes a strip of sheet metal extending front and rear, which is fixed to the bottom of the cup holder body, and the bottom of the cup holder body has a receiving groove for accommodating the strip of sheet metal. The cup holder body is usually made of plastic, and because it has a cup groove for accommodating a water cup, its structural strength is relatively weak. By adding a strip of sheet metal to its bottom, the structural strength of the cup holder body is effectively enhanced.

[0023] The beneficial effects of this utility model are:

[0024] 1. A pre-deployment function for the cup holder has been added, making it more convenient to use. There's no need to manually pry open the cup holder to place it, providing a better user experience compared to the previous design. 2. The cup holder grippers move in tandem with the main body of the cup holder, automatically opening or retracting at the designated positions without requiring an additional power mechanism. This ingenious design also simplifies the structure of pop-up cup holders. 3. The armrest assembly has a simple installation structure, mainly composed of the armrest shell, armrest frame, and cup holder assembly. With fewer parts, it is easy to assemble and highly practical.

[0035] like Figure 1 As shown in Figure 9, an armrest assembly with a cup holder mainly consists of an armrest shell, an armrest frame 1, and a cup holder assembly. The armrest shell includes an upper armrest cover 2 and a lower armrest cover 3, and the cup holder assembly includes a cup holder body 4, a cup holder claw 6, and a cup holder storage shell 5.

[0036] Both the cup holder housing 5 and the armrest frame 1 are fixed inside the armrest housing. The cup holder body 4 is slidably disposed within the cup holder housing 5, and both the front end of the cup holder housing 5 and the front end of the armrest cover 3 have openings for the cup holder body 4 to slide out. A locking mechanism and a pop-out mechanism are also provided between the cup holder body 4 and the cup holder housing 5. The locking mechanism is used to lock the cup holder body 4 inside the cup holder housing 5 to achieve storage of the cup holder body 4.

[0037] When the locking mechanism is unlocked, the pop-out mechanism can drive the cup holder body 4 to slide forward. The cup holder claw 6 is fixed on the cup holder body 4. When the cup holder body 4 slides forward, it can drive the cup holder claw 6 to open from the retracted state to the pre-expanded state.

[0038] Preferably, the locking mechanism includes a button cover 7, a button 8, a linkage bracket 9, and a locking bracket 10. The locking bracket 10 slides up and down and is confined within the cup holder body 4. Specifically, the upper and lower sides of the locking bracket 10 are provided with arc-shaped protrusions 105, and the locking bracket 10 slides up and down within the cup holder body 4 through the arc-shaped protrusions 105. A return spring 101 is provided between the top of the locking bracket 10 and the cup holder storage shell 5, and a locking tongue 102 is provided at the bottom of the locking bracket 10. A locking hole 51 is provided on the cup holder storage shell 5 at the position corresponding to the locking tongue 102, and the locking tongue 102 is inserted downward into the locking hole 51.

[0039] The front end of the cup holder body 4 exposes the cup holder storage shell 5. The button cover 7 is fixed to the front end surface of the cup holder body 4 and covers the opening of the armrest cover 3. The button 8 is embedded in the button cover 7. The rear end of the button 8 is secured with a spring steel wire 81. Both ends of the spring steel wire 81 are limited and fixed to the button cover 7. After pressing the button 8, the spring steel wire 81 has the elastic force to drive the button 8 to reset.

[0040] The linkage bracket 9 is in the shape of an "A", with its upper end hinged to the button cover plate 7, its oblique front end contacting the rear end of the button 8, and its oblique rear end having a U-shaped opening along its length. The upper part of the locking bracket 10 has a hollow part 103 for the oblique rear end of the linkage bracket 9 to extend into and rotate. A horizontally extending pin 104 is connected between the two side walls of the hollow part 103, and the pin 104 is movably inserted into the U-shaped opening.

[0041] Pressing button 8 causes the linkage bracket 9 to rotate clockwise, which in turn causes the pin 104 and locking bracket 10 to move upward, causing the lock tongue 102 to disengage from the lock hole 51, thus unlocking the locking mechanism.

[0042] Preferably, the pop-out mechanism includes a coil spring 11, which is in a forward and backward stretched state. The front end of the coil spring 11 is fixed to the cup holder storage shell 5, and the rear end of the coil spring 11 is fixed to the cup holder body 4. The coil spring 11 stores the elastic force that drives the cup holder body 4 to slide forward.

[0043] Ideally, two uprights 41 are arranged side-by-side on the top surface of the cup holder body 4. The cup holder grippers 6 include two grippers 61 arranged opposite each other on the left and right sides. The rear ends of the two grippers 61 are respectively hinged to the corresponding uprights 41, and the rear ends of the two grippers 61 are provided with arc-shaped racks 62 inward. The two arc-shaped racks 62 mesh together, and the two arc-shaped racks 62 are respectively centered on the corresponding uprights 41. The front ends of the two grippers 61 form a cup holder groove. The cup holder body 4 below the groove is designed to be recessed to accommodate the cup. The two grippers 61 are also equipped with return springs.

[0044] The cup holder gripper 6 also includes two symmetrically arranged transmission brackets 63. The middle part of each transmission bracket 63 is hinged to the corresponding side column 41. The front end of each transmission bracket 63 abuts against the rear end of the corresponding side gripper 61. The ends of each transmission bracket 63 are provided with upward guide posts 64. The cup holder storage shell 5 is provided with two symmetrical guide grooves 52 corresponding to the two guide posts 64. The two guide grooves 52 extend back and forth, and the front ends of the two guide grooves 52 are inwardly close in a figure-eight shape. The two guide posts 64 are movably inserted into the rear end of the corresponding side guide groove 52.

[0045] When the cup holder body 4 slides forward relative to the cup holder storage shell 5, it can drive the two guide posts 64 to slide along the corresponding side guide grooves 52. When the two guide posts 64 slide to the front end of the corresponding side guide grooves 52, the two guide posts 64 can drive the ends of the two transmission brackets 63 to move closer to each other, thereby driving the front ends of the two transmission brackets 63 to move away from each other, and then driving the two grippers 61 to open outward. When the cup holder body 4 slides forward to the use position, the two grippers 61 just open outward to the pre-expanded state.

[0046] The cup holder gripper 6 moves in tandem with the cup holder body 4, enabling automatic pre-expansion or automatic retraction at the designed position. No additional power mechanism is required. The overall structure is simple and ingeniously designed, effectively reducing the manufacturing cost of the cup holder assembly.

[0047] This structure adds a claw linkage function. The two claws 61 are engaged by the arc-shaped rack 62. When a cup is placed, the cup squeezes one claw 61 to unfold, and the other claw 61 will also unfold at the same time. It is not necessary to place the cup upright and squeeze both claws 61 at the same time. This design provides a better human-computer interaction.

[0048] Ideally, the rear end of the gripper 61 is recessed to form a groove 65, and an abutment wall 66 is provided on the groove 65. The front end and middle part of the transmission bracket 63 are arranged in the groove 65, and the front end of the transmission bracket 63 abuts against the corresponding abutment wall 66. The cup holder gripper 6 also includes a cover plate 67, which is placed on top of the two transmission brackets 63 and fixed to the cup holder body 4. The structure is compact and the arrangement is reasonable. The cover plate 67 can protect the transmission brackets 63 and the arc gear 62 and keep them dust-proof.

[0049] Ideally, the cup holder housing 5 has sliding grooves 53 extending forward and backward on both sides, and the cup holder body 4 has protrusions on both sides that extend into the corresponding sliding grooves 53. When the protrusions slide to the front end of the sliding groove 53, the cup holder body 4 is in the use position, and the protrusions cooperate with the sliding groove 53 to limit the forward travel of the cup holder body 4. When the locking tongue 102 of the locking bracket 10 is inserted into the lock hole 51, the cup holder body 4 is in the storage position.

[0050] Ideally, a felt 54 is fixed on the front end face of the slide groove 53. The felt 54 serves as an isolation to prevent the protrusion from sliding to the front end of the slide groove 53 and causing collision noise.

[0051] Ideally, the cup holder housing 5 is fixed to the lower armrest cover 3 by screws and a snap-fit ​​structure 16, and is positioned inside the front end of the lower armrest cover 3. The front end of the armrest frame 1 is fixed to the upper part of the cup holder housing 5 by screws, and the rear end of the armrest frame 1 extends downward and is fixed to the lower armrest cover 3 by screws. An auxiliary connecting bracket 12 is fixed to the upper part of the rear end of the armrest frame 1 by screws. Both the auxiliary connecting bracket 12 and the front end of the armrest frame 1 are provided with locking holes. The interior of the upper armrest cover 2 is provided with buckles corresponding to each locking hole. The buckles engage with the corresponding locking holes, thereby achieving the snap-fit ​​connection between the upper armrest cover 2 and the lower armrest cover 3.

[0052] Due to considerations of product molding and demolding, the interior rear end of the lower cover 3 of the armrest is designed to be relatively open, and the snap-fit ​​points of the upper cover 2 of the armrest cannot be arranged on it. Therefore, an auxiliary connecting bracket 12 is required as an intermediate connecting part to hide all the snap-fit ​​structures and screws inside the armrest shell, so as to avoid affecting the appearance consistency and aesthetics of the armrest assembly.

[0053] Ideally, a damping gear 13 is fixed at the bottom of the cup holder body 4, and a rack 14 extending forward and backward is arranged at the bottom of the inner cavity of the cup holder housing 5. The damping gear 13 meshes with the rack 14, that is, the damping gear 13 and the rack 14 cooperate to play a buffering role when the cup holder body 4 pops out.

[0054] Preferably, the cup holder assembly also includes a strip sheet metal 15 extending front and rear, the strip sheet metal 15 being fixed to the bottom of the cup holder body 4, and the bottom of the cup holder body 4 having a receiving groove for accommodating the strip sheet metal 15. The cup holder body 4 is typically made of plastic, and because it has a cup groove for accommodating a cup, its structural strength is relatively weak. By adding the strip sheet metal 15 to its bottom, the structural strength of the cup holder body 4 is effectively enhanced.

[0055] Ideally, a concealing sheet metal 17 is fixedly installed at the front interior of the armrest cover 2. The concealing sheet metal 17 completely covers the front interior of the armrest cover 2, and a supporting rib is provided between the top surface of the concealing sheet metal 17 and the armrest cover 2. The supporting rib is integrally formed with the concealing sheet metal 17. The concealing sheet metal 17 serves both to conceal the internal structure of the armrest when the cup holder assembly is opened, ensuring that the internal structure of the armrest is not exposed when viewed from an awkward angle, and to provide support, thereby enhancing the structural strength of the front end of the armrest cover 2.
