Description

Technical Field

[0001] This utility model relates to the field of vehicle cup holder technology, specifically to a cup holder with a smooth cover. Background Technology

[0002] Car cup holders are common automotive devices, designed to keep drinks secure and prevent spills that could soil or wet interior components or the user's clothing. Their importance in automotive design is increasingly evident; they are typically designed to be concealed within the dashboard or integrated with the center console, maximizing space utilization while ensuring ease of use. Common car cup holders often feature flip-top or roll-up covers. However, flip-top cup holders can take up valuable interior space when flipped, while roll-up cup holders are structurally more complex and less stable. Therefore, this invention proposes a cup holder with a smooth-mounted cover to address these technical problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a cup holder with a smooth cover. The cover is longitudinally slidably mounted on a horizontal base plate via slide rail assemblies located on the left and right sides. A gear located on the horizontal base plate meshes with a rack inside a longitudinal guide groove on the lower end face of the cover. A labyrinth limiting mechanism is provided between the lower side of the cover and the upper side of the horizontal base plate. The upper port of the cup holder is opened or closed by smoothly pushing the cover on the upper side of the horizontal base plate. Its structure is simple and the mechanism has good stability. Compared with flip-top or roll-up cup holders, it is more suitable for in-vehicle installation in places such as the dashboard or center console, without occupying the activity space inside the vehicle.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a cup holder with a smooth cover, including a horizontal base plate, a cup holder, and a cover plate. The upper end of the cup holder is inserted and fixedly installed inside the cup holder mounting groove at the front end of the horizontal base plate. A gear assembly is fixedly installed at the rear end of the upper side of the horizontal base plate. The lower side of the cover plate has a longitudinal guide groove extending in the front-back direction, and a rack is provided on the left or right vertical inner wall surface of the longitudinal guide groove. The cover plate is longitudinally slidably installed above the horizontal base plate by slide rail assemblies located at the left and right side edges. The gear located at the upper end of the gear assembly is movably embedded in the longitudinal guide groove on the lower end surface of the cover plate and meshes with the rack. A labyrinth limiting mechanism is provided between the lower side of the cover plate and the upper side of the horizontal base plate. The labyrinth limiting mechanism has two states: locked and unlocked. In the unlocked state, the cover plate covers the upper end of the cup holder, and the cover plate and the horizontal base plate can slide relative to each other in the front-back direction. In the locked state, the cover plate is located at the rear end of the horizontal base plate, and the cover plate and the horizontal base plate are locked together.

[0005] This utility model discloses a cup holder with a smooth cover. The cover is longitudinally slidably mounted on a horizontal base plate via slide rail assemblies located on the left and right sides. A gear located on the horizontal base plate meshes with a rack inside a longitudinal guide groove on the lower end face of the cover. A labyrinth limiting mechanism is provided between the lower side of the cover and the upper side of the horizontal base plate. The upper port of the cup holder is opened or closed by smoothly pushing the cover on the upper side of the horizontal base plate. Its structure is simple and the mechanism has good stability. Compared with flip-top or roll-up cup holders, it is more suitable for vehicle installation in the dashboard or center console, etc., without occupying the activity space in the vehicle. It has high feasibility for manufacturing and implementation and strong practicality.

[0006] A preferred technical solution is that the rear end of the horizontal base plate has a rectangular slot, and the front ends of the vertical inner walls on both sides of the rectangular slot are provided with upward-opening notches. The system also includes a coil spring, the front end of which is wound into the rectangular slot via a coil assembly, and the rear end is fixed to the rear edge of the cover plate. Both ends of the coil assembly are embedded in the notches on the vertical inner walls on both sides of the rectangular slot. By providing a coil spring between the horizontal base plate and the cover plate, a certain elastic tension is always maintained between them. When the cover plate covers the upper port of the cup holder (the labyrinth limit mechanism is in the unlocked state), this effectively prevents the cover plate from sliding freely and generating abnormal noise during operation. Furthermore, during the process of pushing the cover plate from back to front to cover the upper port of the cup holder, the coil spring always exerts a forward pulling force on the cover plate to ensure that the cover plate can completely cover the upper port of the cup holder.

[0007] A further preferred technical solution includes a rectangular slot located in the middle of a horizontal substrate, a horizontal ear plate protruding from the middle of the rear end face of the cover plate, a stepped groove at the rear end edge of the horizontal ear plate, and a hook groove bent at the rear end of the coil spring that hooks into the stepped groove. The simple method of fixing the rear end of the coil spring to the rear end of the cover plate ensures the smooth fabrication and implementation of the cup holder of this invention.

[0008] A further preferred technical solution is that the rear end of the upper side of the horizontal substrate has a gear mounting groove and a locking component mounting groove that penetrate the plate body, and the gear mounting groove and the locking component mounting groove are located on the left and right sides of the rectangular slot hole respectively. The gear assembly also includes a frustum base, and the gear is rotatably mounted on the middle of the upper end face of the frustum base. The frustum base is embedded and fixed inside the gear mounting groove, and the gear protrudes from the upper side of the horizontal substrate.

[0009] The maze limiting mechanism includes a maze groove and a locking member. The locking member mounting groove is located at the rear end edge of the upper side of the horizontal base plate. The locking member is rotatably mounted at the bottom of the locking member mounting groove. The upper end of the locking member has a locking pin extending upward. The maze groove is opened at the rear end of the lower side of the cover plate and opens backward. The front edge of the maze groove is provided with a rearward-opening groove 1, a guide slope 1, and a groove 2 in sequence. The lower side of the cover plate is also provided with a locking protrusion located at the front end of the maze groove. The rear edge of the locking protrusion has a guide slope 2, and the front edge has a locking groove opening forward. The locking groove corresponds to the guide slope 1.

[0010] When the maze limiting mechanism is in the locked state, the locking pin engages with the locking groove of the locking protrusion to lock the cover plate and the horizontal base plate together. The gear assembly structure is ingeniously and reasonably designed, and the fixing and installation method at the rear end of the side of the horizontal base plate is simple. At the same time, the maze limiting mechanism structure is ingeniously and reasonably designed to ensure that the cover plate and the horizontal base plate can be locked together in the locked state.

[0011] A further preferred technical solution includes two lugs fixed to the lower end of the outer peripheral side of the frustum base, corresponding to the two ends of the same diameter. A "7"-shaped locking block extending upward is fixed on the lug. The lower end face of the horizontal substrate has two countersunk grooves corresponding to the two ends of the same diameter at the lower port of the gear mounting groove and opening downward. The inner peripheral wall of the gear mounting groove has two notches located at the two ends of the same diameter, and the two notches and the two countersunk grooves are connected to each other. The frustum base is embedded in the gear mounting groove, the two lugs are embedded in the corresponding countersunk grooves, and the "7"-shaped locking block passes out from the corresponding notch and is locked onto the upper side of the horizontal substrate.

[0012] The bottom of the locking component mounting groove is provided with a mounting hole and two corresponding slots located at both ends of the mounting hole with the same diameter. The two slots are connected to the mounting hole. The locking component includes a frustum base two. The frustum base two has a lug on its outer peripheral side and a shaft at its lower end. The locking pin is vertically located on the upper side of the lug. The lower end of the outer peripheral side of the shaft has two protrusions located at both ends of the same diameter on the cross-section of the shaft. The shaft is rotatably connected to the inside of the mounting hole. The two protrusions are located on the lower side of the horizontal base plate, and the frustum base two is located on the upper side of the bottom of the horizontal base plate. The bottom of the locking component mounting groove is also provided with an arc-shaped locking block located on the rotation path of the lug so that the two protrusions are offset from the two slots. The gear assembly and gear mounting groove are ingeniously and rationally designed to effectively prevent the circumferential rotation of the frustum base when the gear and rack mesh, ensuring the firmness of the gear assembly on the side of the horizontal base plate. The locking element and locking element mounting groove are well compatible, and the arc-shaped locking block can limit the travel path position of the lugs, ensuring that the two lugs and the two slots are always misaligned, effectively preventing the locking element from coming out of the locking element mounting groove, and ensuring the safety of the cup holder during use.

[0013] A further preferred technical solution is that the bottom of the locking component mounting groove is also provided with an arc-shaped slot located on the outer periphery of the mounting hole. One end of the arc-shaped locking block is fixed to the inner wall of one end of the arc-shaped slot, and the other end protrudes from the upper side of the bottom of the locking component mounting groove. This gives the arc-shaped locking block a certain degree of pressing elasticity, thereby helping to improve the convenience of installing the locking component inside the locking component mounting groove.

[0014] A further preferred technical solution includes two longitudinal guide grooves at the rear end of the upper side of the horizontal substrate. The gear mounting groove, rectangular slot, and locking component mounting groove are all located between the two longitudinal guide grooves. Two guide blocks protrude from the rear end of the lower side of the cover plate, and the two guide blocks are installed one-to-one inside the two longitudinal guide grooves on the upper side of the horizontal substrate. Buffer blocks are fixed to the rear ends of the two longitudinal guide grooves. The left and right sides of the cover plate also slide with the longitudinal guide grooves on the upper side of the horizontal substrate through the guide blocks, further ensuring the stability of the cover plate when sliding open or closing the upper port of the cup holder.

[0015] A further preferred technical solution is that the gear is a damping gear. A damping gear has a certain damping effect, which helps to improve the comfort and smoothness of the lid sliding open or close the upper port of the cup holder, and also has a certain effect in eliminating vibration and sliding noise.

[0016] A further preferred technical solution includes two guide rails fixedly disposed on the left and right sides of the upper side of the horizontal substrate, each along its front-to-back length. The two guide rails have grooves facing the cover plate. Slide platforms along the front-to-back length are fixedly disposed on the left and right sides of the cover plate, respectively. The cover plate is slidably inserted into the grooves on the corresponding guide rails via the slide platforms located on the left and right sides. The guide rails and the slide platforms slidably inserted into them constitute a slide rail assembly. The slide rail assembly has a clever and reasonable structural design, ensuring the smooth fabrication and implementation of the cup holder of this invention.

[0017] A further preferred technical solution is that the cover plate is composed of a bottom plate on the lower side and a decorative plate on the upper side, with an abutment block clamped and fixed at their front ends. The front edge of the horizontal base plate has an upwardly extending eave. When the cover plate covers the upper end of the cup holder, the abutment block abuts against the eave. The cover plate structure is cleverly and reasonably designed, and when the maze limiting mechanism is in the unlocked state, the abutment block abuts against the eave, effectively preventing the cover plate from sliding forward excessively, thus improving the sealing and safety when the cover plate slides to close the cup holder.

[0018] The advantages and beneficial effects of this utility model are as follows:

[0019] 1. This utility model discloses a cup holder with a smooth cover plate. The cover plate is longitudinally slidably mounted on a horizontal base plate via slide rail assemblies located on the left and right sides. A gear located on the horizontal base plate meshes with a rack inside a longitudinal guide groove on the lower end face of the cover plate. A labyrinth limiting mechanism is provided between the lower side of the cover plate and the upper side of the horizontal base plate. The upper port of the cup holder is opened or closed by smoothly pushing the cover plate on the upper side of the horizontal base plate. Its structure is simple and the mechanism has good stability. Compared with flip-top or roll-up cup holders, it is more suitable for vehicle installation in the dashboard or center console, etc., without occupying the activity space in the vehicle. It has high feasibility for manufacturing and implementation and strong practicality.

[0020] 2. By providing a coil spring between the horizontal base plate and the cover plate, a certain elastic tension is always present between the cover plate and the horizontal base plate. When the cover plate covers the upper port of the cup holder (the labyrinth limit mechanism is in the unlocked state), it effectively prevents the cover plate from sliding freely and generating abnormal noise during driving. Furthermore, during the process of pushing the cover plate from back to front to cover the upper port of the cup holder, the coil spring always exerts a forward pulling force on the cover plate to ensure that the cover plate can completely cover the upper port of the cup holder.

[0021] 3. The gear assembly structure is ingeniously and reasonably designed, and the fixed installation method on the side rear end of the horizontal base plate is simple. The maze limiting mechanism structure is ingeniously and reasonably designed to ensure that the cover plate and the horizontal base plate can be locked together when locked.

[0022] 4. The gear assembly and gear mounting groove are ingeniously and reasonably designed to effectively prevent the circumferential rotation of the frustum base when the gear and rack mesh, ensuring the firmness of the gear assembly on the side of the horizontal base plate; the locking element and locking element mounting groove are well compatible, and the arc-shaped block can limit the travel path position of the lugs, ensuring that the two lugs and the two grooves are always misaligned, effectively preventing the locking element from coming out of the locking element mounting groove, and ensuring the safety of the cup holder during use.

[0023] 5. The left and right sides of the cover plate are also slidably engaged with the longitudinal guide groove on the upper side of the horizontal base plate through guide blocks, which further ensures the stability of the cover plate when sliding open or closing the upper port of the cup holder.

[0024] 6. The gear mentioned is a damping gear. The damping gear has a certain damping effect, which helps to improve the comfort and smoothness of the lid sliding open or close the upper port of the cup holder, and also has a certain effect of eliminating vibration and sliding noise.

[0025] 7. The cover plate has a clever and reasonable structural design. When the labyrinth limit mechanism is in the unlocked and tight state, the abutment block abuts against the eaves, which effectively prevents the cover plate from sliding forward excessively and improves the sealing and safety of the cup holder when the cover plate slides to close.

[0057] The working principle of this utility model is as follows: A cup holder with a smooth cover.

[0058] The initial state is when the cover plate 3 covers the upper port of the cup holder 2. At this time, the maze limiting mechanism is in the unlocked state (see appendix). Figure 1 Push the cover plate 3 backward, and the locking pin 6-3 on the locking member 6 begins to enter the labyrinth groove 3-1d and begins to contact one end of the guide slope 3-1h-1. At this time, the position of the locking pin 6-3 is recorded as position ① (see Appendix). Figure 13 Continue pushing the cover plate 3 backward, the locking pin 6-3 enters the labyrinth groove 3-1d and contacts the other end of the guide slope 3-1h-1. At this time, the position of the locking pin 6-3 is recorded as position ②. Subsequently, the cover plate 3 is pushed backward, and the locking pin 6-3 contacts the front end of the left edge of the locking protrusion 3-1h in sequence, recorded as position ③. The locking pin 6-3 enters the groove 3-1d-1, recorded as position ④ (this position is the limit position of the cover plate 3's backward movement). At this time, the cover plate 3 is released, and the cover plate 3 rebounds a distance to the front end under the elastic action of the coil spring 5. At this time, the locking pin 6-3 enters the locking groove 3-1h-2, recorded as position ⑤. At this time, the labyrinth locking mechanism changes to the locked state (see appendix). Figure 14 When it is necessary to re-cover the upper port of the cup holder 2 with the cover plate 3, push the cover plate 3 further back a certain distance. At this time, the locking pin 6-3 enters the interior of the groove 3-1d-3 along the guide slope 3-1d-2, which is marked as position ⑥. Then, the cover plate 3 continues to move forward under the elastic driving force of the coil spring 5. When the locking pin 6-3 moves to the rear end of the right edge of the locking protrusion 3-1h, it is marked as position ⑦. When the locking pin 6-3 moves to the exit near the labyrinth groove 3-1d, it is marked as position ⑧ (see appendix). Figure 15 Finally, the cover plate 3 moves to the upper port of the cup holder 2, and the abutment block 3-3 on the cover plate 3 abuts against the eaves 1-7 at the front end of the horizontal base plate 1. At this time, the maze limiting mechanism returns to the unlocked state (see appendix). Figure 1 ).

[0059] This utility model discloses a cup holder with a smooth cover.
