Description

Technical Field

[0001] This application relates to the field of car cup holders, and more particularly to a liftable cup holder. Background Technology

[0002] To facilitate the placement of water cups, coffee cups, or beverage bottles and reduce the probability of liquids spilling when the vehicle is bumpy, cup holders are often installed in the car.

[0003] Chinese utility model patent CN119283756A discloses a liftable cup holder, including a cup holder assembly. The cup holder assembly includes a left cup holder and a right cup holder. A cup holder base bracket is slidably connected between the left and right cup holders. A cup holder base is fixed to the upper end of the cup holder base bracket. A cup holder compression spring is connected between the lower end of the cup holder base bracket and the lower end of the left and right cup holders. A lock head is fixed to the lower end of the cup holder base bracket. A locking plate is slidably connected between the lower parts of the left and right cup holders. A locking plate spring is connected between the right part of the locking plate and the bottom of the right cup holder. An unlocking button assembly is installed on the left side of the left cup holder, and the lower part of the unlocking button assembly is connected to the locking plate. Place the beverage on the cup holder base and press down the cup holder spring. The cup holder base, along with the cup holder base bracket and the lock head, will move down together. Then, the lock head will engage with the locking groove of the locking plate, thus locking the cup holder base. The cup holder can then surround the beverage. After finishing the beverage, press the unlock button. This will push the locking plate through the transmission rod, causing the locking groove and the lock head to misalign. Then, the cup holder spring will reset, pushing the cup holder base back up to its original position.

[0004] Regarding the aforementioned technologies, the inventors believe that the unlocking button of the adjustable cup holder is installed on the left side of the cup holder. During the process of the cup holder base moving up and resetting, the user is easily pinched by the cup holder base and the cup holder, posing a safety hazard. Utility Model Content

[0005] In order to reduce the probability of users getting their hands pinched while using the height-adjustable cup holder, this application provides a height-adjustable cup holder.

[0006] The liftable cup holder provided in this application adopts the following technical solution:

[0007] A height-adjustable cup holder includes a cup holder body, a sliding seat assembly slidably mounted on the cup holder body, a locking component slidably mounted on the cup holder body and locked in engagement with the sliding seat assembly, and an unlocking mechanism cooperating with the locking component. The cup holder body has an arrangement cavity for the sliding seat assembly to slide. The sliding seat assembly includes a sliding seat slidably mounted on the arrangement cavity, a locking part disposed at the bottom of the sliding seat, and a return spring that drives the sliding seat to always have a tendency to move away from the bottom of the arrangement cavity. The locking part has a first abutment surface, and the locking component has an abutment groove on the side facing away from the sliding seat for abutting in engagement with the first abutment surface. The unlocking mechanism includes an unlocking component and an unlocking plate hinged to the cup holder body and connecting the unlocking component and the locking component. The unlocking component is mounted on the top surface of the cup holder body.

[0008] By adopting the above technical solution, during the use of the height-adjustable cup holder, pressing down on the sliding seat causes the locking part at the bottom of the sliding seat to engage with the locking component. The first abutting surface of the locking part abuts against the abutting groove, thereby locking the sliding seat. This allows the cup to be placed on the top surface of the sliding seat and arranged in the arrangement groove of the cup holder body. When the sliding seat needs to be reset, simply press down on the unlocking component installed on the top surface of the cup holder body. Through the transmission of the unlocking plate, the locking component slides on the top of the cup holder body, causing misalignment between the first abutting surface of the locking part and the abutting groove. The sliding seat then returns to its initial position under the drive of the return spring. By placing the unlocking component on the top surface of the cup holder body, the probability of the user's hand being pinched during unlocking is reduced.

[0009] Optionally, the locking assembly includes a locking plate slidably mounted on the bottom of the cup holder body, a mounting post arranged on the cup holder body, and a locking spring sleeved on the mounting post. One end of the locking spring abuts against the locking plate and the other end abuts against the cup holder body. The locking plate includes a locking horizontal plate arranged perpendicular to the axial direction of the cup holder body and cooperating with the sliding seat assembly, and a locking side plate arranged perpendicular to the locking horizontal plate and abutting against the unlocking plate. The locking side plate has a mounting slot for the mounting post to pass through.

[0010] By adopting the above technical solution, the specific structure of the locking component is disclosed. When it is necessary to lock the sliding seat on the bottom surface of the arrangement cavity, the locking is achieved by the cooperation between the locking part at the bottom of the sliding seat and the locking cross plate of the locking plate. The cooperation between the mounting column and the locking spring sleeved on the mounting column achieves a stable cooperation between the locking plate and the adjusting seat assembly. While providing guidance for the sliding process of the locking plate, it can also realize the automatic reset of the locking plate.

[0011] Optionally, the locking plate has a limiting block protruding in the direction away from the cup holder body at the locking cross plate, and the bottom of the cup holder body has a limiting surface for abutting and cooperating with the limiting block.

[0012] By adopting the above technical solution, the sliding range of the locking plate can be limited by the cooperation between the upper limit block of the locking plate and the bottom limiting surface of the cup holder body, which effectively reduces the probability of the locking plate coming off the bottom of the cup holder body during the sliding process and ensures the normal implementation of the locking component function.

[0013] Optionally, the top of the cup holder body is provided with a mounting ring plate; the unlocking assembly includes an unlocking groove formed in the mounting ring plate, an unlocking button slidably mounted in the unlocking groove, an unlocking rod connected to the unlocking button and extending toward the unlocking plate, and an unlocking spring sleeved on the unlocking rod; one end of the unlocking spring abuts against the unlocking groove and the other end abuts against the unlocking button, the mounting ring plate has a sliding hole in the unlocking groove for the unlocking rod to pass through, the unlocking rod has a limiting protrusion for restricting the unlocking button from disengaging from the unlocking groove, and the unlocking plate has a second abutting surface that slopes downward toward the cup holder body on the side facing the unlocking rod.

[0014] By adopting the above technical solution, the specific structure of the unlocking component is disclosed. When it is necessary to unlock the locking structure between the sliding seat and the locking component, pressing down the unlocking button causes the unlocking button to drive the unlocking rod to abut against the top surface of the unlocking plate, driving the end of the unlocking plate near the unlocking rod to tilt away from the cup holder body, causing the end of the unlocking plate away from the unlocking rod to push the locking plate to slide in the opposite direction, causing the first abutting surface of the locking part to be misaligned with the abutting groove, thereby unlocking the sliding seat and the locking component. After stopping pressing down the unlocking button, the unlocking button can be reset under the drive of the unlocking spring.

[0015] Optionally, the unlocking lever has a third abutting surface that abuts against the second abutting surface. The third abutting surface is arranged downwards toward the cup holder body and the inclination angle of the third abutting surface is the same as that of the second abutting surface.

[0016] By adopting the above technical solution, the unlocking rod can stably and accurately push the unlocking plate through the cooperation between the third abutment surface of the unlocking rod and the second abutment surface of the unlocking plate, thereby effectively triggering the unlocking action, ensuring that the locking component is unlocked smoothly, and guaranteeing the normal use of the liftable cup holder.

[0017] Optionally, the outer side wall of the sliding seat is circumferentially provided with a first guide slider and a second guide slider, and the cup holder body is provided with a first guide groove for the first guide slider to slide and a second guide groove for the second guide slider to slide. The second guide groove passes through the inner and outer side walls of the cup holder body.

[0018] By adopting the above technical solution, the cooperation between the first guide slider and the second guide slider and the first guide groove and the second guide groove can provide guidance for the sliding process of the sliding seat and ensure the stable sliding of the sliding seat in the arrangement cavity.

[0019] Optionally, the sliding seat is equipped with a gear seat at the second guide slider, and the outer side wall of the cup holder body is provided with a lifting rack for cooperating with the gear seat.

[0020] By adopting the above technical solution, the gear seat on the second guide slider and the lifting rack on the cup holder body cooperate to provide damping, so that when the sliding seat returns to the opening of the cup holder body, it can rise slowly and smoothly, further improving the safety of the liftable cup holder during use.

[0021] Optionally, at least three sets of claw assemblies are evenly spaced around the outer side wall of the cup holder body. Each claw assembly has a first protrusion for clamping the cup and a second protrusion disposed at the bottom of the first protrusion. The bottom of the sliding seat has a guide groove that mates with the first protrusion.

[0022] By adopting the above technical solution, the claw assembly on the cup holder body helps to limit the cup placed in the arrangement cavity, further improving the stability of the cup placed in the liftable cup holder. The guide groove at the bottom of the sliding seat helps to drive the second protrusion to slide away from the cup holder body during the sliding seat's downward movement, thereby enabling the first protrusion to clamp the cup placed in the arrangement cavity and reducing the probability of the sliding seat being crushed and damaged by the second protrusion during the downward movement.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A height-adjustable cup holder, wherein during use, the sliding seat assembly is locked at the bottom of the arrangement cavity by pressing down until the locking part engages with the abutment groove of the locking assembly. When it is necessary to reset the sliding seat assembly, the sliding seat assembly and the locking assembly can be unlocked by pressing down the unlocking component on the top surface of the cup holder body, thereby achieving the upward reset of the sliding seat assembly. By setting the unlocking component on the top of the cup holder body, the probability of the user being pinched when resetting the sliding seat assembly is effectively reduced.

[0025] 2. Through the cooperation between the gear seat on the second guide slider and the lifting rack on the cup holder body, the structure between the gear seat and the lifting rack can play a damping role, so that when the sliding seat returns to the opening of the cup holder body, it can rise slowly and smoothly, further improving the safety of the liftable cup holder during use.

[0026] 3. The claw assembly on the cup holder body helps to improve the stability of the cup in the arrangement cavity. Attached Figure Description
