Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a pop-out cup holder unlocking mechanism. Background Technology

[0002] Cup holders are commonly found on the armrests of some car seats. For optimal space utilization, aesthetics, and comfort, these cup holders are often designed to be concealed, popping out when needed. Traditional pop-up cup holders for car seats typically consist of a mounting shell and a cup holder holder. The mounting shell contains a storage compartment for the holder, usually connected by a spring mechanism. When not in use, the holder retracts and locks into the storage compartment, with the spring stretched. To use the cup holder, the unlocking mechanism is activated, causing the spring to return to its original position and the holder to pop out of the storage compartment. However, current unlocking mechanisms suffer from poor stability and low structural strength. Because pop-up cup holders require frequent popping and retraction, their mechanical components are prone to wear. If the structure is weak, over time, parts of the unlocking mechanism may loosen, deform, or become damaged, preventing the cup holder from popping out or retracting properly. More importantly, existing unlocking mechanisms are prone to friction noise when mechanical parts are linked to unlock, and in severe cases, they may even lock up. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a pop-up cup holder unlocking mechanism to solve the problems of poor stability and easy generation of friction noise in the existing pop-up cup holder unlocking mechanism.

[0004] To achieve the above objectives, this utility model proposes a pop-out cup holder unlocking mechanism, including a cup holder body, a cup holder storage shell, and a pop-out mechanism. The cup holder body is slidably disposed within the cup holder storage shell, and the front end of the cup holder storage shell has an opening for the cup holder body to slide out. The pop-out mechanism has a spring force to drive the cup holder body to slide forward. It also includes a button cover, an unlock button, a linkage bracket, and a locking bracket. The locking bracket has arc-shaped protrusions on both sides of its upper and lower ends. The locking bracket is slidably disposed within the cup holder body via the arc-shaped protrusions and is circumferentially confined within the cup holder body. A return spring is provided between the top of the locking bracket and the cup holder storage shell, and a locking tongue is provided at the bottom of the locking bracket. The cup holder housing has a lock hole at the position corresponding to the locking tongue. The locking tongue is inserted downward into the lock hole to achieve sliding locking of the cup holder body. The locking bracket is also fixed with a left-right extending pin. The button cover is fixed to the front end face of the cup holder body. The unlocking button is embedded in the button cover. The linkage bracket is in the shape of "V". Its upper end is hinged to the button cover, its oblique front end contacts the rear end of the unlocking button, and its oblique rear end has a U-shaped opening along its length. The pin is movably inserted into the U-shaped opening. Pressing the unlocking button can drive the linkage bracket to rotate clockwise, thereby driving the pin and the locking bracket to move upward, so that the locking tongue disengages from the lock hole, thereby achieving sliding unlocking of the cup holder body.

[0005] In the above scheme: the upper part of the locking bracket is provided with a hollow part for the inclined rear end of the linkage bracket to extend into, and the pin is connected between the two side walls of the hollow part. The hollow part provides space for the inclined rear end of the linkage bracket to rotate.

[0006] In the above solution: a spring steel wire is installed at the rear end of the unlock button, and the two ends of the spring steel wire are fixed to the button cover plate. After the unlock button is pressed, the spring steel wire can drive the unlock button to reset.

[0007] In the above scheme: 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.

[0008] 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. Felt is fixed to the front end of the sliding groove. When the protrusions slide to the front end of the sliding groove, the cup holder body is in the use position. The protrusions and sliding grooves cooperate to limit the forward travel of the cup holder body, and the felt acts as an isolation layer to prevent collision noise when the protrusions slide to the front end of the sliding groove. When the locking tongue of the locking bracket is inserted into the lock hole, the cup holder body is in the storage position.

[0009] The beneficial effects of this utility model are:

[0010] 1. The locking bracket is slidably mounted within the cup holder body via an arc-shaped protrusion, effectively reducing the contact area between the locking bracket and the cup holder body, thereby reducing friction noise and mitigating the risk of the unlocking mechanism locking up to some extent. 2. The locking bracket is circumferentially confined within the cup holder body, the button cover is fixed to the cup holder body, the linkage bracket is hinged to the button cover, and the unlocking button is also embedded in the button cover. The overall structure is compact and strong, improving the stability of the unlocking mechanism and increasing its service life. 3. The unlocking button is located on the front surface of the cup holder for easier operation. Pressing the unlocking button rotates the linkage bracket clockwise, causing the pin and locking bracket to move upwards, disengaging the bolt from the lock hole and enabling the cup holder body to slide and unlock.

The cup holder body 1 is slidably disposed within the cup holder storage shell 2, and the front end of the cup holder storage shell 2 has an opening for the cup holder body 1 to slide out. The pop-up mechanism 3 has a spring force that drives the cup holder body 1 to slide forward.

[0020] On both sides of the upper end and both sides of the lower end of the locking bracket 7, arc-shaped protrusions 71 are provided. The locking bracket 7 is slidably arranged up and down in the cup holder main body 1 through the arc-shaped protrusions 71 and is circumferentially limited in the cup holder main body 1. A return spring 72 is arranged between the top end of the locking bracket 7 and the cup holder storage shell 2. A locking tongue 73 is provided at the bottom end of the locking bracket 7, and a locking hole 21 is provided at the position corresponding to the locking tongue 73 on the cup holder storage shell 2. The locking tongue 73 is inserted downward into the locking hole 21 to achieve the sliding locking of the cup holder main body 1.

Its upper end is hinged on the button cover plate 4, its oblique front end contacts the rear end of the unlocking button 5, and a U-shaped opening is provided along its length at its oblique rear end. The pin shaft 74 is movably inserted into the U-shaped opening.

[0022] Pressing the unlocking button 5 can drive the linkage bracket 6 to rotate clockwise, thereby driving the pin shaft 74 and the locking bracket 7 to move upward, making the locking tongue 73 disengage from the locking hole 21, and then realizing the sliding unlocking of the cup holder main body 1.

[0023] Preferably, a hollow part 75 for the oblique rear end of the linkage bracket 6 to extend into is provided in the upper part of the locking bracket 7. The pin shaft 74 is connected between the two side walls of the hollow part 75, and the hollow part 75 provides a space for the oblique rear end of the linkage bracket 6 to rotate.
