Description

Technical Field

[0001] This utility model belongs to the field of luggage cart structure technology, and specifically refers to a luggage cart. Background Technology

[0002] To make it easier for parents to take their children out, rolling suitcase strollers have appeared on the market. These strollers have detachable suitcases on the frame, where clothes and other items can be placed. When unfolded, the child can sit in the seat; when folded, the stroller can be used as a regular rolling suitcase.

[0003] For example, Chinese patent CN2024200948501 describes a detachable structure for a seatable trolley suitcase. It includes a frame and a suitcase. The frame comprises a main support and an auxiliary support hinged together, both equipped with wheels. The main support has a handle and a seat. A wheel axle is horizontally positioned at the lower end of the main support, with wheels on both sides of the axle. The suitcase has an open hinge seat at its lower end, and the wheel axle is a cylindrical tube. A pin is provided on the seat, and an elastic element pushes the pin through the seat surface. The hinge seat of the suitcase is fitted onto the wheel axle, pushing the suitcase to rotate around the wheel axle until it is against the main support, where the pin engages with a slot in the suitcase. A rotatable knob is provided on the seat; turning the knob pulls the pin back into the seat. This product provides a superior luggage cart, but there is room for improvement: when removing the suitcase, the user needs to turn the knob with one hand and the suitcase with the other, requiring two-handed operation. Summary of the Invention

[0004] The purpose of this invention is to provide a luggage cart with a pop-out function for the suitcase.

[0005] The purpose of this utility model is achieved as follows:

[0006] A luggage compartment vehicle includes a vehicle body and a luggage compartment. The vehicle body includes a main support and an auxiliary support that are hinged to each other. Both the main support and the auxiliary support are equipped with wheels. A handle and a seat are provided on the main support. A wheel axle is arranged laterally at the lower end of the main support, and wheels are provided on both sides of the wheel axle.

[0007] The lower end of the suitcase is provided with a hinge seat with an opening, and the wheel axle is either a round tube or arc-shaped at the position where it mates with the hinge seat; the seat is provided with a pin, and a spring pushes the pin to pass through the seat surface; the hinge seat of the suitcase is sleeved on the wheel axle, pushing the suitcase to rotate around the wheel axle until it is against the main bracket, and the pin engages with the slot of the suitcase; driving the pin, the pin can be retracted into the seat, the suitcase can rotate around the wheel axle and the suitcase can be removed;

[0008] The main support is equipped with an elastic element; when the luggage box is fixed to the vehicle body, the elastic element is limited between the luggage box and the main support, drives the pin, the pin and the slot separate, and the elastic element pushes the luggage box to rotate around the wheel axle, thereby causing the pin and the slot to misalign.

[0009] When the vehicle body is in the unfolded state, the drive pin and the slot separate, and the elastic element drives the luggage box to rotate, thereby causing the pin and the slot to misalign, while the luggage box still leans against the main bracket.

[0010] The elastic element is made of soft rubber, which is fixed to the main bracket. The deformation of the soft rubber itself provides a force for the misalignment of the pin and the slot.

[0011] The elastic element is a ring-shaped soft rubber, which is sleeved on the outside of the main support.

[0012] The annular soft rubber has an annular protrusion on its periphery, which can deform under stress.

[0013] The suitcase is provided with a recess that mates with an elastic element.

[0014] The seat is equipped with a rotating setting knob. Rotating the knob pulls the pin into the seat; or, the upper end of the pin is equipped with a pulling part. Driving the pulling part retracts the pin into the seat.

[0015] The knob has an arc-shaped groove on its side, and the pin has a longitudinal groove on its side. The positioning shaft passes through the arc-shaped groove and the longitudinal groove in sequence and connects the knob and the pin. When the knob is rotated, the positioning shaft moves along the arc-shaped groove, thereby pulling the pin into the seat. When the knob is released, the spring returns both the knob and the pin to their original positions. When an external force pushes the pin, the pin retracts into the seat. Under the action of the longitudinal groove, the pin does not drive the knob during its retraction.

[0016] It includes a fixed seat, a seat with a perforation, a fixed seat fixed in the perforation, a knob rotating in the gap between the seat and the fixed seat, and the rotating part of the knob located in the perforation; the side of the fixed seat is provided with a longitudinal groove, and the positioning shaft is limited in the longitudinal groove of the fixed seat.

[0017] The fixed seat has a recessed part inside, and the pin and spring are located in the recessed part; the knob, fixed seat, pin and spring are connected to form a whole, and the fastener fixes the whole to the lower end of the seat.

[0018] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0019] 1. This utility model employs an elastic element positioned between the suitcase and the main support frame. When the suitcase is secured by the latch, the elastic element deforms and compresses, compensating for the gap between the suitcase and the main support frame, thus reducing wobbling. When the latch and the slot separate, the elastic element resets and pushes the suitcase to rotate, thereby separating the latch and the slot. By incorporating this elastic element, the user can remove the suitcase with one hand. The user first drives the latch and the slot to separate, the suitcase is pushed out at a certain angle by the elastic element, and then the user can remove the suitcase, simplifying the user's operation.

[0020] 2. The elastic element of this utility model uses an annular soft rubber. During assembly, the manufacturer only needs to place the annular soft rubber on the outside of the main bracket, resulting in low assembly costs. Preferably, the annular soft rubber has an annular protrusion on its periphery. The annular protrusion can deform under force, allowing the annular soft rubber to stably adhere to the outer surface of the main bracket and also providing deformation functionality.

[0021] 3. The suitcase of this utility model is provided with a recess that cooperates with the elastic element. The recess avoids the elastic element from excessive deformation. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-12 As shown:

[0039] A luggage cart includes a body 1 and a luggage compartment 2. The body 1 includes a main support 11 and an auxiliary support 12 that are hinged to each other. The hinge method between the main support 11 and the auxiliary support 12 is not a key point of protection of this utility model, so this position is not described. This structure is already mature in existing products, and any commonly used structure on the market can be used. Both the main support 11 and the auxiliary support 12 are provided with wheels 19. The main support 11 is provided with a handle bar 13 and a seat 14. A wheel axle 111 is horizontally arranged at the lower end of the main support 11, and wheels 19 are arranged on both sides of the wheel axle 111. The lower end of the luggage compartment 2 is provided with a hinge seat 22 with an opening. The wheel axle 111 is a round tube or has an arc shape at the position where it mates with the hinge seat. Preferably, the wheel axle 111 is directly a metal round tube. Of course, a round tube can also be arranged at the position where the hinge seat mates, so that the luggage compartment 2 can rotate around this position. The seat 14 is equipped with a pin 3, which is pushed by a spring to extend through the lower surface of the seat 14. The hinge seat 22 of the suitcase is fitted onto the wheel axle 111, pushing the suitcase to rotate around the wheel axle until it is against the main support, and the pin engages with the slot of the suitcase. Driving the pin 3, the pin 3 can be retracted into the seat, and the suitcase 2 can rotate around the wheel axle 111 and be removed. The pin can move in several ways: Method 1, the upper end of the pin is provided with a pull part, and the pin can be moved by manually pulling the pull part of the pin. See the prior art CN202020469715.2, a multi-functional seatable trolley case. Method 2, as shown below, is provided with a knob, and the pin can be moved by rotating the knob. A lever can also be provided, which flips to move the pin. The specific way to move the pin is determined by the manufacturer. There are various ways to move the pin, and any one of them can be selected. Preferably, the suitcase has a groove that mates with the main support. When the suitcase is placed against the main support, the main support is confined within the groove to maintain its position and ensure structural stability.

[0040] The main support 11 is equipped with an elastic element 9. When the luggage box 2 is fixed to the vehicle body 1, the elastic element 9 is limited between the luggage box 2 and the main support 11, driving the pin 3 to separate from the slot 21. The elastic element 9 pushes the luggage box 2 to rotate around the wheel axle 111, thereby causing the pin 3 and the slot 21 to misalign. When the vehicle body 1 is in the unfolded state, the driving pin 3 and the slot 21 separate, and the elastic element 9 drives the luggage box 2 to rotate, thereby causing the pin 3 and the slot 21 to misalign. The luggage box 2 still rests against the main support 11.

[0041] The elastic element 9 is made of soft rubber, which is fixed to the main bracket 11. The deformation of the soft rubber itself provides a force for the misalignment of the pin and the slot. The manufacturer can lock the soft rubber to the main bracket with fasteners, or use a ring-shaped soft rubber as the elastic element, which is fitted onto the outside of the main bracket 11. A ring-shaped soft rubber is preferred because it is easier to install; it simply fits onto the outside of the main bracket, does not need to be aligned, and because it is fitted onto the outside, it will not fall off.

[0042] The annular soft rubber has an annular protrusion 91 on its periphery, which can deform under force. The suitcase 2 is provided with a recess that cooperates with the elastic element 9.

[0043] A setting knob 5 is rotatably mounted on the seat 14. Rotating the knob 5 pulls the pin 3 into the seat 14. The knob 5 has an arc-shaped groove 52 on its side, and the pin 3 has a longitudinal slot 31 on its side. The positioning shaft 7 passes through the arc-shaped groove 52 and the longitudinal slot 31 in sequence, connecting the knob 5 and the pin 3. Rotating the knob 5 moves the positioning shaft 7 along the arc-shaped groove 52, thereby pulling the pin 3 into the seat 14. Releasing the knob 5 causes the spring 6 to return both the knob 5 and the pin 3 to their original positions. External force pushes the pin 3, causing it to retract into the seat 14. Under the action of the longitudinal slot 31, the pin 3 does not drive the knob 5 during its retraction.

[0044] Includes a fixed base 4, a seat 14 with a through hole 141, the fixed base 4 is fixed at the through hole, a knob is rotated in the gap between the seat and the fixed base, and the rotating part of the knob is located in the through hole; the side of the fixed base is provided with a fixed base longitudinal groove 41, and the positioning shaft 7 is limited in the fixed base longitudinal groove 41.

[0045] The fixed base 4 has a recessed portion 42 inside, and the pin 3 and spring 6 are located inside the recessed portion 42. The inner side of the through hole 141 has a first step portion 142, and the knob 5 has a second step portion 51 that cooperates with the first step portion 142. The knob 5, fixed base 4, pin 3 and spring 6 are connected to form a whole, and fasteners fix the whole to the lower end of the seat 14. The fasteners can be bolts, screws and other components. The lower end of the pin 3 has a slope 32. Under the action of the slope 32, the suitcase can push the pin to retract into the seat.

[0046] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
