Description

Technical Field

[0001] This utility model relates to the field of hand-pushed vehicle technology, and in particular to a food cart. Background Technology

[0002] On large transport vehicles such as airplanes, high-speed trains, and regular trains, food carts are typically used to carry food. Attendants push the food carts through the aisles so that passengers can easily purchase food.

[0003] When passengers purchase food, the flight attendant needs to brake and secure the food cart. In this type of food cart, movable brake pads are installed on one side of the wheels. The flight attendant presses the brake pads with their foot to make them press against the wheels. The brake pads use friction to prevent the wheels from rotating, thus braking and securing the food cart.

[0004] However, the use of brake pads will accelerate wheel wear and shorten the wheel's lifespan. Utility Model Content

[0024] The following is for reference. Figures 1 to 6 The food truck described in this application is described in detail.

[0025] refer to Figures 1 to 4 According to an embodiment of the present invention, a food cart includes a vehicle body 100, a wheel assembly 200, and a brake assembly 300. The vehicle body 100 has a mounting base 110. The wheel assembly 200 includes a wheel 210, a rotating shaft 220, and a limiting member 230. The wheel 210 and the limiting member 230 are both sleeved on the rotating shaft 220. The rotating shaft 220 is rotatably mounted on the mounting base 110. The limiting member 230 is provided with multiple snap-fit ​​structures, which are spaced apart circumferentially around the rotating shaft 220. The brake assembly 300 is movably mounted on the mounting base 110. The brake assembly 300 has a snap-fit ​​member 310. Under the action of external force, the brake assembly 300 can move so that the snap-fit ​​member 310 snaps with one of the snap-fit ​​structures and prevents the wheel 210 from rotating.

[0026] Understandably, during the use of the food cart of this application, when the user needs to brake the food cart, the user can use their foot to drive the brake assembly 300 to move relative to the mounting base 110, so that the locking member 310 moves closer to the limiting member 230 and engages with one of the locking structures on the limiting member 230. At this time, the locking member 310 can prevent the limiting member 230 from continuing to rotate with the rotating shaft 220, thereby locking and fixing the limiting member 230, the rotating shaft 220 and the wheel 210, and the entire food cart is in a braked and stationary state. When the user needs the food cart to be released from the braked and stationary state, the user can release the force applied to the brake assembly 300, so that the brake assembly 300 drives the locking member 310 away from the limiting member 230, and releases the engagement between the locking member 310 and the locking structure. At this time, the limiting member 230 can rotate normally with the rotating shaft 220 and the wheel 210. In this state, the food cart can move normally under the push of the user.

[0027] It is understood that in the food cart of this application, since both the wheel 210 and the limiting member 230 are sleeved on the rotating shaft 220, and the limiting member 230 is provided with multiple snap-fit ​​structures, when the snap-fit ​​member 310 snaps into one of the snap-fit ​​structures, the limiting member 230 can be locked and fixed, thereby locking and fixing the rotating shaft 220 and the wheel 210. The snap-fit ​​member 310 does not need to directly contact the wheel 210, thereby reducing the wear on the wheel 210 and extending the service life of the wheel 210.

[0028] In some embodiments of this utility model, reference is made to Figure 3 The snap-fit ​​structure is a slot 231 provided on the circumferential surface of the limiting member 230. Under the action of external force, the brake assembly 300 can move so that the snap-fit ​​member 310 snaps into one of the slots 231.

[0029] It is understandable that, since the slots 231 are spaced apart along the circumference of the limiting member 230, there is always a slot 231 on the moving path of the locking member 310 during the rotation of the limiting member 230 around the rotating shaft 220. When the user drives the brake assembly 300 at any time, there is always a slot 231 on the limiting member 230 that can accommodate the locking member 310, so as to lock and fix the limiting member 230 with the locking member 310.

[0030] In some other embodiments of this utility model, the snap-fit ​​structure can also be a snap-fit ​​hole provided on the limiting member 230. In this case, the snap-fit ​​holes are distributed circumferentially around the limiting member 230 around the rotating shaft 220, and the snap-fit ​​member 310 can be inserted into one of the snap-fit ​​holes to achieve locking and fixing of the limiting member 230.

[0031] In some embodiments of this utility model, reference is made to Figure 6 The brake assembly 300 also includes a mounting member 320, which is hinged to the mounting base 110, and the rotation axis of the mounting member 320 is parallel to the axis of the rotating shaft 220. A snap-fit ​​member 310 is provided on the mounting member 320. Under the action of external force, the mounting member 320 can rotate so that the snap-fit ​​member 310 snaps into one of the snap-fit ​​structures.

[0032] Understandably, when the user needs to brake the food cart while pushing it forward, the user can use their foot to drive the mounting piece 320 to rotate relative to the mounting base 110, thereby causing the latching piece 310 to approach the limiting piece 230 and pass through the slot 231 on the limiting piece 230 to brake the food cart.

[0033] Understandably, since the mounting component 320 is hinged to the mounting base 110, it makes it more convenient for the user to drive the mounting component 320.

[0034] To facilitate user-driven operation of the mounting component 320, in some embodiments of this utility model, reference is made to... Figure 6The brake assembly 300 also includes a transmission component 330, which is rotatably sleeved on the rotating shaft 220 and is connected to the connecting part 321 of the mounting component 320. The connecting part 321 is located on the radial side of the rotation axis of the mounting component 320. Under the action of external force, the transmission component 330 can drive the mounting component 320 to rotate relative to the mounting base 110.

[0035] Understandably, when the user steps on the transmission component 330, causing it to rotate forward relative to the rotating shaft 220, the transmission component 330 drives the mounting component 320 to move. The locking member 310 on the mounting component 320 approaches the limiting member 230 and can be inserted into the slot 231 of the limiting member 230. At this time, the wheel 210 is locked and fixed, and the food cart is stopped. When the user steps on the transmission component 330, causing it to rotate in the opposite direction relative to the rotating shaft 220, the transmission component 330 drives the mounting component 320 to move. The locking member 310 on the mounting component 320 moves away from the limiting member 230 and can disengage from the slot 231 of the limiting member 230. At this time, the wheel 210 can rotate normally, and the food cart can move normally.

[0036] In a further embodiment of this utility model, reference is made to... Figures 4 to 6 The transmission component 330 is hinged to the connecting part 321, and the connecting part 321 is located on the radial side of the rotating shaft 220; the mounting base 110 is provided with an elongated hole 111, and the mounting component 320 has a transmission pin 322, which is slidable and rotatable and passes through the elongated hole 111.

[0037] Understandably, when the user drives the transmission component 330 to rotate forward around the shaft 220, the transmission component 330 can drive the connecting part 321 of the mounting component 320 to rotate forward around the shaft 220. At this time, the mounting component 320 can rotate around the transmission pin 322, and the transmission pin 322 can slide synchronously along the elongated hole 111 to drive the snap-fit ​​component 310 to approach the limiting component 230 and insert the snap-fit ​​component 310 into the snap-fit ​​groove 231 of the limiting component 230 to achieve braking of the food cart.

[0038] It is understandable that the elongated hole 111 is designed so that when the transmission component 330 drives the mounting component 320 to move, the mounting component 320 can move along the elongated hole 111, so that the snap-fit ​​component 310 can accurately approach or move away from the limiting component 230 along the elongated hole 111.

[0039] In some embodiments of this utility model, reference is made to Figure 5 The snap-fit ​​component 310 is mounted on the transmission pin 322.

[0040] It is understandable that by placing the snap-fit ​​310 on the transmission pin 322, the snap-fit ​​310 can move closer to or further away from the limiting member 230 as the transmission pin 322 slides along the elongated hole 111, so that the snap-fit ​​310 can be inserted into or disengaged from the slot 231 on the limiting member 230.

[0041] In some embodiments of this utility model, reference is made to Figure 6 The mounting component 320 is provided with a relief groove 323, which can accommodate the rotating shaft 220.

[0042] It should be noted that during the movement of the mounting component 320, if the range of motion of the mounting component 320 is small, the snap-fit ​​component 310 on the mounting component 320 will be difficult to fully snap into the slot 231 of the limiting component 230. If the range of motion of the mounting component 320 is large, the mounting component 320 will easily interfere with the rotating shaft 220.

[0043] It is understandable that by providing a clearance groove 323 on the mounting bracket, and the clearance groove 323 being able to accommodate the rotating shaft 220, the interference between the mounting component 320 and the rotating shaft 220 is reduced while ensuring that the mounting component 320 has a large range of motion.

[0044] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The brake assembly 300 also includes a reset member 340, which is connected to the mounting member 320 and the mounting base 110 respectively, and is used to provide a reset force to keep the snap-fit ​​member 310 detached from the snap-fit ​​structure.

[0045] Understandably, by setting the reset component 340, when the user needs to release the locked state of the wheel 210, after the user releases his foot, the mounting component 320 can automatically reset under the action of the reset component 340, so that the locking component 310 can automatically disengage from the slot 231 of the limiting component 230, saving time and effort.

[0046] In a further embodiment of this utility model, the reset member 340 is a spring, which is disposed in the elongated hole 111 and extends along the length direction of the elongated hole 111. The opposite ends of the spring are respectively connected to the hole wall of the elongated hole 111 and the transmission pin 322.

[0047] Understandably, springs have a simple structure and are inexpensive.

[0048] It is understandable that by placing the spring inside the elongated hole 111, the elongated hole 111 can limit the spring, so that the spring can deform stably along the extension direction of the elongated hole 111.

[0049] In some embodiments of this utility model, reference is made to Figure 6 The brake assembly 300 also includes a foot pedal 350, which is mounted on the transmission member 330.

[0050] Understandably, the foot pedal 350 is designed so that the user can smoothly drive the transmission component 330 to move by stepping on the foot pedal 350, thereby smoothly braking the food cart.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
