All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-5, a quick-opening type luggage wheel braking mechanism comprises a luggage wheel braking executing component 1, a braking cable 2 and a braking cable pulling component 3, wherein the luggage wheel braking executing component 1 is mounted on a luggage wheel 4 and comprises a movable braking arm 1a, a spring 1b and a pin shaft 1c, the movable braking arm 1a is rotatably mounted in a luggage wheel carrier 4a through the pin shaft 1b, a traction end 1a1 of the movable braking arm 1a is connected with the braking cable 2, a braking end 1a2 points to the luggage wheel 4b or the luggage wheel 4c but keeps the braking end thereof suspended and does not contact the luggage wheel shaft 4c or the wheel 4b (the spring 1b is sleeved on the braking cable and is arranged between the traction end 1a1 of the movable braking arm and the luggage wheel carrier, so that the traction end 1a1 of the movable braking arm 1a keeps a free state under the elastic force of the spring 1b, and also that the braking end 1a2 does not contact the luggage wheel 4b or the luggage wheel axle 4 c); the brake cable traction component 3 is arranged on the side surface of the trunk body according to actual needs (mainly considering that a passenger can easily kick the luggage box with feet at any time during pushing), and the brake cable traction component 3 comprises an installation seat 3a embedded and installed on the trunk body, a kick moving part 3b embedded and installed in the installation seat 3a from outside to inside in sequence, a traction moving part 3c matched with the kick moving part 3b and a guide pin 3 e; as shown in fig. 2, oblique teeth 3f with mutually matched tooth surfaces are arranged between the kick moving piece 3b and the drawing moving piece 3b, when the kick moving piece 3b is close to the drawing moving piece 3c under the action of external force (for example, a passenger lifts the kick to the kick moving piece), the tooth surfaces of the mutually matched oblique teeth relatively slide to enable the drawing moving piece 3c to move in a space perpendicular to the moving direction of the kick moving piece 3b, and the brake cable 2 is drawn due to the movement of the drawing moving piece 3c, and the brake cable 2 draws the movable brake arm 1a to apply brake force to the trunk wheel 4b or the trunk wheel shaft 4 c; in order to maintain the braking state, the movable element 3c needs to be displaced and then kept at a position after the displacement, and therefore, as shown in fig. 3, a guide groove 3c1 is provided on the rear surface of the movable element 3c, and the guide groove is closedClosed "M" shape or

And in a free state, when the traction moving part moves in a vertical direction, the guide pin moves from a low-position stop position (B) to a high-position stop position (A) along the guide groove, a concave position is arranged at the position of the A point, the traction moving part which moves just moves to enable the guide pin to hook the concave position of the A point, the traction state of the traction moving part on the brake cable can be kept, the foot-kicking moving part is pressed (kicked) again, the traction moving part can also move in a direction perpendicular to the moving direction of the foot-kicking moving part under the action of oblique teeth, and at the moment, the guide pin continues to move along the guide groove, finally hooks the low position of the B point of the guide groove, and the brake executing component is in a non-braking state.

It should be noted that, the design of the guide groove 3c1 is mainly to enable the guide pin to smoothly stay in two specific groove positions (limit grooves) during the movement of the pulling movable member, wherein one stop position (point a) enables the brake cable to be tensioned, and the other stop position (point B) enables the brake cable to be relaxed. The concept of the present invention should be clearly shown in conjunction with fig. 3, and any design based on this concept should be considered equivalent.

It should be emphasized that, in the application, as shown in fig. 2, the brake cable 2 is not directly connected to the pulling movable member 3c, the spring is disposed at the end of the brake cable 2, the brake cable 2 passes through the pulling movable member 3c, and the spring acts on the end of the brake cable 2 and the pulling movable member 3c, so that the design is very ingenious, if the design is not adopted, the brake cable 2 is already tensioned in the braking state, and if the braking is to be released, the traveler needs to kick the foot to kick the movable member 3B, but since the brake cable in the braking state is already tensioned, the pulling cannot continue to move downwards (that is, the stopping guide pin is blocked at the high position B), therefore, the application adopts the spring as a connecting member for connecting the brake cable and the pulling movable member, on one hand, the movable member can still have a certain degree of freedom in the braking state, on the other hand, the brake cable has enough tension to keep the brake cable tensioned under the braking state.

Example two

The second embodiment is the same as the first embodiment in the design of the brake actuator and the brake cable, except for the design of the brake cable pulling assembly, in order to realize the action of periodically pulling/releasing the movable brake arm of the brake cable after the brake cable is circularly pressed (i.e. kicked by a foot to pull the brake cable pulling assembly), the invention also provides the brake cable pulling assembly shown in fig. 6, which comprises a kicked movable part 3b, a movable rotating wheel 3h and a brake cable pulling guide wheel 3g movably arranged on the side edge of the rotating wheel, wherein the kicked movable part 3b and the movable rotating wheel 3h still adopt the mode of the skewed tooth fit, the movable rotating wheel 3c rotates as long as the kicked movable part 3b is pressed (the prior art provides a plurality of design schemes, the skewed tooth design of the first embodiment can also be adopted), and at the moment, the brake cable pulling guide wheel 3g adaptively moves along the outer contour of the movable rotating wheel 3h, it should be noted that the brake cable pulling guide wheel 3g is limited to move in the direction of the dotted line only by the bracket 3i, and the brake cable 2 passes through the brake cable pulling guide wheel 3g, so that once the position of the brake cable pulling guide wheel 3g changes, the brake cable 2 can tighten or loosen the movable brake arm accordingly, thereby realizing braking or releasing braking. It should be noted that, in order to maintain the braking or braking releasing state, the outline design of the movable wheel 3c is a place which needs to be paid particular attention, as shown in fig. 7, a plurality of stopping positions (a 'and B') of the brake cable pulling guide wheel 3g are arranged on the outer peripheral surface of the movable wheel 3h, when the brake cable pulling guide wheel 3g is at a ', the brake cable 2 is tensioned, when the brake cable pulling guide wheel 3g is at B', the brake cable 2 is in a loose state, because the outlines of the stopping positions (a 'and B') are designed into a concave shape, the brake cable pulling guide wheel 3g can maintain the state in the stopping positions, and the state change can not occur until the movable wheel 3c is rotated again when the movable member 3B is kicked by a foot to be pressed.

It is also an object of the present invention to provide a luggage case comprising a body and a luggage wheel, and any of the aforementioned quick-open luggage wheel brake mechanisms.
