Description

Technical Field

[0001] This utility model relates to the field of children's bed technology, and in particular to a wheel set with brakes and a children's bed. Background Technology

[0002] Children's beds are often equipped with wheels at the bottom for easy movement. When children are playing in the bed, it's generally necessary to ensure the bed remains stable, so the wheels need to be braked.

[0003] Existing wheelsets with brakes typically use swivel casters, which are unsuitable for scenarios requiring only straight-line travel and no steering. Furthermore, existing wheelsets with brakes generally have complex structures. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a simple and easy-to-operate wheel set with brakes and a children's bed.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a wheel set with brakes, comprising:

[0006] Installation main body;

[0007] A roller is pivotally mounted on the mounting body, and the roller is provided with multiple brake holes;

[0008] A brake component is movably disposed on the mounting body. The brake component can be locked into the brake hole to restrict the rotation of the roller, and the brake component can be disengaged from the brake hole to release the restriction on the rotation of the roller.

[0009] A brake switch is movably disposed on the mounting body, and the brake switch can push against the brake component, so that the brake component is locked into the brake hole.

[0010] Furthermore, the brake component is positioned parallel to the pivot center direction of the roller.

[0011] Furthermore, multiple brake holes are provided on the side of the roller, and the multiple brake holes are evenly arranged with the pivot center of the roller as the center.

[0012] Furthermore, the brake component moves against the brake switch, and the brake switch is provided with a pushing part. The brake switch pushes the brake component through the pushing part, causing it to lock into the brake hole.

[0013] Furthermore, the braking component is configured as a brake pin;

[0014] A tension spring is provided between the brake pin and the mounting body. One end of the tension spring abuts against the mounting body, and the other end abuts against the brake pin. The force exerted by the tension spring on the brake pin causes the brake pin to maintain a tendency to move in its unlocking direction.

[0015] Furthermore, a ball head is provided at one end of the brake pin near the brake switch, and the tension spring is sleeved on the brake pin, with one end of it abutting against the ball head;

[0016] The brake switch is provided with an unlocking groove near the push part. When the contact position between the brake switch and the brake pin is switched from the push part to the unlocking groove, the tension spring drives the brake pin to disengage from the brake hole.

[0017] Furthermore, the unlocking groove is configured as a spherical concave shape, and a transitional spherical surface is provided near the unlocking groove;

[0018] When the brake switch drives the brake pin to lock toward the brake hole, the contact position between the brake switch and the ball head changes from the unlocking groove, through the transition spherical surface, to the pushing part;

[0019] The contact position between the brake switch and the ball head changes from the pushing part, through the transition spherical surface, to the unlocking groove, and the brake pin is released.

[0020] Furthermore, the brake switch is rotatably mounted on the mounting body, and the rotation center of the brake switch is parallel to the pivot center of the roller;

[0021] The pushing part, the unlocking groove, and the transition spherical surface are all provided on the side of the brake switch. A toggle protrusion protrudes outward from the brake switch, and the user rotates the brake switch by toggling the toggle protrusion.

[0022] Furthermore, the mounting body includes a connector and two mounting seats, the two mounting seats being detachably and symmetrically arranged at both ends of the connector;

[0023] The two mounting bases are respectively provided with the roller, the brake component and the brake switch.

[0024] This utility model also proposes a children's bed, wherein the bottom of the children's bed is equipped with the aforementioned wheel set with brakes.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] In this invention, the roller is pivotally mounted on the mounting body, and the brake and brake switch are movably mounted on the mounting body. Operating the brake switch locks the brake into the brake hole on the roller, restricting its pivoting and preventing rotation. Furthermore, operating the brake switch releases the brake from the brake hole, allowing the roller to pivot normally. The overall structure of the wheelset is simple, suitable for scenarios requiring only straight-line travel, and offers a more upscale feel while being easy for users to operate.

[0027] In this invention, a tension spring is provided between the brake component and the mounting body. The brake switch has an unlocking groove and a pushing part. When the brake switch abuts against the brake component through the pushing part, the brake component is locked into the brake hole and is in the braking state. When the brake switch is rotated until the unlocking groove aligns with the brake component, the brake component retracts under the action of the tension spring and is pulled out of the brake hole, switching to the released state.

[0028] In this invention, the unlocking groove is set as a spherical groove, and a transition spherical surface is provided between the unlocking groove and the pushing part. It cooperates with the ball head of the brake pin. When the ball head slides between the pushing part, the transition spherical surface and the unlocking groove, it slides smoothly, ensuring smooth braking and unlocking movements and a good user operating feel.

[0048] Example 1:

[0049] like Figures 1-4 As shown, a wheel assembly with brakes according to this embodiment includes: a mounting body 100, a roller 200, a brake component 300, a brake switch 400, and a tension spring 500. The roller 200 is pivotally mounted on the mounting body 100 and has multiple brake holes 20. The brake component 300 is movably mounted on the mounting body 100, and can be locked into the brake holes 20 to restrict the pivoting of the roller 200. The brake component 300 can also disengage from the brake holes 20 to release the pivoting restriction on the roller 200. The brake switch 400 is movably mounted on the mounting body 100 and can push against the brake component 300, locking the brake component 300 into the brake holes 20.

[0050] In practical use, the roller 200 of this embodiment is pivotally mounted on the mounting body 100, and the brake component 300 and brake switch 400 are both movably mounted on the mounting body 100. By operating the brake switch 400, the brake component 300 can be locked into the brake hole 20 on the roller 200, restricting the pivoting of the roller 200 and ensuring that the roller 200 cannot rotate. Furthermore, by operating the brake switch 400, the brake component 300 can be released from the brake hole 20 on the roller 200, releasing the pivoting restriction on the roller 200, allowing the roller 200 to pivot normally. The overall structure of the wheelset is simple, suitable for scenarios requiring only straight-line travel, and the wheelset is more upscale and easy for users to operate.

[0051] In this embodiment, the brake component 300 is positioned parallel to the pivot center of the roller 200. Specifically, the roller 200 is hinged to the mounting body 100 via a pivot axis, meaning the pivot center of the roller 200 is its pivot axis. Taking the normal use of the wheel axle on a children's bed as a reference, the pivot center of the roller 200 is parallel to the ground. Therefore, the roller 200 in this embodiment is a straight-moving roller, not a swivel wheel. Consequently, the brake component 300 is also positioned parallel to the ground.

[0052] Multiple brake holes 20 are provided on the side of the roller 200, and the multiple brake holes 20 are evenly arranged with the pivot center of the roller 200 as the center, so that the brake component 300 can be aligned and locked into one of the brake holes 20 no matter where the roller 200 rolls, because braking may be required at any time, ensuring the reliability of the structure.

[0053] like Figures 3-7 As shown, the brake component 300 and the brake switch 400 are movably abutted against each other. The brake component 300 is telescopically mounted on the mounting body 100, and the brake switch 400 is rotatably mounted on the mounting body 100 via a pivot. The rotation center of the brake switch 400 is parallel to the pivot center of the roller 200, i.e., parallel to the ground. The brake switch 400 is provided with a pushing part 41, which pushes the brake component 300 into the brake hole 20. Specifically, the pushing part 41 is located on the side of the brake switch 400, and its side is set as a plane, through which the brake component 300 is pushed.

[0054] Furthermore, the brake component 300 is configured as a brake pin. A tension spring 500 is provided between the brake pin and the mounting body 100. The tension spring 500 is sleeved on the brake pin, with one end of the tension spring 500 abutting against the mounting body 100 and the other end abutting against the brake pin. The force exerted by the tension spring 500 on the brake pin causes the brake pin to maintain a tendency to move in its unlocking direction.

[0055] Furthermore, a ball head 30 is disposed at one end of the brake pin near the brake switch 400, and one end of the tension spring 500 abuts against the ball head 30. The brake switch 400 has an unlocking groove 42 near the pushing part 41, which is a ball-shaped recess. When the contact position between the brake switch 400 and the brake pin changes from the pushing part 41 to the unlocking groove 42, the tension spring 500 drives the brake pin to disengage from the brake hole 20. That is, when the brake pin needs to be withdrawn from the brake hole 20, the brake switch 400 rotates until the unlocking groove 42 aligns with the ball head 30 of the brake pin. Under the action of the tension spring 500, the brake pin retracts, its ball head 30 extends into the unlocking groove 42, and the end of the brake pin away from the ball head 30 disengages from the brake hole 20.

[0056] In practical use, this embodiment includes a tension spring 500 between the brake component 300 and the mounting body 100. The brake switch 400 has an unlocking groove 42 and a pushing part 41. When the brake switch 400 abuts against the brake component 300 through the pushing part 41, the brake component 300 is locked into the brake hole 20 and is in a braking state. When the brake switch 400 is rotated until the unlocking groove 42 aligns with the brake component 300, the brake component 300 retracts under the action of the tension spring 500, is pulled out of the brake hole 20, and switches to the released state.

[0057] A transition spherical surface 43 is provided near the unlocking groove 42 on the brake switch 400. The radius of the transition spherical surface 43 is smaller than the radius of the unlocking groove 42, and the unlocking groove 42 is deeper than the recess depth of the transition spherical surface 43. When the brake switch 400 drives the brake pin to lock into the brake hole 20, the contact position between the brake switch 400 and the ball head 30 changes from the unlocking groove 42, through the transition spherical surface 43, to the pushing part 41. The contact position between the brake switch 400 and the ball head 30 changes from the pushing part 41, through the transition spherical surface 43, to the unlocking groove 42, and the brake pin is released. That is, when the user drives the brake switch 400 to brake, the contact position between the brake switch 400 and the brake pin changes from the unlocking groove 42, through the transition spherical surface 43, and then to the pushing part 41. When the user drives the brake switch 400 to release the brake, the contact position between the brake switch 400 and the brake pin changes from the pushing part 41, through the transition spherical surface 43, to the unlocking groove 42.

[0058] In actual use, the unlocking groove 42 of this embodiment is set as a ball groove, and a transition ball surface 43 is provided between the unlocking groove 42 and the pushing part 41. It cooperates with the ball head 30 of the brake pin. When the ball head 30 slides between the pushing part 41, the transition ball surface 43 and the unlocking groove 42, it slides smoothly, ensuring smooth braking and unlocking movements and good user operation feel.

[0059] Specifically, in this embodiment, the pushing part 41, the unlocking groove 42, and the transition spherical surface 43 are all provided on the side of the brake switch 400. A toggle protrusion 40 protrudes outward from the brake switch 400, and the user rotates the brake switch 400 by toggling the toggle protrusion 40.

[0060] The mounting body 100 includes a connector 11 and two mounting seats 10. The connector 11 is configured as a connecting pipe, and the two mounting seats 10 are detachably and symmetrically arranged at both ends of the connector 11. The two mounting seats 10 are respectively provided with the roller 200, the brake component 300, and the brake switch 400.

[0061] like Figure 8As shown, the mounting base 10 is provided with an elastic buckle 1, and a corresponding slot is provided on the connecting pipe. The elastic buckle 1 and the slot are detachably connected. When it is necessary to remove the mounting base 10, the elastic buckle 1 can be pressed to disengage it from the slot, and then the mounting base 10 can be pulled out. In order to simplify the structure of the mold and facilitate mold opening, the mounting base 10 includes an inner base 10A and an outer base 10B, which are fixedly connected.

[0062] In actual use, when the roller 200 is in the released state, the ball head 30 of the brake pin abuts against the unlocking groove 42 of the brake switch 400. When braking is required, pressing down on the actuating protrusion 40 causes the brake switch 400 to push against the ball head 30 via the transition ball surface 43 and the abutting part 41, causing the brake pin to move closer to the brake hole 20 and extend into the brake hole 20, restricting the pivoting of the roller 200. The roller 200 cannot rotate, and the tension spring 500 is compressed during this process. When releasing the brake, pushing up on the actuating protrusion 40 causes the brake switch 400 to abut against the ball head 30 via the transition ball surface 43 and the unlocking groove 42. Under the action of the tension spring 500, the brake pin retracts, moves away from the brake hole 20, and is pulled out of the brake hole 20, releasing the pivoting restriction of the roller 200, allowing the roller 200 to rotate and move.

[0063] Example 2:

[0064] like Figure 1 As shown, in a child bed of this embodiment, the bottom of the child bed is equipped with a set of wheels with brakes as in Embodiment 1. Specifically, two sets of such sets of wheels with brakes are symmetrically arranged at the bottom of the child bed to facilitate moving the child bed.

[0065] In this solution, the wheelset with brakes has a simple overall structure, is suitable for scenarios where only straight-line travel is required, is more upscale, and is easy for users to operate.
