DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. In response to the problems existing in the prior art, the following solutions are proposed:

[0040] Example 1, as Figure 1-5 As shown, a brake drive component is mainly used on a suitcase to control the braking of the corner casters of the suitcase. Its structure includes an outer shell 1, in which a slide button 3 and a traction box 2 are slidably installed. The slide button 3 is a component operated by the user, and the traction box 2 is connected to a plurality of brake cables 21. By pulling the brake cables 21, the brake assembly on the corner caster can be driven to brake, thereby achieving the purpose of braking the corner caster.

[0041] A transmission assembly 4 is provided between the slide button 3 and the traction box 2. The transmission assembly 4 can transmit the force of the movement of the slide button 3 to the traction box 2, thereby realizing the movement of the traction box 2 in the outer shell 1; the slide button 3 is also provided with a locking assembly 5. The purpose of providing the locking assembly 5 is to lock the slide button 3 so that it no longer slides when the slide button 3 moves to the locking position; the traction box 2 is also provided with a reset compensation mechanism 6. The reset compensation mechanism 6 can reset and compensate the traction box 2 and the slide button 3 after the locking assembly 5 is unlocked, thereby solving the problem of incomplete reset of the traction box 2 and the slide button 3.

[0042] refer to Figure 3It can be seen that in this embodiment, a brake spring 22 is provided at the end of the brake cable 21. One end of the brake spring 22 is against the inner wall of the chamber of the traction box 2, and the other end is connected to the end of the brake cable 21. The brake spring 22 can serve the purpose of shock absorption. The provision of the brake spring 22 can reduce the hard impact applied by the brake cable 21 to the traction box 2.

[0043] It is worth noting that in this embodiment, the transmission assembly 4 adopts a gear assembly structure, the purpose of which is to be able to transmit the force that amplifies the sliding of the slide button 3 to the traction box 2 to drive the brake assembly on the corner wheel to brake. When the slide button 3 moves to a predetermined position, the locking assembly 5 is activated, and the locking assembly 5 can lock the slide button 3 so that it no longer slides. By locking the slide button 3, the traction box 2 and the brake cable 21 are locked. Such a design allows the user to pull the brake cable 21 without always pushing the slide button 3 hard, thereby achieving the purpose of braking the corner wheel.

[0044] Specifically, the locking assembly 5 can release the locking state of the slide button 3, and the slide button 3 can continue to slide after the locking state is released; when the locking assembly 5 is released from the locking state, the reset compensation mechanism 6 can automatically reset the traction box 2.

[0045] To be more specific: the reset compensation mechanism 6 includes an elastic component. In this embodiment, when the slide button 3 is slid for braking, the elastic component will store elastic potential energy. After the locked state is released, the elastic potential energy stored in the elastic component pushes the traction box 2 and the slide button 3, thereby completely resetting the traction box 2 and the slide button 3.

[0046] In specific use, a user slides the slider 3, which drives the traction box 2 via the transmission assembly 4. The traction box 2 pulls the internally connected brake cable 21, which in turn activates the brake mechanism on the caster. This achieves the purpose of controlling the brake mechanism on the caster via the slider 3. Subsequently, when the slider 3 slides to a predetermined position, the locking assembly 5 automatically enters a locked state, locking the slider 3 and the traction box 2. This prevents the user from continuously pushing the slider 3 to pull the brake cable 21, thereby braking the caster. During the braking process of the slider 3 and the traction box 2, the elastic component in the reset compensation mechanism 6 stores elastic potential energy. Once the lock is released, the elastic component releases this potential energy, pushing the slider 3 and the traction box 2 back into position.

[0047] Example 2, as Figure 3-4As shown, the transmission assembly 4 includes: an active rack 41, a transmission gear 1 42, and a transmission rack 45. The active rack 41 is disposed on the edge of the slider 3, the transmission rack 45 is fixedly connected to the traction box 2, and the transmission gear 1 42 is rotatably mounted on the outer shell 1. The active rack 41 and the transmission gear 1 42 are meshed with each other, and the transmission gear 1 42 is meshed with the mutual transmission rack 45. The slider 3 can drive the transmission gear 1 42 to rotate via the active rack 41. The rotation of the transmission gear 1 42 drives the transmission rack 45 to move linearly, thereby driving the traction box 2 to move linearly.

[0048] When the movement starts, the user slides the slider 3, and the slider 3 drives the transmission gear 1 42 to rotate through the active rack 41, and the rotation of the transmission gear 1 42 drives the transmission rack 45 to move linearly, thereby driving the traction box 2 to move linearly, and then the traction box 2 pulls the brake cable 21 to brake the corner wheel.

[0049] Example 3, as Figure 5-6 As shown, the transmission assembly 4 also includes a second transmission gear 43 and a third transmission gear 44. The second and third transmission gears 43 and 44 are rotatably connected to the outer housing 1 and coaxially fixedly connected. The second transmission gear 43 meshes with the active rack 41 on the slider 3, while the transmission rack 45 meshes with the transmission rack 45 on the traction box 2. The slider 3 can drive the second transmission gear 43 to rotate via the active rack 41, thereby driving the third transmission gear 44. The rotation of the third transmission gear 44 drives the transmission rack 45 to move linearly, ultimately driving the traction box 2 to move linearly. Because the diameter of the second transmission gear 43 is larger than that of the third transmission gear 44, the transmission rack 45 and the traction box 2 move at a slower speed than the active rack 41 and the slider 3, while the transmission rack 45 and the traction box 2 have a greater force than the active rack 41 and the slider 3.

[0050] When the movement starts, the user slides the slider 3, and the slider 3 drives the transmission gear 2 43 to rotate through the active rack 41, and the transmission gear 2 43 drives the transmission gear 3 44 to rotate. The rotation of the transmission gear 3 44 drives the transmission rack 45 to move linearly, and then drives the traction box 2 to move linearly. Then the traction box 2 pulls the brake cable 21 to brake the corner wheel. The force of the traction box 2 pulling the brake cable 21 is greater than the force of the user sliding the slider 3.

[0051] Example 4, as Figure 8-10As shown, the locking assembly 5 includes a button 51, a lock tongue 52, and a lock catch 53. A sliding cavity 11 is provided within the outer housing 1, and the lock tongue 52 is slidably mounted within the sliding cavity 11. Furthermore, a limit hole 521 is defined in the lock tongue 52, and a limit rod 1 is fixedly mounted within the sliding cavity 11. The limit rod 1 extends through the limit hole 521 and is slidably connected thereto. The provision of the limit hole 521 and the limit rod 1 ensures that the lock tongue 52 slides more stably within the sliding cavity 11. A lock tongue spring 1 is fixedly mounted between the lock tongue 52 and the bottom of the sliding cavity 11, pushing the lock tongue 52, causing it to extend naturally.

[0052] A lock catch 53 is provided within the outer housing 1 along the path of movement of the slide button 3, and is capable of interlocking with the lock tongue 1 52. The lock tongue 1 52 is provided with an inclined sliding surface 1 522, and the lock catch 53 is provided with an inclined sliding surface 2 531 parallel to and corresponding to the inclined sliding surface 1 522. When the slide button 3 is pushed until the inclined sliding surface 1 522 and the inclined sliding surface 2 531 are in contact, and the slide button 3 is further pushed, the inclined sliding surface 1 522 and the inclined sliding surface 2 531 slide against each other, and the lock catch 53 pushes the lock tongue 1 52 deeper into the sliding cavity 11 via the inclined sliding surface 1 522 and the inclined sliding surface 2 531, at which time the lock tongue spring 1 contracts. When the inclined sliding surface 1 522 completely slides past the inclined sliding surface 2 531, the lock tongue spring 1 expands, further pushing the lock tongue 1 52 out of the sliding cavity 11, thereby interlocking the lock tongue 1 52 and the lock catch 53. At this time, the positions of the slide button 3 and the traction box 2 are locked, and the traction box 2 is in a position where the brake cable 21 is tightened.

[0053] The locking assembly 5 also includes a button 51. The sliding button 3 includes a button housing 31. The button 51 is slidably mounted within the button housing 31. The button 51 is located directly above the lock tongue 1 52. A pressing plate 511 is disposed below the button 51, covering the entire sliding range of the lock tongue 1 52. The provision of the pressing plate 511 ensures that the button 51 can press the lock tongue 1 52 regardless of the sliding position of the lock tongue 1 52. When the button 51 is pressed, the button 51 presses the lock tongue 1 52 via the pressing plate 511. The lock tongue 1 52 then slides into the sliding cavity 11, and the lock tongue spring 1 contracts, releasing the lock tongue 1 52 and the lock catch 53 from the locked state.

[0054] In practice, the user slides the slider 3. When the slider 3 slides until the inclined sliding surface 1 522 and the inclined sliding surface 2 531 are aligned, the slider 3 is further pushed. The inclined sliding surface 1 522 and the inclined sliding surface 2 531 slide against each other, and the lock catch 53 pushes the lock tongue 1 52 deeper into the sliding cavity 11 via the inclined sliding surface 1 522 and the inclined sliding surface 2 531. At this time, the lock tongue spring 1 contracts. When the inclined sliding surface 1 522 completely slides past the inclined sliding surface 2 531, the lock tongue spring 1 extends, further pushing the lock tongue 1 52 out of the sliding cavity 11, thereby locking the lock tongue 1 52 with the lock catch 53. When the user wants to release the lock, they only need to press the button 51. The button 51 presses the lock tongue 1 52 via the pressing plate 511. At this time, the lock tongue 1 52 slides into the sliding cavity 11, the lock tongue spring 1 contracts, and the lock tongue 1 52 and the lock catch 53 are released from the locked state.

[0055] Example 5, as Figure 5-7 As shown, the locking assembly 5 includes a button 51, a second locking tongue 54, and a locking notch 55. The sliding button 3 includes a button housing 31, within which the second locking tongue 54 is slidably mounted. A second locking tongue spring is fixedly mounted between the second locking tongue 54 and the button housing 31, allowing the second locking tongue 54 to extend naturally. A locking notch 55 is provided within the outer housing 1 along the path of movement of the sliding button 3, into which the second locking tongue 54 can be inserted. When the second locking tongue 54 slides into the locking notch 55, the second locking tongue spring pushes the second locking tongue 54 into the locking notch 55, thereby engaging the second locking tongue 54 and the locking notch 55. At this point, the positions of the sliding button 3 and the traction box 2 are locked, and the traction box 2 is in a position to tighten the brake cable 21.

[0056] The slide button 3 includes a button housing 31, within which the button 51 is slidably mounted. A second locking tongue 54 defines an oblique sliding opening 541 facing the button 51. A third oblique sliding surface 513 is defined at the bottom of the button 51. The oblique sliding opening 541 and the third oblique sliding surface 513 are parallel to each other. When the button 51 is pressed, the second locking tongue 54 retracts, and the slide button 3 and the traction box 2 return to a free state. A second limiting hole 512 is defined in the button 51. A second limiting rod is mounted within the button housing 31. The second limiting rod extends through the second limiting hole 512 and is slidably connected thereto. The provision of the second limiting hole 512 and the second limiting rod ensures smooth and stable sliding of the button 51.

[0057] In practice, the user slides the slide button 3. When the second lock tongue 54 slides to face the lock opening 55, the second lock tongue spring releases its stored kinetic energy, pushing the second lock tongue 54, causing the second lock tongue 54 to slide into the lock opening 55. The second lock tongue 54 and the lock opening 55 are then locked together. The position of the slide button 3 and the traction box 2 is locked, and the traction box 2 is in a position to tighten the brake cable 21. When the user wants to release the lock, they simply press the button 51. The third inclined sliding surface 513 and the inclined sliding opening 541 slide relative to each other, causing the second lock tongue 54 to move out of the lock opening 55. The second lock tongue spring contracts, releasing the second lock tongue 54 and the lock opening 55.

[0058] Example 6: Figure 11 As shown, the reset compensation mechanism 6 includes a reset chamber 1 61, which is provided between the slide button 3 and the outer shell 1. An elastic component is provided in the reset chamber 1 61, which is a reset spring 1. One end of the reset spring 1 is fixedly connected to the slide button 3, and the other end of the reset spring 1 is fixedly connected to the outer shell 1. The provision of the reset spring 1 allows the slide button 3 and the traction box 2 to be fully reset.

[0059] In practice, when the user slides the slide button 3, the return spring 1 located between the slide button 3 and the outer housing 1 contracts. Subsequently, when the slide button 3 moves to a predetermined position, the locking assembly 5 locks the slide button 3. When the user unlocks the slide button 3, the return spring 1 releases its elastic potential energy and pushes the slide button 3. The return spring 1 pushes the slide button 3 to fully return to its original position. Since the slide button 3 is fully returned to its original position, the traction box 2 and the brake cable 21 are also fully returned to their original position.

[0060] Example 7, as Figure 11-12 As shown, the reset compensation mechanism 6 includes a second reset chamber 62, which is further defined between the traction box 2 and the outer shell 1. An elastic component is disposed within the second reset chamber 62. The elastic component is a second reset spring, one end of which is fixedly connected to the traction box 2, while the other end of the second reset spring is fixedly connected to the outer shell 1. The provision of the first reset spring allows the slider 3 and the traction box 2 to be fully reset.

[0061] In specific implementation, when the user slides the slide button 3, the slide button 3 drives the traction box 2 to move via the transmission assembly 4, causing the return spring 2 located between the traction box 2 and the outer shell 1 to contract. Subsequently, when the slide button 3 moves to a predetermined position, the locking assembly 5 locks the slide button 3. When the user unlocks the slide button 3, the return spring 2 releases its elastic potential energy, thereby pushing the traction box 2. The return spring 2 can push the traction box 2 to fully return to its original position. Since the traction box 2 and the brake cable 21 are fully returned to their original position, the slide button 3 is also fully returned to its original position.

[0062] Example eight, as Figure 11-12 As shown, to ensure the reinforcement effect, two sets of reset springs are provided: reset spring 1 and reset spring 2. One end of the reset spring 1 is fixedly connected to the slide button 3, and the other end of the reset spring 1 is fixedly connected to the outer shell 1. By providing the reset spring 1 and the reset spring 2, the traction box 2 and the brake cable 21 are completely reset.

[0063] Specifically, since two sets of reset springs installed in different positions are provided to reset the traction box 2 and the brake cable 21, the reset stability performance will be better. Even if one set of reset springs fails, the other set of reset springs can still perform the reset work normally, so the reset compensation mechanism will operate more stably.
