Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a luggage brake wheel mechanism. Background Technology

[0002] In many travel situations, suitcases have become an essential piece of travel equipment. Suitcases are usually composed of a body and wheels. The wheels make it very convenient to move the suitcase. However, in actual use, it is often necessary to lock the wheels to prevent the suitcase from sliding around.

[0003] In existing technology, the wheel locking function of a suitcase is usually achieved by a brake paddle fixed to the side of the wheel seat. When using it, you need to bend over to press and lift the brake paddle to lock and unlock the wheel. This is not only difficult to operate, but also makes your hands or shoes dirty. Therefore, a suitcase brake wheel mechanism is needed to make it easy for users to lock and unlock the wheels. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a luggage brake wheel mechanism.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A luggage brake wheel mechanism includes a brake box, a brake cable, brake pads, and a wheel. The brake box contains a brake drive block, a brake reset block, a positioning block, an unlock button, and a brake button. The brake reset block is connected to the brake box via a brake reset block connecting rod and can rotate vertically. The brake button is elongated and connected to the brake reset block at its bottom. Pressing the brake button causes the brake reset block to rotate downwards at its connection point, while simultaneously rotating the brake reset block upwards at its contact side with the brake drive block. The top of the brake reset block contacts the bottom of the brake drive block, causing the brake drive block to move upwards. The brake drive block has a positioning hole that matches the positioning block. When the brake drive block moves upwards to a specific height, the positioning hole is engaged with the positioning block. A positioning spring is located behind the positioning block, and the positioning block is positioned by a positioning protrusion. The unique shape design allows the brake transmission block to move upward, pushing the positioning block backward and compressing the positioning spring. After the positioning block aligns with the positioning hole, the positioning spring causes the positioning block to enter the positioning hole and fix the brake transmission block. The bottom of the unlock button contacts the positioning block. Through the cooperation of the unlocking slope of the positioning block and the unlocking slope of the unlock button, pressing the unlock button pushes the positioning block backward, leaving the positioning hole and releasing the brake transmission block. The brake transmission block is connected to the top of the brake cable, and the bottom of the brake cable is connected to the brake pad. The brake cable and brake pad move up and down with the brake transmission block. The inner side of the wheel has a wheel brake groove that matches the brake pad. When the brake transmission block is fixed by the positioning block, the brake pad is located in the wheel brake groove and locks the wheel seat. This achieves the easy locking and unlocking functions of locking the wheel by pressing the brake button to prevent rotation and unlocking the wheel by pressing the unlock button to allow rotation.

[0007] In one embodiment, the brake reset block includes a brake reset block connecting rod and a brake button connecting rod. The brake reset block connecting rod is a cylindrical rod passing through the middle of the brake reset block, and the brake button connecting rod is a cylindrical rod fixed to one side of the rear end of the brake reset block. The brake box has a brake reset block connecting rod hole located in the lower half of the brake box. The brake reset block connecting rod is connected to the brake reset block connecting rod hole. After connection, the brake reset block can be flipped inside the brake box. The bottom of the brake button has a brake button connecting rod hole, and the brake button connecting rod is connected to the brake button connecting rod hole. After connection, the brake button controls the displacement of the brake reset block.

[0008] In one embodiment, the brake box has a positioning block assembly position, which is a rectangular hole area in the upper half of the brake box. The positioning block is located in the positioning block assembly position and is rectangular in shape and its size is just right to be inserted into the rectangular hole of the positioning block assembly position. The positioning block has a positioning protrusion and a positioning block unlocking slope. The positioning block unlocking slope occupies half of the positioning block, and the positioning protrusion is located in front of the other half of the positioning block. The positioning protrusion has a slope below and a flat surface above. The bottom of the unlocking button has an unlocking button slope that matches the positioning block unlocking slope. The unlocking button slope contacts the positioning block unlocking slope. The slope design can convert vertical thrust into backward thrust to move the positioning block backward, realizing the function of the positioning block entering the positioning hole to fix the brake transmission block and the unlocking button pushing the positioning block.

[0009] In one embodiment, the bottom of the brake transmission block is provided with a brake cable mounting hole, the shape of which matches the brake cable core. The top end of the brake cable is located in the brake cable mounting hole and is fixedly connected to the brake transmission block. The brake transmission block drives the brake cable to move up and down.

[0010] The top of the brake transmission block is equipped with a brake transmission block spring that contacts the brake button. When the brake button is pressed, the brake transmission block spring accumulates elastic force. When the unlock button is pressed to release the brake transmission block, the elastic force is quickly released, causing the brake transmission block to move downward and the brake button to pop up. This facilitates user operation and avoids incorrect locking caused by bumps.

[0011] In one embodiment, the brake cable consists of a brake cable core and a brake cable tube. The brake cable core moves up and down inside the brake cable tube. The top of the brake cable core is fixed in the brake cable mounting hole. The top of the brake cable core moves up and down with the brake transmission block. The brake pad is fixed to the bottom of the brake cable core. A brake pad spring is provided between the brake pad and the brake cable tube. The brake pad moves up and down with the brake cable core. The brake pad spring is used to push the brake pad out of the wheel brake groove when unlocking, so as to prevent the brake pad from still jamming the wheel after unlocking.

[0012] In one embodiment, the brake pads move up and down with the brake cable, and the brake cable moves up and down with the brake transmission block. When the brake button is pressed down, it causes the brake reset block to flip. The flipped brake reset block pushes the brake transmission block upward. The positioning block enters the positioning hole to fix the brake transmission block. When the unlock button is pressed down, it pushes the positioning block backward to release the brake transmission block. The brake pads move upward and enter the wheel brake groove to lock the wheel. The brake pads move downward and leave the wheel brake groove to unlock the wheel, thus realizing the function of locking and unlocking the wheel by pressing the button.

[0013] In one embodiment, the bottom of the suitcase is provided with a wheel seat, a wheel fork, a wheel, a wheel fork fixing pin, and a wheel fixing pin. The wheel seat is fixed to the bottom of the suitcase, the wheel fork is connected to the wheel seat through the wheel fork fixing pin, and the wheel is connected to the wheel fork through the wheel fixing pin. The brake cable passes through the wheel seat and is fixed to the wheel fork. A shock-absorbing spring is provided on the outside of the wheel fork fixing pin. The shock-absorbing spring is located between the wheel fork and the wheel seat. When the wheel encounters an uneven road surface, the shock-absorbing spring is compressed and deformed, converting the impact kinetic energy into elastic potential energy, which greatly reduces the vibration transmitted to the suitcase body. This effectively protects the items inside the suitcase from bumps and damage, while also making the wheel closer to the ground, making dragging more stable and smooth, and extending the service life of the wheel and suitcase structure.

[0014] In one embodiment, the brake cable passes through the wheel fork fixing pin and connects to the brake pad. The wheel fork has a brake pad movable position, which is a cylindrical tunnel inside the wheel fork. The brake pad moves up and down in the brake pad movable position. When the brake button is pressed, the brake pad is at the upper end of the brake pad movable position. At this time, the brake pad is engaged in the wheel brake groove to lock the wheel. When the brake button is not pressed, the brake pad is at the lower end of the brake pad movable position. At this time, the brake pad is away from the wheel brake groove, and the wheel can rotate freely.

[0015] In one embodiment, a brake box cover is provided at the front of the brake box. The brake box cover is a rectangular piece and is fixed to the front of the brake box with screws to protect and fix the internal parts. A brake wheel mechanism cover is provided above the brake box, and the brake wheel mechanism cover is exposed on the upper surface of the luggage compartment. The brake wheel mechanism is located below the luggage compartment handle. The brake wheel mechanism located below the luggage compartment handle can reduce accidental operation of the unlock button and brake button during use, and protect the unlock button and brake button when the handle is retracted. The unlock button and brake button pass through the brake wheel mechanism cover, and the user can easily press the unlock button and brake button. The brake cable is located in the internal space on the side of the luggage compartment. The brake cable passes through the internal space of the luggage compartment and is directly connected to the luggage compartment wheel. A brake cable fixing seat is provided at the bottom of the brake cable. The brake cable core can pass through the brake pad and wheel fork. The brake cable fixing seat cannot pass through the brake pad. The brake cable and brake pad are assembled to the wheel fork through the brake cable fixing seat.

[0016] In one embodiment, a brake wheel mechanism cover is provided above the brake box. The brake wheel mechanism cover is located on one side of the suitcase, opposite to the suitcase handle. The unlock button and brake button pass through the brake wheel mechanism cover. The brake wheel mechanism can be installed not only below the suitcase handle but also on any side of the suitcase. The brake wheel mechanism cover is located on the upper surface of the suitcase. When using the brake wheel mechanism, it is not necessary to pull up the suitcase handle, making the operation more convenient and faster.

[0017] The beneficial effects of this utility model are:

[0034] Please refer to Embodiment 1 of this utility model. Figure 1-7 :

[0035] A luggage brake wheel mechanism includes a brake box 1, a brake cable 2, a brake pad 3, and a wheel 4. The brake box 1 contains a brake transmission block 5, a brake reset block 6, a positioning block 10, an unlock button 7, and a brake button 8. The bottom of the brake button 8 is connected to the brake reset block 6, and the top of the brake reset block 6 contacts the bottom of the brake transmission block 5. The brake transmission block 5 has a positioning hole 9 that matches the positioning block 10. A positioning spring 11 is provided behind the positioning block 10. The bottom of the unlock button 7 contacts the positioning block 10. The brake transmission block 5 is connected to the top of the brake cable 2, and the bottom of the brake cable 2 is connected to the brake pad 3. The inner side of the wheel 4 has a wheel brake groove 12 that matches the brake pad 3.

[0036] By adopting the above technical solution, a brake reset block 6 that can flip up and down the brake box 1 is used. Pressing the brake button 8 causes the brake reset block 6 to rotate downward at its connection point, and the side of the brake reset block 6 that contacts the brake transmission block 5 to rotate upward, lifting the brake transmission block 5 upward. When the brake transmission block 5 moves upward to a specific height, the positioning block 10 enters the positioning hole 9. The positioning block 10, which does not move when pressed down, moves backward when lifted, and has a positioning spring 11 on its back, fixes the brake transmission block 5, causing the brake transmission block 5 to lift the brake pad 3 connected to the brake cable 2, allowing the brake pad 3 to enter the wheel brake groove. 12 locks wheel 4, enabling the function of locking wheel 4 when the brake button 8 is pressed. Then, when the unlock button 7 is pressed, the positioning block 10 is pushed back away from the positioning hole 9 to release the brake transmission block 5 through the cooperation of the positioning block unlocking slope 19 and the unlock button slope 20. The brake transmission block 5 falls down due to gravity, and the brake button 8 is lifted by the brake transmission block spring 25, which drives the brake pad 3 to fall and disengage from the wheel brake groove 12. This achieves the easy locking and unlocking function of locking wheel 4 by pressing the brake button 8 to prevent rotation and unlocking wheel 4 by pressing the unlock button 7 to allow it to rotate.

[0037] Preferably, the brake reset block 6 is provided with a brake reset block connecting rod 13 and a brake button connecting rod 14, the brake box 1 is provided with a brake reset block connecting rod hole 15, the brake reset block connecting rod 13 is connected to the brake reset block connecting rod hole 15, the bottom of the brake button 8 is provided with a brake button connecting rod hole 16, and the brake button connecting rod 14 is connected to the brake button connecting rod hole 16.

[0042] By adopting the above technical solution, the movement of the button on the top of the suitcase can be transmitted to the brake pad 3 of the wheel 4 at the bottom of the suitcase using the thin brake line 2. The wheel 4 can be easily locked and unlocked without the user having to squat down, which is convenient for the user. In addition, the brake line 2 does not take up space and is easy to assemble and store.

[0043] The brake transmission block spring 25, which is in contact with the top and bottom surface of the brake button 8, accumulates elastic force when the brake button 8 is pressed. When the unlock button 7 is pressed to release the brake transmission block 5, the elastic force is quickly released, causing the brake transmission block 5 to move downward and the brake button 8 to pop up. This facilitates user operation and avoids incorrect locking caused by bumps.

[0044] Preferably, the brake cable 2 is composed of a brake cable core 22 and a brake cable tube 23. The brake cable core 22 moves up and down inside the brake cable tube 23.

[0049] By adopting the above technical solution, a shock-absorbing spring is added between the wheel 4 and the suitcase to buffer the impact of road bumps. When the wheel 4 encounters an uneven road surface, the shock-absorbing spring 35 is compressed and deformed to convert the impact kinetic energy into elastic potential energy, which greatly reduces the vibration transmitted to the suitcase body, thereby effectively protecting the items inside the suitcase from bumps and damage. At the same time, it makes the wheel 4 closer to the ground, drags more smoothly, and extends the service life of the wheel 4 and the suitcase structure.

[0050] Preferably, the brake line 2 passes through the wheel fork fixing pin 29 and is connected to the brake pad 3. The wheel fork 27 is provided with a brake pad movable position 31. The brake pad 3 moves up and down in the brake pad movable position 31. When the brake pad 3 is at the upper end of the brake pad movable position 31, the brake pad 3 is engaged in the wheel brake groove 12 to lock the wheel 4. When the brake pad 3 is at the lower end of the brake pad movable position 31, the brake pad 3 leaves the wheel brake groove 12 to unlock the wheel 4.

[0051] By adopting the above technical solution, the brake line 2, which passes through the wheel fork fixing pin 29 and connects to the brake pad 3, controls the brake pad 3 to move up and down within the brake pad movable position 31. When the brake button 8 is pressed, the brake pad 3 is at the upper end of the brake pad movable position 31. At this time, the brake pad 3 is engaged in the wheel brake groove 12 to lock the wheel 4. When the brake button 8 is not pressed, the brake pad 3 is at the lower end of the brake pad movable position 31. At this time, the brake pad 3 leaves the wheel brake groove 12, and the wheel 4 can rotate freely.

[0052] Preferably, the brake box 1 is provided with a brake box cover 32 at the front, and a brake wheel mechanism cover 33 is provided on the top of the brake box 1.
