Description

Technical Field

[0001] This invention relates to a quick-disassembly structure and a stair climber. Background Technology

[0002] A stair climber is a commonly used auxiliary material handling device. As a material handling device, it can effectively solve the problem of moving goods up and down stairs. A stair climber generally includes a carrying rack, a walking mechanism, and a drive module. The drive module generally includes a motor and a reducer. The motor and reducer drive the walking mechanism forward, thereby realizing the action of climbing stairs.

[0003] However, for simply moving goods, climbing stairs is only a small part of the scenario. More often, it is necessary to realize the simple function of pushing a cart on flat ground. Because the stair climber is equipped with a reducer and motor, its weight is relatively large, which makes it more difficult to push the cart on flat ground. Summary of the Invention

[0055] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0056] First, it should be noted that the directions such as top, bottom, upward, and downward mentioned in this article are defined relative to the directions in the various accompanying figures. They are relative concepts and therefore can change depending on their different positions and practical applications. Therefore, these or other directions should not be interpreted as restrictive terms.

[0057] It should be noted that the term "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude the plural.

[0058] Furthermore, it should be noted that any single technical feature described or implied in the embodiments herein, or any single technical feature shown or implied in the accompanying drawings, can still be combined among these technical features (or their equivalents) to obtain other embodiments of this application not directly mentioned herein.

[0059] It should also be understood that while the terms "first," "second," etc., are used in this document to describe various types of information, this information should not be limited to these terms, which are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0060] It should be noted that in different figures, the same reference numerals denote the same or substantially the same components.

[0061] This application provides a quick disassembly structure; see [link to relevant documentation]. Figure 1 , Figure 3 , Figure 5 It includes: a first mounting part 2, a second mounting part 3, and a locking component 5 for locking the first mounting part 2 and the second mounting part 3. The first mounting part 2 is disposed on the load rack 1 of the stair climber 18, the second mounting part 3 is detachably connected to the first mounting part 2, a drive mechanism 4 is disposed on the second mounting part 3, and the locking component 5 is used to lock the first mounting part 2 and the second mounting part 3. The second mounting part is used to mount the drive mechanism 4, and the drive mechanism 4 includes: a first motor 41 disposed on the second mounting part 3 and a reducer 42 disposed on the second mounting part 3.

[0062] See Figure 3 , Figure 7 and Figure 10 The locking component 5 includes: a hook 51 disposed on the second mounting part 3, a rotating handle 52 pivotally connected to the first mounting part 2, and a locking block 53 disposed on the locking handle.

[0063] The handle 52 can rotate relative to the first mounting part 2 and can be in a locked or unlocked position.

[0064] When the handle 52 is in the locked position, the locking block 53 locks with the hook 51, and the locking block 53 and the hook 51 cooperate to lock the first mounting part 2 and the second mounting part 3; when the handle 52 is in the unlocked position, the locking block 53 and the hook 51 unlock, and the first mounting part 2 and the second mounting part 3 can move relative to each other to be disassembled.

[0065] Based on the above structure, this application installs the drive mechanism 4 for driving the stair climber 18 to the second mounting part 3, and the carrier 1 on the stair climber 18 and the first mounting part 2 installed on the carrier 1 are detachably connected to the second mounting part 3. When the stair climber 18 needs to use electric drive, the second mounting part 3 can be installed on the first mounting part 2 so that the drive mechanism 4 can be installed on the first mounting part 2, thereby realizing the electric drive of the stair climber 18. When the electric drive is not needed, the second mounting part 3 can be removed from the first mounting part 2 so that the drive mechanism 4 can be removed from the first mounting part 2.

[0066] Based on this, users can easily assemble and disassemble the drive mechanism 4 by a single person. In this application, the main drive mechanism 4 of the stair climber 18 is installed as a quick-disassembly unit on the second mounting part 3 and can be quickly removed from the first mounting part 2. This allows the stair climber 18 to remove the second mounting part 3 and use it as a handcart under normal conditions to reduce the overall weight. When climbing stairs is required, the second mounting part 3 can be installed again to realize the electric drive of the stair climber 18.

[0067] When the second mounting part 3 needs to be installed onto the first mounting part 2, the second mounting part 3 is placed over the first mounting part 2, and the rotating handle 52 is rotated from the unlocked position to the locked position, so that the locking block 53 locks onto the latch 51, thereby locking the first mounting part 2 and the second mounting part 3 together. When the second mounting part 3 needs to be removed from the first mounting part 2, the rotating handle 52 is rotated from the locked position to the unlocked position, so that the locking block 53 disengages from the latch 51, thereby unlocking the first mounting part 2 and the second mounting part 3, and then the second mounting part 3 is removed from the first mounting part 2.

[0068] Specifically, see Figure 5 The first mounting part 2 and the second mounting part 3 are both frames, and the first mounting part 2 can be adapted to fit and cover the second mounting part 3. It is understood that in other embodiments, the first mounting part 2 and the second mounting part 3 are not limited to the above-described form, as long as their functions can be achieved.

[0069] Further, see Figure 6 and Figure 15 The first mounting part 2 has a first side 21 opposite to the second mounting part 3 and a second side 22 arranged opposite to the first side. The first side 21 is provided with a relief cavity 211 that can accommodate the hook 51, so that when the first mounting part 2 and the second mounting part 3 are closed, the hook 51 can enter the relief cavity 211, so that the first mounting part 2 and the second mounting part 3 can fit together as closely as possible after assembly, preventing foreign objects from entering between the first mounting part 2 and the second mounting part 3.

[0070] Furthermore, the hook 51 is provided with a slot 513, and when the rotating handle 52 is in the locked position, the locking block 53 can be locked in the slot 513.

[0071] Further, see Figure 3 , Figure 8 , Figure 10 as well as Figure 11 The latch 51 includes a first baffle 511 and a second baffle 512. The first baffle 511 is fixedly connected to the second mounting part 3. The second baffle 512 is fixedly connected to the first baffle 511. The first baffle 511 and the second baffle 512 clamp together to form a slot 513 for locking with the locking block 53. When it is necessary to lock the first mounting part 2 and the second mounting part 3, the second baffle 512 is inserted into the relief cavity 211. Then, by rotating the handle 52 relative to the first mounting part 2, the locking block 53 is placed in the slot 513, thereby limiting the second baffle 512 in the relief cavity 211 and simultaneously locking the first mounting part 2 and the second mounting part 3.

[0072] Specifically, see Figure 10 The cross-section formed by the connection of the first baffle 511 and the second baffle 512 is T-shaped.

[0073] See Figure 3 The shape of the clearance cavity 211 is adapted to the shape of the second baffle 512, so that when the second baffle 512 is inserted into the clearance cavity 211, the first mounting part 2 and the second mounting part 3 are exactly aligned, thereby playing a positioning role. In addition, it also prevents the second baffle 512 from moving in the clearance cavity 211 when it is locked by the locking block 53, which would lead to unstable installation of the first mounting part 2 and the second mounting part 3.

[0074] In one possible embodiment of the rotating handle 52, see [reference needed]. Figure 3 , Figure 9 as well as Figure 10The rotating handle 52 includes a first handle body 521 and a second handle body 522. The first mounting portion 2 has a through groove 23 connecting the first side surface 21 and the second side surface 22. The first end of the first handle body 521 is pivotally connected to the first side surface 21 via a first pivot 15. The second end of the first handle body 521 passes through the through groove 23 and is fixedly connected to the first end of the second handle body 522. A locking block 53 is disposed on the first handle body 521. The first handle body 521 can move within the through groove 23. When the first mounting portion 2 is closed onto the first side surface 21, the user can grip the second handle body 522 on the second side surface 22 and swing it, allowing the first handle body 521 to rotate around the first pivot 15, thereby switching the first handle body 521 between a locked position and an unlocked position.

[0075] Furthermore, the locking block 53 serves as the first limiting shaft. The rotating handle 52 is rotatably connected to the first mounting part 2 via the first pivot 15. The first limiting shaft is fixedly connected to the rotating handle 52, and the first limiting shaft is eccentrically positioned relative to the first pivot 15. When the rotating handle 52 is in the locked position, the first limiting shaft is engaged within the slot 513. The first pivot 15 is parallel to the first limiting shaft, meaning that when the first handle 521 rotates around the first pivot 15, the first limiting shaft can rotate around the first pivot 15 as its center of rotation.

[0076] Furthermore, the inner wall of the slot 513 includes a first limiting wall facing the second mounting part 3 and a second limiting wall 5132 adjacent to the first limiting wall 5131. When the rotating handle 52 is in the locked position, the locking block 53 abuts against the first limiting wall 5131 and the second limiting wall 5132 respectively. Specifically, the side wall of the first baffle 511 facing the first pivot 15 is the second limiting wall 5132, and the side wall of the second baffle 512 facing the second mounting part 3 is the first limiting wall 5131.

[0077] by Figure 3 From a baseline perspective, the user can switch the first handle 521 from the locked position to the unlocked position by rotating it clockwise. This causes the first limiting shaft to rotate clockwise around the first pivot 15 and move away from the clearance cavity 211, allowing the second baffle 512 to be inserted into the clearance cavity 211. Then, the user can switch the first handle 521 from the unlocked position to the locked position by rotating it counterclockwise. This causes the first limiting shaft to rotate counterclockwise around the first pivot 15 and move into the clearance cavity 211. At the same time, the first limiting shaft can be engaged in the slot 513 to lock the second baffle 512 in the clearance cavity 211.

[0078] In addition, when the first limiting shaft is in the locked position, the first limiting shaft abuts against the first limiting wall 5131 of the second baffle 512 to hold the second baffle 512 against the relief cavity 211, thereby limiting the movement of the second mounting part 3.

[0079] Specifically, see Figure 9 There are two first handle bodies 521 and two second handle bodies 522, and the two first handle bodies 521 and the two second handle bodies 522 are symmetrically distributed on opposite sides of the first mounting part 2, and the first limiting shaft is connected between the two first handle bodies 521 respectively.

[0080] Furthermore, when the handle is in the locked position, the force exerted by the first limiting wall on the first limiting shaft points between the center line of the first pivot and the second limiting wall. See details... Figure 11 , Figure 12 and Figure 14 When the handle 52 is in the locked position, the plane perpendicular to the first limiting wall and the center line of the first pivot 15 is the first plane 26, and the plane perpendicular to the first limiting wall and the center line of the first limiting axis is the second plane 27. The second plane 27 is located between the first plane 26 and the bottom surface of the slot 513, that is, with Figure 3 From a baseline perspective, when the first limiting shaft is in the locked position, the force of the second mounting part 3 pulling out from the first mounting part 2 is converted into the force of the second baffle 512 acting on the first limiting shaft. When the second plane 27 is located between the first plane 26 and the bottom surface of the slot 513, the force of the second baffle 512 acting on the first limiting shaft can only drive the first limiting shaft to rotate counterclockwise around the first pivot 15, so as to realize the self-locking function of the first mounting part 2 and the second mounting part 3.

[0081] See Figure 11 , Figure 13 and Figure 14 When the handle 52 is in the locked position, the distance between the center line of the first pivot 15 and the second limiting wall is L1, and the distance between the center line of the first pivot 15 and the first limiting wall is L2, where L1 < L2. That is, with... Figure 3 From a baseline perspective, when the first limiting shaft is in the locked position, the force exerted by the second mounting part 3 against the first mounting part 2 is converted into a force exerted by the second baffle 512 on the first limiting shaft. However, when the second plane 27 is located between the first plane 26 and the bottom surface of the slot 513, the force exerted by the second baffle 512 on the first limiting shaft can only drive the first limiting shaft to rotate counterclockwise around the first pivot 15. See also... Figure 13As mentioned above, the second baffle 512 is adapted to the relief cavity 211 so that the second baffle 512 cannot move in the relief cavity 211 when locked. At the same time, L1 < L2, so that the first limiting shaft cannot rotate counterclockwise past the first baffle 511, and so that the first limiting shaft can only abut against the first baffle 511 when it rotates counterclockwise to the maximum angle. This realizes the self-locking function of the first limiting shaft, the first baffle 511, and the second baffle 512, thereby realizing the self-locking function of the first mounting part 2 and the second mounting part 3.

[0082] Specifically, when the rotating handle 52 is in the locked position, the plane containing the center line of the first pivot 15 and the center line of the first limit axis is the third plane 28, and the angle between the first plane 26 and the third plane 28 is β, wherein 3°≤β≤10°, preferably 5.27°.

[0083] Further, see Figure 3 and Figure 4 When the locking block 53 is in the locked position, the second handle 522 abuts against or approaches the second side surface 22. That is, when the second handle 522 is in contact with the second side surface 22, and the first limiting shaft is in the locked position, the second plane 27 is located between the first plane 26 and the bottom surface of the slot 513, so that the user can operate the first mounting part 2 and the second mounting part 3 to lock by operating the second handle 522 to contact the first side surface 21. Furthermore, when the rotating handle 52 is in the locked position, the second handle 522 and the first side surface 21... When the two parts are close together, the force of the second mounting part 3 pulling out from the first mounting part 2 will be converted into the force of the second baffle 512 acting on the first limiting shaft. When the rotating handle is in the locked position, the force of the first limiting wall applied to the first limiting shaft is directed between the center line of the first pivot and the second limiting wall. In this way, the hook 51 will drive the second handle 522 of the rotating handle 52 to press against the second side 22, that is, the rotating handle 52 can no longer rotate. At the same time, the rotating handle 52 will further drive the locking block 53 to lock the hook.

[0084] Specifically, the distance between the second side 22 and the second handle 522 is between 1 and 5 mm.

[0085] In one possible implementation, the first mounting portion 2 is provided with a first protrusion 6, and the second mounting portion 3 is provided with a first recess 7 that matches the first protrusion 6. The arrangement of the first protrusion 6 and the first recess 7 enables the positioning of the first mounting portion 2 and the second mounting portion 3. Alternatively, the first mounting portion 2 is provided with a second recess 8, and the second mounting portion 3 is provided with a second protrusion 9 that matches the second recess 8. The arrangement of the second protrusion 9 and the second recess 8 enables the positioning of the first mounting portion 2 and the second mounting portion 3.

[0086] Specifically, in this embodiment, the first mounting part 2 is provided with a first protrusion 6, and the second mounting part 3 is provided with a first recess 7 that is adapted to the first protrusion 6. The first protrusion 6 and the first recess 7 can realize the positioning of the first mounting part 2 and the second mounting part 3, and the first end of the first handle 521 is rotatably connected to the first protrusion 6.

[0087] Furthermore, the first mounting part 2 and the second mounting part 3 are respectively made of aluminum alloy.

[0088] Further, see Figure 18 The embodiment of the invention further includes a cover 10. The cover 10 is detachably disposed on the second side surface 22. The cover 10 and the second side surface 22 together enclose a receiving cavity. The locking component 5 is housed within the receiving cavity.

[0089] Specifically, see Figure 18 One end of the cover 10 is pivotally connected to the second side surface 22 via a second pivot 101. The other end of the cover 10 is provided with a buckle 102, and the second side surface 22 is provided with a corresponding locking hole 221. The cover 10 can be locked onto the second side surface 22 by engaging the buckle 102 and the locking hole 221. The user can operate the second handle by opening the cover 10, or close the cover 10 to protect the second handle from accidental operation.

[0090] In one possible embodiment, see Figure 3 and Figure 4 There are two sets of locking components 5, and the second handles 522 of both locking components 5 are housed in the receiving cavity formed between the cover 10 and the second side 22. The two sets of locking components 5 are arranged symmetrically. When the locking blocks 53 of the two locking components 5 are in the locked position, the second handles 522 of the two locking components 5 are positioned facing each other. That is, the two locking components 5 lock the second mounting part 3 onto the first mounting part 2 from two different directions.

[0096] Work process:

[0097] When the second mounting part 3 needs to be installed onto the first mounting part 2, the first limiting shaft is in the locked position. By rotating the first handle 521 clockwise, the first handle 521 is switched from the locked position to the unlocked position, thereby causing the first limiting shaft to rotate clockwise around the first pivot 15 and move away from the clearance cavity 211. The second mounting part 3 is then placed on the first mounting part 2 so that the second baffle 512 can be inserted into the clearance cavity 211. Then, the second baffle 512 is inserted into the clearance cavity 211. Then, by rotating the first handle 521 counterclockwise, the first handle 521 is switched from the unlocked position to the locked position, thereby causing the first limiting shaft to rotate counterclockwise around the first pivot 15 and move into the clearance cavity 211, thereby locking the first mounting part 2 and the second mounting part 3 together.

[0098] When it is necessary to detach the second mounting part 3 from the first mounting part 2, the first limiting shaft is in the locked position. By rotating the first handle 521 clockwise, the first handle 521 is switched from the locked position to the unlocked position, thereby causing the first limiting shaft to rotate clockwise around the first pivot 15 and move away from the clearance cavity 211. Then, the second baffle 512 is pulled out of the clearance cavity 211 to unlock the first mounting part 2 and the second mounting part 3. Then, the second mounting part 3 is detached from the first mounting part 2.

[0099] In summary, this invention achieves a detachable connection between the first mounting part 2 and the second mounting part 3 by setting the drive mechanism 4 on the second mounting part 3 and the first mounting part 2 on the carrier 11, and then by using the first handle 521, the second handle 522, the first limiting shaft, the first baffle 511, and the second baffle 512. On the one hand, this allows the stair climber 18 to remove the second mounting part 3 and use it as a handcart under normal conditions to reduce the overall weight. When climbing stairs is required, the second mounting part 3 can be reinstalled to achieve electric drive of the stair climber 18. On the other hand, this method of disassembling the first mounting part 2 and the second mounting part 3 is efficient and fast, reducing disassembly and assembly time. Furthermore, when the first limiting shaft is in the locked position, the second plane 27 is located between the first plane 26 and the bottom surface of the slot 513, so that the first mounting part 2 and the second mounting part 3 can achieve self-locking after the first limiting shaft is in the locked position.

[0100] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
