Detailed Description

Example 1:

in the present embodiment, referring to fig. 1 to 4, there is provided a folder comprising a handle 1, a lower end cap 2 and an upper end cap 3 for connecting a stand pipe 100;

the upper end cover 3 and the handle 1 are respectively hinged with the lower end cover 2, wherein the upper end cover 3 and the handle 1 can be connected through a lock catch assembly;

the locking assembly comprises a top column 401, a spring 402 and a handle hook 403;

the fore-set 401 is set up on handle 1, the extending direction of fore-set 401 is the same with the extending direction of handle 1, spring 402 and handle couple 403 overlap respectively and establish on fore-set 401, wherein, the both ends of fore-set 401 are head end A and tail end B respectively (see fig. 3), the articulated department of lower end cover 2 and handle 1 is kept away from to head end A, tail end B is close the articulated department of lower end cover 2 and handle 1, spring 402 is located between head end A and handle couple 403, handle couple 403 is located between spring 402 and tail end B.

Wherein, the upper end cover 3 and the lower end cover 2 have a separation state and a covering state; when the upper end cap 3 and the lower end cap 2 are in a separated state, the necessary conditions are as follows: after the handle 1 is separated from the upper end cover 3, the upper end cover 3 is turned over relative to the lower end cover 2 to be in a separated state; when the upper end cover 3 and the lower end cover 2 are in a closed state, two situations can occur: the first situation is as follows: only the upper end cover 3 is covered on the lower end cover 2, and the handle 1 and the upper end cover 3 are separated from each other, and the second case is that: the upper end cover 3 is covered on the lower end cover 2, and the handle 1 is connected with the upper end cover 3.

The direction defined by the composition of the upper end cap 3 and the lower end cap 2 when the upper end cap 3 and the lower end cap 2 are in a closed state is defined as an axial direction, wherein the direction from the upper end cap 3 to the lower end cap 2 is defined as an axial downward direction, and the direction from the lower end cap 2 to the upper end cap 3 is defined as an axial upward direction; meanwhile, a plane direction perpendicular to the axial direction is defined as a radial direction, and it should be understood that the defined axial direction, radial direction, upward and downward are merely for convenience of description and should not be associated with specific features of any component.

The hinge joint of the upper end cover 3 and the lower end cover 2 is a first hinge joint W (see fig. 4), the hinge joint of the lower end cover 2 and the handle 1 is a second hinge joint X (see fig. 4), the first hinge joint W and the second hinge joint X are respectively isolated from each other in the radial direction of the lower end cover 2, and the axial line of the first hinge joint W is parallel to the axial line of the second hinge joint X.

The specific solution of hinging of the upper end cover 3 and the lower end cover 2 can be realized by common knowledge known to those skilled in the art; for example: two lug parts 301 (see fig. 3) may be provided on the upper end cover 3, the two lug parts 301 are respectively provided with a hinge through hole, the two hinge through holes are coaxially arranged, the lower end cover 2 may be provided with a cylindrical protrusion 201, the protrusion 201 is provided with a force through hole, the two hinge through holes and the force through hole are coaxial and communicated, the force through hole may be arranged between the two hinge through holes, and the upper end cover 3 and the lower end cover 2 may be hinged by penetrating the two hinge through holes and the force through hole through a rod-like member 01 (e.g., a bolt, a shaft lever, a rod, a sleeve, etc.).

Similarly, the specific scheme of the hinge joint of the handle 1 and the lower end cap 2 may adopt a scheme similar to the aforementioned 'hinge joint of the upper end cap 3 and the lower end cap 2', and the remote mode is the same as or similar to the actual setting mode, and is not described again here.

The lock catch component is a combined functional component combination which is provided with a first lock catch part and a second lock catch part, and at least the first lock catch part and the second lock catch part are mutually connected and separated.

In this embodiment, the handle hook 403 is the aforementioned second locking portion or a main component of the second locking portion, the handle hook 403 can hook the aforementioned first locking portion, and the first locking portion can be implemented by using common knowledge known to those skilled in the art; for example: the first locking part can be a hole wall of an opening arranged at the upper end cover 3, and the handle hook 403 can hook the hole wall of the opening; or the first locking part may be a screw provided at the upper end cap 3, and the handle hook 403 may hook a head of the screw.

In this embodiment, the first locking portion preferably adopts a hook 404 (see fig. 2 and 3), and the hook 404 is provided with at least one through hole; the hook 404 is disposed at the upper end cover 3 through at least one first hook screw 408, wherein any one of the first hook screws 408 can penetrate one of the through holes; the hook 404 and the handle hook 403 may be hooked to each other.

The hook 404 serves as a first locking portion, and one of the purposes thereof is to enhance the strength of the locking member. In the prior art (an automatic quick lock folder for a scooter, application No. 201922391673.5), the feature of a fixed block (i.e., the hook 404 in this embodiment) is also used. In other prior arts, the first locking portion is usually disposed at an opening of the first end cap (corresponding to the upper end cap 3 in this embodiment), and the second locking portion can hook the inner wall of the first end cap at the opening; alternatively, in other prior arts, the first locking portion is usually a screw provided on the first end cap, and the second locking portion can hook the head of the screw. In the prior art that does not use the hook 404 (fixing block), the strength of the locking member is limited by the strength of the first end cap, or by the area of the head of the screw, and at the same time, by the thickness of the second locking portion (usually, the clip spring in a bent state), and in the prior art that does not use the hook 404 (fixing block), when the second locking portion hooks the first locking portion, if the 'tensile force' between the first locking portion and the second locking portion is too large, the first locking portion and/or the second locking portion may be deformed. In contrast, in the prior art in which the hook 404 (fixed block) is employed, the hook 404 itself is manufactured to conform to a predetermined width and thickness, wherein the predetermined thickness enhances the strength of the first locking portion (the hook 404 itself), and the predetermined width enhances the contact area between the first locking portion (the hook 404 itself) and the second locking portion (the snap spring in the prior art), thereby reducing the probability of deformation of the second locking portion. Therefore, in the present embodiment, the hook 404 can be used to better enhance the strength of the locking member.

The handle hook 403, the spring 402 and the top pillar 401 in this embodiment may constitute a kinematic pair, specifically, when the top pillar 401 is actually limited on the handle 1 (see fig. 2), two ends of the top pillar 401 form a joint with respect to the handle 1, at this time, the top pillar 401 located between the two ends of the top pillar 401 is in a sliding rod shape, and the spring 402 and the handle hook 403 are respectively sleeved on the sliding rod-shaped top pillar 401. In actual use, the handle hook 403 can be pulled by external force, and the handle hook 403 moves from the original position to the target position, so that the handle hook 403 can press the spring 402, and the spring 402 is transformed from the relaxed state to the compressed state, whereas when the handle hook 403 loses external force, the compressed spring 402 is transformed from the compressed state to the relaxed state, and the spring 402 can drive the handle hook 403 to return to the original position from the target position.

In the prior art (an automatic quick locking folder for a scooter, application No. 201922391673.5), when a spring (corresponding to a spring 402 in the present embodiment) and a hook (corresponding to a handle hook 403 in the present embodiment) are actually assembled to a wrench (corresponding to a handle 1 in the present embodiment), the spring cannot be directly positioned or fixed with respect to the hook, and the spring cannot be directly positioned or fixed with respect to the wrench, so that it is difficult to actually assemble the spring to the wrench.

In this embodiment, in the process that the spring 402 is actually disposed on the handle 1, the spring 402 and the handle hook 403 may be firstly sleeved on the pillar 401, and then the pillar 401 is disposed on the handle hook 403, so that the spring 402 is directly positioned or fixed with respect to the handle 1 through the pillar 401, and the spring 402 in this embodiment is easily assembled on the handle 1.

Therefore, the folder in the embodiment solves the technical problem that the spring and the hook in the prior art are difficult to assemble relative to the wrench respectively.

Further, in the above-described solution, how to set the top post 401 on the handle 1 becomes a technical problem to be solved.

In this embodiment, referring to fig. 1 to 5, a preferable scheme is proposed, which specifically includes:

the latch assembly further includes a top post support rod 405;

the top post strut 405 may be hinged to the handle 1;

the handle 1 has a support 101, wherein a space is left between the top pillar brace 405 and the support 101;

the head end a of the top pillar 401 may be connected to the top pillar support rod 405 and the tail end B of the top pillar 401 may be connected to the support portion 101.

When the support post 405 is actually disposed on the handle 1, the axis of the support post 405 is parallel to the plane of the support portion 101, and the axis of the support post 405 is not coplanar with the plane of the support portion 101.

The support 101 may be provided to the handle 1 in a manner of being integrally formed with the handle 1, or the support 101 may be provided as a separate member and the support 101 may be attached to the handle 1. In the present embodiment, it is preferable that the support portion 101 is formed integrally with the handle 1 (see fig. 5 or fig. 6), which can reduce the manufacturing process and the composition process of the handle 1 and the support portion 101, thereby contributing to reduction of the production cost.

The top pillar 401 is arranged on the handle 1 with the top pillar support rod 405 and the support part 101, so that the three (the top pillar 40, the top pillar support rod 405 and the support part 101) form an I-shaped structure, wherein the head end A of the top pillar 401 can be connected to the top pillar support rod 405, and the tail end B of the top pillar 401 can be connected to the support part 101; the connection of the top pillar 401 to the top pillar brace 405 and the support 101, respectively, may be made using common knowledge known to those skilled in the art, such as: the head end a of the top pillar 401 and the top pillar support rod 405 can be connected in a clamping manner, that is, a first clamping groove is formed in the top pillar 401, a second clamping groove is formed in the top pillar support rod 405, and the first clamping groove and the second clamping groove are clamped with each other; for another example: the tail end B of the top pillar 401 and the supporting portion 101 can be connected by two nuts, that is, a through hole is formed in the supporting portion 101, an external thread is arranged at the tail end B of the top pillar 401, the tail end B of the top pillar 401 is inserted into and penetrates through the through hole, and then the two nuts are respectively arranged on two sides of the supporting portion 101 and are respectively connected with the external thread of the tail end B.

In this embodiment, a preferable connection scheme between the top pillar 401 and the top pillar support rod 405 is provided, specifically:

a first threaded hole 406 (see fig. 3) is formed in the top pillar support rod 405;

the head end A of the top pillar 401 is provided with an external thread, and the head end A is in threaded connection with the first threaded hole 406.

Wherein, the head end a of the top pillar 401 is provided with an external thread, and the top pillar 401 can be connected to the first threaded hole 406 of the top pillar support rod 405 through the external thread; in the actual manufacturing and assembling process of the top pillar 401 and the top pillar support 405, the length of the top pillar 401 and the length of the top pillar support 405 are limited by materials and processing methods, and may have slight deviation, so that by connecting the top pillar 401 and the top pillar support 405 by screw threads, a fault-tolerant mechanism for the length of the top pillar 401 and the length of the top pillar support 405 is formed, that is, the structure formed by the top pillar 401 and the top pillar support 405 can be adjusted by screwing the top pillar 401.

Corresponding to the aforementioned 'connection scheme of the preferred top pillar 401 and the top pillar support 405', in the present embodiment, a connection scheme of the preferred top pillar 401 and the support portion 101 is proposed, specifically:

a second through hole 102 (see fig. 5) is provided on the support portion 101;

the second through hole 102 is coaxial with the first threaded hole 406, and the tail end B of the support rod 405 can be disposed in the second through hole 102, wherein the tail end B is in clearance connection with the second through hole 102.

In the above-mentioned 'preferred connection scheme of the top pillar 401 and the top pillar support rod 405', the top pillar 401 is adjustable with respect to the top pillar support rod 405, but when actually disposed on the handle 1, the tail end B of the top pillar 401 needs to be matched with the support portion 101, so that the effect of adjusting the top pillar 401 can be achieved when the 'top pillar 401 and the top pillar support rod 405' are disposed on the handle 1.

Therefore, the second through hole 102 is disposed on the supporting portion 101, so that the tail end B of the top pillar 401 can penetrate through the second through hole 102, that is, the tail end B of the top pillar 401 and the supporting portion 101 form a sliding pair. When the aforementioned 'connection scheme of the preferred top pillar 401 and the top pillar brace 405' is provided on the handle 1 together with the 'connection scheme of the preferred top pillar 401 and the support 101' herein, the head end a of the top pillar 401 is freely adjustable with respect to the top pillar brace 405, and the tail end B of the top pillar 401 is freely slidable with respect to the support 101 during adjustment of the head end a of the top pillar 401 with respect to the top pillar brace 405.

It should be understood that the purpose of the foregoing 'connection scheme of the preferred top pillar 401 and the top pillar brace 405' and 'connection scheme of the preferred top pillar 401 and the support portion 101' is not limited to only achieving adjustment of the top pillar 401, and hereinafter, the top pillar 401 has additional functions, which are not mentioned herein for the time being.

Up to this point, the present embodiment has solved the technical problem of 'how to set the post 401 on the handle 1' by the aforementioned 'connection scheme of the preferable post 401 and the post strut 405' and 'connection scheme of the preferable post 401 and the support portion 101'.

Further, in the above solution, how to arrange the support rod 405 on the handle 1 becomes a technical problem to be solved.

To solve this problem, the solution can be implemented by technical solutions known to those skilled in the art, such as: welding, riveting, screwing, etc.

In this embodiment, the following technical means is preferably adopted.

The handle 1 also has two side plates 103 (see fig. 3);

the two side plates 103 are respectively provided with a first through hole 104 (see fig. 3), and the two first through holes 104 are coaxially arranged;

the top pillar support rods 405 penetrate the two first through holes 104, respectively.

When actually manufacturing the top pillar brace 405, the top pillar brace 405 may be manufactured in a cylindrical shape, and a first threaded hole 406 penetrating through the top pillar brace 405 is provided at a middle position of the top pillar brace; by adopting the arrangement mode, the position of the first threaded hole 406 relative to the top pillar support rod 405 can be allowed to have smaller deviation, so that the fault tolerance rate of manufacturing the top pillar support rod 405 is increased, and the economic cost of manufacturing the top pillar support rod 405 is reduced; meanwhile, in order to increase the fault tolerance, the support rod 405 and the handle 1 need to be arranged as a sliding pair or a rotating pair, so that when the first threaded hole 406 actually deviates from the support rod 405, the deviation can be eliminated by adjusting the position of the support rod 405 relative to the handle 1; for example: both ends of the jack post 405 are a head end and a tail end, respectively, and if the position of the first threaded hole 406 with respect to the jack post 405 is biased toward the head end, the jack post 405 only needs to be adjusted in the head end to tail end direction when actually setting the combination of the jack post 405 and the jack post 401 on the handle 1, but the jack post 405 cannot be completely detached from the handle 1.

In the foregoing preferred embodiment, the two side plates 103 on the handle 1 are respectively provided with the first through holes 104, and the top pillar support rod 405 can respectively penetrate through the two first through holes 104, so that the top pillar support rod 405 and the handle 1 form a sliding pair or a rotating pair; meanwhile, if a deviation occurs in the position of the first threaded hole 406 with respect to the stud post 405 during the manufacturing process of the stud post 405, the position of the stud post 405 with respect to the two first through holes 104 may be adjusted, but the stud post 405 cannot be detached from any one of the first through holes 104.

In the actual assembly of the above-mentioned preferred embodiment, the support rod 405 of the top pillar may be first disposed in the two first through holes 104, and then the head end a of the top pillar 401 may be connected to the first threaded hole 406 of the support rod 405 of the top pillar.

Further, in the foregoing solution, the top pillar 401 and the top pillar support rod 405 are connected by a thread, and the top pillar 401 and the support portion 101 form a sliding pair, when the folder is actually used, the folder may be vibrated to cause the top pillar 401 to displace relative to the top pillar support rod 405, or even fall off, because the top pillar 401 and the support portion 101 do not fix to the support portion 101 although forming the sliding pair, thereby causing a technical problem that the top pillar 401 falls off relative to the top pillar support rod 405.

In this embodiment, the following preferable scheme is proposed to solve the technical problem that the jack 401 is separated from the jack support rod 405.

A second threaded hole 105 (see fig. 6) is also provided on the support portion 101;

the second through hole 102 and the second threaded hole 105 are in cross communication, wherein the second through hole 102 and the surface of the support part 101 form two mouths, and the second threaded hole 105 and the surface of the support part 101 form one mouth;

the second threaded hole 105 is used for installing a first set screw 5, wherein the first set screw 5 can contact the support post 405 in the second through hole 102.

The second screw hole 105 provided in the support portion 101 forms a tee-joint with the second through hole 102, so that the first set screw 5 is disposed in the second screw hole 105, and the first set screw 5 can contact and press the top pillar 401 located in the second through hole 102. The head end a of the prop 401 is connected with the prop strut 405 through a thread, so as to form a first connection position of the prop 401, and a first set screw 5 is adopted to press the prop strut 405 through the second threaded hole 105, so as to form a second connection position of the prop 401; in other words, originally, the tail end B of the top pillar 401 is not fixed to the supporting portion 101, and the first set screw 5 presses the top pillar support rod 405 through the second threaded hole 105, so that the effect that the top pillar 401 is fixed to the supporting portion 101 in a short position is achieved, and the technical problem that the top pillar 401 falls off relative to the top pillar support rod 405 is solved.

Further, in the foregoing, the handle hook 403 can slide relative to the handle 1 only when receiving an external force, and in order to apply an external force to the handle hook 403, a method in the prior art may be adopted, specifically:

referring to fig. 1 to 5, a push button 409 and a second hook screw 407 are further included;

the handle 1 is provided with a sliding groove, wherein one part of the push button 409 is movably arranged in the sliding groove, and the other part of the push button 409 and the handle hook 403 are separated by the handle 1;

the push button 409 and the handle hook 403 are connected by a second hook screw 407.

When the push button 409 and the handle hook 403 are connected by the second hook screw 407, the push button 409 is exposed outside the surface of the handle 1 and can be touched or pushed and pulled. At this time, if an external force is applied to the push button 409, the push button 409 can drive the handle hook 403 to move in the moving process of the push button 409 subjected to the external force, whereas if the push button 409 loses the external force, the push button 409 and the handle hook 403 are restored to the original position under the action of the spring 402.

Further, in the foregoing, it has been proposed that the function of the top pillar 401 is not limited to only achieving adjustment of the top pillar 401. When the handle 1 is connected to the upper end cover 3 through the locking part, the hook 404 and the handle hook 403 are connected in the radial direction, so that the handle 1 and the upper end cover 3 are connected in the radial direction through the locking part; however, if there is a gap in the connection between the hook 404 and the handle hook 403, the upper cap 3 and the lower cap 2 may be turned over in a limited manner during actual use, so that the connection between the upper cap 3 and the lower cap 2 is not stable.

In order to solve the problem of connection between the upper end cover 3 and the lower end cover 2, the following scheme is preferably adopted:

referring to fig. 2 or fig. 3, the upper end cover 3 is provided with a top column screw 302;

the top post screw 302 and the upper end cap 3 are adjustably connected, wherein the rear end B of the top post 401 can contact the top post screw 302 when the hook 404 and the handle hook 403 are hooked to each other.

When the handle 1 is connected to the upper end cover 3 through the locking member, the top pillar 401 on the handle 1 may contact and press the top pillar screw 302, so that a supporting force is formed between the upper end cover 3 and the lower end cover 2 through the top pillar 401 and the top pillar screw 302 in the axial direction, the direction of the supporting force is the axial direction, and the direction of the aforementioned hooks 404 and the handle hooks 403 is the radial direction; due to the existence of the supporting force, the aforementioned phenomenon that 'a gap' may occur in the connection between the hook 404 and the handle hook 403 is eliminated, because the supporting force causes the handle 1 to form 'a force that moves the handle 1 away from the upper cap 3' with respect to the upper cap 3, thereby forcing the hook 404 to be hooked by the handle hook 403 on the handle 1, and thus eliminating the gap 'that may occur in the connection between the hook 404 and the handle hook 403'.

In addition to the foregoing, in this embodiment, a foldable mobility tool is provided, including a folder as described above. Specifically, the travel tool may be a foldable electric bicycle, a foldable non-electric bicycle, a foldable electric scooter, a foldable non-electric scooter, a foldable electric wheelchair, and a foldable non-electric wheelchair.

It should be understood that the aforementioned folders can be applied to a foldable electric bicycle, a foldable non-electric bicycle, a foldable electric scooter, a foldable non-electric scooter, a foldable electric wheelchair, and a foldable non-electric wheelchair, respectively, and should not be construed as: the aforementioned folder can be applied to only one of the above-described walk-substituting tools.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
