[0041] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0042] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0046] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0047] As described in the background technology: when the folding bicycle switches from the unfolded state to the folded state, one end of the cable connected to the head tube or the main beam tube moves synchronously with the first section relative to the second section, while the other end of the cable cannot twist automatically and is easily stuck, which is not conducive to the folding of the folding bicycle.
[0048] The applicant has found that the root cause of the above problems is that the cable includes a pull wire and an end connected to each other. The cable is hinged to the five-way bracket through the end, and the cable can rotate relative to the five-way bracket through the end, so that the folding bicycle can switch between the unfolded state and the folded state. When the folding bicycle switches from the unfolded state to the folded state, the first section of the main beam tube rotates relative to the second section, driving the cable to move toward the rear wheel. When the cable moves toward the rear wheel, there is a tendency to bend between the end connected to the five-way bracket, and when the bending reaches a certain degree, the tension of the cable is not enough to drive the end to rotate relative to the five-way bracket, causing the end to suffocate.
[0049] For the above questions, see Figure 1 and Figure 2 In one embodiment of the present application, a folding frame 100 is provided, comprising a main beam tube 10, a head tube component 30 and a seat tube 40. The main beam tube 10 comprises a first section 11 and a second section 12 connected to each other, and the first section 11 and the second section 12 are connected by a folder 20, so that the folding frame 100 can be folded. The head tube component 30 is connected to an end of the first section 11 away from the second section 12, and the seat tube 40 is connected to an end of the second section 12 away from the first section 11. Figure 3 The folding frame 100 further includes a five-way component 50, which is connected to the seat tube 40. The head tube component 30 is used to install the front fork 60, the seat tube 40 is used to install the seat, and the five-way component 50 is used to install the pedal.
[0050] Continue reading Figure 1-Figure 3The folding frame 100 also includes a cable 70, and the two ends of the cable 70 form a first end 71 and a second end 72 respectively. Further, the cable 70 also includes a pull wire 73 arranged between the second end 72 and the first end 71, and specifically, the pull wire 73 is a steel wire. It is conceivable that the pull wire 73 can also be prepared and formed by other materials, which is not limited here. The second end 72 is connected to the first section 11 and / or the head pipe component 30, and the first end 71 is hinged to the five-way component 50 and / or the structure connected to the five-way component 50. The structure hinged to the first end 71 is defined as an articulated structure. Specifically, the first end 71 can rotate relative to the articulated structure around a first axis parallel to the axial direction of the five-way component 50.
[0051] In some specific embodiments, the first end 71 is hinged to the five-way component 50, and the hinged structure is the five-way component 50. In other specific embodiments, the first end 71 is hinged to the seat tube 40, and the hinged structure is the seat tube 40. In still other specific embodiments, the folding frame 100 further includes a reinforcing tube 110, the two ends of the reinforcing tube 110 are respectively connected to the second section 12 and the five-way component 50, the first end 71 is hinged to the reinforcing tube 110, and the hinged structure is the reinforcing tube 110. It is conceivable that in some other embodiments, the first end 71 can also be connected to and hinged to two different components, and the two components hinged to the first end 71 are hinged structures.
[0052] The folding frame 100 further includes an action member. When the folding frame 100 switches from the unfolded state to the folded state, the action member can apply a torsional force to the first end 71, and the first end 71 can rotate relative to the hinge structure under the action of the torsional force. That is, when the first section 11 rotates relative to the second section 12 through the folder 20 so that the folding frame 100 switches from the unfolded state to the folded state, the action member can apply a torsional force to the first end 71, prompting the first end 71 to automatically rotate relative to the hinge structure, thereby preventing the first end 71 from being stuck (stuck) when the folding frame 100 is folded. It should be noted that the first end 71 being stuck (stuck) means that when the folding frame 100 is folded, the first end 71 cannot rotate relative to the hinge structure, and remains in the position when the folding frame 100 is in the unfolded state; or, the first end 71 rotates slightly relative to the hinge structure, but its rotation angle is limited, which is not conducive to the folding of the folding frame 100.
[0053] It should be noted here that Figure 3 The middle arrows represent the folding direction of the folding frame 100 and the twisting direction of the first end 71 relative to the hinge structure.
[0054] The folding frame 100 provided in the embodiment of the present application can automatically rotate relative to the hinge structure under the action of the torsional force applied by the action member when the folding frame 100 is switched from the unfolded state to the folded state, so as to avoid the first end 71 being suffocated when the folding frame 100 is folded, thereby facilitating the folding of the folding frame 100.
[0055] Optionally, both ends of the cable 70 are detachably connected to the head pipe component 30 and the hinge structure, respectively, so that the cable 70 can be replaced when damaged.
[0056] In some embodiments, the first end 71 is hinged to the front side of the five-way member 50. The first end 71 can rotate upward relative to the five-way member 50 under the action of a torsional force, so as to facilitate the folding of the folding frame 100.
[0057] It should be noted that when the folding frame 100 is applied to the folding bicycle 1000, the front side of the five-way component 50 is the side thereof facing the front wheel, the rear side is the side of the five-way component 50 facing the rear wheel, the upper side is the side of the five-way component 50 facing away from the ground, and the lower side is the side of the five-way component 50 facing the ground. The first end 71 can rotate upward relative to the five-way component 50 under the action of the torsion force, which means that the first end 71 can rotate relative to the five-way component 51 to the side facing away from the ground under the action of the torsion force. It is understandable that in other embodiments, the first end 71 can also be hinged to the upper side or the lower side of the five-way component 50.
[0058] In some embodiments, see Figure 2 The five-way component 50 includes a five-way 51 and a mounting member 52, and the mounting member 52 is installed in the five-way 51. The mounting member 52 is configured to realize a rotational connection between the spindle and the five-way 51. The pedal assembly is connected to the spindle. Specifically, the mounting member 52 is fixedly installed in the five-way 51. Figure 1 The bottom bracket 50 further includes a first connecting ring 53, which is sleeved outside the mounting member 52 and relatively fixed to the mounting member 52. That is, the mandrel can rotate relative to the bottom bracket 51, the mounting member 52 and the first connecting ring 53. It is conceivable that in other embodiments, the first connecting ring 53 can also be sleeved outside the bottom bracket 51.
[0059] Furthermore, a first hinge portion 531 is convexly disposed on the first connecting ring 53, and the first end 71 is hingedly connected to the first hinge portion 531. In this way, the connection between the first end 71 and the five-way bracket 51 can be achieved without modifying the folding frame 100, which is convenient to use and has low cost.
[0060] Of course, in other implementations, the first hinged portion 531 may also be protruded on the five-way joint 51, which is not limited here. It should be understood that when the first end 71 is hinged to other components, the first hinged portion 531 may also be provided on other components.
[0061] In some embodiments, the action member is an elastic member, and the elastic member is disposed between the first hinge portion 531 and the first end 71. When the folding frame 100 is switched from the folded state to the unfolded state, the elastic member is elastically deformed to store energy. When the folding frame 100 is switched from the unfolded state to the folded state, the elastic member is reset to provide the above-mentioned torsional force to the first end 71.
[0062] When the folding frame 100 switches from the folded state to the unfolded state, the first end 71 rotates in the forward direction driven by the first section 11, and no jamming occurs. The force required to resist the elastic member is not large, that is, the setting of the elastic member does not hinder the rotation of the first end 71. When the folding frame 100 is in the unfolded state, the elastic member elastically stores energy under the action of the first end 71. When the folding frame 100 switches from the unfolded state to the folded state, the elastic force generated when the elastic member is reset provides the above-mentioned torsional force to realize the automatic rotation of the first end 71 relative to the first hinge 531, thereby preventing the first end 71 from being stuck. The elastic member is light and has a low cost.
[0063] For further information, see Figure 4 The elastic member is a torsion spring 80, and the first end 71 is hinged to the first hinge portion 531 through a first pin 90. Figure 5 , the first pin shaft 90 includes a first portion 91 and a second portion 92, the first portion 91 is inserted through the first hinge portion 531 and the first end 72, and the second portion 92 is locked with the first portion 91. The torsion spring 80 includes a first end portion 81, a middle portion 82 and a second end portion 83 which are connected in sequence. The middle portion 82 is sleeved on the outside of the first portion 91 of the first pin shaft 90, the first end portion 81 is fixedly connected to the first hinge portion 531, and the second end portion 83 is fixedly connected to the first end 71. In this way, when the folding frame 100 switches from the folding state to the unfolding state, the torsion spring 80 deforms and stores energy; and when the folding frame 100 switches from the unfolding state to the folding state, the torsion spring 80 provides the above-mentioned torsional force to the first end 71.
[0064] It is conceivable that in other embodiments, the elastic member may also be a tension spring, one end of which is connected to the first hinge portion 531, and the other end of which is connected to the first terminal 71. When the folding frame 100 is switched from the folded state to the unfolded state, the tension spring is deformed to store energy. When the folding frame 100 is switched from the unfolded state to the folded state, the tension spring provides the above-mentioned torsional force to the first terminal 71.
[0065] For further information, see Figure 6The first hinge portion 531 is provided with a first fixing hole 5311, and the first end portion 81 is passed through and fixed in the first fixing hole 5311. The first end 71 is provided with a second fixing hole 711, and the second end portion 83 is passed through and fixed in the second fixing hole 711. Such a configuration facilitates the installation and fixation of the torsion spring 80.
[0066] In other embodiments, the action member is a driving member, and the driving member is installed on the hinge structure. Specifically, the driving member is installed on the five-way 51, and when the folding frame 100 switches from the unfolded state to the folded state, the driving member can apply the above-mentioned torsional force to the first terminal 71. The driving member is used as the action member to apply the torsional force to the first terminal 71, which ensures the reliability of the torsion of the first terminal 71. In some specific embodiments, the driving member is a motor. It is conceivable that in other embodiments, the driving member can also be a cylinder, which is not limited here.
[0067] In some embodiments, the second end 72 is connected to the head tube component 30. Compared with the case where the second end 72 is connected to the first section 11, the arrangement of the cable 70 can not only improve the strength of the main beam tube 10, the seat tube 40 and the bottom bracket component 50, but also improve the strength of the head tube component 30, thereby enhancing the reinforcement effect of the cable 70. It is conceivable that in other embodiments, the second end 72 can be arranged to be connected to the first section 11, or to be connected to both the head tube component 30 and the first section 11, which is not limited here.
[0068] Further reading Figure 1 and Figure 2 The head tube component 30 includes a head tube 31, a bowl set 32 and a second connecting ring 33. The bowl set 32 is mounted on the head tube 31, and the second connecting ring 33 is sleeved outside the bowl set 32. The bowl set 32 is configured to achieve a rotational connection between the front fork 60 and the head tube 31. That is, the front fork 60 is rotationally connected to the head tube 31 through the bowl set 32. It should be understood that in other embodiments, the second connecting ring 33 can also be sleeved outside the head tube 31.
[0069] Continue reading Figure 3 The second connecting ring 33 is provided with a second hinged portion 331, and the second end 72 is hinged to the second hinged portion 331. The second end 72 can rotate relative to the head tube component 30 around a second axis parallel to the axial direction of the head tube component 30. In this way, there is a movable space between the cable 70 and the head tube 31, which facilitates the unfolding and folding of the folding frame 100.
[0070] It is conceivable that in some other embodiments, a connecting portion is welded on the head pipe 31, and the second end 72 is connected to the connecting portion.
[0071] See also Figure 7-10Another embodiment of the present application further provides a folding bicycle 1000, comprising the above-mentioned folding frame 100. Since the folding frame 100 has beneficial effects, the folding bicycle 1000 has the same beneficial effects accordingly, which will not be described in detail here.
[0072] Continue reading Figure 7 and Figure 8 The folding bicycle 1000 further includes a wire harness 200 and a handlebar 300. The handlebar 300 is connected to the head assembly 30, and one end of the wire harness 200 is connected to the handlebar 300. The folding bicycle 1000 further includes a stopper 400. The stopper 400 is mounted on the folding frame 100. Specifically, the stopper 400 is mounted on the head tube 31 of the head tube component 30. It is conceivable that in some other implementations, the stopper 400 is not mounted on the head tube component 30, and can also be mounted on the main beam tube 10, the vertical tube or the basket of the folding frame 100.
[0073] The stopper 400 includes a stop ring 401. The other end of the wire harness 200 passes through the stop ring 401 and is at least partially bound to the pull wire 73 of the cable 70. Fig. 9 and Fig.10 When the handlebar 300 is folded, the limiting ring 401 can limit the wire harness 200, so that the wire harness 200 follows the handlebar 300 and is folded to the same side of the head tube component 30. For example, in some specific embodiments, the wire harness 200 and the handlebar 300 are both folded to the left side of the head tube component 30. It should be noted that the left side is based on the rider's riding standard, and the left side of the head tube component 30 is the rider's left side.
[0074] With the above arrangement, on the one hand, when the handlebar 300 is unfolded, the limiting ring 401 can limit the wire harness 200 to arrange the wire harness 200 in an orderly manner; on the other hand, when the handlebar 300 is folded, the limiting ring 401 can limit the wire harness 200, and the wire harness 200 can be folded together with the handlebar 300 to the same side of the head pipe component 30, so as to prevent the wire harness 200 from running around when folded, and make the wire harness 200 arranged in an orderly manner.
[0075] In some embodiments, the wire harness 200 includes a brake wire and a gearshift wire. In some other embodiments, the wire harness 200 may only include a brake wire.
[0076] Furthermore, the limiting member 400 is a torsion spring, one end of which is connected to the folding frame 100, and the other end forms a limiting ring 401. When the handlebar 300 drives the wiring harness 200 to unfold, the torsion spring stores energy; when the handlebar 300 is folded, the torsion spring can apply elastic force to the wiring harness 200, so that the wiring harness 200 is folded. In this way, when the handlebar 300 is folded, the torsion spring is reset, and the wiring harness 200 can be folded under the elastic force of the torsion spring, and the wiring harness 200 is convenient to fold.
[0077] It is conceivable that in some other embodiments, the limiting member 400 may also be a rigid member without elasticity, which is not limited here.
[0078] Furthermore, the limiting ring 401 has an opening, so that the wire harness 200 can be passed through the opening and arranged in the limiting ring 401. It is conceivable that in some other embodiments, the limiting ring 401 can also be a closed ring structure, which is not limited here.
[0079] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0080] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
