Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the field of bicycles, and more particularly to a support device for a bicycle and a bicycle. Background Art

[0002] The support device (also known as the side support) is a component used to support a bicycle with two wheels, such as a bicycle or an electric bicycle, and is capable of supporting the bicycle when it is parked. For some electric motorcycle models, there are some problems with the support device that may interfere with the rider. Specifically, the rider's feet or pedals are likely to interfere with the support device during riding, which not only affects the driving comfort, but may also pose a hidden danger to driving safety. In addition, the support devices in bicycles currently usually adopt a unilateral installation method. This installation method has high requirements on the assembly precision and is prone to deformation of the support or loosening of the screws, which not only increases the maintenance cost, but also affects the stability and durability of the vehicle. Utility Model Content

[0003] In a first aspect of the present disclosure, a support device for a bicycle is provided. The support device comprises: a fixing member comprising a U-shaped portion and a connecting portion, the U-shaped portion being fixed to a fork arm of a bicycle chain stay and arranged to partially cover the fork arm, the connecting portion extending obliquely outward from a portion of the U-shaped portion located inside the fork arm; and a support member comprising a coupling portion and a support leg respectively located at both ends of the support member in an extending direction, the coupling portion being adapted to be rotatably coupled to the connecting portion to allow the support member to rotate between a supporting position and a stowed position, wherein in the supporting position, the support leg contacts the ground to support the bicycle.

[0004] In some embodiments, the fixing component also includes: an outer member, the cross-section of the outer member is L-shaped and is suitable for coupling to the outer side of the fork arm, the outer member includes a pair of first coupling holes; an inner member, including an inner side portion and a connecting portion extending obliquely outward from the inner side portion, the inner side portion includes a pair of second coupling holes, the pair of second coupling holes and the pair of first coupling holes are respectively aligned for a pair of fasteners to pass through them and the fork arm, thereby fixing the fixing component to the fork arm; and a connecting shell, coupled to the end of the connecting portion away from the inner side portion, and suitable for coupling to and jointly covering the coupling portion of the support component with the inner side portion.

[0005] In some embodiments, the connecting shell includes: a bottom wall including a first rivet hole; and a plurality of side walls extending in a direction perpendicular to the bottom wall and coupled to the inner piece to form a space for accommodating the coupling part, and the inner piece includes a second rivet hole aligned with the first rivet hole.

[0006] In some embodiments, the support device further includes: a rivet, which passes through the first rivet hole, the coupling portion of the support component, and the second rivet hole in sequence along the axial direction to couple the support component to the fixing portion of the fixing component, and the rivet serves as a rotation axis for the support component to rotate.

[0007] In some embodiments, the outer member, the inner member, and the connecting shell are welded to form the fixing member.

[0008] In some embodiments, the cross-section of the support component is generally U-shaped.

[0009] In some embodiments, the supporting device further includes: a reinforcing sheet arranged between the coupling portion of the supporting component and the connecting portion of the fixing component.

[0010] In some embodiments, the reinforcement sheet is fixed to the coupling portion by welding and includes: a reinforcement portion arranged to abut the end of the side wall of the support component; and an extension portion extending from the reinforcement portion toward the support foot and arranged between the side walls of the support component.

[0011] In some embodiments, the reinforcement portion of the reinforcement sheet includes a through hole for the rivet to pass through.

[0013] According to the disclosed embodiment, the connecting portion extends outward at an angle from the U-shaped portion located on the inner side of the fork arm. This arrangement allows the support component to be positioned inward (i.e., toward the wheel), avoiding interference with the pedals and effectively preventing interference between the foot or pedal and the support component, thus improving riding safety. Furthermore, by coupling the U-shaped portion to the fork arm, structural stability is enhanced, effectively preventing deformation of the support device and loosening of screws.

[0014] It should be understood that the content described in this content section is not intended to limit the key features or important features of the embodiments of the present disclosure, nor is it intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or identical objects.

[0021] The support device (also known as the side support) is an important component of two-wheeled vehicles (also known as bicycles) such as bicycles and electric bicycles. Its design and function directly affect the stability of the vehicle and the user experience. However, the existing support device has design defects in some electric motorcycle models. In particular, when used by the rider, the support device is prone to interference with the feet or pedals, which not only reduces driving comfort but also may pose a safety hazard. In addition, the unilateral installation method of the support device requires high assembly precision, which can easily lead to support deformation or loose screws, which not only increases maintenance costs but also affects the stability and durability of the vehicle.

[0022] Embodiments of the present disclosure provide a support device for a bicycle to solve or at least partially solve the above-mentioned problems or other potential problems existing in traditional support devices. Figure 1 and Figure 2 Schematic diagrams showing a support device coupled to a vehicle body according to an embodiment of the present disclosure viewed from different angles are shown; Figure 3 A perspective view showing the support device coupled to the vehicle body; and Figure 4An exploded view of the support device is shown.

[0023] like Figures 1 to 4 As shown, in general, the support device according to the embodiment of the present disclosure includes a fixing component 101 and a support component 102. The fixing component 101 includes a U-shaped portion 1011 and a connecting portion 1012. The U-shaped portion 1011 is fixed to a fork arm 201 in the rear chain stay of the bicycle, and is arranged to partially cover the fork arm 201 of the bicycle. Different from the traditional unilateral fixing method, the fixing component 101 according to the embodiment of the present disclosure uses the U-shaped portion 1011 to cover the fork arm 201, thereby improving the coupling strength between the fixing component 101 and the fork arm 201, increasing the structural stability, and thus effectively avoiding deformation and other problems.

[0024] The connection portion 1012 of the fixing member 101 is used to connect with the supporting member 102. Figures 1 to 4 As can be seen, the connection portion 1012 according to the embodiment of the present disclosure extends outwardly from the portion of the U-shaped portion 1011 located inside the fork arm 201. In this way, compared to a single-sided support method fixed to the outside of the fork arm 201, the support member 102 can be arranged inward (i.e., in the direction of the wheel), thereby avoiding the interference range of the pedals and effectively preventing interference between the foot or pedal and the support member 102, thereby improving riding safety.

[0025] The support component 102 includes a coupling portion 1021 and a support foot 1022, which are respectively located at both ends of the extension direction thereof. The coupling portion 1021 is adapted to be rotatably coupled to the connecting portion 1012 to allow the support component 102 to rotate between a support position and a stowed position. In the support position, the support foot 1022 contacts the ground to support the bicycle. In the stowed position, the support foot 1022 leaves the ground, and the support component is generally in a horizontal direction, thereby facilitating the user to ride the bicycle. The support device according to the embodiment of the present disclosure can effectively avoid interference between the user's feet or pedals and the support device by arranging the support component 102 inward, thereby improving riding safety. In addition, by using the U-shaped portion 1011 to couple to the fork arm 201, the structural stability can be improved, and deformation of the support device and loosening of screws can be effectively avoided.

[0026] In some embodiments, the cross-section of the support member 102 may be U-shaped as a whole. The U-shaped support member 102 is easier to manufacture and can also enhance the strength of the support member 102.

[0027] In some embodiments, the fixing component 101 can be welded or assembled from multiple components. Specifically, the fixing component 101 includes an outer member 1013, an inner member, and a connecting shell 1017. The outer member 1013 has an L-shaped cross-section and is suitable for coupling to the outer side of the fork arm 201. A pair of coupling holes are provided on the outer member 1013. For ease of description below, the coupling holes on the outer member 1013 will be referred to as first coupling holes 1014.

[0028] The inner member includes an inner portion 1015 and the aforementioned connecting portion 1012 extending obliquely outward (i.e., away from the wheel) from the inner portion 1015. The outer member 1013 and the inner portion 1015 of the inner member form the aforementioned U-shaped portion 1011. The obliquely extending connecting portion 1012 is adapted to be coupled obliquely thereto by the support member 102, thereby facilitating support of the bicycle. The inner portion 1015 includes a pair of second coupling holes 1016. The pair of second coupling holes 1016 and the pair of first coupling holes 1014 are aligned to allow a pair of fasteners 1031 to pass therethrough and to the fork arm 201, thereby securing the fixing member 101 to the fork arm 201.

[0029] In some embodiments, fastener 1031 may include a screw and a nut 1032. During assembly, after U-shaped portion 1011 wraps around fork arm 201 from below, the through-holes on fork arm 201 align with the corresponding first coupling holes 1014 and second coupling holes 1016, facilitating the screw's passage. After passing through first coupling hole 1014, the through-holes on fork arm 201, and second coupling hole 1016, the screw couples with nut 1032, securing U-shaped portion 1011 to fork arm 201.

[0030] The connecting shell 1017 of the fixing member 101 is coupled to the end of the connecting portion 1012 away from the inner portion 1015, and is adapted to be coupled to the coupling portion 1021 of the supporting member 102 and, together with the inner portion 1015, cover the coupling portion 1021 of the supporting member 102. In some embodiments, the connecting shell 1017 may include a bottom wall 1018 and a plurality of side walls 1019. The plurality of side walls 1019 extend in a direction perpendicular to the bottom wall 1018. The bottom wall 1018, the plurality of side walls 1019, and the inner portion 1015 together form a space for accommodating the coupling portion 1021. To prevent interference with the connecting shell 1017 caused by the support member 102 during rotation, the side walls 1019 of the connecting shell 1017 located at the rear are shorter, thereby forming an escape portion to prevent interference between the supporting member 102 and the side walls 1019 in the retracted position.

[0031] The bottom wall 1018 is provided with a first rivet hole 1010, and the connecting portion 1012 is provided with a second rivet hole 1020 aligned with the first rivet hole 1010. The coupling portion 1021 of the support component 102 is also provided with a through hole for the rivet 103 to pass through. When coupling the support component 102 to the fixing component 101, the rivet 103 is sequentially passed axially through the first rivet hole 1010, the through hole of the coupling portion 1021 of the support component 102, and the second rivet hole 1020 to couple the support component 102 to the fixing portion 101 of the fixing component 101. The rivet also serves as the rotation axis for the support component 102 to rotate. Using the rivet as the rotation axis prevents the support component 102 from loosening or falling off.

[0032] In some embodiments, the outer member 1013, the inner member, and the connecting shell 1017 can be made of sheet metal and welded to form the fixing member 101. This method allows for more convenient and cost-effective manufacturing of the fixing member 101. Of course, it should be understood that the fixing member 101 can also be manufactured using any other suitable method, including but not limited to: connection with fasteners 1031, integral molding, and the like.

[0033] In some embodiments, to increase the strength of the support member 102 at the coupling portion 1021, the support device may further include a reinforcing sheet 104 disposed between the coupling portion 1021 of the support member 102 and the connecting portion 1012 of the fixing member 101. In some embodiments, the reinforcing sheet 104 is fixed to the coupling portion 1021 by welding and has a certain length in the extension direction of the support member 102.

[0034] The reinforcement plate 104 may include a reinforcement portion 1041 and an extension portion 1042. The reinforcement portion 1041 is positioned to abut the ends of the side walls of the support component 102 and is welded thereto. The extension portion 1042 extends from the reinforcement portion 1041 toward the support legs 1022 and is positioned between the side walls. To achieve this arrangement, the side wall of the support component 102 corresponding to the reinforcement portion 1041 may be positioned lower than the rest of the side wall, thereby forming a first step between the portion of the side wall corresponding to the reinforcement portion 1041 and the rest of the side wall. Correspondingly, a second step may be provided between the reinforcement portion 1041 and the extension portion 1042 of the reinforcement plate 104. The abutment of the first and second steps allows the reinforcement portion 1041 to be positioned at the ends of the side walls 1019, while the extension portion 1042 is positioned between the side walls. This facilitates the positioning and assembly of the reinforcement plate 104 and the support component 102, improving assembly efficiency.

[0035] In some embodiments, the reinforcement sheet 104 may include a through hole for the rivet 103 to pass through. The through hole may be arranged on the reinforcement portion 1041 of the reinforcement sheet 104. The through hole may have a size larger than the diameter of the rivet 103 so as not to interfere with or cause friction to the rotation of the support component 102.

[0036] The present disclosure also provides a bicycle. This bicycle includes the aforementioned support device. This support device effectively prevents interference between the foot or pedal and the support member 102, improving riding safety. Furthermore, by coupling the U-shaped portion 1011 to the fork arm 201, structural stability is enhanced, effectively preventing deformation of the support device and loosening of screws.

[0037] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
