Description

Technical Field

[0001] This invention relates to vehicles, and more particularly to a mounting structure for a bicycle basket, and a bicycle using the mounting structure. Background Technology

[0002] Currently, bicycles typically carry passengers or goods on the back seat. If a child is sitting on the back, the rider cannot see the child, making it difficult to assess potential dangers in time. Similarly, if goods are carried on the back, the lack of visibility can lead to items falling off and other situations that cannot be dealt with promptly.

[0003] Therefore, a bicycle with a passenger or cargo bed positioned in front of the handlebars has already been developed. For example, Chinese Patent Application No. 202422081609.8 discloses a novel front-bed two-wheeled electric bicycle, which includes a cargo bed, frame, saddle, chain drive system, steering mechanism, a front wheel, a rear wheel, and a battery. The cargo bed includes a chassis, two "arc-shaped" panels and two straight panels. The lower "arc-shaped" panels of the cargo bed are fixedly connected to the front curved tube of the main frame by several fixing blocks. The bottom of the cargo bed is fixedly connected to several crossbeams set in the middle of the main frame by several fixing blocks. The higher "arc-shaped" panels of the cargo bed are fixedly connected to the handlebars by several fixing blocks.

[0004] This type of bicycle uses fixing blocks to secure the basket to the frame and handlebars. This fixing method usually requires the use of screws and other fasteners, so both assembly and disassembly require tools to operate the screws, making them inconvenient. This is especially true when the installation location restricts the use of tools, further increasing the difficulty of assembly and disassembly.

[0005] Therefore, further improvements are needed. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a bicycle basket mounting structure that allows for convenient and quick assembly and disassembly of the bicycle basket.

[0007] The second technical problem to be solved by the present invention is to provide a bicycle with the above-described mounting structure.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a bicycle basket mounting structure, including a bicycle basket and an mounting structure for mounting the bicycle basket to a mounting base of the bicycle basket; The mounting structure includes: A mounting base, which is fixed to the truck bed, the mounting base including a locking hole; and A locking mechanism, which is directly or indirectly mounted to the mounting base, the locking mechanism including a pin, the locking mechanism being capable of locking and unlocking the mounting base, and the locking mechanism maintaining a tendency to lock the mounting base: when in the locked state, the pin is inserted into the keyhole, and when in the unlocked state, the pin is disengaged from the keyhole.

[0009] By setting up a cooperative structure between the mounting base and the locking mechanism, the locking mechanism locks or unlocks with the mounting base in a manner similar to a spring-loaded pin. This can be accomplished simply by making the pin move in a straight line, without the need for external tools or being limited by the installation environment, allowing for quick assembly and disassembly of the truck bed.

[0010] Furthermore, when the locking mechanism is in the unlocked state, the pin remains in the disengaged position. Therefore, during the installation and removal of the truck bed, no additional force is required to keep the pin in the unlocked position; installation and removal can be completed with just one hand.

[0011] Furthermore, the mounting base is recessed towards the pin to form the lock hole; the locking mechanism also includes a first sleeve and a second sleeve, the second sleeve being directly or indirectly fixed to the mounting base, the first sleeve being sleeved around the outer periphery of the second sleeve, the pin having two opposing ends, one end of which is fixed to the first sleeve, the pin passing through the second sleeve, and when the locking mechanism is in the locked state, the other end of the pin protruding from the second sleeve and inserting into the lock hole; when the locking mechanism is in the unlocked state, the second sleeve applies a force to the first sleeve away from the mounting base, causing the pin to remain retracted within the second sleeve. Through the cooperation of the first sleeve and the second sleeve, in the unlocked state, the second sleeve can apply a force to the first sleeve, keeping the first sleeve (along with the pin) in a stable position.

[0012] Furthermore, the first sleeve includes a first cylindrical body, a first slot formed within the first cylindrical body, and a second slot formed within the first cylindrical body. The second slot is located on the side of the first slot facing the mounting base, and the two slots are interconnected. The second slot passes through the top of the first sleeve facing the mounting base. The second sleeve includes a second cylindrical body, and the cross-sections of the first slot and the second cylindrical body are adapted to be non-circular; When the locking mechanism is in the locked state, the second cylinder is inserted into the first slot and the second slot; When the locking mechanism is in the unlocked state, the first sleeve moves linearly away from the mounting base relative to the second sleeve and rotates relative to the second sleeve, so that the bottom surface of the second sleeve abuts against the top surface of the first slot, thereby defining the position of the first sleeve. The bottom surface of the second sleeve is the end face away from the mounting base, and the top surface of the first slot is the end face facing the mounting base.

[0013] The misalignment is generated by the relative linear movement of the first and second sleeves. Since the cross-sections of the first slot and the second cylinder are non-circular, the misalignment of the edges, corners or other shapes can be generated after the first sleeve rotates relative to the second sleeve. This allows at least a portion of the cylinder to abut against each other in the linear movement direction. Furthermore, when locking is required again, the first sleeve can rotate relative to the second sleeve to return to the angle where the cylinder of the second sleeve can be completely accommodated in the first slot. This makes the operation convenient.

[0014] Furthermore, the locking mechanism also includes an elastic element that abuts against the pin and the second cylinder respectively, so that the pin maintains the tendency to move out of the second sleeve and insert into the lock hole.

[0015] Furthermore, to facilitate the installation of the aforementioned mounting base and locking mechanism, the mounting structure further includes a mounting bracket assembly, which is mounted to the mounting base of the bicycle; the mounting base is slidably connected to the mounting bracket assembly, such that the mounting base is limited within or disengaged from the mounting bracket assembly, and the locking mechanism is also mounted to the mounting bracket assembly.

[0016] Furthermore, the mounting bracket assembly has a first groove and a second groove formed thereon. The first groove and the second groove respectively penetrate the side of the mounting bracket assembly away from the locking mechanism. The first groove and the second groove are adjacent to each other and communicate with each other. The mounting seat can slide between the first groove and the second groove. The mounting seat can be inserted into or detached from the mounting bracket assembly from the second groove. The mounting seat can be confined at the first groove. Thus, the mounting seat can be easily installed and detached from the mounting bracket assembly by sliding the truck bed, making operation very convenient.

[0017] Furthermore, the first groove includes a first groove portion and a second groove portion that are interconnected. The width of the first groove portion is smaller than the width of the second groove portion. The width direction of the first groove portion is perpendicular to the sliding direction of the mounting base. The mounting base includes a first connecting portion for fixing to the truck bed, a second connecting portion that can be placed in the second groove portion, and a third connecting portion that can be placed in the first groove portion. The first groove portion defines the position of the third connecting portion in the pin movement direction. Here, the pin movement direction refers to its linear movement direction for locking or unlocking with the mounting base, thereby preventing the mounting base from disengaging from the mounting bracket assembly.

[0018] The first technical solution adopted by the present invention to solve the second technical problem mentioned above is: a bicycle, including a frame, characterized in that: the bicycle further includes a bicycle basket mounting structure as described above, the frame serving as the mounting base for the bicycle basket.

[0019] The second technical solution adopted by the present invention to solve the second technical problem mentioned above is: a bicycle, including a frame, characterized in that: the bicycle further includes a bicycle basket mounting structure as described above, the frame serving as the mounting base for the bicycle basket; the frame includes a crossbeam;

[0020] The mounting bracket assembly includes a first mounting bracket and a second mounting bracket. The first mounting bracket spans across the crossbeam, and the second mounting bracket is supported on the side of the crossbeam. The first mounting bracket and the second mounting bracket are connected and fixed.

[0021] The mounting base is mounted to the first mounting bracket, the locking mechanism is mounted to the second mounting bracket, and the pin passes through the second mounting bracket and the first mounting bracket from bottom to top to cooperate with the mounting base.

[0022] The aforementioned independent first and second mounting brackets facilitate the assembly and disassembly of the frame and mounting bracket components, while also ensuring the stability of the truck bed installation.

[0023] Compared with the prior art, the advantages of the present invention are: by setting a cooperative structure between the mounting base and the locking mechanism, the locking mechanism locks or unlocks with the mounting base in a manner similar to an elastic pin. This can be accomplished simply by making the pin move in a straight line, without the need for external tools or being limited by the installation environment, thus allowing for quick assembly and disassembly of the truck bed.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0040] Example 1

[0041] See Figures 1-9 A bicycle, which can be either a human-powered bicycle or an electric bicycle, includes a frame 1, a basket 2, a seat 3, handlebars 4, a front wheel 5, and a rear wheel 6. The frame 1 includes a crossbeam 11, a first support 12 mounted on the crossbeam 11, and a second support 13 mounted on the crossbeam 11. The front wheel 5 is located at the front of the crossbeam 11, and the rear wheel 6 is located at the rear of the crossbeam 11. The first support 12 and the second support 13 extend upward from the crossbeam 11, with the second support 13 positioned close to the rear wheel 6, and the first support 12 located between the front wheel 5 and the second support 13. The seat 3 is located on top of the second support 13, and the handlebars 4 are located on top of the first support 12. The direction of the bicycle's movement is defined as "forward" and "rear," thus confirming the positions of the "front wheel," "rear wheel," "front of the crossbeam 11," and "rear of the crossbeam 11." The connection and arrangement of the frame 1, seat 3, handlebars 4, front wheel 5 and rear wheel 6, as well as the necessary pedals and steering mechanisms, are all existing technologies and will not be described in detail here.

[0042] The frame 1, especially the crossbeam 11 of the frame 1, serves as the mounting base for the truck bed 2. The truck bed 2 is mounted on the crossbeam 11 of the frame 1 and is located between the front wheel 5 and the first support 12. In this embodiment, the truck bed 2 is used to carry a child and includes a first baffle 21 and a second baffle 22 arranged opposite each other. A base plate 23 is connected between the bottoms of the first baffle 21 and the second baffle 22, and the base plate 23 spans across the crossbeam 11. The first baffle 21, the second baffle 22, and the base plate 23 can all be composed of a single plate or multiple plates assembled together. A connecting rod 24 is connected between the first baffle 21 and the second baffle 22 on the side near the front wheel 5. The connecting rod 24 can be used for gripping. Alternatively, connecting rods 24 can be respectively provided on the top of the first baffle 21 and the second baffle 22, which can also be used for gripping. Preferably, the cross-section of the connecting rod 24 is circular.

[0043] The basket 2 is detachably mounted to the crossbeam 11 of the frame 1. For this purpose, the bicycle also includes a first mounting bracket 71, a second mounting bracket 72, a mounting base 73, and a locking mechanism 74. The first mounting bracket 71 includes a first bracket body 711, which is preferably elongated and abuts against the upper surface of the crossbeam 11, approximately perpendicular to it. A first groove 712 is formed on the first bracket body 711. The cross-section of the first groove 712 (in the normal installation state, the vertical cross-section extending between the front wheel 5 and the rear wheel 6, see...) Figure 6 The plane S1 in the middle (which serves as a cross-section) is approximately inverted T-shaped. That is, the first groove 712 includes a first groove portion 7121 and a second groove portion 7122 arranged vertically and communicating with each other. The width of the first groove portion 7121 is smaller than the width of the second groove portion 7122 (width refers to the dimension along the direction from the front wheel 5 to the rear wheel 6, see [reference]). Figure 6 (The dimension is shown in the direction of arrow Z in the image). The first groove 7121 of the first groove 712 can penetrate through the top of the first support body 711. A second groove 713 is also formed on the first support body 711, which is adjacent to and communicates with the first groove 712. The first groove 712 and the second groove 713 are arranged side by side along the length of the first support body 711, and the width of the second groove 713 is greater than the width of the first groove 712.

[0044] The bottom of the bracket plate 711 has a first mounting hole 714. The mounting base 73 includes a first connecting part 731, a second connecting part 732, and a third connecting part 733 arranged sequentially from top to bottom. The three connecting parts can be integrally formed. The first connecting part 731 can be inserted upward into the bottom plate 23 of the cart 2, defining the horizontal position of the bottom plate 23. A positioning hole 231 can be provided on the bottom plate 23 to facilitate engagement with the first connecting part 731. Alternatively, the bottom plate 23 and the first connecting part 731 can be fixed by other methods, such as adhesive. The second connecting part 732 is larger than the first connecting part 731. The second connecting part 732 can abut against the bottom surface of the bottom plate 23 of the cart 2 outside the edge of the positioning hole 231, thereby defining the downward limit position of the cart 2. When a child is carried in the cart 2, the weight of the child will press the cart 2 downward, thus preventing the cart 2 from moving upward and detaching from the mounting base 73. The third connecting portion 733 is larger than the second connecting portion 732, allowing it to be confined within the second groove 7122 of the first groove 712, thus preventing the mounting base 73 from detaching upwards from the first mounting bracket 71. Since the width of the second groove 7122 is greater than the first groove 7121, its top has opposing walls that abut against the third connecting portion 733, defining its position. The third connecting portion 733 is smaller than the second groove 713, allowing it to detach upwards from the second groove 713 from the first mounting bracket 71, and also allowing the mounting base 73 to be inserted into the first mounting bracket 71 from the second groove 713 and slide into the first groove 712. The bottom surface of the third connecting portion 733 is recessed upwards to form a locking hole 7331. When the locking hole 7331 and the first mounting hole 714 are aligned, the mounting base 73 slides to the mounting position, and the sliding direction of the mounting base 73 is the length direction of the first bracket body 711. Alternatively, the shape of the first groove 7121, the second groove 7122, and the mounting base 73 can be designed so that the mounting base 73 can be confined in the first groove 7121 and can be disengaged from the second groove 7122, without being limited by the size specifications.

[0045] To facilitate the installation of the mounting base 73, both the first connecting portion 731 and the second connecting portion 732 are cylindrical, thus eliminating the need to set a specific installation angle for the mounting base 73. The third connecting portion 733 may also be approximately cylindrical at the top, and the dimensions of each of the aforementioned connecting portions are their cross-sectional outer diameters. To facilitate determining the installation position of the mounting base 73 and to prevent the mounting base 73 from sliding relative to the first mounting bracket 71 after reaching the installation position, the first groove portion 7121 of the first groove 712 has arc-shaped protrusions on opposite sides (groove side portions 7123) along the width direction of the first mounting bracket 71, respectively, in a direction away from each other, thereby adapting to the outer periphery of the second connecting portion 732, so that the second connecting portion 732 engages within the first groove portion 7121.

[0046] In this embodiment, preferably, there are two first mounting brackets 71, and each first mounting bracket 71 has a first groove 712 and a second groove 713 at both ends along its length. The two grooves at both ends are arranged in the same way, that is, the first groove 712 at each end is located on the same side of the second groove 713, such as... Figure 6 As shown, each first groove 712 is located to the left of the adjacent second groove 713. Two first mounting brackets 71 are arranged at intervals along the front-rear direction from the front wheel 5 to the rear wheel 6. The first mounting brackets 71 span the crossbeam 11, and mounting seats 73 are respectively provided on both sides of the crossbeam 11, which makes the installation of the truck bed 2 relative to the crossbeam 11 more stable.

[0047] The second mounting bracket 72 can be disposed on the side of the crossbeam 11. Each first mounting bracket 71 corresponds to two second mounting brackets 72, and each second mounting bracket 72 corresponds to a set of grooves of the first mounting bracket 71 (the first groove 712 and the second groove 713 form a set of grooves). The first mounting bracket 71 and the second mounting bracket 72 can be fixed by screws. The second mounting bracket 72 includes a second bracket body 721. One end of the second bracket body 721 can abut against the side of the crossbeam 11. The second bracket body 721 can extend downward on opposite sides along the width direction of the first mounting bracket 71 to form lugs 722. The bottom of the lugs 722 can abut against the protrusions 111 on the side of the crossbeam 11. The end of the second bracket body 721 away from the crossbeam 11 can be fixed with screws to the first bracket body 711 of the first mounting bracket 71, thereby fixing the positions of the first mounting bracket 71 and the second mounting bracket 72 relative to the crossbeam 11. The second bracket body 721 is provided with a second mounting hole 723, which is opposite to the first mounting hole 714. A first mounting bracket 71 and two second mounting brackets 72 can thus constitute a set of mounting bracket assemblies.

[0048] The locking mechanism 74 includes a first sleeve 741, a second sleeve 742, a pin 743, and an elastic element 744. The first sleeve 741 includes a first cylindrical body 7411, a first slot 7412 formed within the first cylindrical body 7411, and a second slot 7413 formed within the first cylindrical body 7411. The first cylindrical body 7411 may be cylindrical. The second slot 7413 is located above the first slot 7412, and the two slots are interconnected. The second slot 7413 penetrates through the top of the first sleeve 741. (The cross-section of the first slot 7412 can be seen in the image.) Figure 9As shown in plane S2 (the horizontal cross-section in the normal installation state) the shape is non-circular. Non-circular refers to shapes other than circles, such as polygons, ellipses, sectors, arcs, or irregular shapes. In this embodiment, the cross-section of the first slot 7412 is hexagonal. A radially outward flange 7414 can be formed at the bottom of the first cylinder 7411 to facilitate gripping on the flange 7414 for operation of the first sleeve 741.

[0049] The second sleeve 742 includes a second cylindrical body 7421 and a positioning post 7422 formed on the top of the second cylindrical body 7421. The positioning post 7422 is engaged in the first mounting hole 714 of the first mounting bracket 71, thereby fixing the relative positions of the first mounting bracket 71 and the second sleeve 742. The second cylindrical body 7421 is located below the first mounting bracket 71. The second cylindrical body 7421 can be inserted into the first slot 7412 and the second slot 7413 of the first sleeve 741, and the first sleeve 741 can slide up and down relative to the second sleeve 742. The external shape of the second cylindrical body 7421 is adapted to the first slot 7412, that is, the outline of the cross-section is consistent with the outline of the first slot 7412, and it is also non-circular, hexagonal in this embodiment. The second cylindrical body 7421 is only slightly smaller than the first slot 7412, so that the second cylindrical body 7421 and the first slot 7412 have sufficient movement clearance for sliding relative to the first sleeve 741. The second sleeve 742 also includes a through hole 7423 that passes through the second cylinder 7421 and the positioning post 7422. The size and shape of the second slot 7413 allow the second sleeve 742 to pass freely, ensuring that the two can move relative to each other. The first cylinder 7411 of the first sleeve 741 can be inserted into the second mounting hole 723 of the second mounting bracket 72.

[0050] One end of the pin 743 is fixed to the bottom surface of the first slot 7412 of the first sleeve 741, and thus passes upward through the through hole 7423 of the second sleeve 742, extending upward out of the second sleeve 742 and into the locking hole 7331 of the mounting base 73. An elastic element 744 is used to maintain the upward movement tendency of the pin 743. Preferably, the elastic element 744 is a spring, sleeved on the outer periphery of the pin 743 and located within the through hole 7423 of the second sleeve 742. The upper and lower ends of the elastic element 744 abut against the pin 743 and the second sleeve 742, respectively. This can be achieved by forming radial protrusions on the outer periphery of the pin 743 and the inner wall of the through hole 7423; this is a conventional method of spring installation.

[0051] The following describes the installation method of the bicycle basket 2. The installation of other bicycle components is the same as existing technology and will not be repeated here. Before installing the bicycle basket 2, complete the installation of the following components: 1) Install the first mounting bracket 71 and the second mounting bracket 72, as described above; 2) Install the mounting seat 73 to the bottom of the bicycle basket 2; 3) Install the second sleeve 742 of the locking mechanism 74 to the first mounting bracket 71. Pull down the first sleeve 741, as shown in the previous section. Figures 11-13 This positions the second sleeve 742 above the top surface of the first slot 7412, and then rotates the first sleeve 741 by a certain angle. The direction of rotation can be found in [reference needed]. Figure 13 As indicated by arrow X, the first sleeve 741 rotates around the vertically extending axis in the normal installation state. Since the first sleeve 741 is fitted around the outer periphery of the second sleeve 742, and the second sleeve 742 is fixed, the axis of the first sleeve 741 will not shift during rotation. Since the cross-section of the first slot 7412 and the second cylinder 7421 is hexagonal, after the first sleeve 741 rotates relative to the second sleeve 742 by a certain angle, the corner of the second cylinder 7421 (the corner of the hexagon) can correspond to the edge of the top surface of the first slot 7412 (the edge of the hexagon). This prevents the second sleeve 742 from being inserted downward into the first slot 7412. Instead, the bottom surface of the second cylinder 7421 abuts against the top surface of the first slot 7412. At this time, the elastic element 744 is in a compressed state, and the pin 743 retracts into the second sleeve 742.

[0052] Then, install the truck bed 2. Place the truck bed 2 on the crossbeam 11 of the frame 1, aligning the mounting base 73 with the second groove 713 of the first mounting bracket 71. Insert the truck bed 2 downwards into the second groove 713. Then, move the truck bed 2 so that the mounting base 73 slides into the first groove 712. Then, rotate the first sleeve 741 again so that the edges and corners of the first slot 7412 and the second cylinder 7421 are aligned again (edge ​​to edge, corner to corner). The second cylinder 7421 no longer abuts against the top surface of the first slot 7412. Under the action of the elastic element 744, the first sleeve 741 and the pin 743 are pushed upwards, and the pin 743 is inserted into the locking hole 7331 of the mounting base 73, completing the installation of the truck bed 2. See [link to relevant documentation]. Figure 4 and Figure 5 .

[0053] When it is necessary to disassemble the truck bed 2, simply pull down the first sleeve 741 and rotate it a certain angle. See below. Figures 10-13 The locking mechanism 74 returns to the state before the truck bed 2 was installed. The truck bed 2 can be moved in the opposite direction to the direction during installation, so that the mounting seat 73 moves to the second groove 713. Then the truck bed 2 is lifted up to complete the disassembly of the truck bed 2.

[0054] When the cross-sections of the first slot 7412 and the second cylinder 7421 are other non-circular shapes, they can also be rotated at a certain angle to achieve contact. For example, if they are elliptical, the major axes of the two ellipses can be intersected.

[0055] In this invention, the first mounting bracket 71 and the second mounting bracket 72 are independent brackets, which facilitates manufacturing and assembly / disassembly with the crossbeam 11. Alternatively, the first mounting bracket 71 and the second mounting bracket 72 can be an integral piece. Alternatively, the first mounting bracket 71 and the second mounting bracket 72 can be an integral piece with the crossbeam 11. Alternatively, the first mounting bracket 71 and the second mounting bracket 72 can be omitted, and the locking mechanism 74 can be directly installed from bottom to top to the bottom of the crossbeam 11.

[0056] With the above-described installation structure of the present invention, the locking and unlocking of the truck bed 2 can be quickly achieved by simply pulling and rotating the first sleeve 741 without the need for tools. The truck bed 2 can be disassembled and assembled after the locking mechanism 74 is unlocked and the truck bed 2 is moved.

[0057] Example 2

[0058] See Figure 14 In this embodiment, the cargo box 2 is used for placing items, and for this purpose it may include a box body 25 with an open top and a cover plate 26 movably disposed at the open top of the box body 25. The box body 25 also includes a bottom plate 23 connected to the mounting base 73.
