Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a bicycle frame and a bicycle. Background Technology

[0002] Some bicycles (such as mountain bikes) are equipped with a rear shock absorber, primarily used to absorb bumps and impacts encountered by the rear wheel during riding, improving riding comfort and handling. When the rear wheel encounters an obstacle, the shock absorber compresses to absorb the impact. After passing the obstacle, the shock absorber rebounds.

[0003] In traditional technology, bicycles equipped with a rear shock absorber are always in a shock-absorbing state. When riding on a flat road, the pedaling force is absorbed by the shock absorber, thus consuming some energy and reducing the bicycle's riding speed. Utility Model Content

[0004] Therefore, it is necessary to provide a frame and bicycle that can improve upon the aforementioned problems.

[0005] A frame, comprising:

[0006] Front frame;

[0007] The rear frame is rotatably connected to the front frame.

[0008] A shock absorber is provided between the front frame and the rear frame, and extends and retracts to absorb shock when the rear frame rotates relative to the front frame.

[0009] The locking component is capable of switching between a locked state and a released state. When the locking component is in the locked state, it locks the rear frame to the front frame, restricting the rear frame from rotating relative to the front frame. When the locking component is in the released state, it allows the rear frame to rotate relative to the front frame.

[0010] In one embodiment, the locking component includes:

[0011] The connector is movably connected to at least one of the front frame and the rear frame in the extension and retraction direction of the shock absorber;

[0012] The locking component, when in the locked state, restricts the movement of the connector relative to the front frame and the rear frame along the telescopic direction, thereby restricting the rotation of the rear frame relative to the front frame; when in the released state, the locking component allows the connector to move relative to the front frame and / or the rear frame along the telescopic direction, thereby allowing the rear frame to rotate relative to the front frame.

[0013] In one embodiment, the connector is fixedly connected to the front frame and movably connected to the rear frame;

[0014] The locking member is movably connected to the rear frame and is movable relative to the rear frame to switch between a locked position (where the locking member is in the locked state) and a released position (where the locking member is in the released state). When the locking member is in the locked position, it is located on the movement path of the connecting member relative to the rear frame to restrict the movement of the connecting member relative to the rear frame. When the locking member is in the released position, it avoids the connecting member, allowing the connecting member to move relative to the rear frame.

[0015] In one embodiment, the rear frame includes a connecting plate, the connecting plate having a first through hole extending along the telescopic direction, and the connector being movably inserted into the first through hole;

[0016] The locking element is rotatably or slidably connected to the connecting plate to switch between the locked position and the released position.

[0017] In one embodiment, the rear frame further includes a baffle connected to the connecting plate, and the locking member is mounted on the baffle;

[0018] The baffle has a second through hole that extends through the telescopic direction, and the second through hole is directly opposite the first through hole.

[0019] When the locking member is in the locked position, the locking member abuts against the end of the connector away from the front frame; when the locking member is in the released position, the connector can move relative to the rear frame to pass through the second through hole.

[0020] In one embodiment, the locking assembly further includes a reset member connected to the locking member and the rear frame.

[0021] When the locking member moves from one of the released position and the locked position to the other, the reset member elastically deforms to store energy for resetting the locking member.

[0022] In one embodiment, the shock absorber is fitted over the connector.

[0023] In one embodiment, the shock absorber is a rubber component or a spring.

[0024] A bicycle, comprising a front wheel, a rear wheel, and a frame as described above;

[0025] The front wheel is mounted on the front frame, and the rear wheel is mounted on the rear frame.

[0026] In one embodiment, the bicycle further includes handlebars connected to the front frame; the locking assembly is mounted on the front frame and / or the rear frame.

[0027] The bicycle also includes an operating cable and an operating handle, the operating handle being mounted on the handlebars, one end of the operating cable being connected to the operating handle, and the other end being connected to at least a portion of the locking assembly; operating the operating handle controls the operating cable, and the operating cable causes the locking assembly to switch from one of the released state and the locked state to the other.

[0028] In the aforementioned frame and bicycle, when the locking mechanism is locked, it restricts the rear frame's rotation relative to the front frame. Since the rear frame cannot rotate relative to the front frame, the shock absorber cannot be compressed, and the shock absorber does not perform its damping function; at this time, the frame is in a non-dampened state (hardtail state). When the locking mechanism is released, it allows the rear frame to rotate relative to the front frame. This rotation allows the rear frame to work together to compress the shock absorber, enabling it to perform its damping function; at this time, the frame is in a damped state (softtail state). Thus, under the action of the locking mechanism, the frame can switch between damped and non-dampened states. When riding on bumpy or impact-prone surfaces, the locking mechanism is released, and the frame provides rear damping. When riding on flat surfaces, the locking mechanism is locked, and the frame does not provide rear damping; pedaling force is not absorbed by the shock absorber, reducing energy loss and ensuring riding speed.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0044] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0048] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0049] See Figure 1 One embodiment of this application provides a vehicle frame 100, including a front frame 10, a rear frame 20, and a shock absorber 30. The front frame 10 and the rear frame 20 are rotatably connected, and the shock absorber 30 is disposed between the front frame 10 and the rear frame 20, extending and contracting to absorb shock when the rear frame 20 rotates relative to the front frame 10. The front frame 10 is used to mount the front wheel 200, and the rear frame 20 is used to mount the rear wheel 300. When the rear wheel 300 encounters an obstacle, the rear frame 20 rotates relative to the front frame 10, and the shock absorber 30 disposed between the front frame 10 and the rear frame 20 is compressed to absorb the impact force. After passing the obstacle, the shock absorber 30 rebounds.

[0050] Optionally, see Figures 1-3The front frame 10 includes a head tube 11, a fork assembly 12, a main beam 13, a bottom bracket 14, a bottom bracket 15, and a first connecting assembly 16. The two ends of the main beam 13 are connected to the head tube 11 and the bottom bracket 14, respectively. The fork assembly 12 is connected to the head tube 11. One end of the bottom bracket 14 is used to mount the saddle. The bottom bracket 15 and the first connecting assembly 16 are both connected to the end of the bottom bracket 14 furthest from the saddle. The rear frame 20 includes an upper fork assembly 21, a lower fork assembly 22, and a second connecting assembly 23. The upper fork assembly 21 and the lower fork assembly 22 meet at one end for mounting the rear wheel 300. The second connecting assembly 23 is connected to the end of the upper fork assembly 21 and the lower fork assembly 22 furthest from the rear wheel 300. Furthermore, the upper fork assembly 21, the lower fork assembly 22, and the second connecting assembly 23 are connected in a roughly triangular structure. This triangular structure provides good stability and improves the rigidity of the frame 100. The frame 100 also includes a pivot 40, and one end of the second connecting assembly 23 connected to the lower fork assembly 22 is rotatably connected to the first connecting assembly 16 via the pivot 40. That is, the front frame 10 and the rear frame 20 are rotatably connected via the pivot 40. The shock absorber 30 is located between the end of the second connecting assembly 23 connected to the upper fork assembly 21 and the center tube 14.

[0051] In the above configuration, when the rear wheel 300 encounters an obstacle, the obstacle applies a force to the rear wheel 300. The rear wheel 300 then drives the upper fork assembly 21, the lower fork assembly 22, and the second connecting assembly 23 in conjunction. The second connecting assembly 23 rotates relative to the first connecting assembly 16 via the pivot 40. When the second connecting assembly 23 rotates relative to the first connecting assembly 16, the shock absorber 30 is compressed to absorb the shock. When the obstacle is passed, the shock absorber 30 rebounds, the second connecting assembly 23 rotates relative to the first connecting assembly 16 via the pivot 40, and the rear wheel 300 returns to its original position.

[0052] It should be noted that the front frame 10 is used to mount the front wheel 200, and the rear frame 20 is used to mount the rear wheel 300. The above embodiments describe the specific implementation of the front frame 10 and the rear frame 20. However, in other embodiments, the front frame 10 and the rear frame 20 can be modified accordingly to adapt to actual usage requirements, and such modifications are also included within the scope of protection of this application. Furthermore, the above embodiments describe the front frame 10 and the rear frame 20 as being rotatably connected by a pivot 40. However, in other embodiments, the frame 100 can also be provided with multiple pivots 40 to achieve the rotatable connection between the front frame 10 and the rear frame 20. Additionally, in other embodiments, the position of the shock absorber 30 can be changed according to actual needs, as long as the shock absorption effect is achieved.

[0053] In some embodiments, the shock absorber 30 can be a rubber component or a spring. Since rubber components and springs have good elasticity, selecting a rubber component or a spring for the shock absorber 30 can improve the shock absorption effect of the shock absorber 30.

[0054] See Figure 4 The frame 100 also includes a locking assembly 50, which has a locked state and an unlocked state, and is capable of switching between the locked and unlocked states. When the locking assembly 50 is in the locked state, it locks the rear frame 20 and the front frame 10, restricting the rear frame 20 from rotating relative to the front frame 10. When the locking assembly 50 is in the unlocked state, it allows the rear frame 20 to rotate relative to the front frame 10.

[0055] With the above configuration, when the locking component 50 is in the locked state, it restricts the rear frame 20 from rotating relative to the front frame 10. Since the rear frame 20 cannot rotate relative to the front frame 10, the shock absorber 30 cannot be compressed, and the shock absorber 30 does not perform its shock absorption function. At this time, the frame 100 is in an undamped state (hardtail state). When the locking component 50 is in the released state, it allows the rear frame 20 to rotate relative to the front frame 10. When the rear frame 20 rotates relative to the front frame 10, it can cooperate to compress the shock absorber 30, and the shock absorber 30 can perform its shock absorption function. At this time, the frame 100 is in a damped state (softtail state). Thus, under the action of the locking component 50, the frame 100 can switch between a shock-absorbing state and a non-shock-absorbing state. When riding on bumpy and impactful roads, the locking component 50 is in the released state, and the frame 100 has a rear shock absorption effect. When riding on flat roads, the locking component 50 is in the locked state, and the frame 100 does not have a rear shock absorption effect. The pedaling force is not absorbed by the shock absorber 30, reducing energy consumption and ensuring the riding speed of the bicycle 1000.

[0056] In some embodiments, see Figure 4 And see Figures 5-7 The locking assembly 50 includes a connector 51 and a locking member 52. In the extension / retraction direction X of the shock absorber 30, the connector 51 is movably connected to at least one of the front frame 10 and the rear frame 20. When the locking assembly 50 is locked, the locking member 52 restricts the movement of the connector 51 relative to the front frame 10 and the rear frame 20 in the extension / retraction direction X, thereby indirectly restricting the rotation of the rear frame 20 relative to the front frame 10, so that the frame 100 is in a non-damped state. When the locking assembly 50 is released, the locking assembly 50 allows the connector 51 to move relative to the front frame 10 and / or the rear frame 20, thereby indirectly allowing the rear frame 20 to move relative to the front frame 10 in the extension / retraction direction X, so that the frame 100 is in a damped state.

[0057] It is understood that in other embodiments, the locking component 50 may also adopt other configurations, as long as they enable the frame 100 to switch between a shock-absorbing state and a non-shock-absorbing state. For example, the locking component 50 may omit the connecting member 51 and only include the locking member 52, through which the frame 100 can switch between a shock-absorbing state and a non-shock-absorbing state. Optionally, the locking member 52 may be a detachable fixing screw mounted on the front frame 10 and the rear frame 20.

[0058] Optionally, see Figure 8 The shock absorber 30 is fitted onto the connecting member 51. When the connecting member 51 moves relative to the front frame 10 and / or the rear frame 20 along the extension / retraction direction X, the front frame 10 and the rear frame 20 cooperate to compress the shock absorber 30, and the shock absorber 30 provides a shock absorption effect. This improves the assembly compactness of the frame 100. Of course, in some other embodiments, there may be no direct connection between the shock absorber 30 and the connecting member 51.

[0059] In some embodiments, the connector 51 has a columnar structure to facilitate the mounting of the shock absorber 30. It is conceivable that in other embodiments, the shape of the connector 51 is not limited.

[0060] Furthermore, the connector 51 is fixedly connected to the front frame 10 and movably connected to the rear frame 20. The locking member 52 is movably connected to the rear frame 20 and is movable relative to the rear frame 20 to switch between a locked position and a released position. When the locking member 52 is in the locked position, the locking assembly 50 is in a locked state. When the locking member 52 is in the released position, the locking assembly 50 is in a released state. (Continue reading...) Figure 8 When the locking element 52 is in the locked position, it is positioned on the movement path of the connecting element 51 relative to the rear frame 20, thus restricting the movement of the connecting element 51 relative to the rear frame 20. (See also...) Figure 9 When the locking member 52 is in the released position, the locking member 52 avoids the connecting member 51, allowing it to move relative to the rear frame 20.

[0061] The above setup allows for easy switching between the locked and released states of the locking component 50 by simply switching the locking element 52 between the locked and released positions. This, in turn, enables the frame 100 to switch between a non-shock-absorbing state and a shock-absorbing state.

[0062] Continue reading Figures 8-10The second connecting assembly 23 includes a connecting plate 231, which has a first through hole 232 extending along the telescopic direction X. The connecting member 51 is movably inserted through the first through hole 232. A locking member 52 is rotatably connected to the connecting plate 231 to switch between a locked position and a released position. The first through hole 232 on the connecting plate 231 facilitates the movable connection between the connecting member 51 and the rear frame 20 along the telescopic direction X. When the locking member 52 is in the locked position, it restricts the movement of the connecting member 51 in the first through hole 232; when the locking member 52 is in the released state, it allows the connecting member 51 to move in the first through hole 232.

[0063] The rear frame 20 also includes a baffle 233, which is connected to the connecting plate 231. A locking element 52 is installed on the baffle 233. A second through hole 234 is provided through the baffle 233 along the telescopic direction X, and the second through hole 234 is directly opposite the first through hole 232. (Continue reading) Figure 8 When the locking element 52 is in the locked position, the locking element 52 abuts against the end of the connecting element 51 away from the front frame 10. (Continue reading...) Figure 9 and Figure 10 When the locking member 52 is in the released position, the connecting member 51 moves relative to the rear frame 20 to pass through the second through hole 234. The baffle 233 is provided to facilitate the installation of the locking member 52. When rear shock absorption is required, the connecting member 51 can pass through the second through hole 234 on the baffle 233, and the second through hole 234 serves to avoid the connecting member 51.

[0064] See Figure 11 and Figure 12 The locking member 52 is slidably connected to the baffle 233 to switch between a locked position and a released position. Optionally, the baffle 233 is provided with a slide groove, and a portion of the locking member 52 extends into the slide groove to slide within the slide groove, thereby switching the locking member 52 between the locked position and the released position.

[0065] In some embodiments, see further reference. Figure 4 The locking assembly 50 also includes a reset member 53, which connects the locking member 52 and the rear frame 20. When the locking member 52 moves from one of the released position and the locked position to the other, the reset member 53 elastically deforms to store energy for resetting the locking member 52. The reset member 53 is provided to facilitate automatic reset of the locking member 52 from the locked position to the released position or to facilitate automatic reset of the locking member 52 from the released position to the locked position. Optionally, the reset member 53 is a spring.

[0066] Continue reading Figure 1Another embodiment of this application also provides a bicycle 1000, which includes a front wheel 200, a rear wheel 300, and the aforementioned frame 100. Since the frame 100 has beneficial effects, the bicycle 1000 including the frame 100 has the same beneficial effects, which will not be described in detail here.

[0067] Furthermore, the bicycle 1000 also includes a handlebar 400, which is connected to the front fork assembly 12 via the head tube 11 of the front frame 10. The direction of travel of the bicycle 1000 can be controlled by manipulating the handlebar 400. A locking assembly 50 is mounted on the front frame 10 and / or the rear frame 20. The bicycle 1000 also includes an operating lever 500 and an operating cable 600. The operating lever 500 is mounted on the handlebar 400, and one end of the operating cable 600 is connected to the operating lever 500, while the other end is connected to at least a portion of the locking assembly 50. Operating the operating lever 500 controls the operating cable 600, which in turn switches the locking assembly 50 from a released state to a locked state. Specifically, the other end of the operating cable 600 is connected to a locking member 52, which switches the locking member 52 from one released position to the other, thereby switching the locking assembly 50 from one released state to the other. Thus, when a rider rides bicycle 1000, the locking component 50 can be switched from the released state to the locked state or from the locked state to the released state by operating the operating handle 500, which means that the frame 100 can be switched between the shock-absorbing state and the non-shock-absorbing state.

[0068] It should be noted that whether the operation handle 500 switches the locking component 50 from the released state to the locked state or from the locked state to the released state is set according to the needs.

[0069] It is conceivable that in other embodiments, the bicycle 1000 may omit the operating handle 500 and the operating line 600, and instead be operated directly by hand or foot to switch the locking member 52 between the released and locked positions. Alternatively, the operating line 600 may be shorter, and the switching of the locking member 52 between the released and locked positions may be achieved by manually operating the operating line 600.

[0070] The locking assembly 50 also includes a reset member 53, which can reset the locking member 52. When the locking member 52 is switched from the released position to the locked position via the operating handle 500, the reset member 53 can reset the locking member 52 from the locked position to the released position. When the locking member 52 is switched from the locked position to the released position via the operating handle 500, the reset member 53 can reset the locking member 52 from the released position to the locked position.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0072] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
