Description

Technical Field

[0001] The present application relates to the field of bicycles, and in particular to a bicycle frame with a connecting rod shock absorbing system. Background Art

[0002] Bicycles can be divided into electric-assisted bicycles and ordinary human-powered bicycles according to their power sources. There are various ways to reduce shock, including front fork shock, frame shock, seat tube shock and other methods.

[0003] In the related art, a bicycle with a suspension frame has a shock absorber installed in the middle part of the frame, and the front and rear triangles of the frame are designed as two independent parts with a pivot point, which are interconnected by a connecting rod group to form a suspension structure. The connecting rod group and the shock absorber are responsible for buffering impact and shock absorption, thereby producing a shock absorption effect during riding.

[0004] Regarding the above-mentioned related technologies, there is a defect that during the shock absorption process, the rear triangle movement of the frame causes the position of the rear wheel axis to change, and the horizontal displacement of the rear wheel axis is large, which makes the rider's center of gravity unstable, thereby causing unsafe riding during the shock absorption process. Summary of the invention

[0005] In order to make riding safer during the shock absorption process, the present application provides a bicycle frame with a connecting rod shock absorption system.

[0006] The bicycle frame with a connecting rod shock absorbing system provided in the present application adopts the following technical solution: A bicycle frame with a connecting rod shock absorbing system, comprising: The front tripod is slidably provided with a vertical shock-absorbing slide seat, and a plurality of the vertical shock-absorbing slide seats are distributed along the vertical direction; rear tripod; An intermediate connecting rod, one end of which is hinged to the rear tripod, and the other end of which is hinged to one of the vertical shock-absorbing slide seats; A vertical resetting elastic member connected to the vertical shock-absorbing sliding seat; A swing reset elastic member connected to the intermediate connecting rod; A vertical control assembly connected to the vertical damping slide and used to control whether the vertical damping slide slides relative to the front tripod; The swing control assembly is connected to the hinge between the intermediate connecting rod and the vertical damping slide, and is used to control whether the intermediate connecting rod rotates relative to the vertical damping slide.

[0007] By adopting the above technical solution, when encountering small bumps, the swing control component releases the lock between the middle connecting rod and the vertical shock-absorbing slide seat, so that the rear tripod and the front tripod can rotate relative to each other, so that the shock can be reduced by hinged rotation. When encountering large bumps, the vertical control component releases the lock of the vertical shock-absorbing slide seat, so that the rear tripod and the front tripod can slide vertically relative to each other, so that the shock can be reduced by sliding up and down. Therefore, during the shock absorption process, the axis of the rear wheel will not produce a large horizontal displacement, so that the rider's center of gravity is more stable, thereby making riding safer during the shock absorption process.

[0008] Preferably, a gyro sensor and a visual camera are provided at an end of the front tripod away from the rear tripod.

[0009] By adopting the above technical solution, firstly, the gyroscope sensor can be used to quickly determine whether the bicycle encounters a small or large bump during riding, so that the bicycle frame can be quickly switched to the corresponding shock absorption mode; secondly, the visual camera can be used to pre-determine the type of bump, so that the bicycle frame can also be quickly switched to the corresponding shock absorption mode.

[0010] Preferably, the intermediate connecting rod is an electric cylinder structure, and a plurality of the intermediate connecting rods are arranged in a non-parallel manner.

[0011] By adopting the above technical solution, the distance between the front triangle and the rear triangle in the horizontal direction can be changed, so the wheelbase of the bicycle can be changed to adapt to narrow roads or non-narrow roads.

[0012] Preferably, the front tripod is provided with a vertical shock-absorbing track, and the vertical shock-absorbing track is provided with a track slot, the cross-sectional area of ​​the track slot close to the slot opening is larger than that of the track slot close to the bottom, and the track slot is provided for the vertical shock-absorbing slide to slide; the vertical control component includes a vertical clamping block, a guide rod and a locking electromagnet, the vertical clamping block is a T-shaped block structure, the vertical clamping blocks are distributed at both ends in the length direction of the track slot, the long end of the vertical clamping block is passed through the track slot and abuts against the vertical shock-absorbing slide, one end of the guide rod is connected to one of the short ends of the vertical clamping block, and the other end is passed through the vertical shock-absorbing track to form a closing slot, the locking electromagnet is arranged in the closing slot, and the locking electromagnet magnetically attracts the guide rod to make the two vertical clamping blocks close to each other.

[0013] By adopting the above technical solution, after the locking electromagnet is started, the guide rod can be magnetically attracted to bring the two vertical clamps closer together until the side of the two vertical clamps close to each other abuts against the vertical shock-absorbing slide, thereby locking the vertical shock-absorbing slide. Similarly, if unlocking is required, it is only necessary to turn off the locking electromagnet.

[0014] Preferably, a vertical adjustment spring is connected between the guide rod and the locking electromagnet.

[0015] By adopting the above technical solution, firstly, when the vertical shock-absorbing slide hits the vertical clamp, the vertical clamps will move away from each other. At this time, the elastic force of the vertical adjustment spring also weakens the kinetic energy of the vertical shock-absorbing slide, thereby accelerating the resetting of the vertical shock-absorbing slide and shortening the shock absorption time, thereby allowing the rider to better control the bicycle; secondly, since the relative movement of the front tripod and the rear tripod will cause certain operating difficulties for the rider, the distance between the two vertical clamps can be adjusted by means of the elastic force of the vertical adjustment spring and the magnetic force of the locking electromagnet, so the movement stroke of the vertical shock-absorbing slide can be changed, thereby changing the effective amplitude of the up and down sliding shock absorption, and then the adaptability of the shock absorption amplitude can be changed according to different riding scenarios.

[0016] Preferably, the swing control assembly includes a locking block, a swing clamping block, a closing spring and an unlocking electromagnet, the locking block is connected to the intermediate connecting rod, and the locking block and the intermediate connecting rod are coaxially arranged at the hinge between the vertical shock-absorbing slide; the swing clamping block is slidably arranged on the vertical shock-absorbing slide, and two swing clamping blocks clamp and limit one locking block; one end of the closing spring is connected to the vertical shock-absorbing slide, and the other end is connected to the swing clamping block; the unlocking electromagnet is arranged on the vertical shock-absorbing slide, and the unlocking electromagnet magnetically attracts the swing clamping block.

[0017] By adopting the above technical solution, when the unlocking electromagnet is not activated, the closing spring will allow the two swinging clamps to clamp the locking block to limit the rotation of the middle connecting rod, and when the unlocking electromagnet is activated, the swinging clamps will separate to release the restriction on the rotation of the middle connecting rod.

[0018] Preferably, the locking block is in the shape of a thin plate, and the locking block completely separates the two swing clamping blocks, so that the clamping force applied by the swing clamping block to the locking block forms a torque for causing the locking block to perform reset rotation.

[0019] By adopting the above technical solution, firstly, when the unlocking electromagnet is not activated, the swing clamp can clamp the locking block under the action of the closing spring to make the middle connecting rod do a reset swing, so the closing spring can accelerate the reset rotation of the middle connecting rod and shorten the shock absorption time, thereby allowing the rider to better control the bicycle; secondly, under the action of the unlocking electromagnet, the distance between the two swing clamps can be changed. At the same time, because the locking block completely separates the two swing clamps, the locking block will collide with the swing clamp during the swinging of the middle connecting rod to form a restriction on the swinging amplitude of the middle connecting rod, thereby changing the effective amplitude of the articulated rotation shock absorption, and then the shock absorption amplitude can be adaptively changed according to different riding scenarios.

[0020] Preferably, the swing clamp block and the locking block are in arc-shaped abutment with each other.

[0021] By adopting the above technical solution, when the unlocking electromagnet is not activated and the swing clamp completely clamps the locking block, the friction between the locking block and the swing clamp will not be very large. In the case of high-speed riding and sudden bumps, the locking block can also allow the swing clamp to open, so that the minimum amplitude of articulated rotation shock absorption can be formed, so as to avoid the buffer structure between the rear tripod and the front tripod from being damaged while maintaining riding stability.

[0022] Preferably, a locking rod is slidably penetrated by one of the swing clamps, the locking rod penetrates the center of the locking block, the locking rod is adsorbed by the unlocking electromagnet, a through-rod spring is arranged between the locking rod and the swing clamp, and the ability of the through-rod spring to resist deformation is less than the ability of the closing spring to resist deformation.

[0023] By adopting the above technical solution, during downhill high-speed riding, it is necessary to completely restrict the swing of the intermediate link, which can be achieved with the help of the cooperation between the lock rod and the lock block. In addition, the unlocking electromagnet is activated but the strength of the magnetic field can only allow the lock rod to separate from the lock block. However, when the swing clamp still holds the lock block, the minimum amplitude of articulated rotation shock absorption can still be formed.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When encountering a small bump, the swing control assembly releases the lock between the middle link and the vertical shock-absorbing slide seat, so that the rear tripod and the front tripod rotate relative to each other, so that the shock can be reduced by hinged rotation. When encountering a large bump, the vertical control assembly releases the lock of the vertical shock-absorbing slide seat, so that the rear tripod and the front tripod slide relative to each other vertically, so that the shock can be reduced by sliding up and down. Therefore, during the shock absorption process, the axis of the rear wheel will not have a large horizontal displacement, so that the rider's center of gravity is more stable, so that riding can be safer during the shock absorption process; 2. First, the gyroscope sensor can be used to quickly determine whether the bicycle encounters small or large bumps during riding, so that the bicycle frame can be quickly switched to the corresponding shock absorption mode; second, the visual camera can be used to pre-determine the type of bumps, so that the bicycle frame can also be quickly switched to the corresponding shock absorption mode.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a bicycle frame with a connecting rod shock absorbing system.

[0031] Reference Figure 1 and Figure 2 The bicycle frame with a connecting rod shock absorbing system comprises a front tripod 1, a rear tripod 2, an intermediate connecting rod 3, a vertical reset elastic member, a swing reset elastic member, a vertical control assembly 4 and a swing control assembly 5. The front tripod 1 is slidably provided with a vertical shock absorbing slide 11, and a plurality of vertical shock absorbing slides 11 are distributed in the vertical direction; one end of the intermediate connecting rod 3 is hinged to the rear tripod 2, and the other end is hinged to a vertical shock absorbing slide 11; the vertical reset elastic member is built into the front tripod 1 and connected to the vertical shock absorbing slide 11 to weaken the sliding kinetic energy transmitted to the vertical shock absorbing slide 11 by vibration, and to reset the vertical shock absorbing slide 11 to an initial position, so that up and down sliding shock absorption can be realized; the swing reset elastic member is connected to the intermediate connecting rod 3 to weaken the swing kinetic energy transmitted to the intermediate connecting rod 3 by vibration, and to reset the intermediate connecting rod 3 to an initial posture, so that hinged rotation shock absorption can be realized.

[0032] Reference Figure 1 and Figure 2The vertical control component 4 is connected to the vertical shock-absorbing slide 11, which can control whether the vertical shock-absorbing slide 11 slides relative to the front tripod 1; the swing control component 5 is connected to the hinge of the intermediate connecting rod 3 and the vertical shock-absorbing slide 11, which can control whether the intermediate connecting rod 3 rotates relative to the vertical shock-absorbing slide 11. When encountering a small bump, the swing control component 5 releases the lock between the intermediate connecting rod 3 and the vertical shock-absorbing slide 11, so that the rear tripod 2 and the front tripod 1 rotate relative to each other, so the hinged rotation method can be used for shock absorption. When encountering a large bump, the vertical control component 4 releases the lock of the vertical shock-absorbing slide 11, so that the rear tripod 2 and the front tripod 1 slide vertically relative to each other, so the up and down sliding method can be used for shock absorption. Therefore, during the shock absorption process, the axis of the rear wheel will not produce a large horizontal displacement, so that the center of gravity of the rider is more stable, thereby making riding safer during the shock absorption process.

[0033] Reference Figure 1 and Figure 2 In order to enable the bicycle to select the corresponding shock absorption mode more quickly during riding, a gyroscope sensor and a visual camera are arranged at the end of the front tripod 1 away from the rear tripod 2. First, the gyroscope sensor can be used to quickly determine whether a small bump or a large bump is encountered during riding, so that the bicycle frame can be quickly switched to the corresponding shock absorption mode; second, the visual camera can be used to pre-determine the type of bump, so that the bicycle frame can also be quickly switched to the corresponding shock absorption mode.

[0034] Reference Figure 1 and Figure 2 In order to adapt to narrow roads and non-narrow roads, the middle connecting rod 3 is an electric cylinder structure, and multiple middle connecting rods 3 are not arranged in parallel. The middle connecting rod 3 can be used to change the horizontal distance between the front triangle 1 and the rear triangle 2, so the wheelbase of the bicycle can be changed to adapt to narrow roads or non-narrow roads.

[0035] Reference Figure 1 and Figure 2 In order to realize the sliding connection between the vertical shock-absorbing slide 11 and the front tripod 1 through a simple structure, the front tripod 1 is provided with a vertical shock-absorbing track 12, and the vertical shock-absorbing track 12 is provided with a track slot 13. The part of the track slot 13 close to the slot opening has a larger cross-sectional area than the part close to the slot bottom. The track slot 13 is provided for the vertical shock-absorbing slide 11 to slide, so the vertical shock-absorbing slide 11 directly enters the track slot 13 from both ends of the track slot 13 to realize the installation of the vertical shock-absorbing slide 11.

[0036] Reference Figure 1 and Figure 2In order to make the startup and closing of the vertical control component 4 faster and smoother, the following settings are correspondingly arranged: the vertical control component 4 includes a vertical clamping block 41, a guide rod 42 and a locking electromagnet 43. The vertical clamping block 41 is a T-shaped block structure. The vertical clamping blocks 41 are distributed at both ends of the length direction of the track through groove 13. The long end of the vertical clamping block 41 is penetrated in the track through groove 13 and abuts against the vertical shock-absorbing slide 11. One end of the guide rod 42 is connected to one of the short ends of the vertical clamping block 41, and the other end is penetrated by the vertical shock-absorbing track 12 to form a closing groove 421. The locking electromagnet 43 is arranged in the closing groove 421. The locking electromagnet 43 magnetically attracts the guide rod 42 to make the two vertical clamping blocks 41 close to each other, so the restriction or release of the up and down sliding of the vertical shock-absorbing slide 11 can be achieved by opening and closing the locking electromagnet 43.

[0037] Reference Figure 1 and Figure 2 In order to make the startup and closing of the swing control component 5 faster and smoother, the following settings are correspondingly provided. The swing control component 5 includes a locking block 51, a swing clamping block 52, a closing spring 53 and an unlocking electromagnet 54. The locking block 51 is connected to the intermediate connecting rod 3. The locking block 51 and the intermediate connecting rod 3 are coaxially arranged at the hinge of the vertical shock-absorbing slide 11. The swing clamping block 52 is slidably arranged on the vertical shock-absorbing slide 11. The two swing clamping blocks 52 clamp one locking block 51 to limit the position. One end of the closing spring 53 is connected to the vertical shock-absorbing slide 11, and the other end is connected to the swing clamping block 52. The unlocking electromagnet 54 is arranged on the vertical shock-absorbing slide 11. The unlocking electromagnet 54 magnetically attracts the swing clamping block 52. The rotation of the intermediate connecting rod 3 can be restricted or released by the cooperation of the unlocking electromagnet 54 and the closing spring 53.

[0038] Reference Figure 1 and Figure 2 , allowing the rider to better control the bicycle is the key to safe riding, which can be considered from two angles. The first is to shorten the shock absorption time, that is, shorten the time for the vertical shock absorbing slide 11 to return to the initial position and the middle connecting rod 3 to return to the initial posture. The second is to select a suitable shock absorption amplitude according to the riding status.

[0039] Reference Figure 1 and Figure 2In the scenario of up and down sliding shock absorption, the following settings are correspondingly arranged: a vertical adjustment spring 431 is connected between the guide rod 42 and the locking electromagnet 43, and the two ends of the vertical adjustment spring 431 are respectively connected to the guide rod 42 and the locking electromagnet 43, so there are the following advantages: first, when the vertical shock absorption slide 11 hits the vertical clamping block 41, the vertical clamping blocks 41 will move away from each other. At this time, the elastic force of the vertical adjustment spring 431 also weakens the kinetic energy of the vertical shock absorption slide 11, thereby accelerating the reset of the vertical shock absorption slide 11 and shortening the shock absorption time, thereby allowing the rider to better control the bicycle; second, with the help of the elastic force of the vertical adjustment spring 431 and the magnetic force of the locking electromagnet 43, the distance between the two vertical clamping blocks 41 can be adjusted, so the movement stroke of the vertical shock absorption slide 11 can be changed, thereby changing the effective amplitude of the up and down sliding shock absorption, and then the adaptability of the shock absorption amplitude can be changed according to different riding scenarios.

[0040] Reference Figure 1 and Figure 2 In the case of articulated swing shock absorption, the following configuration is correspondingly adopted: the lock block 51 is in the shape of a thin plate, and the lock block 51 completely separates the two swing clamps 52, so the clamping force applied by the swing clamp 52 to the lock block 51 can form a torque for the lock block 51 to perform reset rotation, so the following advantages are correspondingly adopted: first, when the unlocking electromagnet 54 is not started, the swing clamp 52 can clamp the lock block 51 under the action of the closing spring 53, so that the intermediate connecting rod 3 performs reset swing, so the closing spring 53 can accelerate the reset rotation of the intermediate connecting rod 3 Secondly, under the action of the unlocking electromagnet 54, the distance between the two swinging clamps 52 can be changed. At the same time, because the locking block 51 completely separates the two swinging clamps 52, during the swinging of the middle connecting rod 3, the locking block 51 will collide with the swinging clamp 52 to limit the swinging amplitude of the middle connecting rod 3, thereby changing the effective amplitude of the articulated rotation shock absorption, and then the adaptability of the shock absorption amplitude can be changed according to different riding scenarios.

[0041] Reference Figure 1 and Figure 2In this embodiment, the vertical clamping block 41 is in contact with the vertical shock-absorbing slide 11 with a certain pressure. If there is a sudden bump during high-speed riding and there is no time to open the vertical clamping block 41, the vertical shock-absorbing slide 11 can still squeeze the vertical clamping block 41, so the vertical shock-absorbing buffer structure will not be damaged. At the same time, in order to make the articulated rotating shock absorption have a similar function, the swinging clamping block 52 and the locking block 51 are in contact with each other in an arc surface. Therefore, when the unlocking electromagnet 54 is not started and the swinging clamping block 52 completely clamps the locking block 51, the friction between the locking block 51 and the swinging clamping block 52 will not be very large. In the case of high-speed riding and sudden bumps, the locking block 51 can also open the swinging clamping block 52, so the smallest articulated shock absorption can be formed to avoid the buffer structure between the rear tripod 2 and the front tripod 1 from being damaged while maintaining riding stability.

[0042] Reference Figure 2 and Figure 3 During downhill high-speed riding, it is usually necessary to maintain the wheelbase between the front and rear wheels, so an up and down sliding shock absorber is generally selected. Therefore, it is necessary to completely lock the articulated rotating shock absorber, and the following settings are correspondingly arranged: a swing clamp 52 is slidably penetrated by a locking rod 6, and the locking rod 6 penetrates the center of the locking block 51. The locking rod 6 is adsorbed by the unlocking electromagnet 54, and a through-rod spring 61 is arranged between the locking rod 6 and the swing clamp 52. The ability of the through-rod spring 61 to resist deformation is less than that of the closing spring 53. Therefore, the middle connecting rod 3 can be completely locked with the help of the cooperation between the locking rod 6 and the locking block 51. In addition, the unlocking electromagnet 54 is started, but the strength of the magnetic field can only make the locking rod 6 disengage from the locking block 51. However, when the swing clamp 52 still clamps the locking block 51, a minimum amplitude of articulated rotating shock absorber can still be formed.

[0043] The implementation principle of a bicycle frame with a connecting rod shock absorption system in an embodiment of the present application is as follows: when encountering a small bump, the swing control component 5 releases the lock between the middle connecting rod 3 and the vertical shock absorption slide 11, so that the rear triangle 2 and the front triangle 1 rotate relative to each other, so that a hinged rotation method can be used for shock absorption; when encountering a large bump, the vertical control component 4 releases the lock of the vertical shock absorption slide 11, so that the rear triangle 2 and the front triangle 1 slide relative to each other vertically, so that an up and down sliding method can be used for shock absorption. Therefore, during the shock absorption process, the axis of the rear wheel will not produce a large horizontal displacement, so that the rider's center of gravity is more stable, thereby making riding safer during the shock absorption process.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
