Description

Technical Field

[0001] This utility model relates to the field of bicycle front fork technology, and in particular to a locking mechanism for bicycle front forks. Background Technology

[0002] In the field of bicycle fork technology, the locking function of the fork is crucial for improving the riding experience. It can switch the shock absorption state of the fork according to road conditions (such as locking to reduce energy loss, or unlocking to enhance the shock absorption effect).

[0003] In the existing technology, the locking mechanism of bicycle front fork still has certain shortcomings. Some traditional locking mechanisms adopt a purely manual adjustment method, and the adjustment parts are mostly located at the lower part of the front fork or near the fork shoulder. Users need to bend over or reach to the front fork to operate, which is extremely inconvenient during riding and can easily cause the center of gravity to shift. This not only affects the continuity of riding, but also poses a significant safety hazard. Therefore, this application proposes a locking mechanism for bicycle front fork. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a locking mechanism for a bicycle front fork to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a locking mechanism for a bicycle front fork, comprising:

[0006] The outer tube is provided in two sets. A fork bridge is fixed between the top ends of the two outer tubes, and a fork foot is fixed between the bottom ends of the two outer tubes.

[0007] The stroke tube is provided in two sets and is inserted into the top of the two outer tubes respectively;

[0008] The fork shoulder is in the shape of an inverted V and is located above the two stroke tubes. Both ends of the bottom of the fork shoulder are fixedly installed with shoulder caps that are fitted onto the top of the two stroke tubes, and the top of the fork shoulder is fixedly installed with a vertical main tube.

[0009] The handlebars are mounted on top of the supervisor's head;

[0010] A limiting tube is fixedly installed on the top of one of the shoulder caps;

[0011] Adjust the knob, rotate it to insert between the limit tubes and extend into the corresponding stroke tube;

[0012] The drive assembly is mounted on top of the limit tube and docks with the adjustment knob;

[0013] The control component is detachably mounted on the handlebars, and the control component and the drive component are electrically connected via a power cable.

[0014] Optionally, a semi-circular limiting groove is provided on the side of the limiting tube, and a toggle rod connected to the adjusting knob is inserted into the limiting groove. The top of the adjusting knob is provided with docking slots in a circular array. Both ends of the top of the limiting tube are provided with first insertion holes, and two second insertion holes corresponding to the first insertion holes are provided on both sides of the limiting tube.

[0015] Optionally, the drive assembly includes a docking rod, a motor, and a docking plate. The bottom end of the docking rod is installed on the top of the limiting tube. An inner groove is formed inside the docking rod, and a recess is formed at the bottom of the docking rod. An adjustment knob is located in the recess at the bottom of the docking rod. The motor is fixedly installed in the inner groove, and the output end of the motor extends into the recess. The docking plate is fixedly installed on the output end of the motor, and a docking block adapted to the docking slot is provided at the bottom of the docking plate. When the docking rod is located at the top of the limiting tube, the docking block at the bottom of the docking plate engages with the docking slot at the top of the adjustment knob.

[0016] Optionally, both ends of the bottom of the connecting rod are equipped with plugs that are compatible with the first insertion hole. The two plugs are respectively inserted into the corresponding first insertion hole, and through holes are opened on the side of the two plugs. A U-shaped plug is inserted between the two second insertion holes on the side of the limiting tube, and the two ends of the U-shaped plug pass through the insertion hole on the corresponding plug. Locking plates that fit against the outer wall of the limiting tube are sleeved on the two ends of the U-shaped plug that pass through the second insertion hole, and nuts that tightly abut against the locking plates are threaded on both ends of the U-shaped plug.

[0017] Optionally, the control assembly includes a battery module, a first clamp, and a control lever. The first clamp consists of two rings, the ends of which are hinged to the top and bottom of one side of the battery module, respectively. The two rings are closed and clamped to the handlebar by bolts. The side of the battery module connected to the first clamp fits tightly against the handlebar.

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0040] Please see Figures 1-6 This utility model provides a technical solution: a locking mechanism for a bicycle front fork, including an outer tube 11, two sets of outer tubes 11, a fork bridge fixedly connected between the top ends of the two outer tubes 11, and fork legs fixedly connected between the bottom ends of the two outer tubes 11. A travel tube 12 is inserted into the top end of each of the two outer tubes 11. An inverted V-shaped fork shoulder 13 is provided above the two travel tubes 12. Shoulder caps 14, fitted onto the top ends of the two travel tubes 12, are fixedly installed at both ends of the bottom of the fork shoulder 13. A vertical main tube 15 is fixedly installed at the top of the fork shoulder 13, and a handlebar 16 is fitted onto the top of the main tube 15. A limit tube 14 is fixedly installed on the top of one of the shoulder caps 14. 1. An adjustment knob 17 is inserted through the limit tubes 141, and the bottom end of the adjustment knob 17 extends into the corresponding stroke tube 12. A drive component 2 that docks with the adjustment knob 17 is installed on the top of the limit tubes 141. A detachable control component 3 is installed on the handlebars 16. The control component 3 and the drive component 2 are electrically connected through a power cable 4. By detachably installing the control component 3 on the handlebars 16 and electrically connecting it to the drive component 2 at the top of the limit tubes 141, the convenience of operation without bending over during riding is achieved, and a basic structural support is provided for the stable connection of each component and later maintenance, taking into account both operational convenience and structural rationality.

[0041] like Figure 2 and Figure 3As shown, a semi-circular limiting slot 142 is provided on the side of the limiting tube 141. A toggle rod 171 connected to the adjusting knob 17 is inserted into the limiting slot 142. The top of the adjusting knob 17 has a circular array of docking slots. Both ends of the top of the limiting tube 141 have first insertion holes 143. Two second insertion holes 144 are provided on both sides of the limiting tube 141, corresponding to the first insertion holes 143. The semi-circular limiting slot 142 of the limiting tube 141 restricts the rotation range of the toggle rod 171. When the drive assembly 2 is not powered, the adjusting knob 17 can be adjusted by the toggle rod 171, ensuring that the adjustment knob 17 moves accurately and controllably. The docking slot of the adjusting knob 17 and the first insertion holes 143 and second insertion holes 144 of the limiting tube 141 provide a matching structure for the accurate docking and stable installation of the drive assembly 2, improving the reliability of the adjustment mechanism and the stability of the connection in detail.

[0042] like Figure 3 and Figure 4 As shown, the drive assembly 2 includes a docking rod 21, a motor 22, and a docking plate 23. The bottom end of the docking rod 21 is mounted on the top of the limiting tube 141. An inner groove 211 is formed inside the docking rod 21, and a recess 212 is formed at the bottom of the docking rod 21. The adjusting knob 17 is located in the recess 212 at the bottom of the docking rod 21. The motor 22 is fixedly mounted in the inner groove 211, and the output end of the motor 22 extends into the recess 212. The docking plate 23 is fixedly mounted in the output end of the motor 22, and the bottom of the docking plate 23 is also fixedly mounted in the recess 212. With a docking block adapted to the docking slot, and the docking rod 21 located at the top of the limiting tube 141, the docking block at the bottom of the docking plate 23 engages with the docking slot at the top of the adjusting knob 17. The drive assembly 2 achieves efficient transmission of power from the motor 22 to the adjusting knob 17 through the precise engagement of the docking block of the docking plate 23 with the docking slot of the adjusting knob 17. The motor 22 is built into the inner groove 211 of the docking rod 21, which can prevent the motor 22 from being affected by external interference, ensure stable power transmission, and avoid drive failure.

[0043] like Figure 1 , Figure 2 and Figure 4As shown, both ends of the bottom of the connecting rod 21 are equipped with insert blocks 24 that are adapted to the first insertion hole 143. The two insert blocks 24 are respectively inserted into the corresponding first insertion hole 143, and through holes are opened on the side of the two insert blocks 24. A U-shaped insert rod 25 is inserted between the two second insertion holes 144 on the side of the limiting tube 141, and the two ends of the U-shaped insert rod 25 pass through the insertion holes on the corresponding insert blocks 24. The two ends of the U-shaped insert rod 25 passing through the second insertion holes 144 are fitted to fit the outer wall of the limiting tube 141. The locking plate 26 is provided, and nuts 27 are threaded on both ends of the U-shaped plug rod 25 to abut against the locking plate 26. The plug block 24 at the bottom of the connecting rod 21 is inserted into the first plug hole 143 at the top of the limiting tube 141. The U-shaped plug rod 25 passes through the second plug hole 144 and is fixed by the plug block 24, the locking plate 26 and the nuts 27, forming a multi-mechanical locking structure. This greatly enhances the connection strength between the drive assembly 2 and the limiting tube 141, effectively resists riding vibration, prevents loosening, and ensures long-term stable operation.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, the control assembly 3 includes a battery module 31, a first clamp 32, and a control lever 311. The first clamp 32 consists of two clamping rings, the ends of which are hinged to the top and bottom of one side of the battery module 31, respectively. The two clamping rings are closed and clamped to the handlebar 16 by bolts. The side of the battery module 31 connected to the first clamp 32 is tightly fitted to the handlebar 16. The control lever 311 is installed on the top of the battery module 31. The control assembly 3 is installed in the middle of the horizontal part of the handlebar 16. The first clamp 32 of the control assembly 3 adopts a double clamping ring bolt structure, which is compatible with different sizes of handlebar 16 and facilitates quick disassembly and maintenance. The design of installing it in the middle of the horizontal part of the handlebar 16 allows the user to easily operate the control lever 311 while riding, improving the convenience and safety of operation.

[0045] like Figure 1 , Figure 2 and Figure 6As shown, a second clamp 51 is fitted on the main pipe 15 and below the handlebar 16, and a third clamp 52 is fitted on the vertical part of the handlebar 16. The second clamp 51 and the third clamp 52 have the same structure, and the third clamp 52 is larger than the second clamp 51. Fixing blocks 511 are installed on the sides of the second clamp 51 and the third clamp 52. Openings are opened on both fixing blocks 511. The power cord 4 is inserted between the openings on the two fixing blocks 511, and the outer wall of the power cord 4 is tightly connected to the inner wall of the opening. The power cord 4 is a reserved part between the second clamp 51 and the third clamp 52. The second clamp 51 and the third clamp 52 constrain the power cord 4 through the openings of the fixing blocks 511. The tight connection can prevent the power cord 4 from shaking and wearing. The reserved part of the power cord 4 can adapt to the displacement caused by the rotation of the handlebar 16 or the deformation of the parts, preventing the power cord 4 from being pulled and damaged. This not only standardizes the arrangement of the power cord 4, but also extends the service life of the power cord 4.

[0046] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
