Description

Technical Field

[0001] This application relates to the field of electric vehicles, and more specifically, to a mechanical inverted front fork and an electric vehicle. Background Technology

[0002] The front fork is a component in electric vehicles used to connect the front wheel axle to the frame, providing support; the front fork contains a shock-absorbing mechanism to achieve shock absorption. In existing technology, the shock-absorbing mechanism is hydraulic, which typically has the following drawbacks: Hydraulic shock absorbers involve multiple tightly fitted components, such as pistons, oil seals, and hydraulic lines, resulting in complex structures, high manufacturing costs, cumbersome assembly, and low production efficiency. Hydraulic shock absorbers are prone to wear after long-term use, posing a risk of oil leakage and increasing maintenance costs. The viscosity of hydraulic oil is affected by temperature, and the performance of hydraulic shock absorbers fluctuates significantly under extreme weather conditions. Furthermore, the conventionally positioned front fork in existing technology results in poor handling. Utility Model Content

[0003] The purpose of this application is to provide a mechanical inverted front fork and an electric vehicle to alleviate the technical problems of poor fork handling, high manufacturing cost, low production efficiency, high maintenance cost and unstable performance in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: In a first aspect, the mechanical inverted front fork provided by this utility model includes a sleeve assembly, a stem tube assembly, and a shock absorption assembly; The sleeve assembly includes a column, a connecting plate, and two sleeve bodies. The column is fixedly connected to the middle of the connecting plate, and the first ends of the two sleeve bodies are respectively fixedly connected to the two ends of the connecting plate. The handle assembly includes a handle body and a limiting seat. The limiting seat is installed on the outer wall of the handle body. One end of the handle body extends into the sleeve body from the second end of the sleeve body and slides with the sleeve body. The other end of the handle body is used to connect to the front wheel. The limiting seat is located in the sleeve body. The shock-absorbing assembly includes a shock-absorbing elastic element and a buffer elastic element, both located within the sleeve body. The shock-absorbing elastic element is located between the sleeve body and the handle tube body. The buffer elastic element is sleeved on the handle tube body, with one end connected to the limiting seat and the other end connected to the sleeve body.

[0005] Furthermore, the shock-absorbing assembly includes a buffer element installed inside the shock-absorbing elastic element.

[0006] Furthermore, the handle assembly includes a first guide sleeve and a second guide sleeve; The first guide sleeve is installed at the end of the handle body that extends into the sleeve body; The second guide sleeve is fitted onto the handle body, and the limiting seat is located between the first guide sleeve and the second guide sleeve; The second guide sleeve is connected to the sleeve body; The two ends of the buffer elastic element are respectively connected to the limiting seat and the second guide sleeve.

[0007] Furthermore, the handle assembly also includes a locking member, which is sleeved on the outer periphery of the handle body and located at the end of the second guide sleeve away from the buffer elastic member; The locking element engages with the sleeve body.

[0008] Furthermore, the handle assembly also includes a dustproof component, which is sleeved on the handle body and located at the end of the locking component away from the second guide sleeve; The dustproof component is sealed to the sleeve body.

[0009] Furthermore, the handle assembly also includes a connector and a reflector, the connector being mounted on one end of the handle body that extends out of the sleeve body, and the reflector being mounted on the outer wall of the connector.

[0010] Furthermore, the sleeve body includes a cylindrical portion and a fastening plug, one end of the cylindrical portion extends into the through hole of the connecting plate and is welded to the connecting plate, and the other end is slidably connected to the handle body; The fastening plug is connected to the cylindrical portion and abuts against the shock-absorbing elastic element.

[0011] Furthermore, the sleeve assembly includes a decorative element mounted on the connecting plate and covering the fastening plug.

[0012] Furthermore, the sleeve assembly includes a steering limit plate, which is mounted on the connecting plate and surrounds the outer periphery of the column, and the steering limit plate restricts the rotation angle range of the column.

[0013] Secondly, the electric vehicle provided by this utility model includes a front wheel and a mechanical inverted front fork as described in any of the above claims; The stem body of the mechanical inverted fork is connected to the axle of the front wheel.

[0014] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows: The mechanical inverted front fork provided by this utility model includes a sleeve assembly, a stem assembly, and a shock absorption assembly. The sleeve assembly includes a column, a connecting plate, and two sleeve bodies. The column is fixedly connected to the middle of the connecting plate, and the first ends of the two sleeve bodies are respectively fixedly connected to the two ends of the connecting plate. The stem assembly includes a stem body and a limiting seat. The limiting seat is installed on the outer wall of the stem body. One end of the stem body extends into the sleeve body from the second end of the sleeve body and slides with the sleeve body. The other end of the stem body is used to connect to the front wheel. The limiting seat is located inside the sleeve body. The shock absorption assembly includes a shock-absorbing elastic element and a buffer elastic element, both located inside the sleeve body. The shock-absorbing elastic element is located between the sleeve body and the stem body. The buffer elastic element is sleeved on the stem body, with one end connected to the limiting seat and the other end connected to the sleeve body.

[0015] The sleeve assembly includes a fixedly connected column, connecting plate, and two sleeve bodies, forming an integrated structure. This reduces the assembly steps of the fork and improves the structural strength of the sleeve assembly.

[0016] The stem assembly includes a stem body and a limiting seat. One end of the stem body slides into the sleeve body, and the other end is connected to the front wheel, making the front fork in an inverted structure. A shock-absorbing elastic element is installed between the top of the stem body and the top wall of the sleeve body, and a buffer elastic element is installed between the limiting seat and the sleeve body. The limiting seat is used to install the buffer elastic element. The shock-absorbing elastic element and the buffer elastic element in the shock-absorbing assembly work together to improve the vibration filtering efficiency.

[0017] The aforementioned inverted structure refers to inverting the inner and outer tubes of a traditional fork. In a traditional fork, the inner tube is positioned above the outer tube, with its bottom end sliding into and engaging with the outer tube, which is then connected to the front wheel. The inverted structure places the sleeve body above the stem body, with the stem body's outer diameter being smaller than the sleeve body's outer diameter, and the stem body's mass being smaller than the sleeve body's mass. This allows for a lighter stem body to connect to the front wheel, reducing the mass below the shock-absorbing elastic element. Because heavier objects have greater inertia and are less responsive to external forces, the inverted structure places the lighter stem body below, resulting in more sensitive road feedback and improved response to small impacts. Furthermore, the inverted structure uses the larger outer diameter sleeve body as the stress point, improving the lateral force distribution of the entire fork and enhancing its torsional resistance.

[0018] This mechanical inverted front fork employs a combination of shock-absorbing and cushioning elastic components for synergistic damping, achieving mechanical shock absorption. Its simple structure reduces the number of parts in the shock absorption assembly; it eliminates the need for hydraulic oil, fundamentally preventing oil leaks; it extends maintenance intervals and reduces operating costs; and its damping effect is unaffected by temperature changes, improving environmental adaptability. This mechanical inverted front fork reduces unsprung mass, improves suspension response, increases bending and torsional stiffness, and enhances handling. Attached Figure Description

[0025] Example 1 See Figure 1 and Figure 2 The mechanical inverted front fork provided in this embodiment includes a sleeve assembly 100, a stem tube assembly 200, and a shock absorption assembly 300. The sleeve assembly 100 includes a column 110, a connecting plate 120, and two sleeve bodies 130. The column 110 is fixedly connected to the middle of the connecting plate 120, and the first ends of the two sleeve bodies 130 are respectively fixedly connected to the two ends of the connecting plate 120. The stem tube assembly 200 includes a stem tube body 210 and a limiting seat 220. The limiting seat 220 is installed on the outer wall of the stem tube body 210. One end of the stem tube body 210 extends from the sleeve body... The second end of the body 130 extends into the sleeve body 130 and slides in cooperation with the sleeve body 130. The other end of the handle tube body 210 is used to connect to the front wheel. The limiting seat 220 is located inside the sleeve body 130. The shock absorption assembly 300 includes a shock absorption elastic member 310 and a buffer elastic member 320, both located inside the sleeve body 130. The shock absorption elastic member 310 is located between the sleeve body 130 and the handle tube body 210. The buffer elastic member 320 is sleeved on the handle tube body 210, with one end connected to the limiting seat 220 and the other end connected to the sleeve body 130.

[0026] Specifically, the sleeve body 130 is connected to the frame of the electric vehicle, so that the stress point of the mechanical inverted front fork is located on the sleeve body 130. Furthermore, in this embodiment, the column 110, the connecting plate 120, and the two sleeve bodies 130 are welded together, making the sleeve assembly 100 a one-piece structure that requires no further assembly. The limiting seat 220 is riveted to the outer wall of the handle tube body 210, enhancing the mechanical limiting stability of the limiting seat 220.

[0027] The sleeve assembly 100 includes a fixedly connected column 110, a connecting plate 120, and two sleeve bodies 130, forming an integrated structure. This reduces the assembly steps of the fork and improves the structural strength of the sleeve assembly 100. The stem tube assembly 200 includes a stem tube body 210 and a limiting seat 220. One end of the stem tube body 210 slides with the sleeve body 130, and the other end is connected to the front wheel, making the fork as a whole inverted structure. A shock-absorbing elastic element 310 is installed between the top of the stem tube body 210 and the top wall of the sleeve body 130, and a buffer elastic element 320 is installed between the limiting seat 220 and the sleeve body 130. The limiting seat 220 is used to install the buffer elastic element 320. The shock-absorbing elastic element 310 and the buffer elastic element 320 in the shock-absorbing assembly 300 work together to improve the vibration filtering efficiency.

[0028] The aforementioned inverted structure refers to inverting the inner and outer tubes of a traditional fork. In a traditional fork, the inner tube is positioned above the outer tube, with its bottom end extending into and slidingly engaging with it. The outer tube connects to the front wheel. In this inverted structure, the sleeve body 130 is positioned above the stem body 210. The outer diameter of the stem body 210 is smaller than that of the sleeve body 130, and the mass of the stem body 210 is less than that of the sleeve body 130. This allows the lighter stem body 210 to connect to the front wheel, reducing the mass below the shock-absorbing elastic element 310. Because objects with greater mass have greater inertia and are less responsive to external forces, the inverted structure places the lighter stem body 210 below, resulting in more sensitive road feedback and improved response to small impacts. Furthermore, the inverted structure uses the larger outer diameter sleeve body 130 as the stress point, improving the lateral force distribution of the entire fork and enhancing its torsional resistance.

[0029] This mechanical inverted front fork employs a shock-absorbing elastic element 310 and a buffer elastic element 320 for synergistic damping, achieving mechanical damping. Its simple structure reduces the number of parts in the shock-absorbing assembly 300; it eliminates the need for hydraulic oil, fundamentally preventing oil leaks; it extends maintenance cycles and reduces operating costs; and its damping effect is unaffected by temperature changes, improving environmental adaptability. This mechanical inverted front fork reduces unsprung mass, improves suspension response, increases bending and torsional stiffness, and enhances handling.

[0030] The following is a detailed description of the structure and shape of a mechanical inverted fork: In the optional solution provided by this utility model embodiment, the shock absorption component 300 includes a buffer 330, which is installed inside the shock absorption elastic component 310.

[0031] Specifically, both the shock-absorbing elastic element 310 and the buffer elastic element 320 are configured as springs, and the elastic coefficients of the shock-absorbing elastic element 310 and the buffer elastic element 320 are different. The buffer element 330 is made of rubber and is elastic. Preferably, see [link to relevant documentation]. Figure 3 and Figure 4 The end face of the buffer 330 near the stem body 210 is arc-shaped to reduce the contact area between the buffer 330 and the stem body 210 when the mechanical inverted fork is in an unloaded state. When the mechanical inverted fork is under load, the stem body 210 moves towards the sleeve body 130, and the contact area between the stem body 210 and the buffer 330 gradually increases until the contact area remains constant; this arc-shaped surface increases the deformability of the buffer 330. See also Figure 3 and Figure 7 The end face of the buffer 330 away from the handle tube body 210 is recessed downward to form a deformation cavity 331, which further increases the deformability of the buffer 330.

[0032] The buffer 330 is located inside the shock-absorbing elastic member 310 and is elastic, which can guide the shock-absorbing elastic member 310.

[0033] In the optional embodiment of this utility model, the handle assembly 200 includes a first guide sleeve 230 and a second guide sleeve 240; the first guide sleeve 230 is installed at the end of the handle body 210 that extends into the sleeve body 130; the second guide sleeve 240 is sleeved on the handle body 210, and the limiting seat 220 is located between the first guide sleeve 230 and the second guide sleeve 240; the second guide sleeve 240 is connected to the sleeve body 130; the two ends of the buffer elastic member 320 are respectively connected to the limiting seat 220 and the second guide sleeve 240.

[0034] Specifically, see Figure 4 and Figure 5 The first guide sleeve 230 engages with the handle body 210, and the outer diameter of the first guide sleeve 230 is larger than the outer diameter of the handle body 210. The outer wall of the first guide sleeve 230 fits against the inner wall of the sleeve body 130, thus guiding the handle body 210. Preferably, the inner wall of the handle body 210 is provided with a first limiting groove 211. The first guide sleeve 230 includes a fitting portion 231 and a engaging portion 232, with the engaging portion 232 located inside the fitting portion 231. The fitting portion 231 is fitted onto the outer periphery of the handle body 210, and the outer wall of the engaging portion 232 is provided with a first limiting protrusion 233, which is inserted into the first limiting groove 211. See also Figure 4 and Figure 6The inner wall of the second guide sleeve 240 fits against the outer wall of the handle body 210, and the two slide together; the second guide sleeve 240 is connected to the second end of the sleeve body 130; the buffer elastic element 320 is connected to the second guide sleeve 240, realizing the indirect connection between the buffer elastic element 320 and the sleeve body 130. The outer wall of the second guide sleeve 240 is provided with a second limiting protrusion 241, and the inner wall of the sleeve body 130 is provided with a second limiting groove 133, and the second limiting protrusion 241 is inserted into the second limiting groove 133.

[0035] The first guide sleeve 230 and the second guide sleeve 240 of the mechanical inverted front fork form a double guide sleeve structure, which ensures the accurate movement trajectory of the shock-absorbing elastic element 310 and the buffer elastic element 320, while reducing the difficulty of installation.

[0036] In the optional solution provided by this utility model embodiment, the handle tube assembly 200 further includes a locking member 250, which is sleeved on the outer periphery of the handle tube body 210 and located at the end of the second guide sleeve 240 away from the buffer elastic member 320; the locking member 250 is engaged with the sleeve body 130.

[0037] Specifically, see Figure 2 and Figure 3 The locking element 250 is a retaining circlip. See also Figure 4 and Figure 6 The bottom wall of the second limiting groove 133 of the sleeve body 130 is provided with a third limiting groove 134, and the snap ring is engaged in the third limiting groove 134.

[0038] The locking element 250 is used to fix the second guide sleeve 240.

[0039] In the optional solution provided by this utility model embodiment, the handle tube assembly 200 further includes a dustproof component 260, which is sleeved on the handle tube body 210 and located at the end of the locking component 250 away from the second guide sleeve 240; the dustproof component 260 is sealed to the sleeve body 130.

[0040] Specifically, see Figure 4 and Figure 6 The outer wall of the dustproof component 260 is provided with a sealing protrusion 261, which abuts against the end face of the sleeve body 130.

[0041] The dustproof component 260 is used to seal the second end of the sleeve body 130, reducing the intrusion of mud and sand, reducing the wear of internal components of the sleeve body 130, and extending the service life of the mechanical inverted fork.

[0042] In the optional solution provided by this utility model embodiment, the handle assembly 200 further includes a connector 270 and a reflector 280. The connector 270 is installed at one end of the handle body 210 that extends out of the sleeve body 130, and the reflector 280 is installed on the outer wall of the connector 270.

[0043] Specifically, see Figure 2 The connector 270 is threaded to the bottom end of the handle body 210, and the connector 270 is made of aluminum alloy to reduce its weight. The reflector 280 can be embedded in or bonded to the connector 270.

[0044] The connector 270 is made of aluminum alloy, which further reduces unsprung mass and improves shock absorption performance.

[0045] In the optional solution provided by this utility model embodiment, the sleeve body 130 includes a cylindrical part 131 and a fastening plug 132. One end of the cylindrical part 131 extends into the through hole of the connecting plate 120 and is welded to the connecting plate 120, and the other end is slidably connected to the handle tube body 210. The fastening plug 132 is connected to the cylindrical part 131 and abuts against the shock-absorbing elastic member 310.

[0046] Specifically, the fastening plug 132 is a screw plug, which is threadedly connected to the cylindrical portion 131. Further, see... Figure 4 and Figure 7 The top outer periphery of the fastening plug 132 is provided with a positioning protrusion 135, which fits against the upper surface of the connecting plate 120.

[0047] The cylinder portion 131 extends into the through hole of the connecting plate 120 and is welded to the connecting plate 120, increasing the contact area between the cylinder portion 131 and the connecting plate 120 and enhancing connection stability. The fastening plug 132 is installed at the top of the cylinder portion 131 to seal the top of the cylinder portion 131, reducing the intrusion of mud and sand, reducing wear on the internal components of the cylinder portion 131, and extending the service life of the mechanical inverted fork.

[0048] In the optional solution provided by this utility model embodiment, the sleeve assembly 100 includes a decorative part 140, which is installed on the connecting plate 120 and covered with a fastening plug 132.

[0049] Specifically, see Figure 4 and Figure 7 The decorative piece 140 is placed on top of the fastening plug 132 and is attached to the upper surface of the connecting plate 120.

[0050] Decorative component 140 enhances the aesthetic appeal of the mechanical inverted fork.

[0051] In the optional solution provided by this utility model embodiment, the sleeve assembly 100 includes a steering limit plate 150, which is installed on the connecting plate 120 and surrounds the outer periphery of the column 110. The steering limit plate 150 limits the rotation angle range of the column 110.

[0052] Specifically, the steering limit plate 150 is welded to the connecting plate 120. See also Figure 2The steering limit plate 150 is provided with a groove 151, which cooperates with the electric vehicle frame to limit movement.

[0053] The steering limit plate 150, column 110, connecting plate 120 and sleeve body 130 are welded into a single structure, reducing assembly steps and improving structural strength.

[0054] The following is a detailed explanation of the assembly method for mechanical inverted front forks: The first guide sleeve 230 is installed on the top of the handle body 210 and engaged with the first limiting groove 211; then the buffer elastic element 320 and the second guide sleeve 240 are sequentially fitted onto the handle body 210 to form the first shock absorption module. A layer of grease is applied to the inner wall of the sleeve body 130. The first shock-absorbing module is inserted into the sleeve body 130. The locking part 250 and the dustproof part 260 are installed in sequence. Then the connector 270 is tightened and the reflector 280 is installed on the connector 270. After immersing the shock-absorbing elastic element 310 in grease, it is installed into the sleeve body 130 together with the buffer element 330. The fastening plug 132 is tightened and the decorative element 140 is covered to complete the assembly.
