Description

Technical Field

[0001] This application relates to the field of children's vehicle technology, and in particular to a touring balance bike. Background Technology

[0002] Balance bikes, as an important product in the field of children's vehicle technology, have seen significant development in recent years. Initially, balance bikes were mainly used as a single training tool for children, helping them improve their balance and learn to propel themselves forward by pushing off the ground with their feet. They also helped children learn to control the handlebars to change direction, improving their sense of direction. Over time, the functions of balance bikes have gradually expanded, evolving from a simple training tool into a children's transportation tool, meeting the needs of children's frequent outdoor play in family outings.

[0003] During the use of balance bikes, in order to reduce their space occupation, it is often necessary to disassemble and assemble the front fork pulley assembly and / or rear fork pulley assembly. In the existing technology, the conventional solution is to use tools to operate, such as screwdrivers, wrenches, etc., to connect and disconnect the front fork pulley assembly and rear fork pulley assembly from the frame by tightening or loosening screws, nuts and other connecting parts. This results in low disassembly and assembly efficiency, so further improvement is needed. Utility Model Content

[0004] To enable tool-free quick assembly and disassembly of the front or rear fork pulley assembly, this application provides a travel balance bike.

[0005] The travel balance bike provided in this application adopts the following technical solution: A balance bike includes a frame, a head axle rotatably connected to the front end of the frame, a front fork pulley assembly detachably connected to the head axle, and a rear fork pulley assembly detachably connected to the rear end of the frame. Both the front and rear fork pulley assemblies include a fork seat detachably connected to the head axle / frame via a first anti-detachment component, a fork arm fixedly connected to the outer wall of the fork seat, and a wheel connected to the fork arm. The first anti-detachment component includes a rod disposed on the head axle / frame and a spring clip disposed on the rod. The spring clip normally protrudes from the outer wall of the rod. The fork seat has a insertion hole for inserting the rod, and the outer wall of the fork seat has a locking hole communicating with the insertion hole for the spring clip to be engaged.

[0006] By adopting the above technical solution, the insertion rod and spring buckle of the first anti-detachment component, together with the insertion hole and snap hole of the fork seat, realize the quick disassembly and assembly of the front fork pulley assembly or the rear fork pulley assembly. Disassembly and assembly can be completed without relying on tools, thereby improving the disassembly and assembly efficiency of the front fork pulley assembly or the rear fork pulley assembly.

[0007] Preferably, a second anti-detachment component is provided between the fork and the insertion rod.

[0008] By adopting the above technical solution, a second anti-detachment component is set between the fork seat and the insert bar of the balance bike, which further enhances the stability of the connection between the front fork pulley assembly and the rear fork pulley assembly and the head axle and frame.

[0009] Preferably, the second anti-detachment component includes a locking sleeve and a locking nut fixedly connected to one end of the fork seat. The insertion rod is inserted into the locking sleeve. The outer peripheral wall of the locking sleeve has an external thread. The end of the locking sleeve away from the fork seat has a deformation groove along the axial direction. There are multiple deformation grooves distributed around the axis of the locking sleeve. The inner peripheral wall of the locking nut has an internal thread that is threaded to the external thread. After the locking nut is locked onto the locking sleeve, the inner peripheral wall of the locking sleeve abuts against the outer wall of the insertion rod.

[0010] By adopting the above technical solution, the spring buckle of the first anti-detachment component cooperates with the snap-fit ​​hole of the fork seat to achieve initial anti-detachment; on this basis, the locking sleeve and locking nut of the second anti-detachment component cooperate, the external thread of the outer peripheral wall of the locking sleeve is threadedly connected with the internal thread of the inner peripheral wall of the locking nut, and multiple deformation grooves make the inner peripheral wall of the locking sleeve press against the outer wall of the insertion rod when the locking nut is locked, so that the locking sleeve holds the insertion rod tightly, further enhancing the stability of the connection between the front fork pulley assembly and the rear fork pulley assembly and the head axle / frame, and improving the overall stability of the balance bike.

[0011] Preferably, the outer wall of the fork seat is provided with a mounting groove communicating with the insertion hole, and the second anti-detachment component includes a hinge shaft rotatably connected to the inner wall of the mounting groove, an anti-detachment cam fixedly sleeved on the hinge shaft, and a quick-release handle fixedly connected to the outer wall of the anti-detachment cam. The axial direction of the hinge shaft is parallel to the axial direction of the insertion rod, and the outer wall of the insertion rod is provided with a limiting hole for the protrusion of the anti-detachment cam to be rotatably inserted.

[0012] By adopting the above technical solution, the spring buckle of the first anti-detachment component cooperates with the snap-fit ​​hole of the fork seat to achieve initial anti-detachment; on this basis, rotating the quick-release handle can make the anti-detachment cam rotate around the hinge axis, and embed the protrusion of the anti-detachment cam into the limiting hole on the outer wall of the plug rod, thereby achieving anti-detachment locking of the connection between the fork seat and the plug rod, realizing double insurance, and improving the stability of the connection between the front fork pulley assembly and the rear fork pulley assembly of the balance bike and the head axle and frame.

[0013] Preferably, when the protrusion of the anti-detachment cam rotates and is inserted into the limiting hole, the end of the quick-release handle away from the anti-detachment cam is located outside the snap-fit ​​hole to cover the spring clip.

[0014] By adopting the above technical solution, when the protrusion of the anti-detachment cam rotates and is inserted into the limiting hole, the end of the quick-release handle away from the anti-detachment cam covers the spring clip, so that the spring clip is hidden and can prevent the spring clip from being accidentally touched and pressed and dislodged from the locking hole.

[0015] Preferably, the anti-detachment cam is a plastic part, the limiting hole is a blind hole, and when the end of the quick-release handle away from the hinge shaft is attached to the outer wall of the fork seat, the outer peripheral wall of the protrusion of the anti-detachment cam abuts against the bottom inner wall of the limiting hole.

[0016] By adopting the above technical solution, the elastic deformation performance of the anti-detachment cam in the plastic part is utilized to ensure that the cam protrusion tightly abuts against the inner wall of the bottom of the blind hole when the quick-release handle is attached to the outer wall of the fork seat, thereby enhancing the connection stability and avoiding wear caused by rigid contact, thus extending the service life of the component.

[0017] Preferably, the insertion rod has an installation cavity at one end near the fork seat, the limiting hole is connected to the installation cavity, the insertion rod is provided with a resistance-increasing bushing fixed in the installation cavity, the resistance-increasing bushing is a plastic part, and the outer peripheral wall of the protrusion of the anti-detachment cam abuts against the outer wall of the resistance-increasing bushing.

[0018] By adopting the above technical solution, the resistance-increasing bushing is set in the insertion rod mounting cavity, and the outer peripheral wall of the protrusion of the anti-detachment cam abuts against the outer wall of the resistance-increasing bushing. The characteristics of the plastic parts are used to increase the friction between the anti-detachment cam and the insertion rod, so that the anti-detachment cam has a better limiting effect on the insertion rod.

[0019] Preferably, the front fork pulley assembly and the rear fork pulley assembly have the same structural dimensions.

[0020] By adopting the above technical solution, the front fork pulley assembly and the rear fork pulley assembly have the same structural dimensions, making them universal front and rear fork assemblies. Any universal front and rear fork assembly can be connected to the head axle / frame, improving installation efficiency.

[0021] Preferably, the outer wall of the insertion rod has a first anti-rotation groove, and the inner wall of the insertion hole protrudes to fit the first anti-rotation protrusion of the first anti-rotation groove.

[0022] By adopting the above technical solution, a first anti-rotation groove is provided on the outer wall of the insertion rod, and a first anti-rotation protrusion adapted to the first anti-rotation groove is provided on the inner wall of the insertion hole, which can prevent the insertion rod from rotating relative to the fork seat and improve the stability of the connection between the front fork pulley assembly and the rear fork pulley assembly and the head axle / frame.

[0023] Preferably, a stop sleeve is coaxially fixedly connected to the inner wall of the insertion hole, and there is a gap between the outer peripheral wall of the stop sleeve and the inner peripheral wall of the insertion hole. The outer peripheral wall of the stop sleeve is provided with a second anti-rotation groove. An installation cavity is provided at one end of the insertion rod near the fork seat. A second anti-rotation protrusion adapted to the second anti-rotation groove is fixedly protruding from the inner wall of the installation cavity. After the insertion rod is inserted into the insertion hole, the outer peripheral wall of the stop sleeve abuts against the inner wall of the installation cavity, and the outer peripheral wall of the insertion rod abuts against the inner wall of the insertion hole.

[0024] By adopting the above technical solution, when the insert rod is inserted into the insertion hole, the second anti-rotation protrusion in the mounting cavity matches the second anti-rotation groove on the outer peripheral wall of the stop sleeve, which can prevent the insert rod from rotating relative to the fork seat. Furthermore, the outer peripheral wall of the stop sleeve abuts against the inner wall of the mounting cavity, and the outer peripheral wall of the insert rod abuts against the inner wall of the insertion hole, further enhancing the stability of the connection between the insert rod and the fork seat.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0029] Example 1: This application discloses a travel balance bike, referring to... Figure 1 It includes a frame 1, a head axle 2 rotatably connected to the front end of the frame 1, a front fork pulley assembly 3 detachably connected to the head axle 2, and a rear fork pulley assembly 4 detachably connected to the rear end of the frame 1.

[0030] The frame 1 includes a main stem 11, a fork tube 12 fixedly connected to the front end of the main stem 11, and a seat tube 13 fixedly connected to the rear end of the main stem 11. A head axle 2 rotatably passes through the fork tube 12. A handlebar 21 is fixedly connected to the upper part of the head axle 2. The connection structure between the handlebar 21 and the head axle 2 is existing technology and will not be described in detail here. A seat post 14 is slidably inserted into the upper part of the seat tube 13. The seat post 14 is restricted from sliding by a seat post clamp 15. The seat post clamp 15 is existing technology and will not be described in detail here. A saddle 16 is fixedly connected to the upper part of the seat post 14. The seat post 14 can be slidably adjusted or removed by unlocking the seat post clamp 15.

[0031] Reference Figure 2 The front fork pulley assembly 3 and the rear fork pulley assembly 4 have the same structure and dimensions, making them universal front and rear fork assemblies. Either universal front or rear fork assembly can be connected to the head axle 2 / main shaft 11. The universal front and rear fork assembly includes a fork seat 41 detachably connected to the head axle 2 / main shaft 11 via a first anti-detachment component 5, fork arms 42 fixedly connected to the outer wall of the fork seat 41, and wheels 43 connected to the fork arms 42. Two fork arms 42 are provided and fixedly connected to the two outer walls of the fork seat 41 respectively. The wheels 43 are rotatably connected between the ends of the two fork arms 42 away from the fork seat 41 via a pivot. The fork seat 41 has an axially extending insertion hole 411, and the outer wall of the fork seat 41 has a snap-fit ​​hole 412 communicating with the insertion hole 411.

[0032] The first anti-detachment component 5 includes an insert rod 51 fixedly connected to the lower end of the head shaft 2 / the rear end of the main rod 11, and a spring clip 52 disposed on the insert rod 51. The insert rod 51 is slidably inserted into the insertion hole 411. Specifically, the outer wall of the insert rod 51 has a groove, and the spring clip 52 is slidably connected to the groove along the radial direction of the insert rod 51. The insert rod 51 is provided with an elastic element that forces the spring clip 52 to protrude from the outer wall under normal conditions. The elastic element can be a spring or a spring sheet. The side of the spring clip 52 near the fork seat 41 has a guide slope for the end face of the fork seat 41 to abut against, so as to force the spring clip 52 to slide towards the axis of the insert rod 51. When the spring clip 52 is aligned with the locking hole 412, the elastic element forces the spring clip 52 to slide and embed in the locking hole 412. In this embodiment, the outer wall of the insertion rod 51 has a first anti-rotation groove 511, and the inner wall of the insertion hole 411 protrudes to match the first anti-rotation protrusion 413 of the first anti-rotation groove 511. The first anti-rotation groove 511 and the first anti-rotation protrusion 413 cooperate to prevent the insertion rod 51 from rotating relative to the fork seat 41.

[0033] A second anti-detachment component 6 is provided between the fork seat 41 and the insert rod 51. The second anti-detachment component 6 increases the friction between the fork seat 41 and the insert rod 51 by means of threaded locking or cam pressing. In this embodiment, the second anti-detachment component 6 includes a locking sleeve 61 and a locking nut 62 fixedly connected to one end of the fork seat 41. Both the locking sleeve 61 and the locking nut 62 are plastic parts. The outer peripheral wall of the locking sleeve 61 has external threads. The end of the locking sleeve 61 away from the fork seat 41 has a deformation groove 611 along the axial direction. There are multiple deformation grooves 611 and they are distributed around the axis of the locking sleeve 61. The fork seat 41 is a metal part or a plastic part, and the insert rod 51 is a metal part or a plastic part. In this embodiment, the locking sleeve 61 is coaxially fixedly connected to the end of the fork seat 41 away from the wheel 43. The fork seat 41 and the fork arm 42 are both plastic parts, and the fork seat 41, the fork arm 42 and the locking sleeve 61 are integrally formed. The insert rod 51 is inserted into the locking sleeve 61. The inner circumferential wall of the locking nut 62 has an internal thread that is threaded to the external thread. After the locking nut 62 is locked into the locking sleeve 61, the inner circumferential wall of the locking sleeve 61 abuts against the outer wall of the insert rod 51, thereby reducing the shaking between the fork seat 41 and the insert rod 51.

[0034] The implementation principle of this application embodiment is as follows: for the installation of the front fork pulley assembly 3 or the rear fork pulley assembly 4: first, the locking nut 62 is sleeved on the insert rod 51, then the insert rod 51 is slidably inserted into the insertion hole 411, after the spring buckle 52 and the snap-fit ​​hole 412 are aligned, the spring buckle 52 is snapped into the snap-fit ​​hole 412, and finally the locking nut 62 is rotated so that the locking sleeve 61 holds the insert rod 51 tightly, which enhances the stability of the connection between the front fork pulley assembly 3 and the rear fork pulley assembly 4 and the head axle 2 / frame 1, and improves the overall stability of the balance bike. Disassembly of the front fork pulley assembly 3 or the rear fork pulley assembly 4: First, unscrew the locking nut 62, then press the spring clip 52 through the snap-fit ​​hole 412, causing the spring clip 52 to retract into the recess, releasing the sliding restriction of the insertion rod 51, and then pulling out the insertion rod 51. This achieves quick disassembly and assembly of the front fork pulley assembly 3 or the rear fork pulley assembly 4 without the need for tools, thus improving the efficiency of disassembly and assembly of the front fork pulley assembly 3 or the rear fork pulley assembly 4.

[0035] Example 2: The difference from Example 1 is that, referring to Figure 3 In this embodiment, the locking sleeve 61 is coaxially fixedly connected to one end of the fork seat 41 near the wheel 43.

[0036] Example 3: The difference from Example 1 is that, referring to Figure 4 , Figure 5 The end of the fork seat 41 away from the insertion rod 51 is a closed end. The top outer wall of the fork seat 41 has a mounting groove 414 communicating with the insertion hole 411, and a snap-fit ​​hole 412 is opened on the side wall of the fork seat 41. In this embodiment, the second anti-detachment component 6 includes a hinge shaft 63 rotatably connected to the inner wall of the mounting groove 414, an anti-detachment cam 64 fixedly sleeved on the hinge shaft 63, and a quick-release handle 65 fixedly connected to the outer wall of the anti-detachment cam 64. The axial direction of the hinge shaft 63 is parallel to the axial direction of the insertion rod 51, and the outer wall of the insertion rod 51 has a limiting hole 513 for the protrusion of the anti-detachment cam 64 to be rotatably inserted.

[0037] Reference Figure 5 , Figure 6 , Figure 7 In this embodiment, the anti-detachment cam 64 is a metal part, the insertion rod 51 is a metal part, and the insertion rod 51 has an installation cavity 512 at one end near the fork seat 41. In this embodiment, the limiting hole 513 is connected to the installation cavity 512. The insertion rod 51 is provided with a resistance-increasing bushing 53 fixed to the installation cavity 512. The resistance-increasing bushing 53 is a plastic part, and the spring buckle 52 is provided on the resistance-increasing bushing 53. When the protrusion of the anti-detachment cam 64 rotates and is inserted into the limiting hole 513, the outer peripheral wall of the protrusion of the anti-detachment cam 64 abuts against the outer wall of the resistance-increasing bushing 53, and the end of the quick-release handle 65 away from the anti-detachment cam 64 is located outside the snap-fit ​​hole 412 to cover the spring buckle 52.

[0038] A stop sleeve 415 is coaxially fixedly connected to the inner wall of the insertion hole away from the insertion rod 51 of the fork seat 41. There is a gap between the outer peripheral wall of the stop sleeve 415 and the inner peripheral wall of the insertion hole 411. A second anti-rotation groove 416 is provided on the outer peripheral wall of the stop sleeve 415. A second anti-rotation protrusion 531 adapted to the second anti-rotation groove 416 is fixedly protruding from the inner wall of the resistance-increasing bushing 53. After the insertion rod 51 is inserted into the insertion hole 411, the outer peripheral wall of the stop sleeve 415 abuts against the inner wall of the resistance-increasing bushing 53, and the outer peripheral wall of the insertion rod 51 abuts against the inner wall of the insertion hole 411.

[0039] The implementation principle of this application embodiment is as follows: Installation of the front fork pulley assembly 3 or the rear fork pulley assembly 4: In the initial state, the protrusion of the anti-detachment cam 64 rotates to the top of the limiting hole 513. First, the insertion rod 51 is slidably inserted into the insertion hole 411. After the spring buckle 52 and the locking hole 412 are aligned, the spring buckle 52 is locked into the locking hole 412. Finally, the quick release handle 65 is pulled down to drive the anti-detachment cam 64 to rotate, so that the outer peripheral wall of the protrusion of the anti-detachment cam 64 abuts against the outer wall of the resistance-increasing bushing 53. At this time, the resistance-increasing bushing 53 will deform under the action of the protrusion of the anti-detachment cam 64, increasing the friction between the anti-detachment cam 64 and the insertion rod 51, realizing the anti-detachment locking of the connection between the fork seat 41 and the insertion rod 51, realizing double insurance, reducing the shaking between the fork seat 41 and the insertion rod 51. The disassembly of the front fork pulley assembly 3 or the rear fork pulley assembly 4 can be performed by reversing the operation.

[0040] Example 4: The difference from Example 3 is that, referring to Figure 8 In this embodiment, the anti-detachment cam 64 is a plastic part, and the limiting hole 513 is a blind hole. When the end of the quick-release handle 65 away from the hinge shaft 63 is attached to the outer wall of the fork seat 41, the outer peripheral wall of the protrusion of the anti-detachment cam 64 abuts against the bottom inner wall of the limiting hole 513, causing the protrusion of the anti-detachment cam 64 to deform and increasing the friction between the anti-detachment cam 64 and the insertion rod 51. In other embodiments, both the anti-detachment cam 64 and the insertion rod 51 are plastic parts.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
