Description

Technical Field

[0001] This utility model relates to the field of children's stroller technology, and in particular to a dual-directional wheel system and a children's stroller. Background Technology

[0002] In most common strollers, the front wheels are swivel wheels, meaning they can rotate 360 ​​degrees for easy steering. However, when pushing a stroller on uneven surfaces, if the front wheels are not oriented and can still rotate 360 ​​degrees, they will wobble from side to side, making pushing very difficult.

[0003] Therefore, some strollers have a directional structure at the front wheels. When the stroller is pushed on uneven surfaces, the directional structure holds the front wheels in place, preventing them from swaying from side to side and thus saving effort. However, existing directional wheels have relatively complex structures, and each of the two front wheels has its own directional structure, meaning they cannot be oriented simultaneously, making operation cumbersome. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a simple wheel system with dual-directional control and a children's stroller.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a dual-directional wheel system, comprising:

[0006] The mounting body is equipped with a pedal;

[0007] The first wheel and the second wheel are movably mounted on the mounting body. Both the first wheel and the second wheel have a vertical rotation center, and both the first wheel and the second wheel can rotate freely along their own vertical rotation center.

[0008] The first directional locking pin and the second directional locking pin are both movably mounted on the mounting body;

[0009] A transmission mechanism is movably disposed on the mounting body and located between the first directional locking pin and the second directional locking pin. The pedal can drive the first directional locking pin and the second directional locking pin through the transmission mechanism.

[0010] Stepping on the pedal causes the first directional locking pin and the second directional locking pin to lock into the first wheel and the second wheel respectively, restricting the first wheel and the second wheel from rotating relative to their own vertical rotation center.

[0011] Furthermore, the first positioning locking pin and the second positioning locking pin are respectively provided with a first tension spring and a second tension spring;

[0012] When the first directional locking pin and the second directional locking pin are not locked into the first wheel and the second wheel, the first tension spring and the second tension spring are in a compressed state; the elastic force of the first tension spring and the second tension spring can respectively drive the first directional locking pin and the second directional locking pin to lock into the first wheel and the second wheel.

[0013] Furthermore, the transmission mechanism includes a directional slider and a directional auxiliary slider, both of which are slidably mounted on the mounting body, and the directional slider and the directional auxiliary slider are connected by a double directional pull wire;

[0014] The directional slider is connected to the first directional locking pin via a first pull line, and the directional auxiliary slider is connected to the second directional locking pin via a second pull line. The directional slider and the directional auxiliary slider can respectively tighten the first directional locking pin and the second directional locking pin via the first pull line and the second pull line, restricting the first directional locking pin and the second directional locking pin from locking into the first wheel and the second wheel, and at this time, both the first tension spring and the second tension spring are compressed.

[0015] When the directional slider and the directional auxiliary slider release the first pull cable and the second pull cable respectively, the elastic force of the first tension spring and the second tension spring respectively drives the first directional locking pin and the second directional locking pin to lock toward the first wheel and the second wheel.

[0016] Furthermore, the transmission mechanism also includes a pause slider, a pause turntable, and a fixed base. The fixed base is fixedly mounted on the mounting body, the pause slider is retractably mounted on the fixed base, and the pause turntable is movably mounted on the fixed base and moves against the pause slider and the directional slider respectively.

[0017] When the pedal is pressed, causing the first and second directional locking pins to lock into the first and second wheels, the pause turntable can be restricted to the fixed seat, preventing the directional slider from resetting, so that the first and second directional locking pins remain in the locked state.

[0018] Furthermore, the fixed base has an abutting inclined surface, and when the pause turntable abuts against the abutting inclined surface, the first directional locking pin and the second directional locking pin remain in the locked state.

[0019] Furthermore, the fixed base is provided with a slot, and the pause turntable is provided with a locking block;

[0020] When the first directional locking pin and the second directional locking pin are locked into the first wheel and the second wheel respectively, the locking block disengages from the locking groove and abuts against the fixed seat;

[0021] When the first directional locking pin and the second directional locking pin are in the unlocked state, the locking block is engaged in the locking slot, and the directional slider can return to its initial position.

[0022] Furthermore, the pause slider is provided with multiple first inclined surfaces, and the pause turntable is provided with second inclined surfaces;

[0023] The pause slider can push against the second inclined surface through the first inclined surface, causing the pause turntable to rotate.

[0024] Furthermore, a first return spring is provided between the directional slider and the mounting body, and a second return spring is provided between the directional auxiliary slider and the mounting body;

[0025] When the first directional locking pin and the second directional locking pin are locked into the first wheel and the second wheel respectively, both the first return spring and the second return spring are in a compressed state.

[0026] Furthermore, both the first wheel and the second wheel have an axle, both axles are arranged vertically upwards, and the two axles are configured as the vertical rotation center of the first wheel and the second wheel;

[0027] Both the first directional locking pin and the second directional locking pin are arranged parallel to the axle. The first wheel and the second wheel are respectively provided with a locking groove. The first directional locking pin and the second directional locking pin can be locked into the two locking grooves respectively, restricting the rotation of the first wheel and the second wheel relative to their own axle.

[0028] The technical solution adopted by this utility model to solve its technical problem is to also propose a children's stroller, including the above-mentioned dual-directional wheel system, wherein the first wheel and the second wheel are both configured as front wheels.

[0029] Compared with the prior art, the present invention has at least the following beneficial effects:

[0030] (1) In this utility model, stepping on the pedal causes the first directional locking pin and the second directional locking pin to lock onto the first wheel and the second wheel respectively. The first directional locking pin orients the first wheel, and the second directional locking pin orients the second wheel, that is, one step on the pedal results in double orientation, switching the wheel system to the orientation state. This wheel system can achieve the effect of one step on the pedal in double orientation, and the operation is simple.

[0031] (2) In this utility model, the directional slider and the directional auxiliary slider are connected by a double directional pull wire to achieve synchronous movement. Through the synchronous movement of the directional slider and the directional auxiliary slider, the first directional locking pin and the second directional locking pin are synchronously locked to the first wheel and the second wheel, and the overall structure is simple.

[0032] (3) In this utility model, the automatic ballpoint pen telescopic mechanism is formed by the cooperation of the pause slider, the fixed seat, and the pause turntable. This allows the wheel system to remain in the oriented state after switching to the oriented state, ensuring the stability of the structure. The cooperation of the three components can also keep the wheel system in the non-oriented state after it is reset to the non-oriented state. Attached Figure Description

[0052] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, 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, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0057] like Figures 1-6 As shown, this embodiment of a dual-directional wheel system mainly includes: a mounting body 1, a first wheel 2, a second wheel 3, a first directional locking pin 4, a second directional locking pin 5, and a transmission mechanism 6. The transmission mechanism 6 mainly includes: a directional slider 61, a directional auxiliary slider 62, a dual-directional pull cable 612, a pause slider 63, a pause turntable 64, and a fixing seat 65. The mounting body 1 is equipped with a pedal 10, which allows the user to orient or deorbit the wheel by stepping on it. The first wheel 2 and the second wheel 3 are each rotatably mounted on the mounting body 1. Specifically, both the first wheel 2 and the second wheel 3 have an axle 230, which are vertically upward, meaning they are perpendicular to the horizontal plane. The first wheel 2 and the second wheel 3 can rotate freely along their respective axles 230. Essentially, when not oriented, the first wheel 2 and the second wheel 3 are both omnidirectional wheels, meaning they are generally configured as the two front wheels of a stroller. The first directional locking pin 4 and the second directional locking pin 5 are both movably mounted on the mounting body 1, and can lock onto the first wheel 2 and the second wheel 3 respectively, thus orienting the first wheel 2 and the second wheel 3. The transmission mechanism 6 is movably mounted on the mounting body 1 and positioned between the first directional locking pin 4 and the second directional locking pin 5. Its main function is to transmit motion, transferring the action of the pedal 10 to the two directional locking pins. In this embodiment, the transmission mechanism 6 can be implemented in various ways. In this embodiment, it is implemented using a slidable directional slider 61 and a directional auxiliary slider 62 in conjunction with an automatic ballpoint pen telescopic mechanism (formed by a pause slider 63, a pause turntable, and a fixed base 65). Other implementation methods will not be described further here.

[0058] In practical use, the wheel system of this embodiment has an oriented state and an unoriented state. In the oriented state, the first oriented locking pin 4 and the second oriented locking pin 5 are locked into the first wheel 2 and the second wheel 3 respectively, restricting the rotation of the two wheels relative to their vertical rotation centers. In the unoriented state, the first oriented locking pin 4 and the second oriented locking pin 5 are not locked into the first wheel 2 and the second wheel 3 respectively, and the first wheel 2 and the second wheel 3 can rotate freely relative to their respective vertical rotation centers. When in the unoriented state, stepping on the pedal 10 can drive the transmission mechanism 6, causing the first oriented locking pin 4 and the second oriented locking pin 5 to lock onto the first wheel 2 and the second wheel 3 respectively, switching the wheel system to the oriented state. Specifically, the first oriented locking pin 4 and the second oriented locking pin 5 are both arranged parallel to the wheel axle 230, that is, both are arranged vertically and perpendicular to the horizontal plane. The first wheel 2 and the second wheel 3 are each provided with a locking groove 231. When the wheel system is in the oriented state, the first oriented locking pin 4 and the second oriented locking pin 5 are locked into the locking groove 231 on the first wheel 2 and the locking groove 231 on the second wheel 3 respectively.

[0059] In this implementation, by stepping on the pedal 10, the first directional locking pin 4 and the second directional locking pin 5 can be driven to lock onto the first wheel 2 and the second wheel 3 respectively. The first directional locking pin 4 oriented the first wheel 2, and the second directional locking pin 5 oriented the second wheel 3, i.e., one step achieves double orientation, switching the wheel system to the orientation state. This wheel system can achieve the effect of one step achieving double orientation, and the operation is simple. After the first wheel 2 and the second wheel 3 are double-oriented by one step, when the stroller is pushed on an uneven surface, the first wheel 2 and the second wheel 3 will not wobble, ensuring that pushing is effortless.

[0060] like Figures 5-7 As shown, in this embodiment, the first positioning locking pin and the second positioning locking pin are respectively provided with a first tension spring 40 and a second tension spring 50. When the wheel system is in an unoriented state, both the first tension spring 40 and the second tension spring 50 are in a compressed state. That is, when no other external force acts on the first positioning locking pin 4 and the second positioning locking pin 5: the elastic force of the first tension spring 40 can push the first positioning locking pin 4 to lock into the locking groove 231 on the first wheel 2, completing the orientation of the first wheel 2; the elastic force of the second tension spring 50 can push the second positioning locking pin 5 to lock into the locking groove 231 on the second wheel 3, completing the orientation of the second wheel 3. The first tension spring 40 and the second tension spring 50 are the direct power source for the orientation movement of the first positioning locking pin 4 and the second positioning locking pin 5.

[0061] The transmission mechanism 6 in this embodiment includes a directional slider 61 and a directional auxiliary slider 62. Both the directional slider 61 and the directional auxiliary slider 62 are slidably mounted on the mounting body 1, and are connected by a double directional pull wire 612. Specifically, one end of the double directional pull wire 612 is connected to the directional slider 61, and the other end is connected to the directional auxiliary slider 62. The double directional pull wire 612 ensures that the directional movements of the directional slider 61 and the directional auxiliary slider 62 are consistent, i.e., double directional. A double directional steel wire turntable is provided on the mounting body 1, and the double directional pull wire 612 bypasses the turntable to achieve the turning around of the double directional pull wire 612.

[0062] In practical use, the directional slider 61 and the directional auxiliary slider 62 are connected by a double directional pull wire 612 to achieve synchronous movement. Through the synchronous movement of the directional slider 61 and the directional auxiliary slider 62, the first directional locking pin 4 and the second directional locking pin 5 are synchronously locked to the first wheel 2 and the second wheel 3, resulting in a simple overall structure.

[0063] In this embodiment, the directional slider 61 is connected to the first directional locking pin 4 via a first pull wire 610, and the directional auxiliary slider 62 is connected to the second directional locking pin 5 via a second pull wire 620. When the wheel system is in an unoriented state, the directional slider 61 and the directional auxiliary slider 62 tighten the first directional locking pin 4 and the second directional locking pin 5 via the first pull wire 610 and the second pull wire 620, respectively, and both the first tension spring 40 and the second tension spring 50 are compressed. When the directional slider 61 and the directional auxiliary slider 62 release the first pull wire 610 and the second pull wire 620, respectively, the directional slider 61 moves towards the side closer to the first pull wire 610, and the directional auxiliary slider 62 moves towards the side closer to the second pull wire 620. The elastic force of the first tension spring 40 and the second tension spring 50 respectively drives the first directional locking pin 4 and the second directional locking pin 5 to lock towards the first wheel 2 and the second wheel 3, achieving dual orientation of the first wheel 2 and the second wheel 3.

[0064] To ensure that the directional slider 61 and the directional auxiliary slider 62 can be smoothly reset, a first reset spring 61A is provided between the directional slider 61 and the mounting body 1, and a second reset spring 62A is provided between the directional auxiliary slider 62 and the mounting body 1. When the wheel system is in the directional state, both the first reset spring 61A and the second reset spring 62A are in a compressed state.

[0065] Furthermore, such as Figures 8-12 and combined Figures 5-6As shown, the transmission mechanism 6 in this embodiment also includes a pause slider 63, a pause turntable 64, and a fixed base 65. The fixed base 65 is fixedly mounted on the mounting body 1, meaning it is stationary and does not move during operation. The pause slider 63 is retractably mounted on the fixed base 65, and a push shaft extends from the pause slider 63. This push shaft movably abuts against the inclined surface on the pedal 10. The pedal 10 can push the push shaft through the inclined surface, causing the pause slider 63 to retract on the fixed base 65. The pause turntable 64 is movably mounted on the fixed base 65 and movably abuts against the pause slider 63 and the directional slider 61, respectively. It should be explained that the names pause slider 63 and pause turntable 64 are used because the cooperation between the pause slider 63, pause turntable 64, and fixed base 65 allows the wheel system to temporarily remain in the directional state when switched to the directional state, without resetting to the non-directional state.

[0066] In actual use, when the pedal 10 is pressed to switch the wheel system to the directional state, the pause turntable 64 can be restricted to the fixed base 65, preventing the directional slider 61 from resetting, so that the wheel system remains in the directional state. Specifically, the fixed base 65 has an abutment slope 650 at its end. When the pause turntable 64 abuts against the abutment slope 650, the pause turntable 64 restricts the reset of the directional slider 61, keeping the wheel system in the directional state. At this time, the pause turntable 64 cannot retract towards the fixed base 65, as it is stopped and limited by the abutment slope 650 on the fixed base 65.

[0067] The fixed base 65 has a slot 651, and the pause turntable 64 has multiple locking blocks 640 along its circumference. When the wheel system is in the oriented state, the locking blocks 640 disengage from the slot 651 and abut against the abutment ramp 650 on the fixed base 65. When the wheel system switches to the non-oriented state, the locking blocks 640 engage with the slot 651, meaning the pause turntable 64 can retract towards the fixed base 65. At this time, the oriented slider 61 can return to its initial position because the pause turntable 64 no longer restricts the oriented slider 61 from resetting. In this embodiment, the pause slider 63 has multiple first ramps 630, which are used to press the pause turntable 64, forcing it to rotate. The pause turntable 64 has a second ramp 641, and the pause slider 63 can push against the second ramp 641 through the first ramp 630, causing the pause turntable 64 to rotate.

[0068] In practical use, this embodiment uses the cooperation of the pause slider 63, the fixed seat 65, and the pause turntable 64 to form an automatic ballpoint pen telescopic mechanism. This allows the wheel system to remain in the oriented state after switching to the oriented state, ensuring structural stability. The cooperation of these three components also allows the wheel system to remain in the non-oriented state after resetting to the non-oriented state. Since the automatic ballpoint pen telescopic mechanism is existing technology, it will not be described in detail here.

[0069] The working principle of the dual-directional wheel system in this embodiment is as follows:

[0070] like Figure 5 As shown, when the wheel system is in an unoriented state, the first directional locking pin 4 is not locked into the locking groove 231 of the first wheel 2, and the second directional locking pin 5 is not locked into the locking groove 231 of the second wheel 3. The first wheel 2 and the second wheel 3 can rotate freely along their respective axles 230-360 degrees. At this time, the pause slider 63 and the pause turntable 64 are located near the directional foot pedal side, and the locking block 640 on the pause turntable 64 is locked in the locking groove 651 on the fixed seat 65. When dual orientation is required, pressing pedal 10 pushes the pause slider 63 against the inclined plane, causing the pause slider 63 to move to the right, closer to the first wheel 2. The pause slider 63 drives the pause turntable 64 to move to the right, which in turn drives the orientation slider 61 to move to the right. Meanwhile, the orientation slider 61, through the dual orientation cable 612, drives the orientation auxiliary slider 62 to move to the left. At this time, the rightward movement of the orientation slider 61 relaxes the first cable 610, and the leftward movement of the orientation auxiliary slider 62 relaxes the second cable 620. Under the action of the first tension spring 40 and the second tension spring 50, the first orientation locking pin 4 and the second orientation locking pin 5 lock into the locking grooves 231 of the first wheel 2 and the second wheel 3 respectively, completing the synchronous dual orientation of the first wheel 2 and the second wheel 3. Figure 6 As shown. At this time, the locking block 640 on the pause turntable 64 disengages from the locking groove 651 on the fixed seat 65, and the pause turntable 64 abuts against the abutting inclined surface 650 on the fixed seat 65, so that the pause turntable 64 cannot retract to the fixed seat 65 side, restricting the directional slider 61 from resetting, and the directional auxiliary slider 62 is also restricted from resetting, so that the wheel system remains in a dual-directional state. When it is necessary to release the dual orientation, the pedal 10 is pressed, which causes the pause slider 63 to move to the right. The pause slider 63 pushes against the pause turntable 64 through the first inclined surface 630, causing the pause turntable 64 to rotate. The locking block 640 on the pause turntable 64 re-engages into the locking groove 651 on the fixed seat 65. At this time, the pause turntable 64 can retract towards the fixed seat 65, no longer restricting the reset of the orientation slider 61. Under the action of the first reset spring 61A and the second reset spring 62A, the orientation slider 61 and the orientation auxiliary slider 62 reset, respectively re-tightening the first orientation locking pin 4 and the second orientation locking pin 5. The first orientation locking pin 4 and the second orientation locking pin 5 disengage from the locking groove 231 of the first wheel 2 and the second wheel 3, respectively, and the dual orientation is released.
