[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0036] like Figure 1 As shown, in this solution, a foldable pedal device for a baby stroller is mainly described in detail, but the foldable pedal device is not limited to being used in a baby stroller, and can also be applied to other places, such as bicycles, etc.

[0037] like Figures 1 to 6 As shown, the utility model is a foldable foot pedal device, comprising: a foldable block 2, which is movably connected to a frame 1 and can be switched between a first position and a second position of the frame 1; a locking member 3, which is arranged in the foldable block 2, and the locking member 3 is movably inserted in the frame 1, so as to limit the foldable block 2 to the first position or the second position; a foot pedal 4, which is rotatably connected to the two side walls of the foldable block 2, and the foot pedal 4 can be folded and stored relative to the foldable block 2; when the foldable block 2 is in the first position, the foldable block 2 is arranged at an angle with the frame 1, so that the foot pedal 4 can be in a horizontal posture for support of the foot; when the locking member 3 is unlocked, the foldable block 2 can be switched from the first position to the second position, so that the foldable block 2 is close to the bottom of the frame 1, and the foot pedal 4 is folded and stored along the direction of the foldable block 2.

[0038] This solution is mainly aimed at further realizing the folding and storage of the pedal device on the basis of the foldable storage of some rear wheels. For details, refer to Figures 1 to 3 When the baby stroller is in use, the folding block 2 movably connected to the frame 1 is in Figure 1 or Figure 2The folding block 2 is placed vertically at this time. Since the footrests 4 on both sides are also rotatably connected to the folding block 2, the footrests 4 can be placed in a vertical position by relying on the gravity of the footrests 4 and the rotational force applied by the user around the folding block 2. Figure 1 or Figure 2 The horizontal posture shown in the figure allows the user to place his feet on the footrest 4 for leisure and relaxation, providing convenience; after the locking member 3 unlocks the folding block 2, the folding block 2 can drive the footrest 4 to move upward. Figure 2 Switch to Figure 3 In the position shown in the figure, the folding block 2 is now closely attached to the bottom of the frame 1, and the footrest 4 is closely attached to the two side walls of the folding block 2 after rotating relative to the folding block 2, thereby achieving the effect of folding and storing, saving the space occupied by the entire footrest device, and facilitating the storage or carrying of the device when not in use, and the locking member 3 locks the folding block 2, effectively ensuring that the folding block 2 is in a Figure 2 or Figure 3 It can maintain stability when in the shown position, thereby improving the customer's user experience.

[0039] The locking member 3 includes: a locking block 30, a mounting cavity 20 arranged vertically is formed in the folding block 2, the locking block 30 is movably arranged in the mounting cavity 20, and is movably inserted into the frame 1; an elastic member 31, which is located at the bottom of the locking block 30, and a guide portion 300 is formed at the bottom of the locking block 30, one end of the elastic member 31 is connected to the bottom wall of the mounting cavity 20, and the other end is sleeved on the guide portion 300 and connected to the locking block 30.

[0040] The locking member 3 in this solution determines the stability of the folding block 2 when it is in the first position or the second position. Specifically, Figure 4 and Figure 6 As shown, the locking member 3 is mainly composed of a locking block 30 and an elastic member 31. When the folding block 2 is in Figure 2 When the locking block 30 is in the position shown in FIG. 1 , the locking block 30 extends out of the mounting cavity 20 and is movably inserted into the frame 1 by virtue of the elastic reset capability of the elastic member 31. Figure 4 At this time, the frame 1 restricts the locking block 30, so that the folding block 2 cannot rotate relative to the frame 1, thereby achieving the function of locking the pedal device; when the user applies an extrusion force on the locking block 30 along the direction of the elastic member 31, the elastic member 31 is gradually squeezed and contracted by the locking block 30, and the locking block 30 can be separated from the frame 1. After the folding block 2 is no longer restricted by the frame 1, it can be moved out. Figure 2 Position rotated to Figure 3The locking block 30 is in the position shown in the figure, and when the user releases the squeezing force on the locking block 30, the locking block 30 can be reinserted into the frame 1 by relying on the elastic deformation force of the elastic member 31, so as to ensure the stability of the foot pedal device after folding and storage. The overall structure of the locking member 3 is relatively simple, which is conducive to the user to quickly realize the folding and storage function of the foot pedal device under convenient operation.

[0041] Preferably, the elastic member 31 in this solution can be replaced by a compression spring, a return spring or other elastic members 31 .

[0042] A fixing block 10 is detachably connected to the frame 1, the folding block 2 is hinged to the fixing block 10, and a first locking groove 100 and a second locking groove 101 arranged at an angle are formed on the fixing block 10, and the locking block 30 is movably inserted in the first locking groove 100 or the second locking groove 101.

[0043] Continue to refer Figure 4 The frame 1 is detachably connected with a fixing block 10, which provides convenience for the installation of the pedal device. Since the first locking groove 100 and the second locking groove 101 on the fixing block 10 are crucial to the locking of the folding block 2, the fixing block 10 can be removed and replaced in time after the locking groove is damaged, which provides a guarantee for the stability of the pedal device during use; and the first locking groove 100 and the second locking groove 101 set at an angle can respectively limit and fix the folding block 2 at Figure 2 and Figure 3 It should be noted that the positions of the first locking groove 100 and the second locking groove 101 on the fixing block 10 can be adaptively adjusted according to the actual use requirements of the customer, for example, Figure 2 When the footrest 4 shown is slightly tilted to improve the footrest comfort, the angle between the first locking groove 100 and the second locking groove 101 can be increased during production to meet the usage requirements of customers.

[0044] Preferably, as long as the folding plate is accurately Figure 2 The first position shown or Figure 3 When in the second position shown, the elastic deformation force of the elastic member 31 can be utilized to ensure that the locking block 30 is accurately inserted into the first locking groove 100 or the second locking groove 101 during the resetting process, thereby completing the stable locking of the pedal device.

[0045] A locking portion 302 is formed on the locking block 30 , and a limiting groove 25 is formed on the top of the folding block 2 . The limiting groove 25 is connected to the installation cavity 20 so that the locking portion 302 can pass through the limiting groove 25 and be movably inserted in the first locking groove 100 or the second locking groove 101 .

[0046] like Figures 4 to 6 As shown, the limiting groove 25 opened at the top of the folding block 2 is connected to the installation cavity 20. It is worth noting that since the locking block 30 is movably arranged in the installation cavity 20, the installation cavity 20 can be used to guide the reciprocating movement of the locking block 30, ensuring that the locking portion 302 at its end can be accurately inserted into the first locking groove 100 or the second locking groove 101; and because the volume of the locking block 30 is larger than the volume of the locking portion 302 and the size of the limiting groove 25, the limiting groove 25 can limit the locking block 30. Figure 4 As shown, the limiting groove 25 can only allow the locking portion 302 to pass through and be inserted in the first locking groove 100 or the second locking groove 101, that is, the distance that the locking block 30 moves along the direction of the frame 1 is limited. In conjunction with the above-mentioned elastic member 31 that is sleeved on the guide portion 300 at the bottom of the locking block 30, the smoothness and stability of the locking and unlocking functions of the pedal device are further improved.

[0047] It should be added that the size of the locking groove is slightly larger than the locking portion 302 on the locking block 30, which ensures that the locking portion 302 is stably inserted in the locking groove and can also limit the movement of the locking portion 302 by using the locking groove, effectively avoiding the folding block 2 from being in a Figure 2 or Figure 3 When the vehicle body is in the position, it will shake relative to the frame 1.

[0048] A through hole 22 and a detachably connected cover plate 23 are formed on the folding block 2. A fixing column 24 is extended along the inside of the folding block 2. A threaded hole 240 is provided in the fixing column 24. When the threaded hole 240 is aligned with the through hole 22, the cover plate 23 is connected to the folding block 2 through a fixing member to prevent external dust and impurities from entering the installation cavity 20.

[0049] like Figure 5 and Figure 6 As shown, since the locking block 30 and the elastic member 31 are both arranged in the installation cavity 20, the installation cavity 20 can be sealed by the cover plate 23, which effectively prevents the entry of dust and impurities from the outside and affects the smoothness of the folding and storage process of the pedal device. At the same time, the detachable design also provides convenience for the subsequent maintenance and replacement of the locking block 30 or the elastic member 31, extending the service life of the pedal device. During the installation of the cover plate 23, it is only necessary to cover the cover plate 23 on the opening end of the installation cavity 20 so that the threaded hole 240 on the cover plate 23 is aligned with the through hole 22 on the folding block 2, so that the worker can connect the cover plate 23 with the folding block 2 by passing the fixing member through the through hole 22 and the threaded hole 240. This installation method is convenient and quick to operate, which is conducive to improving the installation efficiency of the workers. It should be noted that the fixing member in this solution can be replaced by screws, countersunk studs or other fixing members.

[0050] The side wall of the locking block 30 is formed with a snap-fit ​​block 301 . The cover plate 23 is provided with a guide groove 230 . The snap-fit ​​block 301 is movably snap-fitted in the guide groove 230 to control the locking block 30 to lock or unlock the folding block 2 .

[0051] like Figure 2 As shown, after the cover plate 23 is installed and connected to the folding block 2, the guide groove 230 on the cover plate 23 is movably engaged with the locking block 301 on the locking block 30, which further guides and limits the reciprocating movement of the locking block 30 in the installation cavity 20, effectively ensuring the smoothness and stability of the locking block 30 in the process of unlocking or locking the folding block 2.

[0052] like Figure 5 As shown, in this solution, a clearance groove 26 is formed on the folding block 2. Figure 2 The displayed position switches to Figure 3 In the position shown, since the fixing block 10 connected to the frame 1 has a small portion extending outward on both sides, it is convenient to install the fixing block 10 on the frame 1 by screws, which also makes it impossible for the folding block 2 to be tightly attached to the bottom of the frame 1. The design of the clearance groove 26 can avoid position interference between it and the fixing block 10, effectively ensuring that the folding block 2 is folded to Figure 3 In the second position shown, the bicycle can be closely attached to the bottom of the bicycle frame 1, so as to achieve the desired folding and storage effect.

[0053] Preferably, the locking block 30 in this solution is also provided with a plurality of weight-reducing holes 32, such as Figure 4 As shown, the weight-reducing hole 32 can reduce the weight of the locking block 30 as a whole, reduce the use of materials, and effectively avoid the pedal device being in a Figure 2 In the position shown, the locking block 30 is disengaged from the locking groove due to its own greater weight, resulting in a phenomenon of mis-locking.

[0054] The end of the folding block 2 away from the frame 1 extends outward to form a connecting portion 21 , and a connecting hole 40 is provided on the footrest 4 . The connecting shaft 5 passes through the connecting hole 40 and the connecting portion 21 , so that the footrest 4 is hinged on the folding block 2 .

[0055] Regarding the connection between the foot pedals 4 on both sides of the folding block 2, it should be noted that the connecting portion 21 is also provided with a connecting hole 40 (not shown in the figure) which is the same as that on the foot pedal 4. Therefore, when the connecting portion 21 is aligned with the connecting hole 40 on the foot pedal 4, the worker can flexibly connect the two together through the connecting shaft 5, so that the foot pedal 4 can achieve the effect of folding and storage after rotating relative to the folding block 2.

[0056] Preferably, the surface of the foot pedal 4 in this solution can be provided with an uneven anti-slip surface, so as to ensure that after the user places his foot on the foot pedal 4, the friction between the two is increased to improve the safety performance of the foot pedal device.

[0057] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0058] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
