[0010] By implementing the above technical solution, when a person pushes the push rod assembly, the thumb will fall on the unlocking button, which is convenient for the person to operate the unlocking. The provision of the protective part prevents the unlocking button from malfunctioning and causing the frame to be unlocked and folded, thereby ensuring the reliability of the frame.

[0011] As a preferred solution of the present application, the protective member includes a safety pin, a clip-on groove for inserting the safety pin is provided on the side wall of the unlocking button, an elastic member for inserting the safety pin into the clip-on groove is provided between the seat post assembly and the safety pin, and a driving member for driving the safety pin to disengage from the clip-on groove is provided on the seat post assembly.

[0012] To implement the above technical solution, when there is no external force, the safety pin is inserted into the unlocking button under the action of the spring, thereby preventing the unlocking button from malfunctioning.

[0013] As a preferred solution of the present application, the driving member includes a driving slider slidably set on the push rod assembly, the driving slider is set below the safety pin, the driving slider is provided with a driving surface inclined downward in a direction away from the unlocking button, and the safety pin is provided with a guide surface that fits with the driving surface.

[0014] To implement the above technical solution, when a person holds the push rod assembly, his thumb will automatically fall on the unlocking button, and the other fingers will press on the driving slider. When unlocking is required, it is only necessary to squeeze and press the driving block to move the driving block upward, thereby driving the safety pin away from the unlocking button, thereby achieving the unlocking effect.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When the frame is unfolded, it is only necessary to lift the push rod assembly upward, thereby driving the seat rod assembly to rotate around the bracket assembly to open. When the seat rod assembly rotates upward, it will pull and rotate upward, so that the push rod assembly is engaged in the locking groove, thereby completing the unfolding and locking of the frame, and no unnecessary unfolding steps are required, thereby improving the convenience of the user. When it is necessary to fold it up, it is only necessary to unlock the locking piece through the unlocking assembly, so that the push rod assembly can rotate around the connecting rod and drive the connecting rod itself around the bracket assembly, thereby achieving automatic folding. The seat rod assembly, the push rod assembly and the connecting rod are close to the bracket assembly, thereby achieving the effect of automatic folding, which is convenient for personnel to operate;

[0017] 2. When a person pushes the push rod assembly, the thumb will fall on the unlocking button, which is convenient for the person to operate the unlocking. The setting of the protective part can prevent the unlocking button from malfunctioning and causing the frame to be unlocked and folded, thereby ensuring the reliability of the frame.

[0024] The following is combined with Figure 1-4 This application is described in further detail.

[0025] The present application embodiment discloses a folding child bicycle frame. Figure 1 The foldable child bicycle frame comprises a bracket assembly 1, a seat rod assembly 2, a push rod assembly 3 and a connecting rod 4.

[0026] One end of the seat rod assembly 2 is hinged to one end of the bracket assembly 1, the connecting rod 4 is hinged to the bracket assembly 1, the push rod assembly 3 is hinged to the seat rod assembly 2, the push rod assembly 3 is hinged to the connecting rod 4, and the connecting rod 4 is provided with a locking groove for the push rod assembly 3 to be clamped. A locking member is provided between the connecting rod 4 and the push rod assembly 3, and the locking member is provided at the locking groove, wherein the locking member can use a locking mechanism commonly used on the market, such as a pull rope type locking mechanism (refer to CN109625070A), or an electric drive type locking mechanism, etc., such as an elastic tongue is provided on the push rod assembly 3, and a positioning groove for the elastic tongue to be inserted is provided on the locking groove, that is, the positioning push rod assembly 3 and the connecting rod 4 are locked by inserting the elastic tongue into the positioning groove. The push rod assembly 3 is provided with an unlocking assembly 5 for driving the locking member to unlock. If it is a pull-rod type locking mechanism, the unlocking assembly 5 is used to drive the pull rope to move, so that the tongue is disengaged from the positioning groove, thereby completing the unlocking. If it is an electric-driven locking mechanism, it is used to drive the electric-driven member to start, thereby achieving the unlocking effect.

[0027] That is, when the frame is unfolded, it is only necessary to lift the push rod assembly 3 upwards, thereby driving the seat rod assembly 2 to rotate around the bracket assembly 1 to open, and when the seat rod assembly 2 rotates upwards, it will pull and rotate upwards, so that the push rod assembly 3 is engaged in the locking groove, thereby completing the unfolding and locking of the frame, and no unnecessary unfolding steps are required, thereby improving the convenience of the user. When it is necessary to fold, it is only necessary to unlock the locking member through the unlocking assembly 5, so that the push rod assembly 3 can rotate around the connecting rod 4, and drive the connecting rod 4 itself around the bracket assembly 1, thereby achieving automatic folding, and the seat rod assembly 2, the push rod assembly 3 and the connecting rod 4 are close to the bracket assembly 1, thereby achieving the effect of automatic folding, which is convenient for personnel to operate.

[0028] The unlocking assembly 5 includes an unlocking button 51 for unlocking the locking member. A sliding groove for the unlocking button 51 to slide is provided on the top of the push rod assembly 3, so that when a person pushes the push rod assembly 3, the thumb will fall on the unlocking button 51, which is convenient for the person to operate the unlocking. In order to prevent the unlocking button 51 from malfunctioning, a protective member is provided on the push rod assembly 3. The protective member includes a safety pin 52. A clamping groove for inserting the safety pin 52 is provided on the side wall of the unlocking button 51. An elastic member 53 for inserting the safety pin 52 into the clamping groove is provided between the seat rod assembly 2 and the safety pin 52. The elastic member 53 is a spring. A driving member for driving the safety pin 52 to disengage from the clamping groove is provided on the seat rod assembly 2. That is, in the absence of external force, the safety pin 52 is inserted into the unlocking button 51 under the action of the spring, thereby preventing the unlocking button 51 from malfunctioning.

[0029] The driving member includes a driving slider 54 slidably arranged on the push rod assembly 3, the driving slider is arranged below the safety pin 52, the driving slider is provided with a driving surface inclined downward in a direction away from the unlocking button 51, and the safety pin 52 is provided with a guide surface that fits the driving surface. That is, when a person holds the push rod assembly 3, his thumb will automatically fall on the unlocking button 51, and the other fingers will hold and press on the driving slider 54. When unlocking is required, it is only necessary to hold and press the driving block to move the driving block upward, thereby driving the safety pin 52 away from the unlocking button 51, so as to achieve the unlocking effect. That is, the frame in this solution can be temporarily opened or folded all at once, and the setting of the unlocking assembly 5 can ensure the reliability of the frame, and the folding situation will not occur due to misoperation.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
