[0038] like Figure 1 As shown, this embodiment provides a baby stroller bracket assembly, which mainly includes a bracket body fixing seat 21, a fixing box 22, a first bracket 23, a second bracket 24, and a bracket locking assembly.

[0039] The bracket body fixing base 21 serves as the foundation for the installation and support of other components. The fixing box 22 is connected to the bracket body fixing base 21.

[0040] The first bracket 23 is rotatably connected to the bracket body fixing seat 21, and the center position of the relative rotation between the first bracket 23 and the bracket body fixing seat 21 is the first position 101;

[0041] The second bracket 24 is rotatably connected to the bracket body fixing seat 21. The center position of the relative rotation between the second bracket 24 and the bracket body fixing seat 21 is the second position 102. The first position 101 and the second position 102 are different.

[0042] The first support 23 and the second support 24 are arranged in a rotatable connection mode with the support body fixing seat 21, so that the stroller is folded by rotating the first support 23 and the second support 24.

[0043] As shown in Figure 2 , the support locking assembly in the embodiment includes a first locking piece 25 and a second locking piece 26, the first locking piece 25 is fixedly connected with the first support 23, the second locking piece 26 is rotatably connected with the support body fixing seat 21, the first locking piece 25 is provided with a first locking hook 251 and a first hook groove 252, and the second locking piece 26 is provided with a second locking hook 261 and a second hook groove 262.

[0044] As shown in Figure 3 , the first locking piece 25 can be fixed with the first support 23 by a rivet to form an integral structure and rotate synchronously with the first support 23.

[0045] The stroller in the embodiment has at least two states, namely an unfolded state and a folded state, and the unfolded state is also referred to as a first state, and the folded state is also referred to as a second state.

[0046] As shown in Figure 4 , when the stroller support assembly is in the first state, the first locking hook 251 is clamped into the second hook groove 262, and the second locking hook 261 is clamped into the first hook groove 252.

[0047] Since the locking hooks and the hook grooves of the first locking piece 25 and the second locking piece 26 are clamped with each other, the first locking piece 25 and the second locking piece 26 are in a locked state and cannot rotate relative to each other, and since the first locking piece 25 is fixedly connected with the first support 23, the first support 23 cannot rotate, and the stroller can be kept in a stable unfolded state to ensure that the stroller can be safely used.

[0048] As shown in Figure 6 , when the stroller support assembly is in the second state, the first locking piece 25 and the second locking piece 26 are separated from each other.

[0049] As shown in Figure 5 , when the stroller needs to be folded, the second locking piece 26 can be rotated to a state where the first locking piece 25 and the second locking piece 26 are separated from each other, that is, the first locking hook 251 is withdrawn from the second hook groove 262, and the second locking hook 261 is withdrawn from the first hook groove 252, at this time, the first locking piece is no longer constrained by the second locking piece, and the first support 23 can rotate relative to the support body fixing seat 21, thereby facilitating folding of the stroller.

[0050] As shown in Figure 7As shown in the drawings, the baby folding stroller support assembly of the embodiment further comprises a joint connecting piece 27, one end of which is rotatably connected with the first support 23, and the opposite end is rotatably connected with the second support 24. The position where the joint connecting piece 27 is rotatably connected with the first support 23 is the third position, and the position where the joint connecting piece 27 is rotatably connected with the second support 24 is the fourth position. The third position is different from the first position, the second position and the fourth position, and the fourth position is different from the first position and the second position.

[0051] The first support 23 and the second support 24 are connected by the joint connecting piece 27, so that the first support 23 and the second support 24 can be linked. When the baby folding stroller support assembly needs to be folded, the first support 23 is rotated to rotate around the first position, and the first support 23 drives the joint connecting piece 27 to rotate, and the joint connecting piece 27 drives the second support 24 to rotate around the second position, so that the first support 23 and the second support 24 rotate towards each other to drive the baby folding stroller to fold.

[0052] As shown in the drawings, Figure 8 The baby folding stroller support assembly of the embodiment further comprises a wrench 28, which is rotatably connected with the second locking piece 26. As shown in the drawings, Figure 9 to Figure 11 The wrench 28 can be rotated to conveniently adjust the angular position of the second locking piece 26, so that the locking assembly is in the locked state or the unlocked state. The position of the wrench 28 corresponding to the locked state, Figure 9 The position of the wrench 28 corresponding to the unlocking moment, Figure 10 The position of the wrench 28 corresponding to the folded state. Figure 11

[0053] As shown in the drawings, Figure 8 In the embodiment, the wrench 28 and the second locking piece 26 are rotatably connected with the support body fixing seat 21 by a first pin, and the second locking piece 26 and the wrench 28 are connected as a whole by a second pin.

[0054] As shown in the drawings, Figure 1 The baby folding stroller support assembly of the embodiment further comprises a first torsional spring 291, one end of which is connected with the fixing box 22, and the other end is connected with the first support 23. When the baby folding stroller support assembly is in the first state, the first torsional spring 291 is elastically deformed. When the baby folding stroller is converted from the folded state to the unfolded state, the first support 23 is rotated in the process, overcoming the elastic force of the first torsional spring 291, so that the first torsional spring 291 is elastically deformed. When the baby folding stroller is converted from the unfolded state to the folded state, the first torsional spring 291 drives the first support 23 to rotate to the folded position. ​

[0055] As Figure 2 shown, the baby stroller support assembly of the embodiment further comprises a second torsion spring 292, one end of which is connected with the fixed box 22 and the other end of which is connected with the second support 24. The second torsion spring 292 is elastically deformed when the baby stroller support assembly is in the first state. When the baby stroller is converted from the folded state to the unfolded state, the second support 24 overcomes the elastic force of the second torsion spring 292 during rotation, so that the second torsion spring 292 is elastically deformed. When the baby stroller is converted from the unfolded state to the folded state, the second torsion spring 292 drives the first support 23 to rotate to the folded position.

[0056] The installation of the first torsion spring 291 and the second torsion spring 292 can adopt the following manner:

[0057] The first support 23 is provided with a first mounting hole, one end of the first torsion spring 291 is inserted into the first mounting hole, and the other end is connected with the first fixed column of the fixed box 22. The second support 24 is provided with a second mounting hole, one end of the second torsion spring 292 is inserted into the second mounting hole, and the other end is connected with the second fixed column of the fixed box 22.

[0058] As Figure 1 and Figure 8 shown, the baby stroller support assembly of the embodiment further comprises a stowing reset spring 293, one end of which abuts against the wrench 28 and the other end of which abuts against the support body fixing seat 21. The stowing reset spring 293 is used to reset the wrench 28, so as to drive the second locking member 26 to reset, so as to ensure that the support locking assembly can be reliably locked.

[0059] As Figure 1 shown, the baby stroller support assembly of the embodiment further comprises a fixing member 294, which is connected with two parts separated above the support body fixing seat 21, so as to increase the stability of the structure, maintain sufficient clearance in the internal space, and enable the first support 23 and the second support 24 to rotate freely. The fixing member 294 is provided with a first guide groove and a second guide groove. The first support 23 is provided with a first guide part, at least a part of which is located in the first guide groove. The second support 24 is provided with a second guide part, at least a part of which is located in the second guide groove.

[0060] The first and second guides can be arranged in a ring shape. In order to further provide reliability and stability, a plurality of guide grooves and guides can be arranged, and the first and second guides are arranged alternately. Embodiment

[0061] The present embodiment also provides a baby folding stroller, which comprises the baby folding stroller support assembly described in Embodiment 1. The overall frame of the stroller is shown in Figure 12

[0062] Since the baby folding stroller of the present embodiment adopts the baby folding stroller support assembly described in Embodiment 1, the reliable fixation in the unfolded state can be achieved by the cooperation of the locking hooks and the hook grooves of the first and second locking members 25 and 26, and only the second locking member 26 needs to be rotated to be unlocked during folding, which is simple to operate. Since only the second locking member 26 needs to be rotated, the first and second locking hooks 251 and 261 are withdrawn from the hook grooves, respectively, so that the first support 23 can be unlocked and rotated relative to the support main body fixing seat 21, and the folding operation is completed, so that the folding process is simple. During unfolding, the hook grooves of the locking assembly are automatically connected with the locking hooks, without the need for additional operation, which ensures that the stroller can quickly return to the use state.

[0063] The folding and unfolding processes of the baby folding stroller are described below.

[0064] Folding process:

[0065] Unlocking: rotating the wrench 28 to rotate the second locking member 26, so that the first locking hook 251 is separated from the second hook groove 262, and the second locking hook 261 is separated from the first hook groove 252, thereby releasing the interlocking state of the support locking assembly.

[0066] Support linkage folding: the first support 23 rotates around the first position under the action of the first torsion spring 291 and gravity, and the second support 24 rotates synchronously and reversely around the second position under the action of the second torsion spring 292 and gravity. The first and second torsion springs 291 and 292 release the stored elastic potential energy, and assist in driving the first and second supports 24 to fold and shrink towards each other.

[0067] Trajectory constraint: the guide grooves of the fixing member 294 cooperate with the support guides to ensure that the support rotates strictly around the shaft and avoids deviation and jamming.

[0068] Unfolding process:

[0069] ​Pulling the first support 23 to unfold outwardly, the first support 23 drives the second support 24 to unfold outwardly through the joint connector 27, overcoming the elastic resistance of the first and second torsional springs 292, and forcing the support to rotate around the shaft to the unfolded position.

[0070] Automatic locking: when the support is in place, the first locking hook 251 and the second hook groove 262, and the second locking hook 261 and the first hook groove 252 are automatically engaged and locked under the action of the folding reset spring 293.

[0071] The torsional spring recharges energy, providing assistance for the next folding.

[0072] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the system, module and unit described above can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
