Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 As shown, the present utility model is an adjustable-angle baby carriage base, including a base plate 1. A fixed hinge 6 is fixedly connected to the middle of the upper end of the base plate 1. A movable hinge 7 is rotatably connected to the fixed hinge 6. A rotating plate 8 is fixedly installed on the movable hinge 7; A drive box 3 is fixedly installed at the lower end of the base plate 1. A driving member 4 is installed at the drive box 3. The driving member 4 is connected to a driving connection 9. The driving connection 9 is connected to the rotating plate 8 through a connecting support 10. A driving rotating handle 5 is connected to the driving member 4.

[0028] Further, a plurality of mounting holes are provided on the rotating plate 8 for mounting the baby carriage body. By driving the driving member 4 to rotate through the driving rotating handle 5, the driving member 4 drives the driving connection member 9 to drive the rotating plate 8. The rotating plate 8 can rotate around the fixed hinge 6 to complete the adjustment of the height of the baby carriage body.

[0029] At the four corners of the lower end of the base plate 1, foot pads 2 are fixedly installed. The height of the foot pads 2 is greater than the height of the drive box 3, so that there is enough installation space for the drive box 3, and the drive box 3 will not be in direct contact with the ground, which may affect the internal structure thereof.

[0030] Furthermore, the foot pads 2 are made of rubber pads with certain elastic properties. This not only improves the friction with the ground to enhance the stability of the stroller placement, but also the elastic rubber pads can effectively reduce the impact of external vibrations on the stroller, ensuring that the baby can maintain a quiet sleeping environment.

[0031] The drive box 3 includes a box body 32. An annular box connecting plate 31 is arranged on the outer periphery of the opening of the box body 32. The box connecting plate 31 is fixedly installed at the lower end of the base plate 1. A guiding cavity 34 for installing the driving member 4 is arranged in the box body 32. The annular box connecting plate 31 ensures the stability of the installation of the drive box 3. At the same time, a through groove for avoiding the drive connection 9 is arranged on the base plate 1, so as to transmit the drive at the bottom to the upper end of the base plate 1 to complete the drive for the rotation of the rotating plate 8.

[0032] The driving member 4 includes a main driving shaft 41. The main driving shaft 41 rotatably penetrates through one side wall of the box body 32. One end of the main driving shaft 41 located outside the box body 32 is fixedly connected to the driving turning handle 5. The other end of the main driving shaft 41 is fixedly connected to a threaded rod 44. A bearing rod 45 rotatably connected to the box body 32 is fixedly arranged at the end of the threaded rod 44 away from the main driving shaft 41.

[0033] A bearing cavity 33 is arranged in the box body 32. A bearing seat connected to the bearing rod 45 is fixedly installed in the bearing cavity 33. The main driving shaft 41 of the driving member 4 is rotatably installed through the bearing cavity 33 and the bearing seat, so as to ensure the stability of the connection between the driving member 4 and the drive box 3.

[0034] A limiting baffle 42 is fixedly arranged on the outer periphery of the main driving shaft 41. A limiting cavity 35 matched with the limiting baffle 42 is arranged in the box body 32. Through the cooperation of the limiting baffle 42 and the limiting cavity 35, a limiting effect is exerted on the installation connection between the driving member 4 and the drive box 3 to prevent the main driving shaft 41 from sliding on the drive box 3. And since the height of the limiting baffle 42 is higher than the upper surface of the box body 32, a slot hole for avoiding the limiting baffle 42 is arranged on the base plate 1.

[0035] A plurality of grooves 43 are uniformly arranged on the outer periphery of the main driving shaft 41. When the rotating plate 8 needs to be rotationally driven, the driving member 4 is driven to rotate by rotating the driving turning handle 5. Therefore, the driving member 4 needs to maintain sufficient strength. The arrangement of the grooves 43 effectively reduces the overall weight of the driving member 4, making the rotational drive of the driving member 4 more labor-saving.

[0036] The driving connection 9 includes a threaded seat 91, the threaded seat 91 is threadedly connected to the threaded rod 44 and slidably connected in the guiding cavity 34. Two sets of connecting rod supports 92 are fixedly arranged on the threaded seat 91. A driving connecting rod 93 is rotatably connected to the connecting rod support 92, and the driving connecting rod 93 is rotatably connected to the connecting seat 10. Specifically, a groove that rotatably cooperates with the driving connecting rod 93 is arranged on the connecting seat 10.

[0037] Limit insertion plates 94 for connecting and limiting the connecting seat 10 are arranged at both ends of the driving connecting rod 93. The limit insertion plates 94 prevent the driving connecting rod 93 from falling off the connecting seat 10, and at the same time play a role in positioning the connection of the driving connecting rod 93, preventing the driving of the rotating plate 8 from tilting due to the offset of the driving connecting rod 93, and improving the overall driving stability.

[0038] The working principle of the present utility model: By rotating the driving handle 5 to drive the driving member 4 to rotate, wherein the threaded rod 44 rotates, and drives the threaded seat 91 to reciprocally slide along the guiding cavity 34 through the screw drive principle. The threaded seat 91 drives the driving connecting rod 93 to rotate. Under the limiting action of the fixed hinge 6 and the movable hinge 7, the rotating plate 8 is driven to rotate along the fixed hinge 6, thereby realizing the adjustment of the height of the baby carriage body.

[0039] One embodiment of the present utility model has been described in detail above, but the content described is only the preferred embodiment of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
