Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steering wheel horn button circuit boards, in particular to a button circuit board for a steering wheel horn of a baby carriage. Background Art
[0002] Children's electric cars are motor-driven toy cars that children can drive and sit on. Children's electric cars usually come with a remote control that can be controlled by parents. Children can also control the car themselves using the accelerator pedal, but parents are still required to supervise the car to ensure safety.
[0003] At present, the steering wheels of baby strollers are generally disc-shaped, and the internal horn button circuit boards also adopt a fixed plate type to adapt to the disc structure. However, with the continuous improvement of the styles and functions of baby strollers, special-shaped steering wheels have gradually appeared, and the horn button circuit boards in the steering wheels cannot meet the adaptation requirements of existing steering wheels of different shapes. In order to adapt to the steering wheels, a set of steering wheel horn button circuit boards has been developed. Utility Model Content
[0004] The purpose of the utility model is to provide a key circuit board for a steering wheel horn of a baby carriage to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A button circuit board for a baby car steering wheel horn comprises a circuit board, buttons are arranged on the left and right sides and the bottom of the circuit board, arc grooves are opened around the circuit board, a wiring port is arranged on the upper end of the back side of the circuit board, and the back side of the button is electrically connected to the connection pin.
[0007] As a further solution of the present invention, the circuit connection relationship between the buttons is a parallel connection.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. When the utility model is used, a circuit board with an arc groove and a horn button connected in parallel are provided, so that the key circuit board can be adapted to the opposite-sex steering wheel. At the same time, three buttons are connected in parallel to realize the reception of the pressing signal in all directions without dead angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0014] In the present utility model, the word "exemplary" is used to mean "used as an example, illustration or description". Any embodiment described as "exemplary" in the present utility model is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present utility model. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present utility model with unnecessary details. Therefore, the present utility model is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present utility model.
[0015] Example
[0016] See also Figures 1-2 In an embodiment of the utility model, a key circuit board for a baby stroller steering wheel horn includes a circuit board 1. Buttons 2 are arranged on the left and right sides and the bottom of the surface of the circuit board 1. Arc grooves 3 are opened around the circuit board 1. By arranging a circuit board with an arc groove and a horn button connected in parallel, the key circuit board can be adapted to a steering wheel of a different sex. A wiring port 4 is arranged on the upper end of the back side of the circuit board 1, and the back side of the button 2 is electrically connected to a connecting pin 5.
[0017] The circuit connection relationship between the buttons (2) is a parallel connection.
[0018] When the utility model is used, when the button on the circuit board 1 is pressed, the connection pins 5 at the rear of the button 2 are all connected in parallel, so the pressing signal can be quickly received simultaneously.
[0019] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
