Technical Field
[0001] This utility model relates to the field of remote control car control handles, and in particular to a rotatable and adjustable structure for a remote control handle. Background Technology
[0002] In the field of remote-controlled car models, the control handle, as the core component for controlling the car's motion, directly impacts the user experience and market acceptance through its structural design and functional adaptability. Currently, the control handles widely used in the industry are mainly divided into two categories: potentiometer handles and slide switch handles. Some products are also experimenting with using game potentiometer handles to improve operational precision.
[0003] All existing control handles share a common problem: fixed operating directions. This means there's a fixed correspondence between the handle's operation and the model car's movement direction. For example, pushing the handle forward corresponds to the model moving forward, and pulling it backward corresponds to the model moving backward. This correspondence cannot be adjusted according to actual usage needs. This deficiency is particularly prominent in model car products with flexible assembly characteristics, such as block cars and modular cars. During assembly, due to structural design or assembly space limitations, the motor gearbox can be installed in either a forward or reverse configuration. However, most remote controls on the market are of a universal design, and their correspondence between operating directions and model car movement directions cannot adapt to the assembly differences of the motor gearbox. In other words, when the motor gearbox is installed in reverse, the remote control command will directly cause a disconnect between the remote control command and the actual movement direction of the model car, resulting in reversed forward and backward movements, and reversed left and right turns.
[0004] The aforementioned orientation compatibility issues not only severely affect the smoothness of operation, making it difficult for users to accurately control the car model, but also prevent children, who are the main user group, from having a smooth controller operation experience. This significantly reduces the playability and practicality of remote control car models, weakens the product's appeal to children, and limits the market development space for flexible assembly remote control car models such as building block cars and assembly cars. Utility Model Content
[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide a structure for a rotatable and adjustable remote control joystick.
[0006] A rotatable and adjustable structure for a remote control handle includes a housing, a mounting cover, a rocker arm, a contact plate, and a circuit board. The circuit board is fixed inside the housing. The housing has a mounting position, and the circuit board has a circular contact surface at the corresponding mounting position. The mounting cover is a cover with openings on both sides. One end of the rocker arm extends from one opening of the mounting cover, and the contact plate is fixed to the other opening of the mounting cover, allowing the other end of the rocker arm to be oscillatingly mounted inside the mounting cover. The rocker arm has a pressing end, and the contact plate has a contact area. The positions of the pressing end and the contact area correspond to the positions of the circular contact surface. The rocker arm and the contact plate are rotatably mounted in the mounting position along with the mounting cover. The center of the circular contact surface coincides with the rotation center of the mounting cover. When the rocker arm oscillates, the pressing end presses against the contact plate, thereby causing the contact area corresponding to the pressing end to contact the circular contact surface.
[0007] According to the rotatable adjustment structure of this application, by making the mounting cover, rocker arm, and contact plate as a whole rotatable, and by aligning the center of the circular contact surface with the rotation center of the mounting cover, the rocker arm can be pressed by the pressing end regardless of how its position is rotated, so that the corresponding contact area and the circular contact surface make contact. That is, no matter how the position of the rocker arm is rotated, the same signal can be input to the circuit board, realizing flexible adaptation of the rocker arm operation direction. Users can adjust the rotation angle of the rocker arm according to their own preferences, solving the problem of fixed operation direction of existing remote control handles.
[0008] Furthermore, a return spring is fitted onto the rocker arm. One end of the return spring is fitted onto the central post of the rocker arm, passing through the contact piece, and the other end is fitted onto the limiting post of the outer casing. This allows the rocker arm to automatically reset after swinging. The return spring eliminates the need for manual return of the rocker arm, conforming to human operating habits and improving ease of use.
[0009] Furthermore, a damping engagement structure is provided between the mounting cover and the mounting position of the outer shell. This damping engagement structure is used for the rotational positioning of the mounting cover. The damping engagement structure effectively realizes the positioning function after the mounting cover rotates, solving the problem of the mounting cover easily sliding after rotation. It ensures that after the user adjusts the operating direction according to needs, the mounting cover can be stably maintained at the target angle and will not shift due to accidental touch or vibration.
[0010] Furthermore, the damping fit structure includes mutually cooperating positioning protrusions and annular positioning grooves, which are respectively disposed on the outer box and the mounting cover. The damping fit structure using positioning protrusions and annular positioning grooves has the advantages of simple structure and low manufacturing difficulty.
[0011] Furthermore, the outer shell extends into the mounting position and is provided with a limiting protrusion ring. The lower end of the limiting protrusion ring is provided with the annular positioning groove. The mounting cover is provided with a limiting groove, and the lower end of the limiting groove is provided with the positioning protrusion. The mounting cover is rotatably mounted on the limiting protrusion ring through the limiting groove, and the positioning protrusion extends into the annular positioning groove to position the rotation angle of the mounting cover.
[0012] Furthermore, the outer casing includes an upper shell and a lower shell that are fixedly connected to each other. The circuit board is fixed in the inner cavity formed by the upper and lower shells, and the mounting position is opened through the top surface of the upper shell. The outer casing adopts a split design with the upper and lower shells snapping together, which greatly facilitates the assembly and subsequent maintenance of core components such as internal circuit boards and rocker arms.
[0013] Furthermore, it also includes a battery and a battery compartment cover. The lower shell has a battery compartment, and the battery compartment cover closes onto the battery compartment to form a cavity for accommodating the battery. The battery is electrically connected to the circuit board. The battery compartment cover and the lower shell form an independent battery cavity, providing a stable and sealed installation space for the battery. It also allows users to quickly remove and replace the battery, ensuring the stability of the remote control's battery life.
[0014] Furthermore, the outer casing is provided with two mounting positions spaced apart, each mounting position is equipped with a set of mounting cover, rocker arm and contact piece, and the circuit board is provided with two concentric circular contact surfaces at the position corresponding to each mounting position.
[0015] Furthermore, the rocker arm has a rotating shaft on the left and right sides, and the mounting cover has a shaft hole for mounting the rotating shaft, so that the rocker arm can swing back and forth around the rotating shaft. The rocker arm has a pressing end on the front and rear sides respectively, so that the pressing end is opposite to the position of the two circular contact surfaces.
[0016] Furthermore, the four circular contact surfaces respectively correspond to the forward and backward functions and the left and right turning functions of the remote control device. Attached Figure Description

[0026] The present invention relates to a rotatable and adjustable structure for a remote control handle, as illustrated in the accompanying drawings.
[0027] like Figures 1 to 9 The diagram illustrates a rotatable and adjustable structure for a remote control handle, comprising a housing 1, a mounting cover 2, a rocker arm 3, a contact piece 4, and a circuit board 5. The circuit board 5 is fixed within the inner cavity of the housing 1. The housing 1 has a mounting position 111. The circuit board 5 has a circular contact surface 51 corresponding to the mounting position 111. The mounting cover 2 is a cover with openings on both sides. One end of the rocker arm 3 extends from one opening of the mounting cover 2. Figure 1 As shown, the rocker arm 3's rocker arm cap 31 has an opening on one side extending out, allowing the user to easily operate the rocker arm 3. A contact piece 4 is fixed to the other side opening of the mounting cover 2. The contact piece 4 can be fixed to the mounting cover 2 by adhesive, riveting, or other fixing methods, allowing the other end of the rocker arm 3 to be oscillatingly mounted inside the mounting cover 2. The rocker arm 3 has a pressing end 34, and the contact piece 4 has a contact area 41. The positions of the pressing end 34 and the contact area 41 correspond to the positions of the circular contact surface 51. The rocker arm 3 and the contact piece 4 are rotatably mounted in the mounting position 111 along with the mounting cover 2. The center of the circular contact surface 51 coincides with the rotation center of the mounting cover 2. When the rocker arm 3 oscillates, the pressing end 34 presses against the contact piece 4, causing the contact area 41 corresponding to the pressing end 34 to contact the circular contact surface 51. Figure 3 and Figure 7As shown, elastic grooves are provided on both sides of the contact area 41, allowing the contact area 41 to tilt upwards normally. When the pressing end 34 is pressed, it presses directly onto the contact area 41, causing the contact area 41 to deform downwards elastically. This allows the contact area 41 to contact the circular contact surface 51, enabling the circuit board 5 to sense the movement of the joystick 3 and control the remote control device to perform the corresponding action. The rotatable adjustment structure of the remote control handle in this application, by making the mounting cover 2, the joystick 3, and the contact piece 4 as a whole rotatable, and by aligning the center of the circular contact surface 51 with the rotation center of the mounting cover 2, ensures that no matter how the position of the joystick 3 is rotated, it can always be pressed by the pressing end 34, causing the corresponding contact area 41 to contact the circular contact surface 51. In other words, no matter how the position of the joystick 3 is rotated, the same signal can be input to the circuit board 5, achieving flexible adaptation of the joystick 3's operating direction. Users can adjust the rotation angle of the joystick 3 according to their own preferences, solving the problem of fixed operating direction in existing remote control handles.
[0028] Figures 1 to 9 As shown, the outer casing 1 includes an upper casing 11 and a lower casing 12 that are fixedly connected to each other. The fixed connection structure between the upper casing 11 and the lower casing 12 can be a snap-fit and / or a threaded connection structure. The threaded connection structure can be a threaded screw post or a screw connection after alignment of threaded holes. The circuit board 5 is fixed in the inner cavity formed by the upper casing 11 and the lower casing 12. Figure 5 and Figure 6 As shown, the lower shell 12 is provided with a threaded fixing post 122 and a positioning post 123. The positioning post 123 is inserted into the positioning hole of the circuit board 5 for positioning. The circuit board 5 is provided with a fixing hole at the corresponding position of the threaded fixing post 122. The circuit board 5 is fixed on the threaded fixing post 122 by screws. The mounting position 111 is opened through the top surface of the upper shell 11.
[0029] like Figure 6 As shown, it also includes a battery 7 and a battery compartment cover 13. The lower shell 12 is provided with a battery compartment, and the battery compartment cover 13 covers the battery compartment to form a cavity for accommodating the battery 7. The battery 7 is electrically connected to the circuit board 5. One end of the battery compartment cover 13 is provided with a plug-in ear and the other end is provided with a fixing hole. The lower shell 12 is provided with a plug-in notch and a screw fixing post at the corresponding position. The plug-in ear is inserted into the plug-in notch, and the other end makes the fixing hole and the screw fixing post aligned, so that the battery compartment cover 13 is covered on the battery compartment by screws.
[0030] like Figure 7 As shown, a return spring 6 is sleeved on the rocker arm 3. One end of the return spring 6 is sleeved on the middle column 33 of the rocker arm 3, and passes through the contact piece 4 in the middle. The other end is sleeved on the limiting column 124 of the outer shell 1, which is used to realize the automatic reset of the rocker arm 3 after swinging.
[0031] like Figures 1 to 4 As shown, a damping fit structure is provided between the mounting cover 2 and the mounting position 111 of the outer shell 1. This damping fit structure is used for the rotational positioning of the mounting cover 2. The damping fit structure includes mutually cooperating positioning protrusions 23 and an annular positioning groove 113, as shown... Figure 4 As shown, multiple positioning grooves in the annular positioning groove 113 are arranged in a circular array, thereby enabling the positioning protrusion 23 to be positioned in each positioning groove. The positioning protrusion 23 and the annular positioning groove 113 are respectively provided on the outer shell 1 and the mounting cover 2. In the embodiment shown in the accompanying drawings of this application, the outer shell 1 extends into the mounting position 111 and is provided with a limiting protrusion ring 112. The lower end of the limiting protrusion ring 112 is provided with the annular positioning groove 113. The mounting cover 2 is provided with a limiting groove 22, and the lower end of the limiting groove 22 is provided with the positioning protrusion 23. The mounting cover 2 is rotatably mounted on the limiting protrusion ring 112 through the limiting groove 22, and the positioning protrusion 23 extends into the annular positioning groove 113 to position the rotation angle of the mounting cover 2.
[0032] like Figures 1 to 9 As shown, in the embodiment of this application, the outer casing 1 is provided with two mounting positions 111 spaced apart. Each mounting position 111 is equipped with a mounting cover 2, a rocker arm 3, and a contact piece 4. The circuit board 5 is provided with two concentric circular contact surfaces 51 at the position corresponding to each mounting position 111.
[0033] The rocker arm 3 has a rotating shaft 32 on the left and right sides. The mounting cover 2 has a shaft hole 21 for mounting the rotating shaft 32, so that the rocker arm 3 can swing back and forth around the rotating shaft 32. At the same time, the rocker arm 3 can rotate synchronously with the mounting cover 2. The rocker arm 3 has a pressing end 34 on the front and rear sides respectively, so that the pressing end 34 is opposite to the two circular contact surfaces 51 respectively.
[0034] The four circular contact surfaces 51 correspond to the forward, backward, left, and right turning functions of the remote control device, respectively. The remote control handle of this application is a toy car remote control handle. The remote control device is a toy car, and can be designed according to human operating habits. One joystick 3 can be set to control the forward and backward functions of the toy car, while the other joystick 3 can be set to control the left and right turning functions. For example, pushing the left joystick 3 forward activates the forward function, and pulling it backward activates the backward function; pulling the right joystick 3 to the left activates the left turning function, and pulling it to the right activates the right turning function. If the motor gearbox of the toy car is reversed in this state, without rotating or adjusting the remote control handle, pushing the left joystick 3 forward activates the backward function, pulling it backward activates the forward function, and pulling the right joystick 3 to the left activates the right turning function. Yes, turning the joystick to the right turns it to the left, which can be difficult for users to adapt to, affecting their operating experience. The remote control handle of this application can rotate the mounting cover 2, joystick 3, and contact piece 4 by 180° through the rotation adjustment structure. At this time, the left joystick 3 can be pushed forward to move forward and pulled back to move backward, and the right joystick 3 can be turned left to turn left and right to turn right. This allows users to always operate the toy car in their preferred way. In addition, it can be rotated and adjusted to other angles according to personal preferences, such as pushing the right joystick 3 up to control the toy car to turn left, or pushing the right joystick 3 at a 45° angle to control the toy car to turn left, thereby enhancing the playability of the toy car.
[0035] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
