Description

Technical Field

[0001] The utility model belongs to the technical field of remote controllers, and in particular relates to a knob-type remote controller. Background Art

[0002] A remote control is a device used to remotely control machinery. Modern remote controls primarily consist of an integrated circuit board and buttons that generate different messages (a message in communication is defined as a set of interrelated, meaningful symbols that can convey a complete meaning).

[0003] With the popularization of smart homes, remote controls are becoming increasingly intelligent and complex, which in turn makes the settings of remote controls more and more complicated, resulting in more and more buttons on remote controls.

[0004] However, there are some problems with the existing technology: in the context of the increasing complexity of intelligence and interactive relationships, current remote controls have more and more control buttons, and the buttons are combined to achieve more interactive settings. For the elderly, the operation is complicated, making the cost of learning and using too high, and it is difficult for the elderly to remember the usage of each button, because the existing buttons are generally used to change channels or adjust the volume through arrow keys in different directions. It is difficult for the elderly to remember the directions clearly, which makes it easy for the elderly to make mistakes when changing channels or adjusting the volume, and the operation process is relatively complicated. Therefore, we propose a knob-type remote control. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a knob-type remote control, which can control the volume and channel switching by setting the knob adjustment mechanism, thereby reducing the possibility of pressing the wrong button and improving the comfort of operation.

[0006] The utility model is implemented as follows: a knob-type remote control comprises a remote control housing, wherein a knob adjustment mechanism is provided in the middle of the remote control housing;

[0007] The knob adjustment mechanism includes a positioning plate fixed to the inside of the remote control housing, a column tube is provided in the middle of the positioning plate, a torsion spring is sleeved on the outside of the column tube, the upper part of the torsion spring is connected to a rotating tube, the middle of the rotating tube is connected to a knob disc via a connecting rod, the bottom end of the connecting rod is movably connected to the inside of the adjustment tube, the adjustment tube is movably located inside the column tube, and the upper end of the rotating tube is fixedly connected to the upper end of the adjustment tube;

[0008] A rotating electrode sheet is fixedly connected to one side of the rotating cylinder, and a positive electrode sheet and a negative electrode sheet are fixedly installed on the positioning plate. The positive electrode sheet and the negative electrode sheet are respectively arranged on both sides of the rotating electrode sheet, and the rotating electrode sheet is in rotational contact with the positive electrode sheet and the negative electrode sheet.

[0009] Specifically, first limiting grooves are obliquely provided on both sides of the column tube, a first limiting rod is fixedly provided at one end of the adjustment tube, and the first limiting rod is rotated and located inside the first limiting groove.

[0010] Specifically, a connecting spring is fixedly installed inside the adjusting cylinder, and the top end of the connecting spring is fixedly connected to the bottom end of the connecting rod.

[0011] Specifically, second limiting rods are fixedly provided on both sides of the connecting rod, a vertical second limiting groove is opened on the inner wall of the adjusting cylinder, and the second limiting rods are movably located inside the second limiting groove.

[0012] Specifically, a limiting ring is fixed on the positioning plate, the limiting ring is located outside the column tube, the torsion spring is located between the limiting ring and the column tube, and both ends of the torsion spring are respectively engaged with the limiting ring and the rotating tube.

[0014] Specifically, the knob disc is movably located on the upper part of the remote control housing, a thumb groove is provided on the upper surface of the knob disc, and a button group is also provided on the upper surface of the remote control housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the utility model is used, the channel switching or volume adjustment control is realized through the knob adjustment mechanism, which can reduce the wrong operation and improve the comfort of operation;

[0017] The knob adjustment mechanism is rotated by the knob disc, and when rotating, it is reset by the torsion spring to facilitate the next knob adjustment. When adjusting the knob, the contact between the rotating electrode piece and the positive electrode piece is triggered to trigger a pulse signal to increase the channel or increase the volume, and the contact between the rotating electrode piece and the negative electrode piece is triggered to trigger a pulse signal to reduce the channel or decrease the volume, thereby realizing the adjustment control of the channel or volume. In order to ensure stable contact, the first limit groove and the first limit rod are set, so that the rotating cylinder can drive the rotating electrode piece to be raised and lowered, thereby making the rotating electrode piece stably contact with the positive electrode piece or the negative electrode piece.

[0041] The specific operation process of this application:

[0042] When using the remote control, when it is necessary to change channels or adjust the volume, the user first selects the channel or volume by pressing the button group 2 on the remote control housing 1, and then performs the control operation through the knob adjustment mechanism 3, that is, the thumb is placed on the thumb groove 318 of the knob disc 305 to rotate the knob disc 305. When the knob disc 305 is rotated, the connecting rod 307 drives the adjustment cylinder 306, and then drives the rotating cylinder 304 to rotate, so that the rotating electrode piece 311 on the rotating cylinder 304 can be rotated. The contact between the rotating electrode piece 311 and the positive electrode piece 312 triggers a pulse signal to achieve channel switching or volume increase, and the contact between the rotating electrode piece 311 and the negative electrode piece 314 triggers a pulse signal to achieve channel switching or volume reduction, thereby achieving channel switching or volume adjustment control. In order to ensure stable contact, the first limiting groove 310 and the first limiting rod 316 are set so that the rotating cylinder 304 can drive the rotating electrode piece 311 to move up and down, thereby ensuring stable contact between the rotating electrode piece 311 and the positive electrode piece 312 or the negative electrode piece 314. The second limiting rod 308 and the second limiting groove 315 are stably connected to the inside of the adjusting cylinder 306 when the rotating cylinder 304 and the adjusting cylinder 306 are adjusted up and down. However, the connecting rod 307 can continuously and stably drive the rotating cylinder 304 and the adjusting cylinder 306 to rotate, and an unloaded electrode sheet 313 is fixedly installed on the positioning plate 301. The unloaded electrode sheet 313 is in contact with the rotating electrode sheet 311, and the unloaded electrode sheet 313 is in contact with the positive electrode sheet 312 and the negative electrode sheet Insulating elastic sheets 319 are respectively connected between 314. The setting of the unloaded electrode sheet 313 is convenient for supporting the rotating electrode sheet 311 and will not trigger a pulse signal. The setting of the insulating elastic sheet 319 is convenient for the rotating electrode sheet 311 to stably move to the positive electrode sheet 312 or the negative electrode sheet 314 when rotating. After rotating to change channels or adjusting the volume, the rotating cylinder 304 is reset by the torsion spring 303, and the rotating electrode sheet 311 moves to the unloaded electrode sheet 313, which is convenient for rotating to change channels or adjusting the volume next time.
