Example III
In this embodiment, the description of the reset structure of the volume adjustment structure is focused, and other contents refer to other embodiments of the present invention.
Fig. 5 is a top view of a volume adjustment structure according to one embodiment of the present invention;
referring to fig. 3 and 5, a return spring limiting piece 7 is arranged at the bottom of the volume knob 1, and the return spring limiting piece 7 penetrates through a hollow circular arc groove frame of the other section of the sliding rail 3;
the inner wall of the shell 2 is provided with a spring positioning piece 9, the spring positioning piece 9 is sleeved with a return spring 8, and two ends of the return spring 8 are respectively connected with two ends of the return spring limiting piece 7.
It can be seen that, in the volume adjusting structure of this embodiment, when the volume knob 1 rotates forward or backward, the reset spring 8 is stretched to rotate, the larger the rotation stroke is, the larger the reset elastic force is, when the user rotates the volume knob 1 to reach the required volume, when the volume knob 1 is loosened, the reset spring 8 can drive the volume knob 1 to return to the initial position, it can cope with the high-strength impact test and the periodic fatigue test, it has no obvious vertical stamping structure, when receiving excessive impact, it is not easy to damage, thereby improving the service life and the safe and reliable use.
Preferably, the return spring limiting piece 7 comprises two return spring 8 limiting posts, and the spring positioning piece 9 comprises two spring positioning posts; the reset spring 8 is arranged into a trapezoid with an opening at the bottom edge, two vertex angles of the trapezoid reset spring 8 are respectively sleeved on the two spring positioning columns, and two side pins of the trapezoid reset spring 8 are respectively clamped on the outer sides of the two reset spring 8 limiting columns. Like this, when user forward or reverse rotation volume knob 1 to increase or reduce the volume, volume knob 1 is opened Guan Xianwei post and is stirred volume toggle switch 6, reset spring 8 is also under the drive of reset spring 8 spacing post, its pin is stirred for reset spring 8 is in holding the power state, when reaching user's demand volume, the user loosens volume knob 1, at this moment, reset spring 8 loses exogenic action, release elastic stress, thereby drive reset spring 8 spacing post, make volume knob 1 reset and reach initial state, thereby make this volume knob 1 can be better fight high strength impact and long-term periodic operation repeatedly, improve life, and the feel comfort level when promoting the user and adjusting the volume.
Preferably, in the initial state of the volume knob 1, the return spring limiting piece 7 is located at the middle position of the hollow circular arc-shaped groove frame of the other section of the sliding rail 3. In this way, the volume knob 1 can have the same stroke when rotating in the forward direction or the reverse direction, so that the volume increase and the volume decrease are adjusted in a more symmetrical and coordinated manner, and the control performance and the effective performance of the volume adjustment are enhanced.
Preferably, in the initial state of the knob, the volume toggle switch limiting piece 5 is located at the middle position of one section of the hollow circular arc-shaped groove frame of the sliding rail 3. Like this, can make volume knob 1 when forward or reverse rotation, its reset spring 8 has the same stroke to make volume knob 1 increase and reduce the return stroke after the volume more symmetrical coordination, optimize reset spring 8 and volume knob 1 the atress condition in the use more, increase life, promote user's use experience.
Preferably, an idle stroke of 3-4 degrees is arranged between the volume toggle switch 6 and the volume toggle switch limiting piece 5. Like this, when can avoid the user to loosen volume knob 1, reset spring 8 drives volume knob 1 and resets the back, arouses volume knob 1 rotatory reciprocating vibration, causes the reciprocal stirring of volume, influences user's use to be favorable to promoting the comfort when user uses, avoid damaging volume knob 1, improve its life and safety in utilization stability.
Example IV
In this embodiment, the description of the buckle 4 of the volume adjusting structure is focused, and other contents refer to other embodiments of the present invention.
The buckle 4 comprises two L-shaped structures with opposite directions, and the two L-shaped structures with opposite directions are respectively clamped on two arc-shaped side edges of the hollow arc-shaped groove frame. Like this, volume knob 1 passes through buckle 4 lock on the slide rail 3 of casing 2, realizes location and gliding structure for volume knob 1 can enough rely on slide rail 3 free rotation, can not be so as to deviate from again in the course of the work, thereby improves convenience and the reliability of volume control regulation.
Preferably, the side wall of the buckle 4 and two ends of the sliding rail 3 limit and position the volume toggle switch 6 so as to protect the volume toggle switch 6 and avoid exceeding the maximum range of the toggle angle, thereby avoiding accidental damage to the volume toggle switch 6 and prolonging the service life and the use safety of the volume knob 1.
It should be noted that, the volume knob of the invention can be welded with a printed circuit board 10 (PCB), the PCB and the housing 2 are assembled together by screws, when the two are installed, the front end of the volume toggle switch 6, namely the toggle wrench of the volume toggle switch 6, is placed between the limit posts of the volume toggle switch 6; the maximum dialing angle of the volume toggle switch 6 is 15-16 degrees, and the effective function dialing angle is 12-14 degrees; meanwhile, the maximum rotation angle of the volume knob 1 is 14 °; in addition, the volume knob 1 may be rotated in a forward or reverse direction according to an internal program of the printed wiring board 10 to increase or decrease the volume; compared with a push-button volume control structure, the volume knob has the advantages that the structure strength is higher, the service life test can be conducted for 30-50 k times, compared with a push-button switch, the volume knob is not obviously vertical to a punching structure, and is not easy to damage when being impacted excessively, so that the service life and the use safety are improved. Preferably, the outer surface of the volume knob 1 is provided with an annular groove, so that friction force when a user rotates the volume knob 1 to adjust volume can be increased, slipping is avoided, and the hand feeling is better.
The foregoing is merely illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
