[0056] The present application will be described below with reference to the accompanying drawings. Figure 1 to the accompanying drawings Figure 17 , a record player drive module of the first aspect embodiment of the present application is described.

[0057] With reference to Figures 1 to 4 , the record player drive module of the present embodiment comprises a tone arm drive module and a mounting frame 10, the mounting frame 10 has an inner side facing the interior of the record player and an outer side facing the exterior of the record player, and the tone arm drive module comprises a tone arm assembly 40, a first drive mechanism 50, a lifting frame 60 and a second drive mechanism 70.

[0058] With reference to Figures 1 to 5 , the tone arm assembly 40 comprises a connecting shaft 42 and a tone arm 41, the connecting shaft 42 is provided through the mounting frame 10, the connecting shaft 42 has a first end 421 located at the inner side of the mounting frame 10 and a second end 422 located at the outer side of the mounting frame 10, wherein the first end 421 is provided with a power receiving disc 441; and the tone arm 41 is rotatably connected to the second end 422 of the connecting shaft 42 at one end, and the other end of the tone arm 41 away from the connecting shaft 42 is provided with a stylus 411.

[0059] With reference to Figures 4 to 8 , the first drive mechanism 50 is slidably connected to the inner side of the mounting frame 10 along the axial direction of the connecting shaft 42, and comprises a first drive 520 and a power output disc 540; the first drive 520 is in transmission connection with the power output disc 540 and is used to drive the power output disc 540 to rotate; the power output disc 540 is coaxial with the connecting shaft 42 and opposite to the power receiving disc 441, when the power output disc 540 abuts against the power receiving disc 441, it can transmit power and motion to the power receiving disc 441, thereby driving the entire tone arm assembly 40 to rotate around the axis of the connecting shaft 42, and when driving the tone arm assembly 40 to rotate forward, it can make the tone arm 41 move away from the initial position and turn to the playback end position close to the center of the record, or drive the tone arm assembly 40 to rotate reversely, so that the tone arm 41 moves away from the playback end position close to the center of the record and turns to the initial position.

[0060] With reference to Figure 1 and Figure 5 , the lifting frame 60 is slidably provided through the mounting frame 10 along the axial direction of the connecting shaft 42, and abuts against the side of the tone arm 41 close to the mounting frame 10; with reference to Figure 5 and Figure 6The second driving mechanism 70 comprises a second driver 71, a first output member 72 and a second output member 73, the first output member 72 is connected to the first driving mechanism 50, and the second output member 73 is connected to the lifting frame 60; the second driver 71 is in transmission connection with the first output member 72 and the second output member 73; when the second driver 71 is in forward operation, the first output member 72 can be driven to slide the first driving mechanism 50 so that the power output disc 540 abuts against the power receiving disc 441, and the second output member 73 can be synchronously driven to slide the lifting frame 60 so that the turntable 41 rotates to lift up to the side away from the mounting frame 10; when the second driver 71 is in reverse operation, the first output member 72 can be driven to slide the first driving mechanism 50 so that the power output disc 540 is away from the power receiving disc 441, and the second output member 73 can be synchronously driven to slide the lifting frame 60 so that the turntable 41 rotates to drop down to the side close to the mounting frame 10.

[0061] It should be understood that, since the record player driving module of the embodiment is provided with the first driving mechanism 50 and the second driving mechanism 70, when it is needed to move the turntable 41 from the initial position to the playing start position, the second driver 71 can be first operated in forward direction, so that the first output member 72 is driven to slide the first driving mechanism 50 so that the power output disc 540 abuts against the power receiving disc 441, and the second output member 73 is synchronously driven to slide the lifting frame 60 so that the turntable 41 rotates to lift up to the side away from the mounting frame 10, at this time, the height of the stylus 411 on the turntable 41 will be higher than the upper surface of the record, then the first driver 520 is operated in forward direction to drive the power output disc 540 to rotate in forward direction, so as to drive the power receiving disc 441 and the whole turntable assembly 40 to rotate in forward direction around the axis line of the connecting shaft 42, so that the turntable 41 carrying the stylus 411 moves to the center direction of the record, when the stylus 411 moves above the playing start position at the edge of the record, the second driver 71 is operated in reverse direction, so that the turntable 41 rotates to drop down to the side close to the mounting frame 10, that is, the turntable 41 rotates to drop down, so that the stylus 411 is in contact with the groove on the record, at the same time, the power output disc 540 is away from the power receiving disc 441, that is, the turntable assembly 40 is separated from the first driving mechanism 50, so that the turntable 41 and the stylus 411 can rotate under the driving of the groove on the record to move to the playing end position at the center of the record along with the rotation of the record.

[0062] Similarly, when it is required to move the tone arm 41 from the end of play position to the initial position, the second driver 71 can be first operated in the forward direction to drive the power output disc 540 to slide and abut against the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side away from the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lifting so that the stylus 411 is away from the record, then the first driver 520 is operated in the reverse direction to drive the tone arm 41 to rotate reversely around the axis of the connecting shaft 42 and return to above the initial position, then the second driver 71 is operated in the reverse direction to drive the power output disc 540 to slide and disengage from the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side close to the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lowering so that the tone arm 41 returns to the initial position.

[0063] Similarly, when it is required to move the tone arm 41 from the end of play position to the initial position, the second driver 71 can be first operated in the forward direction to drive the power output disc 540 to slide and abut against the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side away from the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lifting so that the stylus 411 is away from the record, then the first driver 520 is operated in the reverse direction to drive the tone arm 41 to rotate reversely around the axis of the connecting shaft 42 and return to above the initial position, then the second driver 71 is operated in the reverse direction to drive the power output disc 540 to slide and disengage from the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side close to the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lowering so that the tone arm 41 returns to the initial position.

[0064] Similarly, when it is required to move the tone arm 41 from the end of play position to the initial position, the second driver 71 can be first operated in the forward direction to drive the power output disc 540 to slide and abut against the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side away from the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lifting so that the stylus 411 is away from the record, then the first driver 520 is operated in the reverse direction to drive the tone arm 41 to rotate reversely around the axis of the connecting shaft 42 and return to above the initial position, then the second driver 71 is operated in the reverse direction to drive the power output disc 540 to slide and disengage from the power receiving disc 441, and synchronously drive the tone arm 41 to rotate to the side close to the mounting rack 10, i.e. drive the tone arm 41 to complete the rotating lowering so that the tone arm 41 returns to the initial position.

[0065] From the above description, it can be seen that, since the automatic rotation and lifting of the tone arm 41 can be realized by the first driving mechanism 50 and the second driving mechanism 70 respectively, the tone arm 41 can be automatically moved from the initial position to the starting position of the playing on the record by the cooperation of the first driving mechanism 50 and the second driving mechanism 70 at the beginning of the playing, the tone arm 41 can be automatically returned from the ending position of the playing on the record to the initial position after the playing, and the record player can automatically realize the fast-forward playing and the fast-backward playing. Therefore, the automation degree of the record player can be improved and the use experience of the record player can be improved by using the record player driving module of the embodiment.

[0066] It can be understood that, in some embodiments, the record player driving module further comprises a turntable driving module arranged on the mounting frame 10 to ensure the installation position precision between the turntable driving module and the tone arm driving module. The turntable driving mechanism comprises a turntable and a third driving mechanism for driving the turntable to rotate, and the turntable is used for mounting the record and can drive the record to rotate under the driving of the third driving mechanism. It should be understood that, since the turntable driving module is not the improvement point of the present application, the turntable driving module is not shown in the drawings, and the detailed structure of the turntable driving module can refer to the prior art, which will not be described in detail here.

[0067] It can be understood that, in order to better transmit power and motion to the power receiving disc 441, in some embodiments, with reference to Figure 3 , Figure 5 and Figure 8 , the side of the power output disc 540 facing the power receiving disc 441 is provided with a first tooth surface, and the side of the power receiving disc 441 facing the power output disc 540 is provided with a second tooth surface for engaging with the first tooth surface, so that when the power output disc 540 and the power receiving disc 441 abut, the relative sliding between the power output disc 540 and the power receiving disc 441 can be avoided by the engagement between the first tooth surface and the second tooth surface.

[0068] And, with reference to Figure 3 and Figure 8In one embodiment, the first tooth surface is provided with a plurality of first protrusions 542 arranged uniformly and densely, the first protrusions 542 are in the shape of a sharp cone, the second tooth surface is provided with a plurality of second protrusions 443 arranged uniformly and densely, the second protrusions 443 are also in the shape of a sharp cone, and two adjacent first protrusions 542 can be embedded with a second protrusion 443, and two adjacent second protrusions 443 can be embedded with a first protrusion 542, so that the first tooth surface and the second tooth surface can be engaged with each other, and since the first protrusions 542 and the second protrusions 443 are in the shape of a sharp cone, even if the power output disc 540 slides to the power receiving disc 441, the first protrusions 542 can be abutted on the second protrusions 443, and the power receiving disc 441 can be rotated and adjusted by itself under the pushing of the first protrusions 542, so that the first protrusions 542 can be smoothly embedded between two adjacent second protrusions 443 by the self-guiding of the first protrusions 542 and the second protrusions 443. Moreover, by arranging the first protrusions 542 and the second protrusions 443 in a dense and uniform arrangement on the power output disc 540 and the power receiving disc 441 respectively, the diameter of the first protrusions 542 and the second protrusions 443 can be reduced, and the angle of rotation and adjustment of the power receiving disc 441 required when the first protrusions 542 and the second protrusions 443 are engaged can be reduced, so as to improve the minimum fast-forwarding precision of a single fast-forwarding during fast-forwarding.

Figures 5 to 9, the first driving mechanism 50 comprises a housing 510, wherein the first driver 520 and the power output disc 540 are arranged in the housing 510; the housing 510 (the side away from the power receiving disc 441) is opposite to the first output 72, and the side of the housing 510 facing the first output 72 is provided with a first abutting structure 513; the first output 72 is a first lifting gear, and the first lifting gear is provided with a first abutting protrusion 720 on the end face thereof facing the housing 510; the first abutting protrusion 720 is provided with a first abutting inclined surface 721 and a first abutting flat surface 722 for abutting with the first abutting structure 513; the first abutting inclined surface 721 is arranged in a spiral around the axis of the first lifting gear, and the two ends thereof are connected with the end face of the first lifting gear and the first abutting flat surface 722 respectively; and the first abutting flat surface 722 is perpendicular to the axis of the first lifting gear; it should be understood that when the first abutting structure 513 abuts with the end face of the first lifting gear, the first driving mechanism 50 is in a state of being separated from the power receiving disc 441, and when the first abutting structure 513 abuts with the first abutting flat surface 722, the first driving mechanism 50 abuts with the power receiving disc 441 through the power output disc 540; and in the process that the second driver 71 runs forward to drive the first lifting gear to rotate forward, the end face of the first lifting gear, the first abutting inclined surface 721 and the first abutting flat surface 722 can abut with the first abutting structure 513 in turn, so that the first driving mechanism 50 can slide forward, and then the power output disc 540 can abut with the power output disc 540; and in the process that the second driver 71 runs reversely to drive the first lifting gear to rotate reversely, the first abutting flat surface 722, the first abutting inclined surface 721 and the end face of the first lifting gear can abut with the first abutting structure 513 in turn, so that the first driving mechanism 50 can slide reversely, and then the power output disc 540 can be separated from the power output disc 540.

[0070] It can be understood that in some embodiments, with reference to Figure 7 and Figure 8 , the first driving mechanism 50 further comprises a worm 521 and a worm wheel 530; the first driver 520 is a first motor, which is installed in the housing 510; the worm 521 is arranged on the output shaft of the first motor; the worm wheel 530 is also installed in the housing 510 and is coaxially arranged with the connecting shaft 42; the worm 521 is engaged with the worm wheel 530; and the power output disc 540 is arranged on the worm wheel 530; so that when the first driving mechanism 50 slides to the power receiving disc 441 under the driving of the second driving mechanism 70 and the power output disc 540 abuts with the power receiving disc 441, the first motor can drive the worm 521 to rotate, so as to drive the worm wheel 530 and the power output disc 540 to rotate through the worm 521, and then drive the power receiving disc 441 and the tone arm assembly 40 to rotate together.

[0071] It should be understood that the power output disc 540 can be integrally formed with the worm wheel 530, or can be connected to the worm wheel 530 by fasteners.

[0072] It should be understood that, in order to facilitate the installation and fixation of the first motor, the worm wheel 530, the worm 521 and the power output disc 540 on the housing 510, in some embodiments, referring to Figure 7 and Figure 8 , the housing 510 comprises an upper housing 511 and a lower housing 516, and an installation cavity is formed between the upper housing 511 and the lower housing 516, wherein the first motor, the worm wheel 530 and the worm 521 are all accommodated in the installation cavity; wherein the lower housing 516 is provided with a relief 517 corresponding to the position of the power receiving disc 441, and the power output disc 540 passes through the relief 517, so that the first tooth surface can be located outside the housing 510, thereby being able to engage with the second tooth surface; and the first abutting structure 513 is arranged on the upper housing 511 and located on the surface of the upper housing 511 facing the first lifting gear, so that the first abutting structure 513 can abut with the first abutting protrusion 720.

[0073] It should be understood that, in order to realize the sliding of the first driving mechanism 50 on the mounting frame 10, in one embodiment, referring to Figures 5 to 8 , the record player drive module further comprises a connecting frame 20 connected to the inner side of the mounting frame 10, and the first driving mechanism 50 is located between the connecting frame 20 and the mounting frame 10, and the side of the lower housing 516 facing the connecting frame 20 is provided with a plurality of first guide rod portions 518, which are arranged parallel to the axial direction of the connecting shaft 42, and the connecting frame 20 is provided with a plurality of first guide holes 21 corresponding to the first guide rod portions 518, so that the first driving mechanism 50 can slide on the mounting frame 10 along the axial direction of the connecting shaft 42; and in order to keep the first abutting structure 513 and the first lifting gear in abutment at all times, the record player drive module further comprises a plurality of compression springs 30, which are correspondingly sleeved on the first guide rod portions 518, and the two ends of the compression springs 30 are respectively in abutment with the lower housing 516 and the connecting frame 20.

[0074] It can be understood that, in one embodiment, referring to Figures 5 to 8The first lifting gear is coaxially arranged with the connecting shaft 42, and the first lifting gear is arranged on the upper shell 511. The first abutting structure 513 is an arc-shaped convex rib arranged on the side of the upper shell 511 facing the first lifting gear and surrounding the avoiding hole 512. Similarly, the arc-shaped convex rib is provided with a third abutting inclined surface 514 and a fourth abutting flat surface 515 for abutting with the first abutting convex rib 720. The third abutting inclined surface 514 is spirally arranged around the axis of the connecting shaft 42 (i.e. the axis of the first lifting gear), and the two ends are respectively connected to the outer end surface of the upper shell 511 and the fourth abutting flat surface 515. The fourth abutting flat surface 515 is perpendicular to the axis of the connecting shaft 42. The fourth abutting flat surface 515 is used to abut and fit with the end surface of the first lifting gear and the first abutting flat surface 722. The third abutting inclined surface 514 is used to abut and fit with the first abutting inclined surface 721. Therefore, during the cooperation of the first abutting structure 513 and the first abutting convex rib, the surface contact can be maintained all the time, thereby reducing the risk of cooperation failure between the first lifting gear and the first driving mechanism 50 caused by friction.

[0075] It can be understood that, similarly, in order to drive the lifting frame 60 to slide on the mounting frame 10, thereby lifting or lowering the tone arm 41, in one embodiment, referring to Figure 5 、 Figure 6 、 Figure 10 and Figure 11The second abutting structure 61 of the lifting frame 60 is arranged on the side of the lifting frame 60 facing the second output member 73, and the second output member 73 is a second lifting gear. The second lifting gear has a second abutting plane 731, a second abutting inclined surface 732 and a third abutting plane 733 for abutting with the first abutting structure 513. The second abutting inclined surface 732 is arranged helically around the axis of the second lifting gear, and the two ends of the second abutting inclined surface 732 are connected with the second abutting plane 731 and the third abutting plane 733 respectively. The second abutting plane 731 and the third abutting plane 733 are perpendicular to the axis of the second lifting gear. The axis of the second lifting gear is parallel to the axis of the connecting shaft 42. It should be understood that when the second abutting structure 61 abuts with the second abutting plane 731, the lifting frame 60 is in a higher position (i.e. the lifting frame 60 is in a position where the distance from the one end of the mounting frame 10 to the outer side of the mounting frame 10 is larger), and when the second abutting structure 61 abuts with the third abutting plane 733, the lifting frame 60 is in a lower position (i.e. the lifting frame 60 is in a position where the distance from the one end of the mounting frame 10 to the outer side of the mounting frame 10 is smaller). During the forward operation of the second driver 71 to drive the second lifting gear to rotate forward, the third abutting plane 733, the second abutting inclined surface 732 and the second abutting plane 731 can abut with the second abutting structure 61 in turn, so that the lifting frame 60 can slide forward, and the lifting frame 60 can slide to a higher position to lift the turntable 41. During the reverse operation of the second driver 71 to drive the second lifting gear to rotate reversely, the second abutting plane 731, the second abutting inclined surface 732 and the third abutting plane 733 can abut with the second abutting structure 61 in turn, so that the lifting frame 60 can slide reversely, and the lifting frame 60 can slide to a lower position, so that the turntable 41 can descend with the lifting frame 60 (during the descending process, the turntable 41 can abut with the lifting frame 60 under the action of gravity or elastic force).

[0076] It should be understood that, in order to realize the sliding of the lifting frame 60 on the mounting frame 10, in one embodiment, with reference to Figure 10The lifting frame 60 comprises an arc-shaped support table 62, a lifting seat 63, and a second guide rod part 64 and a second abutting structure 61 arranged on the side of the lifting seat 63 away from the arc-shaped support table 62. The arc-shaped support table 62 and the lifting seat 63 are located on the outer side of the mounting frame 10, and the arc-shaped support table 62 is used for abutting the tone arm 41. The second abutting structure 61 is a top rod part, and the top rod part and the second guide rod part 64 are parallel to the axis of the connecting shaft 42. The mounting frame 10 is provided with a second guide hole (not shown in the figure) and a third guide hole 11 matched with the second guide rod part 64 and the top rod part respectively, so that the lifting frame 60 can slide on the mounting frame 10 along the axis of the connecting shaft 42. The end of the top rod part away from the lifting seat 63 is used for abutting the second lifting gear, so that the second lifting gear cooperates with the top rod part to drive the lifting frame 60 and the tone arm 41 to lift together.

[0077] It can be understood that, in order to transmit the power and movement of the first driver 520 to the first lifting gear and the second lifting gear respectively, in some embodiments, referring to Figure 6 The second driving mechanism 70 comprises a transmission gear set 74, and the second driver 71 is a second motor. The second motor is in transmission connection with the first lifting gear through the transmission gear set 74. It should be understood that the transmission gear set 74 at least comprises a pair of meshing gears, and the input gear in the transmission gear set 74 is arranged on the output shaft of the second motor, and the output gear in the transmission gear set 74 is in meshing with the first lifting gear. Therefore, the rotation and torque of the second motor can be transmitted to the first lifting gear through the transmission gear set 74, so as to drive the first transmission gear to rotate, thereby driving the first driving mechanism 50 to slide. In addition, the first lifting gear is in meshing with the second lifting gear, so that the power can also be transmitted to the second lifting gear through the first lifting gear, thereby driving the second transmission gear to rotate, and further driving the lifting frame 60 to slide and lift. It should be understood that, by arranging the second lifting gear in meshing with the first lifting gear, it is also convenient to calculate and design the relationship between the central angle corresponding to the first abutting inclined surface 721 and the central angle corresponding to the second abutting inclined surface 732 through the transmission ratio between the second lifting gear and the first lifting gear, so as to ensure that when the power output disc 540 abuts against the power receiving disc 441, the tone arm 41 has also been lifted into place, thereby avoiding scratching the record by the stylus 411 when the first driving mechanism 50 subsequently drives the tone arm 41 to rotate.

[0078] It can be understood that, referring to Figure 6, in order to facilitate the control of the first driving mechanism 50 and the second driving mechanism 70 to cooperate, in some embodiments, the record player driving module further comprises a control module (not shown in the figure) and a lifting to position detection device 81, wherein the control module is electrically connected with the lifting to position detection device 81, the first driver 520 and the second driver 71, the first driving mechanism 50 is provided with an abutting portion 519, the lifting to position detection device 81 is opposite to the abutting portion 519, and when the power output disc 540 abuts against the power receiving disc 441, the abutting portion 519 enters the detection range of the lifting to position detection device 81, and the control module can control the second driver 71 according to the detection signal of the lifting to position detection device 81. It should be understood that, through the above structure, when the tone arm 41 needs to be lifted, the control module will control the second driver 71 to operate forward to drive the first driving mechanism 50 to slide towards the power receiving disc 441, and synchronously control the lifting frame 60 to slide to a higher position, and when the lifting to position detection device 81 detects the abutting portion 519, it means that the power output disc 540 abuts against the power receiving disc 441, and the lifting frame 60 drives the tone arm 41 to rotate to the lifting position, and the lifting to position detection device 81 can send a corresponding detection signal to the control module, and the control module will control the second driver 71 to stop running according to the detection signal generated by the lifting to position detection device 81 at this time, and control the first driver 520 to start running; when the tone arm 41 needs to be lowered, the control module will control the second driver 71 to operate reversely to drive the first driving mechanism 50 to slide away from the power receiving disc 441, and synchronously control the lifting frame 60 to slide to a lower position, and when the lifting to position detection device 81 detects that the abutting portion 519 is out of its detection range, it can send a corresponding detection signal to the control module, and the control module will control the second driver 71 to stop running after a preset time delay according to the detection signal generated by the lifting to position detection device 81 at this time, so that the tone arm 41 can be lowered from the lifting position by a sufficient distance, and then the tone arm 41 can abut against the record or be lowered back to the initial position.

[0079] It can be understood that, in one embodiment, referring to Figures 6 to 8 , specifically, the lifting to position detection device 81 is a detection switch, and the abutting portion 519 is arranged on the upper shell 511 and opposite to the detection switch, so that when the abutting portion 519 enters the detection range of the detection switch, the abutting portion 519 abuts against the detection switch to make the detection switch conduct, and when the abutting portion 519 is out of the detection range of the detection switch, the abutting portion 519 is separated from the detection switch to make the detection switch break.

[0080] It should be understood that in some other embodiments, the abutting portion 519 can also be selectively arranged on the lifting frame 60, for example, the abutting portion 519 can be arranged on the second guide rod portion 64, and the detection switch can be arranged on the mounting frame 10 and located between the abutting portion 519 and the mounting frame 10, so that when the lifting frame 60 slides to a higher position, the abutting portion 519 can abut against the detection switch to turn on the detection switch, and when the lifting frame 60 slides to a lower position, the abutting portion 519 is separated from the detection switch and can turn off the detection switch.

[0081] It can be understood that in some embodiments, the first sensing portion 451 is arranged on the connecting shaft 42, and the connecting shaft 42 is arranged on the arm drive module 40. Figure 12 The arm drive module further comprises an initial position sensor 82 and an end position sensor 83, which are arranged at intervals along the circumference of the connecting shaft 42. The connecting shaft 42 is provided with a first sensing portion 451, and the connecting shaft 42 can drive the first sensing portion 451 to rotate into the sensing area of the initial position sensor 82 and the end position sensor 83. The control module is electrically connected with the initial position sensor 82 and the end position sensor 83, and can control the first driver 520 and the second driver 71 according to the sensing signals of the initial position sensor 82 and the end position sensor 83.

[0082] It should be understood that when the first sensing portion 451 rotates reversely with the connecting shaft 42 to the sensing area of the initial position sensor 82, the tone arm 41 also reversely rotates to above the initial position, at which time the control module can control the first driver 520 to stop running according to the sensing signal of the initial position sensor 82, and then control the second driver 71 to reversely run, so that the tone arm 41 descends to the initial position. When the first sensing portion 451 rotates with the connecting shaft 42 to the sensing area of the end position sensor 83, the tone arm 41 also correspondingly rotates to the playing end position of the record, at which time the control module can control the first driver 520 to stop running according to the sensing signal of the end position sensor 83, and then control the second driver 71 to positively run, so that the tone arm 41 is lifted to separate from the record, and then control the first driver 520 and the second driver 71 to cooperate to make the tone arm 41 return to the initial position.

[0083] It can be understood that in some embodiments, common records usually have two specifications of 17" and 30", and the playing start positions of the edges of the records of the two specifications are different. In order to make the tone arm 41 automatically reach the playing start positions of the records of the two different specifications, the first sensing portion 451 is arranged on the connecting shaft 42. Figure 12The arm drive module further comprises a first edge position sensor 84 and a second edge position sensor 85, which are also arranged along the circumference of the connecting shaft 42, and the connecting shaft 42 is provided with a second sensing portion 452, and the connecting shaft 42 can drive the second sensing portion 452 to rotate into the sensing area of the first edge position sensor 84 and the second edge position sensor 84; the control module is electrically connected with the first edge position sensor 84 and the second edge position sensor 84, and can control the first driver 520 and the second driver 71 according to the sensing signals of the first edge position sensor 84 and the second edge position sensor 84.

[0084] It should be understood that, as the record is a 30" record, during the process of starting playing and the arm 41 turning to the record, when the second sensing portion 452 rotates forward with the connecting shaft 42 to the sensing area of the first edge position sensor 84, the arm 41 also rotates forward to above the playing start position of the edge of the 30" record, at this time the control module will be able to control the first driver 520 to stop running according to the sensing signal of the first edge position sensor 84, and then control the second driver 71 to run reversely, so that the arm 41 descends and the stylus 411 abuts against the playing start position of the edge of the 30" record.

[0085] Similarly, as the record is a 17" record, during the process of starting playing and the arm 41 turning to the record, when the second sensing portion 452 rotates forward with the connecting shaft 42 to the sensing area of the second edge position sensor 85, the arm 41 also rotates forward to above the playing start position of the edge of the 17" record, at this time the control module will be able to control the first driver 520 to stop running according to the sensing signal of the second edge position sensor 85, and then control the second driver 71 to run reversely, so that the arm 41 descends and the stylus 411 abuts against the playing start position of the edge of the 17" record.

[0086] It can be understood that, in one embodiment, referring to Figure 12 The initial position sensor 82, the end position sensor 83, the first edge position sensor 84 and the second edge position sensor 85 all select to use photoelectric sensors, which comprise spaced apart emitting portions and receiving portions, and the sensing area of the photoelectric sensor is located between the emitting portion and the receiving portion, so that when the first sensing portion 451 or the second sensing portion 452 rotates into between the corresponding emitting portion and receiving portion of the photoelectric sensor, a corresponding sensing signal will be generated.

[0087] It should be understood that, in some other embodiments, the initial position sensor 82, the end position sensor 83, the first edge position sensor 84 and the second edge position sensor 85 can also select to use detection switches.

[0088] It can be understood that, in some embodiments, with reference to Figure 6 and Figure 12 , the record player drive module further comprises a circuit board 80, which is fixedly installed between the mounting frame 10 and the connecting frame 20; and the control module, the lifting-in-place detection device 81, the initial position sensor 82, the end position sensor 83, the first edge position sensor 84 and the second edge position sensor 85 are all integrally arranged on the mounting frame 10, so as to facilitate assembly.

[0089] It can be understood that, in order to facilitate the connection shaft 42 to pass through the first drive mechanism 50, the mounting frame 10 and the connecting frame 20, and to facilitate the first sensing part 451 and the second sensing part 452 to be arranged on the connection shaft 42, in some embodiments, with reference to Figure 3 , Figure 5 , and Figures 13 to 18 , the connection shaft 42 comprises a shaft body 430, a power receiving piece 440, a detection piece 450 and a threaded locking piece 490, wherein the power receiving disc 441 is arranged on the power receiving piece 440, the first sensing part 451 and the second sensing part 452 are correspondingly arranged on the detection piece 450, and the shaft body 430 passes through the mounting frame 10, the first drive mechanism 50 and the connecting frame 20, and one end of the shaft body 430 located outside the mounting frame 10 is the second end 422 of the connection shaft 42, and the power receiving piece 440, the detection piece 450 and the threaded locking piece 490 are detachably connected to one end of the shaft body 430 located inside the mounting frame 10, and together with one end of the shaft body 430 located inside the mounting frame 10 form the first end 421 of the connection shaft 42; wherein the shaft body 430 is provided with a threaded part 431, a square shaft part 432 and a limiting part 433, the threaded part 431 is arranged at one end of the shaft body 430 away from the tone arm 41, the square shaft part 432 is adjacent to the threaded part 431, and the limiting part 433 protrudes circumferentially from the shaft body 430 and is located on the side of the square shaft part 432 away from the threaded part 431; the center of the power receiving piece 440 is provided with a square hole 444, the shaft body 430 passes through the square hole 444 and cooperates with the square hole 444 through the square shaft part 432, so as to receive the rotating power transmitted by the power receiving piece 440; the shaft body 430 abuts against the power receiving piece 440 through the limiting part 433, so as to limit the power receiving piece 440 from sliding on the shaft body 430 towards the side close to the first drive mechanism 50; the detection piece 450 is sleeved on the shaft body 430 and located on the side of the power receiving piece 440 away from the first drive mechanism 50, and the threaded locking piece 490 is used for threaded connection with the threaded part 431, so as to cooperate with the limiting part 433 to press and fix the power receiving piece 440 and the detection piece 450 on the shaft body 430.

[0090] It should be understood that in some embodiments, the detection element 450 is rotatably and adjustably connected to the power receiver 440, so that when the threaded locking member 490 is loosened, the angle between the detection element 450 and the tonearm 41 can be adjusted so that when the first sensing part 451 or the second sensing part 452 on the detection element 450 enters the sensing range of the corresponding sensor, the tonearm 41 can be in the corresponding position. For example, when the first sensing part 451 enters the sensing range of the initial position sensor 82, the tonearm 41 can be just in the initial position, or the tonearm 41 can be just above the initial position.

[0091] It should be understood that, in order to achieve rotatable adjustment of the detection element 450 on the power receiving element 440, in one embodiment, reference is made to... Figure 5 , Figures 13 to 18 The power receiver 440 has an annular groove 445 on the side facing away from the first drive mechanism 50, and the detection member 450 has an annular platform portion 453 embedded in the annular groove 445, thereby being rotatably connected to the power receiver 440 by means of the engagement of the annular platform portion 453 and the annular groove 445. Furthermore, the detection member 450 has an abutment block 454 on the side facing away from the first drive mechanism 50, and the power receiver 440 has an adjusting screw 470 on the side facing the detection member 450. The adjusting screw 470 is adjacent to the abutment block 454 and has a circular abutment piece 471 for engaging with the abutment block 454. The abutment block 454 has an adjusting ramp 455 on the side facing the circular abutment piece 471. The distance from the adjusting ramp 455 to the central axis of the adjusting screw 470 gradually increases in the direction away from the power receiver 440. The detection member 450 and the power receiver 440... The tension spring 480 provides elastic force to keep the abutment block 454 abutting the circular abutment piece 471. With the above structure, when the threaded locking member 490 is loosened, the relative angle between the detection member 450 and the power receiver 440 can be adjusted by rotating the adjusting screw 470 to screw the adjusting screw 470 in or out of the power receiver 440, that is, the relative angle between the detection member 450 and the tonearm 41 can be adjusted. Then, the threaded locking member 490 is tightened to keep the detection member 450 and the tonearm 41 at the adjusted angle.

[0092] It should be understood that, for ease of connection of the tension spring 480, in one embodiment, reference is made to...

[0094] The record player of the second aspect of the present application is described below, and the record player of the present embodiment comprises the record player driving module of the first aspect of the present application. It should be understood that by adopting the record player driving module of the first aspect of the present application, the tone arm 41 can be automatically moved from the initial position to the play start position and from the play end position to the initial position, and the record player can also realize automatic fast forward play and automatic fast reverse play, so that the record player of the present embodiment has a high degree of automation and can effectively improve the user experience.

[0095] The control method of the record player of some embodiments of the third aspect of the present application is described below. It should be understood that in some embodiments, the record player further comprises a plurality of keys such as a start key, a stop key, a fast forward key, a fast reverse key, etc., and the start key, the stop key, the fast forward key, the fast reverse key, etc. are electrically connected with the control module. Correspondingly, the control method of the record player comprises a plurality of control processes such as a play control process, a stop play control process, a fast forward control process, a fast reverse control process, etc., and the corresponding control process can be started by pressing the corresponding key.

[0096] For example, in some embodiments, the play control process comprises, but is not limited to, the following steps S110 to S180.

[0097] S110, when the control module detects that the start key is pressed, the control module controls the second driver 71 to run in the forward direction.

[0098] It should be understood that in step S110, the forward running of the second driver 71 drives the first driving mechanism 50 to slide towards the power receiving disc 441, and simultaneously drives the lifting frame 60 to slide to gradually lift the tone arm 41 in the initial position.

[0099] S120, when the abutting portion 519 enters the detection range of the lifting to position detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifting to position detection device 81, and controls the first driver 520 to run in the forward direction to drive the tone arm 41 to rotate towards the center of the record.

[0100] It should be understood that, in step S320, when the abutting portion 519 enters the detection range of the lifting-in-position detection device 81, it indicates that the tone arm 41 has completed lifting and the power output disc 540 has abutted against the power receiving disc 441, at which time the control module controls the second driver 71 to stop running and controls the first driver 520 to run forward, i.e., to drive the power output disc 540 and the entire tone arm assembly 40 to rotate forward, thereby causing the tone arm 41 to rotate from the initial position to the center of the record.

[0101] S130, when the second sensing portion 452 enters the sensing area of the first edge position sensor 84 or the second edge position sensor 85, the control module controls the first driver 520 to stop running and controls the second driver 71 to run in reverse according to the sensing signal generated by the first edge position sensor 84 or the second edge position sensor 85.

[0102] It should be understood that, with respect to the above step S130, when the second sensing portion 452 enters the sensing area of the first edge position sensor 84 or the second edge position sensor 85, it indicates that the tone arm 41 has carried the stylus 411 to above the play start position, at which time the control module controls the first driver 520 to stop running and controls the second driver 71 to run in reverse, i.e., to cause the tone arm 41 to gradually lower the stylus 411.

[0103] S140, when the abutting portion 519 exits the detection range of the lifting-in-position detection device 81, the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifting-in-position detection device 81.

[0104] It should be understood that, with respect to the above step S140, when the abutting portion 519 exits the detection range of the lifting-in-position detection device 81, it indicates that the first driving mechanism 50 has begun to disengage from the power receiving disc 441, and at the same time, the lifting frame 60 is synchronously driving the tone arm 41 to descend, and the control module controls the second driver 71 to stop running after a preset time, which can cause the lifting frame 60 to drive the tone arm 41 to descend by a sufficient distance and enable the stylus 411 on the tone arm 41 to abut against the play start position on the record.

[0105] S150, when the first sensing portion 451 enters the sensing area of the end position sensor 83, the control module controls the second driver 71 to run forward according to the sensing signal generated by the end position sensor 83.

[0106] It should be understood that, as to the step S150 described above, as the record is played and rotated (achieved by controlling the operation of the turntable driving module), the stylus 411 and the tone arm 41 will also be moved to the play end position at the center of the record under the drive of the groove of the record, and the first sensing part 451 also enters the sensing area of the end position sensor 83 at this time, at which time the second driver 71 is controlled to operate forward, so that the tone arm 41 is lifted and the stylus 411 is separated from the record.

[0107] S160, when the abutting part 519 enters the detection range of the lifting in place detection device 81, the control module controls the second driver 71 to stop operating according to the detection signal generated by the lifting in place detection device 81, and controls the first driver 520 to operate reversely to drive the tone arm 41 to turn to the initial position.

[0108] S170, when the first sensing part 451 enters the sensing area of the initial position sensor 82, the control module controls the first driver 520 to stop operating according to the sensing signal generated by the initial position sensor 82, and controls the second driver 71 to operate reversely.

[0109] It should be understood that, as to the step S170 described above, when the first sensing part 451 enters the sensing area of the initial position sensor 82, it indicates that the tone arm 41 has been turned above the initial position, at which time the control of the first driver 520 to stop operating and the control of the second driver 71 to operate reversely can make the tone arm 41 start to descend.

[0110] S180, when the abutting part 519 exits the detection range of the lifting in place detection device 81, the control module controls the second driver 71 to stop operating after a preset time according to the detection signal generated by the lifting in place detection device 81.

[0111] It should be understood that, as to the step S180 described above, when the abutting part 519 exits the detection range of the lifting in place detection device 81, it indicates that the first driving mechanism 50 has started to separate from the power receiving disc 441, at the same time, the lifting frame 60 also synchronously drives the tone arm 41 to descend, and the control of the second driver 71 to stop operating after a preset time can make the lifting frame 60 drive the tone arm 41 to descend by a sufficient distance and make the tone arm 41 be able to descend back to the initial position.

[0112] It should be understood that, through the play control process of the embodiment, the record player can automatically play when the play key is pressed and automatically reset the tone arm 41 to the initial position after the play is completed, so as to avoid damaging the record and the stylus 411, thereby not only improving the user experience, but also reducing the damage risk to the record and the stylus 411.

[0116] S220, when the abutting portion 519 enters the detection range of the lifting-to-position detection device 81, the control module controls the second driver 71 to stop running according to the detection signal generated by the lifting-to-position detection device 81, and controls the first driver 520 to run reversely to drive the tone arm 41 to turn to the initial position.

[0117] S230, when the first sensing portion 451 enters the sensing area of the initial position sensor 82, the control module controls the first driver 520 to stop running according to the sensing signal generated by the initial position sensor 82, and controls the second driver 71 to run reversely.

[0125] S340, when the abutting portion 519 is out of the detection range of the lifting-in-place detection device 81, the control module controls the second driver 71 to stop running after a preset time according to the detection signal generated by the lifting-in-place detection device 81.

[0126] It should be understood that, as to the above step S340, when the abutting portion 519 is out of the detection range of the lifting-in-place detection device 81, it indicates that the first driving mechanism 50 has started to be out of the power receiving disc 441, at the same time, the lifting frame 60 also synchronously drives the tone arm 41 to descend, and the control module controls the second driver 71 to stop running after a preset time, so that the tone arm 41 can descend a sufficient distance to ensure that the stylus 411 on the tone arm 41 can abut against the record.
