Best mode of the present application

[0054] In view of the fact that the hardness and smoothness of the ball bearing are required to be high in the current rotation support form of the shaft core through the ball bearing, the material cost and machining precision are required to be high, and the ball bearing is prone to be damaged by friction for a long time, so that the ball bearing is no longer smooth or the spherical structure is deformed, which is not conducive to improving the stability during use. The embodiments of the present application provide the following technical solutions to overcome the above problems. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0055] As shown in FIG. 1 to FIG. 5, the embodiment of the present application provides a black record device 100, comprising: a body 110, a rotating shaft 120, a rotating disc 130, a driving assembly 140 connected with the body 110, the rotating shaft 120 is rotatably connected with the body 110 through a bearing assembly 150, the rotating shaft 120 is fixedly connected with the rotating disc 130, and the rotating disc 130 has a preset distance with the body 110, the driving assembly 140 is arranged on the body 110, and the driving assembly 140 is drivingly connected with the rotating disc 130, the rotating shaft 120 comprises a first connecting section 122 and a second connecting section 124 connected in sequence, the first connecting section 122 is connected with the bearing assembly 150, and the second connecting section 124 is connected with the rotating disc 130; wherein the diameter of the first connecting section 122 is smaller than the diameter of the second connecting section 124, so that the end of the second connecting section 124 towards the first connecting section 122 is clamped and limited by the bearing assembly 150, or the connecting part of the first connecting section 122 and the second connecting section 124 is provided with an annular clamping convex 126, so that the rotating shaft 120 is clamped and limited by the bearing assembly 150 through the annular clamping convex 126.

[0056] Specifically, in order to ensure the stability of rotation between the rotating shaft 120 and the body 110, the bearing assembly 150 is connected between the rotating shaft 120 and the body 110, at the same time, the rotating shaft 120 is connected with the bearing assembly 150 through the first connecting section 122 and connected with the rotating disc 130 through the second connecting section 124, so as to ensure the preset distance between the rotating disc 130 and the body 110, thereby ensuring that the rotating disc 130 is not affected by the body 110 when rotating. When the rotating shaft 120 supports the rotating disc 130 and rotates with the rotating disc 130, in order to ensure the reliability of the rotating disc 130 when rotating, the annular clamping convex 126 (as shown in FIG. 4) is arranged at the connecting part of the first connecting section 122 and the second connecting section 124, at this time, the annular clamping convex 126 can be clamped with the bearing assembly 150 to limit the rotating shaft 120, thereby avoiding the axial movement of the rotating shaft 120, so as to ensure the stability of the rotating disc 130 when rotating, and make the rotating disc 130 and the needle better cooperate. It can be understood that the diameter of the first connecting section 122 can also be smaller than the diameter of the second connecting section 124, in this way, the end of the second connecting section 124 towards the first connecting section 122 can be clamped and limited by the bearing assembly 150, so as to achieve the same purpose. In order to ensure the stable fit between the bearing assembly 150 and the end of the first connecting section 122, and avoid the influence of machining precision, a ring groove 127 can be arranged at one end of the first connecting section 122 towards the second connecting section 124. By using the above-mentioned manner, when the second connecting section 124 cooperates with the bearing assembly 150, the ring groove 127 is arranged to modify the end surface cooperation of the second connecting section 124, so as to ensure better cooperation, which is beneficial to improve the stability during use.

[0057] The record player device 100 provided by the embodiment of the present application is characterized in that: the bearing assembly 150 is arranged on the machine body 110, and the rotating shaft 120 is rotatably connected with the machine body 110 through the bearing assembly 150; when the rotating disc 130 is driven to rotate by the driving assembly 140, the rotating disc 130 drives the rotating shaft 120 to rotate relative to the machine body 110, so as to ensure the stability of the rotating shaft 120. Meanwhile, the annular clamping protrusion 126 is arranged at the connection position of the first connecting section 122 and the second connecting section 124 of the rotating shaft 120, or the diameter of the first connecting section 122 is smaller than the diameter of the second connecting section 124; when the rotating shaft 120 is matched with the bearing assembly 150, the rotating shaft 120 is limited by the second connecting section 124 or the annular clamping protrusion 126, so that the rotating disc 130 connected with the rotating shaft 120 is kept at a stable distance from the machine body 110, and the rotating disc 130 does not fluctuate up and down when rotating, so that the cooperation between the tone arm and the rotating disc 130 is kept stable. In the above manner, the required support is achieved without using balls, the requirement for the machining precision is relatively low, the material cost and the machining cost are reduced, and the stability during use is improved.

[0058] As shown in FIGS. 5, 6 and 7, the bearing assembly 150 comprises a bearing seat 152 connected with the machine body 110, and a first bearing 154 and a second bearing 156 arranged in the bearing seat 152 in a spaced manner, wherein the outer rings of the first bearing 154 and the second bearing 156 are connected with the bearing seat 152 respectively, the inner rings of the first bearing 154 and the second bearing 156 are connected with the first connecting section 122 respectively, and the annular clamping protrusion 126 or the second connecting section 124 abuts against the inner ring of the first bearing 154.

[0059] Specifically, the first bearing 154 and the second bearing 156 are arranged in the bearing seat 152 in a spaced manner, so that the rotating shaft 120 is supported in a distributed manner, the probability of bending of the rotating shaft 120 due to stress concentration is reduced, and the coaxiality of the rotating shaft 120 during rotation is facilitated to be ensured. In addition, the annular clamping protrusion 126 or the second connecting section 124 abuts against the inner ring of the first bearing 154, so that the first bearing 154 limits the rotating shaft 120, thereby ensuring the stability of the rotating shaft 120 at the current position.

[0060] As shown in FIGS. 5 and 7, the bearing seat 152 comprises a seat body 1522 and a through hole 1524 arranged in the seat body 1522; the first bearing 154 and the second bearing 156 are arranged at two ends of the through hole 1524 respectively, and a spacer is arranged between the first bearing 154 and the second bearing 156, or two accommodating grooves are arranged at two ends of the through hole 1524 respectively, the accommodating grooves are arranged concentrically with the through hole 1524, and the first bearing 154 and the second bearing 156 are clamped in the accommodating grooves respectively.

[0061] Specifically, when the first bearing 154 and the second bearing 156 are limited by the spacer, the relative position stability of the first bearing 154 and the second bearing 156 can be ensured, so that when the axial movement of the rotating shaft 120 is limited by the first bearing 154, the position dislocation of the first bearing 154 can be avoided to affect the limitation of the rotating shaft 120, and the stability during use can be ensured. It can be understood that by arranging the accommodating grooves at both ends of the through hole 1524, when the first bearing 154 and the second bearing 156 are connected with the bearing seat 152, they can be clamped in the accommodating grooves respectively, so as to limit the first bearing 154 and the second bearing 156 through the accommodating grooves, and ensure the stability of the relative position relationship of the first bearing 154 and the second bearing 156 with the bearing seat 152. At this time, when the axial movement of the rotating shaft 120 is limited by the first bearing 154, the position dislocation of the first bearing 154 can also be avoided to affect the limitation of the rotating shaft 120, and the stability during use can be ensured.

[0062] As shown in FIGS. 2, 4 and 7, the second connecting section 124 is provided with a limiting groove 128, and a rotating disc 130 is arranged at the limiting groove 128 and integrally injection molded with the second connecting section 124; the rotating disc 130 comprises an inner disc 132 and an outer disc 134 arranged on the second connecting section 124, and the inner disc 132 is provided with a connecting part 136, and the rotating disc 130 is connected with the second connecting section 124 through the connecting part 136.

[0063] Specifically, by arranging the limiting groove 128 on the second connecting section 124, when the rotating disc 130 is integrally injection molded with the second connecting section 124, the limiting clamping convex 1362 can be formed at the corresponding position of the rotating disc 130 and the limiting groove 128, and better cooperate with the rotating shaft 120, so as to prevent the loosening phenomenon at the connection between the rotating disc 130 and the rotating shaft 120. In addition, the connecting part 136 is located at the center of the disc body 172, and plays a role in strengthening the connection strength at the connection between the inner disc 132 and the rotating shaft 120. The limiting clamping convex 1362 is formed in the inner ring of the connecting part 136, so as to cooperate with the rotating shaft 120 more stably.

[0064] As shown in FIGS. 2 and 6, the driving assembly 140 comprises a motor 142 arranged on the machine body 110, and a transmission wheel 144 connected with the motor 142, and the transmission wheel 144 is located between the inner disc 132 and the outer disc 134 and is in transmission connection with the inner disc 132.

[0065] Specifically, the transmission wheel 144 and the inner disc 132 can be connected through a conveyor belt to reduce the vibration and noise generated during transmission and ensure the stability of rotation. At the same time, the outer disc 134 can not only bear the turntable, but also shield and protect the inner disc 132 and the transmission wheel 144, which is conducive to improving the stability during use.

[0066] Please continue to refer to FIG. 2 and FIG. 6, the outer ring of the outer disc 134 is provided with a flange 1342 which is folded towards the side of the body 110; the inner disc 132 is provided with a plurality of reinforcing ribs 138 on the side of the body 110, the reinforcing ribs 138 are connected between the inner disc 132 and the connecting portion 136.

[0067] In the above form, the gap between the outer ring of the rotating disc 130 and the body 110 can be smaller, avoiding other sundries from mixing between the body 110 and the rotating disc 130, which is beneficial to ensure the stability during use. At the same time, by providing the flange 1342 on the outer ring of the outer disc 134, the structural strength of the outer disc 134 can be improved, avoiding the outer disc 134 from being torn from the edge under stress. In addition, the reinforcing ribs 138 are connected between the inner disc 132 and the connecting portion 136, not only improving the connection strength between the inner disc 132 and the rotating shaft 120 through the connecting portion 136, but also enhancing the overall structural strength of the rotating disc 130, avoiding accidental breakage and damage of the rotating disc 130, so as to ensure the reliability during use.

[0068] In an optional embodiment of the present application, as shown in FIG. 8, the vinyl record device 100 further comprises a cabinet 160, the cabinet 160 comprises a shell, a control unit and a sound generating unit arranged in the shell, the sound generating unit and the driving assembly 140 are electrically connected with the control unit, the shell is connected with the body 110 on the side away from the rotating disc 130, and the cabinet 160 and the body 110 are respectively provided with shock-absorbing foot pads 162.

[0069] Specifically, the control unit can control the operation of the driving assembly 140 to ensure the stable operation of the turntable, thereby ensuring the use effect of the sound generating unit and improving the sound quality during use. At the same time, by arranging the shock-absorbing foot pads 162 on the cabinet 160 and the body 110 respectively, it is beneficial to reduce the vibration problem generated when the sound generating unit generates sound, which is beneficial to ensure the sound quality of the sound generating unit.

[0070] As shown in FIG. 4, FIG. 8 and FIG. 9, the first connecting section 122 is provided with a code disc 170, the code disc 170 and the cabinet 160 are located on the side of the body 110 away from the rotating disc 130, and the body 110 is further provided with a speed sensor 176 corresponding to the code disc 170, the speed sensor 176 is electrically connected with the control unit.

[0071] Specifically, the rotation of the rotating disc 130 is driven by the driving assembly 140, when the rotating disc 130 rotates, the rotating shaft 120 is driven to rotate synchronously, at this time, the code disc 170 arranged on the first connecting section 122 has the same angular velocity as the rotating disc 130, the angular velocity of the code disc 170 can be measured by the speed sensor 176, and then the angular velocity of the rotating disc 130 is obtained. In addition, by arranging the code disc 170 and the machine box 160 on the side of the machine body 110 away from the rotating disc 130, the positions of the code disc 170 and the machine box 160 are more concealed during use, which can reduce the influence of the external environment, thereby ensuring the accuracy of measurement, and the control unit can compensate and correct the rotating speed of the driving assembly 140 according to the measurement result, so as to ensure the accuracy of the final rotating speed of the rotating disc 130.
