[0026] First, as Figure 1 As shown, an embodiment of the present application provides a motor 100, which includes a shell 110, an electret fluid 120, a mass 130 and an electrode mechanism 140. The shell 110 has a accommodating chamber 112; the electret fluid 120 is accommodated in the accommodating chamber 112; the mass 130 is accommodated in the accommodating chamber 112; at least two electrode mechanisms 140 are arranged at both ends of the shell 110 in a first direction X, and the electrode mechanism 140 is used to generate an electric field to drive the electret fluid 120, so as to drive the mass 130 to move along the first direction X in the accommodating chamber 112.

[0027] In the motor 100 and the electronic device provided in the embodiment of the present application, the motor 100 includes a shell 110, a mass block 130, an electrode mechanism 140 and an electret fluid 120. The shell 110 has a accommodating chamber 112. The electret fluid 120 and the mass block 130 are arranged in the accommodating chamber 112. At least two electrode mechanisms 140 are arranged at both ends of the shell 110 in a first direction X. The electric field of the electrode mechanism 140 drives the electret fluid 120 to flow in the accommodating chamber 112. When the electret fluid 120 flows, it drives the mass block 130 to move in the accommodating chamber 112 along the first direction X, so that the motor 100 vibrates. By arranging the electret fluid 120 in the accommodating chamber 112, the electret fluid 120 flows in the electric field generated by the electrode mechanism 140 to drive the mass 130 to move along the first direction X, so that the motor 100 vibrates and generates a sense of vibration in the first direction X. There is no need to additionally arrange a mechanical shrapnel, thereby solving the problem in the prior art that the shrapnel of the motor 100 is deformed and twisted, fails or elastically fatigued, causing vibration and noise, and affecting the vibration performance and service life of the motor 100. In addition, the electret fluid 120 can also be used to increase the damping coefficient to ensure that after the electrode mechanism 140 stops working, the mass 130 can stop faster, so as to further improve the user experience.

[0028] Figure 1 The electret fluid is shown by a dotted line in FIG. 1 to facilitate illustrating the structure of the motor 100 .

[0029] The housing 110 has a receiving chamber 112, and the receiving chamber 112 is used to receive the electret fluid 120 and the mass block 130. The shape and size of the receiving chamber 112 can be flexibly designed, and illustratively, the receiving chamber 112 is in a cubic shape or a cylindrical shape.

[0030] For example, the "porphyrin"-based organic matter has a small energy gap between the highest occupied orbital and the lowest occupied orbital, which is conducive to the rapid transfer of electrons, so that it exhibits high redox activity. Using the organic compound "porphyrin" surrounded by a flexible and insulating structure (branched alkyl chain), a liquid material that is liquid at room temperature and can stably store electric charge can be developed. When a high voltage is applied to the liquid material, it will be electrostatically charged to form an electret liquid 120.

[0031] The mass block 130 is accommodated in the accommodating cavity 112, and the shape, size and material of the mass block 130 can be designed by oneself. Exemplarily, the material of the mass block 130 will not corrode with the electret fluid 120; Exemplarily, the mass block 130 is in a sheet shape to increase the contact area between the mass block 130 and the electret fluid 120 in the first direction X, so that the electret fluid 120 can push the mass block 130 to move. Exemplarily, the peripheral edge of the mass block 130 around the first direction X is in contact with the housing 110 to increase the contact area between the mass block 130 and the electret fluid 120 along the first direction X. The mass block 130 is provided with a plurality of hollow holes, and the electret fluid 120 can circulate through the hollow holes.

[0032] At least two electrode mechanisms 140 are disposed at both ends of the shell 110 in the first direction X. When the electrode mechanisms 140 are in a powered-on state, an electric field is formed between the two electrode mechanisms 140, and the electret fluid 120 flows in the electric field. The electret fluid 120 drives the mass block 130 to move in the accommodating cavity 112 to make the motor 100 generate a vibration.

[0033] One or more electrode mechanisms 140 may be provided at the end of the shell 110 in the first direction X. Exemplarily, the electrode mechanism 140 may be an electrode sheet. Exemplarily, one end of the shell 110 in the first direction X may be provided with one, two, or three electrode mechanisms 140.

[0034] Optionally, the electrode mechanisms 140 at both ends of the shell 110 in the first direction X correspond to each other, and the orthographic projections of the electrode mechanisms 140 located at both ends of the shell 110 in the first direction X overlap.

[0035] Exemplarily, the electrode mechanisms 140 disposed at both ends of the housing 110 in the first direction X are respectively the first electrode mechanism and the second electrode mechanism, the first electrode mechanism applies a positive voltage, the second electrode mechanism applies a negative voltage, the electret fluid 120 moves toward the first electrode mechanism or the second electrode mechanism in the first direction X, and the electret fluid 120 drives the mass block 130 to move toward the first electrode mechanism or the second electrode mechanism; then, a negative voltage is applied to the first electrode mechanism, and a positive voltage is applied to the second electrode mechanism, the electret fluid 120 moves toward the second electrode mechanism or the first electrode mechanism in the first direction X, and the electret fluid 120 drives the mass block 130 to move toward the second electrode mechanism or the first electrode mechanism, and by alternately changing the direction of the voltage applied to the electrode mechanism 140, the mass block 130 moves back and forth in the accommodating cavity 112, so that the motor 100 generates a sense of vibration. The strength of the voltage applied to the electrode mechanism 140 is adjusted to control the strength of the sense of vibration of the motor 100.

[0036] By changing the relative position of the motor 100 in the device, the motor 100 of the embodiment of the present application can be a Z-axis vibration motor, an X-axis vibration motor, or a Y-axis vibration motor.

[0037] In some embodiments, Figure 1 As shown, the motor 100 also includes a support portion 150, which is arranged in the accommodating cavity 112. The support portion 150 is connected to the shell 110 along the second direction Y. The accommodating cavity 112 includes chambers 113 arranged on both sides of the support portion 150 in the third direction Z. The first direction X, the second direction Y and the third direction Z intersect with each other. Mass blocks 130 are respectively arranged in the chambers 113 on both sides of the support portion 150, and electrode mechanisms 140 are arranged at both ends of each chamber 113 in the first direction X.

[0038] In these embodiments, the motor 100 also includes a support portion 150, which is connected to the shell 110 along the second direction Y to enhance the structural strength of the shell 110; the accommodating cavity 112 includes chambers 113 disposed on both sides of the support portion 150 in the third direction Z, and mass blocks 130 are respectively disposed in the chambers 113 on both sides of the support portion 150, and electrode mechanisms 140 are disposed at both ends of each chamber 113 in the first direction X, so that the vibration intensity of the motor 100 can be conveniently adjusted by supplying power to a specific number of electrode mechanisms 140.

[0039] Optionally, the size and shape of the support portion 150 can be designed by oneself. Exemplarily, the support portion 150 is in a cubic shape.

[0040] Optionally, the support portion 150 is disposed in the middle area of ​​the chamber 113 in the third direction Z, and the volumes of the two chambers 113 are the same, so that when the mass blocks 130 in the two chambers 113 move, the motor 100 has a uniform vibration.

[0041] Optionally, the shell 110 and the support portion 150 are integrally formed to enhance the connection strength between the two; or the shell 110 and the support portion 150 are welded or adhesively connected to facilitate adjustment of the size and shape of the support portion 150.

[0042] Optionally, the electrode mechanisms 140 corresponding to the two chambers 113 can be controlled separately. When the device is in a situation where the vibration requirement is relatively low, the electrode mechanisms 140 located at both ends of a single chamber 113 can be energized, thereby reducing the energy consumption of the motor 100 while meeting the vibration requirement of the device; when the device is in a situation where the vibration requirement is relatively high, the electrode mechanisms 140 located at both ends of the two chambers 113 are energized to enhance the vibration sensation of the motor 100.

[0043] The device may be in a situation where the vibration requirement is relatively high when the device is on a table or in a pocket. This can be done by using a sensor disposed in the device to identify the device posture to determine whether the device is in a situation where the vibration requirement is relatively high.

[0044] Optionally, according to actual conditions, n support portions 150 can be set in the accommodating cavity 112 along the third direction Z, where n>1, and the n support portions 150 divide the accommodating cavity 112 into n+1 chambers 113. Each chamber 113 includes a mass block 130. Electrode mechanisms 140 are set at both ends of each chamber 113 in the first direction X to accurately control the vibration intensity of the motor 100.

[0045] In some embodiments, Figure 1 As shown, the support portion 150 and the electret fluid 120 are insulated.

[0046] In these embodiments, the support portion 150 and the electret fluid 120 are insulated to prevent the support portion 150 from attracting the charge of the electret fluid 120 and affecting the vibration intensity of the motor 100 .

[0047] Optionally, the support portion 150 is made of an insulating material. For example, the material of the support portion 150 is PP (Polypropylene) or PE (polyethylene) or PVC (Polyvinyl chloride) or PI (Polyimide) or the like.

[0048] Optionally, the support portion 150 includes a metal material layer and an insulating material layer coated on the surface of the metal material layer. The metal material layer improves the structural strength of the support portion 150, and the insulating material layer insulates the metal material layer from the electret fluid 120.

[0050] In some embodiments, Figures 1 to 3 As shown, along the first direction X, there is a gap 151 between the two ends of the support portion 150 and the housing 110 , and the gap 151 is used to connect the two chambers 113 .

[0051] In these embodiments, along the first direction X, there is a gap 151 between the two ends of the support portion 150 and the shell 110, and the chambers 113 on both sides of the support portion 150 are interconnected through the gap 151, so that when the mass block 130 moves, the electret liquid in the chambers 113 on both sides can circulate with each other through the gap 151, and there is no need to set a hollow hole on the mass block 130, so as to increase the contact area between the mass block 130 and the electret liquid 120 in the first direction X, thereby improving the vibration performance of the motor 100.

[0052] Figure 2 and Figure 3 In FIG. 1 , the flow direction of the electret fluid 120 is indicated by an arrow.

[0053] There is a gap 151 between the supporting portion 150 and the housing 110 at both ends in the first direction X. The shape and size of the gap 151 can be designed by oneself. Exemplarily, the gap 151 is rectangular or circular.

[0054] Optionally, the support portion 150 is spaced apart from the shell 110 at the end in the first direction X to increase the size of the gap 151 and facilitate the circulation of the electret fluid 120; or the support portion 150 is at the end in the first direction X, and is connected to the shell 110 in a part of the area in the second direction Y. The support portion 150 supports the shell 110 in the first direction X, and is spaced apart from the shell 110 in another part of the area in the second direction Y to facilitate the circulation of the electret fluid 120.

[0055] See also Figure 4 , Figure 4 for Figure 2 Cross-sectional view at AA in the middle.

Through the first connecting portion 152 and the second connecting portion 131, the support portion 150 plays a role in fixing and limiting the mass block 130, thereby reducing the risk of flipping and twisting of the mass block 130 during movement, thereby improving the reliability of the motor 100.

[0058] Optionally, the first connecting portion 152 is a sliding groove or a sliding rail arranged on the supporting portion 150 and extending along the first direction X, and the second connecting portion 131 is a sliding block arranged on one end of the mass block 130 facing the supporting portion 150, and the sliding block is accommodated in the sliding groove or the sliding rail so that the mass block 130 can slide relative to the supporting portion 150; or the first connecting portion 152 is a sliding block arranged on the supporting portion 150 and extending along the first direction X, and the second connecting portion 131 is a sliding groove arranged on one end of the mass block 130 facing the supporting portion 150, and the sliding block is accommodated in the sliding groove or the sliding rail so that the mass block 130 can slide relative to the support portion 150.

[0060] In some embodiments, Figure 1 and Figure 4 As shown, the first connection portion 152 is located between the two gaps 151 along the first direction X.

[0061] In these embodiments, the first connecting portion 152 is located between the two gaps 151 along the first direction X to improve the problem that the mass block 130 is attached to the inner surface of the shell 110 and there is no electret liquid on one side of the mass block 130, so that the mass block 130 cannot move with the electret liquid 120, thereby improving the reliability of the motor 100.

[0062] Specifically, the mass block 130 and the support portion 150 are connected by a first connecting portion 152 and a second connecting portion 131, and the first connecting portion 152 is located between the two gaps 151 along the first direction X. Then, when the mass block 130 is at the end of the first connecting portion 152, the gap 151 is between the shell 110 and the first connecting portion 152, and the electret fluid 120 entering the chamber 113 through the gap 151 can still drive the mass block 130 to move.

[0063] In some embodiments, Figure 1 and Figure 4 As shown, the shell 110 is provided with third connecting parts 111 on both sides of the third direction Z, and the end of the mass block 130 away from the support part 150 is provided with a fourth connecting part 132, and the third connecting part 111 and the fourth connecting part 132 are relatively movably connected in the first direction X.

The third connecting portion 111 and the fourth connecting portion 132 are relatively movably connected in the first direction X. The shell 110 and the mass block 130 are connected through the third connecting portion 111 and the fourth connecting portion 132. The shell 110 plays a role in fixing and limiting the mass block 130, thereby reducing the risk of flipping and twisting of the mass block 130 during movement, and improving the reliability of the motor 100.

[0068] See also Figure 5 , Figure 5 This is a schematic diagram of the structure of the mass block of the motor of some embodiments of the present application.

[0069] In some embodiments, Figure 1 and Figure 5 As shown, the mass block 130 includes a weight portion 133 and an insulating layer 134 . The insulating layer 134 is coated on the outer surface of the weight portion 133 . The insulating layer 134 is used to insulate the weight portion 133 from the electret fluid 120 .

[0070] In these embodiments, the mass block 130 includes a counterweight portion 133 and an insulating layer 134. The counterweight portion 133 is used to enhance the vibration sensation of the motor 100. The insulating layer 134 is coated on the outer surface of the counterweight portion 133. The insulating layer 134 is used to insulate the counterweight portion 133 and the electret fluid 120 to avoid the problem that the counterweight portion 133 attracts the electric charge of the electret fluid 120 and affects the vibration intensity of the motor 100.

[0071] Optionally, the counterweight 133 is made of a high-density material such as a tungsten alloy block to enhance the vibration of the motor 100 .

[0072] In some embodiments, Figure 1 As shown, the peripheral edge of the mass block 130 around the first direction X is in contact with the housing 110 and the support portion 150 .

[0073] In these embodiments, the mass block 130 contacts the shell 110 and the support portion 150 around the circumferential edge in the first direction X to increase the contact area between the mass block 130 and the electret fluid 120 in the first direction X, making it easier for the electret fluid 120 to drive the mass block 130 to move, thereby improving the vibration performance of the motor 100.

[0074] Specifically, both side edges of the mass block 130 in the second direction Y contact the inner surface of the shell 110 , one side edge of the mass block 130 in the third direction Z contacts the shell 110 , and the other side edge in the third direction Z contacts the support portion 150 .

[0075] Optionally, the cross section of the mass block 130 in the first direction X has the same shape as the cross section of the chamber 113 in the first direction X, so as to reduce the difficulty of matching the mass block 130 and the chamber 113 .

[0076] In some embodiments, Figure 1 As shown, the shell 110 and the electret fluid 120 are insulated from each other, and the electrode mechanism 140 is disposed on the outer surface of the shell 110 , and the electrode mechanism 140 is insulated from the electret fluid 120 by the shell 110 .

The electrode mechanism 140 is disposed on the outer surface of the shell 110. The electrode mechanism 140 is insulated from the shell 110 and the electret fluid 120 to reduce the risk of short circuit between the electret fluid 120 and the electrode mechanism 140, thereby improving the reliability of the motor 100.

[0078] Optionally, the shell 110 is made of an insulating material. For example, the shell 110 is made of PP (Polypropylene) or PE (polyethylene) or PVC (Polyvinyl chloride) or PI (Polyimide) or the like.

[0079] Optionally, the shell 110 includes a metal material layer and an insulating material layer coated on the surface of the metal material layer, and the metal material layer is used to improve the structural strength of the shell 110, and the insulating material layer is used to insulate the metal material layer and the electret fluid 120; or an insulating material layer is only provided on the inner surface of the shell 110, so as to reduce the preparation cost of the shell 110 in the case of insulating the metal material layer and the electret fluid 120.

[0080] Optionally, the electrode mechanism 140 is connected to the outer surface of the shell 110 by means of clamping, bonding or welding to improve the connection reliability between the shell 110 and the electrode mechanism 140 .

[0081] In some embodiments, the volume V1 of the electret fluid 120 and the volume V2 of the accommodating chamber 112 satisfy 0.8*V2≤V1, which reduces the difficulty of filling the electret fluid 120 into the accommodating chamber 112 and avoids the problem of too little electret fluid 120 resulting in the inability to drive the mass block 130.

[0082] Optionally, the electret fluid 120 fills the containing chamber 112 to facilitate the electret fluid 120 to drive the mass block 130 to move, thereby enhancing the vibration sensation of the motor 100 .

[0083] Optionally, the volume V2 of the accommodating chamber 112 may be the sum of the volumes of the two chambers 113 .
