[0046] See also Figure 1 The motor 100 of the embodiment of the present application includes a primary assembly 10 and a secondary assembly 20. The secondary assembly 20 corresponds to the primary assembly 10 and can move relative to the primary assembly 10. The secondary assembly 20 includes a housing 21, a sensor reader 22, a wire harness 23 and a wire pressing plate 24. The sensor reader 22 is arranged on the housing 21. The wire harness 23 is connected to the sensor reader 22. The wire pressing plate 24 is fixed on the housing 21, and the wire harness 23 is fixed on the housing 21.

[0047] The motor 100 includes but is not limited to a linear motor, a rotary motor, and a bidirectional motor. For example, when the motor 100 is a linear motor, the secondary assembly 20 can move relative to the primary assembly 10 along the extension direction of the housing 21; when the motor 100 is a rotary motor, the secondary assembly 20 can rotate relative to the primary assembly 10; when the motor 100 is a bidirectional motor, the secondary assembly 20 can move relative to the primary assembly 10 along the extension direction of the housing 21, and rotate relative to the primary assembly 10. In the embodiments of the present application, only the motor 100 is described as a linear motor.

[0048] Please combine Figure 2 In some embodiments, the primary component 10 includes a sensing member 13, which corresponds to the sensor reader 22, and cooperates with the sensor reader 22 to detect the position change between the secondary component 20 and the primary component 10. It should be noted that in some embodiments, the sensing member 13 is configured as a magnetic strip or a grating.

[0049] Specifically, in some embodiments, the sensing element 13 can be constructed as a magnetic strip, which is spaced apart from the sensor reader 22 and has a plurality of magnetic field sensors distributed in the axial direction (X1 / X2). The magnetic field sensor at each detection point of the magnetic strip can convert the magnetic tape strength at its location into an electrical signal and transmit it to the sensor reader 22. The sensor reader 22 can measure the magnetic field strength at each detection point through data conversion, thereby obtaining the relative position between the secondary component 20 and the primary component 10.

[0050] In other embodiments, the sensing element 13 can be constructed as a grating. When the grating moves relative to the sensor reader 22, the relative displacement of the two changes the propagation path of the light, thereby forming alternating light and dark interference fringes on the photoelectric receiver. The relative position between the secondary component 20 and the primary component 10 can be obtained by counting the number of interference fringes.

[0051] The wiring harness 23 is a structure formed by binding a plurality of wires or cables together. In the embodiment of the present application, the wiring harness 23 is electrically connected to the sensor reader 22, and the wiring harness 23 can be a signal line of the sensor reader 22, or a power line of the sensor reader 22, etc.

[0052] In some embodiments, the wire pressing plate 24 and the housing 21 are connected together in a detachable manner, so that it is convenient to repair or replace the wiring harness 23 when it is damaged, and ensure the normal operation of the sensor reader 22. Among them, the detachable connection method includes but is not limited to threaded connection or snap connection. In other embodiments, the wire pressing plate 24 and the housing 21 are connected together in a non-detachable manner, thereby improving the connection strength between the wire pressing plate 24 and the housing 21 and reducing the possibility of the wire pressing plate 24 loosening or falling off from the housing 21. Among them, the non-detachable connection method includes but is not limited to welding or bonding.

[0053] In some embodiments, the wire pressing plate 24 includes one wire pressing plate 24, which is disposed on the housing 21 and is used to fix the wire harness 23. In other embodiments, the wire pressing plate 24 includes at least two wire pressing plates 24, which are both disposed on the housing 21 and are used to fix the wire harness 23 together, thereby further reducing the possibility of the wire harness 23 moving relative to the housing 21, that is, when one wire pressing plate 24 is loosened or falls off from the housing 21, the other wire pressing plates 24 can still fix the wire harness 23 to the housing 21.

[0054] In the motor 100 of the embodiment of the present application, the sensor reader 22 is arranged on the shell 21, the wiring harness 23 is connected to the sensor reader 22, the wire pressing plate 24 is fixed on the shell 21, and the wiring harness 23 is fixed on the shell 21, thereby limiting the movement of the wiring harness 23 relative to the shell 21, thereby not only preventing the wiring harness 23 from being worn and extending the service life of the wiring harness 23, but also avoiding the sensor reader 22 from being damaged by force due to the movement of the wiring harness 23, thereby improving the stability and reliability of the sensor reader 22 and the motor 100.

[0055] The motor 100 is further described below with reference to the accompanying drawings.

[0056] See also Figure 1 In some embodiments, the wire pressing plate 24 is an electrical insulator. In other words, the wire pressing plate 24 is made of insulating material, which can effectively isolate the wire harness 23 from the surrounding environment, prevent the wire harness 23 from short circuiting or leaking electricity, and thus improve safety. It should be noted that in some embodiments, the insulating material includes but is not limited to plastic, rubber, glass or mica.

[0057] Please combine Figure 3 In some embodiments, the wire pressing plate 24 is connected to the shell 21 via a fastener 26, and at least a portion of the surface 241 of the wire pressing plate 24 that cooperates with the fastener 26 is made of metal, thereby improving the connection strength between the wire pressing plate 24 and the shell 21 and reducing the possibility of the wire pressing plate 24 falling off the shell 21.

[0058] Specifically, in some embodiments, when the wire pressing plate 24 and the housing 21 are connected by a threaded connection, the fastener 26 may be a screw, and the surface 241 of the wire pressing plate 24 that matches the fastener 26 may be the surface of the screw hole. In other embodiments, when the wire pressing plate 24 and the housing 21 are connected by welding, the fastener 26 may be solder, and the surface 241 of the wire pressing plate 24 that matches the fastener 26 may be the surface of the wire pressing plate 24 that matches the solder.

[0060] Specifically, please combine Figure 5In some embodiments, the fixing member 25 is disposed on the housing 21 and is provided with a through hole 251, and the wire harness 23 passes through the through hole 251 and is connected to the peripheral wall of the through hole 251, thereby, the fixing member 25 can fix the wire harness 23. In addition, the wire pressing plate 24 limits the fixing member 25, so that the wire harness 23 is fixed to the housing 21 through the fixing member 25, thereby, the setting of the wire pressing plate 24 can reduce the possibility of the fixing member 25 falling off from the housing 21, that is, reduce the possibility of the wire harness 23 moving relative to the housing 21, thereby not only preventing the wire harness 23 from being worn and extending the service life of the wire harness 23, but also preventing the sensor reader 22 from being damaged by force due to the movement of the wire harness 23, thereby improving the stability and reliability of the sensor reader 22 and the motor 100.

[0061] In some embodiments, the through hole 251 includes one, the wiring harness 23 includes at least one, and the at least one wiring harness 23 penetrates the through hole 251 and is connected to the peripheral wall of the through hole 251. In other embodiments, the through hole 251 includes multiple, the wiring harness 23 includes multiple, the wiring harness 23 penetrates the through hole 251 and is connected to the peripheral wall of the through hole 251, and the multiple through holes 251 correspond to the multiple wiring harnesses 23. Exemplarily, the quantitative relationship between the multiple through holes 251 and the multiple wiring harnesses 23 is one-to-one, or one-to-many, that is, one through hole 251 corresponds to one wiring harness 23; or one through hole 251 corresponds to multiple wiring harnesses 23.

[0062] In some embodiments, the fixing member 25 is an electrical insulating member. In other words, the fixing member 25 is made of an insulating material, which can effectively isolate the wiring harness 23 from the surrounding environment, prevent the wiring harness 23 from short circuiting or leaking electricity, and thus improve safety. It should be noted that in some embodiments, the insulating material includes but is not limited to plastic, rubber, glass, or mica.

[0063] See also Figure 1 and Figure 4 In some embodiments, the wire pressing plate 24 and the housing 21 enclose a receiving space 210, and the fixing member 25 is received in the receiving space 210. The provision of the receiving space 210 can facilitate the installation and positioning of the fixing member 25 on the housing 21, thereby improving the installation efficiency of the fixing member 25; on the other hand, it can reduce the space occupied by the fixing member 25 and the housing 21, thereby facilitating the miniaturization of the motor 100.

[0064] In some embodiments, the accommodating space 210 is disposed on the side of the wire pressing plate 24 facing the housing 21. Specifically, the wire pressing plate 24 includes a first side and a second side opposite to each other, the first side of the wire pressing plate 24 is opposite to the housing 21, and the accommodating space 210 is recessed from the first side of the wire pressing plate 24 toward the second side of the wire pressing plate 24. When the wire pressing plate 24 is disposed in the housing 21, the fixing member 25 is accommodated in the accommodating space 210 and is in gap fit with the inner wall of the accommodating space 210, thereby ensuring that the wire pressing plate 24 restricts the movement of the fixing member 25 relative to the housing 21, and reduces the possibility of the fixing member 25 falling off from the housing 21.

[0065] In other embodiments, the accommodating space 210 is disposed on a side of the housing 21 facing the wire pressing plate 24. Specifically, the accommodating space 210 is recessed from the outer peripheral wall 211 of the housing 21 toward the inside of the housing 21, and when the wire pressing plate 24 is disposed in the housing 21, the fixing member 25 is accommodated in the mounting groove.

[0066] In some further embodiments, a first groove is provided on one side of the wire pressing plate 24 facing the housing 21, and a second groove is provided on one side of the housing 21 facing the wire pressing plate 24, and the first groove and the second groove together form a receiving space 210. Specifically, the first groove is recessed from the first side of the wire pressing plate 24 toward the second side of the wire pressing plate 24, and the second groove is recessed from the outer peripheral wall 211 of the housing 21 toward the inside of the housing 21, and the first groove and the second groove are opposite to each other to form the receiving space 210 together, and when the wire pressing plate 24 is disposed in the housing 21, the fixing member 25 is accommodated in the receiving space 210.

[0067] See also Figure 1 In some embodiments, the outer wall 211 of the housing 21 is provided with a protection groove 213, and the wire harness 23 is at least partially accommodated in the protection groove 213. The provision of the protection groove 213 can prevent the wire harness 23 from interfering with other structures, reduce the possibility of wear of the wire harness 23, and ensure the normal operation of the sensor reader 22 and the motor 100; on the other hand, it can reduce the space occupied by the wire harness 23 and the housing 21, thereby facilitating the miniaturization of the motor 100.

[0068] In some embodiments, the outer peripheral wall 211 of the shell 21 is provided with at least two reinforcing ribs 215 , and two adjacent reinforcing ribs 215 are spaced apart from each other and form a protective groove 213 .

[0069] Specifically, the reinforcing rib 215 protrudes and extends from the outer peripheral wall 211 of the shell 21 in a direction away from the shell 21, and the wiring harness 23 is arranged in the gap (protective groove 213) between two adjacent reinforcing ribs 215. Therefore, the arrangement of the reinforcing rib 215 can prevent the wiring harness 23 from interfering with other structures and causing wear, thereby ensuring the normal operation of the sensor reader 22 and the motor 100; on the other hand, it can improve the rigidity and strength of the shell 21 and reduce the possibility of damage to the shell 21. It should be noted that in some embodiments, the extension direction of the reinforcing rib 215 is the same as the extension direction of the shell body.

[0070] In other embodiments, the outer peripheral wall 211 of the housing 21 is recessed toward the center of the housing 21 to form a protective groove 213. The wiring harness 23 is disposed in the protective groove 213, thereby preventing the wiring harness 23 from interfering with other structures and causing wear, thereby ensuring the normal operation of the sensor reader 22 and the motor 100.

[0071] See also Figure 1 and Figure 2 In some embodiments, the primary assembly 10 includes a primary core shaft 11 , and the primary core shaft 11 passes through the housing 21 . The induction element 13 is mounted on the primary core shaft 11 .

The first installation groove 110 can be recessed from the outer peripheral wall 111 of the primary core shaft 11 toward the central axis of the primary core shaft 11, and the induction member 13 is adapted to be installed in the first installation groove 110. Therefore, the setting of the first installation groove 110 can reduce the radial size of the primary core shaft 11, reduce the volume of the primary assembly 10, and facilitate the miniaturization of the motor 100.

[0073] More specifically, in some embodiments, the primary core shaft 11 includes a first split portion 113 and a second split portion 115, that is, the first split portion 113 and the second split portion 115 are connected in the axial direction (X1 / X2) to form the primary core shaft 11, and a first mounting groove 110 is provided on the outer periphery of the first split portion 113, and an open opening 120 is formed on the end surface of one end of the first split portion 113 close to the second split portion 115, and the open opening 120 is connected to the first mounting groove 110. Therefore, when the sensing component 13 is installed, the sensing component 13 can be slidably installed into the first mounting groove 110 from the open opening 120.

[0074] See also Figure 2 , Figure 6 and Figure 7In some embodiments, the primary assembly 10 further includes a stopper 15, at least a portion of which is received in the first mounting groove 110 and abuts against the sensing element 13 in the axial direction (X1 / X2). It should be noted that in some embodiments, the stopper 15 may be a rubber plug, etc., which is not limited here.

[0075] Specifically, in some embodiments, the first mounting groove 110 has a groove wall at one end away from the second split portion 115 in the axial direction (X1 / X2), and the first mounting groove 110 at one end close to the second split portion 115 in the axial direction (X1 / X2) passes through the first split portion 113. After the sensing element 13 is set in the first mounting groove 110 through the open mouth 120, the limiting element 15 is inserted into the open mouth 120 so that at least a portion of the limiting element 15 is accommodated in the first mounting groove 110, thereby The limit member 15 and the sensing member 13 are stopped in the axial direction (X1 / X2), so that the two ends of the sensing member 13 in the axial direction (X1 / X2) are respectively stopped against the groove wall of the first mounting groove 110 and the limit member 15, thereby limiting the movement of the sensing member 13 in the axial direction (X1 / X2) relative to the first split portion 113, so that the sensing member 13 can be stably installed on the first split portion 113, and at the same time, the sensing member 13 can accurately reflect the position of the first split portion 113 relative to the shell 21.

[0076] Please combine Figure 7 In some embodiments, the sensing member 13 includes a mounting portion 131 and a sensing portion 133. The mounting portion 131 has a second mounting groove extending along the axial direction (X1 / X2). The sensing portion 133 is mounted in the second mounting groove, so that the second mounting groove can accommodate the sensing portion 133. At the same time, the inner wall of the second mounting groove can also limit the outer peripheral wall of the sensing portion 133, so that the sensing portion 133 can be stably accommodated in the second mounting groove, and at the same time, the bottom wall of the second mounting groove is also suitable for supporting the sensing portion 133. Therefore, when assembling the position sensing device, the mounting portion 131 is installed in the first mounting groove 110 to ensure that the sensing portion 133 is accurately installed in the preset position, avoiding time-consuming position adjustment of the sensing portion 133, and improving the assembly efficiency of the position sensing device.

[0077] Please combine Figure 6 In some embodiments, the first mounting groove 110 includes a first groove section 1101 and a second groove section 1103. The first groove section 1101 and the second groove section 1103 are sequentially arranged and connected in the axial direction (X1 / X2), and the width of the first groove section 1101 is greater than the width of the second groove section 1103.

[0078] Specifically, in some embodiments, the first slot section 1101 and the second slot section 1103 are sequentially arranged and connected in the axial direction (X1 / X2), the first slot section 1101 is arranged close to the second split portion 115 and connected to the open port 120, and the second slot section 1103 is arranged away from the second split portion 115. The width of the first slot section 1101 is greater than the width of the second slot section 1103, and the head and the plate portion are respectively adapted to be installed on the first slot section 1101 and the second slot section 1103, that is, the head and the plate portion are respectively adapted to the width setting of the first slot section 1101 and the second slot section 1103, thereby, the width of the head is greater than the width of the plate portion, and when the sensing member 13 is assembled and the sensing portion 133 is located at a preset position, the end face of one end of the head close to the plate portion is suitable for abutting against the inner wall of one end of the first slot section 1101 close to the second slot section 1103, so as to limit the mounting portion 131 when assembling the sensing member 13, so that the assembly of the sensing member 13 is more accurate.

[0079] See also Figure 1 and Figure 2 In some embodiments, the primary assembly 10 includes an iron core 16 and a plurality of windings 17. The iron core 16 is sleeved and mounted on the peripheral wall of the primary core shaft 11. In the axial direction (X1 / X2) of the primary core shaft 11, the iron core 16 is provided with a plurality of spaced receiving grooves 161, and the plurality of windings 17 are respectively arranged in the plurality of receiving grooves 161. The secondary assembly 20 also includes a magnetic member 27, which is arranged in the housing 21. The magnetic member 27 is used to cooperate with the windings 17 so that the secondary assembly 20 can move relative to the primary assembly 10.

[0080] Specifically, in some embodiments, the iron core 16 is sleeved and installed in the second split portion 115 ( Figure 6 The shell 21 is provided with a housing 217, and the primary core shaft 11 passes through the shell 21 and is at least partially accommodated in the housing 217, that is, the second split portion 115 is accommodated in the housing 217, and at least part of the first split portion 113 is accommodated in the housing 217. The magnetic member 27 is arranged on the inner wall of the shell 21, and the iron core 16 and the winding 17 are accommodated in the housing 217 and are opposite to the magnetic member 27. In which, when the winding 17 is passed with current, the winding 17 can generate a magnetic field, and the magnetic field generated by the winding 17 can interact with the magnetic field generated by the magnetic member 27 to generate a force that drives the shell 21 to move relative to the primary core shaft 11, thereby, the secondary component 20 can move relative to the primary component 10 along the axial direction (X1 / X2) of the primary core shaft 11. It should be noted that in some embodiments, the magnetic member 27 can be a magnetic steel.

[0081] In some embodiments, the primary mandrel 11 includes a first end 116 and a second end 117, and a receiving cavity 118 that penetrates the first end 116 and the second end 117. The secondary assembly 20 also includes a secondary mandrel 28, which is disposed in the housing 21. One end of the secondary mandrel 28 penetrates the second end 117 of the primary mandrel 11 and extends into the receiving cavity 118 of the primary mandrel 11, and the other end is connected to the housing 21. When the secondary mandrel 28 moves relative to the primary mandrel 11, the housing 21 moves relative to the primary mandrel 11 along with the secondary mandrel 28.

[0082] Specifically, in some embodiments, when the housing 21 moves relative to the primary spindle 11, a portion of the secondary spindle 28 can extend into the accommodating cavity 118, that is, the accommodating cavity 118 can provide a movable space for the movement of the primary spindle 11, thereby facilitating the miniaturization design of the motor 100. In addition, the provision of the secondary spindle 28 can provide a guiding and limiting effect on the movement of the housing 21, that is, to ensure that the housing 21 moves relative to the primary spindle 11 along the axial direction (X1 / X2) of the primary spindle 11, and to prevent the housing 21 from moving relative to the primary spindle 11 along directions other than the axial direction (X1 / X2) of the primary spindle 11 (e.g., the radial direction of the primary spindle 11, etc.), resulting in the housing 21 being stuck relative to the primary spindle 11, thereby ensuring the stability of the movement of the secondary assembly 20 relative to the primary assembly 10.

[0083] See also Figure 2 In some embodiments, the motor 100 further includes a first buffer 30, which is sleeved on the peripheral wall of the primary core shaft 11 and accommodated in the accommodating cavity 118. The first buffer 30 is used to buffer the collision between the primary core shaft 11 and the housing 21. It should be noted that, in some embodiments, the material of the first buffer 30 may include but is not limited to at least one of rubber, silicone and plastic.

[0084] Specifically, in some embodiments, the peripheral wall of the primary mandrel 11 is provided with a step 119, and the step 119 is accommodated in the accommodating cavity 217. The first buffer 30 is sleeved on the peripheral wall of the primary mandrel 11 and is located on the step 119. When the secondary assembly 20 and the primary assembly 10 move relative to each other, the first buffer 30 is used to buffer the collision between the step 119 and the inner wall of the housing 21. It can be understood that in some embodiments, when the step 119 abuts against the inner wall of the housing 21, the secondary assembly 20 moves relative to the primary assembly 10 along the first direction X1 to the extreme position. The first direction X1 is the same as the positive direction X1 of the axial direction (X1 / X2) of the primary mandrel 11.

[0085] In some embodiments, the motor 100 further includes a second buffer 40, which is sleeved on the end of the primary core shaft 11 and accommodated in the accommodation cavity 118. When the secondary assembly 20 and the primary assembly 10 move relative to each other, the second buffer 40 is used to buffer the collision between the end of the primary core shaft 11 and the inner wall of the housing 21. It should be noted that, in some embodiments, the material of the second buffer 40 may include but is not limited to at least one of rubber, silicone and plastic.

[0086] It can be understood that when the end of the primary core shaft 11 abuts against the inner wall of the housing 21, the secondary assembly 20 moves relative to the primary assembly 10 along the second direction X2 to the extreme position. The second direction X2 is opposite to the first direction X1.
