Description

Technical Field

[0001] This application relates to the field of stepper motor technology, and more particularly to a stepper motor assembly. Background Technology

[0002] A stepper motor can be installed on the actuator of a water outlet module (such as a three-way valve). As a driving element of the actuator, the stepper motor can be used to control the flow path of the water outlet module to open or close. In related technologies, replacing synchronous motors with stepper motors in the actuators of water outlet modules suitable for synchronous motors results in lower installation efficiency. Utility Model Content

[0003] This application provides a stepper motor assembly that solves the technical problem of low installation efficiency when installing a stepper motor instead of a synchronous motor in the actuator of a water outlet module suitable for synchronous motors.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides a stepper motor assembly for use as a driving element of an actuator. The stepper motor assembly includes a stepper motor and a conversion base. The stepper motor includes a motor body and a shaft. Along the axial direction of the shaft, the conversion base has a first end and a second end disposed opposite to each other. The first end is used to cooperate with the installation of the actuator. The conversion base has a mounting chamber, a portion of the motor body is disposed in the mounting chamber, and the second end is detachably connected to the motor body.

[0006] The stepper motor assembly proposed in this application embodiment has a second end detachably connected to the motor body. In this way, the stepper motor can be directly installed on the actuator through the conversion base, which improves the installation efficiency of the stepper motor and expands the application range of the stepper motor.

[0007] Optionally, the outer peripheral wall of the motor body is provided with a first outer boss, the inner peripheral wall of the mounting chamber is provided with a first inner boss, and the conversion base has a pressing device for pressing the first outer boss against the first inner boss.

[0008] The conversion base has a clamping device for pressing the first outer boss against the first inner boss, which enables the stepper motor to be firmly connected to the conversion base and improves the stability of the stepper motor assembly operation.

[0009] Optionally, the clamping device has a first mating part, and along the axial direction of the shaft, a first outer boss may optionally abut against the first inner boss and the first mating part.

[0010] The first outer boss can selectively abut against the first inner boss and the first mating part, so that the stepper motor and the conversion base are firmly fixed, thereby improving the stability and reliability of the stepper motor assembly.

[0011] Optionally, the first mating part protrudes from the inner peripheral wall of the mounting chamber, and a first groove is provided on the first outer boss. Along the axial direction of the shaft, the first groove passes through the first outer boss, and along the radial direction of the shaft, the first groove passes through the outer peripheral surface of the first outer boss. The first mating part is adapted to pass through the first groove along the axial direction of the shaft to abut against the first outer boss.

[0012] The first mating part is adapted to pass through the first groove along the axial direction of the shaft to abut against the first outer boss, which can facilitate the installation of the stepper motor and the conversion base together and improve the installation efficiency of the stepper motor assembly.

[0013] Optionally, there are multiple first mating parts and multiple first grooves. Along the circumference of the shaft, multiple first mating parts are spaced apart, and multiple first grooves are spaced apart, with each of the multiple first mating parts corresponding to one of the multiple first grooves.

[0014] Multiple first mating parts are spaced apart along the circumference of the shaft, providing multi-point support between the first inner boss and the multiple first mating parts, and allowing the stepper motor and the conversion base to be installed more securely together.

[0015] Optionally, the clamping device has a first fastener, which is detachably disposed at the second end and is adapted to pass through the second end to extend into the mounting chamber.

[0016] The first fastener is detachably located at the second end, which makes it easy to install the stepper motor onto the conversion base and improves the installation efficiency of the stepper motor.

[0017] Optionally, the second end is provided with a plurality of first holes for the first fastener to engage, and the plurality of first holes are spaced apart along the circumference of the shaft.

[0018] Multiple first holes are spaced apart, so that multiple first fasteners can abut against the first outer boss respectively. This forms a multi-point support between the multiple first fasteners and the first outer boss, making the stepper motor more firmly fixed on the conversion base.

[0019] Optionally, the outer peripheral wall of the conversion base is provided with a first limiting channel, at least a portion of which penetrates the inner peripheral wall of the mounting chamber to communicate with the mounting chamber, and the clamping device is inserted into the first limiting channel and at least a portion of the clamping device extends into the mounting chamber.

[0020] The clamping device is inserted into the first limiting channel and at least a portion of the clamping device extends into the mounting chamber, which facilitates the assembly of the stepper motor and the conversion base, improving the installation efficiency of the stepper motor assembly.

[0021] Optionally, there are two first limiting channels, which are spaced apart. The clamping device includes a first rod and two second rods. The two second rods are located at both ends of the first rod along its length and extend in the same direction. Each first rod is inserted into the corresponding first limiting channel and extends at least partially into the mounting chamber.

[0022] Along the axial direction of the shaft, the first outer boss is positioned between the two second rods and the first inner boss, making the stepper motor and the conversion base more firmly fixed together.

[0023] Optionally, the conversion base has a clamping device, which is configured as an elastic locking member to limit one end of the motor body mounting shaft along the axial direction of the shaft within the mounting cavity. The elastic locking member includes a first elastic locking plate and a second elastic locking plate, one end of which is connected by a connecting plate, and the other ends of which are separated to form an elastic locking opening. The elastic locking opening is used for radial insertion along the motor body so that the first and second elastic locking plates simultaneously clamp the motor body and the conversion base.

[0024] The elastic locking port is used to insert along the radial direction of the motor body so that the first elastic locking plate and the second elastic locking plate simultaneously clamp the motor body and the conversion base. This allows the first elastic locking plate and the second elastic locking plate to clamp the conversion base and the stepper motor, preventing the motor body and the conversion base from separating from each other in the axial direction of the shaft.

[0025] Optionally, the outer peripheral wall of the motor body is provided with a first outer boss, and the inner peripheral wall of the mounting chamber is provided with a first inner boss. The first inner boss abuts against one end of the mounting shaft of the motor body. The conversion base has a first end face and a second end face that are arranged opposite to each other. The first end face faces the stepper motor, and the second end face faces away from the stepper motor. The first elastic locking plate is provided with a first mating hole, and the second elastic locking plate is provided with a second mating hole. Along the axial direction of the shaft, the first mating hole has a first inner wall and a second inner wall that are spaced apart and arranged opposite to each other. The first inner wall and the second inner wall abut against the first outer boss and the second end face, respectively. The second mating hole has a third inner wall and a fourth inner wall that are spaced apart and arranged opposite to each other. The third inner wall and the fourth inner wall abut against the first outer boss and the second end face, respectively.

[0026] In this way, the first and second elastic locking plates can press one end of the motor body mounting shaft against the first inner boss, thereby restricting the separation of the motor body and the conversion base from each other in the axial direction of the shaft and improving the assembly efficiency of the stepper motor and the conversion base.

[0027] Optionally, the outer peripheral wall of the motor body is provided with a first external boss, and the conversion base has a first end face and a second end face that are arranged opposite to each other. The first end face faces the stepper motor, and the second end face faces away from the stepper motor. The first end face abuts against the first external boss. The first elastic locking plate is provided with a first mating hole, and the second elastic locking plate is provided with a second mating hole. Along the axial direction of the shaft, the first mating hole has a first inner wall and a second inner wall that are spaced apart and arranged opposite to each other. The first inner wall and the second inner wall abut against the first external boss and the second end face, respectively. The second mating hole has a third inner wall and a fourth inner wall that are spaced apart and arranged opposite to each other. The third inner wall and the fourth inner wall abut against the first external boss and the second end face, respectively.

[0028] The third and fourth inner walls abut against the first outer boss and the second end face, respectively. In this way, the first and second elastic locking plates can press one end of the motor body mounting shaft against the first inner boss, thereby restricting the separation of the motor body and the conversion base from each other in the axial direction of the shaft. The stepper motor and the conversion base are fixed together by such a simple hole structure as the first and second mating holes, which can improve the assembly efficiency of the stepper motor and the conversion base.

[0029] Optionally, the outer peripheral wall of the conversion base is provided with a second groove, the second groove having a second end face facing away from the second end.

[0030] At least a portion of the first elastic locking plate and at least a portion of the second elastic locking plate can be located within the second groove, which facilitates the second inner wall abutting against the second end face and the fourth inner wall abutting against the second end face, thereby improving the assembly efficiency of the stepper motor assembly.

[0061] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0062] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0063] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0065] Currently, the on / off state or flow channel switching of water outlet modules (such as three-way valves) on the market is generally controlled by an actuator. The driving element of the actuator typically includes a synchronous motor or a stepper motor. Due to its special structure, when a synchronous motor is used in the actuator of the first water outlet module (the actuator of the first water outlet module is adapted to a synchronous motor), the shaft of the synchronous motor can only provide the pushing force, and a spring is required for reset. However, when a stepper motor is used in the actuator of the second water outlet module (the actuator of the second water outlet module is adapted to a stepper motor), because the stepper motor can freely control the extension and retraction of its shaft, the stepper motor can freely pull the valve stem, and the actuator of the second water outlet module does not require a reset spring. Therefore, in the actuator of the first water outlet module, the synchronous motor can be replaced with a stepper motor. The stepper motor is installed in the actuator of the first water outlet module, so that the actuator of the first water outlet module can also freely control the stroke of the valve stem under the dual action of the return spring and the stepper motor. Most water outlet modules on the market are first water outlet modules. If the entire actuator of the first water outlet module is replaced, the cost is too high. However, by using a stepper motor as the drive device to replace the synchronous motor and installing it in the actuator of the first water outlet module, there is no need to replace the actuator of the first water outlet module, which greatly reduces the cost.

[0066] In related technologies, the housing of a stepper motor is modified to fit the shape of the actuator for mounting the first water outlet module. However, a stepper motor with an unmodified housing cannot be directly mounted on the actuator of the first water outlet module. The housing of the stepper motor needs to be remanufactured using a process that is cumbersome and inefficient.

[0067] In view of this, embodiments of this application propose a stepper motor assembly, which includes a stepper motor and a conversion base. The stepper motor includes a motor body and a shaft. Along the axial direction of the shaft, the conversion base has a first end and a second end disposed opposite to each other. The first end is used to cooperate with the installation of an actuator. The conversion base has a mounting chamber, a portion of the motor body is disposed in the mounting chamber, and the second end is detachably disposed in the motor body.

[0068] In the above scheme, the second end is detachably connected to the motor body, so that the stepper motor can be directly installed on the actuator of the water outlet module through the conversion base, which improves the installation efficiency of the stepper motor and expands the application range of the stepper motor.

[0069] For ease of explanation, the following embodiments use a stepper motor assembly according to an embodiment of this application as an example.

[0070] The water outlet module disclosed in this application is the original water outlet module that uses a synchronous motor. The stepper motor is installed in the actuator of the original water outlet module that uses a synchronous motor through a conversion base.

[0072] Please refer to Figures 1 to 5 In this embodiment, the stepper motor assembly 1000 is used as a driving element of the actuator. The stepper motor assembly 1000 includes a stepper motor 100 and a conversion base 110. The stepper motor 100 includes a motor body 101 and a shaft 102. Along the axial direction Y of the shaft, the conversion base 110 has a first end 111 and a second end 112 disposed opposite to each other. The first end 111 is used to cooperate with the installation of the actuator. The conversion base 110 has a mounting chamber 113. A portion of the motor body 101 is disposed in the mounting chamber 113, and the second end 112 is detachably disposed on the motor body 101.

[0073] The water outlet module can be a three-way valve or a four-way valve, or other valve body with the function of controlling the water flow channel or switching the flow path. The actuator of the water outlet module is used to control the opening and closing or switching of the water outlet module's flow path, and the conversion base 110 is used to connect the stepper motor 100 and the actuator of the water outlet module. For example, the first end 111 of the conversion base 110 is detachably disposed on the actuator, and the stepper motor 100 is detachably disposed on the second end 112 of the conversion base 110. In this way, the stepper motor 100 can be directly installed on the water outlet module through the conversion base 110, improving the installation efficiency of the stepper motor 100 and expanding the application range of the stepper motor 100.

[0074] Part of the motor body 101 is disposed in the mounting chamber 113. When the stepper motor 100 is installed together with the conversion base 110, the motor body 101 of the stepper motor 100 is located in the mounting chamber 113. When the stepper motor 100 is separated from the conversion base 110, the motor body 101 is separated from the mounting chamber 113.

[0075] For example, a pivot hole is provided on the bottom wall of the conversion base 110. The pivot hole is located at the first end 111 of the conversion base 110. The pivot hole passes through the bottom wall of the conversion base 110 and communicates with the mounting chamber 113. When the stepper motor 100 and the conversion base 110 are installed, the shaft 102 first enters the mounting chamber 113, and then extends from the mounting chamber 113 into the pivot hole. The first end 111 cooperates with the actuator of the water outlet module, so that the shaft 102 can drive the actuator of the water outlet module, thereby controlling the water outlet module.

[0076] In some embodiments, the first end 111 of the conversion base 110 is provided with a wire slot, and the conversion base 110 is fixedly connected to the actuator of the water outlet module through the wire slot.

[0077] In some embodiments, the stepper motor 100 further includes a plug-in terminal 180 that protrudes from the motor body 101.

[0078] In some embodiments, the first end 111 of the conversion base 110 is provided with a slot that is identical in shape to the synchronous motor installed on the water outlet module. It can be inserted into the water outlet module through the slot to realize the application of the stepper motor 100 to the water outlet module of the synchronous motor.

[0079] Please refer to Figures 1 to 5 In this embodiment, the outer peripheral wall of the motor body 101 is provided with a first outer protrusion 120, the inner peripheral wall of the mounting chamber 113 is provided with a first inner protrusion 130, and the conversion base 110 has a pressing device 190 for pressing the first outer protrusion 120 against the first inner protrusion 130.

[0080] Along the axial direction Y of the shaft, the clamping device 190 clamps the first outer boss 120, and the clamping device 190 presses the first outer boss 120 and the first inner boss 130 together, so that the stepper motor 100 and the conversion base 110 can be firmly connected, improving the stability of the stepper motor assembly 1000 operation.

[0081] Please refer to Figures 1 to 5 In this embodiment, the clamping device 190 has a first mating part 140, and along the axial direction Y of the shaft, the first outer boss 120 can selectively abut against the first inner boss 130 and the first mating part 140.

[0082] The first outer boss 120 protrudes from the outer peripheral wall of the stepper motor 100, and the first inner boss 130 protrudes from the inner peripheral wall of the mounting chamber 113. When the stepper motor 100 is mounted on the conversion base 110, along the axial direction Y of the shaft, the first outer boss 120 is disposed between the first inner boss 130 and the first mating part 140 and abuts against the first inner boss 130 and the first mating part 140 respectively. Along the axial direction Y of the shaft, the first outer boss 120 of the stepper motor 100 is blocked by the first inner boss 130 and the first mating part 140, and the stepper motor 100 cannot move in the axial direction Y of the shaft. The outer peripheral surface of the first outer boss 120 and the inner peripheral surface of the mounting chamber 113 are fitted together, for example, they can be an interference fit. Along the radial X of the shaft, the stepper motor 100 cannot move, thereby firmly mounting the stepper motor 100 on the conversion base 110, preventing the stepper motor 100 from separating from the conversion base 110, and improving the stability and reliability of the stepper motor assembly 1000.

[0083] Please refer to Figures 1 to 5 In this embodiment, the first mating part 140 protrudes from the inner peripheral wall of the mounting chamber 113, and the first outer boss 120 is provided with a first groove 121. Along the axial direction Y of the shaft, the first groove 121 penetrates the first outer boss 120, and along the radial direction X of the shaft, the first groove 121 penetrates the outer peripheral surface of the first outer boss 120. The first mating part 140 is adapted to pass through the first groove 121 along the axial direction Y of the shaft to abut against the first outer boss 120.

[0084] Before the conversion base 110 is assembled onto the stepper motor 100, the first mating part 140 and the first groove 121 can be opposite each other along the axial direction Y of the shaft. Then, the first mating part 140 of the conversion base 110 passes through the first groove 121, so that the first outer boss 120 is located between the first inner boss 130 and the first mating part 140. Then, the stepper motor 100 or the conversion base 110 is rotated so that the first mating part 140 and the first groove 121 are not opposite each other along the axial direction Y of the shaft. In this way, along the axial direction Y of the shaft, the first outer boss 120 can abut against the first mating part 140 and the first inner boss 130 respectively, so that the stepper motor 100 and the conversion base 110 are firmly fixed, improving the stability and reliability of the stepper motor assembly 1000.

[0085] For example, the first outer boss 120 has a first surface facing the conversion base 110 and a second surface facing away from the conversion base 110. Along the axial direction Y of the shaft, the first surface can abut against the first inner boss 130, and the second surface can optionally abut against the first mating part 140.

[0086] Furthermore, the first mating part 140 is adapted to pass through the first groove 121 along the axial direction Y of the shaft to abut against the first outer boss 120, which facilitates the installation of the stepper motor 100 and the conversion base 110 together and improves the installation efficiency of the stepper motor assembly 1000.

[0087] Please refer to Figures 1 to 5 In this embodiment, there are multiple first mating parts 140 and multiple first grooves 121. Along the circumference of the shaft 102, multiple first mating parts 140 are spaced apart, and multiple first grooves 121 are spaced apart. Each of the multiple first mating parts 140 corresponds to one of the multiple first grooves 121.

[0088] When the stepper motor 100 is assembled with the conversion base 110, along the axial direction Y of the shaft, the first outer boss 120 abuts against the first inner boss 130 and a plurality of first mating parts 140 respectively. The arrangement of the plurality of first mating parts 140 provides multi-point support between the first inner boss 130 and the plurality of first mating parts 140, and the stepper motor 100 and the conversion base 110 are more firmly installed together.

[0089] Along the circumference of the shaft 102, the spacing between the multiple first mating parts 140 can be the same as the spacing between the multiple first grooves 121. During the installation of the conversion base 110 and the stepper motor 100, along the axial direction Y of the shaft, the multiple first mating parts 140 and the multiple first grooves 121 can correspond one-to-one, and the multiple first mating parts 140 can pass through the corresponding first grooves 121.

[0090] For example, the number of first mating portions 140 may be less than the number of first grooves 121.

[0091] In some embodiments, the first mating part 140 is configured as a claw structure.

[0092] Please refer to Figures 1 to 6 In this embodiment, the clamping device 190 has a first fastener 150, which is detachably disposed at the second end 112 and is adapted to pass through the second end 112 to extend into the mounting chamber 113.

[0093] The first fastener 150 can be constructed as a screw structure or a bolt structure, etc. A mounting part can be provided on the second end 112, and the first fastener 150 can pass through the mounting part along the radial direction X of the shaft and extend into the mounting chamber 113.

[0094] When the first fastener 150 is set at the second end 112, the stepper motor 100 is assembled with the conversion base 110. Along the axial direction Y of the shaft, the first outer boss 120 is set between the first fastener 150 and the first inner boss 130. The first outer boss 120 abuts against the first fastener 150 and the first inner boss 130 respectively. When the first fastener 150 is not set at the second end 112, the first fastener 150 does not abut against the first outer boss 120, and the stepper motor 100 can be removed from the conversion base 110.

[0095] The first fastener 150 is detachably mounted on the second end 112, which makes it easy to install the stepper motor 100 onto the conversion base 110 and improves the installation efficiency of the stepper motor 100.

[0096] Please refer to Figures 1 to 6 In this embodiment, the second end 112 is provided with a plurality of first holes for the first fastener 150 to engage with, and the plurality of first holes are spaced apart along the circumference of the shaft 102.

[0097] For example, the first hole can be provided on the mounting part. Along the circumference of the shaft 102, multiple mounting parts are spaced apart at the second end 112. Each mounting part is provided with a first hole. Multiple first fasteners 150 pass through the corresponding first holes and extend into the mounting chamber 113. Multiple first fasteners 150 can abut against the first outer boss 120 respectively. In this way, multiple first fasteners 150 and the first outer boss 120 form multi-point support, and the stepper motor 100 is more firmly fixed on the conversion base 110.

[0098] Please refer to Figures 1 to 5 as well as Figure 9 In this embodiment, the outer peripheral wall of the conversion base 110 is provided with a first limiting channel 160. At least a portion of the first limiting channel 160 penetrates the inner peripheral wall of the mounting chamber 113 to communicate with the mounting chamber 113. The pressing device 190 is inserted into the first limiting channel 160 and at least a portion of the pressing device 190 extends into the mounting chamber 113.

[0099] For example, along the radial direction X of the shaft, at least a portion of the first limiting channel 160 passes through the inner peripheral wall of the mounting chamber 113 to communicate with the mounting chamber 113, and along the axial direction Y of the shaft, a portion of the clamping device 190 extending into the mounting chamber 113 abuts against the first outer boss 120, the first outer boss 120 being disposed between the clamping device 190 and the first inner boss 130, and the clamping device 190 being detachably disposed in the first limiting channel 160.

[0100] The clamping device 190 is inserted into the first limiting channel 160 and at least a portion of the clamping device 190 extends into the mounting chamber 113, which facilitates the assembly of the stepper motor 100 with the conversion base 110 and improves the installation efficiency of the stepper motor assembly 1000.

[0101] Please refer to Figures 1 to 5 as well as Figure 9 In this embodiment, there are two first limiting channels 160, which are spaced apart. The pressing device 190 includes a first rod 141 and two second rods 142. The two second rods 142 are located at both ends of the first rod 141 along its length and extend in the same direction. Each first rod 141 is inserted into and cooperates with the corresponding first limiting channel 160 and extends at least partially into the mounting chamber 113.

[0102] The length extension direction of the first rod 141 and the length extension direction of the second rod 142 can be perpendicular to each other. The first limiting channel 160 can be set at intervals. The two second rods 142 can be inserted into the first limiting channel 160. The parts of the two second rods 142 that extend into the mounting chamber 113 can abut against the first outer boss 120. Along the axial direction Y of the shaft, the first outer boss 120 is set between the two second rods 142 and the first inner boss 130, so that the stepper motor 100 and the conversion base 110 are more firmly fixed together.

[0103] The first direction is parallel to the radial X direction of the shaft. Along the first direction, the two second rods 142 are located at both ends of the motor housing, so that the stepper motor 100 and the conversion base 110 are more firmly assembled together.

[0104] Please refer to Figure 7 and Figure 8 In this embodiment, the conversion base 110 has a clamping device 190, which is configured as an elastic engaging member 200 to limit one end of the motor body 101 mounting shaft 102 along the axial direction Y of the shaft within the mounting chamber 113. The elastic engaging member 200 includes a first elastic engaging plate 210 and a second elastic engaging plate 220. One end of the first elastic engaging plate 210 and the second elastic engaging plate 220 are connected by a connecting plate 240. The other ends of the first elastic engaging plate 210 and the second elastic engaging plate 220 are separated to form an elastic engaging opening 230. The elastic engaging opening 230 is used to insert along the radial direction of the motor body 101 so that the first elastic engaging plate 210 and the second elastic engaging plate 220 simultaneously clamp the motor body 101 and the conversion base 110.

[0105] The distance between the other end of the first elastic locking plate 210 and the other end of the second elastic locking plate 220 can be adjusted. After one end of the motor body 101 mounting shaft 102 is installed into the mounting chamber 113, during the process of the elastic locking member 200 being inserted into the stepper motor 100 and the conversion base 110 along the radial X direction of the shaft, the distance between the other end of the first elastic locking plate 210 and the other end of the second elastic locking plate 220 can be increased. The dimension of the elastic locking opening 230 in the radial X direction of the shaft... When the stepper motor 100 and the conversion base 110 have been inserted into the elastic locking port 230, the distance between the other end of the first elastic locking plate 210 and the other end of the second elastic locking plate 220 can be reduced, and the size of the elastic locking port 230 in the radial X direction of the shaft can be reduced. This allows the first elastic locking plate 210 and the second elastic locking plate 220 to clamp the conversion base 110 and the stepper motor 100, preventing the motor body 101 and the conversion base 110 from separating from each other in the axial Y direction of the shaft.

[0106] The elastic locking slot 230 is used to insert along the radial direction of the motor body 101 so that the first elastic locking plate 210 and the second elastic locking plate 220 simultaneously clamp the motor body 101 and the conversion base 110. In this way, the first elastic locking plate 210 and the second elastic locking plate 220 clamp the motor body 101 and the conversion base 110 in the axial direction Y of the shaft through elastic deformation, which simplifies assembly and reduces installation costs.

[0107] Please refer to Figures 7 to 8 In this embodiment, the outer peripheral wall of the motor body 101 is provided with a first outer boss 120, and the inner peripheral wall of the mounting chamber 113 is provided with a first inner boss 130. The first inner boss 130 abuts against one end of the mounting shaft 102 of the motor body 101. The conversion base 110 has a first end face 114 and a second end face 115 arranged opposite to each other. The first end face 114 faces the stepper motor 100, and the second end face 115 faces away from the stepper motor 100.

[0108] The first elastic locking plate 210 is provided with a first mating hole 211, and the second elastic locking plate 220 is provided with a second mating hole 221. Along the axial direction Y of the shaft, the first mating hole 211 has a first inner wall 212 and a second inner wall 213 that are spaced apart and opposite to each other. The first inner wall 212 and the second inner wall 213 respectively abut against the first outer boss 120 and the second end face 115. The second mating hole 221 has a third inner wall 222 and a fourth inner wall 223 that are spaced apart and opposite to each other. The third inner wall 222 and the fourth inner wall 223 respectively abut against the first outer boss 120 and the second end face 115.

[0109] Along the axial direction Y of the shaft, the shaft 102 is located at the end of the motor body 101 facing the conversion base 110. This end of the motor body 101 abuts against the first inner boss 130, which supports the motor body 101. The first outer boss 120 can be spaced apart from the first end face 114, or it can abut against the first end face 114. In this embodiment, the position of the first outer boss 120 is not restricted. The first inner wall 212 and the second inner wall 213 abut against the first outer boss 120 and the second end face 115, respectively. The third inner wall 222 and the fourth inner wall 223 respectively abut against the first outer boss 120 and the second end face 115. In this way, the first elastic locking plate 210 and the second elastic locking plate 220 can press one end of the motor body 101 mounting shaft 102 against the first inner boss 130, thereby restricting the separation of the motor body 101 and the conversion base 110 from each other in the axial direction Y of the shaft. The stepper motor 100 and the conversion base 110 are fixed together by the simple hole structure of the first mating hole 211 and the second mating hole 221, which can improve the assembly efficiency of the stepper motor 100 and the conversion base 110.

[0110] Please refer to Figures 7 to 8 In this embodiment, the outer peripheral wall of the motor body 101 is provided with a first outer boss 120, and the conversion base 110 has a first end face 114 and a second end face 115 arranged opposite to each other. The first end face 114 faces the stepper motor 100, and the second end face 115 faces away from the stepper motor 100. The first end face 114 abuts against the first outer boss 120. The first elastic locking plate 210 is provided with a first mating hole 211, and the second elastic locking plate 220 is provided with a second mating hole 221. Along the axial direction Y of the shaft, the first mating hole 211 has a first inner wall 212 and a second inner wall 213 arranged at intervals and opposite to each other. The first inner wall 212 and the second inner wall 213 abut against the first outer boss 120 and the second end face 115, respectively. The second mating hole 221 has a third inner wall 222 and a fourth inner wall 223 arranged at intervals and opposite to each other. The third inner wall 222 and the fourth inner wall 223 abut against the first outer boss 120 and the second end face 115, respectively.

[0111] The first end face 114 serves as a support for the first outer protrusion 120. The first elastic locking plate 210 and the second elastic locking plate 220 can press the first outer protrusion 120 against the first end face 114, thereby pressing the stepper motor 100 against the conversion base 110. In this way, the first elastic locking plate 210 and the second elastic locking plate 220 can press the first outer protrusion 120 against the first end face 114, thereby restricting the separation of the motor body 101 and the conversion base 110 from each other in the axial direction Y of the shaft, and improving the assembly efficiency of the stepper motor 100 and the conversion base 110.

[0112] Please refer to Figure 7and Figure 8 In this embodiment, the outer peripheral wall of the conversion base 110 is provided with a second groove 170, and the second groove 170 has a second end face 115 facing away from the second end 112.

[0113] Along the axial direction Y of the shaft, the second end face 115 is away from the second end 112. At least a portion of the first elastic engaging plate 210 and at least a portion of the second elastic engaging plate 220 can be located in the second groove 170, which facilitates the second inner wall 213 to abut against the second end face 115 and the fourth inner wall 223 to abut against the second end face 115, thereby improving the assembly efficiency of the stepper motor assembly 1000.

[0114] Furthermore, the second groove 170 also provides guidance for the installation of the first resilient locking plate 210 and the second resilient locking plate 220.
