[0031] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0033] In conjunction with Figure 1 , the user's ear 500 may include physiological parts such as the external auditory canal (ear meatus) 501, the cavum concha 502, the cymba concha 503, the triangular fossa 504, the antihelix 505, the scaphoid 506, the helix 507, and the tragus 508. Although the external auditory canal 501 has a certain depth and extends to the eardrum, for ease of description and in conjunction with Figure 1 , this application, unless otherwise specified, specifically refers to the external auditory canal 501 as its entrance away from the eardrum (i.e., the ear canal). Furthermore, physiological parts such as the cavum concha 502, the cymba concha 503, and the triangular fossa 504 have a certain volume and depth; and the cavum concha 502 is directly connected to the external auditory canal 501, which can be simply regarded as the aforementioned ear canal being located at the bottom of the cavum concha 502.

[0034] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. In order to facilitate description and reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR. Therefore, in this application, descriptions such as "the user wears the earphones 100", "the earphones 100 are in a wearing state" and "in a wearing state" may refer to the earphones 100 described in this application being worn on the ears of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphones 100 worn by different users and the earphones 100 worn on the ears of the aforementioned simulator, but such differences should be tolerated.

[0035] 1 to 4 , the earphone 100 may include a movement module 1 and an ear hook 2. The movement module 1 may include a housing assembly 10, a battery assembly 20, and a drive assembly 30. The ear hook 2 may be hook-shaped, and the earphone 100 may be worn near the ear canal of the user's ear through the ear hook 2 but not blocking the ear canal. The ear hook 2 may be connected to the housing assembly 10 by snap-fitting with glue, or by threading. In the worn state, the movement module 1 is located on the front side of the ear, and the ear hook 2 is at least partially located on the back side of the user's ear, so that the earphone 100 is hung on the ear. In some embodiments, the housing assembly 10 is also referred to as a housing.

[0036] Referring to Figures 3, 4, and 5, the housing assembly 10 forms a housing space, which includes a first housing space 121a and a second housing space 122a. The battery assembly 20 is installed along a first predetermined assembly direction Z1 and accommodated in the first housing space 121a. The drive assembly 30 is installed along a second predetermined assembly direction Z2 and accommodated in the second housing space 122a. The drive assembly 30 includes a speaker for providing air-conducted sound to the external auditory canal of the user's ear. The battery assembly 20 includes a top wall surface and a bottom wall surface spaced apart along the thickness direction (not shown), and a peripheral wall surface 21 connecting the top and bottom walls.

[0037] Specifically, in one embodiment, the housing assembly 10 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 are connected to each other and cover each other to form the aforementioned accommodating space (including the first accommodating space 121a and the second accommodating space 122a), and the battery assembly 20 and the driving assembly 30 are respectively accommodated in the accommodating space, that is, the battery assembly 20 is accommodated in the first accommodating space 121a, and the driving assembly 30 is accommodated in the second accommodating space 122a.

[0038] The first preset assembly direction Z1 and the second preset assembly direction Z2 are set at an acute angle. In other words, the intersection angle θ between the positive direction of the second preset assembly direction Z2 and the projection of the positive direction of the first preset assembly direction Z1 in the reference plane is an acute angle. In some embodiments, the reference plane can be a plane parallel to or coplanar with the plane in which the first preset assembly direction Z1 and the second preset assembly direction Z2 are located. In some embodiments, the reference plane can be an XY plane formed by the X direction and the Y direction as shown in Figure 3, that is, a plane formed by the long axis direction and the thickness direction of the movement module 1. Optionally, the intersection angle of the projection of the positive direction of the second preset assembly direction Z2 and the positive direction of the first preset assembly direction Z1 in the reference plane is located on the side of the shell facing the user's ear. In one embodiment, the intersection angle θ between the positive direction of the second preset assembly direction Z2 and the positive direction of the first preset assembly direction Z1 is between 10° and 14° or between 11° and 14°. For example, the intersection angle θ can be 10°, 10.5°, 11°, 11.5°, 12°, 12.5°, 13°, 13.5°, or 14°. In this case, the driver assembly 30 is tilted relatively more relative to the battery assembly 20, and the projected length of the driver assembly 30 in the first direction X is reduced, which is conducive to reducing the length of the housing assembly 10 in the first direction X, reducing the volume of the movement module, making the earphones as a whole more compact, easier for users to carry and wear, and improving the user experience.

[0039] In some embodiments, referring to Figures 3 to 5 , a first stopper 1211 is disposed within the first accommodating space 121a. The projections of the first stopper 1211 and the battery assembly 20 on a cross section perpendicular to the first predetermined assembly direction Z1 do not overlap, and the first stopper 1211 is used to limit the position of the battery assembly 20. Specifically, the first stopper 1211 is disposed on one side of the battery assembly 20 in a direction perpendicular to the first predetermined assembly direction Z1. This allows the first stopper 1211 to abut against a peripheral wall surface 21 of the battery assembly 20 parallel to the first predetermined assembly direction Z1. This allows the first stopper 1211 to effectively limit the movement of the battery assembly 20 relative to the housing assembly 10 within a plane perpendicular to the first predetermined assembly direction Z1, effectively improving the stability of the connection between the battery assembly 20 and the housing assembly 10, and thereby effectively preventing noise generated by relative movement between the battery assembly 20 and the housing assembly 10 during operation of the earphones 100, thereby effectively improving the sound quality of the earphones 100 and enhancing the user's listening experience.

[0040] In some embodiments, referring to Figures 3, 4, and 5, the first limiting portion 1211 is used to at least limit the battery assembly 20 from rotating about the first preset assembly direction Z1 within a plane perpendicular to the first preset assembly direction Z1. For example, the peripheral wall surface 21 of the battery assembly 20 is parallel to the first preset assembly direction Z1 (or in some embodiments, there is an angle between the peripheral wall surface 21 and the first preset assembly direction Z1, and the angle θ ranges from 0° to 5°), and a portion of the peripheral wall surface 21 protrudes in a direction perpendicular to the first preset assembly direction Z1 to form a limiting protrusion. Exemplarily, when the battery assembly 20 is installed in the first accommodating space 121a along the first preset assembly direction Z1, the limiting protrusion on the peripheral wall surface 21 abuts against the first limiting portion 1211, thereby effectively limiting the rotation of the battery assembly 20 around the first preset assembly direction Z1, thereby effectively improving the stability of the connection between the battery assembly 20 and the outer shell assembly 10, and further effectively preventing the noise generated by the relative movement of the battery assembly 20 and the outer shell assembly 10 when the earphone 100 is working, thereby effectively improving the sound quality of the earphone 100 and improving the user's listening effect. In some embodiments, based on the above embodiments, while the first limiting portion 1211 abuts against the side of the limiting protrusion parallel to the first preset assembly direction Z1 on at least one side parallel to the first preset assembly direction Z1, the first limiting portion 1211 also extends in a direction perpendicular to the first preset assembly direction Z1 to the peripheral wall surface 21 of the battery assembly 20 and abuts against the peripheral wall surface 21. Based on this, the first limiting portion 1211 is not only used to limit the rotation of the battery assembly 20 around the first preset assembly direction Z1 in a plane perpendicular to the first preset assembly direction Z1, but also plays a certain limiting role in the movement of the battery assembly 20 relative to the outer shell assembly 10 in a plane perpendicular to the first preset assembly direction Z1, thereby further improving the stability of the connection between the battery assembly 20 and the outer shell assembly 10.

[0041] In some embodiments, referring to Figures 3, 4 and 5, the battery assembly 20 has a thickness direction (not marked in the figure), and the angle between the first preset assembly direction Z1 and the thickness direction of the battery assembly 20 is in the range of 0° to 5°. Specifically, the battery assembly 20 has a thickness direction, wherein the angle between the first preset assembly direction Z1 and the thickness direction of the battery assembly 20 is in the range of 0° to 5°. Based on this setting, the size of the outer shell assembly 10 in the second direction Y can be effectively reduced. In one embodiment, the first preset assembly direction Z1 and the thickness direction of the battery assembly 20 can coincide, that is, the angle between the first preset assembly direction Z1 and the thickness direction of the battery assembly 20 is set to 0°. Based on this, the size of the outer shell assembly 10 in the second direction Y can be made smaller, further reducing the size of the movement module and improving the wearing comfort of the user.

[0042] 3, 4 and 5, the bottom wall of the battery assembly 20 abuts against the first bottom wall of the first accommodating space 121a. The first bottom wall of the first accommodating space 121a may refer to the inner wall of the second shell facing the user in the worn state. A certain amount of adhesive may be laid on the first bottom wall to bond the battery assembly 20. In some embodiments, under the premise that the battery assembly 20 abuts against the first bottom wall, the first limiting portion 1211 also abuts against the peripheral wall surface 21 of the battery assembly 20. Based on this, when the battery assembly 20 and the outer shell assembly 10 are fixedly connected by an adhesive such as glue, the first limiting portion 1211 can provide more bonding area between the outer shell assembly 10 and the battery assembly 20, thereby effectively improving the connection strength between the battery assembly 20 and the outer shell assembly 10 and preventing the battery assembly 20 from shaking inside the outer shell assembly 10.

[0043] In some embodiments, referring to Figures 3, 4 and 5, the first accommodating space 121a includes a second limiting portion 1212, and the second limiting portion 1212 is used to limit the movement of the battery assembly 20 along its radial direction, that is, the second limiting portion 1212 is used to limit the displacement of the battery assembly 20 relative to the outer shell assembly 10 in a direction perpendicular to the first preset assembly direction Z1. It can also be understood that the second limiting portion 1212 can increase the abutment points on the battery assembly 20 in a plane perpendicular to the first preset assembly direction Z1, thereby reducing the possibility of the battery assembly 20 moving relative to the outer shell assembly 10 in a plane perpendicular to the first preset assembly direction Z1, thereby effectively improving the stability of the connection between the battery assembly 20 and the outer shell assembly 10. In some embodiments, the second limiting portion 1212 can be set at a position opposite to the first limiting portion 1211, wherein the first limiting portion 1211 limits the rotation of the battery assembly 20 in the manner described in the above embodiments, and the second limiting portion 1212 abuts against the peripheral wall surface 21 of the battery assembly 20 at a position opposite to the first limiting portion 1211, thereby effectively limiting the movement of the battery assembly 20 relative to the outer shell assembly 10 in a direction perpendicular to the first preset assembly direction Z1.

[0044] Referring to Figures 3, 4 and 5, the first accommodating space 121a includes a first inner sidewall (not marked in the figure), which can be parallel to the inner wall of the shell in the thickness direction of the movement module. In some embodiments, the first inner sidewall is parallel to the first preset assembly direction Z1, wherein the second limiting portion 1212 and the first inner sidewall can be an integral structure, or a limiting protrusion provided on the first inner sidewall, or a combination of the two. Taking the second limiting portion 1212 and the first inner sidewall as an integral structure as an example, a portion of the first inner sidewall protrudes in a direction perpendicular to the first preset assembly direction Z1 to form the second limiting portion 1212, and the second limiting portion 1212 abuts against the peripheral wall surface 21 of the battery assembly 20, thereby limiting the movement of the battery assembly 20 relative to the shell assembly 10 in a direction perpendicular to the first preset assembly direction Z1. In some implementations, a limiting protrusion can be provided on the first inner sidewall as the second limiting portion 1212, which will not be described in detail herein.

[0045] In some embodiments, a positioning portion 1213 is provided in the first accommodating space 121a; the positioning portion 1213 and the first limiting portion 1211 are arranged at intervals, and the battery assembly 20 is provided with a positioning protrusion 22, which is used to be arranged between the positioning portion 1213 and the first limiting portion 1211 when the electromagnetic assembly 20 is assembled along the first preset assembly direction Z1, so that the positioning portion 1213 and the first limiting portion 1211 can assemble and position the battery assembly 20 when it is assembled in the first accommodating space 121a along the first preset assembly direction Z1.

[0046] Specifically, referring to Figures 4 and 5, the first accommodating space 121a is provided with a positioning portion 1213, and the battery assembly 20 is provided with a positioning protrusion 22. The positioning protrusion 22 can be provided on the peripheral wall surface 21 of the battery assembly 20. For example, when the battery assembly 20 is installed in the first accommodating space 121a of the housing assembly 10 along the first preset assembly direction Z1, a guide space along the first preset assembly direction Z1 is formed between the first limiting portion 1211 and the positioning portion 1213. The positioning protrusion 22 is placed in the above-mentioned guide space. In other words, the battery assembly 20 can be quickly installed into the first accommodating space 121a along the first preset assembly direction Z1 after being positioned by the positioning protrusion 22 and the guide space. Based on this, the installation efficiency of the battery assembly 20 can be effectively improved. In some embodiments, the positioning protrusion 22 can serve as a limiting protrusion, positioning the battery assembly 20 while limiting the movement of the battery assembly 20 in the housing assembly 10. Based on this configuration, the complexity of the battery assembly 20 is reduced and the production cost is reduced.

[0047] In some embodiments, the movement module 1 includes an electrode member 40 electrically connected to the battery assembly 20, and the electrode member 40 is disposed in the positioning portion 1213 and extends from the first accommodating space 121a to the outside of the outer shell assembly 10. Specifically, in one embodiment, the electrode member 40 is a component electrically connected to the battery assembly 20, and the positioning portion 1213 is provided with an electrode mounting portion that connects the first accommodating space 121a and the external space of the outer shell assembly 10, wherein the electrode member 40 is disposed in the electrode mounting portion and extends along the electrode mounting portion to the outside of the outer shell assembly 10. The battery assembly 20 can be electrically connected to the charging box of the external earphone 100 or other charging device through the electrode member 40, thereby realizing the charging function. In one embodiment, a mounting hole for mounting the electrode component can be provided on the positioning portion 1213, and a corresponding through hole can be provided on the outer shell component 10, so that after the electrode component 40 is installed in the mounting hole on the positioning portion 1213, it can directly extend out of the outer shell component 10 through the through hole and be electrically connected to a charging device such as a charging box. Based on this, the processing difficulty of the outer shell component 10 can be reduced and the cost can be reduced.

[0048] The number of positioning portions 1213 can be two. Referring to FIG. 5 , the two positioning portions 1213 are respectively provided on both sides of the first limiting portion 1211, and the positioning protrusion 22 can be provided between any positioning portion 1213 and the first limiting portion 1211. Furthermore, there can be two corresponding electrode members 40, and the two electrode members 40 are provided on the corresponding positioning portions 1213.

[0049] In some embodiments, the battery assembly 20 leads out wires for electrically connecting to other electronic components in the movement module 1, and the first accommodating space 121a includes a first bottom wall (not shown in the figure), which may refer to the inner wall surface of the second shell facing the user in the worn state. A lead groove 1214 is opened on the first bottom wall to accommodate the wires. Specifically, the first bottom wall is provided with an abutting portion that abuts against the bottom wall surface of the battery assembly 20, and a lead groove 1214 is also provided to accommodate the wires, wherein the lead groove 1214 is provided on the first bottom wall to reasonably arrange the wires, effectively reducing the space occupied by the wires, thereby effectively reducing the spatial volume of the outer shell assembly 10.

[0050] In some embodiments, the housing assembly 10 is provided with a partition wall 1215 that is used to separate the first accommodating space 121a from the second accommodating space 122a. The first limiting portion 1211 protrudes from the side of the partition wall 1215 that faces the first accommodating space 121a. Specifically, the partition wall 1215 separates the first accommodating space 121a from the second accommodating space 122a, thereby effectively separating the battery assembly 20 from the drive assembly 30, thereby preventing irreparable damage to the drive assembly 30 due to reasons such as battery fluid leakage from the battery assembly 20.

[0051] In some embodiments, the battery assembly 20 and the drive assembly 30 can be installed in the second shell 12. The second shell 12 is formed with an open end. A plurality of positioning grooves 1231 can be provided at the edge near the open end of the second shell 12. The first shell 11 is used to cover the second shell 12. A plurality of positioning posts 112 corresponding to the plurality of positioning grooves 1231 are provided near the edge of the first shell 11. At least a portion of the positioning posts 112 is embedded in the positioning grooves 1231. The notch of the positioning groove 1231 is provided with a first inclined wall 1232, which is used to guide the positioning posts 112 to fit into the positioning groove 1231.

[0052] Specifically, referring to Figures 3 to 6, the first housing 11 may be provided with a third accommodating chamber 111, and the second housing 12 may be provided with a first sub-accommodating chamber 121b and a second sub-accommodating chamber 122b separated by a partition wall 1215. After the first housing 11 and the second housing 12 are closed and connected, the third accommodating chamber 111 communicates with the first sub-accommodating chamber 121b and the second sub-accommodating chamber 122b, respectively, to form the aforementioned first accommodating space 121a and the second accommodating space 122a, respectively. The first accommodating space 121a and the second accommodating space 122a are collectively referred to as the accommodating space of the housing assembly 10. Based on the above method, the second shell 12 serves as the accommodating body for accommodating the battery assembly 20 and the drive assembly 30, the battery assembly 20 is accommodated in the first sub-accommodating cavity 121b, and the drive assembly 30 is accommodated in the second sub-accommodating cavity 122b. The first shell 11 serves as a cover body and is arranged on the second shell 12, thereby enclosing the battery assembly 20 and the drive assembly 30 in the first accommodating space 121a and the second accommodating space 122a respectively.

[0053] Furthermore, the first shell 11 and the second shell 12 are positioned and installed by the positioning column 112 and the positioning groove 1231, based on which the assembly efficiency of the first shell 11 and the second shell 12 can be effectively improved. In addition, since the second shell 12 serves as the main body for accommodating the battery assembly 20 and the drive assembly 30, it is not convenient to move the battery assembly 20 and the drive assembly 30 significantly after the battery assembly 20 and the drive assembly 30 are installed. Therefore, when the first shell 11 and the second shell 12 are assembled, the second shell 12 will remain as still as possible (for example, the second shell 12 equipped with the battery assembly 20 and the drive assembly 30 is fixed by the positioning base), and then the first shell 11 is placed on the second shell 12 from top to bottom along the direction of gravity to complete the assembly. The positioning groove 1231 is set on the second shell 12, and the positioning column 112 is set on the first shell 11. Based on this setting, when assembling the first shell 11 and the second shell 12, the positioning groove 1231 is located below the positioning column 112, and the assembler can more easily complete the alignment of the positioning column 112 and the positioning groove 1231. In addition, the notch of the positioning groove 1231 is provided with a first inclined wall 1232, and the first inclined wall 1232 provides a guide for the positioning column 112, which can effectively improve the smoothness of the positioning column 112 embedded in the positioning groove 1231, thereby effectively improving the assembly efficiency of the first shell 11 and the second shell 12, and there is no need to significantly adjust the second shell 12 equipped with the battery assembly 20 and the drive assembly 30, thereby effectively ensuring the overall assembly accuracy of the earphone 100 and ensuring the stability of the assembly of the battery assembly 20 and the drive assembly 30.

[0054] In some embodiments, the positioning post 112 can be configured to be molded along a first draft direction Z3 of the first housing 11. The movement module 1 includes a circuit board 50 housed within the accommodating space. The first draft direction Z3 can be perpendicular to the plane of the circuit board 50. In other words, the axis of the positioning post 112 is parallel to the first draft direction Z3, i.e., the axis of the positioning post 112 is perpendicular to the plane of the circuit board 50. Specifically, referring to Figures 3 and 6, the first draft direction Z3 is the direction in which the first housing 11 is drawn during the molding process. Configuring the molding direction of the positioning post 112 to be aligned with the draft direction of the first housing 11 effectively reduces the number of molding steps for the first housing 11, reduces the manufacturing complexity, and thereby effectively simplifies the structure of the first housing 11 and improves the molding efficiency of the first housing 11. Furthermore, the circuit board 50, which serves as a control circuit component for the earphone 100, is configured to be mounted between the first housing 11 and the second housing 12, i.e., within the accommodating space and spanning the first accommodating space 121a and the second accommodating space 122a. Among them, the circuit board 50 is fixedly connected to the first shell 11, and the plane where the circuit board 50 is located is perpendicular to the first demolding direction Z3. Based on this setting, the spatial volume occupied by the circuit board 50 in the second direction Y (wherein the first direction X, the first demolding direction Z3 and the second direction Y are located in the same plane and the first direction X and the second direction Y are perpendicular to each other) is effectively reduced, thereby effectively reducing the overall size of the shell assembly 10 along the second direction Y, thereby reducing the volume of the earphone 100 and improving the user's wearing comfort.

[0055] In some embodiments, the first housing 11 is provided with heat-staking posts 113, which are integrally formed with the first housing 11 along the first ejection direction Z3. The heat-staking posts 113 are used to secure the circuit board 50. Specifically, as shown in FIG3 , the circuit board 50 is fixedly connected to the first housing 11 via the heat-staking posts 113. Forming the heat-staking posts 113 along the first ejection direction Z3 effectively reduces the number of molding steps for the first housing 11, thereby effectively improving the molding efficiency of the first housing 11.

[0056] In some embodiments, the first preset assembly direction Z1 and the second preset assembly direction Z2 can be set at an acute angle; the angle between the first draft direction Z3 and the first preset assembly direction Z1 is in the range of 0° to 5°. Specifically, referring to the above description, the battery assembly 20 is accommodated in the first accommodating space 121a along the first preset assembly direction Z1, and the drive assembly 30 is accommodated in the second accommodating space 122a along the second preset assembly direction Z2. The relationship between the first preset assembly direction Z1 and the second preset assembly direction Z2 is as described above and will not be described in detail herein. In some embodiments, the first preset assembly direction Z1 can be parallel to the first draft direction Z3, that is, the angle between the first draft direction Z3 and the first preset assembly direction Z1 is 0°. Based on this, the overall draft structure of the housing assembly 10 conforms to the combination relationship of the preset assembly directions (first preset assembly direction Z1 and second preset assembly direction Z2) of the battery assembly 20 and the drive assembly 30, as described above, thereby effectively reducing the overall structural size of the housing assembly 10. The angle between the first demoulding direction Z3 and the first preset assembly direction Z1 may be in the range of 0° to 5°, which can also achieve the above-mentioned effect.

[0057] In some embodiments, the second shell 12 as described above is formed with a first sub-accommodating chamber 121b and a second sub-accommodating chamber 122b, the battery assembly 20 is accommodated in the first sub-accommodating chamber 121b, and the drive assembly 30 is accommodated in the second sub-accommodating chamber 122b; further, the circuit board 50 spans the first sub-accommodating chamber 121b and the second sub-accommodating chamber 122b. Based on this setting, the projection of the circuit board 50 along the normal direction of its main surface is set to simultaneously cover at least part of the drive assembly 30 and the battery assembly 20, which can fully utilize the space inside the earphone 100, making the earphone 100 compact in structure, which is conducive to reducing the volume of the earphone 100 and making it easier for users to wear.

[0058] Furthermore, the positioning groove 1231 can be configured to be formed along the second draft direction Z4 of the second shell 12, and the first draft direction Z3 and the second draft direction Z4 are arranged at an acute angle, and the acute angle range can be between 0° and 10°. Specifically, referring to Figures 3 and 6, the first preset assembly direction Z1 is parallel to the first draft direction Z3, and the second preset assembly direction Z2 is parallel to the second draft direction Z4. In other words, the second preset assembly direction Z2 coincides with the second draft direction Z4, based on which the molding process of the second shell 12 can be reduced. The first draft direction Z3 and the second draft direction Z4 are arranged at an acute angle, based on which the overall draft structure of the shell assembly 10 conforms to the combination relationship of the preset assembly directions (first preset assembly direction Z1 and second preset assembly direction Z2) of the battery assembly 20 and the drive assembly 30, as described above, thereby effectively reducing the overall structural size of the shell assembly 10.

[0059] In some embodiments, the groove wall of the positioning groove 1231 includes a first inclined wall surface 1232 that is inclined relative to the second draft direction Z4 and deviates toward the first draft direction Z3. The first inclined wall surface 1232 is used to guide the positioning post 112 into the positioning groove 1231. Specifically, referring to FIG6 , the positioning groove 1231 is provided with the aforementioned first inclined wall surface 1232. The first inclined wall surface 1232 is inclined relative to the second draft direction Z4 and deviates toward the first draft direction Z3. The inclination angle of the first inclined wall surface 1232 relative to the second draft direction Z4 can be the same as the angle between the first draft direction Z3 and the second draft direction Z4. Based on this, the first inclined wall surface 1232 can effectively guide the positioning post 112 into the positioning groove 1231.

[0060] In some embodiments, the second shell 12 is integrally formed, and the positioning groove 1231 can be formed at the edge of the open end of the second shell 12. Based on this, the assembly process of the second shell 12 can be reduced, and the assembly efficiency can be improved. In other embodiments, the second shell 12 includes a shell body 12A and a bracket 12B. The bracket 12B and the shell body 12A are separately formed and assembled. The shell body 12A is formed with a first sub-accommodation space 121b and a second sub-accommodation space 122b. The bracket 12B is assembled in the second sub-accommodation space 122b to support the assembly of the drive assembly 30. Part of the positioning groove 1231 is set on the shell body 12A, and the other part of the positioning groove 1231 is set on the bracket 12B, so as to facilitate flexible adjustment when the first shell 11 and the second shell are covered, thereby improving the accuracy of the covering of the first shell 11 and the second shell 12.

[0061] Furthermore, the first shell 11 is provided with a first support platform 114, and the positioning column 112 is provided on the first support platform 114 and extends outward from the bottom surface of the first support platform 114; the second shell 12 is provided with a second support platform 123, and the positioning groove 1231 is provided on the second support platform 123, and a notch is formed on the top surface of the second support platform 123; exemplarily, during the covering process of the first shell 11 and the second shell 12, when the positioning column 112 is partially embedded in the positioning groove 1231, there is a first gap L1 between the bottom surface of the first support platform 114 and the top surface of the second support platform 123, and at this time there is a second gap L2 between the edges of the first shell 11 and the second shell 12 covering each other; the minimum gap height of the first gap L1 is less than the minimum gap height of the second gap L2; wherein, the second gap L2 is used to accommodate fixing glue. By setting the minimum gap height of the first gap L1 to be smaller than the minimum gap height of the second gap L2, after the first shell 11 and the second shell 12 are installed in place, the second gap L2 still has sufficient height to accommodate an adhesive such as glue, thereby effectively ensuring an effective sealed connection between the edges of the first shell 11 and the second shell 12.

[0062] Optionally, the minimum gap distance of the first gap L1 is 0.02-0.07 mm, and the minimum gap distance of the second gap L2 is 0.08-0.12 mm.
