[0046] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0047] In this disclosure, unless otherwise indicated, directional terms such as "inner" and "outer" generally refer to the "inner" and "outer" relative to the corresponding component's own outline. Terms such as "first" and "second" are used to distinguish one element from another and do not have a sense of order or importance. Furthermore, in the following description, when referring to the drawings, unless otherwise indicated, identical reference numerals in different drawings represent identical or similar elements. The above definitions are intended only to explain and illustrate this disclosure and should not be construed as limiting the disclosure.

[0048] According to an exemplary embodiment provided by the present disclosure, with reference to Figures 1 to 5, a housing assembly for a motor is provided, which includes a housing 2 and a housing cover 5. The housing 2 is formed with an installation space and an opening 22, the opening 22 is connected to the installation space, and the housing cover 5 is covered in the opening 22 and is detachably connected to the housing 2.

[0049] Through the above technical solution, in the housing assembly for the motor provided in the present disclosure, the housing assembly includes a housing 2 and a housing cover 5, the housing 2 is formed with an installation space and has an opening 22 connected to the installation space, the housing cover 5 is used to cover the opening 22 and is detachably connected to the housing 2, so that when the motor needs to be assembled, it is only necessary to install other components constituting the motor (such as magnetic components 3, etc.) in the installation space through the opening 22 provided in the housing 2, and then fix the housing cover 5 to the housing 2, so as to achieve the purpose of facilitating the assembly of the motor and to improve the assembly efficiency of the motor.

[0050] In the housing assembly for the motor provided in the present disclosure, as an exemplary embodiment, as shown in reference figure 2, the housing assembly may include a positioning structure, and the positioning structure is arranged between the housing 2 and the housing cover 5. In this way, when it is necessary to fix the housing cover 5 to the housing 2, the positioning structure arranged between the housing 2 and the housing cover 5 can enable the staff to quickly find the installation position of the housing cover 5, thereby improving the assembly efficiency of the motor. At the same time, it can also ensure that the fitting clearance between the housing cover 5 and the housing 2 meets the design requirements, so as to effectively avoid the scrapping of parts caused by operational problems during the assembly process. In addition, the positioning structure can also ensure that the housing cover 5 remains in the installation position, avoiding displacement, misalignment, etc. during long-term use.

[0051] In the housing assembly for the motor provided in the present disclosure, as an exemplary embodiment, as shown in reference figure 3, the positioning structure may include a first positioning structure 230 and a second positioning structure 240. The first positioning structure 230 can be used to position the shell cover 5 on the shell 2 in the circumferential direction of the shell 2, and the second positioning structure 240 can be used to position the shell cover 5 on the shell 2 in the radial direction of the shell 2. In this way, the positioning of the shell cover 5 on the shell 2 can be achieved in multiple directions.

[0052] The first positioning structure 230 may be constructed in any suitable form to achieve the purpose of positioning the shell cover 5 on the shell 2 in the circumferential direction of the shell 2 , and the present disclosure does not impose any specific limitation on this.

[0053] As an exemplary embodiment, referring to FIG3 , the first positioning structure 230 may include a first positioning hole 23, a second positioning hole 51, and a positioning pin. The housing 2 may be provided with at least one first positioning hole 23, which may be arranged around the opening 22. The second positioning hole 51 is provided in a one-to-one correspondence with the first positioning hole 23, and the second positioning hole 51 is provided on the housing cover 5 and passes through the housing cover 5. The positioning pin is inserted into the first positioning hole 23 and the second positioning hole 51. On the one hand, the positioning pin can achieve the purpose of positioning the housing cover 5 on the housing 2 in the circumferential direction to avoid displacement or misalignment of the housing cover 5 in the circumferential direction during long-term use. On the other hand, the positioning pin can also locate the installation position of the housing cover 5 to prevent the occurrence of misinstallation. In addition, the specifications and quantity of the positioning pin and the corresponding first positioning hole 23 and second positioning hole 51 can be reasonably designed according to the actual mechanical strength requirements, such as 2, 3, or 4, etc., and the present disclosure does not impose specific restrictions on this.

[0054] In addition, in some other exemplary embodiments, the first positioning structure 230 may also include a positioning block and a positioning groove. One of the shell 2 and the shell cover 5 may be provided with a positioning block, and the other of the shell 2 and the shell cover 5 may be provided with a positioning groove. The positioning block is inserted into the positioning groove to complete the positioning between the shell 2 and the shell cover 5.

[0055] Similarly, the second positioning structure 240 can be constructed in any suitable form to achieve the purpose of positioning the housing cover 5 on the housing 2 in the radial direction of the housing 2, and the present disclosure does not impose any specific limitation on this.

[0056] As an exemplary embodiment, referring to what is shown in FIG3 , the shell cover 5 includes a cover body and a positioning flange 52. The second positioning structure 240 may include a positioning flange 52. The positioning flange 52 may be constructed in a ring shape and connected to one side of the cover body. The positioning flange 52 extends into the opening 22 and the outer peripheral wall of the positioning flange 52 is used to fit with the inner wall of the opening 22. On the one hand, the positioning flange 52 can achieve the purpose of positioning the shell cover 5 on the shell 2 in the radial direction of the shell 2. On the other hand, when the outer peripheral wall of the positioning flange 52 is interference fit with the inner wall of the shell 2, it can also play a certain pre-installation role for the shell cover 5. That is, when installing the shell cover 5, the first end of the shell cover 5 provided with the positioning flange 52 is extended into the shell 2 through the opening 22, and the shell cover 5 is temporarily connected to the shell 2 through the friction between the two. The shell cover 5 is rotated to adjust the installation position of the shell cover 5 relative to the shell 2, so that the first positioning hole 23 on the shell 2 is aligned one-to-one with the second positioning hole 51 on the shell cover 5, and then the shell 2 and the shell cover 5 are fixedly connected by fasteners (such as the connecting bolts 6 below).

[0057] In some embodiments thereof, the inner diameter of the positioning flange 52 may also be larger than the outer diameter of the shell 2 at the opening 22. In this way, when the shell cover 5 is installed, the positioning flange 52 can be mounted on the outside of the shell 2, that is, the inner peripheral wall of the positioning flange 52 is in contact with the outer wall of the shell 2, which can also achieve the purpose of positioning the shell cover 5 on the shell 2 in the radial direction of the shell 2. The present disclosure does not impose any specific restrictions on this.

[0058] In the housing assembly for the motor provided in the present disclosure, the housing cover 5 can be detachably connected to the housing 2 in any suitable manner, and the present disclosure does not impose any specific restrictions on this. As an exemplary embodiment, referring to Figures 3 and 4, the housing assembly can also include a plurality of connecting bolts 6, the housing 2 can be provided with a plurality of threaded holes 24 spaced around the opening 22, and the housing cover 5 can be provided with a plurality of through holes 53, the through holes 53 corresponding to the threaded holes 24 one by one, and the connecting bolts 6 pass through the corresponding through holes 53 and are threadedly connected to the corresponding threaded holes 24. In this way, whether the motor assembly requires fixing the housing cover 5 to the housing 2, or when a component in the housing 2 fails and the housing cover 5 needs to be disassembled for inspection or replacement, the bolt connection method can achieve rapid disassembly and assembly of the housing cover 5 and the housing 2. Furthermore, the bolt connection method can serve as a pre-installation mechanism. When installing the housing 2 and the housing cover 5, the housing cover 5 can be first connected to the housing 2 using the connecting bolts 6 without tightening them. The housing 2 can then be pushed and pulled to determine whether the motor rotor moves smoothly. After slightly adjusting the installation position of the housing cover 5, the connecting bolts 6 can be tightened to complete the fixation between the housing cover 5 and the housing 2. The number of connecting bolts 6 and the corresponding through holes 53 and threaded holes 24 can be reasonably designed based on actual mechanical strength requirements, such as 4, 6, or 8, and this disclosure does not impose any specific restrictions on this.

[0059] In some other embodiments, the shell cover 5 and the housing 2 can also be detachably connected by a snap connection to achieve both positioning and fixing, and the present disclosure does not impose any specific restrictions on this.

[0060] In the housing assembly for the motor provided in the present disclosure, as an exemplary embodiment, the housing 2 can have a first end and a second end relative to each other, and the first end and the second end can be respectively formed with an opening 22. The housing cover 5 can include a first housing cover 501 and a second housing cover 502. The first housing cover 501 and the second housing cover 502 can be respectively detachably connected to the first end and the second end. That is, the two ends of the housing 2 can be respectively detachably connected to the housing cover 5. During installation, the staff can select a suitable opening 22 according to actual conditions to install other components of the motor into the installation space, so as to improve the assembly efficiency of the motor.

[0061] On the basis of the above technical solution, referring to FIG2 and FIG5 , the present disclosure provides a motor, which includes the above-mentioned housing assembly for the motor. The housing assembly has all the technical features of the above-mentioned housing assembly, so they are not described here in detail.

[0062] In the motor provided in the present disclosure, as an exemplary embodiment, as shown in reference figure 2, the motor includes a stator assembly, the stator assembly includes a center rod 1, and the housing assembly is provided with a through hole 21, and the center rod 1 is slidably inserted into the through hole 21. In this way, the housing assembly can make reciprocating motion relative to the center rod 1 along the axial direction of the center rod 1, that is, the housing assembly can make reciprocating motion relative to the stator assembly.

[0063] The motor further comprises a mover assembly, which comprises a housing assembly and a guide rod 7. The center rod 1 may be provided with a mounting hole 11, and the guide rod 7 may be connected to the housing assembly and slidably inserted into the mounting hole 11. In this way, the guide rod 7 can move axially relative to the center rod 1 along the center rod 1. Since the guide rod 7 is connected to the shell cover 5 and the shell cover 5 is connected to the shell 2, the guide rod 7 can drive the shell cover 5 and the shell 2 to move axially relative to the center rod 1 along the center rod 1, that is, the mover assembly can make linear motion relative to the stator assembly, thereby realizing linear motion of the motor. In addition, by means of the guide rod 7 being slidably inserted into the mounting hole 11 of the center rod 1, the guide rod 7 is in sliding contact with the hole wall of the mounting hole 11 of the center rod 1 to guide the movement of the guide rod 7, the shell cover 5 and the shell 2, thereby preventing the shell 2 and the shell cover 5 from shaking during movement.

[0064] In the motor provided in the present disclosure, as an exemplary embodiment, as shown in reference figure 2, the motor can also include a first linear bearing 8 installed in the through hole 21, and the center rod 1 passes through the first linear bearing 8 and slides with the through hole 21 through the first linear bearing 8. On the one hand, the first linear bearing 8 can play a certain positioning role on the upper end of the center rod 1, and on the other hand, it can enable the upper end of the center rod 1 to meet the requirements of verticality and concentricity with the guide rod 7.

[0065] In the motor provided by the present disclosure, as an exemplary embodiment, as shown in FIG. 2 , the motor may further include a second linear bearing 9 mounted in the mounting hole 11. The guide rod 7 extends into the second linear bearing 9 and slides with the inner wall of the mounting hole 11 via the second linear bearing 9. The second linear bearing 9 not only serves to position the lower end of the center rod 1 but also ensures that the lower end of the center rod 1 meets the requirements for perpendicularity and concentricity with the guide rod 7.

[0066] It should be noted here that the first linear bearing 8 and the second linear bearing 9 in the present disclosure can both be sliding bearings. Sliding bearings have a larger contact area and adaptability, and therefore have a higher load capacity and can resist high impact loads and edge loads. Sliding bearings have excellent damping performance when running at high speed and low load, so as to improve the life of the sliding bearing itself and the two components in contact with the sliding bearing.

[0067] In the motor provided by the present disclosure, as an exemplary embodiment, the center rod 1, the housing 2, and the guide rod 7 are coaxially arranged. Since the guide rod 7 is connected to the housing cover 5, and the housing cover 5 is detachably connected to the housing 2, the center rod 1 can perform linear motion relative to the housing 2 and the guide rod 7 along the axial direction of the guide rod 7. In other words, the housing 2 and the guide rod 7 can perform linear motion relative to the center rod 1 along the axial direction of the guide rod 7, meeting the linear motion requirements of the motor. In addition, the guide rod 7 and the center rod 1 are coaxial with the housing 2, which can also avoid deflection, eccentricity, etc. during movement.

[0068] In the motor provided in the present disclosure, as an exemplary embodiment, referring to Figures 2 and 3, the housing assembly includes a housing cover 5 and a housing 2, the housing 2 has a first end and a second end relative to each other, the first end can be formed with an opening 22, the housing cover 5 includes a first housing cover 501, the first housing cover 501 can be arranged at the first end and cover the opening 22, the through hole 21 can be arranged in the housing 2 and located at the second end, the guide rod 7 can be connected to the first housing cover 501, in the present disclosure, the first end of the housing 2 can be regarded as the side facing the suspension body, that is, the first housing cover 501 is arranged on the side of the housing 2 facing the suspension body (refer to Figures 2 and 3), at this time, the through hole 21 is arranged in the housing 2 and located at the second end for the center rod 1 to pass through, the guide rod 7 is connected to the first housing cover 501 so as to be able to drive the first housing cover 501 and the housing 2 to move axially along the center rod 1 relative to the center rod 1.

As an exemplary embodiment, referring to FIG4 , the motor can further include a connecting arm 10, and the connecting arm 10 and the guide rod 7 can be respectively connected to opposite sides of the first shell cover 501, and the end of the connecting arm 10 away from the first shell cover 501 is formed with a connecting portion 101 for connecting to an external structure. In this way, when the motor needs to be installed, it is only necessary to fix the shell cover 5 in the desired position through the connecting arm 10. Since the shell cover 5 is fixed to the housing 2, the motor is fixed in the desired position.

[0070] Among them, the connecting portion 101 can be constructed in any suitable form according to actual installation requirements, and the present disclosure does not impose specific restrictions on this. As an exemplary embodiment, referring to what is shown in Figure 4, the connecting portion 101 can be constructed as a fork arm connected to the wheel end, and a mounting groove 1011 and a connecting hole 1012 are formed on the fork arm, wherein the mounting groove 1011 can be constructed as a U-shaped groove, and the two opposite groove walls of the U-shaped groove can be respectively provided with connecting holes 1012. In this way, when the motor is installed, the opening 22 of the U-shaped groove is pushed toward the external structure, so that the U-shaped groove is sleeved on the outside of the external structure, and the external structure is grasped in the U-shaped groove by passing fixing parts such as bolts through the connecting holes 1012, thereby fixing the motor to the external structure. In addition, the shape of the mounting groove 1011 can be designed to match the shape of the external structure during actual installation, and the present disclosure does not impose specific restrictions on this.

[0071] In the motor provided in the present disclosure, as an exemplary embodiment, the guide rod 7, the connecting arm 10 and the first shell cover 501 can be an integrated part to simplify the connection method between the various components of the motor, reduce the motor assembly process and assembly time, and improve the reliability of the motor structure. In addition, the one-piece molding implementation method also has the characteristics of strong integrity, high quality controllability and small error of the finished workpiece.

[0072] In the motor provided in the present disclosure, as an exemplary embodiment, as shown in Figure 6, the housing assembly may include a housing cover 5 and a housing 2, the housing 2 having a first end and a second end relative to each other, the second end may be formed with an opening 22, the housing cover 5 includes a second housing cover 502, the second housing cover 502 may be arranged at the second end and cover the opening 22, the through hole 21 may be arranged in the second housing cover 502, and the guide rod 7 may be connected to the housing 2. In the present disclosure, the second end of the housing 2 may be regarded as the side facing the vehicle body, that is, the second housing cover 502 is arranged on the side of the housing 2 facing the vehicle body (as shown in Figure 6). At this time, the through hole 21 is arranged in the second housing cover 502 and is located at the second end for the center rod 1 to pass through. The guide rod 7 is connected to the housing 2 so as to be able to drive the second housing cover 502 and the housing 2 to move axially relative to the center rod 1 along the center rod 1.

[0073] In the above case, the motor may further include a connecting arm 10, the connecting arm 10 being connected to the housing 2, and a connecting portion 101 for connecting to an external structure is formed at the end of the connecting arm 10 away from the housing 2, so that when the motor needs to be installed, the housing 2 only needs to be fixed in the required position by the connecting arm 10, and the motor is fixed in the required position. Among them, the connecting portion 101 can be constructed into any suitable form according to actual installation requirements, and the present disclosure does not impose specific restrictions on this. As an exemplary embodiment, as shown in reference to Figure 4, the connecting portion 101 is constructed as a fork arm connected to the wheel end, and the fork arm can have the same technical features as the fork arm connected to the first shell cover 501 mentioned above, so the present disclosure will not repeat them again.

Since the first shell cover 501 is fixed to the first end of the shell, and the second end of the shell 2 is fixed to the second shell cover 502, the shell assembly is fixed in the required position, that is, the motor is fixed in the required position. Among them, the connecting portion 101 can be constructed in any suitable form according to actual installation requirements, and the present disclosure does not impose specific restrictions on this. As an exemplary embodiment, referring to Figure 4, the connecting portion 101 can be constructed as a fork arm connected to the wheel end.

At this time, by controlling the direction of the power input by the external power supply, the repulsive or attractive force between the coil winding 4 and the magnetic part 3 can be controlled. Since the magnetic part 3 is connected to the shell 2, a magnetic field can be formed between the coil winding 4 and the magnetic part 3. It is fixed by pasting, and the repulsive or attractive force can push the magnetic part 3 to drive the shell 2 to move upward or downward along the axial direction of the center rod 1 relative to the center rod 1, so as to realize the linear reciprocating motion of the movable component relative to the stator component; by controlling the amount of power input by the external power supply, the amount of the repulsive or attractive force generated between the coil winding 4 and the magnetic part 3 can be controlled, and then the speed of the magnetic part 3 (or shell 2) moving upward or downward relative to the center rod 1 (or coil winding 4) can be controlled, that is, the speed of the movable component moving back and forth relative to the stator assembly is controlled, and finally the actual motion state required by the motor is achieved.
