In this way, the support seat 221 can be directly fixed and supported by the shell 210, and the interference fit can also improve the fixed and supporting effect of the shell 210 on the support seat 221, improve the position stability of the support seat 221, and further improve the position stability of the second guide piece 220, so as to achieve the purpose of centering the guide rod 222, which is conducive to improving the centering of the guide rod 222 when following the straight-line movement of the second assembly 200, thereby ensuring the coaxiality of the guide rod 222 and the guide cavity 111, increasing the stability of the relative movement of the first assembly 100 and the second assembly 200, and reducing the friction generated when the guide rod 222 moves relative to the guide cavity 111, thereby prolonging the service life of the guide rod 222 and the guide cavity 111.

[0055] In addition, ensuring the coaxiality of the guide rod 222 and the guide cavity 111 can also improve the guiding accuracy of the entire second guide piece 220, so that the movement of the second assembly 200 can be effectively ensured by the cooperation of the guide rod 222 and the guide cavity 111, and the second assembly 200 can also ensure good centering during movement, thereby reducing the movement resistance of the motor 1100 and improving the performance of the motor 1100.

[0056] Among them, the axial direction mentioned here can be understood as Figure 1 and Figure 2The first opening is arranged at one axial end of the shell 210, so that one end of the first guide 110 is arranged in the shell 210, and the first guide 110 is arranged in the shell 210, so that the first assembly 100 and the second assembly 200 are matched, the working performance of the motor 1100 is ensured to some extent, and the shell 210 can better protect the first guide 110 from external interference.

[0057] Meanwhile, the second opening is arranged at the other axial end of the shell 210, so that the second guide 220 is installed, the matching difficulty of the second guide 220 and the shell 210 is reduced, and the working performance of the second guide 220 is ensured.

[0058] In summary, the first opening and the second opening are arranged at the two axial ends of the shell 210, which can be understood as better installing, dismounting and matching parts.

[0059] It is worth noting that the second assembly 200 is split into the shell 210 and the second guide 220 in the application, and the support seat 221 of the second guide 220 is arranged in the second opening of the shell 210, so that the shell 210 and the second guide 220 are formed as separate parts, so that the shell 210 and the second guide 220 can be separately machined and formed during the processing of the second assembly 200, the forming difficulty of the shell 210 and the second guide 220 is reduced, so that the guide rod 222 of the second guide 220 can be movably matched in the guide cavity 111 of the first guide 110.

[0060] The guide rod 222 is movably matched in the guide cavity 111, so that the second assembly 200 is arranged in the first assembly 100, the second assembly 200 is guided to move by the guide rod 222 and the guide cavity 111, the deviation of the second assembly 200 during movement is avoided to some extent, the accuracy of the movement of the second assembly 200 is ensured, the second assembly 200 is prevented from rubbing with the first assembly 100 due to deviation, the motor 1100 is prevented from being damaged, the working efficiency of the motor 1100 is improved, the energy loss of the motor 1100 is reduced, and the working performance of the motor 1100 is ensured to some extent.

[0061] That is, by arranging the guide rod 222 and the guide cavity 111, the accuracy of the movement of the second assembly 200 is ensured, the service life of the motor 1100 is prolonged, and the working efficiency of the motor 1100 is improved.

[0062] From the above structure, the motor 1100 of the embodiment of the utility model, through the hollow setting of at least part first guide piece 110 form guide cavity 111, and guide rod 222 can be mobile cooperation in guide cavity 111, can realize the use guide rod 222 and guide cavity 111 cooperation guide second assembly 200 moves, avoid second assembly 200 in the moving process to a certain extent from deviating, guarantee second assembly 200 moves the accuracy, while avoiding second assembly 200 because of deviating and first assembly 100 mutual friction, in avoiding damaging motor 1100, still can avoid because of friction, lead to the thrust and tension of motor 1100 increase, thus improve the working efficiency of motor 1100, reduce the energy loss of motor 1100, to a certain extent guarantee the working performance of motor 1100.

[0063] At the same time, by interference fit of the outer peripheral wall of the support seat 221 and the inner peripheral wall of the shell 210, the shell 210 is directly used to fix and support the support seat 221, the fitting tolerance is reduced, and the interference fit can also improve the fixing and supporting effect of the shell 210 on the support seat 221, the guide rod 222 is centered, which is beneficial to improve the centering of the guide rod 222 when following the linear motion of the second assembly 200, so as to ensure the coaxiality of the guide rod 222 and the guide cavity 111, improve the motion accuracy of the second guide 220, and also improve the centering of the second assembly 200, so that the movement of the second assembly 200 can be effectively guided by cooperation of the guide rod 222 and the guide cavity 111, and the motor 1100 can stably output thrust and tension.

[0064] Compared with the prior art, it can be understood that the outer peripheral wall of the support seat 221 is interference fitted with the inner peripheral wall of the shell 210, the installation fitting tolerance is reduced, the size chain is shortened, the position accuracy of the guide rod 222 is improved, the centering of the guide rod 222 is improved, the centering of the guide rod 222 when following the linear motion of the second assembly 200 is improved, the coaxiality of the guide rod 222 and the guide cavity 111 is ensured, the movement of the second assembly 200 can be effectively guided by cooperation of the guide rod 222 and the guide cavity 111, the working performance of the second guide 220 is improved, the thrust and tension of the motor 1100 can be stably output, and the working efficiency of the motor 1100 is improved.

[0065] In some embodiments, the shell 210 is made of aluminum alloy, so that the shell 210 has good mechanical properties, excellent corrosion resistance and other characteristics, so that the shell 210 can better protect the internal components from damage from the outside, prolong the service life of the motor 1100.

[0066] In a specific example, the aluminum alloy can be processed by die casting process to obtain the shell 210, which reduces the forming difficulty of the shell 210.

[0067] In some embodiments, at least part of the shell 210 at the second opening periphery can be heated first during the assembly of the support base 221 and the shell 210. After the shell 210 is heated and deformed, the support base 221 is assembled to the second opening. After the shell 210 cools down, the interference fit between the outer peripheral wall of the support base 221 and the inner peripheral wall of the shell 210 is achieved, which reduces the assembly difficulty of the support base 221 and the shell 210 and ensures the assembly quality.

[0068] In some embodiments, as shown in Figure 2 The first assembly 100 further includes a coil winding 120 wound around at least part of the outer periphery of the first guide 110 and located in the shell 210, and the second assembly 200 further includes a magnetic steel 240 arranged in the shell 210. The coil winding 120 and the magnetic steel 240 cooperate to achieve the coupling fit of the first assembly 100 and the second assembly 200, so that the second assembly 200 can move reciprocally, which to some extent ensures the working performance of the motor 1100.

[0069] In a specific example, the coil winding 120 is energized, and the coil winding 120 generates a magnetic field after being energized to make the magnetic steel 240 move linearly. At this time, the coil winding 120 and the magnetic steel 240 cooperate to achieve the coupling fit of the first assembly 100 and the second assembly 200 (the cooperation of the coil winding 120 and the magnetic steel 240 to achieve the working principle of the motor 1100 belongs to the prior art, and is not described here), so that the second assembly 200 can move reciprocally to achieve the purpose of vibration reduction.

[0070] It should be noted that by winding the coil winding 120 around at least part of the outer periphery of the first guide 110, the coil winding 120 can be supported by the first guide 110, the position stability of the coil winding 120 is improved, and the working performance of the coil winding 120 is ensured to some extent.

[0071] At the same time, by arranging the magnetic steel 240 in the shell 210, the shell 210 can support and protect the magnetic steel 240 while ensuring that the coil winding 120 and the magnetic steel 240 can cooperate to achieve the coupling fit of the first assembly 100 and the second assembly 200, which improves the position stability of the magnetic steel 240 and prolongs the service life of the magnetic steel 240.

[0072] In some embodiments, the magnetic steel 240 is a rare earth permanent magnet material. In order to generate a stable magnetic field.

[0073] In a specific example, the motor 1100 is a suspension motor. When the motor 1100 is arranged in a vehicle, it can effectively achieve the effect of buffering and absorbing vibration.

[0074] In a specific example, the first component 100 is a stator component, the second component 200 is a rotor component, and the first guide 110 is formed as a stator core shaft 110.

[0075] In some embodiments, in the axial direction of the motor 1100, the extension length of the outer peripheral wall of the support seat 221 ranges from 4 mm to 10 mm. Here, the extension length of the outer peripheral wall of the support seat 221 can be understood as the length of the outer peripheral wall of the support seat 221 in the axial direction of the motor 1100, as shown by L1 in FIG. 11. Figure 3 When the extension length of the outer peripheral wall of the support seat 221 is too short, the fitting strength of the support seat 221 and the shell 210 is reduced, and when the extension length of the outer peripheral wall of the support seat 221 is too long, the space area occupied by the support seat 221 inside the motor 1100 is increased, affecting the installation of the magnetic steel 240, which is not conducive to the installation and arrangement of the internal space of the motor 1100.

[0076] In summary, the extension length of the outer peripheral wall of the support seat 221 is set to range from 4 mm to 10 mm, which not only ensures that the outer peripheral wall of the support seat 221 can effectively fit with the inner peripheral wall of the shell 210, but also avoids the support seat 221 from occupying too much space area inside the motor 1100, facilitating the installation of the magnetic steel 240, thereby reducing the assembly difficulty of the motor 1100.

[0077] Specifically, the extension length of the outer peripheral wall of the support seat 221 is 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm, etc.

[0078] In some embodiments, the support seat 221 and the guide rod 222 are formed as an integral piece. In this way, the support seat 221 and the guide rod 222 can be made by an integral molding process, reducing the molding difficulty of the support seat 221 and the guide rod 222, and also saving the fitting connection of the support seat 221 and the guide rod 222, ensuring the connection quality of the support seat 221 and the guide rod 222, which is conducive to constituting the second guide 220, reducing the molding difficulty of the second guide 220, and improving the structural strength of the second guide 220, to a certain extent, ensuring the working performance of the second guide 220.

[0079] In some embodiments, during the production and processing of the second guide 220, a grinding molding process can be used to form the support seat 221 and the guide rod 222 as an integral piece.

[0080] The grinding forming process can also make the coaxiality size of the outer circumferential surface of the guide rod 222 and the outer circumferential wall of the support seat 221 very small, so that the positioning fitting surface of the outer circumferential surface of the guide rod 222 and the outer circumferential wall of the support seat 221 can be formed as a concentric structure, so that when the support seat 221 is positioned, the guide rod 222 can be centered, which is beneficial to improve the centering of the second assembly 200, to a certain extent, avoid the deviation of the second assembly 200 relative to the first assembly 100 when moving, thereby reducing the movement resistance of the motor 1100 and improving the performance of the motor 1100.

[0081] Of course, in other embodiments, the support seat 221 and the guide rod 222 can also be formed as separate parts. That is, the support seat 221 and the guide rod 222 are separately machined and formed, and then the support seat 221 and the guide rod 222 are connected (such as by welding, bonding, etc.) after the support seat 221 and the guide rod 222 are machined and formed. It can also constitute the second guide 220.

[0082] In some embodiments, as shown in Figure 4 The support seat 221 and the guide rod 222 are connected through the circular arc segment 223. It can be understood that the connection between the support seat 221 and the guide rod 222 is transitioned through the circular arc segment 223, so that the connection between the support seat 221 and the guide rod 222 can effectively resist deformation, reduce stress concentration, to a certain extent, avoid the connection between the support seat 221 and the guide rod 222 from breaking, prolong the service life of the second guide 220, and improve the structural strength of the second guide 220, to a certain extent, ensure the working performance of the second guide 220.

[0083] In some embodiments, in combination with Figure 2 and Figure 3 The motor 1100 also includes a buffer 300, which is sleeved on the outer periphery of the second guide 220 and located between the first guide 110 and the support seat 221. The buffer 300 is used to buffer the relative displacement of the first assembly 100 and the second assembly 200. It achieves the purpose of limiting the maximum movement position of the second assembly 200, and can effectively reduce the impact force when the second assembly 200 contacts the first assembly 100, so as to avoid rigid contact between the first assembly 100 and the second assembly 200, thereby prolonging the service life of the motor 1100.

[0084] In some embodiments, the buffer 300 can be made of rubber, silicone or other materials to ensure the buffering performance of the buffer 300.

[0085] In some embodiments, in combination with Figure 3 and Figure 4As shown, the support base 221 is provided with a first mounting groove 224 on the side facing the first guide 110, and at least part of the buffer 300 is arranged in the first mounting groove 224. This is conducive to reducing the axial height of the buffer 300 relative to the second guide 220, avoiding excessive reduction of the relative position of the second assembly 200 and the first assembly 100 due to the arrangement of the buffer 300, thereby increasing the movement stroke of the motor 1100 and to some extent ensuring the working performance of the motor 1100.

[0086] That is, by arranging the first mounting groove 224 and arranging at least part of the buffer 300 in the first mounting groove 224, the impact force when the second assembly 200 contacts the first assembly 100 is reduced by the buffer 300, and the movement stroke of the motor 1100 is also increased.

[0087] In some embodiments, the groove depth of the first mounting groove 224 is in the range of 3mm-6mm. When the groove depth of the first mounting groove 224 is too shallow, it is not conducive to increasing the movement stroke of the motor 1100; when the groove depth of the first mounting groove 224 is too deep, it is easy to reduce the thickness of the support base 221 and reduce the structural strength of the support base 221.

[0088] In summary, the groove depth of the first mounting groove 224 is set to be in the range of 3mm-6mm, so that at least part of the buffer 300 can be arranged in the first mounting groove 224, the movement stroke of the motor 1100 is increased, and the support base 221 has a certain thickness, the structural strength of the support base 221 is improved, and to some extent, the working performance of the support base 221 is ensured.

[0089] Specifically, the groove depth of the first mounting groove 224 is 3mm, 4mm, 5mm or 6mm, etc.

[0090] In some embodiments, as shown, Figure 2 As shown, the first guide 110 and the inner circumferential wall of the first opening are provided with a first guide bearing 400. The first guide bearing 400 is used to guide the movement of the second assembly 200, so as to avoid the deviation of the second assembly 200 during movement and ensure the accuracy of the movement of the second assembly 200.

[0091] At the same time, the first guide bearing 400 can also reduce the wear between the first assembly 100 and the second assembly 200, prolong the service life of the motor 1100, reduce the movement resistance of the motor 1100, and improve the performance of the motor 1100.

[0092] In some embodiments, the first guide bearing 400 is arranged in the first opening and fixedly connected with the shell 210, and the first guide bearing 400 is in sliding fit with the first guide 110, so as to arrange the first guide bearing 400 between the first guide 110 and the inner circumferential wall of the first opening, facilitate supporting the first guide bearing 400 by the shell 210, improve the position stability of the first guide bearing 400, and ensure the working performance of the first guide bearing 400 to a certain extent.

[0093] In some embodiments, the first guide bearing 400 is arranged in the first opening and fixedly connected with the shell 210, and the first guide bearing 400 is in sliding fit with the first guide 110, so as to arrange the first guide bearing 400 between the first guide 110 and the inner circumferential wall of the first opening, facilitate supporting the first guide bearing 400 by the shell 210, improve the position stability of the first guide bearing 400, and ensure the working performance of the first guide bearing 400 to a certain extent.
