[0068] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0069] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0070] The motor housing 100 of this utility model embodiment is described below with reference to the accompanying drawings.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, the motor housing 100 is divided into a first housing 110 and a second housing 120. The second housing 120 is rotatably connected to the first housing 110, and a receiving cavity 130 for accommodating the electromagnetic component 200 is formed between the second housing 120 and the first housing 110.

[0072] In other words, the first housing 110 and the second housing 120 are rotatably connected. After the first housing 110 and the second housing 120 are connected in place, a receiving cavity 130 is formed between the first housing 110 and the second housing 120. The receiving cavity 130 is used to accommodate the electromagnetic component 200, so that the electromagnetic component 200 can be placed inside the motor housing 100. On the one hand, the motor housing 100 can be used to support the electromagnetic component 200, thereby improving the positional stability of the electromagnetic component 200 and ensuring the working performance of the electromagnetic component 200 to a certain extent. On the other hand, the motor housing 100 can also be used to protect the electromagnetic component 200, extend the service life of the electromagnetic component 200, and thus reduce the use cost of the electromagnetic component 200.

[0073] Meanwhile, by dividing the motor housing 100 into a first housing 110 and a second housing 120, the motor housing 100 is composed of two separate parts. In this way, when assembling the electromagnetic component 200, the electromagnetic component 200 can be first placed between the first housing 110 and the second housing 120, and then the first housing 110 and the second housing 120 can be connected. This reduces the assembly difficulty of the electromagnetic component 200, improves the assembly effect, and can also prevent the electromagnetic component 200 from impacting the motor housing 100 during the assembly process to a certain extent, thereby avoiding damage to the electromagnetic component 200, further extending the service life of the electromagnetic component 200, and ensuring the working performance of the electromagnetic component 200.

[0074] Furthermore, with the above settings, when the electromagnetic component 200 needs maintenance or repair, the motor housing 100 can be opened directly, thereby reducing the maintenance difficulty of the electromagnetic component 200 during use.

[0075] It is also worth noting that the second housing 120 is rotatably connected to the first housing 110 in this application. In this way, during the assembly process of the second housing 120 and the first housing 110, the second housing 120 and the first housing 110 can be rotatably connected first. After the connection is in place, at least one of the second housing 120 and the first housing 110 can be rotated to form the motor housing 100, thereby reducing the assembly difficulty of the motor housing 100.

[0076] In other words, the motor housing 100 of this application is divided into two parts (first housing 110 and second housing 120), and the two parts are rotatably connected. This allows the first housing 110 and the second housing 120 to rotate around the rotation connection point to open or close the motor housing 100, reducing the difficulty of opening and closing the motor housing 100.

[0077] When the first housing 110 and the second housing 120 rotate to fully open the interior of the motor housing 100, it facilitates the assembly and maintenance of the electromagnetic component 200, and also prevents the electromagnetic component 200 from colliding with the motor housing 100 during assembly to a certain extent. When the first housing 110 and the second housing 120 rotate to fully close the interior of the motor housing 100, the motor housing 100 can be used to support and protect the electromagnetic component 200.

[0078] As can be seen from the above structure, the motor housing 100 of this utility model embodiment separates itself into a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 are rotatably connected. This reduces the assembly difficulty of the motor housing 100, and also reduces the assembly and maintenance difficulty of the electromagnetic component 200. At the same time, it avoids collisions between the electromagnetic component 200 and the motor housing 100 during the assembly process, thus ensuring the working performance of the electromagnetic component 200.

[0079] Understandably, compared to the prior art, this application separates the motor housing 100 into a first housing 110 and a second housing 120, and rotatably connects the first housing 110 and the second housing 120 so that the first housing 110 and the second housing 120 can be opened, thereby reducing the assembly difficulty of the electromagnetic component 200 disposed in the receiving cavity 130. Furthermore, the rotatable connection of the first housing 110 and the second housing 120 also helps to reduce the assembly difficulty of the motor housing 100 itself, thereby enabling the electromagnetic component 200 to be effectively assembled inside the motor housing 100, and to a certain extent avoiding collisions between the electromagnetic component 200 and the motor housing 100 during the assembly process, thus ensuring the working performance of the electromagnetic component 200.

[0080] In some embodiments, the motor housing 100 is circumferentially divided into a first housing 110 and a second housing 120. That is, the motor housing 100 is divided into a first housing 110 and a second housing 120 in the circumferential direction, where the circumferential direction can be understood as the direction extending about the axial direction of the motor housing 100, and the axial direction can be understood as... Figure 1 The up-down direction shown in the figure allows the first housing 110 and the second housing 120 to be axially separated from the motor housing 100, reducing the assembly difficulty of the electromagnetic component 200, improving the assembly effect, and also preventing the electromagnetic component 200 from impacting the motor housing 100 during the assembly process to a certain extent, thereby avoiding damage to the electromagnetic component 200, further extending the service life of the electromagnetic component 200, and ensuring the working performance of the electromagnetic component 200.

[0081] It should be noted that the motor housing 100 of this application can be a square housing or a cylindrical housing. When the motor housing 100 is formed into a cylindrical housing, by arranging the first housing 110 and the second housing 120 along the circumference of the motor housing 100, the first housing 110 and the second housing 120 can be arranged opposite each other in the radial direction of the motor housing 100, so as to reduce the assembly difficulty of the motor housing 100 and reduce the difficulty of the electromagnetic component 200 and the motor housing 100 in mating.

[0082] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the electromagnetic component 200 includes a permanent magnet 220, which is disposed on the inner wall of the first housing 110 and the second housing 120, thereby enabling the electromagnetic component 200 to be disposed in the receiving cavity 130 of the motor housing 100. This facilitates the use of the motor housing 100 to support the electromagnetic component 200, improves the positional stability of the electromagnetic component 200, and also reduces the assembly difficulty between the electromagnetic component 200 and the motor housing 100.

[0083] In some embodiments, combined with Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first housing 110 has a first connecting portion 111 protruding therefrom, and the second housing 120 has a second connecting portion 121 protruding therefrom. The first connecting portion 111 and the second connecting portion 121 are rotatably connected. This means that the first housing 110 has the first connecting portion 111 protruding from the first housing 110, and the second housing 120 has the second connecting portion 121 protruding from the second housing 120. This facilitates the rotatable connection of the first connecting portion 111 and the second connecting portion 121, thereby reducing the difficulty of connecting the first connecting portion 111 and the second connecting portion 121.

[0084] Meanwhile, by rotatably connecting the first connecting part 111 and the second connecting part 121, the first housing 110 and the second housing 120 can be rotatably connected. In this way, during the assembly process of the second housing 120 and the first housing 110, the second housing 120 and the first housing 110 can be rotatably connected first. After the connection is in place, at least one of the second housing 120 and the first housing 110 can be rotated to form the motor housing 100, thereby reducing the assembly difficulty of the motor housing 100.

[0085] In some embodiments, combined with Figures 1-7 As shown, the first connecting portion 111 includes a plurality of first connecting lugs 1111, which are spaced apart. The second connecting portion 121 includes a plurality of second connecting lugs 1211, which are also spaced apart. The plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 are staggered. The motor housing 100 includes a connecting shaft 140 through which the plurality of first connecting lugs 1111 and the plurality of second connecting lugs 1211 pass. This allows the connecting shaft 140 to pass through the first connecting portion 111 and the second connecting portion 121, facilitating the rotational connection of the first connecting portion 111 and the second connecting portion 121 using the connecting shaft 140, thereby reducing the assembly difficulty of the motor housing 100.

[0086] It should be noted that the aforementioned staggered setting can be understood as... Figure 1 As shown in the left-right direction, the first connecting lug 1111 and the second connecting lug 1211 are not directly opposite each other, so that the multiple first connecting lugs 1111 and the multiple second connecting lugs 1211 are staggered. This way, after the first housing 110 and the second housing 120 are rotated and docked, the first connecting lugs 1111 and the second connecting lugs 1211 can be directly opposite each other in the front-back direction of the motor housing 100. The front-back direction here refers to... Figure 1The vertical and horizontal directions intersect, allowing the connecting shaft 140 to simultaneously pass through multiple first connecting lugs 1111 and multiple second connecting lugs 1211, so as to realize the connection of multiple first connecting lugs 1111 and multiple second connecting lugs 1211 by using the connecting shaft 140, that is, to realize the rotational connection of the first connecting part 111 and the second connecting part 121.

[0087] in, Figure 1 The left and right directions shown can also be understood as the docking directions of the first housing 110 and the second housing 120. That is, during the docking process of the first housing 110 and the second housing 120, multiple first connecting lugs 1111 and multiple second connecting lugs 1211 are staggered, so that after the docking process, the first connecting lugs 1111 and the second connecting lugs 1211 can be aligned in the front and rear direction of the motor housing 100.

[0088] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0089] In some embodiments, combined with Figures 1-7 As shown, the first connecting lug 1111 is provided with a first connecting hole 1112, and the second connecting lug 1211 is provided with a second connecting hole 1212. The connecting shaft 140 is used to pass through multiple first connecting holes 1112 and multiple second connecting holes 1212, so as to facilitate the rotational connection of the first connecting lug 1111 and the second connecting lug 1211 by using the connecting shaft 140, that is, to realize the rotational connection of the first connecting part 111 and the second connecting part 121.

[0090] In summary, the motor housing 100 of this application is divided into two parts along its circumference, and the first housing 110 and the second housing 120 are connected by the connecting shaft 140, the first connecting part 111 and the second connecting part 121. This allows the first housing 110 and the second housing 120 to rotate around the connecting shaft 140 to open or close the motor housing 100, thereby allowing the interior of the motor housing 100 to be fully opened. This is beneficial for the positioning, installation, fixing and maintenance of the electromagnetic components 200 inside the motor housing 100. Moreover, relative to the end opening of the motor housing 100, it can also prevent the electromagnetic components 200 from colliding with the motor housing 100 during the assembly process.

[0091] In some embodiments, such as Figure 2As shown, the ends of the first housing 110 and the second housing 120 are rotatably connected along the axial direction of the motor housing 100. That is, one axial end of the first housing 110 is rotatably connected to one axial end of the second housing 120, thereby achieving a rotatable fit between the first housing 110 and the second housing 120 and reducing the assembly difficulty of the first housing 110 and the second housing 120.

[0092] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first connecting part 111 is provided at one axial end of the first housing 110, and the second connecting part 121 is provided at one axial end of the second housing 120. In this way, after the first connecting part 111 and the second connecting part 121 are rotatably connected, the first housing 110 and the second housing 120 can be rotatably engaged, and the ends of the first housing 110 and the ends of the second housing 120 can be rotatably connected.

[0093] With the above configuration, during the assembly of the motor housing 100, one end of the first housing 110 and one end of the second housing 120 can be rotatably connected first. After the connection is in place, the electromagnetic component 200 is assembled between the first housing 110 and the second housing 120 (e.g., Figure 2 (As shown), then drive the other end of the first housing 110 and the other end of the second housing 120 to rotate toward each other, so as to achieve the mating connection between the first housing 110 and the second housing 120.

[0094] In other embodiments, such as Figure 3 As shown, the sidewalls of the first housing 110 and the second housing 120 are rotatably connected in the circumferential direction of the motor housing 100. That is, it is not limited to rotatably connecting one axial end of the first housing 110 and one axial end of the second housing 120; the sidewalls of the first housing 110 extending circumferentially along the motor housing 100 and the second housing 120 extending circumferentially along the motor housing 100 can also be rotatably connected. This also achieves a rotatable fit between the first housing 110 and the second housing 120, reducing the assembly difficulty of the first housing 110 and the second housing 120.

[0095] In some embodiments, such as Figure 3As shown, the first connecting part 111 is provided on the side wall of the first housing 110 extending circumferentially along the motor housing 100, and is located at one circumferential end of the side wall of the first housing 110. The second connecting part 121 is provided on the side wall of the second housing 120 extending circumferentially along the motor housing 100, and is located at one circumferential end of the side wall of the second housing 120. In this way, after the first connecting part 111 and the second connecting part 121 are rotatably connected, the first housing 110 and the second housing 120 can be rotatably engaged, and the side wall of the first housing 110 and the side wall of the second housing 120 can be rotatably connected.

[0096] With the above settings, as Figure 3 As shown, during the assembly of the motor housing 100, one end of the first housing 110 in the circumferential direction and one end of the second housing 120 in the circumferential direction can be rotatably connected first. After the connection is in place, the electromagnetic component 200 is assembled between the first housing 110 and the second housing 120. Then, the other end of the first housing 110 in the circumferential direction and the other end of the second housing 120 in the circumferential direction are driven to rotate toward each other to achieve the mating connection between the first housing 110 and the second housing 120.

[0097] In some embodiments, the first housing 110 and the second housing 120 are detachably coupled. That is, the first housing 110 and the second housing 120 are not only rotatably connected, but also detachably coupled, which enables the first housing 110 and the second housing 120 to be fixedly connected, making the relative positions of the first housing 110 and the second housing 120 stable, thereby ensuring the positional stability of the motor housing 100. This facilitates the use of the motor housing 100 to support and protect the electromagnetic component 200, thereby extending the service life of the electromagnetic component 200 and improving the positional stability of the electromagnetic component 200.

[0098] Meanwhile, by making the first housing 110 and the second housing 120 detachable, the difficulty of assembling and disassembling the first housing 110 and the second housing 120 can be reduced, thereby reducing the difficulty of assembling and disassembling the motor housing 100 and facilitating the maintenance of the electromagnetic components 200.

[0099] In some embodiments, combined with Figure 1 , Figure 4 and Figure 6As shown, one of the first housing 110 and the second housing 120 is provided with a third connecting portion 112, and the other is provided with a fourth connecting portion 122 opposite to the third connecting portion 112. A first fastener 150 connects the third connecting portion 112 and the fourth connecting portion 122 to make the first housing 110 and the second housing 120 detachable. This means that when the first housing 110 is provided with the third connecting portion 112, the second housing 120 is provided with the fourth connecting portion 122; and when the second housing 120 is provided with the third connecting portion 112, the first housing 110 is provided with the fourth connecting portion 122. By connecting the first fastener 150 to the third connecting portion 112 and the fourth connecting portion 122, a detachable connection between the first housing 110 and the second housing 120 can be achieved. This not only achieves a fixed connection between the first housing 110 and the second housing 120, but also stabilizes the relative positions of the first housing 110 and the second housing 120, thereby ensuring the positional stability of the motor housing 100 and reducing the assembly difficulty of the motor housing 100.

[0100] In some embodiments, combined with Figure 1 , Figure 4 and Figure 7 As shown, the third connecting part 112 is provided with a third connecting hole 1121, and the fourth connecting part 122 is provided with a fourth connecting hole 1221. The first fastener 150 connects the third connecting hole 1121 and the fourth connecting hole 1221, thereby realizing the fixed connection between the third connecting part 112 and the fourth connecting part 122.

[0101] Optionally, the first fastener 150 may be a fastening bolt, fastening screw, or rivet.

[0102] In summary, both the first housing 110 and the second housing 120 of this application are provided with connecting holes for connecting the first fastener 150, so as to install the first fastener 150 and thereby realize the fixed connection between the first housing 110 and the second housing 120.

[0103] In specific examples, combined Figure 1 , Figure 4 and Figure 7 As shown, the first housing 110 is provided with a third connecting part 112, and the second housing 120 is provided with a fourth connecting part 122 facing the third connecting part 112. The first fastener 150 connects the third connecting part 112 and the fourth connecting part 122 to realize the detachable engagement of the first housing 110 and the second housing 120.

[0104] Optionally, combined Figure 1 , Figure 4 and Figure 7As shown, the first housing 110 is provided with a plurality of third connecting portions 112, and the plurality of third connecting portions 112 are located at least on the two side walls of the first housing 110. The second housing 120 is provided with a plurality of fourth connecting portions 122 facing the third connecting portions 112. In this way, when the first fastener 150 connects the third connecting portions 112 and the fourth connecting portions 122, the different side walls of the first housing 110 and the second housing 120 can be detachably engaged, thereby improving the connection strength between the first housing 110 and the second housing 120, and thus stabilizing the relative position of the first housing 110 and the second housing 120.

[0105] In some embodiments, combined with Figure 1 , Figure 4 and Figure 7 As shown, the first housing 110 is provided with multiple third connecting parts 112 on its left and right sides and the top side, and the second housing 120 is provided with multiple fourth connecting parts 122 on its left and right sides and the top side, so that different side walls of the first housing 110 and the second housing 120 can be detachably connected, thereby improving the connection strength between the first housing 110 and the second housing 120.

[0106] In some embodiments, such as Figure 8 As shown, the motor housing 100 is provided with a clearance hole 160, which communicates with the receiving cavity 130. The clearance hole 160 is designed to allow the connecting rod 300 to pass through, and a cylindrical guide 170 is provided inside the clearance hole 160. By providing the clearance hole 160 to allow the connecting rod 300 to pass through and communicate with the receiving cavity 130, it is ensured that the connecting rod 300 can extend into the receiving cavity 130 through the clearance hole 160. By providing the cylindrical guide 170 inside the clearance hole 160, the guide 170 can guide the connecting rod 300 when it moves relative to the receiving cavity 130, ensuring the accuracy of the connecting rod's position during movement. It also prevents the connecting rod 300 from contacting the wall of the clearance hole 160 during movement, thus avoiding interference between the connecting rod 300 and the wall of the clearance hole 160, allowing the connecting rod 300 to move accurately relative to the receiving cavity 130.

[0107] It should be noted that, since the clearance hole 160 is formed on the motor housing 100, during the machining of the clearance hole 160, technical problems such as low smoothness of the hole wall and poor positional accuracy of the clearance hole 160 are likely to occur. If the connecting rod 300 is directly fitted with the clearance hole 160, interference between the connecting rod 300 and the clearance hole 160 during the movement is likely to occur. Therefore, this application provides a cylindrical guide 170 inside the clearance hole 160. In this way, while the guide 170 guides the connecting rod 300, it can also prevent the connecting rod 300 from interfering with the hole wall of the clearance hole 160 during the movement, so as to ensure the positional accuracy of the connecting rod 300 during the movement.

[0108] It should also be noted that the aforementioned connecting rod 300 can move or rotate relative to the receiving cavity 130.

[0109] In some embodiments, the guide member 170 is a guide bearing, which cooperates with the connecting rod 300 to guide the connecting rod 300, thereby ensuring the positional accuracy of the connecting rod 300 during movement.

[0110] Optionally, the guide 170 is detachably disposed within the clearance hole 160, which facilitates the separate machining of the guide 170 to ensure the structural accuracy of the guide 170 and thus ensure the guiding performance of the guide 170.

[0111] In some embodiments, such as Figure 9 and Figure 10 As shown, the outer periphery of the guide member 170 is provided with the protrusion 171, which is connected to the clearance hole 160 to realize the connection between the guide member 170 and the clearance hole 160. This facilitates the use of the guide member 170 to guide the connecting rod 300, and makes the structure of the guide member 170 simple and easy to install. At the same time, there is no need to add an additional installation and fixing structure to fix the guide member 170.

[0112] In some embodiments, such as Figure 8 and Figure 11 As shown, the connecting rod 300 is provided with an electromagnetic coil 210. When the connecting rod 300 is extended into the receiving cavity 130, the electromagnetic coil 210 can be placed in the receiving cavity 130 so that the electromagnetic coil 210 can cooperate with the permanent magnet 220, thereby ensuring the working performance of the motor 1000.

[0113] It should be noted that, since the motor housing 100 of this application is divided into a first housing 110 and a second housing 120 along its circumference, when the motor housing 100 is used in a linear motor, the electromagnetic coil 210 needs to be divided into two halves to be placed on the first housing 110 and the second housing 120, which would prevent the generation of magnetic field lines. Therefore, when the motor housing 100 is used in a linear motor, the electromagnetic coil 210 is placed on the connecting rod 300, and the permanent magnet 220 is placed on the first housing 110 and the second housing 120 and divided into two parts. When the motor housing 100 is used in a rotary motor, since the electromagnetic coil 210 has a different direction, the electromagnetic coil 210 can be placed on the first housing 110 and the second housing 120 and divided into two parts, or it can be placed on the connecting rod 300.

[0114] In some embodiments, combined with Figure 2 , Figure 4 and Figure 7 As shown, the first housing 110 is provided with a first clearance groove 113, and the second housing 120 is provided with a second clearance groove 123. The first clearance groove 113 and the second clearance groove 123 cooperate to define a clearance hole 160. In this way, while forming a clearance hole 160 that connects to the receiving cavity 130 on the motor housing 100, the forming difficulty of the clearance hole 160 and the fitting difficulty of the guide member 170, the connecting rod 300 and the clearance hole 160 are reduced, thereby improving the assembly efficiency of the motor housing 100.

[0115] At the same time, the above-mentioned arrangement also makes it easy to assemble the electromagnetic coil 210 on the connecting rod 300 into the receiving cavity 130.

[0116] In a specific example, during the assembly of the first housing 110 and the second housing 120, the first housing 110 and the second housing 120 can be rotatably connected first. After the rotatable connection, the electromagnetic coil 210 is assembled between the first housing 110 and the second housing 120. Then, the first housing 110 and the second housing 120 are driven to rotate relative to each other, so as to assemble the electromagnetic coil 210 in the receiving cavity 130 and make at least a portion of the connecting rod 300 connecting the electromagnetic coil 210 able to be provided in the clearance hole 160.

[0117] In addition, the above assembly method can also avoid contact between the electromagnetic coil 210 and the permanent magnet 220 during the assembly process to a certain extent, thereby preventing damage to the electromagnetic component 200 and ensuring the working performance of the electromagnetic component 200.

[0118] In summary, it can be understood that after the motor housing 100 is divided into a first housing 110 and a second housing 120 along its circumference, the dividing surface of the motor housing 100 is a plane through the axis of the guide member 170.

[0119] It should be noted that for cylindrical motor housings, this dividing surface can divide the cylindrical motor housing into two symmetrical parts; for motor housings of other shapes (such as square, pentagonal, etc.), this dividing surface can divide the motor housing into two symmetrical parts.

[0120] In other words, when the motor housing 100 is formed as a cylindrical motor housing, the first housing 110 and the second housing 120 are generally symmetrical in structure; when the motor housing 100 is formed as a motor housing of other shapes, the first housing 110 and the second housing 120 are generally asymmetrical in structure.

[0121] In some embodiments, such as Figure 2 , Figure 3 and Figure 8 As shown, a guide rod 400 is provided inside the receiving cavity 130. The guide rod 400 is used to guide the movement direction of the connecting rod 300 located inside the motor housing 100. This prevents the connecting rod 300 from deviating during movement, ensuring that the connecting rod 300 can move in a predetermined direction and guaranteeing the accuracy of the movement of the connecting rod 300. To a certain extent, this ensures that the relative axial distance between the motor housing 100 and the connecting rod 300 remains constant during their mutual movement.

[0122] With the above settings, when the suspension system with the motor housing 100 is applied to a vehicle, the wheels can move in a predetermined direction, ensuring the stability of the vehicle during driving.

[0123] In some embodiments, such as Figure 8 As shown, the connecting rod 300 has a guide hole 310 at one end located in the receiving cavity 130. The guide rod 400 is movably engaged with the guide hole 310 so as to guide the movement direction of the connecting rod 300 and ensure the accuracy of the movement of the connecting rod 300.

[0124] In some embodiments, such as Figure 2 , Figure 3 and Figure 8 As shown, the end of the guide rod 400 extends out of the first housing 110 and the second housing 120, and the end of the guide rod 400 is connected to the first housing 110 and the second housing 120. This achieves a fixed connection between the guide rod 400 and the motor housing 100, thereby facilitating the support of the guide rod 400 by the motor housing 100, improving the positional stability of the guide rod 400, ensuring the working performance of the guide rod 400, and facilitating the guidance of the moving direction of the connecting rod 300 by the guide rod 400.

[0125] Meanwhile, by extending the end of the guide rod 400 out of the first housing 110 and the second housing 120, the guide rod 400 and the motor housing 100 can be connected outside the motor housing 100, thereby reducing the difficulty of connecting the guide rod 400 and the motor housing 100, which means reducing the difficulty of fitting the guide rod 400.

[0126] In some embodiments, such as Figure 8 As shown, the motor housing 100 is provided with a clearance through hole 161, which communicates with the receiving cavity 130. The clearance through hole 161 is used to avoid the guide rod 400, so that the end of the guide rod 400 can extend out of the first housing 110 and the second housing 120 and connect with the first housing 110 and the second housing 120, thereby reducing the difficulty of connecting the guide rod 400 and the motor housing 100.

[0127] Optionally, combined Figure 5 and Figure 7 As shown, the first housing 110 is provided with a third clearance groove 114, and the second housing 120 is provided with a fourth clearance groove 124. The third clearance groove 114 and the fourth clearance groove 124 cooperate to define a clearance through hole 161. In this way, while forming a clearance through hole 161 connecting the receiving cavity 130 on the motor housing 100, the forming difficulty of the clearance through hole 161 and the fitting difficulty between the guide rod 400 and the clearance through hole 161 are reduced, thereby improving the assembly efficiency of the motor housing 100.

[0128] Optionally, such as Figure 8 and Figure 12 As shown, the guide rod 400 is provided with a guide protrusion 430, which is connected in conjunction with the clearance through hole 161 to realize the connection between the guide rod 400 and the clearance through hole 161, and to position the guide rod 400 to ensure the positional stability of the guide rod 400.

[0129] In some embodiments, combined with Figure 2 , Figure 4 , Figure 6 and Figure 8As shown, along the axial direction of the motor housing 100, the ends of the first housing 110 and the second housing 120 are rotatably connected. The first housing 110 has multiple spaced-apart first connecting lugs 1111, and the second housing 120 has multiple spaced-apart second connecting lugs 1211. The multiple first connecting lugs 1111 and the multiple second connecting lugs 1211 are staggered. The motor housing 100 includes a connecting shaft 140, through which the multiple first connecting lugs 1111, the multiple second connecting lugs 1211, and the end of the guide rod 400 pass. This means that when the ends of the first housing 110 and the second housing 120 are rotatably connected, the connecting shaft 140 can be inserted through the end of the guide rod 400 to achieve a fixed connection between the end of the guide rod 400 and the motor housing 100, reducing the difficulty of fitting the guide rod 400 to the motor housing 100, thereby facilitating the use of the motor housing 100 to support the guide rod 400 and improving the positional stability of the guide rod 400.

[0130] In some embodiments, combined with Figure 8 and Figure 12 As shown, a mounting bracket 410 is provided at the end of the guide rod 400. The mounting bracket 410 is provided with a mating hole 411. The connecting shaft 140 passes through the mating hole 411 to realize the mating connection between the connecting shaft 140 and the guide rod 400.

[0131] In summary, the first housing 110, the second housing 120, and the guide rod 400 of this application are connected together by a connecting shaft 140. The three can rotate relative to each other around the connecting shaft 140. During the specific assembly of the motor housing 100, the connecting shaft 140 is first passed sequentially through multiple first connecting lugs 1111, multiple second connecting lugs 1211, and the end of the guide rod 400 to achieve rotational engagement of the first housing 110, the second housing 120, and the guide rod 400. Then, the guide member 170 is sleeved on the connecting rod 300, and the connecting rod 300 is sleeved on the guide rod 400. Next, the guide rod 400, the guide member 170, and the connecting rod 300 are rotated around the connecting shaft 140, bringing them closer to the first housing 110 or... One of the second housings 120 is connected to ensure that the guide 170 fits in the third clearance groove 114 or the fourth clearance groove 124. Then, the other of the first housing 110 or the second housing 120 is controlled to rotate around the connecting shaft 140 so that the first housing 110 and the second housing 120 fit together. Finally, the first fastener 150 is used to connect the first housing 110 and the second housing 120 to achieve a fixed connection between the first housing 110 and the second housing 120. During the above connection process, the electromagnetic coil 210 on the connecting rod 300 can be completely prevented from contacting the permanent magnet 220 on the first housing 110 and the second housing 120, thereby avoiding damage to the electromagnetic component 200 and extending the service life of the electromagnetic component 200.

[0132] In other embodiments, such as Figure 3 As shown, in the circumferential direction of the motor housing 100, the sidewalls of the first housing 110 and the second housing 120 are rotatably connected. The end of the guide rod 400 extends to one side of the axial end of the first housing 110 and the second housing 120 and connects with them. This means that when the sidewalls of the first housing 110 and the second housing 120 are rotatably connected, the end of the guide rod 400 connects with the axial end of the first housing 110 and the second housing 120. This ensures that while the first housing 110 and the second housing 120 are rotatably connected, the guide rod 400 can also effectively cooperate with the connecting rod 300, facilitating the guidance of the connecting rod 300's movement direction.

[0133] In some embodiments, such as Figure 3 As shown, in the circumferential direction of the motor housing 100, the side walls of the first housing 110 and the second housing 120 are rotatably connected. The end of the guide rod 400 is provided with a mounting plate 420. The mounting plate 420 is provided with a fifth connecting hole 421. The first housing 110 and the second housing 120 are both provided with a sixth connecting hole 180 facing the fifth connecting hole 421. The second fastener connects the fifth connecting hole 421 and the sixth connecting hole 180 so that the guide rod 400 is fixedly connected to the first housing 110 and the second housing 120. This facilitates the use of the motor housing 100 to support the guide rod 400, improves the positional stability of the guide rod 400, and thus ensures the working performance of the guide rod 400.

[0134] Optionally, the second fastener may be a fastening bolt, fastening screw, or rivet.

[0135] In summary, the first housing 110 and the second housing 120 of this application are connected together by a connecting shaft 140, and the two can rotate relative to each other around the connecting shaft 140. During the specific assembly of the motor housing 100, the connecting shaft 140 is first passed sequentially through multiple first connecting lugs 1111 and multiple second connecting lugs 1211 to achieve a rotational fit between the first housing 110 and the second housing 120. Then, a connecting rod 300 is placed inside one of the first housing 110 and the second housing 120, and a guide member 170 is sleeved on the connecting rod 300 and the connecting rod 300 is sleeved on the guide rod 400. Next, the other housing of the first housing 110 and the second housing 120 is rotated around the connecting shaft 140, causing... It is close to one of the first housing 110 or the second housing 120, and ensures that the guide 170 fits in the third clearance groove 114 and the fourth clearance groove 124, so that the first housing 110 and the second housing 120 fit together. Finally, the first housing 110 and the second housing 120 are connected by the first fastener 150, and the guide rod 400 is connected by the second fastener to achieve a fixed connection between the first housing 110 and the second housing 120. In the above connection process, the electromagnetic coil 210 on the connecting rod 300 can be completely prevented from contacting the permanent magnet 220 on the first housing 110 and the second housing 120, thereby avoiding damage to the electromagnetic component 200 and extending the service life of the electromagnetic component 200.

[0136] In the description of this utility model, the features defined as "first", "second", "third", "fourth", "fifth" and "sixth" may explicitly or implicitly include one or more of the features, used to distinguish the descriptive features, without any order or importance.

[0137] The motor 1000 of this utility model is described below with reference to the accompanying drawings.

[0138] like Figure 1 , Figure 2 and Figure 3 As shown, a motor 1000 according to an embodiment of the present utility model includes: a motor housing 100 and a connecting rod 300.

[0139] Among them, such as Figure 1 , Figure 2 and Figure 3 As shown, the motor housing 100 is the aforementioned motor housing 100. The specific structure of the motor housing 100 will not be described in detail here. One of the electromagnetic coil 210 and the permanent magnet 220 of the electromagnetic component 200 is disposed in the motor housing 100.

[0140] Figure 2 and Figure 3As shown, the connecting rod 300 is movably engaged with the motor housing 100. The other of the electromagnetic coil 210 and permanent magnet 220 of the electromagnetic assembly 200 is located inside the motor housing 100 and connected to the connecting rod 300. This means that when the electromagnetic coil 210 is located inside the motor housing 100, the permanent magnet 220 is located inside the motor housing 100 and connected to the connecting rod 300; when the permanent magnet 220 is located inside the motor housing 100, the electromagnetic coil 210 is located inside the motor housing 100 and connected to the connecting rod 300. This allows the permanent magnet 220 and the electromagnetic coil 210 to cooperate with each other to control the relative movement of the connecting rod 300 and the motor housing 100, ensuring the working performance of the motor 1000.

[0141] It should be noted that, because the aforementioned motor housing 100 is simple and convenient to assemble, the motor 1000 of this utility model embodiment, by adopting the aforementioned motor housing 100, can effectively reduce the assembly and maintenance difficulty of the motor 1000, and to a certain extent avoid the electromagnetic component 200 from colliding with the motor housing 100 during assembly, as well as avoid the electromagnetic coil 210 and the permanent magnet 220 from colliding, thus ensuring the working performance of the electromagnetic component 200, which in turn ensures the working performance of the motor 1000 to a certain extent.

[0142] In some embodiments, the motor 1000 is a linear motor. This facilitates the application of the motor 1000 to the vehicle's suspension system, thereby ensuring the vehicle's performance.

[0143] In some embodiments, the linear motor is formed as a cylindrical linear motor. The cylindrical linear motor has a relatively closed structure, good sealing performance, and no unilateral magnetic pull, so as to ensure the working performance of the linear motor.

[0144] It should be noted that when the linear motor is formed into a cylindrical linear motor, the first housing 110 and the second housing 120 of the motor housing 100 are both formed into a semi-cylindrical shape. In this way, the first housing 110 and the second housing 120 can be combined to form a complete cylindrical motor housing.

[0145] In some embodiments, such as Figure 8 As shown, the linear motor is equipped with a damping spring 600. The damping spring 600 is used to provide some damping force and withstand some vibration impact to improve the working performance of the linear motor and thus ensure the comfort of the vehicle.

[0146] Optionally, such as Figure 8As shown, the linear motor includes a support base 500 and a lower tray 191. The support base 500 is connected to the side of the connecting rod 300 away from the receiving cavity 130, and the lower tray 191 is connected to the outer peripheral wall of the motor housing 100. A receiving space for a damping spring 600 is formed between the support base 500 and the lower tray 191. The damping spring 600 is placed in the receiving space so that the support base 500 and the lower tray 191 cooperate to fix the damping spring 600. In this way, when the linear motor is applied to the vehicle's suspension system, when the vehicle is excited by the road surface and the connecting rod 300 and the motor housing 100 move relative to each other, the damping spring 600 can be used to buffer and absorb vibrations. At the same time, the damping spring 600 can also play a certain damping role, improving the damping effect of the linear motor and thus improving the vehicle's comfort.

[0147] In some embodiments, such as Figure 8 As shown, the damping spring 600 is arranged between the support base 500 and the lower tray 191, with the upper end of the damping spring 600 abutting against the support base 500 and the lower end of the damping spring 600 abutting against the lower tray 191. In this way, during the relative movement of the connecting rod 300 and the motor housing 100, the damping spring 600 can be compressed or stretched to provide partial damping force and withstand part of the vibration impact, thereby improving the comfort of the vehicle.

[0148] In some embodiments, such as Figure 8 As shown, a bushing 700 is provided on the side of the connecting rod 300 away from the receiving cavity 130. The bushing 700 is connected to the support base 500. Buffer blocks 800 are provided on both opposite sides of the support base 500 and the lower tray 191. A damping spring 600 is located between the two buffer blocks 800.

[0149] The suspension system of this utility model is described below.

[0150] A suspension system according to an embodiment of the present utility model includes: a motor 1000, which is the aforementioned motor 1000 formed as a linear motor. The specific structure of the motor 1000 will not be described in detail here. One of the motor housing 100 and the connecting rod 300 is connected to the wheel end, and the other is connected to the vehicle body end.

[0151] It should be noted that, since the aforementioned linear motor 1000 is provided with a motor housing 100, and the motor housing 100 is simple and convenient to assemble, the suspension system of this utility model embodiment, by adopting the aforementioned motor housing 100, can effectively reduce the assembly and maintenance difficulty of the suspension system and ensure the working performance of the suspension system.

[0152] In a specific example, when a linear motor is applied to a vehicle's suspension system, it can be used to buffer the impact transmitted from the road surface, while also isolating noise from the road surface and tires to ensure vehicle comfort.

[0153] In some embodiments, the connecting rod 300 is adapted to be connected to the vehicle body end, and the motor housing 100 is adapted to be connected to the vehicle wheel end. During the process of the wheel moving up and down relative to the vehicle body, the connecting rod 300 and the motor housing 100 move relative to each other to buffer the impact transmitted by the road surface, and at the same time isolate the noise input from the road surface and tires to ensure the comfort of the vehicle.

[0154] Optionally, such as Figure 8 As shown, the connecting rod 300 is connected to a support base 500 on the side away from the receiving cavity 130. The support base 500 is suitable for installation onto the vehicle body. One of the first housing 110 and the second housing 120 is provided with a connecting arm 192. The motor housing 100 is connected to the vehicle wheel end through the connecting arm 192. This allows the linear motor to be installed onto the vehicle, thereby achieving a cooperative connection between the linear motor and the vehicle. This facilitates the use of the linear motor to buffer the impact from the road surface during vehicle operation, improving vehicle smoothness and thus ensuring vehicle comfort and enhancing the user experience.

[0155] Of course, in some other embodiments, the connecting rod 300 may be connected to the wheel end of the vehicle, and the motor housing 100 may be connected to the body end of the vehicle. This application does not impose any specific limitations.

[0156] The vehicle according to an embodiment of the present invention is described below.

[0157] A vehicle according to an embodiment of the present invention includes a suspension system, wherein the suspension system is the aforementioned suspension system, and the specific structure of the suspension system will not be described in detail here.

[0158] As can be seen from the above structure, the vehicle of this utility model embodiment, by adopting the aforementioned suspension system, can effectively reduce the assembly and maintenance difficulty of the vehicle, and facilitate the use of a linear motor to buffer the impact transmitted by the road surface, while isolating noise input from the road surface and tires to ensure the comfort of the vehicle.

[0159] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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 mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0160] The motor housing 100, motor 1000, suspension system, and other components of the vehicle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0161] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention.
