Since the end covers are typically thin-walled components with a high natural frequency, they are prone to resonance with the compressor's vibrations, leading to resonance noise and poor compressor quietness. Therefore, improvements are needed. Summary of the Invention

[0037] The compressor 100 according to a first aspect embodiment of the present application is described below with reference to the accompanying drawings.
[0038] As shown in FIG1, the compressor 100 according to the first aspect embodiment of the present application includes an end cover 10, a housing 20, a compression component, a drive motor, and an electronic control component. The end cover 10 is disposed on one side of the housing 20 and defines an electronic control cavity 20a between the end cover 10 and the housing 20. The end cover 10 is provided with a plurality of fixing parts 111, which are fixedly connected to the housing 20 so as to achieve a fixed connection between the end cover 10 and the housing 20 through the connection between the fixing parts 111 and the housing 20. The plurality of fixing parts 111 can improve the stability of the connection between the end cover 10 and the housing 20.
[0039] The compression component is located inside the housing 20 to compress the refrigerant. The drive motor is located inside the housing 20 and is used to drive the compression component. The electrical control component 30 is located inside the electrical control cavity 20a and is electrically connected to the drive motor to control the operating state of the drive motor. For example, the rotation, stopping, and speed of the drive motor can be controlled by the electrical control component 30 to control the refrigerant compression process.
[0040] The end cap 10 includes a cap body 1, a first reinforcing rib 2, and a second reinforcing rib 3. The cap body 1 defines a first region 1a and a second region 1b with different shapes. Both the first region 1a and the second region 1b are provided with a first reinforcing rib 2 and a second reinforcing rib 3. Each fixing part 111 is connected to at least one first reinforcing rib 2. The first reinforcing rib 2 of the first region 1a extends toward the center of the first region 1a, and the first reinforcing rib 2 of the second region 1b extends toward the center of the second region 1b. At least a portion of the first reinforcing rib 2 intersects with and is connected to the second reinforcing rib 3.
[0041] In other words, within the first region 1a, at least a portion of the first reinforcing rib 2 has its first end connected to the fixing part 111 located in the first region 1a, and its second end extends toward the center of the first region 1a, thereby enhancing the rigidity and strength of the thin-walled region at the center of the first region 1a through the first reinforcing rib 2 located in the first region 1a; within the second region 1b, at least a portion of the first reinforcing rib 2 has its first end connected to the fixing part 111 located in the second region 1b, and its second end extends toward the center of the second region 1b, thereby enhancing the rigidity and strength of the thin-walled region at the center of the second region 1b through the first reinforcing rib 2 located in the second region 1b. Furthermore, by providing a second reinforcing rib 3 connected to the first reinforcing rib 2, the reinforcing effect of the first reinforcing rib 2 on the thin-walled region can be significantly improved. Moreover, by providing a second reinforcing rib 3, the coverage area of the reinforcing rib structure on the cover body 1 can be significantly increased. For example, the second reinforcing rib 3 can be provided on the thin-walled region not covered by the first reinforcing rib 2, thereby improving the overall rigidity and strength of the cover body 1.
[0042] Therefore, by combining the first reinforcing rib 2 and the second reinforcing rib 3, the rigidity and strength of the central region of the first region 1a and the central region of the second region 1b can be improved, the natural frequency of the end cover 10 can be reduced to avoid resonance of the end cover 10 during the operation of the compressor 100, thereby reducing the vibration amplitude of the end cover 10 and reducing vibration noise.
[0043] According to the first aspect embodiment of the present application, the compressor 100, through the cooperation of the first reinforcing rib 2 and the second reinforcing rib 3, can improve the rigidity and strength of the central region of the first region 1a and the central region of the second region 1b, and can reduce the natural frequency of the end cover 10 to avoid resonance of the end cover 10 during the operation of the compressor 100, thereby reducing the vibration amplitude of the end cover 10 to reduce vibration noise.
[0044] Furthermore, it should be noted that by dividing the cover body 1 into a first region 1a and a second region 1b, the cover body 1 with a relatively irregular shape can be divided into a first region 1a and a second region 1b with a relatively regular shape. It is understood that the center of a structure with a regular shape is easier to locate. Therefore, the difficulty of locating the center region of the first region 1a and the second region 1b can be reduced, thereby reducing the difficulty of planning the extension direction of the second end of the first reinforcing rib 2, and thus reducing the design difficulty of the end cover 10.
[0045] In some embodiments, at least a portion of the fixing part 111 is correspondingly connected to a plurality of first reinforcing ribs 2, so that the force at the fixing part 111 can be transmitted and dispersed through the plurality of first reinforcing ribs 2, thereby improving the vibration reduction effect of the plurality of first reinforcing ribs 2 on the end cover 10. It should be noted that it may be that a portion of the fixing part 111 is correspondingly connected to a plurality of first reinforcing ribs 2, or all the fixing parts 111 may be correspondingly connected to a plurality of first reinforcing ribs 2, without any specific limitation.
[0046] According to some embodiments of this application, at least some of the second ends of the first reinforcing ribs 2 are connected, where the second end of the first reinforcing rib 2 refers to the end of the first reinforcing rib 2 that faces away from the fixing part 111. When the second ends of at least two first reinforcing ribs 2 are connected, the strength of each of the two connected first reinforcing ribs 2 can be significantly improved, thereby enhancing the reinforcing effect of the first reinforcing ribs 2 on the rigidity and strength of the cover body 1, and reducing the natural frequency of the end cover 10. Simultaneously, a continuous force transmission path can be formed between the two connected first reinforcing ribs 2, which is more conducive to the dispersion of force transmission and avoids vibration caused by stress concentration. It should be noted that the connection can be partial or complete; no specific limitation is made here.
[0047] According to some embodiments of this application, the number of first reinforcing ribs 2 in both the first region 1a and the second region 1b is not less than three. It is understood that if the number of first reinforcing ribs 2 is too small, the coverage area of the first reinforcing ribs 2 on the cover body 1 will be smaller, resulting in a poorer reinforcement effect on the cover body 1. Therefore, by controlling the number of first reinforcing ribs 2 to be not less than three, the coverage area of multiple first reinforcing ribs 2 on the cover body 1 can be better guaranteed, thus ensuring the reinforcement effect of multiple first reinforcing ribs 2 on the rigidity and strength of the cover body 1. The number of first reinforcing ribs 2 can be three, four, five, six, seven, eight, etc., and the number of first reinforcing ribs 2 can be flexibly adjusted according to needs; no specific limitation is made here.
[0048] According to some embodiments of this application, the number N1 of the first reinforcing ribs 2 and the number N2 of the second reinforcing ribs 3 satisfy: N1 - N2 ≥ 1. In other words, the number of second reinforcing ribs 3 is less than the number of first reinforcing ribs 2. Therefore, the number of second reinforcing ribs 3 can be better controlled to reduce the processing difficulty and production cost of the end cap 10, while avoiding the risk of interference between an excessive number of second reinforcing ribs 3 and the electronic control components 30.
[0049] According to some embodiments of this application, at least some adjacent first reinforcing ribs 2 are connected by a plurality of second reinforcing ribs 3. The more second reinforcing ribs 3 between adjacent first reinforcing ribs 2, the stronger the reinforcement effect on the portion of the cover body 1 located between adjacent first reinforcing ribs 2. Therefore, the rigidity and strength of the portion of the cover body 1 located between adjacent first reinforcing ribs 2 can be better enhanced. Simultaneously, multiple force transmission paths can be formed between adjacent first reinforcing ribs 2 through the plurality of second reinforcing ribs 3, which facilitates force transmission and dispersion, thereby reducing the vibration amplitude of the end cover 10 and reducing vibration noise.
[0050] According to some embodiments of this application, the cross-sections of the first reinforcing rib 2 and the second reinforcing rib 3 are circular, rectangular, or trapezoidal. That is, the cross-sections of the first reinforcing rib 2 and the second reinforcing rib 3 can be circular, as circular cross-sections distribute stress more evenly and are easier to process; the cross-sections of the first reinforcing rib 2 and the second reinforcing rib 3 can be rectangular, as rectangular cross-sections have higher bending and torsional stiffness; the cross-sections of the first reinforcing rib 2 and the second reinforcing rib 3 can be trapezoidal, such as having a structure that is narrower at the top and wider at the bottom. This increases the connection area between the bottom of the first reinforcing rib 2 and the cover body 1, thereby increasing the coverage area of the first reinforcing rib 2 and the second reinforcing rib 3 on the cover body 1, while reducing the size of the ends of the first reinforcing rib 2 and the second reinforcing rib 3 away from the cover body 1, to better avoid the electrical control component 30. It should be noted that this is only an example of some types of cross-sections of the first reinforcing rib 2 and the second reinforcing rib 3, and the cross-section types of the first reinforcing rib 2 and the second reinforcing rib 3 can be flexibly selected according to requirements.
[0051] According to some embodiments of this application, the cover body 1, the first reinforcing rib 2, and the second reinforcing rib 3 define a plurality of clearance grooves 4, the outer periphery of which forms a closed annular structure. After the end cover 10 is installed, an electronic control component 30 is arranged within the electronic control cavity 20a. The electronic control component 30 typically includes a circuit board and components disposed on the side of the circuit board facing the end cover 10. Therefore, the plurality of clearance grooves 4 formed on the end cover 10 can reduce the vibration noise of the end cover 10 through the first reinforcing rib 2 and the second reinforcing rib 3 while avoiding the components of the electronic control component 30, thereby ensuring that an appropriate electrical clearance is maintained between the end cover 10 and the electronic control component 30 to avoid the risk of interference between the end cover 10 and the electronic control component 30. Furthermore, the inner periphery of the clearance groove 4 is a complete and continuous integral, which can improve the structural stability of the clearance groove 4, thereby preventing deformation of the inner periphery of the clearance groove 4 and interference with components extending into the clearance groove 4.
[0052] The outer contour of the clearance groove 4 is circular, elliptical, or polygonal. It should be noted that the outer contour and depth of the clearance groove 4 can be flexibly adjusted according to the clearance requirements of the electronic control component 30, such as the shape of the components on the electronic control component 30, to ensure that there is an electrical clearance between the components on the electronic control component 30 and the end cover 10. This is only an example of the shape of the outer contour of some clearance grooves 4 for the purpose of understanding, and is not a limitation on the shape of the outer contour of the clearance groove 4.
[0053] According to some embodiments of this application, a third reinforcing rib 5 is provided within the clearance groove 4. Therefore, by providing the third reinforcing rib 5 within the clearance groove 4, the rigidity and strength of the thin-walled region within the clearance groove 4 can be effectively strengthened, thereby reducing the vibration amplitude of the thin-walled region within the clearance groove 4 and thus reducing the vibration noise of the end cap 10. Furthermore, one end of the third reinforcing rib 5 is connected to the inner peripheral wall of the clearance groove 4, and the other end of the third reinforcing rib 5 extends towards the center of the clearance groove 4. That is, the third reinforcing rib 5 extends along the direction from the inner peripheral wall of the clearance groove 4 to the center position, and the connection between the third reinforcing rib 5 and the inner peripheral wall of the clearance groove 4 can effectively improve the structural stability of the third reinforcing rib 5, thereby enhancing the strengthening effect of the third reinforcing rib 5 on the rigidity and strength of the inner bottom wall of the clearance groove 4. Simultaneously, a continuous force transmission path can be formed between the third reinforcing rib 5 and the inner peripheral wall of the clearance groove 4 to facilitate the distribution of force transmission. Therefore, the vibration amplitude of the portion of the cap body 1 located within the clearance groove 4 can be effectively reduced, thereby reducing the vibration noise of the end cap 10.
[0054] According to some embodiments of this application, a plurality of third reinforcing ribs 5 are provided within a single clearance groove 4, and the plurality of third reinforcing ribs 5 are arranged at intervals along the circumference of the clearance groove 4. It is understood that the more third reinforcing ribs 5 there are, the larger the coverage area within the clearance groove 4, and the stronger the reinforcement effect on the thin-walled region within the clearance groove 4. Therefore, by providing a plurality of third reinforcing ribs 5, the reinforcement effect of the third reinforcing ribs 5 on the cover body 1 can be improved. Furthermore, the circumferentially spaced arrangement of the plurality of third reinforcing ribs 5 in the clearance groove 4 allows the plurality of third reinforcing ribs 5 to effectively reinforce multiple different positions of the clearance groove 4 in the circumferential direction, thereby ensuring the uniformity of reinforcement of the thin-walled region within the clearance groove 4 by the plurality of third reinforcing ribs 5.
[0055] According to some embodiments of this application, the fixing part 111 located at the connection between the first region 1a and the second region 1b is an intermediate fixing part 111c, and at least one intermediate fixing part 111c is connected to multiple first reinforcing ribs 2. Therefore, the multiple first reinforcing ribs 2 connected to the intermediate fixing part 111c can effectively improve the rigidity and strength of the thin-walled region at the connection between the first region 1a and the second region 1b, thereby further reducing the natural frequency of the end cap 10 and avoiding vibration noise caused by resonance of the end cap 10.
[0056] According to some embodiments of this application, at least one intermediate fixing part 111c is correspondingly connected to two first reinforcing ribs 2 extending toward the first region 1a and the second region 1b respectively. That is, at least one first reinforcing rib 2 in the first region 1a and at least one first reinforcing rib 2 in the second region 1b are connected to the same intermediate fixing part 111c. Therefore, by connecting to the intermediate fixing part 111c and extending toward the center of the first region 1a, the rigidity and strength of the portion of the cover body 1 located between the intermediate fixing part 111c and the center of the first region 1a can be better enhanced. Similarly, by connecting to the intermediate fixing part 111c and extending toward the center of the second region 1b, the rigidity and strength of the portion of the cover body 1 located between the intermediate fixing part 111c and the center of the second region 1b can be better enhanced. This improves the rigidity and strength of the connection position between the first region 1a and the second region 1b, thereby reducing the vibration amplitude at the connection position and reducing the vibration noise of the end cap 10.
[0057] According to some embodiments of this application, in the first region 1a and the second region 1b, the ends of a plurality of first reinforcing ribs 2 are spaced apart, and any two adjacent ends of the first reinforcing ribs 2 are connected by corresponding second reinforcing ribs 3. Here, the end of the first reinforcing rib 2 refers to the end of the first reinforcing rib 2 that is away from the fixing part 111 in the extending direction. That is, the ends of the first reinforcing ribs 2 in the first region 1a are spaced apart and connected by a plurality of second reinforcing ribs 3 located at the center of the first region 1a, and the ends of the first reinforcing ribs 2 in the second region 1b are spaced apart and connected by a plurality of second reinforcing ribs 3 located at the center of the second region 1b. Through the connection of the first reinforcing ribs 2 and the second reinforcing ribs 3, the rigidity and strength of the central regions of the first region 1a and the second region 1b can be further enhanced, thereby reducing the vibration amplitude of the central regions of the first region 1a and the second region 1b.
[0058] According to some embodiments of this application, within the first region 1a, the ends of a plurality of first reinforcing ribs 2 and a plurality of second reinforcing ribs 3 connected to the ends of the first reinforcing ribs 2 together define a first central clearance groove 4a located at the center of the first region 1a. The outer periphery of the first central clearance groove 4a is a closed annular structure. That is, within the first region 1a, the ends of a plurality of first reinforcing ribs 2 and a plurality of second reinforcing ribs 3 constitute a closed annular rib structure, which has higher structural stability and can better enhance the reinforcement effect of the plurality of first reinforcing ribs 2 and second reinforcing ribs 3 on the central region of the first region 1a, thereby further reducing the natural frequency of the end cap 10.
[0059] According to some embodiments of this application, within the second region 1b, the ends of multiple first reinforcing ribs 2 and multiple second reinforcing ribs 3 connected to the ends of the first reinforcing ribs 2 together define a second central clearance groove 4b located at the center of the second region 1b. The outer periphery of the second central clearance groove 4b is a closed annular structure. That is, within the second region 1b, the ends of multiple first reinforcing ribs 2 and multiple second reinforcing ribs 3 form a closed annular rib structure, which has higher structural stability and can better enhance the reinforcement effect of multiple first reinforcing ribs 2 and second reinforcing ribs 3 on the central region of the second region 1b, thereby further reducing the natural frequency of the end cap 10.
[0060] According to some embodiments of this application, within the first region 1a, at least one second reinforcing rib 3 has its first end connected to one of the fixing parts 111 and its second end connected to a corresponding first reinforcing rib 2 connected to another fixing part 111. That is, within the first region 1a, at least one fixing part 111 is correspondingly connected to at least one first reinforcing rib 2 and at least one second reinforcing rib 3. This effectively increases the force distribution path, allowing the force at the fixing part 111 to be transmitted and dispersed simultaneously through the first reinforcing rib 2 and the second reinforcing rib 3, thereby reducing vibration noise of the end cap 10.
[0061] According to some embodiments of this application, a connecting flange 11 is formed on the outer peripheral edge of the cover body 1, and a fixing part 111 is formed on the connecting flange 11. In the second region 1b, at least one second reinforcing rib 3 is connected at both ends to the first reinforcing rib 2 and the connecting flange 11, respectively. As a result, the structural stability of the first reinforcing rib 2 and the second reinforcing rib 3 can be improved, thereby enhancing the reinforcing effect of the first reinforcing rib 2 and the second reinforcing rib 3.
[0062] According to some embodiments of this application, at least one first reinforcing rib 2 in the first region 1a and at least one first reinforcing rib 2 in the second region 1b are connected by a second reinforcing rib 3. Therefore, by connecting the first reinforcing rib 2 in the first region 1a and the first reinforcing rib 2 in the second region 1b with the second reinforcing rib 3, the rigidity and strength at the connection point between the first region 1a and the second region 1b can be better enhanced, thereby further reducing the natural frequency of the end cap 10.
[0063] According to some embodiments of this application, a boss 6 is provided on the side of the cover body 1 facing the electronic control component 30. The electronic control component 30 includes a circuit board and components disposed on the circuit board. The boss 6 is used to connect with the components on the circuit board. The connection between the boss 6 and the components on the circuit board can better maintain the relative position between the components on the circuit board and the end cover 10. It is understood that after the circuit board is placed in the electronic control cavity 20a and the end cover 10 is fixedly connected to the outer shell 20, the relative position between the end cover 10 and the outer shell 20 remains fixed. Therefore, the connection between the circuit board and the outer shell 20, and the connection between the boss 6 and the components, can better maintain the position of the components, thereby avoiding the risk of component wobbling and desoldering. Furthermore, the area on the cover body 1 where the boss 6 is arranged can enhance rigidity and strength through the boss 6, thereby reducing the natural frequency of the end cover 10 and preventing noise caused by resonance of the end cover 10.
[0064] According to some embodiments of this application, the height of the boss 6 is greater than the height of the first reinforcing rib 2 and the second reinforcing rib 3. For example, the boss 6, the first reinforcing rib 2, and the second reinforcing rib 3 are all disposed on the bottom surface of the cover body 1. In the vertical direction, the distance between the lower end of the boss 6 and the bottom surface of the cover body 1 is greater than the distance between the lower ends of the first reinforcing rib 2 and the second reinforcing rib 3 and the bottom surface of the cover body 1. That is, the lower end of the boss 6 is located below the lower ends of the first reinforcing rib 2 and the second reinforcing rib 3. Therefore, the first reinforcing rib 2 and the second reinforcing rib 3 can be prevented from interfering with the connection between the boss 6 and the components on the circuit board, thereby reducing the installation difficulty of the end cover 10.
[0065] According to some embodiments of this application, the boss 6 is cylindrical, cuboid, or cubic. It should be noted that the shape of the boss 6 can be flexibly adjusted according to the shape of the components connected to it on the circuit board and the avoidance requirements of other components. For example, if the component connected to the boss 6 is circular, the boss 6 can be cylindrical; if the component connected to the boss 6 is square, the boss 6 can be cuboid or cubic. This ensures that the boss 6 can better match the shape of the components, guaranteeing connection stability. Furthermore, when the boss 6 is used for heat dissipation of components, matching the shape of the boss 6 to the component increases the heat exchange area between the boss 6 and the component, thereby improving the heat dissipation effect. Furthermore, it is understandable that when the height of the boss 6 is relatively high, it is necessary to consider avoiding other components on the circuit board. Therefore, the boss 6 can make clearances according to the clearance requirements of the surrounding components, ensuring that there is an electrical clearance between the components on the circuit board that are not connected to the boss 6 and the boss 6. This is only an example of a part of the shape of the boss 6 for the purpose of understanding, and is not a limitation on the shape of the boss 6.
[0066] According to some embodiments of this application, both the boss 6 and the cover body 1 are metal parts. The surface of the boss 6 facing away from the cover body 1 is a connecting surface 61, and the connecting surface 61 is provided with a heat-conducting layer for contacting components. That is, one side of the heat-conducting layer is connected to the surface of the boss 6 facing away from the cover body 1, and the other side of the heat-conducting layer is in contact with the components on the circuit board. The heat generated by the components during operation can be transferred to the heat-conducting layer. It is understood that metal parts have good thermal conductivity, so the heat transferred to the heat-conducting layer can be transferred outward through the boss 6 and the cover body 1 to achieve rapid heat dissipation. That is, the end cover 10 can effectively dissipate heat from the components on the circuit board to avoid overheating damage to the components. In some embodiments, the heat-conducting layer is a flexible part. Therefore, while ensuring the thermal conductivity of the heat-conducting layer, it can better buffer the vibration transmission between the components on the circuit board and the boss 6 to reduce vibration noise. In a specific example, the heat-conducting layer is thermally conductive silicone.
[0067] It should be noted that the boss 6 and the cover body 1 can also be made of non-metallic thermally conductive materials, as long as the boss 6 and the cover body 1 have good thermal conductivity.
[0068] According to some embodiments of this application, the surface of the boss 6 facing away from the cover body 1 is a connecting surface 61. The connecting surface 61 is provided with a connecting post 62, which is used to insert and cooperate with components on the circuit board. Therefore, by inserting the connecting post 62 into the component, the degree of freedom of movement of the component relative to the connecting post 62 can be restricted, thereby improving the connection stability between the component and the boss 6. Specifically, the connecting hole of the component facing the boss 6 and the connecting post 62 is inserted into. During the installation of the end cover 10, the connecting post 62 is simply aligned with the connecting hole and inserted.
[0069] In some embodiments, multiple connecting posts 62 may be provided. In addition, the connecting posts 62 may be cylindrical, cuboid, or cubic, etc., and the connection method between the connecting posts 62 and the components may be clearance fit, interference fit, threaded connection, riveting, bonding, etc., without specific limitations.
[0070] According to some embodiments of this application, at least a portion of the first reinforcing rib 2 and at least a portion of the second reinforcing rib 3 are connected to the boss 6. That is, while the boss 6 is directly connected to the cover body 1, it is also connected to the cover body 1 through the first reinforcing rib 2 and the second reinforcing rib 3, which can effectively improve the structural stability of the boss 6, the first reinforcing rib 2, and the second reinforcing rib 3.
[0071] According to some embodiments of this application, the cover body 1 is provided with a plurality of protrusions 6. The plurality of protrusions 6 include at least a first protrusion 6a provided in the first region 1a and a second protrusion 6b provided in the second region 1b. The first protrusion 6a and the second protrusion 6b are connected by at least one second reinforcing rib 3. Thus, the first protrusion 6a, the second reinforcing rib 3 and the second protrusion 6b can be connected into a whole, with high structural strength and stability, which can improve the rigidity and strength of the cover body 1.
[0072] According to some embodiments of this application, the outer contour line of the first region 1a includes a connected arc-shaped contour line and a straight contour line, and the outer contour line of the second region 1b is rectangular, with the straight contour line coinciding with one side of the outer contour line of the second region 1b. That is, the second region 1b is connected to the edge of the straight contour line of the first region 1a, making the transition between the first region 1a and the second region 1b reasonable. The shape of the first region 1a is approximately the shape of a circle cut off at both ends of an arc, and the second region 1b is rectangular, which simplifies the shapes of the first region 1a and the second region 1b, reducing the difficulty of locating the center positions of the first region 1a and the second region 1b.
[0073] According to some embodiments of this application, the cover body 1 is integrally formed with the first reinforcing rib 2 and the second reinforcing rib 3. Therefore, this integrally formed structure not only ensures the structural and performance stability of the cover body 1 and the first reinforcing rib 2 and the second reinforcing rib 3, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates the need for assembly parts and connection processes used to connect the cover body 1 and the first reinforcing rib 2 and the second reinforcing rib 3, resulting in lower production costs and significantly improved assembly efficiency. This ensures reliable connection between the cover body 1 and the first reinforcing rib 2 and the second reinforcing rib 3. Moreover, the integrally formed structure has higher overall strength and stability, and a longer service life.
[0074] In some embodiments, the end cap 10 is a one-piece molded part.
[0075] According to some embodiments of this application, the number of fixing parts 111 is not less than six. The number of fixing parts 111 is directly proportional to the fixing strength of the end cap 10; that is, the more fixing parts 111 there are, the more fixing connection points the end cap 10 has after installation, and the more secure the installation of the end cap 10. Therefore, by controlling the number of fixing parts 111 to not less than six, the number of fixing connection points of the end cap 10 can be guaranteed, thus ensuring the secure installation of the end cap 10. For example, the number of fixing parts 111 can be six, seven, eight, nine, ten, eleven, etc.
[0076] According to some embodiments of this application, the cover body 1 is made of the same material as the first reinforcing rib 2 and the second reinforcing rib 3. Therefore, it is convenient to produce the end cover 10 using an integral molding process. In addition, the types of materials required for the production of the end cover 10 can be reduced, thereby reducing the difficulty of managing the materials used in the production of the end cover 10.
[0077] According to some embodiments of this application, at least a portion of the first reinforcing rib 2 and the second reinforcing rib 3 are made of a different material than the cover body 1. For example, the first reinforcing rib 2 may be made of the same material as the cover body 1, while the second reinforcing rib 3 may be made of a different material; the first reinforcing rib 2 may be made of a different material than the cover body 1, while the second reinforcing rib 3 may be made of the same material as the cover body 1; or both the first reinforcing rib 2 and the second reinforcing rib 3 may be made of a different material than the cover body 1, and so on. These are just a few examples. Therefore, the flexibility in selecting materials for the production end cover 10 can be significantly improved.
[0078] In some embodiments, the end cap 10 can be made of metal, non-metal, alloy, or organic material, etc. The first reinforcing rib 2 and the second reinforcing rib 3 can be formed by injection molding, welding, or processing, etc. The boss 6 can be formed by injection molding, welding, or processing, etc. The clearance groove 4 can be formed by injection molding, welding, or processing, etc.
[0079] According to some embodiments of this application, a connecting flange 11 is formed on the outer peripheral edge of the cover body 1, and a plurality of fixing parts 111 are formed on the connecting flange 11. The plurality of fixing parts 111 are arranged at intervals along the circumference of the cover body 1, and each fixing part 111 is provided with a mounting hole 112 to facilitate the fixing of the end cover 10 by means of threaded fasteners or the like. Specifically, the fixing part 111 located in the first region 1a is the first fixing part 111a, and the fixing part 111 located in the second region 1b is the second fixing part 111b. The first end of the first reinforcing rib 2 located in the first region 1a is connected to the first fixing part 111a, and the second end extends toward the center of the first region 1a. The first end of the first reinforcing rib 2 located in the second region 1b is connected to the second fixing part 111b, and the second end extends toward the center of the second region 1b.
[0080] According to some embodiments of this application, the side of the connecting flange 11 facing the housing 20 is formed as a sealing surface 113, and the sealing surface 113 is sealed to the housing 20. Therefore, the sealing effect between the end cover 10 and the housing 20 can be improved through the sealing connection between the sealing surface 113 and the housing 20, thereby preventing external dust, rainwater, etc. from entering the housing 20 through the gap between the end cover 10 and the housing 20, thus improving the protection effect of the end cover 10 and the housing 20 on the circuit board. It should be noted that the sealing surface 113 can be flat, knurled, etc., and no specific limitation is made here.
[0081] The sealing method between the sealing surface 113 and the outer shell 20 can be mechanical sealing, adhesive sealing, or friction welding. Specifically, a mechanical seal can be used to achieve a sealed connection between the end cap 10 and the outer shell 20. For example, a mechanical seal such as a sealing ring can be placed between the sealing surface 113 and the outer shell 20. The compression between the end cap 10 and the outer shell 20 deforms the sealing ring, filling the gap between them, thus achieving a sealed connection. Alternatively, an adhesive seal can be used. For example, sealant can be applied to the connection point between the sealing surface 113 and the outer shell 20, filling the gap and achieving a sealed connection. Finally, friction welding can be used to achieve a sealed connection between the sealing surface 113 and the outer shell 20. The relative friction between the sealing surface 113 and the outer shell 20 melts and then solidifies at the connection point, thus achieving a sealed connection.
