Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a positioning cover, a filter, and an automobile. Background Technology

[0002] A generator controller is an independent motor controller used in the engine compartment of a car to control the start, stop, and operation of the motor. The generator controller includes a filter to remove stray signals and prevent interference during signal transmission. The filter is equipped with copper busbars for charging and discharging. The temperature of the copper busbars rises when there is excessive current, therefore, heat dissipation is necessary.

[0003] Currently, thermal pads are generally used to dissipate heat from copper busbars. The thermal pads are directly attached to the copper busbars to conduct heat and dissipate heat. However, the thermal pads are prone to displacement when directly attached to the copper busbars, which affects the heat dissipation effect. Moreover, the displacement of the thermal pads can expose the copper busbars, which poses a risk of creepage or leakage. Utility Model Content

[0039] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0040] As described in the background section, when the filter in the generator controller is energized, the copper busbars will rapidly heat up due to prolonged overload and high current. To prevent the copper busbars from burning out, it is necessary to dissipate and cool them down. Since the filter is in a relatively sealed space, liquid cooling contact heat dissipation is often used for cooling the copper busbars. Currently, the most common method is to use thermal pads, which are directly attached to the copper busbars for heat exchange. However, due to the high temperature of the copper busbars, ordinary adhesives cannot firmly bond the thermal pads to them, causing them to shift. This displacement affects the heat dissipation effect and can also expose parts of the covered copper busbars, posing a risk of creepage or leakage.

[0041] Based on the above problems, embodiments of this utility model provide a positioning cover, a filter, and a car, which can solve the above problems, and will be described in detail below.

[0042] Please refer to Figures 1 to 3 The positioning cover 1 includes a cover body 10 and multiple positioning connecting parts 11. The cover body 10 is provided with multiple through holes 101, which all penetrate the inner wall surface 102 and the outer wall surface 103 of the cover body 10. The inner wall surface 102 of the cover body 10 can be used to set the heat-conducting pad 4. The multiple positioning connecting parts 11 are arranged around the circumference of the cover body 10 and are all connected to the cover body 10. The positioning connecting parts 11 are used to press the heat-conducting pad 4 tightly when the cover body 10 is connected to the filter housing 2.

[0043] In this embodiment, the cover 10 is a rectangular plate, and the two ends of the through hole 101 penetrate the inner wall surface 102 and the outer wall surface 103 of the rectangular plate, respectively. There are multiple through holes 101, which can be interconnected or spaced apart. In this embodiment, two through holes 101 are shown, which are spaced apart and respectively arranged along the long side of the rectangular plate. In addition, the shape of the through hole 101 can also be in various forms, such as a round hole, a rectangular hole, or a long strip hole. The shape of the through hole 101 is not limited here.

[0044] The positioning connecting part 11 is fixed to the cover 10 to ensure a stable connection. Multiple positioning connecting parts 11 are provided along the edge of the rectangular plate. These multiple positioning connecting parts 11 can be arranged at equal intervals or non-equal intervals. In this embodiment, there are two positioning connecting parts 11, respectively located on both sides of the short side of the rectangular plate and arranged symmetrically. Here, the short side refers to the wide side of the rectangular plate. In other embodiments, there can be four or six positioning connecting parts 11. Four positioning connecting parts 11 are respectively located on the two long sides and two short sides of the rectangular plate; two of the six positioning connecting parts 11 are located on the two short sides, and the other four are located on the two long sides. Ideally, the positioning connecting parts 11 should be located in the middle of the short / long sides so that force can be applied evenly to both sides of the short / long sides during connection.

[0045] The positioning connection part 11 and the cover 10 can be integrally formed, or they can be connected by a fixed connection method such as welding. In this embodiment, the positioning connection part 11 is set on the inner wall surface 102 of the cover 10, and the positioning connection part 11 and the cover 10 are integrally formed.

[0046] The positioning connection part 11 can take various forms. For example, it can be a long strip-shaped block, with its upper side integrally formed with the inner wall 102 of the cover 10. The lower side of the long strip-shaped block is a plug-in part, which is inserted into the component that mates with the cover 10 during use to achieve a locking connection. A guide surface 111 is also provided on the lower side of the positioning connection part 11. The guide surface 111 guides the plug-in part during insertion, making the insertion smoother. The guide surface 111 can be an arc surface or a sloped plane, and the inclination direction of the arc surface or sloped plane is related to the mating component.

[0047] Optionally, the inner wall surface 102 of the cover 10 is provided with a first groove 104, and one end of the through hole 101 is located in the first groove 104; and / or, the outer wall surface 103 of the cover 10 is provided with a second groove 105, and the other end of the through hole 101 is located in the second groove 105.

[0048] The aforementioned positioning cover 1 is applied to the filter in the generator controller. The positioning cover 1 is used to position the thermal pad 4 on the copper busbar 3. The following is a detailed explanation using the positioning cover 1 to position the thermal pad 4 as an example.

[0049] refer to Figure 4 and Figure 5This utility model also provides a filter, including a filter housing 2, copper busbars 3, a thermal pad 4, and the aforementioned positioning cover 1. Two copper busbars 3 are provided, both disposed on the filter housing 2, spaced apart to prevent direct electrical conduction and short circuits. The thermal pad 4 is laid on the surface of the copper busbars 3, dissipating heat from the copper busbars 3. The thermal pad 4 needs to possess high temperature resistance and excellent insulation properties; for example, it can be made of epoxy resin or polyurethane. The material of the thermal pad 4 is not limited here.

[0050] Two thermal pads 4 are respectively covered and attached to two copper busbars 3. The cover 10 of the positioning cover 1 presses on the thermal pads 4. The inner wall surface 102 of the cover 10 is in contact with the surface of the thermal pads 4. The positioning connection part 11 of the positioning cover 1 is connected to the filter housing 2. The connection between the positioning connection part 11 and the filter housing 2 will apply a pressing force in the thickness direction to the thermal pads 4, so that the cover 10 presses the thermal pads 4 tightly on the copper busbars 3, preventing the thermal pads 4 from shifting. The thermal pads 4 and the copper busbars 3 are in close contact, so the heat dissipation effect of the copper busbars 3 is guaranteed, and the copper busbars 3 will not be exposed due to the displacement of the thermal pads 4. This helps to reduce the possibility of creepage or leakage, and can improve the safety of the filter during use.

[0051] Since the inner wall surface 102 of the cover 10 is also provided with a first groove 104, the heat-conducting pad 4 can be locked in the first groove 104, further limiting the heat-conducting pad 4 and preventing the heat-conducting pad 4 from shifting. Moreover, one end of the through hole 101 is located in the first groove 104, so the surface of the heat-conducting pad 4 can be exposed to the outer wall surface 103 of the cover 10 through the through hole 101, thereby facilitating heat exchange of the heat-conducting pad 4.

[0052] It should be noted that the size of the thermal pad 4 is larger than the size of the through hole 101 to prevent the thermal pad 4 from falling out of the through hole 101. For example, the through hole 101 is a rectangular hole, and the thermal pad 4 is a rectangular pad. The size of the rectangular pad is adapted to the size of the first groove 104, and the length and width of the rectangular pad are larger than the length and width of the rectangular hole, respectively.

[0053] In this embodiment, the positioning connection part 11 is an elongated plug-in block. The upper half of the plug-in block is fixed to the inner wall surface 102 of the cover 10, and the lower half of the plug-in block is provided with an inclined plane. The inclined plane is located near the middle of the cover 10 and extends from the lower part of the plug-in block to the middle of the cover 10. The plug-in block is also provided with a snap-fit ​​platform located at the end of the inclined plane. The outer wall of the filter housing 2 is provided with a plug-in hole 20. The shape and size of the plug-in hole 20 are adapted to the plug-in block. When the plug-in block is inserted into the plug-in hole 20, the inclined plane can guide along the filter housing 2, and then the snap-fit ​​platform snaps into the plug-in hole 20, thereby connecting the positioning cover 1 to the filter housing 2.

[0054] refer to Figure 6 and Figure 7 The filter also includes a housing 5, on which a heat dissipation part 50 is provided. The heat dissipation part 50 is a protruding bump. The bump is adapted to the second groove 105 on the outer wall surface 103 of the cover 10, so that the bump can be inserted into the second groove 105. The bump is in contact with the thermal pad 4, thereby transferring the heat on the thermal pad 4.

[0055] A water pipe 51 is provided at the lower part of the heat dissipation section 50. By passing a cooling medium through the water pipe 51, the heat on the heat-conducting pad 4 can be carried away, thereby dissipating heat for the copper busbar 3. The water pipe 51 has an inlet and an outlet (not shown in the figure). The water pipe 51 flows through the heat dissipation section 50 and carries away the heat from the heat-conducting pad 4 above, thereby continuously cooling the copper busbar 3.

[0056] Of course, the filter also includes other components, but since the filter used by the generator controller is an existing device, it will not be described in detail.

[0057] An embodiment of this utility model also provides an automobile, including the above-mentioned positioning cover 1 or filter, which has all the functions of the positioning cover 1.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
