[0051] Figures 1 to 8 Shows various aspects of the oil pot assembly 10 of the present application. The oil pot assembly 10 may include: a housing 100, an input component 200, a float 300, etc.
[0052] The housing 100 can enclose an internal cavity and has an outer wall and an inner wall. In one embodiment, the housing 100 can be made of plastic and then assembled to the adapter body. The housing 100 can include: an input portion 110, a through hole 120, a float cavity 130, a liquid suction cavity 140, etc. In one embodiment, the housing 100 can be formed by assembling multiple components. For example, the housing 100 can include an upper half and a lower half, and the upper half and the lower half are assembled together by welding.
[0053] The input portion 110 and the through hole 120 can be located at the vertical top of the float cavity 130. The input portion 110 can be a part of the housing 100, and at least part of its outer surface is configured to have an arc-shaped cross section. In one embodiment, the outer surface of the input portion 110 can be configured in one of the following shapes: a part of a cylinder, a part of a sphere, a part of an ellipsoid, or a combination thereof. The through hole 120 can extend through the housing 100 at the input portion 110 and communicate with the float cavity 130. In one embodiment, the input portion 110 can form at least a part of the perimeter of the float cavity 130.
[0054] The input portion 110 can include a first identifier 111. As Figure 4 shown, the first identifier 111 can be a raised structure and is positioned near the through hole 120.
[0055] In addition, the sizes of the through hole 120 and the float cavity 130 can be set to be large enough. For example, the through hole 120 allows at least the rod 230 to be inserted therein, and at the same time allows the end of the input tube 220 to communicate with the float cavity 130. The float cavity 130 allows at least the float 300 to move freely therein, and the float 300 is separated from the inner wall of the float cavity 130.
[0056] The float cavity 130 and the liquid suction cavity 140 can be different parts of the internal cavity of the housing 100 and are arranged adjacent to each other. In one embodiment, the float cavity 130 and the liquid suction cavity 140 are communicated through one or more grooves or holes. A liquid suction port 141 can be provided at the vertical bottom of the liquid suction cavity 140.
[0057] The input component 200 can cooperate with the float 300 and be adapted to the housing 100. Figures 5 to 6 One embodiment of the input component 200 and the float 300 is shown, and Figures 7 to 8 another embodiment of the input component 200 and the float 300 is shown. For different floats 300, the input component 200 can have different structures.
[0058] As shown in the figure, the input component 200 may include: a mating portion 210, an input pipe 220, a rod 230, a sensor 240, an interface portion 250, etc. The input component 200 may be integrally formed. The input component 200 may be made of the same material as the housing 100 and connected to the housing 100 by welding.
[0059] The inner surface of the mating portion 210 may at least partially match the outer surface of the input portion 110. In one embodiment, the inner surface of the mating portion 210 may be configured in one of the following shapes: a part of a cylinder, a part of a sphere, a part of an ellipsoid, or a combination thereof. The mating portion 210 may be adapted to the input portion 110 and attached to the input portion 110 at least within a certain angular range.
[0060] The side surface of the mating portion 210 may include a plurality of second identifiers 211. The second identifiers 211 may be patterns, indentations, or protrusions. As Figure 2 、 5 and shown in FIG. 7, the plurality of second identifiers 211 may be arranged along the circular arc cross-sectional contour of the mating portion 210 and positioned adjacent to the first marker 111 of the input portion 110.
[0061] The input pipe 220 may pass through the mating portion 210, and when the mating portion 210 is adapted to the input portion 110, the input pipe 220 is also connected to the through hole 120 on the input portion 110. When installed in place, the input pipe 220 may form a certain angle with the vertical direction or the direction of gravity.
[0062] One end of the rod 230 extends from the mating portion 210, and the other end extends into the housing 100. More specifically, the other end of the rod 230 may extend into the float chamber 130. At least a part of the rod 230 needs to be oriented in the vertical direction. For different assembly requirements, the orientation of the rod 230 may be changed by changing the matching angle between the mating portion 210 and the input portion 110. In the illustrated embodiment, at least a part of the rod 230 extends along a straight line and is oriented in the vertical direction. One end of the rod 230 may be integrally formed with the mating portion 210, and thus, the rod 230 has a fixed orientation relative to the mating portion 210.
[0063] The sensor 240 and the interface portion 250 may be provided within the input component 200 and form part of the sensing circuit. In the illustrated embodiment, the sensor 240 may be a Hall sensor or a reed switch sensor. Figure 7 A Hall sensor arranged along the rod 230 is shown, and the cross-section of the rod 230 is generally circular. Figure 5The input component 200 using a reed type sensor 240 is shown, and a plurality of guiding ribs 233 are arranged on the outer surface of the rod 230. Although not shown, it is easily understood that the reed sensor can be disposed inside the rod 230, as Figure 12 schematically shown therein. The sensor 240 can be electrically connected to the interface portion 250, and the interface portion 250 can connect electrical terminals so as to electrically connect the sensor 240 to the controller 30. The interface portion 250 can extend from the side surface of the mating portion 210.
[0064] The float 300 can be disposed within the float chamber 130 and movably sleeved on the rod 230. In one embodiment, the float 300 includes an inner wall and an outer wall, wherein the inner wall is the side of the float 300 facing the rod 230, and the outer wall is the side of the float 300 facing away from the rod 230. The float 300 can be separated from the inner wall of the float chamber 130. The float 300 can be made of foamed plastic, and its density is less than the density of the brake fluid, so that the whole float can float up and down with the change of the liquid level height of the brake fluid. The bottom of the float 300 can include one or more protrusions 301 to prevent the float 300 from adhering to the inner wall of the housing 100.
[0065] Figure 6 An embodiment of the float 300 is shown, which can be used in cooperation with the reed type sensor 240. In this embodiment, the inner wall of the float 300 is configured to be adapted to Figure 5 the rod 230 and the guiding ribs 233 therein, and includes a plurality of guiding grooves 303. The first magnet 331 is mounted at the outer wall of the float 300, and as Figure 12 shown, the first magnet 331 is spaced apart from the rod 230, and a part of the float 300 is disposed between the first magnet 331 and the rod 230. The cooperation of the guiding grooves 303 and the guiding ribs 233 positions the first magnet 331 at a specific position relative to the rod 230. In addition, the guiding grooves 303 and the guiding ribs 233 can be arranged to provide an anti-misinsertion structure. That is, the float 300 can only be inserted into the rod 230 in a specific orientation, which enables the first magnet 331 to be accurately positioned at a position where it can be sensed by the reed type sensor 240.
[0066] In Figure 6 the shown embodiment, recesses are arranged around the first magnet 331 for the needs of manufacturing and facilitating the installation of the magnet. Separate grooves are also included on the outer wall of the float 300, which are generated during the molding process and are not necessary.
[0067] Figure 8Shows another embodiment of the float 300, which can be used in conjunction with a sensor 240 of the Hall sensor type. A series of sensors 240 can be arranged along the length of the rod 230. The outer wall of the rod 230 can be configured to be generally cylindrical, and the inner wall of the float 300 can be configured to be cylindrical to match the outer wall of the rod 230. The second magnet 332 can be positioned at the inner wall of the float 300, and as Figures 9 to 11 shown, the second magnet 332 is positioned to directly face the rod 230.
[0068] In Figure 8 the embodiment shown, the outer wall of the float 300 is configured to be cylindrical, such that the entire float 300 presents an annular shape. As Figures 9 to 11 shown, the bottom of the float 300 is provided with a protrusion 301 to prevent the float 300 from adhering to the inner wall of the housing 100. The outer wall of the float 300 also includes grooves, which are also for the needs during the manufacturing process and are not necessary.
[0069] Figures 9 to 12 Shows a cross-section of the oil can assembly of the present application at different installation angles. Figures 9 to 11 The embodiment shown is the one using the Hall sensor and the second magnet 332, that is Figure 7 and Figure 8 the solutions shown. Figure 12 The embodiment shown is the one using the reed switch sensor and the first magnet 331, that is Figure 5 and Figure 6 the solutions shown. In Figures 9 to 11 , the mating part 210 and the input part 110 are attached at different angles. For example, Figure 9 in the case of Figure 10 the angle can be considered as 0 degrees, Figure 11 in the case of
[0070] Figure 13 the angle can be considered as 10 degrees, and Figure 11 in the case of
[0070] Figure 13 the angle can be considered as 20 degrees. In any case, by adjusting the relative angle between the mating part 210 and the input part 110, it can be ensured that the rod 230 is oriented in the vertical direction or the direction of gravity, such that the float 300 can reflect the level height of the brake fluid under the buoyancy of the brake fluid. Therefore, the input component 200 can function as a liquid level indicator.
[0070] Figure 13 Shows an embodiment of the adapter of the present application. The adapter can include: the oil can assembly 10, the adapter body 20, the controller 30, etc. The oil can assembly 10 can be arranged at the top of the adapter body 20 and supply brake fluid to the adapter body 20. By adopting the oil can assembly 10 of the present application, the adapter body 20 can be installed at different angles, and the oil can assembly 10 can still ensure the orientation of the rod 230 and the liquid level indicating function of the float 300.
[0071] The controller 30 can be electrically connected to the sensors of the oil pot assembly 10, for example, by inserting an electrical plug into the interface portion 250. The controller 30 can also be electrically connected to the adapter body 20.
[0072] In one embodiment, the controller 30 can be configured to ignore the sensing signal from the sensor 240 within a predetermined time when performing a liquid suction operation on the working fluid or brake fluid in the oil pot assembly 10. This is because the liquid suction operation is carried out through the liquid suction port 141. After the start of the liquid suction operation, the brake fluid in the liquid suction chamber 140 and the float chamber 130 in fluid communication therewith will be sucked away in a short time, resulting in a rapid drop in the liquid level of the brake fluid. The float 300 and the sensor 240 will sense such changes and issue a signal of the liquid level drop. At this time, the oil pot assembly will replenish the brake fluid through the input pipe 220, but it takes a certain amount of time for the brake fluid to flow into place. Therefore, within the predetermined time for replenishing the brake fluid, the controller 30 can ignore the liquid level drop signal from the sensor 240, thereby avoiding issuing unnecessary alarms to the vehicle driver. The predetermined time can be between 200 milliseconds and 500 milliseconds. In one embodiment, the predetermined time can be about 300 milliseconds.
[0073] The oil pot assembly and the adapter of the present application have the advantages of being simple, reliable, easy to implement, and convenient to use, and can provide improved installation flexibility. By adopting the oil pot assembly and the adapter of the present application, products with different installation angles can be assembled with the same set of components, thereby reducing the production, design, and installation costs and bringing significant economic benefits.
