Description

Technical Field

[0001] This application relates to the field of brake fluid filling, and more particularly to an ABS pump clamping filling device and filling method. Background Technology

[0002] In the automotive manufacturing and repair industry, the performance of the braking system is crucial to vehicle safety. As a core component of the ABS (Anti-lock Braking System), the filling of brake fluid into the ABS pump is a critical step in ensuring the system's proper functioning. With the continuous development of the automotive industry, the requirements for the reliability and stability of braking systems are increasing, prompting companies to constantly seek more efficient and precise ABS pump filling technologies. High-quality brake fluid filling not only ensures the ABS pump performs at its best but also effectively extends the lifespan of the braking system and reduces safety hazards caused by brake failure.

[0003] ABS pumps have wheel cylinder connection holes and master cylinder connection holes that communicate with the brake fluid reservoir. These two connection holes are typically located on different end faces of the ABS pump. Brake fluid is added through the wheel cylinder connection hole, and the master cylinder connection hole needs to be sealed during the filling process to prevent leakage. Currently, the industry commonly uses a handheld filling gun for manual filling. However, manual filling has limitations: the sealing is unstable during filling, especially when the master cylinder connection hole also needs to be sealed, making the operation even more inconvenient. Furthermore, to ensure the brake fluid fully fills the reservoir, it is usually filled from below, with the wheel cylinder connection hole opening facing downwards, and the brake fluid gradually fills the reservoir from bottom to top. However, filling from below is inconvenient to operate and makes it difficult for personnel to observe the sealing. Any shaking can cause brake fluid to leak due to gravity, and may even contaminate the filling gun. Summary of the Invention

[0004] To address the problems of inconvenient operation and easy leakage when adding from below, this application provides an ABS pump clamping and adding device and a adding method.

[0005] In a first aspect, this application provides an ABS pump clamping and filling device, including: a placement seat, a clamping assembly, a sealing assembly, a wiring connection assembly, and a filling assembly;

[0006] The placement seat is used to support the ABS pump, and the opening of the wheel cylinder connection hole of the ABS pump faces the placement seat;

[0007] The clamping assembly is used to clamp and fix the ABS pump;

[0008] The sealing assembly is used to at least partially penetrate into the main cylinder connection hole of the ABS pump and seal the main cylinder connection hole;

[0009] The ABS pump has a wiring connector; the wiring connector assembly is used to connect to the wiring connector.

[0010] The filling component is connected to the wheel cylinder connection hole and is used to fill the ABS pump with brake fluid.

[0011] By adopting the above technical solutions, the mounting base can support the ABS pump; the clamping assembly can prevent the ABS pump from shifting or shaking; the sealing assembly can seal the master cylinder connection hole to prevent leakage during filling; the wiring plug assembly can connect the wiring by plugging it into the wiring socket; and the filling assembly can connect to the wheel cylinder connection hole with the opening facing downward to realize the filling of brake fluid.

[0012] Optionally, a positioning post is vertically provided at the top of the placement seat. When the ABS pump is placed on the placement seat, the positioning post at least partially penetrates into the wheel cylinder connection hole and engages with the wheel cylinder connection hole for limiting. A first filling channel is provided inside the positioning post along its own axis, and a second filling channel is provided inside the placement seat. The opposite ends of the first filling channel are respectively connected to the wheel cylinder connection hole and the second filling channel. A first step is provided inside the wheel cylinder connection hole, and a flexible sealing part is provided at the end of the positioning post away from the placement seat. The flexible sealing part is used to abut against the first step.

[0013] The filling component is connected to the second filling channel.

[0014] By adopting the above technical solution, the positioning column and the wheel cylinder connection hole limit cooperation can ensure the accurate placement of the ABS pump. The first filling flow channel and the second filling flow channel are connected to facilitate the filling of brake fluid into the wheel cylinder connection hole. The flexible sealing part abuts against the first step to prevent brake fluid leakage. The clamping component can fix the ABS pump. The sealing component can block the master cylinder connection hole. The filling component can realize the filling of brake fluid.

[0015] Optionally, the clamping assembly includes a first drive unit and a pressure plate;

[0016] When the ABS pump is placed on the mounting base, the pressure plate is located on the side of the ABS pump away from the mounting base; the first drive unit is connected to the pressure plate and is used to drive the pressure plate closer to the ABS pump, thereby clamping the ABS pump and causing the flexible sealing part to abut against the first step.

[0017] By adopting the above technical solution, the pressure plate driven by the first drive unit is brought close to the ABS pump, which can clamp the ABS pump. At the same time, by pressing down on the ABS pump, the flexible sealing part of the positioning column can be pressed against the first step in the wheel cylinder connection hole, ensuring the sealing of the wheel cylinder connection hole, which is conducive to the smooth operation of subsequent brake fluid filling.

[0018] Optionally, the first step is frustoconical in shape. When the ABS pump is placed on the mounting base, the smaller end of the first step faces downward, and the first step at least partially penetrates into the flexible sealing part and abuts against the inner wall of the flexible sealing part.

[0019] By adopting the above technical solution, the smaller, downward-facing, and at least partially inserted first step of the frustum-shaped section abuts against the inner wall of the flexible seal, further enhancing the connection stability and sealing between the wheel cylinder connection hole and the positioning post. Specifically, the clamping assembly presses down on the ABS pump, thereby fixing the ABS pump while simultaneously ensuring that the first step at least partially penetrates the flexible seal and abuts against its inner wall. This helps reduce brake fluid leakage and better achieves the limiting fit between the positioning post and the wheel cylinder connection hole, ensuring a smooth filling process.

[0020] Optionally, the ABS pump clamping and filling device further includes a limiting component, which includes multiple limiting members; when the ABS pump is placed on the placement seat, the multiple limiting members surround the side of the ABS pump; the height of the limiting members is higher than the height of the positioning post, and the multiple limiting members are used together to limit the ABS pump so that the positioning post is aligned with the wheel cylinder connection hole.

[0021] By adopting the above technical solution and setting a limiting component, multiple limiting parts can limit the ABS pump by surrounding the side of the ABS pump. The height of the limiting parts is higher than the height of the positioning post, so that the ABS pump is already in a limited state by the limiting parts before the positioning post is inserted into the wheel cylinder connection hole, which makes it easier for the positioning post to be aligned with the wheel cylinder connection hole and improves the accuracy of the ABS pump placement and positioning.

[0022] Optionally, a second step is provided on the bottom of the inner wall of the flexible sealing part, and the second step is used to abut against the bottom of the first step.

[0023] By adopting the above technical solution, the bottom of the second step abuts against the bottom of the first step, which can limit the first step and prevent it from being inserted too much; and the bottom of the second step abuts against the bottom of the first step, which can effectively prevent brake fluid from entering between the outer wall of the first step and the inner wall of the flexible sealing part, further enhancing the sealing between the wheel cylinder connection hole and the positioning pin and reducing brake fluid leakage.

[0024] Optionally, the positioning post includes a flexible sealing part, a positioning part, and an annular support part;

[0025] The flexible sealing part is located on the top of the positioning part; the annular support part is sleeved on the positioning part, and the outer diameter of the annular support part is larger than the orifice diameter of the wheel cylinder connection hole. The annular support part is used to support the ABS pump and seal the wheel cylinder connection hole.

[0026] By adopting the above technical solution, the positioning column is equipped with a flexible sealing part, a positioning part and an annular support part, which can better achieve the positioning and sealing of the ABS pump. The outer diameter of the annular support part is larger than the diameter of the wheel cylinder connection hole, so that the annular support part can support the ABS pump and seal the wheel cylinder connection hole.

[0027] Optionally, the flexible sealing part, the positioning part, and the annular support part are integrally formed; or,

[0028] The flexible sealing part is located on the top of the positioning part; the positioning part is a rigid component, and the positioning part has a truncated cone portion that is narrower at the top and wider at the bottom. The truncated cone portion is matched with the wheel cylinder connection hole for limiting fit; the bottom diameter of the truncated cone portion is larger than the opening diameter of the wheel cylinder connection hole, and the annular support part is sleeved on the truncated cone portion. The inner wall of the annular support part is pressed against the truncated cone portion by the extrusion of the ABS pump.

[0029] By adopting the above technical solution, if the flexible sealing part, positioning part, and annular support part are integrally formed, their preparation is relatively convenient; if the positioning part is a rigid component, the conical part and the wheel cylinder connection hole are matched in a limiting manner, which facilitates precise positioning and can better realize the matching between the positioning post and the wheel cylinder connection hole, improving assembly accuracy and stability; the bottom diameter of the conical part is larger than the orifice diameter of the wheel cylinder connection hole, which allows the ABS pump to squeeze the conical part downwards, and the annular support part is sleeved on the conical part. The inner wall of the annular support part is pressed against the conical part by the squeezing of the ABS pump, which can enhance the sealing effect on the wheel cylinder connection hole and ensure that there is no leakage during the brake fluid filling process.

[0030] Optionally, the line connection assembly includes a second drive unit, a mounting bracket, a guide rail, a plug, a buffer, and a pressure sensor;

[0031] The plug is mounted on the mounting bracket; the mounting bracket is slidably mounted on the guide rail;

[0032] The second drive unit is connected to the mounting bracket and is used to drive the mounting bracket to slide along the guide rail so that the plug is inserted into the line socket;

[0033] The pressure sensor is mounted on the mounting bracket;

[0034] The buffer includes a sleeve, a piston, and an elastic element; one end of the piston is inserted into the sleeve and slidably connected to the sleeve; the elastic element is disposed inside the sleeve, and its opposite ends are respectively connected to the sleeve and the piston; when the plug contacts the line socket and is gradually inserted, the piston abuts against the pressure sensor and slows down the movement speed of the plug.

[0035] By adopting the above technical solution, in the line plug assembly, the second drive unit drives the mounting bracket to slide along the guide rail to plug the plug into the line socket. The piston of the buffer abuts against the pressure sensor to slow down the movement speed of the plug, avoid damage to the components during the plugging process, and ensure that the plug and line socket are plugged in stably and safely. The plugging status of the plug and line socket can be determined according to the pressure reading of the pressure sensor.

[0036] On the other hand, this application also provides a filling method based on the ABS pump clamping filling device described in any of the above claims, comprising the following steps:

[0037] With the wheel cylinder connection hole of the ABS pump facing downwards, the ABS pump is placed between multiple limiting parts, so that the positioning pin passes into the wheel cylinder connection hole and is limited and engaged with the wheel cylinder connection hole. Under the gravity of the ABS pump, the first step aligns with and abuts against the end of the flexible sealing part.

[0038] The ABS pump is pressed down by the clamping assembly, so that the first step penetrates into the flexible sealing part until it abuts against the second step.

[0039] The master cylinder connection hole is sealed using a sealing assembly;

[0040] The plug is inserted into the line socket using the line connection assembly;

[0041] Brake fluid is added to the wheel cylinder connection hole using the filling assembly.

[0042] By adopting the above technical solution, the ABS pump wheel cylinder connection hole is placed downwards between the limiting components, allowing the positioning pin to penetrate the wheel cylinder connection hole for limiting and engagement. Gravity is used to align and abut the end of the flexible sealing part, achieving initial positioning and sealing. The clamping assembly is used to press down, causing the first step to penetrate the flexible sealing part until it abuts against the second step, which strengthens the seal. The sealing assembly is used to seal the master cylinder connection hole to prevent brake fluid leakage. The wiring connector assembly is used to connect the plug to the wiring socket for easy subsequent operation and control. Brake fluid is added to the wheel cylinder connection hole through the filling assembly, thus realizing the filling of brake fluid into the ABS pump.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By using the positioning pin and the wheel cylinder connection hole for limiting fit and the flexible sealing part to abut against the first step, precise positioning and good sealing can be achieved to avoid brake fluid leakage; the filling component fills brake fluid into the wheel cylinder connection hole from bottom to top through the first filling channel and the second filling channel, which can make the brake fluid fill evenly and the sealing performance is good during the filling process;

[0045] 2. The clamping assembly can drive the pressure plate close to the ABS pump, thereby stably clamping the ABS pump and causing the first step to penetrate at least partially into the flexible seal and abut against the inner wall of the flexible seal. This not only enhances the connection stability between the wheel cylinder connection hole and the positioning post, but also prevents brake fluid from getting on the outer wall of the first step, thus avoiding contamination of the first step and the subsequent brake fluid dripping from the first step.

[0046] 3. The bottom of the second step abuts against the first step, which can limit the insertion of the first step and prevent it from being inserted too far. Furthermore, the bottom of the second step abuts against the first step, which can prevent brake fluid from entering between the outer wall of the first step and the inner wall of the flexible seal when the injection pressure is too high, thus reducing the probability of contamination of the outer wall of the first step and brake fluid leakage.

[0063] The following is in conjunction with the appendix Figures 1 to 7 This application will be described in further detail.

[0064] like Figures 1 to 3 As shown in the figure, this application discloses an ABS pump clamping and filling device, including a placement seat 1, a limiting component 2, a clamping component 3, a sealing component 4, a wiring plug-in component 5, and a filling component 6.

[0065] Specifically, the top of the placement seat 1 is horizontal, and the placement seat 1 is used to support the ABS pump 200.

[0066] like Figures 2 to 3 As shown, the limiting assembly 2 includes multiple limiting members, all of which are connected to the placement base 1. The structures of these limiting members may be identical or not entirely the same. For example, the multiple limiting members include a first limiting member 21, a second limiting member 22, and two sets of third limiting members 23. The first limiting member 21 and the second limiting member 22 are located on opposite sides of the placement base 1 along a first direction; the two sets of third limiting members 23 are located on opposite sides of the placement base 1 along a second direction. Both the first and second directions are horizontal and perpendicular to each other.

[0067] like Figures 2 to 3As shown, a positioning post 7 is vertically provided on the top of the placement base 1, and the height of the limiting member is higher than the height of the positioning post 7. When placing the ABS pump 200, the ABS pump 200 is placed between multiple limiting members with the opening of the wheel cylinder connection hole 201 facing the placement base 1 (downward). The multiple limiting members simultaneously limit the ABS pump 200, so that the wheel cylinder connection hole 201 can be aligned with the positioning post 7, and the positioning post 7 can at least partially penetrate into the wheel cylinder connection hole 201 and engage with the wheel cylinder connection hole 201 for limiting.

[0068] The positioning post 7 has a first filling channel along its own axis, and the placement seat 1 has a second filling channel. The two ends of the first filling channel are respectively connected to the wheel cylinder connection hole 201 and the second filling channel. The filling assembly 6 is connected to the second filling channel and is used to fill the second filling channel with brake fluid, so that the brake fluid enters the ABS pump 200 from the wheel cylinder connection hole 201.

[0069] like Figure 2 As shown, the filling assembly 6 includes a filling connector that communicates with the second filling channel. When brake fluid needs to be added, the brake fluid delivery pipe can be connected to the filling connector via a (quick-connect) connector or a connecting flange.

[0070] like Figures 2 to 6 As shown, the wheel cylinder connection hole 201 is provided with a first step 2011, and the end of the positioning post 7 away from the placement seat 1 is provided with a flexible sealing part 71. The flexible sealing part 71 is used to abut against the first step 2011 to achieve a seal and prevent leakage during filling.

[0071] like Figures 1 to 3 As shown, the clamping assembly 3 is used to clamp the ABS pump 200. In this embodiment, the clamping assembly 3 includes a first drive unit 31 and a pressure plate. When the ABS pump 200 is placed on the placement seat 1, the pressure plate is located on the side of the ABS pump 200 away from the placement seat 1. The first drive unit 31 is connected to the pressure plate and is used to drive the pressure plate closer to the ABS pump 200, thereby pressing the ABS pump 200 tightly. The downward pressure can also cause the flexible sealing part 71 to abut against the first step 2011, improving the sealing effect.

[0072] Since the conventional ABS pump 200 contains components such as sensors and valves, these components need to be powered or transmit signals (for example, when the valves that control the opening and closing of the control wheel cylinder connection hole 201 and the master cylinder connection hole 202 are solenoid valves, an external line is required to control them), the ABS pump 200 has a line socket 203.

[0073] like Figures 2 to 4 As shown, the line plug assembly 5 includes a second drive unit 51, a mounting bracket 52, a guide rail 53, a plug 54, a buffer 55, and a pressure sensor.

[0074] The plug 54 is mounted on the mounting bracket 52, which is slidably mounted on the guide rail 53. The second drive unit 51 is connected to the mounting bracket 52 and is used to drive the mounting bracket 52 to slide along the guide rail 53 so that the plug 54 is inserted into the line socket 203.

[0075] The pressure sensor is mounted on the mounting bracket 52. The buffer 55 includes a sleeve 551, a piston 552, and an elastic element. The elastic element can be a spring. One end of the piston 552 passes into the sleeve 551 and is slidably connected to the sleeve 551. The elastic element is located inside the sleeve 551, and its opposite ends are connected to the sleeve 551 and the piston 552, respectively. When the plug 54 contacts the wiring socket 203 and is gradually inserted, the piston 552 abuts against the pressure sensor, applying resistance to the mounting bracket 52 through the piston 552, thereby slowing down the movement speed of the plug 54 and preventing damage caused by excessive insertion speed.

[0076] Specifically, when the pressure sensor just contacts the piston 552, one of the plug 54 and the wiring socket 203 is also just beginning to insert into the other. The connection status of the plug 54 and the wiring socket 203 can be determined from the pressure reading of the pressure sensor. For example, if the pressure value remains low for a period of time after the pressure sensor starts displaying a reading, it may be because the plug 54 has not yet been inserted into the wiring socket 203, and the wiring socket 203 is not applying force to the plug 54. This situation may be due to a positioning problem of the ABS pump 200 and should be checked promptly.

[0077] For example, if the pressure sensor registers a high pressure reading, it may be due to misalignment between the plug 54 and the wiring socket 203, causing them to abut each other. In this case, the machine should be stopped immediately for inspection. Inspection can be performed manually or using a visual inspection device (e.g., taking photos with an industrial camera and then analyzing the results with the controller). Furthermore, since both the plug 54 and the wiring socket 203 have outer covers 2031 to protect their internal structures (pins or insertion holes), the phrase "one of the plug 54 and the wiring socket 203 is just beginning to be inserted into the other" refers to the outer covers 2031 just beginning to engage. It can be configured so that when the outer covers 2031 begin to engage, the internal structures are not yet in contact, ensuring that even if they are misaligned, only the outer covers 2031 abut against each other without damaging the internal structures. Further, rubber pads can be placed at the ends of the outer covers 2031 to provide cushioning and protection, preventing damage to the outer covers 2031.

[0078] like Figures 2 to 3As shown, the sealing assembly 4 is used to seal the master cylinder connection hole 202 of the ABS pump 200. In this embodiment, the sealing assembly 4 includes a third drive unit 41, a push plate 42, a push rod 43, a sealing head 44, and a return spring 45. The push rod 43 is slidably connected to the placement seat 1, one end of the push rod 43 is connected to the sealing head 44, and the other end has a limiting protrusion. The return spring 45 is sleeved on the push rod 43, one end of the return spring 45 abuts against the placement seat 1, and the other end abuts against the limiting protrusion. The third drive unit 41 is connected to the push plate 42. When the third drive unit 41 drives the push plate 42 to move, the push plate 42 can push the push rod 43 to move, thereby blocking the master cylinder connection hole 202 with the sealing head 44 to prevent brake fluid leakage. In this embodiment, the sealing head 44 is a rubber head. The first drive unit 31, the second drive unit 51, and the third drive unit 41 are all cylinders.

[0079] like Figure 2 and Figure 7 As shown, in some embodiments, the first step 2011 is frustoconical. When the ABS pump 200 is placed on the mounting base 1, the smaller end of the first step 2011 faces downwards, and the first step 2011 at least partially penetrates into the flexible sealing part 71 and abuts against the inner wall of the flexible sealing part 71. By allowing the first step 2011 to penetrate into the flexible sealing part 71, the first step 2011 and the flexible sealing part 71 can be stably connected, avoiding the impact on sealing performance due to vibration or other reasons. In addition, the conical outer wall of the first step 2011 abuts against the inner wall of the flexible sealing part 71. During filling, brake fluid will not adhere to the conical outer wall of the first step 2011, thus avoiding contamination and preventing brake fluid dripping from the conical outer wall of the first step 2011 laterally. Similarly, the top and inner side of the flexible seal 71 will not be contaminated with brake fluid, which prevents brake fluid from sliding down the outer wall of the flexible seal 71 and causing contamination, and also prevents the flexible seal 71 from contaminating the first step 2011 when it is connected to the first step 2011 of other ABS pumps 200 again.

[0080] Furthermore, a second step 711 is provided on the bottom of the inner wall of the flexible sealing part 71. After the ABS pump 200 is positioned, the bottom of the first step 2011 can abut against the second step 711. Under the downward pressure of the pressure plate, the first step 2011 and the second step 711 are pressed together, which helps to further improve the sealing performance and also prevents brake fluid from flowing between the conical outer wall of the first step 2011 and the inner wall of the flexible sealing part 71 when the injection pressure is too high.

[0081] Specifically, the inner diameter of the flexible sealing part 71 at the top of the second step 711 is equal to the inner diameter of the first step 2011 at the bottom, so that the bottom of the first step 2011 will not get brake fluid during filling, reducing the probability of dripping at the bottom of the first step 2011 after filling.

[0082] In some embodiments, the positioning post 7 includes a flexible sealing portion 71, a positioning portion 72, and an annular support portion 73. The flexible sealing portion 71 is disposed on the top of the positioning portion 72. The annular support portion 73 is sleeved on the positioning portion 72, and the bottom of the annular support portion 73 abuts against the placement seat 1. The outer diameter of the annular support portion 73 is larger than the orifice diameter of the wheel cylinder connection hole 201. The annular support portion 73 is used to support the ABS pump 200. When the ABS pump 200 presses on the annular support portion 73, the annular support portion 73 can seal the orifice of the wheel cylinder connection hole 201, further preventing brake fluid leakage.

[0083] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the flexible sealing part 71, the positioning part 72 and the annular support part 73 are integrally formed, which makes the preparation more convenient, and all of them can be made of rubber.

[0084] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments, the flexible sealing part 71 is disposed on the top of the positioning part 72. The positioning part 72 is a rigid component, and the material may be stainless steel. The positioning part 72 has a truncated cone part 721 that is narrower at the top and wider at the bottom. The truncated cone part 721 is matched with the wheel cylinder connection hole 201 to further improve the positioning accuracy of the ABS pump 200. The bottom diameter of the truncated cone part 721 is larger than the opening diameter of the wheel cylinder connection hole 201. The flexible sealing part 71 and the annular support part 73 are made of rubber. The annular support part 73 is sleeved on the truncated cone part 721, and the bottom of the annular support part 73 can abut against the placement seat 1. When the ABS pump 200 is positioned, the ABS pump 200 can press down on the annular support part 73 to flatten the annular support part 73. The annular support part 73 is squeezed by the ABS pump 200 so that its inner hole wall abuts against the truncated cone part 721, thereby improving the sealing performance. By achieving a seal under the pressure of the ABS pump 200, the annular support 73 does not need to be fixedly connected to the frustum 721, making it easy to replace the annular support 73.

[0085] This application also provides a filling method for the ABS pump clamping filling device based on any of the above embodiments, which includes the following steps:

[0086] S100: With the wheel cylinder connection hole 201 of the ABS pump 200 facing downwards, place the ABS pump 200 between multiple limiting members, so that the positioning pin 7 passes into the wheel cylinder connection hole 201 and engages with the wheel cylinder connection hole 201 for limiting. Under the gravity of the ABS pump 200, the first step 2011 aligns with and abuts against the end of the flexible sealing part 71, and the first step 2011 can initially penetrate into the flexible sealing part 71. The placement of the ABS pump 200 can be done manually or by a robot.

[0087] S200: The ABS pump 200 is pressed down by the clamping assembly 3, so that the first step 2011 penetrates into the flexible sealing part 71 until it abuts against the second step 711.

[0088] Specifically, the first drive unit 31 drives the pressure plate to move downward and press down the ABS pump 200, so that the first step 2011 further penetrates into the flexible sealing part 71 until it abuts against the second step 711. At this time, the conical outer wall of the first step 2011 abuts against the inner wall of the flexible sealing part 71.

[0089] S300: The main cylinder connection hole 202 is sealed by the sealing assembly 4. Specifically, the push plate 42 is moved by the third drive unit 41, thereby causing the sealing head 44 to seal the main cylinder connection hole 202.

[0090] S400: The plug 54 is connected to the wiring socket 203 via the wiring connector assembly 5.
