Description

EPBi (the Integrated Electronic Parking Brake System) actuators have been widely used in the development of modern automobiles. In the traditional assembly method, EPBi and brake pipes are assembled separately on the assembly line by multiple workers and workstations, which takes a long time and has poor assembly quality and consistency.

[0003] Therefore, the EPBi subassembly tooling has been introduced in the relevant technology. However, on the one hand, it places great demands on the proficiency and operation of the assembly workers, resulting in a long period of familiarization training for workers and insufficient assembly efficiency for new workers. At the same time, because there are 6 brake pipe interfaces at the EPBi end, facing two directions, workers interfere with each other during assembly and torque application, which is not conducive to operation.

[0049] With the development of automobile intelligence, integrated applications are increasing. EPBi (the Integrated Electronic Parking Brake System) actuators have been widely used in the development of modern automobiles. In the traditional assembly method, EPBi and brake pipes are assembled by multiple workers and workstations on the assembly line respectively, which takes a long time to assemble, and the assembly quality and consistency are poor. Therefore, electronic brake system subassembly tooling has been introduced in the relevant technology, but on the one hand, there are great requirements for the proficiency and operation of the assembly workers, resulting in a long training and familiarization cycle for workers and insufficient assembly efficiency for new workers. At the same time, because EPBi generally has 6 brake pipe interfaces, facing two directions, workers interfere with each other when assembling and torsion, which is not conducive to operation. On the other hand, in the relevant technology, in order to ensure the assembly accuracy, the brake pipe is selected as the positioning reference when designing the operating table of the subassembly device, and the cabin space of different models is different, so each model needs to redesign the pipe clamp and brake pipe separately, which leads to the need for the subassembly device to be redeveloped accordingly. After the development of multiple models, the subassembly device occupies a large space and has a low utilization rate.

[0050] To solve the above problems, an embodiment of the present application provides a subassembly device for an automotive electronic brake system. The present application is further described below in conjunction with the subassembly device shown in the accompanying drawings, its component structure schematic diagram and related embodiments.

[0051] See also Figure 1 , Figure 1 It is a schematic diagram of the EPBi81 structure currently used in large quantities by various automobile OEMs. Although the appearance dimensions of various EPBi81 actuators are different, their structures are basically the same, mainly divided into a motor assembly 811, an HCU (Hydraulic Control Unit) assembly 812 and an ECU (Electronic Control Unit) assembly 813.

[0052] The subassembly device of the automotive electronic brake system provided in the embodiment of the present application refers to Figure 2 The packaging device includes an operating table 1, a first fixed tool 2, at least one second fixed tool 3 and a third fixed tool 4.

[0053] The operating table 1 is provided with a plurality of mounting holes (not shown in the figure), and the plurality of mounting holes can be opened corresponding to the positions of the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4 according to the positional relationship of the pipe clamps 83 of the electronic brake system required by different vehicle models, so as to form different groups of mounting holes for the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4 to select different installation positions; the number of mounting holes in each group corresponds to the required setting for installing the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4.

[0054] The first fixing fixture 2 is arranged on the operating table 1 and is used to fix the EPBi81. For example, the first fixing fixture 2 can be welded or bolted to the operating table 1. When the first fixing fixture 2 can be welded to the operating table 1, the first fixing fixture 2 can be used as a positioning reference to select the installation positions of the second fixing fixture 3 and the third fixing fixture 4 according to the requirements of the electronic brake system required by different vehicle models.

[0055] Reference Figure 5 , Figure 8 and Fig. 9 The second fixing tool 3 includes a first base 31 and a pipe clamp seat 32. The pipe clamp seat 32 is detachably arranged on the first base 31. The first base 31 can be selectively connected to one of the multiple mounting holes on the operating table 1. The pipe clamp seat 32 has a first limiting groove 321. The pipe clamp 83 is arranged on the first limiting groove 321, which is used to position the brake hard pipe 82 so that the pipe clamp 83 is consistent with the fixed position when the pipe clamp 83 is assembled on the car. Among them, the pipe clamp 83 is arranged on the first limiting groove 321, which means that the pipe clamp 83 and the first limiting groove 321 cooperate to limit the brake hard pipe 82. For example, when the opening direction of the clamping groove on the pipe clamp 82 is consistent, the brake hard pipe 82 is first inserted into the first limiting groove 321, and then the pipe clamp 83 is buckled on the brake hard pipe 82, and the pipe clamp 83 is positioned by the wall of the first limiting groove 321. When the opening directions of the positioning grooves on the pipe clamp 83 are inconsistent, first install a part of the brake hard tube 82, then buckle the positioning groove of the pipe clamp 83 with the opening direction facing downward on the corresponding brake hard tube 82 that has been installed, and then install the other part of the brake hard tube 82 on the positioning groove with the opening direction facing upward. The positioning groove of the pipe clamp 83 can be interference fit with the brake hard tube 82, and the brake hard tube 82 can be transition fit or clearance fit with the first limiting groove 321. After the electronic brake system is assembled, the brake hard tube 82 can be disengaged by gently tapping upwards when disassembling, so that it can be separated from the first limiting groove 321, and the pipe clamp 83 is clamped on the brake hard tube 82.

[0056] Reference Figure 7The third fixing fixture 4 includes a second base 41, a moving assembly 42 and a pipe clamping plate 43. The second base 41 can be selectively connected to one of the plurality of mounting holes on the operating table 1. The moving assembly 42 is disposed on the second base 41. The pipe clamping plate 43 is detachably disposed on the moving assembly 42. The pipe clamping plate 43 has a second limiting groove 431. For example, the number of the second limiting grooves 431 is multiple, and the multiple second limiting grooves 431 are arranged vertically and are opened toward one side of the first fixing fixture 2. The moving assembly 42 can drive the pipe clamping plate 43 to move toward the second fixing fixture 3, so that the second limiting groove 431 positions the brake hard pipe 82.

[0057] In one embodiment, the operating table 1 is a whole piece of aluminum table top with a design thickness of 10 mm, and the operating table 1 can be provided with installation holes at any position according to the assembly requirements of the electronic brake system of different models. In another embodiment, the multiple installation holes on the operating table 1 are arranged in groups, and the positional relationship between each group of installation holes is determined according to the installation structure of the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4. By providing multiple installation holes, the same subassembly device can adapt to the assembly requirements of the electronic brake system of different models, thereby saving the configuration cost of the assembly equipment and saving the layout space of the automobile production line.

[0058] In one embodiment, the assembly process of the electronic brake system is as follows: first, fix the second fixing fixture 3, the first fixing fixture 2 and the third fixing fixture 4 on the mounting holes at the corresponding positions according to the needs of different vehicle models, then take an EPBi81 and position it in the first fixing fixture 2, and then start to assemble the two brake hard pipes 82 of the master cylinder, screw the brake hard pipe 82 of the master cylinder into EPBi81, and then perform the torque tightening and color marking process; then install the other four brake hard pipes 82 in sequence, and after the brake hard pipes 82 are screwed into the corresponding interfaces of EPBi81 in sequence, push the pipe clamping plate 43 of the third fixing fixture 4 to push the other brake hard pipes 82 into the pipe clamping plate 43 to achieve the relative positioning of the brake hard pipe 82 and EPBi81, and then clamp the brake hard pipe 82 into the first limiting groove 321 of the remaining second fixing fixture 3 and install the pipe clamp 83, and finally torque and color mark the brake hard pipe 82 in turn. The structure of the assembled electronic brake system and the subassembly device is as follows Figure 8 shown.

[0059] After the assembly of the brake tube 82 and EPBi81 is completed, the brake tube 82 is first separated from the tube clamp plate 431, and then the positioning of the first fixing fixture 2 on the EPBi81 is released, and finally the brake tube 82 is flapped to separate it from the restriction of the second fixing fixture 3, so that the electronic brake system and the subassembly device can be separated. At this time, the tube clamp 83 and the brake tube 82 are installed together to form a subassembly assembly, so that the subassembly assembly can be easily installed on the automobile body on the assembly line.

[0060] When the electronic brake system of another vehicle model needs to be adapted for assembly, the second fixing fixture 3, the first fixing fixture 2 and the third fixing fixture 4 are first disassembled, and then the second fixing fixture 3, the first fixing fixture 2 and the third fixing fixture 4 are reinstalled on the corresponding mounting holes of the operating table 1 according to the corresponding positions of the new vehicle model. After similar steps, the assembly of the electronic brake system of another vehicle model is completed. The structure of the assembled electronic brake system and the subassembly device is as shown in FIG. Fig. 9 shown.

[0061] In this way, the subassembly device disclosed in the present application can take the motor assembly 811 of EPBi81 as a reference, and adjust the first base 31 of the second fixed tooling 3, the third base 21 of the first fixed tooling 2, the fourth base 23 of the first fixed tooling 2, and the second base 41 of the third fixed tooling 4 on the operating table 1. The precise positions can realize the rapid switching of the subassembly device and complete the positioning of the electronic brake system, thereby realizing the subassembly of the electronic brake systems of multiple vehicle models using the same subassembly device, reducing the number of subassembly devices and space occupancy and alleviating the burden of factory space allocation.

[0062] In some embodiments, the operating table 1 has a ruler (not shown) for determining the installation positions of the second fixing fixture 3 and the third fixing fixture 4 relative to the first fixing fixture 2 , so as to selectively connect them with the corresponding installation holes.

[0063] Specifically, the ruler is marked with scale dimensions on the operating table 1. For example, the ruler is in the form of vertical and horizontal coordinate axes or in the form of a grid. When assembling the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4, the first fixing fixture 2, the second fixing fixture 3 and the third fixing fixture 4 can be assembled on the operating table 1 faster and more accurately according to the requirements of the electronic brake system and with reference to the ruler.

[0064] In some embodiments, reference Figure 6 As shown, the second fixing tool 3 also includes a fixing pin 33 , which is disposed on the first limiting groove 321 and is used to be inserted into the pipe clamp 83 to position the pipe clamp 83 .

[0065] In one embodiment, a fixing pin 33 is provided in the middle of the first limiting groove 321. During subassembly, according to the different opening directions of the positioning groove of the pipe clamp 82, part or all of the brake hard pipe 82 is first assembled on the first limiting groove 321 of the pipe clamp seat 32, and then the pipe clamp 83 is positioned and installed on the brake hard pipe 82 through the fixing pin 33. The pipe clamp 82 can be positioned by abutting against the wall of the pipe clamp seat 32 located in the first limiting groove 321.

[0066] In this way, since the fixing pin 33 is consistent with the fixing position of the pipe clamp 83 when assembled on the vehicle, the possible loosening and displacement of the brake hard pipe 82 on the first limiting groove 321 can be avoided, and the brake hard pipe 82 can be positioned more accurately. After assembly, it can be moved to the vehicle as a whole without the need for secondary adjustment.

[0067] In some embodiments, the tube clamp plate 43 has 2 to 4 second limiting grooves 431 arranged vertically. The second limiting grooves 431 can be precisely adjusted to position the height on the tube clamp plate 43 according to assembly requirements, and the specific number of the second limiting grooves 431 can be determined according to the tooling requirements of different vehicle models. Fig.10 As shown, the number of the second limiting grooves 431 is 2, and during assembly, the brake tubes 82 are vertically divided into two rows and respectively inserted into the second limiting grooves 431. Figure 7 or Fig.12 As shown, the number of the second limiting grooves 431 is 4, and the 4 second limiting grooves 431 can be accurately limited at different heights.

[0068] In this way, the pipe clamping plate 43 with different numbers of second limiting grooves 431 can meet the vertical height assembly requirements of the brake hard pipe 82 of different vehicle models.

[0069] In some embodiments, the third fixing tool 4 further includes a second handle assembly 44 , which is disposed on the second base 41 , and the second handle assembly 44 is connected to the moving component 42 for pushing the pipe clamp plate 43 to move toward the second fixing tool 3 .

[0070] Specifically, after the brake tubes 82 are screwed into the corresponding interfaces of the HCU assembly 812 in sequence, the second handle assembly 44 is pushed to move the mobile assembly 42 toward the second fixed fixture 3 until the brake tube 82 is inserted into the second limiting groove 431, thereby achieving the relative positioning of the brake tube 82 and the EPBi 81. The second handle assembly 44 makes the movement of the mobile assembly more convenient.

[0071] In some embodiments, the moving assembly 42 includes a slide rail 421 and a sliding seat 422, the slide rail 421 is arranged on the second base 41, the sliding seat 422 is slidably connected to the slide rail 421, and the pipe clamp plate 43 is detachably arranged on the sliding seat 422. For example, the connection between the pipe clamp plate 43 and the sliding seat 422 is realized by bolts and nuts. In this way, when assembling electronic brake systems of different models, different pipe clamp plates 43 can be quickly and conveniently replaced, thereby adjusting the number and height positioning of the second limiting groove 431 to adapt to more models. In another embodiment, the moving assembly 42 can also be a gear meshing structure.

[0072] Further, refer to Fig.12The sliding seat 422 includes a sliding groove 422a and a fixed seat 422b. The sliding groove 422a is slidably connected to the slide rail 421. The fixed seat 422b is arranged on the sliding groove 422a. The tube clamping plate 43 is detachably arranged on the fixed seat 422b. Specifically, a through hole is designed on the top of the fixed seat 422b. When in use, a nut is passed through a section of the through hole to lock the tube clamping plate 43 through a thread. In this way, the moving assembly 42 can be further disassembled, and the sliding groove 422a and the slide rail 421 can be replaced in time after being worn, thereby improving the stability of the subpackaging device.

[0073] In some embodiments, the second handle assembly 44 includes a second handle 441 and a handle base 442. The handle base 442 is detachably disposed on the second base 41. The second handle 441 is detachably disposed on the handle base 442 to push the pipe clamp plate 43 toward the second fixing tool 3.

[0074] In some embodiments, reference Fig.11 As shown, the first fixed tooling 2 includes a third base 21, a fixed platform 22, a fourth base 23 and a first handle assembly 24. The fixed platform 22 is arranged on the third base 21. The fixed platform 22 has a conformal groove 221 for positioning the motor assembly 811 of EPBi81; the first handle assembly 24 is arranged on the fourth base 23 for pressing the HCU assembly 812 of EPBi81; the third base 21 and the fourth base 23 are respectively connected to one group of the multiple mounting holes of the operating table 1.

[0075] Since the design structures of the ECU assembly 813 and the HCU assembly 812 of the EPBi81 are generally developed by each company, the structures are different. The motor assembly 811 is basically purchased from a mature motor supplier, and the structure of the motor assembly 811 is basically the same. Therefore, the embodiment of the present application uses the motor assembly 811 as the positioning reference surface, which can realize the positioning of all EPBi81 on the market, and then realize the subassembly of the electronic brake system.

[0076] The specific process of positioning EPBi81 on the first fixed tooling 2 is: first place the motor assembly 811 of EPBi81 on the conformal groove 221, then press down the first handle assembly 24, and together with the fixed platform 22, limit the HCU assembly 812, and at the same time, the motor assembly 811 is also pressed on the conformal groove 221, thereby realizing the positioning of EPBi81.

[0077] In one embodiment, the conformal groove 221 is in the shape of an arc groove, and its curvature is roughly equivalent to the curvature of the circular wall of the mature motor assembly 811 on the market. Furthermore, the conformal groove 221 is made of rubber material. During the assembly process, the motor assembly 811 is pressed on the conformal groove 221 made of rubber material, and the conformal groove 221 deforms under the pressure to better fit the curvature of the circular wall of the motor assembly 811. In this way, the EPBi81 is better adapted to the fixing table 22, while reducing the wear caused by the conformal groove 221 to the motor assembly 811.

[0078] In some embodiments, the first handle assembly 24 includes a first handle 241, a bracket 242, a limiting nut 243, a limiting push rod 244 and a limiting column 245. One end of the first handle 241 and the bracket 242 are respectively connected to the fourth base 23. The limiting push rod 244 is connected to the other end of the bracket 242 through the limiting nut 243. The limiting column 245 is arranged on the limiting push rod 244. The first handle 241 can push the bracket 242 to rotate, so that when the limiting push rod 244 is pressed down, the limiting column 245 can abut against the HCU assembly 812.

[0079] Specifically, in one embodiment, the connection mode of the first handle 241 and one end of the bracket 242 to the fourth base 23 and the connection mode of the limiting push rod 244 to the other end of the bracket 242 through the limiting nut 243 are both rotational connections. When fixing EPBi81, the first handle 241 is rotated to make the bracket 242 rotate downward, thereby making the limiting push rod 244 also move downward, and finally making the limiting column 245 abut against the HCU assembly 812 to achieve fixation. In another embodiment, the first handle 241 and one end of the bracket 242 can slide up and down along the fourth base 23. When fixing EPBi81, the first handle 241 is pushed down to make the bracket 242 and the limiting push rod 244 move downward, and finally making the limiting column 245 abut against the HCU assembly 812 to achieve fixation.

[0080] Furthermore, the material of the limiting column 245 may be rubber, so as to reduce the wear of the HCU assembly 812 by the limiting column 245 when the limiting column 245 abuts against the HCU assembly 812.
