Description

[0003] In the existing technology, the production of automobile brake assist systems mainly adopts manual or semi-automatic assembly methods. With the continuous development and application of intelligent and automated technologies, automated assembly has become a trend in the manufacturing industry with broad prospects and application value. The fully automatic assembly of automobile brake assist systems has also become an effective means for current automobile manufacturers to enhance competitiveness, reduce costs and improve product quality.

[0004] During the inspection process after the automatic assembly of the automobile brake assist system, including the sealing and pressure testing of the oil pot, the oil pot end cover needs to be temporarily sealed. Since the pressure inside the oil pot is high during the inspection process, the sealing performance of the sealing device is required to be high. The traditional sealing mechanism mainly uses continuous external force to squeeze and seal the oil pot end cover. Not only does it require high positioning accuracy between the sealing mechanism and the oil pot, but the sealing force needs to be pre-set, and the operation is relatively cumbersome. It is difficult to achieve rapid sealing detection of the oil pot during the mass production of automobile brake assist systems. Summary of the Invention

DETAILED DESCRIPTION

[0047] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0049] The oil tank blocking mechanism for brake booster system detection provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0050] like Figures 1 to 4 As shown, an embodiment of the present application provides an oil tank sealing mechanism for brake assist system detection, including a clamping jaw frame 110, a sliding shaft 150 is passed through and slidably provided on the clamping jaw frame 110, a groove wheel 180 is rotatably provided on one end of the sliding shaft 150, and a track wheel 130 is fixed on the other side end face.

[0051] A plurality of clamping members 120 are hingedly provided in a circular array on the end surface of the clamping frame 110 close to the groove wheel 180 and about the sliding shaft 150, a guide member 140 is fixedly provided on the end surface of the side away from the groove wheel 180, a handle 100 is fixedly provided on the end surface of the track wheel 130 away from the clamping frame 110, and a sealing gasket 190 is fixedly provided on the end surface of the groove wheel 180 away from the clamping frame 110.

[0052] like Figure 9 As shown, an annular groove 184 is provided on the groove wheel 180 at a position corresponding to the clamping jaw 120, and the clamping jaw 120 can interfere with the groove wall of the annular groove 184 at the corresponding position. When the sliding shaft 150 slides and drives the groove wheel 180 to move, the clamping jaw 120 can rotate to open or tighten under the action of the groove wall track of the annular groove 184.

[0053] Figure 6 As shown, a guide groove 142 is provided on the guide member 140, and the track wheel 130 can interfere with the groove wall of the guide groove 142. When the handle 100 drives the track wheel 130 to rotate, the track wheel 130 can move axially along the sliding shaft 150 under the action of the groove wall track of the guide groove 142, thereby driving the sliding shaft 150 to slide relative to the clamping jaw frame 110.

[0054] like Figure 11As shown, initially, the clamping jaw 120 is in an open state under the action of the wall of the annular groove 184, and the track wheel 130 does not interfere with the wall of the index groove 142. During the inspection, the blocking mechanism is placed at the opening position of the end of the oil pot 200, and at this time, the sealing gasket 190 maintains a certain distance from the opening of the oil pot 200. The operator holds the clamping jaw frame 110 with one hand to keep a certain distance from the opening of the oil pot 200, and presses the handle 100 with the other hand, thereby driving the track wheel 130, the slide shaft 150, the groove wheel 180, and the sealing gasket 190 to move toward the side of the opening of the oil pot 200 relative to the clamping jaw frame 110. During this process The clamping jaw 120 rotates and tightens under the action of the groove wall trajectory of the annular groove 184, thereby clamping the raised pipe at the opening position of the oil pot 200 to achieve automatic centering. When the clamping jaw 120 is clamped, the operator rotates the handle 100, thereby driving the track wheel 130 and the slide shaft 150 to rotate relative to the clamping jaw frame 110 and the groove wheel 180. During this process, the track wheel 130 abuts against the groove wall of the index groove 142 and moves toward the side close to the opening of the oil pot 200 under the action of the groove wall trajectory of the index groove 142, thereby driving the sealing gasket 190 to further press the opening of the oil pot 200 to achieve sealing of the oil pot 200.

[0055] In the embodiment of the present application, the above-mentioned oil pot sealing mechanism for brake assist system detection is adopted, and the annular groove 184 on the groove wheel 180 cooperates with the clamping claw member 120 to realize the positioning of the oil pot 200 opening by the sealing mechanism, and at the same time, the guide groove 142 on the guide member 140 cooperates with the track wheel 130 to realize the pressing and sealing of the oil pot 200 opening by the sealing gasket 190. It is not only simple to operate, but also can ensure the sealing strength and sealing performance of the sealing gasket 190 on the oil pot 200 opening.

[0056] like Figure 2 、 Figure 6 As shown, three guide members 140 are provided on the end surface of the clamping frame 110 away from the clamping member 120 in a circular array about the sliding shaft 150, and the track wheel 130 includes a wheel body 131 fixedly connected to the sliding shaft 150, and three offset pins 132 are fixedly provided on the wheel body 131 in a circular array about the axis of the sliding shaft 150, wherein the three guide members 140 maintain a distance from each other, and the three offset pins 132 can respectively move axially along the sliding shaft 150 at the gap position between the three guide members 140.

[0057] The guide member 140 includes a limit block 141 fixed on the clamping frame 110 and a guide groove 142 provided on the end face of the limit block 141 close to the clamping frame 110, wherein the guide groove 142 includes an arc segment and a locking flat segment, and the locking flat segment of the guide groove 142 is parallel to the inner wall of the side of the clamping frame 110 and the corresponding side end face of the clamping frame 110. In the direction from the handle 100 to the groove wheel 180, the arc segment of the guide groove 142 is connected with the counterclockwise end face of the limit block 141. At the same time, along the counterclockwise direction from the handle 100 to the groove wheel 180, the distance between the arc segment of the guide groove 142 and the inner wall of the side of the clamping frame 110 and the corresponding side end face of the clamping frame 110 gradually decreases until it is aligned with the locking flat segment of the guide groove 142.

[0058] When the operator presses down the handle 100 to rotate and tighten the clamping jaw 120 , the offset pin 132 moves axially along the sliding shaft 150 in the gap between the three guide members 140 and is located at a position corresponding to the arc segment of the guide groove 142 .

[0059] It can be understood that, in the direction from the handle 100 to the groove wheel 180, when the operator rotates the handle 100 counterclockwise, the track wheel 130 rotates counterclockwise, and the offset 132 and the inner wall of the index groove 142 close to the clamping jaw frame 110 are interfered with. Under the interference of the arc segment of the index groove 142, the track wheel 130 will move toward the side close to the clamping jaw member 120. When the offset 132 moves to the locking flat section of the index groove 142, the locking flat section of the index groove 142 close to the inner wall of the clamping jaw frame 110 can interfere with the offset 132 and limit the movement of the track wheel 130 in the direction away from the clamping jaw member 120.

[0060] In an embodiment of the present application, the above-mentioned oil pot sealing mechanism for brake assist system detection is adopted, and the arc segment of the indexing groove 142 is used to drive the track wheel 130 and the sealing gasket 190 to move to press the opening of the oil pot 200. At the same time, the locking flat section of the indexing groove 142 is used to ensure the unidirectionality of the pressing process of the sealing gasket 190, thereby preventing the sealing gasket 190 from loosening under the reaction force at the end of the oil pot 200, thereby ensuring the sealing reliability and sealing performance of the oil pot 200.

[0061] It is understandable that the number of guide members 140 and offset members 132 is not limited to the above-mentioned number. However, in order to ensure uniform force, at least two guide members 140 and corresponding offset members 132 are required.

[0062] It can be understood that the setting direction of the guide groove 142 is not limited to the above-mentioned one. Specifically, the setting direction of the guide groove 142 determines the rotation direction of the handle 100 when the operator drives the sealing gasket 190 to seal the opening of the oil can 200 by rotating the handle 100. Therefore, as long as the setting form of the arc segment and the locking flat segment of the guide groove 142 is guaranteed, there is no specific restriction on its setting direction on the limit block 141.

[0063] In a preferred embodiment, as Figure 3 、 Figure 7 As shown, the clamping jaw frame 110 includes a mounting plate 111 fixedly connected to the guide member 140, and a center hole 113 is provided on the mounting plate 111 for sliding connection with the sliding shaft 150. Three hinged rods 112 are fixedly provided in a circular array about the center hole 113 on the end surface of the mounting plate 111 away from the handle 100, and the clamping jaw member 120 is hingedly arranged on the end of the hinged rod 112 away from the mounting plate 111.

[0064] In a preferred embodiment, as Figure 8 As shown, the clamping jaw member 120 includes a clamping jaw body 121, on which a hinged ear 124 hinged to the hinged rod 112 is fixedly provided, and a clamping portion 125 for clamping the protruding pipe at the opening of the oil pot 200 is fixedly provided at the end of the clamping jaw body 121 away from the handle 100, and a sliding portion 122 capable of abutting against the groove wall of the annular groove 184 on the groove wheel 180 is fixedly provided at the end of the clamping jaw body 121 close to the handle 100, and a travel groove 123 is passed through the sliding portion 122, and the hinged rod 112 is located in the travel groove 123 at the corresponding position and is slidably connected to the travel groove 123.

[0065] like Figure 9 As shown, the sheave 180 includes a rotating wheel body 181, and an annular groove 184 is provided on the outer circumferential surface of the wheel body 181. In the direction from the sealing gasket 190 to the handle 100, the groove depth of the annular groove 184 gradually decreases until it is flush with the outer circumferential surface of the wheel body 181.

[0066] It can be understood that the annular groove 184 can also be set on both axial sides of the sliding shaft 150, and its groove depth gradually decreases until it is flush with the outer cylindrical surface of the wheel body 181, that is, as long as it is ensured that in the direction from the sealing gasket 190 to the handle 100, the groove depth of at least one section of the annular groove 184 gradually decreases until it is flush with the outer cylindrical surface of the wheel body 181.

[0067] It can be understood that when the operator presses the handle 100 to make the groove wheel 180 move relative to the clamping jaw frame 110 and the clamping jaw member 120 toward the side close to the opening of the oil pot 200, the sliding portion 122 gradually moves from the bottom of the groove in the annular groove 184 to abut against the outer cylindrical surface of the wheel body 181, and the clamping jaw member 120 rotates. The sliding portion 122 moves toward the side away from the axis of the sliding shaft 150, and the clamping portion 125 moves toward the side close to the axis of the sliding shaft 150, thereby realizing the clamping and positioning of the protruding pipe of the oil pot 200 opening by the clamping jaw member 120. During this process, the hinged rod 112 slides in the travel groove 123, and the rotation guidance and limitation of the clamping jaw member 120 are realized through the travel groove 123.

[0068] In an embodiment of the present application, the above-mentioned oil pot sealing mechanism for brake assist system detection is adopted, and the opening and tightening of the clamping member 120 are controlled by the relative movement of the groove wheel 180 and the clamping member 120 and the change in the groove depth of the annular groove 184. The entire process is completely based on the operator's pressing control of the handle 100, and the operation is simple. Moreover, when the clamping member 120 abuts against the outer cylindrical surface of the wheel body 181, it has a certain limiting effect on the rotation of the clamping member 120, further ensuring the positioning stability of the sealing mechanism.

[0069] In a preferred embodiment, as Figure 3 、 Figure 10 As shown, the sliding shaft 150 includes an axis body 151 that is slidably connected to the clamping jaw frame 110, and a limiting plate 152 is fixedly provided on the end surface of the axis body 151 away from the handle 100. The limiting plate 152 is provided on the end surface away from the handle 100 with a first rolling groove 153 for accommodating the ball 170.

[0070] like Figure 9 As shown, the groove wheel 180 also includes a first embedding groove 182 arranged on the end face of the wheel body 181 close to the handle 100, and a limiting groove 186 for accommodating the limiting plate 152 is provided on the bottom wall of the first embedding groove 182, and a second rolling groove 183 for accommodating the ball 170 is provided on the bottom wall of the limiting groove 186.

[0071] like Figure 3 、 Figure 4 As shown, the cover plate 160 is fixedly embedded in the first embedding groove 182, the shaft 151 and the cover plate 160 are connected in rotation, the limiting plate 152 is connected in rotation in the limiting groove 186, the first rolling groove 153 and the second rolling groove 183 correspond in position and engage with each other to form an annular raceway, and a plurality of balls 170 are rolled in the annular raceway formed by the first rolling groove 153 and the second rolling groove 183.

[0072] In an embodiment of the present application, the above-mentioned oil pot sealing mechanism for brake assist system detection is adopted, and a ball 170 is set between the clamping claw 120 and the groove wheel 180 to reduce the rotational friction between the two, thereby avoiding the influence of the rotation of the track wheel 130 and the sliding shaft 150 on the position of the sealing gasket 190 after the sealing gasket 190 seals the opening of the oil pot 200, thereby further improving the sealing stability of the sealing gasket 190 on the oil pot 200.

[0073] In a preferred embodiment, as Figure 9 As shown, the sheave 180 further includes a second embedding groove 185 provided on the end surface of the wheel body 181 away from the handle 100 , and the sealing gasket 190 is fixedly embedded in the second embedding groove 185 .

[0074] It is understandable that the fixing method of the sealing gasket 190 on the groove wheel 180 is not limited to the above-mentioned one. At the same time, the sealing gasket 190 is made of elastic material, so that when the handle 100 is turned to drive the sealing gasket 190 to press the opening of the oil pot 200, the sealing gasket 190 has a certain extensibility, fully covering the opening of the oil pot 200, thereby ensuring the sealing effect.

[0075] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
