DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Before further describing the embodiments of the present invention in detail, the directional nouns involved in the embodiments of the present invention, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the protection scope of the present invention.

[0048] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0049] Figure 1 It is a schematic diagram of the existing brake main control; Figure 2 is a schematic diagram of a disassembly device according to an embodiment of the present invention from an angle; Figure 3 FIG. 1 is a schematic diagram from another angle of a disassembly device according to an embodiment of the present invention.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a disassembly device 100 for a brake master control housing, wherein the brake master control housing 200 includes a lower aluminum housing 210 and an upper plastic housing 220 connected to each other, wherein the upper plastic housing 220 is provided with a first bolt through hole 221, wherein a bolt is provided in the first bolt through hole 221, and the upper plastic housing 220 is fixedly connected to the brake master cylinder by bolts, and the disassembly device 100 includes:

[0051] Support frame 110;

[0052] The lower fixing member 120 is movably connected to the support frame 110. The lower fixing member 120 has a slot 123, which is sleeved on the lower aluminum shell 210. The slot 123 is adapted to the shape of the lower aluminum shell 210.

[0053] An upper fixing member 130, the upper fixing member 130 is fixedly connected to the upper plastic shell 220 by bolts, and the upper fixing member 130 is located above the lower fixing member 120;

[0054] The stretching member 140 is disposed on the support frame 110 . The stretching member 140 is fixedly connected to the upper fixing member 130 . The stretching member 140 is configured to drive the upper fixing member 130 to approach or move away from the lower fixing member 120 .

[0055] The disassembling device 100 includes a support frame 110 for supporting and fixing a lower fixing member 120 and a stretching member 140 . The lower fixing member 120 is used to fix the lower aluminum shell 210 . The stretching member 140 is fixedly connected to the upper fixing member 130 . The upper fixing member 130 is fixedly connected to the upper plastic shell 220 . During disassembly, first fix the lower aluminum shell 210 to the lower fixing piece 120, then fix the upper fixing piece 130 to the upper aluminum shell, fix the lower fixing piece 120 to the support frame 110, move the stretching piece 140 downward to be fixedly connected to the upper fixing piece 130, and then control the stretching piece 140 to move upward. At this time, the lower fixing piece 120 and the lower aluminum shell 210 are already fixed, and the upper fixing piece 130 and the upper plastic shell 220 are pulled upward by the stretching piece 140, and a tensile force is applied between the lower aluminum shell 210 and the upper plastic shell 220 to separate the adhesive between the lower aluminum shell 210 and the upper plastic shell 220, thereby realizing the separation of the lower aluminum shell 210 and the upper plastic shell 220 without causing deformation of the lower aluminum shell 210 and the upper plastic shell 220, so as to facilitate the reconnection of the lower aluminum shell 210 and the upper plastic shell 220 through adhesive, thereby reducing the maintenance cost of the ABS pump and improving the economy of ABS pump maintenance.

[0056] Specifically, the slot 123 of the lower fixing member 120 matches the lower aluminum shell 210, so that the slot 123 of the lower fixing member 120 can be closely fitted with the lower aluminum shell 210 to achieve a fixed connection between the lower fixing member 120 and the lower aluminum shell 210, and then the lower fixing member 120 is fixedly connected to the support frame 110 to ensure that the lower aluminum shell 210 is fixed. Then, the tension member 140 moves downward, driving the upper fixing member 130 fixedly connected to the tension member 140 to move downward until the upper fixing member 130 fits with the upper plastic shell 220, and bolts are sequentially passed through the tension member 140, the upper fixing member 130 and the upper plastic shell 220 to achieve a fixed connection between the upper fixing member 130 and the tension member 140. Then, the stretching member 140 is controlled to move upward, and a tensile force is applied between the lower aluminum shell 210 and the upper plastic shell 220 until the adhesive between the lower aluminum shell 210 and the upper plastic shell 220 is broken, so as to separate the lower aluminum shell 210 and the upper plastic shell 220, and to maintain or upgrade the main control board of the electric control unit inside. Then, the upper plastic shell 220 and the lower aluminum shell 210 can be reinstalled, and the upper plastic shell 220 and the lower aluminum shell 210 can be resealed to achieve the secondary sealing of the lower aluminum shell 210 and the upper plastic shell 220, so as to avoid prying the lower aluminum shell 210 and the upper plastic shell 220 with a screwdriver, causing the contact position of the lower aluminum shell 210 and the upper plastic shell 220 to deform, affecting the secondary sealing, and improving the reliability of the secondary sealing of the lower aluminum shell 210 and the upper plastic shell 220. At the same time, compared with direct replacement, the main control board inside can be repaired and upgraded, reducing the maintenance and repair costs and improving the economy.

[0057] It is understandable that the upper fixing member 130 can be fixed to the upper plastic shell 220 first and then fixedly connected to the stretching member 140. Alternatively, the stretching member 140 can be fixed to the upper fixing member 130 first, and then the stretching member 140 is moved downward to fit the upper plastic shell 220, and then the upper fixing member 130 and the upper plastic shell 220 are fixedly connected. Both methods can achieve fixed connection between the upper fixing member 130 and the upper plastic shell 220.

[0058] Figure 6 Schematic diagram of a support frame according to an embodiment of the present invention.

[0059] In a possible implementation, Figure 6 As shown, the support frame 110 includes:

[0060] The bottom plate 111, the lower fixing member 120 is connected to the bottom plate 111;

[0061] The top plate 112 is disposed above the bottom plate 111, and the tension member 140 is connected to the top plate 112;

[0062] Columns 113, a plurality of columns 113 are disposed between the top plate 112 and the bottom plate 111;

[0063] The lower fixing member 120 is connected to the bottom plate 111 , and the stretching member 140 is connected to the top plate 112 .

[0064] It should be noted that the support frame 110 includes a bottom plate 111 and a top plate 112, and a column 113 supporting the bottom plate 111 and the top plate 112. The distance between the top plate 112 and the bottom plate 111 is within the telescopic length range of the stretching member 140, that is, the distance between the top plate 112 and the bottom plate 111 is not greater than the sum of the thickness of the brake main control housing 200 and the telescopic length of the stretching member 140, so as to ensure the effective stretching of the stretching member 140. In this embodiment, the connection between the column 113 and the top plate 112 and the bottom plate 111 can be a welding connection, or the column 113 can be inserted into the top plate 112 and the bottom plate 111, that is, through holes are set in the top plate 112 and the top plate 112, and the column 113 is inserted into the through hole after cold pressing, so as to realize the connection between the column 113 and the top plate 112 and the bottom plate 111 respectively.

[0065] It is understandable that there are at least three columns 113 to ensure the stability of the support for the top plate 112 and the bottom plate 111. Four columns 113 can also be provided to maximize the reliability of the support for the top plate 112 and the bottom plate 111 by the columns 113 while ensuring the feasibility of fixing the lower fixing member 120 to the bottom plate 111. More than four columns 113 can also be provided to increase the stability of the support, but this will affect the convenience of fixing the lower fixing member 120 to the bottom plate 111 and will also increase the cost. Therefore, in this embodiment, four columns 113 are selected to support the top plate 112 and the bottom plate 111.

[0066] In a feasible implementation manner, the bottom plate 111 includes:

[0067] The support plate 1111 is arranged parallel to the top plate 112;

[0068] The slideway is fixedly connected to the support plate 1111 , and the lower fixing member 120 slides to the bottom of the upper fixing member 130 through the slideway.

[0069] The bottom plate 111 includes a support plate 1111 and a slideway disposed on the support plate 1111. The support plate 1111 is disposed in parallel with the top plate 112 to ensure uniformity and stability of the stretching of the stretching member 140. The slideway is disposed to facilitate the lower fixing member 120 to move in a certain direction, that is, to have a certain limiting effect on the lower fixing member 120, ensuring that the lower aluminum shell 210 on the lower fixing member 120 can be aligned with the upper fixing member 130.

[0070] In a feasible implementation manner, the slide includes: a first slide 1112 and a second slide 1113 arranged opposite to each other, the first slide 1112 and the second slide 1113 have the same structure, and the first slide 1112 includes:

[0071] A horizontal plate, arranged parallel to the supporting plate 1111;

[0072] The vertical plate is arranged perpendicular to the horizontal plate, and the vertical plate is fixedly connected to the support plate 1111;

[0073] The transverse plate of the first slide 1112 and the transverse plate of the second slide 1113 are arranged opposite to each other, and the space enclosed by the transverse plate, the support plate 1111 and the vertical plate forms the slide.

[0074] It should be noted that, through the arrangement of the horizontal plate and the vertical plate, the horizontal plate, the support plate 1111 and the vertical plate enclose a space, that is, a slideway is formed, which limits the specific position of the lower fixing member 120, so that the center line of the lower fixing member 120 can coincide with the axis of the tensile member 140, thereby ensuring the uniformity and reliability of the tensile force.

[0075] It is understandable that the horizontal plate and the vertical plate can be integrally formed, that is, L-shaped, so that the L-shaped vertical plate is fixedly connected to the support plate 1111. Alternatively, the horizontal plate and the vertical plate can be produced separately, and then the horizontal plate is located above the vertical plate, and bolts are sequentially passed through the horizontal plate, the vertical plate and the support plate 1111 to achieve the fixed connection between the first slide 1112 and the second slide 1113 and the support plate 1111.

[0076] For example, an insertion slot can be provided on the horizontal plate, and the insertion slot is located at both ends of the length direction of the horizontal plate. The opening of the insertion slot on the horizontal plate of the first slide 1112 is arranged opposite to the opening of the insertion slot on the horizontal plate of the second slide 1113. The plug-in plate can be inserted into the insertion slot to further fix the lower fixing member 120, improve the stability of the lower fixing member 120, and avoid the stretching of the tensile member 140, so that the lower fixing member 120 moves in the slideway, affecting the stability and uniformity of the tensile force of the tensile member 140. In other words, the positioning of the lower fixing member 120 in the X direction is achieved by the vertical plate, the positioning of the lower fixing member 120 in the Y direction is achieved by the plug-in plate, and the positioning of the lower fixing member 120 in the Z direction is achieved by the horizontal plate, so as to ensure the stability of the fixing of the lower fixing member 120. The center of the accommodating space of the lower fixing member 120 enclosed by the plug plate and the vertical plate is on the same axis as the center of the upper fixing member 130, that is, the center of the lower fixing member 120 and the center of the upper fixing member 130 are on the same axis, ensuring the uniformity and reliability of the tensile force of the tensile member 140.

[0077] It is understandable that when the plug plate needs to be positioned, the length of the first slideway 1112 and the length of the second slideway 1113 should be longer than the Y-direction length of the lower fixing member 120, so as to ensure that the plug plate and the vertical plate fix the lower fixing member 120 in one position. Figure 2 Without using the plug plate, the lower fixing member 120 can be fixed only by the first slide 1112 and the second slide 1113. As the tensile member 140 is pulled upward, the tensile force generated can create a mutual resistance between the lower fixing member 120 and the horizontal plate, and can also ensure the stability of the lower fixing member 120 and prevent the lower fixing member 120 from moving.

[0078] Figure 4 Schematic diagram of a lower fixing member according to an embodiment of the present invention.

[0079] In a possible implementation, Figure 4 As shown, the lower fixing member 120 includes:

[0080] A first fixing member 121, wherein the first fixing member 121 is provided with a first groove 1231;

[0081] A second fixing member 122, wherein a second groove 1232 is formed on the second fixing member 122;

[0082] Among them, the first groove 1231 and the second groove 1232 form a card slot 123, a second bolt through hole 124 is provided on the side of the first fixing member 121 facing the second fixing member 122, and a bolt blind hole is provided on the side of the second fixing member 122 facing the first fixing member 121; or a second bolt through hole 124 is provided on the side of the second fixing member 122 facing the first fixing member 121, and a bolt blind hole is provided on the side of the first fixing member 121 facing the second fixing member 122.

[0083] It should be noted that the lower fixing member 120 is in a combined form, that is, the lower fixing member 120 includes a first fixing member 121 and a second fixing member 122. The lower aluminum shell 210 is clamped by the first fixing member 121 and the second fixing member 122, thereby improving the reliability of the fixed connection between the lower fixing member 120 and the lower aluminum shell 210. Among them, the first fixing member 121 is provided with a first groove 1231, and the second fixing member 122 is provided with a second groove 1232. After the first fixing member 121 and the second fixing member 122 are combined together, the first groove 1231 and the second groove 1232 are combined into a clamping groove 123. The shape of the clamping groove 123 is the same as the outer edge shape of the lower aluminum shell 210, that is, the lower aluminum shell 210 is completely fitted with the clamping groove 123, thereby improving the contact area between the first fixing member 121 and the second fixing member 122 and the lower aluminum shell 210, thereby improving the reliability of the clamping and fixing of the first fixing member 121 and the second fixing member 122.

[0084] It can be understood that one side of the first fixing member 121 and the second fixing member 122 is provided with a second bolt through hole 124, and the other side is provided with a bolt blind hole, so that the first fixing member 121 and the second fixing member 122 are fixedly connected by bolts, and the fit between the first fixing member 121 and the second fixing member 122 can be slightly adjusted according to the screw-in depth of the bolts, thereby improving the reliability of the first fixing member 121 and the second fixing member 122 clamping the lower fixing member 120.

[0085] For example, the lower aluminum shell 210 in the brake main control housing 200 has a special shape, so the lower fixing member 120 can be prepared by casting, which can ensure the tightness of the card slot 123 and the outer edge of the lower aluminum shell 210, and also help to reduce the production cost of the lower fixing member 120 and improve economic efficiency. After the lower fixing member 120 is prepared, it is cut into a first fixing member 121 and a second fixing member 122, and the second bolt through hole 124 and the bolt blind hole are drilled.

[0086] In a feasible implementation, a first step 125 is provided on the side of the first fixing member 121 facing away from the second fixing member 122, and a second step 126 is provided on the side of the second fixing member 122 facing away from the first fixing member 121. Both the first step 125 and the second step 126 match the slideway.

[0087] In order to match the first slideway 1112 and the second slideway 1113, a first step 125 is provided on the side of the first fixing member 121 away from the second fixing member 122, and a second step 126 is provided on the side of the second fixing member 122 away from the first fixing member 121. The first step 125 matches the first slideway 1112, that is, the first step 125 can move in the space enclosed by the horizontal plate, the support plate 1111 and the vertical plate of the first slideway 1112, and similarly, the second step 126 can also move in the space enclosed by the horizontal plate, the support plate 1111 and the vertical plate of the second slideway 1113.

[0088] It should be noted that, by cooperating between the first step 125 and the first slide 1112 , and the second step 126 and the second slide 1113 , the bottom plate 111 can fix and limit the lower fixing member 120 , thereby ensuring the reliability of the stretching of the stretching member 140 .

[0089] In a feasible embodiment, the stretching member 140 includes

[0090] A telescopic cylinder, the fixed portion of which is fixedly connected to the top plate 112, the telescopic end 142 of the telescopic cylinder passes through the top plate 112, and the telescopic end 142 is located between the top plate 112 and the bottom plate 111, and the telescopic end 142 can be telescoped within the fixed end 141;

[0091] The lifting plate 143 is fixedly connected to one end of the telescopic end 142 away from the fixed end 141 , and the lifting plate 143 is fixedly connected to the upper fixing member 130 .

[0092] Among them, the stretching member 140 is usually a telescopic cylinder, which can be a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod, which can realize the reciprocating movement of the telescopic end 142 in the fixed end 141. A lifting plate 143 is fixedly provided on the end of the telescopic end 142 away from the fixed end 141, and the telescopic end 142 and the lifting plate 143 can be welded. A through hole can also be set in the center of the lifting plate 143, and the telescopic end 142 is cold pressed into the through hole. Alternatively, the telescopic end 142 is tapped to form an external thread, and then a bolt hole is set in the center of the lifting plate 143, and the lifting plate 143 and the telescopic end 142 are connected by threads. In this embodiment, cold pressing is adopted to achieve the fixed connection between the telescopic end 142 and the lifting plate 143.

[0093] It should be noted that by fixing the lifting plate 143 to the upper fixing member 130, the contact area between the tensile member 140 and the upper fixing member 130 can be increased, and the balance and stability of the tensile force of the tensile member 140 can be improved. At the same time, the connection between the lifting plate 143 and the upper fixing member 130 is achieved through multiple holes, which also ensures the reliability and stability of the connection of the upper fixing member 130.

[0094] Figure 5 Schematic diagram of an upper fixing member according to an embodiment of the present invention.

[0095] In a possible implementation, Figure 5 As shown, the upper fixing member 130 is in the shape of a rectangular parallelepiped, and a square groove 131 is provided at the center of the upper fixing member 130, the opening of the square groove 131 faces one side of the lower fixing member 120, and third bolt through holes 132 are provided at the four corners of the upper fixing member 130. Bolts are passed through the lifting plate 143, the third bolt through hole 132 and the first bolt through hole 221 to achieve fixed connection among the lifting plate 143, the upper fixing member 130 and the upper plastic shell 220.

[0096] The upper fixing member 130 is in the shape of a rectangular parallelepiped, and a square groove 131 is provided at the center of the inner part of the rectangular parallelepiped, the opening of the square groove 131 faces downward, and a third bolt through hole 132 is provided at the position corresponding to the first bolt through hole 221 of the upper plastic shell 220, so that the upper fixing member 130 and the upper plastic shell 220 can be fixedly connected by passing the bolt through the first bolt through hole 221 and the second bolt through hole 124. At the same time, the provision of the square groove 131 can, on the one hand, reduce the weight of the upper fixing member 130 and increase the power of the stretching member 140 to stretch, and on the other hand, after the upper plastic shell 220 and the upper fixing member 130 are fitted and fixedly connected, the space of the square groove 131 and the upper plastic shell 220 will form a vacuum adsorption force, further improving the stability and reliability of the connection between the upper fixing member 130 and the upper plastic shell 220.

[0097] In a feasible implementation manner, the lower fixing member 120 and the upper fixing member 130 are made of aviation aluminum.

[0098] Among them, the lower fixing part 120 and the upper fixing part 130 are made of aviation aluminum. Aviation aluminum has the characteristics of light weight but high strength, which can meet the requirements of support and pulling. At the same time, aviation aluminum has a certain ductility and can absorb part of the tensile force. This can further avoid deformation of the lower aluminum shell 210 and the upper plastic shell 220 and ensure the reliability of secondary packaging.

[0099] In a feasible implementation manner, the support frame 110 is made of stainless steel.

[0100] Among them, various components of the support frame 110 are made of stainless steel, that is, the top plate 112, the bottom plate 111 and the columns 113 are all made of stainless steel, which can improve the stability of the support frame 110 and extend the service life of the support frame 110.

[0101] It can be understood that the secondary packaging of the upper plastic shell 220 and the lower aluminum shell 210 can also use the disassembly device 100 of the present application. At this time, the lower aluminum shell 210 is clamped by the lower fixing member 120 and then pushed into the slide. After the upper plastic shell 220 is fixed with the upper fixing member 130 and the lifting plate 143, the telescopic end 142 of the telescopic cylinder extends downward, driving the upper plastic shell 220 to move toward the lower aluminum shell 210, until the upper plastic shell 220 is clamped with the lower aluminum shell 210, and then the upper plastic shell 220 and the lower aluminum shell 210 are sealed by sealant.

[0102] In the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
