Description

Technical Field

[0001] The present application relates to the technical field of brake system boxes, and more particularly to a brake system box and an ultrasonic welding device for manufacturing the brake system box. Background Art

[0002] In modern automobile manufacturing, as a key component, the integrated electronic brake system box is usually configured on the chassis of the vehicle. This location selection takes into account both the functional requirements of the system and the overall layout and space design of the vehicle. However, the integrated electronic brake system box generates a large amount of heat during operation, which poses a potential threat to the stability and lifespan of the system.

[0003] To achieve the dual goals of heat dissipation and waterproofing, engineers have ingeniously installed a waterproof breathable membrane on the ventilation holes of the brake system box. This membrane material not only has good breathability, ensuring effective heat dissipation of the system box during normal operation, but also its waterproof property can effectively prevent external moisture from entering the system, thus avoiding system failures or damages caused by water wading and other reasons. In the current field of automobile manufacturing, for the installation method of the waterproof breathable membrane, the traditional process of gluing is mostly adopted. Specifically, a specific adhesive is used to firmly bond the waterproof breathable membrane at the position of the ventilation hole.

[0004] However, the gluing method also exposes some problems in practical applications. The most prominent one is its limited ability to withstand water pressure. According to tests, the waterproof breathable membrane installed by the gluing method can usually only withstand a water pressure of about 25 kPa. This means that when facing a large water pressure, the membrane material may rupture or fall off due to being unable to bear it, resulting in the failure of the waterproof performance of the system box. This will not only seriously affect the normal operation of the integrated electronic brake system but also pose a potential threat to driving safety, indicating that there is room for improvement. Summary of the Invention

[0005] The purpose of the present application is to provide a brake system box and an ultrasonic welding device for manufacturing the brake system box, so as to solve the problem that the waterproof breathable membrane in the above related technologies has poor water pressure resistance, affecting the waterproof performance of the system box.

[0006] In the first aspect, a brake system box provided by the present application adopts the following technical solution:

[0007] A braking system box includes a box body and a breathable and waterproof structure provided on the box body. The box body includes a bottom plate and side plates. The breathable and waterproof structure includes breathable holes provided on the bottom plate, a convex edge surrounding the breathable holes on the bottom plate, and a waterproof and breathable membrane ultrasonically welded to a base material. The welding area between the waterproof and breathable membrane and the base material covers the position of the convex edge. The cross-section of the convex edge gradually narrows in width away from the bottom plate. A retaining ring surrounding the breathable holes and the convex edge is provided on the base material.

[0008] By adopting the above technical solution, the anti-hydrostatic pressure ability is improved by ultrasonic welding between the waterproof and breathable membrane and the bottom plate. Secondly, a convex edge is provided within the coverage of the welding area in a circle. The convex edge makes the heat concentrate at the position of the convex edge during ultrasonic welding, and when the melted material combines with the waterproof and breathable membrane, a connection structure with a more tightly connected circle can be formed, enabling the anti-hydrostatic pressure ability to be increased from 50 kPa of conventional ultrasonic welding to more than 70 kPa.

[0009] In a second aspect, a technical solution adopted by an ultrasonic welding device for producing a braking system box provided in this application is as follows:

[0010] An ultrasonic welding device for producing a braking system box includes a base, a rotating disk provided on the base, and a driving member for driving the rotating disk to rotate. A limiting groove for placing the braking system box is provided on the rotating disk. A support crossbeam is fixedly provided on the base, and a welding head located above the limiting groove on the rotating disk and a power member for driving the welding head to move up and down are provided on the support crossbeam.

[0011] By adopting the above technical solution, an ultrasonic welding device is used to install and fix the waterproof and breathable membrane, so as to make the waterproof and breathable membrane fixed on the bottom plate more firm and improve the anti-hydrostatic pressure ability of the waterproof and breathable membrane.

[0012] Optionally, a plurality of universal wheels with foot brakes are fixedly provided on the bottom side surface of the base, and traction handles are provided on two opposite side surfaces of the base.

[0013] By adopting the above technical solution, when the ultrasonic welding device needs to be moved a short distance, the ultrasonic welding device can be pulled by the traction handle, and it slides on the ground through the universal wheels. After the position adjustment is completed, the universal wheels are locked, which is convenient for realizing the short-distance movement of the device.

[0014] Optionally, a support rod is slidably arranged in the vertical direction on the side of the base near the traction handle. An adjusting rod is fixedly arranged on the outer periphery of the support rod away from the base. A guiding inclined surface is arranged on the edge of the end of the adjusting rod away from the support rod. The traction handle is hinged to the side of the base. A positioning rod capable of rotating above the adjusting rod along the guiding inclined surface is fixedly arranged on the traction handle. The positioning rod can abut against the upper side surface of the adjusting rod and make the lower end of the support rod abut against the ground.

[0015] By adopting the above technical solution, when the user rotates the traction handle upward until the lower side surface of the positioning rod abuts against the upper side surface of the adjusting rod, the adjusting rod can be squeezed downward, and then the lower end of the support rod abuts against the ground, so as to improve the installation stability of the base in this state.

[0016] Optionally, an elastic pad is fixedly arranged on the lower end of the support rod.

[0017] By adopting the above technical solution, when the support rod moves downward, the elastic pad on the support rod abuts against the ground, so as to reduce the possibility of wear when the support rod abuts against the ground and extend the service life of the support rod.

[0018] Optionally, a limiting plate is fixedly arranged on the outer peripheral surface of the support rod. A receiving plate located directly below the limiting plate is fixedly arranged on the side of the base. A spring in a compressed state is fixedly arranged on the upper side surface of the receiving plate. The other end of the spring is fixedly connected to the bottom side of the limiting plate.

[0019] By adopting the above technical solution, when the positioning rod on the traction handle rotates above the adjusting rod, the compression spring is squeezed, and the whole support rod moves downward in the vertical direction, and the lower end of the support rod abuts against the ground. When the traction handle rotates downward and is misaligned with the adjusting rod, the extrusion of the spring is released. At this time, the spring resets and squeezes the limiting plate, so that the support rod maintains the force of moving upward vertically. There is a gap between the bottom side of the support rod and the ground in this state and it does not abut against the ground, which is convenient for short-distance movement of the ultrasonic welding equipment.

[0020] Optionally, a protective cover made of flexible material is fixedly arranged on the side of the support cross beam facing the base. A fixing ring is fixedly arranged on the outer periphery of the lower edge of the protective cover. The protective cover can be unfolded towards the base and sleeved on the outer periphery of the rotating disc. The protective cover can be folded and stored under the support cross beam. A locking member capable of locking the fixing ring is arranged on the base. When the support rod slides downward, it can drive the locking member to unlock the fixing ring in the locked state.

[0021] By adopting the above technical solution, when the device is not in use, the protective cover can be unfolded towards the direction close to the base and sleeved on the outer periphery of the rotating disk, thereby protecting the welding head and the rotating disk and reducing the possibility of external dust or other impurities adhering to the welding head and the rotating disk; when in use, the protective cover can be folded upwards and stored under the bottom side of the support cross beam.

[0022] Optionally, the locking member includes a hinge seat fixedly arranged on the upper side surface of the base, a locking rod hinged to the hinge seat in the middle, a locking convex block fixedly arranged on the outer periphery of one end of the locking rod, and the fixing ring can be placed into the gap between the locking convex block and the base; an extension rod extending above the base is fixedly arranged at the upper end of the support rod, and the upper end of the extension rod abuts against the bottom side of the end of the locking rod away from the locking convex block, and a torsion spring for tightly abutting the upper end of the extension rod against the bottom side of the locking rod is arranged in the hinge seat.

[0023] By adopting the above technical solution, when the extension rod slides upwards, it presses the bottom side of the locking plate, causing the locking convex block to rotate towards the direction close to the base, and the fixing ring abutting against the upper side surface of the base can be tightly locked, enhancing the protective performance of the protective cover; when the extension rod slides downwards, the torsion spring acts on the locking rod, causing the locking convex block to rotate away from the base, releasing the tight locking of the fixing ring abutting against the upper side surface of the base, facilitating the subsequent folding and storage of the protective cover.

[0024] Optionally, a storage ring groove for the protective cover to be folded and placed is formed on the side surface of the support cross beam facing the substrate, an elastic clamping member is arranged on the outer periphery of the fixing ring, and a first positioning groove for the elastic clamping member to be inserted into is formed on the inner wall of the storage ring groove.

[0025] By adopting the above technical solution, when the protective cover is adjusted to the storage state, the staff needs to fold the protective cover upwards, place the fixing ring into the storage ring groove, and at the same time make the protruding part of the arc-shaped convex block snap into the first positioning groove, so as to facilitate the folding and storage of the protective cover.

[0026] Optionally, a locking snap ring is fixedly arranged on the base, the fixing ring can be sleeved on the outer periphery of the locking snap ring, and a second positioning groove for the elastic clamping member to be inserted into is formed on the outer periphery of the locking snap ring.

[0027] By adopting the above technical solution, when the protective cover is unfolded downwards, the fixing ring can be sleeved on the outer periphery of the locking snap ring, and at the same time the elastic clamping member on the fixing ring is inserted into the corresponding second positioning groove, thereby improving the stability when the fixing ring abuts against the upper side surface of the base.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The waterproof and breathable membrane and the bottom plate are ultrasonically welded to improve the water pressure resistance. Secondly, a convex edge is provided within the coverage of the welding area. The convex edge makes the heat concentrate at the position of the convex edge during ultrasonic welding, and when the melted material combines with the waterproof and breathable membrane, a more tightly connected structure can be formed in a circle, enabling the water pressure resistance to be increased from 50 kPa of conventional ultrasonic welding to more than 70 kPa.

Detailed implementation manners

[0043] The following further elaborates on the present application in conjunction with all the attached drawings. Embodiment

[0044] Refer to Figure 1 , a braking system box, including a box body 1 and a breathable and waterproof structure 2 provided on the box body 1, wherein the box body 1 includes a bottom plate 11 and side plates 12, the box body 1 includes a bottom plate 11 and side plates 12 formed on both sides of the bottom plate 11, and an air outlet hole 111 is formed on one side of the bottom plate 11;

[0045] The breathable and waterproof structure 2 is located on one surface of the bottom plate 11, and uses this surface of the bottom plate 11 as the base material. The breathable and waterproof structure 2 includes breathable holes 21 provided on the bottom plate 11 (base material), a retaining ring 22 around the breathable holes 21 on the bottom plate 11, and a waterproof and breathable membrane 23 located inside the retaining ring 22 and fixed to the base material by ultrasonic welding;

[0046] The breathable holes 21 of the breathable and waterproof structure 2 are communicated with the air outlet holes 111; the shape of the breathable holes 21 is not limited to circular, and in other embodiments, it can also be square or other applicable shapes.

[0047] Refer to Figure 2 and Figure 3 , a convex edge 24 is formed at the position between the retaining ring 22 and the breathable holes 21 on the surface of the bottom plate 11. The convex edge 24 can also be semi-circular, semi-elliptical, triangular, or other structures with a gradually narrowing width of the cross-section in the direction away from the bottom plate 11.

[0048] The implementation principle of the embodiment of the present application is:

[0049] Since the waterproof and breathable film 23 of the breathable and waterproof structure 2 is ultrasonically welded to the bottom plate 11, its water pressure resistance is inherently stronger than that of adhesive connection. Secondly, in this solution, a convex edge 24 is provided between the retaining ring 22 and the ventilation holes 21. During ultrasonic welding, since the internal energy is used to melt the base material and combine it with the waterproof and breathable film 23, the convex edge 24 causes the heat to concentrate at the position of the convex edge 24 during ultrasonic welding, and when the melted material combines with the waterproof and breathable film 23, a connection structure with a more tightly connected circle can be formed, enabling the water pressure resistance to be increased from 50 kPa of conventional ultrasonic welding to more than 70 kPa;

[0050] Since the air outlet 111 is located on the side surface of the bottom plate 11, when the vehicle wades through water and the water flow impacts and enters the air outlet 111, it will not directly act on the waterproof and breathable film 23. Instead, it will first consume kinetic energy on the bottom surface of the air outlet 111 and then contact the waterproof and breathable film 23, which can effectively prevent the large water flow impact from causing greater water pressure to damage the waterproof and breathable film 23. Embodiment

[0051] Refer to Figure 4 and Figure 5 A kind of ultrasonic welding equipment for producing a brake system box, including a base 3, a rotating disk 31 arranged on the base 3, and a driving member 32 for driving the rotating disk 31 to rotate; four limiting grooves 311 for placing the brake system box are arranged on the rotating disk 31, the driving member 32 is a driving motor 321 fixedly arranged inside the base 3, and the upper end of the driving motor 321 penetrates through the upper side surface of the base 3 and is fixedly connected to the middle part of the rotating disk 31;

[0052] A support cross beam 33 is fixedly arranged on the base 3, and a welding assembly 4 is arranged on the support cross beam 33. The welding assembly 4 includes an ultrasonic welding head 41 rotatably arranged on the bottom side of the support cross beam 33 and above the rotating disk 31, and a power member 42 fixedly arranged on the upper side surface of the support cross beam 33. Among them, the welding head 41 is a conventional welding structure, and the power member 42 is a cylinder fixedly arranged at the upper end of the support cross beam 33 for driving the welding head 41 to move up and down, which will not be elaborated here.

[0053] Refer to Figure 4 Four universal wheels 34 with foot brakes are fixedly arranged on the bottom side surface of the base 3, and traction handles 35 are arranged on the opposite side surfaces of the base 3. The ultrasonic welding equipment can be pulled through the traction handles 35, and it can slide on the ground through the universal wheels 34 to realize the short-distance movement of the equipment. After the position is adjusted, the universal wheels 34 are locked.

[0054] Refer to Figure 5, a support rod 5 is slidably arranged vertically on the side of the base 3 close to the traction handle 35. An adjusting rod 51 is fixedly arranged on the outer periphery of the support rod 5 away from the base 3. A guiding inclined surface 511 is arranged on the edge of the end of the adjusting rod 51 away from the support rod 5. An elastic pad 52 made of rubber is fixedly arranged on the lower end of the support rod 5;

[0055] The lower end of the traction handle 35 is rotatably connected to the side of the base 3, and a positioning rod 351 that can rotate above the adjusting rod 51 along the guiding inclined surface 511 is fixedly arranged on the traction handle 35; when the lower side of the positioning rod 351 abuts against the upper side of the adjusting rod 51, the lower end of the support rod 5 abuts against the ground, thereby improving the installation stability of the base 3 in this state.

[0056] Refer to Figure 5 , a limiting plate 53 is fixedly arranged on the outer peripheral surface of the support rod 5, and a receiving plate 36 located directly below the limiting plate 53 is fixedly arranged on the side of the base 3. A spring 6 in a compressed state is fixedly arranged on the upper side of the receiving plate 36, and the other end of the spring 6 is fixedly connected to the bottom side of the limiting plate 53;

[0057] Under normal conditions, the spring 6 exerts pressure on the limiting plate 53 to keep the support rod 5 under a force that moves vertically upward. There is a gap between the bottom side of the support rod 5 and the ground in this state and it does not abut against the ground; when the positioning rod 351 on the traction handle 35 rotates above the adjusting rod 51, the compression spring 721 is compressed, and the entire support rod 5 moves vertically downward, and the lower end of the support rod 5 abuts against the ground.

[0058] Refer to Figure 6 , a protective cover 7 made of a flexible material is fixedly arranged on the side of the support cross beam 33 facing the base 3. A fixing ring 71 is fixedly arranged on the outer periphery of the lower edge of the protective cover 7; when the device is in use, the protective cover 7 can be folded and stored under the support cross beam 33;

[0059] When the device is not in use, the protective cover 7 can be unfolded towards the direction close to the base 3 and sleeved on the outer periphery of the rotating disc 31, thereby protecting the welding head 41 and the rotating disc 31 and reducing the possibility of external dust or other impurities adhering to the welding head 41 and the rotating disc 31.

[0060] Refer to Figure 7 and Figure 8, a receiving annular groove 331 for folding and placing the protective cover 7 is formed on the side of the supporting cross beam 33 facing the substrate. An elastic clamping member 72 is arranged on the outer periphery of the fixing ring 71. The elastic clamping member 72 includes a compression spring 721 and an arc-shaped convex block 722. A placing groove 711 for placing the compression spring 721 and the arc-shaped convex block 722 is formed on the outer periphery of the fixing ring 71. The compression spring 721 presses the arc-shaped convex block 722 so that a part of the arc-shaped convex block 722 protrudes from the opening of the placing groove 711. The protruding part of the arc-shaped convex block 722 is an arc surface, and the corresponding arc length of the arc surface is a minor arc. A first positioning groove 332 for inserting the elastic clamping member 72 is formed on the inner wall of the receiving annular groove 331;

[0061] When adjusting the protective cover 7 to the receiving state, the staff needs to fold the protective cover 7 upward, place the fixing ring 71 inside the receiving annular groove 331, and at the same time, make the protruding part of the arc-shaped convex block 722 snap into the first positioning groove 332, so as to realize the folding and receiving of the protective cover 7.

[0062] Refer to Figure 9 , a locking snap ring 37 sleeved outside the rotating disk 31 is fixedly arranged on the base 3, and there is a gap between the inner wall of the locking snap ring 37 and the outer periphery of the rotating disk 31. A second positioning groove 371 for inserting the elastic clamping member 72 is formed on the outer periphery of the locking snap ring 37;

[0063] When the protective cover 7 is unfolded downward, the fixing ring 71 can be sleeved on the outer periphery of the locking snap ring 37, and at the same time, the elastic clamping member 72 on the fixing ring 71 is inserted into the corresponding second positioning groove 371, so as to realize the fixation of the lower edge of the protective cover 7 and the upper side of the base 3.

[0064] Refer to Figure 9 , a locking member 8 capable of locking the fixing ring 71 is arranged on the base 3; when the support rod 5 slides upward, the locking member 8 can drive the locking of the fixing ring 71 abutted against the upper side of the base 3; when the support rod 5 slides downward, the locking member 8 can unlock the fixing ring 71 in the locked state. The locking member 8 includes a hinge seat 81 fixedly arranged on the upper side of the base 3 and a locking rod 82 hinged to the hinge seat 81 in the middle. A locking convex block 821 is fixedly arranged on the outer periphery of one end of the locking rod 82. The fixing ring 71 can be placed in the gap between the locking convex block 821 and the base 3; an extension rod 54 extending above the base 3 is fixedly arranged at the upper end of the support rod 5, and the upper end of the extension rod 54 abuts against the bottom side of the end of the locking rod 82 away from the locking convex block 821;

[0065] A torsion spring (not shown in the figure) is provided inside the hinge seat 81. This torsion spring is used to keep the locking rod 82 under a force that rotates it towards the extension rod 54, so that the upper end of the extension rod 54 abuts tightly against the bottom side of the locking rod 82. When the extension rod 54 slides upward, it drives the locking rod 82 to rotate around the hinge axis on the hinge seat 81, and the torsion spring is tightened. When the extension rod 54 slides downward, the extrusion on the bottom side of the locking rod 82 stops, the torsion spring resets and drives the locking rod 82 to rotate, so that the bottom side of the locking rod 82 remains in a tightly abutting state with the upper end of the extension rod 54.

[0066] When the extension rod 54 slides upward, the locking lug 821 rotates towards the base 3, and can tightly abut the upper side of the fixing ring 71 that abuts against the upper side of the base 3. When the extension rod 54 slides downward, under the action of the torsion spring, the locking lug 821 rotates away from the base 3, releasing the tight locking of the fixing ring 71 that abuts against the upper side of the base 3. In addition, due to the arrangement of the extension rod 54, the locking rod 82 and the hinge seat 81, the up-and-down sliding stroke of the support rod 5 can also be limited and adjusted, avoiding damage to components caused by excessive upward or downward sliding of the support rod 5.

[0067] The implementation principle of the embodiment of this application is as follows:

[0068] When the device is not in use, the protective cover 7 can be unfolded towards the base 3 and sleeved on the outer periphery of the rotating disk 31. At the same time, the elastic clamping member 72 on the fixing ring 71 is inserted into the corresponding second positioning groove 371. Then, the traction handle 35 is rotated downward, so that the spring 6 squeezes the support rod 5 to drive it to slide upward, and the extension rod 54 slides upward synchronously. And the locking lug 821 rotates around the hinge axis on the hinge seat 81 towards the base 3, and can tightly lock the fixing ring 71 that abuts against the upper side of the base 3. In this way, the welding head 41 and the rotating disk 31 are protected, reducing the possibility of external dust or other impurities adhering to the welding head 41 and the rotating disk 31.

[0069] When the device is in normal use, first rotate the traction handle 35 upward, so that the positioning rod 351 on the traction handle 35 rotates above the adjusting rod 51. At the same time, the compression spring 721 is squeezed, and the whole support rod 5 moves downward along the vertical direction, and the lower end of the support rod 5 abuts against the ground. The torsion spring drives the locking lug 821 to rotate around the hinge axis on the hinge seat 81 away from the base 3, thereby unlocking the fixing ring 71 that abuts against the upper side of the base 3.
