Description

Technical Field

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

[0002] In modern automobile manufacturing, the integrated brake-by-wire system box is a key component and is usually placed on the chassis of the car. The choice of this location takes into account both the functional requirements of the system and the overall layout and space design of the vehicle. However, the integrated brake-by-wire system box generates a lot of heat during operation, which poses a potential threat to the stability and life of the system.

[0003] In order to achieve the dual goals of heat dissipation and waterproofing, engineers cleverly set a waterproof breathable membrane on the vent hole of the brake system box. This membrane material not only has good air permeability, which can ensure effective heat dissipation of the system box during normal operation, but also its waterproof properties can effectively prevent external moisture from entering the system, thereby avoiding system failure or damage caused by wading and other reasons. In the current automotive manufacturing field, the traditional process of gluing is mostly used for the installation of waterproof breathable membranes. Specifically, a specific adhesive is used to firmly bond the waterproof breathable membrane to the position of the vent hole.

[0004] However, the gluing method has also exposed some problems in practical applications. The most prominent of which is its limited ability to withstand water pressure. According to tests, the waterproof breathable membrane installed by gluing can usually only withstand water pressure of about 25kpa. This means that when facing a large water pressure, the membrane material may break or fall off due to the inability to withstand 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 wire control brake system, but may also pose a potential threat to driving safety, and there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a brake system box and ultrasonic welding equipment for producing brake system boxes, so as to solve the problem in the above-mentioned related technology that the waterproof and breathable membrane has poor ability to withstand water pressure, thus affecting the waterproof performance of the system box.

[0007] By adopting the above technical solution, the waterproof breathable membrane and the bottom plate are ultrasonically welded to improve the water pressure resistance. Secondly, a convex edge is set within the coverage of the welding area. The setting of the convex edge allows the heat to be concentrated at the convex edge during ultrasonic welding, and the melted material can form a more tightly connected connection structure when combined with the waterproof breathable membrane, so that the water pressure resistance can be increased from 50kpa of conventional ultrasonic welding to more than 70kpa.

[0008] In the second aspect, the ultrasonic welding equipment for producing a brake system box provided by the present application adopts the following technical solution: An ultrasonic welding device for producing brake system boxes includes a base, a rotating disk arranged on the base, and a driving member that drives the rotating disk to rotate; the rotating disk is provided with a limit groove for the brake system box to be placed, the base is fixed with a supporting beam, the supporting beam is provided with a welding head located above the limit groove on the rotating disk, and a power member that drives the welding head to move up and down.

[0013] Optionally, an elastic pad is fixedly provided on the lower end of the support rod.

[0014] By adopting the above technical solution, when the support rod moves downward, the elastic pad on the support rod is brought into contact with the ground, thereby increasing the possibility of wear when the support rod contacts the ground and extending the service life of the support rod.

[0021] Optionally, a receiving ring groove for the protective cover to be folded and placed is provided on the side of the supporting beam facing the base plate, an elastic clip is provided on the outer periphery of the fixing ring, and a first positioning groove for the elastic clip to be inserted is provided on the inner wall of the receiving ring groove.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] Embodiment 1: Reference Figure 1 A brake system box includes a box body 1 and a breathable and waterproof structure 2 arranged on the box body 1, wherein the box body 1 includes a bottom plate 11 and a side plate 12, and the box body 1 includes the bottom plate 11 and the side plates 12 formed on both sides of the bottom plate 11, wherein one side of the bottom plate 11 is formed with an air outlet 111; The breathable waterproof structure 2 is located on one side of the bottom plate 11, and the side of the bottom plate 11 is used as a substrate. The breathable waterproof structure 2 includes a breathable hole 21 arranged on the bottom plate 11 (substrate), a retaining ring 22 on the bottom plate 11 surrounding the breathable hole 21, and a waterproof breathable membrane 23 located in the retaining ring 22 and fixed to the substrate by ultrasonic welding; The air holes 21 of the breathable waterproof structure 2 are connected to the air outlet holes 111 ; the shape of the air holes 21 is not limited to a circle, and in other embodiments, it can also be a square or other applicable shape.

[0031] Reference Figure 2 and Figure 3 A circle of protrusion 24 is formed on the surface of the bottom plate 11 between the retaining ring 22 and the air vent 21 . The protrusion 24 can also be a semicircular, semi-elliptical, triangular or other cross-sectional structure whose width gradually narrows away from the bottom plate 11 .

[0032] The implementation principle of the embodiment of the present application is: Since the waterproof breathable membrane 23 of the breathable waterproof structure 2 is ultrasonically welded to the bottom plate 11, the water pressure resistance is inherently stronger than that of adhesive connection. Secondly, in this solution, a circle of convex edges 24 is set between the retaining ring 22 and the vent hole 21. During ultrasonic welding, the base material is melted and combined with the waterproof breathable membrane 23 by internal energy. The setting of the convex edge 24 allows heat to be concentrated at the position of the convex edge 24 during ultrasonic welding, and the melted material can form a circle of more tightly connected connection structure when combined with the waterproof breathable membrane 23, so that the water pressure resistance can be increased from 50kpa of conventional ultrasonic welding to more than 70kpa; Since the air outlet 111 is located on the side of the bottom plate 11, when the car is wading and the water flow impacts the air outlet 111, it will not directly act on the waterproof breathable membrane 23, but will first consume kinetic energy on the bottom surface of the air outlet 111 before contacting the waterproof breathable membrane 23, which can effectively prevent the waterproof breathable membrane 23 from being damaged by a large water pressure caused by a large water flow impact.
