Description

Technical Field

[0001] This utility model belongs to the field of motor vehicle parts technology, and more specifically, it relates to the welded bracket in the pipeline of an automotive thermal management system. Background Technology

[0002] The thermal management system pipe support for new energy vehicles is a key component that ensures a stable connection between the pipes and the vehicle and guarantees the reliable operation of the vehicle's thermal management system. It is primarily used to fix and support the management system pipes. Currently, aluminum, steel, or stainless steel pipes and supports are typically fixed together by welding. This involves pre-placing the pipes, welding supports, and welding rods on the fixture of an automatic welding machine before automatic welding. However, traditional welding supports have outward-sloping or flat edges, making it difficult to place the welding rods there. Furthermore, during welding, the welding rods are prone to displacement along the outward-sloping surface of the support, leading to issues such as incomplete welds, missed welds, and weld melt leakage at the contact points between the pipes and the welding support edges, severely reducing welding quality. In addition, the structure of traditional welding supports is relatively fixed, making it impossible to flexibly adjust according to the spacing requirements of the two sets of pipes, thus reducing the spatial applicability of pipe installation. Utility Model Content

[0003] The welding bracket in the automotive thermal management system provided by this utility model solves the problems of traditional welding brackets having an outwardly inclined or planar welding position at the edge, which causes the welding rod to shift along the outwardly inclined surface, reducing the welding quality, and the welding bracket being unable to be flexibly adjusted according to the spacing requirements of the two sets of pipelines.

[0004] This utility model provides a welding bracket for automotive thermal management system piping, including a bracket assembly; the bracket assembly includes a welding frame, a telescopic plate, a knob, a slide, a push-pull column, a bidirectional threaded rotating rod, a fixed frame, and gaskets; the outer side of the bidirectional threaded rotating rod is rotatably connected to the fixed frame, and gaskets are adhered to both the upper and lower sides of the fixed frame; the inner side of the fixed frame is slidably connected to the telescopic plate, and the telescopic plate is welded to the welding frame; a pipe is placed on the upper side of the welding frame, and welding rods are placed on the edge of the welding frame; a knob is welded to both the front and rear ends of the bidirectional threaded rotating rod; a push-pull column is welded to the upper side of the slide.

[0005] Furthermore, the fixing frame is a rectangular cylindrical structure that runs through the left and right sides. The telescopic plate is embedded in the inner side of the rectangular cylindrical structure of the fixing frame. The front and rear sides of the telescopic plate are attached to the front and rear cylindrical walls of the rectangular cylindrical body of the fixing frame. The upper and lower sides of the rectangular cylindrical structure of the fixing frame are provided with through holes at their center positions. The upper side of the fixing frame is provided with long through grooves near the left and right ends.

[0006] Furthermore, the number of carriages is two sets, symmetrically distributed front and back. Each set of carriages is an inverted T-shaped structure. The front side of the T-shaped structure of the carriage is provided with a threaded through hole that runs through the front and back. The forward threaded end of the outer side of the bidirectional threaded rotating rod is engaged and connected to the threaded through hole of the front carriage, and the reverse threaded end of the outer side of the bidirectional threaded rotating rod is engaged and connected to the threaded through hole of the rear carriage. Two sets of push-pull columns are welded to the upper side of the carriage. Each set of push-pull columns is a cylindrical structure, and the top of the push-pull column is embedded in the long through groove of the fixed frame.

[0007] Furthermore, the telescopic plates are in two sets, and each set of telescopic plates has two sets of symmetrical oblique through grooves on its upper side, with push-pull columns inserted into the oblique through grooves of the telescopic plates.

[0008] Furthermore, the welding frame consists of two sets, each set being a semi-circular arc plate structure. The top part of the semi-circular arc plate structure of the welding frame is an inwardly inclined 45-degree slope structure, and welding rods are placed on the upper side of the slope structure of the welding frame.

[0009] Furthermore, the number of gaskets is two sets, and each set of gaskets has a through hole at the center. The through holes of the gaskets are vertically aligned with the through holes of the fixing frame, and the entire gasket is made of rubber.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The utility model utilizes a 45-degree inward tilted slope structure at the top of the welding frame, which allows the welding rod to be stably attached to the contact area between the pipe and the welding frame under gravity. This avoids the welding rod shifting caused by the outward tilt or flat structure of traditional supports, prevents incomplete welding, missed welding and welding liquid leakage, and improves the welding reliability of the pipeline and the support.

[0011] 2. The utility model utilizes a threaded transmission mechanism formed by a bidirectional threaded rotating rod within two sets of threaded through holes in the slide, which causes the push-pull column to push two sets of telescopic plates to move in opposite directions to the left and right within the fixed frame via an oblique through groove. This allows the spacing between the welding frames to be flexibly adjusted according to the actual pipeline layout requirements, thereby improving the versatility and applicability of the thermal management system pipeline spatial layout in different vehicle models.

[0013] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0014] like Figures 1-7 As shown, this utility model provides a welding bracket in the pipeline of an automotive thermal management system, including a bracket device 3; the bracket device 3 includes a welding frame 301, a telescopic plate 302, a knob 303, a slide 304, a push-pull column 305, a bidirectional threaded rotating rod 306, a fixed frame 307, and a gasket 308; the outer side of the bidirectional threaded rotating rod 306 is rotatably connected to the fixed frame 307, and the upper and lower sides of the fixed frame 307 are both bonded with gaskets 308; the inner side of the fixed frame 307 is slidably connected to the telescopic plate 302, and the telescopic plate 302 is welded to the welding frame 301; a pipe fitting 1 is placed on the upper side of the welding frame 301, and a welding rod 2 is placed on the edge of the welding frame 301; the front end and rear end of the bidirectional threaded rotating rod 306 are both welded with knobs 303; the upper side of the slide 304 is welded with a push-pull column 305.

[0015] In this embodiment of the utility model, the fixing frame 307 is a rectangular cylindrical structure that runs through the left and right sides. The telescopic plate 302 is embedded in the inner side of the rectangular cylindrical structure of the fixing frame 307. The front and rear sides of the telescopic plate 302 are attached to the front and rear cylindrical walls of the rectangular cylindrical body of the fixing frame 307. The front and rear cylindrical walls of the fixing frame 307 provide left and right limiting support for the telescopic plate 302, allowing the telescopic plate 302 to move left and right along the rectangular cylindrical structure of the fixing frame 307, preventing the telescopic plate 302 from shifting left and right, and ensuring that the two sets of telescopic plates 302 drive the two sets of welding frames 301 to stably extend and retract to adjust the spacing. The upper and lower sides of the rectangular cylindrical structure of the fixing frame 307 are provided with through holes at their center positions, and the upper side of the fixing frame 307 is provided with long through grooves near the left and right ends.

[0016] In this embodiment of the invention, there are two sets of slides 304, symmetrically distributed front and rear. Each set of slides 304 is an inverted T-shaped structure. The front side of the T-shaped structure of each slide 304 is provided with a threaded through hole running through the front and rear. The forward threaded end of the outer side of the bidirectional threaded rotating rod 306 is engaged with the threaded through hole of the front slide 304, and the reverse threaded end of the outer side of the bidirectional threaded rotating rod 306 is engaged with the threaded through hole of the rear slide 304. The upper side of the slide 304 is welded with... There are two sets of push-pull columns 305, each of which is a cylindrical structure. The top of the push-pull column 305 is embedded in the long through groove of the fixed frame 307. When the knob 303 drives the bidirectional threaded rod 306 to rotate, the bidirectional threaded rod 306 drives the two sets of slides 304 connected on the outer side to move back and forth in opposite directions under the nested support of the long through groove of the fixed frame 307 and the push-pull column 305, so as to ensure that the two sets of push-pull columns 305 push the groove wall structure of the inclined through groove of the telescopic plate 302 in a directional manner.

[0017] In this embodiment of the utility model, there are two sets of telescopic plates 302. Each set of telescopic plates 302 has two sets of symmetrical oblique through slots on its upper side. Push-pull columns 305 are inserted into the oblique through slots of the telescopic plates 302. When the two sets of slides 304 move in opposite directions, the push-pull columns 305 welded to the upper side of the slides 304 push the groove wall of the oblique through slot of the telescopic plate 302, so that the push-pull columns 305 push the two sets of telescopic plates 302 to move in opposite directions in opposite directions in the inner side of the fixed frame 307 along the oblique through slot. This allows the two sets of telescopic plates 302 to drive the two sets of welding frames 301 to adjust the spacing, thereby flexibly changing the arrangement and placement spacing of the two sets of pipe fittings 1.

[0018] In this embodiment of the utility model, there are two sets of welding frames 301. Each set of welding frames 301 is a semi-circular arc plate structure. The top part of the semi-circular arc plate structure of the welding frame 301 is an inwardly inclined slope structure at 45 degrees. Welding rods 2 are placed on the upper side of the inclined slope structure of the welding frame 301. When welding the welding frame 301 to the outer wall of the pipe 1, it is ensured that the welding rods 2 adhere to the outer wall of the pipe 1 along the inwardly inclined slope structure of the welding frame 301 by gravity, so as to avoid the welding rods 2 shifting to the outside, causing the welding frame 301 to have a poor weld, missing weld, or weld liquid leakage at the joint between the welding frame 301 and the outer wall of the pipe 1.

[0019] In this embodiment of the utility model, there are two sets of gaskets 308. Each set of gaskets 308 has a through hole at its center. The through holes of the gaskets 308 are vertically opposite to the through holes of the fixing bracket 307. The gaskets 308 are made of rubber. Bolts are inserted into the through holes of the gaskets 308 and the fixing bracket 307, so that the gaskets 308 bonded to the fixing bracket 307 are attached to the mounting holes of the vehicle body by bolts and nuts. The rubber gaskets 308 have good elasticity and deformation capacity, which can effectively absorb the vibration and impact during vehicle operation, reduce the noise and wear of the pipeline system caused by vibration, and protect the stability of the pipeline connection.

[0020] In this invention, when adjusting the spacing between the two sets of welding frames 301 and the two sets of pipe fittings 1, a flathead screwdriver drives a knob 303 to rotate, which in turn drives a bidirectional threaded rod 306 to rotate synchronously. Since the forward and reverse threaded ends of the outer side of the bidirectional threaded rod 306 are respectively engaged in the threaded through holes of the two sets of slides 304, the bidirectional threaded rod 306 drives the two sets of slides 304 to move back and forth along the elongated through groove of the fixed frame 307. The two sets of push-pull columns 305 welded to the upper side of each set of slides 304 push against the oblique through groove wall structure of the telescopic plate 302, causing the telescopic plate 302 to move left and right along the inner side of the rectangular cylindrical structure of the fixed frame 307, thereby completing the adjustment of the spacing between the two sets of welding frames 301 and the two sets of pipe fittings 1. During the welding process of placing welding rod 2 between welding frame 301 and pipe fitting 1, welding rod 2 is first placed on the 45-degree inward-sloping surface at the top of the semi-circular arc plate structure of welding frame 301. Then, the automatic welding machine melts welding rod 2 at high temperature. The molten welding rod 2 accumulates in the groove formed between the sloped surface of welding frame 301 and pipe fitting 1 for solidification welding. This avoids the welding rod 2 shifting outward, which could cause incomplete welding, missing welds, and weld melt leakage at the welding points where the edge of welding frame 301 touches the outer wall of pipe fitting 1.

[0021] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The pipe fittings 1 and welding rods 2 mentioned above are common commercially available components; upon purchase and use, simply follow the instruction manual provided with the purchase, and therefore will not be elaborated upon further.

[0022] The technical solution of this utility model is not limited to the scope of the embodiments of this utility model. All technical contents not described in detail in this utility model are known technologies.
