Description

Technical Field

[0001] This utility model relates to the technical field of automotive engine components, and more specifically, to a stable bracket for the exhaust pipe of an EGR cooler. Background Technology

[0002] EGR stands for Exhaust Gas Recirculation, a technology that returns a small portion of the exhaust gas produced by the engine to the cylinder for re-combustion. Specifically, it mixes the exhaust gas from the engine with fresh air before it enters the cylinder, with the main purpose of reducing nitrogen oxide (NOx) emissions in the exhaust. Currently, EGR pipes are typically designed with separate coolant pipes and exhaust pipes, as two separate components, which are then fixed to the cylinder head. This results in high space requirements and a non-compact structure.

[0003] Existing EGR cooler exhaust pipes are surrounded by numerous engine and EGR valve wiring harnesses during operation. However, when the vehicle is running, engine vibrations and increased engine compartment temperatures can cause common wiring harness straps to age and break over time. This can lead to wiring harness movement due to vibrations during driving, increasing the risk of wear and short circuits, and ultimately affecting driving safety. Therefore, an EGR cooler exhaust pipe stabilizing bracket has been introduced to address these issues. Utility Model Content

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides an EGR cooler exhaust pipe stabilizing bracket. The technical problem to be solved by the present invention is that when a vehicle is started and driven, the engine vibrates and the temperature inside the engine compartment rises. Some common wiring harness straps will also age and break due to prolonged use. The wiring harness may move due to vibration during vehicle operation, increasing the risk of wiring harness wear and short circuit, thereby affecting driving safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an EGR cooler outlet pipe stabilizing bracket, including a pipe assembly, wherein multiple binding components are sleeved on the surface of the pipe assembly, and multiple limiting components are provided on the surface of the pipe assembly.

[0006] The binding assembly includes a first half-ring, one end of which is fixedly connected to a first rotating block. The first rotating block is rotatably connected to a second rotating block. One end of the second rotating block is fixedly connected to a second half-ring. A functional block is fixedly connected to the bottom of the second half-ring. The top of the inner cavity of the functional block has multiple movable slots, and the bottom of the functional block has multiple fixed slots. A spring is fixedly connected to the top of each movable slot, and the other end of each spring is fixedly connected to a beveled block. A metal strip is provided at the bottom of the functional block, and multiple fixing holes are provided on the surface of the metal strip. Multiple locking bolts are provided on one end of the surface of the metal strip.

[0007] In a preferred embodiment, the limiting component includes a connecting plate, on both sides of which inclined vertical plates are fixedly connected, and on the top of the connecting plate are multiple locking posts. A main enclosure frame is provided at the bottom of the connecting plate, and on both sides of the main enclosure frame are multiple threaded posts. Multiple threaded grooves are provided on the outer surface of each inclined vertical plate, and a side enclosure frame is provided on the outer surface of each inclined vertical plate.

[0008] In a preferred embodiment, the air tube assembly includes an air outlet bend, one end of which is fixedly connected to a first fixing plate, and the other end of which is fixedly connected to a second fixing plate. A plurality of connecting posts are fixedly connected to the surface of the air outlet bend, and each connecting post has a threaded opening on its surface.

[0009] In a preferred embodiment, the ends of the first and second half-rings away from the first and second rotating blocks are fixedly connected by bolts, and due to the presence of the inclined block, the metal strip can only be pulled in one direction.

[0010] In a preferred embodiment, the main enclosure frame and the connecting plate are connected by a threaded post penetrating the connecting plate and a locking post, and the side enclosure frame and the inclined vertical plate are also connected by a threaded post and a threaded groove.

[0011] In a preferred embodiment, each of the inclined vertical plates has a connection port on its surface, and the inner diameter of the connection port is the same as the diameter of the connecting column.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by providing an air tube assembly and a limiting assembly, allows for direct connection between the connecting post and the connection ports on the surfaces of the two inclined vertical plates during later use. The connection is then secured with bolts larger than the diameter of the connecting post, ensuring that the limiting assembly will not rotate around the air outlet bend during later use, thus improving stability. Furthermore, thicker wire harnesses can be placed inside the main enclosure frame, while thinner wire harnesses can be placed inside the side enclosure frames on the outer side of the inclined vertical plates, making wire harness sorting more convenient during later use.

[0014] 2. This utility model, by providing a binding component, allows for direct connection of the first and second half-rings to the surface of the exhaust bend during later use. After the first and second half-rings are fixedly connected, a new metal strip is taken out and fixed to the fixing groove with bolts. After the connection is completed, the metal strip is wrapped around all the wiring harnesses and then penetrated through the functional block. The fixing opening on the surface of the metal strip intersects with the vertical plane of the inclined block, allowing the metal strip to be pulled in only one direction. This avoids engine vibration and increased engine compartment temperature during vehicle startup and driving. Common wiring harness binding straps may also age and break due to prolonged use, causing the wiring harness to move due to vibration during vehicle operation, increasing the risk of wiring harness wear and short circuits, and thus affecting driving safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a stable support for the exhaust pipe of an EGR cooler, including an exhaust pipe assembly 1, a plurality of binding components 2 sleeved on the surface of the exhaust pipe assembly 1, and a plurality of limiting components 3 provided on the surface of the exhaust pipe assembly 1.

[0023] The binding assembly 2 includes a first half-ring 21, one end of which is fixedly connected to a first rotating block 22. The first rotating block 22 is rotatably connected to a second rotating block 24. One end of the second rotating block 24 is fixedly connected to a second half-ring 23. The bottom of the second half-ring 23 is fixedly connected to a functional block 25. The top of the inner cavity of the functional block 25 is provided with multiple movable grooves 26, and the bottom of the functional block 25 is provided with multiple fixed grooves 27. The top of each movable groove 26 is fixedly connected to a spring 28, and the other end of each spring 28 is fixedly connected to a slope block 29. The bottom of the functional block 25 is provided with a metal strip 210, the surface of the metal strip 210 is provided with multiple fixing holes 211, and one end of the surface of the metal strip 210 is provided with multiple locking bolts 212.

[0024] The limiting component 3 includes a connecting plate 31, with inclined vertical plates 32 fixedly connected to both sides of the connecting plate 31, multiple locking posts 33 fixedly connected to the top of the connecting plate 31, a main enclosure frame 34 provided at the bottom of the connecting plate 31, multiple threaded posts 35 provided on both sides of the main enclosure frame 34, multiple threaded grooves 36 provided on the outer surface of the inclined vertical plates 32, and side enclosure frames 37 provided on the outer surface of the inclined vertical plates 32.

[0025] The air pipe assembly 1 includes an air outlet bend 11, one end of which is fixedly connected to a first fixing plate 12, and the other end of which is fixedly connected to a second fixing plate 13. Multiple connecting posts 14 are fixedly connected to the surface of the air outlet bend 11, and each connecting post 14 has a threaded opening 15 on its surface.

[0026] Among them, the ends of the first half-ring 21 and the second half-ring 23 that are away from the first rotating block 22 and the second rotating block 24 are fixedly connected by bolts. Due to the presence of the inclined block 29, the metal strip 210 can only be pulled in one direction. The metal material of the metal strip 210 can withstand high temperature during use, avoiding the problem of ordinary straps breaking and causing the wire harness to scatter, which increases the risk of wire harness wear and short circuit.

[0027] The main enclosure frame 34 and the connecting plate 31 are connected by a threaded post 35 penetrating the connecting plate 31 and locking post 33. The side enclosure frame 37 and the inclined vertical plate 32 are also connected by a threaded post 35 and a screw groove 36. In use, a thicker wire harness can be placed inside the main enclosure frame 34, and a thinner wire harness can be placed inside the side enclosure frame 37 outside the inclined vertical plate 32, so as to make it easier to classify the wire harness in later use.

[0028] Each of the inclined vertical plates 32 has a connection port on its surface, and the inner diameter of the connection port is the same as the diameter of the connecting column 14. This ensures that the limiting component 3 will not rotate around the air outlet bend 11 during later use, thus ensuring stability.

[0029] Working principle of this utility model:

[0030] In use, the connection can be made directly through the connection port opened on the surface of the two inclined vertical plates 32 via the connecting column 14, and then fixed with bolts with a diameter larger than that of the connecting column 14. This ensures that the limiting component 3 will not rotate around the air outlet bend 11 during later use, thus improving stability. Secondly, a thicker wire harness can be placed in the main enclosure 34, and a thinner wire harness can be placed in the side enclosure 37 outside the inclined vertical plate 32, so that the wire harness can be sorted more conveniently during later use. Then, when using it, the first half-ring 21 and the second half-ring 23 can be directly intersected with the surface of the exhaust bend 11. After the first half-ring 21 and the second half-ring 23 are fixedly connected, a new metal strip 210 is taken out and fixed to the fixing groove 27 with bolts. After the connection is completed, the metal strip 210 is wrapped around all the wire harnesses and then the metal strip 210 is penetrated through the functional block 25. After the fixing port 211 on the surface of the metal strip 210 intersects with the vertical plane of the inclined block 29, the metal strip 210 can only be pulled in one direction. This avoids the engine shaking and the temperature rise in the engine compartment when the vehicle is started and driven. Some common wire harness straps will also be aged and damaged due to prolonged use. The wire harness may move due to vibration during vehicle driving, increasing the risk of wire harness wear and short circuit, which in turn affects driving safety.
