Description

Technical Field

[0001] The present invention relates to the technical field of heat shields, and particularly relates to a supercharger heat shield for a diesel engine and a manufacturing method thereof. Background Art

[0002] When the turbocharger on the engine is working, the high-temperature and high-pressure gas pushes the turbine to rotate, heating the turbine housing to a very high temperature. When it is necessary to repair the turbine, it is easy to scald the workers, which poses a certain danger. Moreover, a large amount of heat is dissipated from the surface of the high-temperature turbine housing to the surrounding, increasing the ambient temperature of the engine body. Using a heat shield to isolate the supercharger can solve the above problems. The existing isolation shields can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] Patent document CN206439105U discloses a supercharger heat shield, and its technical solution includes: a heat shield body for covering the outside of the supercharger, and a snap structure for fixing the heat shield body on the surface of the supercharger; the heat shield body includes an asbestos heat insulation layer, a support block, an aluminum foil surface layer, and a plurality of sequentially movably connected polyurethane foam boards, and the polyurethane foam boards are fixed on one side surface of the aluminum foil surface layer; the support block includes a vacuum plate and at least two springs, and the springs are respectively fixed on two opposite side surfaces of the vacuum plate. The springs on one side surface of the vacuum plate are connected to the polyurethane foam board, and the springs on the other side surface of the vacuum plate are connected to the asbestos heat insulation layer; a cavity is formed between the polyurethane foam board and the asbestos heat insulation layer, and the cavity is filled with air. This technical solution provides a supercharger heat shield with good heat insulation effect. When repairing the supercharger, using this heat shield can effectively solve the problem that workers are easily scalded when repairing the turbocharger.

[0004] As in the prior art of the above patent, when the heat shield is sleeved on the supercharger, the heat insulation and safety functions are achieved. However, due to the tight wrapping of the heat shield, the heat dissipation of the supercharger is extremely limited. Therefore, there is an urgent need for a supercharger heat shield for a diesel engine and a manufacturing method to solve the above problems. Summary of the Invention

The pulling members are provided with protruding portions facing the inner side of the skeleton. The support member is arranged between two adjacent protruding portions provided on the two pulling members respectively. A runner rotatably provided on the inner side of the shield body and synchronously rotating with the hook is provided, and the runner is in transmission connection with the pulling members.

[0012] Preferably, one end of the pulling member is provided with a convex tooth, and a tooth groove matching the convex tooth is provided on the runner.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0031] Please refer to Figures 1-6 , a supercharger heat shield for a diesel engine provided by an embodiment of the present invention includes a cover body 1 and hooks 2 provided at both ends thereof. After the cover body 1 is sleeved on the supercharger, the same tension spring 3 is tensioned between the two hooks 2. The hooks 2 are rotatably provided on the cover body 1, and further includes: a skeleton 4, which is detachably installed in the cover body 1; a support member 5, which is evenly provided with a plurality of inner sides of the skeleton 4 and is linked with the hooks 2. Before the cover body 1 is installed, the support member 5 has a first state in which it can swing and relax; and after the cover body 1 is installed, when the tension spring 3 tightens the two hooks 2, the support member 5 has a second state in which it radially supports on the outer surface of the supercharger and forms a heat dissipation gap between the cover body 1 and the supercharger.

[0032] Specifically, the cover body 1 is made of high temperature resistant fabric, such as silicone rubber fiberglass cloth; the cover body 1 includes two end faces and an outer baffle, and is approximately C-shaped as a whole, with an opening for easy installation on the supercharger; the center of the two end faces of the cover body 1 is left empty, and the interior is surrounded by a space that matches the shape and size of the applicable supercharger; the hook 2 is arranged on the outer side of the end face of the cover body 1, and a group of two hooks 2 are arranged on both end faces of the cover body 1; when the two hooks 2 are connected and tensioned with the same tension spring 3, they are close to each other and point to each other, and the preset position of the hook 2 deviates from the above close and relative position, thereby causing the hook 2 to rotate and change before and after the tension spring 3 is connected; hook rings are arranged at both ends of the tension spring 3, which can be hooked to the hook 2 for easy disassembly and assembly. The frame 4 is made of high temperature resistant material, has a certain bending elasticity, fits and matches the inner side of the outer baffle of the cover body 1, and can support the cover body 1; the frame 4 and the cover body 1 are detachable, that is, it is convenient for the cover body 1 to be separated for cleaning or other operations; the frame 4 is provided with a plurality of continuous through openings along the length direction. The support member 5 is also made of heat-resistant material and is hard. A notch is set at one end thereof for resisting the supercharger. Therefore, when the support member 5 props up the cover body 1 on the supercharger, the heat dissipation gap formed is completely connected to facilitate air flow. The propping height of the support member 5 is preferably 5-10mm. The support member 5 is perpendicular to the length direction of the frame 4, and corresponds to the solid part between every two openings set on the frame 4 and is movably connected. The first state of the support member 5 is that its bending and swinging close to the surface of the skeleton 4 is not restricted, thereby not directly causing space restriction in the cover body 1. During the installation of the cover body 1 on the supercharger, the support member 5 can be swung down to facilitate the cover body 1 to be mounted on the supercharger; the second state of the support member 5 is that its bending and swinging are restricted, and it remains upright on the skeleton 4, and when the cover body 1 is installed on the supercharger, the support member 5 is radially supported on the surface of the supercharger by the supercharger, and the support pin of this support member 5 separates a gap between the cover body 1 and the supercharger, which is the heat dissipation gap; the switching of the support member 5 from the first state to the second state corresponds to the two hooks 2 on the same end face of the cover body 1 being tightened by the same tension spring 3 to rotate, that is, when the cover body 1 is installed on the supercharger through the tension spring 3, the heat dissipation gap is formed synchronously. In actual use of the present technical solution, before the cover body 1 is installed, the support member 5 can be relaxed and swung in the first state, thereby not restricting the space inside the cover body 1 too much, and facilitating the installation of the cover body 1 on the supercharger. After the cover body 1 is installed, the two hooks 2 are rotated by the tension spring 3, and the linkage support member 5 is supported to reach the second state, so as to maintain radial support on the surface of the supercharger, so that a heat dissipation gap is formed between the cover body 1 and the supercharger, thereby promoting the heat dissipation of the supercharger and maintaining the heat insulation function unchanged.

[0033] Compared with the prior art, a supercharger heat shield of a diesel engine proposed in an embodiment of the present invention can support the housing 1 by arranging the skeleton 4. With the support member 5 provided, before the housing 1 is installed, the support member 5 can swing and relax in the first state, thus not overly restricting the space inside the housing 1 and facilitating the installation of the housing 1 on the supercharger. After the housing 1 is installed, the two hooks 2 rotate under the tension of the tension spring 3, which then drives the support member 5 to rise to reach the second state, so as to maintain radial support on the outer surface of the supercharger, form a heat dissipation gap between the housing 1 and the supercharger, promote the heat dissipation of the supercharger, and keep the heat insulation function unchanged, improving the practicability of the device.

[0034] Furthermore, when the housing 1 is correctly sleeved on the supercharger, a heat dissipation gap formed between it and the outer surface of the supercharger is open at one end and provided with a drainage fan 18 at the other end. The drainage fan 18 is fixedly arranged on the housing 1, with the air inlet facing one end of the heat dissipation gap. With the multi-pass opening of the skeleton 4 being hollowed out, the drainage fan 18 can drive the air in the heat dissipation gap. The drainage fan 18 can be controlled by the vehicle machine system to actively drive the air in the heat dissipation gap, achieving an active heat dissipation effect. In addition, the air outlet of the drainage fan 18 can be connected to the global temperature control system in the vehicle machine. On the one hand, it avoids the impact on nearby equipment caused by concentrated heat dissipation. On the other hand, it can transfer the heat to the required position in the vehicle machine, improving the performance of the vehicle machine system.

[0035] As a preferred technical solution of this embodiment, the support member 5 is connected to the skeleton 4 through a swinging part 6. The swinging part 6 has bending elasticity. Specifically, the setting of the swinging part 6 enables the support member 5 to swing, and the elasticity of the swinging part 6 enables the support member 5 to maintain a state of standing vertically on the surface of the skeleton 4 when not subject to external forces, facilitating the support member 5 to turn to the second state.

[0036] As a preferred technical solution of this embodiment, female buttons 7 are arranged on the outer sides of both ends of the skeleton 4, and male buttons 8 matching the female buttons 7 are arranged on the inner side of the housing 1. Specifically, the female buttons 7 and the male buttons 8 form a push-button structure, facilitating the installation or disassembly of the housing 1 on the skeleton 4.

[0037] As a preferred technical solution of this embodiment, a clamping assembly is provided on the skeleton 4, and the clamping assembly is linked with the rotation of the hook 2. When the hook 2 is rotated by the tension spring 3, the clamping assembly clamps the two opposite sides of the support member 5 so that the support member 5 remains supported on the skeleton 4. Specifically, the clamping assembly includes two force application points. When the two force application points approach the support member 5 from the opposite sides of the support member 5 in the length direction of the skeleton 4 and directly act on the support member 5, the support member 5 remains vertically upright on the surface of the skeleton 4; and when the two force application points move away from the opposite sides of the support member 5 in the length direction of the skeleton 4, the support member 5 is not restricted by external force and can swing freely by relying on the swinging part 6; the process of the clamping assembly driving the two force application points to move is linked with the rotation of the hook 2. When the two hooks 2 are rotated by the tension spring 3, the clamping assembly drives the two force application points to approach the support member 5 synchronously, so that the support member 5 can be clamped and remain supported on the skeleton 4.

[0038] As a further preferred technical solution of this embodiment, the clamping assembly includes two relatively movable drawer members 9 movably arranged on the sides of the frame 4, the drawer member 9 is provided with a protrusion 10 facing the inner side of the frame 4, the support member 5 is arranged on the two drawer members 9 and between two adjacent protrusions 10, and a rotating wheel 11 that rotates synchronously with the hook 2 is rotatably arranged on the inner side of the cover body 1, and the rotating wheel 11 is transmission-connected with the drawer member 9. Specifically, a plurality of guide sleeves are equidistantly arranged on the sides of the frame 4, and the drawer member 9 slides through each guide sleeve arrangement. The drawer member 9 is arranged in the same length extension direction as the frame 4, and a group of two drawers are arranged on both sides of the frame 4. The pull-out pieces 9 are arranged on the same side of the frame 4 and move relative to each other side by side; both ends of the support piece 5 extend to the range where the pull-out pieces 9 are located; in the two pull-out pieces 9 on the same side, a support piece 5 is arranged between the raised portion 10 on one of the pull-out pieces 9 and the raised portion 10 on the other pull-out piece 9; the rotating wheel 11 is arranged to fit the inner side of the end surface of the cover body 1, and the pull-out pieces 9 on the side of the frame 4 are also arranged to fit the inner side of the end surface of the cover body 1, so that they can be in the same or similar plane that can interact with the rotating wheel 11 on the same side; the rotation of the rotating wheel 11 causes the pull-out pieces 9 to slide along the direction in which their lengths are extended. In actual use of the present technical solution, after the cover body 1 is correctly sleeved on the supercharger, the two hooks 2 are connected by the tension spring 3. Then, under the tension of the tension spring 3, the two hooks 2 approach each other and point to each other, and the hook 2 rotates, driving the rotating wheel 11 to rotate synchronously, and the rotating wheel 11 links the drawer 9 to slide, and the two drawers 9 on the same side move relatively to make the two protrusions 10 corresponding to the same support member 5 approach each other, thereby clamping the support member 5, so that the support member 5 remains supported on the frame 4, that is, radially supported on the surface of the supercharger so that the heat dissipation gap between the cover body 1 and the supercharger is stably formed.

[0039] As a further preferred technical solution of this embodiment, a convex tooth 12 is provided at one end of the drawer member 9, and a tooth groove 13 matching the convex tooth 12 is provided on the runner 11. Specifically, the convex tooth 12 is provided on the side of the drawer member 9 close to the runner 11, which can be approximately in the shape of a rack, and a plurality of tooth grooves 13 are uniformly arranged on the outer circumference of the runner 11, which can be approximately in the shape of a gear. The drawer member 9 and the runner 11 achieve a meshing transmission relationship through the meshing of the convex tooth 12 and the tooth groove 13. Then, when the runner 11 rotates synchronously with the hook 2, the drawer member 9 is driven to slide. Further, when the rotation direction of the hook 2 points to another hook 2, the corresponding drawer member 9 drives the protrusion 10 thereon to approach the corresponding support member 5.

[0040] In another embodiment proposed by the present invention, one end of the drawer member 9 is fixedly connected to the outer ring of the runner 11 and can be wound and unwound on the runner 11. Specifically, the end of the drawer member 9 connected to the runner 11 has bending flexibility while maintaining its length. Then, when the runner 11 rotates synchronously with the hook 2, the drawer member 9 can be wound and unwound on the runner 11 to slide relative to the skeleton 4. Further, when the rotation direction of the hook 2 points to another hook 2, the corresponding drawer member 9 is wound on the runner 11, that is, the drawer member 9 is wound and pulled, driving the protrusion 10 thereon to approach the corresponding support member 5.

[0041] In yet another embodiment proposed by the present invention, the runner 11 is detachably connected to the hook 2. Specifically, after the runner 11 and the hook 2 are detached, they are independently located on the inner and outer sides of the end face of the cover 1. At this time, both the runner 11 and the hook 2 can be separated from the cover 1, thereby further making the cover 1 independent and facilitating the cleaning or other operations of the cover 1.

[0042] As a preferred technical solution of this embodiment, a shaft body 14 is coaxially connected to the runner 11 and penetrates through the housing 1 in a rotating manner. A star shaft 15 is provided at the end of the shaft body 14 away from the runner 11. A rotating member 16 is coaxially connected to the rotating shaft of the hook 2. A star groove 17 matching the star shaft 15 is provided at the center of the rotating member 16. A nut is screwed onto the end of the star shaft 15 to limit and connect the rotating member 16. Specifically, a metal ring is preferably provided at the position where the housing 1 is penetrated by the shaft body 14, and the shaft body 14 passes through the metal ring, thereby stabilizing the position and rotational relationship of the shaft body 14 relative to the housing 1; the maximum outer diameter of the star shaft 15 is smaller than the outer diameter of the shaft body 14, that is, the star shaft 15 can freely pass through the housing 1; the rotating member 16 is arranged outside the end face of the housing 1, and the outer diameter of the rotating member 16 is larger than the aperture of the opening through which the shaft body 14 passes through the housing 1; the hook 2 is arranged at the edge of the rotating member 16 and points perpendicular to the axis of the rotating member 16; the star shaft 15 passes through the star groove 17 to rotate synchronously with the rotating member 16; a bolt head is provided at one end of the star shaft 15 away from the shaft body 14, and fasteners such as nuts can be screwed thereon to limit the connection between the rotating member 16 and the shaft body 14. Further, marks are provided on the end face of the housing 1, and the star shaft 15 and the star groove 17 can be connected at multiple adjustable angles. When the hook 2 is installed on the housing 1, first install the runner 11 inside the housing 1 and cooperate with the pulling member 9. The pulling member 9 is in the initial position, that is, the convex portion 10 is away from the support member 5. Then, install the rotating member 16 and the hook 2. The rotating member 16 can be adjusted at multiple angles by means of the star shaft 15 and the star groove 17 so that the hook 2 corresponds or is close to corresponding to the mark on the housing 1. Then, fix the rotating member 16, thereby satisfying the accurate positioning of the hook 2 at the initial position during installation. Thus, the angle at which the hook 2 rotates under the tension of the tension spring 3 subsequently just drives the pulling member 9 to move a fixed length, so that the convex portion 10 just clamps the support member 5.

[0043] A manufacturing method of a supercharger heat shield for a diesel engine, based on the above-mentioned supercharger heat shield for a diesel engine, includes: each support member 5 is uniformly and movably arranged inside the skeleton 4. The skeleton 4 is bent so that the support member 5 is located inside the bend. The housing 1 is sleeved outside the skeleton 4 and connected to the skeleton 4. The skeleton 4 props up the housing 1 to maintain a three-dimensional state. Specifically, the housing 1 includes two end faces and an outer peripheral shielding face; the skeleton 4 has a certain bending elasticity, fits with the inner side of the outer peripheral shielding face of the housing 1, and matches in size, and can prop up the housing 1; the skeleton 4 and the housing 1 are detachable, that is, it is convenient to separate the housing 1 for cleaning or other operations.

[0044] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
