Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning air ducts, and particularly relates to an automobile air-conditioning air duct for suppressing blow molding deformation. Background Technique

[0002] Automobile ventilation system: Its function is to ensure indoor ventilation when the automobile is running, that is, to continuously rush fresh air into the automobile interior and drive out the harmful gases mixed with dust, carbon dioxide and those from the engine. In cold winter, the fresh air also needs to be heated to ensure a suitable indoor temperature. The automobile ventilation system needs to use air ducts to convey air. Since the air ducts are relatively soft by themselves, they are prone to deformation of the branch ducts due to excessive wind force during operation, thus affecting the air conveyance efficiency. Therefore, a method for preventing deformation needs to be set for the air ducts to avoid deformation.

[0003] For the existing automobile air-conditioning air ducts for suppressing blow molding deformation, due to insufficient anti-deformation performance, the pipes are prone to deformation due to excessive wind force during operation, thus affecting the air conveyance efficiency.

Grooves are formed inside the installation cylinders. Springs are fixedly connected to the bottom of the inner walls of the grooves. Connection plates are fixedly connected to the tops of the springs. Dampers are fixedly connected to both ends of the top of the installation plates. When the inner duct conveys air, due to excessive wind force, the inner wall of the inner duct will be squeezed, and thus the connection plate will be squeezed. The spring is squeezed through the connection plate. The telescopic rebound of the spring is used to absorb and release the kinetic potential energy generated during air conveyance, so as to reduce the pressure generated during air conveyance as much as possible, and thus avoid the deformation of the inner duct and the outer duct due to excessive wind force as much as possible. The problem of continuous shaking due to the spring during air conveyance is avoided as much as possible through the provided dampers.

[0008] Preferably, a connection plate is fixedly connected to the top of the inner duct, and the top of the damper is fixedly connected to the outer side wall of the inner duct. The inner duct is provided to facilitate air conveyance.

[0009] Preferably, a filter is fixedly connected to the inner wall of the inner pipe. By arranging the filter on the inner wall of the inner pipe, impurities in the wind can be filtered, thereby avoiding as much as possible that the inner pipe is blocked due to excessive impurities in the wind.

[0010] Preferably, both ends of the outer pipe are fixedly connected with a clamping assembly, and the clamping assembly includes a fixing ring, a turning handle, a threaded rod, a bearing, a clamping block and a clamping groove.

[0012] Preferably, the bottom end of the threaded rod is rotatably connected to a bearing, and the bottom of the bearing is fixedly connected to a clamping block, and the rotation of the threaded rod drives the rotation of the bearing, thereby moving the clamping block to the outer wall of the connection.

[0016] 1. The automobile air-conditioning duct for suppressing blow molding deformation achieves the effect of anti-deformation through the coordinated use of the mounting plate, mounting cylinder, groove, spring, connecting plate and damper. When the pipeline starts to work and deliver air, it will squeeze the inside of the pipeline, so that the pipeline will squeeze the connecting plate, and the spring will be squeezed through the connecting plate. The pressure generated during air delivery is absorbed and released through the expansion and contraction rebound of the spring, so as to reduce the pressure to the minimum as much as possible, so as to avoid the problem of pipeline deformation caused by excessive wind force during air delivery as much as possible, and the problem of continuous shaking caused by the spring is avoided as much as possible through the provided damper, thereby improving the practicality of the air duct.

[0017] 2.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] The preferred embodiment of the automotive air-conditioning duct that suppresses blow molding deformation provided by the present utility model is as Figures 1 to 5As shown: An automotive air-conditioning air duct for suppressing blow molding deformation, including an outer duct 1. Installation plates 6 are equidistantly arranged around the inner wall of the outer duct 1. Installation cylinders 7 are equidistantly arranged on the top of the installation plates 6. A groove 10 is formed inside the installation cylinder 7. A spring 8 is fixedly connected to the bottom of the inner wall of the groove 10. The top of the spring 8 is fixedly connected to a connecting plate 9. Dampers 5 are fixedly connected to both ends of the top of the installation plate 6. When the inner duct 3 conveys air, due to excessive wind force, the inner wall of the inner duct 3 will be squeezed, thereby squeezing the connecting plate 9. The spring 8 is squeezed through the connecting plate 9. The expansion and rebound of the spring 8 are used to absorb and release the kinetic potential energy generated during air conveyance, thereby reducing the pressure generated during air conveyance as much as possible, and thus avoiding the deformation of the inner duct 3 and the outer duct 1 caused by excessive wind force as much as possible. The problem of continuous shaking caused by the spring 8 during air conveyance is avoided as much as possible through the provided dampers 5.

[0027] In this embodiment, the top of the connecting plate 9 is fixedly connected to an inner duct 3. The top of the damper 5 is fixedly connected to the outer side wall of the inner duct 3. The inner duct 3 is provided to facilitate the conveyance of air.

[0028] Embodiment 2

[0029] Based on Embodiment 1, the preferred embodiment of the automotive air-conditioning air duct for suppressing blow molding deformation provided by the present utility model is as Figures 1 to 5 shown: A filter screen 4 is fixedly connected to the inner wall of the inner duct 3. By providing the filter screen 4 on the inner wall of the inner duct 3, it is convenient to filter impurities in the air, thereby avoiding blockage inside the inner duct 3 caused by excessive impurities in the air as much as possible.

[0030] In this embodiment, clamping assemblies 2 are fixedly connected to both ends of the outer duct 1. The clamping assembly 2 includes a fixing ring 201, a turning handle 202, a threaded rod 203, a bearing 204, a clamping block 205, and a clamping groove 206. By providing the clamping assembly 2, it is convenient to fix the connection between the ducts, thereby avoiding the risk of the ducts falling off during operation as much as possible.

[0031] Furthermore, threaded rods 203 are threadedly connected to the periphery of the outer side wall of the fixing ring 201. The top of the threaded rod 203 is fixedly connected to the turning handle 202. By connecting the fixing ring 201 to the connection point and rotating the turning handle 202, the rotation of the threaded rod 203 is driven.

[0032] Even further, the bottom end of the threaded rod 203 is rotatably connected to a bearing 204. The bottom of the bearing 204 is fixedly connected to a clamping block 205. By using the rotation of the threaded rod 203, the rotation of the bearing 204 is driven, and thus the clamping block 205 is moved to the outer side wall of the connection point.

[0033] In addition, a clamping groove 206 is provided at the bottom of the clamping block 205, and the connection is fixed by the clamping groove 206, so as to avoid the risk of the outer pipe 1 and the inner pipe 3 falling off the connection during operation, so as to make the pipe and the connection fixed more tightly.

[0034] When in use, first connect the fixing ring 201 to the connection, and drive the threaded rod 203 to rotate by turning the turning handle 202, thereby driving the bearing 204 to rotate, so as to move the clamping block 205 to the outer wall of the connection, and fix the connection through the clamping groove 206, so as to avoid the risk of the outer pipe 1 and the inner pipe 3 falling off from the connection during work as much as possible, and to facilitate filtering impurities in the wind by arranging the filter screen 4 on the inner wall of the inner pipe 3, so as to avoid the inner pipe 3 from being damaged by excessive impurities in the wind. The inside of the inner pipe 3 is blocked. When the inner pipe 3 is conveying air, the wind force is too strong to squeeze the inner wall of the inner pipe 3, thereby squeezing the connecting plate 9, and the spring 8 is squeezed by the connecting plate 9. The dynamic potential energy generated during the air delivery is absorbed and released by the expansion and contraction rebound of the spring 8, so as to reduce the pressure generated during the air delivery as much as possible, so as to avoid deformation of the inner pipe 3 and the outer pipe 1 caused by excessive wind force as much as possible, and the damper 5 is provided to avoid the problem of continuous shaking of the spring 8 during air delivery as much as possible.

[0035] In summary, the automobile air-conditioning duct capable of suppressing blow molding deformation is convenient for fixing the duct and the joint, and at the same time avoids the problem of deformation of the duct due to excessive wind force when the duct is conveying air as much as possible.
