Description

Technical Field

[0001] The invention belongs to the technical field of automobile accessories, and in particular relates to an automobile air-conditioning pipeline connecting pressing plate. Background Art

[0002] The air conditioning system is an important part of the car. In the air conditioning pipeline of the car, a pressure plate is needed to connect the air conditioning and the pipeline. The pressure plate is directly pressed into the car body by fasteners such as screws, and the pressure plate is used to connect the pipeline, expansion valve, and compressor, thereby ensuring the normal operation of the air conditioning system. In the prior art, the air conditioning pipeline connection pressure plate, the inlet and outlet are generally arranged opposite each other. When the air conditioning pipeline is installed on the pressure plate, it can only be installed on both sides of the pressure plate. When encountering space limitations or when the pipeline needs to change direction, the adaptability is poor. Therefore, it is necessary to optimize the design of the air conditioning pipeline connection pressure plate. Summary of the invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes an automobile air conditioning pipeline connecting pressure plate.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A car air conditioning pipeline connection plate comprises a base body with a cavity, a connecting part is arranged on the upper side of the base body, and a connecting hole is arranged on the connecting part; a connecting head is arranged on the front side wall of the base body, and the inner cavity of the connecting head is connected with the base body cavity; a docking port is arranged on the left side wall of the base body, and the docking port comprises a docking hole, and a docking depression is arranged on the outer surface of the left side wall corresponding to the docking hole; recesses are arranged on the inner side of the rear side wall, the inner side of the upper side wall, the inner side of the lower side wall, and the inner side of the right side wall of the base body, and filters are installed in the recesses; and a plurality of sealing grooves are arranged on the outer wall of the connecting head.

[0006] Furthermore, the sealing grooves are provided with 2-3 grooves.

[0007] Furthermore, the filter element includes a filter screen, and a gap is left between the filter screen and the bottom of the concave platform.

[0008] Furthermore, the axial direction of the connector and the axial direction of the docking port are perpendicular to each other.

[0009] Furthermore, the concave platform on the right side wall is arranged opposite to the docking port.

[0010] Furthermore, the base, the connector and the connecting part are an integrally formed structure.

[0011] Furthermore, the connecting portion includes a plate-shaped structure perpendicular to the base body.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The invention has a reasonable structural design. Since the inlet and outlet on the base are arranged vertically, the medium has a non-linear path in the inner cavity of the pressure plate. Therefore, the medium can contact the filter screens on the walls of the inner cavity to play a filtering role. While purifying impurities to the maximum extent, the filter screen will not be blocked to affect the flow of the medium. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0019] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] A car air conditioning pipeline connection pressure plate, such as Figure 1 and Figure 2 As shown, it includes a base 1 with a cavity, a connecting part 2 is provided on the upper side of the base, and a connecting hole 3 is provided on the connecting part; usually, the connecting part includes a plate-like structure perpendicular to the base. A connecting head 4 is provided on the front side wall of the base, and the inner cavity of the connecting head is connected to the base cavity; a docking port is provided on the left side wall 5 of the base, and the docking port includes a docking hole 6, and a docking sink 7 is provided on the outer surface of the left side wall corresponding to the docking hole. Usually, the docking sink is welded and fixed to the body structure to be docked. Preferably, the base, the connecting head and the connecting part are an integrally formed structure.

[0022] The inner side of the rear side wall 8, the inner side of the upper side wall 9, the inner side of the lower side wall, and the inner side of the right side wall 13 of the base body are all provided with concave platforms 10, and filter elements 11 are installed in the concave platforms; the outer wall of the connector is provided with several sealing grooves 12. As an example, the sealing grooves are provided with 2-3, and before connecting the pipeline, a sealing ring is installed in the sealing groove to ensure the sealing between the connecting plate and the pipeline.

[0023] The filter element includes a filter screen, and a gap is left between the filter screen and the bottom of the concave platform to allow the medium to enter the concave platform. When the medium enters the concave platform, it will be filtered by the filter screen, so that the filter screen can better play a filtering role. The axial direction of the connector is perpendicular to the axial direction of the docking port. The concave platform on the right side wall is arranged opposite to the docking port.

[0024] In the prior art, in the pressure plate structure with the inlet and outlet arranged opposite to each other, the inner cavity of the pressure plate is a linear medium channel, and the medium passes directly through the linear channel without filtering. Although there is a design in the prior art to install a filter screen in the inner cavity of the pressure plate, once the filter screen is blocked, it will directly cause the air conditioning system to not work normally or even be damaged. The pressure plate is generally connected by welding at least one end, which is difficult to remove and replace, so the maintenance cost after damage is very high. In the invention, the inlet and outlet are arranged non-oppositely, and the two are arranged at 90 degrees, which is not only more conducive to pipeline direction change, adapting to the spatial structure and improving adaptability, but also, because the medium passes through a non-linear path in the inner cavity of the pressure plate, it can contact the filter screens on the walls of the inner cavity, and the filter screens are installed in the concave platforms of each side wall, so while purifying impurities to the maximum extent, the filter screen will not be blocked to affect the flow of the medium.

[0025] The invention has a reasonable structural design. Since the inlet and outlet on the base are arranged vertically, the medium has a non-linear path in the inner cavity of the pressure plate. Therefore, the medium can contact the filter screens on the walls of the inner cavity to play a filtering role. While purifying impurities to the maximum extent, the filter screen will not be blocked to affect the flow of the medium.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
