Description

Technical Field

[0001] The utility model relates to the technical field of water pipe installation for new energy motor shells, in particular to an installation device for water pipes of new energy motor shells. Background Art

[0002] The motor cooling pipeline of new energy vehicles is an important part of the electric vehicle cooling system, mainly responsible for dissipating heat from high-power electrical equipment and high-power switching components to ensure that the motor operates within an appropriate temperature range. The cooling pipeline effectively takes away the excess heat from components such as the motor through circulating cooling water and dissipates the heat through heat dissipation devices such as radiators. Generally, cooling pipes are provided at the electric control part and the rotor part of new energy motors, and separate installation devices are required for installing the cooling pipes.

[0003] Generally, a fixed connection method of thread plus raw tape or seal ring plus bolt is adopted between the general cooling water pipe and the motor controller housing. For example, in the connection structure of the cooling water pipe of an electric vehicle motor controller disclosed in the Chinese patent publication number "CN205278608U", there are a motor controller housing and a stainless steel drawn water pipe. The motor controller housing is provided with a clearance hole, and the stainless steel drawn water pipe is inserted into the clearance hole and has an interference fit.

[0004] Currently, when installing the cooling water pipe of the motor controller, sometimes a bent pipeline needs to be installed. This bent pipeline is not convenient for positioning during installation. During fixation, it is necessary for the staff to hold the pipeline by hand for fixation. When installing, it is not convenient for the staff to align the bent pipeline with the installation opening on the motor controller housing, and it is very easy to shake and the installation difficulty is relatively large. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, such as inconvenient positioning during installation, the need for the staff to hold the pipeline by hand for fixation during fixation, the inconvenience for the staff to align the bent pipeline with the installation opening on the motor controller housing during installation, being very easy to shake and having a relatively large installation difficulty, etc., and to propose an installation device for water pipes of new energy motor shells.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design an installation device for water pipes of new energy motor shells. This device is connected to the water inlet of the shell and includes an installation pipe. It is characterized in that: one end of the installation pipe is fixed with a threaded pipe, the outer surface of the threaded pipe is threadedly connected with a threaded sleeve, connecting rods are hinged to the periphery of the installation pipe surface, and the other end of the connecting rod is hinged with an arc-shaped clamping plate. A clamping assembly is arranged between the threaded sleeve and the connecting rod, and a positioning mechanism is arranged at one end of the installation pipe.

[0008] Further, the clamping assembly includes a fixing ring rotatably connected to the surface of the threaded sleeve. Four convex blocks are fixed around the surface of the fixing ring, and through grooves are formed on the surfaces of the convex blocks. The connecting rods are movably connected to the through grooves.

[0009] Further, limiting rings are fixed on both sides of the fixing ring. Guide rails are arranged on the surface of the threaded sleeve, and the limiting rings are rotatably connected to the guide rails.

[0010] Further, the positioning mechanism includes a fixing frame fixed to the outer end of the installation pipe. A bidirectional screw rod is rotatably connected to the inner side of the fixing frame, and limiting plates are threadedly connected to both sides of the surface of the bidirectional screw rod.

[0011] Further, guide posts are fixed to the inner side of the fixing frame, and the limiting plates are slidably connected to the guide posts. The top end of the bidirectional screw rod penetrates through the fixing frame and extends to the outside of the fixing frame.

[0012] Further, positioning rings are fixed on both sides of the surface of the threaded sleeve. One of the positioning rings is fixed at the connection between the installation pipe and the threaded pipe.

[0013] The installation device for the water pipe of the new energy motor housing proposed by the utility model has the beneficial effects that: through the movement of the threaded sleeve on the outer surface of the threaded pipe, the fixing ring can be driven to move horizontally. The fixing ring can drive the four connecting rods and the arc-shaped clamping plates to clamp on the interface of the motor controller housing. And through the bidirectional screw rod, the two limiting plates can be driven to position and fix the bent pipe, which is convenient for installing the cooling water pipe at the electric control and rotor of the new energy motor.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-4 , an installation device for a water pipe of a new energy motor housing, which is connected to the water inlet of the housing 1. It includes an installation pipe 2, and is characterized in that: one end of the installation pipe 2 is fixed with a threaded pipe 3, and the outer surface of the threaded pipe 3 is threadedly connected with a threaded sleeve 4. Connecting rods 5 are hinged around the surface of the installation pipe 2, and the other ends of the connecting rods 5 are hinged with arc-shaped clamping plates 6. A clamping assembly 8 is arranged between the threaded sleeve 4 and the connecting rod 5, and a positioning mechanism 9 is arranged at one end of the installation pipe 2; through the movement of the threaded sleeve 4 on the outer surface of the threaded pipe 3, the fixing ring 81 can be driven to move horizontally, and the fixing ring 81 can drive the four connecting rods 5 and the arc-shaped clamping plates 6 to clamp on the interface of the motor controller housing, and the two limiting plates 93 can be driven by the bidirectional screw 92 to position and fix the bent pipeline, which is convenient for installing and fixing the cooling water pipe.

[0021] In this embodiment, the clamping assembly 8 includes a fixing ring 81 rotatably connected to the surface of the threaded sleeve 4. Protrusions 82 are fixed around the surface of the fixing ring 81, and through grooves 83 are formed on the surfaces of the protrusions 82. The through grooves 83 are movably connected with the connecting rods 5. The protrusions 82 on the surface of the fixing ring 81 can squeeze the connecting rods 5, and the connecting rods 5 drive the arc-shaped clamping plates 6 to quickly fix the installation pipe 2.

[0022] Furthermore, limiting rings 10 are fixed on both sides of the fixing ring 81, and guide rails 11 are arranged on the surface of the threaded sleeve 4, and the guide rails 11 are rotatably connected with the limiting rings 10. The limiting rings 10 can cooperate with the guide rails 11 to limit the fixing ring 81.

[0023] Still further, the positioning mechanism 9 includes a fixing frame 91, which is fixed to the outer end of the installation pipe 2. A bidirectional screw 92 is rotatably connected to the inner side of the fixing frame 91, and limiting plates 93 are threadedly connected to both sides of the surface of the bidirectional screw 92. The threads on the surface of the bidirectional screw 92 are of opposite square shapes, and the upper and lower limiting plates 93 can be driven to move towards each other simultaneously to position and fix the pipeline.

[0024] In addition, guide posts 12 are fixed to the inner side of the fixing frame 91, and the guide posts 12 are slidably connected with the limiting plates 93. The top end of the bidirectional screw 92 penetrates through the fixing frame 91 and extends to the outside of the fixing frame 91. The guide posts 12 can limit the limiting plates 93 and improve the movement stability of the limiting plates 93.

[0025] It should be noted that positioning rings 7 are fixed on both sides of the surface of the threaded sleeve 4. One side of the positioning ring 7 is fixed at the connection between the installation pipe 2 and the threaded pipe 3. The positioning ring 7 can limit the movement of the threaded sleeve 4, enabling it to move within a certain range and limit the stroke.

[0026] Working method: When installing the pipeline, the staff can align one end of the device with the position where installation is required. Then, the staff rotates the threaded sleeve 4 by hand. The threaded sleeve 4 can rotate on the surface of the threaded pipe 3 and thus move horizontally. The convex block 82 on the surface of the threaded sleeve 4 can gradually squeeze the connecting rod 5, thereby driving the arc-shaped clamping plate 6 to simultaneously squeeze towards the center and clamp on the connecting pipe to be installed. After that, the staff can insert the curved pipeline to be installed and tighten the bidirectional screw 92 by hand. The bidirectional screw 92 can drive the two limiting plates 93 to move towards each other to position and fix the curved pipeline. At this time, the staff can carry out stable installation to avoid the pipeline shifting in position.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
