Description

Technical Field

[0001] This utility model relates to a driver controller, specifically an IPX5 protected driver controller. Background Technology

[0002] The driver controller, as the master controller used by drivers to operate high-speed trains, national railway locomotives, and subway vehicles, mainly functions to convert manually operated mechanical signals into electrical signals to control the traction, braking, and operating modes of the train. For example, it applies traction commands to start the vehicle, sends braking commands to brake the vehicle, and determines the train operating mode to adjust speed. The driver controller is built in a modular manner, and the platform is mature, reliable, has a low failure rate, and is easy to maintain.

[0003] Currently, the driver controllers used on domestically produced high-speed trains, national railway locomotives, and subway vehicles in China have a low overall protection level because their live parts are not equipped with protective covers. Their overall protection level is IPX0. Once the live parts of the driver controller are exposed to sudden situations such as water immersion or spraying, it is easy to cause short circuits or abnormal discharges in the live parts of the driver controller, thereby affecting driving safety. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of the low overall protection level of existing driver controllers, and to provide an IPX5 protected driver controller.

[0006] A driver controller with IPX5 protection is special in that:

[0007] Includes a base plate, a protective cover mounted on the base plate and a fourth support plate, as well as button components;

[0008] The protective cover is closed at one end and open at the other end. The open end is tightly fitted with the fourth support plate to form a sealed structure, and a wire outlet hole is provided on the closed end.

[0009] The top of the protective cover is provided with a round hole, and the periphery of the round hole is provided with a plurality of teardrop-shaped concave holes, which are frustum-shaped holes; a lower boss is provided on the inner wall surface of the protective cover corresponding to the small end of each frustum-shaped hole, and each frustum-shaped hole is located in the middle of a lower boss.

[0010] The button mounting plate of the button component has multiple countersunk holes corresponding to the teardrop-shaped recesses on its upper surface, and the countersunk holes are threaded holes;

[0011] The button mounting plate is fixed to the base plate by multiple mounting posts and mounting screws. The mounting posts are located between the base plate and the upper inner wall of the protective cover. The lower end of the posts is fixed to the base plate, and the upper end is fixed to the lower side of the button mounting plate by the first screw.

[0012] The button mounting plate is fixed to the inner top of the protective cover by waterproof screws passing through the teardrop-shaped recess and the countersunk hole. The lower boss extends into the submerged section of the countersunk hole, and the length of the lower boss is less than the depth of the submerged section. The inner top of the button mounting plate, the side wall of the submerged section, and the outer side wall of the lower boss form an annular sealing space, and a waterproof sealing ring is provided in the annular sealing space.

[0013] The button cap of the button extends out of the circular hole provided on the top of the protective cover.

The two together form the lower bottom surface of the submerged section. The inner top side of the button mounting plate, the side wall of the submerged section, the outer side wall of the lower boss, and the lower bottom surface of the submerged section form an annular sealing space. The outer periphery of the waterproof sealing ring abuts against the inner top side of the button mounting plate, the side wall of the submerged section, the outer side wall of the lower boss, and the lower bottom surface of the submerged section.

[0017] Furthermore, let L be the length of the lower boss and H be the depth of the submerged section, then 1 / 2H ≤ L ≤ 3 / 4H.

[0018] Furthermore, the outlet hole has an arched structure, with a wire clamp connected to the protective cover on its periphery. The wire clamp has an outlet washer, which has an inverted U-shaped structure with square holes on both sides.

[0047] The working principle of the driver controller in this embodiment is as follows:

[0048] When the driver turns the handle 31 of the driver controller, the camshaft is driven to rotate through the gear transmission. The rotation of the camshaft causes the cam to trigger the quick-action switch 7. The quick-action switch 7 outputs traction and braking switch commands. At the same time, the two encoders 8, which are coaxially connected to the camshaft, output traction and braking encoded signals. When the handle is turned to the emergency brake, the emergency brake switch outputs an emergency brake command.

[0049] This embodiment of the driver controller features a compact structure, small size, and light weight, with a mounting height of only 93mm, making it suitable for installation on control panels with strict height requirements. The entire driver controller is mounted under the control panel, with only two operating mechanisms: the traction brake handle and the mode button. This facilitates the overall layout of the control panel. A protective cover is added to the energized areas of the driver controller, enclosing all energized components. This effectively prevents energized parts from being exposed to extreme conditions such as water immersion or spraying, thus achieving an IPX5 protection level for the entire energized parts of the driver controller, ensuring the stable and safe operation of locomotives and rolling stock.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
