Description

Technical Field

[0001] The utility model relates to the technical field of driver controllers, in particular to a driver controller alert pressing device. Background Art

[0002] The subway and locomotive driver controller is generally composed of a key switch, a mode selection handle, and a traction brake handle. The traction brake handle is generally required to be integrated with a warning function, which is a device to prevent the vehicle from automatically braking when the driver leaves the traction brake handle or fails to trigger the warning function due to falling asleep or unexpected circumstances.

[0003] The warning device needs to be triggered by the driver all the time when the vehicle is towing and braking in order to maintain normal driving of the vehicle.

[0004] Currently, the driver controller warning devices on the market are generally hand-held and hand-pressed types. The warning signal output cables of these two warning devices under the traction brake handle will swing with the forward and backward push and pull of the traction brake handle. The warning signal output cables are prone to fatigue fracture or wear and tear with the surrounding frame during the back and forth swing.

[0005] The traction brake handle of the driver controller is the main device for the driver to control the traction and braking force of the train. It also needs to have an alert function. The alert function is a device to ensure that the driver is always alert. It provides a signal to the vehicle by integrating a trigger device on the traction brake handle. When the driver operates the traction brake handle to control the vehicle, the alert device must be triggered at all times. If the driver leaves the traction brake handle due to other reasons, the vehicle will alarm according to the signal fed back by the alert device. If the alert device is not triggered after a period of time, the vehicle will brake and stop the vehicle.

[0006] There are several existing technical solutions:

[0007] 1. Install the micro switch directly inside the handle, and trigger the micro switch action by squeezing the bulge on the handle, so as to feed back the switch signal to the vehicle; the connection line of the micro switch needs to be led out from the inside of the handle, which inevitably causes the wiring harness to swing with the handle;

[0008] 2. Install a switch under the handle. When the traction brake handle is pressed down, the internal push rod directly presses the switch to operate. When the warning trigger rod is pressed down, the warning signal switches on both sides are triggered. In the existing structure, since the warning trigger rod swings back and forth with the traction brake handle, the warning signal switch must also swing back and forth with the traction brake handle, causing the lead wire of the warning signal switch to swing back and forth with the handle, posing a risk of wear and breakage. Utility Model Content

[0009] The purpose of the utility model is to provide a controller alert pressing device to solve the problems raised in the above background technology.

[0010] To achieve the above object, the utility model provides the following technical solution: a driver controller alert pressing device, comprising a support plate, a warning switch mounting bracket is installed at the bottom of the support plate, a warning switch is installed on the warning switch mounting bracket, and a warning switch roller is installed on the top of the warning switch;

[0011] A cam is arranged on the top of the alert switch roller, a warning push rod is connected to the top of the cam, a traction brake handle rod is connected to the outer surface of the alert push rod, and the top of the alert push rod extends outside the traction brake handle rod and is provided with a handle.

[0012] Preferably, a spring located in the traction brake handle rod is sleeved on the alert push rod, and one end of the spring is fixed to the inner wall of the traction brake handle rod, and the other end of the spring is installed on the alert push rod.

[0013] Preferably, the alert switch roller is matched with a cam.

[0014] Preferably, a rotary bearing is installed on one side of the support plate, and one side of the traction brake handle rod is installed on the rotary bearing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1) The installation method of triggering the alarm switch by a cam connected to the alarm push rod;

[0017] 2) After the alert switch is pressed and activated, the outer arc surface of the cam is concentric with the rotary bearing of the traction brake handle rod;

[0018] The problem that the warning signal output cable swings back and forth with the traction brake handle is solved, so that when the driver operates the traction brake handle, the warning device can be operated at various angles while the warning signal cable does not swing with the traction brake handle, thus solving the problem that the warning signal cable is easy to wear and break.

[0019] The utility model has a strong, simple and reliable structure with integrated alert function; the switch of the solution is fixedly installed and will not rotate with the traction brake handle, and its connection harness will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a technical solution: a controller alert pressing device, comprising a support plate 8, a warning switch mounting bracket 7 is installed at the bottom of the support plate 8, a warning switch 6 is installed on the warning switch mounting bracket 7, and a warning switch roller 5 is installed on the top of the warning switch 6;

[0026] A cam 4 is arranged on the top of the warning switch roller 5, and a warning push rod 3 is connected to the top of the cam 4. A traction brake handle rod 1 is connected to the outer surface of the warning push rod 3, and the top of the warning push rod 3 extends to the outside of the traction brake handle rod 1 and is equipped with a handle 9.

[0027] In the utility model, a spring 2 located in the traction brake handle rod 1 is sleeved on the alert push rod 3, and one end of the spring 2 is fixed on the inner wall of the traction brake handle rod 1, and the other end of the spring 2 is installed on the alert push rod 3.

[0028] In the utility model, the alert switch roller 5 is matched with the cam 4.

[0029] In the utility model, a rotary bearing is installed on one side of the support plate 8, and one side of the traction brake handle rod 1 is installed on the rotary bearing.

[0030] The working principle of the utility model is as follows: the traction brake handle rod 1 rotates around its rotary bearing, the handle 9 is connected to the alert push rod 3, the cam 4 is connected to the alert push rod 3, the alert switch roller 5 is installed on the alert switch 6, the alert switch 6 is installed on the alert switch mounting bracket 7, and the alert switch mounting bracket 7 is installed on the support plate 8;

[0031] When the handle 9 is pressed, the alert push rod 3 and the cam 4 are pressed downward, and the cam 4 is pressed downward to push the alert switch roller 5 downward, so that the internal contacts of the alert switch 6 are closed and the alert switch signal is output;

[0032] After the cam 4 is pressed down, its outer cylindrical surface is concentric with the rotary bearing of the traction brake handle rod 1, so that no matter what angle the traction brake handle rod 1 rotates to, the compression amount of the cam 4 on the alert switch roller 5 remains unchanged.

[0033] With the above structure, when the traction brake handle bar 1 rotates at any angle of the traction brake, only the cam 4 rotates with the handle bar, while keeping the internal contacts of the alert switch 6 closed, so that the alert switch 6 does not rotate with the rotation of the traction brake handle bar 1, and its signal output line does not rotate with the rotation of the traction brake handle bar 1;

[0034] When the handle 9 is not pressed, the handle 9, the alert push rod 3 and the cam 4 are bounced up by the spring 2, so that the alert switch roller 5 is bounced up and restored by the internal recovery spring of the alert switch 6, so that the internal contacts of the alert switch 6 are disconnected and restored to the initial state.
