Technical Field
[0001] The utility model relates to a lower vehicle lamp for engineering machinery, belonging to the technical field of vehicle lamp lighting. Background Art
[0002] At present, many domestic and foreign construction machinery such as excavators and cranes are not equipped with exit lights. Conventional cab top working lights and front combination lights can only illuminate the driving road and working surface, and cannot provide the lighting needs of the platform and stairs of the machinery. When the driver goes up and down the cab through the stairs and platforms at night, he can only use other lighting tools, such as flashlights, mobile phones, etc., which is not very convenient and is easy to step on air or bump into the body, increasing the potential for accidents. Utility Model Content
[0003] The technical problem to be solved by the utility model is that most of the existing engineering machinery are not equipped with exit lights, and when the driver goes up and down the cab through stairs and platforms, he can only use other lighting tools, such as flashlights, mobile phones, etc., which is not very convenient and is easy to step on air or bump into the body, increasing the problem of potential accidents.
[0004] In order to solve the above technical problems, the utility model provides an exit light for engineering machinery, which can automatically illuminate when the driver turns off the engine and exits the vehicle, and automatically turn off after a certain period of time, so as to ensure the driver's safe exit.
[0005] In order to achieve the above technical objectives and the above technical effects, this application is implemented through the following technical solutions:
[0006] A lower lamp for engineering machinery comprises an lower lamp body, a fuse and a time delay relay. The lower lamp body is arranged on the body of the engineering machinery and ensures that the light beam can irradiate the engineering machinery platform and the light ladder. The lower lamp body is electrically connected to the battery of the engineering machinery. The fuse and the time delay relay are electrically connected between the battery and the lower lamp body in sequence, and are used to protect the circuit and control the on-off of the electrical connection between the lower lamp body and the battery.
[0007] Preferably, the manual power main switch of the engineering machinery is connected in series between the lower lamp body and the negative electrode of the battery, and the ignition switch of the engineering machinery is connected in series between the positive electrode of the battery and the delay relay.
[0008] Furthermore, the ignition switch is divided into four gears, namely OFF lock gear, flameout gear, power-on gear and start gear. When the car is parked and the engine is turned off, the ignition switch is adjusted to the OFF lock gear, the lower lamp body is lit, and the lower lamp body is turned off by controlling the delay relay.
[0009] Furthermore, the time of the delay relay is generally set to 30s.
[0010] Furthermore, a power relay is electrically connected between the battery and the time delay relay.
[0011] Furthermore, a fuse 2 is connected in series between the ignition switch and the power relay, a fuse 3 is connected in series between the power relay and the fuse, and a fuse 4 is connected in parallel between the fuse 2 and the fuse 3.
[0012] The utility model provides a lower vehicle lamp for engineering machinery, which has the following advantages:
[0013] The utility model of the engineering machinery exit light is installed in a suitable position so that the light beam can illuminate the platform and the stairs. When the driver stops the vehicle temporarily for work at night, in order to facilitate leaving the vehicle, the driver can turn off the engine and pull out the key according to normal operating habits. At this time, the exit light automatically lights up, the platform and the footrest are illuminated, and the driver closes the cab door and leaves the vehicle. After a delay of a period of time (the value can be set) through the delay relay, the staircase light automatically turns off, which solves the need for the driver to see the outline of the cab and the exit pedal clearly when leaving the cab for operation in a dim environment. The operation is simple, economical and practical, and the possibility of accidents is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technical personnel in the field without creative work are within the scope of protection of the present utility model.
[0020] Reference Figure 1-Figure 3A light for getting off a vehicle for construction machinery comprises a light body 1, a fuse 2 and a time delay relay 3. The light body 1 is fixedly mounted on a vehicle body of the construction machinery 4 by bolts and ensures that the light beam can irradiate the platform and the light ladder of the construction machinery 4. The light body 1 is electrically connected to a battery 5 of the construction machinery 4. The fuse and the time delay relay 3 are electrically connected between the battery 5 and the light body 1 in sequence. The time of the time delay relay 3 is generally set to 30s, which is used to protect the circuit and control the on-off of the electrical connection between the light body 1 and the battery 5. At the same time, it is ensured that the light body 1 is always in a lighting state when the driver gets off the vehicle and reaches the ground, and is extinguished after the driver gets off the vehicle, thereby saving power.
[0021] Furthermore, the manual power main switch 6 of the engineering machinery 4 is connected in series between the lower lamp body 1 and the negative pole of the battery 5, and the ignition switch 7 of the engineering machinery 4 is connected in series between the positive pole of the battery 5 and the delay relay 3, thereby realizing the control of the lighting of the lower lamp body 1 through the gain and loss of power of the delay relay 3. In this embodiment, the electrical connection between the lower lamp body 1 and the manual power main switch 6, the ignition switch 7 and the battery 5 is the prior art and will not be elaborated in detail.
[0022] Furthermore, the ignition switch 7 is divided into four gears, namely OFF lock gear, flameout gear, power-on gear and start gear. When the car is parked and the engine is turned off, the ignition switch 7 is adjusted to the OFF lock gear, the lower lamp body 1 is lit, and the lower lamp body 1 is turned off by controlling the delay relay 3.
[0023] Furthermore, a power relay 8 is electrically connected between the battery 5 and the time delay relay 3 to play a role in circuit protection and equipment protection, thereby ensuring the safe operation of the equipment.
[0024] Reference Figure 3 In a further embodiment, a fuse 2 9 is connected in series between the ignition switch 7 and the power relay 8, a fuse 3 10 is connected in series between the power relay 8 and the fuse 1 2, and a fuse 4 11 is connected in parallel between the fuse 2 9 and the fuse 3 10, and the safety of circuit operation is further ensured by multiple fuses.
[0025] The use principle of the utility model of a lower vehicle lamp for engineering machinery is as follows:
[0026] The working state of the delay relay 3 is normally closed within 30 seconds after power failure. When the ignition switch 7 is in the power-on position, the manual power main switch 6 is turned on, the magnet end of the delay relay 3 is energized, so that the relay control end remains disconnected, and the lower lamp body 1 is not energized; when the ignition switch 7 is in the OFF position, the manual power main switch 6 is turned on, the magnet end of the delay relay 3 loses power, so that the control end of the delay relay 3 remains closed for 30 seconds, and the lower lamp is energized. After 30 seconds, the control end of the delay relay 3 is disconnected, and the lower lamp loses power.
[0027] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
