Description

Technical Field

[0001] The utility model relates to the technical field of generator structures, in particular to a vehicle generator. Background Art

[0002] A vehicle generator is a generator that is installed and fixed on a vehicle for use. The engine in the generator needs to be lubricated with oil. After a period of use, the oil needs to be replaced, so the oil needs to be drained from the engine to facilitate refilling with new oil. Existing vehicle generators are generally produced by appropriately improving the mounting frame of a portable generator, and the oil discharge hole of a portable generator is generally set on the side of the generator to facilitate the discharge of oil by tilting the generator. Therefore, the oil discharge hole of existing vehicle generators is generally also set on the side of the generator.

[0003] Chinese patent document CN219910947U discloses a vehicle-mounted generator set that is convenient for adding and draining oil, including a base and an engine structure arranged on the base, the engine structure including an engine group installed on the base and a main control box electrically connected to the engine group, the engine group having an oil filling port, an oil circulation pipeline connected to the oil filling port, and an engine oil pan connected to the oil circulation pipeline, the engine oil pan is provided with an oil pressure sensor, and the oil pressure sensor is electrically connected to the main control box; the engine group has an oil pan oil discharge nozzle and an oil drain valve for draining oil, the oil pan oil discharge nozzle and the oil drain valve have a height difference, and the oil drain valve is a one-way valve. By setting the oil pan oil discharge nozzle and the oil drain valve, when draining oil, the joint is connected to the oil drain valve, and the oil will be discharged from the oil pan oil discharge nozzle, and the subsequent oil filling operation can be performed after the oil is discharged.

[0004] In the above-mentioned prior art solutions, the oil discharge position of the generator is still set on the side of the bottom of the generator, and the oil nozzle and the oil discharge valve need to work together to discharge the oil, which is more troublesome to operate. In addition, the method of discharging the oil from the side of the generator is adopted. Since the generator is installed and fixed on the frame, it is necessary to control the vehicle to make the side of the generator that discharges the oil be in a lower position when discharging the oil, otherwise it is easy to cause a large amount of oil residue, so that a large amount of old oil is mixed into the new oil, affecting the effect after the oil is replaced, thereby affecting the normal use of the generator. As a result, the maintenance operation of replacing the oil of the vehicle generator is more complicated. Utility Model Content

[0005] The utility model aims to provide a vehicle generator to solve the problem of poor convenience in discharging oil from the vehicle generator in the prior art.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a vehicle generator, including a shell bottom plate, to which an engine is connected, a downward oil drain hole is provided at the bottom of the engine, an oil drain plug is detachably connected to the oil drain hole, and an oil discharge hole connected to the oil drain hole is provided on the shell bottom plate.

[0007] The beneficial effect of this basic solution is that: by adopting such a setting, the generator can directly discharge the engine oil at the bottom, so that the oil can be discharged without removing the generator from the vehicle, thereby improving the convenience of generator maintenance.

[0008] Preferably, the oil discharge hole is located directly below the oil drain hole. With such a configuration, the oil discharged from the oil drain hole can directly pass through the oil discharge hole under the action of gravity, which is conducive to the rapid discharge of oil from the generator; at the same time, the oil discharge hole is also convenient for operation, which is conducive to improving maintenance convenience.

[0009] Preferably, a plug is detachably connected to the oil discharge hole. With such a configuration, the plug seals the oil discharge hole, thereby preventing debris from entering the housing through the oil discharge hole and interfering with the normal operation of the generator, thereby facilitating improving the reliability of the generator.

[0010] Preferably, the diameter of the oil discharge hole is larger than that of the oil drain hole. With such a configuration, the diameter of the oil column formed by the oil discharged from the oil drain hole is smaller than the diameter of the oil discharge hole, thereby reducing the oil contacting the edge of the oil discharge hole, and further reducing the oil stains formed by the oil on the bottom plate of the housing, which is conducive to reducing the subsequent cleaning work.

[0011] Preferably, the oil drain plug is threadably connected to the engine. This arrangement is conducive to improving the convenience of disassembly and assembly of the oil drain plug.

[0012] Preferably, the plug is clamped with the bottom plate of the housing. Such a configuration is helpful to improve the convenience of disassembly and assembly of the plug.

[0013] The utility model has the following beneficial effects:

[0014] Compared with the prior art, the present solution allows the generator to directly discharge the engine oil at the bottom, thereby eliminating the need to remove the generator from the vehicle or adjust the position of the generator through the vehicle to achieve oil discharge, thereby improving the convenience of generator maintenance.

[0018] The following is further described in detail through specific implementation methods:

[0019] The reference numerals in the drawings of the specification include: engine 1, housing bottom plate 2, plug 3, oil drain plug 4, guide nozzle 5.

[0020] The embodiment is basically as shown in the attached Figure 1 , Figure 2 and Figure 3 As shown: A vehicle generator includes a housing bottom plate 2, to which an engine 1 is connected. A vertical downward drain hole is provided at the bottom of the engine 1, and a drain plug 4 is detachably connected to the drain hole. In this embodiment, the drain plug 4 is preferably threadedly connected to the engine 1. An oil discharge hole connected to the oil discharge hole is provided on the housing bottom plate 2, so that the oil discharged from the oil discharge hole of the engine 1 can be discharged to the outside of the generator through the oil discharge hole. In this embodiment, the oil discharge hole is located directly below the oil discharge hole. The aperture of the oil discharge hole is larger than the aperture of the oil discharge hole, so that the oil discharged from the oil discharge hole can flow directly through the oil discharge hole and reduce contact with the hole wall of the oil discharge hole. At the same time, such a setting also facilitates the disassembly and assembly of the drain plug 4 at the oil discharge hole through the oil discharge hole. In this embodiment, a plug 3 is detachably connected to the oil discharge hole. Preferably, the plug 3 is snap-fitted with the housing bottom plate 2. The plug 3 is made of a flexible material, and the plug 3 is inserted into or removed from the oil discharge hole by deformation of the plug 3. In this embodiment, the engine is also covered with an air guide cover, and a guide nozzle 5 facing the oil discharge hole is provided at the bottom of the air guide cover, and the lower end of the guide nozzle 5 is protruding downward, which is conducive to avoiding the phenomenon of oil backflow from the outer wall of the lower end of the guide nozzle 5, thereby reducing the subsequent cleaning work.

[0021] By adopting this solution, the oil of the engine 1 can be directly discharged at the bottom of the generator, so that the oil can be discharged without removing the generator from the vehicle or adjusting the position of the generator through the vehicle, thereby improving the maintenance convenience of the generator.

[0022] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
