Description

Technical Field

[0001] The utility model relates to a vehicle-mounted generator, in particular to a vehicle-mounted generator. Background Art

[0002] A vehicle-mounted generator is a generator installed on a vehicle, usually on the frame on the side of the vehicle, for easy operation and use.

[0003] Chinese patent document CN210858944U discloses a variable frequency silent generator, including a muffler air guide cover, the muffler air guide cover includes a muffler air guide cover body, a muffler body is arranged in the inner cavity of the muffler air guide cover body, the muffler air guide cover body includes an inner shell and an outer shell, the edge of the inner shell is connected to the edge of the outer shell to form a muffler air guide cover body with an internal cavity; the muffler air guide cover body is connected to the shell assembly of the engine.

[0004] In the above scheme, the air outlet of the muffler air guide cover is located on the side of the muffler air guide cover away from the engine, so that the hot air after cooling the engine and the muffler is discharged from the side of the muffler air guide cover. When such a generator is installed in a motorhome for use, it is found that the temperature around the generator will be relatively high, which may easily lead to poor heat dissipation effect of the generator, thereby affecting the normal use of the generator. Utility Model Content

[0005] The utility model aims to provide a vehicle-mounted generator to solve the problem of poor heat dissipation when the generator is installed on a recreational vehicle.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a vehicle-mounted generator, including a frame, an engine is mounted on the frame, a muffler is connected to the exhaust end of the engine, the outer cover of the muffler is provided with a silencer air guide cover, the silencer air guide cover is provided with an air outlet, and the air outlet is located at the bottom of the silencer air guide cover.

[0007] The beneficial effect of this basic solution is that: by adopting such a setting, the silencer air guide cover discharges the hot air after cooling the silencer from the bottom, so that when the generator is installed on the frame, the hot air discharged from the air outlet is directed toward the ground, which is beneficial to improving the heat dissipation effect of the generator.

[0008] Preferably, the frame includes a bottom plate, and a ventilation hole opposite to the air outlet is arranged on the bottom plate. With such an arrangement, the hot air discharged from the muffler air guide cover will quickly dissipate after passing through the ventilation hole and will not enter the interior of the generator, thereby facilitating the heat dissipation effect of the generator.

[0009] Preferably, the noise-absorbing air guide cover is connected with a bracket, and the bracket is fixedly connected to the bottom plate. With such an arrangement, it is convenient to support and fix the noise-absorbing air guide cover.

[0010] Preferably, the exhaust port of the muffler is arranged in the same direction as the air outlet. With such an arrangement, the hot air discharged from the muffler and the hot air discharged from the air outlet are in the same direction, which is conducive to further improving the heat dissipation effect of the generator.

[0011] Preferably, the exhaust port of the muffler is located at the bottom of the generator. With such an arrangement, the hot air discharged from the muffler is diffused from the bottom of the generator, which is conducive to reducing the impact of the hot air on the generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a schematic diagram of a vehicle-mounted generator embodiment. DETAILED DESCRIPTION

[0013] The following is further described in detail through specific implementation methods:

[0014] The reference numerals in the drawings of the specification include: a sound-absorbing air guide cover 1, a bottom plate 2, an exhaust port 3, an air outlet 4, and a bracket 5.

[0015] The embodiment is basically as shown in the attached Figure 1 As shown: A vehicle-mounted generator includes a frame, an engine is mounted on the frame, and a muffler is connected to the exhaust end of the engine. In this embodiment, the frame includes a bottom plate 2, and the engine is connected to the bottom plate 2. The outer cover of the muffler is provided with a muffler air guide hood 1, and the muffler air guide hood 1 is provided with an air outlet 4. In this embodiment, the air outlet 4 is located at the bottom of the muffler air guide hood 1. The bottom plate 2 is provided with a ventilation hole opposite to the air outlet 4, and the muffler air guide hood 1 is sealed and connected to the bottom plate 2, so that the hot air discharged from the air outlet 4 can be diffused through the ventilation hole. Specifically, the muffler air guide hood 1 is connected with a bracket 5, and the bracket 5 is fixedly connected to the bottom plate 2, so that the muffler air guide hood 1 is relatively fixed to the bottom plate 2. In this embodiment, the exhaust port 3 of the muffler is arranged in the same direction as the air outlet 4, so as to facilitate the assembly and arrangement of the exhaust port 3 of the muffler. In this embodiment, the exhaust port 3 of the muffler is located at the lower part of the generator.

[0016] By adopting this solution, the muffler air guide cover 1 discharges the hot air after cooling the muffler from the bottom, so that when the generator is installed on the frame, the hot air discharged from the air outlet 4 is directed toward the ground, which is beneficial to improving the heat dissipation effect of the generator.

[0017] 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.
