Description

Technical Field

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

[0002] As a product that combines the functions of "house" and "car", RV can integrate "clothing, food, housing and transportation" into one, realizing the function of "traveling in life and living in travel". As the power source of RV, RV engine is the heart of RV, affecting the power, economy and environmental protection of RV.

[0003] When the RV engine is running, a lot of heat will be generated. If the heat cannot be dissipated, it will cause the engine to burn out. Chinese patent document CN110671202B discloses an RV engine protection device, including an engine, a mounting plate is fixedly installed at the bottom of the engine, a bottom plate is movably installed at the bottom of the mounting plate, a mounting block is fixedly installed in the middle of the lower end of the mounting plate, and a mounting groove is opened in the middle of the upper end of the bottom plate. The RV engine protection device is convenient for absorbing the heat generated by the engine, dissipating the heat, cooling the engine, avoiding engine overheating and damage, improving the protection effect, and can be adjusted to improve the flexibility of the RV engine protection device, which is convenient to use.

[0004] In this prior art, the heat generated by the engine is absorbed and dissipated by heat sinks arranged on the side panels. However, various control devices will also generate heat during the use of the engine. Moreover, since the control devices of the engine are installed at different positions, heat will be generated at different positions during the use of the engine. Therefore, the heat dissipation effect of the control devices distributed in various places in this prior art is not ideal. Once the control devices are overheated, it is easy to affect the use or even cause damage, thereby affecting the use of the generator. Utility Model Content

[0005] In order to solve the technical problem of poor heat dissipation effect of control devices in the prior art, the utility model provides a generator, including a mounting base, on which a power device is mounted, the power device is provided with a pull plate, an air inlet of the pull plate for introducing cooling air into the power device, and an exhaust port for discharging hot air heated by the power device; wherein a mounting bracket is provided on the mounting base, the mounting bracket is located outside the pull plate, and the control device is mounted on the mounting bracket.

[0006] Compared with the prior art, in this solution, the control components are centrally installed on the mounting bracket, and the mounting bracket is located on the outside of the pull plate. Therefore, the cooling air introduced into the air inlet of the pull plate will pass through the mounting bracket, thereby centrally dissipating the heat of the control components on the mounting bracket, which can ensure the centralized heat dissipation effect of the control components and avoid problems such as overheating and damage of the control components.

[0007] Moreover, after the control components are centrally installed on the mounting bracket, it is also convenient to centrally inspect and maintain the control components. Reasonable installation of the control components on the mounting bracket can also reduce the installation space requirement of the control components, thereby reducing the size of the generator, making the generator miniaturized and more lightweight.

[0008] Preferably, the mounting bracket has a first mounting surface and a second mounting surface that intersect each other. This solution can make the installation of the control device more reasonable, avoiding the problems of excessive concentration of control devices causing mutual interference and excessive heat concentration.

[0009] Preferably, an inverter unit is mounted on the mounting bracket, and a vent is provided on the mounting bracket, and the vent is directly facing the inverter unit. This solution can enhance the heat dissipation effect of the inverter unit and also ensure the cooling effect of the power device.

[0010] Preferably, a heat dissipation component is provided on the surface of the inverter unit. This solution can enhance the heat dissipation effect of the inverter unit.

[0011] Preferably, the heat dissipation component is arranged on a side of the inverter unit facing the mounting bracket. This solution can enhance the heat dissipation effect of the inverter unit.

[0012] Preferably, the heat dissipation component is a heat dissipation rib group. This solution can increase the surface area of ​​the inverter unit, thereby enhancing the heat dissipation effect of the inverter unit.

[0013] Preferably, the heat dissipation rib group is arranged vertically along the inverter unit. This solution can enhance the heat dissipation effect of the inverter unit, and the vertically arranged heat dissipation rib group can guide the airflow, thereby preventing the hot airflow from flowing to other components nearby after heat dissipation, and avoiding the influence of high temperature air on other components.

[0014] The utility model has the following beneficial effects:

[0015] 1. Centrally install the control components on the mounting bracket to ensure the centralized heat dissipation effect of the control components and avoid problems such as overheating and damage of the control components;

[0016] 2. It is convenient to carry out centralized inspection and maintenance of the control components. Reasonable installation of the control components on the mounting bracket can also reduce the installation space requirements of the control components, thereby reducing the size of the generator, making the generator smaller and more lightweight.

[0020] The following is further described in detail through specific implementation methods:

[0021] 1. Definition

[0022] Control devices: including inverters, sensors, frequency converters and other devices.

[0023] Inverter unit: refers to the inverter, a device that converts direct current into alternating current. Its working principle is based on the switching characteristics of semiconductor devices. It controls the power supply voltage and current through rapid switching, thereby converting direct current into alternating current of corresponding frequency and voltage.

[0024] Heat dissipation ribs: A structure designed in electronic equipment to increase the heat dissipation area and improve heat dissipation efficiency.

[0025] 2. The reference numerals in the drawings of the specification include: mounting base 1, mounting bracket 2, inverter unit 3, vent 4, heat dissipation component 5, pull plate 6, mounting portion 7.

[0026] The embodiment is basically as shown in the attached Figure 1-Figure 3 As shown: a generator includes a mounting base 1, on which a power device is mounted. The power device is provided with a pull plate 6, an air inlet of the pull plate 6 for introducing cooling air into the power device, and an exhaust port for discharging hot air heated by the power device.

[0027] The mounting base 1 is provided with a mounting bracket 2, which is located outside the pull plate 6, and a control device is installed on the mounting bracket 2. The bottom of the mounting base 1 is provided with a mounting portion 7, which is detachable from the mounting bracket 2 by bolts.

[0028] The mounting bracket 2 has a first mounting surface and a second mounting surface intersecting each other, an inverter unit 3 is arranged on the first mounting surface, and a vent 4 is arranged on the mounting bracket 2, and the vent 4 partially faces the inverter unit 3. A heat dissipation component 5 is arranged on one side of the surface of the inverter unit 3 facing the mounting bracket 2. In this embodiment, the heat dissipation component 5 is a heat dissipation rib group, and the heat dissipation rib group is vertically arranged along the inverter unit 3. In other embodiments, the heat dissipation component 5 may also adopt other structures.

[0029] The specific implementation process is as follows: when in use, the power device is started by using the pull plate 6, and the cooling air flows to the air inlet of the pull plate 6. During the flow process, it will first pass through the vents 4 on the mounting base 1, and then flow to the air inlet of the pull plate 6. When the cooling air passes through the vents 4, it takes away the heat emitted by the control device installed on the mounting bracket 2, and finally is discharged through the exhaust port, thereby taking away the heat inside the control device and the generator, avoiding the control device and the generator from being overheated, and ensuring the normal use of the control device and the generator.
