Description

Technical Field

[0001] The present invention relates to the field of range extenders, and in particular to a range extender with a high-temperature alarm function. Background Art

[0002] A range extender generally refers to an electric vehicle component that can provide additional electrical energy, thereby increasing the mileage of an electric vehicle. In the traditional sense, a range extender refers to a combination of an engine and a generator. The range extender system generally includes an engine, a motor, a controller, and a battery pack. Its working principle is that the generator drives the motor to generate electricity, and the controller regulates or reverses the operation of the motor. In order to ensure the normal use of the range extender and prevent danger during use, a high-temperature alarm needs to be installed inside the range extender as a safety reminder.

[0003] The traditional installation method is to install a temperature probe and alarm inside the range extender. However, since different range extenders contain different devices and generate different amounts of heat, the traditional temperature measurement and alarm method has a large error. This is especially true for high-power devices inside the range extender, such as the engine and controller. The temperatures generated by the two devices during operation are very different, making it difficult for traditional high-temperature alarm devices to provide accurate alarms.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-7 As shown, it includes an external frame 1, and an engine 2, a motor 3, a controller 31 and a battery pack 5 are installed inside the external frame 1. Other devices such as an inverter can also be set inside the external frame 1 as needed to improve the diversity of the range extender. A temperature measuring component is installed inside the external frame 1, and the temperature measuring component is used to detect the temperature inside the external frame 1. An alarm is set outside the external frame 1. The temperature measuring component includes a straight pipe 4, which is installed inside the external frame 1 and is located above the engine 2, the motor 3, the controller 31 and the battery pack 5. A number of rotating components are sleeved on the surface of the straight pipe 4, and an air pipe component is installed on the surface of the rotating component. The air pipe component is connected to the inside of the straight pipe 4, and an air intake head 6 is installed at the end of the air pipe assembly. A temperature probe 7 is installed inside the air intake head 6. An air pump 8 is installed on the surface of the external frame 1, and the air intake end of the air pump 8 is connected to one end of the straight pipe 4.

[0026] When in use, first move the rotating assembly and move the temperature probe 7 to the appropriate position, then rotate the temperature probe to move it to the heat dissipation port of the equipment to be monitored, then start the air pump 8, and the air pump 8 makes the gas 7 flow to itself. At this time, the air intake head 6 will absorb the hot air at the heat dissipation port. At this time, the temperature probe 7 detects that the temperature exceeds a certain threshold, and it can activate the external alarm to alarm, and at the same time can take away the heat, thereby realizing the heat dissipation function.

[0027] The rotating assembly includes an inner sleeve 9, which is stuck on the surface of the straight tube 4 and moves axially. The surface of the inner sleeve 9 is rotatably sleeved with an outer sleeve 10. The surface of the straight tube 4 is provided with a plurality of air inlet holes 11, and the air inlet holes 11 are first arranged in a circular array and then in a linear array on the surface of the straight tube 4. The surface of the inner sleeve 9 is provided with a plurality of ventilation grooves 12. The ventilation grooves 12 are arranged in a circular array on the surface of the inner sleeve 9, and the positions of the ventilation grooves 12 correspond to the positions of the air inlet holes 11. The surface of the outer sleeve 10 is provided with ventilation grooves 2 13. The ventilation grooves 12 and 13 are internally connected, and the trachea assembly is internally connected with the ventilation grooves 2 13, ensuring that the gas inside the trachea assembly can enter the interior of the straight tube 4 through the ventilation grooves 12, 13 and the air inlet holes 11.

[0028] The air pipe assembly includes an outer air pipe 14 and an inner air pipe 15, and a clamping assembly is installed between the outer air pipe 14 and the inner air pipe 15 for fixing the relative positions of the outer air pipe 14 and the inner air pipe 15. The air inlet head 6 is installed at one end of the inner air pipe 15, and a ventilation pipe 16 is installed at one end of the outer air pipe 14. The ventilation pipe 16 is movable through the ventilation groove 12 and the ventilation groove 2 13. The gas enters the interior of the inner air pipe 15 from the air inlet head 6, and then enters the interior of the outer air pipe 14, and finally enters the interior of the ventilation groove 12 through the ventilation pipe 16. At the same time, the length of the inner air pipe 15 inside the outer air pipe 14 can be adjusted to adapt to different equipment interiors.

[0029] A connecting spring 17 is installed on the surface of the outer air pipe 14, and one end of the connecting spring 17 is fixedly installed on the surface of the outer sleeve 10. The vent pipe 16 is movable through the air inlet hole 11. By pulling the outer air pipe 14, the vent pipe 16 can be located outside the vent groove 12 and the vent groove 2 13, which makes it convenient to move the inner sleeve 9. Then, the vent pipe 16 is stuck inside the vent groove 12, the vent groove 2 13 and the air inlet hole 11, so that the inner sleeve 9 and the outer sleeve 10 can be locked to prevent the inner sleeve 9 and the outer sleeve 10 from moving axially on the surface of the straight tube 4 and the inner sleeve 9 and the outer sleeve 10 from rotating and moving.

[0030] A long groove 18 is provided on the surface of the straight tube 4, and a first conductive bar 19 is installed inside the long groove 18. A conductive block 20 is installed inside the inner sleeve 9, and the conductive block 20 is in contact with the first conductive bar 19. A first conductive ring 21 is installed on the surface of the inner sleeve 9, and the first conductive ring 21 is in contact with the conductive block 20. A second conductive ring 22 is installed inside the outer sleeve 10, and the second conductive ring 22 is in contact with the first conductive ring 21. The temperature probe 7 is electrically connected to the second conductive ring 22.

[0031] A second conductive bar 23 is installed inside the outer air pipe 14, and the second conductive bar 23 movably passes through the outer sleeve 10 and is electrically connected to the second conductive bar 23. A third conductive bar 24 is installed on the surface of the inner air pipe 15, and the second conductive bar 23 is electrically connected to the third conductive bar 24. The temperature probe 7 is electrically connected to the third conductive bar 24.

[0032] The clamping assembly includes a plurality of clamping grooves 25 opened on the surface of the inner air pipe 15, and a through groove 26 is opened on the surface of the outer air pipe 14. A clamping block 27 is installed inside the through groove 26, and the clamping block 27 is clamped inside the through groove 26. A compression spring 28 is installed on the surface of the clamping block 27, and one end of the compression spring 28 is installed on the surface of the clamping block 27, and the other end of the compression spring 28 is installed inside the through groove 26. A pull rod is installed on the surface of the clamping block 27, and the pull rod is located inside the through groove 26.

[0033] When in use, the pull rod is used to pull the block 27 away from the inside of the slot 25, so that the block 27 is away from the inside of the slot 25. At this time, the compression spring 28 is in a further compressed state. Then the inner air pipe 15 is moved so that the block 27 is stuck in the inside of another slot 25. At this time, the compression spring 28 can make the block 27 stably stuck in the inside of the slot 25, ensuring the stability of the inner air pipe 15.

[0034] A convex groove 29 is formed inside the outer frame 1 , and a bump 30 is installed on the surface of the straight tube 4 . The bump 30 and the straight tube 4 are stuck in the convex groove 29 .

[0035] It should be noted that the present invention is a range extender with a high temperature alarm function. When in use, by pulling the outer air pipe 14, the vent pipe 16 can be located outside the vent groove 12 and the vent groove 2 13, which makes it convenient to move the inner sleeve 9. Then, the vent pipe 16 is stuck inside the vent groove 12, the vent groove 2 13 and the air inlet 11, and the inner sleeve 9 and the outer sleeve 10 can be locked to prevent the inner sleeve 9 and the outer sleeve 10 from moving axially on the surface of the straight pipe 4. The inner sleeve 9 and the outer sleeve 10 are rotated and moved to move the temperature probe 7 to a suitable position, and then the temperature probe 7 is rotated again. The temperature probe is moved to the heat dissipation port position of the equipment to be monitored, and the air pump 8 is started at this time. The air pump 8 makes the gas 7 flow to itself. At this time, the air inlet head 6 position will suck in the hot air at the heat dissipation port position, and then enter the interior of the external air pipe 14, and finally enter the interior of the ventilation groove 12 through the ventilation pipe 16. The gas can enter the interior of the straight pipe 4 through the ventilation groove 12, the ventilation groove 2 13 and the air inlet hole 11. At this time, the temperature probe 7 detects that the temperature exceeds a certain threshold, and it can activate the external alarm to alarm, and at the same time can take away the heat, thereby realizing the heat dissipation function.
