[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 An electric vehicle seat cushion with active cooling function includes a seat cushion body 1, which is hollow and bottomless. A mounting plate 2 is fixedly and detachably installed inside the seat cushion body 1. A cooling water pad 3 is detachably connected to the side of the mounting plate 2 facing the top of the seat cushion body 1. A fan 4 is fixedly and detachably installed on the side of the mounting plate 2 away from the cooling water pad 3, with the air outlet of the fan 4 facing the cooling water pad 3. This allows the seat cushion body 1 to be rapidly cooled by the cooling water pad 3 and the fan 4, thereby reducing the probability of the user being burned by the seat cushion body 1.

[0023] The mounting plate 2 is connected to the inner wall of the seat cushion body 1 by bolts or other fasteners. The cooling water pad 3 is attached to the mounting plate 2 by adhesive or by elastic straps, etc. The side of the cooling water pad 3 away from the mounting plate 2 is in contact with the inner wall of the seat cushion body 1 so that the cooling water pad 3 can absorb the heat on the seat cushion body 1, thereby cooling the seat cushion body 1.

[0024] Furthermore, there are two fans 4, which are respectively located on the bottom of the mounting plate 2, facing the front and rear sides of the top wall of the seat body 1. That is, the air outlet sides of the two fans 4 correspond to the front and rear seats of the seat, respectively, so that the front and rear seats of the electric vehicle can be cooled quickly, making it convenient for the rider to carry passengers.

[0025] In order for the air blown by the fan 4 to come into contact with the cooling water pad 3 and the seat cushion body 1, in this application, the mounting plate 2 is provided with a plurality of ventilation openings 203, which are arranged along the length of the seat cushion body 1, and the air outlet side of the fan 4 faces the ventilation openings 203. This allows the air blown by the fan 4 to circulate on both the upper and lower sides of the mounting plate 2, thereby accelerating the airflow and quickly cooling the seat cushion body 1 and the cooling water pad 3.

[0026] It should be noted that two support plates 201 are fixedly provided on the side of the mounting plate 2 facing the fan 4, and the two fans 4 are located between the two support plates 201. Two sliding rods 202 are fixedly provided between the two support plates 201 along the length of the seat body 1. The two sliding rods 202 are symmetrically distributed on the left and right sides of the fan 4, and both fans 4 can be detachably connected to the two sliding rods 202.

[0027] Two support plates 201 protrude from the support plates 201 along the thickness direction of the seat cushion body 1, and fans 4 are distributed along the length direction of the seat cushion body 1. The two ends of the fans 4 are respectively fixedly connected to the opposing surfaces of the two support plates 201 to support the fans 4. In this embodiment, the fans 4 are located between the two support plates 201 and also between the two sliding rods 202.

[0028] Specifically, the fan 4 is provided with symmetrical connecting parts 5 on the left and right sides. The end of the connecting part 5 away from the fan 4 is fixedly provided with a sliding sleeve 501, and the sliding sleeve 501 is slidably sleeved on the sliding rod 202 so that the sliding sleeve 501 can slide on the sliding rod 202 to drive the fan 4 to move and change position.

[0029] The connector 5 consists of a connecting plate and a connecting rod. The connecting plate is fixedly connected to the side of the fan 4 facing the slide rod 202, and the connecting rod is fixedly connected to the side of the connecting plate facing the slide rod 202. The top projection of the connector 5 is T-shaped. The sliding sleeve 501 is fixedly connected to the end of the connecting rod away from the connecting plate, and the sliding sleeve 501 is slidably fitted onto the slide rod 202. Therefore, the sliding sleeve 501 can slide along the length of the slide rod 202, allowing the fan 4 to slide along the length of the seat body 1. This changes the position of the two fans 4, allowing the fan 4 located on the rear seat to move to the area of ​​the front seat, so that both fans 4 can simultaneously cool the front seat of the seat body 1, which is suitable for situations where single-person riding requires rapid cooling of the front seat.

[0030] On the other hand, a threaded hole is provided on the sliding sleeve 501, and a locking groove is provided on the sliding rod 202. A fixing bolt is threaded into the threaded hole of the sliding sleeve 501. By rotating the fixing bolt, the bottom end of the fixing bolt enters or disengages from the locking groove, thereby causing the fixing bolt and the sliding rod 202 to abut or move away from each other, so that the sliding sleeve 501 can be fixed on the sliding rod 202 or slide on the sliding rod 202, preventing the fan 4 from moving its position during operation.

[0031] In this embodiment, a power supply 6 and a speed controller 7 (DC PWM speed controller) are fixedly mounted on the side of the mounting plate 2 facing the fan 4. The output terminal of the power supply 6 is electrically connected to the input terminal of the speed controller 7, and the output terminal of the speed controller 7 is electrically connected to the input terminal of the fan 4. The power supply 6 supplies power to the speed controller 7 and the fan 4. The speed controller 7 receives signals and controls the operating state of the fan 4. When a manual start signal is received, the speed controller 7 supplies power to the fan 4 through its output terminal to start it; when a speed control signal is received, the speed controller 7 adjusts the current output at its output terminal to regulate the speed of the fan 4.

[0032] The working principle and usage process of this utility model are as follows: First, when the temperature of the seat body 1 is high and the electric vehicle needs to carry two people, the two fans 4 correspond to the front and rear seats of the seat body 1 respectively. At this time, the fans 4 are turned on to blow air onto the seat body 1 and the cooling water pad 3, so that both the seat body 1 and the cooling water pad 3 can be cooled down quickly. At the same time, the cooling water pad 3 absorbs the heat on the seat body 1, so that the user will not be burned when sitting on the seat body 1, and the riding will be more comfortable.

[0033] When the electric vehicle only needs to carry one person, the fan 4 of the rear seat of the corresponding seat body 1 is moved to the area of ​​the front seat of the corresponding seat body 1, so that both fans 4 blow air on the front seat of the seat body 1, which speeds up the temperature drop of the front seat of the seat body 1 and improves the user experience of a single rider.
