Traditional devices only use air cooling to cool it, which cannot cool the contact surface between the wheel and the roller, resulting in low cooling efficiency and easy to cause some unnecessary malfunctions. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Example 1:

[0021] Please refer to the following: Figure 1-3 A car chassis dynamometer with a heat dissipation mechanism includes a dynamometer body 1, a water tank 2 fixedly installed on the rear surface of the dynamometer body 1, a pump 3 fixedly installed on the upper surface of the water tank 2, a water supply pipe 4 fixedly installed on the upper surface of the pump 3, an installation groove 5 opened on the rear surface of the dynamometer body 1, a water collection frame 6 fixedly installed on the inner wall of the installation groove 5, a water delivery slope 8 provided on the upper surface of the dynamometer body 1, a roller 7 movably installed on the inner wall of the water delivery slope 8, a water leakage hole 9 opened on the rear inner wall of the water delivery slope 8, and a spray head 10 fixedly installed on the inner surface of the water collection frame 6.

[0022] Specifically: When using this utility model to test the chassis of a car, the car is first placed on top of the dynamometer body 1, with the wheels positioned between the rollers 7. The controller 17 then activates the dynamometer, causing the rollers 7 to roll and simulate a road surface. The dynamometer body 1 then performs the test. While the rollers 7 are rolling, the pump 3 activates, drawing water from the water tank 2 and delivering it through the water pipe 4 to the water collection frame 6. The water in the collection frame 6 is then sprayed onto the rollers 7 and wheels via nozzles, providing direct water cooling. After cooling, the water falls under its own weight into the return slope, then flows back into the water tank 2 through the drain hole 9 via the water delivery slope 8, thus completing the cooling of the wheels and rollers 7 and the water circulation.

[0023] In this implementation scheme: a controller 17 is fixedly installed on the front surface of the dynamometer body 1, and a water inlet hole 18 is provided on the upper surface of the water tank 2.

[0024] In this implementation scheme: the output end of the water supply pipe 4 is fixedly connected to the rear surface of the water collection frame 6, the water supply slope 8 is set with the front higher than the back, and the interior of the water supply slope 8 is interconnected with the interior of the water tank 2 through the water leakage hole 9.

[0025] Specifically: The design, which is higher in the front and lower in the back, enables the water to flow automatically to the drain hole 9.

[0026] In this implementation scheme: the output end of the servo motor 14 is fixedly connected to the right end of the positive and negative lead screw 12, and the rear surface of the connecting plate 13 is movably connected to the front surface of the dynamometer body 1.

[0027] Specifically: Water is poured into the water tank 2 through the water inlet 18.

[0028] Working principle: This utility model uses a pump 3 to draw water from the water tank 2 and delivers it directly to the water collection frame 6 via a water pipe 4. The water delivered to the water collection frame 6 is then sprayed directly onto the roller 7 and the wheel through a nozzle, thereby directly cooling them with water. Afterward, the water flows through the water delivery slope 8 and the drain hole 9 for direct water recycling. Compared with related technologies, the automotive chassis dynamometer with a heat dissipation mechanism provided by this utility model has the following beneficial effects: This design can achieve the effect of water cooling for the wheel and roller 7, thereby avoiding overheating of the wheel and roller 7, improving cooling efficiency, and avoiding unnecessary economic losses.

[0029] Example 2:

[0030] Please refer to the following: Figure 1-3 A side plate 11 is fixedly installed on the rear surface of the dynamometer body 1. A positive and negative lead screw 12 is movably installed on the adjacent surface of the side plate 11. A connecting plate 13 is movably installed on the outer surface of the positive and negative lead screw 12. A servo motor 14 is fixedly installed on the right side surface of the side plate 11. A movable limit plate 15 is fixedly installed on the rear surface of the connecting plate 13. A fixed limit plate 16 is fixedly installed on the upper surface of the dynamometer body 1.

[0031] Specifically: In the process of using this utility model, when the wheel is located between the rollers 7, the wheel is close to the fixed limiting plate 16, but does not contact the fixed limiting plate 16. Then the servo motor 14 is started, thereby driving the positive and negative lead screws 12 to rotate. The positive and negative lead screws 12 rotate, thereby driving the movable limiting plate 15 to move towards each other until the movable limiting plate 15 moves to the outside of the wheel, but does not contact the wheel, thus completing the movement.

[0032] In this implementation scheme: the output end of the servo motor 14 is fixedly connected to the right end of the positive and negative lead screw 12, and the rear surface of the connecting plate 13 is movably connected to the front surface of the dynamometer body 1.

[0033] Specifically: the servo motor 14 drives the forward and reverse lead screw 12 to rotate.

[0034] In this embodiment: the surface of the water inlet hole 18 is provided with a movable plug, and the controller 17, servo motor 14, and roller 7 are all electrically connected to the dynamometer body 1.

[0035] Working principle: This utility model uses a servo motor 14 to drive the positive and negative lead screws 12 to rotate, thereby driving the movable limiting plate 15 to move, thus limiting the wheel in a certain area. Compared with related technologies, the automobile chassis dynamometer with a heat dissipation mechanism provided by this utility model has the following beneficial effects: This design can achieve the effect of limiting the wheel in a certain area, thereby preventing the automobile wheel from driving off the roller 7 under the action of lateral force during rotation, which would cause a safety accident.

[0036] The controller 17 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0037] The selection of various devices varies depending on the specific circumstances, and should be based on the actual needs and various parameters, taking into account the function and desired effect of the equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
