[0054] The cooling system equipment for automobile engine bench test is a very important test equipment in the test development and verification process. It is necessary to control the temperature of the engine under different working conditions in order to test various performance indicators of the engine. Before the test run, the cooling system test equipment needs to be filled with coolant, and a coolant filling device is required. When the coolant filling device for engine test fixtures in the prior art is used, it can fill coolant for engine benches at the same height. When the height of the engine bench is different, it cannot meet its filling needs, and its use is relatively limited.

[0055] In order to solve the above problems, the utility model provides a coolant filling device for an engine test fixture. Since the coolant filling device for an engine test fixture is provided with a lifting component, when in use, for engine test fixtures of different specifications, when their heights are different, especially when the coolant filling ports of the engine test benches are at different heights, the height of the filling head can be adjusted by operating the lifting component so that it can be aligned with the coolant filling ports of the engine test benches at different heights. The coolant filling device can be suitable for engine test fixtures of different specifications and has fewer limitations on use.

[0056] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] The embodiment of the utility model provides a coolant filling device for an engine test fixture, such as Figure 1 As shown, the coolant filling device for the engine test fixture includes a test bench 100 , a coolant storage tank 200 , a filling assembly 300 and a lifting assembly 400 .

[0058] Specifically, the coolant storage tank 200 is used to store coolant and is installed on the stand 100; the filling assembly 300 is arranged on the stand 100, one end of which is connected to the inside of the coolant storage tank 200 and the other end of which is provided with a filling head 330; the lifting assembly 400 is fixedly arranged on one side of the filling assembly 300, and the output end of the lifting assembly 400 is transmission-connected with the filling head 330 to link the filling head 330 of the filling assembly 300 to move in the vertical direction.

[0059] Furthermore, the filling assembly 300 includes a connecting pipe connecting the filling head 330 and the coolant storage tank 200, one end of the connecting pipe is connected to the discharge port of the coolant storage tank 200, and the other end is connected to and communicated with the liquid inlet end of the filling head 330; and a deformable portion 312 is formed in the connecting pipe at a portion located between the lifting assembly 400 and the coolant storage tank 200.

[0060] When in use, for engine test fixtures of different specifications, when their heights are different, especially when the coolant filling ports of the engine rig 100 are at different heights, the height of the filling head 330 can be adjusted by operating the lifting assembly 400 so that it can be aligned with the coolant filling ports of the engine rig 100 at different heights. This makes it suitable for engine test fixtures of different specifications, has fewer usage limitations, and is more practical.

[0061] In addition, by forming a deformable portion 312 in the connecting pipeline between the lifting assembly 400 and the coolant storage tank 200, when the height of the filling head 330 is adjusted, the deformable portion 312 can be deformed along with the movement of the filling head 330, thereby avoiding the problem of pulling the connecting pipeline and causing damage when the filling head 330 moves, which is beneficial to the reliability of the coolant filling device for the engine test fixture.

[0062] Therefore, the coolant filling device for the engine test fixture provided by the embodiment of the utility model has the advantages of less limitation and greater practicality on the basis of ensuring working reliability.

[0063] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, if Figure 1-Figure 3 As shown, the connecting pipeline includes a first connecting pipe 310 and a second connecting pipe 320, one end of the first connecting pipe 310 is connected and communicated with one end of the second connecting pipe 320, the other end of the first connecting pipe 310 is connected and communicated with the discharge port of the coolant storage tank 200, the other end of the second connecting pipe 320 is connected and communicated with the liquid inlet end of the filling head 330, and the output end of the lifting assembly 400 is transmission-connected with the side wall of the second connecting pipe 320; at least a portion of the first connecting pipe 310 is configured as a flexible hose to constitute a deformation portion 312.

[0064] Specifically, by setting the connecting pipeline as the first connecting pipe 310 and the second connecting pipe 320, at least a part of the first connecting pipe 310 is set as a flexible hose to form the deformation part 312, which is more conducive to the arrangement of the connecting pipeline. In addition, the output end of the lifting component 400 is transmission-connected with the side wall of the second connecting pipe 320. Since the filling head 330 is set at the end of the second connecting pipe 320, such a structure is more conducive to the position adjustment of the filling head 330, especially to avoid the problem that the lifting component 400 is too far away from the filling head 330, which causes laborious operation or the transmission distance is too long to affect the reliability of use.

[0065] Those skilled in the art should understand that at least a portion of the first connecting tube 310 is set as a flexible hose to constitute the deformation portion 312, which can be understood as setting the entire first connecting tube 310 as a flexible hose, or setting a portion in the middle of the first connecting tube 310 as a flexible hose, for example, one third is set as a flexible hose, and the other portion is set as a steel pipe.

[0066] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, if Figure 1 As shown, the second connecting pipe 320 is set as a rigid structure, and the second connecting pipe 320 extends in the vertical direction. The lifting assembly 400 is fixedly connected to the outer wall of the coolant storage tank 200 near the filling head 330, and the output end of the lifting assembly 400 is fixedly connected to the outer peripheral wall of the second connecting pipe 320, and can drive the second connecting pipe 320 to move in the vertical direction to link the filling head 330 to move in the vertical direction.

[0067] Specifically, by setting the second connecting pipe 320 as a rigid structure, it is possible to prevent the second connecting pipe 320 from being deviated when being driven and affecting the height adjustment of the filling head 330. In addition, the lifting assembly 400 is fixedly connected to the outer wall of the coolant storage tank 200 near the filling head 330, so that the installation of the lifting assembly 400 can be achieved without modifying other structures of the engine test tooling, which is more cost-effective.

[0068] It should be understood that the second connecting pipe 320 can be a connecting pipe with various rigid structures such as a steel pipe, an iron pipe, etc.

[0069] The present invention does not make any specific requirements for this, and it can be set according to actual design and usage requirements.

[0070] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, the filling head 330 is provided with a flow meter 340 , and the first connecting pipe 310 is provided with a pressure pump 350 .

[0071] Specifically, by setting the flow meter 340, the coolant flow of the filling head 330 can be monitored in real time, which is helpful for the user to obtain the filling status. By setting the pressure pump 350, the coolant can be pressurized, and the coolant can be filled even when the filling head 330 is in a higher position.

[0072] The specific forms of the flow meter 340 and the pressure pump 350 are not limited. For example, the flow meter 340 can be various flow meters 340 such as an electronic flow meter 340 and a pointer flow meter 340; the pressure pump 350 can be various pressure pumps 350 such as a vane pump and a gear pump.

[0073] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, if Figure 1 and Figure 3 As shown, the lifting assembly 400 includes a screw slider component 360.

[0074] Specifically, in the present embodiment, the screw rod 361 in the screw rod slider component 360 is fixedly arranged in the vertical direction on the outer wall of the coolant storage tank 200 near the filling head 330, one end of the slider 362 of the screw rod slider component 360 is sleeved on the screw rod 361, and the other end is fixedly connected to the second connecting tube 320. The rotation of the screw rod 361 drives the slider 362 to link the filling head 330 to move in the vertical direction.

[0075] More specifically, in this embodiment, since the screw slider component 360 has the advantage of high transmission accuracy, this embodiment sets the lifting assembly 400 as the screw slider component 360, and uses the screw slider component 360 to adjust the height of the filling head 330, which is beneficial to the adjustment accuracy of the filling head 330.

[0076] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, if Figure 1 and Figure 3 As shown, a rotating connection portion 363 is provided on the outer side wall of the coolant storage tank 200 close to the filling head 330 , and the screw rod 361 is rotatably connected to the rotating connection portion 363 .

[0077] Furthermore, in the coolant filling device for the engine test tooling provided in the embodiment of the utility model, the rotating connection part 363 is configured as: a support frame formed on the outer wall of the coolant storage tank 200 close to the filling head 330 and extending in the vertical direction; and an adjusting hand wheel 364 is also provided at the end of the screw rod 361.

[0078] By setting the rotating connecting part 363 as a support frame, it is possible to avoid additional modification of the coolant storage box 200, that is, to achieve the installation of the screw rod 361, which has the advantage of low cost. In addition, by setting the adjusting hand wheel 364, it is more labor-saving to drive the screw rod 361 to rotate.

[0079] In other alternative embodiments, the lifting assembly 400 may also include a hydraulic lifting component.

[0080] Specifically, the hydraulic lifting component includes a hydraulic lifting cylinder and a control unit which are arranged on the platform 100 and close to one side of the filling head 330 , and the hydraulic lifting cylinder extends in the vertical direction, and its output end is fixedly connected to the outer wall of the second connecting pipe 320 .

[0081] The hydraulic lift cylinder can be set as an electronic hydraulic lift cylinder (not shown in the diagram of this scheme), and the control unit can be set as a controller, which is electrically connected to the electronic hydraulic lift cylinder. The user controls the working state of the electronic hydraulic lift cylinder through the controller. For example, when the electronic hydraulic lift cylinder piston is controlled to extend, the filling head can be linked to rise; conversely, when the electronic hydraulic lift cylinder piston is controlled to retract, the filling head can be linked to lower.

[0082] It should be understood that the control unit can also be configured as a control switch or other control element, which is not the only requirement in this embodiment.

[0083] It should be further understood that the present embodiment only shows a partial structure of the lifting assembly 400, and it may also be configured as other lifting assemblies, such as an electric telescopic rod, etc.

[0084] Furthermore, in the coolant filling device for the engine test fixture provided in the embodiment of the utility model, if Figure 1 As shown, at least three rollers 110 are also provided at the bottom of the stand 100, and the at least three rollers 110 are evenly and spacedly distributed along the circumference of the stand 100. Each of the at least three rollers 110 is fixedly connected to the bottom surface of the stand 100 through a shock absorbing component 120.

[0085] Specifically, by providing the roller 110, the coolant filling device for the engine test fixture can be made more convenient to move; in addition, by providing the shock-absorbing component 120 between the roller 110 and the test bench 100, the shock-absorbing component 120 can effectively reduce the vibration transmitted from the roller 110 to the test bench 100, so that the coolant in the coolant storage tank 200 can be kept stable, and the coolant in the coolant storage tank 200 can be prevented from vibrating when the coolant is vibrated, which makes it convenient for the staff to push the filling device to move, and avoids the vibration of the coolant in the coolant storage tank 200 from hindering the movement of the filling device.

[0086] More specifically, in this embodiment, the number of rollers 110 is not limited, for example, it can be set to 3, and when it is set to 3, it can be set to 1 at the front end of the rack 100 and 2 at the rear end. It can also be set to 4, and when it is set to 4, it can be set to 2 at the front end of the rack 100 and 2 at the rear end. Of course, it can also be set to 5, 6, etc. This embodiment does not make a sole requirement for this.

[0087] The structure of the roller 110 is not limited. In one embodiment, the roller 110 can be set as a universal wheel. The universal wheel allows the roller 110 to rotate in any direction when the coolant filling device for the engine test fixture is moved. Even when the coolant filling device for the engine test fixture is offset at a small angle, the roller 110 will not get stuck. This structure has the advantage of good controllability.

[0088] The structure of the shock absorbing component 120 is not limited, and it can be configured as various shock absorbers such as a hydraulic shock absorber, a spring shock absorber, etc.

[0089] In one embodiment, if Figure 1 and Figure 2 As shown, the shock absorbing component 120 is configured as a spring shock absorber, and each shock absorbing component 120 includes an elastic component arranged between a corresponding roller 110 and the bottom surface of the stand 100, and at least one guide rod 122 arranged on the periphery of the elastic component and extending through the stand 100 in the vertical direction; each roller 110 is fixedly connected to the bottom surface of the stand 100 through a connecting piece, the elastic component is a damping spring 121 sleeved on the end of the roller 110, and one end of each guide rod 122 is fixed to the connecting piece, and the other end passes through the stand 100 and extends out of the top surface of the stand 100.

[0090] With such a structure, the vibration received by the roller 110 is damped by the damping spring 121, and the longitudinal movement of the roller 110 is guided by the provided guide rod 122 and the guide groove 123. With such a structure, the stability of the coolant filling device for the engine test fixture during movement can be ensured while achieving shock absorption.

[0091] It should be understood that each shock absorbing component 120 may be provided with one guide rod 122 or may be provided with two or more guide rods 122 , and this embodiment does not impose a unique requirement on the specific number.

[0092] The following describes the use principle of the coolant filling device for the engine test fixture by taking the example that the damping component 120 is set as a spring damper and the adjusting component is set as a screw slider component 360:

[0093] When the engine test fixture needs to be filled with coolant, Figure 1-Figure 3As shown, the test bench 100 drives the filling device to move through the roller 110, so that the filling head 3309 is aligned with the coolant filling port of the engine test bench 100, and the coolant in the coolant storage tank is extracted by the pressure pump 350, and injected into the coolant tank of the engine test fixture through the filling head 330. When the coolant filling port of the engine test fixture is at different heights, the height of the filling head 330 can be adjusted by setting the lifting component 400, so that the filling head 330 can be aligned with the coolant filling ports of the engine test fixtures at different heights, and the use limitation is smaller.

[0094] Specifically, when the filling device is moved by the roller 110, the vibration received by the roller 110 is damped by the damping spring 121, and the longitudinal movement of the roller 110 is guided by the provided guide rod 122 and the guide groove 123. Through the damping structure, the vibration transmitted to the stand 100 by the roller 110 can be effectively reduced, and the coolant in the coolant storage tank 200 can be kept stable, and the coolant in the coolant tank can be prevented from vibrating when vibrated, so that it is convenient for the staff to push the filling device to move, and the coolant vibration in the coolant storage tank 200 can be prevented from hindering the movement of the filling device. When it is necessary to adjust the height of the filling head 330, the adjusting hand wheel 364 is turned, and the adjusting hand wheel 364 drives the screw rod 361 to rotate. The screw rod 361 drives the filling head 330 to rise and fall through the threaded connection formed with the slider 362, and the slider 362 drives the second connecting pipe 320 to rise and fall, and then drives the filling head 330 to rise and fall.
