Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1 and 2, an embodiment of the present invention provides a geometric measuring tool 1000 for a water nozzle, where the geometric measuring tool 1000 for a water nozzle is applied to detecting an angle of a water nozzle of a vehicle-mounted power supply 2000. The vehicle-mounted power supply 2000 may be a vehicle-mounted charger, a vehicle-mounted heat exchanger, or other industrial products requiring heat exchange. The vehicle-mounted power supply 2000 radiates heat through fluid media input and output by the water nozzle, and when the vehicle-mounted power supply is mounted on an object such as an automobile, the water nozzle angle of the vehicle-mounted power supply 2000 needs to be within a proper range because the space of a platform is limited and interference with other structures is easily generated.

In one embodiment, please refer to fig. 1 and fig. 2, which take a vehicle-mounted power supply 2000 on a vehicle-mounted charger as an example. The first water nozzle 251 and the second water nozzle 252 are arranged on a water nozzle seat 254 on the outer surface of the vehicle-mounted power supply 2000 and are used for inputting and outputting a cooling medium, wherein the cooling medium can be water or other cooling liquid. The shapes of the first nozzle 251 and the second nozzle 252 may be the same or different, depending on the actual industrial situation.

The water nozzle geometric measurement jig 1000 comprises a base plate 30, wherein a first hole 10 and a second hole 20 of a non-circular through hole are formed in the base plate 30, and the extending direction of the length of the first hole 10 is a straight line. In one embodiment, the first and second holes 10 and 20 have the same shape and are disposed on the base plate 30 in an axisymmetric or centrosymmetric manner. The first and second holes 10 and 20 of the base plate 30 receive the first and second water nozzles 251 and 252, respectively. In other embodiments, the shapes of the first hole 10 and the second hole 20 may be different, depending on the shapes of the first nozzle 251 and the second nozzle 252. The water nozzle geometry measuring jig 1000 provided in this embodiment is described by taking the example that the shapes of the first water nozzle 251 and the second water nozzle 252 are the same, and reference can be made when the shapes of the first water nozzle 251 and the second water nozzle 252 are different.

In one embodiment, referring to fig. 2 and 9, the first nozzle 251 is in an "L" shape, and the first nozzle 251 includes a first nozzle 2500 and a second nozzle 2510. The first nozzle 2500 is connected to the nozzle seat 254, so as to fix the first nozzle 251 to the vehicle-mounted power supply 2000, and the second nozzle 2510 is a measurement object of the nozzle geometry measuring jig 1000 provided in this embodiment. The second nozzle 2510 includes a liquid outlet 2511 and a liquid inlet 2512, and the liquid in the first nozzle 251 flows from the liquid inlet 2512 to the liquid outlet 2511. The liquid outlet end 2511 includes a first protrusion 2521, the liquid inlet end 2512 includes a second protrusion 2522, and the first protrusion 2521 and the second protrusion 2522 are respectively located on the outer peripheral walls of the liquid outlet end 2511 and the liquid inlet end 2512.

When the space in which the vehicle-mounted power supply 2000 is located is narrow and small, interference with other structures is easier to occur, the spacing distance can be preset to a small value so as to ensure that interference occurs when the angle of the water nozzle does not affect assembly, and otherwise, when the space in which the vehicle-mounted power supply 2000 is located is sufficient, the spacing distance can take a large value. In addition, when the first nozzle 251 and the second nozzle 252 are installed in different environments, the distance between the first hole 10 and the second hole 20 in the width direction may be different, and if the installation condition of the first nozzle 251 is more severe than that of the second nozzle 252, the distance d1 between the first hole 10 in the width direction may be smaller than the distance d2 between the second hole 20 in the width direction.

8. The water nozzle geometric measurement jig of a vehicle power supply of claim 7, further comprising a flange bearing, wherein the flange bearing is disposed on the base plate, and the detection rod is connected to the flange bearing.

9. The water nozzle geometric measurement jig of the vehicle-mounted power supply as claimed in claim 8, wherein the detection lever comprises a first lever portion and a second lever portion, the indication plate is disposed on the first lever portion, the first lever portion is slidably connected with the flange bearing, the second lever portion is a threaded rod and is used for being in threaded fit with the mounting hole of the vehicle-mounted power supply, and when measurement is performed, the second lever portion moves to the bottom of the mounting hole so that the depth of the mounting hole can be obtained through a reading on the scale indicated by the indication plate.

10. The water nozzle geometric measurement jig of the vehicle-mounted power supply as claimed in claim 1, further comprising a support pillar and a limiting block, wherein the support pillar is disposed on a first surface of the water nozzle geometric measurement jig facing the vehicle-mounted power supply, the support pillar is used for supporting and balancing the water nozzle geometric measurement jig, and the limiting block is disposed on the first surface and is used for limiting the water nozzle geometric measurement jig from moving relative to the vehicle-mounted power supply.
