In the case of transmission oil, the fluid torque converter and the planetary gear unit are combined to prevent damage to the transmission and help smooth operation.

These engine oils and transmission oils are recommended to be replaced at regular intervals as the effects of lubrication, rust prevention, cooling and cleaning decrease over time.

As such, the operation of replacing the engine oil and the transmission oil of the automobile is mostly performed by hand, and although some injection devices are used, it is difficult to manage and monitor the injection amount by using a simple nozzle for oil injection.

In particular, there is a problem in that it is difficult to trust whether or not the injection of the engine oil and the transmission oil has been performed since there is no way for the consumer to check whether the existing oil has been discharged and then injected into a new one. Normally, it takes a long time to discharge engine oil and transmission oil, so if the company is unhappy, it saves working time and reduces oil injection amount by replenishing new oil a little while discharging part of the existing oil. Negative gains could easily be taken. On the other hand, the consumer is faced with a complex problem that damages the car because only a portion of the oil has been replaced, along with financial losses, but there is no way to check and contain it.

4 and 5 are before and after the operation of the enlarged portion "A" of Figure 3 for explaining the specific configuration of the handle opening and closing part in the digital oil meter injection gun according to an embodiment of the present invention, Figure 6 7 is an exploded perspective view illustrating a configuration of an injection amount measurement unit in a digital oil meter injection gun according to an embodiment of the present invention, and FIG. 7 illustrates a black box configuration of the injection amount measurement unit in a digital oil meter injection gun according to an embodiment of the present invention. FIG. 8 is a bottom view of the injection amount measuring unit opened in the digital oil meter injection gun according to the embodiment of the present invention, and FIG. 9 is a plan view of the injection amount measurement unit in the digital oil meter injection gun according to the embodiment of the present invention. 10 is a block diagram for calculating and displaying the injection amount of the injection amount measurement unit in the digital oil meter injection gun according to an embodiment of the present invention.

The injection amount measuring unit 120 has an internal chamber CA that communicates with the front end of the handle opening / closing unit 110 to distribute the oil, and detects a flow rate of the oil flowing through the internal chamber CA and injects the amount of oil into the injection chamber. It serves to calculate and display. At this time, not only the oil injection amount can be displayed but also the preservation of the accumulated injection amount can be managed and supervised, and the injection amount can be immediately notified to the consumer to enhance the reliability of the metering injection. It is configured to be switchable for injection.

To this end, the injection amount measuring unit 120 includes a measuring unit casing 121, a pair of gears 123, a controller 124a, a communication interface 124b, a substrate 124, a display 125, and a battery ( 127, and a black box 128.

The measuring unit casing 121 is composed of a casing body 121a, a lower cover 122, and an upper cover 126. The casing body 121a accommodates a gear 123, and an oil inlet 121a and an outlet ( An internal chamber CA communicating with 121b is formed, and a mounting space 121e in which the substrate 124 and the display 125 are integrated, in which the controller 124a and the communication interface 124b are integrated, is formed. In the casing main body 121a, the inner chamber CA and the mounting space 121e are respectively formed at the lower part and the upper part of the casing main body 121a with the horizontal diaphragm interposed therebetween. The cover 122 is fastened to the cover by fastening the bolts 122b and the upper end of the rotation shaft 123a of the gear 123 is installed in a fixed state on the ceiling of the inner chamber CA.

As a result, the bolt 122b may be released from the measurement unit casing 121 to separate the lower cover 122, and then the gear 123 may be easily replaced by a method of separating the gear 123 downward from the rotation shaft 123a. The replacement of the gear 123 is made due to the damage of the gear 123 in use, or for the purpose of replacing the oil-only gear 123 made of different materials with the urea water-only gear 123.

A side of the casing body 121 is also integrally formed with a battery housing 121c for accommodating two batteries 127. In the case of the battery housing 121c, a lower portion of the battery housing 127 is opened to insert and remove the batteries 127. And a housing cap 121d is thus provided. A mounting groove 122a is formed on the upper surface of the lower cover 122 to allow the black box 128 to be stably installed. In the case of the upper cover 126, the display 125 shown in FIG. It is provided with an opening or transparent window so that it can be displayed and allows the calibration and controller control buttons 125c to be located.

The gear 123 is fitted to the rotating shaft 123a fixed to the ceiling of the inner chamber CA to rotate in accordance with the flow of oil circulated in the inner chamber CA. The gear 123 is not a general circular shape, but two pairs of elliptical gears 123 having a long axis and a short axis are engaged to form a pair, and when the flow of oil starts even in a stopped state, the gear 123 is compared with the circular gear 123. Initial rotations are evident even in small oil flows. In addition, magnets 123b are mounted on both ends of the long shaft in the gear 123. As such, the configuration in which the magnets 123b are mounted at both ends of the long shaft serves to maximize the separation between the magnets 123b to rotate the rotor 128c of the black box 128 which will be described later.

 The controller 124a, the communication interface 124b, and the rotation speed sensor 124c are integrated in the substrate 124 and are installed in the adjacent upper mounting space 121e in which the gear 123 is installed. As shown in FIG. 10, the controller 124a is connected to the rotation shaft 123a of the gear 123 to receive the rotation speed data of the gear 123 from the rotation speed sensor 124c for detecting the rotation speed. Calculate the amount of oil injected into Thereafter, as shown in FIG. 9, the control unit is divided into the current oil injection amount 125a and the accumulated oil injection amount 125b so as to be displayed together on the display 125.

In addition, the communication interface 124b may be configured to transmit and notify data of the current oil injection amount calculated by the controller 124a to an external device, and such an external device may include a card terminal and include the current oil injection amount. Make sure to print on this card slip. This enables operators and consumers to immediately identify the correct amount of oil injection, eliminating disbelief about the metering of the oil and building high reliability on both sides.

As shown in the drawing, the display 125 includes a mounting space of the casing body 121 in a state where the controller 124a, the communication interface 124b, and the rotation speed sensor 124c are located on the integrated substrate 124. 121e) is secured and protected so as not to be separated by the upper cover 126. As shown in FIG. 9, the display 125 displays the current oil injection amount 125a and the accumulated oil injection amount 125b as a number. Although not specifically illustrated, the display 125 may be displayed according to whether the calibration and the controller control button 125c are operated. The battery level, calibration progress, and injection unit should be additionally displayed.

The battery 127 is mounted in the battery housing 121c to supply power to all elements that require power to operate in the injection amount measuring unit 120. In this case, the power source includes the controller 124a, the communication interface 124b, the rotation speed sensor 124c, the display 125, and the module chip 128e of the black box 128.

The black box 128 is a flat plate casing 128a having a flat plate shape that is seated in a seating groove 122a formed on an upper surface of the lower cover 122 to form a bottom surface of the inner chamber CA, and the flat plate. The inside of the casing 128a has a length corresponding to the long axis of the gear 123 and is rotatably installed, and a magnet 128d corresponding to the magnet 123b mounted on the gear 123 is mounted at both ends thereof. Rotor 128c which rotates together about the central axis 128ca by the magnetic force at the time of rotation of 123, and is installed in the vicinity of the rotor 128c inside the flat plate casing 128a and the gear 123 It is composed of a module chip (128e) to perform the function of calculating the injection amount of the oil by a method of measuring the rotational speed of the rotor 128c instead of the rotational speed, and continuously storing the data of the calculated oil injection amount. Here, the module chip 128e calculates the number of revolutions of the rotor 128c based on the magnetic sensor sensing the magnetic force of the magnet 128d mounted on the rotor 128c and the data detected by the magnetic sensor. Substituting this at the rotational speed of the gear 123, a process unit for calculating an oil injection amount and a memory for continuously storing the oil injection amount calculated by the process unit are combined.

Note that in the configuration of the black box 128, the oil injection amount is calculated and stored through a path that is completely independent of the controller 124a, so that the controller 124a can be reliable even when external manipulation is involved.

In addition, the flat plate casing (128a) of the black box 128 is made of stainless steel as shown in Figure 7 is sealed so that the inside is not opened without damage, transverse to the center of the flat plate casing (128a) in the circumferential direction A breakable rubber band 128b is provided in the middle so that the flat casing 128a is broken on both sides about the breaking rubber band 128b so as to be opened. As such, when the flat casing 128a is broken around the rubber band 128b, it is impossible to recover the intact form again, so that there is no possibility of anyone operating the black box 128 in the middle.

Here, the broken line 128ba half-sliced along the longitudinal direction is formed in a zigzag form on the inner surface of the breaking rubber band 128b. Through this break line 128ba, it becomes possible to break the flat plate casing 128a more easily. When the flat plate casing 128a is broken in both directions, the module chip 128e formed by the combination of the magnetic sensor, the process unit, and the memory is exposed to the outside about half of the flat plate casing 128a. It can be easily separated from the data analysis task.

The oil passage is closed in the handle opening and closing part 110 so that only the hydraulic pressure less than a predetermined time is closed to block the discharge of oil.

The nozzle unit 130 has an inlet 131a and an outlet 131b and forms a nozzle body 131c to form an inner flow path 131c, and the nozzle body 131 moves forward and backward from the nozzle body 131 inner flow path 131c. A nozzle piston 132 for opening and closing the outlet 131b of the 131, a spring 133 for elastically supporting the nozzle piston 132 to move forward to close the outlet 131b of the nozzle body 131, the nozzle It is installed along the outer circumferential surface of the piston 132 and comprises a U-packing seal 134 for sealing the gap between the nozzle piston 132 and the nozzle body 131.

Here, the nozzle piston 131 has an inner hole 132a formed from a rear end to an intermediate point, and the oil communicates with the inner hole 132a on the wall on the side leaned forward from the point where the U-packing seal 134 is installed. Outflow hole 132b is formed. According to the configuration of the nozzle piston 131, in the state that there is no flow of oil, as shown in FIG. 10, the nozzle piston 131 is blocked by the spring 133 to block the outlet port 131b of the nozzle body 131 However, when the flow of oil is generated by the operation of the trigger 112 of the handle opening and closing portion 110, the oil introduced through the inlet 131b of the nozzle body 131 passes through the inner hole 132a of the nozzle piston 131. It is discharged through the oil outlet hole (132b). At this time, the oil discharged from the oil outlet hole 132b acts on the U-packing seal 134 and pushes the nozzle piston 131 backward, while the outlet port 131b of the nozzle body 131 that is blocked by the tip of the nozzle piston 131. ) Is opened and the oil is finally spilled and oil is injected. In addition to preventing the oil portion from flowing out unnecessarily, the nozzle unit 130 may be disposed within the entire flow path regardless of whether the flow of oil is allowed or blocked in the digital oil meter injection gun according to the embodiment of the present invention. Maintaining a state filled with oil continuously there will be a greater technical meaning in that the injection amount measuring unit 120 plays an important role to precisely measure the oil injection amount.
