Description

Technical Field

[0001] This invention relates to the field of vehicle fuel consumption detection technology, and in particular to a fuel consumption analyzer and its usage method. Background Technology

[0002] Fuel consumption is one of the important indicators for drivers to understand the vehicle they are driving. It not only allows drivers to make timely judgments about vehicle malfunctions, but also helps to promote drivers to improve their driving habits. Fuel consumption is usually detected using a fuel consumption analyzer installed on the vehicle.

[0003] To improve the accuracy of fuel consumption detection, an on-board fuel consumption meter, as disclosed in the invention patent with patent publication number CN114812717A, is usually used. It is installed in the fuel line between the car's fuel tank and the engine. Currently, common on-board fuel consumption meters usually use a quick-connect fuel line connector, as disclosed in the utility model with patent publication number CN217813718U, to achieve a quick connection between the fuel line and the on-board fuel consumption meter.

[0004] As can be seen in the attached drawings of the above-mentioned utility model, in order to achieve a quick connection between the connector and the oil pipeline, the outer side of the connector is set in a gourd shape. However, the oil pipeline is often relatively flexible, and the difference between the inner diameter of the oil pipeline and the outer diameter of the connector is relatively large. Before installation, it is necessary to expand the port of the oil pipeline by means of heating or tool expansion, which reduces the connection efficiency between the oil pipeline and the connector. Summary of the Invention

[0005] In view of this, the present invention proposes a fuel consumption analyzer and its usage method, which can realize the rapid connection between the fuel consumption analyzer and the oil pipeline, thereby improving the installation efficiency of the fuel consumption analyzer.

[0006] The technical solution of this invention is implemented as follows: On one hand, this invention provides a fuel consumption analyzer, comprising a body and two connecting pipes, the two connecting pipes being disposed on the body, each connecting pipe comprising a main pipe, a support pipe, and a flexible connecting pipe, wherein...

[0007] The main tube is fixedly mounted on the body, and the two main tubes are connected through the body.

[0008] The support tube is fixedly installed at the end of the main tube away from the machine body;

[0009] The middle position of the flexible connector is rotatably connected to the middle position of the support tube. The cross-sections of both the flexible connector and the support tube are arc-shaped, and there is an movable gap between them. The side of the support tube away from the center line of the main tube is flush with the main tube, and the side of the flexible connector away from the center line of the main tube is selectively flush with the main tube.

[0010] Based on the above technical solutions, preferably, the connecting pipe further includes a limiting rod, and a sliding groove is provided on the outer side of the main pipe. The limiting rod is slidably disposed in the sliding groove and selectively blocks the moving gap.

[0011] More preferably, the end of the limiting rod away from the machine body is stepped, which is used to limit the rotation range of the live pipe.

[0012] More preferably, the connecting pipe further includes a fixing sleeve, which is fitted over the outside of the main pipe and fixedly connected to the limiting rod. A gap is provided between the fixing sleeve and the main pipe for fixing the oil pipeline connected to the connecting pipe.

[0013] More preferably, a slot is provided at the end of the fixing sleeve away from the machine body, and a locking nut is connected to the outer side of the fixing sleeve by a threaded connection.

[0014] More preferably, the outer side of the main tube is connected to a drive nut via a threaded connection, and the drive nut selectively abuts against the fixing sleeve.

[0015] More preferably, the connecting pipe further includes a sealing cylinder, which is slidably disposed within the main pipe and fixedly connected to the limiting rod. The sealing cylinder can slide between the support pipe and the movable connecting pipe to seal the movable gap.

[0016] Based on the above technical solutions, preferably, a plurality of fixing plates are fixedly provided on the body for fixing the body to the vehicle body;

[0017] A reinforcement hole is provided on the side of the machine body close to the vehicle body. A support plate and a spring are slidably disposed in the reinforcement hole. The spring is located on the side of the support plate away from the vehicle body and supports it.

[0018] More preferably, an airbag is fixedly installed on the side of the abutment plate away from the vehicle body. The airbag is located inside the spring and selectively abuts against the body. The airbag is made of elastic material. When the abutment plate abuts against the vehicle body, the airbag deforms.

[0019] Secondly, the present invention provides a method for using the above-mentioned fuel consumption analyzer, characterized by comprising the following steps:

[0020] S1, unscrew the locking nut from the fixing sleeve and put it on the oil pipeline, turn the driving nut toward the side closer to the machine body, and slide the limiting rod toward the side closer to the machine body to disengage the limiting rod from the movable gap;

[0021] S2, rotate the side of the live connector away from the machine body toward the side closer to the support pipe, and fit the end of the oil pipeline onto the outside of the support pipe and the end of the live connector away from the machine body;

[0022] S3, repeatedly press the end of the live connector near the machine body and rotate the oil pipeline simultaneously, using the separation of the live connector from the support pipe to expand the port of the oil pipeline;

[0023] S4, slide the oil pipeline towards the side closer to the machine body. When the end of the oil pipeline moves to the outside of the main pipe, turn the drive nut away from the machine body to push the fixed sleeve to slide, so that the end of the oil pipeline is located between the main pipe and the fixed sleeve.

[0024] S5, tighten the locking nut on the oil pipeline to the outside of the fixing sleeve to fix the oil pipeline;

[0025] S6, repeat S1-S5 to complete the connection of the two connecting pipes to the two oil pipelines, so that the two connecting pipes are respectively connected to the oil tank and the engine;

[0026] S7, the machine body is fixedly installed on the vehicle body.

[0027] The fuel consumption analyzer and its usage method of the present invention have the following advantages over the prior art:

[0028] (1) By setting up a support pipe and a flexible pipe, and by using the rotational cooperation of the two, not only can the outer diameter of the end of the connecting pipe away from the machine body be reduced, but the port of the oil pipeline can also be expanded, making it easier to connect the oil consumption analyzer with the oil pipeline, thereby improving the installation efficiency of this oil consumption analyzer.

[0029] (2) By setting a limit rod and setting one end of the limit rod to be stepped, not only can the rotation range of the live pipe be adjusted, but the movement gap can also be sealed to prevent the live pipe from rotating after the oil pipeline is connected to the connecting pipe.

[0030] (3) By setting a fixed sleeve and a sealing cylinder, the fixing firmness of the oil pipeline and the main pipe can be improved, thereby improving the connection sealing between the oil consumption analyzer and the oil pipeline. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0043] like Figure 1-9 As shown, an oil consumption analyzer of the present invention includes a body 1 and a connecting pipe 2.

[0044] The main body 1 is the main structure of this fuel consumption analyzer, which is equipped with a fuel consumption analysis and detection device to detect fuel consumption.

[0045] The machine body 1 needs to be installed on the vehicle body. To improve the fixation strength between the machine body 1 and the vehicle body, it is preferable to fix multiple fixing plates 11 on the machine body 1, and to open a reinforcement hole 101 on the side of the machine body 1 closest to the vehicle body. A support plate 12 and a spring 13 are slidably installed within the reinforcement hole 101, with the spring 13 positioned on the side of the support plate 12 furthest from the vehicle body, providing support. Figure 8 As shown, by using the round hole of the fixing plate 11 and the bolt, the fixing plate 11 can be connected to the vehicle body, thereby fixing the machine body 1 to the vehicle body. When the machine body 1 is installed on the vehicle body, the supporting plate 12 will be supported by the elastic force of the spring 13 and will support the vehicle body. This supporting force, together with the pressure of the bolt on the fixing plate 11, can also prevent the machine body 1 from vibrating.

[0046] Preferably, an airbag 121 can be fixedly installed on the side of the abutment plate 12 away from the vehicle body, so that the airbag 121 is located inside the spring 13 and selectively abuts against the body 1. The airbag 121 is made of an elastic material, such as... Figure 9 As shown, when the abutment plate 12 abuts against the vehicle body below, it will move upward, causing the airbag 121 to deform. During the deformation process, the airbag 121 will apply elastic force to the abutment plate 12. Combined with the elastic force of the original spring 13 on the abutment plate 12, the abutment plate 12 and the vehicle body will have a stronger abutment force, thereby improving its fixing effect. At the same time, the deformation of the airbag 121 will also embed into the gap of the spring 13, so that the spring 13 will also receive the elastic force of the airbag 121 when it contracts, thus achieving the same effect of improving the abutment plate 12 and the vehicle body abutment force.

[0047] Two connecting pipes 2 are provided for connection to the oil supply pipeline. The two connecting pipes 2 are respectively connected to the oil tank and the engine. The two connecting pipes 2 are mounted on the machine body 1. Each connecting pipe 2 includes a main pipe 21, a support pipe 22, and a flexible connecting pipe 23. The main pipe 21 is fixedly mounted on the machine body 1, and the two main pipes 21 are connected through the machine body 1. The support pipe 22 is fixedly mounted at the end of the main pipe 21 away from the machine body 1. The middle position of the flexible connecting pipe 23 is rotatably connected to the middle position of the support pipe 22. Both the flexible connecting pipe 23 and the support pipe 22 have arc-shaped cross-sections, and a movable gap 201 is provided between them. The side of the support pipe 22 away from the center line of the main pipe 21 is flush with the main pipe 21, and the side of the flexible connecting pipe 23 away from the center line of the main pipe 21 is selectively flush with the main pipe 21. Figure 3 As shown, when the right end of the connector 23 is rotated downwards, the outer diameter of the right end of the connecting pipe 2 becomes relatively small, making it easier to fit the oil pipeline onto the right end of the connector 23 and the support pipe 22. At the same time, since the middle position of the connector 23 is rotatably connected to the middle position of the support pipe 22, when the oil pipeline is fitted onto the right end of the connector 23 and the support pipe 22, the port of the oil pipeline can be expanded by repeatedly pressing down the left end of the connector 23, making it easier to fit the oil pipeline onto the outside of the connecting pipe 2, thus improving the installation efficiency of this oil consumption analyzer.

[0048] like Figure 1 As shown, a limiting rod 24 can also be installed in the connecting pipe 2. A groove 202 is opened on the outside of the main pipe 21, so that the limiting rod 24 is slidably installed in the groove 202 and selectively seals the movable gap 201. That is, after the oil pipeline is completely covered by the main pipe 21, the support pipe 22 and the connecting pipe 23, the limiting rod 24 can be slid to seal the movable gap 201, so that the connecting pipe 23 can no longer rotate, so as not to affect the sealing of the oil pipeline. Specifically, it is preferable that the end of the limiting rod 24 away from the machine body 1 is stepped, such as Figure 7 As shown, the right end of the limiting rod 24 is stepped. When the limiting rod 24 is slidable, the different positions on the upper side of its stepped end can resist the movable tube 23, which can also limit the rotation range of the movable tube 23.

[0049] When the oil pipeline is fitted onto the main pipe 21, pipe clamps are usually used to fix the oil pipeline. Similarly, a fixing sleeve 25 can be set in the connecting pipe 2, so that the fixing sleeve 25 fits on the outside of the main pipe 21 and is fixedly connected to the limiting rod 24. There is a gap between the fixing sleeve 25 and the main pipe 21 to fix the oil pipeline connected to the connecting pipe 2. The method of fixing the oil pipeline by simply relying on the gap between the fixing sleeve 25 and the main pipe 21 has the problem of relatively weak fixation. In order to solve this problem, it is preferable to open a slot 203 at the end of the fixing sleeve 25 away from the machine body 1, and connect a locking nut 251 to the outside of the fixing sleeve 25 by thread engagement. The locking nut 251 is tightened with the fixing sleeve 25 to make the connection between the fixing sleeve 25 and the oil pipeline more secure.

[0050] During the connection process between the oil pipeline and the connecting pipe 2, the oil pipeline needs to be fitted onto the outside of the main pipe 21 first, and then the limiting rod 24 is slid. Since the limiting rod 24 is small and inconvenient to operate, the driving nut 211 can be connected to the outside of the main pipe 21 by thread engagement. The driving nut 211 selectively abuts against the fixing sleeve 25, and the fixed sleeve 25 is moved by turning the driving nut 211.

[0051] The presence of the gap 201 will inevitably weaken the sealing performance of the connecting pipe 2. To improve its sealing effect, a sealing cylinder 26 can be installed in the connecting pipe 2. The sealing cylinder 26 is slidably installed inside the main pipe 21 and fixedly connected to the limiting rod 24. The sealing cylinder 26 can slide between the support pipe 22 and the flexible connecting pipe 23 to seal the gap 201. Figure 6 As shown, after the oil pipeline is installed on the connecting pipe 2, its outer side is fixed and sealed by the fixing sleeve 25, while the movable gap 201 between the inner support pipe 22 and the live pipe 23 is sealed by the sealing cylinder 26 to prevent fuel leakage.

[0052] The method of using the fuel consumption analyzer of the present invention is as follows:

[0053] S1, unscrew the locking nut 251 from the fixing sleeve 25 and put it on the oil pipeline, turn the drive nut 211 toward the side closer to the machine body 1, slide the limit rod 24 toward the side closer to the machine body 1, so that the limit rod 24 is disengaged from the movable gap 201.

[0054] S2, rotate the side of the live connector 23 away from the body 1 toward the side closer to the support pipe 22, and fit the end of the oil pipeline onto the outside of the support pipe 22 and the end of the live connector 23 away from the body 1.

[0055] S4, press the end of the live connector 23 near the body 1 repeatedly, and rotate the oil pipeline simultaneously, using the separation of the live connector 23 and the support pipe 22 to expand the port of the oil pipeline;

[0056] S4, slide the oil pipeline towards the side closer to the machine body 1. When the end of the oil pipeline moves to the outside of the main pipe 21, turn the drive nut 211 away from the machine body 1 to push the fixed sleeve 25 to slide, so that the end of the oil pipeline is located between the main pipe 21 and the fixed sleeve 25.

[0057] S5, tighten the locking nut 251 on the oil pipeline to the outside of the fixing sleeve 25 to fix the oil pipeline;

[0058] S6, repeat S1-S5 to complete the connection of the two connecting pipes 2 to the two oil supply lines, so that the two connecting pipes 2 are connected to the oil tank and the engine respectively.

[0059] S7, fix the machine body 1 to the vehicle body.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
