Description

Technical Field

[0001] The present invention relates to the technical field of vehicle fuel consumption detection, and particularly relates to a fuel consumption analyzer and a method for using the same. Background Art

[0002] Fuel consumption is one of the important indicators for drivers to understand the vehicles they drive. It not only allows drivers to timely judge vehicle failures, but also helps to promote drivers to improve their driving habits. Usually, fuel consumption is detected by a fuel consumption analyzer installed on the vehicle.

[0003] In order to improve the accuracy of fuel consumption detection, an in-vehicle fuel consumption meter disclosed in the invention patent with the patent publication number CN114812717A is usually adopted and installed in the fuel pipeline between the vehicle fuel tank and the engine. Currently, common in-vehicle fuel consumption meters usually adopt a fuel pipeline quick connector disclosed in the utility model with the patent publication number CN217813718U to achieve the quick connection between the fuel pipeline and the in-vehicle fuel consumption meter.

[0004] It can be seen from the attached drawings of the above utility model that in order to achieve the quick connection between the connector and the fuel pipeline, the outer side of the connector is set in a gourd shape. However, the fuel pipeline often has relatively strong flexibility, and the difference between the inner diameter of the fuel pipeline and the outer diameter of the connector is relatively large. Before installing it, it is necessary to expand the port of the fuel pipeline by means of heating or tool expansion, etc., which reduces the connection efficiency between the fuel pipeline and the connector. Summary of the Invention

[0005] In view of this, the present invention provides a fuel consumption analyzer and a method for using the same, which can achieve the quick connection between the fuel consumption analyzer and the fuel pipeline and improve the installation efficiency of the fuel consumption analyzer.

[0006] The technical solution of the present invention is realized as follows: On the one hand, the present invention provides a fuel consumption analyzer, including a body and two connecting pipes. The two connecting pipes are arranged on the body. The connecting pipe includes a main pipe, a support pipe and a movable pipe. Among them,

[0007] The main pipe is fixedly arranged on the body, and the two main pipes are communicated with each other through the body;

[0008] The support pipe is fixedly arranged at one end of the main pipe away from the body;

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

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

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

[0012] More preferably, the connecting pipe further includes a fixing sleeve. The fixing sleeve is sleeved on the outer side 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 slotted hole is formed at one 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 thread fit.

[0014] More preferably, a driving nut is connected to the outer side of the main pipe by thread fit, and the driving nut selectively abuts against the fixing sleeve.

[0015] More preferably, the connecting pipe further includes a sealing cylinder. The sealing cylinder is slidably arranged in 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 block the movable gap.

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

[0017] A reinforcing hole is formed on one side of the machine body close to the vehicle body. A resisting plate and a spring are slidably arranged in the reinforcing hole. The spring is located on the side of the resisting plate away from the vehicle body and abuts against it.

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

[0019] In the second aspect, the present invention provides a method for using the above fuel consumption analyzer, which is characterized by including the following steps:

[0020] S1. Unscrew the locking nut from the fixing sleeve and sleeved on the oil pipeline. Screw the driving nut in the direction close to the machine body side, and slide the limiting rod in the direction close to the machine body side to make the limiting rod disengage from the movable gap;

[0021] S2. Rotate the side of the flexible pipe away from the body towards the side close to the support pipe, and sleeve the end of the oil pipeline on the outside of the support pipe and the end of the flexible pipe away from the body.

[0022] S3. Reciprocally press the end of the flexible pipe close to the body, and synchronously rotate the oil pipeline. Expand the port of the oil pipeline by using the separation between the flexible pipe and the support pipe.

[0023] S4. Slide the oil pipeline towards the side close to the body. When the end of the oil pipeline moves to the outside of the main pipe, screw the drive nut away from the 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. Screw the locking nut on the oil pipeline to the outside of the fixed sleeve to fix the oil pipeline.

[0025] S6. Repeat S1 - S5 to complete the connection of the two connecting pipes and the two oil pipelines, so that the two connecting pipes are respectively communicated with the fuel tank and the engine.

[0026] S7. Fix and install the body on the vehicle body.

[0027] The fuel consumption analyzer and its usage method of the present invention have the following beneficial effects compared with the prior art:

[0028] (1) By setting the support pipe and the flexible pipe, and using their rotational cooperation, not only can the outer diameter of the end of the connecting pipe away from the body be reduced, but also the port of the oil pipeline can be expanded, making the connection between the fuel consumption analyzer and the oil pipeline more convenient, thus improving the installation efficiency of the present fuel consumption analyzer.

[0029] (2) By setting the limiting rod and setting one end of the limiting rod in a stepped shape, not only can the rotation range of the flexible pipe be adjusted, but also the moving gap can be blocked to prevent the flexible pipe from rotating after the oil pipeline is connected to the connecting pipe.

[0030] (3) By setting the fixed sleeve and the sealing cylinder, the fixing firmness between the oil pipeline and the main pipe can be improved, thereby enhancing the connection tightness between the present fuel consumption analyzer and the oil pipeline. Description of the Drawings

[0042] The following will clearly and completely describe the technical solutions in the present invention in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1-9 shown, a fuel consumption analyzer of the present invention includes a body 1 and a connecting pipe 2.

[0044] Among them, the body 1 is the main structure of the fuel consumption analyzer, and a fuel consumption analysis and detection device is arranged inside to detect the fuel consumption.

[0045] The body 1 needs to be installed on the vehicle body. In order to improve the fixing firmness between the body 1 and the vehicle body, it is preferably to fixedly arrange a plurality of fixing plates 11 on the body 1, and a reinforcing hole 101 is opened on one side of the body 1 close to the vehicle body. A supporting plate 12 and a spring 13 are slidably arranged in the reinforcing hole 101, and the spring 13 is located on the side of the supporting plate 12 away from the vehicle body and abuts against it; as Figure 8 shown, by using the cooperation of the round hole of the fixing plate 11 and the bolt, the fixing plate 11 can be connected to the vehicle body, so as to fix the body 1 on the vehicle body. When the body 1 is installed on the vehicle body, the supporting plate 12 will abut against the vehicle body under the elastic force of the spring 13. This abutting force, combined with the pressure of the bolt on the fixing plate 11, can also prevent the body 1 from vibrating.

[0046] Preferably, an airbag 121 can be fixedly arranged on the side of the supporting 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, as Figure 9 shown, when the supporting plate 12 abuts against the vehicle body below, it will move upward, so that the airbag 121 deforms. During the deformation process of the airbag 121, an elastic force will be applied to the supporting plate 12. Combined with the elastic force of the original spring 13 on the supporting plate 12, the abutting force between the supporting plate 12 and the vehicle body is stronger, so as to improve its fixing effect. At the same time, the deformation of the airbag 121 will also be embedded in the gap of the spring 13, so that the spring 13 will also receive the elastic force of the airbag 121 when contracting, and the effect of improving the abutting force between the supporting plate 12 and the vehicle body is also achieved.

[0047] There are two connecting pipes 2, which are used to communicate with the oil pipeline. The two connecting pipes 2 are respectively communicated with the fuel tank and the engine. The two connecting pipes 2 are arranged on the body 1. The connecting pipe 2 includes a main pipe 21, a support pipe 22 and a flexible pipe 23. The main pipe 21 is fixedly arranged on the body 1. The two main pipes 21 are communicated through the body 1. The support pipe 22 is fixedly arranged at one end of the main pipe 21 away from the body 1. The middle position of the flexible pipe 23 is rotatably connected to the middle position of the support pipe 22. The cross-sections of the flexible pipe 23 and the support pipe 22 are both arc-shaped, and there is an activity gap 201 between them. One side of the support pipe 22 away from the center line of the main pipe 21 is flush with the main pipe 21. One side of the flexible pipe 23 away from the center line of the main pipe 21 is selectively flush with the main pipe 21; As Figure 3 shown, when the right end of the flexible pipe 23 is rotated downward, the outer diameter of the right end of the connecting pipe 2 becomes relatively smaller, which is more convenient to sleeved the oil pipeline on the right ends of the outer sides of the flexible pipe 23 and the support pipe 22. At the same time, since the middle position of the flexible pipe 23 is rotatably connected to the middle position of the support pipe 22, when the oil pipeline is sleeved on the right ends of the outer sides of the flexible pipe 23 and the support pipe 22, by pressing the left end of the flexible pipe 23 reciprocally, the port of the oil pipeline can be expanded, so that the oil pipeline can be more conveniently sleeved on the outer side of the connecting pipe 2, improving the installation efficiency of this fuel consumption analyzer.

[0048] As Figure 1 shown, a limiting rod 24 can also be arranged in the connecting pipe 2. A sliding groove 202 is opened on the outer side of the main pipe 21, so that the limiting rod 24 is slidably arranged in the sliding groove 202 and selectively blocks the activity gap 201. That is, after the oil pipeline is completely sleeved on the outer sides of the main pipe 21, the support pipe 22 and the flexible pipe 23, the limiting rod 24 can be slid to block the activity gap 201, so that the flexible pipe 23 can no longer rotate, so as not to affect the sealing performance of the oil pipeline; Specifically, it is preferably that one end of the limiting rod 24 away from the body 1 is stepped. As Figure 7 shown, the right end of the limiting rod 24 is stepped. When the limiting rod 24 is slid, the rotation range of the flexible pipe 23 can also be limited by the abutment of different positions on the upper side of its stepped end against the flexible pipe 23.

[0049] When the oil pipeline is sleeved on the main pipe 21, pipe clamps are usually needed to fix the oil pipeline. Similarly, a fixing sleeve 25 can be arranged in the connecting pipe 2, so that the fixing sleeve 25 is sleeved on the outside of the main pipe 21 and fixedly connected with the limiting rod 24. There is a gap between the fixing sleeve 25 and the main pipe 21 for fixing the oil pipeline connected to the connecting pipe 2. The method of fixing the oil pipeline solely by the gap between the fixing sleeve 25 and the main pipe 21 has the problem of relatively weak fixing firmness. To solve this problem, it is preferable to open a slotted groove 203 at one end of the fixing sleeve 25 away from the machine body 1, and a locking nut 251 is connected to the outside of the fixing sleeve 25 by thread fit. By tightening the locking nut 251 with the fixing sleeve 25, the fixing sleeve 25 is more firmly connected to the oil pipeline.

[0050] During the connection process of the oil pipeline and the connecting pipe 2, the oil pipeline needs to be sleeved on the outside of the main pipe 21 first, and then the limiting rod 24 is slid. Since the shape of the limiting rod 24 is small and inconvenient to operate, a driving nut 211 can be connected to the outside of the main pipe 21 by thread fit. The driving nut 211 selectively abuts against the fixing sleeve 25, and the fixing sleeve 25 is driven to move by screwing the driving nut 211.

[0051] The existence of the movable gap 201 will inevitably weaken the sealing performance of the connecting pipe 2. To improve its sealing effect, a sealing cylinder 26 can also be arranged in the connecting pipe 2, so that the sealing cylinder 26 is slidably arranged in the main pipe 21 and fixedly connected with the limiting rod 24. The sealing cylinder 26 can slide between the support pipe 22 and the movable connecting pipe 23 to block the movable gap 201. As Figure 6 shown, after the oil pipeline is installed on the connecting pipe 2, its outside is fixedly sealed by the fixing sleeve 25, and the movable gap 201 between the inner support pipe 22 and the movable connecting pipe 23 is sealed by the sealing cylinder 26 to prevent fuel leakage.

[0052] The usage method of an oil consumption analyzer of the present invention is as follows:

[0053] S1. Unscrew the locking nut 251 from the fixing sleeve 25, sleeve it on the oil pipeline, screw the driving nut 211 in the direction close to the machine body 1, and slide the limiting rod 24 in the direction close to the machine body 1 so that the limiting rod 24 disengages from the movable gap 201.

[0054] S2. Rotate the side of the movable connecting pipe 23 away from the machine body 1 in the direction close to the support pipe 22, and sleeve the end of the oil pipeline on the outside of the support pipe 22 and the end of the movable connecting pipe 23 away from the machine body 1.

[0055] S4. Reciprocally press the end of the movable connecting pipe 23 close to the machine body 1 and simultaneously rotate the oil pipeline to expand the port of the oil pipeline by the separation of the movable connecting pipe 23 and the support pipe 22.

[0056] S4. Slide the oil pipeline in the direction towards the side closer to the body 1. When the end of the oil pipeline moves to the outside of the main pipe 21, turn the drive nut 211 in the direction away from the 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. Screw the locking nut 251 on the oil pipeline to the outside of the fixed sleeve 25 to fix the oil pipeline;

[0058] S6. Repeat S1 - S5 to complete the connection of the two connecting pipes 2 and the two oil pipelines, so that the two connecting pipes 2 are respectively connected to the fuel tank and the engine;

[0059] S7. Fix the body 1 on the vehicle body.

[0060] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
