Description

Technical Field

[0001] The present invention relates to the technical field of fuel tank cap debugging, and in particular to a method for debugging a fuel tank cap of a new energy vehicle. Background Art

[0002] With the development of new energy vehicles, more and more gasoline-powered vehicles are being converted to new energy vehicles. Since these converted new energy vehicles are identical to their gasoline-powered counterparts, they often retain the original fuel tank cap. Because the two vehicles are identical, to reduce manufacturing costs, components are often molded using the same molds as the gasoline-powered vehicles.

[0003] Currently, the fuel tank cap of a fuel-powered vehicle is typically opened and closed mechanically. Specifically, a lock latch is provided on the inner wall of the fuel tank cap, and a locking rod is provided on the vehicle body. Pressing the fuel tank cap engages the lock latch and the locking rod to close the cap, and pulling a cable disengages the locking rod and lock latch to open the cap.

[0004] like Figure 1 As shown, during the production of new energy vehicles, since the original oil tank cap 1 is retained, it is necessary to debug the oil tank cap 1 during the production process to check whether the appearance dimensions of the oil tank cap 1 and the front door 2 and the middle door 3 meet the requirements.

[0005] The existing fuel tank cap debugging method is: first, install the fuel tank cap opening mechanism (fuel tank cap opening switch, cable and other components) on the vehicle. The structural characteristics and working principle of the fuel tank cap opening mechanism are the same as those of the original fuel vehicle, that is, the cable is pulled by the fuel tank cap opening switch, and then the locking rod on the vehicle body is pulled by the cable, so that the locking rod is disengaged from the lock hole on the lock buckle, and then the fuel tank cap is opened; then the fuel tank cap is adjusted; then the fuel tank cap 1 is closed to check whether its appearance with the front door 2 and the middle door 3 meets the design requirements; if not, the above steps are repeated and debugging is performed repeatedly until the design requirements are met; finally, after the debugging is completed, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable) is removed.

[0006] Currently, when debugging the fuel tank cap, a fuel tank cap opening mechanism (fuel tank cap opening switch, cable and other components) that is no longer needed in the later stage needs to be installed on the vehicle. After the debugging is completed, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable and other components) needs to be removed from the vehicle. Therefore, the debugging efficiency is low and the debugging cost is high.

[0007] In summary, how to solve the problem of low debugging efficiency and high debugging cost of crude oil tank caps of new energy vehicles has become a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the Invention

[0008] In view of this, an object of the present invention is to provide a method for debugging a crude oil tank cap of a new energy vehicle, so as to solve the problems of low debugging efficiency and high debugging cost of the crude oil tank cap of a new energy vehicle.

[0009] To achieve the above-mentioned object, the present invention provides a method for debugging a fuel tank cap of a new energy vehicle. The inner wall of the fuel tank cap is provided with a lock catch, and the lock catch is used to cooperate with a locking rod on the vehicle body. When the lock catch is engaged with the locking rod, the fuel tank cap is closed, and when the lock catch is disengaged from the locking rod, the fuel tank cap is opened. The lock catch has an initial state in which it can be engaged with the locking rod.

[0010] The debugging method of the crude oil tank cover of the new energy vehicle comprises the following steps:

[0011] Step S1, deforming the lock buckle, wherein the lock buckle is in a deformed state and cannot be coupled to the lock rod on the vehicle body;

[0012] Step S2, repeatedly adjusting the fuel tank cap until the external dimensions of the fuel tank cap and the front door and middle door of the vehicle meet the design requirements;

[0013] Step S3, restoring the deformed lock buckle from the deformed state to the initial state, so that the restored lock buckle can be combined with the lock rod on the vehicle body;

[0014] Step S4: Press the fuel tank cap to engage the restored lock catch with the lock rod on the vehicle body, so that the fuel tank cap remains in a normally closed state.

[0015] Preferably, in step S1, deforming the lock buckle includes manually bending the lock buckle until it is deformed.

[0016] Preferably, in step S3, restoring the deformed lock buckle to its initial state from the deformed state comprises manually bending the deformed lock buckle to its initial state.

[0017] The present invention has the following beneficial effects:

[0018] It can be seen from the above technical solution that compared with the background technology introduction, the debugging method of the crude oil tank cap of the new energy vehicle does not require the additional installation of fuel tank cap opening components such as fuel tank cap opening switch and pull rope. The debugging process is very simple and convenient, which not only improves the debugging efficiency but also reduces the debugging cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The drawings described herein are used to provide a further understanding of the present application and constitute a part of the present application. The illustrative embodiments and descriptions of the present application are used to explain the present application and do not constitute an improper limitation on the present application. In the drawings:

[0021] Figure 2This is a structural diagram of the fuel tank cap and the locking rod on the vehicle body. DETAILED DESCRIPTION

[0022] The core of the present invention is to provide a method for debugging the crude oil tank cover of a new energy vehicle to solve the problems of low debugging efficiency and high debugging cost of the crude oil tank cover of a new energy vehicle.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, since the new energy vehicle is modified from the original fuel vehicle, in order to reduce manufacturing costs (such as mold making costs), the modified new energy vehicle retains the original fuel tank cap 1. Therefore, during the manufacturing process, the fuel tank cap 1 needs to be adjusted so that the external dimensions of the fuel tank cap 1, the front door 2, and the middle door 3 meet the design requirements.

[0025] like Figure 2 As shown, the inner wall of the fuel tank cap 1 is provided with a lock catch 4, which is used to cooperate with a lock rod 5 on the vehicle body. When the lock catch 4 is engaged with the lock rod 5, the fuel tank cap 1 is closed, and when the lock catch 4 is disengaged from the lock rod 5, the fuel tank cap 1 is opened.

[0026] The existing debugging method for the fuel tank cap 1 is: first, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable and other components) is installed on the vehicle. The structural characteristics and working principle of the fuel tank cap opening mechanism are the same as those of the original fuel vehicle, that is, the cable is pulled by the fuel tank cap opening switch, and then the locking rod 5 on the vehicle body is pulled by the cable, so that the locking rod 5 is disengaged from the lock hole on the lock buckle 4, and then the fuel tank cap 1 is opened; then the fuel tank cap 1 is adjusted; then the fuel tank cap 1 is closed to check whether its appearance with the front door 2 and the middle door 3 meets the design requirements; if not, the above steps are repeated and debugging is performed repeatedly until the design requirements are met; finally, after the debugging is completed, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable) is removed.

[0027] It is easy to understand that in the prior art, when debugging the fuel tank cap 1, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable) must first be installed on the vehicle, which will no longer be used. After debugging is completed, the fuel tank cap opening mechanism (fuel tank cap opening switch, cable) must be removed from the vehicle. This debugging process is very cumbersome, with low debugging efficiency and high debugging costs. In view of this, the applicant has improved the debugging method of the fuel tank cap 1. The following is a detailed description of the improved debugging method for the crude oil tank cap of a new energy vehicle.

[0028] like Figure 1-2As shown, the inner wall of the fuel tank cap 1 is provided with a lock buckle 4, which is used to cooperate with the lock rod 5 on the vehicle body. When the lock buckle 4 is combined with the lock rod 5, the fuel tank cap 1 is closed, and when the lock buckle 4 is disengaged from the lock rod 5, the fuel tank cap 1 is opened. The lock buckle 4 has an initial state that can be combined with the lock rod 5.

[0029] An embodiment of the present invention provides a method for debugging a crude oil tank cap of a new energy vehicle, comprising the following steps:

[0030] In step S1 , the lock buckle 4 is deformed. The lock buckle 4 is in a deformed state. The deformed lock buckle 4 ′ cannot be combined with the lock rod 5 on the vehicle body.

[0031] Since the deformed lock buckle 4 ′ cannot be combined with the lock rod 5 on the vehicle body, the fuel tank cap 1 can be opened freely at this time, making it convenient to adjust the fuel tank cap 1 .

[0032] Step S2: repeatedly adjusting the fuel tank cap 1 until the external dimensions of the fuel tank cap 1 and the front door 2 and the middle door 3 of the vehicle meet the design requirements.

[0033] The adjustment method of the fuel tank cap 1 is the same as that in the prior art and will not be described in detail here.

[0034] Step S3 , restoring the deformed lock buckle 4 ′ from the deformed state to the initial state, so that the restored lock buckle 4 can be combined with the lock rod 5 on the vehicle body.

[0035] When the fuel tank cap 1 is adjusted to meet the design requirements, the deformed lock buckle 4 ′ is restored to its original state, so that the restored lock buckle 4 can be combined with the lock rod 5 on the vehicle body, making it convenient to close the fuel tank cap 1 later.

[0036] Step S4 , pressing the fuel tank cap 1 to make the restored lock catch 4 engage with the lock rod 5 on the vehicle body, so that the fuel tank cap 1 remains in a normally closed state.

[0037] Since the new energy vehicle does not need to be refueled, the fuel tank cap 1 will not be opened after it is closed.

[0038] It can be seen from the above technical solution that compared with the background technology introduction, the debugging method of the crude oil tank cap of the new energy vehicle does not require the additional installation of fuel tank cap opening components such as fuel tank cap opening switch and pull rope. The debugging process is very simple and convenient, which not only improves the debugging efficiency but also reduces the debugging cost.

[0039] In some specific embodiments, in step S1, the lock buckle 4 is deformed, including manually bending the lock buckle 4 until it is deformed. In step S3, the deformed lock buckle 4' is restored to its initial state from the deformed state, including manually bending the deformed lock buckle 4' to its initial state. Deforming the lock buckle 4 or restoring the deformed lock buckle 4' to its initial state by manually bending is very convenient and significantly improves the efficiency of fuel tank cap debugging. It should be noted that, in order to restore the deformed lock buckle 4' to its initial state by manually bending, it is only necessary to restore the deformed lock buckle 4' to approximately its initial state, as long as the restored lock buckle 4 can be combined with the locking rod 5 on the vehicle body.
