[0041] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] Figure 1 is a flow chart of a vehicle body repair method shown in an embodiment of the present application, referring to Figure 1 The vehicle body repair method of the present application comprises the following steps:

[0043] Step S11 : Paste the repair patch on the entrance of the hole 6 to be repaired on the vehicle body to form a closed space including the hole 6 .

[0044] In this embodiment, for the hole 6 that appears at the damaged part of the vehicle body, a repair patch can be pasted at the entrance of the hole 6, so as to surround the hole 6 in a closed space.

[0045] For example, in Figure 2 In the hole 6 shown, a repair patch can be pasted along the dotted line at the first entrance 4 of the hole 6, and another repair patch can be pasted along the dotted line at the second entrance 5 of the hole 6, so that the entire hole 6 forms a closed space. Figure 2 FIG. 6 is a schematic diagram of a hole 6 according to an embodiment of the present application.

[0046] Step S12: injecting liquid repair material for repairing the hole 6 into the closed space.

[0047] In this embodiment, the repair patch is provided with an introduction device, through which the external liquid repair material can be introduced into the closed space. The introduction device can be a hose, or other types of introduction devices, which are not specifically limited in this embodiment.

[0048] Among them, liquid repair materials can be selected from metal water conjugates. The material characteristics are: precious metal materials (such as platinum) are corroded in acid solution, and tiny pipes and holes are formed in the material. Then a nanostructured material is poured into the entire channel framework, and each micropore is also filled with conductive liquid (such as simple salt solution or weak acid solution). Finally, a material that is a hybrid of metal and liquid is obtained, which is called metal water conjugate. When an electric current passes through, the atomic bonds on the metal surface will be strengthened and the hardness of the material will increase.

[0049] Of course, in actual implementation, other repair materials with similar functions to the metal water-connected body (the hardness of the material increases when electricity is applied) can also be selected, and this embodiment does not impose specific restrictions on this.

[0050] Step S13: inputting electric current into the liquid repair material to solidify the liquid repair material into a solid repair material.

[0051] In this embodiment, the repair patch is connected to an external power source via a wire, and the external power source is used to provide current to the liquid repair material.

[0052] The working voltage of the external power supply may be any voltage within a preset range, for example, 220 V. The preset range may be set according to actual needs. If the voltage within the preset range cannot be directly obtained in some scenarios, it may be converted by a transformer.

[0053] Step S13 is executed to continuously input current into the liquid repair material through an external power source, so that the liquid repair material gradually solidifies into a solid repair material.

[0054] Step S14: When the state of the solid repair material reaches a preset state, it is determined that the vehicle body repair is successful.

[0055] In this embodiment, other loads are ignored and the liquid repair material is the only load of the external power supply.

[0056] In step S13-step S14, the liquid repair material fills the entire hole 6. In the process of the liquid repair material gradually changing into a solid repair material, the resistance of the liquid repair material continues to change. The resistance of the liquid repair material R = L / (σ*A), L is the thickness of the liquid repair material in the hole 6. A is the cross-sectional area of ​​the hole 6, for example, Figure 2 The cross-sectional areas of the pores 6 are comprehensively evaluated to obtain the cross-sectional area A of the pores 6. σ is the conductivity, which is related to the type, concentration, temperature, shape and size of the material. It can be seen that R is the nonlinear resistance.

[0057] The preset state is the state in which the solid repair material reaches a stable state. In this application, at least two situations that can indicate that the preset state has been reached are determined through a large amount of experience, which will be specifically described below: In one embodiment, step S14 may include:

[0058] When the resistance of the solid repair material tends to be constant, it is determined that the state of the solid repair material reaches a preset state and the vehicle body is repaired successfully.

[0059] In specific implementation, the resistance of the solid repair material may be determined in any manner, and this embodiment does not impose any specific limitation on the method for detecting the resistance.

[0060] In another embodiment, in order to quickly and conveniently determine whether the state of the solid repair material reaches a preset state, step S14 may include:

[0061] When the current passing through the solid repair material tends to be constant, it is determined that the state of the solid repair material has reached the preset state and the body repair has been successful. In this embodiment, to determine whether the resistance of the solid repair material tends to be constant, it is possible to first determine whether the magnitude of the current passing through the solid repair material tends to be constant. According to the formula I=U / R, when both U and R tend to be constant, it means that the current I also reaches a constant value. If I changes from a continuously changing state at the beginning to a constant state, it means that the performance of the solid repair material has reached a stable state. At this time, it means that the hole 6 has been repaired and the body repair has been completed. This method does not require the detection of resistance and is more convenient.

[0062] Among them, the current tending to be constant does not mean that the current is absolutely unchanged at a certain value X. When the current fluctuates within a preset range above and below the value X, that is, the current is always within the interval (Xb) to (X+b), it can also indicate that the current is in a constant state, wherein b can be set according to actual needs.

[0063] Similarly, the resistance tending to be constant does not mean that the resistance is absolutely constant at a certain value Y. When the resistance fluctuates within a preset range above and below the value Y, that is, the resistance is always within the interval (Yc) to (Y+c), it can also mean that the resistance is in a constant state, where c can be set according to actual needs. After confirming that the car body repair is successful, the current input can be suspended and the repair patch can be removed.

[0064] The method of the present application can be executed by controlling any type of mechanical equipment, such as a robot, a robotic arm, etc.

[0065] To implement the vehicle body repair method of the present application, firstly, a repair patch is pasted on the entrance of the hole 6 to be repaired on the vehicle body to form a closed space containing the hole 6; then, a liquid repair material for repairing the hole 6 is injected into the closed space; then, an electric current is input into the liquid repair material to solidify the liquid repair material into a solid repair material; finally, when the state of the solid repair material reaches a preset state, it is determined that the vehicle body repair is successful. In the present application, a material that can gradually harden from a liquid state to a solid state when powered on is used as a repair material for the vehicle body. The material is injected into the hole 6 to be repaired, and the state of the repair material is continuously observed after power is turned on. If the state of the repair material reaches the expected state, it can be determined that the vehicle body repair is completed, that is, the vehicle body repair is successful. This method has many advantages such as simple repair method, high repair efficiency, low repair cost and strong applicability.

[0066] In combination with the above embodiments, in one implementation, the repair patch includes a first repair patch and a second repair patch, the first repair patch is connected to the positive pole of the power supply through a wire, the second repair patch is connected to the negative pole of the power supply through a wire, and the hole 6 includes a first entrance 4 and a second entrance 5.

[0067] On this basis, step S11 may include:

[0068] The first repair patch is pasted on the first inlet 4 , and the second repair patch is pasted on the second inlet 5 .

[0069] exist Figure 2 The first repair patch is pasted on the first inlet 4 and the second repair patch is pasted on the second inlet 5, so that the following can be obtained: Figure 3 Figure shown. Figure 3 It is a schematic structural diagram of a car body repair patch shown in one embodiment of the present application. Figure 3 Shown is a side view of a repair patch.

[0070] Next, the first repair patch is connected to the positive pole of the power supply through a wire, and the second repair patch is connected to the negative pole of the power supply through a wire. In this way, a complete current loop can be formed between the external power supply and the repair material. By detecting the current in the current loop, it can be determined whether the resistance of the repair material tends to a stable state.

[0071] The first repair patch and the second repair patch may be the same or different. If they are different, the only difference between the two is that the second repair patch does not contain an introduction tube, thereby saving the production cost of the repair patch.

[0072] In combination with the above embodiments, in one implementation, an introduction tube 3 is provided in the first repair patch. When the first repair patch is attached to the first inlet 4, one end of the introduction tube 3 is located in the closed space, and the other end is located outside the closed space.

[0073] The introduction tube 3 is the introduction device mentioned above.

[0074] Accordingly, a liquid repair material for repairing the hole 6 is injected into the closed space, including:

[0075] Liquid repair material for repairing the hole 6 is injected into one end of the introduction tube 3 located outside the closed space, so that the liquid repair material enters the closed space through the other end located inside the closed space.

[0076] In this embodiment, an introduction tube 3 may be provided in the repair patch to facilitate the injection of the repair material.

[0077] In combination with the above embodiments, in one implementation manner, a conductive coil 23 is provided in the first repair patch, the conductive coil 23 is connected to a wire, and the conductive coil 23 is used to adjust the repair area on the vehicle body.

[0078] Specifically, after the repair patch is attached to the entrance of the hole 6 to be repaired on the vehicle body, and before the liquid repair material for repairing the hole 6 is injected into the closed space, the method of the present application further includes:

[0079] The positions of the various sections of the conductive coil 23 are adjusted so that the first inlet is located within the enclosed area of ​​the conductive coil 23 .

[0080] The conductive coil 23 is horizontally arranged in the repair patch and can be flexibly moved.

[0081] In this embodiment, the range of the conductive coil 23 can be large or small. By adjusting the positions of various parts of the conductive coil 23, the conductive coil 23 can be distributed just along the outer edge of the entrance of the hole 6 and just include the entrance area. In this way, when injecting liquid repair material, the liquid repair material can be prevented from leaking out of the hole 6, and the waste of more liquid repair material can be avoided.

[0082] For example, the distance between the conductive coil 23 and the edge of the inlet can be adjusted to a, and the inlet is included, and a can be set according to actual needs.

[0083] The structure of the vehicle body repair patch of the present application will be described in detail below.

[0084] Reference Figure 3 The vehicle body repair patch of the present application comprises an insulating layer 1 and a repair layer 2 which are closely fitted.

[0085] The repair layer 2 is used to be pasted on the entrance of the hole 6 to be repaired on the vehicle body to form a closed space containing the hole 6, and after the liquid repair material used to repair the hole 6 is introduced into the closed space, it receives external input current and transmits current stimulation to the liquid repair material in the closed space to solidify the liquid repair material into a solid repair material until the state of the solid repair material reaches a preset state. When the state of the solid repair material reaches the preset state, it indicates that the vehicle body repair is successful.

[0086] The insulating layer 1 is used to introduce the liquid repair material into the closed space and prevent the liquid repair material from leaking out of the vehicle body repair patch.

[0087] Secondly, the insulating layer also has the function of preventing users from getting electric shock, thereby ensuring the safety of users, such as workers repairing the vehicle body.

[0088] In this embodiment, the insulating layer 1 is an insulating cloth, and the thickness of the insulating cloth can be set according to actual needs.

[0089] The repair layer 2 is a layer composed of an adhesive patch 21, a sealing ring 22 and a conductive coil 23. The adhesive patch 21, the sealing ring 22 and the conductive coil 23 are all arranged on the surface of the insulating cloth, and the adhesive patch 21, the sealing ring 22 and the conductive coil 23 are all in the same plane. That is, the vehicle body repair patch of the present application is generally composed of the insulating cloth, the adhesive patch 21, the sealing ring 22 and the conductive coil 23.

[0090] The specific structure of the repair layer is as follows Figure 4 shown. Figure 4 This is a schematic diagram of a repair layer structure shown in an embodiment of the present application.

[0091] In this embodiment, a first through hole is correspondingly provided between the insulating layer 1 and the repairing layer 2, and an introduction tube 3 is buried in the insulating layer 1, with one end of the introduction tube 3 extending out of the insulating layer 1 and the other end extending into the repairing layer 2 through the first through hole. The introduction tube 3 is used to introduce the liquid repairing material into the closed space.

[0092] The installation of the introduction pipe 3 is as follows Figure 3 Of course, in addition to Figure 3 There may be other installation methods, and this embodiment does not specifically limit this.

[0093] Secondly, a second through hole is correspondingly opened between the insulating layer 1 and the repairing layer 2, and the conductive coil 23 is connected to the external power source through a wire passing through the second through hole to receive the current provided by the external power source.

[0094] The conductive coil 23 is disposed in the central area of ​​the repair layer 2. The position of the conductive coil 23 can be as follows: Figure 4 shown. Figure 4 The conductive coil 23 in the embodiment is annular. In fact, the shape of the conductive coil 23 can be adjusted to any shape. Figure 4 In the figure, the bold black ring represents the conductive coil, and the light grey area is the area where the conductive coil 23 can adjust its position.

[0095] In this embodiment, in order to adjust the shape of the conductive coil 23, the vehicle body repair patch is further provided with a fixing device, which is arranged on the insulating layer 1. The fixing device can fix different sections of the conductive coil 23 at different positions to adjust the surrounding area of ​​the conductive coil 23.

[0096] In one embodiment, the fixing device is a magnetic device, which is buried in the insulating layer 1 or disposed on a surface of the insulating layer 1 away from the repair layer 2 .

[0097] The magnetic attraction device can provide magnetic attraction force to the conductive coil 23, so that the conductive coil 23 is tightly adsorbed on the insulating cloth.

[0098] In another embodiment, the fixing device is an adhesive device, and the adhesive device is arranged on the surface of the insulating layer 1 close to the repair layer 2 .

[0099] The sticking device may be, for example, Velcro, which can stick the conductive coil 23 tightly onto the insulating cloth.

[0100] In this embodiment, the vehicle body repair patch may include two types, the only difference between the two types is that one is designed with an introduction tube 3 (ie, the first repair patch) and the other does not include an introduction tube 3 (ie, the second repair patch), and the rest of the parts are exactly the same.

[0101] The adhesive patch 21 is located at the outer edge of the repair layer 2, and the adhesive patch 21 is used to achieve close adhesion between the insulating layer 1 and the surrounding surface area of ​​the inlet. The position of the adhesive patch 21 is as follows: Figure 4 The dark grey area is shown. Figure 4 The adhesive patch 21 is annular in shape. In fact, the shape of the adhesive patch 21 can be set according to actual needs.

[0102] A sealing ring 22 is provided between the maximum enclosed area of ​​the conductive coil 23 and the adhesive patch 21. The sealing ring 22 is used to prevent the liquid repair material from leaking out of the vehicle body repair patch. The position of the sealing ring 22 can be as follows: Figure 4 shown. Figure 4 The sealing ring 22 is annular. In fact, the shape of the sealing ring 22 can be set according to actual needs.

[0103] The following is a complete example to explain in detail how to use the car body repair patch to repair the car body.

[0104] Reference Figure 3 The hole 6 shown is first pasted on the first entrance 4 with a first repair patch containing an introduction tube 3, and then pasted on the second entrance 5 with a second repair patch without an introduction tube 3. Next, adjust the conductive coil 23 in each repair patch, for example, by moving the magnetic suction device, fix the different sections of the conductive coil 23 at different positions, or paste the different sections of the conductive coil 23 at different positions on the insulating cloth through the pasting device, so that the entire entrance is finally contained in the conductive coil 23. After adjustment, start injecting the metal water conjugate through the introduction tube 3. After the injection of the metal water conjugate is completed, connect the first repair patch to the positive pole of the power supply, and connect the second repair patch to the negative pole of the power supply, so as to form a complete current loop. Under the stimulation of the current, the metal water conjugate gradually solidifies. In this process, the resistance of the metal water conjugate changes continuously, causing the current to change continuously. When it is detected that the current no longer changes, it means that the resistance of the metal water conjugate reaches a stable state. At this time, the performance of the metal water conjugate also reaches a stable state. The current output can be suspended and the two repair patches are removed. At this point, the car body repair is completed.

[0105] The present application designs a car body repair patch and provides a car body repair solution based on the car body repair patch. The solution uses a material that can gradually harden from a liquid state to a solid state when powered on as a repair material for the car body, injects the material into the hole 6 to be repaired, and continuously observes the state of the repair material after power is turned on. If the state of the repair material reaches the expected state, it can be determined that the hole 6 has been repaired, that is, the car body has been repaired successfully. The solution does not require processes such as grinding, scraping putty, grinding, painting, and baking varnish, and is not limited to the repair of plastic car bodies (parts). It has many advantages such as simple repair method, high repair efficiency, low repair cost, and strong applicability.
