[0001] This application relates to the automotive field, and in particular to a car body repair sticker and a car body repair method. Background Technology

[0002] During daily use, cars inevitably experience some damage and collisions, resulting in dents, deformations, or breaks in the car body. This not only affects the appearance but may also compromise safety. Therefore, repairing damaged car bodies is essential.

[0003] In related technologies, the first method of car body repair involves using sheet metal repair tools to uniformly process the damage—sanding, puttying, sanding, painting, and baking—regardless of the size of the damage. However, this method suffers from drawbacks such as a complex and cumbersome repair process, long processing time, and high repair costs. The second method involves using a hot melt gun to heat dented or deformed plastic parts (such as bumpers) if they are damaged or deformed due to a collision. This high temperature reduces the hardness of the plastic parts, increasing their toughness and facilitating repair. However, this method can only repair plastic parts and has limited applicability. Summary of the Invention

[0020] The repair layer is used to adhere to the entrance of the hole to be repaired on the vehicle body to form a closed space containing the hole. After the liquid repair material used to repair the hole is introduced into the closed space, it receives an externally 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. The state of the solid repair material reaching the preset state indicates that the vehicle body repair is successful.

[0021] The insulating layer serves to guide the liquid repair material into the enclosed space and prevent the liquid repair material from leaking out of the vehicle body repair sticker. Furthermore, the insulating layer also prevents electric shock to the user, ensuring user safety.

[0022] Optionally, a first through hole is provided between the insulating layer and the repair layer, and an inlet tube is embedded in the insulating layer.

[0030] Optionally, the vehicle body repair sticker further includes a fixing device disposed on the insulating layer;

[0031] The fixing device is used to fix different sections of the conductive coil at different positions to adjust the area surrounded by the conductive coil.

[0033] Optionally, the fixing device is an adhesive device, which is disposed on the surface of the insulating layer near the repair layer.

[0034] This application provides a vehicle body repair method. First, a repair sticker is affixed to the entrance of the hole to be repaired on the vehicle body to form a closed space containing the hole. Next, a liquid repair material for repairing the hole is injected into the closed space. Then, an electric current is applied to the liquid repair material to solidify it into a solid repair material.

This application utilizes a material that can gradually harden from a liquid state to a solid state when energized as the vehicle body repair material. This material is injected into the hole to be repaired, and the state of the repair material is continuously observed after energization. If the state of the repair material reaches the expected state (e.g., the resistance tends to be constant, or the current passing through it tends to be constant), the hole repair can be determined to be complete, i.e., the vehicle body repair is successful. This method has many advantages, including simple repair method, high repair efficiency, low repair cost, and strong applicability. Attached Figure Description

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0042] Figure 1 This is a flowchart illustrating a vehicle body repair method according to an embodiment of this application, see reference. Figure 1 The vehicle body repair method of this application includes the following steps:

[0043] Step S11: Apply the repair sticker to the entrance of the hole 6 to be repaired on the vehicle body to form a closed space containing the hole 6.

[0044] In this embodiment, for the holes 6 that appear in the damaged parts of the vehicle body, a repair sticker can be pasted at the entrance of the hole 6 to enclose the hole 6 in a closed space.

[0045] For example, in Figure 2 In the hole 6 shown, a repair sticker can be pasted along the dotted line at the first entrance 4 of the hole 6, and another repair sticker 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 This is a schematic diagram of a hole 6 shown in one embodiment of this application.

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

[0047] In this embodiment, the repair patch is equipped with an introduction device, which allows external liquid repair material to be introduced into the enclosed space. This introduction device can be a flexible tube or other type of introduction device; this embodiment does not impose any specific limitations on it.

[0048] Among these, a metal-hydrazone hybrid can be selected as a liquid repair material. Its characteristics are as follows: a precious metal (such as platinum) is corroded in an acid solution, forming tiny channels and pores within the material. Then, a nanostructured material is infused into the entire pore framework, while simultaneously filling each micropore with a conductive liquid (such as a simple salt solution or weak acid solution). The resulting material is a hybrid of metal and liquid, called a metal-hydrazone hybrid. When an electric current passes through it, the atomic bonds on the metal surface strengthen, increasing the material's hardness.

[0049] Of course, in actual implementation, other repair materials with similar functions to metal-water composites (the material hardness increases when energized) can also be selected. This embodiment does not impose specific restrictions on this.

[0050] Step S13: Input an electric current into the liquid repair material to solidify it 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 supply current to the liquid repair material.

[0052] The operating voltage of the external power supply can be any voltage within a preset range, such as 220V. This preset range can be set according to actual needs. If a voltage within the preset range cannot be directly obtained in certain scenarios, it can be converted using a transformer.

[0053] In step S13, current is continuously input to the liquid repair material through an external power source, causing the liquid repair material to gradually solidify into a solid repair material.

[0054] Step S14: When the solid repair material reaches the preset state, the vehicle body repair is confirmed to be successful.

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

[0056] In steps S13-S14, the liquid repair material fills the entire cavity 6. As the liquid repair material gradually solidifies, its resistance continuously changes. The resistance of the liquid repair material is R = L / (σ*A), where L is the thickness of the liquid repair material within the cavity 6, and A is the cross-sectional area of ​​the cavity 6. Figure 2 The cross-sectional areas of multiple points in the central hole 6 were comprehensively evaluated to obtain the cross-sectional area A of hole 6. σ is the electrical 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 refers to the stable state of the solid repair material. Based on extensive experience, this application has identified at least two conditions that indicate the achievement of the preset state, which will be described in detail 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 has reached the preset state and the vehicle body repair is successful.

[0059] In practice, the resistance of the solid repair material can be determined in any way. This embodiment does not impose specific restrictions on the method of detecting resistance.

[0060] In another embodiment, to quickly and conveniently determine whether the state of the solid repair material has reached 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 a preset state and the car body repair is successful. In this embodiment, to determine whether the resistance of the solid repair material tends to be constant, we can 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 has also reached 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 hole 6 is repaired and the car body repair is complete. This method does not require resistance detection, which is more convenient.

[0062] The statement that the current tends to be constant does not mean that the current is absolutely constant at a certain value X. When the current fluctuates within a preset range above and below the value X, that is, when the current is always within the interval (Xb) to (X+b), it can also be said that the current is in a state of tending to be constant. Here, b can be set according to actual needs.

[0063] Similarly, the statement that the resistance tends 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 around the value Y, that is, when the resistance is always within the interval (Yc) to (Y+c), it can also be said that the resistance is in a state of tending to be constant. Here, c can be set according to actual needs. After confirming that the car body repair is successful, the current input can be paused and the repair sticker can be removed.

[0064] The method described in this application can be controlled and executed by any type of mechanical device, such as a robot, robotic arm, etc.

[0065] The vehicle body repair method of this application involves first affixing a repair sticker to the entrance of the hole 6 to be repaired on the vehicle body to form a closed space containing the hole 6; then, injecting a liquid repair material for repairing the hole 6 into the closed space; next, applying an electric current to the liquid repair material to solidify it into a solid repair material; finally, when the solid repair material reaches a preset state, the vehicle body repair is considered successful. This application utilizes a material that can gradually harden from a liquid to a solid state when energized as the vehicle body repair material. This material is injected into the hole 6 to be repaired, and the state of the repair material is continuously observed after energization. If the state of the repair material reaches the expected state, the vehicle body repair is considered complete, i.e., the vehicle body repair is successful. This method has many advantages, including simple repair method, high repair efficiency, low repair cost, and strong applicability.

[0066] In one embodiment, in conjunction with the above embodiments, the repair patch includes a first repair patch and a second repair patch. The first repair patch is connected to the positive terminal of the power supply via a wire, and the second repair patch is connected to the negative terminal of the power supply via a wire. The hole 6 includes a first inlet 4 and a second inlet 5.

[0067] Based on this, step S11 may include:

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

[0069] exist Figure 2 As shown, a first repair patch is applied at point 4 of the first entrance, and a second repair patch is applied at point 5 of the second entrance. This will result in the following: Figure 3 The diagram shown. Figure 3 This is a schematic diagram of the structure of a car body repair sticker according to an embodiment of this application. Figure 3 The image shown is a side view of a repair patch.

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

[0071] The first and second repair patches can be the same or different. If they are different, the only difference is that the second repair patch does not contain an infusion tube, thus saving on the production cost of the repair patch.

[0072] In one embodiment, in conjunction with the above embodiments, the first repair patch is provided with an inlet tube 3. When the first repair patch is pasted onto the first inlet 4, one end of the inlet tube 3 is located inside the closed space, and the other end is located outside the closed space.

[0073] The inlet tube 3 is the inlet device mentioned earlier.

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

[0075] Liquid repair material for repairing holes 6 is injected into one end of the inlet tube 3 located outside the closed space, allowing the liquid repair material to enter the closed space through the other end located inside the closed space.

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

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

[0078] Specifically, after affixing the repair sticker to the entrance of the hole 6 to be repaired on the vehicle body, and before injecting the liquid repair material for repairing the hole 6 into the enclosed space, the method of this application further includes:

[0079] Adjust the positions of each section of the conductive coil 23 so that the first inlet is within the area surrounded by the conductive coil 23.

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

[0081] In this embodiment, the range of the conductive coil 23 can be large or small. By adjusting the position of each part of the conductive coil 23, the conductive coil 23 can be distributed along the outer edge of the entrance of the hole 6 and just include the entrance area. In this way, when the liquid repair material is injected, the liquid repair material can be prevented from leaking out of the hole 6, and a large amount of 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 can be included within it. a can be set according to actual needs.

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

[0084] Reference Figure 3 The vehicle body repair sticker of this application includes a tightly adhered insulating layer 1 and a repair layer 2.

[0085] Repair layer 2 is used to adhere to the entrance of the hole 6 to be repaired on the vehicle body to form a closed space containing the hole 6. After the liquid repair material used to repair the hole 6 is introduced into the closed space, it receives an externally 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 means that the vehicle body repair is successful.

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

[0087] Secondly, the insulation layer also prevents electric shock to users, ensuring their safety. The user in this context could be, for example, a worker repairing a car 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] Repair layer 2 is composed of an adhesive patch 21, a sealing ring 22, and a conductive coil 23. The adhesive patch 21, sealing ring 22, and conductive coil 23 are all distributed on the surface of the insulating cloth, and are all on the same plane. In other words, the vehicle body repair patch of this application is generally composed of an insulating cloth, an adhesive patch 21, a sealing ring 22, and a conductive coil 23.

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

[0091] In this embodiment, a first through hole is provided between the insulating layer 1 and the repair layer 2. An inlet tube 3 is embedded in the insulating layer 1, with one end of the inlet tube 3 extending out of the insulating layer 1 and the other end extending into the repair layer 2 through the first through hole. The inlet tube 3 is used to introduce liquid repair material into the enclosed space.

[0092] Installation of inlet tube 3 as follows Figure 3 As shown. Of course, besides Figure 3 There are other installation methods besides the one described above, and this embodiment does not impose any specific restrictions on them.

[0093] Secondly, a second through hole is provided between the insulating layer 1 and the repair layer 2. The conductive coil 23 is connected to an 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 region of the repair layer 2, and the position of the conductive coil 23 can be as follows: Figure 4 As shown. Figure 4 The conductive coil 23 is ring-shaped; in fact, the shape of the conductive coil 23 can be adjusted to any shape. Figure 4 In the diagram, the bold black ring represents the conductive coil, and the light gray area is the region where the position of the conductive coil 23 can be adjusted.

[0095] In this embodiment, in order to adjust the shape of the conductive coil 23, the car body repair sticker is also provided with a fixing device, which is disposed 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 suction device, which is embedded in the insulating layer 1 or disposed on the surface of the insulating layer 1 away from the repair layer 2.

[0097] The magnetic attraction device can provide magnetic attraction to the conductive coil 23, thereby firmly attaching the conductive coil 23 to the insulating cloth.

[0098] In another embodiment, the fixing device is an adhesive device, which is disposed on the surface of the insulating layer 1 near the repair layer 2.

[0099] The adhesive device can be, for example, Velcro, which can firmly attach the conductive coil 23 to the insulating cloth.

[0100] In this embodiment, the car body repair sticker can include two types. The only difference between the two types is that one type is designed with an inlet tube 3 (i.e., the first repair sticker), while the other type does not contain an inlet tube 3 (i.e., the second repair sticker). The rest are exactly the same.

[0101] The adhesive patch 21 is located at the outer edge of the repair layer 2. The adhesive patch 21 is used to achieve a tight bond between the insulating layer 1 and the surrounding surface area of ​​the inlet. The specific location of the adhesive patch 21 is as follows: Figure 4 The dark gray area is shown. Figure 4 The adhesive sticker 21 is ring-shaped, but in reality, the shape of the adhesive sticker 21 can be set according to actual needs.

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

[0103] The following is a detailed example of how to use car body repair stickers to repair a car body.

[0104] Reference Figure 3 For the hole 6 shown, firstly, a first repair patch containing the inlet tube 3 is pasted onto the first inlet 4, and then a second repair patch without the inlet tube 3 is pasted onto the second inlet 5. Next, the conductive coil 23 in each repair patch is adjusted. For example, different sections of the conductive coil 23 can be fixed and attracted to different positions by moving a magnetic suction device, or different sections of the conductive coil 23 can be pasted to different positions on the insulating cloth by an adhesive device, so that the entire inlet is contained within the conductive coil 23. After adjustment, the metal water-coated body is injected through the inlet tube 3. After the metal water-coated body is injected, the first repair patch is connected to the positive terminal of the power supply, and the second repair patch is connected to the negative terminal of the power supply, thus forming a complete current loop. Under the stimulation of the current, the metal water-coated body gradually solidifies. During this process, the resistance of the metal water-coated body changes continuously, causing the current to change continuously. When the current stops changing, it indicates that the resistance of the metal water-coated body has reached a stable state. At this time, the performance of the metal water-coated body has also reached a stable state, and the current output can be paused. The two repair patches can then be removed, thus completing the body repair.

[0105] This application designs a car body repair sticker and provides a car body repair solution based on the sticker. The solution utilizes a material that gradually hardens from a liquid to a solid state when electricity is applied as the car body repair material. This material is injected into the hole 6 to be repaired. After applying electricity, the state of the repair material is continuously observed. If the state of the repair material reaches the expected state, the hole 6 can be determined to be repaired, i.e., the car body repair is successful. This solution eliminates the need for sanding, puttying, sanding, painting, and baking processes, 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.
