Description

Technical Field

[0001] This application relates to the field of automotive painting technology, and more particularly to an auxiliary painting fixture for a charging cover. Background Technology

[0002] Electric vehicles, including pure electric vehicles or hybrid electric vehicles, are equipped with a corresponding charging cover at the charging port. When not charging, the charging cover covers the charging port to protect it, and when charging is needed, the charging cover can be opened to expose the charging port.

[0003] Since the charging cover is an external covering, it needs to be the same color as the car body paint to ensure color consistency.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0042] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0043] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0044] It should be noted that electric vehicles, including pure electric vehicles or hybrid electric vehicles, are equipped with a corresponding charging cover at the charging port. When not charging, the charging cover covers the charging port to protect it, and when charging is needed, the charging cover can be opened to expose the charging port.

[0045] Since the charging cover is an external covering, it needs to be the same color as the car body paint to ensure color consistency. In related technologies, the car body and the charging cover are painted separately, which can easily lead to color differences between the charging cover and the car body paint after painting.

[0046] Based on this, this application proposes an auxiliary painting fixture 100 for a charging cover. Through the combined use of the elastic member 3 and the fixing member 2, the charging cover can be fixedly installed on the vehicle body so that the charging cover can be painted together with the vehicle body. This solves the problem of excessive color difference between the charging cover and the vehicle body, and makes the paint appearance of the charging cover meet the quality requirements.

[0047] The auxiliary painting fixture 100 for a charging cover plate proposed in this application is described below with reference to the accompanying drawings.

[0048] like Figures 1-3 As shown, the auxiliary painting fixture 100 for a charging cover according to an embodiment of this application includes: a fixture body 1, a fixing member 2, and an elastic member 3. The fixing member 2 is fixedly connected to the fixture body 1 and is used to fixally connect to the vehicle body. The elastic member 3 is fixedly connected to the fixture body 1. Along the first direction X, the elastic member 3 has a first snap-fit ​​portion 31 and a second snap-fit ​​portion 32 that are arranged opposite to each other and spaced apart. The first snap-fit ​​portion 31 is used to snap-fit ​​with the first slot of the charging cover, and the second snap-fit ​​portion 32 is used to snap-fit ​​with the second slot of the charging cover, so that the elastic member 3 is abutted and installed between the first slot and the second slot along the first direction X.

[0049] Specifically, the auxiliary painting fixture 100 consists of a fixture body 1, a fixing component 2, and an elastic component 3. The fixing component 2 and the elastic component 3 are both fixedly installed on the fixture body 1. The fixing installation methods include, but are not limited to, rivet connection, bolt connection, welding, etc.

[0050] Furthermore, the fastener 2 is used to fix the charging cover to the vehicle body. In order to enable the charging cover to be painted together with the vehicle body, this application fixes the charging cover to the elastic member 3.

[0051] It should be noted that the charging cover has an external surface and a non-external surface that are set opposite to each other. During the spraying operation, only the external surface needs to be painted. Therefore, by fixing the non-external surface with the elastic element 3, interference with the spraying of the external surface can be prevented.

[0052] Further, refer to Figure 1As shown, along the first direction X, the elastic member 3 has a first latching portion 31 and a second latching portion 32 that are arranged opposite to each other and spaced apart. It can be understood that the non-exterior surface of the charging cover is provided with a first slot corresponding to the first latching portion 31 and a second slot corresponding to the second latching portion 32. When the elastic member 3 and the charging cover are assembled together, the first latching portion 31 of the elastic member 3 is latched and assembled into the first slot of the charging cover, and the second latching portion 32 of the elastic member 3 is latched and assembled into the second slot of the charging cover.

[0053] Furthermore, after the elastic element 3 is snapped into the charging cover, the elastic element 3 is abutted between the first slot and the second slot along the first direction X. It is understood that the elastic element 3 will undergo a certain elastic deformation under the abutting action of the first slot and the second slot. Therefore, the elastic element 3 will apply opposite forces to the first slot and the second slot respectively. According to the principle of mechanics, if the opposite force applied by the elastic element 3 to the first slot through the first snap-fit ​​part 31 is F1, then the opposite force applied by the elastic element 3 to the second slot through the second snap-fit ​​part 32 is F2. Here, F1 is equal to F2, and the direction of F1 is opposite to the direction of F2.

[0054] With this setup, the charging cover can be fixed to the elastic element 3 under the support of the elastic element 3. Then, the auxiliary painting fixture 100 is fixed to the vehicle body through the fixing element 2, so that the charging cover can be fixedly installed on the vehicle body. This allows the charging cover to be painted together with the vehicle body, thus solving the problem of excessive paint color difference between the charging cover and the vehicle body, and ensuring that the paint appearance of the charging cover meets the quality requirements.

[0055] In some embodiments of this application, the tooling body 1 may be made of materials such as, but not limited to, stainless steel, aluminum alloy, and hard plastic. The tooling body 1 may be constructed as an L-shaped structure. The fastener 2 may be made of materials such as, but not limited to, stainless steel, aluminum alloy, and hard plastic. The elastic element 3 may be made of materials such as, but not limited to, elastic steel plate and elastic rubber. The fastener 2 and the elastic element 3 are spaced apart along the first direction X to prevent interference during installation.

[0056] In some embodiments of this application, such as Figure 1 and Figure 2As shown, the elastic member 3 includes a first segment 33, a second segment 34, and a third segment 35 connected in sequence. The second segment 34 is fixedly connected to the tooling body 1. The first segment 33 has a first snap-fit ​​portion 31, and the third segment 35 has a second snap-fit ​​portion 32. Along the first direction X, the first segment 33 and the third segment 35 are arranged opposite each other and are located on both sides of the second segment 34. Along the second direction Y, the first segment 33 and the third segment 35 are located on the same side of the second segment 34. The second direction Y is perpendicular to the first direction X. A first bending portion 331 is formed at the connection between the first segment 33 and the second segment 34, and a second bending portion 351 is formed at the connection between the third segment 35 and the second segment 34.

[0057] Specifically, such as Figure 1 and Figure 2 As shown, the elastic element 3 can be constructed as a 1.5mm thick spring steel plate. The second segment 34 of the elastic element 3 extends along the first direction X and is fixedly connected to the tooling body 1. Further, along the first direction X, the first segment 33 and the third segment 35 are arranged opposite each other and are located on both sides of the second segment 34. Along the second direction Y, the first segment 33 and the third segment 35 are located on the same side of the second segment 34. The second direction Y is perpendicular to the first direction X.

[0058] Furthermore, a first bend 331 is formed at the connection between the first segment 33 and the second segment 34, and a second bend 351 is formed at the connection between the third segment 35 and the second segment 34. It can be understood that the first bend 331 forms a first included angle, and the second bend 351 forms a second included angle. Since the first segment 33 and the third segment 35 are respectively located on both sides of the second segment 34 along the first direction X, and along the second direction Y, the first segment 33 and the third segment 35 are located on the same side of the second segment 34, as... Figure 2 As shown, the first included angle and the second included angle are both greater than 90°. With this configuration, the first segment 33, the second segment 34 and the third segment 35 are constructed as an elastic structure. When a force is applied to the first segment 33 and the third segment 35, according to the principles of mechanics, the first segment 33 and the third segment 35 are compressed and deformed to generate a reaction force.

[0059] Furthermore, the first segment 33 has a first engaging portion 31, and the third segment 35 has a second engaging portion 32. When the first engaging portion 31 is engaged in the first slot and the second engaging portion 32 is engaged in the second slot, the elastic member 3 is abutted and installed between the first slot and the second slot along the first direction X. That is, the first slot applies an abutting force to the first segment 33 through the first engaging portion 31, and the second slot applies an abutting force to the third segment 35 through the second engaging portion 32. Thus, the first segment 33 is compressed towards the third segment 35 along the first direction X under the abutting action, and the third segment 35 is compressed towards the first segment 33 along the first direction X under the abutting action. According to the principle of mechanics, the first segment 33 can apply a reverse force F1 to the first slot through the first engaging portion 31, and the third segment 35 can apply a reverse force F2 to the second slot through the second engaging portion 32. Here, F1 is equal to F2, and the direction of F1 is opposite to the direction of F2.

[0060] In some embodiments of this application, since the first segment 33 and the third segment 35 are respectively disposed on both sides of the second segment 34 along the first direction X, and along the second direction Y, the first segment 33 and the third segment 35 are disposed on the same side of the second segment 34, such as... Figure 2 As shown, there is a third included angle α between the first segment 33 and the third segment 35, which satisfies the relationship: 54°≤α≤58°. This setting ensures that the first segment 33 and the third segment 35 have good deformation capacity, thereby ensuring the rebound force of the elastic element 3, so that the elastic element 3 can firmly fix the charging cover.

[0061] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the charging cover includes a first mounting plate and a second mounting plate. The first mounting plate has a first slot, and the second mounting plate has a second slot. The first engaging portion 31 includes a first insert portion 311 and a first limiting portion 312 connected to each other. The first insert portion 311 is located on the side of the first limiting portion 312 away from the second segment 34. The first insert portion 311 is adapted to be inserted into the first slot, and the first limiting portion 312 is adapted to abut against the first mounting plate. The second engaging portion 32 includes a second insert portion 321 and a second limiting portion 322 connected to each other. The second insert portion 321 is located on the side of the second limiting portion 322 away from the second segment 34. The second insert portion 321 is adapted to be inserted into the second slot, and the second limiting portion 322 is adapted to abut against the second mounting plate.

[0062] Specifically, along the first direction X, a first mounting plate and a second mounting plate of the charging cover are disposed opposite to each other, with a first slot formed on the first mounting plate and a second slot formed on the second mounting plate. Further, as... Figure 1As shown, the first latching portion 31 includes a first insertion portion 311 and a first limiting portion 312 connected to each other. The first insertion portion 311 is located outside the first limiting portion 312, that is, the first insertion portion 311 is located at the free end of the first segment 33. It should be noted that the size of the first insertion portion 311 is smaller than the size of the first slot, and the size of the first limiting portion 312 is larger than the size of the first slot. Similarly, the second latching portion 32 includes a second insertion portion 321 and a second limiting portion 322 connected to each other. The second insertion portion 321 is located outside the second limiting portion 322, that is, the second insertion portion 321 is located at the free end of the third segment 35. It should be noted that the size of the second insertion portion 321 is smaller than the size of the second slot, and the size of the second limiting portion 322 is larger than the size of the first slot.

[0063] When the first latching part 31 is assembled with the first slot, the first insertion part 311 is inserted into the first slot, and the first limiting part 312 abuts against the first mounting plate. When the second latching part 32 is assembled with the second slot, the second insertion part 321 is inserted into the second slot, and the second limiting part 322 abuts against the second mounting plate.

[0064] This configuration enables the first snap-fit ​​part 31 to be snap-fitted into the first slot and the second snap-fit ​​part 32 to be snap-fitted into the second slot. The snap-fit ​​method is simple and convenient, and easy to disassemble. After the charging cover is finished being sprayed, it can be quickly removed and replaced with the charging cover to be sprayed.

[0065] In some embodiments of this application, the maximum distance between the first limiting part 312 and the second limiting part 322 along the first direction X is L, and the maximum distance between the first card slot and the second card slot along the first direction X is M, satisfying the relationship: L > M.

[0066] Specifically, such as Figure 1 As shown, along the first direction X, the first limiting part 312 and the second limiting part 322 are arranged opposite to each other and spaced apart, and the maximum distance between the first limiting part 312 and the second limiting part 322 is L. Along the first direction X, the first card slot and the second card slot are arranged opposite to each other and spaced apart, and the maximum distance between the first card slot and the second card slot is M. The relationship is satisfied: L>M. That is to say, the maximum distance between the first limiting part 312 and the second limiting part 322 is greater than the maximum distance between the first card slot and the second card slot. For example, the maximum distance between the first limiting part 312 and the second limiting part 322 is 158mm, and the maximum distance between the first card slot and the second card slot is 111mm.

[0067] With this configuration, when the first snap-fit ​​part 31 of the first segment 33 is assembled with the first slot, the first insertion part 311 is inserted into the first slot, and the first limiting part 312 abuts against the first mounting plate. When the second snap-fit ​​part 32 of the third segment 35 is assembled with the second slot, since the maximum distance between the first limiting part 312 and the second limiting part 322 is greater than the maximum distance between the first slot and the second slot, the third segment 35 needs to be bent toward the first segment 33 along the first direction X so that the second insertion part 321 is inserted into the second slot, and the second limiting part 322 abuts against the second mounting plate. This ensures that the elastic member 3 has sufficient elasticity and shape change during installation to ensure the rebound force of the elastic member 3.

[0068] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the fastener 2 has an elastic groove 21, which is used to snap and fix it to the vehicle body.

[0069] Specifically, the fastener 2 can be constructed as a 1.5mm thick spring steel plate. The fastener 2 is fixedly connected to the vehicle body through the elastic slot 21. Optionally, the fastener 2 can be fixedly installed on the rear cover sheet metal of the vehicle body. It is necessary to ensure that the width of the elastic slot 21 is less than the thickness of the sheet metal. For example, the width of the elastic slot 21 is 2.7mm and the thickness of the sheet metal is 6.34mm. With this setting, when the elastic slot 21 is assembled with the sheet metal, it can ensure the clamping force of the elastic slot 21 on the sheet metal, ensuring the stability of the connection between the auxiliary painting fixture 100 and the vehicle body. At the same time, the snap-fit ​​assembly also facilitates the installation and disassembly of the auxiliary painting fixture 100 and the vehicle body, so that the installation and disassembly time of the auxiliary painting fixture 100 meets the production rhythm of the vehicle.

[0070] In some embodiments of this application, the fastener 2 includes a first clamping plate and a second clamping plate that are arranged opposite to each other and spaced apart, with an elastic groove 21 formed between the first clamping plate and the second clamping plate. That is, the elastic groove 21 is composed of the first clamping plate and the second clamping plate that are arranged opposite to each other and spaced apart. With this arrangement, the sheet metal is clamped by the first clamping plate and the second clamping plate, resulting in a large force-bearing area and high stability.

[0071] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the fastener 2 includes a connecting plate 22 and an elastic buckle 23. Along the first direction X, the elastic buckle 23 extends from the end edge of the connecting plate 22 facing the elastic member 3 and bends away from the elastic member 3. The gap between the elastic buckle 23 and the connecting plate 22 forms an elastic groove 21.

[0072] Specifically, an elastic buckle 23 extends from the connecting plate 22 by bending. The gap between the elastic buckle 23 and the connecting plate 22 forms an elastic groove 21. When the connecting plate 22 and the elastic buckle 23 move away from each other under external force, the elastic groove 21 deforms and increases in size, making it easier for the sheet metal to be inserted into the elastic groove 21. After the external force is removed, the connecting plate 22 and the elastic buckle 23 move closer together to clamp the sheet metal.

[0073] Therefore, the sheet metal can be easily clamped by the elastic deformation of the elastic buckle 23, making clamping convenient and quick. The connecting plate 22 and the elastic buckle 23 can be manually pried apart to deform and move away from each other; alternatively, the elastic slot 21 can be directly engaged with the sheet metal to force the elastic slot 21 to deform and move away from each other.

[0074] In some embodiments of this application, the number of elastic buckles 23 extending from the connecting plate 22 can be one or more to increase the clamping and fixing effect on the sheet metal. In this embodiment, there are two elastic buckles 23. By setting multiple elastic buckles 23, the clamping effect on the sheet metal can be improved, thereby making the connection between the fastener 2 and the sheet metal more stable.

[0075] In some embodiments of this application, such as Figure 2 As shown, the elastic buckle 23 has a protrusion facing the connecting plate 22. This design reduces the local thickness of the elastic slot 21, thereby enhancing the clamping effect of the protrusion on the sheet metal.

[0076] In some embodiments of this application, such as Figures 1-3 As shown, the auxiliary painting fixture 100 also includes a conductive ring 4, which is fixedly connected to the fixture body 1 and is arranged around the charging cover plate along the circumference of the charging cover plate.

[0077] Specifically, the conductive ring 4 can be welded to the tooling body 1, or it can be fixedly connected to the tooling body 1 by bolts; no specific limitation is made here. The conductive ring 4 can be made of conductive materials such as stainless steel, and is arranged around the charging cover plate along the circumference of the charging cover plate. For example, the conductive ring 4 has a ring structure formed by steel bars with a diameter of 3mm around the charging cover plate.

[0078] With this setup, when the painting robot paints the charging cover, the conductive ring 4 can effectively absorb excess paint applied by the electrostatic spraying robot, preventing problems such as thick edges and bubbles from appearing on the charging cover.

[0079] In some embodiments of this application, the inner circumferential surface of the conductive ring 4 is spaced apart from the outer circumferential surface of the charging cover. Specifically, the conductive ring 4 is arranged around the charging cover. Optionally, the inner circumferential surface of the conductive ring 4 is spaced apart from the outer circumferential surface of the charging cover, thus ensuring that there is a certain gap between the conductive ring 4 and the charging cover. This allows for better adsorption of excess paint on the edge of the charging cover, which helps to further reduce problems such as thick edges and blistering on the edge of the charging cover.

[0080] In some embodiments of this application, the distance between the inner circumferential surface of the conductive ring 4 and the outer circumferential surface of the charging cover is d, which satisfies the relationship: 10mm≤d≤20mm.

[0081] Specifically, when the distance between the inner circumferential surface of the conductive ring 4 and the outer circumferential surface of the charging cover is too far or too close, it is not conducive to the conductive ring 4 adsorbing the paint on the edge of the charging cover. In order to prevent the distance between the inner circumferential surface of the conductive ring 4 and the outer circumferential surface of the charging cover from being too far or too close, the distance d between the inner circumferential surface of the conductive ring 4 and the outer circumferential surface of the charging cover is set in the range of 10mm-20mm along the radial direction of the conductive ring 4. For example, the distance between the inner circumferential surface of the conductive ring 4 and the outer circumferential surface of the charging cover is... The distance can be 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, or 20mm.
