[0043] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] like Figures 1 to 3As shown, according to an embodiment of the present disclosure, a door painting limiting tool 10 is proposed, comprising: a limiting portion 110, having a first limiting end 110a and a second limiting end 110b, the first limiting end 110a is used to be inserted into the first mounting hole 201' of the B-pillar 20' or the second mounting hole of the C-pillar, and the second limiting end 110b is used to be inserted into the inter-plate gap 101' of the door 10' to be painted, and the inter-plate gap 101' is the gap between the inner plate 11' and the outer plate 12' of the door 10' to be painted. The support portion 120 is used to be clamped on the B-pillar 20' or the C-pillar. The support portion 120 has a support wall 120a. When the support portion 120 is clamped on the B-pillar 20', the support wall 120a is located between the B-pillar 20' and the A-pillar. When the support portion 120 is clamped on the C-pillar, the support wall 120a is located between the C-pillar and the B-pillar 20'. The support wall 120a is used to abut the limiting portion 110 when the second limiting end 110b is separated from the vehicle door 10' to be painted.

[0045] The door painting limiting tool 10 provided in the embodiment of the present disclosure includes a limiting portion 110 and a supporting portion 120, wherein the limiting portion 110 can be connected between the B-pillar 20' of the vehicle body to be painted and the front door, or between the C-pillar and the rear door of the vehicle body to be painted in actual application, so that the door 10' to be painted and the B-pillar 20' or the C-pillar can be structurally connected through the limiting portion 110, thereby limiting the opening and closing movement of the door 10' to be painted, so as to constrain the door 10' to be painted during the painting process. The position of the vehicle door 10' can reduce the quality problems such as paint scratches on the vehicle door 10' to be painted, and the first limiting end 110a of the limiting part 110 can be connected to the B-pillar 20' or C-pillar of the vehicle body to be painted by plugging, and the second limiting end 110b can also be connected to the vehicle door 10' to be painted by plugging, thereby improving the convenience of installation and disassembly of the limiting part 110, facilitating the operator to quickly install or disassemble the limiting part 110, and helping to improve the operational efficiency of anti-opening limiting of the vehicle door.

[0046] In practical applications, the support portion 120 can be arranged on the B-pillar 20' or C-pillar of the vehicle body to be painted, and the support wall 120a of the support portion 120 can be used to abut and support the limit portion 110 when the second limit end 110b is separated from the vehicle door 10' to be painted, so that when the anti-opening limit of the vehicle door is released, the support portion 120 can maintain a high position stability, prevent the limit portion 110 from being displaced significantly relative to the vehicle body, and reduce the possibility of the limit portion 110 hitting the vehicle body; and, because when the support portion 120 is clamped on the B-pillar 20', the support wall 120a is located at the B Between the column 20' and the A-pillar, or when the support part 120 is clamped on the C-pillar, the support wall 120a is located between the C-pillar and the B-pillar 20', so that when the support part 120 abuts against the limiting wall, the limiting part 110 and at least part of the supporting part 120 can be located in an area that is easily observed by the operator, which can facilitate the operator to find and operate the door painting limiting tool 10, improve the ease of use of the door painting limiting tool 10, and reduce the probability of the operator forgetting to remove the door painting limiting tool 10 after the painting is completed, which is beneficial to provide guarantee for the smooth execution of subsequent processing of the vehicle.

[0047] It can be understood that the vehicle body to be painted may include the aforementioned B-pillar 20', C-pillar and the aforementioned door 10' to be painted, the door 10' to be painted includes an inner panel 11' and an outer panel 12', the inner panel 11' and the outer panel 12' form the aforementioned inter-panel gap 101', and the B-pillar 20' and the C-pillar are respectively formed with at least one first mounting hole 201' and at least one second mounting hole. Figure 2 As shown, in the case where the vehicle door 10' to be painted is the front door of the vehicle body to be painted, if the vehicle door 10' to be painted needs to be limited, the first limiting end 110a of the aforementioned limiting portion 110 can be inserted into the first mounting hole 201' of the aforementioned B-pillar 20', and the second limiting end 110b can be inserted into the inter-plate gap 101' of the vehicle door 10' to be painted; accordingly, in the case where the vehicle door 10' to be painted is the rear door of the vehicle body to be painted, if the vehicle door 10' to be painted needs to be limited, the first limiting end 110a of the aforementioned limiting portion 110 can be inserted into the second mounting hole of the aforementioned C-pillar, and the second limiting end 110b can be inserted into the inter-plate gap 101' of the vehicle door 10' to be painted.

[0048] It is understandable that if Figure 3As shown, during the painting operation, if it is necessary to release the anti-opening limit of the vehicle door 10' to be painted, the aforementioned second limit end 110b can be taken out of the aforementioned inter-plate gap 101' to separate the second limit end 110b from the vehicle door 10' to be painted, and the support portion 120 can be snapped onto the B-pillar 20' or C-pillar of the vehicle body. Accordingly, the matching relationship between the first limit end 110a and the B-pillar 20' or C-pillar can be maintained, and the limit portion 110 is abutted against the support wall 120a of the support portion 120, so that the support portion 120 cooperates with the B-pillar 20' or C-pillar to support and fix the limit portion 110. At the same time, based on the above-mentioned setting, when the support part 120 is clamped on the B-pillar 20' or C-pillar of the vehicle body, the support wall 120a can be arranged corresponding to the door area of ​​the vehicle body, so that when the door is open, it is convenient for the operator to find the aforementioned limit part 110 and the aforementioned support part 120, or when the door is closed, it is convenient for the operator to find the aforementioned limit part 110 and the aforementioned support part 120 through the window of the door, and then it is convenient for the operator to find and operate the door painting limit tooling 10, thereby improving the convenience of using the door painting limit tooling 10, reducing the probability of the operator forgetting to remove the door painting limit tooling 10 after painting is completed, and is conducive to providing guarantee for the smooth execution of subsequent processing of the vehicle.

[0049] It can be understood that the door painting limiting tool 10 has a first working state and a second working state. Figure 2 As shown, in the first working state, the first limiting end 110a of the limiting portion 110 is inserted into the aforementioned first mounting hole 201' or the aforementioned second mounting hole, and the second limiting end 110b is inserted into the aforementioned inter-plate gap 101'; Figure 3 As shown, in the second working state, the first limiting end 110a of the limiting portion 110 is inserted into the first mounting hole 201' or the second mounting hole, the second limiting end 110b is separated from the door 10' to be painted, and the limiting portion 110 abuts against the supporting wall 120a.

[0050] It can be understood that, in actual applications, the aforementioned first limit end 110a and the aforementioned limit portion 110 can be used to be set on the same pillar of the vehicle body to be painted, that is, when the first limit end 110a is inserted into the first mounting hole 201' of the B-pillar 20', the limit portion 110 can be snapped onto the B-pillar 20' where the aforementioned first mounting hole 201' is located, or when the first limit end 110a is inserted into the second mounting hole of the C-pillar, the limit portion 110 can be snapped onto the C-pillar where the aforementioned second mounting hole is located, thereby narrowing the distribution range of the door painting limit tooling 10 on the vehicle body, which is beneficial to reduce the obstruction of the vehicle body surface by the limit tooling.

[0051] It is understandable that by arranging the support portion 120 to be suitable for clamping with the B-pillar 20 ′ or the C-pillar, the disassembly and assembly convenience of the support portion 120 can be improved, thereby further improving the use convenience of the door painting limiting tool 10 .

[0052] like Figures 1 to 3 As shown, in some examples, the limiting portion 110 includes: a first limiting rod 111, having a first limiting end 110a; a second limiting rod 112, having a second limiting end 110b; a first connecting rod 113, the two ends of which are respectively connected to the first limiting rod 111 and the second limiting rod 112; a third limiting rod 114, which is arranged on the first limiting rod 111, and the radial length of the third limiting rod 114 on the first limiting rod 111 is greater than the diameter of the first mounting hole 201' and the diameter of the second mounting hole.

[0053] In this technical solution, the limiting portion 110 may include the aforementioned first limiting rod 111, the second limiting rod 112, the first connecting rod 113 and the third limiting rod 114; based on the aforementioned arrangement, the limiting portion 110 may be aligned with the front-painted door 10' through the first limiting rod 111, and with the B-pillar 20' or the C-pillar through the second limiting rod 112, and the first limiting rod 111 and the second limiting rod 112 may be connected through the first connecting rod 113, thereby ensuring the anti-opening limiting effect on the door; at the same time, the third limiting rod 114 may be arranged so that the length of the third limiting rod 114 in the radial direction of the second limiting rod 112 is greater than the diameter of the first mounting hole 201' and the diameter of the second mounting hole 201'. The diameter of the hole, that is, the diameter of the first mounting hole 201' and the diameter of the second mounting hole are both smaller than the radial length of the third limiting rod 114 of the second limiting rod 112. Therefore, when the second limiting rod 112 is inserted to a certain depth position in the aforementioned first mounting hole 201' or the second mounting hole, the limiting portion 110 can use the third limiting rod 114 to abut against the corresponding B-pillar 20' or C-pillar to prevent the second limiting rod 112 from being inserted too deep, which is beneficial to improving the position stability of the limiting portion 110, further ensuring the limiting effect on the vehicle door 10' to be painted, and helping to reduce the risk of the limiting portion 110 colliding with the vehicle body.

[0054] It is understandable that if Figure 1 As shown, along the extension direction of the first limiting rod 111, a gap is formed between the third limiting rod 114 and the first limiting end 110a. The certain depth is positively correlated with the length of the gap. The length of the gap can be set according to actual needs and is not limited too much here.

[0055] It can be understood that the diameter of the first limiting rod 111 is smaller than the diameter of the first mounting hole 201 ′ and the diameter of the second mounting hole.

[0056] It is understandable that if Figure 1As shown, the extension directions of the first limiting rod 111, the second limiting rod 112, the third limiting rod 114 and the first connecting rod 113 may be different, and may be specifically set according to actual needs, and no excessive restrictions are made here.

[0057] like Figure 1 As shown, in some feasible examples, the aforementioned first limiting rod 111 can be a bent rod, so that when the first limiting rod 111 is inserted into the aforementioned first mounting hole 201' or the second mounting hole, the first limiting rod 111 can be conveniently hooked on the corresponding B-pillar 20' or C-pillar, which is beneficial to improving the installation stability of the first limiting rod 111.

[0058] like Figures 1 to 3 As shown, in some examples, the limiting portion 110 further includes: a limiting plate 115, which is disposed on the first connecting rod 113, and the limiting plate 115 forms a first card slot 115a, and the first card slot 115a is used to be connected to the first door stop 21' of the B-pillar 20' or the second door stop of the C-pillar.

[0059] In this technical solution, the limiting portion 110 may also include the aforementioned limiting plate 115; based on the aforementioned setting, the limiting portion 110 may further be clamped to the B-pillar 20' or the C-pillar through the limiting plate 115. It can be understood that the limiting plate 115 and the first limiting end 110a are used to connect to the door stop of the same pillar of the vehicle body to be painted, thereby further improving the connection reliability between the limiting portion 110 and the vehicle body, enhancing the anti-opening limiting effect of the door, and reducing the risk of movement of the limiting portion 110 relative to the vehicle body, which is beneficial to provide further guarantee for the painting quality.

[0060] It can be understood that, in the aforementioned second working state, based on the arrangement of the aforementioned limiting plate 115 , the position stability of the limiting portion 110 can also be enhanced.

[0061] like Figures 1 to 3 As shown, in some examples, the limiting portion 110 also includes: a fourth limiting rod 116, which is arranged on the first connecting rod 113, and the extension direction of the fourth limiting rod 116 intersects with the extension direction of the first connecting rod 113; wherein, when the first limiting end 110a is inserted in the first mounting hole 201' and the second limiting end 110b is inserted in the inter-plate gap 101', the fourth limiting rod 116 abuts against the B-pillar 20' to limit the first connecting rod 113 from rotating around the length direction of the vehicle body to be painted; when the first limiting end 110a is inserted in the second mounting hole and the second limiting end 110b is inserted in the inter-plate gap 101', the fourth limiting rod 116 abuts against the C-pillar to limit the first connecting rod 113 from rotating around the length direction of the vehicle body to be painted.

[0062] In this technical solution, the limiting portion 110 may further include the aforementioned fourth limiting rod 116; based on the aforementioned arrangement, in the case where the vehicle door 10' to be painted is the front door of the vehicle body to be painted, if the vehicle door 10' to be painted needs to be limited, the first limiting end 110a of the aforementioned limiting portion 110 may be inserted into the first mounting hole 201' of the aforementioned B-pillar 20', and the second limiting end 110b may be inserted into the inter-plate gap 101' of the vehicle door 10' to be painted. Accordingly, the aforementioned fourth limiting rod 116 may be used to abut the aforementioned B-pillar 20', thereby constraining the first connecting rod 113 from rotating in the length direction of the vehicle body to be painted, thereby preventing the first connecting rod 113 from rotating in a large amount in the aforementioned direction, which is beneficial to ensuring that the first limiting rod 111 and the second limiting rod 113 are in a stable state. 2, thereby further enhancing the position stability of the vehicle door; in the case that the vehicle door 10' to be painted is the rear door of the vehicle body to be painted, if the vehicle door 10' to be painted needs to be limited, the first limiting end 110a of the aforementioned limiting portion 110 can be inserted into the second mounting hole of the aforementioned C-pillar, and the second limiting end 110b can be inserted into the inter-plate gap 101' of the vehicle door 10' to be painted. Accordingly, the aforementioned fourth limiting rod 116 can be used to abut the aforementioned C-pillar, thereby restricting the first connecting rod 113 from rotating in the length direction of the vehicle body to be painted, avoiding the first connecting rod 113 from rotating a large amount in the aforementioned direction, which is beneficial to ensuring the position stability of the first limiting rod 111 and the second limiting rod 112, thereby further enhancing the limiting effect of the vehicle door.

[0063] It can be understood that the length direction of the aforementioned vehicle body to be painted is also the arrangement direction of the aforementioned A-pillar, B-pillar 20 ′ and C-pillar.

[0064] For example, Figure 1 As shown, the extension direction of the fourth limiting rod 116 is perpendicular to the extension direction of the first connecting rod 113 .

[0065] like Figure 1 As shown, in some examples, the first limiting rod 111 and the second limiting rod 112 are both mirror-symmetrical structures with respect to the axial section of the first connecting rod 113 .

[0066] In this technical solution, the first limit rod 111 and the second limit rod 112 can be set to be a mirror-symmetrical structure with respect to the axial section of the first connecting rod 113; based on the above-mentioned setting, the versatility of the limit part 110 can be improved, so that the limit part 110 can be suitable for the anti-opening limit of the left door and the right door of the vehicle body, thereby improving the versatility of the limit part 110, reducing the number of limit tooling used, and reducing the use cost of the limit tooling.

[0067] It can be understood that the aforementioned axial section of the first connecting rod 113 refers to the section passing through the axis of the first connecting rod 113. The first limiting rod 111 and the second limiting rod 112 are both in a mirror-symmetric structure with respect to the axial section of the first connecting rod 113, which means that the first limiting rod 111 is in a mirror-symmetric structure with respect to the axial section of the first connecting rod 113, and the second limiting rod 112 is in a mirror-symmetric structure with respect to the axial section of the first connecting rod 113.

[0068] In some feasible examples, the limiting portion 110 has a mirror-symmetrical structure with respect to the axial cross section of the first connecting rod 113 , thereby further improving the symmetry of the overall structure of the limiting portion 110 .

[0069] like Figure 3 As shown, in some examples, along the extension direction of the second limiting rod 112, the first connecting rod 113 is connected to the middle part of the second limiting rod 112, and both ends of the second limiting rod 112 are second limiting ends 110b, and the second limiting rod 112 includes a bent rod segment 112a located between the first connecting rod 113 and the second limiting end 110b; wherein, one second limiting end 110b of the second limiting rod 112 is used to be inserted into the gap 101' between the plates, and the other second limiting end 110b and at least one bent rod segment 112a are used to be arranged outside the gap 101' between the plates.

[0070] In this technical solution, the second limiting rod 112 can have the two aforementioned second limiting ends 110b, and the second limiting rod 112 includes a bent rod segment 112a located between the first connecting rod 113 and the second limiting end 110b, and each second limiting end 110b has at least one bent rod segment 112a between the first connecting rod 113. When the painted vehicle door 10' is limited to prevent opening, one of the second limiting ends 110b can be inserted in the inter-plate gap 101', and the other second limiting end 110b and at least one bent rod segment 112a can be arranged outside the inter-plate gap 101', so that the operator can adjust the position of the limiting part 110 by grabbing the bent rod segment 112a outside the inter-plate gap 101', so as to insert or remove the limiting part 110 from the inter-plate gap 101', which is beneficial to further improve the convenience of use of the limiting part 110 and help reduce the risk of slipping when the operator grabs the limiting part 110.

[0071] like Figure 1 As shown, in the case where the first connecting rod 113 is a bent rod, the limiting portion 110 may further include a reinforcing rib, which is disposed at the bent position of the first connecting rod 113 to enhance the structural rigidity of the first connecting rod 113 .

[0072] In some examples, the support portion 120 includes: a substrate 121, the substrate 121 is formed with a second slot 121a, the second slot 121a is used to be connected to the first door stop 21' of the B-pillar 20' or the second door stop of the C-pillar; a support rod 122, a substrate 121 at one end of the support rod 122, and a support wall 120a is formed on the support rod 122; a fifth limiting rod 123, connected to the other end of the support rod 122, the extension direction of the fifth limiting rod 123 is different from the extension direction of the support rod 122, and the fifth limiting rod 123 is used to abut the limiting portion 110; wherein, when the second slot 121a is connected to the first door stop 21' or the second door stop, the support rod 122 is located in the cab, and a gap is formed between the fifth limiting rod 123 and the door 10' to be painted.

[0073] In this technical solution, the support portion 120 may include the aforementioned base plate 121, the support rod 122 and the fifth limiting rod 123; based on the aforementioned arrangement, the support portion 120 can use the base plate 121 to clamp the B-pillar 20' or C-pillar of the vehicle body to be painted, so as to fix the position of the support portion 120. Accordingly, when the anti-opening limit of the door 10' to be painted is released, the support rod 122 can be used to abut the support limiting portion 110 to improve the position stability of the limiting portion 110, and the limiting portion 110 can be located at the driving position. Indoors, so as to form a gap between the limiting part 110 and the vehicle door 10' to be painted, which is beneficial to prevent the limiting part 110 from contacting the vehicle door 10' to be painted, thereby providing protection for the painting quality; at the same time, the supporting part 120 can use the fifth limiting rod 123 to constrain the position of the limiting part 110 on the supporting rod 122, thereby preventing the limiting part 110 from separating from the supporting rod 122, reducing the risk of a large displacement of the limiting rod relative to the vehicle body, and avoiding the support rod 122 from colliding with the vehicle body, which is beneficial to further improve the reliability of the vehicle door painting limiting tooling 10.

[0074] It can be understood that the aforementioned support wall 120a can be the outer peripheral wall of the aforementioned support.

[0075] In some feasible examples, when the second slot 121a is used to be connected to the first door stop 21' or the second door stop, the support rod 122 extends in a direction away from the vehicle body door opening, and the aforementioned fifth limiting rod 123 is located at one end of the support rod 122 away from the vehicle body door opening, so that when the limiting portion 110 abuts against the fifth limiting rod 123, the distance between the limiting portion 110 and the vehicle door can be further increased.

[0076] like Figure 3As shown, in some examples, when the second slot 121a is used to be connected to the first door stop 21' or the second door stop, the support wall 120a is arranged inclined relative to the height direction of the vehicle body, and the position height of the support wall 120a close to one end of the fifth limit rod 123 is lower than the position height of the support wall 120a away from the end of the fifth limit rod 123.

[0077] In this technical solution, when the second slot 121a is used to be connected to the first door stop 21' or the second door stop, the support wall 120a can be arranged to be inclined relative to the height direction of the vehicle body, so that the position height of the end of the support wall 120a close to the fifth limit rod 123 is lower than the position height of the end of the support wall 120a away from the fifth limit rod 123; based on the above-mentioned arrangement, the fifth limit rod 123 can be made to correspond to the end of the support wall 120a where the position height is the lowest, so that when the limiting portion 110 abuts against the support wall 120a, the limiting portion 110 is easy to slide along the extension direction of the support wall 120a under the action of gravity, toward the position of the fifth limit rod 123 until it abuts against the fifth limit rod 123, so that under the constraints of the support rod 122 and the fifth limit rod 123, the limiting portion 110 can have a higher position stability, and it is beneficial to prevent the limiting portion 110 from contacting the vehicle door 10' to be painted.

[0078] like Figures 1 to 3 As shown, in some examples, the support portion 120 also includes: a second connecting rod 124, connected between the support rod 122 and the substrate 121, and the extension direction of the second connecting rod 124 is different from the extension direction of the support rod 122; a reinforcing rod 125, connected between the second connecting rod 124 and the support rod 122.

[0079] In this technical solution, the support portion 120 may also include the aforementioned second connecting rod 124 and the reinforcing rod 125; based on the aforementioned arrangement, on the one hand, it is possible to form a larger position difference between the support rod 122 and the base plate 121, thereby facilitating the support rod 122 to adapt to the position of the limiting portion 110, which is beneficial to improving the convenience of placing the limiting portion 110 on the support wall 120a; on the other hand, it is possible to extend the support rod 122 into the cab through the door stop, thereby allowing the support rod 122 to be located in the cab, so that a gap is formed between the support rod 122 and the limiting portion 110 supported by it and the door, which is beneficial to preventing the limiting portion 110 from contacting the door 10' to be painted; on the other hand, the reinforcing rod 125 can be used to enhance the position stability and structural rigidity of the support rod 122, thereby providing a guarantee for the support rod 122 to stably support the limiting portion 110.

[0080] It can be understood that, in practical applications, the second connecting rod 124 is arranged to extend in a direction close to the limiting portion 110 .

[0081] like Figures 1 to 3 As shown, in some examples, the support portion 120 further includes: a sixth limiting rod 126, one end of which is connected to the base plate 121, and the other end is used to be inserted into the third mounting hole 202' of the B-pillar 20' or the fourth mounting hole of the C-pillar.

[0082] In this technical solution, the support portion 120 may also include the aforementioned sixth limit rod 126; based on the aforementioned setting, the support portion 120 may be further connected to the B-pillar 20' or the C-pillar through the sixth limit rod 126. It can be understood that the sixth limit rod 126 and the base plate 121 are used to be connected to the same pillar of the vehicle body to be painted, thereby further improving the connection reliability between the support portion 120 and the vehicle body, enhancing the supporting effect of the limit portion 110, and reducing the risk of the limit portion 110 moving relative to the vehicle body, which is beneficial to provide further guarantee for the painting quality.

[0083] It can be understood that the third mounting hole 202 ′ is different from the first mounting hole 201 ′, and the fourth mounting hole is different from the second mounting hole.

[0084] like Figure 1 As shown, in some feasible examples, the aforementioned sixth limiting rod 126 can be a bent rod, so that when the sixth limiting rod 126 is inserted into the aforementioned third mounting hole 202' or the fourth mounting hole, the sixth limiting rod 126 can be conveniently hooked on the corresponding B-pillar 20' or C-pillar, which is beneficial to improving the installation stability of the sixth limiting rod 126.

[0085] like Figure 1 and Figure 3 As shown, in some feasible examples, the substrate 121 is formed with a cut-angle structure 121b on one side close to the vehicle door 10' to be painted, so that the substrate 121 avoids the vehicle door 10' to be painted and prevents contact between the substrate 121 and the vehicle door 10' to be painted.

[0086] In some feasible examples, the length of the groove wall of the second groove 121a close to the vehicle door 10' to be painted is shorter than the length of the groove wall of the second groove 121a away from the vehicle door 10' to be painted, so that a gap with a width greater than or equal to 5 mm can be formed between the substrate 121 and the vehicle door 10' to be painted, thereby allowing the substrate 121 to further avoid the vehicle door 10' to be painted.
