Description

Technical Field

[0001] This disclosure relates to the field of vehicle painting technology, and in particular to a door painting limiting tool. Background Technology

[0002] Before painting, frameless car bodies require anti-opening limiters to prevent the doors from opening automatically during painting processes, thus avoiding defects such as door damage. However, existing anti-opening limiters often require cumbersome installation, making them difficult and time-consuming to install and remove, which hinders continuous production and efficiency. Summary of the Invention

[0003] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, a door painting limiting fixture is proposed according to an embodiment of the present disclosure, comprising:

[0005] The limiting part has a first limiting end and a second limiting end. The first limiting end is used to be inserted into the first mounting hole of the B-pillar or the second mounting hole of the C-pillar. The second limiting end is used to be inserted into the gap between the panels of the door to be painted. The gap between the panels is the gap between the inner panel and the outer panel of the door to be painted.

[0006] The support part is used to be snapped into the B-pillar or C-pillar. The support part has a support wall. When the support part is snapped into the B-pillar, the support wall is located between the B-pillar and the A-pillar. When the support part is snapped into the C-pillar, the support wall is located between the C-pillar and the B-pillar.

[0007] The support wall is used to abut against the limiting part when the second limiting end is separated from the door to be painted.

[0008] In one feasible implementation, the limiting part includes:

[0009] The first limiting rod has a first limiting end;

[0010] The second limiting rod has a second limiting end;

[0011] The first connecting rod has its two ends connected to the first limiting rod and the second limiting rod, respectively.

[0012] The third limiting rod is set on the first limiting rod, and the length of the third limiting rod in the radial direction of the first limiting rod is greater than the diameter of the first mounting hole and the diameter of the second mounting hole.

[0013] In one feasible implementation, the limiting part further includes:

[0014] A limiting plate is provided on the first connecting rod. The limiting plate has a first slot, which is used to engage with the first door stop of the B-pillar or the second door stop of the C-pillar.

[0015] In one feasible implementation, the limiting part further includes:

[0016] A fourth limiting rod is provided on the first connecting rod, and the extension direction of the fourth limiting rod intersects with the extension direction of the first connecting rod;

[0017] Specifically, when the first limiting end is inserted into the first mounting hole and the second limiting end is inserted into the gap between the panels, the fourth limiting rod abuts against the B-pillar to restrict the first connecting rod from rotating around the length direction of the vehicle body to be painted; when the first limiting end is inserted into the second mounting hole and the second limiting end is inserted into the gap between the panels, the fourth limiting rod abuts against the C-pillar to restrict the first connecting rod from rotating around the length direction of the vehicle body to be painted.

[0018] In one feasible implementation, both the first limiting rod and the second limiting rod are mirror-symmetrical about the axial section of the first connecting rod.

[0019] In one feasible implementation, along the extension direction of the second limiting rod, the first connecting rod is connected to the middle of the second limiting rod, both ends of the second limiting rod are second limiting ends, and the second limiting rod includes a bent rod segment located between the first connecting rod and the second limiting end;

[0020] Among them, one second limiting end of the second limiting rod is used to be inserted into the gap between the plates, and the other second limiting end and at least one bent rod segment are used to be arranged outside the gap between the plates.

[0021] In one feasible implementation, the support portion includes:

[0022] The substrate has a second slot for engaging with the first door stop of the B-pillar or the second door stop of the C-pillar.

[0023] Support rod, base plate at one end of support rod, support wall formed on support rod;

[0024] The fifth limiting rod is connected to the other end of the support rod. The extension direction of the fifth limiting rod is different from that of the support rod. The fifth limiting rod is used to abut against the limiting part.

[0025] When the second slot is engaged with the first or second door stop, the support rod is located inside the driver's cab, and there is a gap between the fifth limit rod and the door to be painted.

[0026] In one feasible implementation, when the second slot is used to engage with the first door stop or the second door stop, the support wall is arranged at an angle relative to the height of the vehicle body to be painted, and the height of the end of the support wall near the fifth limit bar is lower than the height of the end of the support wall away from the fifth limit bar.

[0027] In one feasible implementation, the support portion further includes:

[0028] The second connecting rod is connected between the support rod and the base plate, and the extension direction of the second connecting rod is different from the extension direction of the support rod.

[0029] A reinforcing rod connects the second connecting rod and the support rod.

[0030] In one feasible implementation, the support portion further includes:

[0031] The sixth limiting rod has one end connected to the base plate and the other end used to be inserted into the third mounting hole of the B-pillar or the fourth mounting hole of the C-pillar.

[0032] Compared with the prior art, this disclosure has at least the following beneficial effects: The door painting limiting fixture provided in the embodiments of this disclosure includes a limiting part and a supporting part. In practical applications, the limiting part can be connected between the B-pillar of the vehicle body to be painted and the front door, or between the C-pillar of the vehicle body to be painted and the rear door. This allows the door to be painted to be structurally connected to the B-pillar or C-pillar through the limiting part, thereby restricting the opening and closing movement of the door to be painted. This helps to constrain the position of the door during the painting process, reducing quality problems such as paint scratches on the door. Furthermore, the first limiting end of the limiting part can be connected to the B-pillar or C-pillar of the vehicle body to be painted via a plug-in connection, and the second limiting end can also be connected to the door to be painted via a plug-in connection, thereby improving the limiting effect. The ease of installation and removal of the limiting part facilitates quick installation or removal by operators, improving the efficiency of door anti-opening limiting operations. In practical applications, the support part can be installed on the B-pillar or C-pillar of the vehicle body to be painted. The support wall of the support part can be used to abut and support the limiting part when the second limiting end is separated from the door to be painted. This ensures that the support part maintains high positional stability when the door anti-opening limiting is released, preventing large displacement of the limiting part relative to the vehicle body, reducing the possibility of the limiting part hitting the vehicle body, and ensuring that at least part of the limiting part and the support part are in an area easily observed by operators. This facilitates the discovery and operation of the door painting limiting fixture, improving the ease of use of the door painting limiting fixture. Attached Figure Description

[0043] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0044] like Figures 1 to 3As shown, according to an embodiment of this disclosure, a door painting limiting fixture 10 is proposed, including: a limiting part 110 having a first limiting end 110a and a second limiting end 110b. The first limiting end 110a is used to be inserted into a first mounting hole 201' of the B-pillar 20' or a second mounting hole of the C-pillar. The second limiting end 110b is used to be inserted into the inter-panel gap 101' of the door 10' to be painted. The inter-panel gap 101' is the distance between the inner panel 11' and the outer panel 12' of the door 10' to be painted. The support portion 120 is used to engage with the B-pillar 20' or the C-pillar. The support portion 120 has a support wall 120a. When the support portion 120 is engaged with 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 engaged with 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 against the limiting portion 110 when the second limiting end 110b is separated from the door 10' to be painted.

[0045] The door painting limiting fixture 10 provided in this embodiment includes a limiting part 110 and a supporting part 120. In practical applications, the limiting part 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 of the vehicle body to be painted and the rear door. This allows the door 10' to be painted to be structurally connected to the B-pillar 20' or the C-pillar through the limiting part 110, thereby restricting the opening and closing movement of the door 10' to be painted, thus constraining the door to be painted during the painting process. The position of the door 10' reduces the risk of paint damage and other quality issues. Furthermore, 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 via a plug-in connection, and the second limiting end 110b can also be connected to the door 10' to be painted via a plug-in connection. This improves the ease of installation and removal of the limiting part 110, making it easier for operators to quickly install or remove the limiting part 110, and thus improving the efficiency of the door anti-opening limiting operation.

[0046] In practical applications, the support portion 120 can be installed on the B-pillar 20' or C-pillar of the vehicle body to be painted. The support wall 120a of the support portion 120 can abut against and support the limiting portion 110 when the second limiting end 110b is separated from the door 10' to be painted. This ensures that the support portion 120 maintains high positional stability when the anti-opening limit on the door is released, preventing large displacement of the limiting portion 110 relative to the vehicle body and reducing the possibility of the limiting portion 110 hitting the vehicle body. Furthermore, since the support wall 120a is located at the B-pillar 20' when the support portion 120 is engaged with the B-pillar 20', the support wall 120a is positioned at the B-pillar 20'. Between pillar 20' and pillar A, or when support 120 is engaged with pillar C, support wall 120a is located between pillar C and pillar B 20'. Thus, when support 120 abuts against the limiting wall, at least part of limiting part 110 and support part 120 are in an area easily observed by the operator. This makes it easier for the operator to find and operate the door painting limiting fixture 10, improves the ease of use of the door painting limiting fixture 10, reduces the probability of the operator forgetting to remove the door painting limiting fixture 10 after painting, and helps to ensure the smooth execution of subsequent vehicle processing.

[0047] It is 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', with the aforementioned inter-panel gap 101' formed between the inner panel 11' and the outer panel 12'. The B-pillar 20' and C-pillar respectively have at least one first mounting hole 201' and at least one second mounting hole. Figure 2 As shown, when the door 10' to be painted is the front door of the vehicle body to be painted, if it is necessary to limit the door 10' to be painted, the first limiting end 110a of the aforementioned limiting part 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 panel gap 101' of the door 10' to be painted; correspondingly, when the door 10' to be painted is the rear door of the vehicle body to be painted, if it is necessary to limit the door 10' to be painted, the first limiting end 110a of the aforementioned limiting part 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 panel gap 101' of the door 10' to be painted.

[0048] It is understandable that, such as Figure 3As shown, during the painting process, if it is necessary to release the anti-opening limit of the door 10' to be painted, the aforementioned second limiting end 110b can be removed from the aforementioned inter-panel gap 101' so that the second limiting end 110b is separated from the door 10' to be painted. The support part 120 can be snapped onto the B-pillar 20' or C-pillar of the vehicle body. Correspondingly, the cooperation relationship between the first limiting end 110a and the B-pillar 20' or C-pillar can be maintained, and the limiting part 110 is abutted against the support wall 120a of the support part 120, so that the support part 120 cooperates with the B-pillar 20' or C-pillar to support and fix the limiting part 110. Meanwhile, based on the aforementioned configuration, when the support part 120 is attached to 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. This makes it easier for operators to find the aforementioned limiting part 110 and the aforementioned support part 120 when the door is open, or to find the aforementioned limiting part 110 and the aforementioned support part 120 through the door window when the door is closed. This makes it easier for operators to find and operate the door painting limiting fixture 10, improving the ease of use of the door painting limiting fixture 10 and reducing the probability that operators will forget to remove the door painting limiting fixture 10 after painting. This is beneficial to ensuring the smooth execution of subsequent vehicle processing.

[0049] It is understandable that the door painting limiting fixture 10 has a first working state and a second working state. For example... Figure 2 As shown, in the first working state, the first limiting end 110a of the limiting part 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'; as Figure 3 As shown, in the second working state, the first limiting end 110a of the limiting part 110 is inserted into the aforementioned first mounting hole 201' or the aforementioned second mounting hole, the second limiting end 110b is separated from the door 10' to be painted, and the limiting part 110 abuts against the aforementioned support wall 120a.

[0050] It is understandable that, in practical applications, the aforementioned first limiting end 110a and the aforementioned limiting part 110 can be used to set on the same pillar of the vehicle body to be painted. That is, when the first limiting end 110a is inserted into the first mounting hole 201' of the B-pillar 20', the limiting part 110 can be engaged with the B-pillar 20' where the aforementioned first mounting hole 201' is located. Or, when the first limiting end 110a is inserted into the second mounting hole of the C-pillar, the limiting part 110 can be engaged with the C-pillar where the aforementioned second mounting hole is located. This can reduce the distribution range of the door painting limiting fixture 10 on the vehicle body and help reduce the obstruction of the vehicle body surface by the limiting fixture.

[0051] It is understandable that by setting the support part 120 to be compatible with the B-pillar 20' or C-pillar, the ease of disassembly and assembly of the support part 120 can be improved, thereby further enhancing the ease of use of the door painting limit tool 10.

[0052] like Figures 1 to 3 As shown, in some examples, the limiting part 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; and a third limiting rod 114 disposed on the first limiting rod 111, wherein the length of the third limiting rod 114 in the radial direction of 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 part 110 may include the aforementioned first limiting rod 111, second limiting rod 112, first connecting rod 113, and third limiting rod 114. Based on the aforementioned configuration, the limiting part 110 can connect to the receiving painted door 10' via the first limiting rod 111, connect to the B-pillar 20' or C-pillar via the second limiting rod 112, and connect the first limiting rod 111 and the second limiting rod 112 via the first connecting rod 113, thereby ensuring the anti-opening limiting effect of the door. Simultaneously, the length of the third limiting rod 114 in the radial direction of the second limiting rod 112 can be greater than the diameter of the first mounting hole 201' and 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 in the second limiting rod 112. Thus, when the second limiting rod 112 is inserted to a certain depth in the aforementioned first mounting hole 201' or second mounting hole, the limiting part 110 can use the third limiting rod 114 to abut against the corresponding B-pillar 20' or C-pillar, preventing the second limiting rod 112 from being inserted too deeply. This helps to improve the positional stability of the limiting part 110, further ensuring the limiting effect of the door 10' to be painted, and also helps to reduce the risk of the limiting part 110 hitting the vehicle body.

[0054] It is understandable that, such as Figure 1 As shown, along the extension direction of the first limiting rod 111, there is a gap between the aforementioned third limiting rod 114 and the aforementioned first limiting end 110a. The aforementioned certain depth is positively correlated with the length of the aforementioned gap. The length of the aforementioned gap can be specifically set according to actual needs, and no further limitations are made here.

[0055] It is understandable that the diameter of the aforementioned 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, such as 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 differ, and can be set according to actual needs. No further restrictions are imposed 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 second mounting hole, the first limiting rod 111 can be easily hooked onto 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 part 110 further includes a limiting plate 115 disposed on the first connecting rod 113. The limiting plate 115 has a first slot 115a, which is used to engage with 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 part 110 may further include the aforementioned limiting plate 115; based on the aforementioned configuration, the limiting part 110 can further engage with the B-pillar 20' or C-pillar via the limiting plate 115. It is 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 part 110 and the vehicle body, enhancing the anti-opening limiting effect of the door, and reducing the risk of the limiting part 110 moving relative to the vehicle body, which is conducive to providing further assurance for the painting quality.

[0060] It is understandable that, in the aforementioned second working state, the positional stability of the limiting part 110 can also be enhanced based on the aforementioned setting of the limiting plate 115.

[0061] like Figures 1 to 3 As shown, in some examples, the limiting part 110 further includes a fourth limiting rod 116 disposed on the first connecting rod 113, the extension direction of the fourth limiting rod 116 intersecting the extension direction of the first connecting rod 113; wherein, when the first limiting end 110a is inserted into the first mounting hole 201' and the second limiting end 110b is inserted into the inter-panel gap 101', the fourth limiting rod 116 abuts against the B-pillar 20' to restrict 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 into the second mounting hole and the second limiting end 110b is inserted into the inter-panel gap 101', the fourth limiting rod 116 abuts against the C-pillar to restrict 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 part 110 may further include the aforementioned fourth limiting rod 116. Based on the aforementioned configuration, when the door to be painted 10' is the front door of the vehicle body to be painted, if it is necessary to limit the door to be painted 10', the first limiting end 110a of the aforementioned limiting part 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-panel gap 101' of the door to be painted 10'. Correspondingly, the aforementioned fourth limiting rod 116 can be used to abut against the aforementioned B-pillar 20', thereby constraining the rotation of the first connecting rod 113 around the length direction of the vehicle body to be painted, preventing the first connecting rod 113 from generating a large amount of rotation in the aforementioned direction, which is beneficial to ensuring the first limiting rod 111 and the second limiting rod 116. The positional stability of the 2nd limiter further enhances the limiting effect on the door. When the door to be painted 10' is the rear door of the vehicle body to be painted, if it is necessary to limit the door to be painted 10', the first limiting end 110a of the aforementioned limiting part 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-panel gap 101' of the door to be painted 10'. Correspondingly, the aforementioned fourth limiting rod 116 can be used to abut against the aforementioned C-pillar, thereby constraining the rotation of the first connecting rod 113 around the length direction of the vehicle body to be painted, avoiding a large amount of rotation of the first connecting rod 113 in the aforementioned direction, which helps to ensure the positional stability of the first limiting rod 111 and the second limiting rod 112, thereby further enhancing the limiting effect on the door.

[0063] It is understandable 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, such as Figure 1 As shown, the extension direction of the aforementioned fourth limiting rod 116 is perpendicular to the extension direction of the aforementioned 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-symmetric about the axial section of the first connecting rod 113.

[0066] In this technical solution, the first limiting rod 111 and the second limiting rod 112 can be configured to have a mirror-symmetric structure about the axial section of the first connecting rod 113. Based on the aforementioned configuration, the versatility of the limiting part 110 can be improved, making the limiting part 110 suitable for the anti-opening limiting of the left and right doors of the vehicle body, thereby improving the versatility of the limiting part 110, reducing the number of limiting fixtures used, and lowering the cost of using the limiting fixtures.

[0067] It is 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 mirror-symmetric about the axial section of the first connecting rod 113, meaning that the first limiting rod 111 is mirror-symmetric about the axial section of the first connecting rod 113, and the second limiting rod 112 is mirror-symmetric about the axial section of the first connecting rod 113.

[0068] In some feasible examples, the limiting part 110 has a mirror-symmetric structure about the axial section of the first connecting rod 113, which can further improve the symmetry of the overall structure of the limiting part 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 of the second limiting rod 112, and both ends of the second limiting rod 112 are second limiting ends 110b. The second limiting rod 112 includes a bent rod segment 112a located between the first connecting rod 113 and the second limiting end 110b. One second limiting end 110b of the second limiting rod 112 is used to be inserted into the inter-plate gap 101', and the other second limiting end 110b and at least one bent rod segment 112a are used to be arranged outside the inter-plate gap 101'.

[0070] In this technical solution, the second limiting rod 112 may have two aforementioned second limiting ends 110b. The second limiting rod 112 includes a bent rod segment 112a located between the first connecting rod 113 and the second limiting end 110b. Each second limiting end 110b has at least one bent rod segment 112a between it and the first connecting rod 113. When the door 10' to be painted is locked to prevent opening, one of the second limiting ends 110b can be inserted into the gap between the panels 101', and the other second limiting end 110b and at least one bent rod segment 112a can be arranged outside the gap between the panels 101'. This makes it easier for operators to adjust the position of the limiting part 110 by grabbing the bent rod segment 112a outside the gap between the panels 101', so as to insert or remove the limiting part 110 into or out of the gap between the panels 101'. This is beneficial to further improve the ease of use of the limiting part 110 and helps to reduce the risk of slippage when operators grab the limiting part 110.

[0071] like Figure 1 As shown, when the first connecting rod 113 is a bent rod, the limiting part 110 may also include a reinforcing rib. The reinforcing rib 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 base plate 121, the base plate 121 having a second slot 121a for engaging with the first door stop 21' of the B-pillar 20' or the second door stop of the C-pillar; a support rod 122, one end of the support rod 122 being the base plate 121, and a support wall 120a being formed on the support rod 122; and a fifth limiting rod 123 connected to the other end of the support rod 122, the extension direction of the fifth limiting rod 123 being different from the extension direction of the support rod 122, and the fifth limiting rod 123 being used to abut against the limiting portion 110; wherein, when the second slot 121a is engaged with the first door stop 21' or the second door stop, the support rod 122 is located in the driver's 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 part 120 may include the aforementioned base plate 121, support rod 122, and fifth limiting rod 123. Based on the aforementioned configuration, the support part 120 can use the base plate 121 to engage with the B-pillar 20' or C-pillar of the vehicle body to be painted, thereby fixing the position of the support part 120. Correspondingly, when the anti-opening limit of the door 10' to be painted is released, the support rod 122 can abut against the support limiting part 110 to improve the positional stability of the limiting part 110 and allow the limiting part 110 to be positioned in the driver's seat. In the interior, this allows for a gap between the limiting part 110 and the door 10' to be painted, preventing the limiting part 110 from contacting the door 10' and ensuring painting quality. At the same time, the support part 120 can use the fifth limiting rod 123 to constrain the position of the limiting part 110 on the support rod 122, preventing the limiting part 110 from detaching from the support rod 122, reducing the risk of the limiting rod shifting significantly relative to the vehicle body, and preventing the support rod 122 from colliding with the vehicle body. This further improves the reliability of the door painting limiting fixture 10.

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

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

[0076] like Figure 3As shown, in some examples, when the second slot 121a is used to engage with the first door stop 21' or the second door stop, the support wall 120a is arranged at an angle relative to the height of the vehicle body, and the height of the end of the support wall 120a near the fifth limit rod 123 is lower than the height of the end of the support wall 120a away from the fifth limit rod 123.

[0077] In this technical solution, when the second slot 121a is used to engage with the first door stop 21' or the second door stop, the support wall 120a is arranged at an angle relative to the height of the vehicle body, so that the height of the end of the support wall 120a near the fifth limiting rod 123 is lower than the height of the end of the support wall 120a away from the fifth limiting rod 123. Based on the aforementioned arrangement, the fifth limiting rod 123 can be positioned at the end where the height of the support wall 120a intersects. Thus, when the limiting part 110 abuts against the support wall 120a, the limiting part 110 can easily slide along the extension direction of the support wall 120a towards the position of the fifth limiting rod 123 under the action of gravity until it abuts against the fifth limiting rod 123. Thus, under the constraint of the support rod 122 and the fifth limiting rod 123, the limiting part 110 can have high positional stability and is conducive to preventing the limiting part 110 from contacting the door 10' to be painted.

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

[0079] In this technical solution, the support part 120 may further include the aforementioned second connecting rod 124 and reinforcing rod 125. Based on the aforementioned arrangement, on the one hand, it is convenient to form a large positional difference between the support rod 122 and the substrate 121, thereby facilitating the support rod 122 to adapt to the position of the limiting part 110, which is beneficial to improving the convenience of placing the limiting part 110 on the support wall 120a; on the other hand, it is convenient for the support rod 122 to extend from the door stop into the driver's compartment, thereby placing the support rod 122 in the driver's compartment, so that a gap is formed between the support rod 122 and the limiting part 110 it supports and the door, which is beneficial to prevent the limiting part 110 from contacting the door 10' to be painted; furthermore, the reinforcing rod 125 can be used to enhance the positional stability and structural rigidity of the support rod 122, providing a guarantee for the support rod 122 to stably support the limiting part 110.

[0080] Understandably, in practical applications, the second connecting rod 124 is arranged to extend toward the limiting part 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 substrate 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 part 120 may further include the aforementioned sixth limiting rod 126; based on the aforementioned configuration, the support part 120 may be further connected to the B-pillar 20' or C-pillar via the sixth limiting rod 126. It is understood that the sixth limiting rod 126 and the base plate 121 are used to connect to the same pillar of the vehicle body to be painted, thereby further improving the connection reliability between the support part 120 and the vehicle body, enhancing the support effect on the limiting part 110, reducing the risk of the limiting part 110 moving relative to the vehicle body, and providing further assurance for the painting quality.

[0083] It is understood that the aforementioned third mounting hole 202' is different from the aforementioned first mounting hole 201', and the aforementioned fourth mounting hole is different from the aforementioned 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 fourth mounting hole, the sixth limiting rod 126 can be easily hooked onto 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 aforementioned substrate 121 has a chamfered structure 121b formed on the side of the aforementioned door 10' to be painted, so that the substrate 121 avoids the door 10' to be painted and prevents contact between the substrate 121 and the door 10' to be painted.

[0086] In some feasible examples, the length of the groove wall of the second slot 121a near the door 10' to be painted is shorter than the length of the groove wall of the second slot 121a away from the 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 door 10' to be painted, thereby enabling the substrate 121 to further avoid the door 10' to be painted.
