When an element is considered to be "disposed on" another element, it can be directly disposed on the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0048] Some embodiments of this application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0049] See Figure 1 , this embodiment provides a positioning tooling 100 for assembling a vehicle. See Figure 2 and Figure 3 , the vehicle includes a door 202, a vehicle body 201 and a hinge assembly 204. The hinge assembly 204 includes a first hinge member 2041 and a second hinge member 2042. The first hinge member 2041 is connected to the door 202, and the second hinge member 2042 is used to connect to the vehicle body 201. The second hinge member 2042 is rotatably connected to the first hinge member 2041. The hinge assembly 204 further includes a pivot 2043. The first hinge member 2041 and the second hinge member 2042 are rotatably connected by the pivot 2043.

[0050] See Figure 1 , the positioning tooling 100 includes a positioning component 10, an angle correction member 20 and a first abutting member 30. The positioning component 10 is used to position the door 202 at the assembly position. The assembly position refers to the position of the door 202 before being assembled to the vehicle body 201. After the door 202 enters the assembly position, the vehicle body 201 and the door 202 are connected by connection means such as threaded connection and welding. Specifically, the vehicle body 201 can be arranged on a workbench, and the position of the door 202 relative to the vehicle body 201 is positioned by the positioning component 10.

[0051] The first hinge member 2041 is fixedly connected to the door 202. After the door 202 enters the assembly position, the angle correction member 20 and the first abutting member 30 cooperate to position the position of the second hinge member 2042 relative to the first hinge member 2041, and then the second hinge member 2042 is connected to the vehicle body 201.

[0052] Among them, see Figure 2 and Figure 3, the angle correction member 20 and the first abutting member 30 are used to position the initial angle between the first hinge member 2041 and the second hinge member 2042. The initial angle refers to the designed included angle between the first hinge member 2041 and the second hinge member 2042 when the vehicle door 202 is in the assembled position. The angle correction member 20 includes a first correction surface P1 and a second correction surface P2 connected at a preset angle. The first correction surface P1 is used to fit the first hinge member 2041, and the second correction surface P2 is used to fit the second hinge member 2042. One end of the first abutting member 30 is used for positioning and mating with the vehicle body 201, and the other end of the first abutting member 30 is used to abut against the second hinge member 2042, so that the second hinge member 2042 remains in contact with the second correction surface P2, and the second hinge member 2042 pushes the first correction surface P1 of the angle correction member 20 to remain in contact with the first hinge member 2041. For example, there is a first included angle α between the first correction surface P1 and the second correction surface P2, and a second included angle β between the first hinge member 2041 and the second hinge member 2042. By controlling the first included angle α to be equal to the initial angle, the second included angle β can be adjusted to be equal to the initial angle.

[0053] According to the positioning tooling 100 of the present application, the vehicle door 202 is positioned by the positioning assembly 10 so that the vehicle door 202 enters the assembled position, thereby making the first hinge member 2041 relatively fixed to the vehicle body 201. Then, the angle correction member 20 is placed between the first hinge member 2041 and the second hinge member 2042. At this time, the second hinge member 2042 and the first hinge member 2041 can rotate relative to each other. The second hinge member 2042 is pushed to the positioning position by the first abutting member 30, so that the second hinge member 2042 fits the second correction surface P2, the first correction surface P1 fits the first hinge member 2041, and the included angle between the first hinge member 2041 and the second hinge member 2042 is the preset angle; then the second hinge member 2042 is fixed to the vehicle body 201. In this way, only by setting the preset angle between the first correction surface P1 and the second correction surface P2 to the initial angle of the hinge assembly 204, it can be ensured that the angle between the first hinge member 2041 and the second hinge member 2042 is substantially the same as the initial angle.

[0054] Therefore, the positioning tooling 100 of the present application can improve the correction accuracy of the initial angle between the first hinge member 2041 and the second hinge member 2042, reduce the assembly error and the rework rate. At the same time, the use method of the positioning tooling 100 is simple and easy, which can improve the assembly efficiency between the vehicle door 202 and the vehicle body 201.

[0055] In addition, due to the high accuracy of the initial angle, the hinge stress concentration or the drooping of the vehicle door 202 caused by the angle deviation can be reduced, the wear risk during long-term use can be reduced, and the smoothness of opening and closing of the vehicle door 202 and the closing texture can be further improved significantly.

[0056] Optionally, there are multiple hinge assemblies 204 and multiple angle correction members 20. Each angle correction member 20 is provided corresponding to one hinge assembly 204. There are multiple first abutting members 30. Each first abutting member 30 is provided corresponding to one hinge assembly 204.

[0057] In some embodiments, see Figure 2 The first hinge 2041 includes a first surface P3. The first correction surface P1 is configured to be in the same shape as the first surface P3. The second hinge 2042 includes a second surface P4. The second correction surface P2 is configured to be in the same shape as the second surface P4. The configuration is that the shape of the first correction surface P1 is similar to or identical to the shape of the first surface P3, and the shape of the second correction surface P2 is similar to or identical to the shape of the second surface P4, thereby improving the installation accuracy of the angle correction member 20 between the first hinge 2041 and the second hinge 2042, and further improving the positioning accuracy of the initial angle.

[0058] In some embodiments, see Figure 2 and Figure 3 , the door 202 is connected to one end of the vehicle body 201 along the first direction X. The length direction of the pivot 2043 of the hinge assembly 204 is parallel to the second direction Y. The first abutting member 30 is used to abut the second hinge member 2042 along the third direction Z. The first direction X intersects with the second direction Y, the third direction Z intersects with the first direction X, and the second direction Y intersects with the third direction Z. The door 202 can be a ground door, a sky door, or a side door. In this embodiment, the first direction X is parallel to the length direction of the vehicle, the second direction Y is parallel to the width direction of the vehicle, and the third direction Z is parallel to the height direction of the vehicle.

[0059] In some embodiments, see Figure 4 The angle correction member 20 includes a correction portion 21 and a first adjustment portion 22. The correction portion 21 defines a second correction plane P2, and the correction portion 21 is detachably connected to the second hinge 2042. The first adjustment portion 22 is detachably connected to a side of the correction portion 21 facing the first hinge 2041, and a side of the first adjustment portion 22 away from the correction portion 21 defines a first correction plane P1.

[0060] In this way, by replacing different first adjustment parts 22 , the angle between the first correction plane P1 and the second correction plane P2 can be adjusted, thereby meeting the positioning requirements of the initial angles of different hinge assemblies 204 and improving the versatility of the positioning tool 100 .

[0061] In some embodiments, see Figure 4, the first adjustment part 22 is provided with a countersunk hole K1. The countersunk hole K1 is used to accommodate a connection structure (not shown in the figure), and the connection structure is used to connect the first adjustment part 22 and the correction part 21. The countersunk hole K1 can prevent the connection structure from protruding from the first adjustment part 22, thereby avoiding interference between the connection structure and the first hinge member 2041.

[0062] In some embodiments, refer to Figure 5 , the correction part 21 is provided with a connection hole K2. The angle correction member 20 further includes a first connection part 23. The first connection part 23 is disposed in the connection hole K2. The first connection part 23 is used to connect the second hinge member 2042. In this way, the first connection part 23 can further improve the fitting accuracy between the second correction plane P2 and the second hinge member 2042. Optionally, the connection hole K2 can be a blind hole recessed from the second correction plane P2 or a through hole.

[0063] Optionally, the first connection part 23 can be configured as a magnet, and the magnet can be a permanent magnet or an electromagnet. When the second hinge member 2042 is a metal component, the magnet can take into account both connection reliability and disassembly convenience. In other embodiments, the first connection part 23 can also be a fastening component such as a screw or a pin.

[0064] In some embodiments, refer to Figures 4 to 6 , the correction part 21 is also provided with a weight reduction hole K3. The weight reduction hole K3 is spaced from the connection hole K2. The weight reduction hole K3 can reduce the weight of the angle correction member 20. In addition, the weight reduction hole K3 can also serve to avoid part of the structure of the second hinge member 2042. For example, in some embodiments (as shown in Figure 2 ), the second hinge member 2042 includes a first hinge segment 20421, a second hinge segment 20422, and a fastener (not shown in the figure). One end of the first hinge segment 20421 is rotatably connected to the first hinge member 2041 through a pivot 2043. One end of the second hinge segment 20422 is connected to the first hinge segment 20421 through a fastener. The first abutting member 30 is used to abut against the other end of the second hinge segment 20422. The second hinge segment 20422 is used to connect the vehicle body 201. When the angle correction member 20 is disposed on the second hinge member 2042, the fastener extends into the weight reduction hole K3.

[0065] In some embodiments, refer to Figure 7 and Figure 8, the positioning tooling 100 further includes a base 40 and a first elastic member 50. The first elastic member 50 elastically supports between the first abutting member 30 and the base 40. The first elastic member 50 is used to apply an elastic force to the first abutting member 30 so that the first abutting member 30 remains in abutment against the second hinge member 2042. The first abutting portion 132 can stably conduct the elastic force of the first elastic member 50 to the second hinge member 2042. Thus, after the vehicle door 202 enters the assembly position, aligning the second hinge member 2042 with the first abutting portion 132 can make the first abutting portion 132 remain in abutment against the second hinge member 2042, thereby improving the working convenience of the first abutting member 30. The first elastic member 50 can be set as an elastic structure such as a spring, a tension spring or an elastic column. In addition, by replacing the first elastic member 50 with different elastic forces, the abutting force of the first abutting member 30 against the second hinge member 2042 can be adjusted to ensure that the first abutting member 30 not only pushes the second hinge member 2042 to abut against the angle correction member 20 and the vehicle body 201, but also avoids the angle correction member 20 from damaging the first hinge member 2041, or the second hinge member 2042 from damaging the vehicle body 201.

[0066] In other embodiments, the first abutting member 30 can also be set as components such as a cylinder or an electric push rod.

[0067] Optionally, referring to Figure 8 , the first abutting member 30 includes an abutting block 31 and a guide rod 32. The guide rod 32 is slidably disposed through the base 40. The abutting block 31 is connected to one end of the guide rod 32. The first elastic member 50 is sleeved outside the guide rod 32, and both ends of the first elastic member 50 respectively abut against the abutting block 31 and the base 40.

[0068] Wherein, when the base 40 is installed on the vehicle body 201, the extending direction of the guide rod 32 is parallel to the third direction Z, thereby improving the direction accuracy of the elastic force applied by the first elastic member 50 to the first abutting member 30.

[0069] Optionally, referring to Figure 8 , the number of the guide rods 32 is multiple. The multiple guide rods 32 are arranged at intervals, and the abutting block 31 is connected to the multiple guide rods 32. Thus, the degree of freedom of movement of the abutting block 31 can be further limited, so that the abutting block 31 only has the degree of freedom of moving along the length direction of the guide rod 32.

[0070] Optionally, referring to Figure 8 , the base 40 is provided with a bearing 41. The guide rod 32 is slidably fitted in the bearing 41. Thus, the smoothness of the movement of the guide rod 32 is improved.

[0071] Optionally, referring to Figure 8The first abutting member 30 further includes an anti-slipping portion 33. The anti-slipping portion 33 is located on a side of the base 40 away from the abutting block 31. The anti-slipping portion 33 is connected to the guide rod 32. The anti-slipping portion 33 is used to prevent the guide rod 32 from slipping out of the base 40. In this way, it can be ensured that the first abutting member 30 stably pushes the second hinge member 2042 to move.

[0072] In some embodiments, see Figure 7 The positioning tool 100 also includes a limiting assembly 60. The first push member 30 is connected to the limiting assembly 60. The limiting assembly 60 is used to position and cooperate with the vehicle body 201 so that the first push member 30 pushes against the second hinge 2042. Specifically, the limiting assembly 60 is connected to the base 40, and the first push member 30 is connected to the base 40, so that the first push member 30 is connected to the limiting assembly 60. After the vehicle door 202 enters the assembly position, the installation position of the first push member 30 on the vehicle body 201 can be positioned by the limiting assembly 60, so that the position of the first push member 30 relative to the second hinge 2042 is accurate, thereby improving the movement accuracy of the first push member 30 pushing the second hinge 2042, improving the position accuracy of the second hinge 2042, the angle correction member 20 and the first hinge 2041, and then improving the positioning reliability.

[0073] Optionally, there are multiple bases 40 and multiple limiter assemblies 60. Each limiter assembly 60 is connected to a corresponding base 40. The multiple bases 40 can be distributed along the second direction Y to carry different numbers of first abutting members 30.

[0074] Alternatively, see Figure 7 The positioning tool 100 further includes a first handle 70. The first handle 70 is connected to the base 40. The first handle 70 can facilitate the operator to take and place the limiting component 60.

[0075] In some embodiments, see Figure 7 and Figure 9 The limiting assembly 60 includes a first limiting member 61, a second limiting member 62 and a third limiting member 63. The first limiting member 61 is used to position and cooperate with the vehicle body 201 along the first direction X, the second limiting member 62 is used to position and cooperate with the vehicle body 201 along the second direction Y, and the third limiting member 63 is used to position and cooperate with the vehicle body 201 along the third direction Z. The first direction X intersects with the second direction Y, the third direction Z intersects with the first direction X, and the second direction Y intersects with the third direction Z. In this way, the first limiting member 61, the second limiting member 62 and the third limiting member 63 can be positioned on the vehicle body 201 in six degrees of freedom in space, thereby ensuring the accuracy of the installation position of the first abutting member 30.

[0076] In some embodiments, see Figure 7 and Figure 9, the vehicle body 201 is provided with a mating component 205. The mating component 205 is provided with a mating hole K4. The mating component 205 includes a mating portion 2051. The first limiting member 61 includes a fixing portion 611 and a clamping portion 612. The clamping portion 612 is used to clamp the mating component 205 with the fixing portion 611 along the first direction X. The second limiting member 62 is provided with a clamping groove C1, and the extending direction of the clamping groove C1 is perpendicular to the second direction Y. The mating portion 2051 is fitted into the clamping groove C1. The third limiting member 63 is clamped to the edge of the mating component 205 near the mating hole K4 to position and mate with the first mating member 2052 along the third direction Z.

[0077] During the installation of the limiting component 60, the third limiting member 63 is passed through the mating hole K4 and clamped to the edge of the mating component 205 extending to the mating hole K4, so as to fix the position of the third limiting member 63 along the third direction Z. At the same time, the second limiting member 62 is inserted and fitted with the mating portion 2051. The mating portion 2051 can limit the second limiting member 62 in the second direction Y, so as to fix the position of the second limiting member 62 along the second direction Y. Thereafter, by clamping the mating component 205 with the clamping portion 612 and the fixing portion 611 along the first direction X, the first limiting member 61 can be limited to the mating component 205 in the first direction X. In this way, the position fixing of the limiting component 60 and the mating component 205 in the first direction X, the second direction Y and the third direction Z is realized.

[0078] Optionally, the mating component 205 includes a first mating member 2052 and a second mating member 2053. The first mating member 2052 and the second mating member 2053 are arranged on the vehicle body 201 at intervals along the first direction X. The first mating member 2052 is provided with a mating hole K4. The second mating member 2053 is provided with a mating portion 2051. Specifically, the mating component 205 can be an anti-collision beam installation member.

[0079] In some embodiments, refer to Figure 7 and Figure 9 , the first limiting member 61 further includes a handle 613. The handle 613 is rotatably connected to the fixing portion 611. One end of the clamping portion 612 is connected to the handle 613. By rotating the handle 613 relative to the fixing portion 611, the other end of the clamping portion 612 can be driven to move away from the fixing portion 611 to release the mating component 205, or the other end of the clamping portion 612 can be driven to approach the fixing portion 611 to clamp the mating component 205 along the first direction X.

[0080] In some embodiments, refer to Figure 7 and Figure 9 , the limiting component 60 includes two first limiting members 61. The two first limiting members 61 are arranged at intervals along the second direction Y. The two first limiting members 61 are respectively used to clamp two edges of the mating component 205 arranged back to back along the second direction Y.

[0081] In some embodiments, referring to Figure 7 and Figure 9 , the third limiting member 63 includes a first limiting portion 631 and a second limiting portion 632.
