[0035] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0036] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0037] In the embodiments of the present application, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°.

[0038] like Figure 1 As shown, the accessory assembly jig provided in the embodiment of the present application includes a body 1, a limiting member 4, a supporting platform 2 and a fixing member 3 arranged on the supporting platform 2.

[0039] The fixing member 3 is used to connect with the accessory and retain it on the supporting platform 2. The accessory in this case is a bumper. It is understood that the accessory can also be other vehicle accessories or accessories of other assemblies. The supporting platform 2 is hinged to the body 1. In some embodiments, the hinge axis between the supporting platform 2 and the body 1 extends horizontally. It is understood that in other embodiments, the hinge axis between the supporting platform 2 and the body 1 can also extend vertically or at an angle. These are not restrictive.

[0040] The limiting member 4 is connected to the body 1 and the supporting platform 2, and the Figures 1 to 3 As shown, the position limiter 4 is used to maintain the support platform 2 in a first position and a second position. The first and second positions allow the support platform 2 to rotate at different angles relative to the body 1. The first position can be used for bumper assembly. That is, after the position limiter 4 maintains the support platform 2 in the first position, the bumper's support angle meets the bumper assembly requirements. The second position can be used for bumper loading. That is, after the position limiter 4 maintains the support platform 2 in the second position, the bumper's joints are horizontally aligned with those of the vehicle body, allowing the bumper to be loaded by moving the body 1.

[0041] Based on the accessory assembly jig provided by the present invention, the worker places the bumper on the supporting platform 2, fixes it with the fixing part 3, and then the limiting part 4 keeps the supporting platform 2 in the first position, and then the assembly operation can be carried out. The limiting part 4 then keeps the supporting platform 2 in the second position, and the loading operation can be carried out by operating the body 1. There is no need for multiple workers to carry the bumper twice, which increases work efficiency and saves labor costs.

[0042] In addition, in the related art, when multiple workers are used to lift the bumper for mounting (attaching the bumper to the vehicle body), the increased number of workers does not improve work efficiency. Instead, it affects efficiency because the installation reference point cannot be quickly and accurately found. In addition, the bumper is not lifted steadily by humans, resulting in a large gap between the bumper and the vehicle body during the mounting process, leading to poor assembly. However, the present application stably supports the bumper through the support platform 2 and can drive the bumper to the mounting position through the body 1. This eliminates the need for multiple workers, accurately finds the reference point, and quickly installs. It also eliminates the problem of a large gap between the bumper and the vehicle body, thereby improving assembly quality.

[0043] In some embodiments, as Figure 1 As shown, the limiting member 4 includes a tightening device 41 and a limiting rope 42. The tightening device 41 is arranged on the body 1. One end of the limiting rope 42 is connected to the supporting platform 2. The tightening device 41 is connected to the limiting rope 42. The tightening device 41 is used to pull the limiting rope 42, and then tighten the supporting platform 2 through the limiting rope 42.

[0044] Under this design, when the supporting platform 2 is flipped to the first position or the second position, the position of the supporting platform 2 can be maintained through the cooperation of the tightening device 41, the limiting rope 42 and the gravity of the bumper, so that the bumper on the supporting platform 2 can perform corresponding operations.

[0045] In some embodiments, the tightening device 41 includes a coil spring and a rotating shaft. The rotating shaft is rotatably connected to the body 1. A limit rope 42 is wound around the rotating shaft. The coil spring is connected to the rotating shaft and is used to drive the rotating shaft to rotate so that the limit rope 42 is wound around the rotating shaft. In the first position, the limit rope 42 is wound around the rotating shaft to a first limit position. In the second position, the limit rope 42 is unwound from the rotating shaft to a second limit position. The first limit position refers to the maximum limit at which the limit rope 42 is wound around the rotating shaft. That is, after the limit rope 42 is wound around the rotating shaft to the maximum limit position, the limit rope 42 cannot be further wound, thereby maintaining the support platform 2 in the first position. The second limit position refers to the minimum limit at which the limit rope 42 is wound around the rotating shaft. That is, after the rotating shaft releases the limit rope 42 to the minimum limit position, the limit rope 42 cannot be further released, thereby maintaining the support platform 2 in the second position.

[0046] Under this design, the rotating shaft is driven to rotate by the winding spring to realize the winding of the limit rope 42, so that the limit rope 42 tightens the supporting platform 2, and the limit rope 42 can be wound or opened as the supporting platform 2 rotates between the first position and the second position, so as to facilitate the adjustment and maintenance of the position of the supporting platform 2.

[0047] In some embodiments, as Figure 1 As shown, the load-bearing workbench also includes a flip arm 21, which is arranged on the load-bearing platform 2, specifically on the side of the load-bearing platform 2 facing the machine body 1, and the end of the limiting rope 42 is connected to the flip arm 21. A support rod 11 is provided on the machine body 1, and when the load-bearing platform 2 rotates in the direction toward the machine body 1, the support rod 11 is used to limit the rotation range of the load-bearing platform 2. Specifically, when the flip arm 21 overlaps with the support rod 11, the load-bearing platform 2 rotates to the first position, at which time the position of the load-bearing platform 2 can be maintained by the limiting rope 42. Among them, the load-bearing platform 2 here rotates in the direction toward the machine body 1, that is, Figure 1 The middle platform 2 rotates along the direction A1.

[0048] When the support platform 2 is in the first position, the support platform 2 tilts toward the body 1, so that the support platform 2 tilts to support the bumper. At this time, the tilt angle of the support platform 2 should be such that the center of gravity of the bumper is located on the side of the body 1 at the connection point between the fixing member 3 and the bumper, so that the bumper is pressed against the support platform 2, so that the position of the bumper and the support platform 2 can be maintained by itself and / or in cooperation with the limiting rope 42. It is understandable that when the tension provided by the limiting rope 42 is large enough, or the tilt angle of the support platform 2 is sufficient to fully support the bumper, the position of the center of gravity of the bumper connected to the support member is not restricted. In addition, a flip handle can be provided on the flip arm 21 to facilitate manual operation of the flip arm 21 by the staff.

[0049] In some embodiments, a limit plate is further provided on the body 1. When the platform 2 rotates in a direction away from the body 1, the limit plate is used to limit the rotation range of the platform 2. When the bottom of the platform 2 overlaps the limit plate, the platform 2 rotates to the second position. At this time, the platform 2 can be maintained in the second position by the weight of the bumper itself. When the platform 2 is in the second position, the plane where the platform 2 is located is a horizontal plane. The platform 2 at this position rotates in a direction away from the body 1, that is, Figure 1 The middle platform 2 rotates along the direction A2.

[0050] The working principle of the limiter 4 of this design is as follows:

[0051] When not in use, no bumper is placed on the supporting platform 2. At this time, the supporting platform 2 is manually flipped toward the body 1, or the supporting platform 2 is flipped toward the body 1 under the action of the limiting rope 42 until the flip arm 21 contacts the support rod 11, and the supporting platform 2 is in the first position.

[0052] In the assembly state, the staff places the bumper on the supporting platform 2 in the first position and connects it to the bumper through the fixing part 3. At this time, the supporting platform 2 is tilted toward the body 1 (the top surface of the supporting platform 2 faces the body 1), and the center of gravity of the bumper is pressed toward the supporting platform 2. Under the action of the gravity of the supporting platform 2 and the tension of the limiting rope 42, the position of the bumper can be maintained, and the staff performs the assembly operation.

[0053] In the loading state, the operator operates the tilting arm 21 to rotate the loading platform 2. When the bottom of the loading platform 2 overlaps the limit plate, the loading platform 2 rotates to the second position. The loading operation can be carried out by operating the body 1, which is convenient. When the loading platform 2 is tilted, the tension of the limit rope 42 can slowly lower the loading platform 2, avoiding impact between components and increasing its service life.

[0054] In other embodiments, Figure 1 As shown, the tightening device 41 includes a hoisting motor, and the limiting rope 42 is wound on the reel of the hoisting motor. The hoisting motor can tighten or release the limiting rope 42 by driving the reel to rotate.

[0055] It can be seen that the design of the tightening device 41 of the present application is not limited and can be designed according to actual needs.

[0056] In some embodiments, continue with reference to Figure 1The accessory assembly jig further includes a driver 5 and a lifting frame 6. The support platform 2 is hingedly connected to the lifting frame 6, allowing the support platform 2 to flip relative to the lifting frame 6. The driver 5 is connected to the lifting frame 6 and the body 1 and is used to drive the lifting frame 6 to move in the vertical direction. The support rod 11 and the limit plate are both provided on the lifting frame 6 of the body 1.

[0057] Under this design, the driving member 5 drives the lifting frame 6 to move to change the vertical position of the supporting platform 2, thereby changing the supporting height of the supporting platform 2 for the bumper, making it convenient for the staff to select a suitable height for operation. In addition, during the loading operation, the height of the supporting platform 2 can be adjusted to make the position of the bumper relative to the vehicle body, so as to facilitate the assembly of the bumper on the vehicle body and increase the convenience of the staff's operation.

[0058] In some embodiments, combined Figure 1 and Figure 3 As shown, the driving member 5 includes a winch 51, a first fixed pulley 52 and a first pull rope 53. The lifting frame 6 is slidably connected to the body 1, and the sliding direction of the lifting frame 6 is the vertical direction; the winch 51 is set on the body 1, the first fixed pulley 52 is rotatably connected to the body 1, one end of the first pull rope 53 is connected to the rotating shaft of the winch 51, and the other end of the first pull rope 53 passes around the first fixed pulley 52 and is connected to the lifting frame 6.

[0059] Specifically, the winch 51 is arranged at the bottom of the machine body 1, the first fixed pulley 52 is rotatably arranged at the top of the machine body 1, one end of the first pull rope 53 is connected to the rotating shaft of the winch 51, and the other end of the first pull rope 53 is connected to the lifting frame 6 by passing through the first fixed pulley 52, so that the first pull rope 53 is gradually wound around the rotating shaft through the rotation of the winch 51, or the first pull rope 53 is released from the rotating shaft, thereby realizing the lifting or lowering of the lifting frame 6.

[0060] With this design, the position of the lifting frame 6 can be automatically adjusted, which is easy to operate. The cooperation between the winch 51 and the first pull rope 53 can stably maintain the position of the lifting frame 6, thereby ensuring the stability of the supporting platform 2 and the bumper.

[0061] In other embodiments, the driving member 5 includes a telescopic driving mechanism, wherein the telescopic driving mechanism includes an electric push rod, a cylinder or a hydraulic cylinder, etc., one end of the telescopic driving mechanism is connected to the body 1, and the output shaft of the telescopic driving mechanism extends vertically and is connected to the lifting frame 6 to drive the lifting frame 6 to rise and fall.

[0062] It can be seen that the design of the driving member 5 of the present application is not limited and can be designed according to actual needs.

[0063] In some embodiments, as Figure 1As shown, the accessory assembly jig also includes a counterweight assembly 7, which includes a counterweight member 71, a second fixed pulley 72 and a second pull rope 73. The second fixed pulley 72 is set on the body 1, one end of the second pull rope 73 is connected to the counterweight member 71, and the other end of the second pull rope 73 passes around the second fixed pulley 72 and is connected to the lifting frame 6.

[0064] Specifically, the counterweight 71 is located on the side of the body 1 away from the lifting frame 6, and the second fixed pulley 72 is set at the top of the body 1 and can be arranged in parallel with the first fixed pulley 52 in the horizontal direction. The counterweight 71 includes a plurality of counterweight blocks, which are assembled and connected to one end of the second pull rope 73. The other end of the second pull rope 73 passes around the second fixed pulley 72 and is connected to the lifting frame 6.

[0065] In this design, the counterweight 71 is used to maintain the weight balance on both sides of the body 1, avoiding the body 1 from tilting to one side, and increasing the stability of the overall structure.

[0066] In some embodiments, the accessory assembly jig further includes a control system and a limiter assembly. The control system includes a controller such as a single-chip microcomputer. The limiter assembly includes two limiters disposed on the body 1, one of which is disposed at the highest travel position of the lifting frame 6, and the other at the lowest travel position of the lifting frame 6. The lifting frame 6 is provided with a sensor, such as a switch, which is electrically connected to the winch and the controller. When the sensor on the lifting frame 6 contacts the limiter, it sends a stop signal to the controller. Upon receiving the stop signal, the controller sends a stop signal to the winch 51, causing the winch 51 to stop operating. This achieves the purpose of controlling the lifting range of the lifting frame 6 and increases safety in use.

[0067] In some embodiments, an operation panel for operating the driving member 5 is provided on the machine body 1 to increase the convenience of operation for the staff.

[0068] In some embodiments, combined Figure 1 and Figure 3 As shown, the fixing member 3 includes a first fixing member 31, a connecting rod assembly 32, and a second fixing member 33. The first fixing member 31 is disposed on the supporting platform 2 and is used to fix to the first surface of the accessory. The second fixing member 33 is connected to the supporting platform 2 via the connecting rod assembly 32 and is used to fix to the second surface of the accessory. The first surface of the accessory can be the front of the bumper, and the second surface of the accessory can be the side of the bumper.

[0069] Under this design, the first fixing member 31 and the second fixing member 33 can be connected to the front and side of the bumper respectively to achieve multi-point positioning, and the connecting rod assembly 32 can be supported on the bottom of the bumper. Combined with the multi-point fixing method, the limiting effect of the bumper can be increased to avoid the bumper shaking during operation.

[0070] In some embodiments, combined Figures 1 to 3 As shown, the connecting rod assembly 32 includes a first connecting rod 321, a second connecting rod 322, and a third connecting rod 323. One end of the first connecting rod 321 is connected to the supporting platform 2, one end of the second connecting rod 322 is hinged to the other end of the first connecting rod 321, and one end of the third connecting rod 323 is hinged to the other end of the second connecting rod 322. The second fixing member 33 is provided on the third connecting rod 323. A second hinge axis is defined between the second connecting rod 322 and the first connecting rod 321, and a third hinge axis is defined between the third connecting rod 323 and the second connecting rod 322. The second hinge axis is perpendicular to the axis of the first connecting rod 321, allowing the second connecting rod 322 to be closed toward the first connecting rod 321 or to be extended relative to the first connecting rod 321. The second hinge axis is perpendicular to the third hinge axis, allowing the third connecting rod 323 to be closed toward the second connecting rod 322 or to be extended relative to the second connecting rod 322.

[0071] Under this design, the unfolded second link 322 can be supported on the bottom of the bumper, and the second fixing part 33 on the unfolded third link 323 is connected to the side of the bumper, which can increase the support and positioning effect of the bumper and ensure the firmness of the connection. The second link 322 and the third link 323 can be folded when not in use, reducing the space occupied by the accessory assembly jig when not in use, making it easier to store and transport.

[0072] In some embodiments, as Figure 3 As shown, the first connecting rod 321 is arranged on the supporting platform 2 along the third direction, wherein the third direction is Figure 3 In the X-axis direction, the supporting platform 2 is provided with an opening along the third direction, and the first connecting rod 321 is inserted into the opening, so that the first connecting rod 321 can move relative to the supporting platform 2 along its length direction, thereby changing the distance between the ends of the two first connecting rods 321, thereby meeting the support and connection requirements of the bumpers of different models.

[0073] In the related art, when the bumper is assembled, the bumper is placed on the work surface, and the bumper paint surface contacts the work surface, which is very easy to cause scratches, resulting in poor work quality. In this regard, the present application supports the bumper by using a supporting platform 2, and the supporting platform 2 is connected to the bumper through a suction cup, and the bumper transfer operation is performed on the supporting platform 2 to avoid scratches on the bumper paint surface. The details are as follows:

[0074] In some embodiments, both the first fixing member 31 and the second fixing member 33 comprise suction cups. The suction cups can be made of rubber and attached to the bumper by being pressed against the bumper. Alternatively, the suction cups can be connected to a negative pressure pipe and a negative pressure pump, with the negative pressure provided by the negative pressure pump ensuring a secure connection. The connection method between the suction cups and the bumper is not limited and can be designed based on actual needs.

[0075] In this design, the suction cup is connected to the bumper to increase the convenience of disassembly and assembly, increase work efficiency, and the connection between the suction cup and the bumper can reduce or avoid friction with the bumper, avoiding scratches on the bumper.

[0076] In some embodiments, there are two suction cups to increase the firmness of the connection. The two suction cups are respectively installed on the supporting platform 2 through a bracket, and the bracket can move on the supporting platform 2 to adjust the position of the suction cup, thereby changing the distance between the two suction cups to meet the connection requirements of bumpers of different models.
