[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0031] As Figures 1-6 shown, an embodiment of the present utility model provides an auxiliary tool for the decal of the back shell of an electric vehicle seat. The auxiliary tool is used to position the back shell of the electric vehicle seat. The back shell of the electric vehicle seat includes a housing 9, a first elastic clamping block 10 and two second elastic clamping blocks 11. The auxiliary tool includes a bottom plate 1, a stop block 2 and a boss 5;

[0032] The stop block 2 is arranged on the upper surface of the bottom plate 1. An installation groove is opened on the bottom plate 1. The boss 5 is installed in the installation groove. A first limiting notch 6 for limiting the first elastic clamping block 10 is opened on the boss 5;

[0033] The bottom plate 1 has a first side surface and a second side surface that are parallel to each other. An embedding groove 3 adapted to the housing 9 is opened on one side of the stop block 2 facing the first side surface. A positioning notch 4 for positioning the decal is opened on one side of the upper surface of the stop block 2 facing the first side surface.

[0034] Specifically, by setting the boss 5 in the mounting groove on the bottom plate 1 and the first limiting notch 6 for limiting the first elastic block 10 on the boss 5, the backrest back shell can always move from the first side to the second side before the side of the shell 9 of the backrest back shell is pressed by the embedded groove 3. When the shell 9 in the backrest back shell is partially embedded in the embedded groove 3 and its side is pressed by the embedded groove 3, it means that the backrest back shell is placed in place. After the staff aligns the decal with the positioning notch 4, the decal is pasted on the upper surface of the shell 9, so that the pasting direction of the decal can be more accurate, and the staff does not need to spend too much time to determine the direction of the decal, and the production efficiency is high. Because the position of the backrest back shell where the decal needs to be pasted is always consistent with the position of the positioning notch 4 through the cooperation of the embedded groove 3 and the first limiting notch 6, workers do not need to judge the pasting position based on experience, so there is no individual difference and judgment error between workers, which can ensure the accuracy and consistency of the decal position on the backrest back shell, and does not affect the appearance of the whole vehicle.

[0035] The embedding groove 3 is an arc-shaped groove, which is adapted to the housing 9 .

[0036] Specifically, the block 2 includes a first block, a second block and a shift rod. A T-shaped notch is provided on the upper surface of the first block. A second block adapted thereto is placed in the first T-shaped notch. The second block can only slide in the vertical direction in the first T-shaped notch. The shift rod is rotatably connected to the upper surface of the first block. The shift rod can rotate around its axis. The axis of the shift rod is perpendicular to the upper surface of the first block, so that the second block can be limited in the first T-shaped notch by rotating the shift rod. A positioning notch 4 is provided on the side of the second block facing the first side surface, so that the positioning notch 4 can be easily replaced to adapt to decals of different sizes or shapes.

[0037] According to one embodiment of the utility model, Figure 3 As shown, the mounting groove includes a communicating flaring groove 102 and a first groove 101 , the flaring groove 102 and the first groove 101 are arranged in sequence from the first side surface to the second side surface, and the boss 5 is disposed in the first groove 101 .

[0038] The expanded groove 102 can play a guiding role, making it easier to install the boss 5 into the first groove 101 .

[0039] Of course, in this embodiment, the boss 5 can be integrally formed with the base plate 1 .

[0040] According to one embodiment of the utility model, Figure 3 and Figure 1 As shown, the inner walls on both sides of the expansion groove 102 are respectively provided with first rectangular grooves 103 extending toward the second side surface;

[0041] The boss 5 has two relatively arranged first side walls 501. The first rectangular groove 103 corresponds to the first side wall 501 one by one. A second limiting notch 7 for limiting the second elastic block 11 is formed between the first rectangular groove 103 and the corresponding first side wall 501.

[0042] It should be noted that as Figure 5 and Figure 6 shown, when the back housing is placed on the bottom plate 1, the lower surface of the housing 9 in the back housing contacts the upper surface of the bottom plate 1. The first elastic block 10 and the two second elastic blocks 11 are lower than the upper surface of the bottom plate 1. Therefore, the opened first limiting notch 6 and the second limiting notch 7 not only play a role in guiding the movement of the housing 9 in the direction from the first side to the second side, but also play a role in making way for the first elastic block 10 and the second elastic block 11.

[0043] According to an embodiment of the present invention, the first rectangular groove 103 has a second side wall and a third side wall that are perpendicular to each other. The second side wall is connected to the inner wall of one side of the flared groove 102, and a second included angle is formed between the second side wall and the inner wall of one side of the flared groove 102. The second included angle is an obtuse angle.

[0044] It should be noted that the first side wall 501 forms a first included angle with the horizontal plane. The first included angle is an acute angle. The second side wall of the first rectangular groove 103 is perpendicular to the horizontal plane.

[0045] As Figure 3 shown, an arc-shaped protruding portion is provided at one end of the second side wall close to the corresponding flared groove 102 (that is, arc-shaped protruding portions are provided at one ends of the two second side walls close to the corresponding flared grooves 102). The arc-shaped protruding portions correspond to the second limiting notches 7 one by one. The arc-shaped protruding portions cooperate with the second limiting notches 7 to limit the second elastic blocks 11. Among them, the upper surface of the arc-shaped protruding portion is lower than the upper surface of the bottom plate 1, and the distance between the two arc-shaped protruding portions is smaller than the distance between the two second side walls.

[0046] As Figure 6 shown, the bottom end of the second elastic block 11 has four side faces, which are sequentially recorded as the first face, the second face, the third face, and the fourth face. The third face is an inclined face. The second face is parallel to the fourth face, and the second face and the first face are perpendicular.

[0047] During the movement of the backrest shell, the backrest shell is slightly lifted up so that the lower surface of the bottom end of the second elastic block 11 is higher than the arc-shaped protrusion, avoiding the arc-shaped protrusion and continuing to move in the direction from the first side to the second side. After the backrest shell is moved into place, at this time, the first surface of the second elastic block 11 contacts the second side wall, the second surface contacts the third side wall, and the fourth surface abuts against the arc-shaped protrusion, so that the second limiting notch 7 and the arc-shaped protrusion cooperate to limit the second elastic block 11 and prevent the backrest shell from moving in the direction from the second side to the first side, further ensuring that the position of the shell 9 on the auxiliary tooling remains unchanged, so that the position of the decal can always be guaranteed to be in the same position, thereby improving the decal efficiency as well as the accuracy and consistency of the decal orientation, and improving the aesthetics.

[0048] Further, such as Figure 6 As shown, the back shell also includes two hanging columns 12, which are respectively arranged on the side of the two second elastic blocks 11 facing the first side. When the lower surface of the shell 9 contacts the upper surface of the base plate 1, the lower surface of the two hanging columns 12 is lower than the lower surface of the base plate 1.

[0049] According to an embodiment of the present invention, in the direction from the first side surface to the second side surface, the length of the boss 5 is smaller than the length of the mounting groove.

[0050] By setting the length of the boss 5 to be smaller than the length of the mounting groove, a clearance area for making way for a hanging column 12 is formed between the end of the boss 5 and a side wall of the corresponding flared groove 102, so that the two hanging columns 12 do not affect the decals on the backrest shell.

[0051] Of course, in this embodiment, in order to prevent the side of the shell 9 from separating from the embedding groove 3 and causing the decal position to be offset, a first sliding groove can be opened on the two opposite inner walls of the expanded groove 102, and a sliding rod is slidably connected in the first sliding groove. When the side of the shell 9 is released from the embedding groove 3 and the shell 9 is partially embedded in the embedding groove 3, the sliding rod is pulled out so that the sliding rod can contact the side wall of the hanging column 12. The sliding rod and the embedding groove 3 cooperate to limit the shell 9 so that it will not move in the direction from the second side to the first side.

[0052] According to one embodiment of the utility model, Figure 4 As shown, the first limiting notch 6 includes an eight-shaped groove 602 and a second rectangular groove 601 that are connected, and the eight-shaped groove 602 and the second rectangular groove 601 are arranged in sequence from the first side surface to the second side surface;

[0053] The second rectangular groove 601 is used to limit the first elastic block 10 .

[0054] By setting the figure-eight slot 602, when the housing 9 is placed on the bottom plate 1 and pushed along the direction from the first side surface to the second side surface, its movement becomes more convenient, playing a guiding role.

[0055] Certainly, in this embodiment, the first limiting notch 6 can also be a strip-shaped groove, and the width of the strip-shaped groove is adapted to the width of the first elastic block 10. Its purpose does not deviate from the design concept of the present utility model. Therefore, it should fall within the protection scope of the present utility model.

[0056] According to an embodiment of the present utility model, the positioning notch 4 is a rectangular notch. The shape of the positioning notch 4 is set according to the shape of the decal, for accurately positioning the position of the decal to ensure the accurate placement of the decal. When the decal is rectangular, the positioning notch 4 is set as a rectangular notch.

[0057] According to an embodiment of the present utility model, along the direction from the first side surface to the second side surface, the depth of the rectangular notch is 3 - 8 mm.

[0058] When designing the positioning notch 4, the operability of the decal-applying worker is considered. The depth of the rectangular notch is set to 4 mm, which can reserve an operating space for the fingers and is more convenient for taking the decal and pasting it to the designated position.

[0059] Optionally, the depth of the rectangular notch can also be other dimensions, as long as it can meet the convenience of the worker's operation and the positioning of the decal.

[0060] According to an embodiment of the present utility model, the upper surface of the boss 5 is higher than the upper surface of the bottom plate 1.

[0061] By setting the upper surface of the boss 5 higher than the upper surface of the bottom plate 1, the two second elastic blocks 11 can be limited on both sides of the boss 5. It should be noted here that the height of the boss 5 is 2 - 8 mm higher than the upper surface of the bottom plate 1, preferably 3 mm. The lower surface of the housing 9 passes through the upper surface of the boss 5. At this time, part of the lower surface of the housing 9 contacts the upper surface of the boss 5, and part contacts the upper surface of the bottom plate 1. The housing 9 is slightly tilted until the boss 5 completely enters the cavity of the housing 9. The side surface of the housing 9 will never contact the embedding groove 3. Continuing to push the housing 9 makes the lower surface of the housing 9 fit with the upper surface of the bottom plate 1 and horizontally move along the direction from the first side surface to the second side surface, so that the embedding groove 3 abuts against the side surface of the housing 9, which means the back housing is placed in place.

[0062] According to an embodiment of the present utility model, a second groove 8 is provided on one side of the embedding groove 3 facing the second side surface.

[0063] Since the material used for the stopper 2 is relatively more, by providing the second groove 8, the material used for the stopper 2 can be saved and the cost can be reduced.

[0064] Preferably, the second groove communicates with the embedding groove 3, and a space for placing a finger can be left. Optionally, the second groove and the embedding groove 3 are not communicated, and they can be arranged at other positions as long as the purpose of reducing the usage amount and lowering the production cost can be achieved.

[0065] In this embodiment, the stop block 2, the bottom plate 1 and the boss 5 are integrally formed and made of photosensitive resin material.

[0066] Certainly, the stop block 2, the bottom plate 1 and the boss 5 can also be detachably connected and made of stainless steel material, etc. The gist does not deviate from the design concept of the present utility model. Therefore, it should fall within the protection scope of the present utility model.

[0067] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
