[0041] Example 1
[0042] In this embodiment, Figure 1 This is a complete structural diagram of the tail box provided in an embodiment of the present utility model, and for the purpose of showing the structure more clearly, Figures 2-7 The image only shows the protrusions and connecting parts on the lid, as well as part of the box's structure.
[0043] Please see Figure 1 and Figure 2This embodiment provides a tail box, which includes a lid 1, a connector 2, and a body 3. The connector 2 is disposed at the connection between the lid 1 and the body 3. The lid 1 is provided with a protrusion 11, and the connector 2 is provided with a first groove 21 that matches the protrusion 11. The protrusion 11 can be inserted into the first groove 21 and is rotatably connected to the connector 2 via a rotating shaft 4. The body 3 is provided with a second groove 31 that matches the connector 2. The connector 2 can be inserted into the second groove 31 and is connected to the body 3.
[0044] When assembling this tailgate, please refer to Figure 3 First, insert the protrusion 11 on the box cover 1 into the first groove 21 of the connector 2, and assemble the rotating shaft 4 so that the protrusion 11 is rotatably connected to the connector 2. Please refer to [link to previous section]. Figure 4 Then insert the connector 2 into the second slot 31 and connect the connector 2 to the box 3. The operation is simple, convenient, time-saving and labor-saving.
[0045] In this embodiment, the tail box uses a connector 2 instead of the liner or decorative ring used in the prior art. The connector 2 is only set at the connection between the cover 1 and the body 3, and is located in the second groove 31 of the body 3. The liner or decorative ring is a structure that surrounds the body 3 in a circle. Therefore, the connector 2 is smaller in volume than the liner or decorative ring, which reduces the amount of material used in the connector 2 and reduces the material cost of the tail box to a certain extent, thus alleviating the technical problem of high cost of electric vehicle tail boxes in the prior art.
[0046] On the other hand, the smaller size of connector 2 reduces the connection area between connector 2 and box 3. Therefore, when connecting connector 2 to box 3, it is not necessary to use a large number of connection structures to firmly connect connector 2 to box 3. The use of fewer connection structures further reduces the cost of tail box, as well as the assembly steps and time of tail box, and improves the assembly efficiency of tail box.
[0047] Preferably, please refer to Figure 2 and Figure 5 In this embodiment, the protrusion 11 extends towards the box body 3 along the depth direction of the lid 1. Compared to the prior art where the protrusion on the lid protrudes outward relative to the tail box in a cantilever structure, the protrusion 11 in this embodiment is inserted downward into the connector 2, thus not protruding outward relative to the tail box in a cantilever structure, which improves the aesthetics of the tail box, and the pivot 4 provided on the protrusion 11 is not easy to fall off.
[0048] Preferably, please refer to Figure 2 and Figure 5In this embodiment, there are two protrusions 11 on the box cover 1 and two connectors 2. The two protrusions 11 are respectively inserted into the first grooves 21 of the two connectors 2. There are two second grooves 31 on the box body 3, and the two connectors 2 are respectively inserted into the two second grooves 31.
[0049] This design makes the connection between the lid 1 and the body 3 more secure and reliable, and makes the rotation of the lid 1 relative to the body 3 more stable and smooth.
[0050] Preferably, please refer to Figure 2 and Figure 5 In this embodiment, the two protrusions 11 are connected by a connecting part 12, which is connected to the box cover 1.
[0051] Preferably, the two protrusions 11 and the connecting part 12 are integrally formed. For example, the whole formed by the combination of the two protrusions 11 and the connecting part 12 can be formed in one step by stamping, injection molding or other methods. This arrangement ensures the sealing performance of the product in terms of processing, ensures the consistency of the finished product in terms of process, and has high production efficiency.
[0052] Preferably, please refer to Figure 6 and Figure 5 In this embodiment, the connector 2 is bent outward near the opening of the first groove 21 to form a folded edge 22. A first connecting hole is provided on the folded edge 22, and a second connecting hole 32 is provided on the housing 3. The threaded connector 5 can be inserted into the first connecting hole and screwed into the second connecting hole 32.
[0053] The folded edge 22 facilitates the connection between the connector 2 and the box body 3 via the threaded connector 5, making the assembly of the tail box more convenient and further improving the assembly efficiency of the tail box.
[0054] Preferably, please refer to Figure 6 In this embodiment, two first connecting holes are provided on the folded edge 22, and along the depth direction perpendicular to the first groove 21, the two first connecting holes are respectively provided on both sides of the folded edge 22.
[0055] In other words, correspondingly, there are also two second connection holes 32 on the housing 3, with the two second connection holes 32 corresponding to the two first connection holes respectively. This arrangement makes the connection between the connector 2 and the housing 3 more secure.
[0056] Preferably, please refer to Figure 3 In this embodiment, a stepped groove 33 matching the folded edge 22 is also provided at the groove opening of the box body 3 near the second groove 31.
[0057] With this configuration, when the connector 2 is inserted into the second groove 31, the folded edge 22 can be positioned within the stepped groove 33. The stepped groove 33 can limit the folded edge 22, preventing it from moving relative to the housing 3, thus preventing the connector 2 from moving relative to the housing 3, and further making the connection between the connector 2 and the housing 3 more reliable and secure.
[0058] Preferably, please refer to Figure 2 In this embodiment, the protrusion 11 is provided with a first rotating hole 13, and the connector 2 is provided with a second rotating hole. The rotating shaft 4 can be inserted into the first rotating hole 13 through the second rotating hole so that the protrusion 11 can rotate relative to the connector 2. Thus, after the connector 2 is connected to the box body 3, the box cover 1 can rotate relative to the box body 3.
[0059] Preferably, please refer to Figure 5 and Figure 6 In this embodiment, after the connector 2 is inserted into the second slot 31, the connector 2 is connected to the housing 3 by the threaded connector 5.
[0060] For this configuration, please refer to the following when assembling the tailgate: Figure 6 First, insert the protrusion 11 on the box cover 1 into the first groove 21 of the connector 2, and then insert the rotating shaft 4 into the first rotating hole 13 from the second rotating hole, so that the protrusion 11 is rotatably connected to the connector 2. Please refer to [link to previous section]. Figure 7 Then, insert the connector 2 into the second slot 31, and connect the connector 2 to the box 3 with the threaded connector 5 such as bolts, screws or studs. The operation is simple, convenient and saves time and effort.
[0061] It should be noted that in the prior art, since the inner lining is set around the inner circumference of the box and the decorative ring is also set around the opening of the box, the connection area between the inner lining and the decorative ring and the box is relatively large. Therefore, a large number of threaded connectors are required to firmly connect the inner lining or decorative ring to the box. For example, in the prior art, at least seven threaded connectors are generally required. The use of more threaded connectors further increases the cost of the tail box, as well as the assembly steps and time, and reduces the assembly efficiency.
[0062] In this embodiment, the tail box uses a connector 2 instead of the liner or decorative ring used in the prior art. The connector 2 is only set at the connection between the cover 1 and the body 3, and is located in the second groove 31 of the body 3. The liner or decorative ring is a structure that surrounds the body 3 in a circle. Therefore, the connector 2 is smaller in volume than the liner or decorative ring, and the connection area between the connector 2 and the body 3 is smaller. Therefore, it is not necessary to use a large number of threaded connectors 5 to firmly connect the connector 2 to the body 3. For example, two threaded connectors 5 can be used. The use of fewer threaded connectors 5 further reduces the cost of the tail box, reduces the assembly steps and time of the tail box, and improves the assembly efficiency.
[0063] In summary, the tail box of this embodiment simplifies the inner lining or decorative ring into two connectors 2. After the connectors 2 are connected to the protrusions 11 of the box cover 1, the pivot 4 can be easily installed. Then, the connectors 2 can be fixed to the box body 3 with four threaded connectors 5. This saves on the cost of threaded connectors 5 and materials, and also reduces the assembly time of the tail box.
