[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figure 1 As shown, the frame assembly 100 of this utility model embodiment includes a side tube 1, and a groove 11 is provided on the inner side of the side tube 1. The groove 11 extends along the extension direction of the side tube 1 and is used for embedding the wire harness 200.

[0035] For example, the material of the side tube 1 can be metal such as steel, and the side tube 1 can be a V-shaped structure. The inner side of the side tube 1 is the side of the side tube 1 facing the interior of the vehicle. Taking the right side tube 1 as an example, the inner side of the side tube 1 is the left side, and the groove 11 of the frame can be provided on the left side of the side tube 1. The groove 11 is a long groove and can extend along the extension direction of the side tube 1.

[0036] In use, wire harnesses 200 such as brake cables and electronic control cables can be embedded in the groove 11. On the one hand, the groove 11 can cover and hide the wire harnesses 200, preventing them from being exposed. On the other hand, it can also protect the wire harnesses 200, ensuring the stability of their use.

[0037] The side tube 1 of the frame assembly 100 of this utility model is provided with a groove 11, and the wire harness 200 and the like can be embedded in the groove 11. This avoids the inconvenience of assembly by opening holes and also avoids the need to set additional external plastic parts by bundling, thus improving the convenience of installation.

[0038] In some embodiments, the side tube 1 includes a battery compartment tube segment 12 corresponding to the battery compartment in the inward and outward directions, and at least a portion of the groove 11 is provided in the battery compartment tube segment 12.

[0039] For example, such as Figure 2 As shown, the frame assembly 100 can have two side tubes 1, which can be arranged opposite each other in the left-right direction. The battery compartment can be installed between the two side tubes 1. The battery compartment section 12 is the part of each side tube 1 that is flush with the battery compartment in the left-right direction. Specifically, it can be... Figure 2 The part enclosed by the dashed box.

[0040] The groove 11 can be arranged only on the inner side of the battery compartment section 12 of each side tube 1, thereby making use of the internal space of the side tube 1 and avoiding the situation that the gap between the battery compartment and the side tube 1 is too narrow and it is not easy to run wires, making the arrangement of the groove 11 more targeted.

[0041] In some other embodiments, the groove 11 may extend beyond the battery compartment section 12. For example, the front end of the groove 11 may extend to the front side tube 1 portion of the battery compartment section 12, and the rear end of the groove 11 may extend to the rear side tube 1 portion of the battery compartment section 12.

[0042] In some embodiments, the length of the groove 11 in the extending direction is greater than or equal to the length of the battery compartment. For example, the length of the battery compartment can be the length in the front-to-back direction, and the length of the groove 11 in the front-to-back direction can be slightly greater than the length of the battery compartment, so that the wiring harness 200 on the side of the battery compartment can be completely embedded in the groove 11.

[0043] In some embodiments, the groove depth of the groove 11 increases first and then decreases along the extension direction of the side tube 1. For example, the groove 11 can generally extend along the front-to-back direction, and along the front-to-back direction, the groove depth of the groove 11 in the left-to-right direction can increase first and then decrease. This allows the wire harness 200 to smoothly emerge from the groove 11, avoiding the situation where the wire harness 200 emerges vertically from the end of the groove 11, reducing the bending degree of the wire harness 200, and thus ensuring the stability of the wire harness 200 in use.

[0044] In some embodiments, the side pipe 1 includes a first inclined pipe section 13, a second inclined pipe section 14, and a middle pipe section 15. The first inclined pipe section 13 and the second inclined pipe section 14 are both arranged at an inclination. The middle pipe section 15 is connected between the first inclined pipe section 13 and the second inclined pipe section 14. A groove 11 is distributed throughout the middle pipe section 15, and one end of the groove 11 extends to the first inclined pipe section 13, and the other end of the groove 11 extends to the second inclined pipe section 14.

[0045] For example, such as Figure 1 As shown, the intermediate pipe section 15 can be arranged generally horizontally and can extend in the front-to-back direction. The first inclined pipe section 13 can be connected to the front side of the intermediate pipe section 15, and the first inclined pipe section 13 can be arranged inclined downward in the direction from front-up to rear-down. The second inclined pipe section 14 can be connected to the rear side of the intermediate pipe section 15, and the second inclined pipe section 14 can be arranged inclined upward in the direction from front-down to rear-up. The aforementioned battery compartment pipe section 12 can include the entire intermediate pipe section 15, a portion of the rear end of the first inclined pipe section 13, and a portion of the front end of the second inclined pipe section 14.

[0046] The groove 11 can penetrate the intermediate pipe section 15 in the front-to-back direction, and the front end of the groove 11 can extend to the rear end of the first inclined pipe section 13, while the rear end of the groove 11 can extend to the front end of the second inclined pipe section 14.

[0047] In some embodiments, such as Figure 1 As shown, the groove 11 includes an intermediate groove section 111, a first groove section 112, and a second groove section 113.

[0048] The intermediate groove section 111 is located in the intermediate pipe section 15, and the groove depth of the intermediate groove section 111 is consistent along the extension direction. That is, the groove depth of the intermediate groove section 111 in the left and right directions can remain unchanged from front to back, thereby ensuring that the wire harness 200 is fully embedded.

[0049] The first groove segment 112 is located on the first inclined tube segment 13 and connected to one end of the intermediate groove segment 111. The groove depth of at least a portion of the first groove segment 112 gradually increases along the direction toward the intermediate groove segment 111. The second groove segment 113 is located on the second inclined tube segment 14 and connected to the other end of the intermediate groove segment 111. The groove depth of at least a portion of the second groove segment 113 gradually increases along the direction toward the intermediate groove segment 111.

[0050] For example, a first groove segment 112 can be connected to the front end of an intermediate groove segment 111. The groove depth of the first groove segment 112 in the left-right direction can gradually increase from front to back until it is substantially the same as the groove depth of the recess 11 of the intermediate groove segment 111. A second groove segment 113 can be connected to the rear end of an intermediate groove segment 111. The groove depth of the second groove segment 113 in the left-right direction can gradually increase from back to front until it is substantially the same as the groove depth of the recess 11 of the intermediate groove segment 111.

[0051] This allows the wire harness 200 to smoothly exit the groove 11 via the first groove segment 112 and the second groove segment 113, avoiding excessive bending of the wire harness 200 and ensuring the stability of the wire harness 200 structure and its usage.

[0052] In some embodiments, the frame assembly 100 includes a support strip 2, one end of which is connected to a side tube 1, and the other end of which is connected to the battery compartment. The support strip 2 is sealed at the opening of the groove 11 to prevent the wiring harness 200 from coming out of the groove 11.

[0053] For example, such as Figure 2 As shown, the support strip 2 can be a long strip structure. The support strip 2 can be arranged to extend in the vertical direction. The top end of the support strip 2 can overlap the side tube 1 and be connected and fixed to the side tube 1. The bottom end of the support strip 2 can be connected and fixed to the battery compartment.

[0054] The support strip 2 can be located inside the side tube 1. After assembly, the support strip 2 can block part of the groove 11, thereby preventing the wire harness 200 from easily coming out of the groove 11.

[0055] In some embodiments, the side tube 1 is provided with a locking member 3, and one end of the support strip 2 overlaps with and is detachably connected to the locking member 3. For example, as Figure 2 and Figure 3 As shown, the locking component 3 can be a casting, and the locking component 3 can be a long strip that can be fixed to the top side of the side tube 1 by welding. The locking component 3 can be provided with threaded holes, etc.

[0056] During assembly, the lugs and other structures at the top of the support bar 2 can overlap the locking component 3, and then the lugs and locking component 3 can be connected and fixed by screws or other fasteners. This facilitates the assembly and fixing of the support bar 2.

[0057] In some embodiments, there are multiple support strips 2, and the multiple support strips 2 are arranged at intervals along the extending direction. For example, as Figure 2 As shown, each side tube 1 can be provided with two support strips 2 on its inner side. The two support strips 2 can be arranged at intervals along the front and back direction. In this way, on the one hand, the assembly needs of connecting and fixing the battery compartment by means of multiple support strips 2 are fully met, and on the other hand, the number of limiting points of the wire harness 200 in the groove 11 can be increased, further preventing the wire harness 200 from coming out of or moving out of the groove 11.

[0058] In some embodiments, the side tubes 1 are arranged in pairs, with the two side tubes 1 arranged opposite each other in the width direction of the frame assembly 100, and each side tube 1 has a groove 11 on its inner side. For example, the two side tubes 1 can be arranged in a substantially mirror-symmetrical manner in the left-right direction, and each side tube 1 can have a groove 11 on its inner side, so that the wiring harness 200 can be embedded into any one of the side tubes 1 according to actual assembly needs, thereby improving the convenience and flexibility of installation.

[0059] In some embodiments, such as Figure 4 As shown, the cross-section of the groove 11 is U-shaped, thus fully meeting the assembly requirements for embedding the wire harness 200. In some other embodiments, the cross-section of the groove 11 may also be semi-circular, V-shaped, or other shapes.

[0060] In some embodiments, the groove 11 is stamped onto the side tube 1. For example, as... Figure 4 As shown, the side tube 1 can be formed by processing a round tube. During processing, a stamping device can be used to stamp one side of the round tube, and after stamping, a groove 11 that is recessed into the inside of the round tube can be formed. This facilitates the processing of the groove 11.

[0062] The vehicle of this embodiment includes a wiring harness 200 and a frame assembly 100. The frame assembly 100 can be the frame assembly 100 described in any of the above embodiments, such as... Figure 4 As shown, the control lines, brake lines, and other wiring harnesses 200 are fitted into the groove 11.
