Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a wiring harness arrangement structure for an electric table. Background Technology

[0002] Existing electric car seat tables typically require the actuators (such as motors and control modules) within the table to be connected to an external power source or controller via wiring harnesses. To achieve functions like raising, lowering, and tilting the table, the wiring harness often needs to pass through the back of the seat and connect to the table. Traditionally, the wiring harness is simply bundled around the outside of the linkage or secured using additional cable trays or ties. This approach has the following drawbacks:

[0003] 1. Poor appearance: Exposed wiring harnesses affect the overall aesthetics and sophistication of the product.

[0004] 2. Low security: Exposed wiring harnesses are easily pulled, worn, or even accidentally snagged by users during table movement, posing a risk of short circuits and damage.

[0005] 3. Complex assembly: It requires additional fasteners and assembly steps, which increases production time and costs, and the fixing effect may not be stable.

Figure 3This is a perspective view of the application of this utility model. This utility model provides a wiring harness arrangement structure for an electric tabletop, including a connecting bracket 1, a connecting rod 2, a wiring harness 3, a wiring groove 4, and a cover plate 5. The connecting bracket 1 is connected to the seat back frame. The connecting rod 2 is rotatably connected to the connecting bracket 1 and the tabletop frame 7 via a rotating shaft assembly 6, i.e., one end of the connecting rod 2 is connected to the seat back frame, and the other end is connected to the tabletop frame 7. A recessed wiring groove 4 is formed along the length of the connecting rod 2. The wiring groove 4 follows the shape of the connecting rod 2. The cross-sectional shape of the wiring groove 4 can be an arc-shaped groove or a rectangular groove, etc., and its depth and width are determined to accommodate the required wiring harness 2. The wiring harness 3 is housed within the wiring groove 4. A cover plate 5 is provided on the connecting rod 2 to close the wiring groove 4. The shape of the cover plate 5 matches the contour of the slotted area of ​​the connecting rod 2. The cover plate 5 is preferably fixed to the connecting rod 2 by adhesive, such as strong double-sided adhesive, hot melt adhesive, structural adhesive, etc. The cover plate 5 is preferably made of plastic. The cover plate 5 is provided with at least two through holes 51 for the wire harness 3 to pass through. One end of the wire harness 3 passes through one through hole 51 to connect to the actuator such as the motor or controller inside the table, and the other end passes through the other through hole 51 to connect to the power and signal connector from the seat or chassis. A boss 52 is formed on the outer periphery of the through hole 51. The boss 52 is used to protect the wire harness 2 from damage. Depending on the actual wiring needs, a wiring groove 4 can be opened on one connecting rod 2, or multiple connecting rods can be opened with wiring grooves 4. A wire harness avoidance groove 11 is formed on the connecting bracket 1.

[0033] At the rotation node of connecting rod 2, a combination of press-fitting and screwing / riveting is used. The rotating shaft assembly 6 preferably has two forms: one includes a stepped bolt 61, a bolt sleeve 62, and a washer 63; the other includes a washer 63, a stepped rivet 64, and a rivet sleeve 65. The bolt sleeve 62 and the rivet sleeve 65 are press-fitted onto connecting rod 2 using a press-fitting fixture. The stepped bolt 61 can be used to pass through the bolt sleeve 62 and be fitted with the washer 63 to be screwed onto the corresponding component. Alternatively, the stepped rivet 64 can be used to pass through the rivet sleeve 65 and be fitted with the washer 63 to be riveted onto the corresponding component to rotatably connect and fix connecting rod 2.

[0034] The following will refer to Figures 1 to 3 The working principle of this utility model will be explained.

[0035] During assembly, first straighten the wire harness 3 and place it in the wiring groove 4 of the connecting rod 2. Then, take the cover plate 5 for pre-installation, pass both ends of the wire harness 3 through the through holes 51 respectively, and then stick the cover plate 5 to the connecting rod 2 to close the wiring groove. Finally, use a suitable rotating shaft assembly 6 to fix both ends of the connecting rod 2, and finally connect the wire harness 2 to the corresponding component.

[0036] This utility model discloses a wiring harness arrangement structure for an electric tabletop, which conceals the wiring harness, enhancing both aesthetics and safety. By creating a dedicated wiring groove inside the connecting rod and covering it with a cover plate, all wiring harnesses are completely hidden within the connecting rod, eliminating any exposure and resulting in a cleaner, more refined product appearance. Simultaneously, the wiring harness is protected by the connecting rod body, preventing damage from external pulling or wear, thus improving safety and lifespan. The integrated design simplifies assembly: the wiring harness cover plate is fixed by adhesive bonding, eliminating complex steps such as screw fixing, making assembly simple, quick, and tight, improving production efficiency. The combination of a press-fit or screw-fit shaft assembly with the adhesive cover plate ensures a smooth and reliable assembly process for the entire connecting rod assembly. The rational layout facilitates connection: two through holes are pre-set on the wiring harness cover plate, clearly defining the wiring harness's entry and exit paths. This makes the connection direction between the wiring harness and the actuators inside the tabletop and the external seat connector clear and easy to operate, facilitating standardized operations and subsequent maintenance.

[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
