Description

Technical Field

[0001] This application belongs to the field of engineering machinery technology, and in particular relates to a foldable cab with built-in wiring harness. Background Technology

[0002] With societal development, construction machinery, especially 1-ton mini excavators, is increasingly widely used in narrow-condition indoor construction projects both domestically and internationally. To allow mini excavators to pass through narrow elevator doors and interior doors in high-rise buildings with height restrictions, the cab is generally required to be easily removable. Furthermore, overseas markets require excavators to be equipped with warning lights such as travel warning lights and seatbelt warning lights, necessitating that the wiring harnesses be routed from the outside or inside of the cab. However, wiring harnesses routed outside the cab are prone to damage and pose a safety hazard; moreover, the cab's waterproofing is inadequate, making wiring harness connectors susceptible to short circuits and failure during the rainy season. Summary of the Invention

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0026] Example 1

[0027] like Figures 1-4 As shown, a foldable cab with built-in wiring harness includes an upper cab assembly 1 and a lower cab assembly 2, which are fixedly hinged together. The upper cab assembly 1 is equipped with an alarm light 3, which is connected to a control terminal via a connector 4. The connector 4 is connected to the control terminal via a wiring harness 9, and the control terminal is used to supply power to the alarm light 3. The upper cab assembly 1 is equipped with an outer cover 5 for placing the connector 4. The connector 4 is arranged on the top wall of the inner cavity of the outer cover 5. The bottom of the outer cover 5 is provided with a wire hole 51, through which the wiring harness 9 enters the inner cavity of the outer cover 5 and connects to the connector 4.

[0028] By embedding the connector 4 within the outer cover 5 and placing it on the top wall of the inner cavity of the outer cover 5, short circuits caused by rainwater wetting the connector 4 are avoided. In this application, the folding of the cab is achieved through a hinge between the upper connecting plate 11 and the lower connecting plate 21.

[0029] Example 2

[0030] The difference between this embodiment and Embodiment 1 is that: a mounting base 6 is provided on the upper assembly 1 of the cab, and the alarm light 3 is mounted on the mounting base 6, which is located on the top wall of the outer cover 5. The top wall and bottom wall of the outer cover 5 are connected by side walls, and multiple side walls are arranged and connected end to end. One side wall is a detachable plate. The top of the detachable plate is located below the top wall of the outer cover 5, and the bottom wall has a rain-draining hole for draining water from inside the outer cover 5. In this embodiment, the detachable plate is connected to the other side walls by bolts. The connection between the detachable plate and the side wall is a double-layer structure, with the side wall inserted between the double layers to further improve waterproofing.

[0031] The upper cab assembly 1 is rotatably connected to the lower cab assembly 2 via a first pivot. A connector block is also inserted between the upper cab assembly 1 and the lower cab assembly 2. The connector block is detachable. The upper cab assembly 1 can be folded by rotating along the first pivot. The upper cab assembly 1 can be fixed to the lower cab assembly 2 via the connector block.

[0032] In this embodiment, the connector includes a connector pin 41. An upper connecting plate 11 is fixed on the upper assembly 1 of the driver's canopy, and two lower connecting plates 21 are arranged parallel to each other on the lower assembly 2 of the driver's canopy. A limiting groove is formed between the two lower connecting plates 21. The upper connecting plate 11 is rotatably connected to the limiting groove through a first rotating shaft, and the connector pin 41 is inserted between the upper connecting plate 11 and the lower connecting plate 21. The limiting groove can limit the rotation direction of the upper connecting plate 11 to prevent deviation.

[0033] The insertion pin 41 passes through the lower connecting plate 21, the upper connecting plate 11, and another upper connecting plate 11 in sequence, with a locking hole at one end. A locking pin 42 is inserted into the locking hole. The insertion pin 41 can be fixed by the locking pin 42, thereby fixing the upper connecting plate 11 and the lower connecting plate 21. When disassembly is required, the cab can be quickly folded by pulling out the locking pin 42 and the insertion pin 41.

[0034] This embodiment also includes an anti-loss rope 7 fixed to the cab. In this embodiment, the anti-loss rope 7 is fixed to the outside of the first rotating shaft and is connected to the locking pin 42 and the connecting pin 41. By setting the anti-loss rope 7, the locking pin 42 and the connecting pin 41 are prevented from being lost.

[0035] In this embodiment, the wiring harness 9 is built into the upper assembly 1 and the lower assembly 2 of the cab, and the length of the wiring harness 9 between the connector 4 and the control terminal is longer than the routing path length. The built-in wiring harness 9 can effectively protect the wiring harness 9, and by controlling the length of the wiring harness 9 to be longer than the routing path length, space is reserved for the stretching of the wiring harness 9 during the folding process of the cab, thereby improving the durability of the cab.

[0036] The upper assembly 1 of the cab also has a bumper ball 8. When the cab is in the folded state, the bumper ball 8 is located between the upper assembly 1 of the cab and the lower assembly 2 of the cab, to prevent the upper assembly 1 of the cab from hitting the lower assembly 2 of the cab.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
