[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the wire harness guiding structure and the robot of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0027] Combine Figure 1 As shown, the X-axis represents the left and right direction of the whole machine, and the Y-axis represents the front and back direction of the whole machine.
[0028] The present invention provides a wiring harness guide structure comprising a housing 1, electrical components, a circuit board 3, a wiring harness 4, a heating device 5, and other components. The housing 1 is a load-bearing structure, upon which other components are mounted. The housing 1 comprises a chassis and a housing. The electrical components are connected to the circuit board 3 via the wiring harness 4. The circuit board 3 provides power to the electrical components, including power drive and control commands.
[0029] The circuit board 3 is mounted on the body 1 and controls the entire machine. Electrical components are connected to the circuit board 3 via a wiring harness 4, which transmits operating commands to the electrical components. A heating device 5 is located between the circuit board 3 and at least one electrical component, so at least one wiring harness 4 passes through the heating device 5. If the outer surface of the wiring harness directly contacts the heating device 5, the heating device 5 generates high temperatures over time, potentially damaging the insulation on the outer surface of the wiring harness. Damage to the insulation can affect the performance of the wiring harness, leading to leakage and potentially causing greater damage or personal injury.
[0030] In order to prevent the wiring harness 4 from being damaged by high temperature, at least one wire buckle 6 is provided on the body 1. There is a gap between the wire buckle 6 and the heating device 5. The wire buckle 6 is used to limit the wiring harness 4 so that there is a heat-insulating distance between the wiring harness 4 and the heating device 5, thereby preventing the heat from the outer shell of the heating device 5 from directly acting on the wiring harness. The gap between the wiring harness 4 and the heating device 5 serves as a heat-insulating area, so that the wiring harness 4 will not be damaged by the insulation layer due to excessively high temperature.
[0031] The present invention utilizes one or more wire clips 6, which are made of non-metallic materials that are less conductive to heat and provide insulation when the wiring harness 4 experiences leakage. The clips 6 act as a spacer between the wiring harness 4 and the heating device 5, thereby preventing the wiring harness from directly contacting the heating device 5 and, consequently, preventing thermal damage to the wiring harness.
[0032] The body 1 is provided with wheels 2, and the electrical component is a hub motor installed on the wheel 2. There are one or more wheels 2 with hub motors installed. The wheel 2 is installed on the body 1, and the hub motor can drive the wheel 2 to rotate, realizing the movement of the body 1. Therefore, the hub motor is an electrical component. Figure 1 As shown, the machine body 1 is equipped with four wheels, with hub motors installed on the two rear wheels. These two rear wheels serve as the driving wheels to drive the entire machine. For lawn mowing equipment, the machine body 1 is equipped with a cutterhead. The heating device 5 is a motor used to drive the cutterhead up and down. The continuous operation of the cutterhead motor generates heat, which accumulates over time to form a localized high-temperature area. Therefore, the cutterhead motor is a heat source.
[0033] Combine Figure 1 As shown in the figure, the upper part is the front part and the lower part is the rear part, among which the lower left and lower right wheels are rear wheels, each of which is provided with a hub motor. A wiring harness 4 is provided between each hub motor and the circuit board 3, and the heating device 5 is located in the middle right position. The circuit board 3 is located on the right side of the body 1. Therefore, the connection between the lower left wheel and the circuit board passes through the heating device 5, which mainly constrains the wiring harness 4 corresponding to the lower left wheel, and at the same time constrains the wiring harness corresponding to the lower right wheel.
[0034] The wiring harness led out from the lower left wheel extends roughly horizontally to the right under the wiring harness of the two wire clips 6, and then extends horizontally to the front after passing the heating device 5, making an approximately 90-degree turn. The wire clip 6 forms a barrier to the wiring harness 4, so that the wiring harness 4 cannot directly contact the outer surface of the heating device 5, forming an effective heat interval, thereby achieving a sufficient heat insulation effect and preventing the insulation layer (wiring harness skin) of the wiring harness from being burned by the heating device due to the high temperature generated by the operation of the motor. On the basis of the above scheme, the wire clip 6 of the utility model includes at least one hook portion 61, and the upper portion of the hook portion 61 has a bending structure, which is used to prevent the wiring harness 4 from detaching, and the bending direction of the bending structure of the upper portion of the hook portion 61 is away from the heating device 5. Combined with Figure 1 As shown, the wire clip 6 on the right side of the heating device 5 is only provided with a hook portion 61, and the hook portion 61 is located between the wiring harness 4 and the heating device 5. The hook portion 61 protrudes vertically upwards, blocking the wiring harness from moving toward the heating device 5 in the lateral direction.
[0035] Combine Figure 3 、 Figure 4As shown, the present invention discloses a specific structure of a hook portion 61, wherein the hook portion 61 includes a support arm 611 and a blocking hook 612. The support arm 611 is a vertically arranged structure, and the blocking hook 612 is protruding from the top of the support arm 611 to form a bent structure. The support arm 611 and the blocking hook 612 roughly form an "L"-shaped right-angled bent structure. In addition to the above structure, the hook portion 61 can also be configured as a hook structure with a vertical bottom and a circular arc at the top. In addition to the above structure, the hook portion 61 should also include a "C"-shaped arc structure.
[0036] Among the plurality of wire clips 6, at least one wire clip 6 includes two hook portions 61, and the blocking hooks 612 corresponding to the two hook portions 61 are relatively protruding. Figure 2 As shown, the two clips 6 located below (at the rear of) the heating device 5 include two hook portions 61, which are combined with Figure 3 As shown, the blocking hooks 612 of the two hook portions 61 are relatively protruding, and the distance between the ends of the two blocking hooks 612 is slightly smaller than the outer diameter of the wiring harness 4. The support arm 611 can produce a certain degree of elastic deformation. When the wiring harness 4 passes between the two blocking hooks 612, the two blocking hooks 612 are separated to the sides, and the support arm 611 is elastically deformed and bent. When the wiring harness 4 reaches below the two blocking hooks 612, the support arm 611 returns to its original shape, and the two blocking hooks 612 are re-closed, thereby preventing the wiring harness 4 from moving upward. The symmetrical distribution of the two hook portions 61 can restrain the wiring harness 4 in the lateral direction, thereby preventing the wiring harness from shaking in the lateral direction.
[0037] Combine Figure 3 As shown, the wire entry area at the upper edge of the end of the blocking hook 612 is a smooth guiding slope, forming a chamfered structure. The guiding slope can be a plane or a curved surface, which guides the wire harness to move downward. When the wire harness moves downward, it first contacts the guiding slopes at the upper edges of the two blocking hooks 612. The guiding slopes form a lateral thrust to separate the two blocking hooks 612, causing the two blocking hooks 612 to separate and open, making it easier for the wire harness to pass over the blocking hooks 612 and reach the area below.
[0038] The wire outlet area at the lower edge of the end of the blocking hook 612 is a flat surface, and the lower surface of the blocking hook 612 forms a right angle with the side wall of the support arm 611. The lower edge of the end of the blocking hook 612 is a horizontal structure, which makes it less likely to push the blocking hook 612 to both sides, and can provide a more reliable anti-detachment constraint for the wiring harness.
[0039] The cable clip 6 is fixed on the bottom plate of the body 1 and the battery compartment cover 11, and is combined with Figure 1As shown, a portion of the cable tie 6 is fixed to the bottom plate of the device body 1, while the other portion is fixed to the battery compartment cover 11. The battery compartment cover 11 can be separated and removed from the bottom plate of the device body 1. The cable tie 6 provided on the battery compartment cover 11 has two hook portions 61, while the cable tie 6 provided on the bottom plate of the device body 1 has a single hook portion 61.
[0040] The cable closure 6 is integrally injection-molded with the bottom plate of the housing 1, forming a fixed cable closure 6 thereto. The wall thickness of the cable closure 6 is roughly equal to that of the bottom plate, facilitating injection molding. The cable closure 6 is integrally injection-molded with the battery compartment cover 11 of the housing 1, forming a fixed cable closure 6 thereto. The wall thickness of the cable closure 6 and battery compartment cover 11 is roughly equal to that of the bottom plate, facilitating injection molding.
[0041] The cable clip 6 has a sufficient height to accommodate at least two wire harnesses 4 , that is, the two wire harnesses are still effectively constrained by the cable clip 6 after being stacked.
[0042] The utility model also provides a robot, comprising the above-mentioned wire harness guiding structure, and the robot can achieve the same technical effects as above.
[0043] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
