Technical Field

[0001] This utility model relates to the technical field of lawnmower accessories, and in particular to a high-environment-adaptive lawnmower wiring harness anti-vibration and waterproof component. Background Technology

[0002] Lawn mowers are a common gardening tool widely used in outdoor lawn mowing. Wiring harnesses are a crucial component of the lawn mower's electrical system, responsible for the transmission of power and signals between various electrical components. However, lawn mowers operate in complex environments, typically facing challenges such as damp grass, rain damage, and strong vibrations during operation.

[0003] However, in the existing technology, the protection measures for existing lawnmower wiring harnesses are relatively simple, mostly using only ordinary insulating sleeves, which have poor vibration resistance. Strong vibrations can cause loosening and wear between the wiring harness and connecting parts, affecting the stable transmission of signals and power, reducing the reliability and service life of the lawnmower, and increasing maintenance costs and downtime. Therefore, a high-environment-adaptive lawnmower wiring harness vibration-resistant and waterproof component is proposed. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a high-environment-adaptive lawnmower wiring harness anti-vibration and waterproof component, including a waterproof shell 1, an anti-vibration sleeve 2 fitted on the outer wall of the waterproof shell 1, a mounting base 3 fixedly installed on the lower surface of the anti-vibration sleeve 2, a silicone buffer block 4 fixedly installed inside the groove at the lower end of the mounting base 3, two sets of silicone buffer pads 5 fixedly installed at the lower end of the mounting base 3, and multiple sets of mounting holes 6 through the upper end of the mounting base 3 and near the edges of both ends, with one end of each set of silicone buffer pads 5 fixed to both ends of the silicone buffer block 4 respectively.

[0024] The specific settings and functions of this embodiment are described in detail below. The waterproof shell 1 serves as the main frame of the entire component. It is integrally injection molded from an alloy material of polycarbonate and acrylonitrile-butadiene-styrene copolymer, which has high mechanical strength and weather resistance, and can provide a solid protective foundation for the internal wire harness. One end of the shell has five sets of cable holes 12 for the wire harness to pass through, so as to realize the arrangement and extension of the wire harness inside the waterproof shell 1.

[0025] The vibration damping sleeve 2 is fitted on the outer wall of the waterproof housing 1 and is made of a highly elastic and highly damped rubber material. This material has excellent vibration absorption capacity and can further buffer and weaken the vibration energy transmitted to the waterproof housing 1 through its own elastic deformation, adding an extra layer of vibration protection to the waterproof housing 1 and the internal wiring harness.

[0026] Mounting base 3 is fixedly installed on the lower surface of anti-vibration sleeve 2, serving as a connection and support. A groove is provided at its lower end, inside which a silicone buffer block 4 is provided for installation. Simultaneously, multiple sets of mounting holes 6 are provided through the upper end of mounting base 3, near the edges of both ends, to secure the entire component to the lawnmower body, ensuring stable installation.

[0027] The silicone buffer block 4 is fixedly installed inside the groove at the lower end of the mounting base 3. It is made of high-toughness silicone material, which has good elasticity and buffering performance. It can effectively absorb and disperse the vibration transmitted from the lawnmower body and reduce the impact of vibration on the upper structure.

[0028] Two sets of silicone buffer pads 5 are fixedly installed at the lower end of the mounting base 3, and one end of each set of silicone buffer pads 5 is fixed to both ends of the silicone buffer block 4. The silicone buffer pads 5 are also made of high-quality silicone and work together with the silicone buffer block 4 to further enhance the overall vibration resistance and form a multi-layer vibration buffer system.

[0029] The properties of the material used in the vibration damping sleeve 2 enable it to effectively absorb vibration energy, reduce the direct impact of vibration on the waterproof housing 1, provide additional vibration protection for the internal wiring harness, and reduce the risk of the wiring harness being damaged by vibration.

[0030] The mounting base 3, silicone buffer block 4, and silicone buffer pad 5 are designed to ensure the stability of the connection between the component and the lawnmower body. The multiple sets of mounting holes 6 of the mounting base 3 ensure the stability of the connection between the component and the lawnmower body. The silicone buffer block 4 and the two sets of silicone buffer pads 5 work together to form a multi-layer vibration buffer structure, which can efficiently absorb and disperse vibration energy, significantly reduce the vibration transmitted from the machine body to the waterproof outer shell 1 and the internal wiring harness, and enhance the overall vibration resistance.

[0031] Example 2: Figure 1 , Figure 3 and Figure 4 As shown, one end of the waterproof housing 1 has five sets of cable holes 12. Rubber sealing rings 7 are installed at both ends of the waterproof housing 1 and at the opening of each set of cable holes 12. A first circular groove 8 is opened inside each set of cable holes 12 and near the two side edges. A first gasket 9 is installed inside each first circular groove 8. A second circular groove 10 is opened on the inner wall of each set of rubber sealing rings 7. A second gasket 11 is installed inside each second circular groove 10.

[0032] The overall effect of this embodiment is that the rubber sealing ring 7 is installed at both ends of the waterproof housing 1 and located at the opening of each group of cable holes 12. It is made of fluororubber material. Fluororubber has excellent high and low temperature resistance and chemical corrosion resistance. It can fit tightly to the opening edge of the cable hole 12 and the wire harness passing through it, effectively preventing moisture, dust and other impurities from entering the interior of the waterproof housing 1. The multiple cooperation of the rubber sealing ring 7, the first washer 9 and the second washer 11 forms a tight sealing system, which can effectively prevent moisture, dust and other impurities from entering the interior of the waterproof housing 1, and greatly improve the waterproof and dustproof performance.

[0033] The five sets of cable holes 12 can meet the needs of multiple wire harnesses passing through at the same time, and adapt to the wire harness layout of different lawnmower electrical systems. Each set of cable holes 12 has a No. 1 circular groove 8 inside and near the two side edges. Each set of No. 1 circular groove 8 has a No. 1 washer 9 inside. The No. 1 washer 9 is made of elastic rubber material. When the wire harness passes through the cable hole 12, it can make close contact with the surface of the wire harness, further fill the gap, enhance the sealing and vibration resistance of the cable hole 12, and reduce the direct friction between the wire harness and the inner wall of the cable hole 12.

[0034] Each set of rubber sealing rings 7 has a second circular groove 10 on its inner wall, and a second washer 11 is provided inside each set of second circular grooves 10. The second washer 11 is made of high elastic silicone material and works with the rubber sealing ring 7 to form a tighter sealing structure between the rubber sealing ring 7 and the wire harness, further improving the waterproof and dustproof performance, and also buffering the impact of wire harness vibration on the rubber sealing ring 7.

[0035] The placement of gasket 9 and gasket 11 not only enhances the sealing performance but also reduces friction between the wire harness and the inner wall of the cable hole 12 and the rubber sealing ring 7 during vibration, protecting the insulation layer of the wire harness and extending its service life.

[0036] The usage and working principle of this device: The mounting base 3 can be installed on the lawnmower body by cooperating with the mounting hole 6 and the external bolt. When the vibration is transmitted from the lawnmower body, it first comes into contact with the silicone buffer pad 5 at the lower end of the mounting base 3. The silicone buffer pad 5 is made of high-quality silicone material, which has good elasticity and toughness. It will undergo elastic deformation due to vibration, converting some of the vibration energy into its own elastic potential energy, thereby initially absorbing and dispersing the vibration.

[0037] Then, the remaining vibration energy is transferred to the silicone buffer block 4 in the groove at the lower end of the mounting base 3. The silicone buffer block 4 is connected to two sets of silicone buffer pads 5 to form an integrated buffer structure, which can further absorb vibration energy through deformation and disperse the vibration energy in all directions to reduce concentrated impact.

[0038] Finally, after being buffered by the silicone buffer block 4 and the silicone buffer pad 5, some vibration will still be transmitted to the mounting base 3, and then to the waterproof shell 1 through the anti-vibration sleeve 2. The anti-vibration sleeve 2 is fitted on the outer wall of the waterproof shell 1 and is made of highly elastic and highly damped rubber material. Its internal molecular structure will generate friction under vibration, converting vibration energy into heat energy and dissipating it, further weakening the intensity of vibration and reducing the direct impact of vibration on the waterproof shell 1.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
