[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] The fuse boxes currently used in the industry are not waterproof, and traditional vehicle fuse boxes are placed in the cab or at a relatively high position (above the wading line) in the front cabin. However, since unmanned vehicles do not have a traditional cab or a high position for fuse boxes, using traditional fuse boxes will result in insufficient wading capabilities.

[0038] In order to ensure the waterproof performance of the fuse box body and improve the wading performance of the vehicle, this embodiment provides a waterproof safety box and an unmanned vehicle. Figures 1 to 5 The specific contents of this embodiment are described in detail.

[0039] like Figure 1 Combine Figure 2 As shown, the waterproof safety box in this embodiment includes a waterproof shell 1, a cover plate 3 and a wire-passing rubber ring 4. The waterproof shell 1 is provided with a recessed receiving groove 11, and a first assembly hole 12 is provided at the bottom of the receiving groove 11. The receiving groove 11 is used to place the fuse box body 2. The cover plate 3 is sealed and connected to the waterproof shell 1 and closes the notch of the receiving groove 11. The wire-passing rubber ring 4 has a wire threading hole 41. The wire-passing rubber ring 4 is inserted into the first assembly hole 12 and is sealed and connected to the waterproof shell 1. The connecting cable of the fuse box body 2 can be passed through the wire threading hole 41. The wire-passing rubber ring 4 can be made of EPDM material, which is the full name of EthylenePropyleneDieneMonomer (ethylene-propylene-diene monomer), which is a synthetic rubber material. The waterproof shell 1 is made of PP material (Polypropylene, polypropylene) and has a pre-embedded nut structure.

[0040] In short, the waterproof safety box provided by the present invention comprises a waterproof housing 1 having a receiving slot 11. The protected fuse box body 2 can be placed within this slot 11. The notch of the receiving slot 11 is sealed by a cover plate 3, ensuring the front of the waterproof housing 1 is sealed. A first mounting hole 12 is provided at the bottom of the slot 11. The cable-passing rubber ring 4 is assembled into this first mounting hole 12, ensuring the sealing of the back of the waterproof housing 1. This also allows the connecting cables of the fuse box body 2 to extend through the cable-passing hole 41 to connect to external electrical components. By placing the fuse box body 2 within the waterproof safety box, the waterproof performance of the fuse box body 2 is guaranteed.

[0041] Alternatively, as Figure 2 As shown, the waterproof safety box also includes a one-way vent valve 5. A second assembly hole 13 is formed through the side wall of the waterproof housing 1. The one-way vent valve 5 is located at the second assembly hole 13 and communicates with the receiving groove 11. The fuse box body 2 is installed in the completely sealed waterproof safety box. Since the fuse or relay inside the fuse box body 2 generates heat when in operation, the air pressure inside the waterproof safety box increases. The addition of the one-way vent valve 5 allows the waterproof safety box to be vented to the outside at regular intervals, while ensuring the sealing of the receiving groove 11 and balancing the internal and external pressures through ventilation.

[0042] Furthermore, if Figure 2 Combine Figure 3 As shown, the waterproof safety box also includes a sealing gasket 6. A retaining groove 14 is provided at the end of the waterproof housing 1 distal from the first assembly hole 12. The sealing gasket 6 is disposed within the retaining groove 14 and positioned between the cover plate 3 and the waterproof housing 1. The addition of the sealing gasket 6 further enhances the seal between the cover plate 3 and the waterproof housing 1. Mounting the sealing ring within the retaining groove 14 not only prevents the sealing ring from falling but also prevents it from being squeezed and deformed and overflowing, thereby enhancing the aesthetics of the box.

[0043] Furthermore, if Figure 2 As shown, the waterproof safety box also includes a first fastener 7. The cover plate 3 is provided with a plurality of first connection holes 31 spaced circumferentially, the sealing gasket 6 is provided with a plurality of second connection holes 61 spaced circumferentially, and the waterproof housing 1 is provided with a plurality of third connection holes 15 spaced circumferentially. The first fastener 7 sequentially passes through the first connection holes 31 and the second connection holes 61 and connects to the third connection holes 15. Tightening the first fastener 7 increases the extrusion force between the cover plate 3, the sealing gasket 6, and the waterproof housing 1, ensuring a secure connection among the three and improving the sealing performance of the waterproof safety box.

[0044] Optionally, the head of the first fastener 7 is provided with an anti-slip structure 71 to prevent slipping when tightening the first fastener 7. The tail of the first fastener 7 is provided with an external thread, and the third connecting hole 15 is a threaded hole. The tail of the first fastener 7 passes through the first connecting hole 31 and the second connecting hole 61 and is threadedly connected to the third connecting hole 15, making it easier to remove the cover plate 3 when replacing the fuse.

[0045] Furthermore, if Figure 2 、 Figure 4 Combine Figure 5 As shown, a first annular positioning portion 42 and a second annular positioning portion 43 are provided at one end of the wire-passing rubber ring 4, with a positioning groove 44 formed between the first annular positioning portion 42 and the second annular positioning portion 43. The positioning groove 44 engages with the first assembly hole 12. A stopper annular portion 421 is provided on the side of the outer edge of the first annular positioning portion 42 near the second annular positioning portion 43. The stopper annular portion 421 abuts against the inner wall surface of the waterproof housing 1, and the second annular positioning portion 43 abuts against the outer wall surface of the waterproof housing 1. The interference fit between the positioning groove 44 and the first assembly hole 12, and the front-to-back clamping of the stopper annular portion 421 and the second annular positioning portion 43 against the bottom wall of the waterproof housing 1, not only ensures that the wire-passing rubber ring 4 and the waterproof housing 1 are tightly fitted, but also achieves a sealed connection between the two.

[0046] Optionally, the cover plate 3 in this embodiment is made of metal, which is convenient for heat dissipation. The cover plate 3 made of stainless steel has strong corrosion resistance and prolongs its service life.

[0047] Furthermore, if Figure 2 Combine Figure 3 As shown, two opposing inner wall surfaces of the receiving groove 11 are recessed with stepped surfaces 16, with a fourth connection hole 161 provided on the stepped surface 16. The fuse box body 2 includes a support frame 21, with fifth connection holes 211 provided at each end of the support frame 21. The second fastener passes through the fifth connection holes 211 and connects to the fourth connection holes 161. The two fourth connection holes 161 and the two fifth connection holes 211 are arranged diagonally. The first fastener 7 and the second fastener can be, but are not limited to, bolts or screws.

[0048] Alternatively, as Figure 3 As shown, a reinforcing rib 17 is protruded from the bottom of the receiving groove 11 . By adding the reinforcing rib 17 , the overall structural strength of the waterproof housing 1 can be improved.

[0049] This embodiment also provides an unmanned vehicle comprising a vehicle chassis and the aforementioned waterproof safety box. The waterproof housing 1 of the waterproof safety box is provided with fixing holes 18, through which a third fastener is connected to the vehicle chassis. This improves the water-resistant performance of the entire chassis. The waterproof safety box provides waterproof protection for the fuse box body 2, facilitating its placement throughout the vehicle and expanding its adaptability to various locations.

[0050] The assembly process of the waterproof safety box in this embodiment is as follows: 1. Pass the crimped connecting cables through the wire-passing rubber ring 4 and the first assembly hole 12 of the waterproof housing 1 and insert them into the corresponding position in the fuse box body 2; 2. After all connecting cables are inserted, add waterproof cement to the connecting cables at the first assembly hole 12 (to prevent water from flowing into the receiving groove 11 through the gaps between the connecting cables), then wrap the wire-passing rubber ring 4 with waterproof PVC tape to fix the wire-passing rubber ring 4 on the connecting cables (where the waterproofing is located); 3. Snap the wire-passing rubber ring 4 into the first assembly hole 12 of the waterproof housing 1; 4. Secure the fuse box body 2 in the waterproof housing 1 and install the fuse and relay on the support frame 21 of the fuse box body 2. 5. Assemble the sealing gasket 6, cover plate 3, and vent valve.
