DETAILED DESCRIPTION

[0034] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0035] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0036] like Figure 1 and Figure 2 As shown, the present application provides a vehicle-mounted device 1, which is used to be installed in the rear bucket 80 of a vehicle. The vehicle-mounted device includes a housing 10, a cover 20, a lifting platform 30, a driving device 40, a transmission force amplifying device 50, a fixing frame 60, a partition 70 and the rear bucket 80.

[0037] The housing 10 is secured to the rear bucket 80 and forms a storage space 100 with the rear bucket 80. Storage space 100 can be used to house equipment such as drones. The housing 10 has an upward-facing opening 110, over which the cover 20 slides. Sliding the cover 20 over the opening 110 improves operational convenience, making it easier to move equipment within storage space 100.

[0038] The lifting platform 30, the drive unit 40, and the transmission booster 50 are installed within the accommodation space 100. The transmission booster 50 is power-connected to the lifting platform 30 and the drive unit 40, respectively, to enable the lifting platform 30 to ascend or descend. The transmission booster 50 increases the force transmitted from the drive unit 40 to the lifting platform 30, making the lifting platform 30 operate more smoothly and capable of carrying greater weight.

[0039] The present application also provides a vehicle comprising a rear bucket 80 and the aforementioned on-board device 1, with the on-board device 1 assembled to the rear bucket 80. Because the on-board device 1 is highly user-friendly and the lifting platform 30 can carry a greater weight, the vehicle of the present application provides a superior user experience. The vehicle of the present application can be a fuel-powered vehicle, an electric vehicle, or a hybrid vehicle, with no specific limitation on the specific vehicle type.

[0040] The fixed frame 60 is fixed to the housing 10. The lifting platform 30, the drive device 40, and the transmission booster 50 can be mounted on the fixed frame 60. Because the frame structure has high strength, the fixed frame 60 and the fixed lifting platform 30, the drive device 40, and the transmission booster 50 are fixed to improve the overall structural strength of the vehicle-mounted device 1.

[0041] The divider 80 separates the storage space 100 into a lifting space 101 and a storage space 102. The lifting space 101 and the storage space 102 are spaced apart along the sliding direction of the cover 20. The lifting platform 30, the drive device 40, and the transmission force amplification device 50 are installed in the lifting space 101. The use of the divider 80 to separate the storage space 100 increases the diversity of spatial forms and improves the user experience. The divider 80 can include multiple panels to further increase the diversity of spatial forms.

[0042] Please also refer to Figure 3 and Figure 4 As shown, the housing 10 includes a top plate 11, a pair of side plates 12 extending downward from both sides of the top plate 11, a rear plate 13 connecting the pair of side plates 12, and a support plate 14. An opening 110 is provided in the top plate 11. The housing 10 is provided with a shielding portion 111 around the opening 110. An abutment portion 112 may be provided at one end of the top plate 11 away from the rear plate 13. The abutment portion 112 is provided with a slot 1121 for mounting elastic components such as rubber.

[0043] The rear panel 13 is located at one end of the side panels 12 near the storage space 102. In one embodiment, at least one of the side panels 12 and the rear panel 13 is provided with a window 14, which communicates with the storage space 102. The provision of window 14 allows users to access items through it, improving the convenience of managing items in the storage space 102.

[0044] The window 14 may be provided with a shielding cover 141 that can be opened and closed. When the storage space 102 is not needed, the shielding cover 141 is closed to protect the storage space 102 and prevent debris from entering. When the storage space 102 is needed, the shielding cover 141 is opened to take or put items.

[0045] The shielding cover 141 may be provided with a lock 142 to keep the shielding cover 141 in a closed state, preventing it from opening with the bumps of the vehicle, thereby ensuring the airtightness of the storage space 102. The shielding cover 141 may be provided with a support rod 143 on the inside to assist in opening the shielding cover 141 and improve the convenience of operation.

[0046] The opening 110 may include a lifting opening 1101 located above the lifting space 101 and a storage opening 1102 located above the storage space 102. When closed, the lid 20 covers both the lifting opening 1101 and the storage opening 1102. When open, the lid 20 covers the storage opening 1102 and exposes the lifting opening 1101. In the open state, the lid 20 only needs to be opened to expose the lifting opening 1101, reducing the length of the overhanging rear end of the lid 20 and improving the structural strength of the lid 30 when open.

[0047] In this embodiment, the housing 10 may further include a support plate 15. The support plate 15 is mounted to the storage opening 1102. Since the cover 20 covers the storage opening 1102 when open, the support plate 15 provides support for the cover 20, further enhancing the structural strength of the cover 20 when open. Furthermore, the support plate 15 provided at the storage opening 1102 provides a shield, preventing external debris such as dust and rain from entering the storage space 102.

[0048] Because the cover 20 is highly robust when open, in some embodiments, the cover 20 itself can serve as a forced landing platform for items such as drones. If a drone is unable to land properly on the support surface 300, it can first land on the cover 20 and then be manually stored. In this embodiment, relevant indicators, such as the letter "H," can be provided on the upper surfaces of the support surface 300 and the cover 20 to indicate the drone's landing location.

[0049] The housing 10 may be internally provided with multiple proximity switches 16. Proximity switches 16 are located at both the starting and ending positions of the front end of the cover 30 to detect whether the cover 30 is properly opened or closed. To enhance the strength of the housing 10, reinforcing ribs 17 may also be provided internally. These ribs 17 may connect the top panel 11 to the side panels 12. They may also connect the top panel 11 to the rear panel 13.

[0050] Please also refer to Figure 5 As shown, the cover 20 includes a cover body 21. In one embodiment, the cover 20 is provided with a rack 22. The rack 22 is located on the side of the cover body 21 facing the opening 110. The rack 22 is located in the middle of the cover 20 and is arranged along the front and rear direction of the vehicle. In this embodiment, as shown in FIG. Figure 3 and Figure 4 As shown, a motor 18 may be fixed to the housing 10 , and the motor 18 is assembled with a gear 19 to perform rack and pinion transmission to drive the cover 20 to move, thereby improving the movement stability of the cover 20 .

[0051] Specifically, in an embodiment where the support plate 15 is mounted to the storage opening 1102, the motor 18 can be mounted below the support plate 15. The support plate 15 is provided with a through hole 151. The gear 19 passes through the support plate 15 and mates with the rack 22. This arrangement improves space utilization, making the drive and transmission components of the cover 20 more compact, thereby leaving more storage space in the storage space 100.

[0052] like Figure 5 As shown, in one embodiment, the front surface 211 of the cover body 21 may be provided with a ridge 212. Figure 3 As shown, the ridge 212 can abut against the slot 1121 to limit the position. In the embodiment where the slot 1121 is equipped with an elastic member, the ridge 312 can abut against the elastic member to seal and protect the stored items.

[0053] like Figure 5 As shown, in one embodiment, the cover 20 may be provided with a sliding member 23. Figure 4 As shown, the sliding member 23 extends from the cover 20 through the opening 110 to the bottom of the shielding portion 111. The sliding member 23 is slidably mounted on the bottom side of the shielding portion 111. The cover 20 slides relative to the housing 10 via the sliding member 23 and the shielding portion 111. Therefore, the position where the cover 20 and the housing 10 slide relative to each other is located below the shielding portion 111, which can prevent erosion by rain, dust, and other debris, ensuring the stability of the sliding process.

[0054] Specifically, in the left-right direction of the vehicle, the shielding portion 111 can be located on both sides of the opening 110, and the number of sliding members 23 is set to a pair, distributed on the left and right sides of the cover body 21. The sliding members 23 slide with the lower side of the shielding portion 111 to drive the cover body 20 to move along the front-rear direction of the vehicle.

[0055] like Figure 4 and Figure 5 As shown, in one embodiment, a guide bar (not shown) is formed on the lower side of the shielding portion 111. The guide bar extends along the sliding direction of the cover 20. The slider 23 is provided with a positioning groove 230, and the guide bar is installed in conjunction with the positioning groove 230. By providing the positioning groove 230 and the projection to form the guide bar, the slider 23 can be limited to prevent the cover 20 from swinging during movement.

[0056] The specific structural form of the sliding member 23 is not limited. Figure 7As shown, the sliding member 23 may include a first plate 231, a second plate 232, a third plate 233, and an abutment block 234. The first plate 231 is horizontally disposed and fixed to the cover body 21. The second plate 232 is vertically disposed and fixed to the first plate 231. The third plate 233 is horizontally disposed and fixed to the second plate 232. The abutment block 234 is assembled to the upper portion of the third plate 233 and engages with the shielding portion 111.

[0057] The first, second, and third plates 231, 232, and 233 form a "Z"-shaped structure, allowing the slider 23 to extend to the underside of the shielding portion 111, providing greater strength. Each slider 23 may include two abutment blocks 234, located at the front and rear ends of the third plate 233, to further enhance the stability of the cover 20 during movement.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment, the cover body 21 may be provided with a roller assembly 24 that engages with the upper surface of the shielding portion 111. During movement of the cover 20, the roller assembly 24 rolls on the upper surface of the shielding portion 111, ensuring smooth movement of the cover 20. Furthermore, the slider 23 and the roller assembly 24 can clamp the shielding portion 111 from both sides, further improving movement stability.

[0059] like Figure 5 As shown, in one embodiment, the cover body 21 may be provided with a limit bracket 25. The limit bracket 25 is L-shaped. When the cover body 20 is closed, the limit bracket 25 can limit the upper and lower directions of the cover body 20 to prevent the cover body 20 from being opened due to impact during the bumpy process of the vehicle.

[0060] like Figure 6 As shown, the lifting platform 30 includes an upward-facing support surface 300, which is provided with object securing holes 301. The provision of object securing holes 301 provides securement for stored items, improving their stability. Multiple object securing holes 301 can be provided to meet the securing requirements of different items, such as drones and brackets.

[0061] The lifting platform 30 may include a load-bearing platform 31 and a transmission platform 32. The load-bearing platform 31 is used to place items, and a load-bearing surface 300 is provided on the load-bearing platform 31. The transmission platform 32 is used to connect to the transmission force-boosting device 50. By dividing the lifting platform 30 into the load-bearing platform 31 and the transmission platform 32, the load-bearing platform 31 and the transmission platform 32 can be designed and manufactured separately, and their structures can be strengthened separately. The transmission platform 32 can be strengthened to increase the input force, while the load-bearing platform 31 can be strengthened to increase the load-bearing capacity.

[0062] like Figure 6 and Figure 7 As shown, a chute 311 and an escape groove 312 can be provided on the carrying platform 31. The chute 311 abuts against the fixed frame 60 to guide the carrying platform 31 during movement. The escape groove 312 is used to avoid components, such as the distribution box 64.

[0063] Please also refer to Figure 9 and Figure 10 As shown, the transmission platform 32 may include a mounting frame 321 and a connecting plate 322 assembled to the mounting frame 321. A connecting block 323 is provided on the connecting plate 322, which is connected to the transmission force amplification device 50. The mounting frame 321 is arranged horizontally, the connecting plate 322 is arranged vertically, and the load-bearing platform 31 is fixed to the mounting frame 321. The frame structure has high structural strength, which can further increase the weight of items that the lifting platform 30 can carry.

[0064] like Figure 6 As shown, the transmission booster 50 may include a lead screw 51. The lead screw 51 is positioned along the height direction and is power-connected to the drive unit 40 and the lifting platform 30. This lead screw mechanism can transmit greater force, improving the stability of the lifting platform 30 and enabling it to carry heavier objects. In other embodiments, the specific structure of the transmission booster 50 is not limited.

[0065] In one embodiment, if Figure 9 As shown, the drive device 40 includes a drive body 41 and a first sprocket 42 that is dynamically assembled with the drive body 41. A second sprocket 52 is provided at one end of the lead screw 51 near the drive device 40. The transmission booster 50 also includes a chain 53 connecting the first sprocket 42 and the second sprocket 52. The provision of a chain transmission mechanism further increases the force that can be transmitted by the transmission booster 50, thereby further improving the movement stability and load-bearing capacity of the lifting platform 30.

[0066] like Figure 6 and Figure 9 As shown, in one embodiment, the vehicle-mounted device may further include a first position detection member 601 and a second position detection member 602. The first position detection member 601 is disposed at the highest position of the movement trajectory of the lifting platform 30. The second position detection member 602 is disposed at the lowest position of the movement trajectory of the lifting platform 30. When the lifting platform 30 is detected to be at the highest or lowest position, the drive device 40 can stop operating to prevent damage to the lifting platform 30.

[0067] Specifically, the first position detecting member 601 and the second position detecting member 602 can be proximity switches. The first position detecting member 601 is assembled at the upper portion of the fixed frame 60 , and the second position detecting member 602 is assembled at the lower portion of the fixed frame 60 .

[0068] In one embodiment, if Figure 6 As shown, the vehicle-mounted device also includes a stop block 603, and the lifting platform 30 may include a pin 33. The pin 33 is used to connect with the stop block 603 to secure the lifting platform 30 at the highest position of the motion trajectory. The stop block 603 is provided with a hole structure. When the lifting platform 30 reaches the highest position, the user can manually connect the stop block 603 with the hole structure of the stop block 603 to secure the lifting platform 30 for easy maintenance.

[0069] like Figure 6 As shown, the fixed frame 60 may include a first frame 61 and a second frame 62. The first frame 61 and the second frame 62 are connected. The first frame 61 is arranged horizontally. The second frame 62 is arranged vertically. The drive device 40 is assembled to the first frame 61, and the transmission force amplification device 50 is assembled to the second frame 62. Due to the horizontal arrangement of the first frame 61 and the vertical arrangement of the second frame 62, the fixed frame 60 is L-shaped as a whole, thereby improving the installation strength of the lifting platform 30, enhancing operational stability, and increasing the load capacity.

[0070] Please also refer to Figure 8 and Figure 9 As shown, the first frame 61 includes a pair of first rods 611, a pair of second rods 612, and a mounting plate 613. The pair of second rods 612 connects the ends of the pair of first rods 611. The mounting plate 613 connects the middle of the pair of first rods 611. The drive device 40 is fixed to the mounting plate 613.

[0071] The pair of first rods 611 and the pair of second rods 612 form a square frame structure. Because the mounting plate 613 connects the middle portions of the pair of first rods 611, the overall strength of the first frame 61 is enhanced. Furthermore, because the drive device 40 is secured to the mounting plate 613, the weight of the drive device 40 is evenly distributed across the first frame 61, enhancing the mounting strength of the drive device 40.

[0072] In one embodiment, a pair of first rods 611 extend relative to each other at their midsections to form a pair of supporting platforms 614, to which the mounting plate 613 is secured. The provision of the supporting platforms 614 enhances the mounting strength of the mounting plate 613, thereby enhancing the mounting strength of the drive device 40. Specifically, the supporting platforms 614 may be provided with a recessed platform 6141, into which the mounting plate 613 is fitted, further enhancing the mounting strength of the mounting plate 613.

[0073] In one embodiment, the mounting plate 613 is provided with a strip-shaped hole 615 and a fixing member 616. The fixing member 616 passes through the strip-shaped hole 615 and is connected to the first rod 611. The mounting plate 613 is capable of sliding relative to the fixing member 616 along the extension direction of the strip-shaped hole 614. Therefore, the relative position of the mounting plate 613 to the first frame 61 is variable. The mounting plate 613 can adapt its position to accommodate different mounting positions of the drive device 40, thereby enhancing the platformization and applicability of the vehicle-mounted device.

[0074] like Figure 10 As shown, a mounting bracket 617 and a first fixing bracket 618 are provided on the first frame 61. The mounting bracket 617 is used to install the lead screw 51. The first fixing bracket 618 is used to install the fixing frame 60 to the rear bucket.

[0075] like Figure 6 and Figure 10 As shown, the second frame 62 may include a third rod 621, a fourth rod 622, and a reinforcement rod 623. The third rods 621 are provided in pairs, arranged along the height direction and distributed on both sides of the lead screw 51. The fourth rod 622 connects the top ends of the pair of third rods 621, and the reinforcement rod 623 connects the middle portions of the pair of third rods 621, thereby providing greater strength to the second frame 62. One end of the lead screw 51 is assembled to the mounting bracket 617, and the other end is assembled to the middle portion of the fourth rod 622.
