Description

Technical Field

[0001] This utility model relates to the field of unmanned vehicle floor sealing technology, and in particular to a sealing structure, an unmanned vehicle floor, and an unmanned vehicle. Background Technology

[0002] In the operation of autonomous logistics vehicles, the cargo box of the vehicle needs to withstand frequent risks of fluid intrusion, such as manual washing and cleaning, and rainwater erosion. In particular, when the washing water flows through the inner wall of the cargo box and seeps into the floor of the autonomous vehicle, it can easily flow into the electrical compartment (including core components such as the drive controller and battery management system) through the assembly gaps of the floor, causing short circuit failure or corrosion of metal parts. Therefore, a waterproof sealing solution needs to be designed to deal with the above problems.

[0003] The current mainstream solution is to use a sponge pad to fill the gap between the base plate and the electrical compartment. This material has the ability to deform elastically, but it needs to be precisely cut and a uniform pre-tightening force needs to be applied. It is inconvenient to install and is prone to gaps due to insufficient compression or fatigue cracking due to excessive compression, which leads to a decrease in sealing ability. At the same time, when the sponge pad is saturated with water, it will form a water pool effect, affecting the overall sealing effect.

[0004] Therefore, a sealing structure is urgently needed to solve the above-mentioned technical problems. Utility Model Content

The sealing assembly includes: a snap-fit ​​member and an elastic deformation member arranged along a first direction; the snap-fit ​​member snaps onto the annular baffle; one end of the elastic deformation member is connected to the snap-fit ​​member, and the other end abuts against the upper chassis; the first direction is a vertical direction; the snap-fit ​​member includes a first flexible portion and a first blocking portion and a second blocking portion respectively connected to the elastic deformation member; the first blocking portion abuts against the lower chassis; in a second direction, the first blocking portion and the second blocking portion are respectively located on both sides of the annular baffle; the first flexible portion is disposed between the first blocking portion and the second blocking portion and abuts against the annular baffle; the second direction is at an angle to the first direction.

[0008] In some embodiments, the first flexible portion includes a first flexible sub-portion and a second flexible sub-portion; one end of the first flexible sub-portion is connected to the first blocking portion, and the other end abuts against the annular baffle; one end of the second flexible sub-portion is connected to the second blocking portion, and the other end abuts against the annular baffle.

[0009] In some embodiments, the first flexible sub-part is inclined in a direction away from the lower base plate; and / or, the second flexible sub-part is inclined in a direction away from the lower base plate.

[0010] In some embodiments, the angle between the first flexible sub-part and the second direction is a first angle, and the angle range of the first angle is 10° to 45°; and / or, the angle between the second flexible sub-part and the second direction is a second angle, and the angle range of the second angle is 10° to 45°.

[0011] In some embodiments, the number of the first flexible portions is multiple; the multiple first flexible portions are arranged at intervals along the first direction.

[0012] In some embodiments, among the plurality of first flexible portions, the distance between the first flexible portion away from the lower base plate and the lower base plate in the first direction is less than or equal to the dimension of the annular baffle in the first direction.

[0013] In some embodiments, the sealing structure further includes a second flexible portion, one end of which is connected to the side of the elastic deformable member away from the snap-fit ​​member, and the other end abuts against the upper base plate; the second flexible portion is inclined in a direction away from the electrical compartment.

[0014] In some embodiments, the angle between the second flexible portion and the first direction is a third angle, and the angle range of the third angle is 10° to 45°.

[0015] On the other hand, this utility model provides an unmanned vehicle chassis, which includes an upper chassis, a lower chassis, a support frame connected to the upper chassis and the lower chassis respectively, and a sealing structure as described in any of the above embodiments; the electrical compartment is disposed between the lower chassis and the upper chassis; a flow guide groove is provided around the sealing structure; the support frame has a water inlet and a water outlet; the water inlet is connected to the flow guide groove; and the water outlet is connected to the external environment.

[0016] On another front, this utility model provides an unmanned vehicle, which includes a modular superstructure and an unmanned vehicle chassis as described in the above embodiments; the modular superstructure is installed on the unmanned vehicle chassis.

[0017] The beneficial effects of this utility model are:

[0018] On one hand, this utility model provides a sealing structure, which involves setting an annular baffle surrounding the electrical compartment on the lower base plate of the unmanned vehicle chassis, and setting a sealing component that is adapted to and can be snapped onto the annular baffle. The sealing component is configured as a snap-fit ​​member and an elastic deformation member arranged along a first direction. The snap-fit ​​member is snapped onto the annular baffle, and one end of the elastic deformation member is connected to the snap-fit ​​member, while the other end abuts against the upper base plate. At the same time, the snap-fit ​​member is configured as a first blocking part and a second blocking part located on both sides of the annular baffle, wherein the first blocking part abuts against the lower base plate, and a first flexible part is disposed between the first blocking part and the second blocking part and abuts against the annular baffle. This design allows for easy installation and maintenance when the sealing structure needs to be installed between the lower and upper base plates of the autonomous vehicle. The annular baffle can be installed on the lower base plate first, and then the sealing component can be snapped onto the annular baffle. Subsequent replacement of the sealing component is also straightforward; simply remove the existing sealing component from the annular baffle and then re-snap the new one onto it. Furthermore, because the sealing component is structured as a snap-fit ​​element and an elastically deformable element that abuts against the upper base plate, there is no need to separately adjust the gap between the upper base plate and the electrical compartment when installing the upper base plate. The elastically deformable element can utilize its own ability to deform elastically. The sealant always abuts against the upper base plate, thus fully filling the gap between the upper base plate and the electrical compartment, ensuring high sealing performance and further facilitating installation by workers. In addition, in the above-mentioned sealing mechanism, the elastic deformable element can be used to tightly abut against the upper base plate to prevent liquid from entering the electrical compartment; the annular baffle can be used to a certain extent to prevent liquid from entering the electrical compartment; the first blocking part abuts against the lower base plate to prevent liquid from entering the electrical compartment; and the first flexible part in the snap-fit ​​component abuts against the annular baffle to prevent liquid from bypassing the annular baffle and entering the electrical compartment. The cooperation of multiple components greatly improves the sealing performance of the above-mentioned sealing structure.

[0019] On the other hand, this utility model provides an unmanned vehicle chassis plate that has all the features of the aforementioned sealing structure, and its beneficial effects are the same as those of the aforementioned sealing structure, which will not be described again here. Furthermore, by setting a guide channel around the aforementioned sealing structure, and providing an inlet and an outlet in the support frame; connecting the inlet to the guide channel; and connecting the outlet to the external environment, when liquid accumulates around the sealing structure, the guide channel in the unmanned vehicle chassis plate can guide the accumulated liquid into the support frame, and the outlet on the support frame can discharge the liquid to the external environment. This ensures that no liquid accumulates inside the unmanned vehicle chassis plate, thereby preventing long-term immersion in liquid and corrosion of the metal parts in the chassis plate, and improving the service life of the unmanned vehicle chassis plate.

[0020] On the other hand, this utility model provides an unmanned vehicle that possesses all the features of the aforementioned unmanned vehicle chassis, and its beneficial effects are the same as those of the aforementioned unmanned vehicle chassis, which will not be described again here. In addition, by adopting the aforementioned unmanned vehicle chassis, it is convenient for staff to wash and clean the unmanned vehicle, and at the same time, it enables the unmanned vehicle to operate in rainy weather, improving the unmanned vehicle's weather adaptability.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Combination Figures 1 to 4 As shown, this embodiment discloses a sealing structure 40. The sealing structure 40 is used to seal the electrical compartment 50 in the unmanned vehicle floor 100, which includes an upper floor plate 10 and a lower floor plate 20. The sealing structure 40 includes an annular baffle 1 and a sealing assembly 2.

[0037] like Figure 1As shown, the aforementioned annular baffle 1 is disposed on the lower base plate 20 of the unmanned vehicle's floor 100 and surrounds the electrical compartment 50. In other words, the annular baffle 1 is a plate-like structure with its ends connected, and the electrical compartment 50 is located inside this plate-like structure. Alternatively, the orthographic projection of the electrical compartment 50 in the first direction X1 is located within the inner contour of the orthographic projection of the annular baffle 1 in the first direction X1. This allows the annular baffle 1 to surround the electrical compartment 50, thereby achieving a water-blocking effect. The connection between the annular baffle 1 and the lower base plate 20 is a fixed connection (e.g., welding).

[0038] Combination Figure 1 , Figure 3 , Figure 4 As shown, the sealing component 2 is adapted to the annular baffle 1, and the sealing component 2 can be snapped into the annular baffle 1. It is easy to understand that the adaptation of the sealing component 2 to the annular baffle 1 means that the shape and size of the orthographic projection of the sealing component 2 in the first direction X1 are the same as the shape and size of the orthographic projection of the annular baffle 1 in the first direction X1. In other words, the sealing component 2 is also an annular structure, and the shape and size of this annular structure are the same as the shape and size of the annular baffle 1.

[0039] like Figure 4 As shown, the sealing assembly 2 includes a snap-fit ​​member 21 and an elastic deformation member 22 arranged along a first direction X1. The snap-fit ​​member 21 snaps onto the annular baffle 1, and one end of the elastic deformation member 22 is connected to the snap-fit ​​member 21, while the other end abuts against the upper base plate 10. Here, the first direction X1 is the vertical direction. Specifically, taking... Figure 4 Taking the shown perspective as an example, the lower end of the aforementioned annular baffle 1 is connected to the lower base plate 20, and a snap-fit ​​member 21 is engaged at the upper end of the annular baffle 1. An elastic deformation member 22 is connected to the upper end of the snap-fit ​​member 21, and the upper end of the elastic deformation member 22 abuts against the upper base plate 10. The material of the aforementioned elastic deformation member 22 can be general synthetic rubber (e.g., fluororubber) or thermoplastic elastomer (e.g., styrene). The connection method between the aforementioned snap-fit ​​member 21 and the elastic deformation member 22 is, for example, adhesive bonding, or the two are integrally molded structures. It is easy to understand that both the aforementioned snap-fit ​​member 21 and the elastic deformation member 22 are annular structures.

[0040] like Figure 4As shown, the aforementioned snap-fit ​​member 21 includes a first flexible portion 211 and a first blocking portion 212 and a second blocking portion 213 respectively connected to the elastic deformation member 22. The first blocking portion 212 abuts against the lower base plate 20. In the second direction X2, the first blocking portion 212 and the second blocking portion 213 are respectively located on both sides of the annular baffle 1, where the second direction X2 is set at an angle to the first direction X1, for example, 90°. It is easy to understand that "located on both sides of the annular baffle 1" means that the first blocking portion 212 and the second blocking portion 213 are respectively located on the side of the annular baffle 1 closer to the electrical compartment 50 (or the inner side) and the side of the annular baffle 1 away from the electrical compartment 50 (or the outer side). The aforementioned first flexible portion 211 is disposed between the first blocking portion 212 and the second blocking portion 213 and abuts against the annular baffle 1. The material of the first flexible portion 211 is, for example, silicone rubber.

[0041] Therefore, the sealing structure 40 provided in this embodiment is provided by setting an annular baffle 1 surrounding the electrical compartment 50 on the lower base plate 20 of the unmanned vehicle base plate 100, and setting a sealing component 2 that is adapted to and can be snapped onto the annular baffle 1. The sealing component 2 is configured as a snap-fit ​​member 21 and an elastic deformation member 22 arranged along the first direction X1. The snap-fit ​​member 21 is snapped onto the annular baffle 1, and one end of the elastic deformation member 22 is connected to the snap-fit ​​member 21, and the other end abuts against the upper base plate 10. At the same time, the snap-fit ​​member 21 is configured as a first blocking part 212 and a second blocking part 213 located on both sides of the annular baffle 1, wherein the first blocking part 212 abuts against the lower base plate 20, and a first flexible part 211 is disposed between the first blocking part 212 and the second blocking part 213 and abuts against the annular baffle 1. This design allows for easy installation and maintenance when the sealing structure 40 needs to be installed between the lower base plate 20 and the upper base plate 10 of the unmanned vehicle. The annular baffle 1 can be installed on the lower base plate 20 first, and then the sealing component 2 can be snapped onto the annular baffle 1. Furthermore, replacing the sealing component 2 only requires removing the old sealing component 2 from the annular baffle 1 and then re-snap the new sealing component 2 onto the annular baffle 1. Additionally, because the sealing component 2 is structured as a snap-fit ​​element 21 and an elastically deformable element 22 that abuts against the upper base plate 10, there is no need to separately adjust the gap between the upper base plate 10 and the electrical compartment 50 when installing the upper base plate 10. The elastically deformable element 22 can utilize its own elastic deformation properties. It always abuts against the upper base plate 10, thereby fully filling the gap between the upper base plate 10 and the electrical compartment 50, ensuring high sealing performance and further facilitating installation by workers; in addition, in the above-mentioned sealing mechanism, the elastic deformation member 22 can be used to tightly abut against the upper base plate 10 to prevent liquid from entering the electrical compartment 50, the annular baffle 1 can be used to a certain extent to prevent liquid from entering the electrical compartment 50, the first blocking part 212 abuts against the lower base plate 20 to prevent liquid from entering the electrical compartment 50, and the first flexible part 211 provided in the snap-fit ​​member 21 abuts against the annular baffle 1 to prevent liquid from bypassing the annular baffle 1 and entering the electrical compartment 50. The cooperation of multiple components greatly improves the sealing performance of the above-mentioned sealing structure 40.

[0042] In some embodiments, such as Figure 4 As shown, the first flexible portion 211 includes a first flexible sub-portion 2111 and a second flexible sub-portion 2112. One end of the first flexible sub-portion 2111 is connected to the first blocking portion 212, and the other end abuts against the annular baffle 1; one end of the second flexible sub-portion 2112 is connected to the second blocking portion 213, and the other end abuts against the annular baffle 1. That is, with... Figure 4Taking the shown perspective as an example, the first flexible sub-part 2111 is disposed between the first blocking part 212 and the annular baffle 1 (i.e., on the left side of the annular baffle 1). The left end of the first flexible sub-part 2111 is connected to the first blocking part 212 (the connection method between the two is, for example, bonding, or the two are integrally formed structures). The right end of the first flexible sub-part 2111 abuts against the left side wall of the annular baffle 1. The second flexible sub-part 2112 is disposed between the second blocking part 213 and the annular baffle 1 (i.e., on the right side of the annular baffle 1). The right end of the second flexible sub-part 2112 is connected to the second blocking part 213 (the connection method between the two is, for example, bonding, or the two are integrally formed structures). The left end of the second flexible sub-part 2112 abuts against the right side wall of the annular baffle 1. With this configuration, a multi-level seal can be formed using the first flexible sub-part 2111 and the second flexible sub-part 2112. That is, even if liquid seeps through the first flexible sub-part 2111, the second flexible sub-part 2112 can still play a sealing role, preventing liquid from entering the electrical compartment 50 and further improving the sealing performance of the sealing structure 40.

[0043] In some embodiments, combined with Figure 4 , Figure 5 As shown, the first flexible sub-part 2111 is inclined in a direction away from the lower base plate 20, that is, with Figure 5 Taking the shown viewpoint as an example, the first flexible sub-part 2111 is inclined upwards. And / or, the aforementioned second flexible sub-part 2112 is inclined away from the lower base plate 20, that is, with Figure 5 Taking the illustrated viewpoint as an example, the second flexible sub-part 2112 is inclined upwards. It is easy to understand that "and / or" here includes the following three cases: only the first flexible sub-part 2111 is inclined upwards, only the second flexible sub-part 2112 is inclined upwards, and both the first flexible sub-part 2111 and the second flexible sub-part 2112 are inclined upwards. Those skilled in the art can flexibly configure it according to actual usage requirements.

[0044] With the above arrangement, a certain angle can be formed between the first flexible sub-part 2111 and / or the second flexible sub-part 2112 and the side wall of the annular baffle 1, which facilitates the snap-fit ​​member 21 of the sealing assembly 2 to snap onto the annular baffle 1, further facilitating the installation of the sealing assembly 2 by the operator; at the same time, with the above arrangement, when the first flexible part 211 abuts against the annular baffle 1, the contact area between the first flexible sub-part 2111 and / or the second flexible sub-part 2112 and the side wall of the annular baffle 1 can be increased, which can further improve the sealing performance of the sealing assembly 2 to a certain extent.

[0045] In some embodiments, the angle between the first flexible sub-part 2111 and the second direction X2 is a first included angle α1, which ranges from 10° to 45°. For example, the first included angle α1 is 10°; or 15°; or 27.5°; or 30°; or 45°.

[0046] And / or, the angle between the second flexible sub-part 2112 and the second direction X2 is a second included angle α2, and the angle range of the second included angle α2 is 10° to 45°. For example, the angle of the second included angle α2 is 10°; or, the angle of the second included angle α2 is 15°; or, the angle of the second included angle α2 is 27.5°; or, the angle of the second included angle α2 is 30°; or, the angle of the second included angle α2 is 45°.

[0047] With the above settings, the angle between the first flexible sub-part 2111 and / or the second flexible sub-part 2112 and the second direction X2 (i.e., the outer wall of the annular baffle 1) can be in a suitable range, taking into account the ease of installation, ease of disassembly and sealing of the sealing assembly 2.

[0048] In some embodiments, combined with Figure 4 , Figure 5 As shown, there are multiple first flexible portions 211, which are arranged at intervals along the first direction X1. For example, there are two first flexible portions 211, arranged at intervals along the first direction X1. In other words, two first flexible sub-parts 2111 are arranged at intervals along the first direction X1 between the first blocking portion 212 and the annular baffle 1, and two second flexible sub-parts 2112 are arranged at intervals along the first direction X1 between the second blocking portion 213 and the annular baffle 1. Of course, the number of first flexible portions 211 can also be three, four, or five, and those skilled in the art can flexibly configure them according to actual usage requirements. This configuration creates more levels of sealing in the sealing structure 40, further improving the sealing performance of the sealing structure 40.

[0049] In some embodiments, when there are multiple first flexible portions 211, among the multiple first flexible portions 211, the distance between the first flexible portion 211 furthest from the lower base plate 20 and the lower base plate 20 in the first direction X1 is less than or equal to the dimension of the annular baffle 1 in the first direction X1. In other words, with Figure 6Taking the shown viewpoint as an example, the distance between the uppermost first flexible part 211 and the lower base plate 20 is less than or equal to the height of the annular baffle 1. This arrangement ensures that all the first flexible parts 211 can abut against the annular baffle 1, thereby ensuring the sealing performance of the sealing assembly 2.

[0050] In some embodiments, combined with Figure 4 , Figure 6 As shown, the sealing structure 40 further includes a second flexible portion 3. One end of the second flexible portion 3 is connected to the side of the elastic deformable member 22 away from the snap-fit ​​member 21, and the other end abuts against the upper base plate 10. The second flexible portion 3 is inclined away from the electrical compartment 50. That is, with Figure 4 Taking the shown perspective as an example, the lower end of the second flexible part 3 is connected to the upper side of the elastic deformation member 22, and the upper end of the second flexible part 3 abuts against the upper base plate 10. At the same time, the second flexible part 3 is tilted to the left or right (when the electrical compartment 50 is located to the right of the second flexible part 3, the second flexible part 3 is tilted to the left; when the electrical compartment 50 is located to the left of the second flexible part 3, the second flexible part 3 is tilted to the right). With this arrangement, a further seal can be achieved between the elastic deformation member 22 and the upper base plate 10, further improving the sealing performance of the above-mentioned sealing structure 40.

[0051] In some embodiments, the angle between the second flexible portion 3 and the first direction X1 is a third angle α3, which ranges from 10° to 45°. For example, the angle α3 is 10°; or 15°; or 27.5°; or 30°; or 45°. This arrangement ensures that the angle between the second flexible portion 3 and the first direction X1 is within a suitable range, thereby improving the sealing performance of the sealing assembly 2.

[0052] On the other hand, this embodiment provides an unmanned vehicle chassis 100. Combined with... Figure 1 , Figure 7 , Figure 8As shown, the unmanned vehicle chassis 100 includes an upper chassis 10, a lower chassis 20, a support frame 30 connected to the upper chassis 10 and the lower chassis 20 respectively, and a sealing structure 40 as described in any of the embodiments above. The electrical compartment 50 is disposed between the lower chassis 20 and the upper chassis 10. The support frame 30 is, for example, a frame structure formed by combining multiple rectangular tubes, and the upper chassis 10 and the lower chassis 20 are connected to the support frame 30 by, for example, welding or bolting. A flow guide 60 is provided around the sealing structure 40, that is, the flow guide 60 is an annular groove structure; the support frame 30 has an inlet 301 and an outlet 302, wherein the inlet 301 is connected to the flow guide 60, and the outlet 302 is connected to the external environment.

[0053] With the above-mentioned configuration, when external liquid enters the space between the upper base plate 10 and the lower base plate 20 through the assembly gap between the upper base plate 10 and the support frame 30, the sealing structure 40 can firstly prevent the liquid from entering the electrical compartment 50, thus avoiding short circuit failure of electrical components or corrosion of metal parts inside the electrical compartment 50; secondly, when liquid accumulates around the sealing structure 40, the guide channel 60 provided in the unmanned vehicle base plate 100 can be used to guide the accumulated liquid into the support frame 30, and the liquid can be discharged to the external environment through the outlet 302 opened on the support frame 30, ensuring that there is no liquid accumulation inside the unmanned vehicle base plate 100, thereby preventing the unmanned vehicle base plate 100 from being immersed in liquid for a long time, which would lead to corrosion of the metal parts in the unmanned vehicle base plate 100 and improve the service life of the unmanned vehicle base plate 100.

[0054] It is easy to understand that the number of water inlets 301 in the aforementioned support frame 30 can be set to multiple, and the positions of the multiple water inlets 301 are evenly distributed in the support frame 30. For example, the aforementioned support frame 30 has a rectangular structure, and the number of water inlets 301 is four. The four water inlets 301 are evenly distributed on two opposite sides of the rectangular structure, that is, two water inlets are evenly spaced on each opposite side of the rectangular structure. With this arrangement, the efficiency of introducing the liquid accumulated inside the guide channel 60 into the support frame 30 can be improved.

[0055] Similarly, the number of water outlets 302 in the aforementioned support frame 30 can also be set to multiple, with the multiple water outlets 302 evenly distributed throughout the support frame 30. This arrangement can improve the efficiency of liquid discharge from inside the support frame 30 to the external environment.

[0056] On another front, this embodiment provides an unmanned vehicle. The unmanned vehicle includes a modular superstructure and an unmanned vehicle chassis 100 as described in the embodiments above. The modular superstructure is mounted on the unmanned vehicle chassis 100, and the modular superstructure is, for example, a cargo box. This arrangement facilitates cleaning and washing of the unmanned vehicle by staff, and also enables the unmanned vehicle to operate in rainy weather, improving its weather adaptability.
