[0049] In addition, it should be understood that although the present application is described in terms of embodiments, each embodiment does not necessarily contain only one independent technical solution, and the description of the present application is only for the sake of clarity, and those skilled in the art should consider the present application as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.

[0050] The existing part of the unmanned vehicle is equipped with a liquid storage tank for spraying medicine or watering crops. In the working state, the liquid storage tank needs to be fixed on the unmanned vehicle. The existing fixing method is to fixedly connect the fixing structure with the wall surface of the liquid storage tank. This method has high requirements for the wall thickness of the liquid storage tank at the connection position. In the case of insufficient structural strength of the liquid storage tank, the use of this fixing method is easy to cause damage to the liquid storage tank under heavy load, jolt and tilt.

[0051] To solve the above problems, referring to Figures 1-13 The present application provides a liquid storage tank mechanism, which comprises:

[0052] The liquid storage tank 200 is provided with a fixing hole 210 formed by the wall surface of the tank body of the liquid storage tank 200;

[0053] Mounting bracket 100 supports the liquid storage tank 200 at the bottom;

[0054] The mounting bracket 100 is provided with a support rod 300, which extends into the fixing hole 210 to limit and fix the liquid storage tank 200.

[0055] By providing a through fixing hole 210 on the liquid storage tank 200, the liquid storage tank 200 can be fixed by the support rod 300 extending into the fixing hole 210. On the other hand, the structural strength of the liquid storage tank 200 can be increased. The side wall of the fixing hole 210 can support the liquid storage tank 200 and prevent the liquid storage tank 200 from collapsing due to insufficient strength. At the same time, the inner wall of the fixing hole 210 has a surge protection function inside the liquid storage tank 200. When the liquid inside the liquid storage tank 200 forms a surge, it can be blocked by the fixing hole 210, thereby reducing the surge.

[0056] The liquid storage tank 200 described in this embodiment further includes a liquid storage tank cover and a liquid outlet connector. The top of the liquid storage tank 200 is provided with a liquid storage tank 200 inlet. The liquid storage tank cover can cooperate with the liquid storage tank 200 inlet to selectively open or close the liquid storage tank 200 inlet. The liquid storage tank 200 inlet is provided with external threads, and the liquid storage tank cover is provided with internal threads. The liquid storage tank cover can be screwed onto the liquid storage tank 200 inlet through threaded engagement. The bottom of the liquid storage tank 200 is provided with a liquid storage tank 200 outlet, and the liquid outlet connector is connected to the liquid storage tank 200 outlet.

[0057] The fixing hole 210 described in this application can take various forms. For example, in an optional embodiment, referring to... Figure 14 As shown, the fixing hole 210 is a blind hole. By setting a blind hole as the fixing hole 210, the side wall of the blind hole can be used for limiting and fixing, and the bottom wall of the blind hole can be used for support.

[0058] It is understood that the bottom wall of the aforementioned blind hole can be used for support and is not intended to limit this solution. In actual use, the depth of the blind hole can be set to be greater than the length of the support rod 300, so that the support rod 300 does not contact the bottom wall of the blind hole, which serves as the fixing hole 210, and only supports the liquid storage tank through the first surface 220.

[0059] For example, as another alternative implementation, refer to Figure 4 As shown, the fixing hole 210 is a through hole penetrating the liquid storage tank 200. The through hole allows the support rod 300 to be fully inserted, which can maximize the stability of the support rod when inserted into the fixing hole 210.

[0060] Specifically, refer to Figures 1-3As shown, the liquid storage tank 200 in the embodiment of the present application has a first surface 220 and a second surface 230 opposite to each other, and a containing space is formed between the first surface 220 and the second surface 230; the fixing hole 210 penetrates the liquid storage tank 200 in a direction perpendicular to the first surface 220, and connects the first surface 220 and the second surface 230, and the first surface 220 abuts against the mounting bracket 100.

[0061] As a preferred technical solution, the fixing hole 210 is a plurality of fixing holes 210, and the plurality of fixing holes 210 are uniformly distributed on the liquid storage tank 200.

[0062] In the case of a plurality of fixing holes 210, the structures of all the fixing holes 210 can be the same or different. For example, all the fixing holes 210 can be two specifications of fixing holes 210, and the fixing holes 210 of the same specification are uniformly and symmetrically distributed along the center line of the length direction of the liquid storage tank 200.

[0063] Preferably, referring to Figures 1-3 As shown, the four fixing holes 210 in the embodiment of the present application are of the same specification, and the four fixing holes 210 are symmetrically distributed in pairs along the center line of the length direction of the liquid storage tank 200.

[0064] It can be understood that the plurality of fixing holes 210 is not a limitation on the present solution, and in other embodiments of the present application, a solution of only one fixing hole 210 can also be used. When the fixing hole 210 is one, the fixing hole 210 needs to be arranged as much as possible at the geometric center position of the liquid storage tank 200, and the shape of the fixing hole 210 needs to be arranged as much as possible to avoid a structure of a revolution body. When the fixing hole 210 is one, arranging the fixing hole 210 at the geometric center position of the liquid storage tank 200 can ensure the force balance as much as possible when the liquid storage tank 200 is fixed through the fixing hole 210, avoid the problems of inclination of the liquid storage tank 200 caused by uneven force, deformation and damage of the fixing hole 210 caused by excessive load, and the like; at the same time, arranging the fixing hole 210 as a non-revolution body can avoid the rotation of the liquid storage tank 200 along the circumferential direction of the fixing hole 210.

[0065] Further, referring to Figure 3 As shown, the first surface 220 of the liquid storage tank 200 is provided with a mounting groove 221, the mounting bracket 100 is provided with a mounting rail 120 corresponding to the mounting groove 221, and the liquid storage tank 200 can move along the length direction of the mounting bracket 100 under the cooperation of the mounting groove 221 and the mounting rail 120.

[0066] In the present application, the predetermined positioning of the liquid storage tank 200 and the mounting bracket 100 is achieved by the cooperation of the mounting groove 221 and the mounting rail 120, so that the liquid storage tank 200 is clamped on the mounting bracket 100, is limited in the width direction of the mounting bracket 100, and can be adjusted in the installation position in the length direction of the mounting bracket 100, so that the fixing hole 210 on the liquid storage tank 200 corresponds to the installation position on the mounting bracket 100.

[0067] Specifically, referring to Figures 7-9 In the embodiment of the present application, the mounting rail 120 is two, which are arranged in the length direction of the mounting bracket 100 and parallel to each other.

[0068] Preferably, referring to Figure 13 As shown in the figure, the mounting rail 120 is provided with a T-shaped groove 121, and the groove bottom of the mounting groove 221 is provided with a T-shaped limiting block 222, which can be clamped in the T-shaped groove 121 and slide in the T-shaped groove 121. The mounting groove 221 is provided with a mounting hole 2211, and the T-shaped limiting block 222 is clamped in the mounting hole 2211. In some embodiments, the bottom wall of the T-shaped groove is provided with a through hole, and the bottom of the liquid storage tank is provided with a threaded hole, for example, a threaded hole is provided at the bottom of the T-shaped limiting block, which corresponds to the through hole of the bottom wall of the T-shaped groove. When mounting, a locking bolt can be screwed up from the bottom of the mounting bracket, and the locking bolt is sequentially inserted into the through hole of the T-shaped groove and the threaded hole of the T-shaped limiting block, so as to more stably fix the tank on the mounting bracket. In some embodiments, a nut can be pre-buried when the liquid storage tank is injection molded, so that the bottom of the liquid storage tank is provided with a nut after molding. When the liquid storage tank is placed on the mounting bracket, the locking bolt is inserted into the through hole of the mounting bracket and screwed into the nut of the liquid storage tank, so as to relatively fix the liquid storage tank and the mounting bracket.

[0069] Preferably, the T-shaped limiting block 222 is clamped in the mounting hole 2211 by the elastic part, and the elastic clamping mounting mode can provide a certain error space for the cooperation of the T-shaped block and the T-shaped groove 121, and also makes the disassembly and assembly of the T-shaped block and the mounting hole 2211 more convenient.

[0070] Referring to Figure 3 As shown in the figure, the fixing hole 210 has a hole side wall 223, and the position where the hole side wall 223 is connected with the first surface 220 and the second surface 230 is provided with a transition round corner 224.

[0071] The transition fillet 224 provided in the first surface 220 in the embodiment of the present application can be used for guiding when the support rod 300 is inserted into the fixing hole 210, and the gap between the liquid storage tank 200 and the support rod 300 at the transition fillet 224 can be filled with a buffer, so that a flexible connection is formed between the liquid storage tank 200 and the support rod 300, avoiding excessive gap between the two to cause shaking, and at the same time avoiding hard contact between the support rod 300 and the liquid storage tank 200, and causing damage to the liquid storage tank 200 due to friction when relative movement occurs.

[0072] As a further preferred technical solution, the embodiment of the present application further includes a buffer pad, which is sleeved on the support rod 300 and located between the fixing hole 210 and the support rod 300.

[0073] Filling the gap between the fixing hole 210 and the support rod 300 can effectively prevent the liquid storage tank 200 from shaking relative to the support rod 300. At the same time, the diameter of the fixing hole 210 can be greater than the diameter of the support rod 300, so as to facilitate the support rod 300 to pass into the fixing hole 210.

[0074] Specifically, referring to FIG. 1, Figure 9 The support rod 300 has a first connecting end 310 and a second connecting end 320 facing away from each other, a first limiting portion 311 is provided on the side of the first connecting end 310, and a second limiting portion 111 is provided on the mounting bracket 100. The support rod 300 is limited relative to the mounting bracket 100 by cooperation of the first limiting portion 311 and the second limiting portion 111.

[0075] In the embodiment of the present application, the first connecting end 310 extends below the first surface 220 for fixed connection with the mounting bracket 100. Specifically, referring to FIG. 1, Figures 5-11 The mounting bracket 100 is provided with a mounting clamp 110, and the support rod 300 is arranged between the mounting clamp 110 and the mounting bracket 100.

[0076] During assembly of the liquid storage tank 200 and the mounting bracket 100, the mounting clamp 110 is initially mounted on the cross beam, the liquid storage tank 200 is placed at a predetermined position on the mounting bracket 100, at this time, the clamping hole formed by the mounting clamp 110 and the mounting bracket 100 corresponds to the fixing hole 210 on the liquid storage tank 200, then the support rod 300 is arranged in the fixing hole 210 and the clamping hole, and the first limiting portion 311 and the second limiting portion 111 are positioned correspondingly, and then the connecting screw between the mounting clamp 110 and the mounting bracket 100 is locked, so that the mounting clamp is buckled on the support rod 300, and the first limiting portion 311 and the second limiting portion 111 are limited and matched.

[0077] Specifically, referring to Figure 9 In the embodiment of the present application, the first limiting part 311 is a limiting protrusion arranged on the first connecting end 310, and the second limiting part 111 is a limiting hole arranged on the mounting clamp 110.

[0078] It can be understood that the first limiting part 311 is a limiting protrusion and the second limiting part 111 is a limiting hole, which is not a limitation on the present application. In other embodiments, the first limiting part 311 can be arranged as a limiting hole, and the first limiting part 311 is arranged as a limiting protrusion matched therewith.

[0079] Further, the limiting protrusion can also adopt an elastic and scalable structure. In the case of adopting an elastic and scalable structure as a limiting protrusion, the limiting protrusion preferably adopts a spherical protrusion. In this structure, the support rod 300 can be disassembled in the state that the mounting clamp 110 and the mounting bracket 100 are locked, which can improve the replacement efficiency.

[0080] Optionally, a support protrusion is arranged on the first surface 220 at the middle of the length direction of the mounting bracket 100, and the mounting groove 221 is arranged on the support protrusion.

[0081] By arranging a support protrusion on the first surface 220 at the middle of the length direction of the mounting bracket 100, the length of the support protrusion is less than the length of the first surface 220 in the length direction of the mounting bracket 100, and arranging the mounting groove 221 on the support protrusion can reduce the length of the mounting groove 221, thereby reducing the contact area between the liquid storage tank 200 and the mounting bracket 100, which can effectively reduce the relative friction between the liquid storage tank 200 and the mounting bracket 100, so that the liquid storage tank 200 moves on the mounting bracket 100 in the length direction of the mounting bracket 100 more labor-saving.

[0082] Further, referring to Figures 1-3 As shown in the figure, the second surface 230 is provided with a support platform 231 on one side of the fixing hole 210, and the support platform 231 is provided with a connecting plate 400, one end of the connecting plate 400 is fixedly connected with the support platform 231, and the other end is fixedly connected with the support rod 300.

[0083] The support platform 231 provides a flat surface for installing the connecting plate 400, thereby ensuring the position accuracy between the connecting plate 400 and the support rod 300 after installation, and on the other hand, the thickness of the liquid storage tank 200 at this position can be increased, which facilitates the pre-setting of the connecting hole at this position, thereby facilitating the installation of the connecting plate 400.

[0084] Optionally, the cross-sectional area of the fixing hole 210 gradually decreases first and then increases in the direction from top to bottom. In this way, the assembly of the fixing hole 210 and the support rod 300 can be facilitated.

[0085] Preferably, a conical table is arranged outside the support rod 300 and cooperates with the inner wall of the fixing hole. Specifically, the conical table is arranged at the lower part of the support rod 300 in the embodiment, and the diameter of the conical table gradually increases from top to bottom, so that the conical table can be inserted into the fixing hole 210 and fit the transition round corner 224, thereby avoiding the shaking of the liquid storage tank 200 relative to the support rod 300, and supporting the liquid storage tank 200 from below by the support rod 300.

[0086] Meanwhile, the embodiment of the present application further provides an unmanned vehicle comprising the liquid storage tank mechanism as described above. In some embodiments, the mounting bracket 100 can be the vehicle body of the unmanned vehicle.

[0087] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the protection scope of the present application. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative labor, and these embodiments will fall within the protection scope of the present application.
