[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1-3 The diagram shown is a structural schematic of the vehicle-mounted water tank provided in this embodiment of the present invention. This vehicle-mounted water tank can be fixed to the roof rack of a vehicle and provides domestic water (e.g., for showering, car washing, etc.) for users. The vehicle-mounted water tank of this embodiment includes a rotomolded body 10, a booster pump 21, a switch assembly 30, a fixing assembly 40, a first water supply pipe (not shown in the figure), and a second water supply pipe 22. The rotomolded body 10 can hold domestic water. The booster pump 21, the first water supply pipe (not shown in the figure), and the second water supply pipe 22 are respectively installed on the rotomolded body 10. The switch assembly 30 is installed on the rotomolded body 10 through the fixing assembly 40.

[0027] The above-mentioned rotational molding body 10 is manufactured by rotational molding process and includes a water storage cavity (not shown in the figure), a water pump trough 12, a first mounting hole 14 and a second mounting hole 15. The rotational molding body 10 is loaded with domestic water through the water storage cavity. The water pump trough 12 is independent of the water storage cavity. The first mounting hole 14 and the second mounting hole 15 are respectively penetrated by the trough wall of the water pump trough 12 to the outer side wall of the rotational molding body 10.

[0028] In one embodiment of this utility model, the rotational molding body 10 is a flat strip, meaning that the length of the rotational molding body 10 (as indicated by arrow X) is much greater than its width (as indicated by arrow Y), for example, the length of the rotational molding body 10 is more than three times its width; the width of the rotational molding body 10 is greater than its height, for example, the width of the rotational molding body 10 is more than twice its height. Of course, in practical applications, the shape and size of the rotational molding body 10 can be designed as needed. In addition, the rotational molding body 10 may have several through holes 11 penetrating its upper and lower surfaces. By using fixing devices passing through the through holes 11, the rotational molding body 10 can be fixed to the roof rack.

[0029] A booster pump 21 is installed inside the pump tank 12, and its inlet end is connected to the water storage chamber via a first water supply pipe. The outlet end of the booster pump 21 is connected to a second water supply pipe 22, at least a portion of which extends through a second mounting hole 15 to the outer wall of the rotomolded body 10. This allows the booster pump 21 to output water stored in the water storage chamber when it is operating, increasing the water flow rate from the vehicle's water tank. Specifically, the end of the second water supply pipe 22 (exposed on the outer wall of the rotomolded body 10) can be connected to a water valve 50 (which can be connected to a shower head, etc., via a water pipe) to control the water flow. The booster pump 21, the first water supply pipe, the second water supply pipe, the structure of the booster pump 21 fixed to the pump tank 12, and the connection structure between the booster pump 21 and the first and second water supply pipes can all adopt conventional solutions in the art, and will not be described in detail here.

[0030] Combination Figure 4 , Figure 5 As shown, the fixing component 40 includes a first bracket 41 and a plurality of first fasteners 42, wherein the material strength of the first bracket 41 is greater than the material strength of the rotational molding body 10 (for example, the Young's modulus of the first bracket 41 is greater than the Young's modulus of the rotational molding body 10, and the tensile strength of the first bracket 41 is greater than the tensile strength of the rotational molding body 10), and the first bracket 41 has a wire through hole 411. Specifically, the first bracket 41 can be made of metal or engineering plastic with high hardness. The dimension of the first bracket 41 in at least one direction is larger than the dimension of the first mounting hole 14 in the same direction, so that the first bracket 41 can be engaged outside the opening of the first mounting hole 14 in that direction.

[0031] The switch assembly 30 is electrically connected to the booster water pump 21 and can be connected to an external power source (such as a vehicle power supply) to power the booster water pump 21. The switch assembly 30 controls the start and stop of the booster water pump 21, thereby controlling the water usage of the vehicle's water tank. The switch assembly 30 is located on the outer wall of the rotomolded body 10 and covers the first mounting hole 14 (i.e., the radial dimension of the switch assembly 30 is larger than the radial dimension of the first mounting hole 14). The first bracket 41 of the fixing assembly 40 is disposed on the wall of the water pump groove 12 with a wire through hole 411 opposite to the first mounting hole 14, and is locked and fixed to the switch assembly 30 via a first fastener 42 inserted into the first mounting hole 14. The switch assembly 30 is electrically connected to the booster water pump 21 through a cable passing through the first mounting hole 14 and the wire through hole 411 of the first bracket 41.

[0032] The vehicle-mounted water tank of this invention uses a first bracket 41 and a first fastener 42 to lock and fix the switch assembly 30 to the outer wall of the rotomolded body 10. Since the material strength of the first bracket 41 is greater than that of the rotomolded body 10, the stability of the switch assembly 30 is improved compared to directly fixing the switch assembly 30 to the rotomolded body 10. Even if the first bracket and the switch assembly 30 are damaged, they can be replaced without affecting the normal operation of the rotomolded body 10 and the booster pump 21.

[0033] In one embodiment of this utility model, to facilitate the installation of the booster pump 21 into the pump trough 12 and to facilitate the connection of the booster pump 21 with the first water supply pipeline and the second water supply pipeline, the opening of the pump trough 12 can be located on the top surface of the rotomolded body 10. Meanwhile, to prevent foreign objects from falling into the pump trough 12, a cover plate 13 can be fixed to the opening of the pump trough 12.

[0034] like Figure 4As shown, in one embodiment of this utility model, the first bracket 41 includes a first plate-shaped body, and the outer periphery of the first plate-shaped body is larger than the radial dimension of the first mounting hole 14. For example, when the cross-sections of the first plate-shaped body and the first mounting hole 14 are both rectangular, the length and width of the first plate-shaped body are larger than the length and width of the cross-section of the first mounting hole 14, respectively. The wire hole 411 can be formed by a through hole penetrating both surfaces of the first plate-shaped body, and the first plate-shaped body has a plurality of fixing holes 412, which respectively penetrate both surfaces of the first plate-shaped body.

[0035] The switch assembly 30 includes a second bracket 31, a power socket 33, and a switch device 32. The second bracket 31 includes a second plate-shaped body. Similar to the first plate-shaped body, the second bracket 31 has a dimension larger than the first mounting hole 14 in at least one direction, allowing the second bracket 31 to be engaged outside the opening of the first mounting hole 14 in that direction. Specifically, the outer periphery of the second plate-shaped body is larger than the radial dimension of the first mounting hole 14. For example, when both the cross-sections of the second plate-shaped body and the first mounting hole 14 are rectangular, the length and width of the second plate-shaped body are larger than the length and width of the cross-section of the first mounting hole 14, respectively. Furthermore, the material strength of the second plate-shaped body is greater than the material strength of the rotationally molded body 10. For example, the second plate-shaped body can be made of metal, engineering plastics with high hardness, etc. The power socket 33 is used to connect an external power supply and is electrically connected to the booster pump 21 via the switch device 32 and wires. The power supply to the booster pump 21 can be disconnected or connected via the switch device 32, thereby stopping or starting the booster pump 21. The power socket 33 and the switch 32 are respectively fixed on the second plate-shaped body. The specific structure of the power socket 33 and the switch 32, the structure of their fixing to the second plate-shaped body, and the electrical connection structure with the booster pump 21 can all adopt existing solutions in the field, and will not be described in detail here.

[0036] In one embodiment of this utility model, the first fastener 42 is composed of screws. Correspondingly, the inner side of the second plate-shaped body has a plurality of nut posts 311. These nut posts 311 are arranged axially along the first mounting hole 14, and these nut posts 311 are respectively opposite to the fixing holes 412 on the first plate-shaped body. The second bracket 31 is installed on the rotational molding body (the second plate-shaped body is attached to the outer side wall of the rotational molding body 10) by inserting the nut posts 311 into the first mounting hole 14. The screw passes through the fixing hole 412 of the first plate-shaped body from the water pump groove 12 and is locked to the nut posts 311 inserted into the first mounting hole 14. That is, the first plate-shaped body and the second plate-shaped body are respectively located at the two ends of the opening of the first mounting hole 14, and the rotational molding body is clamped by the screw, thereby realizing the locking and fixing of the switch assembly 30.

[0037] Because the materials of the first and second plate-shaped bodies have relatively high strength (greater than the material strength of the rotomolded body 10), the threads in the first bracket, the second bracket, and the nut column 311 are also stronger and less prone to damage, thus improving the stability of the switch assembly 30. Even if the first and second plate-shaped bodies are damaged, they can be replaced without affecting the normal operation of the rotomolded body 10 and the booster pump 21.

[0038] In one embodiment of this utility model, the inner side of the second plate-shaped main body has a plurality of nut posts 311 surrounding the power socket 33 and the switching device 32, and when the second bracket is installed onto the rotational molding main body, the plurality of nut posts 311 are respectively attached to the side wall of the first mounting hole 14 (along the axial direction of the first mounting hole 14). Thus, the second bracket can be positioned by means of the nut posts 311, which not only facilitates the installation of the second bracket, but also makes it easier for screws to be locked into the nut posts 311.

[0039] Specifically, the cross-section of the first mounting hole 14 is rectangular (the corners of the rectangle may be rounded), and correspondingly, the inner side of the second plate-shaped body has at least four nut posts 311 respectively attached to the four corners of the sidewall of the first mounting hole 14 (when the second plate-shaped body is attached to the outer sidewall of the rotationally molded body 10), such as Figure 6 As shown, each of the four nut posts 311 is attached to both side walls of the first mounting hole 14, which facilitates positioning. When the dimension of a certain radial side of the first mounting hole 14 is large, the number of nut posts 311 attached to that side can be increased.

[0040] like Figure 5 As shown, when the cross-section of the first mounting hole 14 is rectangular, the inner side of the first plate-shaped body may have at least four protrusions 413. When the second plate-shaped body is attached to the outer side wall of the rotational molding body 10, at least four protrusions 413 are respectively attached to the four corners of the side wall of the first mounting hole 14, which facilitates the installation and positioning of the first bracket and makes it easier for the screw to be locked into the nut post 311.

[0041] In one embodiment of this utility model, the inner side of the first plate-shaped main body may also have a plurality of protruding posts 414 formed by vertically extending from the top of the boss 413, and the fixing holes 412 respectively penetrate the protruding posts 414 along the axial direction (when the first plate-shaped main body is attached to the wall of the water pump tank 12, the protruding posts 414 are arranged along the axial direction of the first mounting hole 14). The protruding posts 414 can guide the insertion of screws, so that the screws can be inserted into the first mounting hole 14 along the axial direction of the first mounting hole 14, so that they can be smoothly locked into the nut post 411 on the second bracket 31.

[0042] In one embodiment of this utility model, the inner side of the first plate-shaped main body may also have multiple snap-fit ​​plates 415. These snap-fit ​​plates 415 are respectively perpendicular to the inner side of the first plate-shaped main body, and when the first bracket 41 is disposed at the first mounting hole 14 of the water pump groove 12, the multiple snap-fit ​​plates 415 are respectively attached to the four side walls of the first mounting hole 14. That is, the first bracket 41 can be snapped into the first mounting hole 14 by the multiple snap-fit ​​plates 415. In particular, in order to increase the structural strength of the snap-fit ​​plates 414, ribs can be added to the inner side of the snap-fit ​​plates 415 (i.e., the side facing away from the side wall of the first mounting hole 14).

[0043] like Figure 7 As shown, in one embodiment of this utility model, the outer wall of the rotational molding body 10 has a groove 16 surrounding the first mounting hole 14, and when the switch assembly 30 is installed on the rotational molding body 10, the switch assembly 30 is embedded in the groove 16, and a sealing gasket 34 is provided between the switch assembly 30 and the bottom of the groove 16. Through the above method, the sealing performance at the first mounting hole 14 can be improved.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
