Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric washing vehicle technology, and in particular to the water tank installation structure of an electric washing vehicle. Background Technology
[0002] Small electric washing vehicles offer good flexibility. Due to their lightweight design, quick start-up, and convenient parking, they can easily move between multiple points to perform small-scale washing operations. However, due to frequent starts and stops, the water in the tank will sway back and forth due to inertia, causing the tank to tend to move relative to the vehicle body. Therefore, the tank usually needs to be fixed. Common fixing methods often use tight-fitting connections such as bolts. However, the connection may wear down due to frequent shaking, leading to gaps and loosening, which makes the fixing effect on the tank ineffective for a long time. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a water tank installation structure for an electric washing vehicle, which can fix the water tank by insert-type limiting parts and alleviate the impact of water sloshing by balancing the impact force, thereby producing a long-term fixing effect on the water tank.
[0004] Technical solution: To achieve the above objectives, the water tank installation structure of the electric washing vehicle of this utility model includes a vehicle body, on which a water tank is placed. The water tank is constrained to the vehicle body by a limiting member. The limiting member can form a clamping force on the water tank to constrain the horizontal movement of the water tank on the vehicle body. The limiting member can also form a longitudinal pressure on the top of the water tank. The limiting member is also connected to the vehicle body through a balancing module. The balancing module can deform to generate a balancing force opposite to the impact force when the water in the water tank sloshes.
[0005] Furthermore, a cover is fixedly connected to the vehicle body; the balance module includes an elastic element, one end of which is fixedly connected to the inner wall of the cover, and the other end of which is connected to the horizontal extension in the middle of the limiting member. The elastic element can generate a front-to-back horizontal pulling force or a pushing force on the horizontal extension when it is subjected to force deformation.
[0006] Furthermore, the elastic element is a bent sheet, with one end of it bent to extend longitudinally away from the cover, and a pin is fixedly connected to the end. The pin can be inserted into the pin hole at the end of the horizontal extension, and the pin hole can provide horizontal support for the inserted part of the pin.
[0007] Furthermore, the limiting member can be longitudinally clamped relative to the water tank. The limiting member includes two opposing longitudinal structures, and each of the two longitudinal structures is provided with a plug at its lower part. The plug can be longitudinally inserted into a corresponding hole on the vehicle body. The hole can provide horizontal support for the inserted part of the plug, so that the two opposing longitudinal structures can form a clamping force on the water tank. The upper parts of the two opposing longitudinal structures are connected by a transverse structure, so that the transverse structure can form longitudinal pressure on the top of the water tank.
[0008] Furthermore, the two opposing longitudinal structures are respectively fitted to the front and rear tank surfaces of the water tank.
[0009] Furthermore, the two opposing longitudinal structures and the corresponding transverse structure constitute a limiting unit, the upper part of which is fixedly connected to the adapter plate, and the adapter plate is fixedly connected to the longitudinal extension at the top of the cover.
[0010] Furthermore, the adapter plate is fixedly connected to the rear side of the upper part of the limiting unit, and the adapter plate is in contact with the rear side of the longitudinal extension.
[0011] Furthermore, the upper end of the elastic member is fixedly connected to the rear side of the upper part of the limiting unit, and the corresponding horizontal extension member is fixedly connected to the middle part of the rear side of the limiting unit.
[0012] Beneficial effects: The water tank installation structure of this utility model for an electric washing vehicle constrains the water tank to the vehicle body through limiting components, and uses a balancing module on the limiting components to balance the impact force, thereby avoiding the problem of water tank loosening caused by frequent impacts; the limiting components generate clamping and pressing forces on the water tank through insertion, achieving the purpose of fixing the water tank, and this clamping and pressing force may weaken when subjected to impact and wear over a long period of time, but will not cause the water tank to loosen, thereby mitigating the impact of water sloshing and ensuring a long-term fixing effect on the water tank.

[0014] Figure 2 This is a schematic diagram showing the relationship and structure between the limiting component and the water tank. Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] As attached Figure 1-2The water tank mounting structure of the electric washing vehicle includes a vehicle body 1, on which a water tank 4 is placed. The water tank 4 is constrained to the vehicle body 1 by a limiting member 3. The limiting member 3 can form a clamping force on the water tank 4 to constrain the horizontal movement of the water tank 4 on the vehicle body 1. The limiting member 3 can also form a longitudinal pressure on the top of the water tank 4. The limiting member 3 is also connected to the vehicle body 1 through a balancing module. The balancing module can deform to generate a balancing force opposite to the impact force when the water in the water tank 4 sloshes.
[0017] This solution uses a limiting component to constrain the water tank to the vehicle body, preventing the water tank from sliding, jumping, or tipping over relative to the vehicle body. This allows the impact force generated when the water inside the tank shakes to be transmitted through the tank wall to the limiting component 3. The balancing module on the limiting component 3 then balances this impact force, thus avoiding the problem of the water tank loosening due to frequent impacts.
[0018] The vehicle body 1 is fixedly connected to the cover 2, and the water tank 4 is located in the inner cavity of the cover 2. By fixing the vehicle body 1 and the cover 2 together, the two form a whole. The water tank is located inside the cover and can be protected from sun exposure and rain erosion, thus obtaining good protection.
[0019] The balancing module includes an elastic element 5. One end of the elastic element 5 is fixedly connected to the inner wall of the housing 2, and the other end of the elastic element 5 is connected to the horizontal extension 34 in the middle of the limiting element 3. The elastic element 5 can generate a front-to-back horizontal pulling force or pushing force on the horizontal extension 34 when it is subjected to force. When the water moves back and forth in the water tank, the impact force generated by the water hitting the tank wall can be transmitted to the elastic element 5 through the horizontal extension 34. This causes the elastic element 5 to deform horizontally, thereby generating a force opposite to the impact force to buffer or even cancel the impact in one direction. This reduces the impact on the mating part of the plug and the socket, reduces the wear at the mating part, and thus increases the fixing effect.
[0020] Preferably, the elastic element 5 is a bent sheet, with its end furthest from the cover 2 bent to extend longitudinally, and a pin 51 fixedly connected to its end. The pin 51 can be inserted into a pin hole at the end of the horizontal extension 34, and the pin hole can provide horizontal support for the inserted portion of the pin 51. This ensures that the force generated by the deformation of the elastic element 5 and acting on the horizontal extension 34 is always in the horizontal direction, and its deformation is generated by the traction of water sloshing. Consequently, the resulting balancing force can be balanced with the main impact force generated by water sloshing, thereby eliminating most of the impact effects.
[0021] The limiting member 3 can be longitudinally engaged with the water tank 4. Preferably, the limiting member 3 includes two opposing longitudinal structures 31, and each of the two longitudinal structures 31 is provided with a plug 32 at its lower part. The plug 32 can be longitudinally inserted into the corresponding insertion hole on the vehicle body 1. The insertion hole can form a horizontal support force on the inserted part of the plug 32, so that the two opposing longitudinal structures 31 can form a clamping force on the water tank 4. The upper parts of the two opposing longitudinal structures 31 are connected by a transverse structure 33, so that the transverse structure 33 can form a longitudinal pressure on the top of the water tank 4.
[0022] In order to enable the two longitudinal structures to generate a certain clamping force on the vertical, in one embodiment, the two longitudinal structures and the transverse structure can be integrally formed, and the bending at the turning point generates a certain elastic restoring ability. By making the distance between the ends of the two longitudinal structures in the natural state slightly larger than the distance between the two corresponding holes, the lower ends of the two longitudinal structures tend to move closer to each other as the plug is inserted relative to the hole, thereby generating a certain clamping force on the water tank.
[0023] In another embodiment, the two longitudinal structures are made of square steel with stronger load-bearing capacity, while the transverse structure connected at the top is made of a sheet structure with a certain elastic restoring ability. The connection can be made by welding. When the plug is inserted into the socket, the elastic deformation ability of the transverse structure is mainly used to make the lower ends of the two longitudinal structures tend to move closer to each other, thereby generating a certain clamping force on the water tank.
[0024] Based on this, since common water tanks themselves have a certain degree of adaptability and deformation capability, even if the fitting of the plug and the socket is worn during long-term use, causing the lower ends of the two longitudinal structures to move away from each other by a certain distance, the clamping force will only weaken, but will not loosen, thus resulting in a more long-lasting fixing effect. In addition, more wear-resistant materials can be used for the parts of the plug and the socket to further improve the long-lasting effect of the fixing.
[0025] The two opposing longitudinal structures 31 are respectively attached to the front and rear surfaces of the water tank 4. Since the main sloshing trend of the water in the tank is back-to-back sloshing, the longitudinal structures can perform a better load-bearing function.
[0026] The two opposing longitudinal structures 31 and the corresponding transverse structure 33 constitute a limiting unit. The upper part of the limiting unit is fixedly connected to the adapter plate 6, and the adapter plate 6 is fixedly connected to the longitudinal extension 21 at the top of the cover 2. This allows the limiting member 3 to be fixedly connected to the inner wall of the cover 2. By inserting the limiting member relative to the vehicle body 1, the tank can be clamped and its movement in the horizontal plane can be restricted. Since the limiting member is fixedly connected to the cover, the relative position of the limiting member and the vehicle body 1 will not change, thus preventing the plug from easily sliding out of the insertion hole. Based on this, the transverse structure 33 can stably press the water tank onto the vehicle body, preventing the water tank from jumping off the vehicle body when the road surface is bumpy.
[0027] Multiple limiting units are arranged horizontally. This increases the constraint force on the water tank, and the number of limiting units can be selected according to the size of the water tank. It also ensures that the constraint positions of the multiple limiting units relative to the water tank are evenly distributed, guaranteeing the force balance of the entire tank.
[0028] The upper parts of the multiple limiting units are fixedly connected to the adapter plate 6, and the adapter plate 6 is fixedly connected to the longitudinal extension 21 on the top of the cover 2. The adapter plate 6 and the longitudinal extension 21 fit together front and back. This allows the multiple limiting units to form a whole, while the vehicle body forms a horizontal constraint force on the lower part of the limiting member, and the cover 2 forms a horizontal constraint force on the upper part of the limiting member. This ensures that the water tank will not tilt back and forth, thereby reducing the relative sliding friction between the plug and the socket, maintaining a static friction relationship between the plug and the socket as much as possible, and using the reaction force generated by the elastic element to balance the impact force generated when the water sloshes. This keeps the relative force between the plug and the socket in the horizontal direction within a reasonable range, especially in the front and back direction, thereby reducing the wear phenomenon caused by static friction and prolonging the fixing effect on the water tank.
[0029] The adapter plate 6 is fixedly connected to the rear side of the upper part of the limiting unit, and the adapter plate 6 is abutted against the rear side of the longitudinal extension member 21. Considering that electric vehicles accelerate quickly from a standstill but the acceleration process is relatively gradual, the impact effect of water sloshing caused by sudden braking is stronger. Preferably, the adapter plate 6 is fixedly connected to the rear side of the upper part of the limiting unit, and the adapter plate 6 is abutted against the rear side of the longitudinal extension member 21. This makes the limiting member more effective in restricting the tendency of the water tank to tilt forward.
[0030] Of course, the sloshing of water not only affects the fixation of the water tank, but also has a certain impact on the connection of other parts of the vehicle body. In this solution, the elastic component 5 also forms an elastic connection between the limiting component and the cover, which can prevent the impact force generated by the sloshing of water from affecting the fixed connection between the cover and the vehicle body.
[0031] The upper end of the elastic element 5 is fixedly connected to the rear side of the upper part of the limiting unit, and the corresponding horizontal extension 34 is fixedly connected to the middle part of the rear side of the limiting unit. When the limiting unit is inserted relative to the vehicle body, its longitudinal structure located at the rear side of the water tank tends to swing forward. This causes the horizontal extension 34 to slightly pull the end of the elastic element 5 forward, thereby storing a certain amount of elastic potential energy. This allows a small horizontal backward pulling force to be generated on the middle part of the water tank when no water sloshing occurs. Considering that the longitudinal constraint force of the cover on the limiting element is biased towards the rear part of the limiting element, its front part tends to slide upward, which in turn causes the water tank to tend to tilt backward. This tendency can be overcome by balancing the horizontal pulling force in the middle.
[0032] Preferably, each of the limiting units is provided with a corresponding elastic element 5, and the upper ends of the multiple elastic elements 5 are fixedly connected to the adapter plate 6, and the corresponding limiting units and elastic elements 5 are respectively fixedly connected to both sides of the adapter plate 6.
[0033] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
