[0002] The vehicle-mounted scales on the market mainly use column-type weighing sensors, which connect the two ends of multiple column-type weighing sensors to the frame and the bottom of the truck bed respectively to weigh the goods in the truck bed. When the vehicle is moving, especially when passing through bumpy roads, the vehicle-mounted scale will be subjected to additional stress, resulting in temporary fluctuations in the weighing readings. Under long-term influence, this repeated mechanical stress and vibration will have an adverse effect on the performance of the column-type weighing sensor and affect its service life.

[0003] Based on the above situation, the disassembly and assembly operation between the vehicle frame and the vehicle bed of the vehicle-mounted scale in the prior art is relatively difficult, and the vehicle-mounted scale cannot be effectively protected when the vehicle is driving in poor road conditions, thereby affecting the service life of the vehicle-mounted scale. Therefore, the present application provides a split-type vehicle-mounted weighing device. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a split-type vehicle-mounted weighing device, which can be folded up when there is no need to weigh the cargo on the vehicle, thereby effectively protecting the vehicle-mounted scale and avoiding the impact on the service life of the weighing device due to the bumps of the vehicle during travel. When it is needed, it can be quickly moved to a designated position, with good positioning performance and convenient operation.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A split vehicle-mounted weighing device is provided, comprising a base, a storage bin, a vertical platform and a scale seat, wherein the base is installed between the gap between the upper side of the wheel and the bottom of the frame, a sliding column is installed on the base for horizontal and transverse sliding, and the ends of a plurality of sliding columns are fixedly connected together by a side sliding arm, the storage bin is installed on the side sliding arm for horizontal and longitudinal sliding, the vertical platform is installed on the storage bin for vertical sliding, the scale seat is fixedly installed on the side of the vertical platform, a weighing platform is slidably installed on the weighing seat, and a pressure sensor is installed between the weighing platform and the weighing seat.

[0009] Furthermore, the storage bin is connected to the vertical platform via a movable connecting rod, one end of the movable connecting rod is rotatably connected to a rotating shaft on the storage bin, and the other end of the movable connecting rod is slidably engaged with a sliding groove on a side of the vertical platform.

[0010] Furthermore, two movable connecting rods are provided, and the two movable connecting rods are rotatably mounted on both ends of the storage bin respectively.

[0011] Furthermore, two slide grooves are provided on the side of the vertical platform, and the T-shaped columns at the ends of the two movable connecting rods are respectively embedded and slid in the two slide grooves, and the sides of the two movable connecting rods are against each other; when the weighing platform is stored in the storage bin, the two movable connecting rods are retracted in the storage bin in a crossed state.

[0017] 1. The split-type vehicle-mounted weighing device of the example of the utility model is respectively installed with a split-type vehicle-mounted weighing device on the upper side of multiple wheels of the vehicle body. When weighing is required, the storage bin and the scale seat are moved together to the upper front or upper rear of the wheel, and then the vertical platform is moved down so that the bottom of the scale seat contacts the ground.

[0033] Embodiment 1:

[0034] like Figure 1 and Figure 5 As shown, this embodiment provides a split-type vehicle-mounted weighing device, including a base 11, a storage bin 14, a vertical platform 21 and a scale base 31, the base 11 is installed between the gap between the upper side of the wheel and the bottom of the frame, a sliding column 12 is horizontally and laterally slidably installed on the base 11, and the ends of multiple sliding columns 12 are fixedly connected together by side sliding arms 13, the storage bin 14 is horizontally and longitudinally slidably installed on the side sliding arms 13, the vertical platform 21 is vertically slidably installed on the storage bin 14, the scale base 31 is fixedly installed on the side of the vertical platform 21, a scale platform 32 is slidably installed on the scale base 31, and a pressure sensor is installed between the scale platform 32 and the scale base 31.

[0035] Among them, the split-type vehicle-mounted weighing equipment of the present application is installed on a cargo flatbed trailer, a freight trailer, etc., and is used on a vehicle body with a large gap between the upper side of the wheel and the bottom of the frame.

[0036] The pressure sensor in the present application may use a bridge sensor and a column sensor that are commercially available.

[0037] like Figure 2 and Figure 4 As shown, the storage bin 14 is connected to the vertical platform 21 via a movable connecting rod 23, one end of the movable connecting rod 23 is rotatably connected to the rotating shaft 141 on the storage bin 14, and the other end of the movable connecting rod 23 is slidably engaged with the slide groove 22 on the side of the vertical platform 21.

[0038] A split-type vehicle-mounted weighing device is installed on each of the upper sides of the multiple wheels of the vehicle body. When the split-type vehicle-mounted weighing device of the present application is used to weigh the cargo on the vehicle:

[0039] First, the storage bin 14 is pulled out from the gap between the upper side of the wheel and the bottom of the frame, and the storage bin 14 is controlled to slide horizontally and longitudinally relative to the side sliding arm 13, so that the storage bin 14 and the scale seat 31 are moved to the upper front or upper rear of the wheel;

[0040] Afterwards, the vertical platform 21 is moved downward so that the bottom of the scale base 31 is in contact with the ground;

[0041] Finally, the vehicle body is controlled to travel forward or backward for a short distance, driving multiple wheels to rotate and move to the upper side of the scale platform 32 of multiple split-type vehicle-mounted weighing equipment to perform weighing operations. During this process, the storage bin 14 slides horizontally and longitudinally on the side sliding arm 13 to reset.

[0042] In addition, since the slide column 12 can slide horizontally relative to the base 11, and the storage bin 14 can slide horizontally relative to the side slide arm 13, the equipment can be easily stored in the gap between the upper side of the wheel and the bottom of the frame. When it needs to be deployed for use, it can be quickly moved to the designated position, with good positioning performance and convenient operation.

[0043] Furthermore, the connection between the two movable connecting rods 23 for the storage bin 14 and the vertical placement platform 21 is loose, and no force is transmitted, thereby not affecting the weighing process of the cargo on the vehicle.

[0044] To increase the smoothness of the wheel rotation to the upper side of the weighing platform 32, as Figure 5 As shown, a slope 33 is provided on one side of the scale base 31 , and the slope 33 is used to guide the wheel, thereby increasing the smoothness of the wheel rotating to the upper side of the scale platform 32 .

[0045] In order to increase the stability of the vertical movement of the vertical platform 21 relative to the storage bin 14, as Figure 3-4 As shown, two movable connecting rods 23 are provided, and the two movable connecting rods 23 are rotatably mounted on the two ends of the storage bin 14 , respectively. At this time, the other ends of the two movable connecting rods 23 can slide in the same slide groove 22 or different slide grooves 22 .

[0046] Among them, when two slide grooves 22 are provided on the side of the vertical platform 21, the T-shaped columns at the ends of the two movable links 23 are respectively embedded and slid in the two slide grooves 22, and the sides of the two movable links 23 are pressed against each other; when the scale platform 32 is stored in the storage bin 14, the two movable links 23 are retracted in the storage bin 14 in a cross state. In this state, the length of the movable links 23 can be set longer, increasing the vertical movement distance of the vertical platform 21 relative to the storage bin 14, so that it can be installed on the vehicle body with different wheel sizes, thereby improving the adaptability of the equipment.

[0047] Figure 1 , Figure 3 and Figure 4 The two movable connecting rods 23 are respectively in three states: fully retracted, half retracted, and extended.

[0048] like Figure 3-4 As shown, two limiting protrusions 24 are provided on the side of the vertical platform 21, and the limiting protrusions 24 can abut against the side surface of the movable link 23 to limit the maximum rotation angle of the movable link 23 to avoid the difficulty in retracting the movable link 23.

[0049] Embodiment 2:

[0050] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1-2 As shown, in this embodiment, C-shaped plug plates 15 are slidably installed on both sides of the storage bin 14, and the lower ends of the C-shaped plug plates 15 can abut against the bottom surface of the scale base 31 to limit the scale base 31 and stably store the scale base 31 in the storage bin 14 to prevent the scale base 31 from falling when weighing operation is not required.

[0051] The bottom edge of the C-shaped plug plate 15 is provided with an inclined surface, so that the lower end of the C-shaped plug plate 15 can easily abut against the bottom of the scale base 31 , thereby stably restricting the scale base 31 in the storage bin 14 .

[0052] To sum up, the weighing equipment of the present application is of split design and has the characteristic of being foldable. Compared with the floor scale fixed on the ground in the prior art, it has a smaller size, which reduces the manufacturing cost of the equipment and can be used whenever needed, which is very convenient. At the same time, the weighing equipment can be folded up when there is no need to weigh the cargo on the vehicle. Compared with the vehicle-mounted floor scale in the prior art, it can effectively protect the weighing equipment and prevent the bumps of the vehicle during movement from affecting the service life of the weighing equipment.

[0053] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
