Technical Field

[0001] The invention belongs to the technical field of intelligent detection, and in particular relates to a non-contact vehicle light and heavy load detection device. Background Art

[0002] In mining areas, mine cars are prone to side slips and road collapse on rugged roads. Overloading vehicles will increase the damage to the road surface, and for every ton of overload, the braking distance will be extended by one meter. Overloading vehicles will reduce the braking and steering performance of vehicles. Therefore, the load of mine cars must be strictly controlled.

[0003] At present, a contact detection device is commonly used to detect the weight of a mine car. However, the contact detection device will be damaged when the mine car is overloaded, which increases the detection cost. In addition, the contact detection device is inconvenient to carry. Summary of the invention

[0004] In order to solve the above problems existing in the related art, the present invention provides a non-contact vehicle light and heavy load detection device. The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0005] The present invention provides a non-contact vehicle light or heavy load detection device, which is arranged on a vehicle with a retractable bucket component (3), wherein the retractable bucket component (3) is retracted in a direction perpendicular to the ground as the objects loaded in the bucket of the vehicle increase or decrease, and the device comprises:

[0006] A magnetic member (1), a Hall sensor (2), a movable rocker (4) and a detection component (5);

[0007] One end of the movable rocker (4) is arranged on the retractable part (3) of the truck bucket, and when the retractable device (3) of the truck bucket is extended and retracted in a direction perpendicular to the ground, the movable rocker (4) is driven to move up and down in a direction perpendicular to the ground;

[0008] The magnetic member (1) is arranged at an end of the movable rocker (4) that is not connected to the retractable member (3) of the truck bucket, and is at a first preset distance from the ground when no object is loaded in the truck bucket;

[0009] The Hall sensor (2) is arranged on a side of the front wheel axle of the vehicle close to the cab chassis and is electrically connected to the detection component (5); the Hall sensor (2) is at a second preset distance from the ground, and the horizontal distance between the Hall sensor (2) and the magnetic member (1) is a third preset distance, and is used to detect the vertical distance between the magnetic member (1) and the ground, and sends the detected distance data to the detection component (5);

[0010] The detection component (5) is arranged on the vehicle and is used to determine the total weight of the vehicle bucket and the loaded object based on the received distance data and the preset distance data.

[0011] In some embodiments, the first preset distance is less than or equal to the second preset distance.

[0012] In some embodiments, the first preset distance is the vertical distance between the chassis of the truck box and the ground.

[0013] In some embodiments, the retractable part (3) of the truck bed is arranged vertically to the ground, the movable rocker (4) is arranged horizontally, and one end of the movable rocker (4) is arranged vertically on the retractable part (3) of the truck bed.

[0014] In some embodiments, the detection component (5) is a central control unit of the vehicle, and the central control unit is used to supply power to the Hall sensor (2).

[0015] In some embodiments, the third preset distance is less than or equal to 10 cm.

[0016] In some embodiments, the detection component (5) is also used to determine that the total weight of the truck bucket and the loaded objects exceeds a preset weight when it is determined that the received distance data is less than or equal to a preset distance threshold.

[0017] In some embodiments, the device further comprises a fixing member (6) for fixing the Hall sensor (2) on a side of the front wheel axle of the vehicle close to the cab chassis.

[0018] In some embodiments, the first preset distance and the second preset distance are 80 cm, and the minimum vertical distance between the magnetic member (1) and the ground is 60 cm.

[0019] The present invention has the following beneficial technical effects:

[0020] By setting a movable rocker arm on a retractable part of a vehicle's bucket, setting a non-contact magnetic part on the movable rocker arm, setting a Hall sensor above the axle of the vehicle's front wheel, and setting a detection part electrically connected to the Hall sensor on the vehicle, under the action of a heavy object loaded in the vehicle's bucket, the movable rocker arm can move downward in a direction perpendicular to the ground as the retractable part of the bucket retracts and contracts downward in a direction perpendicular to the ground, thereby causing the non-contact magnetic part to move downward in a direction perpendicular to the ground. At this time, the Hall sensor senses the position change of the non-contact magnetic part (the change in the vertical distance from the ground) in real time, and transmits the real-time detected position data back to the detection part. The detection part determines the total weight of the vehicle's bucket and the loaded object based on the real-time received position data and preset data. In this way, the purpose of non-contact light and heavy load detection of the vehicle is achieved, and the problem that the traditional detection device will be damaged when the vehicle is overloaded and cannot be reused is solved, thereby saving the cost of light and heavy load detection of the vehicle. In addition, the non-contact vehicle light and heavy load detection device proposed by the present invention has a small structure and volume, is easy to carry, has the characteristics of high integration, and occupies a small space, and is easy to promote and apply.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0028] Although the present invention is described herein in conjunction with various embodiments, in the process of implementing the claimed invention, those skilled in the art may understand and implement other variations of the disclosed embodiments by viewing the drawings, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other components or steps, and "one" or "an" does not exclude multiple situations. A single processor or other unit may implement several functions listed in the claims. Certain measures are recorded in different dependent claims, but this does not mean that these measures cannot be combined to produce good results.

[0029] like Figure 1 to Figure 3 As shown, the device comprises: a movable rocker (4) arranged on a retractable part (3) of a vehicle's bucket, a magnetic member (1) arranged at one end of the movable rocker (4) not connected to the retractable part (3) of the bucket, wherein when no object is loaded in the bucket (7), the magnetic member (1) is at a first preset distance from the ground; a Hall sensor (2) arranged on a side of an axle (9) of a front wheel (8) of the vehicle close to a cab chassis (10), and the Hall sensor (2) does not roll with the front wheel (8). The Hall sensor (2) is at a second preset distance from the ground and at a third preset distance from the magnetic member (1), and the Hall sensor (2) is at a first ... Figure 1 , Figure 2 and Figure 3 The magnetic member (1) is electrically connected to the ground surface (not shown) to detect the vertical distance between the magnetic member (1) and the ground, and send the detected distance data to the detection component (5). The detection component (5) is arranged on the vehicle and is used to determine the total weight of the vehicle bucket (7) and the loaded object based on the received distance data and the preset distance data.

[0030] Here, the retractable part (3) of the truck bed can be extended or retracted in a direction perpendicular to the ground as the objects loaded in the truck bed (7) increase or decrease, and when the retractable part (3) of the truck bed is extended or retracted in a direction perpendicular to the ground, the movable rocker (4) can be driven to move up or down in a direction perpendicular to the ground.

[0031] In some embodiments, Figure 1 and Figure 2 As shown, the retractable part (3) of the truck bucket is arranged perpendicular to the ground, the movable rocker (4) is arranged horizontally, and one end of the movable rocker (4) is arranged perpendicularly on the retractable part (3) of the truck bucket; in this way, the movable rocker can always be in a state of being parallel to the vehicle body. For example, the angle between the movable rocker (4) and the chassis of the truck bucket (7) can be 0° (parallel), the angle between the movable rocker (4) and the central axle (9) of the front wheel (8) of the vehicle can be 90°, and the angle between the movable rocker (4) and the ground can be 0°.

[0032] In some embodiments, one end of the movable rocker (4) may be provided with a fixing component, so that the movable rocker (4) can be fixedly set on the retractable component (3) of the truck bed through the fixing component.

[0033] In some embodiments, the magnetic member (1) can be a magnetic block of a fixed shape, for example, a magnetic block of a 10×10 cm cube structure, and can be adsorbed on the end of the movable rocker (4) that is not connected to the retractable part (3) of the truck bed when the movable rocker (4) is a metal rocker.

[0034] In some embodiments, when there is no object loaded in the truck bucket (7), the vertical distance between the magnetic member (1) and the ground is equal to the vertical distance between the Hall sensor (2) and the ground, that is, the first preset distance is equal to the second preset distance. In this way, the vertical distance between the magnetic member (1) and the ground detected by the Hall sensor (2) can be more accurate, thereby making the light and heavy load detection of the vehicle more accurate. Exemplarily, the first preset distance and the second preset distance can be 80 cm.

[0035] In some embodiments, when there is no object loaded in the truck bucket (7), the vertical distance between the magnetic member (1) and the ground may also be smaller than the vertical distance between the Hall sensor (2) and the ground, that is, the first preset distance is smaller than the second preset distance. For example, the first preset distance may be 75 cm, and the second preset distance may be 80 cm.

[0036] In some embodiments, the horizontal distance between the magnetic element (1) and the Hall sensor (2) may be less than or equal to 10 cm, thereby effectively ensuring the detection accuracy of the Hall sensor (2).

[0037] In some embodiments, when there is no object loaded in the truck box (7), the vertical distance between the magnetic member (1) and the ground can be equal to the vertical distance between the chassis of the truck box (7) and the ground, for example, both can be 80 cm.

[0038] In some embodiments, the non-contact vehicle light and heavy load detection device may further include a fixing member (6) for fixing the Hall sensor (2) on a side of the axle (9) of the front wheel (8) close to the cab chassis (10). Figure 2 As shown, the fixing member (6) ( Figure 2 The Hall sensor (2) (not shown) can be arranged perpendicular to the axle (9) and perpendicular to the cab chassis (10), so that the Hall sensor (2) can be fixed just above the axle (9) by the fixing member (6).

[0039] Here, the telescopic part (3) of the truck bed is limited in telescopicity, and thus the distance that the movable rocker (4) moves downward in a direction perpendicular to the ground is also limited, so that there is a minimum vertical distance between the magnetic part (1) and the ground. For example, when there is no object loaded in the truck bed (7), the vertical distance between the magnetic part (1) and the ground is 80 cm, and the minimum vertical distance between the magnetic part (1) and the ground can be 60 cm.

[0040] In some embodiments, the detection component (5) is also used to determine that the total weight of the truck bed and the loaded objects exceeds a preset weight when it is determined that the received distance data is less than or equal to a preset distance threshold.

[0041] Here, the preset weight may be a set overload weight, so that the detection component (5) can detect that the vehicle is overloaded when it is determined that the received distance data is less than or equal to a preset distance threshold.

[0042] In some embodiments, the detection component (5) may be a central control unit of the vehicle, and is used to supply power to the Hall sensor (2).

[0043] In some embodiments, the detection component (5) may also be an electronic device with a power supply and a display screen, and is independently arranged at any position of the vehicle.

[0044] In some embodiments, the Hall sensor (2) can be powered by a USB interface, thus simplifying the electrical connection between the Hall sensor (2) and the detection component (5).

[0045] Here, when a non-contact vehicle light and heavy load detection device is installed on a vehicle and needs to be used, the Hall sensor (2) can be turned on by causing the detection component (5) to start supplying power to the Hall sensor (2), and the initial position of the non-contact magnetic block (1) (the vertical distance between the magnetic block and the ground when there is no object in the bucket) is recorded. When the vehicle is loaded, the movable rocker (4) drives the non-contact magnetic block (1) to move downward. During the process of the non-contact magnetic block (1) moving downward, the Hall sensor (2) records the current position data of the non-contact magnetic block (1) in real time by sensing the position of the non-contact magnetic block (1) in real time, and each position data recorded by the Hall sensor (2) corresponds to the corresponding load weight, thereby achieving the purpose of non-contact light and heavy detection of the vehicle.

[0046] The non-contact vehicle light and heavy load detection device provided by the present invention achieves the purpose of non-contact light and heavy load detection of vehicles, solves the problem that traditional detection devices will be damaged when the vehicle is overloaded and cannot be reused, thereby saving the cost of light and heavy load detection of vehicles. In addition, the non-contact vehicle light and heavy load detection device proposed by the present invention has a small structure and volume, is easy to carry, has a high degree of integration, and occupies a small space, which is easy to promote and apply.

[0047] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
