[0040] See also Figure 1 , Figure 1This is a schematic diagram of the use of a clamping vehicle in an embodiment of the present application. An embodiment of the present invention provides a clamping vehicle 100, which is used to carry cylindrical cargo. The clamping vehicle 100 includes a vehicle body 10, a clamping arm assembly 20, a turntable 140, and a first driving member 30. The clamping arm assembly 20 is used to clamp cylindrical cargo. The turntable 140 is rotatably connected to the vehicle body 10, and the clamping arm assembly 20 is disposed on the turntable 140. The clamping arm assembly 20 can rotate around the first axis b relative to the vehicle body 10 through the turntable 140 to adjust the placement posture of the cylindrical cargo. The first driving member 30 is connected to the turntable 140 to drive the turntable 140 to rotate around the first axis b relative to the vehicle body 10.

[0041] The clamping vehicle can clamp cylindrical goods by providing a clamping arm assembly 20. By providing a turntable 140 rotatably connected to the vehicle body 10, and arranging the clamping arm assembly 20 on the turntable 140, and the clamping arm assembly 20 can rotate around the first axis b relative to the vehicle body 10 through the turntable 140, the placement posture of the cylindrical goods can be adjusted. By providing a first driving member 30 connected to the turntable 140, the turntable 140 can be driven to rotate around the first axis b relative to the vehicle body 10, thereby driving the clamping arm assembly 20 to rotate around the first axis b relative to the vehicle body 10, thereby adjusting the placement posture of the cylindrical goods.

[0042] In some embodiments, the turntable 140 can drive the clamp arm assembly 20 to rotate relative to the vehicle body 10 around the second axis b, so that the clamp arm assembly 20 switches between the first state and the second state. When the clamp arm assembly 20 is in the first state, the cylindrical cargo 1 is placed horizontally, and when the clamp arm assembly 20 is in the second state, the cylindrical cargo 1 is placed vertically. In this way, by setting the clamp arm assembly 20 to have the first state and the second state, the cylindrical cargo 1 is placed horizontally or vertically, so that the placement posture of the cylindrical cargo 1 corresponds to different usage needs.

[0043] Specifically, the turntable 140 drives the clamp arm assembly 20 to rotate 90 degrees around the second axis b relative to the vehicle body 10, so that the clamp arm assembly 20 switches between the first state and the second state.

[0044] In some embodiments, the clamping vehicle includes a first driving member 30 connected to the turntable 140 , and the first driving member 30 is used to drive the turntable 140 to rotate around the first axis b relative to the vehicle body 10 .

[0045] In some embodiments, the clamp arm assembly 20 can move in a vertical direction relative to the vehicle body 10 to clamp the cylindrical cargo 1 at different heights, and the clamp arm assembly 20 can place the clamped cylindrical cargo 1 at different heights.

[0046] In some embodiments, Figure 2-4As shown, the clamping vehicle further includes a mounting frame 50 connected to the vehicle body 10, and a turntable 140 is connected to the vehicle body 10 by means of the mounting frame 50, and the turntable 140 can rotate relative to the mounting frame 50 about the first axis b. The mounting frame 50 is configured to be able to move in a vertical direction relative to the vehicle body 10, so as to drive the clamping arm assembly 20 to rise and fall relative to the vehicle body 10 by means of the turntable 140.

[0047] Specifically, Figure 3 As shown, the first driving member 30 is disposed on one side where the turntable 140 is connected to the mounting bracket 50 .

[0048] In some embodiments, the clamping vehicle includes a second driving member (not shown) connected to the first clamping arm 21, and the second driving member is used to drive the first clamping arm 21 to rotate relative to the vehicle body 10 around the second axis a, so that the first clamping arm 21 is close to or away from the second clamping arm 22, so that the size of the clamping space is changed, thereby clamping cylindrical goods 1 of different diameters, and making the clamping vehicle have a small number of parts and a simple structure.

[0049] In some embodiments, the clamping vehicle further includes a third driving member (not shown) connected to the second clamping arm 22, and the third driving member is used to drive the second clamping arm 22 to rotate relative to the vehicle body 10 around the second axis a. In this way, the first clamping arm 21 and the second clamping arm 22 are driven by the second driving member and the third driving member respectively to clamp cylindrical goods 1 of different diameters, and the first clamping arm 21 and the second clamping arm 22 can move simultaneously to approach or move away from each other, so that the clamping arm assembly 20 is more flexible when clamping the cylindrical goods 1.

[0050] Figure 5 for Figure 1 A schematic diagram of the structure of the clamping vehicle in the illustrated embodiment from another perspective.

[0051] In some embodiments, Figure 5 As shown, the clamping vehicle further includes a controller 80 electrically connected to the second driving member, and the controller 80 is used to control the second driving member to drive at least one of the first clamping arm 21 and the second clamping arm 22 connected to the second driving member to rotate relative to the vehicle body 10 around the second axis a, so as to be able to clamp cylindrical goods 1 of different diameters. Therefore, by setting the controller 80, the cylindrical goods 1 can be automatically clamped.

[0052] In one embodiment, the controller 80 is electrically connected to the second driving member and the third driving member respectively. The controller 80 is used to control the second driving member to drive the first clamping arm 21 to rotate around the second axis a relative to the vehicle body 10, and is used to control the third driving member to drive the second clamping arm 22 to rotate around the second axis a relative to the vehicle body 10.

[0053] In some embodiments, the controller 80 is also electrically connected to the first driving member, and the controller 80 is used to control the first driving member to drive the turntable 140 to rotate.

[0054] In some embodiments, Figure 4 As shown, the clamping vehicle further includes two in-place detection switches 170 respectively arranged on the turntable 140, and the two in-place detection switches 170 are respectively used to detect whether the clamping arm assembly 20 is in the first state or the second state. The controller 80 is electrically connected to the two in-place detection switches 170 respectively, so that when one of the in-place detection switches 170 detects that the clamping arm assembly 20 is in the first state, or when the other in-place detection switch 170 detects that the clamping arm assembly 20 is in the second state, the controller 80 can control the first driving member to stop driving. In this way, by setting two in-place detection switches 170 to detect whether the clamping arm assembly 20 has rotated to the first state or the second state, when the clamping arm assembly 20 is in the first state or the second state, the controller 80 can control the third driving member to stop driving, thereby realizing the automatic switching of the clamping arm assembly 20 between the first state and the second state.

[0055] In some embodiments, Figure 2 and Figure 4-5 As shown, the clamping vehicle further includes a first reflector 90, a second reflector 100, and a first laser sensor 40 electrically connected to the controller 80. The first reflector 90 is disposed on the first clamping arm 21, the second reflector 100 is disposed on the second clamping arm 22, and the first laser sensor 40 is disposed on the vehicle body. The first laser sensor 40 can detect the distance between the first laser sensor 40 and the first reflector 90, and the distance between the first laser sensor 40 and the second reflector 100. The controller 80 can determine the distance between the first reflector 90 and the second reflector 100 based on the distance between the first laser sensor 40 and the first reflector 90, and the distance between the first laser sensor 40 and the second reflector 100 fed back by the first laser sensor 40, and in combination with a preset algorithm. The controller 80 can also determine the size of the clamping space according to the distance between the first reflector 90 and the second reflector 100 and in combination with another preset algorithm, and can also control the second driving member to drive the first clamping arm 21 and the second clamping arm 22 to rotate around the second axis a relative to the vehicle body 10 according to the size of the clamping space. In this way, the clamping arm assembly 20 can automatically clamp the cylindrical cargo 1, and avoid the cylindrical cargo 1 being damaged due to excessive clamping force or being unable to clamp the cylindrical cargo 1 due to insufficient clamping force.

[0056] It is understandable that if Figure 4As shown, the first laser reflector 40 is not coaxially arranged with the second axis a, so that when at least one of the first clamp arm 21 and the second clamp arm 22 rotates relative to the vehicle body 10, the distance between the first laser reflector 40 changes, so that the distance between the first laser sensor 40 and the first clamp arm 21 or the second clamp arm 22 obtained by the first laser sensor 40 corresponds to the different positions of the first clamp arm 21 or the second clamp arm 22 relative to the vehicle body 10.

[0057] Specifically, the first reflective member 90 is disposed on a side of the first clamping arm 21 away from the vehicle body 10, the second reflective member 100 is disposed on a side of the second clamping arm 22 away from the vehicle body 10, and the first laser sensor 40 is disposed on a side where the vehicle body and the clamping arm assembly 20 are connected, so that the first laser sensor 40 can emit laser to the first reflective member 90 and the second reflective member 100 or receive reflected laser.

[0058] Alternatively, if Figure 2 and Figure 4 As shown, the first reflective member 90 is disposed on a side of the first clamping arm 21 close to the first laser sensor 40, and the first reflective member 90 extends in a direction parallel to the second axis a, and the second reflective member 100 is disposed on a side of the second clamping arm 22 close to the first laser sensor 40, and the second reflective member 100 extends in a direction parallel to the second axis a, so that the first laser sensor 40 is respectively arranged opposite to the first reflective member 90 and the second reflective member 100, so as to avoid interference from other parts during the process of the first laser sensor 40 emitting laser or receiving reflected laser.

[0059] In one embodiment, Figure 2 and Figure 4 As shown, the first reflector 90 and the second reflector 100 are respectively configured to be cylindrical. In other embodiments, the first reflector 90 and the second reflector 100 may also be configured to be other shapes, such as a cuboid, a flat plate, etc., which are not limited here.

[0060] Figure 6 for Figure 1 A schematic diagram of the structure of the clamping vehicle in the illustrated embodiment from another perspective.

[0061] In order to obtain the size of the cylindrical cargo 1, in some embodiments, as Figure 6As shown, the clamping vehicle further includes a second laser sensor 110 disposed on the vehicle body 10, the second laser sensor 110 is electrically connected to the controller 80, and the second laser sensor 110 is used to detect the size of the cylindrical cargo 1. The controller 80 can control the second driving member to drive at least one of the first clamping arm 21 and the second clamping arm 22 connected to the second driving member to rotate relative to the vehicle body 10 around the second axis a according to the size of the cylindrical cargo 1 fed back by the second laser sensor 110, so that the size of the clamping space is adapted to the size of the cylindrical cargo 1. In this way, by setting the second laser sensor 110 to obtain the size of the cylindrical cargo 1, there is no need to use manual measurement and other methods, thereby improving the efficiency of clamping the cylindrical cargo 1 and the degree of automation of the clamping vehicle.

[0062] Specifically, the second laser sensor 110 is disposed on a side where the vehicle body 10 is connected to the clamp arm assembly 20 .

[0063] In some embodiments, Figure 6 As shown, the second laser sensor 110 is also used to detect the position of the cylindrical cargo 1. The clamping vehicle also includes a traveling mechanism 150 connected to the vehicle body 10, and the controller 80 is electrically connected to the traveling mechanism 150. The controller 80 can control the traveling mechanism 150 to drive the clamping vehicle to move to the position of the cylindrical cargo 1 according to the position of the cylindrical cargo 1 fed back by the second laser sensor 110, and the controller 80 can also control the traveling mechanism 150 to drive the clamping vehicle to move to the cargo release position according to the preset trajectory stored in itself. In this way, the clamping vehicle can automatically move to the position of the cylindrical cargo 1 to pick up the cargo, and can automatically transport the cylindrical cargo 1 to the cargo release position after picking up the cargo.

[0064] In actual use, the controller 80 controls the traveling mechanism 150 to drive the clamping vehicle to move to the position of the cylindrical cargo 1 according to the position of the cylindrical cargo 1 fed back by the second laser sensor 110, and controls the second driving member to drive at least one of the first clamping arm 21 and the second clamping arm 22 to rotate relative to the vehicle body 10 to clamp the cylindrical cargo 1. After clamping the cylindrical cargo 1, the controller 80 controls the traveling mechanism 150 to drive the clamping vehicle to move to the cargo release position according to the preset trajectory stored in the controller 80, and controls the second driving member to drive at least one of the first clamping arm 21 and the second clamping arm 22 to rotate relative to the vehicle body 10 to release the cylindrical cargo 1 and place the cylindrical cargo 1 at the cargo release position.

[0065] In some embodiments, Figure 6 As shown, the traveling mechanism 150 includes a driving wheel 151 rotatably disposed on the vehicle body 10 , and the controller 80 is electrically connected to the driving wheel 151 . The controller 80 can control the driving wheel 151 to rotate relative to the vehicle body 10 to drive the clamping vehicle to move.

[0066] Furthermore, if Figure 6As shown, the traveling mechanism 150 further includes a plurality of sets of load-bearing wheels 152 rotatably disposed on the vehicle body 10 .

[0067] In one embodiment, Figure 6 As shown, there are three groups of load-bearing wheels 152 , and the three groups of load-bearing wheels 152 and the driving wheels 151 are respectively disposed at the four corners of the vehicle body 10 .

[0068] In some embodiments, Figure 2 As shown, the clamping vehicle also includes a camera 120 disposed on the vehicle body 10, and the camera 120 is electrically connected to the controller 80. The camera 120 is used to collect image information of the object corresponding to the position of the clamping vehicle, and the controller 80 is used to position the clamping vehicle according to the image information of the object collected by the camera 120. In this way, by setting the camera 120 to obtain image information in the environment where the clamping vehicle is located, the controller 80 can position the clamping vehicle, so that the clamping vehicle can move to the position of the cylindrical cargo 1 to clamp the cylindrical cargo 1, and after clamping the cylindrical cargo 1, the clamped cylindrical cargo 1 can be transported to the cargo release position. Compared with the traditional laser positioning method, the camera 120 has a strong anti-interference ability to interference factors such as light, and the positioning error is small, thereby improving the positioning accuracy of the clamping vehicle.

[0069] It should be noted that, in actual use, the object may be a QR code located in the cargo hold, the QR code recording position information corresponding to the posture of the clamping vehicle, and the camera 120 determines the posture of the clamping vehicle by photographing the QR code.

[0070] Figure 7 for Figure 1 A partial top view of the gripper vehicle in the illustrated embodiment.

[0071] Furthermore, if Figure 2 and Figure 7 As shown, the clamping vehicle further includes a fill light assembly 130, which is disposed around the camera 120 to provide fill light for the camera 120, thereby facilitating the camera 120 to obtain image information of the object.

[0072] In one embodiment, Figure 7 As shown, the fill light assembly 130 includes two fill light pieces 131, which are respectively connected to the vehicle body 10 and respectively located on both sides of the camera 120 to provide relatively uniform illumination to different sides of the camera 120. In other embodiments, the number and arrangement of the fill light pieces 131 may also be configured in other ways according to usage requirements, as long as they can effectively fill light for the camera 120 so that the camera 120 can accurately obtain image information of the object being photographed, and this is not limited here.

[0073] Figure 8 for Figure 1A schematic diagram of the structure of the camera and obstacle avoidance module in the illustrated embodiment.

[0074] In some embodiments, Figure 8 As shown, the clamping vehicle further includes an obstacle avoidance module 160 disposed on the vehicle body 10, the obstacle avoidance module 160 is electrically connected to the controller 80, and the obstacle avoidance module 160 is used to transmit a signal to sense an obstacle. In this way, the controller 80 can control the walking mechanism 150 to drive the clamping vehicle to avoid the obstacle according to the obstacle information fed back by the obstacle avoidance module 160.

[0075] Optionally, the obstacle avoidance module 160 may adopt an ultrasonic obstacle avoidance module to send ultrasonic signals and feed back the collected signals reflected by the obstacle to the controller 80 so that the controller 80 can obtain the distance between the obstacle and the clamping vehicle.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
