Description

Technical Field

[0001] The present application relates to the technical field of logistics equipment, and in particular to a wireless collision status monitoring device, a cargo fork and a stacker. Background Art

[0002] In a pallet-level storage solution, goods are placed on a pallet. During the process of outbound or inbound storage, the pallet is picked up by the stacker's fork and taken away from the shelf. When the pallet is damaged, collapsed, or offset, or the shelf sinks or is misaligned, if the fork continues to pick up the pallet, the pallet may fall off the shelf, and the goods may fall off the pallet. Similarly, even when the fork has finished picking up the pallet and takes it away from the shelf, the shaking of the goods may interfere with the shelf, or there may be strips on the pallet that become entangled with the shelf or forks, or there may be relative movement between the pallet and the fork due to inertia, which may cause the pallet and the fork to move relative to each other when the pallet is taken away from the shelf, and the pallet may fall off the shelf, and the goods may fall off the pallet.

[0003] In the related art, in similar scenarios, there is a technical solution of setting a detection device on the fork to achieve timely shutdown when colliding with the goods.

[0004] However, most of the current detection devices are wired devices. In this telescopic fork scenario, wired devices are not only easy to be damaged, but also prone to certain risks due to the wires. Utility Model Content

[0005] The embodiments of the present application provide a wireless impact status monitoring device, a fork and a stacker, which are used to solve the problem in the prior art that the wired detection equipment on the fork is easily damaged and easily brings certain risks due to the wires.

[0006] The embodiment of the present application provides a wireless impact state monitoring device, comprising:

[0007] A collision detection component, used to obtain a trigger signal for determining an abnormal state of the pallet;

[0012] The control module sends the trigger signal to the signal receiving module through the signal sending module.

[0013] In a feasible implementation, the power supply module is configured as a self-generating module;

[0014] Alternatively, the power supply module is configured as a battery.

[0015] In a feasible implementation, the signal sending module and the signal receiving module are connected via an antenna.

[0016] In one possible implementation, the collision detection component includes:

[0021] In a feasible implementation, the collision portion includes a first collision portion and / or a second collision portion. When the collision portion includes the first collision portion and the second collision portion, the first collision portion and the second collision portion are a split structure or an integrated structure.

[0022] The first collision part is used to detect the state of the pallet before forking the pallet;

[0026] In a feasible implementation, the trigger part includes a first state part and a second state part located on both sides of the first state part, and the first state part protrudes from or is recessed from the second state part. In the process of following the forward / backward movement of the collision part, the second state part directly or indirectly triggers the detection sensor.

[0027] In a feasible implementation, the detection end of the detection sensor is facing the trigger part. In the initial state, the detection end of the detection sensor is facing the first state part of the trigger part. When the trigger part moves forward / backward following the collision part, the first state part switches to the second state part to correspond to the detection sensor, and squeezes the detection end of the detection sensor to trigger the detection sensor.

[0028] In a feasible implementation, the integrated front and rear detection mechanism also includes a second transmission mechanism, which is slidably disposed in the shell, and the moving direction of the second transmission mechanism has an angle with the moving direction of the first transmission mechanism, and the trigger part triggers the detection sensor through the second transmission mechanism.

[0052] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0053] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0054] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0056] In the pallet-level storage solution, the goods are placed on the pallet. During the process of outbound or inbound storage, the pallet is picked up by the fork of the stacker and taken away from the shelf. When the pallet is damaged, collapsed, or offset, or the shelf sinks or is misaligned, if the fork continues to pick up the pallet, the pallet will fall off the shelf and the goods will fall off the pallet.

[0057] Similarly, even when the forks have completed picking up and taken the pallet away from the shelf, if the goods shake and interfere with the shelf, or if there are strips on the pallet that get entangled with the shelf or the forks, or if there is relative movement between the pallet and the forks due to inertia, the pallet and the forks may move relative to each other when being taken away from the shelf, which may cause the pallet to fall off the shelf and the goods to fall off the pallet.

[0058] In the related art, in similar scenarios, there is a technical solution of setting a detection device on the fork to achieve timely shutdown when colliding with the cargo. However, most of the current detection devices are wired devices. In such telescopic fork scenarios, wired devices are not only easy to be damaged, but also prone to certain risks due to the wires.

[0059] In order to solve the above problems, the embodiments of the present application provide a wireless collision status monitoring device, a fork and a stacker. The solutions provided by the embodiments of the present application will be described in detail below in conjunction with the drawings in the specification.

[0060] Figure 1 It is a connection block diagram of a wireless impact status monitoring device provided in one embodiment of the present application.

[0061] Reference Figure 1 As shown, an embodiment of the present application provides a wireless collision status monitoring device, including a collision detection component 100 , a control module 200 , a signal sending module 300 , a power supply module 400 and a signal receiving module 500 .

[0062] The collision detection component 100 is used to obtain a trigger signal for determining an abnormal state of the tray.

[0063] The control module 200 is electrically connected to the collision detection assembly 100. For example, the control module 200 may be a single chip microcomputer.

[0064] The power supply module 400 is electrically connected to the collision detection component 100, the control module 200, and the signal transmission module 300, respectively. The power supply module 400 can be configured as a battery or as a self-generating module. It should be noted that the self-generating module is a prior art that works based on the principle of electromagnetic induction, such as a wireless self-generating switch or doorbell. When the collision detection component 100 is collided, electrical energy is generated inside it, which can make the circuit work briefly.

[0065] The signal sending module 300 is electrically connected to the control module 200; the signal receiving module 500 is wirelessly connected to the signal sending module 300; the control module 200 sends the trigger signal to the signal receiving module 500 through the signal sending module 300. It can be understood that the wireless impact state monitoring device transmits signals wirelessly, thereby solving the problem in the prior art that the wired detection equipment on the fork is easily damaged and easily brings certain risks due to the wires.

[0066] Exemplarily, the signal sending module 300 and the signal receiving module 500 are connected via an antenna.

[0067] Figure 2 is a first structural schematic diagram of a collision detection assembly 100 provided in the first embodiment of the present application; Figure 3 yes Figure 2 A schematic structural diagram of the collision detection assembly 100 without the housing 110; Figure 4 is a side view of the collision detection assembly 100 provided in the first embodiment of the present application; Figure 5 is a side view of a collision detection assembly 100 provided in a second embodiment of the present application; Figure 6 is a schematic structural diagram of a collision detection assembly 100 provided in the third embodiment of the present application; Figure 7 is a schematic structural diagram of a collision detection assembly 100 provided in a fourth embodiment of the present application; Figure 8 It is a structural diagram of the collision detection component provided in the fifth embodiment of the present application.

[0068] Reference Figures 2 to 8 The collision detection component includes: a shell 110, a first transmission mechanism 120 and a detection sensor 130.

[0069] The detection sensor 130 is disposed in the housing 110, and is electrically connected to the control module 200. Exemplarily, the detection sensor 130 may be a pressure sensor or a detection switch, and the detection switch may be a wired switch or a wireless autonomous switch.

[0070] In addition, the first transmission mechanism 120 is movably disposed on the housing 110. For example, the first transmission mechanism 120 can be horizontally disposed on the housing 110, and can move in a horizontal direction under the action of an external force.

[0071] The first transmission mechanism 120 is provided with a collision portion 121 , and the collision portion 121 may be located at an end of the first transmission mechanism 120 to facilitate contact and collision with the tray.

[0072] When the first transmission mechanism 120 moves forward / backward along the collision direction after the collision of the collision part 121 , the first transmission mechanism 120 may directly or indirectly trigger the detection sensor 130 .

[0073] Exemplarily, the first transmission mechanism 120 also includes a transmission rod 123 and a first return spring 124. The transmission rod 123 is movably connected to the shell 110. The transmission rod 123 is connected to the collision part 121, and the movement generated by the collision part 121 colliding with the tray is directly or indirectly transmitted to the detection sensor 130. The first return spring 124 is used to reset the transmission rod 123 after it moves.

[0074] like Figure 6 As shown, in one example, the transmission rod 123 is passed through the housing 110, and one end thereof extending out of the housing 110 is connected to the collision portion 121, and the first return spring 124 is sleeved on the transmission rod 123 and is located between the housing 110 and the collision portion 121. The detector 130 is horizontally arranged inside the housing 110, and the detection end of the detection sensor 130 faces the collision portion 121 and contacts with one end of the transmission rod 123 away from the collision portion 121. When the transmission rod 123 moves in a direction toward the detection sensor 130, the transmission rod 123 will trigger the detection sensor 130. Specifically, when forking a pallet, if the pallet is in an abnormal state, the collision portion 121 at the end of the transmission rod 123 will collide with the pallet, and drive the transmission rod 123 to move in a direction toward the detection sensor 130, thereby triggering the detection sensor 130.

[0075] like Figure 7As shown, in another example, the transmission rod 123 is provided on the housing 110, and one end thereof extending out of the housing 110 is hinged with the collision part 121, the middle position of the collision part 121 is hinged with the housing 110, and one end of the collision part 121 away from the transmission rod 123 protrudes from the surface of the housing 110. The detector 130 is horizontally arranged inside the housing 110, and the detection end of the detection sensor 130 faces the collision part 121 and contacts with one end of the transmission rod 123 away from the collision part 121. When the transmission rod 123 moves in the direction toward the detection sensor 130, the transmission rod 123 will trigger the detection sensor 130. Specifically, after forking a pallet, if the pallet is in an abnormal state, the collision part 121 will collide with the pallet on the side facing the housing 110, and the collision part 121 drives the transmission rod 123 to move in the direction toward the detection sensor 130, thereby triggering the detection sensor 130.

[0076] like Figure 8 As shown, in another example, the transmission rod 123 is provided on the housing 110, and one end thereof extending out of the housing 110 is fixedly connected to the collision part 121, and one end of the collision part 121 away from the transmission rod 123 protrudes from the surface of the housing 110. The detector 130 is horizontally arranged inside the housing 110, and the detection end of the detection sensor 130 faces away from the collision part 121 and contacts with one end of the transmission rod 123 away from the collision part 121. After forking the pallet, if the pallet is in an abnormal state, the collision part 121 will collide with the pallet on the side facing the housing 110, and the collision part 121 drives the transmission rod 123 to move in a direction away from the detection end of the detection sensor 130, thereby causing the end of the transmission rod 123 to trigger the detection sensor 130.

[0077] like Figure 6 The detection embodiment before forking shown is the same as Figure 7 or Figure 8 The post-fork detection embodiment shown can be installed on the forks at the same time to take into account the entire process of pre-fork detection and post-fork detection.

[0078] Reference Figures 2 to 5 As shown, the first transmission mechanism 120 also includes a triggering part 122, which can change the direction of force transmission to trigger the detection sensor 130. The triggering part 122 can be set in the middle position of the first transmission mechanism 120 and is located inside the housing 110. When the first transmission mechanism 120 moves horizontally along the axial direction, the triggering part 122 moves horizontally driven by the first transmission mechanism 120. It can be understood that since the first transmission mechanism 120 can trigger the detection sensor 130 when it moves forward or backward along its axis, it can detect the state of the pallet in two directions before and after the pallet is forked, compared with the prior art, it not only saves the number of detection sensors 130 used, but also reduces the installation space of the pallet abnormal state monitoring device.

[0079] Reference Figure 4 As shown, in some examples, the tray abnormal state monitoring device also includes a second transmission mechanism 140, and the moving direction of the second transmission mechanism 140 has an angle with the moving direction of the first transmission mechanism 120. During the movement of the first transmission mechanism 120, the trigger part 122 drives the second transmission mechanism 140 to move, thereby triggering the detection sensor 130.

[0080] Specifically, one end of the second transmission mechanism 140 contacts the triggering portion 122, and the detection end of the detection sensor 130 abuts against the second transmission mechanism 140. During the operation of the first transmission mechanism 120, the second transmission mechanism 140 is driven to operate, thereby triggering the detection sensor 130. It can be understood that by providing the second transmission mechanism 140 in the housing 110, the force direction of the detection sensor 130 can be changed, thereby facilitating the spatial layout of the entire device and the installation of different detection sensors 130.

[0081] Exemplarily, the second transmission mechanism 140 is disposed inside the housing 110 and vertically disposed on the housing 110 , with one end connected to the inner wall of the housing 110 and the other end abutting against the triggering portion 122 of the first transmission mechanism 120 .

[0082] The detection sensor 130 is fixedly arranged on the housing 110, and the detection end of the detection sensor 130 faces the second transmission mechanism 140. Specifically, the detection sensor 130 can be arranged between the second transmission mechanism 140 and the housing 110. For example, in some examples, there is a certain space between the bottom of the second transmission mechanism 140 (the end where the second transmission mechanism 140 is connected to the housing 110) and the housing 110, and the detection sensor 130 can be arranged in the space, and when the second transmission mechanism 140 moves downward in the vertical direction, a certain pressure is applied to the detection end of the detection sensor 130. Alternatively, the detection sensor 130 can be arranged on the side of the second transmission mechanism 140, and when the second transmission mechanism 140 moves downward in the vertical direction, a certain pressure can be applied to the detection end of the detection sensor 130 through other components connected thereto. It should be noted that the detection end of the detection sensor 130 refers to the end of the detection sensor 130 used to detect pressure.

[0083] In the pallet abnormal state monitoring device, when the first transmission mechanism 120 moves axially due to the action of external force, the first transmission mechanism 120 will drive the second transmission mechanism 140 to move through the trigger part 122, so that the second transmission mechanism 140 applies pressure to the detection sensor 130, so that the abnormal state of the goods can be detected in time according to the pressure change detected by the detection sensor 130, thereby avoiding accidents of goods falling.

[0084] It should be noted that the first transmission mechanism 120 moves axially due to the external force, which means that the first transmission mechanism 120 moves in any direction of the axial direction due to the external force. For example, when the first transmission mechanism 120 is subjected to a thrust, the first transmission mechanism 120 moves to the right, and when the first transmission mechanism 120 is subjected to a pulling force, the first transmission mechanism 120 moves to the left. In other words, due to the presence of the triggering part 122, no matter whether the first transmission mechanism 120 moves to the left or to the right along the axial direction, the first transmission mechanism 120 can cause the second transmission mechanism 140 to move and apply pressure to the detection sensor 130.

[0085] That is to say, the device for monitoring the abnormal state of the tray can detect the forces in two directions by only providing one detection sensor 130, thereby reducing the number of sensors used and lowering the manufacturing cost.

[0086] Reference Figure 5 As shown, in some other examples, the detection end of the detection sensor 130 may also be directly connected to the trigger portion 122 , and the trigger portion 122 can trigger the detection sensor 130 during the movement of the first transmission mechanism 120 .

[0087] Reference Figures 2 to 5 As shown, the first return spring 124 is used to return the transmission rod 123 to an initial position after following the forward / backward movement of the collision portion 121 . When the transmission rod 123 is at the initial position, the detection sensor 130 corresponds to the first state portion 1221 .

[0088] Exemplarily, the first return spring 124 includes a first spring 1241 and a second spring 1242, and the transmission rod 123 is a rod-shaped member having a first end and a second end opposite to each other. The transmission rod 123 is arranged on the housing 110, and the first end and the second end of the transmission rod 123 both extend out of the housing 110. The triggering portion 122 is arranged between the first end and the second end and is located in the housing 110. The collision portion 121 is fixedly arranged at the first end, and the collision portion 121 protrudes from or is recessed from the surface of the housing 110 so as to be able to accept both thrust and tension. Exemplarily, the collision portion 121 can be a plate-shaped member.

[0089] For example, after the abnormal state monitoring device of the pallet is fixedly installed on the fork, if the pallet is damaged, collapsed, offset, or the shelf sinks or is installed misaligned, the fork will not be able to accurately extend into the pallet. When the fork is extended to pick up the goods, the collision part 121 will contact the goods or the pallet and push the transmission rod 123 to move. During the movement of the transmission rod 123, the second transmission mechanism 140 can be driven to move and squeeze the detection sensor 130, and finally the detection sensor 130 detects the pressure.

[0090] When the fork picks up the goods and takes them away from the shelf, if the goods interfere with the shelf due to shaking, if there are strip-shaped items on the pallet and they are entangled with the shelf or the fork, or if there is relative movement between the pallet and the fork due to inertia, the goods will first contact the collision portion 121 protruding or recessed from the surface of the shell 110, and then pull the transmission rod 123 to move. During the movement of the transmission rod 123, the second transmission mechanism 140 can be driven to move and squeeze the detection sensor 130, so that the detection sensor 130 finally detects pressure.

[0091] In addition, the first spring 1241 is sleeved on the transmission rod 123, and the first spring 1241 is located between the collision portion 121 and the housing 110; the second spring 1242 is sleeved on the transmission rod 123, and the second spring 1242 is located between the second end and the housing 110. After the external force is removed, the transmission rod 123 can return to its original position under the action of the first spring 1241 or the second spring 1242. In addition, a pin 150 is provided at the second end of the transmission rod 123 to block the second spring 1242 and prevent it from falling off from the transmission rod 123.

[0092] Reference Figure 4 and Figure 5 As shown, the trigger portion 122 includes a first state portion 1221 and a second state portion 1222 located on both sides of the first state portion 1221, and the first state portion 1221 is protruding from or recessed from the second state portion 1222. In the process of following the forward / backward movement of the collision portion 121, the second state portion 1222 directly or indirectly triggers the detection sensor 130.

[0093] Specifically, when the first state portion 1221 is a convex portion, the second state portion 1222 is a concave portion, and when the first state portion 1221 is a concave portion, the second state portion 1222 is a convex portion.

[0094] When the first state portion 1221 is recessed in the second state portion 1222 , the first state portion 1221 and the second state portion 1222 enclose a force application space 1223 , and an end of the second transmission mechanism 140 or a detection end of the detection sensor 130 is disposed in the force application space 1223 .

[0095] In some examples, when the first transmission mechanism 120 drives the triggering portion 122 to move, the second state portion 1222 will squeeze the second transmission mechanism 140, forcing it to move downward and exert pressure on the detection sensor 130, causing it to generate a trigger signal. That is, in the process of following the forward / backward movement of the collision portion 121, the second state portion 1222 indirectly triggers the detection sensor 130.

[0096] In some other examples, the detection end of the detection sensor 130 faces the trigger portion 122. In the initial state, the detection end of the detection sensor 130 faces the first state portion 1221 of the trigger portion 122. When the trigger portion 122 moves forward / backward following the contact portion, the first state portion 1221 switches to the second state portion 1222 to correspond to the detection sensor 130, and squeezes the detection end of the detection sensor 130 to trigger the detection sensor 130. That is, in the process of following the forward / backward movement of the collision portion 121, the second state portion 1222 directly triggers the detection sensor 130.

[0097] On the contrary, in some examples, the first state portion 1221 protrudes from the second state portion 1222. In the initial state, one end of the second transmission structure abuts against the first state portion 1221, and at this time, the other end of the second transmission structure applies a large force to the detection sensor 130. After the first transmission structure moves horizontally under the action of an external force, one end of the second transmission structure is transformed to abut against the first state portion 1221, and at this time, the force applied by the other end of the second transmission structure to the detection sensor 130 changes, thereby triggering the detection sensor 130.

[0098] In addition, the triggering part 122 and the transmission rod 123 are of a separate structure or an integrated structure. For example, the first state part 1221 and the second state part 1222 can be processed on the transmission rod 123. Alternatively, a force transmission plate is fixedly arranged on the transmission rod 123, and the force transmission plate is configured as the triggering part 122. For example, the force transmission plate is configured as a peak structure with wings on both sides or a valley structure with wings on both sides.

[0099] The force transmission plate is fixed to the side of the transmission rod 123, and a bending area is provided on the force transmission plate, and the bending area is configured as a force application space 1223. The second transmission mechanism 140 abuts against the force application space 1223, and the transmission rod 123 drives the second transmission mechanism 140 to move through the force transmission plate, thereby applying pressure to the detection sensor 130. Exemplarily, the bending area is surrounded by two inclined side walls and a bottom wall. It can be understood that the two inclined side walls facilitate the application of force to the second transmission mechanism 140, which can force it to move, thereby applying pressure to the detection sensor 130 at the other end.

[0100] In some other examples, a first protrusion and a second protrusion are spaced apart on the portion of the transmission rod 123 located inside the shell 110, the first protrusion and the second protrusion are configured as a second state portion 1222, the portion of the transmission rod 123 between the first protrusion and the second protrusion is configured as a first state portion 1221, the space between the first protrusion and the second protrusion is configured as a force application space 1223, the second transmission mechanism 140 abuts against the force application space 1223, and the transmission rod 123 drives the second transmission mechanism 140 to move via the first protrusion and the second protrusion, thereby applying pressure to the detection sensor 130.

[0101] For example, when the fork picks up the goods, if the fork cannot accurately pick up the hole of the pallet, the transmission rod 123 will be pushed by the goods and move away from the shelf. At this time, the first protrusion will squeeze the second transmission mechanism 140, forcing it to move downward and apply pressure to the detection sensor 130. Conversely, when the fork picks up the pallet and is about to take it away from the shelf, if the goods move due to pulling or other reasons and push the transmission rod 123 to move towards the shelf, the second protrusion on the transmission rod 123 will squeeze the second transmission mechanism 140, forcing it to move downward and apply pressure to the detection sensor 130.

[0102] In addition, in order to facilitate the first protrusion and the second protrusion to apply force to the second transmission mechanism 140, the first protrusion and the second protrusion both have inclined side walls.

[0103] Continue to refer to Figures 2 to 4 As shown, the second transmission mechanism 140 includes an abutment block 141 and a limiting column 142. The abutment block 141 is slidably arranged in the shell 110. A second return spring 143 is arranged between the abutment block 141 and the shell 110. The sliding direction of the abutment block 141 is perpendicular to the moving direction of the trigger part 122. One end of the abutment block 141 acts on the trigger part 122, and the side end of the abutment block 141 abuts against the detection sensor 130 through an inclined surface.

[0104] Exemplarily, one end of the abutment block 141 abuts in the force application space 1223 of the first transmission mechanism 120, the limiting column 142 is fixedly arranged at the other end of the abutment block 141, the limiting column 142 is slidably arranged on the housing 110, the second return spring 143 is sleeved on the limiting column 142, one end of the second return spring 143 abuts on the abutment block 141, the other end of the second return spring 143 abuts on the housing 110, and the detection end of the detection sensor 130 faces the abutment block 141. It can be understood that under the action of the second return spring 143, the abutment block 141 can abut in the force application space 1223. When the abutment block 141 is subjected to the force applied by the first transmission mechanism 120, it will overcome the elastic force of the second return spring 143 and move, and apply a force to the detection sensor 130 toward the abutment block 141. After the force applied by the first transmission mechanism 120 to the abutment block 141 is removed, the abutment block 141 will move up and return to its original position under the elastic force of the second return spring 143. At this time, the force between the abutment block 141 and the detection sensor 130 also returns to its initial size (0 or a fixed value).

[0105] In addition, in some examples, the corresponding ends of the abutment block 141 and the trigger portion 122 and the detection end of the detection sensor 130 are all provided with a rolling member 144. Exemplarily, the rolling member 144 is rotatably arranged at the end of the abutment block 141 facing away from the limiting column 142 through the installation shaft, and the outer edge of the rolling member 144 contacts the first transmission mechanism 120. Specifically, the rolling member 144 is located in the force application space 1223, and its outer edge abuts against the trigger portion 122. It can be understood that since the rolling member 144 can rotate around the installation shaft, when the first transmission mechanism 120 moves along its axial direction, there is a smaller friction between the first transmission mechanism 120 and the rolling member 144, which is beneficial to the horizontal movement of the first transmission mechanism 120 and to the vertical movement of the abutment block 141.

[0106] Continue to refer to Figure 3 As shown, in some examples, the second transmission mechanism 140 further includes a guide rail 146 and a slider 145, one end of the guide rail 146 is fixedly disposed on the housing 110, and the guide rail 146 is parallel to the limiting column 142, the slider 145 is fixedly disposed on the abutment block 141, and the slider 145 is cooperatively connected with the guide rail 146 to enable the abutment block 141 to move along the guide rail 146. Exemplarily, the limiting column 142 is vertically disposed on the housing 110, and the abutment block 141 moves in the vertical direction under the action of the limiting column 142, and correspondingly, the guide rail 146 is vertically disposed on the housing 110, and under the cooperative action of the slider 145 and the guide rail 146, the abutment block 141 moves stably in the vertical direction.

[0107] Continue to refer to Figures 2 to 4 As shown, in some examples, the detection sensor 130 is horizontally arranged in the housing 110, and an abutment groove is arranged on the side of the abutment block 141, the abutment groove has a side wall with an inclined angle, the detection end of the detection sensor 130 is located in the abutment groove, and the side wall selectively applies pressure to the detection sensor 130. Specifically, when the abutment block 141 is moved downward by the force of the trigger part 122, the side wall of the abutment groove will apply pressure to the detection end of the detection sensor 130, and vice versa, the side wall of the abutment groove will not apply pressure to the detection end of the detection sensor 130.

[0108] Continue to refer to Figure 2 and Figure 3 As shown, the collision part 121 includes a first collision part 1211 and a second collision part 1212. The first collision part 1211 is used to detect the state of the pallet before forking the pallet; the second collision part 1212 is used to detect the state of the pallet after forking the pallet; the first collision part 1211 and the second collision part 1212 are separate structures or integrated structures.

[0109] In some examples, the first collision portion 1211 and the second collision portion 1212 are separate structures, and the first collision portion 1211 and the second collision portion 1212 are respectively disposed at the same side end of the transmission rod 123. In addition, the upper surface of the second collision portion 1212 protrudes from the upper surface of the housing 110.

[0110] Reference Figure 2 and Figure 3 As shown, in some other examples, the first collision portion 1211 and the second collision portion 1212 are an integrated structure, the second collision portion 1212 is located on the first collision portion 1211, the first collision portion 1211 is fixed to the end of the transmission rod 123, and the second collision portion 1212 protrudes from the upper surface of the shell 110.
