[0039] In the related art, there is a technical problem of low limiting efficiency when limiting the position of goods. The embodiment of the present application provides a limiting device, which can at least solve the technical problem of low limiting efficiency when transporting goods to a certain extent.

[0040] The present application is described below with reference to the accompanying drawings and specific embodiments: like Figure 1 and Figure 2 As shown, the limiting device 100 is installed on the cargo box 200 and is used to limit the cargo 300 in the cargo box 200.

[0041] like Figure 3 and Figure 4 As shown, the limiting device 100 includes a support unit 110 , a limiting unit 120 and a driving unit 130 .

[0042] The support unit 110 is used to be fixedly connected to the cargo box 200 .

[0043] The support unit 110 is an installation base for the limiting unit 120 and the driving unit 130, and is used to support the limiting unit 120 and the driving unit 130. The support unit 110 can be fixedly connected to the cargo box 200 by welding, bolt connection, clamping, etc.

[0044] The limiting unit 120 is slidably connected to the supporting unit 110 , and can slide in a direction toward the cargo 300 to come into contact with the cargo 300 .

[0045] The limiting unit 120 is used to interfere with the goods 300 in the cargo box 200, thereby limiting the position of the goods 300, reducing the shaking of the goods 300 during transportation, and ensuring the stability of the goods 300 during transportation.

[0046] The driving unit 130 is installed on the supporting unit 110 and connected to the limiting unit 120 to drive the limiting unit 120 to slide.

[0047] The driving unit 130 is fixedly mounted on the support unit 110 and connected to the limiting unit 120 to drive the limiting unit 120 to slide back and forth. Figure 6 and Figure 7 As shown, when the driving unit 130 drives the limiting unit 120 to slide toward the side close to the cargo 300 (that is, when the limiting unit 120 is driven to extend), the limiting unit 120 can contact the cargo 300, thereby limiting the cargo 300. Figure 5 As shown, when the driving unit 130 drives the limiting unit 120 to slide toward the side away from the cargo 300 (that is, when the limiting unit 120 is driven to retract), the limiting unit 120 gradually moves away from the cargo 300 and no longer limits the cargo 300, so that the cargo 300 can be taken out of the cargo box 200.

[0048] Before the cargo 300 is loaded into the cargo box 200 , the driving unit 130 can drive the limiting unit 120 to retract to a position that does not affect the loading of the cargo 300 . After the cargo 300 is loaded, the driving unit 130 drives the limiting unit 120 to extend until the limiting unit 120 conflicts with the cargo 300 .

[0049] Driven by the driving unit 130, the limiting unit 120 has a plurality of different position states, that is, the limiting unit 120 can extend to different lengths, so that the limiting unit 120 can limit goods 300 of different sizes and adapt to goods 300 of different specifications, which is convenient for users to use, helps to reduce the workload of users, and improves the limiting efficiency. There is no need to configure each size of goods 300 separately like a wooden wedge.

[0050] Driven by the driving unit 130, the limiting unit 120 automatically moves toward the side close to the cargo 300 or toward the side far away from the cargo 300, eliminating the manual operation of limiting with wooden wedges in a narrow and dangerous space, and alleviating the problems of heavy workload and low work efficiency in the transportation, installation and disassembly of large items.

[0051] The application scenarios of the limit device 100 are diverse and are not limited in this application. In some embodiments, the limit device 100 is installed on a special transport vehicle to limit the position of an aircraft on the special transport vehicle. In some embodiments, the limit device 100 is installed on an ordinary freight vehicle to limit the position of, for example, household appliances, industrial appliances, building materials, etc.

[0052] like Figure 8 and Fig. 9 As shown, in some embodiments, the limiting unit 120 includes a stop assembly 121 and a transmission assembly 126, the stop assembly 121 is used to contact the cargo 300 and is movably connected to the transmission assembly 126, and the transmission assembly 126 is slidably connected to the support unit 110 and connected to the driving unit 130.

[0053] The transmission assembly 126 is slidably connected to the support unit 110 and connected to the driving unit 130, and the stop assembly 121 is connected to the transmission assembly 126. Therefore, under the action of the driving unit 130, the transmission assembly 126 can slide and drive the stop assembly 121 to slide, so that the stop assembly 121 can contact the cargo 300.

[0054] The stop assembly 121 is movably connected to the transmission assembly 126, so that when the end surfaces of the cargo 300 contacting the stop assembly 121 are not flush, or when the end surfaces of the cargo 300 contacting the stop assembly 121 are deflected due to road bumps during transportation, the stop assembly 121 can be movable to adapt to changes in the state of the cargo 300 before or during transportation, which helps to ensure the contact area between the stop assembly 121 and the cargo 300, so that the stop assembly 121 and the cargo 300 can fit better, ensure the limiting performance of the limiting device 100, thereby ensuring the stability of the cargo 300 during transportation and reducing the shaking of the cargo 300.

[0055] like Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, in some embodiments, the stopper assembly 121 includes a stopper ball 122, a stopper 123 for contacting the cargo 300, and a connection seat 124 fixedly connected to the stopper 123, and the connection seat 124 is provided with a spherical groove 124a and a cylindrical hole 124b connected to the spherical groove 124a; the transmission assembly 126 includes a first transmission member 127 and a ball head member 128, the first transmission member 127 is slidably connected to the support unit 110 and connected to the driving unit 130, and the ball head member 128 includes a ball head rod 1282 and a fixed arrangement A ball head portion 1281 is provided at one end of the ball head rod portion 1282, and the other end of the ball head rod portion 1282 is fixedly connected to the first transmission member 127. The ball head portion 1281 is arranged in the spherical groove 124a, and part of the ball head rod portion 1282 is located in the cylindrical hole 124b; the inner wall of the spherical groove 124a is also provided with a limiting groove 124c extending along the sliding direction of the limiting unit 120, the limiting ball 122 is arranged in the limiting groove 124c, and at least part of the limiting ball 122 is located in the ball head portion 1281 and fixedly connected to the ball head portion 1281.

[0056] The size of the ball head 1281 is adapted to the size of the spherical groove 124a, so that the ball head 1281 can be located in the spherical groove 124a to form a ball joint with the connecting seat 124, so that the connecting seat 124 can rotate around the ball head member 128.

[0057] The limiting groove 124c, the cylindrical hole 124b, the limiting ball 122, and the ball head rod 1282 are provided to limit the rotation direction and the rotation range of the connecting seat 124, so that the connecting seat 124 can only rotate in a specified direction, that is, only along the Fig.13 After such design, the stopper 123 cannot rotate around the axis of the ball head rod 1282, preventing the stopper 123 from damaging the goods 300.

[0058] Specifically, a limiting groove 124c extending along the sliding direction of the limiting unit 120 is opened on the inner wall of the spherical groove 124a, the length dimension of the limiting groove 124c is greater than the diameter of the limiting ball 122, the width dimension of the limiting groove 124c is equal to the diameter of the limiting ball 122, the limiting ball 122 is located in the limiting groove 124c, and at least a part of the limiting ball 122 is located in the ball head 1281 and fixedly connected to the ball head 1281, so that the connecting seat 124 can only rotate around the first rotation direction or along the second rotation direction.

[0059] Specifically, when the connecting seat 124 rotates around the ball head 128, the limiting groove 124c will be driven to rotate together. Since the limiting ball 122 is located in the limiting groove 124c, when the limiting groove 124c rotates until the inner wall conflicts with the limiting ball 122, the connecting seat 124 will not be able to continue to move, thereby limiting the rotation range of the connecting seat 124; or after the ball head rod 1282 rotates to conflict with the inner wall of the cylindrical hole 124b, the connecting seat 124 will not be able to continue to rotate, thereby limiting the rotation range of the connecting seat 124.

[0060] It should be noted that the size of the ball head 1281 is larger than the size of the cylindrical hole 124b to prevent the ball head 1281 from passing through the cylindrical hole 124b and escaping from the spherical groove 124a.

[0061] The maximum rotation range of the connecting seat 124 can be controlled by controlling the length of the limiting groove 124c, controlling the gap value between the ball head rod 1282 and the cylindrical hole 124b, or controlling the length of the cylindrical hole 124b, which is not limited in the present application.

[0062] In some embodiments, the axis of the ball head rod 1282 is parallel to the sliding direction of the limiting unit 120, the cross section of the ball head rod 1282 is circular, and the cross section of the cylindrical hole 124b is also circular. The diameter of the ball head 1281 is larger than the diameter of the cylindrical hole 124b to prevent the ball head 1281 from falling out of the spherical groove 124a.

[0063] In some embodiments, the rotation range of the connecting seat 124 is limited by the contact between the ball head rod portion 1282 and the inner wall of the cylindrical hole 124b.

[0064] like Fig.10 and Fig.13 As shown, in some embodiments, the connecting seat 124 includes a ball head seat 1241 and a first half ring 1242 and a second half ring 1243 fixedly connected to the ball head seat 1241, the first half ring 1242 and the second half ring 1243 are arranged opposite to each other, the first half ring 1242 and the second half ring 1243 are together formed into a cylindrical hole 124b, the first half ring 1242, the second half ring 1243 and the ball head seat 1241 are together formed into a spherical groove 124a, and the second half ring 1243 and the ball head seat 1241 are together formed into a limiting groove 124c.

[0065] The first half ring 1242 and the second half ring 1243 are both semicircular. After the first half ring 1242 and the second half ring 1243 are fixedly connected to the ball head seat 1241, they form a circular ring. The hole in the middle of the circular ring is the cylindrical hole 124b. The circular ring formed by the first half ring 1242 and the second half ring 1243 is set outside the ball head rod to limit the ball head 1281. Such a design can facilitate the connection between the connecting seat 124 and the ball head component 128. After such a design, the ball head component 128 with the fixed limiting ball 122 can be placed in the ball head seat 1241 first, and then the first half ring 1242 and the second half ring 1243 can be connected to the ball head seat 1241. After the first half ring 1242 and the second half ring 1243 are installed, the ball head 1281 is located in the spherical groove 124a, the ball head rod 1282 is located in the cylindrical hole 124b, and the limiting ball 122 is located in the limiting groove 124c.

[0066] In some embodiments, the stopper 123 is arc-shaped, the ball head seat 1241 is arranged in the middle of the stopper 123, and the axis of the stopper 123 is parallel to the sliding direction of the limiting unit 120. This design makes the stopper 123 suitable for resisting the goods 300 with a cylindrical or cylindrical cross section, and facilitates the limiting of the cylindrical or cylindrical goods 300.

[0067] In some embodiments, the first half ring 1242 and the second half ring 1243 have the same structure, and the first half ring 1242 and the second half ring 1243 are fixedly connected to the ball head seat 1241 by bolts.

[0068] In some embodiments, the limiting device 100 also includes a controller (not shown in the figure) and a first sensor 140 arranged on the limiting unit 120. The controller is electrically connected to the first sensor 140 and the driving unit 130. The first sensor 140 is used to detect whether the limiting unit 120 is in contact with the cargo 300. The controller is used to control the driving unit 130 to stop moving when the limiting unit 120 is in contact with the cargo 300.

[0069] These embodiments detect whether the limit unit 120 is extended to contact the goods 300 through the first sensor 140. Before the limit unit 120 contacts the goods 300, the controller automatically controls the driving unit 130 to continue to move, so that the limit unit 120 continues to extend. After the limit unit 120 contacts the goods 300, the controller automatically controls the driving unit 130 to stop, so that the limit unit 120 stops moving and no longer extends. The function of the limit unit 120 automatically extending until it contacts the goods 300 is realized, making the limit device 100 more automated and reducing the labor intensity of users.

[0070] The type of the first sensor 140 is various and is not limited in the present application.

[0071] The first sensor 140 may be a distance sensor. The first sensor 140 detects a first distance between the limiting unit 120 and the goods 300, specifically, the distance between the surface of the stopper 123 used to contact the goods 300 and the surface of the goods 300 used to contact the stopper 123 in the sliding direction of the limiting unit 120. When the detected first distance is 0, it means that the stopper 123 is in contact with and in contact with the goods 300. At this time, the driving unit 130 can be controlled by the controller to stop, so that the limiting unit 120 is maintained at the extended length when stopped, so that the limiting unit 120 always contacts the goods 300. When the detected distance is greater than 0, it means that the stopper 123 has not yet contacted the goods 300, and the stopper 123 needs to continue to extend.

[0072] The first sensor 140 may also be a pressure sensor, which may be installed on the end surface of the position limiting unit 120 for contacting with the goods 300. When the pressure sensor detects pressure, it means that the position limiting unit 120 contacts and contacts with the goods 300. At this time, the driving unit 130 may be controlled to stop by the controller, so that the position limiting unit 120 remains in the stopped state, so that the position limiting unit 120 always contacts with the goods 300. When the pressure sensor does not detect pressure, it means that the stopper 123 has not yet contacted with the goods 300, and the stopper 123 needs to extend toward the goods 300.

[0073] In some embodiments, the first sensor 140 is a distance sensor, which is installed on the end surface of the stopper 123 that is used to contact the cargo 300. The stopper assembly 121 also includes a gasket 125 fixedly arranged on the stopper 123. Specifically, the gasket 125 is arranged on the end surface of the stopper 123 that is used to contact the cargo 300. The gasket 125 is made of flexible materials such as rubber and nylon, and has a certain buffering capacity when subjected to force. An avoidance opening for avoiding the first sensor 140 is opened on the gasket 125. The gasket 125 can prevent the stopper 123 from scratching the surface of the cargo 300, and can also protect the first sensor 140 to a certain extent to prevent the first sensor 140 from being squeezed and deformed.

[0074] When the cargo box 200 has not yet been filled with cargo 300, Figure 5 As shown, the limiting unit 130 can be controlled to be in a fully retracted state to prevent the limiting unit 130 from interfering with the loading of the goods 300. In order to ensure that the limiting unit 130 can be automatically retracted to the fully retracted state, as shown in FIG. Figure 3As shown, in some embodiments, the limit device 100 also includes a controller and a second sensor 150 arranged on the support unit 110, the controller is electrically connected to the second sensor 150 and the driving unit 130, the second sensor 150 is used to detect whether the limit unit 120 is in a retracted state, and the controller is used to control the driving unit 130 to stop when the limit unit 120 is in the retracted state.

[0075] These embodiments determine whether the limit unit 120 is in a fully retracted state through the second sensor 150. When the limit unit 120 is not fully retracted, the controller automatically controls the drive unit 130 to continue to move, so that the limit unit 120 continues to retract. When the limit unit 120 is fully retracted, the controller automatically controls the drive unit 130 to stop, so that the limit unit 120 stops moving, and the limit unit 120 remains in a fully retracted state, thereby realizing the function of the limit unit 120 automatically retracting to a fully retracted state, making the limit device 100 more automated and reducing the labor intensity of users.

[0076] The types of the second sensor 150 are various and are not limited in the present application. The second sensor 150 can be a position sensor, specifically, a proximity sensor or a contact sensor. When the limit assembly 120 retracts to the specified position, the position sensor sends an electrical signal to the controller, and the controller controls the drive unit 130 to stop. The second sensor 150 can be a distance sensor, and the distance sensor is used to detect the distance between the second sensor 150 and the distance sensor in the sliding direction of the limit unit 120. The controller is used to control the drive unit to stop when the distance meets the set requirements. Specifically, when the drive unit drives the limit unit to move toward the side away from the goods, the distance between the limit unit and the second sensor gradually decreases. When the distance is less than the set value, it means that the limit unit is retracted into place, and the drive unit 130 can be controlled to stop.

[0077] In some embodiments, the position limiting unit 120 has a sliding portion 1261, the support unit 110 is provided with a guide groove 110a extending along the sliding direction of the position limiting unit 120, and the sliding portion 1261 is located in the guide groove 110a to achieve a sliding connection between the support unit 110 and the position limiting unit 120. In these embodiments, the second sensor 150 is a proximity position sensor, and when the sliding portion 1261 retracts into the detection range of the second sensor 150, the second sensor 150 sends an electrical signal to the controller, and the controller controls the driving unit 130 to stop.

[0078] Please combine Figure 3 , Fig.14 and Fig.15As shown, in some embodiments, the driving unit 130 includes a mounting seat 131, a second transmission member 132 and a driving member 133. The mounting seat 131 is fixedly connected to the support unit 110; the second transmission member 132 is rotatably connected to the mounting seat 131 and is threadedly matched with the limiting unit 120; the driving member 133 is transmission-connected to the second transmission member 132 for driving the second transmission member 132 to rotate.

[0079] The mounting seat 131 is a mounting base for the second transmission member 132 and the driving member 133, and supports the second transmission member 132 and the driving member 133. The mounting seat 131 is fixedly connected to the support unit 110, and the second transmission member 132 is rotatably connected to the mounting seat 131. Specifically, the axis of the second transmission member 132 is parallel to the sliding direction of the limiting unit 120, and the second transmission member 132 is rotatably connected to the mounting seat 131 around its own axis. The second transmission member 132 is threadedly matched with the limiting unit 120, and the driving member 133 is transmission-connected to the second transmission member 132 for driving the second transmission member 132 to rotate. The rotation of the driving member 133 can drive the second transmission member 132 to rotate. Due to the threaded matching, the rotation of the second transmission member 132 can drive the limiting unit 120 to slide along the sliding direction of the limiting unit 120. Since the limiting unit 120 is slidably connected to the support unit 110, the limiting unit 120 does not rotate, but only slides along the sliding direction of the limiting unit 120.

[0080] It should be noted that the driving member 133 can drive the second transmission member 132 to rotate clockwise or counterclockwise, so that the limiting unit 120 moves toward the side close to the cargo 300, that is, extends, or moves toward the side away from the cargo 300, that is, retracts.

[0081] The second transmission member 132 and the limiting unit 120 are threadedly matched, so that the limiting unit 120 can slide steplessly, that is, slide continuously, so that the position of the limiting unit 120 is more flexible and easier to use the limiting device 100. The second transmission member 132 and the limiting unit 120 are threadedly matched, and the thread tooth shape can be set to form a self-locking between the limiting unit 120 and the second transmission member 132, thereby ensuring the stability of the limiting unit 120.

[0082] In some embodiments, the outer circumference of the second transmission member 132 is provided with an external thread, the inner wall of the first transmission member 127 of the limiting unit 120 is provided with an internal thread, and the second transmission member 132 is threadedly connected in the limiting unit 120 .

[0083] In some embodiments, the tooth profiles of the internal thread and the external thread are both trapezoidal.

[0084] In some embodiments, the second transmission member 132 is a lead screw.

[0085] like Fig.15 As shown, in some embodiments, the driving unit further includes a clutch 134, which is connected to the output end of the second transmission member 132 and the driving member 133, and the clutch 134 is detachably connected to the output end, and a screwing portion connected to a screwing tool is provided on the clutch 134. The mounting seat 131 is sleeved outside the second transmission member 132 and the clutch 134, and an avoidance hole (not shown in the figure) is provided in the area of ​​the mounting seat 131 opposite to the screwing portion 1341, and the screwing portion 1341 is exposed to the outside through the avoidance hole.

[0086] The structure of the clutch 134 is diverse and is not limited in the present application. The clutch 134 is arranged between the second transmission member 132 and the driving member 133. One end of the clutch 134 is fixedly connected to the second transmission member 132, and the other end is detachably connected to the output end of the driving member 133. The driving member 133 can drive the clutch 134 to rotate, thereby driving the second transmission member 132 to rotate. The clutch 134 and the driving member 133 are detachably connected, and a screwing portion 1341 is arranged on the clutch 134, so that when the driving member 133 is damaged and the extension or retraction of the limit unit 120 needs to be manually adjusted, the clutch 134 can be screwed by a tool such as a wrench, so that the clutch 134 drives the second transmission member 132 to rotate. An avoidance hole is provided on the mounting seat 131 for avoiding the screwing tool, so that the screwing tool can be inserted into the second mounting sleeve through the avoidance hole, and then the clutch 134 is screwed.

[0087] In some embodiments, the screwing portion is hexagonal.

[0088] In some embodiments, the driving member 133 includes a motor and a reducer. The reducer reduces the speed of the high-speed motor to achieve the output required for predetermined use. In these embodiments, the clutch 134 and the output end of the reducer are connected by a key, and the clutch 134 and the second transmission member 132 are connected by a pin.

[0089] In some embodiments, the mounting seat 131 includes a first mounting sleeve 1311 and a second mounting sleeve 1312, the first mounting sleeve 1311 is sleeved outside the second transmission member 132 and fixedly connected to the support unit 110, and the second transmission member 132 is rotatably connected to the first mounting sleeve 1311; the second mounting sleeve 1312 is sleeved outside the clutch 134, and the second mounting sleeve 1312 is fixedly connected to the first mounting sleeve 1311, and an avoidance hole is opened in the area of ​​the second mounting sleeve 1312 opposite to the position of the screwing part 1341.

[0090] In some embodiments, the mounting base 131 further includes a shielding cover 1313, which is detachably connected to the second mounting sleeve 1312. When the shielding cover 1313 is connected to the second mounting sleeve 1312, the shielding cover 1313 shields the avoidance hole. With this design, when the clutch 134 is not rotated by a screwing tool, the shielding cover 1313 can shield the avoidance hole to prevent external impurities such as rainwater and dust from entering the second mounting sleeve 1312, thereby protecting the clutch 134 in the second mounting sleeve 1312.

[0091] In some embodiments, the support unit 110 includes a support 111, a support column 112, a guide slide seat 113 and a fixed seat 114; the support 111 is fixedly connected to the cargo box 200; the support 111 is fixedly connected to one side of the support column 112, and the other side of the support column 112 is fixedly connected to the cargo box 200; the guide slide seat 113 is fixedly connected to the support 111, and the limiting unit 120 is slidably connected to the guide slide seat 113; the fixed seat 114 is fixedly connected to the support 111, and the driving unit 130 is fixedly connected to the fixed seat 114.

[0092] The support column 112 is used to support the support 111, one side of the support column 112 is fixedly connected to the support 111, and the other side of the support column 112 is fixedly connected to the cargo box 200. The support 111 is fixedly connected to the cargo box 200, and the support column 112 is also fixedly connected to the cargo box 200, which ensures the overall stability of the limiting device 100. A guide slide seat 113 and a guide slide limiting unit 120 are arranged on the support 111, and a fixed seat 114 is arranged on the support 111 to fix the driving unit 130, which can facilitate the processing of the limiting device 100. After the support 111, the support column 112, the guide slide seat 113 and the fixed seat 114 are processed separately, the support 111, the support column 112, the guide slide seat 113 and the fixed seat 114 are connected to form the limiting device 100.

[0093] like Figure 1 and Figure 2 As shown, based on the same inventive concept, an embodiment of the present application further provides a cargo storage device 1000 , which includes a cargo box 200 and a limiting device 100 , wherein a support unit 110 of the limiting device 100 is connected to the cargo box 200 .

[0094] The cargo box 200 of the cargo storage device 1000 may be provided with one limiting device 100, and of course, it may also be provided with multiple limiting devices, which is not limited in this application. Since the cargo storage device 1000 includes the limiting device 100, it naturally has all the beneficial effects of the limiting device 100, which will not be described in detail here.

[0095] In some embodiments, the cargo storage device 1000 includes a cargo box 200 and two of the above-mentioned limiting devices 100. The cargo box 200 has two vertical plates 210 arranged opposite to each other and a bottom plate 220 arranged between the two vertical plates and connected to the two vertical plates 210, and the two vertical plates 210 and the bottom plate 220 together form a receiving groove 200a for receiving the cargo 300; the two limiting devices 100 are respectively installed on the two vertical plates 210, and the sliding direction of the limiting unit 120 is parallel to the length direction of the cargo box 200, and the limiting unit 120 is located in the receiving groove 200a.

[0096] The receiving groove 200a is used to receive the goods 300, and the goods 300 are placed in the receiving groove 200a. The opening of the receiving groove 200a faces upward, and the goods 300 can be placed in the receiving groove 200a by hoisting or other means. The vertical plate 210 and the bottom plate 220 are fixedly connected, and the bottom plate 220 is fixedly connected to the lower end of the vertical plate 210. One of the limiting devices 100 is installed on one of the vertical plates 210, and the other limiting device 100 is installed on the other vertical plate 210. The two limiting devices 100 limit the two sides of the goods 300 respectively, which can improve the stability of the goods 300. The sliding direction of the limiting unit 120 is parallel to the length direction of the cargo box 200, so that the limiting unit 120 extends or retracts in the length direction of the cargo box 200, so that the limiting unit 120 can provide support for the goods 200 in the length direction of the cargo box 200, which can reduce the shaking amount of the goods 200 in the length direction of the cargo box 200.

[0097] like Figure 1 and Figure 3 As shown, in some embodiments, a mounting groove 210a is provided on the vertical plate 210, and the support unit 110 includes a support 111, a support column 112, a guide slide seat 113 and a fixed seat 114. The support 111 is located in the mounting groove 210a and is fixedly connected to the inner wall of the mounting groove 210a; the support column 112 is located in the mounting groove 210a, the support 111 is fixedly connected to one side of the support column 112, and the other side of the support column 112 is fixedly connected to the inner wall of the mounting groove 210a; the guide slide seat 113 is fixedly connected to the support 111, and the limit unit 120 is slidably connected to the guide slide seat 113 along the sliding direction of the limit unit 120; the fixed seat 114 is fixedly connected to the support 111, and the driving unit 130 is fixedly connected to the fixed seat 114.

[0098] The support column 112 is arranged along the height direction of the cargo box 200. The support column 112 is used to support the support 111. The upper end of the support column 112 is fixedly connected to the support 111, and the lower end of the support column 112 is fixedly connected to the bottom wall of the installation groove 210a. The support 111 is fixedly connected to the side wall of the installation groove 210a, and the lower end of the support column 112 is fixedly connected to the bottom wall of the installation groove 210a, which ensures the overall stability of the limiting device 100. The support 111 and the support column 112 are located in the installation groove 210a, which means that at least part of the support 111 and the support column 112 are located in the installation groove 210a. The installation groove 210a is opened on the vertical plate 210 to install the support 111 and the support column 112, which can reduce the space occupied by the support 111 and the support column 112 in the width direction of the receiving groove 200a, so that the receiving groove 200a can store goods 300 with a larger width. A guide sliding seat 113 and a guide sliding limiting unit 120 are arranged on the support 111, and a fixed seat 114 and a fixed driving unit 130 are arranged on the support 111, so as to facilitate the processing of the limiting device 100. The support 111, the support column 112, the guide sliding seat 113 and the fixed seat 114 can be processed separately, and then the support 111, the support column 112, the guide sliding seat 113 and the fixed seat 114 are connected to form the limiting device 100.

[0099] In these embodiments, the guide slide groove 110 a extending along the sliding direction of the limiting unit 120 is provided on the guide slide seat 113 .

[0100] like Figure 4As shown, in some embodiments, the support 111 includes a mounting plate 1111, a first vertical plate 1112, a second vertical plate 1113, a connecting plate 1114, and a plurality of reinforcing plates 1115; the first vertical plate 1112 and the second vertical plate 1113 are arranged opposite to each other, and the mounting plate 1111 is arranged between the first vertical plate 1112 and the second vertical plate 1113 and is fixedly connected to the first vertical plate 1112 and the second vertical plate 1113. The supporting column 112 is arranged on a side of the first vertical plate 1112 away from the mounting plate 1111 and is fixedly connected to the first vertical plate 1112, and the first vertical plate 1112 and the supporting column 112 enclose a reinforcing cavity with a rectangular cross section. The connecting plate 1114 is arranged on a side of the second vertical plate 1113 away from the mounting plate 1111, and the connecting plate 1114 includes a first plate segment 11141 and a second plate segment 11142 which are arranged vertically and fixedly connected, the first plate segment 11141 and the second plate segment 11142 are fixedly connected, and a plurality of reinforcing plates 1115 are arranged at intervals along the length direction of the support column 112, the reinforcing plates 1115 are located between the first vertical plate 1112 and the second vertical plate 1113, and are fixedly connected to the first vertical plate 1112, the second vertical plate 1113, the mounting plate 1111 and the connecting plate 1114. In these embodiments, the first plate segment 11141 is fixedly connected to the inner wall of the receiving groove 200a by bolts, the second plate segment 11142 is fixedly connected to the inner wall of the mounting groove 210a by bolts, and the guide slide seat 113 and the fixing seat 114 are fixedly connected to the mounting plate 1111 by bolts.

[0101] In some embodiments, the mounting plate 1111 includes a mounting plate body 11111 and a stop 11112 fixedly connected to the mounting plate body 11111, the stop 11112 protrudes from the mounting plate body 11111, the guide sliding seat 113 and the fixed seat 114 are fixedly connected to the mounting plate body 11111 by bolts, and along the retraction direction of the limiting unit 120, the stop 11112 is located on the front side of the fixed seat 114, and the fixed seat 114 is in contact with the stop 11112. With this design, when the limiting unit 120 contacts the cargo 300, the cargo 300 will exert force on the limiting unit 120 along the retraction direction of the limiting unit 120, and the driving unit 130 is installed on the fixed seat 114, so that the fixed seat 114 will be subjected to a force along the retraction direction of the limiting unit 120. At this time, the stop 11112 can support the fixed seat 114 and provide the fixed seat 114 with a force in the direction of the guide sliding seat 113, thereby improving the load-bearing performance of the fixed seat 114.

[0102] The working principle of the limiting device 100 is introduced as follows: When there is no cargo 300 placed in the cargo box 200, the driving unit 130 is activated, driving the clutch 134 to rotate, thereby driving the second transmission member 132 to rotate clockwise, and the second transmission member 132 is threadedly matched with the first transmission member 127, driving the first transmission member 127 to retract into the first mounting sleeve 1311. When the sliding portion 1261 on the first transmission member 127 moves to be sensed by the second sensor 150, it means that the first transmission member 127 is retracted into place, and the second sensor 150 will send an electrical signal to the controller, and the controller will control the driving unit 130 to stop moving. At this point, the limit unit 120 is in a fully retracted state. Figure 5 shown.

[0103] After the cargo 300 is placed in the cargo box 200, the driving unit 130 is activated to drive the clutch 134 to rotate in the opposite direction, thereby driving the second transmission member 132 to rotate counterclockwise. The second transmission member 132 is threadedly engaged with the first transmission member 127, driving the first transmission member 127 to gradually extend out of the first installation sleeve 1311. Figure 7 As shown, when the first sensor 140 detects that the limiting unit 120 is in contact with the goods 300, the first sensor 140 will send an electrical signal to the controller, and the controller will control the driving unit 130 to stop moving. At this point, the limiting unit 120 will be in contact with the goods 300, and the goods 300 will be limited. Figure 1 shown.

[0104] If the extended length of the limit unit 120 is manually adjusted, the shielding cover 1313 can be removed, and the clutch 134 can be separated from the output end of the driving member 133, and then the clutch 134 can be screwed clockwise or counterclockwise using a screwing tool such as a wrench.
