Description

Technical Field

[0001] The present invention relates to the field of express delivery technology, and in particular to a lever barrel, a collision protection device and an express delivery sorting system. Background Art

[0002] The express delivery sorting system includes a transport line, sorting vehicles that run along the transport line, and sorting units located on one or both sides of the transport line. The sorting vehicles are used to sort express deliveries of different routes and classify them into sorting units.

[0003] The sorting vehicle consists of a roller assembly and a movement. Parcels are placed on a platform formed by the roller assembly. The roller assembly's power input is connected to the movement's power output. As the movement moves along the conveyor line, the movement, in conjunction with the track, drives the roller assembly platform to rotate horizontally, transporting the parcels to the sorting area.

[0004] However, the movement of sorting vehicles along the conveyor line causes vibrations, which can cause bolts and other debris to fall off and enter the track. If the movement strikes these debris during operation, it can overload the movement or transmit excessive torque to the track, causing damage to the movement or rollers, increasing maintenance costs for the express sorting system. Summary of the Invention

[0005] (1) Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an insurance mechanism for an express sorting system and an express sorting system, which solves the technical problem that when the movement collides with bolts and other debris during the operation of the sorting vehicle, it is easy to cause damage to the movement or roller, resulting in high maintenance costs for the express sorting system.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] In a first aspect, an embodiment of the present invention provides a lever barrel, comprising:

[0010] Cylinder;

[0011] A rod body, the rod body being inserted into the cylinder body and being rotatable relative to the cylinder body around the axis of the rod body, the rod body inserted into the cylinder body protruding from the peripheral wall of the cylinder body to provide a stress point capable of breaking;

[0012] The inner wall of the cylinder and the peripheral wall of the rod are provided with a limiting assembly for limiting the upper and lower positions of the rod and enabling the cylinder and the rod to be detachably connected.

[0013] According to the present invention, the stress point is an annular groove provided on the central peripheral wall of the rod body.

[0014] According to the present invention, the upper portion of the rod body can be inserted into the cylinder body, and a bearing is sleeved on the upper portion of the rod body;

[0015] The limiting assembly includes a first limiting groove provided on the inner wall of the lower portion of the cylinder and a second limiting groove provided on the peripheral wall of the upper portion of the rod;

[0016] A first limiting member capable of abutting against the bottom of the bearing is detachably provided in the first limiting groove, and a second limiting member capable of abutting against the top of the bearing is detachably provided in the second limiting groove.

[0017] According to the present invention, the number of the bearings is two, and the upper peripheral wall of the rod body is further provided with a bearing boss located between the second limiting groove and the stress point, and the two bearings are respectively provided on both sides of the bearing boss.

[0018] According to the present invention, both the first limiting member and the second limiting member are clip springs.

[0019] In a second aspect, the present invention further provides a collision protection device, comprising a lever barrel, wherein the collision protection device is capable of moving along a first horizontal direction, and further comprising:

[0020] a housing, wherein the cylinder is connected to the housing so as to rotate about a second horizontal direction perpendicular to the first horizontal direction;

[0021] A triggering member, the triggering member is provided on the housing to carry and transmit the triggering action;

[0022] a third limiting member, the third limiting member being provided on the housing and capable of limiting the lever barrel so as to keep the lever barrel in a working state;

[0024] When the trigger member is triggered, the third limiting member releases the limit on the lever barrel, and the lever barrel can enter the failure state from the working state;

[0025] When the trigger member is triggered and the lever barrel is still in the working state, the lever body can be triggered to break at the stress point of the lever body.

[0026] According to the present invention, the trigger member includes a trigger portion, a hinge portion, and a shift fork connected in sequence, and the hinge portion is connected to the housing in a rotational manner around the second horizontal direction;

[0027] The third limiting member includes a spring, one end of which abuts against the side wall of the housing;

[0029] The upper portion of the rod is inserted into the cylinder, the lower portion of the rod protrudes from the shell, and a limiting hole is provided on the cylinder;

[0030] When the lever barrel is in the working state, the pressure-bearing portion is kept compressed by the spring so that the latch pin keeps fitting with the limiting hole; when the trigger member is triggered, the shift fork shifts the pressure-bearing portion to shorten the spring, thereby causing the latch pin to disengage from the limiting hole, thereby releasing the swing restriction of the lever barrel; when the trigger member is triggered but the latch pin does not disengage from the limiting hole and the lever barrel is still in the working state, the rod body can be triggered to cause the stress point of the rod body to break;

[0031] The working state corresponds to a state in which the latch pin and the limiting hole remain engaged, thereby keeping the lever barrel perpendicular to the lateral extension direction of the shell; the failure state corresponds to a state in which the latch pin and the limiting hole are disengaged, thereby causing the lever barrel to tilt relative to the lateral extension direction of the shell.

[0032] According to the present invention, the collision protection device further comprises a rotating member;

[0033] The rotating member is a tension spring, and both ends of the tension spring are hung on the tension spring connecting holes on the outer shell and the peripheral wall of the cylinder respectively; or,

[0035] The rotating member is used to apply a torque to the cylinder body to cause the lever cylinder to swing between the working state and the failure state.

[0036] According to the present invention, a notch extending from the top of the cylinder to the limiting hole is provided, which is inclined to the axial direction of the cylinder;

[0037] A gasket coaxial with the limiting hole is provided on the peripheral wall of the cylinder;

[0038] The peripheral wall of the cylinder is provided with a pin connecting hole for passing a pin so as to be rotatably connected to the shell;

[0039] The position where the pin shaft connecting hole is provided on the peripheral wall of the cylinder is a plane for fitting with the shell.

[0040] In a third aspect, the present invention further provides an express sorting system, comprising the collision protection device according to any one of claims 1 to 4, further comprising:

[0041] Line body;

[0042] A track, the track being arranged on the linear body;

[0043] A sorting vehicle is operated along the extension direction of the line; the collision protection device is slidably connected to the sorting vehicle along the width direction of the sorting vehicle, and the rod body of the lever cylinder in a working state can contact and cooperate with the track;

[0044] When the triggering member is triggered by debris on the track, the lever barrel swings from the working state to the failure state;

[0045] When the triggering member is triggered by the debris on the track and the lever cylinder is still in the working state, the rod body can be triggered by the debris on the track to cause the stress point of the rod body to break.

[0046] (3) Beneficial effects

[0047] The beneficial effects of the present invention are as follows: the lever cylinder provided by the present invention can rotate around the axis of the lever body relative to the cylinder when the lever body is loaded, thereby avoiding hard contact between the lever body and the load-applying mechanism such as a track, thereby reducing the friction loss of the lever body, extending the service life of the lever body, and reducing the noise during the operation of the lever body.

[0048] Furthermore, when the rod body strikes a bolt or other debris during operation, it breaks at the stress point, preventing the load from being transferred to the mechanism that mates with the lever barrel and causing damage to the mechanism, thereby extending the service life of the mechanism. Furthermore, the detachable connection between the barrel and the rod body allows for easy replacement of the rod body if it breaks, and the rod body is relatively low in cost, thus reducing maintenance costs.

[0049] Therefore, the lever cylinder can be used in conjunction with a mechanism that needs to bear a load and / or has multiple loading directions, and has a wide range of adaptability.

[0050] In the collision protection device and express sorting system of the present invention, the outer shell serves as an assembly base for the lever barrel, the trigger member and the third limit member, wherein the barrel body of the lever barrel is rotatably connected to the outer shell, and the rod body of the lever barrel is used to cooperate with the track and drive the movement to operate, thereby driving the roller assembly to operate. When the trigger member is triggered, the third limit member releases the swing position limit of the lever barrel, causing it to enter a failure state from a working state. The triggering method of the trigger member includes but is not limited to images and mechanical contact actions. Since the use of mechanical contact actions can realize the identification of objects such as bolts intuitively, quickly and at low cost, mechanical contact actions are preferably used as the triggering method of the trigger member in this embodiment. The swing limiting methods of the lever by the third limit member include but are not limited to mechanical limiting and magnetic limiting. The mechanical limiting method is preferably used in this embodiment.

[0051] In the present invention, when a bolt or other debris is present in the track, the trigger member is activated, and the third limiter releases the swing restriction on the lever barrel, causing the lever barrel to enter a disabled state from its active state. This in turn causes the lever barrel's rod to derail, preventing the lever barrel from continuing to move and being damaged and failing due to excessive load. Furthermore, this prevents the lever barrel from transmitting load to the sorting vehicle's movement and track, causing damage and failure. Furthermore, if the trigger member fails to activate, while the lever barrel remains in its active state, the collision protection device continues to operate. If the lever barrel collides with debris, the rod barrel can break at a stress point, causing the rod barrel to derail, preventing the rod barrel from transmitting load from the debris to the sorting vehicle's movement and track, causing damage and failure. Therefore, when a bolt or other debris is present in the track, the collision protection device provides dual protection measures, including "the lever barrel swinging out of the track" and "the lever barrel breaking out of the track." This enhances the collision protection device's effectiveness in protecting the sorting vehicle and track, effectively extending the service life of the sorting vehicle and track. Furthermore, since the rod body and the cylinder body are detachably connected, even if the rod body breaks, it can be easily replaced. Moreover, the rod body is inexpensive, which can greatly improve the convenience of maintenance and reduce maintenance costs compared to sorting vehicles and tracks that are expensive to maintain.

[0075] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0076] Example 1

[0077] See also Figure 1-11 , an embodiment of the present invention provides a lever barrel.

[0078] The lever barrel 2 includes a barrel 21 and a rod 22. The rod 22 is inserted into the barrel 21 and can rotate relative to the barrel 21 about its axis. The rod 22 protrudes from the circumferential wall of the barrel 21 and is provided with a stress point 221 capable of breaking. The inner wall of the barrel 21 is provided with a stop assembly for defining the upper and lower positions of the rod 22 and for detachably connecting the barrel 21 and the rod 22. The stop assembly allows the rod 22 to rotate.

[0079] When the rod body 22 is loaded, the rod body 22 can rotate around the axis of the rod body 22 relative to the cylinder 21, avoiding hard contact between the rod body 22 and the load-applying mechanism such as track III, thereby reducing friction loss of the rod body 22, extending the service life of the rod body 22, and reducing noise during operation of the rod body 22.

[0080] Furthermore, when the rod body 22 strikes a bolt or other debris during operation, it breaks at the stress point, preventing the load from being transferred to the mechanism that cooperates with the lever barrel 2 and causing damage to the mechanism, thereby extending the service life of the mechanism. Furthermore, the detachable connection between the barrel 21 and the rod body 22 allows for easy replacement of the rod body 22 if it breaks, reducing maintenance costs.

[0081] Therefore, the lever tube 2 can be used in conjunction with a mechanism that needs to bear a load and / or a mechanism with multiple loading directions, and has a wide range of adaptability.

[0082] Preferably, the stress point 221 is an annular groove provided on the central peripheral wall of the rod body 22 for ease of processing.

[0083] Furthermore, the upper portion of the rod body 22 can be inserted into the cylinder body 21 , and a bearing 23 is sleeved on the upper portion of the rod body 22 to support the rod body 22 to rotate relative to the cylinder body 21 .

[0084] Furthermore, the limiting assembly includes a first limiting groove 212 provided on the lower inner wall of the cylinder 21 and a second limiting groove 222 provided on the upper peripheral wall of the rod body 22. A first limiting member 213 is detachably provided in the first limiting groove 212 and is capable of abutting against the bottom of the bearing 23. A second limiting member 223 is detachably provided in the second limiting groove 222 and is capable of abutting against the top of the bearing 23.

[0085] By loading and unloading the first limiter 213 and the second limiter 223, the cylinder 21, the rod 22 and the bearing 23 can be easily loaded and unloaded, and the first limiter 213 and the second limiter 223 can also limit the upper and lower positions of the bearing 23, and further limit the upper and lower positions of the rod 22.

[0086] Preferably, the first limiting member 213 and the second limiting member 223 are both clips to facilitate assembly and disassembly.

[0087] Furthermore, two bearings 23 are provided to enhance the rotational support of the rod body 22. A bearing boss 224 is also provided on the upper peripheral wall of the rod body 22, located between the second limiting groove 222 and the stress point 221. Two bearings 23 are disposed on either side of the bearing boss 224, separating the two bearings 23 and preventing them from interlocking and wearing.

[0088] Example 2

[0089] This embodiment provides a collision protection device including the lever barrel of embodiment 1.

[0090] The collision protection device I is capable of operating along a first horizontal direction Z. It further comprises a housing 1, a trigger member 3, and a third stop member 4. The trigger member 3 is mounted on the housing 1 to carry and transmit the triggering action. The third stop member 4 is mounted on the housing 1 and is capable of limiting the position of the lever barrel 2, thereby maintaining the lever barrel 2 in an active state. The barrel 21 is rotatably connected to the housing 1 about a second horizontal direction perpendicular to the first horizontal direction Z. The lever barrel 2 and the trigger member 3 are arranged sequentially on the housing 1 along the operating direction of the collision protection device I.

[0091] When the trigger member 3 is triggered, the third limiting member 4 releases the limit on the lever tube 2, and the lever tube 2 can enter the failure state from the working state;

[0092] When the trigger member 3 is triggered and the lever tube 2 is still in the working state, the rod body 22 can be triggered to break at the stress point 221 of the rod body 22 .

[0093] In the present invention, the housing 1 serves as an assembly base for the lever barrel 2, the trigger member 3 and the third limit member 4, wherein the barrel body 21 of the lever barrel 2 is rotatably connected to the housing 1, and the rod body 22 of the lever barrel 2 is used to cooperate with the track III and drive the movement to run, and then drive the roller assembly to run. When the trigger member 3 is triggered, the third limit member 4 releases the swing position limit of the lever barrel 2, causing it to enter the failure state from the working state.

[0094] The lever barrel 2 operates in the following manner: the third stopper 4 constrains the lever barrel 2, maintaining it perpendicular to the transverse extension of the housing 1, and the rod body 22 is inserted into and engaged with track III. The lever barrel 2's failure state is defined by the third stopper 4 contacting the lever barrel 2. When an external force in a first horizontal direction Z is applied to the lever barrel 2, the lever barrel 2 swings to a position tilted relative to the transverse extension of the housing 1, and the rod body 22 disengages track III. The first horizontal direction Z represents the direction in which the collision protection device I travels with the sorting vehicle IV on the line II.

[0095] In the present invention, when debris such as bolts is present within track III, the trigger member 3 is triggered, and the third limit member 4 releases the swing restriction on the lever barrel 2, causing the lever barrel 2 to enter a disabled state from its working state. This in turn causes the rod body 22 of the lever barrel 2 to separate from track III, preventing the rod body 22 from continuing to move and being damaged and failing due to excessive load. This further prevents the rod body 22 from transmitting the load to the movement of the sorting vehicle IV and track III, causing damage and failure to the movement and / or track III. Furthermore, if the trigger member 3 fails to trigger and the lever barrel 2 remains in its working state, the collision protection device I continues to operate, and when the rod body 22 collides with debris, the stress point 221 of the rod body 22 can also break, causing the rod body 22 to separate from track III, thus preventing the rod body 22 from transmitting the load applied by the debris to the movement of the sorting vehicle IV and track III, causing damage and failure to the movement and / or track III.

[0096] Therefore, when objects such as bolts are present within Track III, this collision protection device I provides dual protection measures, including "the lever barrel 2 swings off Track III" and "the rod body 22 breaks off Track III." This enhances the protective effect of the collision protection device I on the sorting vehicle IV and Track III, effectively extending the service life of the sorting vehicle IV and Track III. Furthermore, because the rod body 22 and the barrel 21 are detachably connected, even if the rod body 22 breaks, it can be easily replaced. Furthermore, the rod body 22 is inexpensive, greatly improving maintenance convenience and reducing maintenance costs compared to the expensive repairs of the sorting vehicle IV and Track III.

[0097] It should be noted that the triggering methods of the trigger member 3 include, but are not limited to, image and mechanical contact. Mechanical contact is preferred in this embodiment because it allows for intuitive, rapid, and cost-effective recognition of objects such as bolts. The third limiter 4 can limit the swing of the lever barrel 2 by, but is not limited to, mechanical and magnetic limits. Mechanical limit is preferred in this embodiment.

[0098] Preferably, the housing 1 , the third triggering member 3 and the limiting member 4 can all be configured as metal parts.

[0099] Furthermore, the trigger member 3 includes a trigger portion 31, a hinge portion 32, and a shift fork 33 connected in sequence. The hinge portion 32 is connected to the housing 1 by rotation around the second horizontal direction. The third limiting member 4 includes a spring 41, and a pressure-bearing portion 42 and a latch 43 that are connected to each other. One end of the spring 41 abuts against the side wall of the housing 1. The pressure-bearing portion 42 abuts against the other end of the spring 41, and the shift fork 33 abuts against the side wall of the pressure-bearing portion 42 away from the spring 41. The upper portion of the rod body 22 is inserted into the cylinder 21, and the lower portion of the rod body 22 protrudes from the housing 1. A limiting hole 214 is provided on the cylinder 21.

[0100] During use, when the lever barrel 2 is in the operating state, the pressure-bearing portion 42 remains compressed by the spring 41, keeping the latch 43 engaged with the limiting hole 214. When the trigger member 3 is triggered, the shift fork 33 shifts the pressure-bearing portion 42, shortening the spring 41 and thereby releasing the latch 43 from the limiting hole 214, thereby releasing the swing restriction of the lever barrel 2. If the latch 43 does not release from the limiting hole 214 after the trigger member 3 is triggered and the lever barrel 2 remains in the operating state, the lever body 22 can be triggered, causing the lever body 22 to break at the stress point 221.

[0101] It should be noted that the working state corresponds to a state in which the latch 43 is engaged with the limiting hole 214, thereby keeping the lever barrel 2 perpendicular to the lateral extension direction of the housing 1. The failure state corresponds to a state in which the latch 43 is disengaged from the limiting hole 214, thereby causing the lever barrel 2 to tilt relative to the lateral extension direction of the housing 1.

[0102] The trigger portion 31 can be triggered by contact with debris such as a nut on track III, causing it to rotate in the opposite direction of the first horizontal direction Z, causing the shift fork 33 to rotate in the first horizontal direction Z. As the shift fork 33 rotates, it applies pressure to the pressure-bearing portion 42, driving the pressure-bearing portion 42 and the latch 43 to move synchronously. The pressure-bearing portion 42 compresses the spring 41, causing it to contract. Simultaneously, the latch 43 gradually disengages from the limiting hole 214 in the barrel 21, releasing the swing restriction on the lever barrel 2.

[0103] Specifically, the latch 43 and the limiting hole 214 both extend along the first horizontal direction Z, ensuring that when the trigger member 3 is triggered and swings, the latch 43 can be smoothly driven to disengage from the limiting hole 214. The latch 43 serves as both a rotation limiter for the lever barrel 2 and a guide for the movement of the spring 41. Specifically, the spring 41 is sleeved on the outside of the latch 43, and an additional through-hole can be provided in the housing 1 for the latch 43 to pass through, thereby preventing interference with the housing 1 when the latch 43 is driven by the pressure-bearing portion 42 and moves.

[0104] Furthermore, the collision protection device I further includes a rotating member 5 , which is connected to the housing 1 and keeps applying a torque to the cylinder 21 to cause the lever cylinder 2 to swing between the working state and the failure state.

[0105] In this embodiment, the rotating member 5 is a component that drives the lever barrel 2 from a working state to a failure state, and is preferably a purely mechanical component.

[0106] Under the action of the rotating member 5, when the limit member 4 releases the rotation restriction on the lever tube 2, the rotating member 5 can drive the lever tube 2 to swing and make the rod body 22 disengage from the track III, so that before the rod body 22 collides with nuts and other debris on the track III, it has already disengaged from the track III, ensuring that the lever tube 2 and / or the track III are not damaged.

[0107] Specifically, the rotating member 5 is a tension spring 51, and both ends of the tension spring 51 are hung on the tension spring connecting holes 219 on the outer shell 1 and the peripheral wall of the cylinder 21 respectively; or,

[0108] The rotating member 5 is a torsion spring, which is connected to the housing 1 and corresponds to the connection between the cylinder 21 and the housing 1 . Two ends of the torsion spring abut against the outer walls of the housing 1 and the cylinder 21 , respectively.

[0109] It should be noted that the rotating part 5 is configured as a tension spring 51 and when the lever cylinder 2 is in the working state, the tension spring 51 must remain stretched to store sufficient elastic potential energy to pull the lever cylinder 2 into operation; when the rotating part 5 is configured as a torsion spring and when the lever cylinder 2 is in the working state, the torsion spring must also remain twisted to store sufficient elastic potential energy to pull the lever cylinder 2 into operation.

[0110] Regardless of whether a tension spring 51 or a torsion spring is used, the rotating member 5 forms a purely mechanical traction component, which has many advantages such as short response time, stable operation, and low cost. Since the tension spring 51 is less expensive to install than the torsion spring, the rotation member 5 is preferably a tension spring 51 in this embodiment.

[0111] Furthermore, the collision protection device I further includes a connecting block 6, which is fixedly connected to the housing 1. The latch 43 penetrates and is slidably connected to the connecting block 6.

[0112] The connecting block 6 is provided to limit the sliding trajectory of the latch 43 and the pressure-bearing portion 42, thereby ensuring that the latch 43 can accurately slide along the first horizontal direction Z, so as to ensure that it can accurately and stably engage with the limiting hole A in a force-free manner or establish a matching relationship.

[0113] Specifically, the connecting block 6 can be configured as a metal block, which is located inside the housing 1 and placed between the connecting block 6 and the spring 41 .

[0114] Furthermore, the housing 1 includes a first cavity and a second cavity, which are separated by a connecting block 6 and extend along a first horizontal direction Z. The connecting portion 21 is hinged to the first cavity, and the spring 41 is disposed in the second cavity.

[0115] In this embodiment, the housing 1 is divided into a first cavity and a second cavity by the connecting block 6. The first cavity and the second cavity extend along the first horizontal direction Z. The connecting portion 21 and the spring 41 are respectively arranged in the first space and the second space, which saves the setting space of the lever tube 2 and the spring 41 and makes it easier to arrange the trigger member 3. After the trigger member 3 is arranged, the fork 33 included in the trigger member 3 is also easier to trigger the pressure-bearing portion 42 to make the pin 43 disengage from the limiting hole 214.

[0116] Example 3

[0117] This embodiment further defines the lever barrel 2 based on the embodiments 1 and 2. The lever barrel 2 also includes the following configurations:

[0118] The axis of the limiting hole 214 is parallel to the first horizontal direction Z.

[0119] A notch 215 extending from the top of the cylinder 21 to the limiting hole 214 is provided, which is inclined to the axial direction of the cylinder 21 , so as to avoid collision with other structures of the collision protection device I (such as the connecting block 6 ) when the lever cylinder 2 rotates around the second horizontal direction.

[0120] A gasket 216 coaxial with the limiting hole 214 is provided on the peripheral wall of the cylinder 21 to enhance the use strength of the limiting hole 214 that needs to cooperate with the latch 43.

[0121] The peripheral wall of the cylinder 21 is provided with a pin connecting hole 217 for passing a pin to be rotatably connected to the housing 1. The axis of the pin connecting hole 217 is parallel to the second horizontal direction, that is, the axis of the pin connecting hole 217 and the axis of the limiting hole 214 are perpendicularly arranged.

[0122] The position where the pin connection hole 217 is provided on the peripheral wall of the cylinder 21 is a flat surface 218 for fitting with the outer shell 1, so as to facilitate connecting the cylinder 21 to the outer shell 1.

[0123] Preferably, the inner diameter of the upper portion of the barrel 21 is larger than that of the lower portion. A retaining hole 214 and a pin connection hole 217 are provided in the upper portion of the barrel 21 to enhance the stability of its connection with the housing 1 and its mating with the latch 43.

[0124] Example 4

[0125] This embodiment provides a courier sorting system, which, in addition to having all the technical solutions of any of the above embodiments, further has the following technical solutions:

[0126] The express sorting system further includes line body II, track III and sorting vehicle IV.

[0127] Track III is provided on line body II. Sorting vehicle IV runs along the extension direction of line body II. Collision protection device I is slidably connected to sorting vehicle IV along the width direction of sorting vehicle IV. The rod body 22 of the lever cylinder 2 in the working state can contact and cooperate with track III.

[0128] When in use, when the trigger member 3 is triggered by debris on the track III, the lever tube 2 swings from the working state to the failure state;

[0129] When the trigger member 3 is triggered by debris on the track III and the lever tube 2 is still in the working state, the rod body 22 can be triggered by the debris on the track III, so that the stress point 221 of the rod body 22 breaks.

[0130] Specifically, the sorting vehicle IV includes a movement and a roller assembly. The power input end of the roller assembly is driven and connected to the power output end of the movement. The courier is placed on the platform formed by the roller assembly, and the collision protection device I is connected to the power input end of the movement.

[0131] In this embodiment, Line II is configured as a loop, and Track III is also arranged in a loop along Line II. Track III comprises multiple undulating sections. When sorting vehicle IV reaches a corresponding undulating section, the lever cylinder 2 is guided by the undulating section and moves along the width of Line II, inputting power to the mechanism, thereby operating the roller assembly of sorting vehicle IV and completing the express delivery sorting operation.

[0132] Specifically, the movement can be set as a gear rack assembly. By connecting the collision protection device I to the rack, when the collision protection device I slides along the width direction of the sorting vehicle IV, it drives the rack to run and then drives the gear that matches the rack to run. The gear can transmit the torque to the roller assembly through the transmission assembly.

[0133] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature.
