Description

Technical Field

[0001] This application relates to the field of unmanned delivery vehicle technology, and in particular to an arrival detection device. Background Technology

[0002] In order to make delivery more intelligent, companies in the logistics industry are trying out unmanned delivery services. Unmanned delivery vehicles are a product that has emerged in response to the current last-mile delivery market and the development of autonomous driving. They are used to complete the transfer and delivery of cages and boxes.

[0003] To improve the efficiency of loading and unloading cages, unmanned delivery vehicles have begun to use a tipping mechanism to quickly transport cages onto the vehicle. The specific workflow involves pushing the cage into the tipping mechanism, which is then activated to tip the cage onto the vehicle. Currently, the tipping mechanism of unmanned delivery vehicles lacks a device to detect whether the cage has moved into place. If the cage is not fully pushed into the tipping mechanism, it may fall during the tipping process, posing a safety hazard. Utility Model Content

[0004] The purpose of this application is to provide a positioning detection device to solve the technical problem that the existing unmanned delivery vehicle's tilting mechanism lacks a device to detect whether the cage has moved into position. If the cage is not fully pushed into the tilting mechanism, the cage may fall during the tilting process, posing a safety hazard.

[0005] To achieve the above objectives, one technical solution adopted in this application is:

[0006] A positioning detection device is provided, comprising:

[0007] A flip-up pressure plate is rotatably configured, and the flip-up pressure plate includes a pressure-receiving surface and a driving surface arranged opposite to each other, the pressure-receiving surface being used to contact the detection target;

[0008] A limiting baffle is arranged on one side of the driving surface of the flipping pressure plate, and a limiting groove is arranged inside the limiting baffle;

[0009] A limit switch includes a contact disposed in the limit groove, wherein the diameter of the contact is smaller than the width of the limit groove;

[0010] A transmission unit is arranged between the limit switch and the flip plate, and the transmission unit is used to drive the limit baffle to move when the flip plate rotates.

[0011] The limiting baffle includes an in-position posture and an out-of-position posture. When in the in-position posture, the groove wall of the limiting groove contacts the contact to trigger the limiting switch. When in the out-of-position posture, a gap is formed between the groove wall of the limiting groove and the contact.

[0012] In one or more embodiments, the limit switch further includes a swing arm, which is rotatably configured and at least partially embedded in the limit groove. The contact is arranged at the end of the swing arm embedded in the limit groove. When the limit baffle moves, it drives the swing arm to rotate, thereby switching between the in-position posture and the out-of-position posture.

[0013] In one or more embodiments, the limit switch further includes a switch base arranged next to the limit baffle, the swing arm having a strip-shaped mounting hole extending along its length, and the swing arm being rotatably mounted on the switch base by a bolt passing through the strip-shaped mounting hole.

[0014] In one or more embodiments, the swing arm includes a mounting section and a connecting section, the contact is disposed at the end of the connecting section, the width of the mounting section is greater than the diameter of the contact, and the width of the connecting section gradually decreases in the direction pointing to the contact, so that symmetrical inclined surfaces are formed on both sides of the connecting section.

[0015] In one or more embodiments, the transmission unit includes:

[0016] A sleeve is arranged on one side of the driving surface of the flipping pressure plate, and the sleeve is rotatably set;

[0017] The push rod has one end hinged to the drive surface and the other end passing through the sleeve and connected to the limiting baffle.

[0018] In one or more embodiments, a sleeve retainer is further included, the sleeve retainer being arranged on one side of the drive surface of the flip-over pressure plate, and the sleeve being rotatably mounted on the sleeve retainer by means of a pin.

[0019] In one or more embodiments, the transmission unit further includes a compression spring sleeved on the push rod and located between the flipping pressure plate and the sleeve.

[0020] In one or more embodiments, the drive surface is provided with an ear seat, the end of the push rod is provided with a connector that matches the ear seat, and the push rod is hinged to the flipping pressure plate by a pin passing through the ear seat and the connector.

[0021] In one or more embodiments, a pressure plate fixing plate is further included, the pressure plate fixing plate being arranged next to the flipping pressure plate, one end of the flipping pressure plate being hinged to the pressure plate fixing plate via a rotating shaft.

[0022] In one or more embodiments, the limiting baffle is a U-shaped plate structure, and the limiting groove is formed inside the limiting baffle.

[0023] The advantages of this application, which differ from existing technologies, are:

[0024] When the flipping pressure plate of this application rotates under the pressure of the detection target, it drives the limit baffle to move through the transmission unit. The limit baffle has a limit switch contact arranged in the limit groove. When the detection target has not moved into place, a gap is formed between the limit groove wall and the contact. When the detection target moves into place, the limit groove wall contacts the contact and triggers the limit switch, which can send an position signal to realize the position detection.

[0025] When this application is applied to the tipping mechanism of an unmanned delivery vehicle, the tipping plate can be driven to rotate when the cage is pushed in. When the cage is pushed into place, the limit baffle can contact the contactor to trigger the limit switch to send an in-place signal, thereby detecting whether the cage has been pushed into place. This ensures that the cage is installed in place during the tipping operation and avoids safety hazards. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0039] To address the safety hazard posed by the lack of a cage placement detection device in the current unmanned delivery vehicle's tipping mechanism, the applicant provides a placement detection device applicable to the tipping mechanism. This device sends a placement signal when the cage is pushed into place, ensuring that the tipping mechanism performs the tipping operation only after the cage is properly installed, thus avoiding safety hazards.

[0040] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of one embodiment of the detection device of this application. Figure 2 This is an exploded structural diagram of one embodiment of the detection device of this application.

[0041] like Figure 1 and Figure 2 As shown, the positioning detection device includes a flipping pressure plate 100. The flipping pressure plate 100 is rotatably configured and includes a pressure-receiving surface 101 and a driving surface 102 arranged opposite to each other, wherein the pressure-receiving surface 101 is used to contact the detection target.

[0042] In practical applications, the flipping pressure plate 100 can be arranged in the loading space of the flipping mechanism of the unmanned delivery vehicle. When the cage moves into the loading space, it can contact the pressure surface 101 and drive the flipping pressure plate 100 to rotate.

[0043] Specifically, in this embodiment, the positioning detection device also includes a pressure plate fixing plate 200 for mounting the flip pressure plate 100. One end of the flip pressure plate 100 can be mounted on the pressure plate fixing plate 200 through a rotating shaft 300 that passes through the pressure plate fixing plate 200 and the flip pressure plate 100, thereby realizing the hinged mounting of the flip pressure plate 100.

[0044] A limiting baffle 400 is arranged on one side of the driving surface 102 of the flipping pressure plate 100, and a limiting groove 401 is arranged inside the limiting baffle 400.

[0045] A transmission unit 500 is provided between the limiting baffle 400 and the flipping pressure plate 100. The transmission unit 500 is used to drive the limiting baffle 400 to move when the flipping pressure plate 100 rotates.

[0046] A limit switch 600 is also arranged on one side of the driving surface 102 of the flip plate 100. The limit switch 600 includes a contact 601 arranged in the limit groove 401. The diameter of the contact 601 is smaller than the width of the limit groove 401.

[0047] The limit baffle 400 includes an in-position posture and an out-of-position posture. When in the in-position posture, the groove wall of the limit groove 401 contacts the contact 601 to trigger the limit switch 600. When in the out-of-position posture, a gap is formed between the groove wall of the limit groove 401 and the contact 601.

[0048] Understandably, when the flipping pressure plate 100 is rotated under pressure, it can drive the limit baffle 400 to move through the transmission unit 500, thereby switching the limit baffle 400 between the in-position and non-in-position postures. When the limit baffle 400 is in the in-position posture, it means that the flipping pressure plate 100 has been rotated to the in-position under pressure, that is, the detection target in contact with the flipping pressure plate 100 has moved to the in-position.

[0049] In this embodiment, the limiting baffle 400 has a U-shaped plate structure, and a limiting groove 401 is formed inside the limiting baffle 400. In other embodiments, the limiting baffle 400 may also adopt other structural forms, as long as it can realize the cooperation between the limiting groove 401 and the contact 601 to switch between the in-position and non-in-position states.

[0050] In this embodiment, the transmission unit 500 includes a sleeve 501 and a push rod 502. The sleeve 501 is arranged on one side of the driving surface 102 of the flipping pressure plate 100 and is rotatably mounted.

[0051] One end of the push rod 502 is hinged to the drive surface 102, and the other end passes through the sleeve 501 and is connected to the limit baffle 400.

[0052] When the flipping pressure plate 100 is rotated under pressure, it can drive the push rod 502 to move along the sleeve 501, and simultaneously drive the limit baffle 400 to move.

[0053] In this embodiment, the sleeve 501 is installed via a sleeve fixing bracket 503, which is located on one side of the driving surface 102 of the flip-over pressure plate 100. The sleeve 501 is rotatably mounted on the sleeve fixing bracket 503 via a pull ring indexing pin 504. In other embodiments, the sleeve 501 can also be installed in other ways, as long as the sleeve 501 can be rotatably installed, all of which can achieve the effect of this embodiment.

[0054] In this embodiment, the drive surface 102 is provided with an ear seat 103, and the end of the push rod 502 is provided with a connector 505 that matches the ear seat 103. The push rod 502 is hinged to the flipping pressure plate 100 through a pin 506 passing through the ear seat 103 and the connector 505. In other embodiments, other structures can be used to achieve the hinged connection between the push rod 502 and the flipping pressure plate 100, all of which can achieve the effect of this embodiment.

[0055] In order to enable the flipping pressure plate 100 to reset when it loses the pressure of the detection target, the transmission unit 500 in this embodiment also includes a compression spring 507. The compression spring 507 is sleeved on the push rod 502 and is located between the flipping pressure plate 100 and the sleeve 501.

[0056] The structure of the limit switch 600 in this embodiment is described in detail below. The limit switch 600 in this embodiment also includes a swing arm 602 and a switch base 603.

[0057] The switch base 603 is arranged next to the limit baffle 400. One end of the swing arm 602 is rotatably mounted on the switch base 603, and the swing arm 602 is at least partially embedded in the limit groove 401. The contact 601 is arranged at the end of the swing arm 602 embedded in the limit groove 401. When the limit baffle 400 moves, it drives the swing arm 602 to rotate, so as to switch between the in-position and non-in-position states.

[0058] Please see Figure 3 , Figure 3 This is a schematic diagram illustrating the movement of the limit switch and limit baffle from their non-positioned to their positioned state in this application. Figures 1 to 3 As shown, when the flipping pressure plate 100 is rotated under pressure, the push rod 502 can drive the limit baffle 400 to rotate. The limit baffle 400 can first contact the swing arm 602 and drive the swing arm 602 and the contact 601 to rotate synchronously. Until the flipping pressure plate 100 rotates to the position, the limit baffle 400 and the contact 601 rotate to the position of mutual contact. At this time, the limit switch 600 is triggered to send an end signal to realize the end detection.

[0059] In order to make the height of the contact 601 adjustable to adapt to the needs of different application scenarios, in this embodiment, the swing arm 602 is provided with a strip-shaped mounting hole 6021 extending along the length direction, and the swing arm 602 is rotatably mounted on the switch base 603 by bolts passing through the strip-shaped mounting hole 6021.

[0060] The height of the contact 601 can be adjusted by adjusting the position of the bolt in the strip mounting hole 6021, thereby adapting to the needs of different application scenarios.

[0061] Furthermore, to facilitate contact between the contact 601 and the wall of the limiting groove 401, the swing arm 602 includes a mounting section 6022 and a connecting section 6023. The contact 601 is arranged at the end of the connecting section 6023. The width of the mounting section 6022 is greater than the diameter of the contact 601. The width of the connecting section 6023 gradually decreases in the direction pointing towards the contact 601, so that symmetrical inclined surfaces are formed on both sides of the connecting section 6023. Through the inclined surface design of the connecting section 6023, a clearance space for the limiting baffle 400 can be formed on the swing arm 602, which helps the contact 601 and the wall of the limiting groove 401 to make contact when in the positioned position.

[0062] Please see Figure 4 , Figure 4 This is a structural schematic diagram of one embodiment of the positioning detection device of this application in its working state. For example... Figure 4 As shown, when the flip plate 100 is pressed into position, the limit baffle 400 and the contact 601 move to the position of mutual contact. At this time, the limit switch 600 is triggered to send an in-position signal to realize the in-position detection.

[0063] Specifically, when applied to the tipping mechanism of an unmanned delivery vehicle, when the tipping plate 100 is pushed into place and driven into position by the cage, the limit switch 600 sends a position signal to the control unit of the unmanned delivery vehicle. After receiving the position signal, the control unit of the unmanned vehicle can drive the tipping mechanism to start tipping the cage, thereby ensuring that the cage is installed in place during the tipping operation and avoiding safety hazards.

[0064] When the cage is removed, the flipping pressure plate 100 can be reset under the elastic force of the compression spring 507, so as to perform positioning detection in the next operation.
