Description

Technical Field

[0001] This utility model relates to a garbage truck bin-hanging mechanism, belonging to the technical field of devices for garbage collection vehicles with garbage unloading containers. Background Technology

[0002] The bin-hanging mechanism is a device on garbage trucks used to hang garbage bins to achieve bin lifting and garbage dumping. The bin-hanging mechanism usually includes a hanging plate and a pressure plate located above the hanging plate. The upper part of the hanging plate has multiple claws for inserting garbage bin hooks. When in use, after the hanging plate hangs the garbage bin, it drives the garbage bin to rise and press against the pressure plate above. The pressure plate and the hanging plate work together to clamp the garbage bin, so as to achieve stable lifting and tipping of the garbage bin.

[0003] For example, Chinese utility model patent CN217111114U discloses a dynamic automatic weighing device for garbage trucks, including a guide rail, a movable frame, and a drive mechanism for controlling the lifting and lowering of the movable frame. The upper end of the movable frame is equipped with an upper pressure plate, and a movable mounting frame is also provided on the movable frame. The mounting frame is equipped with a weighing plate and a weighing sensor. When the weighing plate lifts the garbage bin, the weighing sensor weighs the garbage bin. A proximity switch is located at the upper end of the mounting frame. When the weighing plate lifts the garbage bin to near the upper pressure plate, the proximity switch is triggered, causing the motion sensor to perform a flip-counting motion. When the bin rises to the top of the guide rail, it is emptied.

[0004] However, the aforementioned proximity switch is an externally mounted device without any protective measures. When dumping garbage, various dust, dirty liquids, grease and other contaminants will splash onto the proximity switch. Over time, this will cause a lot of dirt to accumulate on the proximity switch. This dirt not only affects the sensing effect of the proximity switch, but also corrodes the proximity switch, greatly increasing the failure rate of the proximity switch. Utility Model Content

[0005] The purpose of this utility model is to provide a garbage truck bin-hanging mechanism to solve the problems in the prior art where the proximity switch is externally installed, which makes it easy for dirt to adhere and thus affect the sensing effect of the proximity switch, as well as corrode the proximity switch and greatly increase the failure rate of the proximity switch.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A garbage truck bin-hanging mechanism includes a hanging plate and a pressure plate located above the hanging plate. The upper end of the hanging plate is provided with a plurality of hanging claws for inserting garbage bin hanging ears. At least one hanging claw is equipped with a proximity switch for inserting into the garbage bin hanging ear together with the hanging claw. The proximity switch is concealed in the hanging claw and only the upper sensing surface is exposed and does not protrude from the top surface of the hanging claw. The pressure plate is provided with a triggering structure for cooperating with the proximity switch to trigger the proximity switch.

[0008] The beneficial effects of the above technical solution are as follows: This utility model is an invention that changes the relationship between elements, altering the installation position of the proximity switch. The proximity switch is installed on the hook and inserted into the trash can's hanging ear along with the hook. Because the proximity switch is concealed within the hook, with only the upper sensing surface exposed and not protruding from the top surface of the hook, when the hook plate is attached to the trash can, the hook and the trash can's hanging ear completely enclose the proximity switch, effectively protecting it and preventing dirt from adhering to it during trash disposal, thus ensuring the proximity switch's sensing effect and lifespan. Simultaneously, since the trash can's hanging ear covers the upper sensing surface of the proximity switch, a triggering structure is provided on the pressure plate to ensure that the proximity switch is triggered when the hook plate and trash can rise to a certain level, guaranteeing the normal operation of the proximity switch.

[0009] Furthermore, the mounting plate includes a mounting plate body and multiple claw bodies connected to the upper end of the mounting plate body. The claw with a proximity switch includes a claw body and a mounting block fixed on the claw body. The proximity switch is fixed on the mounting block, and the sensing surface at the upper end of the proximity switch protrudes from the mounting block and does not protrude from the top surface of the mounting block.

[0010] Furthermore, the mounting block is L-shaped, including a horizontal section and a vertical section connected to the horizontal section. The horizontal section overlaps on the upper surface of the corresponding claw body. The proximity switch is fixed on the horizontal section. The upper part of the proximity switch is located in the middle of the horizontal section, and the lower part is located between the vertical section and the claw body. The claw body is provided with a clearance groove for avoiding the lower part of the proximity switch.

[0011] Furthermore, the vertical section is located on the front side of the claw body facing the trash can, a wire is connected to the proximity switch, and the claw body is provided with a connecting clearance groove and the space behind the hanging plate so that the wire can pass through and extend into the outlet hole on the back of the hanging plate.

[0012] Furthermore, the rear side of the mounting plate body is provided with an extension groove that communicates with the cable outlet and extends downward. The mounting plate also includes a mounting plate fixed to the rear side of the mounting plate body and used for installing the weighing sensor. The mounting plate has a notch at the position corresponding to the extension groove, and the notch and the extension groove together form a cable passage hole for the wire to pass through.

[0013] Furthermore, the vertical section has a groove on the side facing the claw body to avoid the lower part of the proximity switch.

[0014] Furthermore, only one of the multiple hooks is equipped with a proximity switch. In addition to the hook body with the mounting block, the other hook bodies are respectively fixed with reinforcing blocks for inserting into the trash can hook ears together with the hook body. The top surface of each reinforcing block is flush with the top surface of the mounting block.

[0015] Furthermore, the vertical section is fixed to the claw body by screws.

[0016] Furthermore, the proximity switch is mounted on the outermost of the multiple claws.

[0017] Furthermore, the triggering structure is a magnet mounted on the pressure plate. Attached Figure Description

[0028] To address the technical problems existing in the prior art, the basic concept of this utility model is to conceal the proximity switch within the hanging claw, with only the upper sensing surface exposed above the claw and not protruding from its top surface. The claw and the claw are then inserted into the trash can's hanging ear. The claw and the trash can's hanging ear work together to effectively protect the proximity switch, preventing dirt from adhering to the proximity switch during the trash dumping process.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] The implementation method of the garbage truck bin-hanging mechanism in this utility model is as follows:

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the garbage truck's bin-hanging mechanism includes a hanging plate 10 and a pressure plate 20 located above the hanging plate 10. The upper end of the hanging plate 10 is equipped with multiple claws for inserting garbage bin hooks. One of the claws is fitted with a proximity switch 17 for inserting into the garbage bin hook along with the claw. The proximity switch 17 is concealed within the claw, with only its upper sensing surface exposed and not protruding (flat or slightly lower) from the top surface of the claw. Thus, when the hanging plate hooks onto the garbage bin, the claw and the garbage bin hook completely enclose the proximity switch 17, effectively protecting it and preventing dirt from adhering to it during garbage dumping, thus ensuring the sensing effect and lifespan of the proximity switch 17.

[0032] Meanwhile, since the trash can hanging ears cover the sensing surface at the top of the proximity switch 17, a triggering structure is provided on the pressure plate 20 to cooperate with the proximity switch 17, so as to ensure that the proximity switch 17 can be triggered when the hanging plate 10 and the trash can rise to a certain level, thus ensuring the normal use of the proximity switch 17.

[0033] Specifically, in this embodiment, the mounting plate 10 includes a mounting plate body 11 and multiple claw bodies 12 connected to the upper end of the mounting plate body 11. The mounting plate body 11 and each claw body 12 are machined from a single piece of sheet metal. The claw with the proximity switch 17 includes a claw body 12 and a mounting block 13 fixed to the claw body 12. The proximity switch 17 is fixed to the mounting block 13, and the sensing surface at the upper end of the proximity switch 17 protrudes from the mounting block 13 but does not protrude from the top surface of the mounting block 13. By having the claw body 12 and the mounting block 13 together form the claw, the structural strength of the claw can be improved, preventing deformation during use. Simultaneously, the proximity switch 17 can be first fixed to the mounting block 13 and then together fixed to the claw body 12, facilitating the assembly of the proximity switch 17.

[0034] Furthermore, in this embodiment, the mounting block 13 is L-shaped. Combined with... Figure 3, Figure 6 , Figure 8 and Figure 9 As shown, the mounting block 13 includes a horizontal section 131 and a vertical section 132 connected to the horizontal section 131. The horizontal section 131 overlaps the upper end surface of the corresponding claw body 12. The proximity switch 17 is fixed on the horizontal section 131, and a fixing hole for fixing the proximity switch 17 is provided on the horizontal section 131. The top surface of the horizontal section 131 is the top surface of the claw. The upper part of the proximity switch 17 is located in the horizontal section 131, and the sensing surface at the upper end protrudes from the horizontal section 131 but does not protrude from the top surface of the horizontal section 131. The lower part of the proximity switch 17 is located between the vertical section 132 and the claw body 12. A clearance groove 121 for avoiding the lower part of the proximity switch 17 is provided on the claw body 12. Thus, through the structural design of the mounting block 13, the proximity switch 17 is easily fixed to the mounting block 13, and part of it is hidden inside the mounting block 13; at the same time, through the design of the clearance groove 121, the remaining part of the proximity switch 17 is easily hidden between the mounting block 13 and the claw body 12.

[0035] The proximity switch 17 in this embodiment includes a switch body 171 and a locking nut 172. The switch body 171 is cylindrical with external threads on its surface, and the fixing hole on the horizontal section 131 is an internally threaded hole so that the switch body 171 can be directly screwed in. The lower part of the switch body 171 and the locking nut 172 are located below the horizontal section 131. By tightening the locking nut 172, the position of the switch body 171 can be fixed to prevent the switch body 171 from loosening. Furthermore, two locking nuts 172 are provided to improve the anti-loosening effect. In other embodiments, depending on the specific form of the proximity switch 17, the housing of the proximity switch 17 and the fixing hole can also be connected by a snap-fit ​​connection. For example, the housing of the proximity switch 17 has a protrusion, and the wall of the fixing hole has a groove that engages with the protrusion. Of course, in other embodiments, the proximity switch 17 can also be glued and fixed in the fixing hole.

[0036] Therefore, in this embodiment, the clearance groove 121 avoids the lower part of the cylinder of the switch body 171 and the two locking nuts 172. In other embodiments, when the proximity switch 17 has a different structure, it avoids the part of the proximity switch 17 exposed below the horizontal section 131.

[0037] In this embodiment, the horizontal section 131 is relatively short, and the installation position of the switch body 171 is relatively close to the vertical section 132. Therefore, a groove 134 is provided on the side of the vertical section 132 facing the claw body 12 to avoid interference between the lower part of the proximity switch 17 and the vertical section 132, thus preventing the installation of the proximity switch 17 from being affected. Specifically, in this embodiment, the groove 134 facilitates the screwing of the switch body 171 onto the horizontal section 131 and the tightening of the locking nut 172. Therefore, the groove 134 is a short blind groove. In other embodiments, the groove 134 can also extend downwards to penetrate the lower end face of the vertical section 132.

[0038] Furthermore, in this embodiment, a wire 18 is connected to the proximity switch 17, so the clearance groove 121 not only avoids the lower part of the proximity switch 17 but also avoids the wire 18. Meanwhile, the vertical section 132 is located on the front side of the claw body 12 facing the trash can, so the claw body 12 has a connecting clearance groove 121 and the rear space of the hanging plate for the wire 18 to pass through and extend into the rear of the hanging plate through an outlet hole 122. This allows the other end of the wire 18 to be connected to a signal receiving device via a connector, so that after the proximity switch 17 is triggered, a trigger signal can be transmitted to the signal receiving device to initiate other automatic control processes (such as weighing initiated by a weighing sensor).

[0039] It should be noted that the wire 18 has an insulating outer sheath, which has good corrosion resistance. Even if it is exposed to the outside and becomes contaminated with oil, it will not affect normal use. Of course, in other embodiments, the proximity switch 17 can be a switch with a built-in signal transmitting module. In this case, there is no wire 18, and there is no need to set up a wire outlet hole 122.

[0040] In this embodiment, the clearance groove 121 extends a certain length in the vertical direction. The length of the clearance groove 121 is greater than the length of the groove 134. The upper end of the clearance groove 121 penetrates the upper end face of the claw body 12. The wire outlet hole 122 is set on the bottom wall of the clearance groove 121 at the lower end, so that the wire 18 has a certain length in the clearance groove 121, avoiding excessive bending of the wire 18. Of course, in other embodiments, the clearance groove 121 can also be shorter, with a length equal to the length of the groove 134.

[0041] The lower end face of the vertical section 132 is lower than the lower end face of the clearance groove 121, so that the vertical section 132 can completely cover the clearance groove 121. At the same time, the horizontal section 131 covers the upper opening of the clearance groove 121. This provides good protection and prevents dirt from entering. The rear end face of the horizontal section 131 is flush with the rear side of the hook body 12. The overall structure is compact and facilitates the insertion of the hook into the trash can's hanging ear.

[0042] Furthermore, to facilitate the installation and removal of the mounting block 13, in this embodiment, the vertical section 132 is fixed to the claw body 12 by screws 15. Specifically, the claw body 12 is provided with screw holes 123 for the screws 15 to pass through. There are four screw holes 123, arranged in pairs on the left and right sides of the clearance groove 121. At the same time, the vertical section 132 is provided with threaded holes 133 that mate with the screws 15, that is, the screws 15 are installed from back to front, and the screw holes 123 are countersunk holes. Of course, in other embodiments, the screw holes can also be set on the vertical section 132, and the threaded holes can be set on the claw body 12. In this case, the screws 15 are installed from front to back, and the screw holes are countersunk holes to avoid the head of the screws 15 protruding and affecting the smooth hanging of the trash can or damaging the trash can hooks.

[0043] In other embodiments, if the size is sufficient, the horizontal segment 131 can also be fixed to the claw body 12 with screws to achieve the fixation between the mounting block 13 and the claw body 12. In this case, the horizontal segment 131 has screw holes, and the screw holes are countersunk holes. The claw body 12 has vertical threaded holes. Of course, in other embodiments, the mounting block 13 and the claw body 12 can also be fixed by adhesive bonding or welding.

[0044] like Figure 4 , Figure 5 and Figure 8 As shown, the mounting plate 10 also includes a mounting plate 16 fixed to the rear side of the mounting plate body 11 for mounting the load cell 19. The mounting plate 16 is horizontally arranged and has the same width as the mounting plate body 11. The mounting plate 16 is fixed to the upper end of the mounting plate body 11. Therefore, a notch 161 is provided on the mounting plate 16 to facilitate wiring. At the same time, an extension groove 111 communicating with the outlet hole 122 and extending downward is provided on the rear side of the mounting plate body 11. The notch 161 and the extension groove 111 are arranged opposite to each other, and the lower end of the extension groove 111 is located below the notch 161. In this way, after the wire 18 passes through the outlet hole 122, it passes through the wire hole formed by the extension groove 111 and the notch 161 and the extension groove 111, which facilitates wiring and avoids damage to the wire 18. Of course, the opening of the outlet hole 122 is chamfered, and the notch 161 is a U-shaped notch to improve the protection of the wire 18. In other embodiments, the extension slot may not be required, and the wire 18 can pass directly through the notch 161 after exiting the wire hole 122.

[0045] Furthermore, since the weighing sensor 19 is located in the middle of the mounting plate 16, and the rear side of the middle of the hanging plate body 11 is also provided with a mounting bracket for connecting with the lifting frame, in order to facilitate wiring and the installation of screws 15, in this embodiment, the proximity switch 17 is installed on the outermost of the multiple hanging claws, that is, the mounting block 13 is fixed on the outermost hanging claw body 12. In this embodiment, it is fixed on the leftmost hanging claw body 12. In other embodiments, it can also be fixed on the rightmost hanging claw body 12. Of course, in other embodiments, if there is no interference, it can also be fixed on the middle hanging claw body 12.

[0046] In other embodiments, even if the mounting block 13 is fixed on the outermost claw body 12, if the left and right width of the mounting plate 16 is relatively narrow and the wire 18 can pass through the side of the mounting plate 16, then there is no need to set a notch on the mounting plate 16. In this case, an extension groove can be set on the hanging plate body 11, or it can be left unset.

[0047] In this embodiment, as Figures 1-3 , Figure 7 As shown, in addition to the hook body 12 with the mounting block 13 fixed, each of the other hook bodies 12 is fixed with a reinforcing block 14 for inserting into the trash can hook ear together with the hook body 12. The hook body 12 and the corresponding reinforcing block 14 together constitute the hook, so that the structural strength of all hooks is guaranteed, which is conducive to improving the service life of the hanging plate 10.

[0048] Specifically, the reinforcing block 14 is located on the front side of the corresponding hook body 12, ensuring that the front and rear sides of each hook are in the same plane, facilitating their insertion into the trash can's hanging ear. Simultaneously, the top surface of the reinforcing block 14 is flush with the top surface of the hook body 12 it belongs to, and also flush with the top surface of the horizontal section 131 of the mounting block 13. In other words, the reinforcing block 14 is square-shaped with a simple structure. The top surface of the hook body 12 to which the mounting block 13 is fixed is lower than the top surfaces of the other hook bodies 12. After fixing the mounting block 13, the top surfaces of all hooks are in the same plane.

[0049] In other embodiments, each reinforcing block 14 can be located on the rear side of the corresponding claw body 12. In this case, the vertical section 132 of the mounting block 13 is located on the rear side of the corresponding claw body 12 to ensure that the front and rear sides of each claw are still in the same plane. At this time, the groove 134 on the mounting block 13 faces forward, and the clearance groove 121 on the claw body 12 faces backward. If the proximity switch 17 is connected to a wire 18, the wire outlet is opened at the lower end of the groove 134, connecting the groove 134 and the space behind the vertical section 132.

[0050] Of course, in other embodiments, the mounting block 13 may not be L-shaped, but rather a square block structure. The top surface of the mounting block 13 is flush with the top surface of the corresponding claw body 12. In this case, the fixing hole on the mounting block 13 for fixing the proximity switch 17 is a stepped hole with a smaller diameter at the top and a larger diameter at the bottom. The smaller diameter hole at the top is a threaded hole for threaded connection with the switch body 171, and the larger diameter hole at the bottom is used to accommodate the lower part of the switch body 171 and the locking nut 172, and the hole diameter can meet the screwing operation of the switch body 171 and the locking nut 172. In this case, the mounting block 13 can be fixed to the rear side of the corresponding claw body 12, just like the other reinforcing blocks 14. The wire 18 exits directly from the lower end of the stepped hole, without the need to provide a wire exit hole on the claw body 12. Of course, the mounting block 13 and the other reinforcing blocks 14 can be fixed to the front side of the corresponding claw body 12. In this case, a wire exit hole needs to be provided on the claw body 12 so that the wire 18 can be led out to the rear side of the mounting plate body 11.

[0051] The pressure plate 20 includes a pressure plate body 21 and a magnet 22 fixed on the pressure plate body 21. The magnet 22 is arranged vertically with the sensing surface at the upper end of the proximity switch 17, forming the aforementioned triggering structure. In this embodiment, the proximity switch 17 is a reed switch type with an internal mechanical structure. It is triggered by the magnetic force of the magnet 22, requiring no power supply and making it more convenient to use. Furthermore, the trash can is made of plastic, and the thickness of the hanging ear is generally less than 20mm, while the maximum recognition distance of the proximity switch 17 can reach 50mm, so it does not affect the recognition effect of the proximity switch 17 at all. In other embodiments, the proximity switch 17 can also be a Hall effect proximity switch. This switch requires power to operate, but its advantage is that it can detect both magnets and magnetic metals, such as iron or carbon steel. When detecting magnetic metals, it is not necessary to fix a magnet on the pressure plate body 21; the pressure plate body can be made of iron or carbon steel, and the proximity switch 17 can be triggered directly by the pressure plate body itself. Of course, in other embodiments, the proximity switch 17 can also be an inductive proximity switch, which can also be used to detect metals.

[0052] In other embodiments of the garbage truck hanging bin mechanism: except for the hanging claw body with the mounting block, the other hanging claw bodies do not need to be fixed with reinforcing blocks. The hanging claw body itself constitutes the hanging claw, that is, only the hanging claw body with the mounting block is reinforced. Of course, in other embodiments, all hanging claw bodies can also constitute the hanging claw themselves, and no mounting block is set. In this case, the proximity switch is directly fixed to the hanging claw body, and the hanging claw body and the hanging plate body can be fixed separately. That is, the proximity switch is first fixed to the hanging claw body, and then the hanging claw body is fixed to the upper end of the hanging plate body. At this time, the hanging claw body has a stepped hole with a smaller upper part and a larger lower part to realize the internal installation of the proximity switch. Of course, the hanging claw body and the hanging plate body can also be connected as one piece, and the hanging claw body and the hanging plate body have sufficient thickness. The hanging claw body has a stepped hole with a smaller upper part and a larger lower part, and the hanging plate body has a groove with a certain length that communicates with the stepped hole. The groove is located below the stepped hole and can accommodate the proximity switch, so that the proximity switch is first placed in the groove and then installed from bottom to top into the stepped hole to realize the internal installation of the proximity switch.

[0053] In other embodiments of the garbage truck bin-hanging mechanism: when the mounting block is L-shaped, depending on the specific length of the horizontal section, if the proximity switch does not interfere with the vertical section, then it is not necessary to set a groove on the vertical section.

[0054] In other embodiments of the garbage truck bin-hanging mechanism: In order to ensure that the automatic control process can be started smoothly, proximity switches can be installed on the two hanging claws respectively, so as to avoid affecting the automatic operation if one of them fails. At this time, the two hanging claws on which the proximity switches are installed are based on the principle of non-interference and ease of installation and operation. They can be on the leftmost and rightmost hanging claws or on the middle two hanging claws.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
