DETAILED DESCRIPTION

[0047] For the convenience of description, a first direction, a second direction, and a third direction are set, and the first direction, the second direction, and the third direction are perpendicular to each other. However, those skilled in the art should understand that the embodiments of the present application are not limited to the situation where the three directions are perpendicular to each other.

Sometimes the direction indicated by arrow X along the first direction is called "upward", and the opposite direction is called "downward".

[0048] According to some embodiments of the present application, please refer to Figures 1 to 18The present invention provides an airport baggage weighing power generation device 100, comprising a power generation device 1, a sliding device 2 and a weighing device 3. The power generation device 1 comprises a bottom plate 11, a mounting base 12, a power generation base 13, two or more power generation components 14, a battery 15 and a supporting plate 16. The mounting base 12 is mounted on the bottom plate 11, and the power generation base 13 is mounted on the mounting base 12. The power generation base 13 has an accommodating cavity 131 inside. The power generation component 14 is installed in the accommodating cavity 131. The power generation component 14 comprises a power generation rack 141, a power generation elastic member 142, a power generation gear 143, a support plate 144 and a power generation rack. The motor 145, the power generation rack 141 is installed at the bottom of the accommodating chamber 131 through the power generation elastic member 142, the power generation rack 141 is meshed with the power generation gear 143, the power generation gear 143 is rotatably connected with the support plate 144, the support plate 144 is installed at the bottom of the accommodating chamber 131, the power generation gear 143 is transmission-connected with the input shaft 1451 of the generator, the power generation racks 141 of more than two groups of power generation components 14 are arranged in a staggered manner along the height of the first direction X, the storage battery 15 is connected to more than two power generation components 14, the support plate 16 is mounted on the mounting base 12, and the bottom of the support plate 16 is connected to at least one group of power generation components 14. The top of the power generation rack 141 is in contact; the sliding device 2 is installed on the bottom plate 11 and is located on one side of the mounting base 12. The sliding device 2 includes two sets of lifting components 21 and a sliding frame 22. The lifting component 21 includes a lifting motor 211, a connecting rod 212, two rotating rods 213, two transmission rods 214 and two slide plates 215. The lifting motor 211 is installed on the bottom plate 11. The output end of the lifting motor 211 is connected to the connecting rod 212. The two rotating rods 213 are respectively sleeved on the front end and the rear end of the connecting rod 212. Each connecting rod 212 is hinged to a transmission rod 214. The transmission rod 214 The two sets of lifting components 21 are respectively installed on both sides of the sliding frame 22 through the sliding plate 215 that is slidably connected to the bottom of the sliding frame 22. The rotation speed of the lifting motor 211 away from the power generation device 1 is higher than the rotation speed of the lifting motor 211 close to the power generation device 1, so that the sliding frame 22 is tilted toward the supporting plate 16; the weighing device 3 includes a weighing sensor, a support rod 31 and a display 32. The weighing sensor is installed at the bottom of the power generation base 13, the support rod 31 is installed at the rear end of the power generation base 13, the display 32 is installed on the support rod 31, and is communicated with the weighing sensor, and the battery 15 is connected to the display 32.

[0049] The bottom plate 11 is extended along the second direction Y, one side of the bottom plate 11 is used for mounting the mounting base 12, and the other side of the bottom plate 11 is used for mounting the sliding device 2. The structure of each group of power generation components 14 is the same, except that the power generation rack 141 is arranged at a staggered height along the first direction X, that is, the power generation elastic member 142 of each group of power generation components 14 has a difference in height along the first direction X, so that the power generation rack 141 and the bottom of the accommodating cavity 131 have a difference in height along the first direction X. It is necessary to ensure that the top of the power generation rack 141 of at least one group of power generation components 14 is in contact with the bottom of the supporting plate 16, so that lighter luggage can also generate electricity. In some embodiments, in order to strengthen the support of the power generation rack 141, the power generation component 14 also includes a power generation telescopic rod, which can be telescopic up and down along the first direction X. The power generation telescopic rod is arranged in the power generation elastic member 142, the bottom of the power generation telescopic rod is connected to the bottom of the accommodating cavity 131, and the top of the power generation telescopic rod is connected to the bottom of the power generation rack 141. Among them, two or more groups of power generation components 14 are arranged in a staggered manner, and there are multiple staggered arrangements. Figures 5 to 7 As shown, three groups of power generation components 14 are provided, and the heights of the power generation racks 141 of the three groups of power generation components 14 can be arranged in a high, medium, and low manner, or in a medium, high, and low manner, or in a medium, low, and high manner, and the arrangement manners are various. Among them, the top of the highest power generation rack 141 contacts the bottom of the supporting plate 16.

[0050] The lifting speeds of the two lifting assemblies 21 are different, that is, the speeds of the lifting motors 211 of the two lifting assemblies 21 are different, and the speed of the lifting motor 211 far from the support plate 16 is set higher than the speed of the lifting motor 211 close to the support plate 16, so that the sliding frame 22 is tilted toward the support plate 16 as a whole under the action of the two lifting assemblies 21. Figure 2 and Figure 3As shown, the side of the sliding frame 22 close to the supporting plate 16 can be set flush with the supporting plate 16, and the side of the sliding frame 22 close to the supporting plate 16 can also be set slightly higher than the supporting plate 16 to increase the potential energy of the luggage. Among them, the connecting rod 212 is extended along the third direction Z. The lifting component 21 also includes a motor mounting plate 216, which is installed at the rear end of the base plate 11, and the lifting motor 211 is installed on the motor mounting plate 216. Optionally, the lifting component 21 also includes a slider 217, a slide rail 221 is provided at the bottom of the sliding frame 22, and a slider 217 is provided on the slide plate 215, and the slider 217 is slidably connected to the slide rail 221. The cooperation between the slider 217 and the slide rail 221 makes the lifting of the sliding frame 22 more stable. In some embodiments, in addition to being controlled by the lifting motor 211, the lifting assembly 21 can also be controlled by a hydraulic lifting rod. A hydraulic lifting rod is set on each side of the sliding frame 22. The hydraulic lifting rod away from the supporting plate 16 is started first for a few seconds (such as 3S or 5S), and then the hydraulic lifting rod close to the supporting plate 16 is started synchronously, so that the sliding frame 22 can be tilted toward the supporting plate 16 as a whole.

[0051] Since the storage power of the battery 15 is limited and not stable enough, in actual use, it generally provides power for the display 32, while the power of the weighing sensor and other equipment can be connected through an external power supply.

[0052] The technical solution of the present application is provided with a special power generation device 1, which uses the gravity of the luggage to generate electricity. At the same time, the power generation quantity of the power generation component 14 can be determined according to the weight of the luggage, so that the luggage with a heavier weight can effectively convert mechanical energy into electrical energy, and the problem of only one set of power generation components 14 being easily damaged and having limited power generation efficiency can be avoided. The power of multiple sets of power generation components 14 is stored by the battery 15 to meet the power consumption required for luggage weighing, reducing dependence on external electricity, improving energy utilization efficiency, and reducing operating costs. In addition, a sliding device 2 is also provided to tilt the sliding frame 22 toward the support plate 16, so that the luggage can slide from the sliding frame 22 to the support plate 16, and obtain greater potential energy by sliding the luggage, effectively improving the power generation efficiency.

[0053] like Figures 1 to 3 As shown, the power generation device 1 further includes a baffle 19 , which is installed on the other side of the mounting base 12 . The baffle 19 is used to block the luggage so that the luggage on the sliding rack 22 can slide onto the supporting plate 16 .

[0054] The baffle 19 is provided to prevent the luggage from sliding out of the supporting plate 16 due to excessive potential energy, so that the luggage can be well landed on the supporting plate 16 for weighing. Optionally, the angle between the baffle 19 and the supporting plate 16 is set to be 30° to 90°.

[0055] like Figure 8 and Fig. 9As shown, the power generation assembly 14 also includes a first pulley 1461, a first belt 1462, a second pulley 1463, a second belt 1464 and a third pulley 1465. The first pulley 1461 and the power generation gear 143 are respectively installed on both sides of the support plate 144, and the first pulley 1461 and the power generation gear 143 rotate coaxially. The first pulley 1461 is connected to the second pulley 1463 through the first belt 1462. The second pulley 1463 is rotatably installed in the middle of the support plate 144. The second pulley 1463 is connected to the third pulley 1465 through the second belt 1464. The third pulley 1465 is installed on the input shaft 1451 of the generator.

[0056] The first pulley 1461 rotates coaxially with the power generation gear 143 via a rotating shaft, and the power generation gear 143 and the first pulley 1461 are respectively located on two sides of the support plate 144 . The power generation gear 143 is connected to the input shaft 1451 of the generator through a belt transmission. In actual use, the passenger slides the luggage onto the support plate 16 through the sliding frame 22, and the support plate 16 moves downward along the first direction X relative to the power generation base 13. The support plate 16 contacts the power generation rack 141, causing the power generation rack 141 to move downward. At the same time, the power generation elastic member 142 is compressed, and the power generation rack 141 drives the power generation gear 143 to rotate clockwise through the meshing relationship with the power generation gear 143. The power generation gear 143 then drives the coaxial first pulley 1461 to rotate, and the first pulley 1461 drives the second pulley 1463 to rotate synchronously through the first belt 1462, and the second pulley 1463 drives the third pulley 1465 to rotate synchronously through the second belt 1464, and finally the input shaft 1451 of the generator rotates to generate electricity. In some embodiments, power transmission can also be performed through transmission methods such as chain transmission or gear transmission.

[0057] like Figure 8 and Fig. 9 As shown, the diameter of the second pulley 1463 is larger than the diameter of the third pulley 1465. By setting the diameter of the second pulley 1463 to be larger than the diameter of the third pulley 1465, the third pulley 1465 rotates faster, the input shaft 1451 of the generator rotates faster, and the power generation efficiency is improved.

[0058] like Fig. 9 and Fig.10As shown, the power generation device 1 also includes a ratchet assembly 17, which includes a fixed plate 171, a ratchet 172 and a pawl 173. The fixed plate 171 is fixedly installed at the bottom of the accommodating chamber 131 and is sleeved outside the input shaft 1451 of the generator. The ratchet 172 is fixedly installed outside the input shaft 1451 of the generator and is located between the fixed plate 171 and the third pulley 1465. The pawl 173 is installed on the fixed plate 171, and the pawl 173 is used to limit the ratchet 172 from rotating counterclockwise.

[0059] After the luggage is taken out from the support plate 16, the generator rack 141 will be restored to its original state by the generator elastic member 142. In this process, the generator gear 143, the first pulley 1461, the first belt 1462, the second pulley 1463, the second belt 1464 and the third pulley 1465 will rotate counterclockwise, which may easily cause the input shaft 1451 of the generator to reverse due to inertia or reverse torque. Therefore, a ratchet assembly 17 is provided to limit the counterclockwise rotation of the third pulley 1465, that is, the third pulley 1465 can only rotate clockwise, so as to protect the generator 145. In this process, in order to ensure that the generator rack 141 can be restored to its original state, the first belt 1462 or the second belt 1464 will idle to a certain extent. Among them, the combination of the pawl 173 and the ratchet 172 is the prior art. In this embodiment, Fig.10 As shown, the pawl 173 includes a fixed seat 1731, a first limiting rod 1732, a limiting spring 1733, a second limiting rod 1734 and a limiting tooth 1735. The front end of the fixed plate 171 close to the ratchet 172 is equipped with a fixed seat 1731, the first limiting rod 1732 is installed on the fixed seat 1731, the first limiting rod 1732 is provided with a limiting spring 1733, the rear end of the first limiting rod 1732 is hinged with a limiting tooth 1735 through the second limiting rod 1734, the limiting tooth 1735 cooperates with the ratchet 172, and the limiting tooth 1735 is used to limit the counterclockwise rotation of the ratchet 172. Specifically, when the ratchet 172 rotates clockwise, the pawl 173 slides on the tooth back of the ratchet 172, and will not hinder the rotation of the ratchet 172. When the ratchet 172 tends to rotate counterclockwise, the pawl 173 will be stuck in the tooth groove of the ratchet 172 to prevent the ratchet 172 from rotating in the opposite direction, thereby limiting the ratchet 172 to rotate in only one direction.

[0060] In some embodiments, since the first belt 1462 or the second belt 1464 is prone to wear due to long-term idling, the power transmission can also be directly blocked by the clutch. Specifically, the power generation device 1 also includes a clutch and a position sensor. The clutch is mounted outside the input shaft 1451 of the generator. The clutch is connected to the position sensor for communication. The position sensor is installed at the bottom of the accommodating chamber 131. The position sensor is used to detect the position change of the support plate 16 in real time. When the position sensor detects that the support plate 16 begins to rise, the clutch is controlled to disconnect, disconnecting the transmission between the restoring force of the power generation rack 141 and the input shaft 1451 of the generator.

[0061] The clutch is used to connect or disconnect the power transmission between the power generation rack 141 and the input shaft 1451 of the generator. Specifically, in the initial position, the clutch is in a coupled state, that is, it is ensured that the generator 145 can generate electricity normally when the support plate 16 descends. Only when the position sensor detects that the support plate 16 begins to rise, the clutch is controlled to disconnect, disconnecting the transmission between the restoring force of the power generation rack 141 and the input shaft 1451 of the generator.

[0062] like Fig.11 As shown, the power generation device 1 also includes more than two groups of buffer components 18, which are installed in the accommodating cavity 131. The buffer components 18 include a spring compensator 181, a buffer telescopic rod 182 and a buffer elastic member 183. The spring compensator 181 is fixedly installed at the bottom of the accommodating cavity 131. The buffer telescopic rod 182 is installed in the spring compensator 181. The buffer elastic member 183 is sleeved outside the buffer telescopic rod 182. The bottom of the buffer elastic member 183 is connected to the spring compensator 181, and the top of the buffer elastic member 183 is connected to the bottom of the supporting plate 16.

[0063] Since the support plate 16 has a certain weight, in order to avoid the difficulty of resetting the support plate 16 by relying solely on the restoring force of the power generation elastic member 142 of the power generation rack 141, a buffer assembly 18 is provided. Among them, by providing a spring compensator 181, the elasticity and stiffness of the buffer elastic member 183 can be maintained within a predetermined range. When the buffer elastic member 183 is disturbed by the external environment or load fluctuations, it can be compensated in time and the influence of the supporting force of the buffer elastic member 183 on the weight measurement result can be eliminated. The buffer telescopic rod 182 can slide up and down along the first direction X, and the buffer telescopic rod 182 is used to strengthen the support of the support plate 16.

[0064] like Fig.13As shown, the sliding device 2 also includes two sets of guide components 23, which are respectively installed at the front end and the rear end of the sliding frame 22. The guide components 23 include a connecting plate 231, a guide sleeve 232 and a guide slide rod 233. The connecting plate 231 is connected to the sliding frame 22, the guide sleeve 232 is hinged to the connecting plate 231, the guide sleeve 232 is sleeved outside the guide slide rod 233, the guide slide rod 233 is extended along the first direction X, and the bottom of the guide slide rod 233 is installed on the bottom plate 11.

[0065] The two sets of guide assemblies 23 are provided to support and stabilize the sliding frame 22, so that the sliding frame 22 is more stable when it is inclined to rise or fall. Specifically, when the sliding frame 22 is inclined to rise, the guide sleeve 232 is hinged with the connecting plate 231, so that the guide sleeve 232 slides on the guide slide bar 233, and the overall position of the guide sleeve 232 rises.

[0066] In some embodiments, the airport baggage weighing and power generation equipment 100 also includes a camera and a pushing device 4. The camera is installed on the support rod 31, the camera is aimed at the sliding frame 22, the camera is communicated with the pushing device 4, and the camera is used to detect the position changes of the luggage on the sliding frame 22 in real time; when the camera detects that the position of the luggage on the sliding frame 22 has not changed within a specified time, the pushing device 4 is controlled to start, and the pushing device 4 pushes the luggage on the sliding frame 22 to the support plate 16.

[0067] The camera is arranged to cooperate with the pushing device 4 to prevent the inclination angle of the sliding frame 22 from being insufficient when the luggage is too light, so that the luggage cannot be slid onto the supporting plate 16. Specifically, when the camera detects that the position of the luggage on the sliding frame 22 has not changed within a specified time (for example, 3S or 5S), the pushing device 4 is controlled to start, and the pushing device 4 pushes the luggage on the sliding frame 22 onto the supporting plate 16. Among them, the pushing device 4 can be an existing pushing device 4, such as hydraulic pushing or pneumatic pushing. In some embodiments, the camera can also be connected to the lifting motor 211 in communication. When the camera detects that the position of the luggage on the sliding frame 22 has not changed within a specified time (for example, 3S or 5S), the lifting motor 211 away from the supporting plate 16 is controlled to start, so that the inclination angle of the sliding frame 22 becomes larger until the luggage can slide onto the supporting plate 16. In other embodiments, the airport baggage weighing and power generation equipment 100 also includes a controller, which is respectively communicated with the power generation device 1, the sliding device 2, the weighing device 3, the camera and the pushing device 4, and is uniformly controlled by the controller, which is more flexible and has a higher degree of automation.

[0068] like Figures 15 to 18As shown, the pushing device 4 is installed in the sliding frame 22, and the pushing device 4 includes two groups of moving components 41 and a pushing component 42. The top of the sliding frame 22 is provided with an opening 222, and the top of the sliding frame 22 is also provided with two slide grooves 223 extending to the opening 222 along the second direction Y; the two groups of moving components 41 are respectively installed at the front end and the rear end of the sliding frame 22, and the moving component 41 includes a moving motor 411, a moving screw rod 412, a moving block 413 and a moving limit rod 414, and the output end of the moving motor 411 is connected to the moving screw rod 412, and the moving screw rod 412 extends along the second direction Y. Installed on the sliding frame 22, the moving block 413 is sleeved outside the moving screw rod 412 and is threadedly connected to the moving screw rod 412, and the moving limit rod 414 passes through the moving block 413 along the second direction Y and is installed on the sliding frame 22; the pushing component 42 includes two pushing motors 421 and a pushing frame 422, the two pushing motors 421 are installed on the opposite surfaces of the two moving blocks 413, and the two pushing motors 421 are connected to the pushing frame 422; wherein the pushing motor 421 is used to drive the pushing frame 422 to protrude from the opening 222, and the moving motor 411 is used to drive the pushing frame 422 to move along the second direction Y.

[0069] Optionally, the moving assembly 41 further includes a limit frame 415 , the outer side of the moving screw rod 412 is rotatably connected to the limit frame 415 , the limit frame 415 is fixedly connected to the sliding frame 22 , and the limit frame 415 is fixed by the sliding frame 22 .

[0070] In the initial position, the opening 222 is set away from the supporting plate 16, and the pushing frame 422 is located below the opening 222. When the luggage needs to be pushed, the pushing motor 421 drives the pushing frame 422 to rotate to protrude from the opening 222, and the moving motor 411 drives the pushing frame 422 to push the luggage to the supporting plate 16 along the two slide grooves 223 to the left along the second direction Y. After the pushing motor 421 has completed the pushing, the moving motor 411 drives the pushing frame 422 to move to the right along the two slide grooves 223 along the second direction Y to the position of the opening 222, and the pushing motor 421 drives the pushing frame 422 to rotate to restore the original state.

[0071] like Fig.16 As shown, the push frame 422 is L-shaped. Compared with the general push frame 422, the L-shaped push frame 422 provides better support, which can effectively reduce shaking and improve pushing stability when pushing luggage.

[0072] The working principle of an airport luggage weighing power generation device 100 is as follows: first, the tilt angle of the sliding frame 22 is initially set. Specifically, the lifting motor 211 rotates the connecting rod 212, and the connecting rod 212 then drives the rotating rod 213 to rotate, and the rotating rod 213 then drives the transmission rod 214 to rotate, so that the slide plate 215 slides leftward or rightward along the second direction Y along the bottom of the sliding frame 22, and the sliding frame 22 rises. Among them, the speed of the lifting motor 211 far away from the support plate 16 is set to be higher than the speed of the lifting motor 211 close to the support plate 16, so that the sliding frame 22 is tilted toward the support plate 16 as a whole under the action of the two sets of lifting components 21. Secondly, the luggage slides onto the support plate 16 along the sliding frame 22. During this process, the camera will detect whether the luggage cannot slide onto the support plate 16. If it cannot slide onto the support plate 16 normally, the pushing device 4 will be started to push the luggage onto the support plate 16. If the luggage is too heavy during this process, the baffle 19 acts as a barrier, so that the luggage can fall onto the support plate 16. When the luggage has slid onto the support plate 16, the number of power generation components 14 that generate electricity is determined according to the weight of the luggage, but in any case, at least one group of power generation components 14 can generate electricity. Specifically, the support plate 16 contacts the power generation rack 141, causing the power generation rack 141 to move downward. At the same time, the power generation elastic member 142 is compressed, and the power generation rack 141 drives the power generation gear 143 to rotate clockwise through the meshing relationship with the power generation gear 143. The power generation gear 143 then drives the coaxial first pulley 1461 to rotate. The first pulley 1461 drives the second pulley 1463 to rotate synchronously through the first belt 1462. The second pulley 1463 then drives the third pulley 1465 to rotate synchronously through the second belt 1464, and finally the input shaft 1451 of the generator rotates to generate electricity, which is stored in the battery 15. Finally, the weighing sensor weighs and displays the weight data of the luggage through the display 32.
