[0033] A passenger flow meter, also known as a passenger flow analyzer, is an instrument that performs real-time statistical analysis of passenger flow within a specified area. This analysis is required in a wide range of scenarios, including scenic spots, shopping malls, and public transportation. However, conventional passenger flow meters are typically fixed, making their monitoring angle inadvisable. This results in poor installation and performance.
[0034] Based on the above considerations, in order to solve the problem that the passenger flow meter in the related technology cannot adjust the monitoring angle and thus leads to poor use effect, a passenger flow meter is designed, wherein the passenger flow meter can adjust the angle of the passenger flow meter body relative to the mounting bracket, and after the angle adjustment is completed, the locking member can be used to lock it on the connecting surface of the shell, so that the passenger flow meter body is locked relative to the mounting bracket, and then the passenger flow meter body can maintain the current angle to achieve the purpose of angle adjustment.
[0035] The passenger flow meter provided in the embodiment of the present application can be used, but is not limited to, for passenger flow counting operations in places with large passenger flow, such as public transportation, shopping malls, gymnasiums, and cinemas.
[0036] Below, the passenger flow meter of the embodiment of the present application will be described in detail.
[0037] Please refer to Figures 1 to 3 The embodiment of the present application provides a passenger flow meter 1000, including a mounting bracket 100, a passenger flow meter body 200 and a locking member 300. The mounting bracket 100 is formed with an assembly cavity 101, and a locking hole 102 is opened on the mounting bracket 100, and the locking hole 102 is connected to the assembly cavity 101; the passenger flow meter body 200 is accommodated in the assembly cavity 101; the passenger flow meter body 200 includes a shell 210 and a camera assembly 220 arranged on the shell 210, and the shell 210 has two oppositely arranged connecting surfaces 21a facing the inner wall surface of the assembly cavity 101, and the connecting surfaces 21a are rotatably connected to the mounting bracket 100 through a rotating shaft 201; the locking hole 102 faces the connecting surface 21a; the locking member 300 is passed through the locking hole 102, and the locking member 300 is used to lock on the connecting surface 21a.
[0038] Among them, the mounting bracket 100 is used to achieve fixed installation; for example, the mounting bracket 100 can be fixedly installed on the body of a vehicle, on the walls of places such as shopping malls, gymnasiums, and cinemas, etc., for example, by fasteners such as screws, bolts, and expansion screws.
[0039] The passenger flow meter body 200 is used to implement monitoring operations. The passenger flow meter body 200 is housed in the assembly cavity 101, and the housing 210 of the passenger flow meter body 200 is rotatably connected to the mounting bracket 100 via the rotating shaft 201. As a result, the passenger flow meter body 200 can rotate relative to the mounting bracket 100 within the assembly cavity 101. In other words, the passenger flow meter body 200 can adjust its angle relative to the mounting bracket 100, and the camera assembly 220 of the passenger flow meter body 200 can adjust the monitoring angle, thereby effectively improving the monitoring effect of the passenger flow meter 1000.
[0040] Among them, the connecting surface 21a is the two opposite end surfaces on the outer shell 210 of the passenger flow meter body 200, and the connecting surface 21a faces the inner wall surface of the assembly cavity 101. Therefore, the rotating shaft 201 can be connected to the connecting surface 21a, and the rotating shaft 201 is rotatably connected to the inner wall surface of the assembly cavity 101, so that the passenger flow meter body 200 can achieve synchronous rotation through the rotation of the rotating shaft 201 relative to the mounting bracket 100.
[0041] The locking member 300 is used to lock the connecting surface 21a; wherein, a locking hole 102 is opened on the mounting bracket 100, the locking hole 102 is connected to the assembly cavity 101 and faces the connecting surface 21a, thereby, the locking member 300 can be passed through the locking hole 102 and act on the outer shell 210 of the passenger flow meter body 200 to lock the connecting surface 21a of the outer shell 210, thereby locking the entire passenger flow meter body 200 and preventing it from continuing to rotate.
[0042] Optionally, the locking member 300 can be a structure with a thread, such as a bolt, a screw, etc., and the locking hole 102 can be provided with an internal thread accordingly, so that the locking member 300 can be screwed into the locking hole 102 through a thread, and the locking member 300 can be screwed into the locking hole 102 to a depth to form a tight abutment with the connecting surface 21a, thereby achieving the purpose of locking the connecting surface 21a.
[0043] Alternatively, the locking member 300 may also be a structure having a thread or an external hexagon (or a polygonal structure such as an external triangle or an external square), and the locking hole 102 may be provided with an internal thread or an internal hexagon structure, etc. At the same time, two or more locking grooves are formed on the connecting surface 21a, so that the locking member 300 can pass through the locking hole 102 and be inserted into the locking groove, and at this time the locking member 300 can lock the connecting surface 21a.
[0044] The passenger flow meter 1000 provided in the embodiment of the present application has a mounting bracket 100 for implementing the installation operation. The passenger flow meter body 200 can be accommodated in the assembly cavity 101 of the mounting bracket 100 and can be rotated through the rotating shaft 201 to adjust the angle. At the same time, the locking member 300 can be passed through the locking hole 102 of the mounting bracket 100 and locked to the connecting surface 21a of the outer shell 210 of the passenger flow meter body 200; thus, the passenger flow meter 1000 can adjust the angle of the passenger flow meter body 200 relative to the mounting bracket 100, and after completing the angle adjustment, the locking member 300 can be locked to the connecting surface 21a of the outer shell 210, so that the passenger flow meter body 200 forms a locked state relative to the mounting bracket 100, and then the passenger flow meter body 200 can maintain the current angle to achieve the purpose of angle adjustment.
[0045] Please refer to Figures 1 to 3 In some embodiments, an adjustment hole 202 is formed at the end of the rotating shaft 201 in the axial direction, and a through hole 103 is formed on the mounting bracket 100 , and the adjustment hole 202 is exposed to the mounting bracket 100 through the through hole 103 .
[0046] The adjustment hole 202 is used for inserting an external structure to achieve rotational adjustment of the rotating shaft 201 , thereby achieving angle adjustment of the housing 210 and the passenger flow meter body 200 .
[0047] Optionally, the adjustment hole 202 can be, but is not limited to, a polygonal hole such as a triangular screw hole, a square screw hole, a hexagonal screw hole, or can also be a straight slot, a cross slot, etc.; thus, the external structure can use a corresponding adjustment plate to achieve rotation adjustment of the rotating shaft 201 from the outside.
[0048] A through hole 103 is provided on the mounting bracket 100 ; optionally, the through hole 103 may only allow the adjustment hole 202 to be exposed; or, the through hole 103 may allow the entire shaft 201 to be exposed, that is, the shaft 201 is rotatably inserted into the through hole 103 .
[0049] The mounting bracket 100 may have only one through hole 103 oriented toward one of the rotating shafts 201 ; or, the mounting bracket 100 may have two through holes 103 oriented toward the rotating shafts 201 at both ends, so that the angles of the two rotating shafts 201 can be adjusted.
[0050] Please refer to Figures 1 to 3 In some embodiments, the adjustment hole 202 is a hexagonal screw hole.
[0051] In this embodiment, the adjustment hole 202 can be a hexagonal screw hole; therefore, the external structure can be a hexagonal sheet metal handle, such as an L-shaped hexagonal sheet metal handle.
[0052] By inserting a hexagonal wrench into the hexagonal screw hole and then twisting the hexagonal wrench, the rotating shaft 201 is rotated synchronously, and then the passenger flow meter body 200 can be rotated synchronously and the angle adjustment can be achieved.
[0053] Please refer to Figures 1 to 3 In some embodiments, the housing 210 includes a front shell 211 and a back cover 212, the front shell 211 and the back cover 212 are covered and connected, and a lens 213 and a filter 214 are provided on the front shell 211; the camera assembly 220 is arranged in the front shell 211 and the back cover 212, and the camera end of the camera assembly 220 faces the lens 213.
[0054] It is understood that the front shell 211 and the rear cover 212 are connected and overlapped to form a housing space for accommodating the camera assembly 220. The front shell 211 and the rear cover 212 can be fixedly connected by fasteners; the connecting surface 21a can be a portion of the end surface of the front shell 211; or the connecting surface 21a can be a portion of the end surface of the rear cover 212; or the connecting surface 21a can be formed by combining a portion of the end surface of the front shell 211 and a portion of the end surface of the rear cover 212.
[0055] The front shell 211 is provided with a lens 213 and a filter 214 , wherein the lens 213 is used for the camera assembly 220 to shoot outside the front shell 211 , and the filter 214 is used for filtering external light before it enters the front shell 211 .
[0056] The camera assembly 220 is used to perform a shooting operation, thereby enabling the purpose of monitoring the flow of people being filmed. The camera assembly 220 can be fixed between the front housing 211 and the rear cover 212 using fasteners such as screws, with the camera end of the camera assembly 220 facing the lens 213. As a result, the camera can shoot outside the front housing 211 through the lens 213 to achieve the purpose of monitoring.
[0057] Please refer to Figures 1 to 3 In some embodiments, the passenger flow meter body 200 further includes a circuit board 215 disposed between the front shell 211 and the back cover 212 , the circuit board 215 being electrically connected to a photosensor 216 and a fill light 217 , and the circuit board 215 being electrically connected to a camera assembly 220 .
[0058] The circuit board 215 is used to electrically control the camera assembly 220 ; the circuit board 215 can be fixedly installed between the front shell 211 and the back cover 212 by fasteners such as screws.
[0059] The circuit board 215 is electrically connected to a light sensor 216 and a fill light 217. The light sensor 216 is used to sense light intensity, and the fill light 217 is used to provide fill light for the camera assembly 220. Thus, the light sensor 216 can be used to sense ambient light intensity. When the ambient light intensity is lower than a preset value, the fill light 217 can be turned on to provide fill light, thereby improving the monitoring effect of the camera assembly 220.
[0060] Please refer to Figures 1 to 3 In some embodiments, the housing 210 further includes a sealing ring 218 , which is sandwiched between the front shell 211 and the back cover 212 .
[0061] Optionally, the sealing ring 218 includes but is not limited to a rubber sealing ring, a silicone sealing ring, etc.; when the front shell 211 and the back cover 212 are covered and connected, the sealing ring 218 can be clamped in the part where the front shell 211 and the back cover 212 are in contact, and the sealing ring 218 can fill the gap between the part where the front shell 211 and the back cover 212 are in contact, thereby improving the sealing performance inside the front shell 211 and the back cover 212.
[0062] With such an arrangement, the sealing performance of the passenger flow meter 1000 can be effectively improved.
[0063] Please refer to Figure 2 and Figure 4 In some embodiments, the mounting bracket 100 has a mounting end 110 and an assembly end 120 intersecting the mounting end 110 , and a connecting hole 111 is provided on the mounting end 110 ; a monitoring port 121 is provided on the assembly end 120 , and the assembly cavity 101 is connected to the outside through the monitoring port 121 .
[0064] The mounting end 110 is used to achieve fixed installation. For example, a fastener (such as a screw, etc.) can be inserted into the connection hole 111, and the mounting end 110 can be fixedly installed in a vehicle, a cinema, or a shopping mall.
[0065] The assembly end 120 is provided with a monitoring port 121 , whereby when the passenger flow meter body 200 is rotated and disposed in the assembly cavity 101 , the passenger flow meter body 200 can be exposed through the monitoring port 121 , so that the camera assembly 220 in the passenger flow meter body 200 can monitor outward through the monitoring port 121 .
[0066] It can be understood that the mounting end 110 and the assembly end 120 are arranged to intersect, that is, the surface where the mounting end 110 is located intersects with the surface where the assembly end 120 is located; thereby, the mounting bracket 100 can achieve a side-mounted effect, that is, the mounting end 110 can be installed on the vertical face of the vehicle, so that the monitoring port 121 can face downward, for example, toward the lower door, so as to monitor the flow of people.
[0067] Please refer to Figures 1 to 3 In some embodiments, the mounting bracket 100 has a mounting end 110, which is provided with a connecting hole 111; a connecting protrusion 130 is provided on the mounting end 110, and a monitoring port 121 is provided on the side of the connecting protrusion 130 facing away from the mounting end 110, and the assembly cavity 101 is connected to the outside through the monitoring port 121; a locking hole 102 is provided on the connecting protrusion 130, and the housing 210 is rotatably connected to the connecting protrusion 130 via a rotating shaft 201.
[0068] In this embodiment, the mounting end 110 can be fixedly installed through the connecting hole 111. At the same time, the monitoring port 121 is opened on the connecting protrusion 130 provided on the mounting end 110; thus, the passenger flow meter body 200 can be connected to the connecting protrusion 130 through the rotating shaft 201, and the monitoring operation is realized through the monitoring port 121 opened on the connecting protrusion 130.
[0069] A monitoring port 121 is provided on the side of the connecting protrusion 130 facing away from the mounting end 110, so that the mounting end 110 can be installed on the top, such as the top area of the vehicle, so that the monitoring port 121 can face downward, such as towards the lower door, to monitor the flow of people.
[0070] Please refer to Figure 2 and Figure 5 In some embodiments, the mounting bracket 100 includes a mounting plate and a mounting portion (not shown in the figure) arranged on one side of the mounting plate 140, and the mounting portion and the mounting plate 140 are combined to form an assembly cavity 101; a monitoring port 121 and a connecting hole 111 are provided on the mounting plate 140, and the assembly cavity 101 is connected to the outside through the monitoring port 121; a locking hole 102 is provided on the mounting portion, and the housing 210 is rotatably connected to the mounting portion through a rotating shaft 201.
[0071] In this embodiment, the mounting plate 140 can be fixedly installed through the connecting hole 111; at the same time, the monitoring port 121 is opened on the mounting plate 140, so that the passenger flow meter body 200 can be connected to the mounting part through the rotating shaft 201, and the monitoring operation is realized through the monitoring port 121 opened on the mounting plate 140.
[0072] Thus, the mounting plate 140 can be embedded, and the mounting plate 140 is embedded on the wall through the connecting hole 111 so that the mounting portion and the passenger flow meter body 200 inside are located inside.
[0073] Please refer to Figures 1 to 3 In some embodiments, the locking member 300 is a machine screw.
[0074] A set screw, also known as a set screw, comprises a threaded section and a tip structure disposed at the end of the threaded section.
[0075] It should be understood that the lock hole 102 is provided with an internal thread for the machine screw. By screwing the machine screw into the lock hole 102 and further screwing it into the connecting surface 21a, the tip structure of the machine screw abuts against the connecting surface 21a, thereby locking the connecting surface 21a.
[0076] Among them, the external sheet metal structure can be used to perform knob operation on the machine screw to lock the connecting surface 21a and the entire passenger flow meter body 200, so that the passenger flow meter body 200 can maintain the current angle.
[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
