Description

Technical Field

[0001] This application belongs to the field of photoelectric switch technology, specifically relating to a separate photoelectric switch and a photoelectric sensing control device. Background Technology

[0002] Currently, traditional split-type photoelectric switches have a separate housing structure, consisting of a base and a cover. During installation, core components such as the control board are first placed in pre-set mounting slots on the base, using the base's structure for initial positioning. Then, the cover is placed on top, and the two are secured together using screws or clips to complete assembly. However, the separate structure of the base and cover means that two independent components need to be precision-machined separately, increasing manufacturing steps and costs. Furthermore, ensuring precise alignment during assembly requires extremely high machining accuracy. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] An embodiment of the first aspect of this application provides a separate photoelectric switch; an embodiment of the second aspect of this application provides a photoelectric sensing control device.

[0028] Among them, the split photoelectric switch is used in photoelectric sensing control equipment, which can be ATMs, vending machines, etc.

[0029] Specifically, in practical applications, the information detected by the discrete photoelectric switch (such as the presence or absence of an object, its position, etc.) serves as the basis for the photoelectric sensing control device to perform corresponding actions or make decisions. The photoelectric signal is converted into an electrical signal and transmitted to other parts of the photoelectric sensing control device (such as a server), thereby realizing the control and monitoring of the operation of the photoelectric sensing control device.

[0030] join Figure 1 and Figure 2 As shown, the detachable photoelectric switch provided in the first aspect of this application includes at least two functional terminals; each functional terminal includes a housing 1, one side of which is an open structure for inserting a control motherboard. A locking member 2 is provided on one side of the control motherboard, and a stop member 3 is provided on the other side. The locking member 2 is connected to the housing 1 and is used to apply a force to the control motherboard in the direction of the stop member 3. The stop member 3 is located inside the housing 1 and is used to cooperate with the locking member 2 to clamp the control motherboard.

[0031] In this embodiment, by setting one side of the functional end housing 1 to be an open structure, the control motherboard can be directly inserted from the open side of the functional end housing 1, avoiding the need to split the housing 1 into two parts, the base and the cover, for separate processing, reducing manufacturing steps and thus reducing production costs.

[0032] Among them, the split photoelectric switch is a sensor that uses the photoelectric effect to detect the position or state of an object. It includes a transmitter and a receiver. The transmitter is responsible for emitting light outward, while the receiver is used to receive light reflected or directly transmitted by the object, thereby realizing the detection of the object's position or state.

[0033] Specifically, both the transmitter and receiver are functional terminals of a separate photoelectric switch. In practical applications, one transmitter and one receiver together constitute a set of functional terminals. It should be noted that, given the diversity and complexity of different detection tasks, multiple sets of functional terminals can be flexibly configured to fully meet detection requirements.

[0034] In this embodiment, both the transmitter and receiver housings 1 have an open-side structure, allowing the corresponding control motherboards to be easily inserted. In practical applications, the transmitter's control motherboard is a light emission driver board, which can be easily inserted through the open side of the transmitter housing 1, thus enabling rapid assembly of the transmitter. Similarly, the receiver's control motherboard is a light receiving processing board, which can also be easily inserted through the open side of the receiver housing 1, enabling rapid assembly of the receiver.

[0035] Specifically, the outer shell 1 of both the transmitter and receiver is elongated. In practical applications, the optical transmission driver board adapted to the transmitter and the optical reception processing board adapted to the receiver can be smoothly and accurately inserted into the internal space of the outer shell 1 along its length.

[0036] To ensure the stable placement of the optical transmitter driver board within the transmitter housing 1 and the stable installation of the optical receiver processing board within the receiver housing 1, locking elements 2 and stop elements 3 are installed on the transmitter and receiver housings 1, respectively. When the optical transmitter driver board is inserted through the open side of the transmitter housing 1, and the optical receiver processing board is inserted through the open side of the receiver housing 1, the locking elements 2 and stop elements 3 work together. The locking elements 2 apply a force towards the stop elements 3 to the optical transmitter driver board and the optical receiver processing board, while the stop elements 3 act as a barrier. Together, they tightly clamp the optical transmitter driver board and the optical receiver processing board. This effectively prevents the optical transmitter driver board and the optical receiver processing board from loosening or shifting due to equipment vibration, external impacts, or other factors during actual use, ensuring that the separate photoelectric switch maintains a stable and reliable operating state.

[0037] Specifically, when the light emitting driver board is inserted through the open side of the emitting end housing 1 and the light receiving processing board is inserted through the open side of the receiving end housing 1, both control boards (i.e., the light emitting driver board and the light receiving processing board) are positioned between the locking member 2 and the stop member 3. At this time, since the locking member 2 is connected to the housing 1, controlling the locking member 2 can apply a force towards the stop member 3 to the light emitting driver board and the light receiving processing board. Under this force, the control boards will move towards the stop member 3. The stop member 3, installed inside the housing 1, prevents the control boards from moving further. Through the pushing of the locking member 2 and the blocking of the stop member 3, the two work together to form a clamping force, firmly fixing the light emitting driver board and the light receiving processing board. This ensures that the light emitting driver board is stably installed inside the emitting end housing 1 and the light receiving processing board is stably installed inside the receiving end housing 1, effectively preventing the light emitting driver board and the light receiving processing board from loosening or shifting due to equipment vibration, external collisions, or other factors, ensuring the stable and reliable operation of the separate photoelectric switch.

[0038] Furthermore, in some specific examples, the locking element 2 is a spring clip mounted on the housing 1. When the control board is inserted, the elastic arm of the spring clip is compressed. When the control board is in place, the elastic arm springs back and locks onto the surface of the control board, and the spring force pushes the control board tightly against the stop element 3. In other specific examples, the locking element 2 is an eccentric wheel mounted on the housing 1. The eccentric wheel is connected to the housing 1 via a rotating shaft and can rotate around the shaft. When the control board is inserted, the eccentric wheel is rotated, causing the protruding part of the eccentric wheel to gradually approach and squeeze the control board, pushing it towards the stop element 3 and clamping it.

[0039] In addition, locking element 2 can also be configured in the following ways:

[0040] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the outer casing 1 includes a first casing wall 11 parallel to the control motherboard, and a locking member 2 is disposed perpendicular to the first casing wall 11 and threadedly connected to the first casing wall 11.

[0041] In this embodiment, the locking member 2 can be a stud or other threaded connector that is threadedly connected to the housing 1. When the stud or other threaded connector is disposed perpendicular to the first housing wall 11 of the housing 1 and is threadedly connected to the first housing wall 11, a force toward the stop member 3 can be applied to the control board inserted into the housing 1 by rotating the stud or other threaded connector, pushing it toward the stop member 3 and clamping it.

[0042] The first housing wall 11 has a threaded hole penetrating the first housing wall 11. The wall of the threaded hole has an internal thread, and the outer surface of the stud or other threaded connector has an external thread that matches the internal thread. When the control motherboard is inserted into the housing 1, the operator can rotate the stud or other threaded connector using a screwdriver or similar tool. As the stud or other threaded connector rotates, due to the meshing of the external and internal threads, the stud or other threaded connector will displace in a direction perpendicular to the first housing wall 11.

[0043] Specifically, the surface of the control main board is parallel to the first housing wall 11, and the displacement direction of the stud or other threaded connector is perpendicular to the surface of the control main board. As the stud or other threaded connector continues to rotate and approach the control main board, the front end face of the stud or other threaded connector will gradually contact and adhere to the control main board. Since the stud or other threaded connector is tightly connected to the first housing wall 11 by threads, the rotational displacement of the stud or other threaded connector is converted into a stable and continuous thrust on the control main board.

[0044] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the outer shell 1 also includes a second shell wall 12, which is located on the opposite side of the first shell wall 11, and the stop member 3 is fixedly disposed on the side of the second shell wall 12 relative to the first shell wall 11.

[0045] In this embodiment, the stop member 3 is fixedly disposed on the inner wall of the second housing 12. When the locking member 2 applies a force toward the stop member 3 to the control motherboard, the stop member 3 can effectively prevent the control motherboard from continuing to move. The two cooperate to form a clamping force, which firmly fixes the control motherboard, thereby preventing the control motherboard from loosening or shifting due to factors such as equipment vibration or external collision, and ensuring the stable and reliable operation of the split photoelectric switch.

[0046] The outer shell 1 is roughly rectangular. Within the outer shell 1, the first shell wall 11 and the second shell wall 12 are arranged opposite to each other, together forming the two opposite boundaries of the outer shell 1.

[0047] Specifically, the first housing wall 11, the second housing wall 12, and the control main board are parallel to each other. The locking elements 2 on the first housing wall 11, such as studs, spring clips, or eccentric wheels, ensure even force distribution on the control main board as it moves towards the stop element 3 due to the uniform force characteristics imparted by the parallel structure, preventing tilting or uneven force distribution. The stop element 3, located on the inner wall of the second housing wall 12, parallel to the first housing wall 11 and the control main board, can evenly and comprehensively absorb pressure from the control main board, thus tightly engaging with the locking elements 2 to form a uniform and stable clamping force.

[0048] In some possible embodiments disclosed in this application, the stop 3 is an elastic structure.

[0049] In this embodiment, by setting the stop 3 as an elastic structure, the impact force received by the control motherboard during the process of being pushed towards the stop 3 can be buffered, avoiding damage to the control motherboard due to rigid collision and protecting the integrity and performance of the control motherboard. At the same time, the elastic stop 3 will deform under force, which can better fit the surface of the control motherboard, making the clamping force distribution more uniform and improving the stability and reliability of the control motherboard installation.

[0050] The stop component 3 can be a rubber pad, elastic sheet, silicone block, etc. It should be noted that during actual use, the control board may experience slight displacement due to factors such as equipment vibration and temperature changes. The elastic stop component 3 can accommodate these slight displacements, maintaining a constant clamping force on the control board to prevent loosening or displacement, thus ensuring the stable and reliable operation of the separate photoelectric switch.

[0051] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the stop 3 extends along the width direction of the control main board.

[0052] In this embodiment, by providing a stop member 3 extending along the width direction of the control motherboard, the gap between the control motherboard surface and the inner wall of the second shell 12 can be filled. Thus, a relatively enclosed light-emitting cavity is formed inside the outer shell 1 of the transmitting end, and a relatively enclosed light-receiving cavity is formed inside the outer shell 1 of the receiving end. It should be noted that, for the transmitting end, the relatively enclosed light-emitting cavity allows for more concentrated and efficient emission of light, enhancing the intensity and directionality of the emitted light; for the receiving end, the relatively enclosed light-receiving cavity reduces interference from ambient light, improving the accuracy and stability of the detection results.

[0053] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, multiple stop members 3 are provided, and the multiple stop members 3 are arranged at equal intervals along the length direction of the outer shell 1.

[0054] In this embodiment, multiple stop members 3 are arranged at equal intervals along the length of the housing 1, ensuring that the control motherboard is subjected to clamping forces from the stop members 3 and locking members 2 at multiple positions along the length. This more evenly fixes the control motherboard, preventing displacement or shaking within the housing 1 along the length, effectively improving the stability and reliability of the control motherboard installation and ensuring the stable and reliable operation of the split photoelectric switch. Simultaneously, the equally spaced stop members 3, in conjunction with the locking members 2, form a uniform and stable clamping force across the entire length of the housing 1. This better disperses and resists external forces caused by equipment vibration, external collisions, etc., thereby enhancing the overall reliability of the split photoelectric switch structure and reducing the probability of malfunctions due to loosening or displacement of the control motherboard.

[0055] Specifically, in this embodiment, two stop members 3 are provided along the length direction of the outer shell 1.

[0056] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, at least two locking elements 2 are provided, and the at least two locking elements 2 are distributed at intervals along the length direction of the outer shell 1.

[0057] In this embodiment, multiple spaced locking elements 2 can apply force to the control motherboard at different positions, making it more securely fixed within the housing 1. This reduces potential shaking or displacement caused by the fixing of a single locking element 2, ensuring its precise position within the housing 1. Simultaneously, when one locking element 2 fails or experiences excessive pressure, the other locking elements 2 can still provide some fixing effect, providing redundant protection. This increases the reliability and fault tolerance of the entire structure, reducing the risk of the entire device malfunctioning due to the failure of a single locking element 2.

[0058] Specifically, in this embodiment, two locking members 2 are also provided along the length direction of the outer shell 1.

[0059] In some possible implementations disclosed in this application, the functional terminal also includes a connector, one end of which is connected to the control motherboard, and the other end passes through the open side of the housing 1 and is connected to an external circuit.

[0060] In this embodiment, the open side of the housing 1 serves a dual purpose. Firstly, the open side of the housing 1 provides a convenient pathway for the insertion of the control motherboard, allowing it to be directly inserted into the housing 1 from the open side. This avoids the need to separate the housing 1 into a base and a cover for separate processing, significantly reducing manufacturing steps and production costs. Secondly, the open side of the housing 1 also serves as a connector, enabling electrical connection between the internal and external circuits of the device, ensuring stable signal transmission. It also lays the foundation for the expansion, upgrading, and improved versatility and compatibility of the separate photoelectric switch. Furthermore, it facilitates the assembly and maintenance of the separate photoelectric switch, enhancing its overall performance and practicality.

[0061] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
