[0043] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0044] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0045] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0047] When the wireless transmitter is mounted on an electronic endoscope, it can transmit the image data collected by the camera module of the electronic endoscope in real time. That is, after the wireless transmitter establishes a wireless connection with the imaging device, the image data is transmitted to the imaging device, which can solve the inconvenience caused by the wired connection between the endoscope and the imaging device. Due to the size limitations of the electronic endoscope itself and the handheld use of the electronic endoscope, the wireless transmitter is required to have the characteristics of compact structure, small size, and light weight in order to be easy to use; furthermore, due to the small size of the wireless transmitter, the heat generated during operation is easy to accumulate, and the wireless transmitter is easy to be damaged. Therefore, the wireless transmitter also needs to be easy to disassemble and maintain.

[0048] In order to conveniently use the wireless transmitter on the electronic endoscope, the wireless transmitter of the present invention adopts a pin-in connection method and combines with a mounting base to connect various circuit boards. The structure is compact, the volume of the wireless transmitter is effectively reduced, and maintenance is convenient. The connector is connected to the connector base of the electronic endoscope through a connector adapter, and a signal conductor is arranged in the connector. The image data captured by the electronic endoscope is transmitted to the circuit board through the signal conductor, so that the wireless transmitter and the electronic endoscope are highly integrated, and the disassembly and assembly are simple and easy to use.

[0049] like Figure 1 As shown, the wireless transmitter of this embodiment includes two parts: a main body 10 and a connector 20. A disassembly connector is installed inside the first end 21 of the connector 20. The disassembly connector is used to detachably install the connector 20 on the electronic endoscope. The specific structure of the disassembly connector depends on the structure of the connector seat of the electronic endoscope. It can be a clamping device, a rotating device, a magnetic device, etc. The disassembly connector of this embodiment is a clamping ring, and the connector seat of the electronic endoscope has a groove. The clamping ring and the groove cooperate to achieve clamping. Specifically, as Figure 2As shown, the connector 20 is provided with a connector button 22, which is connected to a snap ring. When the connector button 22 is pressed, the snap ring is opened, and the connector 20 is sleeved on the connector seat of the electronic endoscope. When the connector button is released, the snap ring is closed and snapped into the groove, so that the connector 20 is assembled on the electronic endoscope. The second end 23 of the connector 20 is opposite to the first end 21 and is used to fix the main body 10.

[0050] In order to transmit image data from the electronic endoscope to the wireless transmitter and realize high integration of the wireless transmitter and the electronic endoscope, a signal conductor 24 is provided on the connector 20, and the signal conductor 24 runs from the first end 21 of the connector 20 to the second end 23 of the connector 20. Specifically, the signal conductor 24 includes a signal conductor seat 241 and a signal connection board 242. The signal conductor seat 241 is connected to the connector seat of the electronic endoscope through a PIN needle. The signal connection board 242 is connected to the signal conductor seat 241 and faces the body 10. Two first row pin connectors 25 are arranged at intervals on the signal connection board 242. The first row pin connectors 25 are row pins.

[0051] In order to make the main body 10 more universal and not be affected by the specific structure of the connector seat of the electronic endoscope, the present embodiment sets a transfer cover 30 between the main body 10 and the connector 20. Figure 3 As shown, a fixing column 31 is provided on one side of the adapter cover 30, and the body 10 can be fixed on the adapter cover 30 by fasteners; the other side of the adapter cover 30 is sleeved on the connector 20, and the adapter cover 30 is fixed on the connector 20 by fasteners, so that the body 10 is fixed on the connector 20 through the adapter cover 30. The adapter cover 30 is also provided with a clearance hole 32, and at least the signal connection board 242 in the signal conducting member 24 passes through the clearance hole 32 and is exposed.

[0052] The main body 10 is used to transmit the transmitted image data wirelessly. The main body 10 mainly includes a shell 11 and a mounting base 12. Figure 4As shown, the housing 11 is a rectangular column-shaped cover, with a buckle 111 provided at the bottom, a buckle groove 33 provided on the adapter cover 30, and the housing 11 is buckled on the adapter cover 30. In some examples, when the adapter cover 30 is not provided, the housing 11 is directly buckled on the connector 20. The mounting seat 12 is used to install the circuit board required for wireless transmission. In this embodiment, the mounting seat 12 is located in the housing 11 and is fixed on the adapter cover 30 by fasteners. In some examples, when the adapter cover 30 is not provided, the mounting seat 12 is directly fixed on the connector 20. A switch button 112 and a first light guide column 113 are provided on the front of the housing 11, and a support bar 114 is provided on the inner wall of the housing 11. The support part of the switch button 112 is buckled and fixed on the support bar 114, and the pressing part of the switch button 112 extends out of the housing 11 through the opening on the housing 11. The first light guide 113 is used to indicate the working state of the wireless transmitter, and the back is provided with a second light guide 115 and a charging interface 116, and the second light guide 115 is used to indicate the charging state. The charging interface 116 can be a wired charging interface of this embodiment, or a wireless charging interface.

[0053] like Figure 5 As shown, in this embodiment, the circuit boards installed on the mounting base 12 include a wireless module circuit board 13, a first circuit board 14, and a second circuit board 15. Among them, the wireless module circuit board 13 is a WI FI routing module board, such as a circuit board integrating a 2.4G Wi F i transceiver module, but is not limited to the Wi F i transceiver module of this embodiment. The wireless module circuit board 13 can also be a circuit board integrating other modules that can realize wireless transmission functions; the first circuit board 14 is used to realize control operations and function indications. Specifically, a button 141 is provided on the first circuit board 14, and the button 141 corresponds to the switch button 112 on the shell 11 to realize the switch of the wireless transmitter. The first circuit board 14 is also provided with an indicator LED light 142, and the indicator LED light 142 passes through the first light guide column 11 on the shell 11 to the outside of the shell 11 to indicate the working status of the wireless transmitter; as shown Figure 6 As shown, the second circuit board 15 is an interface board, and two female connectors are spaced apart at one end to form a second row of pin connectors 151 that cooperate with the two first row of pin connectors 25 on the signal connection board 242. After the first row of pin connectors 25 are connected with the second row of pin connectors 151, the second circuit board 15 establishes a signal connection with the signal conductor 24 to transmit image data.

[0054] refer to Figure 5In this embodiment, the pins of the second circuit board 15 are plugged into the signal conductor 24, and the pins are plugged between the wireless module circuit board 13 and the first circuit board 14, and between the first circuit board 14 and the second circuit board 15. Specifically, a female pin is provided on the first circuit board 14, and the pins on the wireless module circuit board 13 and the second circuit board 15 are plugged into the female pin of the first circuit board 14. The wireless module circuit board 13 is located between the first circuit board 14 and the second circuit board 15. After the pins are plugged in, a box-shaped structure is formed, which has a compact structure, a small size, and is easy to disassemble and maintain. In the existing wireless transmitters, the circuit boards are directly connected by lines or the boards are directly welded. The former will cause complicated winding and occupy internal space, and the latter will increase the complexity of maintenance. By using pins for plugging, there are no extra wires to occupy the internal space, while the characteristics of easy disassembly and maintenance are retained, and the internal parts are highly integrated.

[0055] like Figure 7As shown, the mounting seat 12 of this embodiment is similar to two seats with backrests connected together, with a partition 121 in the middle, and a first baffle 122 and a second baffle 123 are respectively provided at both ends of the partition 121. The two first baffles 122 and the partition 121 together form a first mounting portion 124, and the two second baffles 123 and the partition 121 together form a second mounting portion 125, and the first mounting portion 124 and the second mounting portion 125 are arranged opposite to each other. The first mounting portion 124 is used to accommodate the wireless module circuit board 13, the first circuit board 14 and the second circuit board 15. Two first through holes 126 corresponding to the second row of pin connectors 151 are provided on the bottom wall of the mounting seat 12, and two first protrusions 1221 are provided at the bottom end of the first baffle 122, and a first positioning groove 1222 is formed between the two first protrusions 1221. When the second circuit board 15 is installed, an insulating gasket (such as a Mylar sheet) is attached to the side of the second circuit board 15 facing the wireless module circuit board 13, and the second circuit board 15 is close to the partition 121, one end of which is embedded in the first positioning groove 1222, and the second row of pin connectors 151 on the second circuit board 15 passes through the first through hole 126 and is plugged into the first row of pin connectors 25. After the second circuit board 15 is installed, the wireless module circuit board 13 and the first circuit board 14 are first plugged together. Of course, the wireless module circuit board 13 and the second circuit board 15 can also be plugged together, and then the first circuit board 14 and the second circuit board 15 are plugged together. The end of the first baffle 122 away from the partition 121 is provided with four first fixing holes 1223, and the first circuit board 14 is provided with four second fixing holes 143. Through the first fixing holes 1223 and the second fixing holes 143, and by fasteners, the first circuit board 14 is threadedly fixed to the mounting seat 12. Of course, other connection methods can also be used for fixing, such as plug-in, clamping, etc. Thus, the wireless module circuit board 13, the first circuit board 14 and the second circuit board 15 are fixedly mounted on the mounting base 12. The second mounting portion 125 is used to accommodate the battery 16, and the top of the battery 16 is connected to the second circuit board 15 through wiring. The mounting base 12 is also provided with a positioning hole 127, and the adapter cover 30 is provided with a positioning pin 34 that matches the positioning hole 127. The mounting base 12 and the adapter cover 30 can be fixedly connected by screws.

[0056] For ease of use, the battery 16 in this embodiment is a rechargeable battery. Figure 8 As shown, the third circuit board 17 is provided with a charging interface 171 for charging the battery 16. Specifically, in order to reduce the volume of the wireless transmitter, the third circuit board 17 is arranged horizontally and fixed to the bottom end of the mounting base 12 by fasteners, that is, the third circuit board 17 is arranged to intersect with the second circuit board 15. Fig. 9As shown, the third circuit board 17 is provided with a first flexible connector 172, and the second circuit board 15 is provided with a second flexible connector 152. The flexible connector in this embodiment is an FPC connector. The electrical connection between the third circuit board 17 and the second circuit board 15 is achieved by inserting the two ends of the flat cable 19 into the first flexible connector 172 and the second flexible connector 152 respectively. The flat cable 19 has good flexibility and can be bent at an angle greater than 90°, which is convenient for installation and removal. Correspondingly, the bottom wall of the mounting seat 12 is also provided with a second through hole 128 for the second flexible connector 152 on the second circuit board 15 or the flat cable 19 to pass through. The lower surface of the third circuit board 17 faces the transfer cover 30. In order to meet safety requirements and enhance insulation performance, a gasket groove 35 is provided on the transfer cover 30. The gasket groove 35 corresponds to the position of the third circuit board 17. An insulating gasket is installed in the gasket groove 35. The insulating gasket can be a thin sheet cut from a Mylar sheet.

[0057] In this embodiment, two sides of the mounting base 12 are provided with card slots, and the antenna 18 is snap-fitted to the card slots on both sides of the mounting base 12 and is electrically connected to the second circuit board 15 .

[0058] In order to better realize the installation and fixation of the shell 11, a second positioning groove 1225 is set at the top of the first baffle 122, and the inner wall of the shell 11 is provided with a protrusion that cooperates with the second positioning groove 1225. When the shell 11 is installed, the shell 11 is not only buckled on the adapter cover 30, but also clamped in the second positioning groove 1225, so that the wireless transmitter is more stable.

[0059] The demand for higher pixels and lower elongation in endoscope wireless image transmission is becoming more and more urgent, but higher pixels and lower elongation will be accompanied by higher heat generation of the chip. Maintaining high heat generation for a long time will affect the stability of image transmission, and the wireless transmitter is prone to failure. Traditional heat dissipation solutions mainly include heat dissipation holes, metal fin heat dissipation, cooling fans, water cooling, etc., and the wireless transmitter is installed on the endoscope. The above traditional solutions have poor heat dissipation effects or increase the size and weight of the wireless transmitter, increasing the inconvenience and fatigue of doctors. Therefore, when considering the heat dissipation of the wireless transmitter, it is necessary to have a simple structure, less impact on the product size and weight, and at the same time have a good heat dissipation effect.

[0060] The housing 11 in this embodiment is a metal housing, and a first heat spreader 117 is installed on the inner wall of the housing 11. By way of example, a heat spreader coating may also be provided on the inner wall of the housing 11. The first heat spreader 117 is preferably a graphene heat spreader, because graphene has excellent thermal conductivity, is thin and light, and can be bent like paper, so it can be snugly arranged on the inner wall of the housing 11. When heat is conducted to a certain place on the graphene heat spreader, the heat will diffuse evenly around, causing the entire housing 11 to heat up, thereby enhancing the heat dissipation effect.

[0061] In order to dissipate the heat generated by the wireless module circuit board 13 more quickly, Fig.10 As shown, a second heat spreader 131 is wrapped on the wireless module circuit board 13, and the second heat spreader 131 at least partially extends outward until it abuts against the inner wall of the housing 11. For example, a graphene heat spreader is attached to the wireless module circuit board 13, and the top of the graphene heat spreader is attached to the inner wall of the top of the housing 11 to accelerate heat dissipation.

[0062] This embodiment also provides a foam spacer 153 between the portion where the second heat spreader 131 abuts against the inner wall of the shell 11 and the second circuit board 15. Specifically, the top of the second heat spreader 131 abuts against the inner wall of the top of the shell 11, and EVA foam is installed on the top of the second circuit board 15. The second heat spreader 131 is squeezed by the EVA foam so that the second heat spreader 131 can fit the curved surface of the shell 11. That is, heat can be quickly conducted to the top of the shell 11 through the bent and shaped graphene heat spreader and EVA foam. Furthermore, thermal grease is provided between the portion of the second heat spreader 131 abutting against the inner wall of the shell 11 and the first heat spreader 117 or the heat spreader coating on the inner wall of the shell 11. That is, the second heat spreader 131 is adhered to the housing 11 with the first heat spreader 117 by deformation of the EVA foam, and thermal conductive silicone grease is provided between the two heat spreaders to fill the gap between the two heat spreaders, thereby improving the heat transfer effect and conducting heat to the housing more quickly.

[0063] In order to accelerate the heat dissipation of the battery 16, a sponge gasket 161 is provided on the top of the battery 16, and the sponge gasket 161 can realize the fitting installation of the battery 16 and the shell 11, which can accelerate the heat conduction to the shell 11 and increase the heat dissipation area in contact with the air. The heat dissipation efficiency is high, and the influence of high temperature on the product function and life is reduced.

[0064] In summary, the wireless transmitter of this embodiment assembles the circuit boards in the wireless transmitter together by means of pin header plugging, thereby reducing the size of the wireless transmitter. Moreover, the wireless transmitter has a beautiful appearance, is light in weight, is easy to assemble, and is convenient to use. It can be highly integrated with the electronic endoscope through the connector, and the connection is stable and the signal transmission is stable. In order to solve the problem that the wireless transmitter is small in size and high heat is not easy to dissipate, this embodiment installs a heat spreader on the inner wall of the shell and the wireless module circuit board, so that the heat in the wireless transmitter can be efficiently dissipated through the shell. The heat dissipation structure is simple, does not cause the size of the wireless transmitter to increase, and can reduce the cost of the wireless transmitter.

[0065] It should be noted that although this embodiment takes the application of the wireless transmitter on the electronic endoscope as an example, it is not limited to the application scenario of the electronic endoscope. The wireless transmitter can also be applied to other scenarios that require wireless transmission of data through an appropriate connector, and the wirelessly transmitted data is not limited to image data, but can also be video data.

[0066] The above embodiments are not exhaustive enumerations of the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
