Description

Technical Field

[0001] The present application relates to the technical field of remote control equipment, and in particular to a remote controller. Background Art

[0002] During the use of existing remote controls, the battery will often leak due to long-term idleness or discharge, and the liquid will corrode the PCB board and damage the key gold fingers, thus causing key failure. Therefore, it is particularly important to optimize the structure to protect the PCB board, which can effectively extend the service life of the remote control.

[0003] In order to solve this problem, a known solution adopts a method of adding a leakage baffle on the bottom shell and / or the front shell, and at the same time, a groove is opened on the PCB board, and the PCB board is located outside the leakage baffle board to prevent the battery leakage from contacting the PCB board, thereby reducing the oxidation rate of the PCB board and extending the service life of the remote control.

[0004] However, this solution makes it impossible to set a spring that matches the battery on the PCB. The spring is stuck in the square hole of the PCB, and some space needs to be left for soldering. If the PCB does not have a cantilever support, this gap will inevitably cause the spring to lean to the heavier side like a lever, and tools need to be used to straighten the welding, which increases the difficulty of designing and installing the remote control.

[0030] See also Figures 1 to 8 As shown, according to an embodiment of the present application, the remote control includes a bottom shell 1, a PCB board 2 and a face shell 3, the PCB board 2 is located between the bottom shell 1 and the face shell 3, a battery mounting position 4 is provided on the bottom shell 1, a conductive connector 5 is provided corresponding to the battery mounting position 4, a leakage port 6 is provided at the battery mounting position 4, a solution avoidance port 7 is provided on the PCB board 2 corresponding to the leakage port 6, a solution groove 8 is provided on the face shell 3 corresponding to the leakage port 6, the PCB board 2 includes a main body 9 and a cantilever portion 10, the main body 9 is located outside the solution groove 8, the cantilever portion 10 is located above the solution groove 8, and a solution avoidance port 7 is formed between the cantilever portion 10 and the main body 9, and the conductive connector 5 is provided on the cantilever portion 10.

[0031] For the remote control, generally, the battery leakage can only reach the PCB board 2 through the two holes where the conductive connector 5 is installed, and then can corrode the PCB board 2. Therefore, if you want to avoid battery leakage, you need to consider this point, by adding some structures to block the path of the battery leakage to the PCB board 2, and collect the battery leakage to prevent the battery leakage from flowing around inside the remote control. The above-mentioned conductive connector 5 is, for example, a spring.

[0032] The PCB board 2 is provided with a socket 16, and the spring is provided with a bent portion 17, and the bent portion 17 is inserted into the socket 16. The bent portion 17 is inserted into the socket 16, so that the spring can be clamped and fixed on the PCB board 2, and the spring is conveniently installed and fixed on the PCB board 2. In order to prevent the spring from escaping from the socket 16 from the PCB board 2, the bent portion 17 forms a dovetail structure. Since the bent portion 17 is elastic, when inserted into the socket 16, it can be elastically deformed and contracted to pass through the socket 16, and then under the action of elastic recovery, the tail of the bent portion 17 passing through the socket 16 is expanded and clamped outside the socket 16, preventing the bent portion 17 from escaping from the socket 16, thereby improving the stability and reliability of the spring installation structure on the PCB board 2.

[0033] The spring also includes a support portion, and the support portion 18 is connected to the bending portion 17 and supported on the PCB board 2. The spring includes a conductive portion that cooperates with the battery, wherein the conductive portion is connected to the first end of the bending portion 17, and the support portion 18 is connected to the second end of the bending portion 17. The function of the support portion 18 is to cooperate with the bending portion 17 to ensure that the installation structure of the spring on the PCB board 2 is stable and reliable, and can maintain an upright state, to ensure the contact effect between the spring and the battery, and the problem of the spring falling down will not occur.

[0034] In some embodiments, the support portion 18 is L-shaped, Z-shaped, or straight-shaped.

[0035] The remote control of the present embodiment has modified the PCB board 2 and the face shell 3, formed a solution groove 8 on the face shell 3, and formed a solution avoidance port 7 for avoiding leakage on the PCB board 2, so that the battery leakage can flow from the leakage port 6 through the solution avoidance port 7 into the solution groove 8, and will not flow directly onto the PCB board 2 from the opening of the bottom shell 1, so that the battery leakage can be isolated from the PCB board 2, and the battery leakage of the remote control can be effectively prevented from corroding the PCB board 2. At the same time, since the PCB board 2 in the present application is still partially located above the solution groove 8 and forms a cantilever portion 10, this part of the PCB board 2 structure can be used to design The conductive connector 5 is arranged to facilitate the installation of the conductive connector 5, and makes it easier for the conductive connector 5 to achieve conductive coordination with the battery 15, and at the same time facilitates the conductive connection between the conductive connector 5 and the PCB board 2. The structural modification of the PCB board 2 is relatively small, so that the overall structural strength of the PCB board 2 can be maintained. At the same time, the connection structure between the PCB board 2 and the conductive connector 5 is simpler and easier to implement. There is no need to consider the setting structure of the conductive connector 5 additionally, and the automatic welding of the PCB board can be effectively realized, the problem of the spring tilting can be avoided, and the design and installation difficulty of the remote control can be reduced.

[0036] Since the purpose of the cantilever part 10 is to facilitate the setting of the spring and the conductive connection with the PCB board 2, the conductive connection position between the PCB board 2 and the spring can be set on a structure outside the cantilever part 10. The cantilever part 10 plays a role in supporting and positioning the spring. No circuit structure is set on the cantilever part 10, thereby preventing the battery leakage flowing onto the cantilever part 10 from corroding the circuit structure on the cantilever part 10.

[0037] By adding a solution groove 8 to the face shell 3, after the battery 15 leaks, the battery leakage is guided to the cantilever portion 10 of the PCB board 2 through the spring. The cantilever portion 10 of the PCB board 2 contacted by the battery leakage is located above the solution groove 8, and the PCB board 2 is provided with a solution avoidance port 7 at a position corresponding to the leakage port 6 above the solution groove. Under the isolation effect of the solution avoidance port 7, the battery leakage reaching the cantilever portion 10 will flow into the solution groove 8 and be collected in the solution groove 8, thereby forming a first line of protection, avoiding the problem that the battery leakage reaches the main body 9 of the PCB board 2 through the cantilever portion 10 and causes corrosion to the PCB board 2, thereby forming an effective protective effect on the main body 9 of the PCB board 2.

[0038] The cantilever portion 10 is supported on the side wall of the solution tank 8, and the side wall of the solution tank 8 can be used to support the cantilever portion 10, thereby avoiding the poor structural stability of the cantilever portion 10 due to being suspended in the air, making the installation structure of the cantilever portion 10 more stable and reliable, and improving the stability and reliability of the overall structure of the entire PCB board 2.

[0039] Grooves 11 are provided on two opposite side walls of the solution tank 8, and the cantilever part 10 falls into the grooves 11. By providing the grooves 11, the cantilever part 10 can fall into the grooves 11, and the cantilever part 10 is installed and positioned by the grooves 11, and at the same time, the cantilever part 10 can be more effectively located in the solution tank 8, so that the battery leakage flowing to the cantilever part 10 can flow into the solution tank 8 more effectively, avoiding corrosion to the main body 9 of the PCB board 2, and improving the service life of the PCB board 2. The two opposite side walls of the solution tank 8 where the grooves 11 are provided are located at the two connecting ends of the cantilever part 10, which can play a role in supporting and positioning the cantilever part 10. The cantilever part 10 here is a long strip plate-like structure, and its main function is to support and position the conductive connector 5.

[0040] The end of the PCB board 2 forms a U-shaped groove, the solution groove 8 is located in the U-shaped groove, and the cantilever part 10 is connected to the side wall of the U-shaped groove. The U-shaped groove structure is more convenient for isolating the main body 9 of the PCB board 2 from the inner area of ​​the solution groove 8, and is also convenient for setting the cantilever part 10.

[0041] The bottom shell 1 is also provided with a pressing portion 12, and the cantilever portion 10 is located between the pressing portion 12 and the solution tank 8, and is pressed and fixed by the pressing portion 12 and the side wall of the solution tank 8. Through the cooperation between the pressing portion 12 and the side wall of the solution tank 8, the cantilever portion 10 can be pressed and positioned, so as to prevent the cantilever portion 10 from shaking during use, improve the stability of the installation structure of the cantilever portion 10, and at the same time make the structure of the spring located on the cantilever portion 10 more stable, so as to form a good conductive cooperation with the battery 15. In addition, the stable positioning of the cantilever portion 10 is also conducive to preventing the cantilever portion 10 from shaking and swinging the battery leakage to other positions, so as to prevent the battery leakage from flowing everywhere.

[0042] In order to further improve the stability and reliability of the installation position of the conductive connector 5 , in this embodiment, a slot 13 is provided on the side of the pressing portion 12 facing the battery installation position 4 , and the conductive connector 5 is snap-fitted and fixed in the slot 13 .

[0043] The ribs 14 are arranged around the leakage port 6 of the bottom shell 1. The ribs 14 extend toward the solution tank 8. The main body 9 of the PCB board 2 is located on the side of the ribs 14 away from the solution tank 8. When the battery leakage does not pass through the spring diversion, it will flow down from all parts of the leakage port 6. Therefore, there is a risk that the solution will flow along the bottom shell 1 to the main body 9 of the PCB board 2. By setting the ribs 14, the ribs 14 can be used to form a barrier effect. When the battery leakage flows to the leakage port 6, it can flow into the solution tank 8 under the blocking and diversion effect of the ribs 14 at the leakage port 6. Here, the ribs 14 play the role of blocking the flow route of the battery leakage. After adding the ribs 14, the battery leakage will be diverted to the solution tank by the ribs 14 when passing through, thereby forming a second line of protection.

[0044] The retaining rib 14 includes a confluence portion, the width of which decreases along the direction away from the bottom shell 1, and a tip is formed at the end, which can play a good role in collecting the battery leakage, so that the battery leakage can be gathered into a water drop shape at the tip of the end of the confluence portion, and it is easier to drip into the solution tank 8, thereby improving the guiding effect of the retaining rib 14. The end of the retaining rib 14 can form a triangular structure, a trapezoidal structure, etc.

[0045] The retaining rib 14 is arranged on the side of the leakage port 6 away from the cantilever portion 10 and extends into the solution tank 8, and the side wall of the solution tank 8 is located between the main body 9 and the retaining rib 14. Since the retaining rib 14 extends into the solution tank 8, the height of the side wall of the solution tank 8 is higher than the bottom of the retaining rib 14. When the battery leakage flows to the bottom of the retaining rib 14, it cannot flow to the main body 9 located outside the solution tank 8 due to the blocking effect of the side wall of the solution tank 8. Therefore, a good protective effect can be formed on the main body 9 to prevent the battery leakage from corroding the PCB board 2.

[0046] In another embodiment, the retaining rib 14 is disposed on a side of the liquid leakage port 6 close to the cantilever portion 10 , and is located on a side of the cantilever portion 10 facing the main body 9 .

[0047] The retaining rib 14 can be set at the above-mentioned two positions at the same time, so that a barrier can be formed on the side of the main body 9 facing the solution tank 8 and the side of the cantilever portion 10 facing the solution tank 8, completely blocking the path of the battery leakage to the PCB board 2, and more effectively preventing the battery leakage from flowing to the PCB board 2, so that neither the main body 9 nor the cantilever portion 10 will form contact with the battery leakage, so that the PCB board 2 forms a better leakage isolation effect, and more effectively prevents the battery leakage from corroding the PCB board 2.

[0048] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0049] 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 shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
