Description

Technical Field

[0001] The utility model relates to the technical field of control instruments, in particular to a back key assembly and an operating handle. Background Art

[0002] A controller is a device that converts human hand movements into computer commands. It is often used in electronic games and unmanned equipment control. Specifically, users can convert human hand movements into electrical signals by operating the joystick or buttons on the controller, thereby controlling the virtual characters in the game, or controlling the forward, backward, stop, and other actions of remote unmanned equipment. Buttons are common parts on controllers, usually a back key assembly composed of many buttons and related parts, which serves as an extension of the operating handle.

[0003] In the prior art, the back key assembly is installed in the operating handle, including structures such as the back key, the support, and the trigger switch. The back key is engaged on the support and protrudes outward. The operator can press the back key to make the back key move relative to the support and press the trigger switch, thereby generating an electrical signal through the relevant circuit board and circuit structure. The back key is generally connected to the support through a mounting seat or a mounting frame to achieve that the back key is fixed on the support and can also achieve a certain range of movement or rotation as needed. The structure of the mounting seat affects the pressing feel of the back key, and also determines the structural complexity of the back key assembly to a certain extent. How to achieve a simple mounting seat structure while ensuring that the back key thereon can rotate flexibly is a project that needs continuous improvement. Utility Model Content

[0035] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described can be included in at least one implementation of the utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] The embodiment of the first aspect of the present application provides a back key assembly, such as Figure 1 to Figure 5As shown, installed on the shell 200 of the operating handle, the back key assembly includes: a back key group 100, which is protruding from one side of the shell 200; and a mounting base 300, which is arranged on the other side opposite to the shell 200 and includes a mounting end 310 and a support arm 320, the mounting end 310 is connected to the back key group 100, and at least two mounting ends 310 are arranged on the shell 200, at least two mounting ends 310 are connected as a whole through the support arm 320, and the resilient support arm 320 is detachably connected to the shell 200. The function of the mounting base 300 is to mount the back key group 100 on the housing 200 so as to facilitate the back key on the back key group 100 to be pressed. The mounting end 310 on the mounting base 300 corresponds to the back key group 100. Specifically, the mounting base 300 includes an integrally connected support arm 320 and a plurality of mounting ends 310. The mounting end 310 is integrally connected to the support arm 320, and the resilient support arm 320 is detachably connected to the housing 200. Usually, one mounting end 310 corresponds to a back key on the back key group 100 to achieve the operational independence of the back keys. Optionally, in some specific implementations, the symmetry center of the support arm 320 is detachably connected to the housing 200. The symmetry center includes an axially symmetrical center position and also includes a centrosymmetric center position.

[0037] The mounting base 300 adopts an integrally connected mounting end 310 and a support arm 320, which has a simple structure and is easy to assemble and produce. The support arm 320 has a rebound property, so that the mounting ends 310 at both ends of the support arm 320 can have better rebound characteristics to a certain extent, helping the rebound and reset of the back key on the mounting end 310.

[0038] The back key assembly provided by the utility model adopts a mounting base 300 in which a mounting end 310 and a support arm 320 are integrally connected. The support arm 320 has a rebound characteristic, which can cooperate with the mounting end 310 to install the back key in the back key assembly on the shell 200 of the operating handle, and can also rebound and reset more quickly after the back key is pressed. The integrated connection structure can simplify the structure of the mounting base 300, which can not only ensure the good installation of the mounting base 300 on the back key group 100, thereby allowing the back key to move flexibly, but also greatly reduce the overall structural complexity of the back key assembly.

[0039] Optionally, in some implementations of the first aspect of the present application, such as Figure 2 to Figure 5 As shown, the mounting end 310 includes a first mounting end 311 and a second mounting end 312, and the first mounting end 311 and the second mounting end 312 are spaced apart on both sides of the symmetry center of the support arm 320, and the back key group 100 includes a first left back key 110 connected to the first mounting end 311, and a first right back key 130 connected to the second mounting end 312.

[0040] In combination with the above implementation, in a further implementation of the first aspect, the mounting end 310 includes a third mounting end 313 and a fourth mounting end 314, the third mounting end 313 and the first mounting end 311 are arranged on the same side of the symmetry center of the support arm 320, and the fourth mounting end 314 and the second mounting end 312 are arranged on the other side opposite to the symmetry center of the support arm 320; the back key group 100 includes a second left back key 120 connected to the third mounting end 313, and a second right back key 140 connected to the fourth mounting end 314.

[0041] The mounting base 300 may be one or more. The two mounting bases 300 are distributed on the shell 200, presenting a symmetrical posture. This symmetrical posture includes mirror symmetry and central symmetry. The two mounting bases 300 may be completely separated, partially overlapped, or partially shared. The two are combined into one, and the two are combined into one at the symmetry center of the support arm 320. A more specific implementation method will be introduced later. One of the characteristics of the back key assembly provided in this implementation method is that the mounting base 300 is generally presented as two parts, and one mounting base 300 can be used to fix the left back key group, and the other mounting base 300 can be used to fix the right back key group, that is, the first mounting end 311 and the third mounting end 313 cooperate with the left back key group so that the left back key group is connected to the shell 200, and the second mounting end 312 and the fourth mounting end 314 cooperate with the right back key group so that the right back key group is connected to the shell 200.

[0042] Optionally, in combination with the embodiment of the first aspect and the above implementation, in a first specific implementation of the embodiment of the first aspect, as Figure 2 As shown, the support arm 320 is in the shape of an elongated strip, and the support arm 320 connected between the first mounting end 311 and the second mounting end 312 is parallel to the support arm 320 connected between the third mounting end 313 and the fourth mounting end 314. It can be seen that the upper and lower mounting seats 300 have similar structures, and both are elongated strips as a whole, and more specifically, each is in the shape of a dumbbell. The middle position of the support arm 320 is provided with a through hole, and the support arm 320 is fixed with bolts or screws, thereby fixing the mounting seat 300 to the mounting shell. When the back key is pressed, the mounting end 310 protrudes relative to the housing 200, and the integrally connected support arm 320 will be elastically bent, the middle of the support arm 320 remains in place, and the two ends are tilted, and the entire support arm 320 will bend. When the back key is released, under the action of the elastically bent support arm 320, the mounting ends 310 at both ends will be driven to reset.

[0043] Optionally, in combination with the embodiment of the first aspect and the above implementation, in a second specific implementation of the embodiment of the first aspect, as Figure 3As shown, the support arm 320 is U-shaped, and the support arm 320 connected to the first mounting end 311 and the third mounting end 313 is opposite to the opening of the support arm 320 connected to the second mounting end 312 and the fourth mounting end 314. In this implementation, the mounting bases 300 corresponding to the left back key group 100 and the right back key group 100 are independent of each other, the first mounting end 311 and the third mounting end 313 correspond to the left back key group 100, and the second mounting end 312 and the fourth mounting end 314 correspond to the right back key group 100, and the two do not interfere with each other. Two back keys are arranged on each back key group 100, and each back key corresponds to a mounting end 310.

[0044] Optionally, in combination with the embodiment of the first aspect and the above implementation, in a third specific implementation of the embodiment of the first aspect, as Figure 4 As shown, the support arm 320 connected to the first mounting end 311 and the fourth mounting end 314 is cross-stacked with the support arm 320 connected to the second mounting end 312 and the third mounting end 313, and the intersection of the support arms 320 is connected to the housing 200. The two support arms 320 are distributed in an X shape, or a scissor-shaped distribution, the first mounting end 311 and the fourth mounting end 314 are a centrally symmetrical distribution, and the second mounting end 312 and the third mounting end 313 are also a centrally symmetrical distribution. This structure can simplify the connection parts of the support arm 320 fixed to the housing 200, only one bolt or screw is needed, and the structure of the single mounting base 300 can also be very simple.

[0045] Optionally, in combination with the embodiment of the first aspect and the above implementation, in a fourth specific implementation of the embodiment of the first aspect, as Figure 5 As shown, the support arm 320 connected to the first mounting end 311, the second mounting end 312, the third mounting end 313 and the fourth mounting end 314 is an integrated structure. In this implementation, the mounting seat 300 is an integrated structure, that is, only one mounting seat 300 is used, and it is similar to the cross structure of the third specific implementation, but the support arm 320 in this implementation is made of a piece of material instead of two separable materials. The mounting seat 300 of this structure has a more streamlined structure, and only a through hole needs to be opened in the middle of the mounting seat 300, and the entire mounting seat 300 can be quickly installed on the housing 200 by bolts or screws.

[0046] Optionally, in combination with the embodiment of the first aspect and the above implementation, in some further specific embodiments of the first aspect, such as Figure 6 to Figure 8As shown, the back key assembly also includes a circuit board; the mounting end 310 includes a bracket 310a, a locking pin 310b and a flexible body 310c, the bracket 310a and the locking pin 310b are respectively connected to the flexible body 310c, and form a slot for locking the back key group 100 with the flexible body 310c, so that the back key group 100 can be detachably connected to the mounting end 310, and the mounting end 310 is movably connected to the housing 200; the back key group 100 abuts against the circuit board through the flexible body 310c. The mounting end 310 mainly includes the locking pin 310b and the flexible body 310c, as well as the bracket 310a integrally connected to one end of the support arm 320, etc. The support arm 320 can be regarded as a part of the mounting end 310, and the support arm 320 mainly plays the role of connecting the entire mounting seat 300 to the housing 200 and limiting the back key.

[0047] The circuit board is provided with a trigger switch 400 corresponding to each back key in the back key assembly, and the flexible body 310c in the mounting end 310 is arranged near the trigger switch 400, so that when the back key is pressed by a finger, the rotating shaft installed in the bracket 310a on the back key rotates, driving the pressing engagement pin 310b, the engagement pin 310b, the bracket 310a and the flexible body 310c to be connected as a whole, thereby driving the bracket 310a and the flexible body 310c to move as a whole, protruding toward the inside of the housing 200, so that the flexible body 310c presses the trigger switch 400 on the circuit board to generate a trigger signal. The bracket 310a can be made of hard plastic, specifically hard plastic with a hardness higher than 90A of Shore hardness, and the flexible body 310c can be made of soft plastic, such as silicone, rubber, etc., with a hardness less than 90A of Shore hardness. The locking pin 310b can be a metal part in a cylindrical shape, which is inserted into a special hole groove of the flexible body 310c, and a pressing portion that abuts against the locking pin 310b is provided on the back key. It should be noted that the support arm 320 can be made of metal, for example, a metal plate made of spring steel, and the bracket 310a can be embedded and fixed with the edge of the metal plate.

[0048] In a second aspect, the present application provides an operating handle, comprising a housing and a back key assembly as described in any one of the first aspects of the present application. The housing is used to contain various components of the operating handle, including the back key assembly and mounting seat.

[0049] By adopting the back key assembly described in the first aspect of the present application, the operating handle of the present application has the characteristics of simple structure, easy production and manufacturing, reliability and stability. At the same time, since the mounting base adopts a structure in which the mounting end and the support arm are integrally connected, the support arm has a rebound characteristic, which can ensure that the back keys in the back key group rebound quickly and have a good damping feel when pressed.

[0050] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
