[0001] This utility model relates to the technical field of photography, and in particular to a wireless remote control. Background Technology

[0002] Currently, there are various types of remote controls available for photography equipment, capable of functions such as shooting, recording, and zooming. However, the zoom function often provides slow feedback to the user, requiring a significant amount of time and resulting in low shooting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a wireless remote control that can quickly achieve zoom function, thereby significantly improving shooting efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A knob-type wireless remote control, comprising:

[0006] The main body and a rotary switch, wherein the rotary switch is rotatably mounted on the main body.

[0007] The main body includes a front housing, and a recess is formed at the upper end of the front housing, and the rotary switch is correspondingly installed in the recess;

[0008] The rotary switch is fastened to the front housing, and a connecting shaft is provided on the back of the rotary switch. The connecting shaft is rotatably inserted into the main body, thereby enabling the rotary switch to rotate relative to the main body.

[0009] Furthermore, the back of the rotary switch is provided with multiple hooks, and a circular hole is provided in the center of the recess. The inner side of the circular hole is provided with a buckle that cooperates with the multiple hooks along the circumferential direction.

[0010] The hook engages with the buckle to secure the rotary switch at the circular hole in the front housing.

[0011] Furthermore, the rotary switch is squeezed and deformed during the process of being fastened to the front housing to store elastic force. After the rotary switch is fastened to the front housing, the multiple hooks release the elastic force and spring back, thereby locking in the circular hole.

[0012] Furthermore, the plurality of hooks are spaced apart, and a stop is formed between two adjacent hooks, the stop abutting against the side wall of the circular hole.

[0013] Furthermore, there are four hooks and four stops, which are staggered and arranged in a circular pattern with equal spacing.

[0014] Furthermore, the main body includes a control circuit board, the front of which is provided with an encoder body and multiple function buttons, and the encoder body is provided with a shaft hole that mates with the connecting shaft.

[0015] When the rotary switch is turned, the connecting shaft rotates within the shaft hole, thereby converting the rotational action into a control command.

[0016] Furthermore, the lower end of the front housing has multiple button holes, and the multiple function buttons pass through the multiple button holes and protrude from the surface of the front housing.

[0017] Furthermore, the main body includes a rear housing and a battery, the battery being electrically connected to the back of the control circuit board and nested within the rear housing.

[0018] Furthermore, a plug is fixed on the back of the control circuit board, and a sleeve is formed on the rear housing corresponding to the position of the plug, and the plug is inserted into the sleeve.

[0019] Furthermore, the main body also includes a battery cover, the lower end of which is provided with a sleeve ring, and the flange at the end of the insertion post is sleeved with the battery cover.

[0020] Compared with the prior art, the rotary wireless remote control involved in this utility model has at least the following beneficial effects:

[0021] With the rotary switch engaged with the main body, the control circuit board, in conjunction with the front housing, exerts a vertical constraint force on the rotary switch, preventing the multiple latches of the rotary switch from detaching from the front housing. Simultaneously, in the horizontal direction, because a stop is spaced between each pair of adjacent latches, the rotary switch is horizontally limited when it is turned, thus preventing it from wobbling during rotation. Therefore, the wireless remote control of this invention enables users to quickly achieve zoom functionality, significantly improving shooting efficiency. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figures 1-4 As shown, the wireless remote control 100 of this utility model includes a main body 1 and a rotary switch 3 rotatably mounted on the main body 1. The main body 1 includes a front housing 10, a rear housing 20, a control circuit board 30, and a battery cover 40. The front housing 10 is mounted on the front of the main body 1, the rotary switch 3 is mounted on the upper end of the front housing 10, and the battery cover 40 is mounted on the back of the main body 1.

[0032] Please also refer to Figure 3 and Figure 4 The front housing 10 is a plastic shell made of materials such as polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS), and is integrally formed by injection molding or the like. A circular recess 11 is formed at the upper end of the front housing 10, and multiple button holes 12 are formed at the lower end of the front housing 10. Furthermore, multiple locking protrusions 13 are formed on the inner sidewall of the front housing 10. These locking protrusions 13 are used to secure the front housing 10 and the rear housing 20 together.

[0033] Furthermore, a circular hole 14 is further formed on the bottom surface of the recess 11. A fastener 140 is formed on the inner side of the circular hole 14 along the circumferential direction. The fastener 140 is formed around the circular hole 14 on the inner surface of the front housing 10. The circumferential wall of the circular hole 14 has a bevel. That is, the opening of the circular hole 14 is formed as a bevel.

[0034] The rotary switch 3 is installed within the recess 11 and can rotate clockwise or counterclockwise within the recess 11 under external force. The front of the rotary switch 3 has indicator icons 301 for adjusting focus, etc. Users can move the rotary switch to the desired position according to the indicator icons 301 to achieve the corresponding function. Multiple protruding ribs 302 are formed on the circumferential wall of the rotary switch 3, giving it a shape similar to a soda bottle cap. The protruding ribs 302 increase the friction with the user's fingers, making it easier for the user to operate the rotary switch 3. Figure 4 As shown, a ring of hooks 303 protrudes from the inner surface of the rotary switch 3 toward the circular hole 14 of the front housing 10. Multiple hooks 303 are spaced apart, and a stop 305 is formed between adjacent hooks 303. The stop 305 abuts against the side wall of the circular hole 14. A connecting shaft 307 is formed at the center of the ring of hooks 303. The connecting shaft 307 extends vertically from the back of the rotary switch 3 toward the control circuit board 30. The multiple hooks 303 can be respectively fastened to the corresponding fasteners 140 of the circular hole 14. Furthermore, since the opening of the circular hole 14 is beveled, during assembly, the front end of the hooks 303 of the rotary switch 3 can easily push open the bevel at the opening of the circular hole 14, thus smoothly engaging into the circular hole 14.

[0035] The rear housing 20 is preferably integrally formed from a robust resin component. A battery 50 is disposed on the back of the control circuit board 30 and is fixed within the rear housing 20. In this embodiment, the battery 50 is a button cell battery and is electrically connected to the power circuit of the control circuit board 30 to power the entire wireless remote controller 1. A receiving hole 23, matching the size of the battery 50, is formed on the rear housing 20 corresponding to the position of the battery 50, for nesting the battery 50 within it. A sleeve 25 is formed below the receiving hole 23. Multiple engaging holes 210 are also formed on the side wall of the rear housing 20.

[0036] Below the battery 50, a cylindrical insertion post 32 is provided, extending from the back of the control circuit board 30. The insertion post 32 passes through the sleeve 25, and its end flange engages with the retaining ring 41 located at the lower end of the battery cover 40. Therefore, by providing the insertion post 32, the control circuit board 30, the rear housing 20, and the battery cover 40 can be reliably connected together.

[0037] An encoder body 31 is located near the top of the control circuit board 30, and multiple function buttons 33 are fixed near the bottom. The encoder body 31 is an irregularly shaped block with a hexagonal shaft hole 310 formed inside. The connecting shaft 307 of the rotary switch 3 is rotatably inserted into the shaft hole 310. Since the outer peripheral wall of the connecting shaft 307 has six surfaces that fit into the shaft hole 310, when the user turns the rotary switch 3, the connecting shaft 307 can rotate within the shaft hole 310. The encoder body 31 then interprets the rotation as a control command, thereby generating a control command. That is, the rotary switch 3, as a rotatable control button, causes the encoder body 31 to generate a corresponding control command through the rotation of the connecting shaft 307, which protrudes and extends from its back. For example, in this embodiment, the control command is to control the focal length to increase or decrease. The multiple function buttons 33 can be a shooting button, a menu button, or a power button, etc. The multiple function buttons 33 pass through multiple button holes 12 of the front housing 10 and protrude from the surface of the front housing 10 for users to press.

[0038] Understandably, the inner surface of the shaft hole 310 is not limited to hexagonal, but can also be pentagonal or octagonal. Correspondingly, the outer peripheral wall of the connecting shaft 307 is not limited to having six faces, as long as it can match the shaft hole 310 and stay in different positions within the shaft hole 310.

[0039] In addition, the control circuit board 30 integrates a wireless communication module, which is used to transmit wireless signals with external electronic devices or household appliances.

[0040] The following is for reference. Figure 3 , Figure 4 as well as Figure 5 The assembly process of the wireless remote controller 100 of this utility model will be described.

[0041] During assembly, firstly, the control circuit board 30 is assembled with the rear housing 20 via the insertion post 32, allowing the battery 50 to be inserted into the receiving hole 23 of the rear housing 20. Secondly, multiple locking protrusions 13 located on the side wall of the front housing 10 are engaged with multiple engaging holes 210 located on the side wall of the rear housing 20, thereby assembling the front housing 10 onto the rear housing 20. Thirdly, the rotary switch 3 is fastened and fixed onto the front housing 10. Specifically, pressing the rotary switch 3 toward the front housing 10 causes the front ends of multiple hooks 303 on the back of the rotary switch 3 to push open the inclined surface of the opening of the circular hole 14 of the front housing 10. During this process, each hook 303 stores elastic force through compression deformation. When the entire rotary switch 3 passes through the circular hole 14 and is fastened in place, each hook 303 on the rotary switch 3 releases its elastic force and springs back, thereby locking into the circular hole 14 of the front housing 10, thus completing the fastening of the rotary switch 3 with the main body 1. Finally, attach the battery cover 40 to the back of the rear housing 20 using a snap-fit ​​mechanism to complete the assembly of the wireless remote control 100.

[0042] After engagement, the hooks 303 on the rotary switch 3 will engage and be fixed on the latches 140 around the circular hole 14. The front housing 10 exerts a vertical constraint force on the rotary switch 3, preventing the hooks 303 from detaching from the front housing 10. Simultaneously, in the horizontal direction, since a stop 305 is spaced between each pair of adjacent hooks 303, the sidewall of the circular hole 14 of the front housing 10 and the stop 305 generate friction through an interference fit. This provides damping and limits the rotation of the rotary switch 3 in the horizontal direction, preventing it from wobbling during rotation. Furthermore, the rotary switch 3 is connected to the encoder body 31 on the control circuit board 30 via a connecting shaft 307 at the center of its back. During the rotation of the rotary switch 3, the connecting shaft 307 rotates within the shaft hole 310, allowing the encoder body 31 to receive control commands. These control commands enable functions such as taking pictures and zooming. Furthermore, as the connecting shaft 307 rotates to different angles, the ends of the plurality of hooks 303 move along the circumference of the circular hole 14 and generate a certain amount of friction with the inner surface of the front housing 10; at the same time, a certain amount of friction is also generated between the stop block 305 and the side wall of the circular hole 14. Thus, through the shape design of the hooks 303, the stop block 305, and the connecting shaft 307, the rotary switch 3 can be positioned in different positions.

[0043] Furthermore, in the assembled state, the battery cover 40 can be easily removed from the rear housing 20 to replace the battery 50. When installing the battery 50, insert it from the back of the rear housing 20, and then replace the battery cover 40.

[0044] In summary, in this invention, the front housing 10 of the wireless remote controller 1 is equipped with a rotary switch 3, which enables the corresponding functions by rotating the rotary switch 3. The installation of the rotary switch 3 and the front housing 10 is very simple. Specifically, the top of the hook 303 on the inner surface of the rotary switch 3 is inclined, and the edge of the circular hole 14 that mates with it is also beveled. During installation, the hook 303 is compressed and deformed to store elastic force, and releases the elastic force after opening the circular hole 14, thus completing the engagement. The rotary switch 3 cannot detach from the main body 1, and it is not prone to wobbling in the horizontal direction, making it easy for users to assemble and ensuring a robust structure. Furthermore, the wireless remote controller of this invention allows users to quickly adjust the focus by rotating the rotary switch, significantly improving shooting efficiency.
