Description

Technical Field

[0001] This utility model relates to the field of remote control technology, specifically to a remote control. Background Technology

[0002] Remote controls, as control devices used for remotely controlling electronic devices, are widely used in automotive electronics, home appliances, smart homes, and security monitoring. For example, in the automotive industry, remote controls are typically an important component of car keys or keyless entry systems, used to lock / unlock doors, open the trunk, and locate the vehicle. In home appliances, air conditioners, televisions, set-top boxes, and audio equipment commonly rely on remote controls for power on / off, mode switching, and function adjustments. In smart home and security systems, remote controls are also frequently used for arming / disarming, scene switching, and controlling terminal devices such as door locks and lighting.

[0003] Taking car remote controls as an example, users usually carry the remote control along with their car keys in their pockets. This places higher demands on the size and thickness of the remote control: on the one hand, it needs to have a good grip and convenient button operation, and on the other hand, it is desirable for the remote control to be as thin and compact as possible so as not to significantly enlarge the pocket or affect the appearance.

[0004] In existing technologies, the circuit board is typically installed inside the casing, while the battery is mounted on the circuit board, and the positive and negative electrode contacts are generally formed on the circuit board. The battery and circuit board are installed in a stacked structure. This structure results in the remote control occupying a large amount of space in the thickness direction, making the remote control thicker and larger, which is not conducive to carrying it with the user.

[0005] Especially in the application scenario of car remote controls, the thick remote controls tend to stretch the pocket when put in a pocket, affecting aesthetics and comfort, and failing to meet the market demand for thinner and more portable products. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and provide a remote control.

[0007] To achieve the objectives of this utility model, the following technical solution is adopted: A remote control includes a housing, a circuit board and a battery disposed within the housing, and a first spring and a second spring electrically connecting the battery and the circuit board, wherein the circuit board and the battery are arranged horizontally side by side within the housing.

[0008] Preferably, the housing has a circuit board fixing slot and a battery compartment arranged horizontally parallel to the circuit board fixing slot; the circuit board is inserted into the circuit board fixing slot, and the battery is inserted into the battery compartment.

[0009] More preferably, the circuit board has an arc-shaped portion at one end near the battery compartment; the arc-shaped portion fits into the arc-shaped outer wall of the battery compartment.

[0010] More preferably, the battery compartment has an annular inner sidewall with an opening that communicates with the circuit board fixing groove; the first spring has an arc-shaped terminal piece and a bent portion formed on the arc-shaped terminal piece; the arc-shaped terminal piece is attached to the annular inner sidewall, and the bent portion extends through the opening into the circuit board fixing groove and is electrically connected to the circuit board.

[0011] Alternatively, a positioning groove is formed on the inner sidewall of the annular structure, the opening is located in the positioning groove, and the arc-shaped terminal piece is inserted into the positioning groove.

[0012] Furthermore, a connecting piece is provided between the arc-shaped terminal piece and the bent portion.

[0013] Preferably, the battery compartment has a bottom wall with a window formed thereon; the second spring has a terminal branch and a fixing part connected to the terminal branch; the terminal branch is disposed on the bottom wall, and the fixing part passes through the window and enters the circuit board fixing groove, and is electrically connected to the circuit board.

[0014] More preferably, an extension piece is formed between the terminal branch and the fixing part.

[0015] Furthermore, the first spring is a positive electrode spring, and the second spring is a negative electrode spring.

[0016] Preferably, it further includes a battery cover that snaps onto the battery compartment.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows: In this invention, by changing the arrangement of the circuit board and battery from "stacked vertically" to "side-by-side horizontally", the thickness of the remote control is reduced from "circuit board thickness + battery thickness" to "the larger of the two", which significantly reduces the overall thickness of the remote control geometrically, making the remote control smaller and more compact.

[0018] Furthermore, by utilizing the electrical connection between the first and second spring contacts and the circuit board and battery, even if the circuit board and battery are no longer stacked on top of each other, the circuit connection can still be ensured to be stable and reliable. Thus, without sacrificing electrical performance and reliability, the internal structure of the remote control can be optimized and its thickness reduced.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0027] See Figure 1-4 A remote control 100 generally includes a housing 20 for carrying internal functional components, a circuit board 10, a battery 30, and a first spring 40 and a second spring 50 electrically connected to the battery 30 and the circuit board 10, respectively, installed in the housing 20.

[0028] The circuit board 10 can be a conventional rigid circuit board used to implement various control functions of the remote control; the battery 30 is preferably a button battery or a thin battery, providing power to the circuit board 10; the first spring 40 and the second spring 50 serve as elastic conductive elements for the positive and negative terminals of the battery. The circuit board 10 and the battery 30 are arranged side by side in the transverse direction inside the housing 20, rather than stacked vertically along the thickness direction, thereby effectively controlling the size of the remote control 100 in the thickness direction.

[0029] In one embodiment, the internal space of the housing 20 is divided into two laterally adjacent functional areas: one side forms a circuit board fixing groove 27 for accommodating and positioning the circuit board 10, and the other side forms a battery compartment 22 laterally adjacent to it. During assembly, the circuit board 10 is inserted or snapped into the circuit board fixing groove 27, and the battery 30 is pressed in from the opening of the battery compartment 22 and snapped into the battery compartment 22, thereby realizing the lateral side-by-side arrangement of the circuit board 10 and the battery 30 within the housing 20.

[0030] The circuit board fixing slot 27 can provide better positioning and support for the circuit board 10, preventing the circuit board from becoming loose or dislodged due to external forces such as drops or shaking during the use of the remote control; the battery compartment 22 provides a shape-matched housing space for the battery 30, so that the battery can remain stably in the predetermined position when subjected to external vibration, and is not easy to fall off, ensuring the normal operation of the remote control.

[0031] Since the circuit board fixing slot 27 and the battery compartment 22 are arranged side by side in the horizontal direction, the circuit board 10 and the battery 30 no longer overlap in the thickness direction. This avoids the thickness accumulation that is inevitable in the traditional top and bottom laminated structure, which significantly reduces the thickness of the entire remote control 100. While ensuring the integrity of the internal functions, the product is made flatter and more compact, which is conducive to users carrying it with them.

[0032] In this embodiment, the end of the circuit board 10 near the battery compartment 22 is preferably machined into an arc-shaped portion 12 that matches the shape of the battery compartment 22. This arc-shaped portion 12 fits tightly against the arc-shaped outer wall of the battery compartment 22. The arc transition makes the contour of the circuit board 10 on the side near the battery 30 fit the contour of the battery compartment 22 more closely, thereby shortening the longitudinal length occupied by the circuit board 10 in the housing 20, further reducing the overall length of the remote control 100, which is beneficial to the compact design of the remote control.

[0033] In a preferred embodiment, the inner periphery of the battery compartment 22 forms an annular inner sidewall 224, and an opening 2242 communicating with the circuit board fixing groove 27 is provided on the annular inner sidewall 224. The first spring tab 40 includes an arc-shaped terminal piece 42 arranged arcuately along the sidewall of the battery and a bent portion 46 provided on the arc-shaped terminal piece 42. During assembly, the arc-shaped terminal piece 42 is arranged close to the annular inner sidewall 224, and the bent portion 46 extends through the opening 2242 toward the circuit board fixing groove 27 and is electrically connected to the conductive pads or conductive lines on the circuit board 10, thereby forming a reliable conductive path between the battery 30 and the circuit board 10.

[0034] The arc-shaped terminal piece 42 can be adapted to the shape of the battery 30 to increase the contact area with the side of the battery. It can usually be made of metal materials with good elasticity and conductivity, such as phosphor bronze, stainless steel or nickel-plated steel sheet.

[0035] The opening 2242 allows a portion of the first spring tab 40 to span the partition between the battery compartment 22 and the circuit board mounting slot 27, thus achieving a conductive connection between the battery compartment and the circuit board mounting slot. In this invention, the shape and size of the opening 2242 are not limited, as long as the bent portion 46 can pass through smoothly. For example, it can be designed as a semi-closed window-like notch, or a completely closed circular hole, elliptical hole, or elongated hole, to adapt to different processing methods and structural strength requirements.

[0036] Furthermore, a positioning groove 2244 can be recessed on the annular inner sidewall 224, with an opening 2242 disposed within the positioning groove 2244. During assembly, the arc-shaped terminal piece 42 is partially embedded in the positioning groove 2244. This allows for axial and radial positioning of the arc-shaped terminal piece 42, preventing it from shifting or rotating during use. Furthermore, since the arc-shaped terminal piece 42 does not protrude inward from the inner surface of the annular inner sidewall 224, it does not occupy the effective inner diameter space of the battery compartment 22. This ensures that the inner diameter of the battery compartment 22 is essentially consistent with the outer diameter of the battery 30, eliminating the need to increase the diameter of the battery compartment 22 to accommodate the spring clip, thus making the entire structure more compact.

[0037] In another embodiment, the arc-shaped terminal piece 42 and the bent portion 46 can be connected by a connecting piece 44. The connecting piece 44 can be regarded as a transition extension on the first spring piece 40. By changing the length and shape of the connecting piece 44, the relative distance and height between the arc-shaped terminal piece 42 and the bent portion 46 in space can be easily adjusted, so that the bent portion 46 can reliably extend to the corresponding soldering or contact position on the circuit board 10 without significantly increasing the length of the circuit board 10. In this way, while ensuring electrical connection, it is possible to avoid extending the circuit board 10 too much towards the battery to meet the contact requirements of the spring piece, thereby further shortening the size of the circuit board 10 and making the overall structure of the remote control 100 more compact.

[0038] In one embodiment, the bottom region of the battery compartment 22 forms a bottom wall 222, and a window 2222 is provided on the bottom wall 222. The second spring 50 includes a terminal branch 52 arranged on the bottom wall 222 and a fixing part 58 connected to the terminal branch 52 and extending through the window 2222 into the circuit board fixing groove 27.

[0039] During assembly, the terminal stub 52 is arranged on the inner surface of the bottom wall 222. After the battery 30 is installed into the battery compartment 22, the bottom of the battery 30 makes elastic contact with the terminal stub 52. The fixing part 58 protrudes through the window 2222 and is electrically connected to the conductive part on the circuit board 10, so that the polarity of the bottom surface of the battery 30 is reliably conducted to the circuit board 10 through the second spring 50, thereby completing the power supply path of the other pole of the battery. The terminal stub 52 can also be made of metal material with good elastic recovery properties by stamping and bending to ensure that stable contact pressure is maintained after the battery is installed and replaced multiple times.

[0040] In this invention, the number and distribution of terminal branches 52 are not limited. For example, in some embodiments, two or more terminal branches 52 can be provided, and the multiple terminal branches 52 can be distributed on the bottom wall 222 in a single row, double row or staggered manner to accommodate batteries of different sizes or polarity structures.

[0041] By increasing the number and distribution range of terminal stubs 52, the effective contact area between the second spring 50 and the bottom surface of the battery 30 can be significantly increased. Even if poor contact is caused in a local area of ​​the bottom of the battery 30 due to oxidation, rust or dirt, the terminal stubs 52 in other positions can still maintain reliable contact with the bottom surface of the battery, thereby improving the stability and reliability of the power supply connection of the entire circuit.

[0042] The presence of window 2222 provides a passage for the fixing part 58, allowing the second spring piece 50 to cross from the bottom of the battery compartment 22 into the circuit board fixing groove 27 and communicate with the circuit board 10. To further improve the elasticity and span adaptability of the second spring piece 50, an extension piece 56 can also be formed between the terminal branch 52 and the fixing part 58. The extension piece 56 can be regarded as an elastic extension section on the second spring piece 50, which increases the elastic deformation length while ensuring conductivity, so that the second spring piece 50 can better absorb assembly tolerances and battery thickness errors, ensure stable clamping force between the terminal branch 52 and the bottom surface of the battery 30, and ensure that the fixing part 58 and the circuit board 10 are in a proper contact position.

[0043] In this invention, the first spring 40 and the second spring 50 serve as conductive springs for the positive and negative electrodes of the battery 30, respectively. For example, in one specific embodiment, the first spring 40 can be used as the positive electrode spring, contacting the positive electrode side of the battery 30; and the second spring 50 can be used as the negative electrode spring, contacting the negative electrode bottom surface of the battery 30. Of course, without changing the circuit function, the polarity distribution of the two can be appropriately adjusted according to the circuit design requirements.

[0044] In other embodiments, the remote control 100 may further include a battery cover 92 that snaps onto the opening of the battery compartment 22. The battery cover 92 may be made of plastic or metal by injection molding or stamping, and reliably engages with the housing 20 through a structure such as a snap, screw, or sliding cover. It is used to close the opening of the battery compartment 22 and limit and press the battery 30, thereby preventing the battery from coming out of the battery compartment 22 when the remote control is subjected to external impact or long-term shaking, further improving the overall safety and reliability of the device.

[0045] In addition, the remote control 100 may also include an upper shell 70 and a lower shell 60. The shell 20 and its components, including the circuit board 10, the first spring 40, the second spring 50, and the battery 30, are clamped and sealed between the upper shell 70 and the lower shell 60. The upper shell 70 and the lower shell 60 can be made of plastic or metal, and their outer surfaces can be designed with different textures, colors, or shapes according to the product positioning to enhance the overall aesthetics and grip. This shell structure not only provides mechanical strength support and protection for the internal components, but also, with appropriate sealing structures at the shell seams, can achieve a certain degree of dustproof, waterproof, or waterproof fog-proof effect, protecting the circuit board 10 and the battery 30 from external environmental influences and extending the service life of the remote control 100.

[0046] In some embodiments, a sealing gasket 80 may also be provided on the inner side of the bottom shell 60. The sealing gasket 80 is preferably made of a soft and resilient material, such as silicone, rubber, or similar elastomer material. After assembly, the sealing gasket 80 can fit against the housing 20, the circuit board 10, and related components, further preventing dust, moisture, or water mist from entering the interior from the housing seams or around the buttons, which helps to improve the overall sealing level of the device and provides a certain degree of cushioning and shock absorption for the circuit board 10.

[0047] In one embodiment, the remote control 100 may further include buttons 90, such as multiple function keys, disposed on the outer surface of the bottom housing 60. The buttons 90 may correspond to corresponding button circuits or microswitches on the circuit board 10 via soft rubber buttons, hard buttons combined with conductive rubber particles or metal conductive sheets, etc., allowing the user to perform different function operations on the controlled device by pressing different buttons 90. The shape, size, and distribution of the buttons 90 can be designed according to usage habits and ergonomic requirements, such as using button caps of different heights, different surface textures or shapes to differentiate tactile sensations, so that users can easily distinguish and operate each function key even in blind operation.

Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.

[0049] The above description is only a partial embodiment 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 principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
