Description

Technical Field

[0001] This application relates to the field of handheld transmitters, and more particularly to a handheld transmitter with an easily removable and waterproof battery compartment. Background Technology

[0002] Handheld transmitters are widely used in various remote control devices, and they are usually powered by built-in batteries. To facilitate battery replacement, most existing handheld transmitters use a separate battery cover structure. That is, a mounting slot is opened in the transmitter housing, the battery body is placed in the mounting slot, and then the mounting slot is closed by the battery cover.

[0003] However, due to manufacturing tolerances and assembly errors, a complete seal between the battery cover and the mounting slot is difficult to achieve, and minor gaps inevitably exist between them. In outdoor operations, rainy weather, or when hands are wet, moisture can easily seep into the battery compartment through these gaps. This seeping water will directly contact the battery contacts at the front of the battery body and the conductive contacts at the interface with the device body, creating a conductive path and causing a short circuit. A short circuit not only causes abnormal heating or even damage to the battery body but may also burn out the conductive components within the interface, resulting in a power outage and severely affecting the normal operation of the handheld transmitter. Summary of the Invention

[0004] To facilitate the installation and removal of the battery body and improve the waterproof performance of the battery compartment, this application provides a handheld transmitter with an easily detachable and waterproof battery compartment.

[0005] This application provides a handheld transmitter with an easily detachable and waterproof battery compartment, employing the following technical solution: A handheld transmitter with an easily detachable and waterproof battery compartment includes: Transmitter housing; A mounting slot is provided on the transmitter housing, and a docking interface is provided at the front end of the mounting slot, with conductive contacts inside the docking interface; The battery body is housed in the mounting slot, and the front end of the battery body is provided with battery contacts, which are in contact with conductive contacts. A sealing ring is provided between the battery body and the connector; A pusher assembly is disposed on the transmitter housing and applies a forward pusher force to the battery body; A water inlet trough is located at the rear end of the mounting trough and extends to the outer wall of the transmitter housing; Specifically, taking the battery body insertion direction as a reference, the direction towards the docking interface is considered front, and the direction away from the docking interface is considered rear.

[0006] Optionally, the pushing component includes: A rotating frame is hinged in the mounting slot; A card slot is provided at the rear end of the mounting slot; A buckle is provided on the rotating frame and engages with the slot.

[0007] Optionally, the mounting slot has connecting slots on the left and right sides, and the rotating frame has rotating heads on the left and right sides. The rotating frame is hinged to the connecting slots through the rotating heads.

[0008] Optional, also includes: Two front cam support legs are rotatably connected to the transmitter housing and are located on the front side of the rotating head; Two rear cam support legs are rotatably connected to the transmitter housing and located on the rear side of the rotating head; The flange end of the front cam support leg is oriented in the opposite direction to the flange end of the rear cam support leg, and the flange ends of both the front cam support leg and the rear cam support leg can selectively extend out of the bottom of the transmitter housing. A drive mechanism is used to drive the front cam support leg and the rear cam support leg to rotate synchronously.

[0009] Optionally, the driving mechanism includes two sets of driving components, respectively disposed on the left and right sides of the mounting slot, each driving component including: The follower gear is coaxially fixed to the corresponding rotating head; The front drive gear is rotatably connected inside the transmitter housing and is located in front of the follower gear; The rear drive gear is rotatably connected inside the transmitter housing and is located behind the follower gear; The front cam support leg is coaxially fixed with the front drive gear, and the rear cam support leg is coaxially fixed with the rear drive gear. The follower gear, the front drive gear, and the rear drive gear on the same side are connected in a transmission manner.

[0010] Optionally, the rotating frame has a working position and an open position. The working position is when the rotating frame is fully rotated into the connecting groove and the buckle is engaged with the groove. The open position is when the rotating frame is rotated out of the connecting groove and reaches a preset angle. When the rotating frame is in the working position, the flange end of the front cam support leg is set downward and the flange end of the rear cam support leg is set upward. When the rotating frame is in the open position, the flange end of the rear cam support leg is set downward and the flange end of the front cam support leg is set upward.

[0011] Optionally, the bottom wall of the water inlet channel is a flow-guiding slope, and the end of the flow-guiding slope near the mounting groove is an inclined upper end, and the end near the outer wall of the transmitter housing is an inclined lower end.

[0012] Optionally, the interface is stepped, and the sealing ring is disposed on the inner stepped surface of the interface and sleeved on the outside of the conductive contact.

[0013] Optionally, the push assembly further includes a groove disposed on the transmitter housing and matching the position of the latch.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the battery body within the mounting slot and applying a forward pushing force through the push assembly, the battery contacts at the front of the battery body maintain stable contact with the conductive contacts within the interface, ensuring reliable power supply. Simultaneously, the sealing ring is deformed under the pushing force, filling the gap between the battery body and the interface, forming an effective waterproof barrier to prevent external moisture from intruding into the interface from the mating point. A water channel located at the rear of the mounting slot and extending to the outer wall of the transmitter housing guides and drains any water that seeps or condenses within the mounting slot, preventing water accumulation near the interface and further reducing the risk of short circuits. This structure enables quick assembly and disassembly of the battery body, allowing for tool-free replacement, while multiple waterproofing measures enhance the lifespan and safety of the handheld transmitter in humid environments.

[0015] 2. The rotating bracket, snap-fit ​​mechanism, and slot design allow the pushing assembly to apply a continuous pushing force to the battery body securely, maintaining the compression of the sealing ring and ensuring waterproofing. Furthermore, users can easily and quickly install or remove the battery body simply by rotating the bracket.

[0016] 3. Through the arrangement of the front cam support leg, rear cam support leg, and drive mechanism, when the drive mechanism drives the front and rear cam support legs to rotate synchronously, they alternately support or release the bottom of the transmitter housing, thereby changing the inclination direction of the mounting slot bottom wall relative to the horizontal plane. This structure can automatically adjust the slope of the mounting slot bottom wall according to different states of the rotating frame. On the one hand, it forms a slope that is lower in the front and higher in the back when the battery body is installed, using gravity to assist the battery body to slide into the interface direction, reducing installation resistance; on the other hand, after the battery body is installed in place, it forms a slope that is higher in the front and lower in the back, so that the water inlet is located at the lowest point of the slope, which is conducive to the collection and drainage of accumulated water, further improving waterproof performance.

[0024] The following combination Figures 1-6 This application will be described in further detail below.

[0025] Example 1:

[0026] This application discloses a handheld transmitter with an easily detachable and waterproof battery compartment. (See also...) Figures 1-4 A handheld transmitter with an easily detachable and waterproof battery compartment includes a transmitter housing 1 and a battery body 2. The transmitter housing 1 has a mounting groove 11 on its top and a bottom groove 15 on its bottom, with multiple button slots 151 within the bottom groove 15. A connector 12 is fixed to the inner wall of the front end of the mounting groove 11, and the connector 12 contains conductive contacts 121. The battery body 2 is housed within the mounting groove 11, and a battery contact 21 is fixed to the front end of the battery body 2, contacting the conductive contacts 121. The direction towards the connector 12 is considered "front," and the direction away from the connector 12 is considered "rear."

[0027] Reference Figure 1To improve the waterproof performance of the battery compartment, a sealing ring 3 is provided between the battery body 2 and the interface 12. The interface 12 is stepped, and the sealing ring 3 is fixed to the inner stepped surface of the interface 12 and is fitted over the conductive contact 121. Furthermore, the transmitter housing 1 is provided with a pushing assembly 4, which applies a forward pushing force to the battery body 2. After the battery body 2 is installed in the mounting slot 11, the forward pushing force applied by the pushing assembly 4 ensures stable contact between the battery contact 21 at the front end of the battery body 2 and the conductive contact 121 inside the interface 12, ensuring reliable power supply. Simultaneously, the sealing ring 3 is deformed under the pushing force, filling the gap between the battery body 2 and the interface 12, forming an annular seal around the battery contact 21 and the conductive contact 121, creating an effective waterproof barrier. This prevents external moisture from entering the conductive contact area inside the interface 12 from the outside, reducing the risk of poor contact or short circuit due to water ingress.

[0028] Reference Figures 3-5 The push assembly 4 includes a rotating frame 41, a slot 42, and a buckle 43. Connecting slots 13 are provided on the left and right sides of the mounting slot 11. Rotating heads 411 are integrally formed on the left and right sides of the rotating frame 41, and the rotating frame 41 is hinged to the connecting slots 13 via the rotating heads 411. The slot 42 is located at the rear end of the mounting slot 11, and the buckle 43 is integrally formed on the rotating frame 41 and engages with the slot 42. Users can easily install or remove the battery body 2 by simply moving the rotating frame 41; the operation is simple and quick. The engaging structure of the buckle 43 and the slot 42 provides reliable locking force, preventing the rotating frame 41 from accidentally loosening during use, ensuring the continuity and stability of the pushing force, thereby maintaining the compression state of the sealing ring 3 and ensuring waterproofing.

[0029] Reference Figure 3 , Figure 4 and Figure 6The rotating frame 41 has a working position and an open position. The working position is when the rotating frame 41 is fully rotated into the connecting groove 13 and the buckle 43 is engaged with the groove 42. The open position is when the rotating frame 41 is rotated out of the connecting groove 13 and reaches a preset angle. In this embodiment, the preset angle of the open position is 90°. To facilitate the installation of the battery body 2, the rotating frame 41 is provided with a guide slope 412 for abutting the rear end of the battery body 2. During the rotation of the rotating frame 41 from the open position to the working position, the guide slope 412 first contacts the rear end of the battery body 2. As the rotating frame 41 continues to rotate, the guide slope 412 gradually pushes the battery body 2 forward, so that it smoothly slides into the front end of the mounting groove 11 and aligns with the interface 12. The guide slope 412 applies a progressive pushing force to the battery body 2, avoiding the deviation or jamming of the battery body 2 due to sudden force, ensuring the smoothness of the installation process, and also reducing the impact on the battery body 2 and the sealing ring 3. To facilitate the removal of the battery body 2, the push assembly 4 also includes a groove 44, which is formed on the transmitter housing 1 and matches the position of the latch 43. Thus, when it is necessary to remove the battery body 2, the user can easily access the latch 43 through the groove 44 and push it away from the slot 42 without having to use fingernails or tools to forcibly pry it open, thus avoiding breakage of the latch 43 or scratches on the housing due to inconvenient operation.

[0030] Reference Figure 4 and Figure 6 To further improve waterproofing, a water-guiding channel 14 is provided at the rear end of the mounting groove 11, and the water-guiding channel 14 extends to the outer wall of the transmitter housing 1. To facilitate the drainage of water that has seeped or condensed in the mounting groove 11 and prevent water from stagnating near the interface 12, thereby further reducing the risk of short circuit, the bottom wall of the water-guiding channel 14 is a drainage slope, with the end of the drainage slope near the mounting groove 11 being an inclined upper end and the end near the outer wall of the transmitter housing 1 being an inclined lower end.

[0031] Reference Figure 1 and Figure 3The handheld transmitter also includes two front cam legs 5 and two rear cam legs 6. The two front cam legs 5 are rotatably connected to the left and right sides of the transmitter housing 1 and are symmetrically arranged, located in front of the rotating head 411. The two rear cam legs 6 are rotatably connected to the transmitter housing 1 and are symmetrically arranged, located in front of the rotating head 411. The flange ends of the front cam legs 5 and the rear cam legs 6 face opposite directions, and both flange ends can selectively extend out of the bottom of the transmitter housing 1. When the rotating frame 41 is in the working position, the flange ends of the front cam legs 5 face downwards, and the flange ends of the rear cam legs 6 face upwards. When the rotating frame 41 is in the open position, the flange ends of the rear cam legs 6 face downwards, and the flange ends of the front cam legs 5 face upwards. Thus, when the rotating frame 41 is in the working position, the flange end of the front cam support leg 5 faces downward and the flange end of the rear cam support leg 6 faces upward, so that the bottom wall of the mounting groove 11 forms a slope that is higher in the front and lower in the back, which is conducive to the flow of accumulated water towards the water inlet 14; when the rotating frame 41 is in the open position, the flange end of the rear cam support leg 6 faces downward and the flange end of the front cam support leg 5 faces upward, so that the bottom wall of the mounting groove 11 forms a slope that is lower in the front and higher in the back, which is convenient for the battery body 2 to slide into the interface 12 by gravity.

[0032] Reference Figure 3 and Figure 5 The handheld transmitter also includes a drive mechanism for synchronously rotating the front cam support leg 5 and the rear cam support leg 6. The drive mechanism includes two sets of drive components 7, which are respectively located on the left and right sides of the mounting groove 11. Each drive component 7 includes a follower gear 71, a front transmission gear 72, and a rear transmission gear 73. The front transmission gear 72 and the rear transmission gear 73 have the same diameter, and the diameter of the follower gear 71 is larger than the diameters of the front transmission gear 72 and the rear transmission gear 73. The follower gear 71 is located inside the transmitter housing 1 and is coaxially fixed to the corresponding rotating head 411. The front transmission gear 72 is rotatably connected inside the transmitter housing 1 and is located in front of the follower gear 71. The rear transmission gear 73 is rotatably connected inside the transmitter housing 1 and is located behind the follower gear 71. The front cam support leg 5 is coaxially fixed to the front transmission gear 72, and the rear cam support leg 6 is coaxially fixed to the rear transmission gear 73. The follower gear 71, the front transmission gear 72, and the rear transmission gear 73 on the same side are connected by a transmission component 74. In this embodiment, specifically, the transmission ratio of the follower gear 71 to the front drive gear 72 / rear drive gear 73 is 1:2, so that when the rotating frame 41 rotates 90°, the front drive gear 72 and the rear drive gear 73 rotate synchronously 180°, thereby driving the flange ends of the front cam support leg 5 and the rear cam support leg 6 to flip in the opposite direction.

[0033] When the drive mechanism drives the front cam support leg 5 and the rear cam support leg 6 to rotate synchronously, they alternately support or release the bottom of the transmitter housing 1, thereby changing the inclination direction of the bottom wall of the mounting groove 11 relative to the horizontal plane. This structure can automatically adjust the slope of the bottom wall of the mounting groove 11 according to different states of the rotating frame 41. On the one hand, when the battery body 2 is installed, a slope with a lower front and a higher back is formed, using gravity to assist the battery body 2 to slide into the interface 12, reducing installation resistance. On the other hand, after the battery body 2 is installed in place, a slope with a higher front and a lower back is formed, so that the water inlet trough 14 is located at the lowest point of the slope, which is conducive to the collection and drainage of accumulated water, further improving waterproof performance. In addition, the drive mechanism does not require an additional drive source, relying entirely on the mechanical linkage when the rotating frame 41 rotates, thereby saving manufacturing costs and energy consumption, while also ensuring the reliability of the slope switching of the mounting groove 11.

[0034] Reference Figure 3 and Figure 5 The transmission assembly 74 includes an intermediate gear 741 and a transmission bar 742. The intermediate gear 741 is rotatably disposed within the launcher housing 1, and the transmission bar 742 is slidably connected within the launcher housing 1 along the front-rear direction. The intermediate gear 741 is located below the follower gear 71 and the two mesh with each other. The transmission bar 742 is located below the intermediate gear 741 and above the front transmission gear 72 and the rear transmission gear 73. An upper tooth surface 7421 is fixed to the upper end of the transmission bar 742 and meshes with the intermediate gear 741. Lower tooth surfaces 7422 are fixed on both sides of the lower end of the transmission bar 742. One lower tooth surface 7422 meshes with the front transmission gear 72, and the other lower tooth surface 7422 meshes with the rear transmission gear 73.

[0035] When the rotating frame 41 is rotated, it drives the rotating head 411 to rotate. When the rotating head 411 rotates, it drives the follower gear 71 to rotate. When the follower gear 71 rotates, it drives the intermediate gear 741 to rotate. When the intermediate gear 741 rotates, it drives the transmission bar 742 to slide along the front and rear direction of the transmitter housing 1. When the transmission bar 742 slides, its two lower tooth surfaces 7422 at the lower end drive the front transmission gear 72 and the rear transmission gear 73 to rotate synchronously in opposite directions. The front transmission gear 72 drives the front cam support leg 5, which is fixed to it on the same axis, to rotate. The rear transmission gear 73 drives the rear cam support leg 6, which is fixed to it on the same axis, to rotate, thereby realizing the synchronous rotation of the front cam support leg 5 and the rear cam support leg 6.

[0036] The implementation principle of a handheld transmitter with an easily detachable and waterproof battery compartment according to an embodiment of this application is as follows: When installing the battery body 2, the rotating frame 41 is first rotated outward around the rotating head 411 out of the connecting groove 13 to the open position. At this time, the flange end of the rear cam support leg 6 extends downward and out of the bottom of the transmitter housing 1, and the flange end of the front cam support leg 5 faces upward. The bottom wall of the mounting groove 11 forms an inclined surface that gradually slopes downward from back to front. The battery body 2 is inserted into the inner side of the rotating frame 41 and placed into the mounting groove 11 along the inclined surface. Under the assistance of gravity, the battery body 2 naturally slides towards the interface 12, and the front end of the battery body 2 can be aligned with the interface 12 without additional lifting force. Subsequently, the battery contact 21 is inserted into the interface 12 and contacts the conductive contact 121, and the sealing ring 3 is initially compressed. Next, the rotating frame 41 is rotated around the rotating head 411 into the connecting groove 13 to the working position. The rotating frame 41 is fully rotated into the connecting groove 13, and the buckle 43 engages and locks with the slot 42. The rotating frame 41 abuts against the rear end of the battery body 2 and applies a continuous pushing force, causing the sealing ring 3 to further deform and fill the gap between the battery body 2 and the interface 12, achieving a reliable seal. At the same time, the rotation of the rotating frame 41 drives the rotating head 411 to rotate, and the follower gear 71 on the rotating head 411 rotates accordingly. Through the transmission assembly 74, it drives the front transmission gear 72 and the rear transmission gear 73 to rotate synchronously in opposite directions, so that the flange end of the front cam support leg 5 turns downward and extends out of the bottom of the transmitter housing 1, and the flange end of the rear cam support leg 6 turns upward. The bottom wall of the mounting groove 11 switches to an inclined surface that gradually slopes downward from front to back, and the water inlet trough 14 is located at the lowest point of the inclined surface. When it is necessary to remove the battery body 2, the operation is reversed.

[0037] By applying a continuous pushing force to the battery body 2 through the pushing assembly 4, stable contact between the battery contact 21 and the conductive contact 121 is ensured, guaranteeing power supply reliability. Simultaneously, the sealing ring 3 undergoes sufficient deformation under axial pressure, blocking external moisture from entering through the mating position and improving waterproofing performance. The water channel 14 guides water that accidentally seeps into or condenses in the mounting groove 11 to the outer wall of the transmitter housing 1, preventing water from accumulating near the interface 12 and further reducing the risk of short circuits. The drive mechanism drives the front cam support leg 5 and the rear cam support leg 6 to rotate synchronously, achieving adaptive switching of the slope of the bottom wall of the mounting groove 11. During battery body 2 installation, a slope with a lower front and higher rear is formed, using gravity to assist the battery body 2 in sliding in, reducing installation resistance and wear. After the battery body 2 is installed in place, a slope with a higher front and lower rear is formed, placing the water channel 14 at the lowest point, facilitating the collection and drainage of accumulated water. The entire process allows for quick assembly and disassembly of the battery body 2 without the need for tools, making it easy to operate. At the same time, the combined use of multiple waterproofing methods improves the lifespan and reliability of the handheld transmitter in harsh environments such as humidity and rain.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
