Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a button battery compartment structure and a candle lamp. Background Technology

[0002] Traditional candles, as a time-honored lighting and decorative tool, possess irreplaceable ritualistic and aesthetic value in various life scenarios. However, their reliance on open flame combustion leads to significant safety hazards, including fire risks, high-temperature burns, and combustion gas emissions. Their use is particularly restricted in enclosed spaces or areas where children play. In addition, traditional candles have inherent drawbacks such as short burning time, the need for frequent replacement, and the environmental pollution caused by dripping wax.

[0003] To replace open flame candles, LED simulated candle lights have emerged. In existing technologies, LED candle lights typically use one or more LED light sources with a diffuser to simulate the flame effect, and are powered by a built-in battery or an external power source to achieve wireless / wired use.

[0004] In the power supply system design of LED simulated candle lights, the battery compartment, as the core component of the portable lighting device, directly affects product safety and user experience due to the reliability of its switching structure. Existing LED simulated candle lights generally use screw caps, sliding rails, or tool-assisted methods to lock / open the battery compartment. Conventional LED simulated candle lights use button batteries for power and are opened by manually rotating the battery cover. This structure lacks a secondary locking mechanism, and the battery cover may be dislodged due to inertia when the device is shaken. Furthermore, the opening torque of the battery cover in this method is low, below the torque threshold of a child's fingers, and can be opened by hand, posing a risk of accidentally swallowing the button battery and exposing the electrodes.

[0005] Therefore, this application aims to propose a button battery compartment structure and a candle lamp that requires two-handed operation and has a secondary locking mechanism. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model proposes a button battery compartment structure and a candle lamp to solve the above-mentioned technical problems.

[0007] According to a first aspect of the present invention, a button battery compartment structure is provided, including a base and a battery cover. The base has a battery compartment for accommodating a battery. The battery compartment has a guide groove, through which the battery cover can be switched between a locked position and an unlocked position. An elastic buckle for unlocking the battery cover is provided on a part of the battery compartment outside the guide groove.

[0008] By adopting the above technical solution, when the battery is placed in the battery compartment, the battery cover is pushed from the unlocking position to the locking position along the guide groove to lock it. When it is necessary to unlock the battery cover, the user needs to press the elastic buckle with one hand to unlock the battery cover, while the other hand pushes the battery cover along the guide groove to rotate in the unlocking direction, so as to realize the function of unlocking the battery cover with both hands. This can effectively avoid the safety hazards caused by children accidentally opening the battery cover.

[0009] Preferably, the base has a locking opening corresponding to the position of the elastic buckle, and the edge of the battery cover has a locking arm, the end of which engages with the locking opening at the locking position.

[0010] By adopting the above technical solution, the locking arm can slide between the locked position and the unlocked position along the guide groove. When the locking arm moves to the locked position, its end is locked into the locking hole. When unlocking is required, the user presses the elastic buckle with one hand, and the elastic buckle pushes the first locking arm out of the locking hole. At the same time, the other hand pushes the battery cover in the unlocking direction to complete the unlocking operation.

[0011] More preferably, the bottom surface of the battery cover is further provided with a force-applying module for pushing the battery cover to rotate, and the force-applying module is located on the side away from the locking port.

[0012] By adopting the above technical solution, the elastic buckle and the force application module form a left-right opposite structure at the bottom of the battery compartment. When unlocking is required, the user presses the elastic buckle with the left hand and pushes the force application module in the unlocking direction with the right hand. Only when the left and right hands move in sync can the battery cover be unlocked.

[0013] More preferably, the locking arm includes a first locking arm and a second locking arm symmetrically distributed on both sides of the battery cover, the force application module is located on the connecting line of the first locking arm and the second locking arm, and the force application module is located near the second locking arm.

[0014] By adopting the above technical solution, the first locking arm and the second locking arm are subjected to more balanced forces when moving in the corresponding guide groove. The lengths of the first locking arm and the second locking arm may not be equal. When there is a length difference between the first locking arm and the second locking arm, they can form a directional installation structure when they cooperate with the corresponding guide groove, which can avoid the misalignment problem caused by the locking arm and the guide groove not matching during the installation process.

[0015] More preferably, the battery cover has movable notches on both sides of the first locking arm, and the end of the first locking arm protrudes to form a snap-fit ​​portion that cooperates with the locking port, and the thickness of the snap-fit ​​portion gradually decreases along the extension direction of the guide groove.

[0016] By adopting the above technical solution, the setting of the movable notch creates a certain gap between the two sides of the first locking arm and the battery cover, and the first locking arm is connected to the battery cover at only one end, forming a cantilever structure. This gives the first locking arm a certain elastic deformation capability. The shape and size of the latching part make it similar to a right-angled bevel, making it easier for the first locking arm to slide along the guide groove to the locking position. The first locking arm will naturally spring up due to the elastic force, and the latching part will simultaneously engage in the locking hole. It is also easier to unlock the latching part using the elastic buckle.

[0017] More preferably, one inner surface of the locking opening is connected to one end of the elastic buckle, and the elastic buckle forms a triangular inclined protrusion outward from the locking opening, with the inclined surface of the elastic buckle located on the side away from the battery compartment.

[0018] By adopting the above technical solution, the elastic buckle also has a cantilever structure similar to the first locking arm, making it easier for the user to press it to produce elastic deformation. This allows it to press against the latching part and push it out of the locking slot, thus disengaging the first locking arm from the locking slot. The inclined boss structure of the elastic buckle is more suitable for the user's fingers to press the elastic buckle from the outside of the base, which is more in line with operating habits.

[0019] More preferably, the guide groove extends circumferentially from the unlock position to the locking position and gradually approaches the inner top surface of the battery compartment, and the guide groove includes a first guide groove and a second guide groove corresponding to the first locking arm and the second locking arm, respectively, and the locking port is located at the locking position of the first guide groove.

[0020] By adopting the above technical solution, the sliding stroke of the first guide groove and the second guide groove is ensured to be the same, and the first guide groove and the second guide groove gradually approach the inner top surface of the battery compartment from the unlock position to the locking position, so that the first guide groove and the second guide groove have a stepped undulating structure. During the locking process, the part of the battery cover that cooperates with the first guide groove and the second guide groove will be squeezed and deformed, thereby having a certain squeezing and anti-loosening effect.

[0021] More preferably, the bottom surface of the base has at least two downwardly protruding columnar legs, the end faces of the columnar legs and the apex of the elastic buckle are located on the same horizontal plane.

[0022] By adopting the above technical solution, the apex of the columnar support leg and the elastic buckle can provide multi-point support for the base, which not only ensures stable support for the base, but also avoids the bottom surface of the base from making complete contact with the surface on which it is placed, thus preventing wear and tear on important components such as the battery cover due to long-term contact.

[0023] Preferably, the top surface of the battery cover is provided with a protruding clamping component, which includes a clamping ring and a clamping post located at the center of the clamping ring, with the center of the top surface of the battery cover as the center.

[0024] By adopting the above technical solution, while the battery cover is locked to the battery compartment, the clamping ring and clamping column can provide a stable support force to the bottom surface of the battery. In conjunction with the structure of the first guide groove and the second guide groove gradually approaching the top surface of the battery compartment, the battery is effectively and firmly pressed against the battery compartment, avoiding displacement or poor contact of the battery due to shaking or vibration.

[0025] According to a second aspect of the present invention, a candle lamp is provided, comprising a button battery compartment structure as described in any of the preceding claims, and further comprising a housing, a switch, and a lamp bead. The housing is fitted onto a base, and the lamp bead has a first pin and a second pin. The first pin passes through the top of the battery compartment and connects to the battery. The base has a switch window on one side of the battery compartment, and the switch is slidably disposed above the switch window. The battery compartment has a connection port on the side near the switch window, and the first pin passes through the top of the switch and enters the connection port. The switch drives the second pin to connect or disconnect from the side of the battery.

[0026] By adopting the above technical solution, the first and second pins of the LED bead enter from the top and side of the battery compartment, respectively, and connect to the top and side of the battery. The user can use a sliding switch to connect or disconnect the second pin from the side of the battery to control the circuit. The LED bead installation, circuit connection and switch control are integrated into a compact space, ensuring conductivity while improving the matching accuracy and stability of the candle lamp.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] The button battery compartment structure and candle lamp proposed in this utility model effectively solve the problems of unreliable battery compartment locking, easy accidental opening by children, and insufficient circuit connection stability in the prior art. In the button battery compartment structure, the base and battery cover are connected by a first guide groove and a second guide groove, together with a first locking arm and a second locking arm, to form a sliding and rotating connection. The locking port at the locking position of the first guide groove and the setting of the elastic buckle constitute a secondary locking mechanism. It is necessary to operate the elastic buckle with both hands and push the force application module to unlock, which significantly improves the anti-accidental opening effect. The movable notches on both sides of the first locking arm form a cantilever elastic structure, which, together with the snap-fit ​​part, allows it to naturally spring into the locking port when locked. The locking arm and the positioning notch with corresponding size form a guiding installation structure to avoid misalignment and ensure locking reliability. Attached Figure Description

Detailed Implementation

[0041] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0042] According to the first aspect of this application, a button battery compartment structure is proposed. Figure 1 An exploded view of a button battery compartment structure according to an embodiment of the present invention is shown, as follows: Figure 1As shown, the button battery compartment structure includes a base 01 and a battery cover 02. The base 01 has an upwardly protruding cylindrical battery compartment 03. The side wall of the battery compartment 03 has a first guide groove 04 and a second guide groove 05 extending in the same circumferential direction (circumferential direction from the unlocked position to the locked position). The top edge of the battery cover 02 has a first locking arm 06 and a second locking arm 07 extending radially. The base 01 has a locking opening 08 corresponding to the locking position of the first guide groove 04, and the locking opening 08 has an elastic buckle 09. The bottom surface of the battery cover 02 has a position corresponding to the second locking arm 07 for pushing the battery cover 02 to rotate. The force application module 10 is located on the side away from the locking port 08, and the line connecting the force application module 10 and the locking port 08 passes through the radial center of the battery cover 02. The bottom surface of the base 01 is provided with positioning notches at the unlocking positions of the first guide groove 04 and the second guide groove 05. The positioning notches include a first positioning notch 11 and a second positioning notch 12 corresponding to the first guide groove 04 and the second guide groove 05, respectively. The first locking arm 06 and the second locking arm 07 slide into the first guide groove 04 and the second guide groove 05 from the first positioning notch 11 and the second positioning notch 12, and the end of the first locking arm 06 is engaged in the locking port 08.

[0043] Specifically, when the battery 28 is placed into the battery compartment 03, the first locking arm 06 and the second locking arm 07 of the battery cover 02 are slid from the positions of the first positioning notch 11 and the second positioning notch 12 to the locking positions of the first guide groove 04 and the second guide groove 05, respectively. This causes the end of the first locking arm 06 to engage in the locking port 08, forming a secondary lock. When it is necessary to unlock the battery cover 02, the user needs to press the elastic buckle 09 with one hand to disengage the first locking arm 06 from the locking port 08, while the other hand pushes the force application module 10 in the unlocking direction, causing the battery cover 02 to rotate in the unlocking direction. This achieves the function of unlocking the battery cover 02 with both hands. The secondary locking structure can effectively avoid the safety hazards caused by children accidentally opening the battery cover 02.

[0044] Specifically, Figure 1 The bottom surface of the base 01 has at least two downward-protruding columnar legs 13. The end face of the columnar legs 13 and the vertex of the elastic buckle 09 are located on the same horizontal plane. As the main component supporting the candle lamp, the bottom surface of the base 01 needs to be in contact with the placement surface for a long time. During the process of moving the candle lamp, some important parts (such as the battery cover 02) located at the bottom of the base 01 may be worn. In this embodiment, there are two columnar legs 13, and the three points connecting the ends of the two columnar legs 13 and the vertex of the elastic buckle 09 form a triangular structure to provide stable support for the base 01 and prevent its bottom surface from being in complete contact with the placement surface.

[0045] Furthermore, the inner surface of the locking port 08 near the base 01 is connected to one end of the elastic buckle 09, and the elastic buckle 09 forms an inverted triangular inclined boss downwards. The inclined surface of the elastic buckle 09 is located on the side away from the first guide groove 04. The inclined surface of the elastic buckle 09 and the bottom surface of the force application module 10 are provided with several raised anti-slip textures to increase the friction between the user's hand and the elastic buckle 09 and the force application module 10. The elastic buckle 09 also has a cantilever structure similar to the first locking arm 06, which makes it easier for the user to press it to produce elastic deformation, thereby abutting against the end of the first locking arm 06 and pushing it out of the locking port 08, so that the two are disengaged. The inclined boss structure of the elastic buckle 09 is more suitable for the user's operating habit of pressing the elastic buckle 09 from the outside of the base 01.

[0046] Figure 2 A perspective view of the bottom surface of the base according to a specific embodiment of the present invention is shown, as follows: Figure 1-2 As shown, the first guide groove 04 and the second guide groove 05 are symmetrically distributed with the axis of the battery compartment 03 as the center of symmetry. From the bottom view of the base 01, both the first guide groove 04 and the second guide groove 05 extend in a clockwise direction (circumferential direction from the unlocking position to the locking position). They can also extend counterclockwise. In order to conform to the conventional rotation unlocking habit, clockwise extension is adopted in this embodiment. Therefore, the first locking arm 06 and the second locking arm 07 of the battery cover 02 can perform clockwise locking and counterclockwise unlocking actions along the first guide groove 04 and the second guide groove 05, respectively. Specifically, the first positioning notch 11 is directly opposite the second positioning notch 1. 2. The sliding strokes of the first locking arm 06 and the second locking arm 07 are the same, and the first guide groove 04 and the second guide groove 05 gradually approach the inner top surface of the battery compartment 03 along the circumferential direction from the unlock position to the locking position, so that the first guide groove 04 and the second guide groove 05 have a stepped undulating structure. During the locking process, the first locking arm 06 and the second locking arm 07 will be squeezed and deformed, thus having a certain squeezing and anti-disengagement effect. When the first locking arm 06 moves to the locking port 08, it will lose the squeezing force of the first guide groove 04, so it can naturally bounce up and lock into the locking port 08 to achieve secondary locking.

[0047] Preferably, the upper inner side of the battery compartment 03 tapers towards the axis to form a support platform 14. Figure 2The bottom view of the base 01 is shown, so the support platform 14 is located at the bottom of the figure. The support platform 14 is located in the circumferential range outside the first guide groove 04 and the second guide groove 05. Specifically, there is a gap between the table surface of the support platform 14 and the bottom surface of the base 01. This gap is adapted to the thickness of the battery cover 02. When the battery cover 02 is rotated and locked on the battery compartment 03, the top surface of the battery cover 02 will fit against the table surface of the support platform 14, limiting the distance between the top surface of the battery cover 02 and the inner top surface of the battery compartment 03, thereby ensuring that the battery 28 in the battery compartment 03 will not be excessively squeezed.

[0048] Figure 3 A schematic diagram of the top and bottom surfaces of the battery cover according to a specific embodiment of the present invention is shown, as follows: Figure 1-3 As shown in the figure, the left side of the diagram shows the top surface structure of the battery cover 02, and the right side shows the bottom surface structure of the battery cover 02. The battery cover 02 has movable notches 15 on both sides of the first locking arm 06. These notches 15 create a certain gap between the two sides of the first locking arm 06 and the battery cover 02. Only one end of the first locking arm 06 is connected to the battery cover 02, forming a cantilever structure. This allows the first locking arm 06 to have a certain elastic deformation capability. The bottom surface of the end of the first locking arm 06 protrudes downwards to form a latching part 16. The thickness of 16 gradually decreases along the extension direction of the first guide groove 04. In this embodiment, a portion of the top right side of the latching part 16 is a flat surface, and the left side is a slope. The size of the latching part 16 makes it resemble a right-angled bevel, making it easier for the first locking arm 06 to slide along the first guide groove 04 to the locking position. The first locking arm 06 will naturally spring up due to the elastic force, and the latching part 16 will simultaneously engage in the locking port 08. A mechanical locking sound will be generated during the process of the latching part 16 engaging in the locking port 08, indicating to the user that it has been locked in place.

[0049] Preferably, the first locking arm 06 and the second locking arm 07 are located in the same radial direction of the battery cover 02, so that the battery cover 02 is subjected to more balanced force during installation. The first locking arm 06 and the second locking arm 07 extend in opposite directions, the length of the first locking arm 06 is greater than the length of the second locking arm 07, and the size of the first positioning notch 11 is greater than the size of the second positioning notch 12. The difference in length between the first locking arm 06 and the second locking arm 07 corresponds to the difference in size between the first positioning notch 11 and the second positioning notch 12, forming a guiding installation structure that can avoid misalignment caused by the locking arm and the positioning notch not matching during installation.

[0050] Preferably, the top surface of the battery cover 02 is provided with a protruding clamping component. The clamping component includes a clamping ring 17 and a clamping post 18 located at the center of the clamping ring 17. The clamping ring 17 is centered on the center of the top surface of the battery cover 02. While the battery cover 02 is locked to the battery compartment 03, the clamping ring 17 and the clamping post 18 can provide a stable support force to the bottom surface of the battery 28. With the structure of the first guide groove 04 and the second guide groove 05 gradually approaching the top surface of the battery compartment 03, the battery 28 is firmly pressed against the battery compartment 03, preventing the battery 28 from being displaced or having poor contact due to shaking or vibration.

[0051] Figure 4 A schematic diagram of a battery cover locking according to a specific embodiment of the present invention is shown, such as... Figure 1-4 As shown, when the battery cover 02 is locked in place, the first locking arm 06 and the second locking arm 07 are respectively located in the locked positions of the first guide groove 04 and the second guide groove 05, and the latching part 16 at the end of the first locking arm 06 slides from the first guide groove 04 into the locking port 08 for locking. When unlocking is required, the elastic buckle 09 needs to be operated first to push the latching part 16 out of the locking port 08. At this time, the force application module 10 needs to be pushed simultaneously to rotate the battery cover 02 in the unlocking direction. If the force application module 10 is not operated at the same time and the elastic buckle 09 is not released, the latching part 16 will spring back with the first locking arm 06 and re-lock into the locking port 08 to maintain the lock.

[0052] According to a second aspect of this utility model, a candle lamp is provided, comprising a button battery compartment structure as described in any of the preceding claims. Figure 5 An explosion diagram of a candle lamp according to an embodiment of the present invention is shown, as follows: Figure 1-5 As shown, the candle lamp also includes a housing 19, a switch 20, a battery 28, and an LED 21. The battery 28 is housed in a battery compartment 03. The housing 19 is fitted onto the base 01 from top to bottom. The LED 21 has a first pin 22 and a second pin 23. The first pin 22 passes vertically through the top of the battery compartment 03 and is bent to fit against the inner top surface of the battery compartment 03. The base 01 has a switch window 24 through which the bottom of the switch 20 passes. The top surface of the switch window 24 protrudes to form a sliding seat 25 that slides with the middle of the switch 20. The battery compartment 03 has a connection port 26 on the side near the sliding seat 25. The top of the switch 20 bends toward the connection port 26 to form a connection part 27. The second pin 23 passes vertically through the connection part 27 into the battery compartment 03. The connection part 27 causes the second pin 23 to contact or separate from the side of the battery 28.

[0053] Figure 6 A schematic diagram of a switch installation according to a specific embodiment of the present invention is shown. Figure 7 A cross-sectional schematic diagram of a candle lamp assembled according to a specific embodiment of the present invention is shown, as follows: Figure 1-7As shown, the middle part of the switch 20 has a sliding part 30, and a handle 29 extends from the bottom surface of the sliding part 30. The connecting part 27 bends from the top of the sliding part 30 toward the connecting port 26. Specifically, the sliding part 30 is slidably mounted on the sliding seat 25, and the handle 29 extends downward from the switch window 24 to the outside of the base 01. When the sliding part 30 slides on the sliding seat 25, the flange 31 slides with the sliding part 30. The flange 31 reciprocates to engage / disengage with the locking post 32, and a mechanical locking sound is emitted during the engagement / disengagement process, similar to the sound of the electrical switch 20, which can simulate the locking effect of a real electrical switch 20.

[0054] Specifically, the connecting part 27 is provided with a through hole adapted to the size of the second pin 23. After the second pin 23 passes through the through hole, it enters the battery compartment 03 from the connecting port 26. When the switch 20 slides, the connecting part 27 drives the first pin 22 to move along the tangent direction of the battery 28. When the second pin 23 is at the tangent point, the positive and negative terminals of the battery 28 and the lamp bead 21 are connected, and the lamp bead 21 lights up. When the second pin 23 moves away from the tangent point, the two are disconnected, and the lamp bead 21 turns off.

[0055] Furthermore, the inner top surface of the battery compartment 03 is also provided with a lamp bead holder 33 for placing the lamp bead 21, and the top of the battery compartment 03 is provided with a through hole within the range of the lamp bead holder 33 for the first pin 22 to pass through. After the first pin 22 passes through the through hole, it is attached to the inner top surface of the battery compartment 03 and connected to the top surface of the battery 28.

[0056] Figure 8 Schematic diagrams of three housing 19 shapes according to specific embodiments of the present invention are shown, such as... Figure 1-8 As shown in the figure, the shells 19 shown in A and C are designed based on the shape of a real candle. The difference between the two is that the shells 19 are different in height (C is higher than A). They are often used in scenarios such as prayer. The shell 19 shown in B is the shortest of the three shapes. B has added a Möbius stripe to the top of the shell 19, which is more stylish than the regular candle shape and is more suitable for entertainment scenarios.

[0057] Furthermore, the top of the housing 19 is also provided with a flame-shaped lamp bead cover 34. When the housing 19 is fitted onto the base 01, the lamp bead cover 34 covers the lamp bead 21, making the light emitted by the lamp bead 21 more closely resemble a real candle flame.

[0058] Figure 9 A schematic diagram of the bottom structure of the housing according to a specific embodiment of this application is shown, as follows. Figure 1-9As shown, the bottom inner edge of the housing 19 is provided with an inwardly protruding positioning part 35 and an annular fixing groove 36. The outer edge of the base 01 is provided with a notch corresponding to the positioning part 35. During the installation of the housing 19, the positioning part 35 and the notch cooperate to achieve accurate positioning, and then the fixing groove 36 locks the edge of the base 01, making the fit between the base 01 and the housing 19 more stable and precise.

[0059] The button battery compartment structure and candle lamp proposed in this utility model effectively solve the problems of unreliable locking of the battery compartment 03, easy accidental opening by children, and insufficient stability of circuit connection in the prior art. In the button battery compartment structure, the base 01 and the battery cover 02 are connected by the first guide groove 04 and the second guide groove 05, and the first locking arm 06 and the second locking arm 07 to form a sliding and rotating connection. The locking port 08 at the locking position of the first guide groove 04 and the setting of the elastic buckle 09 constitute a secondary locking mechanism. It is necessary to operate the elastic buckle 09 with both hands and push the force application module 10 to unlock, which significantly improves the anti-accidental opening effect. The movable notches 15 on both sides of the first locking arm 06 form a cantilever elastic structure, which, together with the snap-fit ​​part 16, allows it to naturally spring into the locking port 08 when locked. The locking arm with the corresponding size and the positioning notch form a guiding installation structure to avoid misalignment and ensure locking reliability. The inner support platform 14 of the battery compartment 03 cooperates with the pressing ring 17 and pressing post 18 on the top surface of the battery cover 02 to evenly press against the battery 28 when locked, preventing shaking displacement and poor contact.
