Description

Technical Field

[0001] This invention relates to the field of electronic price tag technology, and more particularly to a price tag housing with a replaceable battery. Background Technology

[0002] The technological background of replaceable battery shelf tag housings primarily stems from the demands of modern retail environments for flexibility, maintainability, and cost control in electronic shelf tags. Traditional electronic shelf tags mostly use non-removable batteries. While these are small and have low power consumption, the entire shelf tag needs to be replaced when the battery reaches the end of its lifespan, increasing maintenance costs and environmental burden. To improve sustainability and reduce operating costs, designers have introduced replaceable battery housing structures, allowing battery cells to be installed and removed independently without damaging the overall casing. This technology typically involves a specialized battery compartment design inside the housing, including snap-fit, sliding rail, or magnetic fixing structures, while also ensuring waterproof, dustproof, and abrasion-resistant properties to guarantee stable electrical connections and safe use during frequent replacements. The housing material is often high-strength ABS or polycarbonate, with precision injection molding achieving a high-precision match between the battery compartment and the display module. The battery interface is usually designed with standardized contact pads or spring contacts to support quick replacement of batteries of different capacities or models.

[0003] Existing technologies, such as the invention with publication number CN109817860A, disclose an electronic price tag with a replaceable battery. This patent includes: a housing with an internal structure for housing a battery compartment; a pull-out battery compartment that can be accessed from an opening on one side of the housing into the battery compartment housing structure; the pull-out battery compartment is equipped with an elastic latch, which is compressed by the opening on one side of the housing during the process of the battery compartment entering the battery compartment housing structure; after the battery compartment is fully inside the battery compartment housing structure, the elastic latch is released and interferes with a retaining wall of the housing, while the battery compartment compresses the battery compartment ejection structure inside the housing; this application solution features a lightweight and thin structure and low cost.

[0004] During the operation and use of electronic price tag equipment, there will be situations where the lithium battery needs to be replaced regularly to ensure continuous power supply. This can lead to problems such as difficulty in removing the battery by hand due to its tight installation structure, and improper operation during replacement can easily cause poor contact of the circuit board or battery shaking, affecting the stability of the equipment and maintenance efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art: during the operation and use of electronic price tag devices, there will be situations where the lithium battery body needs to be replaced regularly to ensure continuous power supply. This leads to difficulties in removing the battery by hand due to its tight installation structure. Furthermore, improper operation during replacement can easily cause poor contact of the circuit board or battery shaking, affecting the stability of the equipment and maintenance efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a price tag housing with replaceable batteries, comprising a label shell, a frame fixedly connected to the bottom end of the label shell, a price display screen disposed on the surface of the label shell, a control frame disposed on the side of the label shell away from the price display screen, a lithium battery body installed inside the control frame, a replacement device disposed on the inner wall of the control frame corresponding to the position of the lithium battery body, the replacement device comprising an adjustment frame and an ejection assembly, the lower surface of the adjustment frame being fixedly connected to the surface of the label shell, a mounting frame being slidably inserted into the inner wall of the adjustment frame, side grooves being provided on both sides of the mounting frame, the two side grooves being interconnected, the inner wall of the side grooves being inserted into the surface of the lithium battery body, circuit boards being electrically connected to both sides of the inner wall of the side grooves, the circuit boards being electrically connected to the lithium battery body, and a plurality of top plates being fixedly connected to the upper surface of the mounting frame corresponding to the position of the lithium battery body, the top plates having a "V" shaped cross section, the top plates being elastic aluminum plates, and the lower surface of the top plates abutting against the surface of the lithium battery body.

[0007] The aforementioned components achieve the following effects: By incorporating a replacement device, when the lithium battery body needs to be replaced, the operator can pull the mounting frame out of the adjustment frame. At this point, the old lithium battery body can be directly removed from the side groove of the mounting frame and replaced with a new one. The top plate, made of a V-shaped elastic aluminum plate, applies downward pressure to the lithium battery body using its elastic deformation, ensuring that the lithium battery body is firmly abutted against the circuit board in the side groove, guaranteeing the stability and reliability of the electrical connection. Simultaneously, its V-shaped structure provides multi-point fixation of the battery, enhancing the battery's stability within the mounting frame. This achieves modular battery installation and convenient replacement, improving maintenance efficiency.

[0008] Preferably, limiting plates are fixedly connected to both sides of the bottom end of the inner wall of the side groove. The cross-section of the limiting plate is arc-shaped, and the surface of the limiting plate abuts against the surface of the lithium battery body.

[0009] The effect achieved by the above components is as follows: by setting the limiting plate, its arc-shaped surface can better fit with the cylindrical lithium battery body surface, providing auxiliary support and limiting the lithium battery body from both sides, preventing the battery from lateral shaking or displacement in the side groove, further improving the stability of battery installation, and ensuring that the electrical connection between the circuit board and the battery will not be interrupted due to vibration or external force.

[0010] Preferably, the ejection assembly includes a slide groove, which is formed on the upper surface of the mounting frame. Sliding brackets are slidably connected to both sides of the inner wall of the slide groove. A top frame is fixedly connected to the bottom of each of the two sliding brackets on one side close to each other. The top frame has a rhomboid cross-section. A connecting plate is fixedly connected to the bottom of the inner wall of the side groove at a position corresponding to the lithium battery body. A sliding rod is slidably passed through the surface of the connecting plate. An adjusting block is fixedly connected to the end of the sliding rod near the top frame. The adjusting block has a pointed conical cross-section, and the side wall surface of the adjusting block abuts against the side wall of the top frame.

[0011] The effect achieved by the above components is as follows: By setting up the ejection assembly, when it is necessary to remove the lithium battery body from the side slot, the operator can slide the sliding frame in the slot. The sliding frame drives the diamond-shaped top frame to move. The side wall of the top frame squeezes the conical adjustment block. Due to the inclined surface of the adjustment block, the horizontal movement of the top frame is converted into the lateral ejection movement of the adjustment block and the slide rod, thereby moving the lithium battery body from the side slot to one side, so that it is no longer in contact with the circuit board, making it easier for the operator to pick up. This solves the problem that the battery is difficult to remove due to tight installation and improves the convenience of replacement operation.

[0012] Preferably, a guide groove is provided on the inner wall surface of the mounting frame at a position corresponding to the top frame, and the inner wall of the guide groove is slidably connected to the bottom surface of the top frame.

[0013] The effect achieved by the above components is as follows: by setting the guide groove, the movement of the top frame can be guided and limited, ensuring that the top frame maintains a stable posture and path during the sliding process, avoiding deflection or jamming, thereby ensuring that the top frame can accurately and smoothly act on the adjusting block, and improving the reliability and stability of the ejection component.

[0014] Preferably, the surface of the adjustment frame is provided with a protective mechanism, which includes two rotating shafts located on opposite sides of one end of the adjustment frame. The arc surfaces of the rotating shafts are rotatably connected to the side walls of the adjustment frame. The ends of the two rotating shafts that are close to each other are fixedly connected to the same flap plate. The cross-sectional dimensions of the flap plate are adapted to the cross-sectional dimensions of the adjustment frame. Connecting grooves are provided on both sides of the adjustment frame. A push plate is slidably connected to the inner wall of the connecting groove. A positioning rod is fixedly connected to one side of the push plate. A positioning frame is slidably connected to the arc surface of the positioning rod. A locking post is fixedly connected to the end of the positioning frame away from the push plate. Two locking slots are provided on both sides of the flap plate. The locking post engages with the inner wall of one of the locking slots on the same side. An adjustment groove is provided on the surface of the adjustment frame corresponding to the locking post. The cross-section of the adjustment groove is vertical. The inner wall of the adjustment groove is slidably connected to the arc surface of the locking post. A spring is fitted on the arc surface of the positioning rod. The two ends of the spring are fixedly connected to one end of the positioning rod and one end of the positioning frame, respectively.

[0015] The aforementioned components achieve the following effects: By incorporating a protective mechanism, the flap can cover the opening of the adjustment frame, providing dust and impact protection for the internal mounting frame and battery components. Through the cooperation of the push plate, positioning rod, positioning frame, spring, and locking pin, the flap can be positioned at different opening angles. For example, when replacing the battery, opening the flap to its maximum angle causes the locking pin to engage with the corresponding slot under spring pressure, securing the flap and preventing it from automatically falling back, thus facilitating operation. The adjustment slot provides a movement path for the locking pin, allowing it to move up and down with the rotation of the flap. The entire structure is simple and reliable, achieving multi-angle hovering functionality for the flap and improving ease of use.

[0016] Preferably, a second coil spring is fitted onto the arc surface of the rotating shaft, and the two ends of the second coil spring are fixedly connected to the inner wall surfaces of the rotating shaft and the adjusting frame, respectively.

[0017] The aforementioned components achieve the following effect: by incorporating a second coil spring, an automatic closing driving force is provided for the rotation of the flap. When the flap is released from its lock, such as by moving the latch to disengage it from the slot, the torque of the second coil spring drives the shaft to rotate, thereby causing the flap to close automatically. This simplifies the operation of closing the flap and ensures that the flap remains closed when not manually opened, enhancing the protective effect.

[0018] Preferably, magnetic sheets are fixedly connected to both ends of the inner wall of the connecting groove, the push plate is a stainless steel plate, and one side surface of the push plate is attracted to the surface of the magnetic sheet.

[0019] The aforementioned components achieve the following effect: by incorporating a magnetic plate that cooperates with a stainless steel push plate, the push plate can be magnetically attracted and fixed to the end of the connecting slot after the operator slides it. This prevents the push plate from sliding due to vibration or spring force when the locking pin is engaged in the slot or in other positions, ensuring the stability of the locked state and providing the operator with a clear tactile feedback of the locking mechanism.

[0020] Preferably, an anti-detachment mechanism is provided on one inner wall of the adjustment frame. The anti-detachment mechanism includes an auxiliary groove, which is formed on the side wall surface of the adjustment frame. A limiting post is fixedly connected to one side surface of the mounting frame. The arc surface of the limiting post is slidably connected to the inner wall of the auxiliary groove. A fixing rod is fixedly connected to the side wall surface of the mounting frame. A stop block is movably connected to the arc surface of the fixing rod. A first coil spring is sleeved on the arc surface of the fixing rod. The two ends of the first coil spring are fixedly connected to the upper end of the stop block and one end of the fixing rod, respectively.

[0021] The aforementioned components achieve the following effects: By incorporating an anti-detachment mechanism, when the mounting frame is inserted into the adjusting frame, the limiting post slides within the auxiliary groove, providing guidance and limitation for the removal of the mounting frame. Simultaneously, under the action of the first coil spring, the stop block naturally droops down, blocking behind the limiting post, thereby preventing the limiting post from sliding out along the auxiliary groove without human intervention. This prevents the mounting frame from accidentally detaching from the adjusting frame, increasing the structural reliability and safety of the equipment.

[0022] Preferably, the cross-section of the stop block is barbed, the stop block is a hard alloy block, and the inner wall of the bottom end of the stop block is engaged with the arc surface of the limiting post.

[0023] The aforementioned components achieve the following effect: by setting the stop block in a barb shape, it can hook or lock the limiting post more tightly and reliably, further enhancing the anti-detachment effect. The stop block is made of hard alloy material, ensuring sufficient strength and wear resistance, allowing it to withstand repeated locking and unlocking operations without easily deforming or being damaged, thus extending the service life of the anti-detachment mechanism.

[0024] Preferably, an adjusting plate is fixedly connected to the lower surface of one side of the flip plate, and an auxiliary plate is fixedly connected to the upper side of the stop block, with the surface of the auxiliary plate rotatably connected to the bottom end of the adjusting plate.

[0025] The aforementioned components achieve the following effect: by setting an adjusting plate and an auxiliary plate, the opening and closing action of the flap is linked to the unlocking action of the anti-detachment mechanism. When the flap is opened, it drives the adjusting plate upward, which in turn pushes the stop block upward via the auxiliary plate. This causes the stop block to overcome the elastic force of the first coil spring and rotate upward, thereby releasing the obstruction of the limiting post. This means that the locking of the mounting frame can only be automatically released at the same time as the flap is opened. The operation is smooth and seamless, achieving the effect of "unlocking upon opening the cover," which not only facilitates the removal operation but also prevents accidental loosening of the mounting frame.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting up a replacement device, when the lithium battery body needs to be replaced, the operator can pull the mounting frame out of the adjustment frame. At this time, the old lithium battery body can be directly taken out from the side groove of the mounting frame and replaced with a new one. The top plate made of V-shaped elastic aluminum plate can apply a downward pressure to the lithium battery body through its elastic deformation, ensuring that the lithium battery body can be firmly abutted against the circuit board in the side groove, ensuring the stability and reliability of the electrical connection. At the same time, its V-shaped structure uses multi-point fixation of the battery to enhance the stability of the battery in the mounting frame. The arc-shaped limiting plate at the bottom of the inner wall of the side groove can provide auxiliary support and limit the cylindrical lithium battery body from both sides, preventing the battery from lateral shaking or displacement, further improving the stability of the battery installation. By setting up an ejection assembly, when the lithium battery body needs to be removed from the side slot, the operator moves the sliding frame to move the diamond-shaped top frame. The side wall of the top frame presses against the conical adjusting block, and the horizontal movement is converted into the horizontal ejection movement of the adjusting block and the slide rod by using the inclined plane. The entire replacement device realizes modular installation and convenient replacement of the battery, which not only ensures the stability of the battery installation and the reliability of the electrical connection, but also solves the disassembly problem through the ingenious ejection structure, which significantly improves maintenance efficiency.

[0027] 2. In this invention, by setting an anti-detachment mechanism, when the mounting frame is inserted into the adjusting frame, the limiting post slides in the auxiliary groove, providing guidance and limitation for the removal of the mounting frame. Simultaneously, under the action of the first coil spring, the stop block naturally droops down, blocking behind the limiting post, thus preventing the limiting post from sliding out along the auxiliary groove without human intervention. This prevents the mounting frame from accidentally falling out of the adjusting frame, increasing the structural reliability and safety of the equipment. Setting the stop block in a hook shape allows for a tighter and more reliable hooking or locking of the limiting post, further enhancing the anti-detachment effect, while the hard alloy material ensures sufficient strength and wear resistance. By setting an adjusting plate and an auxiliary plate, the opening and closing action of the flip plate is linked to the unlocking action of the anti-detachment mechanism. When the flip plate is opened, it drives the adjusting plate upward, which in turn pushes the stop block upward through the auxiliary plate, causing the stop block to overcome the elastic force of the first coil spring and rotate upward, releasing its obstruction of the limiting post. This interconnected design achieves the effect of "unlocking upon opening the cover". The installation frame is automatically unlocked only when the flip panel is opened. The operation is smooth and seamless, which not only facilitates the removal operation but also prevents the installation frame from becoming loose due to accidental operation.

[0028] 3. In this invention, by setting a protective mechanism, the flap can cover the opening of the adjustment frame, providing dust and impact protection for the internal mounting frame and battery components. Through the cooperation of the push plate, positioning rod, positioning frame, spring, and locking pin, the flap can be positioned at different opening angles. When the battery needs to be replaced, the flap is opened to its maximum angle, and the locking pin, under the action of the spring, engages in the corresponding slot, fixing the flap and preventing it from automatically falling back, thus facilitating operation. The adjustment slot provides a movement path for the locking pin, allowing it to move up and down with the rotation of the flap, achieving a multi-angle hovering function. By setting a second coil spring, an automatic closing driving force can be provided for the rotation of the flap. When the flap is unlocked (e.g., by moving the locking pin out of the slot), the torque of the second coil spring drives the rotating shaft to rotate, thereby automatically closing the flap, simplifying the operation steps for closing the flap and ensuring that the flap remains closed when not manually opened. By incorporating a magnetic plate that works in conjunction with a stainless steel push plate, the push plate can be magnetically secured to the end of the connecting slot after the operator slides it. This prevents the push plate from sliding due to vibration or spring force when the locking pin is engaged, ensuring the stability of the locked position and providing the operator with a clear tactile feedback of the locking mechanism. The entire protective mechanism integrates protection, multi-angle positioning, automatic closing, and tactile feedback, significantly improving ease of use and user experience.

[0033] like Figure 1-8 As shown, the present invention provides a price tag housing with replaceable batteries, including a label housing 1, a frame 2 fixedly connected to the bottom of the label housing 1, a price display screen 3 provided on the surface of the label housing 1, a control frame 4 provided on the side of the label housing 1 away from the price display screen 3, a lithium battery body 5 installed inside the control frame 4, a replacement device 6 provided on the inner wall of the control frame 4 corresponding to the position of the lithium battery body 5, a protective mechanism 8 provided on the surface of the adjustment frame 61, and an anti-detachment mechanism 7 provided on one inner wall of the adjustment frame 61.

[0034] The following section will explain the specific settings and functions of its replacement device 6, protection mechanism 8, and anti-detachment mechanism 7.

[0035] like Figure 3 , Figure 4 and Figure 5As shown, the replacement device 6 includes an adjusting frame 61 and an ejection assembly 67. The lower surface of the adjusting frame 61 is fixedly connected to the surface of the label housing 1. An installation frame 62 is slidably inserted into the inner wall of the adjusting frame 61. Side grooves 63 are provided on both sides of the installation frame 62, and the two side grooves 63 are interconnected. The inner wall of the side groove 63 is inserted into the surface of the lithium battery body 5.

[0036] like Figure 7 and Figure 8As shown, the protection mechanism 8 includes two rotating shafts 811, which are located on opposite sides of one end of the adjusting frame 61. The arc surfaces of the rotating shafts 811 are rotatably connected to the side walls of the adjusting frame 61. The ends of the two rotating shafts 811 that are close to each other are fixedly connected to the same flap 801. The cross-sectional dimensions of the flap 801 are adapted to the cross-sectional dimensions of the adjusting frame 61. Connecting grooves 803 are provided on both sides of the adjusting frame 61. Push plates 804 are slidably connected to the inner walls of the connecting grooves 803. A positioning rod 808 is fixedly connected to one side of the push plate 804. A positioning frame 809 is slidably connected to the arc surface of the positioning rod 808. A locking post 806 is fixedly connected to the end of the positioning frame 809 away from the push plate 804. Two locking slots 802 are provided on both sides of the flap 801. 806 engages with the inner wall of one of the slots 802 on the same side. An adjustment groove 807 is provided on the surface of the adjustment frame 61 corresponding to the position of the locking post 806. The cross-section of the adjustment groove 807 is vertical. The inner wall of the adjustment groove 807 is slidably connected to the arc surface of the locking post 806. A spring 810 is sleeved on the arc surface of the positioning rod 808.

The two ends of the second coil spring 812 are fixedly connected to the inner wall surface of the rotating shaft 811 and the adjustment frame 61, respectively. Magnetic sheets 805 are fixedly connected to both ends of the inner wall of the connecting groove 803. The push plate 804 is a stainless steel plate. One side surface of the push plate 804 is attracted to the surface of the magnetic sheet 805.

[0037] like Figure 6 As shown, the anti-detachment mechanism 7 includes an auxiliary groove 72, which is formed on the side wall surface of the adjustment frame 61. A limit post 71 is fixedly connected to one side surface of the mounting frame 62. The arc surface of the limit post 71 is slidably connected to the inner wall of the auxiliary groove 72. A fixing rod 73 is fixedly connected to the side wall surface of the mounting frame 62. A stop block 74 is movably connected to the arc surface of the fixing rod 73. A first coil spring 75 is sleeved on the arc surface of the fixing rod 73. The two ends of the first coil spring 75 are fixedly connected to the upper end of the stop block 74 and one end of the fixing rod 73, respectively. The cross section of the stop block 74 is hook-shaped. The stop block 74 is a hard alloy block. The inner wall of the bottom end of the stop block 74 is engaged with the arc surface of the limit post 71. An adjustment plate 77 is fixedly connected to one lower side surface of the flip plate 801. An auxiliary plate 76 is fixedly connected to one side of the upper end of the stop block 74. The surface of the auxiliary plate 76 is rotatably connected to the bottom end of the adjustment plate 77.

[0038] Its overall working principle is as follows: The price tag housing mainly consists of a label shell 1, a stand 2, a price display screen 3, a control frame 4, and a replacement device 6, a protection mechanism 8, and an anti-detachment mechanism 7 installed within the control frame 4. The lithium battery body 5 serves as the power supply unit, and modular installation is achieved through the replacement device 6.

[0039] In the non-replacement state, the flap 801 of the protection mechanism 8 remains closed under the torque of the second coil spring 812, covering the opening of the adjustment frame 61 and physically isolating the internal mounting frame 62 and lithium battery body 5, providing dust and impact protection. Simultaneously, the first coil spring 75 of the anti-detachment mechanism 7 causes the stop block 74 to hang naturally, its hook-shaped end abutting against the limiting post 71 on the mounting frame 62, preventing the mounting frame 62 from sliding outward along the auxiliary groove 72. This double safety mechanism ensures that the mounting frame 62 will not accidentally loosen due to vibration or external force, guaranteeing the continuous stability of the electrical connection. When the lithium battery needs to be replaced, the operator flips open the flap 801. During the rotation of the flap 801, the adjustment plate 77 on its lower surface lifts upward, and through the auxiliary plate 76 rotatably connected to the adjustment plate 77, the stop block 74 is pushed upward, causing the stop block 74 to overcome the elasticity of the first coil spring 75 and rotate upward, thereby releasing the obstruction of the limiting post 71. This design achieves a "open the cover and unlock" linkage effect, ensuring smooth and continuous operation. After unlocking, the operator can pull the mounting frame 62 out of the adjusting frame 61. If the battery is difficult to remove due to tight contact, the ejection component 67 in the replacement device 6 can be activated: the sliding frame 672 moves along the slide groove 671, causing the diamond-shaped top frame 673 to move. The side wall of the top frame 673 presses against the inclined surface of the conical adjusting block 676, converting the horizontal movement into the horizontal pressing motion of the slide rod 677, thereby ejecting the lithium battery body 5 horizontally, detaching it from contact with the circuit board 66, and making it easy to remove. When installing a new battery, the lithium battery body 5 is placed in the side groove 63. The V-shaped elastic top plate 64 uses its elasticity to apply downward pressure to the battery, ensuring that the battery is firmly against the circuit board 66. At the same time, the arc-shaped limiting plate 65 at the bottom of the side groove 63 provides auxiliary support from both sides to prevent shaking, pushing the mounting frame 62 back into the adjusting frame 61, and the limiting post 71 slides inward along the auxiliary groove 72. Once the mounting frame 62 is fully in place, the stop block 74 automatically resets and droops under the action of the first coil spring 75, blocking the limit post 71 again to achieve automatic locking. Finally, the flap 801 is closed. The operator can push the flap 801 to the closed position, where the locking post 806 engages with the corresponding slot 802 under the action of the spring 810 for positioning, or it can be automatically closed by the second coil spring 812, and the push plate 804 is attracted by the magnetic sheet 805 to provide a clear tactile feel for the position, thus completing the entire replacement process.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
