Description

Technical Field

[0001] The present invention relates to the technical field of battery protection plates, and in particular to a protection plate for a detachable battery. Background Art

[0002] The protection board is a component used to enhance the safety and stability of the battery. This protection board usually integrates some key functions, such as overcharge protection, over-discharge protection and short-circuit protection, to ensure the safety of the battery during use.

[0003] With the popularity of portable electronic devices, removable batteries have been widely used in many fields due to their convenient replacement and maintenance. However, there are some shortcomings in the design of the existing protective plates for removable batteries. Traditional protective plates usually need to rely on tape or other adhesive materials to connect to the battery. This connection method is not only inconvenient to install, but also over time, the battery is frequently disassembled, and the tape may lose its stickiness, causing the connection between the protective plate and the battery to become unstable. In addition, when the removable battery is frequently plugged in or out or impacted by external forces, it is easy to loosen between the battery slot of the device, reducing the reliability of the electrical contact of the battery, which not only affects the normal operation of the device, but may also cause poor contact and even cause safety accidents. Although there are some improvement measures on the market to try to solve these problems, such as enhancing the fixing effect by changing the design of the battery slot, these methods are difficult to meet the requirements of ease of use and reliability at the same time, and for a large number of existing devices, the modification cost is high and the implementation is difficult.

[0004] In order to solve the above problems, we propose a protective plate for a removable battery. The protective plate has a fixed structure and can be directly fixed on an existing removable battery, making installation more convenient. The protective plate can also reinforce the removable battery to maintain good electrical connection and physical stability between the battery and the battery slot. Summary of the invention

DETAILED DESCRIPTION

[0028] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] Embodiment 1: A protective plate for a removable battery, such as Figure 1-Figure 6As shown, it includes a protection plate body 1, a guide frame 2, a mounting clamp 3, a bidirectional screw 4, a first top block 5, a second top block 6, an extrusion assembly and a clamping assembly. The protection plate body 1 is L-shaped, and the connection between the vertical part and the horizontal part of the protection plate body 1 can be deformed and bent. The right part of the protection plate body 1 is fixedly connected to the guide frame 2, and the guide frame 2 is slidably connected to the front and rear symmetrical mounting clamps 3. The middle part of the guide frame 2 is rotatably connected to the bidirectional screw 4, and the middle part of the bidirectional screw 4 is provided with a rotating wheel. The mounting clamp 3 and the bidirectional screw 4 are connected. Through threaded connection, the first top block 5 is slidably connected to the upper inner part of the rear mounting clamp plate 3, and the second top block 6 is slidably connected to the upper inner part of the front mounting clamp plate 3. The second top block 6 is slidably connected to the first top block 5. An extrusion assembly is provided on the first top block 5, the second top block 6 and the mounting clamp plate 3. The extrusion assembly is used to control the first top block 5 and the second top block 6 to be ejected upward and strengthen the connection between the battery and the battery slot. A clamping assembly is provided on the protection plate body 1, and the clamping assembly is used to fix the vertical part of the protection plate body 1 after bending.

[0030] When using the device, the staff drives the two-way screw 4 to rotate through the rotating wheel, and the rotation of the two-way screw 4 drives the installation clamping plate 3 to slide back and open, and then the staff moves the device to the side of the battery where the protective plate needs to be installed, so that the lower side of the protective plate body 1 is butted against and fits with the upper side of the battery. At this time, the front and rear two installation clamping plates 3 are sleeved on the battery, and then the staff controls the rotating wheel to reverse, and the reversal of the rotating wheel drives the two-way screw 4 to reverse, and the reversal of the two-way screw 4 drives the installation clamping plates 3 to slide toward each other, and the installation clamping plates 3 slide toward each other to clamp the battery, and then fix the device on the battery. After the horizontal part of the protective plate body 1 is fixed, the staff controls the vertical part of the protective plate body 1 to bend downward and fit with the horizontal part, and then The bent vertical portion is fixed by the locking assembly. At this time, the protection board body 1 is installed on the upper side of the battery and fits with the battery. When the staff installs the battery into the battery slot of the device, the extrusion assembly will squeeze the first top block 5 and the second top block 6 to slide upward and extend. After the first top block 5 and the second top block 6 extend upward, they are close to the inner wall of the battery slot of the device, thereby filling the gap between the battery and the battery slot, so that the battery is more firmly embedded in the battery slot of the device to prevent the battery from loosening. In this way, the protection board body 1 can be directly fixed on the existing removable battery, which is more convenient to install. At the same time, the removable battery can also be reinforced to maintain a good electrical connection and physical stability between the battery and the battery slot.

[0031] like Figure 1 , Figure 3 and Figure 4As shown, the extrusion assembly includes a sliding plate 7, an extrusion block 8, a limiting frame 9, a contact plate 10 and an extrusion rod 11. The first top block 5 is slidably connected to the sliding plate 7 which is symmetrical on the left and right. The rear mounting clamp 3 is slidably connected to the extrusion block 8. The extrusion block 8 is wedge-shaped. The extrusion block 8 slides forward to extrude the sliding plate 7 to move upward. The first top block 5 is slidably connected to the limiting frame 9. The lower side of the limiting frame 9 contacts the upper side of the sliding plate 7. The right part of the limiting frame 9 is fixedly connected to the contact plate 10. The second top block 6 is slidably connected to the extrusion rod 11 on the upper right side. The side of the contact plate 10 close to the extrusion rod 11 is inclined. The rear part of the extrusion rod 11 passes through the upper right part of the first top block 5 and is extruded and matched with the contact plate 10.

[0032] When the staff loads the battery into the battery slot of the device, the squeezing block 8 enters the battery slot and is squeezed to slide forward. The squeezing block 8 slides forward and squeezes the sliding plate 7 to move upward. The sliding plate 7 moves upward and pushes the first top block 5 to slide upward through the limiting frame 9. The first top block 5 slides upward and drives the second top block 6 to slide upward. The first top block 5 and the second top block 6 extend upward and then stick to the inner wall of the battery slot of the device, thereby filling the gap between the battery and the battery slot, so that the battery is more firmly embedded in the battery of the device to prevent the battery from loosening. When the battery needs to be removed, the staff pushes the squeezing rod 11 to slide backward, and the squeezing rod 11 slides backward to squeeze the contact plate 10 to slide left. The contact plate 10 slides left and drives the limiting frame 9 to slide left. After the limiting frame 9 slides left, it disengages from the sliding plate 7. At this time, the first top block 5 can slide downward on the sliding plate 7, thereby loosening the connection between the battery and the battery slot so that the battery can be removed from the battery slot.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the locking assembly includes a mounting rod 12, a locking plate 13 and a torsion spring 14. The right part of the protection plate body 1 is fixedly connected to a front-to-back symmetrical mounting rod 12, and a locking plate 13 is rotatably connected to the mounting rod 12. The upper end of the locking plate 13 is a hook-shaped structure, and a left-right symmetrical torsion spring 14 is connected between the locking plate 13 and the adjacent mounting rod 12.

[0034] When using the device, after the horizontal part of the protection plate body 1 is fitted and docked with the battery, the staff controls the vertical part of the protection plate body 1 to bend downward and fit with the horizontal part. After the vertical part of the protection plate body 1 is bent downward, it contacts the locking plate 13, and then squeezes and rotates outward, and the torsion spring 14 is deformed. When the vertical part of the protection plate body 1 rotates downward and separates from the hook-shaped structure at the upper end of the locking plate 13, under the action of the torsion spring 14 resetting, the locking plate 13 rotates inward and resets, and then the vertical part of the protection plate body 1 is clamped by the hook-shaped structure at the upper end to prevent the protection plate body 1 from loosening.

[0035] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 7 As shown, it also includes a reinforcement component for reinforcing the protection plate body 1, the reinforcement component includes a first reinforcement plate 15, a sliding block 16, a second reinforcement plate 17 and an adjusting rod 18, the first reinforcement plate 15 is slidably connected to the left rear side of the protection plate body 1, the sliding block 16 is slidably connected to the left front side of the protection plate body 1, the second reinforcement plate 17 is slidably connected to the lower part of the sliding block 16, the adjusting rod 18 is rotatably connected to the lower part of the sliding block 16, and the adjusting rod 18 is threadedly connected to the second reinforcement plate 17.

[0036] When using the device, the staff turns the adjusting rod 18, and the rotation of the adjusting rod 18 drives the second reinforcement plate 17 to slide forward on the sliding block 16. When the protection plate body 1 is attached to the upper side of the battery, the first reinforcement plate 15 and the second reinforcement plate 17 are respectively located on the front and rear sides of the battery. Then the staff controls the adjustment rod 18 to reverse, and the reversal of the adjustment rod 18 drives the second reinforcement plate 17 to slide backward. The second reinforcement plate 17 slides backward and cooperates with the first reinforcement plate 15 to clamp the battery again, thereby reinforcing the left part of the protection plate body 1, so that the protection plate body 1 is installed more firmly, and the sliding block 16 and the first reinforcement plate 15 can slide on the protection plate body 1, and then adjust the position of the reinforcement clamping according to the actual situation of the battery.

[0037] like Figure 1 and Figure 8 As shown, it also includes a fixing component for fixing the position of the first reinforcement plate 15 and the sliding block 16, the fixing component includes a guide rod 181, a positioning card plate 19, a lower pressure block 20 and a limiting inclined block 21, the front and rear sides of the left and right parts of the protection plate body 1 are fixedly connected with the guide rod 181, and the positioning card plate 19 is slidably connected between the two corresponding guide rods 181 on the left and right. The positioning card plate 19 is provided with equidistantly distributed convex teeth on the side close to the protection plate body 1, and the first reinforcement plate 15 and the sliding block 16 are provided with a card groove adapted to the convex teeth of the positioning card plate 19. The upper parts of the first reinforcement plate 15 and the sliding block 16 are slidably connected with the lower pressure block 20, the vertical part of the protection plate body 1 is bent downward to be extruded and matched with the lower pressure block 20, and the lower part of the lower pressure block 20 is fixedly connected with the limiting inclined block 21, and the limiting inclined block 21 moves downward to squeeze the positioning card plate 19 to slide inward.

[0038] When using the device, when the vertical part of the protection plate body 1 is bent downward, the pressing block 20 will be squeezed to slide downward, and the downward sliding of the pressing block 20 will drive the limiting bevel block 21 to move downward. After the limiting bevel block 21 moves downward, it squeezes the positioning card plate 19 to slide inward. After the positioning card plate 19 slides inward, it is stuck in the sliding block 16 and the first reinforcement plate 15, thereby fixing the position of the sliding block 16 and the first reinforcement plate 15, to avoid abnormal sliding of the sliding block 16 and the first reinforcement plate 15 affecting the reinforcement effect after the device is installed.

[0039] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
