A battery charging device

Abstract

This utility model relates to a battery charging device, the structure of which includes an outer shell and an internal support plate, the support plate being used to support and fix the battery. The innovation of this device lies in the multiple clamping plates provided on the support plate, with the clamping plate on the rear side of the support plate serving as a drive plate, and the clamping plates on the left and right sides serving as positioning plates. Furthermore, each clamping plate has a linkage telescopic mechanism at its end furthest from the support plate. The linkage telescopic mechanisms of the drive plate and the positioning plates are connected by a rope transmission system. When the operator inserts the battery into the outer shell, the rear end of the battery first contacts the drive plate and pushes it backward, causing the length of the linkage telescopic mechanism of the drive plate to shorten, while the length of the linkage telescopic mechanism of the positioning plate increases. This results in relative movement of the positioning plates, reducing the gap between them and the battery, thereby achieving stable battery clamping. This design ensures the stability and safety of the charging process.

Description

Technical Field

[0001] This utility model relates to the field of battery charging device technology, and in particular to a battery charging device. Background Technology

[0002] A battery charging device, as a device to replenish electrical energy to a battery, transmits electrical energy to the battery through a power source, causing a chemical reaction to reverse, thereby achieving energy storage.

[0003] In existing technologies, the structural characteristics of batteries make them susceptible to external impacts, which can lead to hazards, especially during charging when heat accumulation significantly increases the risk. Therefore, battery charging devices often incorporate limiting mechanisms to prevent the battery from colliding with the inner walls (such as the outer casing).

[0004] However, existing limiting mechanisms typically consist of a screw and a clamping plate. The position of the clamping plate is adjusted by rotating the screw, and the relative movement between the battery and the battery charging device is limited by the interference fit between the clamping plate and the battery. In existing devices, the screw rotation is often driven manually or electrically.

[0005] Therefore, in practical applications, both electric and manual screw rotation methods for securing the battery require a significant amount of time. Based on this, this study argues for the need to develop a novel battery charging device that eliminates the need for a screw and automatically secures the battery during insertion and removal. Utility Model Content

[0006] To address the limitations of existing technologies, this utility model proposes a battery charging device that offers advantages such as convenient operation and short operation time, thus solving the problem of extended operation time caused by waiting for the limit mechanism to activate in existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A battery charging device includes a housing with a support plate inside. Multiple clamping plates are arranged equidistantly around the vertical center line of the support plate on its upper side. The clamping plate located at the rear of the support plate is a drive plate, and the clamping plates located on the left and right sides of the support plate are positioning plates. A linkage telescopic mechanism is provided at the rear of each clamping plate. The linkage telescopic mechanism at the rear of the drive plate and the linkage telescopic mechanism at the rear of the positioning plates are connected by a pull rope. When the drive plate moves backward, the two positioning plates move towards each other.

[0009] Preferably, the linkage telescopic mechanism includes two symmetrically arranged driven rods, and the near ends of the two driven rods in each linkage telescopic mechanism are rotatably connected by a pin, and the far ends of the two driven rods in each linkage telescopic mechanism are fixedly connected to the outer shell and the clamping plate, respectively.

[0010] Preferably, each of the pins is fitted with a follower, the follower having a through hole, and both ends of each pull rope are movably connected to the corresponding through hole.

[0011] Preferably, each clamping plate is fixedly connected to a telescopic rod on the side away from the support plate. One end of the telescopic rod is fixedly connected to the corresponding clamping plate, and the other end of the telescopic rod is fixedly connected to the outer shell. Furthermore, a compression spring is sleeved on the outside of the telescopic rod, and the two axial ends of the compression spring abut against the inner wall of the corresponding clamping plate and the outer shell, respectively.

[0012] Preferably, a plurality of rollers are fixedly connected to the inner wall of the outer shell, and the plurality of rollers correspond one-to-one with a plurality of pull ropes, and the middle section of each pull rope is sleeved on the outside of the corresponding roller.

[0013] Preferably, the projection of the support plate on the vertical plane is an L-shaped structure, and the vertical section of the support plate is located on the side away from the clamping plate.

[0014] Preferably, each clamp plate has multiple rubber contact pads fixedly connected to the side near the support plate, and the multiple contact pads are arranged in a rectangular array on the corresponding clamp plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention designs a battery clamping device that utilizes a linkage telescopic mechanism in conjunction with a pull rope. When the operator inserts the battery, the rear end of the battery pushes the drive plate backward, causing the drive plate linkage telescopic mechanism to shorten. Simultaneously, the positioning plate linkage telescopic mechanism extends, driving the positioning plate to move relative to the battery, reducing the gap between the positioning plate and the battery, and ensuring stable clamping. Compared with existing technologies, this device requires no additional setup by the operator in practical applications, nor does it require electronic control components to assist in clamping the battery, effectively achieving battery clamping and fixation at low cost. Furthermore, the drive plate and the linkage telescopic mechanism on the rear side of the positioning rod are connected by a transmission, utilizing the mutual restraint mechanism between them to enhance the impact resistance of the battery inside the casing and effectively suppress the relative displacement of the battery.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please see Figure 1 A battery charging device, with a structure similar to existing technologies, includes a housing 2, inside which a support plate 1 for placing the battery is provided. The device is designed to provide an efficient charging solution, where the housing 2 not only protects the internal components, but the internal support plate 1 also provides a stable placement for the battery.

[0026] It is worth noting that the structure of outer shell 2 may be related to Figure 1 There are differences; the front side can be equipped with multiple placement slots, each with a built-in support plate to support simultaneous charging of multiple batteries.

[0027] The outer casing 2 is a closed structure, and a cabinet door can be installed on the front to protect the battery. This application omits the upper cover and the front cabinet door structure for ease of understanding.

[0028] Please see Figure 2 , Figure 3The difference between this device and existing devices lies in the fact that multiple clamping plates 4 are provided on the upper side of the support plate 1 for fixing the battery. These clamping plates 4 are arranged equidistantly along the vertical center line of the support plate 1. This structural design ensures the battery is firmly fixed in the charging device, thereby guaranteeing the stability and safety of the charging process.

[0029] In particular, the clamping plate 4 on the rear side of the support plate 1 is specially designed as a drive plate 401, while the clamping plates 4 on the left and right sides of the support plate 1 serve as positioning plates 402.

[0030] In addition, each clamping plate 4 is equipped with a linkage telescopic mechanism 3 on its rear side. Specifically, as follows: Figure 4 As shown, each linkage telescopic mechanism 3 includes two symmetrically arranged driven rods 301. The proximal ends of the two driven rods 301 in each linkage telescopic mechanism 3 are rotatably connected by a pin 302, and the distal ends of the two driven rods 301 in each linkage telescopic mechanism 3 are fixedly connected to the outer shell 2 and the clamping plate 4, respectively.

[0031] Meanwhile, this device has a follower 303 on the outer side of each pin 302, and the follower 303 has a through hole 304. Therefore, this device is connected to the linkage telescopic mechanism 3 on the rear side of the drive plate 401 and the linkage telescopic mechanism 3 on the rear side of the positioning plate 402 via a pull rope 6, and both ends of each pull rope 6 are movably connected to the corresponding through hole 304. This allows the device to adjust the orientation of the two linkage telescopic mechanisms 3 at both ends of each pull rope 6, such as... Figure 3 As shown, by constraining the two linkage telescopic mechanisms 3 to face the same direction, the working states of the two linkage telescopic mechanisms 3 corresponding to each linkage 6 can be completely opposite when the pull rope 6 is in action. That is, when the length of one linkage telescopic mechanism 3 decreases, the length of the other linkage telescopic mechanism 3 can increase under the action of the pull rope 6. This ensures that when the drive plate 401 moves backward, the two positioning plates 402 can move towards each other, thereby achieving stable clamping of the battery.

[0032] It should be noted that in actual operation, the operator pushes the battery into the outer casing 2. The rear end of the battery first touches the drive plate 401, and then the battery continues to be pushed in, causing the drive plate 401 to move backward. At this time, the linkage telescopic mechanism 3 connected to the drive plate 401 shortens, and at the same time, the pull rope 6 pulls the linkage telescopic mechanism 3 corresponding to the two clamping plates 4 to extend, causing the two positioning plates 402 to move towards each other and gradually approach the battery, thereby achieving the effect of fixing the battery together through the positioning plates 402 and the drive plate 401.

[0033] Furthermore, to ensure that the battery can be fixed at multiple points and that the battery is stable during insertion into the outer casing 2, and that the battery does not move forward due to the reaction force applied to the battery by the drive plate 401, this device specifies that the projection of the support plate 1 in the vertical direction is an L-shaped structure, and the vertical section of the support plate 1 is located on the side away from the clamping plate 4, so that the support plate 1 can better support the battery.

[0034] Furthermore, such as Figure 2 As shown, each positioning plate 402 is equipped with at least two linkage telescopic mechanisms 3 to avoid unilateral force and ensure linear movement of the positioning plate 402. This design enhances the balance of the positioning plate 402 during movement, thereby improving the overall stability and reliability of the device.

[0035] Furthermore, such as Figure 2 , Figure 3 As shown, to avoid relative sliding between the pull rope 6 and the clamping plate 4, which would increase the wear of the pull rope 6, multiple rollers 5 are fixedly connected to the inner wall of the outer casing 2. Each roller 5 corresponds to one pull rope 6, and the middle section of each pull rope 6 is sleeved on the outside of the corresponding roller 5. This design keeps the pull rope 6 away from the clamping plate 4, effectively preventing friction between the pull rope 6 and the clamping plate 4 during actual use.

[0036] It is worth noting that the roller 5 is located at one end of the linkage telescopic mechanism 3 near the inner wall of the outer casing 2. This arrangement ensures that the pull rope 6 is kept away from the clamping plate 4, thus avoiding friction.

[0037] Furthermore, in order to achieve automatic reset of multiple clamping plates 4, the device is equipped with a compression spring 9 on the side of each clamping plate 4 away from the support plate 1. The two axial ends of the compression spring 9 abut against the corresponding clamping plate 4 and the inner wall of the outer shell 2, respectively. By utilizing the characteristics of the movement direction of the positioning plate 402 and the drive plate 401, the elastic force of the compression spring 9 is balanced with each other, thereby realizing the automatic reset of the clamping plate 4.

[0038] In addition, the device is equipped with a telescopic rod 8 on the side of each clamping plate 4 away from the support plate 1. One end of the telescopic rod 8 is fixedly connected to the corresponding clamping plate 4, and the other end of the telescopic rod 8 is fixedly connected to the outer shell 2. The telescopic rod 8 is used to constrain the movement trajectory of the clamping plate 4 to ensure that the movement trajectory of the clamping plate 4 always meets the expectations.

[0039] Furthermore, the device has a rubber contact pad 7 fixedly connected to each clamping plate 4 on the side near the support plate 1. The presence of the contact pad 7 can avoid direct contact between the clamping plate 4 and the battery, ensuring that the clamping plate 4 and the battery can be interference-fitted so as to fully fix the battery by using clamping force.

[0040] It should be noted that the contact pads 7 are numerous and small in diameter, arranged in a rectangular array on the clamping plate 4. This forms anti-slip grooves to enhance battery fixation and ensures that the battery is in full contact with the air, preventing heat buildup during charging from causing accidents.

[0041] In the practical application of this utility model:

[0042] First, the operator pushes the battery into the casing, and the rear end of the battery gradually approaches the drive board 401.

[0043] Subsequently, the battery pushes the drive plate 401 to move backward, the length of the linkage telescopic mechanism 3 decreases, and the compression spring 9 accumulates potential energy; at the same time, the linkage telescopic mechanism 3 on the side of the positioning plate 402 extends, and its spring releases potential energy.

[0044] Next, the battery is continuously pushed into the housing 2 until it is fully embedded in the L-shaped opening of the support plate 1. At this point, the contact pad 7 and the battery achieve an interference fit.

[0045] Finally, when it is necessary to remove the battery, the operator lifts the battery diagonally upward. During this process, the drive plate 401 moves forward with the battery, the compression spring 9 corresponding to the drive plate 401 releases elastic potential energy, and the compression spring 9 corresponding to the positioning plate 402 gradually accumulates elastic potential energy until the elastic force on the positioning plate 402 and the elastic force on the drive plate 401 are rebalanced. Then the drive plate 401 separates from the battery and remains stationary.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
