Description

Technical Field

[0001] The utility model relates to the technical field of burning firmware, in particular to a storage card protection device used for burning firmware on a charger control board. Background Art

[0002] Firmware is a program written into EPROM (erasable programmable read-only memory) or EEPROM (electrically erasable programmable read-only memory). Of the two media, EPROM is usually soldered on a circuit board. During the firmware burning process, each circuit board must be operated separately, which is cumbersome and difficult to replace after a failure. However, EEPROM can be directly plugged into other circuit boards of the same model after the firmware is burned on one circuit board, which is more convenient and easy to replace. Therefore, for the sake of convenience in production and easy later maintenance, the applicant will burn the firmware of the control board into the memory card in the charger product.

[0003] At present, the burning process mainly uses a control board as a medium. After inserting the memory card into the slot on the control board, the firmware is burned into the memory card using the data interface on the control board. Then the burned memory card is removed and a new memory card is inserted for burning again. During the entire burning process, the operator needs to estimate whether the burning process is completed based on the burning time based on experience. If the operator accidentally pulls out the memory card before the burning is completed, it will cause firmware damage or even physical damage to the memory card. In order to solve this problem, a simple idea is to set an indicator on the control board that can prompt the operator after the burning process is completely completed. However, because the burning process is usually performed only once, setting an additional indicator on the control board will bring unnecessary costs and require adjustment of the circuit design, which is more cumbersome.

[0019] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts not described and disclosed in detail in the following embodiments of the present invention should be understood as the prior art known or should be known to those skilled in the art, such as the structure and model of the charger control board 3, how to burn the memory card 301, the structure and model of the memory card 301, the structure and model of the switch, the wiring of the data interface between the switch and the charger control board 3, etc.

[0020] Example 1

[0021] A memory card protection device for burning firmware on a charger control board, such as Figure 1 As shown, it includes a placement plate 1 and a protection plate 2. The placement plate 1 is provided with a placement slot 101 for placing the control board 3. The size of the placement slot 101 is slightly larger than the size of the control board 3. The protection plate 2 is fixedly connected to the placement plate 1, and the protection plate 2 extends to the top of the placement slot 101. A limiting space is formed between the protection plate 2 and the bottom wall of the placement slot 101. When the control board 3 is placed in the placement slot 101, a part of the memory card 301 on the control board 3 can enter the limiting space, and then the power switch 4 is turned on, and the firmware is burned into the memory card 301 using the data interface on the control board 3. In this process, the operator will not pull out the memory card 301 on the control board 3 before the burning process is completed, which will damage the firmware or even physically damage the memory card 301.

[0022] The above is a basic implementation method of the utility model, which can be further improved, optimized and limited on the basis of the above to obtain the following embodiments:

[0023] Example 2

[0024] This embodiment is an improved solution based on the embodiment 1, and its main structure is the same as that of the embodiment 1, and the improvement is that: the bottom wall of the placement groove 101 is provided with a plurality of pads 103 for supporting the control board 3, so as to avoid the inconvenience of taking the control board 3 due to the placement groove 101 being too deep.

[0025] Example 3

[0026] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is as follows: Figure 2 As shown, a limiting space is formed between the bottom of the placement plate 1 and the bottom wall of the placement slot 101. If the distance between the bottom of the placement plate 1 and the bottom wall of the placement slot 101 is too large, it is easy for the control board 3 to be taken out of the placement slot 101, and the memory card 301 will be damaged when the firmware is being burned. Therefore, a through slot 102 is provided on the placement plate 1, and the protective plate 2 is arranged in the through slot 102. The placement plate 1 and the protective plate 2 are connected by bolts 202. The placement plate 1 is provided with a first connection hole, and the protective plate 2 is provided with a second connection hole. The bolts 202 pass through the first connection hole and the second connection hole in sequence and are screwed with the first connection hole and the second connection hole in sequence.

[0027] A plurality of protrusions 5 are arranged on the side wall of the placement groove 101, and the protrusions 5 can extend into the notches on the side of the control board 3, and there is a gap between the protrusions 5 and the grooves. It is better adapted to the control board 3, and the existence of the gap does not affect the placement of the control board 3 in the placement groove 101. In order to save costs, there is a distance between the lower surface of the protrusion 5 and the bottom wall of the placement groove 101.

[0028] Example 4

[0029] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is as follows: Figure 3 and Figure 4As shown, after the control board 3 is placed in the placement slot 101 for firmware burning, when the control board 3 is taken out, the control board 3 can only be taken out sideways, which is inconvenient to operate. Therefore, a receiving chamber 106 is opened at the bottom of the placement slot 101, and a self-locking switch is arranged in the receiving chamber 106. The self-locking button of the self-locking switch can extend out of the receiving chamber 106. The bearing plate 104 that can support the control board 3 is rotatably arranged in the placement slot 101, and the bottom of the bearing plate 104 can contact the self-locking button. When the operator places the control board 3 in the placement slot 101, the bearing plate 104 will be pressed to rotate downward, so that the self-locking button is squeezed and moved into the receiving chamber 106 and locked, and the firmware can be burned at this time; after the firmware burning is completed, the operator only needs to press the surface of the control board 3, and the bearing plate 104 will be squeezed by the control board 3 and will also rotate downward and squeeze the self-locking button. At this time, the locking state of the self-locking switch is released, and the self-locking button resets and rotates upward against the bearing plate 104, thereby driving the control board 3 to move upward for the operator to take it out.

[0030] Example 5

[0031] This embodiment is an improved solution based on the embodiment 4. Its main structure is the same as that of the embodiment 4. The improvement is as follows: Figure 3 and Figure 4 As shown, the carrier plate 104 is set to be rectangular, and the long side of the carrier plate 104 is parallel to the long side of the placement groove 101. The carrier plate 104 is provided with a first through hole along its length direction, and a rotating shaft 105 is passed through the first through hole. Second through holes for the rotating shaft 105 to pass through are provided on the two side walls of the placement groove 101, and the protruding part is fixedly connected to a limiting block. The existence of the limiting block can limit the rotating shaft 105 while the carrier plate 104 is rotating. In order to avoid the distance between the lower surface of the protective plate 2 and the upper surface of the carrier plate 104 being too small to affect the storage card 301 on the control board 3 from entering the limited space, the height difference between the lower surface of the protective plate 2 and the upper surface of the carrier plate 104 is greater than the height of the control board 3.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
