Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

A universal reset recognizer 100 according to embodiments of the present invention is described below with reference to fig. 1-5. The universal reset identifier 100 may be applied to a chip, such as a chip of a printer (not shown). In the following description of the present application, the universal reset identifier 100 is illustrated as applied to a chip.

As shown in fig. 1 to 4, the universal reset recognizer 100 according to the embodiment of the present invention includes a housing 1, a main board 2, a recognition pin 21, and a selection device.

Specifically, the main board 2 is disposed in the housing 1, the number of the identification pins 21 includes one or more, each identification pin 21 is disposed on the main board 2, each identification pin 21 includes a sleep state and an operating state, the sleep state and the operating state of the identification pin 21 include a plurality of different combination modes, each combination mode at least includes that part or all of the identification pins 2 are in the operating state, the selection device is mounted on the housing 1, and the combination modes of the sleep state and the operating state of the identification pins 21 can be switched through the selection device.

For example, in the examples of fig. 1 to 4, the main board 2 is provided with a plurality of identification pins 21, the identification pins 21 may be in a sleep state or an operating state, when the identification pins 21 are in the operating state, the identification pins 21 are in contact with the chip, so that the identification pins 21 are electrically connected with the chip, when the identification pins 21 are in the sleep state, the identification pins 21 are not in contact with the chip, and the identification pins 21 are disconnected from the chip. Therefore, through the arrangement, different types of chips can be programmed by switching the combination mode of the dormant state and the working state of the identification needle 21 through the selection device, and the whole universal reset identifier 100 is simple in structure, small in size and convenient to carry.

According to the universal reset identifier 100 of the embodiment of the invention, the identifier 21 and the selection device are arranged in the dormant state and the working state, the dormant state and the working state of the identifier 21 comprise various different combination modes, and the combination mode of the identifier 21 can be switched through the selection device, so that the switching of different chip identification resets can be realized, and compared with the traditional reset identification device provided with a plurality of identification heads, the whole universal reset identifier 100 is simple in structure, small in size and convenient to carry.

In some embodiments of the invention, referring to fig. 1-4, the selection means comprises a slide 3 and a flap 31. Specifically, the slide cover 3 is switched between the extended position and the retracted position with respect to the housing 1, the shutter 31 is detachably mounted to the slide cover 3, the shutter 31 has a pin hole 32, the plurality of identification pins 21 are housed therein when the slide cover 3 is in the extended position and the shutter 31 is provided on the slide cover 3, and the sleep state and the operating state of the identification pins 21 are combined in a predetermined combination when the slide cover 3 is in the retracted position.

For example, in the example of fig. 2 to 5, the main board 2 is provided in the housing 1, the plurality of identification pins 21 are provided at one end (e.g., the right end in fig. 4) of the main board 2, and the plurality of identification pins 21 may be combined in various ways. The baffle 31 is arranged on the sliding cover 3 and can be replaced, and the pinholes 32 on different baffles 31 can have various different arrangement modes corresponding to different chips. For example, referring to fig. 5, the number of the needle holes 32 of the baffle 31 may be two, three, four, or four or more; some of the baffles 31 have the same number of needle holes 32 as some of the other baffles 31, but the arrangement of the needle holes 32 is different or the spacing between the needle holes is different.

When different chips are to be programmed, the corresponding shutter 31 may be mounted on the slide cover 3 such that the identification pin 21 aligned with the pin hole 32 protrudes from the corresponding pin hole 32 of the shutter 31, and the protruding identification pin 21 may be in an operating state so as to contact the contact point on the chip. The identification pin 21 not protruding from the pin hole 32 may be in a dormant state. The protruding identification pin 21 may be in a sleep state unless it is in contact with a terminal on the chip. A combination of the sleep state and the operation state of each identification pin 21 will be described by taking three needle holes 32 in the shutter 31 as an example: when the sliding cover 3 is located at the extended position, the plurality of identification needles 21 are covered in the sliding cover 3, and the sliding cover 3 is provided with the baffle 31 with three needle holes 32, when the sliding cover 3 is located at the retracted position, the three needle holes 32 can respectively have the identification needles 21 extended, the identification needles 21 extended from the needle holes 32 can be in a working state, and the identification needles 21 not extended from the needle holes 32 can be in a dormant state.

The barrier 31 has a needle hole 32, and the needle hole 32 of the barrier 31 corresponds to a part of the plurality of identification pins 21. Here, the following two cases are included: firstly, the pinholes 32 on the baffle 31 can have only one arrangement mode to correspond to contacts on a chip, and at this time, the chip can be only burned; secondly, the pin holes 32 on the baffle 31 can also correspond to contacts on various chips, and the corresponding various chips can be burnt.

The slide cover 3 can be moved relative to the housing 1 in order to exchange different flaps 31. When the sliding cover 3 is located at the retraction position, the identification needle 21 corresponding to the chip extends out of the needle hole 32, so that the identification and the reset of the chip are realized; after the chip programming is completed, the sliding cover 3 can be moved from the retracted position to the extended position, at this time, the identification pins 21 are extended from the pin holes 32, and all the identification pins 21 are covered in the sliding cover 3. When the sliding cover 3 is located at the extending position, the baffle 31 can be replaced according to different types of chips, so that the switching of identification and resetting among different chips is realized.

In some embodiments of the present invention, referring to fig. 2-4, at least one latch hook structure 4 is provided between the housing 1 and the sliding cover 3, the latch hook structure 4 comprising a first latch hook assembly 41 and a second latch hook member 42. The first latch element 41 is disposed on the housing 1, the second latch hook element 42 is disposed on the sliding cover 3, when the sliding cover 3 is located at the retracted position, the first latch element 41 locks the second latch hook element 42 to keep the sliding cover 3 at the retracted position, and an external force is applied to the first latch element 41 to disengage the first latch element 41 from the second latch hook element 42 to make the sliding cover 3 movable from the retracted position to the extended position.

For example, in the example of fig. 2-4, when the slide cover 3 is in the retracted position, the first latch hook member 41 and the second latch hook member 42 remain hooked to limit the movement of the slide cover 3 relative to the housing 1, at which time the burning of the corresponding chip can be completed. When an external force is applied to the first latch member 41, the first latch member 41 and the second latch member 42 are separated from each other, the slide cover 3 can be moved from the retracted position to the extended position, and when the slide cover 3 is moved to the extended position, the shutter 31 can be replaced, thereby completing switching of different chip identification resets. Thus, by providing latch hook structure 4 including first latch hook component 41 and second latch hook component 42, slider 3 can be well maintained in the retracted position when burning the chip; when the baffle 31 needs to be replaced, external force is applied to the first latch hook component 41, so that the first latch hook component 41 and the second latch hook component 42 can be disengaged, and the unlocking is convenient.

Further, referring to fig. 2 to 4, the first latch member 41 includes a first latch hook member 411 and a first elastic member 412. One end (e.g., left end in fig. 3) of the first latch hook member 411 is pivotably connected to the housing 1, the other end (e.g., right end in fig. 3) of the first latch hook member 411 is rotatable about the above one end thereof and has a first hook portion 4111 bent away from the center of the housing 1, and the first elastic member 412 is stopped between the first latch hook member 411 and the housing 1. The second latch hook member 42 has a second hook 421 bent toward the center of the housing 1, and the first elastic member 412 pushes the first latch hook 411 toward a direction away from the center of the housing 1 when the slide cover 3 is in the retracted position so that the second hook 421 is kept hooked with the first hook 4111.

For example, in the examples of fig. 2 to 4, the left end of the first latch member 411 is pivotally connected to the housing 1, specifically, the housing 1 may be provided with a first positioning column extending upward from the bottom wall of the housing 1, the left end of the first latch member 411 is formed with a pivot hole correspondingly engaged with the first positioning column, and the left end of the first latch member 411 is made to be pivotable relative to the housing 1 by making the pivot hole of the left end of the first latch member 411 fit over the first positioning column. The right end of the first latch hook member 411 is rotatable around the left end of the first latch hook member 411, the right end of the first latch hook member 411 is provided with a first hook portion 4111 bent away from the center of the housing 1, a first elastic member 412 is arranged between the first latch hook member 411 and the housing 1, the left end of the second latch hook member 42 is provided with a second hook portion 421 capable of being hooked with the first hook portion 4111, and the second hook portion 421 is bent towards the center of the housing 1. When the sliding cover 3 is located at the retracted position, the first elastic member 412 is in a compressed state, and the elastic force generated by the first elastic member 412 pushes the first latch hook member 411 in a direction away from the center of the housing 1, so that the first hook portion 4111 and the second hook portion 421 are always kept hooked; when a force is applied to the first latch hook member 411 in a direction toward the center of the housing 1, the first hook member 4111 rotates about the left end of the first latch hook member 411 in a direction toward the center of the housing 1, thereby disengaging from the second hook member 421 and allowing the second latch hook member 42 to move toward the extended position. Therefore, through the arrangement, the structure of the first latch assembly 41 is simple and reliable, and the sliding cover 3 can be effectively kept at the retraction position when the chip is burnt.

Further, as shown in fig. 2 to 4, a receiving cavity 11 with one open side is formed on the housing 1, a limiting member 111 is disposed at the one side in the receiving cavity 11, the first latch hook member 411 and the first elastic member 412 are both disposed in the receiving cavity 11, and the limiting member 111 is disposed at a side of the first latch hook member 411 away from the first elastic member 412 in the rotation direction, so as to limit the other end of the first latch hook member 411 to continue to rotate out of the receiving cavity 11 and limit the second latch hook member 42 to continue to move towards the position away from the extending position. Here, it should be noted that the direction "outside" may be understood as a direction away from the center of the accommodating chamber 11, and the opposite direction is defined as "inside", i.e., a direction toward the center of the accommodating chamber 11.

For example, in the example of fig. 2 to 4, when the right end of the first latch hook member 411 rotates away from the center of the housing 1, the stopper 111 may act as a stop for the right end of the first latch hook member 411 to prevent the right end of the first latch hook member 411 from rotating out of the accommodating cavity 11; when the second latch hook member 42 moves to the retracted position, the stopper 111 can also act as a stop for the second latch hook member 42, preventing the second latch hook member 42 from moving further to the left. Therefore, the limiting member 111 has a good limiting effect on the first latch hook member 411 and the second latch hook member 42, and when the sliding cover 3 is located at the retraction position, the first hook portion 4111 and the second hook portion 421 can be well hooked, so that the structural stability of the latch hook structure 4 is improved. Moreover, by providing the housing chamber 11, the size of the universal reset identifier 100 can be further reduced to facilitate the operator to hold the programming chip.

Alternatively, the first elastic member 412 is a spring or the like. Therefore, because the elastic force of the spring is stronger, when the slide cover 3 is located at the retraction position, the spring can push the first latch hook 411 by using the elastic force of the spring to make the second hook 421 and the first hook 4111 always keep hooked, so that the chip can be burned more reliably.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the first latch hook assembly 41 may further include a third latch hook member (not shown), one end of which is fixed to the housing 1, and the other end of which is deformable with respect to the above-mentioned one end thereof. Therefore, the sliding cover 3 can be kept at the retracted position and can move between the retracted position and the extended position, so that the burning of the chip and the switching of different chip identification and resetting can be well completed.

In a further embodiment of the present invention, referring to fig. 2 and 4 in combination with fig. 1 and 3, at least one second elastic member 5 extending along the moving direction of the sliding cover 3 is disposed between the housing 1 and the sliding cover 3, and the sliding cover 3 moves to the extended position under the elastic force of the second elastic member 5 when the first latch component 41 is disengaged from the second latch hook component 42. For example, in the example of fig. 2 and 4, two second elastic members 5 are provided at intervals between the housing 1 and the sliding cover 3, the two second elastic members 5 extend in the moving direction of the sliding cover 3 (for example, the left-right direction in fig. 1), when the sliding cover 3 is located at the retracted position, the first latch member 41 and the second latch member 42 are latched, and the two second elastic members 5 are in a compressed state; when the first latch hook assembly 41 is disengaged from the second latch hook member 42, the elastic potential energy of the two second elastic members 5 is converted into the kinetic energy of the sliding cover 3, and the sliding cover 3 is pushed to move from the retracted position to the extended position. Therefore, the sliding cover 3 can be more easily moved from the retracted position to the extended position by arranging the second elastic piece 5, so that the switching of different chip identification resetting is realized. Optionally, the second elastic member 5 is a spring. But is not limited thereto.

Two second elastic members 5 are shown in fig. 2 and 4 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solutions of the present application that the solutions can be applied to other numbers of second elastic members 5, which also fall within the protection scope of the present invention.

Alternatively, the number of the latch hook structures 4 may be two, and the two latch hook structures 4 are symmetrically arranged along the longitudinal direction of the housing 1. Therefore, the sliding cover 3 can be better kept at the retraction position by arranging the two locking hook structures 4, and the sliding cover 3 can move between the retraction position and the extension position more stably and reliably.

In some embodiments of the present invention, referring to fig. 2 in combination with fig. 1, 3 and 4, two sliding grooves 33 that are relatively open are respectively formed on two side walls of the sliding cover 3 that are opposite to each other, and two ends of the baffle 31 are respectively fitted in the two sliding grooves 33. Therefore, the two sliding grooves 33 can position and guide the baffle 31, so that the baffle 31 can be more easily put into the sliding cover 3 and can be well kept in the sliding cover 3.

Further, as shown in fig. 1 to 3, the slide cover 3 is formed with an opening 34 therethrough, the opening 34 communicates with both the slide grooves 33, and the shutter 31 is fitted into both the slide grooves 33 through the opening 34. For example, in the example of fig. 1 and 2, the opening portion 34 is formed at the top of the slide cover 3, the two slide grooves are respectively located at both sides of the slide cover 3 in the width direction, the opening portion 34 may penetrate the slide cover 3 in the thickness direction of the slide cover 3, and both ends of the opening portion 34 may respectively communicate with the two slide grooves 33. When the shutter 31 is mounted, it can pass through the opening 34 from top to bottom, and both ends of the shutter can be fitted into the two slide grooves 33. Therefore, when the baffle 31 is replaced, the baffle 31 can be fitted into the chute 33 through the opening 34, and the baffle 31 can be taken out from the chute 33 through the opening 34, thereby facilitating replacement of the baffle 31.

Alternatively, referring to fig. 1 to 3, at least one escape opening 341 that is recessed toward a direction away from the baffle 31 is formed on a sidewall of the opening portion 34. Therefore, by arranging the avoiding opening 341, the user can take the baffle 31 out of the sliding cover 3 or put the baffle 31 into the sliding cover 3 through the avoiding opening 341, and the operation is more convenient.

Alternatively, referring to fig. 2 in combination with fig. 1, 3 and 4, the sliding groove 33 is provided at an end of the sliding cover 3 away from the housing 1. Therefore, through the arrangement, the chip is more convenient to burn and write.

In some embodiments of the present invention, referring to fig. 1 and 2, at least one through hole 12 is formed on the housing 1, and a light-transmitting sheet 121 is disposed at the through hole 12. Wherein, the light-transmitting sheet 121 may be provided with an indicator light. For example, three indicator lights may be disposed on the light-transmitting sheet 121, and the three indicator lights may be respectively used to indicate that the reset identifier 100 is successfully connected to the bluetooth, successfully reset, and successfully burn the chip.

In some embodiments of the present invention, as shown in fig. 1 and 2, the housing 1 includes a first sub-housing 13 and a second sub-housing 14, and the first sub-housing 13 and the second sub-housing 14 are provided in a thickness direction of the housing 1 and detachably mounted to each other. For example, in the example of fig. 1 and 2, the first sub-housing 13 and the second sub-housing 14 are provided in the thickness direction of the housing 1, an accommodation space is defined between the first sub-housing 13 and the second sub-housing 14 for accommodating the main board 2 and the like, and the first sub-housing 13 and the second sub-housing 14 are detachably mounted to each other. From this, casing 1's simple structure, loading and unloading are convenient, and make things convenient for the maintenance of spare part in casing 1.

In some embodiments of the present invention, as shown in fig. 1 to 3, the sliding cover 3 includes a sliding cover housing 36 and a sliding cover portion 35, one side (for example, a lower side in fig. 2) in a thickness direction of the sliding cover housing 36 is open, the sliding cover portion 35 is covered on the one side of the sliding cover housing 36, and the sliding cover housing 36 and the sliding cover portion 35 are detachably mounted. For example, in the example of fig. 2, the lower side of the sliding cover housing 36 is open, a second positioning post with a hollow interior may be disposed on the sliding cover portion 35, a positioning section corresponding to the second positioning post is disposed on the sliding cover housing 36, and the positioning section on the sliding cover housing 36 is fitted in the hole of the second positioning post, so that the sliding cover portion 35 is disposed on the lower side of the sliding cover housing 36. Therefore, through the arrangement, the slide cover 3 is convenient to disassemble and assemble, and the slide cover part 35 can support the baffle 31, so that the structure of the whole universal reset recognizer 100 is more stable.

In the above process, the identification pins 21 may be retractable identification pins 21, and when different chips are to be programmed, the corresponding baffle 31 may be replaced, so that the corresponding identification pins 21 extend out of the pin holes 32, and the rest identification pins 21 are blocked by the baffle 31, thereby implementing programming of different types of chips. Of course, the identification pins 21 may be driven by a motor to extend and retract, and when different chips are programmed, the corresponding identification pins 21 may be driven by the motor to extend the identification pins 21 corresponding to the chips from the pin holes 32, so as to also program different types of chips. Therefore, through the arrangement, the switching of different chip identification resets can be realized, and the whole universal reset identifier 100 is simple in structure, small in size and space-saving.

Optionally, a wireless communication device (not shown) may be disposed on the motherboard 2. For example, a wireless bluetooth device or the like may be provided on the main board 2. Therefore, the wireless communication device is connected with the host, so that the whole universal reset recognizer 100 is free from the constraint of wires, the universal reset recognizer 100 is more portable, and the convenience of the universal reset recognizer 100 is greatly improved.

Alternatively, the main board 2 may be provided with a battery 22. Therefore, the battery 22 can supply power to the whole universal reset recognizer 100, thereby prolonging the service time of the universal reset recognizer 100 and realizing the switching of various chip recognition resets.
