All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The core of the invention is to provide a novel collision detection device, which utilizes a conductive sticker 12 and a detection head 11 to detect whether two adjacent detection components collide, the detection components collide to enable the detection head 11 to contact the conductive sticker 12, and then a circuit is conducted to send out a trigger signal, and the collision condition and the position are detected according to the trigger signal.
Example 1
Fig. 1 is a schematic structural diagram of a novel collision detecting device according to an embodiment of the present invention, which includes a processor 1, a connector 3, an indicator light 2, and a conductive sticker 12.
At least one interface 4 is arranged on the connector 3, each interface 4 comprises two joints 5, each joint 5 is connected with a signal wire 8, the head end of the signal wire 8 leaks out of the metal head 10, and the metal head 10 of the two signal wires 8 of each interface 4 forms a detection head 11. Normally, the metal heads 10 of the two signal wires 8 are not in contact with each other, the corresponding interface 4 is not conductive, and if two detection components collide, the metal heads 10 of the two signal wires 8 are conductive through the conductive adhesive paper 12, and the corresponding interface 4 is conductive. In order to ensure that the metal heads 10 of the two signal wires 8 are not contacted under normal conditions, for the two signal wires 8 of one detection head 11, the two signal wires 8 are fixed near the head end by using an insulating colloid 9, so that the two metal heads 10 are relatively close in distance but are not contacted.
The probe 11 is attached to a first detecting member 15, and the conductive sticker 12 is attached to a second detecting member 16 adjacent to the first detecting member 15; and each detecting head 11 corresponds to one conductive sticker 12, the position of the detecting head 11 is matched with the position of the conductive sticker 12, if a part of the first detecting part 15 collides with the second detecting part 16, the corresponding detecting head 11 at the part contacts with the corresponding conductive sticker 12, and then the corresponding interface 4 on the connector 3 is connected. Fig. 2 is a schematic diagram of the attaching structure of the conductive adhesive paper 12 and the probe 11 in the present embodiment, in which two detection parts are adjacent, and fig. 3 is a schematic diagram of the relative positions of two detection parts, in which the conductive adhesive paper 12 and the probe 11 are disposed opposite to each other, and in the reliability test, the two detection parts may collide with each other, so that the probe 11 contacts the conductive adhesive paper 12. The conductive sticker 12 is composed of an insulating portion and a conductive portion, and specifically includes a lower insulating sticker 13 and an upper conductive sticker 14, where the area of the conductive sticker 14 is smaller than that of the insulating sticker 13, so that the insulating sticker 13 is attached to the detecting component, and the performance of the detecting component is not affected.
In order to realize collision indication, the number of the indicator lamps 2 is consistent with that of the interfaces 4, and one indicator lamp 2 corresponds to one interface 4; the connector 3 and the indicator lamp 2 are respectively and electrically connected with the processor 1; when the first detecting part 15 collides with the second detecting part 16 to switch on the corresponding interface 4, the processor 1 controls the state of the corresponding indicator lamp 2 according to the switch-on signal. For example, the on state of one interface 4 is indicated by one red LED lamp and one green LED lamp together, and when the interface 4 is not on (i.e., no collision occurs), the green light is on, and when the interface 4 is on (i.e., collision occurs), the red light is on.
According to the novel collision detection device provided by the embodiment of the invention, the conductive sticker 12 and the detection head 11 are arranged, the conductive sticker 12 and the detection head 11 are oppositely arranged on two adjacent detection components, if the two detection components collide, the detection head 11 can be contacted with the conductive sticker 12, so that the interface 4 is conducted, the state of the indicator lamp 2 is controlled by the processor 1 to indicate that a collision condition occurs, and the collision position can be determined according to the position of the detection head 11.

The trigger circuit includes: the comparator U1, the first pull-up resistor R1, the first pull-down resistor R2, the second pull-up resistor R3 and the second pull-down resistor R4.
The first end of the first pull-up resistor R1 is connected with the power supply voltage, and the second end is grounded through the first pull-down resistor R2 and is connected to the positive input end of the comparator U1.

It can be understood that the comparator outputs a corresponding low level and a corresponding high level according to the high voltage of the positive input terminal and the negative input terminal, when the voltage of the positive input terminal is lower than the voltage of the negative input terminal, the comparator outputs a low level, and when the voltage of the positive input terminal is higher than the voltage of the negative input terminal, the comparator outputs a high level. Based on this, the resistance of each resistor is designed, for example, the first pull-up resistor R1, the first pull-down resistor R2, and the second pull-up resistor R3 are all 4.7K ohms, and the second pull-down resistor R4 is 100 ohms. When the circuit is powered on and collision does not occur, the interface 4 is not connected and is IN an off state, the power supply voltage is input into-IN of the comparator U1, the power supply voltage is input into +IN of 1/2, at the moment, the power supply voltage of each path of comparator U1 is-IN > +IN, the comparator U1 outputs a low level, and at the moment, the processor 1 can light a green light. When the probe 11 IN one of the paths 4 is turned on, i.e. the interface 4 is turned on, the-IN input of the path comparator U1 is the voltage division of the second pull-down resistor R4 of 100 ohms, the +in input is the power supply voltage of 1/2, and the path-IN > + IN. comparator U1 outputs a high level, at this time, the processor 1 will turn on the red light of the path.
In a specific embodiment, for convenience of plugging, the connector 3 includes a socket 6 and a plug 7 (as shown in fig. 1), where a signal line 8 is led out from the plug 7, and the plug 7 is pluggable to the socket 6. It will be appreciated that the connection 5 of the connection resistor in the trigger circuit is the connection 5 on the socket 6.

Correspondingly, a power module for supplying power to the device is also arranged in the assembly shell 17, and a key switch 18 is arranged on the assembly shell 17. Wherein, the power module can adopt a battery. When in use, double-sided adhesive tape is adhered to the bottom of the assembly shell 17 and fixed inside the server case.
In order to improve the positioning of the collision part more accurately, the contact degree of the two detection parts is judged, when the collision detection is carried out, a plurality of detection heads 11 can be arranged, and the detection heads 11 are attached to the first detection part 15 in a linear arrangement mode, for example, 5 detection heads 11 are all arranged, wherein the first 3 detection heads 11 are conducted, the second 2 detection heads 11 are not conducted, the fact that the collision exists in the length range of the first 3 detection heads 11 is indicated, so that the collision part is positioned, and the contact degree is judged.
In the implementation, the processor 1 may adopt an MCU, and of course, the user may select other chips according to specific situations and actual requirements, and the selection of a specific chip of the processor 1 does not affect the implementation of this embodiment.
