Description

Technical Field

[0001] The present application belongs to the technical field of engine testing, and specifically relates to a power supply module and a temperature measurement mechanism. Background Art

[0002] The piston is an important component of the combustion chamber, and the temperature of the piston affects the performance indicators of the engine. Therefore, the piston temperature needs to be dynamically measured during the experiment in order to further optimize the design of the piston based on the piston temperature.

[0003] Before measuring the piston temperature, a temperature measuring mechanism needs to be installed on the connecting rod of the engine. The existing temperature measuring mechanism includes a temperature sensing module, a battery, a spring and a fixed shell, wherein the battery, the spring and the fixed shell together constitute a power supply module for powering the temperature sensing module. However, since the temperature measuring mechanism needs to be installed on the engine connecting rod in advance, that is, the piston temperature measuring mechanism is installed in the internal space of the engine, this results in that the staff can no longer operate and maintain the temperature measuring mechanism. Therefore, when the engine begins to be assembled, the temperature measuring mechanism needs to be electrically conductive, that is, the power supply module needs to power the temperature sensing module, and the battery begins to be in a discharge state. However, since the entire engine assembly process takes several days, but the battery power is limited, which in turn affects the effective working time of the temperature measuring mechanism.

[0004] In order to increase the effective working time of the temperature measuring mechanism, our company has previously applied for a piston temperature measuring mechanism (announcement number CN112146884B), which realizes power off to the power supply module before the engine is assembled by arranging a slider and a breakable first connecting shaft in the fixed sleeve. When the engine is working, the connecting rod drives the temperature measuring mechanism to move, and the slider generates up and down inertial forces. When the acceleration of the connecting rod reaches a preset value, the first connecting shaft breaks under the inertial force of the slider, thereby making the battery and the temperature sensing module electrically conductive, so that the temperature sensing module can dynamically measure the temperature of the piston.

[0005] However, since the power supply module and the temperature sensing module are disconnected by limiting the position of the battery through a breakable first connecting shaft, and the first connecting shaft cannot be restored once it breaks, the power supply module cannot be stopped once it starts supplying power to the temperature sensing module, causing the power supply module to become a disposable consumable, thereby increasing the cost of piston temperature measurement. Utility Model Content

[0006] The present application provides a power supply module and a temperature measurement mechanism, so that the power supply module can be recycled and the cost of piston temperature measurement can be reduced.

[0007] The technical solution adopted in this application is:

[0008] A power supply module comprises a fixed sleeve having a accommodating cavity and a battery arranged inside the accommodating cavity, and also comprises a sliding block arranged in the accommodating cavity and capable of moving relative to the battery, a conductive block arranged on one end of the sliding block close to the battery, a conduction driving member arranged in the accommodating cavity and acting on the sliding block, and a power-off driving member arranged in the fixed sleeve and acting on the sliding block or the conduction driving member, wherein when the conduction driving member is working and the power-off driving member stops working, the sliding block moves in a direction close to the battery so that the conductive block contacts the battery and is electrically conductive, and when the power-off driving member is working, the sliding block moves in a direction away from the battery so that the conductive block is separated from the battery and the electrical conduction is disconnected.

[0009] By adopting the above technical solution, when the temperature of the piston is dynamically measured using the temperature measuring mechanism equipped with the power supply module in the present application, the temperature measuring mechanism is first installed on the connecting rod, and when the engine is assembled and the temperature of the piston is dynamically measured, the power-off drive stops working, and the conduction drive starts working at this time, and drives the sliding block toward the direction close to the battery, so that the sliding block drives the conductive block to move, and then the conductive block contacts the battery and is electrically connected with the battery, and the power supply module is electrically connected with the temperature sensing module, and the temperature sensing module starts working and measures the temperature of the piston. After the temperature measurement of the piston is completed, the engine is disassembled, and the temperature measuring mechanism is removed from the connecting rod, and then the power-off drive starts working, and the sliding block drives the conductive block to move in the direction away from the battery, so that the conductive block is separated from the battery and the electrical conduction is disconnected, so as to realize the power off of the temperature measuring mechanism, so as to increase the effective working time of the temperature measuring mechanism, and then the temperature measuring mechanism can be recycled. At the same time, when the temperature measuring mechanism disassembled from the connecting rod has low power, the battery can be charged to ensure the effective working time of the temperature measuring mechanism.

[0010] To sum up, the power supply module in the present application realizes reciprocating electrical conduction and disconnection, so that the power supply module can be recycled, and then the temperature measuring mechanism equipped with the power supply module in the present application can be recycled, thereby reducing the generation of consumables, thereby reducing the cost of piston temperature measurement, and greatly improving the company's benefits.

[0011] Optionally, the accommodating cavity includes a first cavity and a second cavity connected to the first cavity, the first cavity and the second cavity are arranged at an angle, the battery, the sliding block and the conductive block are all arranged in the first cavity, the power-off drive component is arranged at the end of the second cavity, the conduction drive component is arranged in the second cavity, and the conduction drive component includes a transmission part and an elastic part for applying a driving force to the transmission part toward the direction close to the first cavity, the transmission part is provided with a transmission inclined surface at one end close to the sliding block, and the sliding block is provided with a matching inclined surface that cooperates with the transmission inclined surface guide.

[0012] By adopting the above technical solution, after the power-off drive stops working, the transmission part moves towards the direction close to the sliding block under the action of the elastic part, so that the transmission slope and the matching slope slide relative to each other, and the sliding block moves towards the direction close to the battery under the action of the transmission slope and the matching slope, so that the conductive block contacts the battery, so that the power supply module supplies power to the temperature sensing module. When the temperature measuring mechanism is powered off, the power-off drive starts to work, and then the transmission part moves in the direction away from the sliding block under the action of the power-off drive, and the transmission slope and the matching slope slide relative to each other, so that the sliding block moves in the direction away from the battery, so that the conductive block is separated from the battery, and the electrical conduction between the conductive block and the battery is disconnected, and the power supply to the temperature sensing module is stopped, so as to extend the effective working time of the temperature measuring mechanism. In addition, the first cavity and the second cavity are arranged at an angle to reduce the size of the fixed sleeve in a single direction, and can also reduce the influence of inertial force on the contact stability between the conductive block and the battery, so as to ensure the electrical conduction effect between the conductive block and the battery, and then ensure the stability of the power supply module when supplying power to the temperature sensing module.

[0013] Optionally, the conductive driving member has an installation cavity with a cavity opening located on its side surface, a locking pin and a locking elastic member for driving the locking pin to move toward the outside of the installation cavity are provided in the installation cavity, the fixing sleeve is provided with a locking hole corresponding to the locking pin, when the locking pin is plugged into the locking hole, the conductive block contacts the battery and is electrically conductive, the locking hole has a first opening located on the outer wall of the fixing sleeve, an unlocking pin capable of relative movement with the locking hole is provided at the first opening, so that when the unlocking pin moves toward the inside of the fixing sleeve, pressure is applied to the locking pin toward the inside of the installation cavity.

[0014] By adopting the above technical solution, the transmission part moves under the action of the elastic part, so that after the conductive block contacts the battery, the locking pin is plugged and matched with the locking hole under the action of the locking elastic part, so that the plugging and matching of the locking pin and the locking hole can realize the locking of the conductive drive part, thereby increasing the connection stability between the conductive block and the battery, so as to avoid the situation that the conductive block may be separated from the battery under the action of inertia when the connecting rod moves up and down, thereby ensuring the power supply stability of the power supply module to the temperature sensing module, so as to ensure the stability of the piston temperature measurement. When the temperature measuring mechanism removed from the connecting rod is powered off, the staff only needs to apply pressure to the unlocking pin toward the inside of the locking hole, so that the unlocking pin applies pressure to the locking pin toward the inside of the installation cavity, thereby separating the locking pin from the locking hole, and at the same time, the power-off drive works to make the sliding block move in the direction away from the battery, so that the conductive block is separated from the battery, so as to realize the power off of the temperature measuring mechanism.

[0015] Optionally, the fixing sleeve has a accommodating cavity with a cavity opening located in the cavity wall of the accommodating cavity, a limit pin and a limit elastic member acting on the limit pin are arranged in the accommodating cavity, an unlocking drive member acting on the limit pin is arranged outside the accommodating cavity, and the conductive drive member is provided with a limit hole corresponding to the limit pin, when the limit pin is plugged into the limit hole, the conductive block is separated from the battery, when the limit elastic member works and the unlocking drive member stops working, the limit pin moves toward the direction close to the limit hole, and when the unlocking drive member works, the limit pin moves toward the direction away from the limit hole.

[0016] By adopting the above technical solution, when the temperature sensing module is powered, the unlocking drive starts to work, so that the limit pin moves in a direction away from the limit hole under the action of the unlocking drive, and then the limit pin is separated from the limit hole, thereby unlocking the conduction drive, and then the conduction drive drives the sliding block, so that the sliding block drives the conductive block to move in a direction close to the battery, so that the conductive block contacts and electrically conducts with the battery, so as to power the temperature sensing module. When the temperature sensing module is powered off, the power-off drive works, and then the sliding block moves in a direction away from the battery under the action of the power-off drive, and the conduction drive moves at the same time. When the limit hole moves to the position where the limit pin is located, the limit pin enters the limit hole under the action of the limit elastic member, and the power-off drive can stop working at this time, so that the conduction drive is limited to a state where the conductive block and the battery cannot be conducted under the plug-in cooperation of the limit pin and the limit hole.

[0017] By arranging the limit pin, the limit elastic member and the unlocking drive member, the working time of the power-off drive member is shortened, thereby achieving the effect of reducing the energy consumption of the temperature measuring mechanism.

[0018] Optionally, an extension portion is provided on the outside of the fixing sleeve corresponding to the accommodating cavity, and the accommodating cavity extends to the interior of the extension portion, and the limit pin has a positioning cavity with a cavity opening located on its side surface, and a positioning pin and a positioning elastic member for driving the positioning pin to move toward the outside of the installation cavity are provided in the positioning cavity, and a positioning hole is provided on the extension portion corresponding to the positioning pin, and when the positioning pin is plugged into the positioning hole, the limit pin and the limit hole are released from the plug-in fit, and the positioning hole has a first hole located on the outer wall of the extension portion, and a driving pin capable of relative movement with the positioning hole is provided at the first hole, so that when the driving pin moves toward the inside of the extension portion, pressure is applied to the positioning pin toward the inside of the positioning cavity.

[0019] By adopting the above technical solution, when the limit pin moves in the direction away from the limit hole under the action of the unlocking drive member, the limit pin drives the positioning pin to move. When the limit pin is separated from the limit hole and the positioning pin moves to the position of the positioning hole, the positioning pin enters the positioning hole under the action of the positioning elastic member and is plugged into the positioning hole, so that the limit pin remains stationary under the action of the plug-in cooperation between the positioning pin and the positioning hole, that is, the limit pin is locked. At this time, there is a gap between the limit pin and the conductive drive member, so as to shorten the operation of the unlocking drive member and reduce the resistance of the conductive drive member during operation, so as to ensure the driving effect of the conductive drive member on the sliding block, and then ensure the electrical conduction effect between the conductive block and the battery.

[0020] When the limit pin is unlocked, pressure is applied to the driving pin toward the inside of the positioning hole through the first hole, so that the driving pin drives the positioning pin to separate the positioning pin from the positioning hole, thereby unlocking the limit pin, and then the limit pin can cooperate with the limit hole to lock the conductive drive component.

[0021] Optionally, an insulating elastic member located between the battery and the sliding block is provided in the accommodating cavity, and when the conductive block contacts the battery, the insulating elastic member undergoes elastic deformation.

[0022] By adopting the above technical solution, when it is necessary to cut off the power to the temperature sensing module, the power-off driving component works, and the sliding block moves in the direction away from the battery under the joint action of the power-off driving component and the insulating elastic component, so that the conductive block is separated from the battery, thereby ensuring that the power supply module and the temperature sensing module are disconnected from the electrical conduction, and at the same time ensuring the stability of the conductive block after the electrical conduction is disconnected from the battery.

[0023] Optionally, the conductive block is provided corresponding to one of the positive electrode and the negative electrode of the battery, and the other of the positive electrode and the negative electrode of the battery and the conductive block are both provided with a conductive wire extending out of the fixing sleeve.

[0024] By adopting the above technical solution, the power supply module is electrically connected to the temperature sensing module through a conductive wire. On the one hand, it is convenient to electrically connect the power supply module to the temperature sensing module. On the other hand, it is also convenient to power the battery, so as to further increase the number of times the power supply module can be recycled, thereby increasing the number of times the temperature measuring mechanism can be recycled, and further reducing the cost of piston temperature measurement.

[0025] Optionally, the conductive block is arranged corresponding to the negative electrode of the battery, and a fixing member for fixing the positive electrode of the battery is arranged in the accommodating cavity.

[0026] By adopting the above technical solution, since the negative electrode of the battery has a larger contact plane than the positive electrode of the battery, and the guide block is arranged corresponding to the negative electrode of the battery, the contact area between the conductive block and the battery can be increased, thereby ensuring the electrical conduction stability between the conductive block and the battery; at the same time, since the positive electrode of the battery has a protruding structure, and the fixing member fixes the positive electrode of the battery, it is possible to achieve the effect of facilitating the fixation of the battery to avoid the movement of the battery in the accommodating cavity, thereby ensuring the separation effect of the conductive block and the battery, that is, ensuring the power-off effect of the power supply module on the temperature sensing module, so as to extend the effective working time of the temperature measuring mechanism.

[0027] Optionally, the power-off driving component is a coil, and the sliding block and / or the power-on driving component is a structure made of magnetic conductive material.

[0028] By adopting the above technical solution, after the temperature measuring mechanism is removed from the connecting rod, the coil is energized to generate a magnetic field. Since the sliding block and / or the conductive driving member are structures made of magnetic conductive materials, the sliding block or the conductive driving member moves toward the direction close to the coil under the action of the magnetic field to separate the conductive block from the battery, thereby cutting off the power to the temperature sensing module and extending the effective working time of the battery.

[0029] The present application also discloses a temperature measuring mechanism, including a temperature sensing module and the power supply module mentioned above, wherein the power supply module is used to supply power to the temperature sensing module.

[0030] By adopting the above technical solution, the temperature measuring mechanism in the present application adopts the above power supply module, thereby having all the advantages of the above power supply module, so that the temperature measuring mechanism can be recycled, reducing the cost of piston temperature measurement and greatly improving the company's benefits.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

The power supply module in the present application includes a fixed sleeve with a accommodating cavity and a battery arranged inside the accommodating cavity, and also includes a sliding block arranged in the accommodating cavity and capable of moving relative to the battery, a conductive block arranged at one end of the sliding block close to the battery, a conduction drive member arranged in the accommodating cavity and acting on the sliding block, and a power-off drive member arranged in the fixed sleeve and acting on the sliding block or the conduction drive member. When the conduction drive member is working and the power-off drive member stops working, the sliding block moves in a direction close to the battery so that the conductive block contacts the battery and is electrically conductive. When the power-off drive member is working, the sliding block moves in a direction away from the battery so that the conductive block is separated from the battery and the electrical conduction is disconnected, thereby enabling the power supply module in the present application to be recycled, so that the temperature measuring mechanism equipped with the power supply module in the present application can be recycled, thereby reducing the generation of consumables, thereby reducing the cost of piston temperature measurement, and greatly improving the company's benefits.

[0033] 2. An insulating elastic part located between the battery and the sliding block is provided in the accommodating cavity in the present application. When the conductive block contacts the battery, the insulating elastic part undergoes elastic deformation. That is to say, when the temperature sensing module needs to be powered off, the power-off driving part works, and the sliding block moves in a direction away from the battery under the joint action of the power-off driving part and the insulating elastic part, so that the conductive block is separated from the battery, thereby ensuring that the power supply module and the temperature sensing module are disconnected from the electrical conduction, and at the same time ensuring the stability of the conductive block after the electrical conduction is disconnected from the battery.

[0047] Reference Figures 1 to 4 A power supply module includes a fixing sleeve 1 having an accommodating cavity, a battery 2 arranged inside the accommodating cavity, a sliding block 3 arranged in the accommodating cavity and capable of moving relative to the battery 2, a conductive block 31 arranged at one end of the sliding block 3 close to the battery 2, a conduction driving member 5 arranged in the accommodating cavity and acting on the sliding block 3, and a power-off driving member 4 arranged in the fixing sleeve 1 and acting on the sliding block 3 or the conduction driving member 5. When the conduction driving member 5 is working and the power-off driving member 4 stops working, the sliding block 3 moves in a direction close to the battery 2 so that the conductive block 31 contacts the battery 2 and is electrically conductive. When the power-off driving member 4 is working, the sliding block 3 moves in a direction away from the battery 2 so that the conductive block 31 is separated from the battery 2 and the electrical conduction is disconnected.

[0048] When using the temperature measuring mechanism equipped with the power supply module in this application to dynamically measure the temperature of the piston, the temperature measuring mechanism is first installed on the connecting rod. After the engine is assembled and the temperature of the piston is dynamically measured, the power-off drive 4 stops working, and the power-on drive 5 starts working at this time, and drives the sliding block 3 toward the direction close to the battery 2, so that the sliding block 3 drives the conductive block 31 to move, and then the conductive block 31 contacts the battery 2 and is electrically connected to the battery 2. At this time, the power supply module is electrically connected to the temperature sensing module, and the temperature sensing module starts working and measures the temperature of the piston.

[0049] After the temperature of the piston is measured, the engine is disassembled, and the temperature measuring mechanism is removed from the connecting rod, and then the power-off drive 4 starts to work, and the sliding block 3 drives the conductive block 31 to move away from the battery 2, so that the conductive block 31 is separated from the battery 2 and the electrical conduction is disconnected, so as to realize the power off of the temperature measuring mechanism, increase the effective working time of the temperature measuring mechanism, and then make the temperature measuring mechanism recyclable. At the same time, when the power of the temperature measuring mechanism disassembled from the connecting rod is low, the battery 2 can also be charged to ensure the effective working time of the temperature measuring mechanism.

[0050] To sum up, the power supply module in the present application can realize reciprocating electrical conduction and disconnection, so that the power supply module can be recycled, and then the temperature measuring mechanism equipped with the power supply module in the present application can be recycled, thereby reducing the generation of consumables, thereby reducing the cost of piston temperature measurement, and greatly improving the company's benefits.

[0051] In a preferred embodiment, the battery 2 is rechargeable to increase the number of times the power supply module can be recycled. In other embodiments, the battery 2 can also be non-rechargeable.

[0052] The present application does not specifically limit the structure of the accommodating cavity, and it may adopt any one of the following embodiments:

[0053] Embodiment 1. In this embodiment, referring to Figure 1 and Figure 3 The accommodating cavity includes a first cavity and a second cavity connected to the first cavity, the first cavity and the second cavity are arranged at an angle, the battery 2, the sliding block 3 and the conductive block 31 are arranged in the first cavity, the power-off driving member 4 is arranged at the end of the second cavity, the conduction driving member 5 is arranged in the second cavity, and the conduction driving member 5 includes a transmission part 51 and an elastic part 52 for applying a driving force to the transmission part 51 toward the direction close to the first cavity, the transmission part 51 is provided with a transmission inclined surface 511 at one end close to the sliding block 3, and the sliding block 3 is provided with a matching inclined surface 32 that guides and cooperates with the transmission inclined surface 511.

[0054] It should be noted that, in this embodiment, the power-off driving component 4 acts on the conduction driving component 5, that is, the power-off driving component 4 acts on the transmission part 51; the above-mentioned "the power-off driving component 4 is arranged at the end of the second cavity" means that the power-off driving component 4 is arranged at the end of the second cavity away from the first cavity.

[0055] Specifically, after the power-off drive member 4 stops working, the transmission part 51 moves toward the direction close to the sliding block 3 under the action of the elastic part 52, so that the transmission bevel 511 and the matching bevel 32 slide relative to each other. At the same time, the sliding block 3 moves toward the direction close to the battery 2 under the action of the transmission bevel 511 and the matching bevel 32, so that the conductive block 31 contacts the battery 2, so that the power supply module supplies power to the temperature sensing module.

[0056] When the temperature measuring mechanism is powered off, the power-off drive 4 starts to work, and then the transmission part 51 moves in the direction away from the sliding block 3 under the action of the power-off drive 4, and the transmission inclined surface 511 and the matching inclined surface 32 slide relative to each other, so that the sliding block 3 moves in the direction away from the battery 2, so that the conductive block 31 is separated from the battery 2, and the electrical conduction between the conductive block 31 and the battery 2 is disconnected, and at the same time, the power supply to the temperature sensing module is stopped, so as to extend the effective working time of the temperature measuring mechanism.

[0057] In addition, since the first cavity and the second cavity are arranged at an angle, the size of the fixing sleeve 1 in a single direction is reduced, and the influence of the inertial force on the contact stability between the conductive block 31 and the battery 2 can be reduced, so as to ensure the electrical conduction effect between the conductive block 31 and the battery 2, and further ensure the stability of the power supply module when supplying power to the temperature sensing module.

[0058] The present application does not specifically limit the angle between the first cavity and the second cavity. Preferably, refer to Figure 1 and Figure 3 The central axis of the first cavity and the central axis of the second cavity are arranged at an angle of 90 degrees to further achieve the effect of reducing the size of the fixing sleeve 1.

[0059] Better, refer to Figure 1 and Figure 3 The transmission part 51 is a rod-shaped structure set in the second cavity, and the circumferential surface of the transmission part 51 contacts and cooperates with the cavity wall of the second cavity to increase the stability of the transmission part 51 during movement, thereby ensuring the driving effect of the transmission part 51 on the sliding block 3.

[0060] The present application does not specifically limit the structure of the elastic portion 52. Preferably, refer to Figure 1 and Figure 3 The elastic part 52 is a spring disposed on the side of the transmission part 51 away from the sliding block 3 to increase the driving effect of the elastic part 52 on the transmission part 51, thereby increasing the electrical conduction stability between the conductive block 31 and the battery 2. In other embodiments, the elastic part 52 can also be an elastic sheet or an elastic column with a hollow interior disposed on the side of the transmission part 51 away from the sliding block 3.

[0061] In a preferred embodiment, referring to Figure 2 and Figure 4The conductive driving member 5 has an installation cavity 512 with a cavity opening located on its side, a locking pin 513 and a locking elastic member 514 for driving the locking pin 513 to move toward the outside of the installation cavity 512 are arranged in the installation cavity 512, and a locking hole 11 is arranged on the fixing sleeve 1 corresponding to the locking pin 513. When the locking pin 513 is plugged into the locking hole 11, the conductive block 31 contacts the battery 2 and is electrically conductive, and the locking hole 11 has a first opening located on the outer wall of the fixing sleeve 1, and an unlocking pin 111 capable of relative movement with the locking hole 11 is arranged at the first opening, so that when the unlocking pin 111 moves toward the inside of the fixing sleeve 1, pressure is applied to the locking pin 513 toward the inside of the installation cavity 512.

[0062] Preferably, the mounting cavity 512 is provided in the transmission part 51, and the transmission part 51 has a first state and a second state. When the transmission part 51 is in the first state, the conductive block 31 contacts the battery 2 and is electrically conductive. When the transmission part 51 is in the second state, the conductive block 31 is separated from the battery 2 and the electrical conduction is disconnected. The locking hole 11 also has a second opening opposite to the first opening, and the second opening is located on the cavity wall of the second cavity.

[0063] Specifically, the transmission part 51 moves under the action of the elastic part 52, so that after the transmission part 51 moves to the first state, that is, after the conductive block 31 contacts the battery 2, the locking pin 513 is plugged into and matched with the locking hole 11 under the action of the locking elastic member 514, so that the plug-in cooperation between the locking pin 513 and the locking hole 11 realizes the locking of the transmission part 51, and then increases the connection stability between the conductive block 31 and the battery 2, so as to avoid the situation that the conductive block 31 may be separated from the battery 2 due to the action of inertia when the connecting rod moves up and down, thereby ensuring the power supply stability of the power supply module to the temperature sensing module, so as to ensure the stability of the piston temperature measurement.

[0064] When powering off the temperature measuring mechanism removed from the connecting rod, the staff only needs to apply pressure to the unlocking pin 111 toward the inside of the locking hole 11 through the first orifice, so that the unlocking pin 111 applies pressure toward the inside of the installation cavity 512 to the locking pin 513, and then the locking pin 513 is separated from the locking hole 11, and at the same time the power-off drive 4 works to move the sliding block 3 in the direction away from the battery 2, so that the conductive block 31 is separated from the battery 2, so as to realize powering off of the temperature measuring mechanism.

[0065] The present application does not specifically limit the structure of the locking elastic member 514. Preferably, refer to Figure 2 and Figure 4The locking elastic member 514 is a spring disposed on the side of the locking pin 513 away from the locking hole 11 to ensure the driving effect of the locking elastic member 514 on the locking pin 513, thereby ensuring the connection stability between the locking pin 513 and the locking hole 11, and further ensuring the electrical conduction stability between the conductive block 31 and the battery 2. In other implementation examples, the locking elastic member 514 can also be an elastic sheet or a hollow elastic column disposed on the side of the locking pin 513 away from the locking hole 11.

[0066] In a preferred embodiment, referring to Figure 2 and Figure 4 The fixing sleeve 1 has a receiving cavity 12 whose cavity opening is located in the cavity wall of the receiving cavity. A limit pin 121 and a limit elastic member 122 acting on the limit pin 121 are arranged in the receiving cavity 12. An unlocking driving member 123 acting on the limit pin 121 is arranged outside the receiving cavity 12. A limit hole 515 is arranged corresponding to the limit pin 121 of the conductive driving member 5. When the limit pin 121 is plugged into the limit hole 515, the conductive block 31 is separated from the battery 2. When the limit elastic member 122 works and the unlocking driving member 123 stops working, the limit pin 121 moves toward the direction close to the limit hole 515. When the unlocking driving member 123 works, the limit pin 121 moves toward the direction away from the limit hole 515.

[0067] Preferably, the limiting hole 515 is provided on the transmission part 51 , and when the transmission part 51 is in the second state, the limiting pin 121 is plugged into and matched with the limiting hole 515 .

[0068] Specifically, when the temperature sensing module is powered, the unlocking drive 123 starts to work, so that the limit pin 121 moves in the direction away from the limit hole 515 under the action of the unlocking drive 123, and then the limit pin 121 is separated from the limit hole 515, thereby unlocking the transmission part 51, and then the compressed elastic part 52 gradually restores its deformation and drives the transmission part 51, so that the transmission part 51 drives the sliding block 3, and the sliding block 3 drives the conductive block 31 to move in the direction close to the battery 2, so that the conductive block 31 contacts the battery 2 and is electrically conductive, so as to realize power supply to the temperature sensing module.

[0069] When the temperature sensing module is powered off, the power-off drive 4 works, and then the transmission part 51 moves toward the second state under the action of the power-off drive 4, so that the sliding block 3 moves in the direction away from the battery 2. When the limiting hole 515 moves to the position of the limiting pin 121, the limiting pin 121 enters the limiting hole 515 under the action of the limiting elastic part 122. At this time, the power-off drive 4 can stop working, so that the transmission part 51 is limited to the second state under the action of the plug-in cooperation between the limiting pin 121 and the limiting hole 515, so as to realize powering off the temperature sensing module.

[0070] By setting the limiting pin 121, the limiting elastic member 122 and the unlocking drive member 123, the transmission part 51 is limited to the second state, shortening the working time of the power-off drive member 4, thereby achieving the effect of reducing the energy consumption of the temperature measuring mechanism.

[0071] The present application does not specifically limit the structure of the limiting elastic member 122. Preferably, refer to Figure 2 and Figure 4 The limiting elastic member 122 is a spring disposed on the side of the limiting pin 121 away from the transmission part 51, so as to increase the driving effect of the limiting elastic member 122 on the limiting pin 121, and at the same time increase the plugging stability of the limiting pin 121 and the limiting hole 515, so as to ensure that the transmission part 51 stays stably in the second state. In other implementation examples, the limiting elastic member 122 can also be an elastic sheet or a hollow elastic column disposed on the side of the limiting pin 121 away from the transmission part 51.

[0072] The present application does not specifically limit the structure of the unlocking driving member 123. Preferably, refer to Figure 1 and Figure 3 The unlocking drive 123 is a coil disposed on the fixed sleeve 1, and the limit pin 121 is a structure made of a magnetic conductive material. For example, the limit pin 121 is made of iron or steel. When the coil is energized, the coil generates a magnetic field, and since the limit pin 121 is made of a magnetic conductive material, the coil generates a magnetic attraction force on the limit pin 121, so that the limit pin 121 moves in a direction away from the limit hole 515, thereby separating the limit pin 121 from the limit hole 515, thereby unlocking the transmission part 51. In other embodiments, the unlocking drive 123 can also be an electromagnet or an electric push rod, and the limit pin 121 is also made of a magnetic conductive material.

[0073] It should be noted that, during the assembly of the engine, two conductive wires are required to be provided for the unlocking drive member 123 so that the conductive wires can power the unlocking drive member 123; and after the unlocking drive member 123 is powered, that is, after the power supply module starts to power the temperature sensing module, the conductive wires can be pulled out of the engine to ensure the normal operation of the temperature measuring mechanism.

[0074] Further, see Figure 1 and Figure 3An extension portion 13 is provided on the outside of the fixing sleeve 1 corresponding to the accommodating cavity 12, and the accommodating cavity 12 extends to the inside of the extension portion 13. The limiting pin 121 has a positioning cavity 124 with a cavity opening located on its side, and a positioning pin 125 and a positioning elastic member 126 for driving the positioning pin 125 to move toward the outside of the installation cavity 512 are provided in the positioning cavity 124. A positioning hole 131 is provided on the extension portion 13 corresponding to the positioning pin 125. When the positioning pin 125 is plugged into the positioning hole 131, the limiting pin 121 is released from the plug-in fit with the limiting hole 515. The positioning hole 131 has a first hole located on the outside of the extension portion 13, and a driving pin 132 capable of relative movement with the positioning hole 131 is provided at the first hole, so that when the driving pin 132 moves toward the inside of the extension portion 13, pressure is applied to the positioning pin 125 toward the inside of the positioning cavity 124.

[0075] The positioning hole 131 further has a second hole opposite to the first hole, and the second hole is located at the cavity wall of the accommodating cavity 12 .

[0076] When the limit pin 121 moves in the direction away from the limit hole 515 under the action of the unlocking drive member 123, the limit pin 121 drives the positioning pin 125 to move. When the limit pin 121 is separated from the limit hole 515 and the positioning pin 125 moves to the position of the positioning hole 131, the positioning pin 125 enters the positioning hole 131 under the action of the positioning elastic member 126 and is plugged into the positioning hole 131, so that the limit pin 121 remains stationary under the action of the plug-in cooperation between the positioning pin 125 and the positioning hole 131. At this time, there is a gap between the limit pin 121 and the conductive drive member 5, so as to shorten the operation of the unlocking drive member 123 while reducing the resistance of the conductive drive member 5 during operation, so as to ensure the driving effect of the conductive drive member 5 on the sliding block 3, and then ensure the electrical conduction effect between the conductive block 31 and the battery 2.

[0077] When the limit pin 121 is unlocked, pressure is applied to the driving pin 132 toward the inside of the positioning hole 131 through the first hole, so that the driving pin 132 drives the positioning pin 125 to separate the positioning pin 125 from the positioning hole 131, thereby unlocking the limit pin 121, and then the limit pin 121 can cooperate with the limit hole 515 to lock the transmission part 51.

[0078] The present application does not specifically limit the structure of the positioning elastic member 126. Preferably, refer to Figure 2 and Figure 4The positioning elastic member 126 is a spring disposed on the side of the positioning pin 125 away from the positioning hole 131, so as to increase the driving effect of the positioning elastic member 126 on the positioning pin 125, thereby ensuring the insertion stability of the positioning pin 125 and the positioning hole 131, so as to increase the stability of the limit pin 121. In other embodiments, the positioning elastic member 126 can also be an elastic sheet or a hollow elastic column disposed on the side of the positioning pin 125 away from the positioning hole 131.

[0079] The present application does not specifically limit the structure of the extension portion 13. Preferably, refer to Figure 1 and Figure 3 The extension part 13 is a tubular structure disposed outside the fixing sleeve 1, so that the inner space of the tubular structure forms the extension part 13 of the accommodating cavity 12. In other embodiments, the extension part 13 can also be a block structure disposed on the fixing sleeve 1, and the accommodating cavity 12 extends to the inside of the block structure.

[0080] In a preferred embodiment, referring to Figure 1 and Figure 3 The fixed sleeve 1 has an operating hole 14 connected to the first cavity, the operating hole 14 is arranged opposite to the second cavity, and a sealing cover 141 is arranged at the operating hole 14, so that when the staff cuts off the power to the temperature measuring mechanism, they can also remove the sealing cover 141, and then pass a rod-shaped structure through the operating hole 14 into the second cavity, so that the rod-shaped structure drives the transmission part 51, so that the transmission part 51 moves to the second state, so as to also complete the power off of the temperature measuring mechanism.

[0081] Embodiment 2: In this embodiment, the accommodating cavity is an integral cavity structure, and the conduction driving member 5 includes an elastic portion 52 disposed on a side of the sliding block 3 away from the battery 2 .

[0082] It should be noted that, in the present embodiment, the power-off driving member 4 acts on the sliding block 3 , that is, when the power-off driving member 4 is working, the sliding block 3 is driven to move in a direction away from the battery 2 .

[0083] That is, the design of the transmission part 51 is cancelled, and the elastic part 52 directly acts on the sliding block 3 to reduce the number of components required for the power supply module, thereby reducing the cost of the power supply module and further reducing the cost of piston temperature measurement.

[0084] Specifically, after the power-off drive 4 stops working, the elastic part 52 drives the sliding block 3 so that the sliding block 3 drives the conductive block 31 to move toward the direction close to the battery 2, so that the conductive block 31 contacts the battery 2 and is electrically conductive, so that the power supply module supplies power to the temperature sensing module.

[0085] When the temperature measuring mechanism is powered, the power-off driving component 4 starts to work, and then the sliding block 3 moves in the direction away from the sliding block 3 under the action of the power-off driving component 4, so that the conductive block 31 is separated from the battery 2, and the electrical conduction between the conductive block 31 and the battery 2 is disconnected, and at the same time, the power supply to the temperature sensing module is stopped, so as to extend the effective working time of the temperature measuring mechanism.

[0086] In a preferred embodiment, referring to Figure 1 and Figure 3 An insulating elastic member 6 is disposed in the accommodating cavity and is located between the battery 2 and the sliding block 3. When the conductive block 31 contacts the battery 2, the insulating elastic member 6 undergoes elastic deformation.

[0087] Specifically, when the temperature sensing module needs to be powered off, the power-off driving component 4 works, and the sliding block 3 moves in the direction away from the battery 2 under the joint action of the power-off driving component 4 and the insulating elastic component 6, so that the conductive block 31 is separated from the battery 2, so as to ensure that the power supply module and the temperature sensing module are disconnected from the electrical conduction, and at the same time ensure the stability of the conductive block 31 after the electrical conduction with the battery 2 is disconnected.

[0088] The present application does not specifically limit the structure of the insulating elastic member 6. Preferably, refer to Figure 1 and Figure 3 The insulating elastic member 6 is an elastic sleeve disposed between the battery 2 and the sliding block 3, and the conductive block 31 is located inside the elastic sleeve to ensure that the conductive block 31 can contact and electrically conduct with the battery 2. In other embodiments, the insulating elastic member 6 can also be a sheet structure made of plastic with a certain elastic force.

[0089] In a preferred embodiment, referring to Figure 1 and Figure 3 The conductive block 31 is provided corresponding to one of the positive electrode and the negative electrode of the battery 2 , and the other of the positive electrode and the negative electrode of the battery 2 and the conductive block 31 are both provided with a conductive wire 7 extending out of the fixing sleeve 1 .

[0090] The power supply module is electrically connected to the temperature sensing module through the conductive wire 7. On the one hand, it is convenient to electrically connect the power supply module to the temperature sensing module. On the other hand, it is also convenient to power the battery 2, so as to further increase the number of times the power supply module can be recycled, thereby increasing the number of times the temperature measuring mechanism can be recycled, and further reducing the cost of piston temperature measurement.

[0091] Better, refer to Figure 1 and Figure 3The conductive block 31 is arranged corresponding to the negative electrode of the battery 2, and a fixing member 8 for fixing the positive electrode of the battery 2 is arranged in the accommodating cavity. Since the negative electrode of the battery 2 has a larger contact plane than the positive electrode of the battery 2, and the conductive block 31 is arranged corresponding to the negative electrode of the battery 2, the contact area between the conductive block 31 and the battery 2 can be increased, thereby ensuring the electrical conduction stability between the conductive block 31 and the battery 2; at the same time, since the positive electrode of the battery 2 has a protruding structure, and the fixing member 8 fixes the positive electrode of the battery 2, it is possible to achieve the effect of facilitating the fixing of the battery 2, so as to avoid the movement of the battery 2 in the accommodating cavity, thereby ensuring the separation effect of the conductive block 31 and the battery 2, that is, ensuring the power-off effect of the power supply module on the temperature sensing module, so as to extend the effective working time of the temperature measuring mechanism.

[0092] The present application does not specifically limit the structure of the fixing member 8. Preferably, the fixing member 8 is a block structure made of insulating material, such as plastic, rubber, etc., and the battery 2 is mounted on the fixing member 8 by gluing or fasteners. In other implementation examples, the fixing member 8 can also be other structures made of insulating materials, as long as the battery 2 can be fixed and insulated.

[0093] The present application does not specifically limit the structure of the power-off driving component 4. Preferably, the power-off driving component 4 is a coil, and the sliding block 3 and / or the conduction driving component 5 are structures made of magnetic conductive materials.

[0094] Specifically, in the above-mentioned embodiment 1, the sliding block 3 and the transmission part 51 of the conductive driving member 5 are structures made of magnetic materials, or the transmission part 51 of the conductive driving member 5 is a structure made of magnetic materials; in the above-mentioned embodiment 2, the sliding block 3 is a structure made of magnetic materials.

[0095] After the temperature measuring mechanism is removed from the connecting rod, the coil is energized to generate a magnetic field. Since the sliding block 3 and / or the conductive driving member 5 are structures made of magnetic conductive materials, the sliding block 3 or the conductive driving member 5 moves toward the direction close to the coil under the action of the magnetic field to separate the conductive block 31 from the battery 2, thereby cutting off the power to the temperature sensing module to extend the effective working time of the battery 2.

[0096] The magnetic conductive material in the present application may be iron, steel or other materials with magnetic conductive properties.

[0097] In other embodiments, the power-off driving member 4 may also be an electromagnet, and the sliding block 3 and / or the conduction driving member 5 may also be a structure made of magnetic conductive material; or, the power-off driving member 4 may be an electric push rod.

[0098] The present application does not specifically limit the material of the fixing sleeve 1 . Preferably, the fixing sleeve 1 is also made of a magnetic conductive material, such as iron or steel, to increase the high temperature resistance of the fixing sleeve 1 .

[0099] The present application also discloses a temperature measuring mechanism, which includes a temperature sensing module and the above-mentioned power supply module, and the power supply module is used to supply power to the temperature sensing module.

[0100] Due to the adoption of the above-mentioned power supply module, it has all the advantages of the above-mentioned power supply module, so that the temperature measuring mechanism can be recycled, the cost of piston temperature measurement is reduced, and the company's benefits are greatly improved.

[0102] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0103] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
