[0039] The terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more, and the meaning of "several" is one or more, unless otherwise specifically limited.

[0040] The top pressure power transmission mechanism and the refrigeration and heating device provided by the utility model will be described.

[0041] AsFigure 5 As shown in the first embodiment of the utility model provides a kind of top pressure power transmission mechanism, including driving rod 25 and pressure head 13, and driving rod 25 one end is equipped with top pressure head 251;Pressure head 13 is equipped with groove 134, and top pressure head 251 can be topped in the bottom of groove 134, to transmit top pressure power to pressure head 13 by driving rod 25.

[0042] The top pressure power transmission mechanism provided in the embodiment can effectively transmit the top pressure power on the driving rod 25 to the pressure head 13 by the cooperation between the top pressure head 251 of the driving rod 25 and the groove 134 on the pressure head 13, and then load the solid-state elastic snap-back heater 10 through the pressure head 13. Since there are no pin shafts and other components in this structure, there will be no fracture failure under the working conditions of large bearing capacity and long-term wear and tear, so that stable transmission of power can be realized. At the same time, since the solid-state elastic snap-back heater 10 will have a rebound force when unloaded, and the pressure head 13 and the driving rod 25 can be reset under the action of the rebound force, this form will not affect the continuous operation of the equipment.

[0043] As shown in the first embodiment of the utility model provides a kind of top pressure power transmission mechanism, including driving rod 25 and pressure head 13, and driving rod 25 one end is equipped with top pressure head 251;Pressure head 13 is equipped with groove 134, and top pressure head 251 can be topped in the bottom of groove 134, to transmit top pressure power to pressure head 13 by driving rod 25. Figures 5 to 7 As shown in the first embodiment of the utility model provides a kind of top pressure power transmission mechanism, including driving rod 25 and pressure head 13, and driving rod 25 one end is equipped with top pressure head 251;Pressure head 13 is equipped with groove 134, and top pressure head 251 can be topped in the bottom of groove 134, to transmit top pressure power to pressure head 13 by driving rod 25.

[0044] The gap between the top pressure head 251 and the mouth of the groove 134 has a swing allowance to allow the driving rod 25 to swing during the transmission of the top pressure power, thereby avoiding wear and tear and splitting of the groove 134.

[0045] The top pressure head 251 is an arc convex structure, and the bottom of the groove 134 is an arc concave structure matched with the top pressure head 251, thereby improving the transmission effect of the top pressure power.

[0046] The bottom of the groove 134 is provided with a blind hole 135. The blind hole 135 can accommodate iron filings, sand particles and other foreign matters generated or accidentally entered into the groove 134 during operation, thereby avoiding the influence of these foreign matters on power transmission. On the other hand, since the gas or liquid in the blind hole 135 is discharged during the top pressure process, the blind hole 135 also functions as a negative pressure suction cup, so that a certain adhesion can be generated between the driving rod 25 and the pressure head 13, which is beneficial to the cooperative movement between them.

[0047] The top pressure head 251 and the groove 134 are filled with lubricating grease. This not only reduces the mechanical wear of the top pressure head 251 and the groove 134, but also reduces the possibility of foreign matter invasion affecting power transmission, and at the same time improves the function of the negative pressure suction cup to facilitate the cooperative movement between the driving rod 25 and the pressure head 13.

[0048] The blind holes 135 are arranged at intervals, so that the aperture of each blind hole 135 can be small enough to avoid affecting the shape of the bottom of the groove 134, thereby ensuring stable power transmission.

[0049] The top pressure head 251 is provided with a wear-resistant sleeve 252 to reduce the wear of the driving rod 25, and a pressure sensor 253 is arranged between the top pressure head 251 and the wear-resistant sleeve 252 to detect the pressure between the driving rod 25 and the pressure head 13, so as to determine whether the power transmission is within the required range, and then adjust the driving rod 25 or the pressure head 13 according to the result.

[0050] The top pressure power transmission mechanism further comprises a rotating main shaft 21, a main shaft support 26 and an eccentric cam 23, the rotating main shaft 21 is used for being connected with the power mechanism 30; the main shaft support 26 is used for being fixed relative to the solid-state elastic clamping regenerator 10 and being rotationally connected with the rotating main shaft 21 to limit the rotating main shaft 21; the eccentric cam 23 is fixed on the rotating main shaft 21 and cooperates with the driving rod 25 to transmit the top pressure power to the driving rod 25.

[0051] As shown in Figures 1 to 4 The utility model discloses a refrigeration and heating device, including power mechanism 30, above-mentioned top pressure power transmission mechanism and solid-state elastic clamping regenerator 10, power mechanism 30 is used to output power;Top pressure power transmission mechanism cooperates with power mechanism 30 to receive the power that power mechanism 30 outputted;Solid-state elastic clamping regenerator 10 is connected with the pressure head 13 of top pressure power transmission mechanism to refrigerate or heat under the driving of pressure head 13.

[0052] Specifically, the power mechanism 30 can be an electric motor, a hydraulic power element, a pneumatic power element, etc.

[0053] By the multi-link transmission mechanism 20, a plurality of solid-state elastic clamping regenerators 10 suitable for the operation of the elastic clamping material can be driven by one set of power mechanism 30 to refrigerate or heat, and then the plurality of solid-state elastic clamping regenerators 10 can be gathered to obtain sufficient heating or refrigeration capacity; in this way, the problem that the material cannot withstand due to the design of the solid-state elastic clamping regenerator 10 being too large can be avoided, and sufficient heating or refrigeration capacity can be provided to meet the demand in actual application.

[0054] In order to facilitate the export of refrigeration or heating capacity, the refrigeration and heating device further comprises a heat-conducting medium collecting mechanism, which is connected with the plurality of solid-state elastic clamping regenerators 10 respectively to supply heat-conducting medium to the plurality of solid-state elastic clamping regenerators 10 respectively, and to collect and exchange heat after the heat-conducting medium exported after being refrigerated or heated by the solid-state elastic clamping regenerators 10.

[0055] The heat conducting medium collecting mechanism can be a pipeline system composed of pipelines, busbars, distributors, pumping assemblies, heat conducting medium storage assemblies, etc. The heat conducting medium collecting mechanism is connected with a heat requiring or cold requiring device such as a heat exchanger to form a cycle to realize heat transfer and circulation.

[0056] As shown in Figure 2 some specific embodiments, the multi-connection transmission mechanism 20 includes a rotating main shaft 21 connected with a power mechanism 30 and a plurality of power output joints arranged at intervals on the rotating main shaft 21 and respectively connected with corresponding solid-state elastic snapback heat exchangers 10. In this way, power can be input to the rotating main shaft 21 by the power mechanism 30, and the power can be input to the corresponding solid-state elastic snapback heat exchangers 10 through the plurality of power output joints.

[0057] The rotating main shaft 21 can be drivingly connected with one power mechanism 30 at one end, or drivingly connected with one power mechanism 30 at each of two ends. That is, one power mechanism 30 can be used to input power, or two power mechanisms 30 can be used to input power, and the two power mechanisms 30 can be of the same power or type, or of different power or type.

[0058] In order to limit the position of the rotating main shaft 21, the multi-connection transmission mechanism 20 further includes a main shaft support 26 fixed on a stable working surface and fixed relative to the solid-state elastic snapback heat exchangers 10, i.e., the positions of the two are fixed relative to each other, and the rotating main shaft 21 is drivingly connected with the main shaft support 26 to ensure stable rotation of the rotating main shaft 21, reduce shaking of the rotating main shaft 21, and avoid the situation that power on the rotating main shaft 21 cannot be transmitted to the solid-state elastic snapback heat exchangers 10.

[0059] In order to ensure the stability of the rotating main shaft 21 while reducing friction loss, the rotating main shaft 21 and the main shaft support 26 are connected through a plurality of second bearings, and the second bearings are located between adjacent power output joints.

[0060] The rotating main shaft 21 and the power output joints can be crank linkage structures or cam structures that can meet the use requirements.

[0061] Specifically, as shown in Figure 3 some specific embodiments, the power output joint includes an eccentric cam 23 fixed on the rotating main shaft 21, a first bearing 22 sleeved on the outer ring of the eccentric cam 23, a ring hoop 24 hooped on the outside of the first bearing 22, and a driving rod 25 fixedly connected at one end with the ring hoop 24 and at the other end with the solid-state elastic snapback heat exchanger 10.

[0062] Through the structure, the rotating power of the rotating main shaft 21 can be converted into the pulling and pressing power on the driving rod 25, the power input into the solid-state elastic card heat accumulator 10 is realized, the elastic card material in the solid-state elastic card heat accumulator 10 is compressed to make the compression phase change and release heat, and the phase change is unloaded to recover heat absorption; and the first bearing 22 can reduce the friction between the eccentric cam 23 and the ring hoop 24.

[0063] The first bearing 22 and the second bearing can be bearing members such as ball bearings, spherical bearings, air bearings and the like, or other members capable of bearing function.

[0064] In a specific embodiment, the first bearing 22 adopts a ball bearing, which can withstand a load of 100,000 N, and the second bearing adopts a spherical bearing, which can withstand a load of 46,713 N.

[0065] Further, the eccentric cam 23 is a disc-shaped wheel structure, and an eccentric shaft hole is arranged in the inside, an inner key groove is arranged on the shaft hole, an outer key groove is arranged at a position corresponding to each eccentric cam 23 of the rotating main shaft 21, and the eccentric cam 23 and the rotating main shaft 21 are fixedly connected through a key strip arranged between the inner key groove and the outer key groove, so as to ensure the stability of the structure.

[0066] The phase angle between the adjacent outer key grooves on the rotating main shaft 21 is 360 / n, that is, all the outer key grooves are uniformly distributed on the lateral projection of the rotating main shaft 21, wherein n is the number of power output joints. In this way, when the rotating main shaft 21 rotates, the torque is approximately the same, so that different solid-state elastic card heat accumulators 10 are rotated in turn, which can not only ensure the stability of the structure and the power output, but also reduce the shaking of the rotating main shaft 21, so as to reduce mechanical wear and noise, and also reduce friction loss and improve energy utilization.

[0067] As shown in FIG. Figure 3 In some specific embodiments, the ring hoop 24 includes a first half ring 241, a second half ring 242 and a half ring fastener 243, the first half ring 241 is fixedly connected with the driving rod 25 through threaded connection, welding or one-piece forming and the like; the second half ring 242 is matched with the first half ring 241 and surrounds the outer ring of the first bearing 22; and the half ring fastener 243 is connected with the first half ring 241 and the second half ring 242 respectively, so as to clamp the first half ring 241 and the second half ring 242 on the outer ring of the first bearing 22, so as to avoid the relative movement between the ring hoop 24 and the outer ring of the first bearing 22, and cause power loss and the like; wherein the inner side of the first half ring 241 and the second half ring 242 is provided with a containing groove for containing the outer ring of the first bearing 22, so as to clamp the first half ring 241 and the second half ring 242 on the outer ring of the first bearing 22 through the half ring fastener 243, so as to avoid the outer ring of the first bearing 22 and the ring hoop 24.

[0068] Specifically, the half-ring fastener 243 can be a threaded fastener, a clamping fastener, or a pin fastener.

[0069] Further, the eccentric cam 23 and the inner ring of the first bearing 22 are in interference fit to avoid relative movement between the eccentric cam 23 and the inner ring of the first bearing 22, thereby avoiding power loss and other problems.

[0070] As shown in the drawings, Figure 3 In some embodiments, the solid elastic return heat exchanger 10 includes a fixed sleeve 11, a plurality of solid elastic material plates 12, a pressure head 13, a plug structure 14, and a medium conveying pipe assembly. The plurality of solid elastic material plates 12 are stacked in the fixed sleeve 11, and each solid elastic material plate 12 includes perforations. The plurality of perforations are stacked to form a flow cavity for the heat-conducting medium to pass through. The pressure head 13 is slidingly arranged at one end of the fixed sleeve 11 and is connected with a driving rod 25 to load or unload the plurality of solid elastic material plates 12 under the driving of the driving rod 25, so that the plurality of solid elastic material plates 12 are deformed to generate heat or cold. The plug structure 14 is plugged at the other end of the fixed sleeve 11 and abuts against the solid elastic material plates 12 to limit the axial movement of the solid elastic material plates 12. The medium conveying pipe assembly is in communication with the flow cavity and is connected with a heat-conducting medium collecting mechanism to input and output the heat-conducting medium.

[0071] It should be noted that the shape of the pressure head 13 is the same as the cross-sectional shape of the solid elastic material plate. In this way, when the pressure head applies stress to the solid elastic material plate, the force acting on the protrusions can be avoided, thereby increasing the energy consumption ratio of the cooling and heating device. In order to increase the loading strength, the pressure head can be made of high-strength ceramic or tungsten steel.

[0072] The shape and number of perforations can be selected as needed. Preferably, the perforations are polygons, radial, circular, or square.

[0073] In one embodiment, the solid elastic material plate 12 is plate-shaped. Since each plate is independently stressed, even if some solid elastic material cracks during loading and unloading, only the solid elastic material plate 12 where the crack occurs fails, and the crack does not spread to other solid elastic material plates, i.e., the solid elastic material does not fail as a whole, thereby improving the service life of the solid elastic material. In addition, the plate-shaped solid elastic material plate 12 greatly reduces the damage of the loading force to the material during the loading process after stacking, thereby avoiding buckling deformation of the material.

[0074] In practical applications, in order to avoid the misalignment or perforation of the solid elastic clamping material plate 12 after stacking, the solid elastic clamping material plate 12 and the fixed sleeve 11 can be provided with a limiting structure for limiting the rotation between the solid elastic clamping material plate 12 and the fixed sleeve 11.

[0075] The limiting structure can be a limiting structure formed by the shapes of the solid elastic clamping material plate 12 and the fixed sleeve 11, or an interference fit relationship between the solid elastic clamping material plate 12 and the fixed sleeve 11, or a limiting member separately provided in the fixed sleeve 11.

[0076] In an embodiment, the inner wall of the fixed sleeve 11 is clamped with the solid elastic clamping material plate, that is, the shape of the inner wall of the fixed sleeve 11 is the same as that of the solid elastic clamping material plate and there is a gap or the solid elastic clamping material plate internally fits the inner wall of the fixed sleeve 11. For example, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic clamping material plate can be irregular polygons, polygons, squares, etc. containing angles, which can be clamped with each other and are not easy to rotate. In the embodiment of the present application, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic clamping material plate are preferably hexagonal. In some embodiments, the solid elastic clamping material plate can also internally fit the inner wall of the fixed sleeve 11. Preferably, the inner wall of the fixed sleeve 11 is circular or has a circular arc shape, and the solid elastic clamping material plate is square or polygonal to facilitate internal fitting. For example, the inner wall of the fixed sleeve 11 is circular, and the solid elastic clamping material plate is square, and the circle is internally fitted in the square; the inner wall of the fixed sleeve 11 is a rectangle with a right angle in a circular arc shape, and the solid elastic clamping material plate is a rectangle or a hexagon.

[0077] In order to fix the position of the stacked solid elastic clamping material plate, the fixed sleeve 11 can also be provided with a limiting member to limit the movement of the solid elastic clamping material plate. For example, a protrusion is provided along the radial direction of the inner wall of the fixed sleeve 11, and a recess is provided on the edge of the solid elastic clamping material plate, so that the protrusion of the fixed sleeve 11 extends into the recess of the stacked solid elastic clamping material plate to limit the position. In another embodiment, the stacked solid elastic clamping material plate is fixed by the limiting member and then fixed with the fixed sleeve 11. For example, a rod-shaped limiting member is inserted into the flow cavity of the stacked solid elastic clamping material plate, and the rod-shaped member is fixed with the fixed sleeve 11 by a fixing device.

[0078] As shown in Figure 5 In a specific embodiment, each solid elastic clamping material plate 12 comprises a groove 122, and a plurality of grooves 122 stacked to form a space for accommodating the protrusion 113 of the inner wall of the fixed sleeve 11. After the protrusion 113 extends into the space formed by the stacked grooves 122, the gap between the inner wall of the fixed sleeve 11 and the outer surface of the stacked solid elastic clamping material plate 12 forms an additional flow cavity for the flow of the heat-conducting fluid.

[0079] In practical applications, the greater the mass or volume of the solid elastic card material, the more heat or cold it generates. Therefore, in order to maximize the heat or cold generated by the solid elastic card material to be absorbed by the medium, the amount of the solid elastic card material needs to be matched with the heat transfer capacity in this embodiment. Generally, a larger flow cavity size can ensure that the same mass of solid elastic card material has a larger specific surface area or volume.

[0080] The grooves 122 of each solid elastic card material plate and the protrusions 113 of the inner wall of the fixed sleeve 11 are multiple and one-to-one. The number of the protrusions 113 of the inner wall of the fixed sleeve 11 is the same as the number of the grooves 122 formed after the stacking of the solid elastic card material plates 12, and the protrusions 113 are respectively embedded in the grooves 122 of the solid elastic card material plates 12. In this embodiment, the protrusions 12 extend longitudinally along the fixed sleeve 11, and the length thereof is greater than or equal to the length of the stacked solid elastic card material plates 12. In this way, the position of the solid elastic card material plates 12 can be fixed to a certain extent, and the dislocation thereof can be limited.

[0081] As shown in Figure 3 , in some embodiments, the solid elastic card regenerator 10 further comprises an outer sleeve 15, which is sleeved outside the fixed sleeve 11 and is in interference fit with the fixed sleeve 11.

[0082] In practical applications, the assembled fixed sleeve 11 and the pressure head 13 are placed in the outer sleeve 15, which not only fixes each mechanism, but also facilitates the replacement of the components.

[0083] As shown in Figure 3 and Figure 4 , the fixed sleeve 11 comprises a first half sleeve 111, a second half sleeve 112, and a longitudinal sealing member of the fixed sleeve 11. The first half sleeve 111 is internally provided with a first half groove; the second half sleeve 112 is internally provided with a second half groove and is buckled with the first half sleeve 111 through a positioning structure, so that the first half groove and the second half groove form a sleeve cavity for accommodating a plurality of solid elastic card material plates 12; and the longitudinal sealing member of the fixed sleeve 11 is arranged between the first half sleeve 111 and the second half sleeve 112 to seal the joint between the first half sleeve 111 and the second half sleeve 112.

[0084] In this way, the installation and replacement of the solid elastic card material plates 12 can be facilitated, and the overall strength of the structure can be ensured. In addition, the specific heat capacity of the fixed sleeve 11 can be selected according to the material thereof to ensure heat preservation.

[0085] It should be noted that the fixed sleeve 11 is preferably made of a high polymer material, which can be nylon, polyester, hard silica gel, resin, etc., and is preferably made of polytetrafluoroethylene. During the stress loading process of the driving mechanism 3, the solid-state refrigeration and heating plate 12 will expand laterally. Using a high polymer material can accommodate the expanded size and buffer the lateral pressure. On the other hand, the high polymer material has poor thermal conductivity, which can also prevent the heat loss of the heat conducting fluid.

[0086] In a specific embodiment, the positioning structure between the first half cylinder 111 and the second half cylinder 112 can be a structure of protrusions and grooves, or a hole or slot structure positioned by fasteners or positioning pins, etc., to facilitate the positioning and alignment of the first half cylinder 111 and the second half cylinder 112.

[0087] The cylinder cavity can be a cylindrical, square, rectangular, etc. shaped cavity, and its inner wall is in close contact with the solid-state refrigeration and heating plate 12. Thus, during assembly, the solid-state refrigeration and heating plate 12 can be placed in the fixed sleeve 11. The specific fixing method of the fixed sleeve 11 to the solid-state refrigeration and heating plate 12 can be selected as needed.

[0088] Specifically, as shown in Figure 3 In a specific embodiment, the pressure head 13 includes a moving pressure head 131, a moving pressure head seal, a distribution pressure head 132, and a driving pressure head 133. The moving pressure head 131 is slidingly arranged in the cylinder cavity and abuts against the solid-state elastic material plate 12. The moving pressure head 131 is provided with a first flow hole communicating with the flow cavity. The moving pressure head seal is arranged between the moving pressure head 131 and the inner wall of the cylinder cavity to seal and prevent leakage of the medium. The distribution pressure head 132 is connected to the end of the moving pressure head 131 away from the solid-state elastic material plate 12 and is provided with a second flow hole and a plurality of distribution holes. The second flow hole communicates with the first flow hole, and the plurality of distribution holes communicate with the second flow hole at one end and are connected to and communicate with the medium conveying pipeline assembly for input and output of the heat conducting medium. The driving pressure head 133 is slidingly arranged in the outer sleeve 15 and is connected to the distribution pressure head 132 and the driving rod 25 to transmit power.

[0089] Preferably, the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 has the same cross-sectional shape, and the first flow hole is located at the center of the moving pressure head 131 and coaxial with the cavity. In this embodiment, the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 has the same cross-sectional shape and completely covers the cross-section of the solid-state refrigeration and heating plate, which can ensure that the solid-state refrigeration and heating plate completely changes phase during stress loading, thereby improving the efficiency of refrigeration and heating. In addition, by arranging the first flow hole at the center of the moving pressure head 131, the heat conducting fluid in the cavity at each angle can flow out from the first flow hole at the same flow rate.

[0090] In order to increase the loading strength, the dynamic pressure head 131 can be made of high-strength tungsten steel.

[0091] Further, in order to reduce friction and improve the movement accuracy of the dynamic pressure head 131, a sliding rail is arranged in the outer sleeve 15, and the driving pressure head 133 is in sliding fit with the outer sleeve 15 through the sliding rail, so that the driving pressure head 133 slides along the sliding rail during loading or unloading.

[0092] In some embodiments, the sliding rail in the inner wall of the outer sleeve 15 in contact with the fixed sleeve 11 can be provided with a clamping piece for fixing the fixed sleeve 11, or the part of the inner wall of the outer sleeve 15 overlapping the fixed sleeve 11 can not be provided with a sliding rail, and only a guide rail is arranged at the port of the outer sleeve 15.

[0093] In another embodiment, in order to realize heat exchange, that is, to transport the heat-absorbing or cold-absorbing heat-conducting fluid into the heat exchange device as soon as possible, the plug structure 14 arranged at the other end of the fixed sleeve 11 is a water distribution plug, the water distribution plug is provided with a liquid passage, the liquid passage is in communication with the flow cavity, and is connected and communicated with the medium conveying pipeline assembly, so as to input and output the heat-conducting medium.

[0094] In some specific embodiments, as shown in Figure 1 The refrigeration and heating equipment further comprises a shell 40, the shell 40 covers the solid-state elastic card regenerator 10 and the multi-link transmission mechanism 20 outside, the power mechanism 30 is arranged on the shell 40, and one end of the rotating main shaft 21 penetrates through the shell 40, and the multi-link transmission mechanism 20 further comprises a compensation transmission assembly 27, the compensation transmission assembly 27 is arranged between the power mechanism 30 and the rotating main shaft 21, so as to perform compensation transmission. The main shaft support 26 can be fixedly arranged on the shell 40.

[0095] The compensation transmission assembly 27 can be a gear transmission assembly or a chain transmission assembly, which can perform distance compensation.

[0096] Specifically, the power mechanism 30 can be a speed-reducing motor or an internal combustion engine, which can output rotating power.

[0097] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
