The purpose is to ensure that child safety seats can be installed correctly, quickly and securely in the car, and to improve the safety of children traveling in the car. By tightly connecting the ISOFIX interface of the child safety seat with the fixing points on the car seat, a rigid connection structure is formed. This connection method can effectively fix the child safety seat on the vehicle when the vehicle collides or brakes suddenly, reducing the displacement and shaking of the seat, thereby maximizing the safety of children. At the same time, the top restraint belt can further limit the rotation and inclination of the seat when activated, providing more comprehensive protection. The bottom of the ISOFIX assembly is provided with a shell structure for fixing ISOFIX. For the shell structure, welding equipment needs to be welded.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention utilizes a collaborative design of a deformable hot plate structure and a deformable structure, allowing the deformable hot plate structure to switch between straight and curved plate configurations according to welding requirements. When processing the curved edge of a shell, a linear drive structure secures one end of the thermal foil, cooperating with the deformation layer to contract and generate stress. A bending limiter structure constrains the movement of the other end of the thermal foil, bending the foil into a preset arc to conform to the shell's curved surface for hot plate welding. When processing straight edges, the deformation layer returns to its initial state, and the linear drive structure rotates one end of the thermal foil to a horizontal position, achieving flat welding. This dual-mode deformation system allows continuous welding of both straight and curved shell edges without requiring tooling changes, effectively welding the shell and avoiding cold or leaky welds.

[0025] 2. This invention utilizes an auxiliary deformation system composed of pneumatic cylinders. After the deformable heat plate structure is deformed, the cylinders, through their output ends, push the thermal foil in front of the deformation layer. This causes the foil to undergo a micro-displacement within the deformed state, causing the foil to bulge or contract. This dynamically compensates for thermal deformation during welding and improves weld penetration consistency. By using pneumatic cylinders to achieve localized deformation of the foil, this invention achieves refined local adjustments during welding, improving weld pass rates.

[0026] 3. The present invention provides bending grooves on the side of the thermal conductive foil close to the deformation layer. The bending grooves are evenly spaced along the long axis of the thermal conductive foil and have a trapezoidal cross-section. This allows the thermal conductive foil to generate stress concentration points when deformed, guiding the thermal conductive foil to bend along a preset trajectory.

[0027] When the shape memory alloy activation section contracts upon power application, the bending grooves reduce the local stiffness of the thermal foil, enabling it to complete the desired arc deformation in a shorter time. Combined with the localized pushing action of the micro-cylinder, the bending grooves generate additional elastic deformation, precisely compensating for weld surface tolerances. This invention uses the bending grooves to guide the foil along a predetermined trajectory during deformation, while also increasing the speed at which the foil completes its arc deformation.

[0028] 4. The present invention forms a two-dimensional adjustment system through transverse and longitudinal limit bolts. When it is necessary to weld shells of different curvatures, the longitudinal limit bolts are first loosened to move the longitudinal guide rod to the target height. The transverse limit bolts are then loosened to adjust the transverse position of the fixing seat on the slide rail. The longitudinal and transverse limit bolts are then tightened to form a rigid limit. The present invention adjusts the longitudinal position of the longitudinal guide rod and the transverse position of the fixing seat through the longitudinal and transverse limit bolts, thereby adjusting the limit range of the bending limit structure and controlling the deformation curvature of the deformable hot plate structure.

[0051] The deformable hot plate structure 2 comprises a heat-conducting foil 201, a heating wire 202 and a deformation layer 203, the heat-conducting foil 201 and the deformation layer 203 are integrated, and the heating wire 202 is arranged in the heat-conducting foil 201 along the long axis direction of the heat-conducting foil 201, the deformation layer 203 has a straight plate state and an arc plate state, and is used for driving the heat-conducting foil 201 to deform between the straight plate structure and the arc plate structure, and the orientations of the deformable hot plate structures 2 on the two welding parts are respectively adapted to the upper shell and the lower shell.

[0052] The deformation structure 3 has a curved state and a straight state, and comprises a curved limiting structure 301 and a linear drive structure 302; in the curved state, the linear drive structure 302 fixes one end of the heat-conducting foil 201, the curved limiting structure 301 limits the movement range of the other end of the heat-conducting foil 201, the deformation layer 203 deforms the heat-conducting foil 201 into an arc plate structure with a specific arc, and is used for hot plate welding of the arc edge of the upper shell or the lower shell; in the straight state, the linear drive structure 302 drives the movement of one end of the heat-conducting foil 201, the curved limiting structure 301 assists the movement of the other end of the heat-conducting foil 201, and the deformation layer 203 deforms the heat-conducting foil 201 into a straight plate structure parallel to the welding table 1, and is used for hot plate welding of the straight edge of the upper shell or the lower shell.

[0053] The welding table 1 is also provided with a carrying structure 4, and the carrying structure 4 is used for carrying the FIX assembly shell.

[0054] ​The deformable hot plate structure 2 can be switched between a straight plate and an arc plate form according to the welding requirements through the cooperative design of the deformable hot plate structure 2 and the deformation structure 3, when the arc edge of the processing shell is processed, the linear driving structure 302 fixes one end of the heat conduction foil 201, cooperates with the deformation layer 203 to generate stress through contraction, the bending limiting structure 301 restricts the movement track of the other end of the heat conduction foil 201, so that the heat conduction foil 201 is bent into a preset arc, and the heat plate welding is performed on the curved surface of the shell; when the straight edge is processed, the deformation layer 203 returns to the initial state, and the linear driving structure drives one end of the heat conduction foil 201 to rotate to the horizontal position, so that the plane welding is realized. Through the deformation system of the double mode, the continuous welding of the straight edge and the arc edge of the shell can be completed without replacing the tooling, so that the shell is effectively welded, and the virtual welding and the missing welding are avoided.

[0055] Specifically, as shown in Figure 4 The deformation layer 203 is connected with the power supply device 204, the deformation layer 203 is divided into an activation part and a reset part, the activation part and the reset part are both independently arranged shape memory alloys, and the surfaces of the shape memory alloys are covered with flexible thermal insulation materials, and the activation part and the reset part respectively become an arc plate original state and a straight plate original state after being powered.

[0056] The deformation layer 203 is designed by the innovative double driving deformation layer 203, the accurate regulation and control of the hot plate form are realized, the deformation layer 203 is composed of an activation part and a reset part which are independently controlled, and both of which adopt nickel-titanium shape memory alloy NiTi SMA; when it is needed to become an arc plate state, the activation part generates resistance heat after being powered, when the temperature reaches the austenite transition point of 65 DEG C, the molecular structure of the memory alloy is reorganized, the heat conduction foil 201 is driven to bend into a preset arc plate state, and the reset part is not powered and becomes a low-temperature martensite which deforms along the activation part;

[0057] When it is needed to become a straight plate state, the reset part generates resistance heat after being powered, when the temperature reaches the austenite transition point of 65 DEG C, the molecular structure of the memory alloy is reorganized, the heat conduction foil 201 is driven to become a preset straight plate state, and the activation part is not powered and becomes a low-temperature martensite which deforms along the reset part;

[0058] The two groups of memory alloys independently work and do not interfere with each other, after fatigue test, the deformation layer 203 still maintains a relatively high shape recovery rate, and the service life is improved compared with the traditional spring driving. The design of the present application shortens the hot plate form switching time and reduces the welding energy consumption, and is especially suitable for the precision manufacturing scene which needs to frequently switch the welding form.

[0060] The linear driving structure 302 comprises a rack 3021, a gear 3022, a servo motor 3023, and a limiting shell 3024; the rack 3021 is connected with the mounting seat 208 at the top end of the heat-conducting foil 201, the gear 3022 is meshingly connected on one side of the rack 3021, the gear 3022 is installed on the output end of the servo motor 3023, the servo motor 3023 is installed on the limiting shell 3024, the gear 3022 is arranged in the limiting shell 3024, and the rack 3021 is slidably connected on the limiting shell 3024.

[0061] The linear driving structure 302 further comprises a third limiting sliding block 3025 and a second transverse guide rod 3026; the third limiting sliding block 3025 is installed on the limiting shell 3024, the third limiting sliding block 3025 is slidably connected on the second transverse guide rod 3026, and the second transverse guide rod 3026 is connected with a sliding rail 304.

[0062] The present application realizes the accurate control of the deformation of the heat plate through the double-mode limiting structure; in the bending limiting structure 301, the first limiting sliding block 3011 is hinged with the mounting seat 208 at the bottom end of the heat-conducting foil 201 and is transversely slid along the first transverse guide rod 3012, the second limiting sliding block 3013 moves longitudinally on the longitudinal guide rod 3014, forming an X-Y axis bidirectional limiting system; when the heat-conducting foil 201 is bent, the second limiting sliding block 3013 limits the transverse displacement of the first limiting sliding block 3011, the second limiting sliding block 3013 restricts the bending center position through the longitudinal guide rod 3014, and the heat-conducting foil 201 is accurately deformed according to the preset radius;

[0064] Further, as shown in the drawings, Figures 3 to 4 The side of the deformation layer 203 is attached with a mounting soft plate 205, ten air cylinders 206 are equidistantly mounted on the mounting soft plate 205, the output ends of the ten air cylinders 206 are connected to the heat conduction foil 201, and the output ends of the air cylinders 206 are located at the gap between the starting part and the reset part.

[0065] The auxiliary deformation system composed of the air cylinders 206 drives the heat conduction foil 201 in front of the deformation layer 203 to move after the deformable heat plate structure 2 is deformed, so that the heat conduction foil 201 is further locally displaced by the air cylinders 206 on the basis of the deformed state, and the partial structure of the heat conduction foil 201 is protruded or shrunk, thereby dynamically compensating the thermal deformation of the heat conduction foil 201 in the welding process, and improving the consistency of the weld penetration.

[0066] Further, as shown in the drawings, Figure 4 The side of the heat conduction foil 201 close to the deformation layer 203 is equidistantly provided with fifty curved grooves 2011 along the long axis direction, and the curved grooves 2011 are trapezoidal structures, and the cross-sectional openings of the curved grooves 2011 gradually increase in the direction towards the outside of the heat conduction foil 201.

[0067] The curved grooves 2011 are equidistantly distributed along the long axis direction of the heat conduction foil 201, and the cross section is trapezoidal, so that the heat conduction foil 201 can generate stress concentration points when deformed, and guide the heat conduction foil 201 to bend along the preset track, when the shape memory alloy starting part is energized to shrink, the curved grooves 2011 weaken the local rigidity of the heat conduction foil 201, so that the heat conduction foil 201 completes the preset arc deformation in a shorter time, and cooperates with the local pushing of the micro air cylinder 206, the curved grooves 2011 can produce additional elastic deformation, and accurately compensate the tolerance of the curved surface of the welding part.

[0069] The present invention forms a two-dimensional adjustment system through the transverse limiting bolts 305 and the longitudinal limiting bolts 306. When it is necessary to weld shells of different curvatures, the longitudinal limiting bolts 306 are first loosened to move the longitudinal guide rod 3014 to the target height. The transverse limiting bolts 305 are then loosened to adjust the transverse position of the fixing seat 303 on the slide rail 304. The longitudinal limiting bolts 306 and the transverse limiting bolts 305 are then tightened to form a rigid limit. The present invention adjusts the longitudinal position of the longitudinal guide rod 3014 and the transverse position of the fixing seat 303 through the longitudinal limiting bolts 306 and the transverse limiting bolts 305, thereby adjusting the limit range of the bending limiting structure 301 and controlling the deformation curvature of the deformable hot plate structure 2.
