Unless otherwise specified, the dimensions, materials, manufacturing processes, etc. of the various components in the new energy vehicle battery radiator suitable for adjustable heat dissipation angle in the embodiments of the present invention can be selected according to specific circumstances, and no special limitations and explanations are made here.

[0026] Furthermore, in order to enable the public to have a better understanding of the present invention, in the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details.

[0027] Please refer to Figures 1 - 5, this embodiment provides a new energy vehicle battery radiator with adjustable heat dissipation angle, including a fixed seat 1, a cooling box 2, a contact plate 3, a grille assembly 4, a cooling mechanism 5, a heat dissipation mechanism 6 and a transmission mechanism 7; Cooling boxes 2 are provided on both sides of the fixed seat 1. The contact plate 3 is arranged at the bottom of the fixed seat 1 and the cooling boxes 2. The cooling mechanism 5 is arranged on the cooling boxes 2 and can absorb the heat of the battery. It should be understood that the contact plate 3 can contact and conduct heat with the new energy battery. There is a coolant in the cooling box 2, and heat absorption and cooling are achieved through the flow of the coolant.

[0028] The grille assembly 4 is rotatably arranged on the fixed seat 1. The heat dissipation mechanism 6 is arranged in the fixed seat 1 and can discharge heat to the grille assembly 4. Specifically, the heat dissipation mechanism 6 can absorb the heat of the contact plate 3 and the cooling mechanism 5 and discharge it to the grille assembly 4. The transmission mechanism 7 is slidably arranged in the fixed seat 1 and is connected to the heat dissipation mechanism 6. The heat dissipation mechanism 6 can drive the transmission mechanism 7 to reciprocate slidingly, and the sliding of the transmission mechanism 7 can drive the grille assembly 4 to swing.

[0029] Specifically, there are multiple heat dissipation mechanisms 6. The transmission mechanism 7 is connected to one of the heat dissipation mechanisms 6. The movement of the heat dissipation mechanism 6 can drive the transmission mechanism 7 to perform linear reciprocating motion. The reciprocating motion of the transmission mechanism 7 drives the grille assembly 4 to swing back and forth on both sides, thereby changing the angle of heat discharge. Specifically, when the transmission mechanism 7 slides to one side of the stroke, it drives the grille assembly 4 to rotate to one side. When the transmission mechanism 7 slides to the other side of the stroke, it drives the grille assembly 4 to slide to the other side. The grille assembly 4 rotates to both sides at its maximum air outlet angle, that is, during the movement stroke of the transmission mechanism 7, the grille assembly 4 can be at the maximum air outlet angle, that is, the position where the grille assembly 4 is perpendicular to the fixed seat 1. This position is preferably the middle position of the stroke of the first slider 71.

[0030] Preferably, a clamping and installation mechanism is further provided at the bottom of the fixed seat 1. The clamping and installation mechanism has been described in detail in the prior art, such as shown in CN114464917A, so it will not be elaborated in this application.

[0031] In this application, the heat dissipation mechanism 6 drives the grille assembly 4 to swing reciprocally through the transmission mechanism 7, so as to continuously change the heat dissipation angle during the heat dissipation process, thereby avoiding the fixed angle during the heat dissipation process, causing local overheating in the new energy vehicle and affecting the operation of corresponding electrical components or other parts. At the same time, in this application, the heat dissipation mechanism 6 spontaneously drives the grille assembly 4 to rotate through the transmission mechanism 7 during operation, without the need for an additional power source to change the angle of the grille assembly 4 from the outside, which reduces the wiring difficulty after the radiator is installed.

[0032] In other solutions, the heat dissipation mechanism 6 includes a motor 61, a driving rotating shaft 62, and heat dissipation fins 63; the motor 61 is arranged in the fixed seat 1, the driving rotating shaft 62 is coaxially fixed on the output shaft of the motor 61, a plurality of heat dissipation fins 63 are circumferentially arranged on the driving rotating shaft 62, the transmission mechanism 7 is connected to the driving rotating shaft 62, and the rotation of the driving rotating shaft 62 can drive the transmission mechanism 7 to perform linear reciprocating motion. Preferably, the motor 61 can be driven by its own battery or connected to the power supply of a new energy vehicle through a wire.

[0033] In other solutions, the transmission mechanism 7 includes a transmission component 71 and a connection component 72; the transmission component 71 is slidably arranged in the fixed seat 1 and is connected to the grille component 4 through a connection mechanism; the transmission component 71 is connected to the heat dissipation mechanism 6, the rotation of the heat dissipation mechanism 6 can drive the transmission component 71 to perform linear reciprocating motion, and the sliding of the connection component 72 can drive the grille component 4 to rotate. It should be understood that the driving rotating shaft 62 of the heat dissipation mechanism 6 is connected to the transmission component 71, the movement of the transmission component 71 drives the connection component 72 to move, and the reciprocating movement of the connection component 72 drives the grille component 4 to swing back and forth.

[0034] In other solutions, the transmission mechanism 7 includes a transmission plate 711, a first hinge shaft 712, a driven plate 713, a second hinge shaft 714, and a first slider 71; one end of the transmission plate 711 is arranged on the heat dissipation mechanism 6, and the other end is connected to the driven plate 713 through the first hinge shaft 712, the driven plate 713 is connected to the first slider 71 through the second hinge shaft 714, the first slider 71 is slidably connected to the fixed seat 1 and is connected to the connection component 72. Specifically, the first slider 71 performs linear reciprocating motion on the fixed seat 1, the driving rotating shaft 62 of the heat dissipation mechanism 6 is connected to the transmission plate 711, the end of the transmission plate 711 away from the driving rotating shaft 62 is hinged to the driven plate 713 through the first hinge shaft 712, and the bottom surface of the transmission plate 711 is higher than the heat dissipation fins 63. At the same time, the first hinge shaft 712 and the end of the transmission plate 711 close to the driving rotating shaft 62 are away from the heat dissipation fins 63, that is, the first hinge shaft 712 and the driven plate 713 do not interfere with the heat dissipation fins 63 during movement, and the driven plate 713 is hinged to the first slider 71 through the second hinge shaft 714.

[0035] In other solutions, the connecting component 72 includes a connecting rod 721, a second slider 722, and an elastic telescopic tube 723; the second slider 722 is slidably connected to the fixed seat 1 and is connected to the first slider 71 through the connecting rod 721. One end of the elastic telescopic tube 723 is arranged on the second slider 722, and the other end is connected to the grille assembly 4. The sliding of the elastic telescopic tube 723 can drive the grille assembly 4 to rotate. Specifically, the elastic telescopic tube 723 includes a fixed tube 7231, a sliding tube 7232, and a return spring 7233; the fixed tube 7231 is fixed on the second slider 722, the sliding tube 7232 is slidably connected to the fixed tube 7231 coaxially and is connected to the grille assembly 4, one end of the return spring 7233 is connected inside the fixed tube 7231, and the other end is connected inside the sliding tube 7232.

[0036] In other solutions, the grille assembly 4 includes guide vanes 41, a guide rotating shaft 42, and a grille connecting plate 43; the guide vanes 41 are rotatably connected to the fixed seat 1 through the guide rotating shaft 42. A plurality of guide vanes 41 are provided and are connected to the grille connecting plate 43, and the grille connecting plate 43 is connected to the transmission mechanism 7. Specifically, the guide rotating shafts 42 and the guide vanes 41 are in one-to-one correspondence, and the axes of the guide rotating shafts 42 are on the same horizontal plane. The bottom surfaces of the guide vanes 41 are all connected to the grille connecting plate 43, and the grille connecting plate 43 is connected to the elastic telescopic tube 723. During the reciprocating movement of the elastic telescopic tube 723, it expands and contracts due to the different angular positions of the guide vanes 41, thereby driving the grille connecting plate 43 to rise and fall during the movement.

[0037] In other solutions, the cooling mechanism 5 includes a feed pipe 51, a first transfer pipe 52, a water pump 53, and a second transfer pipe 54; a feed pipe 51 is provided on a cooling box 2, and the feed pipe 51 is closed by a sealing cover; preferably, the feed pipe 51 is a threaded pipe and is communicated with the inside of the cooling box 2. The sealing cover is connected to the inside of the feed pipe 51 by threading, and coolant can be added to the cooling box 2 through the feed pipe 51. The two ends of the first transfer pipe 52 are respectively communicated with two cooling boxes 2 on the same side. The water pump 53 is arranged on the cooling box 2 and is connected to the first transfer pipe 52. The second transfer pipe 54 communicates with the other sides of the two cooling boxes 2; there is an opening or a plurality of ventilation holes on the fixed seat 1 near the second transfer pipe 54. It should be understood that by starting the water pump 53, the coolant in the cooling box 2 can be made to flow. Through the opening or ventilation holes on the fixed seat 1, when the heat dissipation mechanism 6 is started, the hot air on the second transfer pipe 54 can be sucked into the fixed seat 1 and discharged through the grille assembly 4. Preferably, a plurality of second transfer pipes 54 are provided.

[0038] In other solutions, a lifting mechanism 8 and a pushing mechanism 9 are further provided; the transmission plate 711 includes a fixing plate 7111, a sliding plate 7112, a connecting plate 7113, a support spring 7114, and a wedge 7115. The fixing plate 7111 is fixedly arranged on the driving rotating shaft 62. A chute is provided on the fixing plate 7111. The sliding plate 7112 is slidably connected to the chute and is hinged with a first hinge shaft 712. The connecting plate 7113 is respectively arranged on the fixing plate 7111 and the sliding plate 7112 and is connected by the support spring 7114. The wedge 7115 is fixedly arranged on the sliding plate 7112. The lifting mechanism 8 is arranged on the fixed seat 1 and can be lifted when the temperature of the battery rises. The pushing mechanism 9 is arranged in the fixed seat 1 in a liftable manner and is connected to the lifting mechanism 8. The lifting of the pushing mechanism 9 can squeeze the wedge 7115, causing the sliding plate 7112 to move towards the fixing plate 7111. That is, when the heat generated by the battery is excessive, the transmission plate 711 is shortened through the lifting mechanism 8 and the pushing mechanism 9. The shortening of the transmission plate 711 reduces the sliding stroke on both sides of the first slider 71, that is, shortens the rotation angle of the grille assembly 4 to both sides, causing the grille assembly 4 to swing near the maximum air outlet volume. Thus, when the automotive battery overheats, the change in the heat dissipation angle can be maintained to avoid the concentration of the heat dissipation angle, and at the same time, the heat dissipation air volume can be made as large as possible. It should be understood that the support spring 7114 is in a compressed state, and the elastic force of the support spring 7114 can overcome the reaction forces brought by the grille assembly 4 and the connecting assembly 72, causing the sliding plate 7112 to be in a position away from the fixing plate 7111.

[0039] In other solutions, the lifting mechanism 8 includes a storage box 81, a movable plate 82, and a lifting rod 83. The storage box 81 is fixedly arranged on the fixed seat 1. The movable plate 82 is arranged in the storage box 81 in a liftable manner, and the space between the storage box 81 and the movable plate 82 forms an airtight space filled with an inert gas that can expand when heated. A lifting rod 83 is fixedly arranged on the side of the movable plate 82 away from the storage box 81, and the lifting rod 83 is connected to the pushing mechanism 9. Specifically, the inert gas in the storage box 81 expands when heated, driving the movable plate 82 to lift upwards, and then driving the pushing mechanism 9 to lift through the lifting rod 83, causing the pushing mechanism 9 to squeeze the wedge 7115 and the transmission plate 711 to contract.

[0040] In other solutions, the pushing mechanism 9 includes a pushing telescopic tube 91 and a pushing connecting rod 92. The pushing telescopic tube 91 is fixedly arranged on the fixed seat 1 and is coaxial with the driving rotating shaft 62. The telescopic end of the pushing telescopic tube 91 is connected to the lifting rod 83 through the pushing connecting rod 92. After the pushing telescopic tube 91 is lifted, it can squeeze the wedge 7115. Preferably, after the pushing telescopic tube 91 squeezes the inclined surface of the wedge 7115, it abuts against the flat surface of the wedge 7115, which can better maintain this length. It should be understood that a long hole is provided on the fixed seat 1 to allow the pushing connecting rod 92 to pass through when it is lifted.

[0041] The above-mentioned new energy vehicle battery radiator with adjustable heat dissipation angle can continuously change the heat dissipation angle during operation to avoid local overheating.
