[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the plug-in quick fixing mechanism of the motor vehicle heater adopts a new structural design, and the protective plate is provided to play a role of dust prevention and protection, so that the plug-in will not be accidentally touched when in use. At the same time, a fixing plate is provided, and the fixing plate supports the plug-in under the action of the second spring, plays a fixing role, so that the plug-in will not fall off during operation. In addition, a dust cleaning component of the air permeable net is provided, so that dust will not remain on the air permeable net, and the overall heat dissipation effect of the device is optimized. The specific contents are as follows: (1) The plug-in quick fixing mechanism of the train heater has the following characteristics: initially, the end of the card block is located inside the card slot, and the protective plate is in a state of covering the socket, so that dust does not enter the socket, thereby ensuring the stability of the plug-in connection and the subsequent operation of the plug-in. When the plug-in needs to be connected, the handle is pulled to move the end of the card block out of the card slot. At this time, the protective plate and the connecting shaft rotate and unfold under the action of the torsion spring, exposing the socket. When the protective plate is unfolded, it also plays a role in preventing accidental touch, thereby optimizing the protection effect. Furthermore, when the handle drives the card block to move downward, the card block drives the limit block to slide inside the fixed block. At this time, the limit block will squeeze the first spring. After the handle and the card block are released, the limit block returns to its original position under the action of the first spring, which is convenient for the next use. The limit block limits the moving distance of the card block to ensure stability. Furthermore, when the protective plate needs to be retracted, the protective plate is rotated back, and the protective plate drives the connecting shaft to rotate inside the overlap block, so that the torsion spring is stretched again, and when the end of the protective plate contacts the card block, the limit block moves in the direction of squeezing the first spring, and when the card block and the card slot are in the same vertical direction, the card block enters the card slot under the action of the limit block and the first spring, and the protective plate is in a state of covering the socket again, so that dust will not enter the socket; (2) The plug-in fast fixing mechanism of the motor vehicle heater is that when the protective plate covers the socket, the baffle and the upper connecting rod are in contact, and the baffle presses against the upper connecting rod. At this time, the fixed plate is in a state of squeezing the second spring. When the protective plate and the connecting shaft rotate, the baffle rotates synchronously, and the upper connecting rod and the fixed plate are not squeezed. At this time, the fixed plate moves toward the socket under the action of the limit rod and the second spring. Finally, the fixed plates on the left and right sides will press against the plug-in under the action of the second spring, thereby fixing the plug-in. The operation process is smooth and fast. (3) The plug-in quick fixing mechanism of the EMU heater will drive the external rod to move synchronously when the inner fixing plate moves. When the external rod moves, the second magnet will approach the first magnet in sequence. At this time, the movable plate will make reciprocating linear motion in the vertical direction under the action of the mutual magnetic force, the guide rod, the connecting plate and the third spring. Then the movable plate will drive the striking rod to strike the outer wall of the breathable net again and again to make the dust fall off, so that the breathable net can work normally, ensuring the normal heat dissipation effect of the heater body. The through holes on the surface of the movable plate will not affect the exchange of air inside and outside. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: By setting the protection component, dust can be prevented from entering the interior of the socket 2, so that the socket 2 can maintain a normal state when in use, and the protection plate 5 can also be quickly unfolded. When the protection plate 5 is unfolded, the connector can be protected. Figure 1-Figure 5 As shown: The heater body 1 includes a heater body 1 and a lap block 3. A mounting plate is fixedly connected to the side of the heater body 1. The mounting plate is docked at a required position when working. A socket 2 is provided on the surface of the heater body 1. When the socket 2 is working, it is docked with an external plug. The lap block 3 is fixedly connected to the outer wall of the heater body 1. A quick fixing mechanism for a plug-in connector of a motor vehicle heater, further comprising: A protection assembly, which is movably arranged on the outer wall of the heater body 1, and includes a protection plate 5 rotatably arranged on the surface of the heater body 1, and a fixing block 7 is fixedly connected to the outer wall of the heater body 1; A pressurized fixing assembly, which is slidably arranged on the surface of the heater body 1, and comprises a limit rod 13 fixedly connected to the surface of the heater body 1, and a fixing plate 14 is sleeved and connected to the surface of the limit rod 13; The ash cleaning component is arranged on the heater body 1 , and the ash cleaning component includes a striking rod 22 movably arranged on the surface of the heater body 1 , and the surface of the heater body 1 is fixedly connected with a guide rod 18 .

[0020] The protection component also includes a lap block 3 fixedly connected to the outer wall of the heater body 1, and a connecting shaft 4 is rotatably arranged inside the lap block 3, and the lap block 3 is symmetrically distributed about the center of the socket 2, a protection plate 5 is fixedly connected to the surface of the connecting shaft 4, and a card slot 6 is opened on the lower surface of the protection plate 5, and a card block 8 corresponding to the card slot 6 is slidably arranged inside the fixed block 7, and the end of the card block 8 is inclined.

[0021] A handle 26 is fixedly connected to the lower surface of the block 8, and the left and right sides of the block 8 are fixedly connected to the limit blocks 9, and the lower surface of the limit blocks 9 is fixedly connected to the first spring 10 which plays an elastic reset role, and the other side of the first spring 10 is fixedly connected to the inner wall of the fixed block 7.

[0022] A torsion spring 11 having an elastic reset function is fixedly connected to the surface of the connecting shaft 4 , and the other side of the torsion spring 11 is fixedly connected to the inner wall of the lap block 3 , and the torsion spring 11 is initially in a compressed state.

[0023] Initially, the end of the card block 8 is located inside the card slot 6. At this time, the protective plate 5 is in a state of covering the socket 2, so that dust will not enter the socket 2, ensuring the stability of the connector docking and the subsequent operation of the connector. When the connector needs to be docked, the handle 26 is pulled to move the end of the card block 8 out of the card slot 6. At this time, the protective plate 5 and the connecting shaft 4 are rotated and unfolded under the action of the torsion spring 11 to expose the socket 2. At this time, the connector can be docked normally. When the protective plate 5 is unfolded, it also plays a role in preventing accidental touch, optimizing the protection effect, and when it needs to be covered again When the socket 2 is opened, the protection plate 5 is rotated back. At this time, the protection plate 5 drives the connecting shaft 4 to rotate inside the overlap block 3, and then the torsion spring 11 is stretched again. When the end of the protection plate 5 contacts the block 8, the block 8 moves downward. At this time, the block 8 drives the limit block 9 to slide inside the fixed block 7. At this time, the limit block 9 will squeeze the first spring 10. When the block 8 and the slot 6 are in the same vertical direction, the block 8 enters the slot 6 under the action of the limit block 9 and the first spring 10. At this time, the protection plate 5 is in a state of covering the socket 2 again, so that dust will not enter the socket 2.

[0024] Embodiment 2: Different from Embodiment 1, by providing a pressurized fixing assembly, the plug-in component can be supported by the fixing plate 14 when working, thereby ensuring the working stability of the plug-in component. Figure 6 and Figure 7 As shown: The pressurized fixing assembly also includes a baffle 12 fixedly connected to the end of the connecting shaft 4 , and an upper connecting rod 15 is attached to the outer wall of the baffle 12 , and the lower surface of the upper connecting rod 15 is fixedly connected to the upper surface of the fixing plate 14 .

[0025] The limit rod 13 is an inverted "L" structure when viewed from above, and a second spring 16 that plays an elastic reset role is fixedly connected to the surface of the limit rod 13, and the other side of the second spring 16 is fixedly connected to the surface of the fixed plate 14, and the second spring 16 is initially in a compressed state, the fixed plate 14 is symmetrically distributed about the center of the socket 2, and the surface of the fixed plate 14 is inclined.

[0026] When the protective plate 5 covers the socket 2, the baffle 12 and the upper connecting rod 15 are in contact, and the baffle 12 supports the upper connecting rod 15. At this time, the fixing plate 14 and the limiting rod 13 cooperate to squeeze the second spring 16, and when the protective plate 5 and the connecting shaft 4 rotate, the baffle 12 rotates synchronously, and the upper connecting rod 15 and the fixing plate 14 will not be squeezed. At this time, the fixing plate 14 moves toward the direction of the socket 2 under the action of the limiting rod 13 and the second spring 16. At this time, the plug-in part can be directly docked. Since the surface of the fixing plate 14 is inclined, the fixing plate 14 will be pushed by the plug-in part and move in the direction of squeezing the second spring 16. After the plug-in part is normally docked to the inside of the socket 2, the fixing plates 14 on the left and right sides will always have a tendency to move toward the socket 2 under the action of the second spring 16, that is, the fixing plate 14 supports the plug-in part, which plays a role in fixing the plug-in part, making the plug-in part work more stably.

[0027] Embodiment 3: Different from Embodiment 2, by setting a dust cleaning component, dust will not remain on the surface of the air permeable net 17, thus ensuring the normal operation of the air permeable net 17. Figure 8 and Fig. 9 As shown: The cleaning assembly also includes an external rod 23 fixedly connected to the outer wall of the fixed plate 14, and the surface of the external rod 23 is convex, and a second magnet 25 is fixedly connected to the inner wall of the external rod 23, the end of the guide rod 18 is fixedly connected to the connecting plate 19, and the inner wall of the heater body 1 is fixedly connected to the air permeable net 17.

[0028] The surface of the guide rod 18 is movably connected to a movable plate 21, and a first magnet 24 is fixedly connected to the outer wall of the movable plate 21, and the magnetic poles on the surface of the first magnet 24 are opposite to the magnetic poles on the surface of the second magnet 25, and the second magnets 25 are evenly spaced on the inner wall of the external rod 23. The surface of the movable plate 21 is fixedly connected to a third spring 20 that plays an elastic reset role, and the other side of the third spring 20 is fixedly connected to the inner wall of the connecting plate 19, and a through hole is opened on the surface of the movable plate 21.

[0029] When the inner fixed plate 14 moves, it will drive the external rod 23 to move synchronously, and when the external rod 23 moves, the second magnet 25 will approach the first magnet 24 in sequence, and when the second magnet 25 approaches the first magnet 24, the movable plate 21 moves away from the heater body 1 under the action of the mutual magnetic force. At this time, the movable plate 21 cooperates with the connecting plate 19 to squeeze the third spring 20, and when the second magnet 25 is away from the first magnet 24, the movable plate 21 returns to its original position under the action of the third spring 20, that is, the movable plate 21 will make reciprocating linear motion in the vertical direction under the action of the mutual magnetic force, the guide rod 18, the connecting plate 19 and the third spring 20, and then the movable plate 21 will drive the striking rod 22 to strike the outer wall of the air permeable net 17 again and again to make the dust fall off, so that the air permeable net 17 can work normally, thereby ensuring the normal heat dissipation effect of the heater body 1, and the through holes on the surface of the movable plate 21 will not affect the exchange of internal and external air.

[0030] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
