DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment

[0021] As Figure 1 、 Figure 2 and Figure 3 As shown in, a carriage door for a rescue fire truck proposed in an embodiment of the present invention includes a door body 1 and a door frame 5 for installing the door body 1. The door frame 5 is fixedly connected to the vehicle body 11, and two symmetrically distributed lifting drive components 10 are installed inside the vehicle body 11. The lifting drive component 10 includes a protective frame 1001 fixedly connected to the vehicle body 11. A T-shaped groove 1002 is provided on the protective frame 1001 along the length direction of the protective frame 1001, and a T-shaped slider 1003 is slidably connected to the T-shaped groove 1002 of the protective frame 1001. One side of the door body 1 is fixedly connected with support plates 8 distributed corresponding to the upper and lower positions. A support arm 9 is rotatably connected between the T-shaped slider 1003 and one of the bottom support plates 8. Track grooves 3 are provided on both sides of the door frame 5, and sliding blocks 2 are slidably connected to the track grooves 3 of the door frame 5. Both sides of the door body 1 are rotatably connected to the corresponding sliding blocks 2.

[0022] It should be noted that the door frame 5 is fixedly connected to the vehicle body 11 for installing the door body 1. By providing a track groove 3 on the door frame 5 and sliding a sliding block 2 in the track groove 3, and rotatably connecting both sides of the door body 1 to the corresponding sliding blocks 2, a part of the door body 1 can move up and down. By installing a lifting drive component 10 on the vehicle body 11, the lifting drive component 10 is composed of a protective frame 1001 and a T-shaped slider 1003 slidably connected to the protective frame 1001. By providing support plates 8 distributed corresponding to the upper and lower positions on one side of the door body 1, a support arm 9 is rotatably connected between the T-shaped slider 1003 and one of the bottom support plates 8. When the position of the T-shaped slider 1003 moves upward, the door body 1 can be supported by the support arm 9, and then a part of the door body 1 moves along the track groove 3 to adjust the closing state of the door body 1. This method can realize the rapid opening and closing of the door body 1, reduce the time, and is beneficial to the development of fire rescue work. When the door body 1 needs to be closed to the door frame 5, the movement of the T-shaped slider 1003 can be controlled in the reverse direction.

[0023] As Figure 1As shown, in some embodiments, two symmetrically distributed rotating seats 6 are installed on the door frame 5, and a connecting rod 7 is rotatably connected to the rotating seat 6 and a support plate 8 in the upper middle part thereof.

[0024] It should be noted that by rotatably connecting the connecting rod 7 to the rotating seat 6 and a support plate 8 in the upper middle part thereof, the connecting rod 7 can realize the lifting and limiting functions of the upper part of the door body 1. When the T-shaped slider 1003 moves upward, the support arm 9 flips to support the door body 1. The sliding blocks 2 on both sides of the door body 1 slide at the track groove 3, causing the door body 1 to fold, and during the folding process, it moves upward. At the same time, the connecting rod 7 folds to perform the lifting function of the upper part of the door body 1, and then the door body 1 is horizontally closed to the upper inner side of the vehicle body 11. This method can realize the stable opening and closing of the door body 1, and the opening and closing speed is fast, which is beneficial to the quick extraction of fire-fighting equipment and facilitates the development of rescue work. It should also be noted that a total of four support plates 8 are provided, and the four support plates 8 are symmetrically distributed to respectively realize the connection of the corresponding connecting rod 7 and support arm 9.

[0025] As Figure 1 and Figure 2 shown, in some embodiments, the protective frame 1001 is vertically fixedly connected to the vehicle body 11.

[0026] It should be noted that by vertically fixedly connecting the protective frame 1001 to the vehicle body 11, the T-shaped slider 1003 can be vertically lifted and lowered, and then the support arm 9 can be quickly flipped, making the support movement of the door body 1 more stable.

[0027] As Figure 2 shown, in some embodiments, a lead screw 1004 is rotatably connected to the T-shaped groove 1002 of the protective frame 1001. The T-shaped slider 1003 is provided with a threaded hole adapted to the lead screw 1004 at the corresponding position of the lead screw 1004, and a motor 1005 for driving the rotation of the lead screw 1004 is installed on one side of the protective frame 1001.

[0028] It should be noted that by rotatably connecting the lead screw 1004 to the T-shaped groove 1002 of the protective frame 1001 and the T-shaped slider 1003 is threadedly connected to the lead screw 1004, when the lead screw 1004 rotates, the T-shaped slider 1003 can slide on the T-shaped groove 1002 to realize the control function of the movement of the T-shaped slider 1003. By installing the motor 1005 on one side of the protective frame 1001, the motor 1005 can drive the rotation of the lead screw 1004 to realize the movement control of the T-shaped slider 1003. When the motor 1005 rotates in the reverse direction, the T-shaped slider 1003 moves in the reverse direction.

[0029] As Figure 1 and Figure 3 shown, in some embodiments, a sealing baffle 4 is fixedly connected to the upper part of the door frame 5.

[0030] It should be noted that the setting of the sealing baffle 4 can achieve the protective sealing effect on the upper part of the door frame 5, avoid the insufficient sealing of the door body 1 of the box, and then ensure the sealing protection of the vehicle body 11.

[0031] The working principle and usage steps of the present utility model are as follows: When it is necessary to open the door body 1 of the box and then take out the fire-fighting equipment, control the motor 1005 to work. The motor 1005 drives the lead screw 1004 to rotate, so that the T-shaped slider 1003 moves upward at the T-shaped groove 1002 of the protective frame 1001, and then the support arm 9 is folded. The door body 1 of the box is supported by the support arm 9. At this time, the door body 1 of the box receives the supporting force of the support arm 9, and then the sliding blocks 2 on both sides of the door body 1 of the box slide on the track groove 3 of the door frame 5. During the upward movement, the connecting rod 7 can lift and limit the door body 1 of the box. When the T-shaped slider 1003 continues to move upward, the door body 1 of the box is folded, and the door body 1 of the box tends to be horizontal. The door body 1 of the box is horizontally closed to the upper inner side of the vehicle body 11. When it is necessary to close the door body 1 of the box, control the motor 1005 to work in the reverse direction, and then the T-shaped slider 1003 moves downward. The door body 1 of the box is pulled by the action of the support arm 9, and the connecting rod 7 pulls and limits the upper part of the door body 1 of the box, and then the door body 1 of the box is closed to the door frame 5.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
