[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0042] refer to Figure 1-10 A specific embodiment of this utility model provides a car that simulates a car crash, including a body 4, a seat 7, and a floor 8 installed sequentially from top to bottom, and also includes:
[0043] The second sliding plate 902 is slidably connected between the seat plate 7 and the floor plate 8 along the driving direction. By sliding the second sliding plate 902, the tailgate 5 at the rear of the vehicle body 4 and the doors 3 on both sides of the vehicle body 4 can be opened or closed.
[0044] The first sliding plate 901 is slidably connected to the bottom of the second sliding plate 902 along the driving direction. The front end 1 of the vehicle is hinged to the forward end of the first sliding plate 901 and is engaged with the second sliding plate 902 by a spring 908 between the first sliding plate 901 and the second sliding plate 902. A torsion spring 905 is installed at the hinge point between the front end 1 and the first sliding plate 901.
[0045] Currently, there are various remote-controlled cars, pullback cars, pushcarts, and transforming cars on the market, but basically none of them can effectively educate children about safety, and they lack entertainment value. In this application, the main function of the spring 908 is to engage the car head 1 with the second sliding plate 902; the main function of the first sliding plate 901 is to connect the car head 1 and push the second sliding plate 902, thereby opening the tailgate 5 and the door 3; the main function of the torsion spring 905 is to push the car head 1 to rotate a certain angle when it disengages from the second sliding plate 902; when the car is in normal condition, the car head 1 is engaged with the second sliding plate 902 by the elastic force of the spring 908, the torsion spring 905 is in a compressed state, and the tailgate 5 and the door 3 are both closed; when the car head 1 collides, the car head 1 pushes the first sliding plate 902. When the first sliding plate 901 momentarily compresses the spring 908, the front of the car 1 moves relative to the second sliding plate 902 in the reverse direction. The front of the car 1 and the second sliding plate 902 disengage. Under the action of the torsion spring 905, the front of the car 1 rotates a certain angle around the forward end of the first sliding plate 901, causing it to tilt. When the first sliding plate 901 overcomes the elastic force of the spring 908 and pushes the second sliding plate 902 to move in the reverse direction, the second sliding plate 902 causes the tailgate 5 and the door 3 to open, thus demonstrating the deformed state of the car after a collision. When the front of the car 1, the first sliding plate 901, and the second sliding plate 902 are moved in the opposite direction, the car returns to its normal state. Overall, this utility model can produce a collision deformation effect, achieving the purpose of educating children about safety, while also enhancing the fun.
[0046] In this application, the driving direction refers to the forward or reverse direction of the car.
[0047] Further optimizations to the plan include:
[0048] The first limiting groove 907 is formed on the bottom side of the second sliding plate 902. The middle end of the first sliding plate 901 is slidably connected in the first limiting groove 907 along the driving direction. The spring 908 is located in the first limiting groove 907 and abuts between the forward side of the first sliding plate 901 and the backward side of the second sliding plate 902.
[0049] Under normal circumstances, the middle end of the first sliding plate 901 is located between the forward side and the reverse side of the first limiting groove 907 under the action of the spring 908. When the car collides, the front of the car 1 pushes the first sliding plate 901 to slide in the first limiting groove 907 and overcomes the elastic force of the spring 908. When the first sliding plate 901 contacts the reverse side in the first limiting groove 907, it pushes the second sliding plate 902 to move synchronously in the reverse direction, thereby achieving the purpose of opening the tailgate 5 and the door 3.
[0050] Further optimizations to the plan include:
[0051] Protrusion 101 is fixedly connected to the inner side wall of the front of the vehicle 1;
[0052] A through hole 906 is provided at the forward end of the second sliding plate 902. A protrusion 101 is located inside the through hole 906 and is abutted against the forward side inside the through hole 906 by a spring 908.
[0053] Under normal circumstances, the end of the protrusion 101 away from the inner wall of the front of the vehicle 1 is located in the through hole 906 and abuts against the forward side of the through hole 906 under the action of the spring 908. When the vehicle collides, the front of the vehicle 1 pushes the first sliding plate 901 to move, causing the protrusion 101 to disengage from the forward side of the through hole 906. Under the action of the torsion spring 905, the front of the vehicle 1 rotates around the forward end of the first sliding plate 901 by a certain angle and tilts, causing the protrusion 101 to completely disengage from the through hole 906. When the first sliding plate 901 moves in the forward direction (which can be achieved by manually pulling the front of the vehicle 1), the front of the vehicle 1 is manually pressed and the elastic force of the torsion spring 905 is overcome, causing the protrusion 101 to re-enter the through hole 906. Through the elastic force of the spring 908, the protrusion 101 abuts against the forward side of the through hole 906 again.
[0054] Further optimizations to the plan include:
[0055] The front wheel frame 601 is vertically rotatably connected to the inner wall of the vehicle body 4. The front wheel 6 is mounted on the front wheel frame 601. The door 3 rotates synchronously on the vehicle body 4 with the front wheel frame 601 on the same axis.
[0056] Link 301 is fixedly connected to the circumference of the rotating part of the door 3. The bottom of the centrifugal end of the link 301 is located in the second limiting groove 909 on the second sliding plate 902. The open or closed states of the two sets of doors 3 correspond to the inward or parallel states of the two sets of front wheels 6.
[0057] Under normal circumstances, the two sets of front wheels 6 are in a parallel state, and the two sets of doors 3 are in a closed state. Since the doors 3 and the front wheel frame 601 are coaxially and synchronously rotated, when the second sliding plate 902 moves in the reversing direction, the side wall of the second limiting groove 909 pushes the bottom of the centrifugal end of the connecting rod 301 to move, thereby causing the doors 3 and the front wheel frame 601 to rotate synchronously on the body 4, so that the two sets of doors 3 open and the two sets of front wheel frames 601 drive the front wheels 6 to form an inward V-shape; at the same time, the second sliding plate 902 pushes the tailgate 5 to rotate and open; when the second sliding plate 902 moves in the forward direction (which can be achieved by manually pulling the front of the car 1 and the first sliding plate 901), the two sets of doors 3 close, the two sets of front wheels 6 return to a parallel state, and the tailgate 5 closes.
[0058] Further optimizations to the plan include:
[0059] The first fixed support point 501 is fixedly connected to the tailgate 5 and rotatably connected to the seat plate 7.
[0060] The U-shaped groove 502 is formed on the first fixed support point 501, and the fixed rod 904 on the reversing end of the second sliding plate 902 is slidably engaged in the U-shaped groove 502.
[0061] The opening of the U-shaped groove 502 is located away from the rotation center of the first fixed fulcrum 501. When the second sliding plate 902 moves in the reversing direction, it will drive the fixed rod 904 to slide in the U-shaped groove 502 and push the inner wall of the U-shaped groove 502, causing the first fixed fulcrum 501 to rotate. Thus, the first fixed fulcrum 501 drives the tailgate 5 to rotate and open. When the second sliding plate 902 moves in the forward direction, the tailgate 5 closes.
[0062] Further optimizations to the plan include:
[0063] The rotating groove 701 is located at the bottom of the seat plate 7 along the driving direction. The wheel axle 11 of the rear wheel 10 is perpendicular to the rotating groove 701 and is rotatably connected in the rotating groove 701. The rear wheel 10 is driven to rotate around the rotating groove 701 by sliding the second sliding plate 902 along the driving direction.
[0064] In normal condition, the two sets of rear wheels 10 are parallel; fixed shafts are symmetrically fixed to both sides of the wheel axle 11, and the two sets of fixed shafts are located in the rotating groove 701 respectively, and rotate in cooperation with the rotating groove 701; the second sliding plate 902 slides in the reversing direction, thereby driving the rear wheel 10 to rotate around the rotating groove 701, so that the rear wheel 10 rotates around the rotating groove 701, that is, the bottom of the rear wheel 10 rotates towards the vehicle floor plate 8 at a certain angle.
[0065] Further optimizations to the plan include:
[0066] An arc-shaped groove 903 is formed on the vertical side wall of the second sliding plate 902, and the end of the wheel axle 11 away from the rear wheel 10 is slidably connected in the arc-shaped groove 903.
[0067] The end of the wheel axle 11 is located in the arc groove 903. When the second sliding plate 902 slides in the reversing direction, the side wall of the arc groove 903 pushes the end of the wheel axle 11 to slide along the arc groove 903, thereby realizing the rotation of the rear wheel 10 around the rotating groove 701 and the bottom of the rear wheel 10 rotates towards the vehicle floor 8 at a certain angle. When the second sliding plate 902 moves in the forward direction, the side wall of the arc groove 903 pushes the end of the wheel axle 11 to slide along the arc groove 903, and the wheel axle 11 and the rear wheel 10 return to normal.
[0068] Further optimization of the design includes the following front hood assembly 2 located above the front of the vehicle 1:
[0069] The first cover plate 201 and the second cover plate 202 are rotatably connected;
[0070] The second fixed support point 2021 is fixedly connected to the second cover plate 202 and is rotatably connected to the seat plate 7.
[0071] When the car is in normal condition, the first cover plate 201 and the second cover plate 202 are flat. When the front of the car 1 is hit and rotated by a certain angle, the first cover plate 201 and the second cover plate 202 are lifted up, causing the first cover plate 201 and the second cover plate 202 to rotate by a certain angle, mimicking the deformation of the front cover plate assembly 2. When the front of the car 1 returns to normal condition, the first cover plate 201 and the second cover plate 202 are manually pressed to restore the flat state.
[0072] Further optimizations to the plan include:
[0073] Protrusion 602 is fixedly connected to the edge of the rotating connection of the door 3;
[0074] The groove 603 is formed on the edge of the rotating connection of the front wheel frame 601 and is adapted to the protrusion 602.
[0075] The engagement between the protrusion 602 and the groove 603 allows the door 3 and the front wheel frame 601 to rotate synchronously on the body 4, coaxially.
