[0041] Example 1

[0042] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a dump truck frame, the device comprising,

[0043] The mounting mechanism 100 includes a frame 101, a mounting plate 102 fixedly connected to the top of the frame 101, and a mounting frame 103 fixedly connected to the inner side of the mounting plate 102. Heat dissipation grooves 104 are provided on both sides and the bottom of the mounting frame 103. Protective frames 105 are fixedly connected to the other two sides of the mounting frame 103. A triggering component 106 is adapted to be installed inside the protective frame 105.

[0044] The top of the protective frame 105 is provided with a sliding groove 105a;

[0045] The fixing mechanism 200 includes a lead screw 201 rotatably connected inside the protective frame 105, a first bevel gear 202 fixedly connected to one end of the lead screw 201, and a connecting rod 203 rotatably connected inside the protective frame 105. A second bevel gear 204 is fixedly connected to one end of the connecting rod 203, and a push block 205 is fixedly connected to the outside of the connecting rod 203.

[0046] The protective frame 105 has a pressing component 206 inside, a transmission component 207 inside, a clamping component 208 inside, and a locking component 209 at the top.

[0047] Specifically, the triggering component 106 includes a rotating rod 106a rotatably connected inside the protective frame 105, a roller 106b fixedly connected to the outside of the rotating rod 106a, and a drive bevel gear 106c fixedly connected to the outside of the roller 106b, and the drive bevel gear 106c is provided in two sets.

[0048] Furthermore, the clamping component 206 includes a mounting block 206a threadedly connected to the lead screw 201, a slider 206b fixedly connected to the outside of the mounting block 206a, and a connecting plate 206c slidably connected to the mounting block 206a. A stop bar 206d is slidably connected to the bottom end of one side of the connecting plate 206c.

[0049] The outer surface of the baffle 206d is provided with a groove.

[0050] Preferably, the clamping component 206 further includes a pressure plate 206e fixedly connected to the top of the connecting plate 206c, a pressure block 206f fixedly connected to the bottom of the pressure plate 206e, and a locking block 206g fixedly connected to the bottom of the pressure plate 206e. The locking block 206g has a first positioning groove 206h on its outer side, and the mounting block 206a has a restoration component 206i inside.

[0051] It should be noted that the restoration component 206i includes a sliding sleeve 206i-1 fixedly connected to the top of the mounting block 206a, a sliding rod 206i-2 slidably connected to the inside of the sliding sleeve 206i-1, and a fixing block 206i-3 fixedly connected to the bottom of the sliding rod 206i-2. One side of the fixing block 206i-3 is fixedly connected to the connecting plate 206c.

[0052] The sliding sleeve 206i-1 has a first spring 206i-4 inside.

[0053] During use, when installing the battery M, it is first necessary to insert the battery M into the mounting frame 103. Simultaneously, the two sides of the battery M press against the roller 106b, causing the roller 106b to rotate via the rotating rod 106a. This rotation drives the two sets of active bevel gears 106c to rotate. The rotation of the two sets of active bevel gears 106c drives the first bevel gear 202 and the second bevel gear 204 to rotate respectively. The rotation of the first bevel gear 202 simultaneously drives the lead screw 201 to rotate, causing the mounting block 206a to slide on the top of the protective frame 105 via the slider 206b, thereby allowing the connecting plate 206c to move. The pressure plate 206e slides towards the battery M. After the surface of the battery M is fully inserted into the interior of the mounting frame 103, the battery M is pressed down. At this time, the pressure plate 206e will drive the pressure block 206f to slide above the battery M. In conjunction with the second bevel gear 204 driving the push block 205 to rotate through the connecting rod 203, the push block 205 will press the stop bar 206d downward. As the stop bar 206d slides down, the connecting plate 206c and the pressure plate 206e slide down, causing the pressure block 206f to slide down. The sliding pressure block 206f then squeezes and fixes the battery M, thus initially fixing the battery M in the mounting frame 103.

[0054] As the connecting plate 206c slides down, it drives the sliding rod 206i-2 to slide inside the sliding sleeve 206i-1 through the fixing block 206i-3, and stretches the first spring 206i-4.

[0055] In summary, when the battery M is pressed into the mounting frame 103, the pressure plate 206e and the pressure block 206f will first move to the top of the battery M and then slide downwards, thereby initially squeezing and fixing the battery M, thus ensuring the stability of the battery M after it is installed inside the mounting frame 103.

[0056] Example 2

[0057] Reference Figures 1-8This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the transmission component 207 includes a support frame 207a fixedly connected to the outside of the mounting frame 103, a pressure rod 207b slidably connected inside the support frame 207a, and a hinge block 207c fixedly connected to the bottom end of the pressure rod 207b. The pressure rod 207b has a friction groove 207d inside and a slot 207e inside. The bottom end of the slot 207e has a second positioning groove 207f.

[0058] Furthermore, the clamping component 208 includes a guide rod 208a fixedly connected inside the protective frame 105, a guide block 208b slidably connected to the outside of the guide rod 208a, and a hinge plate 208c hinged to the top of the guide block 208b.

[0059] The guide rod 208a is fitted with a second spring 208d on its outer side, and the other end of the hinge plate 208c is hinged to the hinge block 207c.

[0060] Furthermore, the clamping component 208 also includes a long plate 208e fixedly connected to one end of the guide block 208b, and a fixing plate 208f fixedly connected to the outside of the long plate 208e.

[0061] The fixed plate 208f is shaped like an "L".

[0062] During use, as the pressure plate 206e slides towards the battery M, the locking block 206g is inserted into the slot 207e. As the pressure plate 206e slides down, the pressure rod 207b slides downward under pressure. With the design of the hinge plate 208c, the guide block 208b slides on the outside of the guide rod 208a and compresses the second spring 208d, causing it to extend and retract. While the guide block 208b slides, it drives the fixing plate 208f to slide through the long plate 208e. With the special shape design of the fixing plate 208f, the fixing plate 208f can press and fix the battery M from the side, further ensuring the stability of the battery M after installation.

[0063] As the pressure rod 207b slides down, the friction groove 207d comes into contact with the surface of the rotating rod 106a. Under the action of friction, the rotating rod 106a cannot rotate, thus limiting and fixing the roller 106b, further improving the stability of the battery M after it is fixed.

[0064] In summary, while the pressure plate 206e and the pressure block 206f press and fix the battery M downwards, they also drive the two sets of fixing plates 208f to press and fix the battery M relative to each other, thereby effectively ensuring the stability of the battery M after installation. Furthermore, the roller 106b is limited to prevent it from rotating, further ensuring the firmness of the battery M after installation.

[0065] Example 3

[0066] Reference Figures 1-9 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the locking component 209 includes a square block 209a fixedly connected to the top of the protective frame 105, a rotating shaft 209b rotatably connected inside the square block 209a, and a handle 209c fixedly connected to the top of the rotating shaft 209b.

[0067] Furthermore, the locking component 209 also includes a connecting plate 209d fixedly connected to the outside of the rotating shaft 209b, a connecting block 209e fixedly connected to the outside of the connecting plate 209d, and a hinge rod 209f hinged to the connecting block 209e.

[0068] The other end of the hinge rod 209f is hinged to a positioning rod 209g, and the positioning rod 209g is slidably connected to the square block 209a. A torsion spring 209h is provided inside the rotating shaft 209b.

[0069] During use, after the locking block 206g is inserted into the slot 207e, the first positioning slot 206h and the second positioning slot 207f will be aligned. At this time, after the pressure rod 207b slides down, it will drive the first positioning slot 206h and the second positioning slot 207f to slide to the surface of the positioning rod 209g. At this time, the force of the positioning rod 209g being squeezed by the surface of the pressure rod 207b is released. Then, under the elasticity of the torsion spring 209h inside the rotating shaft 209b, the rotating shaft 209b will be driven to rotate. This will cause the connecting plate 209d to drive the connecting block 209e to rotate. With the design of the hinge rod 209f, the positioning rod 209g will be driven to slide outward and insert into the first positioning slot 206h and the second positioning slot 207f, so that the positioning rod 209g is engaged with the first positioning slot 206h and the second positioning slot 207f, thereby completing the installation of the battery M and ensuring the stability and firmness of the battery M after installation.

[0070] When it is necessary to remove the battery M, by rotating the reverse handle 209c, the positioning rod 209g will be driven away from the first positioning groove 206h and the second positioning groove 207f through the rotating shaft 209b. At this time, the limit on the pressure rod 207b is released, and the elasticity of the second spring 208d will drive the pressure rod 207b to slide upward and reset. At this time, the battery M can be removed by pulling it upward.

[0071] In summary, during actual operation, simply pressing down on battery M completes the installation of battery M and ensures the stability of the battery M installation. After turning handle 209c, pulling up on battery M completes the removal of battery M. The operation is simple and quick, reducing the labor intensity of personnel installing battery M while ensuring the stability and firmness of battery M installation.
