Description

Technical Field

[0001] This utility model relates to the field of electric vehicle fixing device technology, and in particular to a shock-absorbing electric vehicle battery fixing device. Background Technology

[0002] With the rapid development of society and the economy, people have a variety of transportation options. In recent years, electric vehicles have been hailed as one of the most popular and commonly used modes of transportation. A three-wheeled electric vehicle sold on the market consists of a frame, wheels, a seat, and a handlebar. The condition of the battery directly determines the lifespan of the electric vehicle.

[0003] Currently, the batteries in electric vehicles are usually placed in a compartment under the seat, with little to no secure fixing. This makes them susceptible to vibration during use, especially on rough or uneven surfaces, which can cause significant damage to the battery. This not only reduces battery lifespan but also poses a serious safety hazard to riders, as the vibrating environment can lead to battery explosions. Therefore, a shock-absorbing battery fixing device for electric vehicles has been proposed for improvement and upgrading. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing battery fixing device for electric vehicles to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] Design a shock-absorbing battery fixing device for electric vehicles, including a placement box, a cover plate on the top of the placement box and heat dissipation grooves on both sides of the outer wall of the placement box, a placement plate inside the placement box, a fixing component on the top of the placement plate and a buffer component below the placement plate.

[0007] Furthermore, guide grooves are provided on both the front and rear sides of the inner wall of the placement box, and guide blocks are symmetrically arranged on both the front and rear sides of the placement plate, with the guide blocks slidably connected inside the guide grooves. The fixing assembly includes a mounting bracket, a small motor, and a bidirectional lead screw. There are two mounting brackets, with the small motor fixedly installed inside the right mounting bracket.

[0008] Furthermore, the output end of the small motor is connected to a bidirectional lead screw, and two sets of limiting blocks are provided on the front side of the bidirectional lead screw. Both sets of limiting blocks are fixedly connected to the outer walls of the two guide plates. The two sets of limiting blocks are respectively provided on the outer walls of the bidirectional lead screw and the slide bar, and one of the limiting blocks is threadedly connected to the bidirectional lead screw.

[0009] Furthermore, each of the two guide plates has several buffer springs on its outer wall, and one end of each buffer spring is connected to the anti-slip clamping plate. The upper surface of the placement plate is provided with a movable groove, and the lower end of each guide plate is symmetrically provided with movable blocks, which are slidably connected inside the movable groove.

[0010] Furthermore, the buffer assembly includes a positioning slide rail, a baffle, and a connecting seat. There are two positioning slide rails, and baffles are provided at both ends of the positioning slide rails. There are four connecting seats, and each connecting seat has a slot at its lower end, which is slidably connected to the positioning slide rail. A damping rod is fixedly provided on the outer wall of the baffle, and a return spring is sleeved on the outer wall of the damping rod.

[0011] Furthermore, one end of the damping rod is connected to the connecting seat, a connecting shaft is fixedly installed inside the connecting seat, and a guide frame is rotatably installed on the outer wall of the connecting shaft. The other end of the guide frame is rotatably installed inside the positioning block, and the upper end of the positioning block is connected to the bottom of the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model device is equipped with components such as positioning slide rail, baffle, connecting seat, guide frame, positioning block, damping rod, and return spring. The placement plate presses against the four positioning blocks at the bottom, causing the four positioning blocks to drive one end of the guide frame to move on the outer wall of the connecting shaft on the four connecting seats. As a result, the bottom groove of the connecting seat slides on the positioning slide rail, thereby pressing against the damping rod on the baffle. At the same time, a return spring is sleeved on the outer wall of the damping rod for cooperating compression, which facilitates effective shock absorption and buffering when the battery shakes on the placement plate, thereby improving the service life of the battery.

[0014] 2. This utility model device includes a placement plate, mounting frame, small motor, bidirectional lead screw, guide plate, anti-slip clamping plate, buffer spring, and other components. The small motor drives the bidirectional lead screw to rotate, which in turn drives the guide plates connected to the two limit blocks on the outer wall to move relative to each other. This causes the anti-slip clamping plates on the two guide plates to move relative to each other, clamping and fixing electric vehicle batteries of different sizes. At the same time, the buffer spring is provided to protect the battery during clamping. This facilitates the fastening of batteries of different sizes, improves the stability of battery installation, and has a simple structure.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 5 As shown in the figure, this embodiment provides a shock-absorbing battery fixing device for electric vehicles, including a placement box 1, a cover plate 2 on the top of the placement box 1, and heat dissipation grooves 3 on both sides of the outer wall of the placement box 1. A placement plate 4 is provided inside the placement box 1, a fixing component 5 is provided above the placement plate 4, and a buffer component 6 is provided below the placement plate 4.

[0025] Preferably, guide grooves 7 are provided on both the front and rear sides of the inner wall of the placement box 1, and guide blocks 71 are symmetrically arranged on both the front and rear sides of the placement plate 4, with the guide blocks 71 slidably connected inside the guide grooves 7. The fixing assembly 5 includes a mounting bracket 51, a small motor 52, and a double-acting screw 53. There are two mounting brackets 51, with the small motor 52 fixedly installed inside the right mounting bracket 51. Guide grooves 7 are provided on both the front and rear sides of the inner wall of the placement box 1, and guide blocks 71 are symmetrically arranged on both the front and rear sides of the placement plate 4, with the guide blocks 71 slidably connected inside the guide grooves 7. Inside the guide groove 7, the fixing component 5 includes a mounting bracket 51, a small motor 52, and a two-way lead screw 53. There are two mounting brackets 51, and the small motor 52 is fixedly installed inside the right mounting bracket 51. Several buffer springs 59 are provided on the outer walls of the two guide plates 55, and one end of each buffer spring 59 is connected to the anti-slip clamping plate 591. The upper surface of the placement plate 4 is provided with a movable groove 58. Movable blocks 57 are symmetrically arranged at the lower end of the guide plates 55, and the movable blocks 57 are slidably connected inside the movable groove 58.

[0026] The small motor 52 inside the drive mounting bracket 51 drives the bidirectional lead screw 53 to rotate. Then, the bidirectional lead screw 53 drives the guide plates 55 connected by the two limit blocks 56 on the outer wall to move relative to each other. At the same time, the other side of the guide plate 55 uses the limit block 56 to slide on the slide rod 54, so that the anti-slip clamping plates 591 on the two guide plates 55 move relative to each other to clamp and fix electric vehicle batteries of different sizes. At the same time, a buffer spring 59 is set to protect the battery when clamping.

[0027] Preferably, the buffer assembly 6 includes a positioning slide rail 61, a baffle 62, and a connecting seat 63. There are two positioning slide rails 61, and baffles 62 are provided at both ends of the positioning slide rails 61. There are four connecting seats 63, and each connecting seat 63 has a slot 66 at its lower end, and the slot 66 is slidably connected to the positioning slide rail 61. A damping rod 68 is fixedly provided on the outer wall of the baffle 62, and a return spring 69 is sleeved on the outer wall of the damping rod 68. One end of the damping rod 68 is connected to the connecting seat 63. A connecting shaft 64 is fixedly provided inside the connecting seat 63, and a guide frame 65 is rotatably installed on the outer wall of the connecting shaft 64. The other end of the guide frame 65 is rotatably installed inside the positioning block 67, and the upper end of the positioning block 67 is connected to the bottom of the placement plate 4.

[0028] The shaking caused by the battery drives the placement plate 4 to move inside the guide groove 7 using the guide block 71. Then, the placement plate 4 presses against the four positioning blocks 67 at the bottom, causing the four positioning blocks 67 to drive one end of the guide frame 65 to move on the outer wall of the connecting shaft 64 on the four connecting seats 63. As a result, the bottom slot 66 of the connecting seat 63 slides on the positioning slide rail 61, thereby pressing the damping rod 68 on the baffle 62. At the same time, a return spring 69 is sleeved on the outer wall of the damping rod 68 to cooperate in pressing, which facilitates effective shock absorption and buffering when the battery on the placement plate 4 shakes.

[0029] The working principle and process of this utility model are as follows: First, open the cover plate 2. The operator places the battery on the placement plate 4 inside the placement box 1. At this time, the small motor 52 inside the drive mounting bracket 51 drives the bidirectional lead screw 53 to rotate. Then, the bidirectional lead screw 53 drives the guide plates 55 connected by the two limit blocks 56 on the outer wall to move relative to each other. At the same time, the other side of the guide plate 55 uses the limit block 56 to slide on the slide rod 54, so that the anti-slip clamping plates 591 on the two guide plates 55 move relative to each other to clamp and fix electric vehicle batteries of different sizes. At the same time, a buffer spring 59 is set to facilitate the clamping of the battery. To protect the battery, the electric vehicle experiences relatively bumpy rides, causing the battery to shake. This causes the placement plate 4 to move within the guide groove 7 using the guide block 71. The placement plate 4 then presses against the four bottom positioning blocks 67, which in turn cause one end of the guide frame 65 to move on the outer wall of the connecting shaft 64 on the four connecting seats 63. As a result, the bottom slot 66 of the connecting seat 63 slides on the positioning slide rail 61, thereby pressing against the damping rod 68 on the baffle 62. At the same time, a return spring 69 is fitted on the outer wall of the damping rod 68 to cooperate in the pressing, which effectively reduces and buffers the vibration of the battery on the placement plate 4, thus protecting it.
