Description

Technical Field

[0001] This utility model relates to the field of electric vehicle processing tools, and in particular to a convenient screw drill holder for assembling electric vehicle body structures. Background Technology

[0002] In the field of electric vehicle manufacturing, vehicle body assembly is one of the core processes, and its efficiency and precision directly affect the quality and production cost of the entire vehicle. As a commonly used fastening tool in the assembly process, the ease of access for screwdrivers is crucial to operational efficiency. Traditional screwdriver holders are mostly fixed structures, such as simple brackets or magnetic adsorption devices, which mainly rely on static support or magnetic adsorption to store tools. These holders are simple in structure and low in cost, and have certain applicability in static operation scenarios. However, with the development of more refined electric vehicle assembly processes, operators need to frequently switch between different sizes of screwdrivers and place higher demands on assembly precision (such as frame tube docking and component positioning), making the limitations of traditional holders increasingly apparent.

[0003] In existing technologies, although some screw drill holders have certain adjustment functions, the adjustment methods are mostly manual adjustment of the clamp width or replacement of special slots; for example, fixing U-shaped bayonets of different sizes with bolts, or using spring clips to achieve simple clamping; these adjustment methods have limited adaptability and require manual intervention, which is time-consuming and laborious; more importantly, traditional holders lack automatic locking and releasing mechanisms, and both hands are required to operate when picking up and putting down screw drills (one hand to fix the holder and the other hand to pick up the tool). In single-handed operation scenarios (such as when the operator needs to support vehicle parts at the same time), it is very easy for the tool to fall or for picking up and putting down to fail.

[0004] Therefore, to address the above problems, a convenient screw drill holder for electric vehicle body assembly is proposed. Through an automatic locking and releasing mechanism, it enables quick one-handed retrieval and placement. The screw drill can be quickly placed and retrieved with just one hand. During operation, one hand can assist in processing parts while the other hand quickly retrieves or stores the screw drill, improving work efficiency and convenience. Utility Model Content

[0005] To overcome the problem that traditional screw drill holders are prone to causing tools to fall or fail to be retrieved or placed when using them in the assembly of electric vehicle body structures in a one-handed operation scenario.

[0006] The technical solution of this utility model is as follows: a convenient screw drill holder for assembling electric vehicle body structures, comprising a fixed frame, an inclined slide groove, a guide rod, a sliding seat, a first return spring, an unfolding contact button, a locking contact button, and a locking assembly. An inclined slide groove is provided on one side of the fixed frame. A guide rod is provided on the inner side of the inclined slide groove. A sliding seat is slidably connected to the outer side of the guide rod. A first return spring is provided on the outer side of the guide rod. The two ends of the first return spring are connected to the sliding seat and the inner wall of the inclined slide groove. An unfolding contact button and a locking contact button are provided on the inner wall of the inclined slide groove. A locking assembly is provided on one side of the sliding seat. The locking assembly includes a fixed seat, a fixed tube, a worm gear, a grooved disc, a small slider, a large slider, a worm, and a first micro motor. A fixed seat is provided on one side of the sliding seat. A fixed tube is provided on the inner side of the fixed seat. A worm gear is rotatably connected to the outer side of the fixed tube. A grooved disc is fixedly connected to one side of the worm gear. A small slider is slidably connected within the multiple sets of grooves on the grooved disc. Multiple sets of large sliders are slidably connected to the inner side of the fixed seat. The large sliders and small sliders are rotatably connected. A worm that meshes with the worm gear is provided on the inner side of the fixed seat. A first micro motor is provided at one end of the worm.

[0007] Preferably, the spring's reset action causes the sliding seat and the unfolding contact button to contact when no screwdriver is placed. The unfolding contact button triggers the first micro-motor to rotate, driving the worm gear. The worm gear rotates, driving the worm wheel, which in turn rotates the grooved disc. The grooved disc rotates, causing the small slider to slide along the inner side of the grooved disc, thereby causing multiple sets of large sliders to slide along the fixed seat. These large sliders then unfold outwards around the center of the fixed seat. The operator places the screwdriver handle end against the fixed tube inside the fixed seat and applies a pushing force towards the lower end of the inclined groove, causing the sliding seat to slide diagonally downwards along the guide rod into contact with the locking contact button. This locks the screwdriver. The fixed contact button triggers the first micro motor to drive the worm gear in reverse, causing multiple sets of large sliders to retract inward and fix the handle end of the screw drill. After the operator releases the handle, the gravity of the screw drill is applied to the sliding seat, keeping the sliding seat in contact with the locking contact button and maintaining the screw drill in place. When the operator needs to remove the screw drill, they only need to pull the fixed screw drill with one hand to slide the sliding seat to the unfolding contact button end to remove the screw drill. This device can quickly place and retrieve the screw drill with only one hand. During operation, one hand can assist in processing the part while the other hand quickly picks up or stores the screw drill, improving work efficiency and convenience.

[0008] Preferably, a connecting frame is provided below the fixing frame, and a mounting frame is provided on one side of the connecting frame.

[0009] Preferably, the side of the mounting frame is provided with a connecting rod that passes through the mounting frame, and multiple placement slots are provided on the inner side of the mounting frame.

[0010] Preferably, multiple placement slots are arranged linearly, and a first magnetic block is provided on the inner side of the placement slot.

[0011] Preferably, a second micro motor is provided on one side of the fixed frame, a first lead screw is provided at the output end of the second micro motor, a first movable frame is threaded to the outer side of the first lead screw, and a third micro motor is provided above the first movable frame.

[0012] Preferably, the output end of the third micro motor is provided with a second lead screw, the outer side of which is threadedly connected to a second movable frame. A telescopic rod is provided on one side of the second movable frame, a first locking block is provided at one end of the telescopic rod, and a second return spring is provided on the outer side of the telescopic rod. The two ends of the second return spring are respectively connected to the first locking block and the second movable frame.

[0013] Preferably, a second block is provided below the first block, and a fixing rod is provided below the first block, passing through the second block. The second block and the fixing rod are slidably connected. A second magnetic block is provided below the first block, and a third magnetic block is provided above the second block. The opposing surfaces of the second and third magnetic blocks have opposite magnetic poles.

[0014] The beneficial effects of this utility model are: When no screwdriver is placed, the sliding seat and the unfolding contact button are engaged by the spring's reset action. The unfolding contact button triggers the first micro-motor to rotate, which in turn rotates the worm gear. The worm gear then rotates the worm wheel, which in turn rotates the grooved disc. This rotation causes the small slider to slide along the inner side of the grooved disc, thereby causing multiple sets of large sliders to slide along the fixed seat. These large sliders then unfold outwards around the center of the fixed seat. The operator places the screwdriver handle against the fixed tube inside the fixed seat and applies a pushing force towards the lower end of the inclined groove, causing the sliding seat to slide diagonally downwards along the guide rod into contact with the locking contact button. The button triggers the first micro-motor to drive the worm gear in reverse, causing multiple large sliders to retract inward and fix the handle end of the screw drill. After the operator releases the handle, the weight of the screw drill is applied to the sliding seat, keeping the sliding seat in contact with the locking contact button, thus maintaining the screw drill's fixation. When the operator needs to remove the screw drill, they only need to pull the fixed screw drill with one hand to slide the sliding seat to the unfolding contact button end to remove the screw drill. This device allows for quick placement and retrieval of the screw drill with only one hand. During operation, one hand can assist in processing the part while the other hand quickly picks up or stores the screw drill, improving work efficiency and convenience. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1 and Figure 2This utility model provides an embodiment: a convenient screw drill holder for assembling electric vehicle body structures, comprising a fixed frame 1, an inclined slide groove 2, a guide rod 3, a sliding seat 4, a first return spring 5, an unfolding contact button 6, a locking contact button 7, and a locking assembly. The fixed frame 1 has an inclined slide groove 2 on one side. A guide rod 3 is disposed inside the inclined slide groove 2. The sliding seat 4 is slidably connected to the outer side of the guide rod 3. The first return spring 5 is disposed outside the guide rod 3. Both ends of the first return spring 5 are connected to the sliding seat 4 and the inner wall of the inclined slide groove 2. An unfolding contact button 6 and a locking contact button 7 are disposed on the inner wall of the inclined slide groove 2. A lock is disposed on one side of the sliding seat 4. The fixing and locking components include a fixing seat 8, a fixing tube 101, a worm gear 102, a grooved disc 103, a small slider 104, a large slider 105, a worm 106, and a first micro motor 107. A fixing seat 8 is provided on one side of the sliding seat 4. A fixing tube 101 is provided inside the fixing seat 8. A worm gear 102 is rotatably connected to the outside of the fixing tube 101. A grooved disc 103 is fixedly connected to one side of the worm gear 102. Small sliders 104 are slidably connected within multiple sets of grooves in the grooved disc 103. Multiple sets of large sliders 105 are slidably connected to the inside of the fixing seat 8. The large sliders 105 and small sliders 104 are rotatably connected. A worm gear that meshes with the worm gear 102 is provided inside the fixing seat 8. 106. A first micro motor 107 is provided at one end of the worm gear 106. Through the reset action of the spring, when no screwdriver is placed, the sliding seat 4 and the unfolding contact button 6 are in contact. The unfolding contact button 6 triggers the first micro motor 107 to rotate, which drives the worm gear 106 to rotate. The rotation of the worm gear 106 drives the worm wheel 102 to rotate, which drives the grooved disc 103 to rotate. The rotation of the grooved disc 103 drives the small slider 104 to slide along the inner side of the grooved disc 103, thereby driving multiple sets of large sliders 105 to slide along the fixed seat 8. The multiple sets of large sliders 105 unfold outward with the center of the fixed seat 8 as the center. The operator places the handle end of the screwdriver against the fixed tube 10 inside the fixed seat 8. Inside the fixed tube 101, a thrust is applied to the lower end of the inclined slide groove 2, causing the sliding seat 4 to slide obliquely downward along the guide rod 3 into the inclined slide groove 2, so that the sliding seat 4 contacts the locking contact button 7. The locking contact button 7 triggers the first micro motor 107 to drive the worm gear 106 to reverse, causing multiple sets of large sliders 105 to retract inward, fixing the handle end of the screw drill. After the operator releases the handle, the gravity effect of the screw drill is applied to the sliding seat 4, keeping the sliding seat 4 in contact with the locking contact button 7, and continuously keeping the screw drill fixed. When the operator needs to remove the screw drill, he only needs to pull the fixed screw drill with one hand to slide the sliding seat 4 to the end of the unfolding contact button 6 to remove the screw drill.

[0018] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, a connecting frame 201 is provided below the fixing frame 1, a mounting frame 202 is provided on one side of the connecting frame 201, a connecting rod 203 is provided on the side of the mounting frame 202, the connecting rod 203 passes through the connecting frame 201, and multiple sets of placement slots 204 are provided on the inner side of the mounting frame 202. The multiple sets of placement slots 204 are arranged linearly, and a first magnetic block 205 is provided on the inner side of the placement slot 204. In use, by placing the drill bit of the screw drill into the placement slot 204, the drill bit is attracted and fixed in the placement slot 204 by the first magnetic block 205, which makes it convenient for the operator to store and retrieve the drill bit.

[0019] A second micro motor 301 is provided on one side of the fixed frame 1. A first lead screw 302 is provided at the output end of the second micro motor 301. A first movable frame 303 is threadedly connected to the outer side of the first lead screw 302. A third micro motor 304 is provided above the first movable frame 303. A second lead screw 305 is provided at the output end of the third micro motor 304. A second movable frame 306 is threadedly connected to the outer side of the second lead screw 305. A telescopic rod 307 is provided on one side of the second movable frame 306. A first locking block 308 is provided at one end of the telescopic rod 307. A second return spring 309 is provided on the outer side of the telescopic rod 307. The two ends of the second return spring 309 are respectively connected to the first locking block 308 and the second movable frame 306. A second locking block 310 is provided below the first locking block 308. A fixing rod 311 passing through the second locking block 310 is provided below the first locking block 308. Block 310 and fixing rod 311 are slidably connected. A second magnetic block 312 is provided below the first locking block 308, and a third magnetic block 313 is provided above the second locking block 310. The opposing surfaces of the second magnetic block 312 and the third magnetic block 313 have opposite magnetic poles. In use, the second micro motor 301 is started to drive the first lead screw 302 to rotate. The rotation of the first lead screw 302 drives the first moving frame 303 to move linearly. The third micro motor 304 is started to drive the second lead screw 305 to rotate. The rotation of the second lead screw 305 drives the second moving frame 306 to move up and down, thereby adjusting the position of the first locking block 308. By locking the first locking block 308 onto the electric vehicle frame tube, the adsorption between the second magnetic block 312 and the third magnetic block 313 closes the first locking block 308 and the second locking block 310, thus fixing the device onto the electric vehicle frame tube.

[0020] During operation, the second micro motor 301 is first started to drive the first lead screw 302 to rotate, which in turn drives the first moving frame 303 to move horizontally; the third micro motor 304 is started to drive the second lead screw 305 to rotate, which in turn drives the second moving frame 306 to move up and down, and the position of the first locking block 308 is adjusted to the electric vehicle frame tube. Through the attraction between the second magnetic block 312 and the third magnetic block 313, the first locking block 308 and the second locking block 310 are closed, and the mounting frame 202 is fixed to the frame. In the initial state, the first return spring 5 pushes the sliding seat 4 to the upper end of the inclined slide groove 2, triggering the unfolding contact button 6, which in turn triggers the first micro motor 107 to operate. The first micro motor 107 drives the worm gear 106 to rotate, which in turn drives the meshing worm wheel 102 and the grooved disc 103 to rotate. Small sliders 104 are slidably connected in the multiple grooves of the grooved disc 103. The small sliders 104 are connected to the large slider 105 through a rotating shaft. The large slider 105 slides along the inner side of the fixed seat 8. At this time, the large slider 105 unfolds outward with the center of the fixed seat 8 as the center, forming a space to accommodate the screw drill handle. The operator inserts the screw drill handle into the groove. The drill handle end is inserted into the fixing tube 101 inside the fixing seat 8, and the handle is pushed downward along the inclined slide groove 2, which drives the sliding seat 4 to slide along the guide rod 3 to the lower end of the inclined slide groove 2 until the sliding seat 4 contacts the locking contact button 7; the locking contact button 7 triggers the first micro motor 107 to reverse, the worm gear 106 drives the worm wheel 102 and the grooved disc 103 to rotate in the opposite direction, and the small slider 104 drives the large slider 105 to retract towards the center, clamping the screw drill handle; after the handle is released, the weight of the screw drill continues to press the locking contact button 7 through the sliding seat 4, maintaining the clamped state of the large slider 105, and realizing the stable fixation of the screw drill; When the screwdriver needs to be retrieved, the operator holds the screwdriver handle with one hand and pulls it upward, causing the sliding seat 4 to slide along the guide rod 3 towards the upper end of the inclined slide groove 2. After the sliding seat 4 disengages from the locking contact button 7, the first return spring 5 pushes the sliding seat 4 back to the position of the unfolding contact button 6, triggering the first micro motor 107 to run again. The large slider 105 unfolds outward to release the handle, allowing the screwdriver to be quickly retrieved. In addition, the placement slot 204 of the mounting bracket 202 attracts the screwdriver bit through the first magnetic block 205, facilitating temporary storage or classified management of different specifications of drill bits. If it is necessary to adjust the position of the mounting bracket 202 on the vehicle frame, the position of the first locking block 308 can be adjusted through the second micro motor 301 and the third micro motor 304 to ensure that the mounting bracket 202 is always close to the operating area, reducing the movement distance for retrieval and placement. This device, through the combination of mechanical transmission and magnetic fixation, realizes the quick retrieval and placement of the screwdriver with one hand, significantly improving the efficiency and convenience of tool replacement during electric vehicle assembly.

[0021] Through the above steps, utilizing the spring's reset action, the sliding seat 4 and the unfolding contact button 6 are brought into contact when no screwdriver is placed. The unfolding contact button 6 triggers the first micro motor 107 to rotate, driving the worm gear 106 to rotate. The worm gear 106 rotates, driving the worm wheel 102 to rotate. The worm wheel 102 rotates, driving the grooved disc 103 to rotate. The grooved disc 103 rotates, causing the small slider 104 to slide along the inner side of the grooved disc 103, thereby driving multiple sets of large sliders 105 to slide along the fixed seat 8. The multiple sets of large sliders 105 unfold outward with the center of the fixed seat 8 as the center. The operator places the handle end of the screwdriver against the fixed tube 101 inside the fixed seat 8 and applies a pushing force to the lower end of the inclined slide groove 2, causing the sliding seat 4 to slide obliquely downward along the guide rod 3 into the inclined slide groove 2. The movement causes the sliding seat 4 to contact the locking contact button 7. The locking contact button 7 triggers the first micro motor 107 to drive the worm gear 106 to reverse, causing multiple sets of large sliders 105 to retract inward, fixing the handle end of the screw drill. After the operator releases the handle, the gravity of the screw drill is applied to the sliding seat 4, keeping the sliding seat 4 in contact with the locking contact button 7, thus maintaining the screw drill's fixation. When the operator needs to remove the screw drill, they only need to pull the fixed screw drill with one hand to slide the sliding seat 4 to the unfolding contact button 6 end to remove the screw drill. This device allows for quick placement and removal of the screw drill with only one hand. During operation, one hand can assist in processing the part while the other hand quickly picks up or stores the screw drill, improving work efficiency and convenience.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
