Description

Technical Field

[0001] This invention relates to the field of pressure holding technology, and more particularly to a pressure holding device. Background Technology

[0002] Applying pressure to product components ensures a more stable connection between the glued parts and the product. This is especially important for speakers in 3C products. Firstly, speakers vibrate during operation. Secondly, the edges of 3C products are typically curved. Furthermore, to facilitate sound propagation, the speaker is often positioned at the edge of the product and facing laterally. This results in the speaker being assembled at a certain angle to the product. Therefore, the pressure-holding equipment used for this process places higher demands on the product. How to apply pressure perpendicular to the pressure surface of the component becomes a key challenge. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a pressure-holding device in which the contour groove is inclined and the pressure-holding surface is configured perpendicular to the movement direction of the second drive end. This allows the pressure-holding surface to apply a pressure perpendicular to the pressure-bearing surface of the part, thereby improving the stability of the connection between the part and the product.

[0017] The guide section includes multiple guide rods, which are arranged on both sides of the first drive end. One end of each guide rod is fixedly connected to the bracket, and the other end is fixedly connected to the base plate.

[0018] The driving unit also includes a vertical moving member, which has a plurality of first guide holes, and the plurality of first guide holes are slidably sleeved on the guide rod in a corresponding manner.

[0023] Multiple buffers are installed on the vertical moving part, and the multiple buffers are arranged on both sides of the first drive end and correspond to the two vertical plates;

[0024] During the movement of the vertical moving member toward the contour groove, the guide post passes through the second guide hole and the buffer head of the buffer abuts against the top of the upright plate.

[0025] Furthermore, the supporting part is spaced apart from the bracket, and the bottom surface of the contour groove has a supporting inclined surface, which is inclined towards the bracket;

[0026] The bearing inclined surface has a first preset angle with the moving direction of the second driving end, wherein the first preset angle is consistent with the angle between the pressure surface of the part and the bottom surface of the product.

[0027] Furthermore, the pressure-holding device also includes a base plate;

[0028] The bearing portion includes:

[0029] The support plate has a contoured groove formed on its top, and the bottom surface of the contoured groove has a bearing slope.

[0030] A first pad, comprising a wedge-shaped body, the bottom surface of which is disposed on the bearing plate, the bearing plate being installed above the wedge-shaped body and the bearing inclined surface being parallel to the top surface of the wedge-shaped body.

[0031] Furthermore, the supporting part also includes:

[0040] The second magnetic component of the product is in an attractive state with the first magnetic component, and the outer edge of the product is engaged in the positioning area.

[0041] The pressure-holding device of this invention utilizes a first driver and a second driver to drive the pressure-holding head, and the contour groove is inclined, allowing the pressure-holding surface to move relative to the contour groove in both the vertical and horizontal directions. Thus, on one hand, the inclined contour groove ensures that the product placed within it forms an angle with the horizontal direction, thereby guaranteeing that the pressure-bearing surface is vertical. On the other hand, the pressure-holding surface is configured perpendicular to the movement direction of the second driver and parallel to the movement direction of the first driver. This allows the first driver to feed the pressure-holding surface into the contour groove, ensuring that the pressure-holding surface and the pressure-bearing surface are at the same height and a predetermined distance in the horizontal direction. This facilitates the second driver applying a pressure perpendicular to the pressure-bearing surface, ensuring that the pressure-holding process improves the stability of the connection between the part and the product.

[0075] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0076] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0077] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0078] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0079] Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of the pressure-holding device in different implementations of this embodiment. Figure 1 The pressure-holding device includes a drive unit 1, a support unit 2, a pressure-holding head 3, a bracket 4, and a base plate 5. Product B and part A mounted thereon are disposed in the contour groove 21 of the support unit 2.

[0080] Figure 5 This is a structural schematic diagram of the bearing section 2. The diagram also shows a portion of the bottom area of ​​the pressure-holding head 3. Figure 1 and Figure 5 The pressure-holding device is in a pressure-holding state. That is, the pressure-holding surface 31 is in contact with the pressure-bearing surface A1 of part A.

[0081] Figure 6This is an exploded view of the support unit 2. The top surface of the base plate 5 used to mount the support unit 2 is also shown in the figure with a dashed line. The base plate 5 is in a horizontal position, and the angle α in the figure is the inclination angle of the contour groove 21 relative to the base plate 5.

[0082] Figure 7 This is a partial cross-sectional view of the bearing part 2 and product B. The angle β in the figure represents the angle between the normal to the pressure surface A1 of part A and the bottom surface B1 of product B when part A and product B are in their pre-assembled state. The aforementioned normal refers to a dashed line perpendicular to a plane.

[0083] Figure 8 This is an assembly diagram of part A and product B. In this embodiment, product B can be used to form part of the structure of 3C devices such as electronic watches, electronic bracelets, or mobile phones. The following description uses an electronic watch as an example. Product B in the diagram forms a portion of the electronic watch, which fits against the wrist when the watch is worn. In contrast, part A is a speaker housed within the electronic watch. The side of product B is generally sloped, with two sound holes B4 formed on the slope. These sound holes B4 extend from the aforementioned slope onto the mounting surface B5 of product B (e.g., ...). Figure 7 (As shown). The mounting surface B5 is used to mount part A onto product B. This allows the speaker to be positioned at the edge of product B with the diaphragm facing outwards, facilitating sound propagation from the speaker.

[0084] Figure 7 and Figure 8 The dashed line Ⅲ in the figure represents the center line of sound hole B4. Figure 7 As can be seen, the dashed line Ⅲ is roughly perpendicular to the mounting surface B5. That is, after the speaker is mounted on product B, the speaker diaphragm is roughly perpendicular to the dashed line Ⅲ.

[0085] In some implementations, such as Figure 1-6 As shown, the pressure-holding device in this embodiment includes a pressure-holding head 3, a driving unit 1, and a supporting unit 2. The pressure-holding head 3 includes a pressure-holding surface 31. The driving unit 1 includes a first driver 11 and a second driver 12. The first driver 11 includes a first driving end 13, and the second driver 12 is disposed on the first driving end 13 and includes a second driving end 14. The second driving end 14 is connected to the pressure-holding head 3, and the moving direction of the second driving end 14 is perpendicular to the moving direction of the first driving end 13, and the moving direction of the second driving end 14 is also perpendicular to the pressure-holding surface 31. The supporting unit 2 is provided with a contour groove 21, which is inclined.

[0086] Further reference Figure 7 and Figure 8As shown, the drive unit 1 is configured to drive the pressure-holding surface 31 to extend into the contour groove 21 via the first driver 11. At least a portion of the pressure-holding surface 31 is in a spaced-apart and opposite state to the pressure-receiving surface A1 of part A, and the second driver 12 drives the pressure-holding surface 31 to apply a pressure perpendicular to the pressure-receiving surface A1 of part A. Part A and product B, disposed within the contour groove 21, are in a pre-assembled state.

[0087] like Figure 2 As shown, in this embodiment, the first driver 11 and the second driver 12 are used to realize the vertical movement (direction Y) and horizontal movement (direction X) of the pressure holding head 3, respectively. During the vertical movement, the second driver 12 moves synchronously with the first driving end 13 of the first driver 11. During the horizontal movement, the position of the first driving end 13 of the first driver 11 remains unchanged, and the second driver 12 drives the pressure holding head 3 to move.

[0088] Easy to understand, such as Figure 6-8 As shown, in this embodiment, when part A is installed on product B, the pressure-bearing surface A1 of part A forms a predetermined angle with the bottom surface B1 of product B. This angle varies depending on the internal structure of product B. Taking β as 8 degrees as an example, the inclination angle α of the contour groove 21 in this embodiment is also set to 8 degrees. Therefore, when product B is placed in the contour groove 21 and part A is installed, the pressure-bearing surface A1 can be made to be exactly perpendicular to the base plate 5.

[0089] Specifically, the operator can first place product B into the contour groove 21 (e.g., Figure 2 As shown), and then during the vertical movement of the pressure holding head 3, the pressure holding surface 31 of the pressure holding head 3 aligns with the inner side of product B (as shown). Figure 3 As shown), the pressure-holding surface 31 and the pressure-receiving surface A1 are offset from each other. This is to prevent the pressure-holding head 3 from contacting part A during its downward movement, which would cause part A to disengage from the intended installation position of product B. During horizontal movement (such as...), Figure 4 and Figure 5 As shown), the holding surface 31 gradually approaches and abuts against the pressure-receiving surface A1. When the holding head 3 applies a holding force to part A (as shown), Figure 5 As indicated by the middle arrow, the pressure-holding head 3 will also be subjected to the reverse force of part A. In this embodiment, the driving direction of the first driver 11 and the driving direction of the second driver 12 are configured to be perpendicular to each other. When the second driver 12 is subjected to the reverse force, the first driving end 13 of the first driver 11 can be prevented from being compressed or stretched, which would reduce the pressure applied to the pressure surface A1 or cause the direction to shift.

[0090] In summary, the pressure-holding device of this embodiment uses the first driver 11 and the second driver 12 to drive the pressure-holding head 3 respectively, and the contour groove 21 is inclined so that the pressure-holding surface 31 can move relative to the contour groove 21 in both the height and horizontal directions. Thus, on the one hand, the inclined contour groove 21 allows the product B placed therein to have an angle with the horizontal direction, thereby ensuring that the pressure-receiving surface A1 is in a vertical state. On the other hand, the pressure-holding surface 31 is configured to be perpendicular to the movement direction of the second driving end 14 and parallel to the movement direction of the first driving end 13. This allows the first driver 11 to feed the pressure-holding surface 31 into the inner side of the contour groove 21, and to make the height of the pressure-holding surface 31 the same as that of the pressure-receiving surface A1, with a predetermined distance in the horizontal direction. This facilitates the second driver 12 to apply a pressure perpendicular to the pressure-receiving surface A1, ensuring that the pressure-holding process improves the connection stability between part A and product B.

[0091] Preferably, the first actuator 11 in this embodiment is a double-rod cylinder. The double-rod cylinder is composed of single-rod cylinders. The two drive rods of the double-rod cylinder prevent the first drive end 13 from wobbling during its up-and-down movement and ensure that the pressure-holding head 3 has sufficient stroke. In contrast, the second actuator 12 is a slide cylinder. The slide cylinder has a smaller stroke than the double-rod cylinder, but it offers higher motion precision, ensuring that the magnitude and direction of the pressure applied to the pressure-bearing surface A1 are sufficiently stable.

[0092] Preferably, the pressure-bearing surface A1 is a plane. Correspondingly, the pressure-holding surface 31 is also a plane. Through the mutual contact between the pressure-holding surface 31 and the pressure-bearing surface A1, the pressure-holding force can be evenly applied to the inner side of the product B, preventing the part A from slipping relative to the product B.

[0093] In some implementations, such as Figure 1-5 As shown, the pressure-holding head 3 also includes an extension block 32. The extension block 32 has a first side surface 321, and a pressure-holding surface 31 protrudes from the edge of the first side surface 321 and is close to the contour groove 21. During the movement stroke of the first drive end 13, the extension block 32 corresponds to the bottom of the contour groove 21.

[0094] In this embodiment, the pressure-holding surface 31 is located at the bottom side of the pressure-holding head 3. When the bottom of the insertion block 32 enters the product B, the pressure-holding surface 31 corresponds to the pressure-receiving surface A1. That is, the bottom of the insertion block 32 can maintain a distance from the product B, avoiding collisions with the product B during vertical movement and preventing scratches on the product B during horizontal movement.

[0095] In some implementations, such as Figure 2-3As shown, the pressure-holding device also includes a pressure sensor 33. The pressure sensor 33 includes two mutually opposing detection surfaces 331, each a rectangle with adjacent sides of unequal length. One detection surface 331 is fixedly connected to the side of the extended block 32 away from the pressure-holding surface 31, and the long side of the detection surface 331 is parallel to the direction of movement of the first drive end 13. The other detection surface 331 is connected to the second drive end 14. In this embodiment, the pressure sensor 33 is used to monitor the pressure-holding pressure applied by the second actuator 12 to the pressure-bearing surface A1 to avoid excessive pressure damaging part A.

[0096] Specifically, the pressure sensor 33 in this embodiment is a piezoresistive sensor. A piezoresistive sensor utilizes the piezoresistive effect to change the resistivity of a semiconductor when subjected to stress. When the distance between the two detection surfaces 331 decreases, the resistivity of the piezoresistive sensor changes, thus indirectly detecting the holding pressure applied by the second actuator 12 through the resistivity. The pressure sensor 33 is approximately cuboid. The cross-section along the length of the cuboid is rectangular. Therefore, when the second actuator 12 applies holding pressure to part A through the extension block 32, the connection position of the pressure sensor 33 in this embodiment ensures that after the holding surface 31 enters the product B, the pressure sensor 33 will not contact the product B, avoiding collisions between the pressure sensor 33 and the product B.

[0097] It is easy to understand that the pressure-holding surface 31 and the pressure sensor 33 are located at both ends of the extension block 32. During the application of the pressure-holding force, a torque will be generated on the extension block 32. This makes it difficult to maintain the pressure-holding force in a direction perpendicular to the pressure-bearing surface A1. Therefore, this embodiment utilizes a rectangular detection surface 331 to increase the connection area between the pressure sensor 33 and the extension block 32, thereby reducing or even avoiding changes in the angle between the extension block 32 and the pressure sensor 33 during the application of the pressure-holding force.

[0098] Figure 9 This is a circuit diagram of the pressure-holding device in this embodiment. In some implementations, such as... Figure 9 As shown, the pressure-holding device also includes a controller 82 and a timer 83. The controller 82 is communicatively connected to the timer 83, the pressure sensor 33, the first driver 11, and the second driver 12. In this embodiment, the controller 82 is used to sequentially drive the first driver 11 and the second driver 12 to move. When the second driver 12 applies a pressure-holding force to the pressure-bearing surface A1, the controller 82 monitors the magnitude of the pressure-holding force through the pressure sensor 33.

[0099] Specifically, in this embodiment, the controller 82 is configured to start timer 83 in response to the pressure signal from pressure sensor 33 being greater than a first threshold and to maintain the pressure signal below a second threshold by controlling the first actuator 11. Simultaneously, in response to the timer 83 reaching a third threshold, the controller controls the second drive end 14 of the second actuator 12 to move away from the pressure surface A1 to complete the pressure holding operation. After the pressure holding surface 31 is away from the pressure surface A1, the controller can also control the first actuator 11 to lift the pressure holding head 3 upwards, so that the operator can remove the product B with part A installed.

[0100] Furthermore, the pressure-holding device also includes a display 81 that is communicatively connected to the controller 82. The display 81 is used to display the pressure value of the pressure sensor 33 in real time, so that the operator can monitor the pressure holding.

[0101] In some implementations, such as Figure 1-3 As shown, the pressure-holding device also includes a bracket 4, a base plate 5, and a guide section 6. The bracket 4 and the bearing section 2 are disposed on the base plate 5. The guide section 6 includes multiple guide rods 61, which are arranged on both sides of the first drive end 13. One end of each guide rod 61 is fixedly connected to the bracket 4, and the other end is fixedly connected to the base plate 5. Meanwhile, the drive section 1 also includes a vertical moving member 15, which has multiple first guide holes 151. The multiple first guide holes 151 are correspondingly and slidably fitted onto the guide rods 61. A first driver 11 is mounted on the bracket 4, the first drive end 13 is fixedly connected to the top of the vertical moving member 15, and a second driver 12 is mounted on the bottom of the vertical moving member 15.

[0102] In this embodiment, the cooperation between the vertical moving member 15 and the guide rod 61 increases the motion accuracy of the first driving end 13, ensuring that the pressure-holding surface 31 remains perpendicular to the base plate 5 during its up-and-down movement. Simultaneously, the guide rods 61 located on both sides of the first driving end 13 can bear the reaction force exerted by the pressure-holding surface A1 on the pressure-receiving surface A1 when the pressure-holding surface 31 applies pressure to the pressure-receiving surface A1. Especially when the stroke of the first driving end 13 is long, the pressure-holding head 3 and the cylinder body of the double-rod cylinder are located at opposite ends of the drive rod of the double-rod cylinder. In this configuration, the pressure-holding force applied by the second actuator 12 can cause the drive rod to bend and deform. This embodiment further utilizes the guide rods 61 to reduce the force exerted by the pressure-receiving surface A1 on the drive rod.

[0103] Specifically, the vertical moving member 15 in this embodiment includes a moving plate and a sleeve, with a first guide hole 151 located on the sleeve. The sleeve is fixed to the moving plate and sleeved on the guide rod 61. The first drive end 13 and the second drive unit 12 are respectively fixed at the top and bottom of the moving plate.

[0104] In some implementations, such as Figure 1-3As shown, the guide section 6 also includes a guide post 62 and two upright plates 63. The guide post 62 is mounted on the vertical moving member 15. The two upright plates 63 are disposed on the base plate 5 and located below the vertical moving member 15, and the upright plates 63 have second guide holes 631. Multiple buffers 7 are mounted on the vertical moving member 15, and the multiple buffers 7 are arranged on both sides of the first drive end 13 and correspond to the two upright plates 63. During the movement of the vertical moving member 15 toward the contour groove 21, the guide post 62 passes through the second guide hole 631 and the buffer head of the buffer 7 abuts against the top of the upright plate 63.

[0105] Specifically, when the first actuator 11 drives the pressure-holding surface 31 to move to the position corresponding to the pressure-receiving surface A1, the second actuator 12 and the pressure-holding head 3 are located between the two upright plates 63, and the vertical moving member 15 is spaced apart from the two upright plates 63. In this embodiment, the cooperation between the second guide hole 631 and the guide post 62 further guides the movement of the insertion block 32 before it enters the product B, ensuring the relative positional relationship between the pressure-holding surface 31 and the pressure-receiving surface A1. At the same time, the contact between the buffer head and the upright plate 63 can slow down the speed at which the insertion block 32 enters the product B, preventing the first actuator 11 from moving too fast and causing the insertion block 32 to collide with the product B.

[0106] Preferably, the buffer 7 in this embodiment is a hydraulic buffer. The hydraulic buffer includes a hydraulic cylinder, a piston, a piston rod, a hydraulic cylinder head, a buffer spring, and sealing elements. In this embodiment, the buffer head of the buffer 7 is located at the extended end of the piston rod. Before the insert block 32 enters the inner side of product B, it contacts the top of the upright plate 63.

[0107] In some implementations, such as Figure 1-4 As shown, the supporting part 2 and the bracket 4 are spaced apart, and the bottom surface B1 of the contour groove 21 has a supporting inclined surface 211, which is inclined towards the bracket 4. That is, as Figure 2 As shown, the side of the contour groove 21 furthest from the bracket 4 is higher than the side closest to the bracket 4. The bearing inclined surface 211 and the moving direction of the second driving end 14 have a first preset angle. This first preset angle coincides with the angle between the pressure surface A1 of part A and the bottom surface B1 of product B. That is... Figure 6 and Figure 7 In the equation, angles α and β are of the same magnitude.

[0108] Further reference Figure 8 As shown, when product B is placed into the contour groove 21, the bottom surface B1 of product B abuts against the bearing inclined surface 211 of the contour groove 21. When part A is installed in product B, the pressure-bearing surface A1 in the contour groove 21 is parallel to the movement direction of the first drive end 13, so that the pressure-holding surface 31 can apply a uniform pressure to the pressure-bearing surface A1 and the pressure-holding surface 31 will not easily move in the height direction.

[0109] In some implementations, such as Figure 1-6 As shown, the pressure holding device also includes a base plate 5. The support part 2 includes a support plate 22 and a first pad 23. A contour groove 21 is formed on the top of the support plate 22, and the bottom surface B1 of the contour groove 21 has a bearing inclined surface 211. The first pad 23 includes a wedge 231, the bottom surface B1 of the wedge 231 is disposed on the support plate 22, the support plate 22 is installed above the wedge 231, and the bearing inclined surface 211 is parallel to the top surface of the wedge 231. In this embodiment, the wedge 231 allows the contour groove 21 to be set at an angle, simplifying the support plate 22 and the overall structure. When the operator needs to adjust the tilt angle of the contour groove 21, the first pad 23 can be directly replaced. This reduces the manufacturing cost of the pressure holding device and avoids the situation where the contour groove 21 needs to be replaced due to an unsuitable setting angle. It also further enables the pressure holding device to perform pressure holding for different types of products B, improving the flexibility of the pressure holding device.

[0110] Specifically, the bottom surface B1 of the first pad 23 is flat, and one side of the top surface is higher than the other. Therefore, in this embodiment, the inclination angle of the contour groove 21 can be adjusted by changing the slope of the top surface.

[0111] In some implementations, such as Figure 1-6 As shown, the support portion 2 also includes a second pad 24, a cover plate 25, and a limiting member 26. The second pad 24 is disposed on top of the first pad 23, and the cover plate 25 is rotatably connected to the second pad 24 and has a contour hole 251. Correspondingly, the limiting member 26 is disposed on the second pad 24. The support plate 22 is detachably disposed on the second pad 24. When the cover plate 25 presses against the support plate 22, the cover plate 25 is constrained by the limiting member 26, so that the cover plate 25 is stably pressed against the support plate 22. At the same time, the contour hole 251 corresponds to the contour groove 21. In this embodiment, the cover plate 25 can prevent the product B from moving around in the contour groove 21, and the contour hole 251 can avoid the pressure holding head 3 during its movement into the contour groove 21.

[0112] As is easily understood, in this embodiment, the support plate 22, the second pad 24, the cover plate 25, and the limiting member 26 together form a positioning assembly. That is, the operator can first use this positioning assembly to position product B. After positioning is completed, the positioning assembly and product B are then placed together on the first pad 23, thereby simplifying the operator's clamping operation of product B.

[0113] Furthermore, the support plate 22 includes a receiving member 225 and a support block 224. The center of the receiving member 225 is provided with a first receiving groove 2251. The aforementioned contour groove 21 is opened on the top of the support block 224, and the support block 224 is engaged in the first receiving groove 2251.

[0114] It is easy to understand that when the shape of product B remains unchanged but the angle between the pressure surface A1 and the bottom surface B1 changes, this embodiment can change the placement position of part A by replacing the first pad 23 (changing the tilt angle). When the shape of product B changes but the angle between the pressure surface A1 and the bottom surface B1 remains unchanged, this embodiment can change the shape of the contour groove 21 by replacing the bearing block 224.

[0115] In other words, this embodiment utilizes the first pad 23 to adapt to pressure surfaces A1 at different angles, and the bearing block 224 to adapt to different shapes of product B. This maximizes the adaptability of the pressure-holding equipment to different pressure-holding workpieces and reduces pressure-holding costs.

[0116] In some implementations, such as Figure 6 and Figure 8 As shown, the support part 2 includes a plurality of first magnetic elements 27. A plurality of mounting holes 212 are formed at the bottom of the contoured groove 21, and the plurality of first magnetic elements 27 are correspondingly disposed in the mounting holes 212. Product B is disposed within the contoured groove 21, and the plurality of second magnetic elements B2 of product B are attracted to the plurality of first magnetic elements 27 in a corresponding manner.

[0117] It is easy to understand that a plurality of second magnetic elements B2 are provided inside the product B in this embodiment. These second magnetic elements B2 are pre-installed inside the product B. When the product B is connected to the charging dock, the aforementioned second magnetic elements B2 can attract the product B to the charging dock, so that the charging dock can abut against the charging contacts of the product B (e.g., ...). Figure 8 (As shown in the middle region II).

[0118] In this embodiment, the second magnetic component B2 is used to attract the product B to the first magnetic component 27 at the bottom of the contour groove 21, so as to ensure that the product B will not easily move in the contour groove 21, and at the same time, it can further ensure the positional accuracy between the product B and the contour groove 21.

[0119] Specifically, such as Figure 6 As shown, a positioning protrusion is also provided between the two mounting holes 212. When product B is set in the contour groove 21, the positioning protrusion will pass through the recess where the charging contacts are set on product B (e.g., Figure 8 (As shown in area II). This is to further improve the positional accuracy between product B and the contour groove 21, and to ensure the installation orientation of product B within the contour groove 21.

[0120] In some implementations, such as Figure 4 , Figure 6 and Figure 8As shown, the supporting part 2 includes a supporting plate 22. A contoured groove 21 is formed on the top of the supporting plate 22. The supporting plate 22 includes multiple first locking platforms 221, which protrude from the top of the supporting plate 22. The first locking platforms 221 are located on the top of the sidewall of the contoured groove 21. Multiple mounting holes 212 are provided near the side of the contoured groove 21, and a positioning area 223 is formed between two adjacent first locking platforms 221. The second magnetic component B2 of product B is in an attracted state with the first magnetic component 27, and the outer flange B3 of product B is engaged within the positioning area 223 (e.g., ...). Figure 8 (As shown in region I). This ensures the circumferential positioning accuracy of product B in the contour groove 21.

[0121] Specifically, such as Figure 6 As shown, there are two positioning areas 223 in the figure, located on both sides of the contour groove 21. When the operator places product B into the contour groove 21, it may be installed upside down. By placing the first magnetic component 27 on the side closer to the contour groove 21, when the operator installs product B in reverse, the first magnetic component 27 and the second magnetic component B2 cannot be attracted to each other, thus reminding the operator to turn product B in the opposite direction in time.

[0122] Preferably, such as Figure 6 As shown, a second locking platform 222 protrudes from the top of the support plate 22, and this second locking platform 222 is located between two adjacent first locking platforms 221. That is, the two first locking platforms 221 and the second locking platform 222 surround and form the aforementioned positioning area 223. Thus, the two first locking platforms 221 can abut against both sides of the outward flange B3, and the second locking platform 222 can abut against the end of the outward extension direction of the outward flange B3, that is, the side of the outward flange B3 away from the center of the contour groove 21. Thus, the positional accuracy between the product B and the contour groove 21 can be maximized.

[0123] Optionally, the sidewall of the contour groove 21 is a cylindrical surface and perpendicular to the bearing inclined surface 211. When product B is placed in the contour groove 21, as... Figure 4 As shown in region IV, the inclined surface of product B has a gap with the contour groove 21. Meanwhile, as... Figure 6 As shown, the cover plate 25 in this embodiment includes a cover body 253 and a washer 252. A second receiving groove 2531 for accommodating the washer 252 is formed on the side of the cover body 253 facing the contour groove 21. The washer 252 is made of urethane elastomer. Urethane elastomer, also known as polyurethane elastomer, is a material with good strength and low compression deformation. The contour hole 251 described above penetrates both the cover body 253 and the washer 252. Figure 4 and Figure 6As shown, in this embodiment, multiple arc-shaped edges 2521 are protruding from the side of the washer 252 facing the contour groove 21. These arc-shaped edges 2521 are located at the edge of the contour hole 251 and are spaced apart to avoid the first retaining platform 221. Each arc-shaped edge 2521 presses against the top of the outer flange B3 of product B. The bottom surface B1 and the outer flange B3 of product B are relatively flat compared to the inclined surface of product B. Therefore, in this embodiment, product B, through the cooperation of its bottom surface B1 and outer flange B3 with the bearing inclined surface 211, the first retaining platform 221, the second retaining platform 222, and the arc-shaped edges 2521, achieves accurate positioning of product B by the bearing part 2.

For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
