Description

Technical Field

[0001] This utility model relates to the field of pressure holding equipment technology, specifically to a pressure holding device and system for vehicle-mounted wireless charging products. Background Technology

[0002] During the production of automotive CWC (wireless charging) products, a pressure holding operation is required to ensure that different functional modules are firmly stacked together, facilitating subsequent assembly.

[0003] For example, patent application number 202320372541.1 discloses a pressure-holding device for in-vehicle wireless charging products. This utility model relates to a pressure-holding device for in-vehicle wireless charging products, which includes a conveying mechanism and a pressing mechanism. The conveying mechanism moves the product to a designated position by the pressing mechanism, where the pressing mechanism applies pressure. The pressing mechanism is equipped with two cylinders. The first cylinder is mounted on a first mounting plate, which is connected to a fourth mounting plate with a pressure-holding cavity fixed below it via a guide shaft and bearings, allowing the first cylinder to drive the pressure-holding cavity downwards. The second cylinder is mounted on a second mounting plate, which is connected to a third mounting plate for upward operation via a guide shaft and bearings, allowing the second cylinder to drive the third mounting plate upwards and press the pressure-holding top plate. The pressure-holding top plate and the pressure-holding cavity cooperate to achieve bidirectional pressing of the product to be processed placed on the pressure-holding top plate. The device described in this utility model is specifically designed for in-vehicle wireless charging products. It achieves bidirectional pressing from top to bottom and has multiple pressure-holding acupoints, resulting in good pressure holding effect and high working efficiency. However, when pressing the wireless charging product, this in-vehicle wireless charging product pressure-holding device uses simultaneous pressing from top to bottom. This device cannot control the instantaneous pressure during pressing, and the wireless charging product may be damaged due to excessive instantaneous pressure during clamping. In addition, the production cost is relatively high.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a pressure-maintaining device for vehicle-mounted wireless charging products. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-2 As shown, a pressure-holding device for a vehicle-mounted wireless charging product includes a pressure-holding device body 1. A cylinder 2 is installed at the upper end of the pressure-holding device body 1, and a sliding pressure rod 201 is provided at the front end of the cylinder 2.

The advantage of this arrangement is that, by setting the buffer spring 203, the instantaneous pressure of the pressure plate 4 on the wireless charging product can be reduced when the cylinder 2 pushes the sliding pressure rod 201 forward to press down on the wireless charging product, so as to ensure the uniformity of the downward pressure, improve the quality of the wireless charging product, and at the same time reduce the use of the cylinder 2 and reduce the production cost of the pressure holding equipment.

[0026] Furthermore, a limiting slide rod 204 is slidably mounted on the front end surface of the sliding pressure rod 201, and the upper surface of the limiting slide rod 204 is provided with a threaded groove. The advantage of this setting is that the downward pressing direction of the compression spring 307 can be restricted by the setting of the limiting slide rod 204, thereby improving the service life of the compression spring 307.

[0027] like Figures 3-4 As shown, a placement plate 3 is slidably installed on the lower inner surface of the pressure holding device body 1, and a limit frame 301 is provided at the upper end of the placement plate 3. The advantage of this setting is that the position of the placement plate 3 can be restricted by the setting of the limit frame 301, so as to prevent it from being pushed out of the lower inner surface of the pressure holding device body 1.

[0028] Furthermore, a threaded rotating rod 305 is rotatably mounted on the middle of the lower end surface of the placement plate 3, and a sliding support plate 304 is spirally mounted on the surface of the threaded rotating rod 305. The advantage of this setting is that the pressure of the compression spring 307 can be adjusted by the threaded rotating rod 305, so that when the downward pressure of the pressure plate 4 is greater than the set value of the compression spring 307, the wireless charging product placed on the surface can be protected by the compression buffer placement plate 3.

[0029] Furthermore, a connecting plate 302 is provided on the lower surface of the pressure holding device body 1, and a sliding groove 303 is provided on the inner wall surface of the connecting plate 302. The sliding support plate 304 and the connecting plate 302 are slidably connected. The advantage of this setting is that, through the setting of the connecting plate 302, the sliding support plate 304 can be supported while allowing it to slide along the sliding groove 303 opened on the inner wall.

[0030] Furthermore, limit slide rods 306 are installed on both sides of the lower surface of the placement plate 3, and compression springs 307 are installed on the surface of the limit slide rods 306. The advantage of this setting is that the compression direction of the compression springs 307 can be controlled by setting the limit slide rods 306.

[0031] Furthermore, a rotating connecting sleeve 401 is spirally installed on the upper surface of the limiting slide bar 204, and a positioning block 402 is inserted and connected to the front end surface of the limiting slide bar 204. The advantage of this setting is that the positioning block 402 facilitates the positioning connection of the pressure plate 4.

[0032] Furthermore, a support rod 403 is provided at the rear end of the positioning plug 402, and the support rod 403 is connected to the rotating connecting sleeve 401 by a screw. A pressure plate 4 is provided at the lower end of the support rod 403. The advantage of this setting is that, by setting the rotating connecting sleeve 401, different shaped pressure plates 4 can be replaced according to the different shapes of wireless charging products, thereby speeding up the replacement and installation of pressure plates 4.

[0033] On the other hand, the vehicle-mounted wireless charging product pressure-maintaining system of this utility model includes any of the above-mentioned vehicle-mounted wireless charging product pressure-maintaining devices.

[0034] Working Principle: When using this vehicle-mounted wireless charging product pressure-holding device, firstly, based on the clamping force that the wireless charging product can withstand, the sliding support plate 304 is slid along the connecting plate 302 by rotating the threaded rotating rod 305 to adjust the pressure. After the pressure is adjusted by pressing the compression spring 307, the wireless charging product is placed on the surface of the placement plate 3. Then, the cylinder 2 is activated to push the sliding pressure rod 201 forward until the pressure plate 4 contacts the surface of the wireless charging product. Then, the connecting ring 202 presses the buffer spring 203 to buffer the instantaneous pressure and maintain the pressure on the wireless charging product. When the pressure plate 4 needs to be replaced, the positioning insert 402 at the upper end of the support rod 403 of the pressure plate 4 is inserted into the front end of the limiting slide rod 204. Finally, the rotating connecting sleeve 401 on the surface of the limiting slide rod 204 is screwed into the surface of the support rod 403 to complete the replacement. This is the working principle of the vehicle-mounted wireless charging product pressure-holding device.
