Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, specifically to a pin press-fitting device. Background Technology

[0002] In numerous fields such as machinery manufacturing, electronic equipment, and the automotive industry, pins are widely used as common connecting and positioning elements in the assembly process of various products. Their function is to reliably connect different parts together, ensuring the structural stability and assembly accuracy of the product. With the continuous improvement of industrial automation and the stringent requirements for product quality, the efficiency and precision requirements for pin press-fitting processes are also increasing.

[0003] In existing technologies, traditional pin pressing methods rely primarily on operators using simple tools, resulting in slow manual operation. Each pin requires manual hammering or pressing, which cannot meet the demands of large-scale production, and the assembly accuracy and quality stability of the pins are poor. Alternatively, existing pin pressing devices can only perform pressing operations on one side of the housing. For housings with complex structures requiring pin pressing from different directions, multiple adjustments to the workpiece position or the use of multiple machines are necessary, increasing the complexity and cost of the production process and impacting production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a pin pressing device to solve the problems of low automation and poor pressing quality in pin pressing.

[0015] In one embodiment, the pin pressing device further includes a first pressing assembly, which includes a fifth driving member and a first pressing plate. The fifth driving member is disposed on the support frame and connected to the first pressing plate. When the second driving member drives the first pressing member to press the pin into the housing, the fifth driving member drives the first pressing plate to press downward onto the housing.

[0016] In one embodiment, the pin pressing device further includes a second pressing assembly, which includes a sixth driving member and a second pressing plate. The sixth driving member is disposed on the support frame and connected to the second pressing plate. When the third driving member drives the second pressing member to press the pin into the housing, the sixth driving member drives the second pressing plate to press downward onto the top surface of the housing.

[0017] In one embodiment, the second pressing assembly further includes a second mounting base, a seventh driving member, a first pressing rod, and a second pressing rod. The second mounting base is connected to the support frame, the seventh driving member is disposed on the second mounting base, one end of the first pressing rod is connected to the output end of the seventh driving member, and one end of the second pressing rod is connected to the second pressing plate.

[0018] There are two second pressing mechanisms.

[0022] In one embodiment, two second pressing mechanisms are provided, and the feeding mechanism further includes a second vibratory plate, a second feed channel, and a third feed channel. The second feed channel is used to receive the pins transported by the second vibratory plate and convey them to the second pressing component of one of the second pressing mechanisms. The third feed channel is used to receive the pins transported by the second vibratory plate and convey them to the second pressing component of the other second pressing mechanism.

[0023] Compared with the prior art, this application has at least the following beneficial effects:

[0024] 1. In this application, the displacement mechanism enables the sliding component to quickly switch between the first and second stations. The first and second pressing mechanisms perform pressing operations at different stations, realizing parallel operation of multiple stations, reducing workpiece clamping and waiting time, and greatly shortening the pressing cycle of a single housing, thereby improving overall production efficiency. Furthermore, the feeding mechanism can automatically and continuously deliver pins to the first and second pressing components without manual feeding, further improving the continuity and automation of the production process.

[0025] 2. In this application, the second pressing mechanism and the second pressing mechanism press from both sides of the sliding member respectively.

Detailed Implementation

[0043] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0044] refer to Figures 1-5 This application provides a pin pressing device for pressing a pin 200 onto a housing 100. The pin pressing device includes a displacement mechanism 300, a first pressing mechanism 400, a second pressing mechanism 500, and a feeding assembly.

[0045] The displacement mechanism 300 includes a first driving member 310 and a slidable sliding member 320. The sliding member 320 is used to place the housing 100 and has a first station and a second station. The first driving member 310 is connected to the sliding member 320 and drives the sliding member 320 to switch between the first station and the second station. The first driving member 310 is the power source for the sliding of the sliding member 320, and can be a cylinder, electric push rod, or servo motor, providing stable and controllable power output. The sliding member 320 is a platform for supporting the housing 100, and its surface is designed with a positioning structure adapted to the housing 100 to ensure the stability of the housing 100 during placement and pressing. The first driving member 310 is connected to the sliding member 320. Through the forward and reverse movement of the first driving member 310, the sliding member 320 is driven to switch between the first station and the second station, allowing the housing 100 to undergo different pressing operations in different positions, providing flexible position adjustment for subsequent pressing processes.

[0046] The first pressing mechanism 400 is located on one side of the sliding member 320. The first pressing mechanism 400 includes a second driving member 410 and a first pressing member 420. The second driving member 410 is connected to the first pressing member 420 and drives the first pressing member 420 to press the pin 200 into the housing 100 when the sliding member 320 is in the first position. The second driving member 410 can also be a cylinder, hydraulic cylinder, or electric cylinder, etc., and its function is to provide the pressure required for pressing the first pressing member 420. The first pressing member 420 is the component that directly contacts the pin 200 and applies pressure; its shape and size are designed according to the specifications of the pin 200 and the pressing requirements. When the sliding member 320 is in the first position, the second driving member 410 is activated, driving the first pressing member 420 to move towards the housing 100, accurately pressing the pin 200 placed on the first pressing member 420 into the corresponding hole on one side of the housing 100.

[0047] The second pressing mechanism 500 is located on the other side of the sliding member 320. The pin 200 pressing mechanism includes a third driving member 510 and a second pressing member 520. The third driving member 510 is connected to the second pressing member 520 and drives the second pressing member 520 through the sliding member 320 to press the pin 200 into the housing 100 when the sliding member 320 is in the second working position. The function and type of the third driving member 510 are similar to those of the second driving member 410, providing power to the second pressing member 520. When the sliding member 320 switches to the second working position, the third driving member 510 drives the second pressing member 520 through the sliding member 320 (a clearance structure is provided at the corresponding position on the sliding member 320) to press the pin 200 placed on the second pressing member 520 into the housing 100, thereby realizing the pressing of multiple pins 200 on the housing 100.

[0048] The feeding mechanism 600 is used to convey the pins 200 to the first pressing component 420 and the second pressing component 520 respectively. The feeding mechanism 600 operates continuously, conveying the pins 200 from the storage position to the corresponding positions of the first pressing component 420 and the second pressing component 520 in sequence, providing a stable supply of pins 200 for the pressing process, and ensuring the continuity and automation of the entire pressing process.

[0049] In this application, the displacement mechanism 300 enables the sliding member 320 to quickly switch between the first and second workstations. The first pressing mechanism 400 and the second pressing mechanism 500 perform pressing operations at different workstations, realizing parallel operation of multiple workstations, reducing workpiece clamping and waiting time, and greatly shortening the pressing cycle of a single housing 100, thereby improving overall production efficiency. Furthermore, the feeding mechanism 600 can automatically and continuously transport the pins 200 to the first pressing member 420 and the second pressing member 520 without manual feeding, further improving the continuity and automation of the production process.

[0050] The second pressing mechanism 500 and the second pressing mechanism 500 press from both sides of the sliding member 320 respectively. For some complex housings 100 that need to ensure the pressing quality of the pins 200 from different directions, the double-sided pressing can complement and calibrate each other, further improving the accuracy and stability of the pin pressing and ensuring that the product quality meets high standards.

[0051] Meanwhile, the first pressing mechanism 400 and the second pressing mechanism 500 can work independently or in concert. They can flexibly adjust the pressing method and sequence according to different pressing process requirements, such as pressing a single pin 200 or pressing multiple pins 200 simultaneously, to meet diverse production needs.

[0052] refer to Figures 4-7The sliding member 320 is provided with a support assembly 330, which includes a first mounting base 331, a support member 332, and a fourth driving member 333. The fourth driving member 333 is connected to the first mounting base 331, which has a mounting groove 331a. The output end of the fourth driving member 333 is connected to the support member 332 and drives the support member 332 to extend and retract within the mounting groove 331a. When the second driving member 410 drives the first pressing member 420 to press the pin 200 into the housing 100, the end of the support member 332 away from the fourth driving member 333 supports the housing 100 upwards. The support assembly 330 is a structure used to dynamically support the housing 100 during the pressing process. Specifically, a hydraulic cylinder or an electric push rod can be used as the fourth driving member 333. The fourth driving member 333 controls the translation of the support member 332 through its extension and retraction movement. The mounting groove 331a is a guide structure provided on the first mounting base 331 to limit the movement trajectory of the support member 332. The support member 332 is a supporting component that directly contacts the housing 100, and can be implemented by using a metal top rod or a nylon block with a bevel.

[0053] Specifically, when the slider 320 moves to the first station, the fourth drive 333 activates and pushes the support 332 to extend along the mounting groove 331a, so that one end of the support 332 abuts against the bottom edge of the housing 100. At this time, the first pressing mechanism 400 starts working, and the second drive 410 drives the first pressing member 420 to apply a vertically downward pressing force to the housing 100. The support 332, through rigid support, counteracts this pressure, preventing the housing 100 from shifting or deforming during the pressing process. After pressing is completed, the fourth drive 333 drives the support 332 to retract into the mounting groove 331a, providing space for the slider 320 to switch to the second station.

[0054] This application uses a retractable support member 332 to provide a support force in real time that is opposite to the direction of the pressing force during the pressing process, forming a two-way force balance to ensure the pressing accuracy of the pin 200.

[0055] The pin pressing device also includes a frame 700, which includes a worktable 710 and a support frame 720 connected to the worktable 710. The worktable 710 is provided with a slide rail 711. The sliding member 320 includes a first side 321 and a second side 322 arranged opposite to each other. The first side 321 is used to support the housing 100. The second side 322 is provided with a slide block 323, which is slidably connected to the slide rail 711. The first pressing mechanism 400 is provided on the support frame 720. The second pressing mechanism 500 is provided on the worktable 710. The sliding member 320 is provided with a through hole 324 that passes through the first side 321 and the second side 322. The second pressing member 520 protrudes from the first side 321 through the through hole 324.

[0056] The frame 700 is a framework structure that supports the main body of the pressing device. Specifically, it can be formed by welding or bolting metal sheets to create a worktable 710 and a support frame 720. The worktable 710 provides a horizontal mounting surface, and the support frame 720 provides vertical mounting space. The slide rail 711 is a linear guide component that guides the movement of the sliding member 320. The slide block 323 cooperates with the slide rail 711 to achieve smooth displacement of the sliding member 320. The through hole 324 is a hole structure that penetrates both sides of the sliding member 320, allowing the second pressing member 520 to pass through the sliding member 320 to perform pressing operations on the housing 100.

[0057] Specifically, when the housing 100 is placed on the first side 321 of the slider 320, the slide block 323 moves along the slide rail 711, causing the slider 320 to switch between the first and second positions. The first pressing mechanism 400 is mounted on the support frame 720 and can perform unilateral pressing on the housing 100 at the first position; the second pressing mechanism 500 is mounted on the worktable 710, and when the slider 320 moves to the second position, the second pressing component 520 passes through the through hole 324 to perform reverse pressing on the housing 100 from the other side. The position of the through hole 324 matches the movement path of the second pressing component 520, ensuring that the pin 200 accurately passes through the housing 100 during the pressing process.

[0058] This application achieves automatic switching of the sliding part 320 through the structure of slide rail 711 and through hole 324, and completes bidirectional pressing operation with the first pressing mechanism 400 and the second pressing mechanism 500 on both sides. The assembly of pins 200 at different positions of housing 100 can be achieved without manual intervention, thereby improving the automation level of the pressing process.

[0059] refer to Figure 8 , Figure 9 and Figure 10 The pin pressing device also includes a first pressing assembly 800, which includes a fifth driving member 810 and a first pressing plate 820. The fifth driving member 810 is mounted on the support frame 720 and connected to the first pressing plate 820. When the second driving member 410 drives the first pressing member 420 to press the pin 200 into the housing 100, the fifth driving member 810 drives the first pressing plate 820 to press downwards onto the housing 100. The fifth driving member 810 is a power element capable of providing linear motion output, specifically a cylinder or hydraulic cylinder, used to drive the first pressing plate 820 to move vertically. The first pressing plate 820 is a rigid component with a flat contact surface, specifically a metal disc structure, used to apply downward pressure to the housing 100 during the pressing process to prevent displacement of the housing 100.

[0060] Specifically, when the sliding member 320 moves to the first station, the first pressing mechanism 400 is activated, and the second driving member 410 pushes the first pressing member 420 to press the pin 200 into the housing 100. During this process, the fifth driving member 810 simultaneously drives the first pressure plate 820 to move downward, so that the bottom surface of the first pressure plate 820 contacts the top surface of the housing 100 and applies pressure. Through the pressing action of the first pressure plate 820 on the housing 100, the housing 100 is stably fixed on the sliding member 320, avoiding the housing 100 from shifting or vibrating due to the pressing impact force, thereby ensuring the accurate pressing position of the pin 200.

[0061] This application adds a first pressing component 800 to apply pressing force synchronously during the pressing action, effectively counteracting the reaction force generated during the pressing process, significantly improving the positioning stability of the housing 100, suppressing the displacement problem caused by uneven force on the housing 100 during single-sided pressing, avoiding the pin 200 pressing position deviation caused by the offset of the housing 100, and improving the consistency and yield of the pressing process.

[0062] The pin pressing device also includes a second pressing assembly 900, which includes a sixth driving member 910 and a second pressing plate 920. The sixth driving member 910 is mounted on the support frame 720 and connected to the second pressing plate 920. When the third driving member 510 drives the second pressing member 520 to press the pin 200 into the housing 100, the sixth driving member 910 drives the second pressing plate 920 downward to press against the top surface of the housing 100. The sixth driving member 910 is a power element capable of providing linear thrust, specifically a cylinder or hydraulic cylinder, and its function is to control the position of the second pressing plate 920 by outputting axial movement. The second pressing plate 920 is a pressing component with a planar structure, specifically made of sheet metal, and its function is to apply vertical pressure by contacting the top surface of the housing 100 to limit the displacement of the housing 100.

[0063] Specifically, when the third driving member 510 pushes the second pressing member 520 to press the pin 200 into the housing 100, the sixth driving member 910 simultaneously starts and drives the second pressing plate 920 to move downward, so that the bottom surface of the second pressing plate 920 contacts the top surface of the housing 100. At this time, the second pressing plate 920 continuously applies vertical pressure to fix the housing 100 onto the sliding member 320, preventing the housing 100 from shifting or vibrating due to force during the pressing process. This pressing action works in conjunction with the pressing force of the second pressing member 520 to ensure that the pin 200 is accurately embedded into the housing 100 along a predetermined trajectory.

[0064] This application adds a second pressing component 900 to apply an active pressing force to the top of the housing 100 during the pressing process of the second pressing mechanism 500, forming a two-way constraint, effectively suppressing the displacement and deformation of the housing 100, and avoiding the decrease in assembly accuracy caused by the displacement of the housing 100.

[0065] Furthermore, the second pressing assembly 900 also includes a second mounting base 930, a seventh driving member 940, a first pressing rod 950, and a second pressing rod 960. The second mounting base 930 is connected to the support frame 720. The seventh driving member 940 is disposed on the second mounting base 930. One end of the first pressing rod 950 is connected to the output end of the seventh driving member 940, and one end of the second pressing rod 960 is connected to the second pressing plate 920. There are two second pressing mechanisms 500. When the third driving member 510 of the two second pressing mechanisms 500 drives the second pressing member 520 to press the pin 200 into the housing 100, the other end of the first pressing rod 950 and the other end of the second pressing rod 960 press downward onto the housing 100.

[0066] The second mounting base 930 is a structural component used to fix and support the seventh driving component 940. It can be formed from sheet metal and connected to the support frame 720 via bolts, thus stabilizing the driving component. The seventh driving component 940 is a device that provides linear motion power, specifically a cylinder or electric actuator, used to control the lifting and lowering of the first pressure rod 950. The first pressure rod 950 and the second pressure rod 960 are rigid rods that transmit pressure, and their ends can be fitted with buffer pads to reduce impact on the housing 100. The two second pressing mechanisms 500 can simultaneously perform pin 200 pressing operations on different positions of the housing 100.

[0067] Specifically, when the two second pressing mechanisms 500 simultaneously perform pressing actions, the seventh driving member 940 drives the first pressing rod 950 to move downward, and the second pressing rod 960 is driven by the second pressing plate 920 to press down synchronously. The ends of the first pressing rod 950 and the second pressing rod 960 act on the surface of the housing 100 respectively, forming a multi-point holding force to counteract the lateral force generated during the pressing process of the two second pressing mechanisms 500.

[0068] This application generates symmetrical holding force during the double-sided pressing process, effectively suppressing displacement of the housing 100. Simultaneously, the coordinated action of the two second pressing mechanisms 500 and the second holding assembly 900 avoids multiple positioning operations, improving processing efficiency.

[0069] refer to Figure 2 , Figure 3 and Figures 10-12The first pressing mechanism 400 also includes a guide sleeve 430, which is connected to the support frame 720 and sleeved on the first pressing component 420. The guide sleeve 430 has a connected first channel 431 and a second channel 432. The first channel 431 is connected to the feeding mechanism 600, and one end of the first pressing component 420 can pass through the first channel 431. The guide sleeve 430 is a sleeve structure with a guiding function, and its inner wall is clearance-fitted with the outer surface of the first pressing component 420 to constrain the movement trajectory of the first pressing component 420. The first channel 431 is a material conveying path penetrating the side wall of the guide sleeve 430, and can specifically adopt an inclined tubular structure to receive the pins 200 conveyed by the feeding mechanism 600. The second channel 432 is a guide cavity extending axially along the guide sleeve 430 to accommodate the reciprocating motion of the first pressing component 420.

[0070] Specifically, when the feeding mechanism 600 delivers the pin 200 to the inlet of the first channel 431, the pin 200 slides into the guide sleeve 430 along the first channel 431 under the action of gravity or pushing force. At this time, the first pressing component 420 moves axially along the second channel 432 under the drive of the second driving component 410. Its front end extends from the outlet of the first channel 431 and contacts the pin 200, clamping the pin 200 and continuing to advance forward, finally pressing the pin 200 into the preset hole of the housing 100. The guide sleeve 430, through the connection design of the first channel 431 and the second channel 432, makes the pin 200 delivery path and the pressing motion trajectory spatially intersect, ensuring that the pin 200 can accurately enter the pressing position.

[0071] This application utilizes the dual-channel design of the guide sleeve 430 to create a spatial constraint relationship between the pin 200 conveying path and the pressing motion, eliminating the need for manual adjustment of the pin 200 position. The guide sleeve 430 structure ensures that the pin 200 remains under control during the pressing process, preventing assembly deviations caused by vibration or external force interference.

[0072] The first pressing mechanism 400 also includes an elastic element 440, which is sleeved on the first pressing member 420. One end of the elastic element 440 abuts against the output end of the second driving member 410, and the other end abuts against the inner wall of the guide sleeve 430. The elastic element 440 is a mechanical component capable of absorbing impact force through elastic deformation. Specifically, it can be implemented using a coil spring, disc spring, or rubber buffer pad. Its function is to buffer the rigid contact between the first pressing member 420 and the pin 200, preventing the housing 100 from shifting or being damaged due to instantaneous impact force during the pressing process.

[0073] Specifically, when the second driving member 410 pushes the first pressing member 420 to perform the pressing action, the elastic member 440 is compressed and stores energy. At this time, the pressing member moves linearly along the inner wall of the guide sleeve 430, pressing the pin 200 into the housing 100. When the pressing is completed and the driving member retracts, the elastic member 440 releases the stored energy, allowing the pressing member to quickly reset. During this process, the elastic member 440 not only buffers the rigid collision between the first pressing member 420 and the pin 200, but also uses elastic force to allow the first pressing member 420 to reset above the connection position between the first channel 431 and the second channel 432, avoiding interference with the pin 200 input into the first channel 431.

[0074] The feeding mechanism 600 includes a first vibratory feeder 610, a first feed channel 620, and an eighth driving member 630. The first feed channel 620 is connected between the first vibratory feeder 610 and the first channel 431. The eighth driving member 630 is connected to the first feed channel 620 and drives the pins 200 to move towards the first channel 431. The first vibratory feeder 610 is a vibratory feeding device for automatically sorting and conveying the pins 200. Specifically, it can use electromagnetic vibration to drive the internal track to generate directional vibration, causing the pins 200 to be arranged orderly along the track and conveyed to the entrance of the first feed channel 620, thus solving the problem of low efficiency in manual feeding. The first feed channel 620 is a guide channel connecting the first vibratory feeder 610 and the first pressing mechanism 400. Specifically, it can adopt a straight or curved metal chute structure, with guide grooves on its inner wall matching the shape of the pins 200, for smoothly transmitting the pins 200 output from the first vibratory feeder 610 to the entrance of the first channel 431. The eighth driving component 630 is an actuator used to push the pins 200 along the first material channel 620. Specifically, it can be a cylinder or a linear motor. Its output end is connected to a push rod or a lever. Through periodic reciprocating motion, it pushes the pins 200 in the first material channel 620 one by one into the first channel 431, thereby preventing the pins 200 from accumulating or getting stuck in the material channel.

[0075] Specifically, the first vibratory feeder 610 organizes the disordered pins 200 into an ordered state through vibration and outputs them along the track to the inlet end of the first material channel 620. The first material channel 620 limits the pins 200 through guide grooves, allowing them to slide along a preset path to a position close to the first channel 431. The eighth drive member 630 applies a pushing force to the pins 200 in the first material channel 620 through a push rod or a lever, causing the pins 200 to overcome friction and move towards the first channel 431. When the pins 200 reach the inlet of the first channel 431, the end of the first pressing member 420 extends into the first channel 431 under the drive of the second drive member 410, pressing the pins 200 into the housing 100.

[0076] In some specific embodiments, a photoelectric sensor may be provided at the end of the first feed channel 620 to detect whether the pin 200 has reached the predetermined position and to feed the signal back to the control system to trigger the action of the eighth drive unit 630.

[0077] This application adds an eighth driving component 630 between the first vibratory plate 610 and the first pressing mechanism 400 to form a segmented conveying structure, which ensures that the pin 200 maintains stable movement during long-distance conveying and avoids the problem of material supply interruption caused by vibration energy attenuation.

[0078] In this embodiment, two second pressing mechanisms 500 are provided. The feeding mechanism 600 further includes a second vibratory feeder 640, a second feed channel 650, and a third feed channel 660. The second feed channel 650 is used to receive the pins 200 transported by the second vibratory feeder 640 and transport them to the second pressing component 520 of one of the second pressing mechanisms 500. The third feed channel 660 is used to receive the pins 200 transported by the second vibratory feeder 640 and transport them to the second pressing component 520 of the other second pressing mechanism 500. The second vibratory feeder 640 is a vibratory feeding device for automatically arranging and transporting the pins 200. Specifically, it can be an electromagnetically driven vibratory feeder, which orients and outputs the disordered pins 200 through vibration. The second feed channel 650 and the third feed channel 660 are conveying paths for guiding the pins 200 from the second vibratory feeder 640 to the pressing component. Specifically, they can be inclined slides or guide rail structures, so that the pins 200 move to the target position under gravity or mechanical push.

[0079] Specifically, when the sliding member 320 moves to the second station, the two second pressing mechanisms 500 are located on opposite sides or at different positions on the same side of the sliding member 320. After the second vibratory feeder 640 outputs the pins 200 in an orderly manner, the second feed channel 650 and the third feed channel 660 guide the pins 200 to the corresponding second pressing members 520. During this process, the third drive members 510 of the two second pressing mechanisms 500 can synchronously or sequentially drive the second pressing members 520 through the through holes 324 of the sliding member 320, pressing the pins 200 into different positions in the housing 100. Through the material distribution design, material supply interference between different pressing mechanisms is avoided, while multi-station synchronous pressing is achieved.

[0080] This application, through the coordinated operation of the dual second pressing mechanism 500 and the feeding mechanism 600, can complete the pressing of multiple pins 200 in one positioning, reduce the number of workpiece movements, realize the synchronous or continuous pressing of pins 200 in multiple positions, and significantly improve assembly efficiency.

[0081] The pin pressing device provided in this application achieves rapid and accurate pressing of the pins 200 on both sides of the housing 100 by switching work positions through the displacement mechanism 300 and combining the coordinated action of the first pressing mechanism 400 and the second pressing mechanism 500 on both sides and the feeding mechanism 600. At the same time, the support component 330, the first pressing component 800 and the pressing component 900 prevent the housing 100 from deforming. It has the advantages of improving production efficiency, realizing synchronous pressing of multiple work positions, avoiding deformation of the housing 100 and improving assembly accuracy.

[0082] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0085] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
