Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a quick logo unlocking mechanism. Background Technology
[0002] In the automotive industry, vehicle emblems are not only important brand identifiers but also serve a decorative function, enhancing the overall aesthetics of the vehicle. However, most vehicle emblems are currently designed to protrude from the vehicle's surface. While this design enhances the emblem's recognizability, it also creates safety hazards. When a pedestrian collides with a vehicle, the protruding emblem is highly likely to become the direct point of impact, causing additional scratches or punctures and other injuries, seriously threatening the pedestrian's life.
[0003] To address these issues, some retractable emblem devices have emerged on the market. These devices are designed to automatically retract into the vehicle when the emblem is subjected to pressure, thereby reducing the risk of injury to pedestrians. However, in practical applications, existing retractable emblem devices have revealed numerous problems. For example, current retractable emblem devices often require multiple mechanical components working together, along with a complex electronic control system to trigger and retract the emblem. Too many mechanical components not only increase the size and weight of the device but also complicate the transmission relationships between them. Under external impact, this can easily lead to component jamming and transmission failure, resulting in insensitive triggering, failure to retract the emblem in time to protect pedestrians, and poor overall reliability and stability of the device. Utility Model Content
[0004] The purpose of this invention is to provide a quick-unlocking mechanism for logos, which has a simple structure, sensitive triggering, good reliability and stability, and strong practicality.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A logo quick-unlocking mechanism includes a logo body, a base, a transmission rod, a main body, a latch, a support spring, and a locking block;
[0007] The logo is located on the top of the base, and the upper end of the transmission rod is fixedly connected to the bottom of the base. The latch is located below the transmission rod, with its middle part hinged to the main body, one end movably connected to the lower part of the transmission rod, and the other end equipped with a barbed lock head that cooperates with the locking block. The support spring is located between the base and the main body and is sleeved on the transmission rod.
[0008] When the logo body is locked, the barbed lock head contacts the top of the locking block, locking the locking block. The support spring provides an upward force to the base and the transmission rod, thereby making the barbed lock head tightly engaged with the top of the locking block and maintaining the locked state.
[0009] When the logo body is subjected to external impact pressure, the logo body triggers the transmission rod to drive the latch to deflect around the main body, and the barbed lock head disengages from the top of the locking block to unlock. After unlocking, the main body drives the logo body to move downward relative to the locking block and retract into the vehicle.
[0010] The technical principle of this invention is as follows: This device primarily utilizes mechanical linkage and spring force to achieve locking and unlocking functions. In the locked state, the support spring's force keeps the base and transmission rod in a specific position, ensuring the hook lock head of the latch engages tightly with the locking block, locking the main body and preventing the emblem from moving. When the emblem is subjected to external impact pressure, the pressure is transmitted to the latch through the base and transmission rod. Using the lever principle, the latch deflects around the main body's hinge point, causing the hook lock head to disengage from the locking block, thus unlocking the device. After unlocking, the main body and its components, including the emblem, retract downwards into the vehicle under gravity.
[0011] Furthermore, the main body includes two parallel plates, with a support fixedly connected between the two plates; the upper and lower ends of the support spring respectively cooperate with the base and the support; the latch is located below the support, and the transmission rod passes through the support and is movably connected to the latch.
[0012] Furthermore, the latch is provided with a hinge pin in the middle, and hinge pin holes are provided on both parallel plates. The latch and the main body are hinged together by the hinge pin and the hinge pin holes.
[0013] A transmission pin is fixed on the transmission rod, and a slotted hole is provided on the lock. The transmission rod and the lock are movably connected through the cooperation of the transmission pin and the slotted hole.
[0014] Furthermore, the main body is also provided with a guide part that cooperates with the locking block, and the locking block and the guide part are slidably connected.
[0015] Furthermore, it also includes a booster spring for assisting the body during its downward movement, with its upper end fixedly connected to the upper part of the body and its lower end fixedly connected to the locking block.
[0016] Furthermore, it also includes a fixed plate and a limiting plate. A connecting rod is fixedly connected to the bottom of the logo body, and the lower end of the connecting rod is fixedly connected to the fixed plate. The limiting plate is fixedly connected to the top of the main body, and the fixed plate is stuck between the limiting plate and the base. The limiting plate also has a through hole for the connecting rod to pass through.
[0017] Furthermore, the area where the upper part of the barbed lock head contacts the edge of the locking block is inclined to form an inclined surface.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This utility model is based on the principle of mechanical linkage and spring force. When the emblem body is subjected to external collision pressure, the pressure is quickly transmitted to the transmission rod through the base. The transmission rod immediately drives the latch to deflect around the hinge point of the main body. The entire process does not require complex signal conversion or electronic control delay. From the occurrence of the collision to the release of the hook lock from the locking block to unlock, the response time is extremely short and the sensitivity is high. It can quickly react to the collision situation, allowing the emblem body to retract into the vehicle in time, effectively reducing the potential damage caused by the collision. The overall reliability and stability are good, and the practicality is strong.
[0020] 2. The device of this utility model mainly consists of several basic components: an emblem body, a base, a transmission rod, a main body, a latch, a support spring, and a locking block. Compared with some complex electronic or hydraulic unlocking devices, this utility model has fewer components and a compact structure, which not only reduces the difficulty and cost of manufacturing but also facilitates installation and layout in automobiles, saving interior space. Furthermore, the connections and transmission relationships between the components are based on common mechanical principles, enabling technicians to quickly master its working principles and operating methods during research, development, production, and maintenance, reducing the time and cost of technical training.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] like Figures 1 to 8 As shown, a logo quick-unlocking mechanism includes a logo body 1, a base 2, a transmission rod 3, a main body 4, a latch 5, a support spring 6, and a locking block 7;
[0034] The logo body 1 is set on the top of the base 2, and the upper end of the transmission rod 3 is fixedly connected to the bottom of the base 2; the latch 5 is located below the transmission rod 3, with its middle part hinged to the main body 4, one end movably connected to the lower part of the transmission rod 3, and the other end provided with a barbed lock head 8 that cooperates with the locking block 7; the support spring 6 is located between the base 2 and the main body 4, and is sleeved on the transmission rod 3.
[0035] When the logo body 1 is locked, the barb lock head 8 contacts the top of the locking block 7 and locks the locking block 7. The support spring 6 provides an upward force to the base 2 and the transmission rod 3, thereby making the barb lock head 8 tightly fastened to the top of the locking block 7 and maintaining the locked state.
[0036] When the logo body 1 is subjected to external impact pressure, the logo body 1 triggers the transmission rod 3 to drive the latch 5 to deflect around the main body 4, and the barbed lock head 8 exits the top of the locking block 7 to achieve unlocking. After unlocking, the main body 4 drives the logo body 1 to move downward relative to the locking block 7 and retract into the vehicle.
[0037] The working principle of this utility model is as follows:
[0038] When the device is locked, the base 2 and the rotating rod tend to move upward under the elastic force of the support spring 6, causing the barbed lock head 8 to be tightly engaged with the top of the locking block 7, preventing the main body 4 from moving downward relative to the locking block 7. When the emblem body 1 is impacted by an external force, under external pressure, the emblem body 1 presses down on the base 2, driving the transmission rod 3 to move downward, and the support spring 6 is compressed by the base 2. Since the transmission rod 3 is movably connected to the latch 5, and the latch 5 is hinged to the main body 4, when the transmission rod 3 moves downward, it causes the end of the latch 5 connected to the transmission rod 3 to deflect downward. According to the lever principle, the end of the latch 5 with the barbed lock head 8 deflects upward, causing the barbed lock head 8 to disengage from the top of the locking block 7, thereby unlocking. After unlocking, the main body 4 is no longer restricted by the locking block 7, and under its own weight, it moves downward relative to the locking block 7. Since the emblem body 1, base 2, transmission rod 3, latch 5, and support spring 6 are all mounted on the main body 4, these components move downward synchronously with the main body 4, and the emblem body 1 retracts into the vehicle.
[0039] This invention is based on the principles of mechanical linkage and spring force. When the emblem body 1 is impacted, the pressure is transmitted through the base 2 to the transmission rod 3, causing the latch 5 to deflect. It requires no complex signal conversion or electronic control, has an extremely short response time and high sensitivity, and can quickly unlock the emblem body 1 to retract into the vehicle to reduce injury. Overall, it exhibits good reliability and stability. Furthermore, this device consists of several basic components, including the emblem body 1. With fewer components and a compact structure, it reduces production difficulty and cost, facilitates automotive installation layout, saves space, and its common mechanical connection and transmission relationships are easy for technicians to understand, reducing technical training costs.
[0040] It is important to note that the design must ensure that the supporting force of the support spring 6 on the base 2 is greater than the weight of the main body 4 and its supporting components. This will prevent the base 2 from moving downwards and causing the latch 5 to deflect during normal use (i.e., when the emblem body 1 is not subjected to external impact). Furthermore, the supporting force must be able to simultaneously counteract the vibration and impact forces during normal vehicle operation to ensure that the latch does not unlock under non-collision conditions.
[0041] In practical application, a limiting plate is also provided below the main body 4. When the main body 4 descends to a certain extent and contacts the limiting plate, the limiting plate will generate an upward supporting force on the main body 4, preventing the main body 4 from descending further, thereby ensuring the safe range of descent of the main body 4 and protecting the entire mechanism and related components inside the vehicle from damage. The vehicle is also equipped with a lifting device fixedly connected to the locking block 7, used to drive the locking block 7 to engage with the latch 5 again after the emblem body 1 retracts into the vehicle. The lifting device is a common device in the prior art, such as a cylinder or ball screw. The principles of the limiting plate and the lifting device are conventional principles in the art, and those skilled in the art can conventionally implement them based on this invention.
[0042] In one embodiment of this utility model, the lifting device is a cylinder, which is disposed below the locking block 7, and the cylinder output shaft is fixedly connected to the bottom of the locking block 7. When it is necessary to move the locking block 7, the cylinder can drive the locking block 7 to move up and down.
[0043] In another embodiment of this utility model, the lifting device is a ball screw, and the locking block 7 is fixedly connected to the nut slider of the ball screw. The drive motor that works with the ball screw drives the screw to rotate, thereby moving the nut slider and further moving the locking block 7. By controlling the forward and reverse rotation of the drive motor, the locking block 7 can be moved up and down.
[0044] The above embodiments are only some implementations of the lifting device of this utility model. In actual application, other lifting devices can also be used as long as they can achieve the corresponding functions of this utility model.
[0045] The specific working principle of the lifting device and other components in this utility model is as follows:
[0046] When the emblem body 1 retracts into the vehicle, the external pressure it experiences disappears. At this time, the compressed support spring 6 returns to its original shape, generating an upward elastic force that causes the base 2 to move upward relative to the main body 4. Since one end of the latch 5 is movably connected to the transmission rod 3, and the other end is equipped with a barbed locking head 8, the upward movement of the base 2 will cause the latch 5 to rotate around the hinge point between its middle part and the main body 4 via the transmission rod 3. This causes the barbed locking head 8 of the latch 5 to deflect towards the locking block 7, preparing for re-locking. At this time, the barbed locking head 8 is located below the locking block 7. When re-locking is required, the lifting device first moves the locking block 7 downward until the locking block 7 moves below the barbed locking head 8, and the barbed locking head 8 can be tightly locked on the top of the locking block 7 again. After the barbed locking head 8 is tightly locked on the top of the locking block 7 again, the lifting device moves the locking block 7 upward. Since the latch 5 is already locked to the locking block 7 by the barbed lock head 8, when the locking block 7 moves upward, it will generate an upward pulling force on the latch 5. The latch 5 is hinged to the main body 4 and is movably connected to the transmission rod 3, so the pulling force will be transmitted to the main body 4, driving the main body 4 and its supporting parts to move upward until the logo body 1 and the locking block 7 return to the initial locked state, and then the lifting device stops operating, completing a complete lock-unlock-relock cycle.
[0047] In practical applications, to ensure that the locking block 7 can move smoothly relative to the main body 4 during the above process, an inclined surface 21 is formed in the area where the upper part of the barbed lock head 8 contacts the edge of the locking block 7, and the edge of the inclined surface 21 is smoothly transitioned. Based on the principle of inclined surface compression, when the locking block 7 moves downward, its edge contacts the inclined surface 21, which will generate a component force on the barbed lock head 8 along the direction of the inclined surface 21, causing the barbed lock head 8 to deflect in the direction of the transmission rod 3, thereby ensuring that the latch 5 will not hinder the movement of the locking block 7 during the descent of the locking block 7.
[0048] Using the device of this invention, after the emblem body 1 retracts into the vehicle and the impact pressure disappears, the support spring 6 quickly returns to its original position, causing the base 2 to move upward relative to the main body 4. This causes the barbed lock head 8 of the latch 5 to deflect towards the locking block 7, preparing for relocking. Furthermore, the entire unlocking and locking process of this invention relies entirely on the interaction between mechanical components, without depending on electronic components or complex control systems. It features high determinism and strong anti-interference capabilities, is unaffected by external factors such as electromagnetic interference and voltage fluctuations, and can operate stably under various harsh environmental conditions. This ensures reliable unlocking when needed and stable locking during normal use.
[0049] like Figures 2 to 8 As shown, in this utility model, the main body 4 includes two parallel plates 9, and a support part 10 is fixedly connected between the two plates 9; the upper and lower ends of the support spring 6 are respectively engaged with the base 2 and the support part 10; the latch 5 is located below the support part 10, and the transmission rod 3 passes through the support part 10 and is movably connected to the latch 5.
[0050] The main body 4 of this utility model includes two parallel plates 9 and a support part 10, which cooperate to form a stable frame structure, providing reliable support and space for the installation and movement of components such as the support spring 6, the base 2, and the connecting rod 19. The two ends of the support spring 6 can be fixedly connected to the base 2 and the support part 10 respectively, or it can be placed directly between the base 2 and the support part 10. In the locked state, the support spring 6 provides an upward force to the base 2 and the transmission rod 3, keeping the entire structure stable and ensuring that the barbed locking head 8 of the latch 5 can be tightly engaged with the top of the locking block 7, thus locking the emblem body 1. The latch 5 is located in the area below the support part 10 between the two plates 9, which can make full use of the internal space of the main body 4, making the layout of each component more compact and reasonable. This not only facilitates installation on automobiles and reduces space occupation, but also makes the relative positional relationship between each component clear, facilitating debugging and maintenance by technicians.
[0051] like Figures 2 to 8As shown, in this utility model, the latch 5 has a hinge pin 11 in the middle, and the two parallel plates 9 each have a hinge pin hole 12. The latch 5 and the main body 4 are hinged together by the hinge pin 11 and the hinge pin hole 12. The latch 5 is hinged to the main body 4 by the hinge pin 11 and the hinge pin hole 12, allowing the latch 5 to move freely and flexibly around the hinge point. When the emblem body 1 is subjected to impact pressure, the latch 5 can quickly respond to the drive of the transmission rod 3 and accurately deflect around the hinge point, realizing the rapid separation of the barbed lock head 8 and the locking block 7, improving the sensitivity and efficiency of unlocking.
[0052] like Figures 1 to 9 As shown, in this utility model, a transmission pin 13 is fixed on the transmission rod 3, and a slotted hole 14 is provided on the latch 5. The transmission rod 3 and the latch 5 are movably connected through the transmission pin 13 and the slotted hole 14. When the emblem body 1 is subjected to external impact pressure, the pressure is transmitted to the transmission rod 3 through the base 2. The transmission rod 3 moves downward, and the transmission pin 13 slides in the slotted hole 14, causing the latch 5 to deflect around the hinge point, so that the barbed lock head 8 exits the top of the locking block 7, thereby unlocking. Afterwards, the main body 4 and the emblem body 1 and other components move downward relative to the locking block 7 and retract into the vehicle under the action of gravity.
[0053] like Figures 1 to 8 As shown, in this utility model, the main body 4 is also provided with a guide part 15 that cooperates with the locking block 7, and the locking block 7 and the guide part 15 are slidably connected; after unlocking, the main body 4 slides downward relative to the locking block 7, causing the logo body 1 to move downward and retract into the vehicle.
[0054] In one embodiment of this utility model, the guide portion 15 is a plate-shaped structure fixed to the sides of two plates 9, with a locking opening at its center for the latch 5 to pass through. Raised guide rails 22 are vertically arranged on both sides of the locking opening on the guide portion 15. The locking block 7 has a sliding groove 23 that matches the raised guide rail 22. The sliding groove 23 can be a straight groove, a dovetail groove, or a T-shaped groove, etc. The sliding groove 23 cooperates with the raised guide rail 22, allowing the locking block 7 to slide relative to the guide portion 15 along the direction of the sliding groove 23. The sliding connection between the locking block 7 and the guide portion 15 provides a precise guiding path for the movement of the main body 4 relative to the locking block 7, ensuring that the main body 4 can only slide along the direction specified by the guide portion 15 after unlocking. This avoids instability such as offset and swaying during the movement of the main body 4, ensuring the accurate and smooth retraction of the emblem body 1 into the vehicle, and improving the precision and reliability of the entire mechanism's movement. In other embodiments, the positions of the raised guide rail 22 and the slide groove 23 can be interchanged, that is, the slide groove 23 is provided on the guide portion 15 and the raised guide rail 22 is provided on the locking block 7.
[0055] like Figure 1 , Figure 2 , Figure 3, Figure 5 and Figure 7 As shown, this invention also includes a booster spring 16 for assisting the downward movement of the main body 4. Its upper end is fixedly connected to the upper part of the main body 4, and its lower end is fixedly connected to the locking block 7. When the emblem body 1 is locked, the booster spring 16 is in a stretched state, storing a certain amount of elastic potential energy. When the emblem body 1 is unlocked by external impact pressure, the main body 4 begins to slide downward relative to the locking block 7. The elastic restoring force generated by the stretched booster spring 16 begins to function, applying a downward pulling force to the main body 4. This pulling force, combined with the weight of the main body 4, assists the main body 4 in sliding downward, accelerating the process of the main body 4 moving the emblem body 1 downward and retracting it into the vehicle. In emergency situations such as collisions, faster unlocking and retraction speeds better protect the emblem body 1, reducing damage caused by collisions and improving the overall safety performance of the vehicle.
[0056] like Figures 1 to 8 As shown, this utility model also includes a fixed plate 17 and a limiting plate 18. A connecting rod 19 is fixedly connected to the bottom of the logo body 1, and the lower end of the connecting rod 19 is fixedly connected to the fixed plate 17. The limiting plate 18 is fixedly connected to the top of the main body 4, and the fixed plate 17 is stuck between the limiting plate 18 and the base 2. A through hole 20 is also provided on the limiting plate 18 for the connecting rod 19 to pass through.
[0057] To ensure connection stability, the fixed plate 17 and the base 2 are fixedly connected in this invention. Specifically, a snap-fit method can be used, such as setting snap-fit blocks on the outer periphery of the fixed plate 17 and setting corresponding slots on the base 2, with the snap-fit blocks tightly embedded in the slots to achieve a fixed connection. Because the fixed plate 17 and the base 2 are fixedly connected, the base 2 will not loosen, shake, or separate from the fixed plate 17 due to the instantaneous force generated during the unlocking process. Instead, it can move downwards and retract into the vehicle along with the fixed plate 17, the connecting rod 19, and the emblem body 1.
[0058] The lower end of the connecting rod 19 at the bottom of the logo body 1 is fixedly connected to the fixing plate 17, allowing the fixing plate 17 to move together with the logo and the connecting rod 19. The through hole 20 on the limiting plate 18, through which the connecting rod 19 passes, ensures that the connecting rod 19 can move freely up and down, and also provides some guidance for the direction of movement of the connecting rod 19. The fixing plate 17 is engaged between the limiting plate 18 and the base 2, forming a sandwich-like structure. When the logo body 1 is in normal use (i.e., locked state), the fixing plate 17 is constrained within a specific range by the downward limiting force of the limiting plate 18 and the upward supporting force of the base 2, preventing it from popping upwards.
[0059] The working process of this utility model device is described in detail below, mainly including the following three processes.
[0060] I. Locked State
[0061] When the logo quick-unlock mechanism is locked, the logo body 1 is stably positioned on top of the base 2, and the upper end of the transmission rod 3 is tightly fixedly connected to the bottom of the base 2. A support spring 6 is sleeved on the transmission rod 3, with its two ends engaging with the support portions 10 on the base 2 and the main body 4 respectively, providing an upward force to the base 2 and the transmission rod 3. The middle of the latch 5 is hinged to the main body 4 via a hinge pin 11, one end is movably connected to the lower part of the transmission rod 3 via a transmission pin 13 and a slotted hole 14, and the other end's barbed lock head 8 contacts and locks the top of the locking block 7 fixed to the vehicle body. At this time, under the elastic force of the support spring 6, the barbed lock head 8 is tightly engaged with the top of the locking block 7, preventing the main body 4 from moving downwards relative to the locking block 7. Simultaneously, the main body 4 has a guide portion 15 that engages with the locking block 7, providing precise guidance for subsequent movement of the main body 4 relative to the locking block 7. The upper end of the assist spring 16 is fixedly connected to the upper part of the main body 4, and the lower end is fixedly connected to the locking block 7, storing elastic potential energy in a stretched state. A connecting rod 19 is fixedly connected to the bottom of the logo body 1. The lower end of the connecting rod 19 is fixedly connected to the fixed plate 17. The limiting plate 18 is fixedly connected to the top of the main body 4, and the fixed plate 17 is locked between the limiting plate 18 and the base 2. A through hole 20 is opened on the limiting plate 18 for the connecting rod 19 to pass through, guide the movement direction of the connecting rod 19, and limit the base 2 within a specific range to prevent it from popping up and ensure the stability of the logo body 1.
[0062] II. Unlocking Process
[0063] When the emblem body 1 is subjected to external impact pressure, the pressure is transmitted to the base 2 through the emblem body 1. The base 2 drives the transmission rod 3 to move downward, and the support spring 6 is further compressed. Since the transmission rod 3 and the latch 5 are movably connected through the transmission pin 13 and the strip hole 14, and the latch 5 is hinged to the main body 4, the downward movement of the transmission rod 3 causes the end of the latch 5 connected to the transmission rod 3 to deflect downward, and the end of the latch 5 with the barbed lock head 8 deflects upward, so that the barbed lock head 8 disengages from the top of the locking block 7, thereby unlocking. After unlocking, the elastic restoring force generated by the stretching of the assist spring 16 takes effect, applying a downward pulling force to the main body 4. This pulling force, together with the weight of the main body 4 itself, provides assistance for the main body 4 to slide down. Under the action of its own weight and the pulling force of the assist spring 16, the main body 4 slides downward relative to the locking block 7 along the guide part 15, causing the emblem body 1, base 2, transmission rod 3, latch 5, and support spring 6, and other components set on the main body 4, to move downward synchronously, so that the emblem body 1 retracts into the vehicle.
[0064] III. Relocking Process
[0065] After the emblem body 1 retracts into the vehicle, the external pressure disappears, and the compressed support spring 6 returns to its original shape, generating an upward elastic force that causes the base 2 to move upward relative to the main body 4. The upward movement of the base 2, via the transmission rod 3, causes the latch 5 to rotate around the hinge point, deflecting the barbed head 8 of the latch 5 towards the locking block 7, preparing for relocking. At this time, the lifting device moves the locking block 7 downward first. To ensure that the locking block 7 can move smoothly relative to the main body 4, an inclined surface 21 is formed in the area where the upper part of the barbed head 8 contacts the edge of the locking block 7. When the locking block 7 moves downward, its edge contacts the inclined surface 21, generating a component force along the inclined surface 21 on the barbed head 8, causing the barbed head 8 to deflect towards the transmission rod 3, preventing the latch 5 from obstructing the movement of the locking block 7. When the barbed head 8 can once again lock tightly onto the top of the locking block 7, the lifting device moves the locking block 7 upward. Since the latch 5 is locked together with the locking block 7 by the barbed lock head 8, when the locking block 7 moves upward, it generates an upward pulling force on the latch 5. This pulling force is transmitted to the main body 4, causing the main body 4 and its supporting components to move upward until the logo body 1 protrudes out of the vehicle, returning to the initial locked state, completing a complete lock-unlock-relock cycle.
[0066] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the spirit of this utility model should be included within the protection scope of this utility model.
