[0031] The present invention provides a safety handle and a car. Figures 1 to 4 The present invention provides a safety handle and a car according to an embodiment of the present invention.

[0032] Please also read Figure 1 to Figure 2The safety handle and the car include two mounting brackets 3, two bases 2, a handle body 1 and a rebound component 4, wherein the two mounting brackets 3 are arranged at intervals to fix the car body, the two bases 2 are respectively installed on the two mounting brackets 3, and the two ends of the handle body 1 are respectively rotatably installed on one of the bases 2, so that the handle body 1 has an initial position and a reset position, and the rebound component 4 is arranged between the base 2 and the handle body 1 to drive the handle body 1 to rotate from the reset position toward the initial position.

[0033] The safety handle is mainly used to provide a safety auxiliary device for the front passenger and the passengers in the back seat. When the car shakes, the front passenger and the passengers in the back seat can use the safety handle to stabilize themselves, reduce the frequency of collision between the body and the car body during shaking, and thus reduce the impact damage to the front passenger and the passengers in the back seat. Therefore, the safety handle is set on the ceiling of the front passenger and the back seat.

[0034] When installing the handle body 1, first install the two mounting brackets 3 on the car body. The two mounting brackets 3 are installed at a certain distance according to the spacing between the two ends of the safety handle body 1. After the mounting brackets 3 are installed, the two bases 2 are respectively installed on the two mounting brackets 3, and then the two ends of the mounting handle are rotated and installed on the two bases 2, so that the safety handle body 1 is in the initial position when not in use, and is rotated to any angle when in use. When in use, the safety handle is rotated to the reset position and then the hand is released, and the rebound component 4 set between the base 2 and the handle body 1 will drive the safety handle body 1 to rotate toward the initial position until it fits with the car body again and stops rotating.

[0035] During the installation process, it is necessary to ensure that the safety handle body 1 can be located in the initial position when not in use. The purpose of doing this is to ensure that when the safety handle needs to be used, it can be easily rotated to any angle and reach the reset position. When the safety handle is rotated to the reset position and the hand is released, the rebound component 4 set between the base 2 and the handle body 1 will come into play. This rebound component 4 will drive the safety handle body 1 to approach and rotate toward the initial position until the safety handle body 1 is tightly fitted with the car body again and stops rotating. This not only ensures the convenience of use of the safety handle, but also ensures that it can remain in a stable position when not in use, avoiding shaking or accidental rotation, thereby improving overall safety.

[0036] The rebound component 4 mainly utilizes elastic potential energy to complete the resetting work of the handle body 1. Therefore, the elastic part with elastic potential energy used in the rebound component 4 ensures that the rigidity is strong enough. However, manpower is limited. When using the safety handle, the passenger needs to rotate it to a certain angle. Rotating the safety handle requires a certain amount of effort. The stronger the rigidity of the elastic part, the more effort is consumed, and the shorter the time that the safety handle can be held. Therefore, it is necessary to limit the rigidity of the elastic part to ensure that the rigidity of the elastic part can ensure that the safety handle returns normally while not consuming too much effort when used. The material of the torsion spring 41 is usually selected from metal materials with good elasticity and fatigue resistance, such as stainless steel or special alloys, to ensure that it will not break or degrade in performance during long-term use. The size design of the torsion spring 41 needs to be determined according to the frequency of use of the safety handle, the expected service life and the usage habits of the passengers, to ensure that while providing sufficient rebound force, it will not cause excessive operating resistance to the passengers.

[0037] In addition, in order to further improve the user experience of the safety handle, the present invention also takes into account the surface treatment of the handle body 1. The surface of the handle body 1 can adopt anti-slip materials, such as rubber or soft plastic, to increase friction and prevent hands from slipping when the car shakes. At the same time, the shape design of the handle body 1 also takes into account ergonomic principles to adapt to the hand holding habits of different passengers and provide a comfortable grip.

[0038] Therefore, in the technical solution provided by the present invention, the two mounting brackets 3 are arranged at intervals to fix the automobile body, the two bases 2 are respectively installed on the two mounting brackets 3, and the two ends of the handle body 1 are respectively rotatably installed on one of the bases 2, so that the handle body 1 has an initial position and a reset position, and the rebound component 4 is arranged between the base 2 and the handle body 1 to drive the handle body 1 to rotate from the reset position toward the initial position, and the handle body 1 is driven by the rebound component 4 to quickly return from the reset position to the initial position, so that it is convenient for the user to turn the safety handle for use at any time, and the rebound component 4 reduces the return speed, thereby reducing the damage to the safety handle when it returns and the damage to the automobile body.

[0039] Please also read Figure 3 to Figure 4 The rebound component 4 utilizes an elastic member to rotate the handle body 1 back to the initial position. Specifically, in an embodiment of the present invention, a rotating shaft is provided on the base 2, and the handle body 1 is rotatably mounted on the rotating shaft. The rebound component 4 includes a torsion spring 41 sleeved on one of the rotating shafts, one end of the torsion spring 41 is fixedly provided on the base 2, and the other end is abutted against the handle body 1.

[0040] When the handle body 1 rotates, the torsion spring 41 is pushed against one end of the handle body 1, so that the torsion spring 41 is compressed. When the handle body 1 is released, the torsion spring 41 releases its elastic potential energy and pushes the handle body 1 to rotate to the initial position with the help of the end against the handle body 1 until the handle body 1 fits with the vehicle body again.

[0041] In an embodiment of the present invention, the rebound component 4 realizes the function of automatically rotating the handle body 1 to the initial position by using an elastic element. Specifically, a rotating shaft is designed and installed on the base 2, and the handle body 1 is designed to be able to rotate around this rotating shaft. When the user operates the handle body 1 to rotate, this end of the torsion spring 41 will be pushed as the handle body 1 rotates, so that the torsion spring 41 is compressed. This compressed state stores elastic potential energy. When the user releases the handle body 1, the stored elastic potential energy begins to be released. The other end of the torsion spring 41 applies a force by abutting against the contact point on the handle body 1, pushing the handle body 1 to rotate to the initial position. This rotation action will continue until the handle body 1 completely returns to the initial position and fits tightly with the vehicle body, thereby ensuring that the handle body 1 can automatically reset after use to keep the vehicle clean and beautiful.

[0042] Furthermore, the cross section of the torsion spring 41 is gradually reduced from one end fixed on the base 2 toward the other end.

[0043] The cross-sectional shape of the torsion spring 41 starts from one end being fixed on the base 2 and gradually decreases along its length direction toward the other end. Specifically, the cross-sectional size of the torsion spring 41 gradually decreases from the fixed end to form a tapered structure. This torsion spring 41 can distribute stress more evenly when subjected to force, thereby improving its overall stability and service life. Through this tapered cross-sectional design, the torsion spring 41 can better exert its elasticity and energy storage functions when subjected to torsional torque, thereby improving the efficient and reliable operation of the entire mechanical system.

[0044] In addition, the torsion spring 41 with a tapered cross-section design is also more economical in the manufacturing process because it can use less material to achieve the required mechanical properties. This design not only reduces weight but is also more convenient in installation and maintenance. Since the stress distribution of the torsion spring 41 is more uniform, the fatigue life of the torsion spring 41 is extended during long-term use, reducing the risk of safety handle failure due to damage to the torsion spring 41.

[0045] Furthermore, the rebound assembly 4 further includes a damping member 42 sleeved on the other rotating shaft, and the damping member 42 is used to limit the speed at which the handle body 1 rotates from the reset position toward the initial position.

[0046] The function of the damping member 42 is to limit the speed at which the handle body 1 rotates from its reset position to the initial position. Specifically, when the user operates the handle and causes it to deviate from the initial position, the spring or other elastic element in the rebound assembly 4 will generate a force causing the handle body 1 to tend to return to the initial position. However, in order to ensure that this process is not too rapid, the damping member 42 is used to slow down the rotation speed. The damping member 42 can effectively control the rotation speed of the handle body 1 so that it remains stable and controllable during the process of returning to the initial position, thereby improving the overall operating experience and safety.

[0047] There are various structures of the damping element 42, among which the damping element 42 can adopt fluid damping technology to adjust the rotation speed through the flow resistance of liquid or gas. In the process of the handle body 1 rotating from the reset position to the initial position, the fluid inside the damping element 42 flows in a specific channel to generate resistance, thereby slowing down the rotation speed. It can not only prevent the handle from causing accidental injury to the user due to rapid rebound, but also reduce mechanical wear and extend the service life of the handle.

[0048] In addition, the damping element 42 can also adopt friction damping technology to control the rotation speed through the friction force between the contact surfaces. For example, the damping element 42 has one or more friction surfaces. When the handle body 1 rotates, these friction surfaces interact with each other to generate resistance, thereby achieving the purpose of slowing down the rotation speed. Friction damping technology is simple and reliable, easy to maintain, and low in cost. It is suitable for use in cost-sensitive applications. Whether it is fluid damping or friction damping, they provide a safer and more comfortable use experience for the safety handle, ensuring the stability and reliability of the handle under various operating conditions.

[0049] The base 2 needs to occupy a certain space. In order to reduce the space occupied by the entire safety handle, the base 2 can be set inside the safety handle. Specifically, in the technical solution of the present invention, a receiving groove is opened on the handle body 1, and the receiving groove is used to receive the base 2.

[0050] A receiving groove is opened on the main structure of the safety handle. The size and shape of the receiving groove can accommodate the base 2, so that the base 2 can be embedded in the handle body 1, thereby greatly reducing the external occupied space. Such a structure not only makes the overall structure more compact, but also improves the flexibility and aesthetics of installation.

[0051] Embedding the base 2 into the handle body 1 makes the overall structure more compact. This compact structure makes the safety handle more flexible during installation and can adapt to more types of installation environments, whether it is a narrow space or a limited installation surface, it can easily cope with it. Secondly, this design also improves the overall aesthetics. Since the base 2 is hidden inside the handle, no extra parts can be seen from the outside, making the entire safety handle look more simple and beautiful, in line with the aesthetic trend of modern design.

[0052] Furthermore, the mounting bracket 3 is provided with a plurality of mounting holes, and the base 2 is provided with a plurality of positioning pins 21 , and the plurality of positioning pins 21 are used to be inserted into the positioning holes.

[0053] A plurality of mounting holes are provided on the mounting bracket 3, and these mounting holes are evenly distributed to facilitate subsequent mounting and fixing operations. At the same time, a plurality of positioning pins 21 are provided at corresponding positions of the base 2. The function of these positioning pins 21 is to ensure accurate docking and fixation between the mounting bracket 3 and the base 2. Specifically, these positioning pins 21 can be inserted into the positioning holes on the mounting bracket 3, so as to achieve a close fit between the two. Moreover, after these positioning pins 21 are inserted into the positioning holes, it is difficult for the mounting bracket 3 and the base 2 to rotate under the action of external force when they are connected together, thereby improving the installation accuracy.

[0054] The locating pins 21 can be inserted into the locating holes on the mounting bracket 3 to achieve a tight fit between the two. After the locating pins 21 are inserted into the locating holes, it is difficult for the mounting bracket 3 and the base 2 to rotate under the action of external force when they are connected together, thereby improving the accuracy and reliability of the installation. In order to ensure the stable installation of the safety handle on the car body, the base 2 usually adopts high-strength metal materials, such as aluminum alloy or stainless steel. These materials not only have good mechanical properties, but also can withstand the vibration and impact generated during the operation of the car, thereby ensuring the stability and reliability of the safety handle under various road conditions. In addition, the surface of the base 2 can be specially treated, such as anodizing or plating, to improve its corrosion resistance and wear resistance, thereby extending the service life of the entire safety handle. Through these surface treatment processes, the base 2 is not only more beautiful in appearance, but also can better resist the influence of harsh environment during actual use, ensuring the long-term stability and durability of the safety handle.

[0055] Furthermore, at least one of the bases 2 extends laterally to form a support portion 22 , and a hook 221 is disposed on the support portion 22 .

[0056] Through this hook 221, the user can easily hang some lightweight items, such as keys, small tools or other small objects, which not only effectively saves space but also significantly improves the overall efficiency of use. The existence of the hook 221 provides a neat storage location for items that may have been messy, making it more convenient and efficient for the user to use the base 2. In addition, the design of this hook 221 also has a certain degree of flexibility and can be adjusted according to the specific needs of the user to accommodate items of different sizes and shapes.

[0057] The mounting bracket 3 is usually fixed to the upper plate of the center pillar by welding, but the welding process is long, which not only takes a long time but also has a certain impact on the size of the mounting bracket 3 after being fixed, resulting in the pin shaft 11 being unable to be fully aligned during installation, and thus causing the subsequent safety handle to be unable to be fully reset when returning to its original position. Therefore, the mounting bracket 3 is changed to be installed during disassembly to facilitate the replacement of unsuitable mounting brackets 3. Specifically, the two mounting brackets 3 are detachably installed on the automobile body.

[0058] By using bolts or screws for connection, the time required for installation is shortened. At the same time, this connection method can ensure the accuracy of the installation process and avoid safety hazards caused by improper installation. In addition, the use of a disassembly installation method makes subsequent maintenance and replacement work more convenient, thereby improving the reliability and service life of the safety handle, and ensuring that it remains stable under tension and pressure, improving the stability of the safety handle during vehicle operation, and ensuring its functionality so that it can function reliably in various situations.

[0059] The safety handle can also be provided with an adjustable telescopic rod, which can adjust the length according to the needs of the user. The end of the telescopic rod is provided with a clamping device, which can be firmly clamped on the headrest or backrest of the car seat, thereby providing a stable support point for the user. This design not only increases the scope of application of the handle, but also enables the handle to play its due role in different models, enhancing the versatility of the product. An easy-to-operate installation and disassembly mechanism can also be set. Users can easily install or replace the handle according to personal preferences and actual needs without professional tools or complicated operating steps. This design not only facilitates the user, but also reduces the difficulty and cost of subsequent maintenance.

[0060] Furthermore, screws are fixedly provided on the two mounting brackets 3 , and the threaded parts of the screws pass through the base 2 .

[0061] Screws are fixed on the two mounting brackets 3 respectively, and the threaded parts of these screws pass through the base 2, thereby ensuring a tight connection between the screws and the base 2. The two mounting brackets 3 are not only firmly connected to the base 2 through the screws, but also the heads of the screws are firmly fixed to the surfaces of the mounting brackets 3, effectively preventing the screws from loosening during use. In this way, the stability and durability of the entire structure are significantly improved.

[0062] In addition, in order to further enhance the connection strength, the threaded portion of the screw passes through the interior of the base 2, ensuring the stability and durability of the entire structure. At the same time, an additional anti-slip design is adopted between the mounting bracket 3 and the base 2. This design further enhances the connection strength between them by increasing the contact area and friction. This anti-slip design enables the entire device to maintain excellent stability and reliability in various complex environments, regardless of vibration, impact or other external forces, thereby comprehensively improving the performance of the entire device and ensuring its efficiency and safety in practical applications.

[0063] The present invention also proposes a car, which includes a safety handle. The specific structure of the safety handle refers to the above-mentioned embodiment. Since the car adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
