Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle parts technology, and more specifically, it relates to an adjustable spring for new energy vehicles with an overload protection structure. Background Technology

[0002] In the complex electrical systems of new energy vehicles, spring contacts play an indispensable role as a key mechanical and electrical connection element. Spring contacts are usually made of metal materials with good conductivity and elasticity, such as copper alloys or stainless steel. Their design purpose is to achieve stable electrical contact through elastic deformation, while being able to adapt to certain mechanical stresses and thermal expansion.

[0003] Currently, during operation, in the event of abnormal conditions such as battery short circuits, motor overloads, or external collisions, the spring may be subjected to current or mechanical stress exceeding its design limits. In such situations, the elastic material of the spring may undergo permanent deformation due to excessive stretching or compression. Once the deformation exceeds its elastic limit, the spring's elastic properties will be destroyed, preventing it from returning to its initial state and thus maintaining proper electrical contact. Furthermore, deformed springs may interfere with other components, affecting normal vehicle operation and potentially causing short circuits in high-voltage circuits, endangering the safety of passengers and the vehicle. Utility Model Content

[0004] To address the issue of springs being subjected to excessive current or mechanical stress beyond their design limits during operation, such as battery short circuits, motor overloads, or external collisions, this invention aims to provide an adjustable spring for new energy vehicles with an overload protection structure. In such cases, the spring's elastic material may undergo permanent deformation due to excessive stretching or compression. Once the deformation exceeds its elastic limit, the spring's elastic properties are destroyed, preventing it from returning to its initial state and maintaining proper electrical contact. Furthermore, the deformed spring may interfere with other components, affecting normal vehicle operation and potentially causing short circuits in high-voltage circuits, endangering passenger and vehicle safety. The purpose of this invention is to provide an adjustable spring for new energy vehicles with an overload protection structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable spring for new energy vehicles with an overload protection structure, including a spring body, and an alarm component is fixedly connected to the bottom of the spring body.

[0007] The spring body includes a spring fixing end, an elastic contact end fixedly connected to the side of the spring fixing end, a sliding hole opened inside the elastic contact end, a limit rod provided inside the sliding hole, a maximum range limit block and a minimum range limit block fixedly connected to the side of the limit rod, a threaded hole opened inside the elastic contact end, an adjusting screw provided inside the threaded hole, and a spring provided on the side of the adjusting screw.

[0008] As a preferred embodiment of this utility model, a fixing seat is fixedly connected to the side of the spring fixing end, and the fixing seat is fixedly connected to the limiting rod.

[0009] As a preferred embodiment of this utility model, the limiting rod slides inside the sliding hole, and the threaded hole is threadedly connected to the adjusting screw.

[0010] In a preferred embodiment of this utility model, the spring is elastically connected to the adjusting screw, and a damper is fixedly connected to the side of the spring plate fixing end, and the damper is elastically connected to the spring.

[0011] As a preferred embodiment of this utility model, two dampers, springs, and adjusting screws are provided, and two threaded holes are provided.

[0012] As a preferred technical solution of this utility model, the spring clip fixing end is fixed to the corresponding component of the new energy vehicle by welding.

[0013] As a preferred embodiment of this utility model, the alarm component includes a base, and a protective cover is fixedly connected to the bottom of the base.

[0014] As a preferred embodiment of this utility model, an alarm is fixedly connected inside the protective cover, and a strain sensor is installed inside the protective cover.

[0015] The advantages of this utility model are:

[0016] 1. This utility model utilizes the sliding of the limiting rod inside the sliding hole during elastic deformation of the elastic contact end, in conjunction with the minimum range limiting block and the maximum range limiting block, to limit further deformation of the spring body, thereby providing deformation overload protection for the spring. When the spring undergoes elastic deformation, the limiting rod will slide inside the sliding hole. This sliding mechanism allows the spring to deform freely within the normal working range, while the boundary of the sliding hole limits the movement range of the limiting rod, enabling the spring to deform freely within a certain range, thus maintaining good electrical contact and mechanical stability.

[0017] 2. This utility model adjusts the position of the adjusting screw to change the compression of the spring, thereby deforming the elastic contact end. This allows for adjustment of the deformation degree of the adjusting spring body to adapt to different electrical connection requirements. By rotating the adjusting screw, the compression of the spring can be precisely controlled. When the adjusting screw is tightened inward, the spring is further compressed; when the adjusting screw is loosened outward, the compression of the spring decreases, and the pressure also decreases. This design allows the spring to flexibly adjust the contact pressure according to different electrical connection requirements, ensuring a stable electrical connection. Attached Figure Description

The use of terminology herein is intended to specifically describe embodiments and not to limit the scope of the invention. Furthermore, the term "and / or" signifies all possible combinations encompassing any one or more of the listed items.

[0026] Example 1:

[0027] Please see Figures 1-4 Structural diagram; the present invention provides the following technical solution:

[0028] Specifically, it refers to an adjustable spring for new energy vehicles with an overload protection structure, including a spring body 1, and an alarm component 2 fixedly connected to the bottom of the spring body 1.

[0029] The spring body 1 includes a spring fixing end 101, and an elastic contact end 102 is fixedly connected to the side of the spring fixing end 101. A sliding hole 107 is formed inside the elastic contact end 102, and a limit rod 104 is provided inside the sliding hole 107. A maximum range limit block 105 and a minimum range limit block 106 are fixedly connected to the side of the limit rod 104. A threaded hole 111 is formed inside the elastic contact end 102, and an adjusting screw 110 is provided inside the threaded hole 111. A spring 109 is provided on the side of the adjusting screw 110. The elastic contact end 102 is used for... When the spring undergoes elastic deformation, the limiting rod 104 slides inside the sliding hole 107, in conjunction with the minimum range limiting block 106 and the maximum range limiting block 105, thereby limiting further deformation of the spring and providing deformation overload protection for the spring. When the spring undergoes elastic deformation, the limiting rod 104 will slide inside the sliding hole 107. This sliding mechanism allows the spring to deform freely within the normal operating range, while the boundary of the sliding hole 107 limits the movement range of the limiting rod 104, enabling the spring to deform freely within a certain range, thereby maintaining good electrical contact and mechanical stability.

[0030] The working principle of the adjustable spring with overload protection structure for new energy vehicles provided by this utility model is as follows:

[0031] Working Principle: To achieve precise control over the deformation of the spring sheet, a limiting rod 104 and a sliding hole 107 are incorporated into the design. When the spring sheet undergoes elastic deformation, the limiting rod 104 slides within the sliding hole 107. This sliding mechanism allows the spring sheet to deform freely within its normal operating range. Furthermore, the combination of an adjusting screw 110 and a spring 109 allows for flexible adjustment of the elastic contact end 102 of the spring sheet according to actual needs. By rotating the adjusting screw 110, the compression of the spring 109 can be changed, thereby adjusting the deformation of the elastic contact end 102 of the spring sheet. The elastic contact end 102 of the spring sheet experiences a greater elastic force, thus increasing contact... Conversely, when the adjusting screw 110 is loosened outwards, the compression of the spring 109 decreases, the elastic force on the elastic contact end 102 of the spring sheet decreases, and the contact pressure also decreases. At the same time, the movement range of the limit rod 104 is limited by the boundary of the sliding hole 107. A minimum range limit block 106 is provided, which ensures that the spring sheet maintains a certain initial position and shape when it is not under force or under slight force. This design can prevent unnecessary deformation of the spring sheet in the unforced state, and at the same time provide a stable reference point for the normal operation of the spring sheet. The presence of the maximum range limit block 105 can also prevent the spring sheet from losing its elastic contact ability due to excessive relaxation under low stress.

[0032] Example 2:

[0033] Based on Specific Embodiment 1, the difference in this embodiment is as follows:

[0034] like Figure 1 , Figure 2 and Figure 3As shown, a fixing seat 103 is fixedly connected to the side of the spring fixing end 101. The fixing seat 103 is fixedly connected to the limiting rod 104, which slides inside the sliding hole 107. The threaded hole 111 is threadedly connected to the adjusting screw 110, and the spring 109 is elastically connected to the adjusting screw 110. A damper 108 is fixedly connected to the side of the spring fixing end 101, and the damper 108 is elastically connected to the spring 109. Two dampers 108, springs 109, and adjusting screws 110 are provided, and two threaded holes 111 are provided. The spring fixing end 101 is fixed to the corresponding component of the new energy vehicle by welding. By adjusting the position of the adjusting screw 110, the compression of the spring 109 is changed, which in turn deforms the elastic contact end 102. This allows for adjustment of the deformation degree of the adjusting spring to adapt to different electrical connection requirements. By rotating the adjusting screw 110, the compression of the spring 109 can be precisely controlled. When the adjusting screw 110 is tightened inward, the spring 109 is further compressed. When the adjusting screw 110 is loosened outward, the compression of the spring 109 decreases, and the pressure also decreases. This design allows the spring to flexibly adjust the contact pressure according to different electrical connection requirements, ensuring a stable electrical connection.

[0035] Example 3:

[0036] Based on specific embodiment two, the difference in this embodiment is as follows:

[0037] like Figure 1 and Figure 4 As shown, the alarm component 2 includes a base 201, a protective cover 202 is fixedly connected to the bottom of the base 201, an alarm 203 is fixedly connected inside the protective cover 202, and a strain sensor 204 is installed inside the protective cover 202. The alarm 203 and the strain sensor 204 can be used to activate the alarm 203 when the spring is close to an overload state and the degree of deformation exceeds a preset threshold, so as to issue an alarm signal and remind the user to take timely measures.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
