Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, specifically to an anti-disassembly screw component for electric vehicle batteries. Background Technology

[0002] With the increasing popularity of electric vehicles (such as electric bicycles and electric tricycles), the safety, theft prevention, and anti-illegal disassembly requirements of batteries, as core power components, are becoming increasingly prominent. Currently, most electric vehicle batteries on the market are secured using ordinary screws to directly connect the battery compartment to the battery, or simply using a simple clip structure for positioning, which has the following significant drawbacks:

[0003] Ordinary screws can be easily removed with conventional tools, making it easy for criminals to steal batteries and causing property loss to users. At the same time, illegal disassembly may damage the battery compartment structure, affecting the overall safety of the electric vehicle. Traditional clips or single screw fixing methods are prone to loosening during the bumpy ride of the electric vehicle, resulting in poor contact between the battery and the electrodes, causing problems such as power outages and reduced range. In fact, battery shaking can even create safety hazards. Most fixing structures do not have sealing components, allowing rainwater and dust to enter the battery compartment through gaps, corroding the battery terminals or circuit boards, shortening battery life, and increasing the probability of failure. Furthermore, some anti-tamper structures use complex multi-step disassembly processes to improve safety, which inconveniences users when maintaining and replacing batteries. In view of this, we propose an anti-tamper screw component for electric vehicle batteries to solve the existing problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-tamper screw component for electric vehicle batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-tamper screw component for an electric vehicle battery, comprising a battery compartment, a placement slot, an anti-tamper mechanism, a control compartment, and a stabilizing component. The battery compartment has a placement slot, and the placement slot contains a control compartment. A battery is detachably placed on one side of the control compartment within the placement slot. A stabilizing component is placed on the upper side of the battery. A threaded anti-tamper mechanism is provided between the placement slot and the battery.

[0006] Preferably, the anti-tamper mechanism includes a cover plate, a movable shaft, a guide groove, a transmission groove, a knob, a rotating seat, a threaded rod, a rotating shaft, a first synchronous pulley, a synchronous belt, a second synchronous pulley, a rotating rod, a first transmission wheel, and a second transmission wheel. A rotating seat is provided in the placement groove, and a rotating shaft is movably connected to the rotating seat. The cover plate is movably connected to the rotating seat through the rotating shaft. Guide grooves are symmetrically opened on the cover plate, and grooves are symmetrically opened in the placement groove. A rotating shaft is movably connected to the groove. The rotating shaft has a threaded structure, and a threaded rod is movably connected to the rotating shaft. The threads of the stabilizing component and the threaded rod are mutually engaged.

[0007] Preferably, the battery compartment has a transmission groove, a first synchronous wheel is fixedly connected to the rotating shaft in the transmission groove, a second transmission wheel is provided in the transmission groove on the movable shaft, a rotating rod is movably connected in the transmission groove, a first transmission wheel is provided on the side of the rotating rod near the second transmission wheel, and the first transmission wheel and the second transmission wheel mesh with each other.

[0008] Preferably, a second synchronous pulley is provided on the side of the rotating rod away from the first transmission wheel, and a synchronous belt is provided between the first synchronous pulley and the second synchronous pulley.

[0009] Preferably, the cover plate is provided with a gasket on the guide groove, the gasket is made of rubber material, and the cover plate is provided with an anti-tamper cover near the threaded rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The cover plate rotates to the closed position around the rotating shaft via the rotating seat. During operation, the rotating shaft is rotated by the external rotating rod and the rotating knob. The first synchronous wheel below the rotating shaft drives the second synchronous wheel to rotate via the synchronous belt. The first transmission wheel on the upper side of the rotating rod meshes with the second transmission wheel of the movable shaft, which can drive the cover plate to move along the rotating seat.

[0012] 2. Because the rotating shaft has a threaded structure inside and is threaded with the threaded rod, when the rotating shaft rotates, the threaded rod rotates synchronously. When the threaded rod rotates, it drives the stabilizing component to press the upper surface of the battery, thereby fixing the battery. At the same time, the anti-tamper cover on the cover plate closes, and the rubber gasket enhances the sealing and stability. The cover plate flips upward, and the rotating rod moves horizontally in the guide groove. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] like Figures 1-4 As shown, the present invention proposes an anti-tamper screw component for electric vehicle batteries, including a battery compartment 1, a placement groove 2, an anti-tamper mechanism 3, a control compartment 4, and a stabilizing component 5. The battery compartment 1 has a placement groove 2, and the placement groove 2 is provided with a control compartment 4. A battery 6 is detachably placed in the placement groove 2 on one side of the control compartment 4. The stabilizing component 5 is placed on the upper side of the battery 6. A threaded anti-tamper mechanism 3 is provided between the placement groove 2 and the battery 6.

[0020] In an optional embodiment, the anti-tamper mechanism 3 includes a cover plate 301, a movable shaft 302, a guide groove 303, a transmission groove 304, a knob 305, a rotating seat 306, a threaded rod 307, a rotating shaft 308, a first synchronous pulley 309, a synchronous belt 310, a second synchronous pulley 311, a rotating rod 312, a first transmission wheel 313, and a second transmission wheel 314. The rotating seat 306 is provided in the placement groove 2, and the rotating shaft 308 is movably connected to the rotating seat 306. The cover plate 301 is movably connected to the rotating seat 306 through the rotating shaft 308. The cover plate 301 is symmetrically provided with guide grooves 303, and the placement groove 2 is symmetrically provided with grooves. The rotating shaft 308 is movably connected to the grooves. The rotating shaft 308 has a threaded structure, and the rotating shaft 308 is movably connected to the threaded rod 307. The stabilizing member 5 and the threaded rod 307 are threadedly engaged.

[0021] Since the rotating shaft 308 has a threaded structure inside and is threadedly engaged with the threaded rod 307, when the rotating shaft 308 rotates, the threaded rod 307 rotates synchronously. When the threaded rod 307 rotates, it drives the stabilizing component 5 to press the upper surface of the battery 6, thereby fixing the battery. At the same time, the anti-tamper cover on the cover plate 301 closes, and the rubber gasket enhances the sealing and stability. The cover plate 301 flips upward, and the rotating rod moves horizontally within the guide groove 303.

[0022] In an optional embodiment, the battery compartment 1 is provided with a transmission groove 304, a first synchronous wheel 309 is fixedly connected to a rotating shaft 308 in the transmission groove 304, a second transmission wheel 314 is provided in the transmission groove 304 on a movable shaft 302, a rotating rod 312 is movably connected in the transmission groove 304, a first transmission wheel 313 is provided on the side of the rotating rod 312 near the second transmission wheel 314, and the first transmission wheel 313 and the second transmission wheel 314 mesh with each other;

[0023] The knob 305 drives the rotating shaft 308 to rotate. The first synchronous wheel 309 below the rotating shaft 308 drives the second synchronous wheel 311 to rotate through the synchronous belt 310. The first transmission wheel 313 on the upper side of the rotating rod 312 meshes with the second transmission wheel 314 of the movable shaft 302, which can drive the cover plate 301 to move along the rotating seat 306.

[0024] In an optional embodiment, a second synchronous pulley 311 is provided on the side of the rotating rod 312 away from the first transmission wheel 313, and a synchronous belt 310 is provided between the first synchronous pulley 309 and the second synchronous pulley 311.

[0025] In an optional embodiment, the cover plate 301 is provided with a gasket on the guide groove 303, the gasket being made of rubber material, and the cover plate 301 is provided with an anti-tamper cover near the threaded rod 307.

[0026] The working principle of this utility model is as follows: When it is necessary to install the battery, first put the battery 6 into the placement slot 2, flip the cover plate 301 to cover the battery. At this time, the cover plate 301 rotates around the rotating shaft 308 to the closed position through the rotating seat 306. During operation, the rotating shaft 308 is rotated by the external rotating rod and the rotating knob 305. The first synchronous wheel 309 below the rotating shaft 308 drives the second synchronous wheel 311 to rotate through the synchronous belt 310. The first transmission wheel 313 on the upper side of the rotating rod 312 meshes with the second transmission wheel 314 of the movable shaft 302, which can drive the cover plate 301 to move along the rotating seat 306.

[0027] Since the rotating shaft 308 has a threaded structure inside and is threadedly engaged with the threaded rod 307, when the rotating shaft 308 rotates, the threaded rod 307 rotates synchronously. When the threaded rod 307 rotates, it drives the stabilizing component 5 to press the upper surface of the battery 6, thereby fixing the battery. At the same time, the anti-tamper cover on the cover plate 301 closes, and the rubber gasket enhances the sealing and stability. The cover plate 301 flips upward, and the rotating rod moves horizontally within the guide groove 303.

[0028] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
