Description

Technical Field

[0001] This utility model relates to a battery self-locking fixing structure and an intelligent safety helmet device with the same structure, belonging to the field of battery installation technology for safety helmets. Background Technology

[0002] As is generally known, a safety helmet is a protective device used to prevent head injuries from impacts, and it is widely used in metallurgy, construction, forestry, mining, power and other fields.

[0003] Smart safety helmets evolved from traditional safety helmets by adding intelligent devices. They typically have multiple functions such as communication, lighting, photography, and cooling, and can cope with more complex and ever-changing construction sites.

[0004] Smart helmets typically use electronic components to achieve their multifunctionality, with batteries often being an essential component. Currently, existing smart helmets commonly use screws to secure batteries for stability, which often results in long assembly times in practice, affecting battery replacement efficiency and increasing manufacturing costs.

[0005] In addition, the batteries in existing smart helmets are mostly fixed on the outside of the helmet, which provides poor protection for the batteries and is not conducive to a stable power supply in harsh environments. Summary of the Invention

[0006] To overcome the above-mentioned shortcomings of the prior art, this utility model provides a battery self-locking fixing structure and an intelligent safety helmet device with the structure. The structure is simple and can realize the fast and stable fixing and unlocking of the battery, improve the battery replacement efficiency, and reduce the manufacturing cost.

[0007] One technical solution adopted by this utility model to solve its technical problem is:

[0008] A battery self-locking fixing structure, the battery including a battery casing and a battery cover; the battery self-locking fixing structure includes:

[0009] The actuating block has several posts at its inner end;

[0010] And inclined blocks, the lower end of which is provided with a linkage groove that matches the number of columns;

[0011] The actuating block and the inclined stop block are arranged at an angle in space and are connected by a column passing through the linkage groove. Actuating the actuating block can drive the inclined stop block to reciprocate in the vertical direction.

[0012] As a further optional design of this technical solution, the upper inner end of the toggle block also has a limiting protrusion, the lower end of one end of the battery cover is provided with a fixing rib, the battery shell is provided with a positioning groove, the limiting protrusion is assembled in the positioning groove and forms a self-locking socket inside for the fixing rib to abut and fix, and the inclined block is assembled in the positioning groove and is connected to the column inside through a linkage groove.

[0013] As a further optional design of this technical solution, the outer end of the toggle block has a toggle plate, which penetrates the battery casing and is located on its outer side. The two ends of the surface of the toggle plate are respectively provided with lock and unlock marks, and the middle of its surface is provided with a toggle protrusion. The space between the limiting protrusion and the toggle plate forms a self-locking socket.

[0014] As a further optional design of this technical solution, the extension and retraction direction of the inclined block and the movement direction of the toggle block form a 90° angle.

[0015] Another technical solution adopted by this utility model to solve its technical problem is:

[0016] A smart safety helmet device, comprising:

[0017] The cap liner has a battery compartment liner at its end. The inner walls of the battery compartment liner are symmetrically provided with several limiting protrusions on both sides, and a locking groove is provided at one end of the top inner wall. The limiting protrusions are slidably connected to several fixing grooves symmetrically opened on both sides of the battery casing.

[0018] A battery having the above-mentioned battery self-locking fixing structure, wherein the battery self-locking fixing structure is connected to the locking groove, and when the actuating block of the battery self-locking fixing structure is moved, when the inclined block extends out of the battery cover and slides into the locking groove, the battery is fixed to the inner liner of the battery fixing compartment; when the inclined block retracts into the battery cover and slides out of the locking groove, the battery is unlocked from the inner liner of the battery fixing compartment.

[0019] As a further optional design of this technical solution, the limiting protrusions and fixing grooves of the battery fixing compartment liner are both obliquely set and in the same direction. The oblique setting is defined as the angle between the sliding connection movement direction and the length direction of the surface is acute.

[0020] Using the above technical solutions, this utility model provides a battery self-locking fixing structure and an intelligent safety helmet device with the same structure. By setting a battery self-locking fixing structure with a toggle block and a slanted stop block, or an intelligent safety helmet device with a toggle block, a slanted stop block, and a locking groove, the toggle block can be driven to reciprocate and extend along the positioning groove, thereby achieving rapid and stable fixing and unlocking of the battery. This eliminates the need for screws on the battery or for connecting it to the mounting body with screws, improving the efficiency of battery replacement, reducing the manufacturing cost of the battery self-locking fixing structure to a certain extent, and simplifying the structure.

[0049] Example 1

[0050] Figures 1 to 4 A schematic diagram of a preferred embodiment 1 of the present invention is shown. The intelligent safety helmet device 100 includes a helmet liner 110 and a battery 120 having the battery self-locking fixing structure described in Embodiment 2. The helmet liner 110 has a battery fixing compartment liner 111 at its end. Several limiting protrusions 1111 are symmetrically arranged on the inner walls of both sides of the battery fixing compartment liner 111, and a locking groove 1112 is provided at one end of its top inner wall. The limiting protrusions 1111 are slidably connected to several fixing grooves 1212 symmetrically opened on both sides of the battery casing 121. The battery self-locking fixing structure is engaged with the locking grooves 1112. When the actuating block of the battery self-locking fixing structure is moved, and the inclined block extends out of the battery cover 122 and slides into the locking groove 1112, the battery 120 is fixed to the battery fixing compartment liner 111. When the inclined block retracts into the battery cover 122 and slides out of the locking groove 1112, the battery 120 is unlocked from the battery fixing compartment liner 111.

[0051] In practice, after the battery 120 is pushed into the battery fixing compartment liner 111, the toggle block can be moved to make the inclined block reciprocate along the positioning groove 1211. When the toggle block is at the lock mark, the inclined block and the locking groove 1112 cooperate to fix the battery 120 to the battery fixing compartment liner 111. When the toggle block is at the unlock mark, the inclined block disengages from the locking groove 1112, so that the battery 120 can be removed from the battery fixing compartment liner 111 to achieve unlocking.

[0052] Therefore, the smart safety helmet device 100 of this embodiment 1 meets the usage requirements for quick battery replacement, and also has the characteristics of simple structure, low cost, convenient installation, and stable connection, thus improving the ease of use of the device.

[0053] Preferably, in this embodiment 2, the limiting protrusion 1111 and the fixing groove 1212 of the battery fixing compartment liner 111 are both obliquely arranged and have the same direction. The oblique arrangement is defined as the angle between the sliding connection movement direction and the length direction of the surface being located being acute. The oblique arrangement design is mainly used to further optimize the battery assembly movement, making it a point-to-point contact.

[0054] More specifically, the battery retaining compartment liner 111 may be provided with four symmetrical first oblique limiting protrusions and second oblique limiting protrusions, while the battery outer casing 121 is provided with four symmetrical first oblique fixing grooves and second oblique fixing grooves. During assembly, the first oblique limiting protrusions slide into the first oblique fixing groove 1212 and abut against it, and the second oblique limiting protrusions slide into the second oblique fixing grooves and abut against them, so that the battery can be positioned on the battery retaining compartment liner 111, thereby completing the fixing of the battery on the smart safety helmet device 100 based on the battery self-locking fixing structure.

[0055] Example 2

[0056] Figures 5 to 9 A schematic diagram of a preferred embodiment 2 of the present invention is shown. The battery self-locking fixing structure 123 in the figure includes a toggle block 1231 and a slanted stop block 1232. The battery 120 includes a battery shell 121 and a battery cover plate 122. The inner end of the toggle block 1231 has a plurality of columns 1231-1. The lower end of the slanted stop block 1232 is provided with a linkage groove 1232-1 with the same number of columns 1231-1. The toggle block 1231 and the slanted stop block 1232 are arranged at an angle in space and are connected by the columns 1231-1 passing through the linkage groove 1232-1. Toggle the toggle block 1231 can drive the slanted stop block 1232 to reciprocate in the vertical direction.

[0057] In this embodiment 2, the battery 120 can be a battery pack structure mainly composed of a battery outer shell 121 and a battery cover plate 122.

[0058] In use, the movable actuating block 1231 drives the column 1231-1 to slide within the linkage groove 1232-1, thereby causing the inclined stop block 1232 to reciprocate and extend, thus achieving a self-locking action and achieving the purpose of fixing and unlocking. This not only overcomes the shortcomings of fixing batteries with screws in the existing technology, but also enables quick and stable fixing and removal of the battery pack structure, improving battery replacement efficiency and offering advantages such as simple structure and low manufacturing cost.

[0059] In practical implementation, firstly, when connecting the battery pack structure to the mounting body (such as a smart safety helmet device), there is no need to install screws on the battery or connect it to the mounting body via screws, thus reducing the manufacturing cost of the battery self-locking fixing structure 123 to a certain extent. Secondly, while simplifying the structure, it allows the battery pack structure to be quickly assembled with the mounting body. More specifically:

[0060] The inclined block 1232 can reciprocate along the positioning groove 1211. When the battery pack structure is installed into the mounting body (e.g., the battery fixing compartment liner of a smart safety helmet device), the inclined block 1232 can extend and lock onto the mounting body (e.g., the inclined block 1232 extends and settles into the locking groove, fixing the battery pack structure to the battery fixing compartment liner). The inclined block 1232 can also retract to release the lock from the mounting body (e.g., the inclined block retracts and exits the locking groove, allowing the battery pack structure to be quickly removed from the battery fixing compartment liner).

[0061] Furthermore, in this embodiment 2, the upper inner end of the actuating block 1231 also has a limiting protrusion 1231-2, the lower end of one end of the battery cover 122 is provided with a fixing rib 1221, the battery outer shell 121 is provided with a positioning groove 1211, the limiting protrusion 1231-2 is assembled in the positioning groove 1211 and forms a self-locking socket inside for the fixing rib 1221 to abut and fix, the inclined block 1232 is assembled in the positioning groove 1211 and is connected to the column 1231-1 inside through the linkage groove 1232-1.

[0062] Inside the battery casing 121, the toggle block 1231 and the inclined block 1232 are assembled together using the positioning groove 1211, which realizes the linkage between the toggle block 1231 and the inclined block 1232, as well as the relative movement between the toggle block 1231 and the fixing rib 1221. That is, operating the toggle block 1231 realizes the opening and closing action of the battery 120 and the mounting body, while the insertion and removal action of the fixing rib 1221 relative to the self-locking socket realizes the quick assembly and disassembly of the battery pack structure itself.

[0063] Furthermore, in this embodiment 2, the outer end of the actuating block 1231 has an actuating plate 1231-3. The actuating plate 1231-3 penetrates the battery casing 121 and is located on its outer side. The two ends of the surface of the actuating plate 1231-3 are respectively provided with a lock mark 1231-3-1 and an unlock mark 1231-3-2. The middle of its surface is provided with an actuating protrusion 1231-3-3. The space between the limiting protrusion 1231-2 and the actuating plate 1231-3 forms a self-locking socket.

[0064] In use, by applying external force by actuating the protrusion 1231-3-3, the actuating plate 1231-3 can switch positions and move in two directions: locking mark 1231-3-1 and unlocking mark 1231-3-2. When the actuating plate 1231-3 moves to the locking mark, the battery is fixed, and the battery pack structure can be locked in the mounting body. Conversely, when the actuating plate 1231-3 moves to the unlocking mark 1231-3-2, the battery pack fixing structure can be removed.

[0065] To facilitate changing direction using the linkage groove 1232-1 set in the inclined block 1232, preferably, the extension and retraction direction of the inclined block 1232 in this embodiment 2 forms a 90° angle with the movement direction of the actuating block 1231. This allows for the most convenient and quick horizontal movement of the actuating plate 1231-3 to bring about the vertical extension and retraction of the inclined block 1232.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
