Description

Technical Field

[0001] This invention relates to the field of controllers, and more specifically to an electronic controller. Background Technology

[0002] In today's era of automotive electrification and intelligence, various electronic controllers are being widely used.

[0003] Electronic controllers often require energy storage components (such as cylindrical capacitors) to ensure that they can provide power to the electronic controller or other devices in emergency situations, enabling them to operate normally for a certain period of time.

[0004] As automotive configurations continue to improve, there are higher requirements for the capacity of cylindrical energy storage elements, necessitating the installation of larger and heavier energy storage elements. Consequently, higher demands are placed on the safe securing of cylindrical energy storage elements.

[0005] In current market installation solutions, cylindrical energy storage elements are often secured to the housing using traditional clips. Because cylindrical energy storage elements have smooth cylindrical surfaces, and traditional clips typically provide line contact when engaging them, if the energy storage element is large and heavy, the traditional clips may not provide sufficient holding force when the product is impacted, causing them to flip outwards. This can lead to the energy storage element detaching and causing product failure.

[0006] Existing patent CN 221010580 U discloses a high heat dissipation electronic controller; its main protection point is how to optimize the heat dissipation treatment and disassembly and maintenance of the electronic controller; it does not clearly disclose the technical solution to the above technical problem.

[0007] Therefore, it is necessary to optimize the electronic controller in order to improve or solve at least one of the above-mentioned technical problems. Summary of the Invention

[0008] The purpose of this invention is to provide an electronic controller structure that facilitates the placement and fixing of energy storage units.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] An electronic controller includes a housing, within which an energy storage element is disposed; the energy storage element is connected to the housing via a mounting unit.

[0011] The installation unit includes an anti-detachment unit and / or a limiting unit;

[0012] The anti-detachment unit can prevent the energy storage element from detaching from the housing; the limiting unit can prevent the energy storage element from moving inside the housing.

[0013] The anti-detachment unit includes at least one anti-detachment structure; each anti-detachment structure includes a mounting base, and the mounting base is provided with a mounting cavity;

[0014] The mounting cavity is provided with a blocking mechanism; the blocking mechanism includes a self-locking protrusion on the mounting base that can be used to limit the position of the energy storage element.

[0015] The mounting base includes a bottom panel, and elastic arms are respectively provided on opposite sides of the bottom panel;

[0016] The elastic arm is connected to a blocking mechanism; the elastic arm is provided with a hollow hole for arranging the blocking mechanism.

[0017] The elastic arms on both sides of the bottom panel are symmetrically distributed, and the angle between the elastic arms and the bottom panel is an acute angle or a right angle; the elastic arms are provided with reinforcing ribs; the bottom panel is provided with a placement arc-shaped groove.

[0018] The blocking mechanism also includes a rotating plate; the rotating plate is connected to the mounting base; the rotating plate has at least one self-locking protrusion.

[0019] The rotating plate is connected to the mounting base via a rotating structure; the rotating structure includes a rotating shaft, and the rotating plate is connected to the mounting base via the rotating shaft.

[0020] After the energy storage element is assembled, the shortest distance between the self-locking protrusion and the bottom panel of the mounting base is greater than the shortest distance between the central axis of the energy storage element and the bottom panel of the mounting base; the shortest distance between the central axis of the rotating shaft and the bottom panel of the mounting base is greater than the shortest distance between the midpoint of the contact area between the self-locking protrusion and the energy storage element and the bottom panel of the mounting base; when the energy storage element tends to detach from the mounting base, the energy storage element squeezes the self-locking protrusion to rotate, and the self-locking protrusion always adheres to the energy storage element to form a reverse clamping force, preventing the energy storage element from detaching from the mounting base.

[0021] The limiting unit includes a first positioning rib and / or a positioning baffle; the energy storage element is cylindrical; the energy storage element is provided with a neck groove; the first positioning rib includes a positioning rib plate, the positioning rib plate is provided with an installation groove, and the first positioning rib can be inserted into the neck groove in the energy storage element; the positioning baffle can be arranged at the end of the energy storage element; adjacent anti-detachment units are symmetrically and parallelly distributed at intervals; the limiting unit and the adjacent anti-detachment units are distributed parallelly at intervals.

[0022] The self-locking protrusion has a self-locking protrusion guide surface and a self-locking arc surface; the vertical cross-section of the self-locking protrusion is L-shaped.

[0023] The mounting base is also provided with a pre-introduction structure; the pre-introduction structure includes a pre-introduction protrusion provided on the elastic arm; the pre-introduction protrusion has a protruding introduction surface and a protruding buckling surface; the vertical cross-section of the pre-introduction protrusion is inverted L-shaped.

[0024] Each blocking mechanism has a pre-guide protrusion on both sides; during assembly, the energy storage element first passes through the pre-guide protrusion and then presses against the self-locking protrusion.

[0025] The advantages of this invention are:

[0026] This invention discloses an electronic controller.

[0027] The electronic controller disclosed in this invention changes the traditional installation method of energy storage elements. By setting up the installation unit, this invention improves the stability and accuracy of energy storage element installation in the housing, and at the same time facilitates the installation of energy storage elements.

[0028] This invention utilizes the combined use of an anti-detachment unit and a limiting unit. The blocking mechanism arranged opposite to each other in the anti-detachment unit applies a backward pressing force to the columnar energy storage element, thereby achieving the fixed stability of the columnar energy storage element. In the limiting unit, the first positioning rib is engaged in the neck groove of the columnar energy storage element, and the positioning baffle is arranged at the end of the energy storage element, thereby achieving axial limiting of the columnar energy storage element and preventing the columnar energy storage element from moving within the shell.

[0029] Meanwhile, the combined use of the pre-introduction structure and the blocking mechanism of this invention facilitates the assembly of the columnar energy storage element. During assembly, the columnar energy storage element first compresses the pre-introduction structure, causing the elastic arm to deform in advance, and then passes over the blocking mechanism, so that the relatively arranged blocking mechanism can bind and limit the columnar energy storage element. This invention, by causing the elastic arm to deform in advance through the pre-introduction structure, can effectively avoid the micro-plastic deformation of the blocking mechanism. This ensures that the self-locking protrusion can better fit the self-locking arc surface and the columnar surface of the columnar energy storage element after the columnar energy storage element is installed in place, playing a good role in pre-tightening and fixing.

[0030] Meanwhile, through the rotational design of the blocking mechanism, after the energy storage element is assembled in place, when the product is subjected to a severe impact during application and the energy storage element tends to detach, the self-locking arc surface can drive the rotating plate to rotate around the rotating axis, so that the self-locking arc surface is always in contact with the energy storage element and forms an inverted pressing state, suppressing the tendency of the energy storage element to detach, and achieving the effect of self-locking and preventing detachment.

[0031] This invention, through the use of different numbers of anti-detachment structures, enables the installation unit to be used for fixing columnar energy storage elements of different lengths and diameters, resulting in high compatibility and flexible use.

[0032] The mounting unit and / or housing disclosed in this invention can be completed using the inclined top structure of a conventional injection mold, without the need for additional complex mold structures or special processing techniques, making it simple to manufacture and low in cost.

[0033] The installation unit disclosed in this invention adopts an independent pre-introduction structure feature, making the introduction structure and the fixing structure independent of each other, thereby avoiding the risk of plastic deformation of the fixing structure feature during installation and making the fixing more reliable; and through the rotatable structure, a self-locking inverted state is formed, providing sufficient holding force to avoid the risk of energy storage element detachment and meet the fixing requirements of larger energy storage elements.

Detailed Implementation

[0046] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0047] An electronic controller includes a housing 1, within which an energy storage element 2 is disposed. The energy storage element 2 is connected to the housing 1 via a mounting unit. The mounting unit includes an anti-detachment unit 101 and / or a limiting unit 102. The anti-detachment unit 101 prevents the energy storage element 2 from detaching from the housing 1. The limiting unit 102 prevents the energy storage element 2 from moving within the housing 1. The electronic controller disclosed in this invention changes the traditional installation method of the energy storage element 2. By setting up the mounting unit, this invention improves the stability and accurate installation of the energy storage element 2 within the housing 1.

[0048] The present invention utilizes the cooperation of the anti-detachment unit 101 and the limiting unit 102. The blocking mechanism arranged opposite to each other in the anti-detachment unit 101 applies a backward pressing force to the columnar energy storage element 2, thereby achieving the fixed stability of the columnar energy storage element 2. The first positioning rib 1021 in the limiting unit 102 is engaged in the neck groove 21 of the columnar energy storage element 2, and the positioning baffle 1022 is arranged at the end of the energy storage element 2 to achieve axial limiting of the columnar energy storage element 2 and prevent the columnar energy storage element 2 from moving within the housing 1.

[0049] The electronic controller disclosed in this invention mainly includes a housing 1 for mounting and fixing the energy storage element 2. The housing 1 is essentially a box structure, and the energy storage element 2 is provided inside the housing 1. The energy storage element 2 is a columnar part or component, and a columnar capacitor can generally be selected.

[0050] In addition, in this invention, the energy storage element 2 is connected to the housing 1 via a mounting unit; the mounting unit includes an anti-detachment unit 101 and / or a limiting unit 102; the mounting unit is essentially a restraining and limiting structure. In this invention, the anti-detachment unit 101 can prevent the energy storage element 2 from detaching from the housing 1; the limiting unit 102 can prevent the energy storage element 2 from moving within the housing 1; and the anti-detachment unit 101 and the limiting unit 102 can be used alone or both simultaneously, generally the anti-detachment unit 101 and the limiting unit 102 are used simultaneously.

[0051] In this invention, the anti-detachment unit 101 and the limiting unit 102 and the housing 1 can be an integral structure or a separate structure, and the specific connection and arrangement can be selected as needed.

[0052] In this invention, the anti-detachment unit 101 and the limiting unit 102 and the housing 1 can be integrally injection molded.

[0053] In this invention, the installation unit generally includes multiple anti-detachment units 101, and adjacent anti-detachment units 101 are required to be symmetrically and parallelly distributed at intervals; the limiting unit 102 is distributed parallelly with adjacent anti-detachment units 101 at intervals; each anti-detachment unit 101 and the limiting unit 102 are generally arranged sequentially along the central axis of the energy storage element 2 to be installed, and the limiting unit 102 is set at the end of the installation unit, mainly to cooperate with the neck groove 21 and end face of the energy storage element 2.

[0054] In this invention, the anti-detachment unit 101 includes at least one anti-detachment structure; each anti-detachment structure includes a mounting base, which is essentially a U-shaped seat, and a mounting cavity is provided on the mounting base; the mounting cavity is mainly to facilitate the installation and arrangement of the blocking mechanism and the energy storage element 2 to be installed.

[0055] In this invention, a blocking mechanism is provided in the mounting cavity; the blocking mechanism is mainly used for binding and limiting the energy storage element 2 after assembly; the blocking mechanism in this invention includes a self-locking protrusion 1016 provided on the mounting base for limiting the energy storage element 2; the self-locking protrusion 1016 is essentially equivalent to a protrusion limiting component, which plays the role of blocking and limiting.

[0056] In this invention, the mounting base includes a bottom panel 1018, on which elastic arms 1011 are respectively provided on opposite sides. The bottom panel 1018 is fixed inside the housing 1. One end of the elastic arm 1011 is connected to the bottom panel 1018, and the other end extends freely. A blocking mechanism is provided at the end of the elastic arm 1011 away from the bottom panel 1018, that is, the elastic arm 1011 is connected to the blocking mechanism. The elastic arm 1011 is provided with a hollow hole 1015 for arranging the blocking mechanism. The hollow hole 1015 plays a good role in avoiding obstruction and reducing material usage. The hollow hole 1015 makes the blocking mechanism equivalent to being embedded in the elastic arm 1011.

[0057] In this invention, the elastic arms 1011 arranged on both sides of the bottom panel 1018 are relatively symmetrically distributed, and the angle between the elastic arms 1011 and the bottom panel 1018 is an acute angle or a right angle. This invention can change the angle between the elastic arms 1011 and the bottom panel 1018 according to the magnitude of the force when the columnar energy storage element 2 is inserted, thereby changing the difficulty of inserting the columnar energy storage element 2.

[0058] Meanwhile, the elastic arm 1011 described in this invention is provided with reinforcing ribs 1012; in this invention, each elastic arm 1011 is generally provided with a reinforcing rib 1012 on each of its opposite sides. The essential function of the reinforcing rib 1012 is to enhance the strength of the elastic arm 1011, and its indirect purpose is to increase the preload force that the elastic arm 1011 can indirectly provide; the thickness and width of the reinforcing rib 1012 can be adjusted according to the magnitude of the insertion force and the magnitude of the indirect preload force.

[0059] The bottom panel 1018 of this invention is provided with an arc-shaped groove; the arc-shaped groove in this invention is essentially a sinking structure, mainly to increase the contact area with the columnar energy storage element 2, while laterally limiting the columnar energy storage element 2, and in conjunction with multiple blocking mechanisms on both sides, thereby ensuring the stability of the columnar energy storage element 2 on the mounting base.

[0060] The blocking mechanism described in this invention also includes a rotating plate 1014; the rotating plate 1014 is essentially a flat plate structure, mainly serving as a bridging structure. In this invention, the rotating plate 1014 is connected to the mounting base via a rotating shaft 1013; at the same time, the rotating plate 1014 in this invention is provided with at least one self-locking protrusion 1016; the self-locking protrusion 1016 is essentially a protrusion structure, which acts on the outer surface of the columnar energy storage element 2 to play a role in restraining and limiting its position.

[0061] The perforated hole 1015 is a partially perforated structure with reduced adhesive. After being perforated, it forms a structure in which the rotating plate 1014 is connected to the elastic arm 1011 through the rotating shaft 1013.

[0062] In this invention, the rotating plate 1014 is connected to the mounting base via a rotating structure; the rotating structure includes a rotating shaft 1013, and the rotating plate 1014 is connected to the mounting base via the rotating shaft 1013; in this invention, the rotating plate 1014, the rotating shaft 1013, and the elastic arm 1011 are integrally injection molded, and the rotation that occurs is actually the torsion of the rotating shaft 1013. Therefore, in order to achieve the rotation, the torsional strength of the rotating shaft 1013 is required to be relatively low.

[0063] In this invention, the self-locking protrusion 1016 has a self-locking protrusion 1016 guide surface 1016-1 and a self-locking arc surface 1016-2. The self-locking protrusion 1016 guide surface 1016-1 is an inclined downward arc surface, which plays a transitional guiding role. The self-locking arc surface 1016-2 is also an arc surface, which is an inwardly concave arc surface, and the curvature is the same as the contact area of ​​the outer side of the columnar energy storage element 2. The outer side of the self-locking arc surface 1016-2 contacts the columnar energy storage element 2 and partially fits it. Through the above-mentioned cooperation, the self-locking protrusion 1016 squeezes and limits the energy storage element 2.

[0064] In this invention, the self-locking protrusion 1016 has an L-shaped vertical cross section; based on this arrangement, the self-locking protrusion 1016 forms a structure with a small upper end and a large lower end, the upper end can be used for guidance, and the lower end is used for binding and limiting the energy storage element 2.

[0065] The mounting base described in this invention is also provided with a pre-guided structure; the essential function of the pre-guided structure is to guide in advance. The design of the pre-guided structure in this invention can basically avoid the micro-plastic deformation of the blocking mechanism during the assembly of the energy storage element 2; based on the setting of the pre-guided structure, the elastic arm 1011 can be pre-pressed during the assembly of the energy storage element 2, causing it to deform and drive the blocking mechanism to swing, reducing the contact between the blocking mechanism and the energy storage element 2; thereby avoiding the problem of micro-plastic deformation of the blocking mechanism caused by directly pressing the blocking mechanism to drive the elastic arm 1011 to deform.

[0066] The pre-introduction structure described in this invention includes a pre-introduction protrusion 1017 disposed on the elastic arm 1011; the pre-introduction protrusion 1017 has a protruding introduction surface 1017-1 and a protruding buckle surface 1017-2; the pre-introduction protrusion 1017 of this invention is essentially a protrusion structure disposed on the elastic arm 1011. When the energy storage element 2 is assembled, the elastic arm 1011 is deformed by squeezing the pre-introduction protrusion 1017; the protruding introduction surface 1017-1 of this invention plays an assembly guiding role, while the protruding buckle surface 1017-2 plays a avoidance role. When the columnar energy storage element 2 is installed in place, the protruding buckle surface 1017-2 maintains a certain gap with the cylindrical surface of the columnar energy storage element 2.

[0067] In this invention, the pre-introducing protrusion 1017 has an inverted L-shaped vertical cross section. Based on this design, the pre-introducing protrusion 1017 forms a structure with a large upper end and a small lower end. The large upper end can be conveniently used in conjunction with the energy storage element 2 to push the elastic arm 1011.

[0068] In this invention, viewed from the side, the self-locking protrusion 1016 and the pre-introduction protrusion 1017 have laterally overlapping portions. The smaller upper portion of the self-locking protrusion 1016 is required to correspond to the larger upper portion of the pre-introduction protrusion 1017, and the larger lower portion of the self-locking protrusion 1016 is required to correspond to the smaller lower portion of the pre-introduction protrusion 1017. With this arrangement, the guiding and restraining of the energy storage element 2 can be achieved step by step.

[0069] In this invention, each blocking mechanism is provided with a pre-introduction protrusion 1017 on both sides; the two pre-introduction protrusions 1017 are used in conjunction with a blocking mechanism to better avoid the blocking mechanism from contacting the energy storage element 2 in the early stage, and to avoid the swaying of the energy storage element 2 when it squeezes the elastic arm 1011.

[0070] In this invention, the energy storage element 2 is first introduced through the pre-introduced protrusion 1017 and then pressed against the self-locking protrusion 1016. This operation sequence can greatly reduce the external support force generated by the columnar energy storage element 2 on the self-locking protrusion 1016 during the insertion process, thereby avoiding micro-plastic deformation of the self-locking protrusion 1016.

[0071] After the energy storage element 2 is assembled, the shortest distance between the self-locking protrusion 1016 and the bottom panel 1018 of the mounting base is greater than the shortest distance between the central axis of the energy storage element 2 and the bottom panel 1018 of the mounting base; that is, after the energy storage element 2 is assembled, the self-locking protrusion 1016 is located diagonally above the energy storage element 2, and each of the self-locking protrusions 1016 is required to apply a pressing force to the energy storage element 2; by cooperating with the support force provided by the bottom panel 1018 to the energy storage element 2, the stability of the energy storage element 2 on the mounting base is ensured, and the purpose of preventing detachment is achieved.

[0072] Furthermore, this invention requires that after the energy storage element 2 is assembled, the shortest distance between the self-locking protrusion 1016 and the bottom panel 1018 of the mounting base is greater than the shortest distance between the central axis of the energy storage element 2 and the bottom panel 1018 of the mounting base; the shortest distance between the central axis of the rotating shaft 1013 and the bottom panel 1018 of the mounting base is greater than the shortest distance between the midpoint of the contact area between the self-locking protrusion 1016 and the energy storage element 2 and the bottom panel 1018 of the mounting base; simultaneously, it requires that the shortest line connecting the central axis of the rotating shaft 1013 and the central axis of the energy storage element 2 (that is, the line connecting the two center points of the cross-section of the rotating shaft 1013 and the energy storage element 2) and the shortest line between the self-locking protrusion 1016 and the energy storage element 2 is greater than the shortest distance between the self-locking protrusion 1016 and the bottom panel 1018 of the mounting base; 016 The resultant force of the applied external force is in different directions; based on the above requirements, when the energy storage element 2 tends to detach from the mounting base, the energy storage element 2 squeezes the self-locking protrusion 1016 to rotate. The self-locking protrusion 1016 is always in contact with the energy storage element 2 to form an inverted pressing force, which inhibits the energy storage element 2 from detaching from the mounting base; after the energy storage element 2 is assembled in place, when the product is subjected to a severe impact during application, causing the energy storage element 2 to tend to detach, the self-locking arc surface can drive the rotating plate 1014 to rotate around the rotating axis 1013, so that the self-locking arc surface is always in contact with the energy storage element 2 and forms an inverted pressing state, which inhibits the tendency of the energy storage element 2 to detach, and achieves the effect of self-locking to prevent detachment.

[0073] In this invention, the limiting unit 102 includes a first positioning rib 1021 and / or a positioning baffle 1022. In this invention, the first positioning rib 1021 and the positioning baffle 1022 can be used alone or in combination. In order to ensure the stability of the installation of the energy storage element 2, it is generally required that both be used at the same time.

[0074] In this invention, the energy storage element 2 is cylindrical; that is, the whole is a columnar energy storage element 2, and a neck groove 21 is provided on the energy storage element 2.

[0075] In this invention, the first positioning rib 1021 includes a positioning rib plate, and the positioning rib plate is provided with an installation groove. The installation groove plays a good role in placement and limiting, which facilitates the overlapping placement of the energy storage element 2 on the first positioning rib 1021. Subsequently, the first positioning rib 1021 can be inserted into the neck groove 21 in the energy storage element 2, thereby realizing the first-level movement limitation of the energy storage element 2.

[0076] In this invention, the positioning baffle 1022 can be arranged at the end of the energy storage element 2. The positioning baffle 1022 is essentially a vertical baffle, mainly configured at the end of the energy storage element 2. The positioning baffle 1022 fits into the end of the energy storage element 2, thereby playing a good blocking and limiting role.

[0077] Example:

[0078] This invention discloses an electronic controller; it mainly includes a housing 1, and an energy storage element 2 is provided inside the housing 1; the energy storage element 2 is connected to the housing 1 through a mounting unit; the mounting unit includes an anti-detachment unit 101 and / or a limiting unit 102; the anti-detachment unit 101 can prevent the energy storage element 2 from detaching from the housing 1; the limiting unit 102 can prevent the energy storage element 2 from moving inside the housing 1.

[0079] In this invention, the anti-detachment unit 101 includes at least one anti-detachment structure; each anti-detachment structure includes a mounting base, the mounting base having a mounting cavity; the mounting cavity having a blocking mechanism; the blocking mechanism includes a self-locking protrusion 1016 disposed on the mounting base for limiting the energy storage element 2; the limiting unit 102 includes a first positioning rib 1021 and a positioning baffle 1022; the energy storage element 2 is cylindrical; the energy storage element 2 has a neck groove 21; the first positioning rib 1021 includes a positioning rib plate, the positioning rib plate having a mounting groove, the first positioning rib 1021 being able to engage with the neck groove 21 in the energy storage element 2; the positioning baffle 1022 being able to be arranged at the end of the energy storage element 2.

[0080] In this invention, the mounting base mainly includes a bottom panel 1018, on which elastic arms 1011 are respectively provided on opposite sides; the elastic arms 1011 and the bottom panel 1018 form a vertical cross-section with a U-shaped structure; thus forming a recessed groove structure with an opening at the top; the recessed groove structure is the aforementioned mounting cavity; mainly to facilitate the placement and arrangement of the energy storage element 2.

[0081] In this invention, the anti-detachment structure includes multiple anti-detachment units 101; adjacent anti-detachment units 101 are symmetrically and parallelly distributed at intervals; the limiting unit 102 is distributed parallelly with adjacent anti-detachment units at intervals; each anti-detachment unit 101 and the anti-detachment unit are arranged along the same axis.

[0082] Meanwhile, at least one blocking mechanism is provided on each elastic arm 1011. The elastic arms 1011 of the present invention exist in symmetrical pairs. In subsequent use, one or more pairs of blocking mechanisms can be configured according to the length of the columnar energy storage element 2 that needs to be fixed. At the same time, one or more anti-detachment units 101 can be arranged as needed.

[0083] As shown in the figure, the anti-detachment unit 101 includes a bottom panel 1018, with an elastic arm 1011 on each of the opposite sides of the bottom panel 1018. The elastic arm 1011 is mainly used to arrange the blocking mechanism. The bottom panel 1018 is essentially an arc-shaped base. The elastic arm 1011 undergoes elastic deformation when the cylindrical energy storage element 2 is inserted to facilitate insertion. After the cylindrical energy storage element 2 is installed in place, it indirectly provides a pre-tightening force to achieve a fixing effect. The two elastic arms 1011 can be inclined inward or vertically arranged. The elastic arm 1011 is provided with a reinforcing rib 1012, generally with a reinforcing rib 1012 on each opposite edge of the elastic arm 1011. The reinforcing rib 1012 is used to strengthen the elastic arm 1011. The strength of the reinforcing rib 1012 is increased to enhance the preload indirectly provided by the elastic arm 1011. The thickness and width of the reinforcing rib 1012 can be adjusted according to the magnitude of the insertion force and the indirect preload. In this invention, the rotating plate 1014 is connected to the elastic arm 1011 via a rotating shaft 1013. When the columnar energy storage element 2 is inserted, it provides a central axis for rotation, facilitating the insertion of the columnar energy storage element 2. After the columnar energy storage element 2 is installed, if the product experiences an impact during application that causes the columnar energy storage element 2 to tend to come out, the rotating shaft 1013 provides a central axis for rotation, ensuring that the columnar energy storage element 2 remains in a self-locking state to prevent it from coming out. The rotating plate 1014 rotates... The rotating shaft 1013 is connected to the elastic arm 1011. When the cylindrical energy storage element 2 is inserted, the rotating plate 1014 is driven to rotate by the rotation of the rotating shaft 1013, facilitating the insertion of the cylindrical energy storage element 2. After the cylindrical energy storage element 2 is installed in place, if the cylindrical energy storage element 2 tends to detach due to impact during application, the rotating plate 1014 will rotate by the rotating shaft 1013 to keep the cylindrical energy storage element 2 in a tightly clamped state, preventing it from detaching. The elastic arm 1011 is provided with a hollow hole 1015, and the blocking mechanism is arranged in the hollow hole 1015 of the elastic arm 1011. The hollow hole 1015 allows the rotating plate 1014 to... Relatively independent of the elastic arm 1011, the rotating plate 1014 is connected to the elastic arm 1011 only through the rotating shaft 1013; the rotating plate 1014 is provided with a self-locking protrusion 1016, which has a self-locking protrusion 1016 guide surface 1016-1 and a self-locking arc surface 1016-2. The self-locking protrusion 1016 guide surface 1016-1 is used for smooth sliding into the columnar energy storage element 2 when it is inserted; the self-locking arc surface 1016-2 is used for complete contact between the columnar energy storage element 2 and the columnar surface after it is assembled in place, and provides pre-tightening force to the columnar energy storage element 2; the lower side of the self-locking arc surface 1016-2 is an arc bottom 1016-21, and the upper side is an arc top 1016-22;If the columnar energy storage element 2 tends to detach due to impact during application, the large-diameter portion of the columnar energy storage element 2 below the self-locking arc surface 1016-2 will cause the arc bottom 1016-21 of the self-locking arc surface 1016-2 to flip outward as it moves upward, causing the rotating plate 1014 to rotate around the rotation axis 1013. This will cause the arc top 1016-22 of the self-locking arc surface 1016-2 to flip inward, thereby causing the self-locking arc surface 1016-2... The reverse-clamping state is formed, which suppresses the tendency of the columnar energy storage element 2 to detach, so that the self-clamping arc surface 1016-2 is always in complete contact with the columnar surface, thus achieving the effect of self-clamping and preventing detachment; in addition, in this invention, the elastic arm 1011 is provided with a pre-guide protrusion 1017, which is not directly connected to the rotating plate 1014; the pre-guide protrusion 1017 has a protrusion guide surface 1017-1 and a protrusion reverse-clamping surface 1017-2, as shown; Figure 4 As shown; when assembling the cylindrical energy storage element 2, the cylindrical surface of the cylindrical energy storage element 2 contacts the protrusion guide surface 1017-1 of the pre-guide protrusion 1017, causing the elastic arm 1011 to flip outward. At the same time, the elastic arm 1011 drives the rotating plate 1014 to flip outward via the rotating shaft 1013, thereby allowing the cylindrical energy storage element 2 to be smoothly inserted. Simultaneously, because of the outward flipping caused by the pre-guide protrusion 1017, the external support force generated by the cylindrical energy storage element 2 on the self-locking protrusion 1016 during insertion can be greatly reduced to avoid micro-plastic deformation, thus ensuring that the self-locking protrusion 1016 can... This design ensures better fit between the columnar energy storage element 2 and the columnar surface after installation, providing good pre-tightening and fixing. After the columnar energy storage element 2 is installed, the protruding undercut surface 1017-2 of the pre-guide protrusion 1017 maintains a certain gap with the columnar surface of the columnar energy storage element 2. The bottom panel 1018 is an arc-shaped base. After the columnar energy storage element 2 is installed, it will sit on the bottom panel 1018. At the same time, combined with the pre-tightening force provided by the self-clamping arc surface 1016-2 of the self-clamping protrusion 1016, the columnar energy storage element 2 is firmly fixed on the bottom panel 1018.

[0084] like Figure 1 As shown, the limiting unit 102 mainly includes a first positioning rib 1021 and a positioning baffle 1022. The first positioning rib 1021 matches the neck groove 21 of the columnar energy storage element 2 when it is inserted, thus positioning it in the axial direction. After the columnar energy storage element 2 is installed in place, the entire first positioning rib engages with the neck groove 21 of the columnar energy storage element 2, thus limiting the columnar energy storage element 2 in the axial direction and preventing it from moving in the axial direction due to impact during application. The positioning baffle 1022 is arranged at the end of the energy storage element 2, and its function is to provide double protection against movement of the columnar energy storage element 2 in the axial direction.

[0085] Working process and working principle:

[0086] As shown in the figure, when assembling the columnar energy storage element 2, the first positioning rib 1021 positions the neck groove 21 of the columnar energy storage element 2 to ensure its position accuracy in the installation axis direction; when the columnar energy storage element 2 is further inserted downwards, the cylindrical surface of the columnar energy storage element 2 will first contact the protruding guide surface 1017-1 of the pre-guide protrusion 1017 of the anti-detachment unit 101 and cause the elastic arm 1011 to flip outwards (as shown in the figure). Figure 5 (Indicated by the arrow direction) At the same time, the elastic arm 1011 will drive the rotating plate 1014 to flip outward through the rotating shaft 1013, so that the columnar energy storage element 2 can be smoothly installed; at the same time, because of the outward flip driven by the pre-introducing protrusion 1017, the external support force generated by the columnar energy storage element 2 on the self-locking protrusion 1016 during the insertion process can be greatly reduced to avoid micro-plastic deformation, thereby ensuring that the self-locking protrusion 1016 can better connect the self-locking arc surface 1016-2 and the columnar energy storage element 2 after it is installed in place. The complete fit of the surfaces provides good pre-tightening and fixation. During the insertion of the columnar energy storage element 2, its cylindrical surface and the self-locking arc surface 1016-2 of the self-locking protrusion 1016 cooperate until they are completely fitted. As the columnar energy storage element 2 is inserted, the self-locking protrusion 1016 will rotate slightly around the rotation axis 1013 along with the rotating plate 1014. After the columnar energy storage element 2 is completely seated on the bottom panel 1018, the self-locking arc surface 1016-2 is still in a state of complete fit with the cylindrical surface of the columnar energy storage element 2.

[0087] like Figure 6 As shown, after the columnar energy storage element 2 is installed in place, the first positioning rib 1021 in the limiting element will fully engage with the neck groove 21 of the columnar energy storage element 2 (as shown). Figure 7 As shown in the sectional view, this will limit the columnar energy storage element 2 in the axial direction, preventing the columnar energy storage element 2 from moving in the axial direction due to impact during application; at the same time, the positioning baffle 1022 also plays a dual protective role in preventing the columnar energy storage element 2 from moving in the axial direction.

[0088] like Figure 8 The diagram illustrates the state of the columnar energy storage element 2 after it has been installed into the mounting unit. At this point, the self-locking arc surface 1016-2 of the self-locking protrusion 1016 is completely in contact with the cylindrical surface of the columnar energy storage element 2, providing a preload force to the columnar energy storage element 2 (e.g., ...). Figure 8As shown in F), the columnar energy storage element 2 is firmly fixed to the bottom panel 1018. In this state, the bottom 1016-21 of the self-locking arc surface 1016-2 of the self-locking protrusion 1016 is located above the widest diameter of the columnar energy storage element 2, and the protruding undercut surface 1017-2 of the pre-guided protrusion 1017 maintains a certain gap with the cylindrical surface of the columnar energy storage element 2 to avoid overfitting and the self-locking arc surface 1016-2 of the self-locking protrusion 1016 and the cylindrical surface of the columnar energy storage element 2 failing to achieve perfect fit.

[0089] like Figure 9 As shown, if the product is subjected to a severe impact during application, causing the columnar energy storage element 2 to tend to detach, the large-diameter portion of the columnar energy storage element 2 located below the self-locking arc surface 1016-2 will cause the arc bottom 1016-21 of the self-locking arc surface 1016-2 to flip outward as it moves upward. This will cause the rotating plate 1014 to rotate around the rotating axis 1013, thereby causing the arc top 1016-22 of the self-locking arc surface 1016-2 to flip inward. This results in the self-locking arc surface 1016-2 forming an inverted pressing state, suppressing the tendency of the columnar energy storage element 2 to detach. This ensures that the self-locking arc surface 1016-2 remains completely in contact with the cylindrical surface of the columnar energy storage element 2, achieving a self-locking and anti-detachment effect (rotation direction as shown). Figure 9 (As indicated by the arrow).

[0090] The installation unit disclosed in this invention can be used as a standalone component and assembled with the columnar energy storage element 2 to form an energy storage module; alternatively, this structure can be integrated into the product housing 1 for the fixed connection of the columnar energy storage element 2. Furthermore, depending on the length of the columnar energy storage element 2 to be assembled and fixed, one or more anti-detachment units 101 can be configured to meet the requirements of the fixing force.

[0091] The present invention has the following advantages:

[0092] Low cost and simple manufacturing: The anti-detachment unit 101 of the present invention can be completed by the inclined top structure of a conventional injection mold, without the need for additional complex mold structure or special processing technology, which makes it simple to manufacture and low in cost.

[0093] Flexible and highly compatible: This anti-detachment unit 101 can be used to fix cylindrical energy storage elements 2 of different lengths and diameters, with high compatibility and flexible use.

[0094] Reliable installation: The anti-detachment unit 101 adopts an independent pre-introduction structure feature, which makes the introduction structure and the fixing structure independent of each other, thereby avoiding the risk of plastic deformation of the fixing structure feature during installation and making the fixation more secure.

[0095] High holding force: The anti-detachment unit 101 has a rotatable structure that forms a self-locking inverted state, providing sufficient holding force to avoid the risk of the columnar energy storage element 2 detaching and to meet the fixing requirements of larger columnar energy storage elements 2.

[0096] Obviously, the specific implementation of this invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
