AI Technical Summary
Existing motor vehicle lamps and vehicles lack effective protection against damage during mounting, dismantling, and operation, particularly from scrubbing, and often require adhesive bonding processes that complicate assembly and may lead to visibility issues.
A protective element, such as a plastic component with a mushroom-head-like shape, is integrated into the lamp housing using a force- and form-fit mechanism, allowing secure attachment to the vehicle body without adhesive bonding, ensuring protection and maintaining positional integrity during assembly and operation.
This solution enhances protection against damage, simplifies assembly, reduces visibility disturbances, and improves the quality and longevity of the vehicle lamp system.

[0018] In summary, and in other words, the invention provides, among other things, an alignment and protection concept, in particular abrasion protection concept, for rear lights. The concept can comprise a protective element and a receptacle or attachment of the protective element to a rear light housing. The protective element can be inserted into the housing. For this purpose, the housing can have a guiding receptacle on its side, for example, in a cylindrical, round, or rectangular shape, into which the protective element is inserted and positioned. The positioning can be defined either by a housing stop within the guide or by the design of the abrasion protection element itself, for example, by a mushroom-shaped head that can project beyond a guide opening.The protective element itself can be made of a relatively dimensionally stable plastic, which, like PE, protects the vehicle body from abrasion and, unlike PE, does not produce any noise when lifted from the body. The shape of any contact geometry with the body can be customized. For example, a mushroom shape can be implemented in the area of a wrap radius within a side frame where three-dimensional point contact would be required. This shape can adapt to the vehicle's geometry thanks to its rounded head. Similarly, purely cylindrical or rectangular abrasion protection elements can be used on two-dimensional surfaces. The guide within the housing ensures the correct position within a lighting assembly and prevents the element from shifting during installation.Due to the relatively narrow guide and mounting of the protective element within the housing, compared to an alignment strip, visibility at the base of a joint is significantly reduced. Since mounting on the light side eliminates the need for a large-area adhesive application, and the protective element is held in position by the bodywork acting as a counter-bearing, detachment or slippage can be prevented even over the vehicle's lifespan, thus reducing visibility.
[0019] The invention simplifies manufacturing and / or assembly. It increases quality and / or service life. Adhesive protective films or pads are no longer necessary.
[0020] An embodiment of the invention is described in more detail below with reference to the figures, which show schematically and by way of example: Fig. 1 a motor vehicle rear light with a housing and a protective element, Fig. 2. A detailed view of the housing of a motor vehicle rear light with a protective element. Fig. 3 a housing of a motor vehicle rear light with a protective element in sectional view, Fig. 4 a protective element for a motor vehicle rear light and Fig. 5 A motor vehicle rear light with a housing and a protective element on a vehicle body in sectional view along the in Fig. Line 1, labeled AA.
[0021] Fig. Figure 1 shows a motor vehicle light 100 designed as a rear light with a housing 102 and a protective element 104. Fig. Figure 2 shows the housing 102 with the protective element 104 in detail. Fig. Figure 3 shows the housing 102 with the protective element 104 in a sectional view. Fig. Figure 4 shows the protective element 104. Fig. Figure 5 shows the motor vehicle light 100 on a vehicle body 106 in a sectional view along the in Fig. Line 1, labeled AA.
[0022] The housing 102 has a pot-like shape with a rear side 108. The front of the housing 102 is covered with a translucent disc 110, which defines the interior space of the light. The automotive light 100 is designed to be inserted into and mounted in a rear light housing 112 of the vehicle body 106, with the rear side 108 of the housing 102 then facing the vehicle body 106. The protective element 104 is designed to protect the vehicle body 106 from damage, particularly from chafing, when the automotive light 100 is mounted on the vehicle body 106 and during operation of the vehicle.
[0023] According to the invention, the protective element 104 has a longitudinal axis 114, a pin-shaped shaft section 116, and a mushroom-shaped head section 118 with a bottom surface 120 facing the shaft section 116 and a top surface 122 facing away from the shaft section 116. The shaft section 116 forms a cylindrical retaining section 124, the bottom surface 120 forms an annular contact section 126, and the top surface 122 forms a spherical cap-shaped protective section 128 of the protective element 104.
[0024] According to the invention, the housing 102 has a pin-like projecting section 130 with a free end 132 and a receptacle 134 for the protective element 104. The receptacle 134 has a bore-like shape. The free end 132 has an annular end face that forms a contact section 136.
[0025] According to the invention, the protective element 104 is held in the receptacle 134 of the housing 102 by its retaining section 124. The contact section 136 of the housing 102 and the contact section 126 of the protective element 104 are in contact with each other. Thus, the protective element 104 is positioned in a force-fit and form-fit manner in the direction of extension of the protective element's longitudinal axis 114, which is arranged coaxially with a receiving longitudinal axis, as well as transversely to the direction of extension of the protective element's longitudinal axis 114. The rear light housing 112 of the vehicle body 106 has an angled side frame 138. The vehicle light 100 can rest against the side frame 138 with the protective section 128 of the protective element 104 in a friction-free and acoustically advantageous manner. The protective element 104 is positioned between the housing 102 and the vehicle body 106.
[0026] The term "may" refers in particular to optional features of the invention. Accordingly, there are also further developments and / or embodiments of the invention that additionally or alternatively include the respective feature(s).
[0027] From the combinations of features disclosed herein, isolated features can also be selected as needed and, by dissolving any structural and / or functional relationship that may exist between the features, used in combination with other features to define the subject matter of the claim.
